Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a communication terminal that records and displays caller ID information that arrives from a line when an incoming call is received.
[0002]
[Prior art]
As communication terminals that record and display caller ID information that arrives from the line when an incoming call is received, for example, caller ID display adapters and telephones with caller ID display functions have been commercialized.
[0003]
In this type of communication terminal, if the correspondence between the caller ID information and the caller information indicating the name is registered in advance, the caller corresponding to the caller ID information that has arrived from the line at the time of incoming call Some have recorded and displayed information.
[0004]
In addition, when the user of the communication terminal is absent at the time of the incoming call, that is, when the user of the communication terminal has not responded, there is also one that detects that fact and further displays the number of unanswered incoming calls. .
[0005]
Note that this type of communication terminal simply records the caller ID information in the order of incoming calls, and records the caller ID information for the latest incoming calls as many as the number of records that can be recorded in the recording area. It is common to be done.
[0006]
[Problems to be solved by the invention]
In the conventional communication terminal described above, when the caller performs a disconnection operation when the user has not responded, the caller ID information is recorded, so that the user can view the caller ID information later. Although it is possible to know that there is an incoming call and the caller, it is impossible to judge whether the incoming call is an important incoming call that needs to be returned. In other words, from the standpoint of the caller, if the callee is not answered, the user's intention (the importance level of the call) cannot be transmitted.
[0007]
If the caller has a high level of importance, the caller may try to keep calling until the other party answers, and as a result, the period until the other party determines that the other party is absent and performs a disconnection operation. Becomes longer.
[0008]
Therefore, the period during which the caller continues to call, that is, the duration period of the called state in the communication terminal can be used as judgment material for measuring the importance of the call from the caller.
[0009]
Further, in the conventional communication terminal described above, the caller ID information is simply recorded in the order of arrival, and the caller ID information unnecessary for the user of the communication terminal such as an erroneous call is also recorded. End up.
[0010]
Since the recording area for recording the caller ID information is limited, it is preferable to preferentially record the caller ID information for an incoming call having a high importance level of the call from the caller. If the duration of the called state at the terminal is used as a decision material for measuring the importance of the call from the caller, preferential recording can be realized.
[0011]
An object of the present invention is to realize a user merit by using a duration of a called state in a communication terminal in a communication terminal that records and displays caller ID information coming from a line.
[0012]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a first aspect as follows:
Detecting means for detecting caller ID information arriving from the line at the time of an incoming call;
Measuring means for measuring the duration of the called state;
A recording unit that records the caller ID information detected by the detection unit and the measurement value of the measurement unit in association with each other;
There is provided a communication terminal comprising display means for displaying the recorded contents of the recording means.
[0013]
According to the first aspect, even if the user has not answered at the time of the incoming call, he / she can feel the importance of the call from the caller and make a return call by looking at the displayed measurement value later. Can take action. Specifically, as the measured value is larger, it means that the caller has called for a longer period, so it can be determined that the call is an important call.
[0014]
Therefore, according to the 1st aspect, since the judgment material which measures the importance of the call from a sender | caller can be given to a user, a user merit can be implement | achieved.
[0015]
Moreover, the present invention provides the second aspect as the second aspect,
The recording means is
There is provided a communication terminal characterized in that no recording is performed when the measured value of the measuring means is not more than a predetermined threshold value.
[0016]
According to the second aspect, the recording area can be used effectively. Specifically, caller number information of a caller who has called for a longer time than a predetermined period can be preferentially recorded in the recording area.
[0017]
Therefore, according to the second aspect, since it is not necessary to use a large-capacity memory, the communication terminal can be provided at a low cost, so that the user merit can be realized.
[0018]
In addition, the present invention provides a third aspect, in the first aspect,
Further comprising caller number storage means for storing pre-registered caller number information,
The recording means is
If the measured value of the measuring means is equal to or less than a predetermined threshold value and the caller number storage means does not store the caller number information detected by the detecting means, no recording is performed. A communication terminal characterized by this is provided.
[0019]
According to the third aspect, the caller number information registered in advance is preferentially recorded in the recording area regardless of the duration of the called state, and other caller number information is recorded. As in the second mode, the caller ID information of the caller can be preferentially recorded in the recording area for longer than a predetermined period.
[0020]
In any of the first to third aspects,
The recording means is
If there is no free space at the time of recording, the recorded content corresponding to the smallest measured value among the measured values smaller than the measured value to be recorded can be deleted.
[0021]
In any of the first to third aspects,
The display means is
The display mode can be changed according to the range to which the measurement value of the measuring means belongs.
[0022]
In any of the first to third aspects,
Further comprising character storage means for storing a range of measurement values registered in advance and character information in association with each other,
The display means is
Instead of the measurement value of the measurement means, the character information stored in the character storage means can be displayed in association with the range to which the measurement value belongs.
[0023]
Furthermore, in any of the first to third aspects,
Caller number storage means for storing caller number information registered in advance;
A character storage means for storing a range of measurement values registered in advance and character information in association with each other;
The display means is
When the sender number storage means stores the sender number information detected by the detection means, the character storage means is associated with the range to which the measurement value belongs instead of the measurement value of the measurement means. The character information stored in can be displayed.
[0024]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0025]
(First embodiment)
First, a first embodiment will be described with reference to FIGS.
[0026]
FIG. 1 is a block diagram illustrating a configuration of a communication terminal according to the first embodiment.
[0027]
In the first embodiment, it is assumed that the communication terminal is a caller number display adapter interposed between the fixed telephone and the analog network switch.
[0028]
In FIG. 1, 100 is a caller ID display adapter, 101 is a line control circuit, 102 is an ID reception circuit, 103 is an incoming call detection circuit, 104 is a main control unit, 105 is a memory, 106 is an operation unit, and 107 is a display unit. is there.
[0029]
The line control circuit 101 forms a communication path on the analog line with the analog network switch, and the ID receiving circuit 102 receives caller ID information that arrives from the analog line when an incoming call is received. The incoming call detection circuit 103 detects a call signal indicating an incoming call activation (transition to a called state).
[0030]
The main control unit 104 controls the operation of the entire caller ID display adapter 100 by executing a program stored in the memory 105, or executes the operation according to the first embodiment. That is, in the first embodiment, the main control unit 104 measures the duration of the called state and records the measured value in the memory 105 in association with the caller ID information received by the ID receiving circuit 102. It is supposed to be.
[0031]
The operation unit 106 is for the user of the caller number display adapter 100 to instruct reading of the recorded content in the memory 105, and the display unit 107 is for displaying the recorded content read from the memory 105. belongs to.
[0032]
2 and 3 are sequence diagrams showing a basic sequence of a caller ID notification service in an analog network (PSTN).
[0033]
FIG. 2 shows a basic sequence from when a caller responds to a call from the caller, transitioning to a busy state, and then disconnecting by the caller's call termination operation. 4 shows a basic sequence from when the caller is not answered to the call from, and until the call is abandoned by the caller's call termination operation.
[0034]
As shown in FIG. 2, when the caller performs a call (off-hook + dial) operation, an activation signal (CAR) arrives from the analog network switch to the caller number display adapter 100. When 100 receives the activation signal, it returns a primary response signal.
[0035]
Subsequently, since the caller ID information is received from the analog network switch that has detected the reception of the primary response signal to the caller ID display adapter 100, the caller ID display adapter 100 receives the caller ID information. If successful, a reception completion signal is returned.
[0036]
Subsequently, since the call signal (IR) arrives at the caller ID display adapter 100 from the analog network switch that has detected the reception completion signal, the caller ID display adapter 100 detects the reception of the call signal. This means that the state has been shifted to the called state, so that the call signal is relayed to the fixed telephone at the rear and the bell is ringed by the fixed telephone. At this time, a ringing tone (RBT) is transmitted from the analog network switch to the caller.
[0037]
When the user (called party) of the fixed telephone whose ringing has performed a response (off-hook) operation, the called state of the caller ID display adapter 100 is canceled, and the caller ID display adapter 100 is connected to the analog network switch from the fixed telephone. The secondary response signal transmitted to is relayed.
[0038]
As a result, the call signal that has arrived from the analog network switch to the caller ID display adapter 100 is stopped, and a communication path is formed on the analog line between the analog network switch and the caller ID display adapter 100. As a result, the calling party and the called party shift to a busy state.
[0039]
Now, when the caller performs an end-of-call (on-hook) operation in a busy state, a busy tone (BT) comes from the analog network switch to the caller number display adapter 100. When 100 detects the reception of the busy tone, it relays the busy tone to the fixed telephone at the back.
[0040]
When the user (called party) of the fixed telephone who hears the busy tone performs an end of call (on-hook) operation, the caller ID display adapter 100 relays the end signal transmitted from the fixed telephone to the analog network switch. To do.
[0041]
As a result, the communication path formed on the analog line between the analog network switch and the caller ID display adapter 100 is disconnected.
[0042]
As shown in FIG. 3, the sequence from when the caller performs a call operation to when the caller number display adapter 100 rings the fixed telephone bell is the same as in FIG.
[0043]
Here, since the user (called party) of the landline telephone that rings the ring does not answer (off-hook) and does not answer, the caller performs an end-of-call (on-hook) operation to abandon the call. ing.
[0044]
When the caller performs the call termination operation, the call signal that has arrived from the analog network switch to the caller ID display adapter 100 is stopped, and the called state of the caller ID display adapter 100 is released.
[0045]
The user of the fixed telephone is the same as the user of the caller ID display adapter 100.
[0046]
The basic sequence shown in FIGS. 2 and 3 is the same as the conventional basic sequence.
[0047]
In the first embodiment, the caller ID display adapter 100 measures the duration of the called state. The duration of the called state is the basic shown in FIGS. 2 and 3. This corresponds to a period in which a call signal has arrived from the analog network switch to the caller ID display adapter 100 in the sequence.
[0048]
In practice, the call signal is a signal that alternately repeats about 1.0 second ringing and about 2.0 second pause as shown in FIG. As shown in FIG. 5, the number of ringing (the number of ringing of the bell) from the time when the first ringing is started to the point when it is clearly determined that the ringing has stopped is used as a measured value, or as shown in FIG. The elapsed time from the time when the first ringing is started to the time when it is clearly determined that the ringing has stopped can be used as the measured value.
[0049]
In the following, description will be made by taking as an example a case where the number of ringing of the bell from the time when the first ringing is started to the point when it is clearly determined that the ringing has stopped is used as a measured value.
[0050]
7 and 8 are process flowcharts of a process in which the caller ID display adapter 100 measures the number of rings of the bell.
[0051]
This process is realized by a periodic program that is activated at a predetermined period (in this example, 0.08 seconds).
[0052]
As shown in FIG. 7, in the caller ID display adapter 100, first, the main control unit 104 determines the output from the incoming call detection circuit 103 (step 701).
[0053]
As described with reference to FIG. 2 and FIG. 3, when the caller performs a call operation, an activation signal arrives from the analog network switch to the caller number display adapter 100. As shown in FIG. 4, the signal repeats alternately about 0.5 seconds of ringing and about 0.5 seconds of pause. In the caller ID display adapter 100, the incoming call detection circuit 103 arrives from the analog network switch. The activation signal is input, and the sounding and resting states are output to the main control unit 104 as signal levels.
[0054]
Therefore, when the output of the incoming call detection circuit 103 is “L (low level)” indicating that the main control unit 104 is in a dormant state (step 701), the main control unit 104 performs the processing shown in the flowchart of FIG. move on.
[0055]
Further, when the output of the incoming call detection circuit 103 is “H (high level)” indicating that the main control unit 104 is in a ringing state (step 701), the main control unit 104 measures the number of times the ringing state has been reached. It is determined whether or not the value of the variable MA for “0” is “0” (step 702). If the value of the variable MA is “0”, the activation signal detection process is executed.
[0056]
That is, in the activation signal detection process, the main control unit 104 substitutes the value of the variable MB for measuring the number of times of hibernation into the variable MB ′ (step 703), and the value of the variable MB ′ is “ 6 ”(step 704), and when the value of the variable MA ′ is“ 6 ”(step 705), the sleep state is 0.08 seconds × 6 (times) = 0.48 seconds (about 0). This means that the ringing state lasted for 0.08 seconds x 6 (times) = 0.48 seconds (approximately 0.5 seconds) after it lasted for. The line control circuit so as to initialize the value of the variable MC for measuring the number of ringing of the bell to "0" (step 706) and to return the primary response signal to the analog network switch. After requesting to 101 (step 707), this process is terminated. Note that the value of the variable MA is assigned to the variable MA ′ in step 802 of FIG.
[0057]
Further, when both the value of the variable MB ′ and the value of the variable MA ′ are not “6” (steps 704 and 705), the main control unit 104 initializes the value of the variable MB to “0” ( In step 708), “1” is added to the value of the variable MC (step 709), and then the process proceeds to step 710.
[0058]
As shown in FIG. 4, the call signal arriving from the analog network switch to the caller ID display adapter 100 is a signal that alternately repeats ringing for about 1.0 seconds and pause for about 2.0 seconds. In the caller ID display adapter 100, the incoming call detection circuit 103 receives the activation signal that has arrived from the analog network switch in the same manner as the activation signal, and uses the ringing and dormant state as the signal level as the main control unit. To 104.
[0059]
Therefore, when proceeding to Step 708 and Step 709, the main control unit 104 determines that it has detected reception of the paging signal, not reception of the activation signal, and adds “1” to the value of the variable MC. The measurement value of the ringing frequency of the bell is updated.
[0060]
Further, even when the variable MA is not “0” (step 702), the main control unit 104 proceeds to step 710, adds “1” to the variable MA in step 710, and then ends this process.
[0061]
On the other hand, when the output of the incoming call detection circuit 103 is “L (low level)” indicating that the main control unit 104 is in a dormant state (step 701), first, as shown in FIG. Then, it is determined whether or not the value of the variable MB is “0” (step 801). If the value of the variable MB is “0”, the activation signal detection process is executed.
[0062]
That is, in the activation signal detection process, the main control unit 104 substitutes the value of the variable MA into the variable MA ′ (step 802), the value of the variable MA ′ is “6” (step 803), When the value of the variable MB ′ is “6” (step 804), the ringing state continues for 0.08 seconds × 6 (times) = 0.48 seconds (about 0.5 seconds), and then the sleep state. Means that it has continued for 0.08 seconds × 6 (times) = 0.48 seconds (about 0.5 seconds), so it is determined that the activation signal has been received, and the value of the variable MC is set to “ At the same time, the line control circuit 101 is requested to return a primary response signal to the analog network switch (step 806), and then the process proceeds to step 809. Note that the value of the variable MB is assigned to the variable MB ′ in step 703 of FIG.
[0063]
Further, when both the value of the variable MA ′ and the value of the variable MB ′ are not “6” (steps 803 and 804), the main control unit 104 initializes the value of the variable MA to “0” ( The process proceeds to step 807) and step 808.
[0064]
Even when the variable MB is not “0” (step 801), the main control unit 104 proceeds to step 808, adds “1” to the variable MB in step 808, and then proceeds to step 809.
[0065]
In step 809, the main control unit 104 determines whether or not the variable MB is “30”. If the variable MB is “30”, the sleep state is 0.08 seconds × 30 (times) = This means that it has continued for 2.4 seconds (approximately 2.0 seconds + α), so it is determined that the ringing signal reception stop has been detected, and the value of the variable MC, that is, the number of ringing of the bell is received as the ID reception. Corresponding to the caller ID information received by the circuit 102, it is recorded in the memory 105 (step 810), the value of the variable MC is initialized to “0” (step 811), and this processing is terminated.
[0066]
Note that the values of various variables used in FIGS. 7 and 8 are stored in the memory 105 and are taken over by the present process performed in the next cycle.
[0067]
In step 810 of FIG. 8, the main control unit 104 records the number of ringing bells and caller ID information in the memory 105 in association with each other as shown in FIG.
[0068]
In FIG. 10, 1001 is an entry number, 1002 is an incoming date and time (date and time when reception of a ringing signal is detected), 1003 is caller number information, and 1004 is the number of rings of a bell.
[0069]
The latest recorded content (latest entry) of the recorded content shown in FIG. 10 is read from the memory 105 and displayed on the display unit 107, for example, as shown in FIG.
[0070]
11, 1101 to 1104 correspond to 1001 to 1004 in FIG. 10, respectively. In FIG. 11, reference numerals 1005 and 1006 denote reading buttons, and the user of the caller ID display adapter 100 can display a desired entry by pressing the reading buttons 1005 and 1006. ing.
[0071]
Thereby, even if the user of the caller number display adapter 100 does not answer at the time of the incoming call, the user can increase the importance of the call from the caller by looking at the number of ringing of the bell displayed on the display unit 107 later. You can take actions such as feeling and calling back. Specifically, the larger the number of ringing rings, the more the caller has called for a longer period, so it can be determined that the call is more important.
[0072]
Also, from the standpoint of the caller, in particular, when the callee is not answered, the user's intention (the importance of the call) can be conveyed without incurring a call charge.
[0073]
Therefore, according to the first embodiment, it is possible to provide the user of the caller number display adapter 100 with the determination material for measuring the importance of the call from the caller, so that the user merit can be realized.
[0074]
In the first embodiment, as shown in FIG. 12, caller number information 1201 and caller information (for example, name) 1202 registered in advance by the user of the caller number display adapter 100 are associated with each other and stored in memory. In step 810 of FIG. 8, the main control unit 104 stores the same caller number information 1201 as the caller number information received by the ID receiving circuit 102. Corresponding caller information 1202 may be recorded in the memory 105 instead of the caller number information 1003.
[0075]
By the way, in the example of FIG. 10, since it is assumed that a maximum of 10 entries can be recorded, the main control unit 104, as in the prior art, has the latest entry when there is no empty entry at the time of recording. In order to record the entry about the incoming call, the oldest entry may be deleted. In the first embodiment, the number of rings of the bell is set according to the importance of the call from the caller. Since there is no empty entry at the time of recording, the main control unit 104 searches for an entry with the smallest number of ringing of the bell, and the number of ringing of the bell If it is less than or equal to the number of rings, the found entry can be deleted.
[0076]
Furthermore, in the first embodiment, since the number of ringing of the bell is used as a determination material for measuring the importance of the call from the caller, the main control unit 104 determines the number of ringing of the bell in advance. If it is less than or equal to the threshold value, recording is not performed, so that only an entry for an incoming call having a high importance level of the call from the caller is recorded, and the memory 105 is effectively used. be able to.
[0077]
In order to do this, step 810 in FIG. 8 may be changed to the process shown in FIG.
[0078]
That is, the main control unit 104 determines whether or not the value of the variable MC is larger than a predetermined threshold (for example, “5”) as shown in FIG. Step 1301) Only when it is large, the number of ringing of the bell (value of variable MC) and caller ID information are associated and recorded in the memory 105 (Step 1302).
[0079]
According to this example, only an entry for an incoming call in which the bell rings 6 times or more (an incoming call that has been called until the caller hears the ringing sound 6 times or more) is recorded in the memory 105.
[0080]
In addition, when only the entry about the incoming call with high importance of the call from the caller is recorded, when the caller makes a call from a mobile phone such as a mobile phone or a PHS terminal, The call may be interrupted against the intention of the caller. Therefore, when the caller ID information represents a mobile phone number such as a mobile phone or a PHS terminal, the main control unit 104 records even if the value of the variable MC is equal to or less than the threshold value. It may be.
[0081]
In order to do this, step 810 in FIG. 8 may be changed to the process shown in FIG.
[0082]
That is, instead of step 810 in FIG. 8, the main control unit 104, when the caller ID information received by the ID receiving circuit 102 represents the mobile phone number as shown in FIG. 14 ( Step 1401), the number of ringing of the bell (value of variable MC) and caller number information are associated and recorded in the memory 105 (Step 1403), and the caller number information received by the ID receiving circuit 102 is the mobile object. When the telephone number is not represented (step 1401), only when the value of the variable MC is larger than a predetermined threshold (for example, “5”) (step 1402), the number of ringing of the bell (of the variable MC) Value) and caller ID information are associated with each other and recorded in the memory 105 (step 1403).
[0083]
In addition, when only the entry about the incoming call having a high importance level of the call from the caller is recorded, the caller number information registered in advance by the user of the caller number display adapter 100 is stored in the memory 105. Then, the main control unit 104 records the same caller ID information as the caller ID information stored in the memory 105 even if the value of the variable MC is less than or equal to the threshold value. Also good.
[0084]
In order to do this, step 810 in FIG. 8 may be changed to the process shown in FIG.
[0085]
That is, instead of step 810 in FIG. 8, the main control unit 104 matches the caller number information received by the ID receiving circuit 102 with the caller number information stored in the memory 105 as shown in FIG. 15. If so (step 1501), the number of ringing of the bell (value of variable MC) and caller number information are associated and recorded in the memory 105 (step 1503), and the caller number received by the ID receiving circuit 102 is recorded. If the information does not match the caller ID information stored in the memory 105 (step 1501), only when the value of the variable MC is greater than a predetermined threshold (eg, “5”) (step 1502). ), The number of ringing of the bell (value of variable MC) and the caller ID information are associated and recorded in the memory 105 (step 1503).
[0086]
In the first embodiment, when the recorded content shown in FIG. 10 is read and displayed on the display unit 107, the display mode may be changed according to the number of ringing of the bell.
[0087]
For example, in the first case where the number of ringing of the bell is “1” to “5”, in the second case where the number of ringing of the bell is “6” to “10”, the number of ringing of the bell is “11” or more. The speed of the blinking cycle at the time of display is divided into three cases of the third case so that the first case> the second case> the third case, the number of ringing of the bell The user can visually appeal the size, that is, the importance of the call from the caller to the user of the caller ID display adapter 100.
[0088]
For example, if the display unit 107 can perform color display, the display color can be changed.
[0089]
Furthermore, in the first embodiment, the main control unit 104 counts the number of ringing of the bell (variable) both when the caller performs a response operation and when the caller performs a call end operation. MC value) and caller number information are recorded in the memory 105 in association with each other. However, when the callee performs a response operation, the user of the caller number display adapter 100 moves the display unit 107. Since it is considered that the display content has been confirmed, the content recorded in the memory 105 may be deleted at the end of the call or at the next recording time. In order to delete at the next recording, it is necessary to record that there is a response.
[0090]
(Second Embodiment)
Next, a second embodiment will be described with reference to FIGS.
[0091]
In the second embodiment, when the number of ringing of the bell (value of variable MC) recorded in the memory 105 is displayed on the display unit 107 in the first embodiment, processing is performed. Hereinafter, only differences from the first embodiment will be described.
[0092]
Specifically, in the second embodiment, when the main control unit 104 reads out the number of ringing of the bell (value of the variable MC) and caller number information from the memory 105 and displays them on the display unit 107, FIG. The processing shown in FIG. 16 is performed.
[0093]
That is, as shown in FIG. 16, the main control unit 104 determines whether or not the value of the variable MC to be displayed is larger than a predetermined threshold (for example, “5”) (step 1601). ”Or less, display is performed according to the first pattern (step 1602). If it is greater than“ 5 ”, the value of the variable MC to be displayed is further set to a predetermined threshold value (for example, It is determined whether it is larger than “10”) (step 1603).
[0094]
When the value of the variable MC to be displayed is “10” or less (step 1603), display according to the second pattern is performed (step 1604), and when it is larger than “10” (step 1603). ), Display according to the third pattern is performed (step 1605).
[0095]
In addition, as the display according to the first pattern, for example, as shown in FIG. 17, instead of the value of the variable MC, character information “There was a phone call” can be displayed. As the display according to the second pattern, for example, as shown in FIG. 18, instead of the value of the variable MC, text information “There was a phone that seems to be important” is displayed. As a display according to the third pattern, for example, as shown in FIG. 19, instead of the value of the variable MC, the text information “There was a phone that seems to be very important” is displayed. You can make it.
[0096]
The reason why the display examples shown in FIGS. 17 to 19 are used is that when the value of the variable MC is “5” or less, the bell rings for 5 times or less, and the value of the variable MC is “6” to If it is “10”, it means that the call has been ringed 6 to 10 times. If the value of the variable MC is greater than “10”, it means that the call has been ringed 11 times or more. This is because it is judged that the importance of the call from the caller is higher as the number of ringing of the bell is higher, and the character information corresponding to it is displayed.
[0097]
Therefore, in the second embodiment, as shown in FIG. 20, the range of the number of ringing of the bell (value of the variable MC) and the character information to be displayed need to be stored in the memory 105 in association with each other. There is. The range of the ringing number of the bell (value of the variable MC) and the character information can be changed by the user's operation of the caller ID display adapter 100.
[0098]
As described above, according to the second embodiment, the ringing frequency of the bell is divided into a plurality of ranges, and the character information corresponding to each level is displayed, so that the importance of the call from the caller can be increased. The height can be visually appealed to the user of the caller ID display adapter 100.
[0099]
In the above example, the range of the number of ringing of the bell (value of the variable MC) is divided into three levels. However, the present invention is not limited to this, and the character information to be displayed is also shown in FIGS. It is not limited to the example shown.
[0100]
Incidentally, as in the second embodiment, an application example as described later can be considered by associating the range of the number of ringing of the bell (value of the variable MC) with the character information to be displayed.
[0101]
(Application example of the second embodiment)
Hereinafter, application examples of the second embodiment will be described with reference to FIGS.
[0102]
In this example, the character information to be displayed is determined in advance between the specific caller and the callee (user of the caller number display adapter 100), not the character information corresponding to the importance of the call from the caller. This is an application example in which character information representing the contents is displayed.
[0103]
In this case, as shown in FIG. 21, for example, the user of the caller ID display adapter 100 stores the range of the ringing number of the bell (value of the variable MC) and character information in the memory 105 in association with each other. It is necessary to. Although not shown, it is necessary to store the caller number information of a specific caller in the memory 105 as well.
[0104]
In FIG. 21, an incoming call with the bell ringing once or twice indicates that it will leave the company now, and an incoming call with the bell ringing only three or four times indicates that today's return will be delayed. As an example, a specific caller and a callee (user of the caller ID display adapter 100) negotiate with each other, and MC ≦ 2 and the character information “I will leave the company now” and Is stored in the memory 105 in association with the first pattern, and 2 <MC ≦ 4 and the character information “Today's return is late” is stored in the memory 105 in association with the second pattern. ing.
[0105]
In this example, when the main control unit 104 reads the number of ringing of the bell (value of the variable MC) and the caller ID information from the memory 105 and displays them on the display unit 107, the process shown in FIG. 22 is performed. Like that.
[0106]
That is, as shown in FIG. 22, the main control unit 104 determines whether or not the caller ID information to be displayed matches the caller ID information of the specific caller (step 2201), and the specific caller ID is determined. If it matches the caller ID information of the caller, it is determined whether the value of the variable MC to be displayed is larger than a predetermined threshold (in this example, “2”) (step 2202). If it is 2 ”or less, display according to the first pattern is performed (step 2203).
[0107]
If the value of the variable MC to be displayed is larger than “2” (step 2202), the value of the variable MC to be displayed is larger than a predetermined threshold (in this example, “5”). (Step 2204), if it is “5” or less, display according to the second pattern (step 2205), and if it is larger than “5”, the value of the variable MC is set. The message is displayed together with the caller ID information (step 2206).
[0108]
On the other hand, when the caller ID information to be displayed does not match the caller ID information of a specific caller (step 2201), main controller 104 displays the value of variable MC together with the caller ID information. (Step 2206).
[0109]
Here, a display example on the display unit 107 according to this example is shown in FIG.
[0110]
In FIG. 23, as shown in FIG. 12, caller number information and caller information (for example, name) registered in advance by the user of the caller number display adapter 100 are stored in the memory 105 in association with each other. An example is shown, and caller information (“Daddy mobile phone”) is displayed instead of caller number information.
[0111]
In this example, there is only one specific caller, but it is also possible to make different arrangements with a plurality of specific callers. In this case, the determined contents may be stored in the memory 105 for each of the caller number information of a plurality of specific callers.
[0112]
As described above, according to this example, a specific caller can transmit his / her intention without a callee (user of the caller number display adapter 100) responding.
[0113]
When the callee (user of the caller ID display adapter 100) responds and enters a call state, the caller is charged for the call. According to this example, the caller makes a call without answering. This is particularly effective when a caller makes a call from a mobile phone such as a mobile phone or a PHS terminal, which has a relatively high call charge.
[0114]
Therefore, it is possible to provide a telephone having a function for making a call to the caller ID display adapter 100 as in this example.
[0115]
Specifically, a function for accepting designation of a period for maintaining a ringing state (a period corresponding to a predetermined number of ringing bells) and a function for automatically disconnecting after maintaining the ringing state for the accepted period Can be added to the telephone.
[0116]
Further, in order to prevent the caller from forgetting the correspondence between the period during which the calling state is maintained and the character information displayed at the call destination, a function for storing both of them in association with each other is added. It may be.
[0117]
As a result, the caller can communicate his / her intention without making a mistake. Such a function is particularly effective when added to a mobile phone such as a mobile phone or a PHS terminal for the reasons described above.
[0118]
In the first embodiment and the second embodiment described above, the communication terminal is described as the caller ID display adapter 100 interposed between the fixed telephone and the analog network switch. Of course, it is also possible to realize a telephone with a caller ID display function accommodated in an analog network switch by combining the constituent elements shown in FIG.
[0119]
Therefore, it becomes possible to add the above-described functions to a telephone with a caller ID display function. Considering the case where such a telephone is a mobile telephone such as a mobile phone or a PHS terminal, the user Can communicate with each other without incurring a call charge.
[0120]
(Third embodiment)
In the first embodiment and the second embodiment described above, the communication terminal is described as the caller number display adapter 100 interposed between the fixed telephone and the analog network switch. It can also be realized as a caller number display adapter interposed between the digital network switch and a telephone with a caller number display function accommodated in the digital network switch.
[0121]
However, the basic sequence of the caller ID notification service in the digital network (ISDN network) is different from the basic sequence of the caller ID notification service in the analog network shown in FIG. 2 and FIG. The measuring method is different from the first embodiment and the second embodiment described above.
[0122]
Therefore, an embodiment in which the communication terminal is a telephone with a caller number display function accommodated in a digital network switch will be described below as a third embodiment with reference to FIGS.
[0123]
FIG. 24 is a block diagram showing a configuration of a telephone with a caller ID display function according to the third embodiment.
[0124]
In FIG. 24, 2400 is a telephone with caller number display function, 2401 is an L1 control unit, 2402 is an L2 / L3 control unit, 2403 is a main control unit, 2404 is a memory, 2405 is an operation unit, and 2406 is a display unit.
[0125]
The L1 control unit 2401 forms a communication path on the digital line with the digital network switch, and the L2 / L3 control unit 2402 exchanges call control signals with the digital network switch. It is.
[0126]
The main control unit 2403 executes the program stored in the memory 2404 to control the operation of the telephone 2400 with a caller ID display function as a whole, or to execute the operation according to the third embodiment. is there. That is, in the third embodiment, the main control unit 2403 measures the duration of the called state, and records the measured value in the memory 2404 in association with the caller ID information that arrives from the digital line when an incoming call is received. It is supposed to be.
[0127]
In the digital network, as will be described later, since the caller number information is included in the call setting signal, which is one of the call control signals, the main control unit 2403 has an L2 / L3 control unit. The caller ID information is detected by analyzing the call setup signal received by 2402.
[0128]
The operation unit 2405 is used by the user of the telephone 2400 with a caller ID display function to instruct reading of the recorded contents of the memory 2404, and for functioning as a telephone such as a handset or a push button. It also includes the necessary components.
[0129]
The display unit 2406 is used to display the recorded contents read from the memory 2404, and functions as a telephone such as a destination number dialed by the user of the telephone 2400 with a caller number display function. The contents to be displayed are also displayed.
[0130]
25 and 26 are sequence diagrams showing the basic sequence of the caller ID notification service in the digital network.
[0131]
FIG. 25 shows a basic sequence from when a caller responds to a call from the caller, transitioning to a busy state, and then disconnecting by the caller's call termination operation. 4 shows a basic sequence from when the caller is not answered to the call from, and until the call is abandoned by the caller's call termination operation.
[0132]
As shown in FIG. 25, when the caller performs a call origination (off-hook + dial) operation, a call setup signal (SETUP) arrives from the digital network switch to the telephone 2400 with caller number display function. When the telephone with number display function 2400 detects the reception of the call setting signal, it returns a ringing signal (ALERT) and means that it has shifted to the ringing state. Let The call setting signal includes caller ID information.
[0133]
When the user (called party) of the telephone 2400 with caller number display function that rings the ring performs a response (off-hook) operation, the called state of the telephone 2400 with caller number display function is canceled and the caller number display function is provided. The telephone 2400 stops outputting the ring tone to stop the ringing of the bell, and transmits a response signal (CONN) to the digital network switch.
[0134]
Subsequently, a response confirmation signal (CONNACK) arrives from the digital network exchange that has detected the reception of the response signal to the telephone 2400 with caller number display function, whereby the digital network switch and the telephone with caller number display function are received. A call path is formed on the digital line between the caller and the caller 2400, and the caller and the callee shift to a busy state.
[0135]
Now, when the caller performs an end-of-call (on-hook) operation in a call state, a disconnection signal (DISC) arrives from the digital network switch to the telephone 2400 with caller number display function. When the function-equipped telephone 2400 detects reception of the disconnection signal, it outputs a busy tone (BT).
[0136]
When the user (called party) of the telephone number 2400 with caller number display function who has heard the busy tone performs an on-hook operation, the telephone number 2400 with caller number display function sends a release signal ( REL).
[0137]
Subsequently, a release completion signal (RELCOMP) is received from the digital network switch that has detected the reception of the release signal to the telephone 2400 with caller number display function, whereby the digital network switch and the telephone with caller number display function are received. The communication path formed on the digital line with 2400 is disconnected.
[0138]
As shown in FIG. 26, the sequence from when the caller performs a call operation until the caller number display function-equipped telephone 2400 rings the bell is the same as that shown in FIG.
[0139]
Here, since the user (caller) of the telephone 2400 with caller ID display function whose ringing bell does not perform a response (off-hook) operation and is not answered, the caller ends the call to abandon the call. (On-hook) operation is being performed.
[0140]
When the caller performs the call termination operation, a disconnection signal (DISC) arrives from the digital network switch to the telephone 2400 with caller number display function. Therefore, the telephone 2400 with caller number display function receives the disconnection signal. Is detected, the ringing state of the telephone 2400 with caller ID display function is canceled, the ringing tone is stopped and the ringing of the bell is stopped, and the release signal (REL) is returned to the digital network exchange. .
[0141]
Subsequently, a release completion signal (RELCOMP) arrives from the digital network switch that has detected reception of the release signal to the telephone 2400 with a caller ID display function.
[0142]
The basic sequence shown in FIGS. 25 and 26 is the same as the conventional basic sequence.
[0143]
In the third embodiment, the telephone 2400 with a caller ID display function measures the duration of the called state. The duration of the called state is the basic sequence shown in FIG. Corresponds to a period from the time when the telephone 2400 with caller number display function transmits a call signal to the time when a response signal is transmitted. In the basic sequence shown in FIG. This corresponds to a period from the time when the telephone 2400 transmits the calling signal to the time when reception of the disconnection signal is detected.
[0144]
FIG. 27 and FIG. 28 are diagrams showing a process in which the telephone 2400 with caller number display function measures the duration of the called state.
[0145]
As shown in FIG. 27, in telephone set 2400 with a caller ID display function, main controller 2403 detects that L2 / L3 controller 2402 has received a call setup signal in an empty state (step 2701). The ringing tone is output to ring the bell (step 2702), and the called state measurement timer is activated (step 2703). Then, the main control unit 2403 requests the L2 / L3 control unit 2402 to return a calling signal to the digital network switch (step 2704), and the caller ID information included in the call setting signal is stored in the memory 2404. Is recorded (step 2705), and then the state is called.
[0146]
As shown in FIG. 28, in the telephone 2400 with caller number display function, the main control unit 2403 detects that the user of the telephone 2400 with caller number display function has made a response operation in the called state. Then (step 2801), the ringtone output is stopped to stop the ringing of the bell (step 2802), and the called state measurement timer is stopped (step 2803).
[0147]
Since the measured value at the time when the called state measurement timer is stopped corresponds to the duration of the called state, the main control unit 2403 stores the measured value in step 2705 of FIG. It is recorded in the memory 2404 in association with the number information (step 2804).
[0148]
Then, the main control unit 2403 requests the L2 / L3 control unit 2402 to transmit a response signal to the digital network switch (step 2805), and confirms that the L2 / L3 control unit 2402 has received the response confirmation signal. When it is detected (step 2806), it shifts to a busy state.
[0149]
On the other hand, as shown in FIG. 28, in telephone set 2400 with a caller ID display function, main controller 2403 detects that L2 / L3 controller 2402 has received a disconnection signal in the called state (step 2811). The ringing tone output is stopped to stop the ringing of the bell (step 2812), and the called state measurement timer is stopped (step 2813).
[0150]
Since the measured value at the time when the called state measurement timer is stopped corresponds to the duration of the called state, the main control unit 2403 stores the measured value in step 2705 of FIG. It is recorded in the memory 2404 in association with the number information (step 2814).
[0151]
Then, the main control unit 2403 requests the L2 / L3 control unit 2402 to transmit a release signal to the digital network switch (step 2815), and confirms that the L2 / L3 control unit 2402 has received the release completion signal. When it is detected (step 2816), it shifts to an empty state.
[0152]
In the third embodiment, the main control unit 2403 records the measurement value and the caller ID information in the memory 2404 in association with each other as in the first embodiment described above. However, the main control unit 2403 records the measured value of the called state measurement timer instead of the bell ringing frequency 1004 in FIG. 10, and the incoming call date and time 1002 in FIG. 10 activates the called state measurement timer. Date and time.
[0153]
Also in the third embodiment, as in the first embodiment described above, the latest recorded content of the recorded content recorded in the memory 2404 is read from the memory 2404 and displayed on the display unit 2506. The Rukoto. However, instead of the display content 1104 in FIG. 11, display content (for example, “xx seconds”) indicating the measurement value of the called state measurement timer is displayed.
[0154]
In the third embodiment, since the basic sequence in the digital network is used for explanation, when the caller abandons the call, a disconnection signal is received, but the called state is released. There is a possibility that a signal to be disconnected other than the disconnection signal (for example, a release signal or a release completion signal) will arrive as an event other than the response operation. However, since any signal is a signal to be cut, it can be dealt with in the same way as when a cut signal is received.
[0155]
As a result, even if the user of the telephone 2400 with caller number display function does not answer the incoming call, he / she can call the caller by viewing the measured value of the called state measurement timer displayed on the display unit 2506 later. You can feel the importance of calling from and take actions such as calling back. Specifically, as the measured value of the called state measurement timer is larger, it means that the caller has called for a longer period, so it can be determined that the call is an important call.
[0156]
Also, from the standpoint of the caller, in particular, when the callee is not answered, the user's intention (the importance of the call) can be conveyed without incurring a call charge.
[0157]
Therefore, according to the third embodiment, as in the first embodiment described above, the judgment material for measuring the importance of the call from the caller can be given to the user of the telephone 2400 with caller number display function. As a result, user benefits can be realized.
[0158]
In the third embodiment, as in the first embodiment described above, as shown in FIG. 12, caller number information 1201 registered in advance by the user of the telephone 2400 with caller number display function and If caller information (for example, name) 1202 is stored in the memory 105 in association with each other, in step 2705 of FIG. 27, the main control unit 2403 causes the caller included in the received call setting signal. When the same sender number information 1201 as the number information is stored, the corresponding sender information 1202 may be recorded in the memory 2403 instead of the sender number information.
[0159]
Also in the third embodiment, as in the first embodiment described above, when there is no empty entry at the time of recording, the main control unit 2403 selects the entry with the smallest measured value of the called state measurement timer. If the measured value is less than or equal to the measured value to be recorded, the searched entry can be deleted.
[0160]
Also in the third embodiment, as in the first embodiment described above, the main control unit 2403 performs recording when the measurement value of the called state measurement timer is equal to or less than a predetermined threshold value. By making such a configuration, only entries for incoming calls with a high importance level of the call from the caller are recorded, and the memory 2404 can be used effectively.
[0161]
In addition, when only the entry about the incoming call with high importance of the call from the caller is recorded, when the caller makes a call from a mobile phone such as a mobile phone or a PHS terminal, The call may be interrupted against the intention of the caller. Therefore, when the caller number information represents the number of a mobile phone such as a mobile phone or a PHS terminal, the main control unit 2403, even if the measurement value of the called state measurement timer is less than the threshold value, Recording may be performed.
[0162]
In addition, when only an entry for an incoming call having a high importance level of a call from the caller is recorded, caller number information registered in advance by the user of the telephone 2400 with caller number display function is stored in the memory 2404. By doing so, the main control unit 2403, for the same caller number information as the caller number information stored in the memory 2404, even if the measurement value of the called state measurement timer is below the threshold, Recording may be performed.
[0163]
Also in the third embodiment, as in the first embodiment described above, when the recorded content recorded in the memory 2404 is read and displayed on the display unit 2406, it corresponds to the measurement value of the called state measurement timer. The display mode may be changed.
[0164]
Also in the third embodiment, as in the first embodiment described above, the main control unit 2403 can be used when the caller performs a response operation and when the caller performs a call end operation. In either case, the measured value of the called state measurement timer and the caller ID information are stored in association with each other in the memory 2404. However, when the callee performs a response operation, the caller ID display function Since the user of the attached telephone 2400 is considered to have confirmed the display content of the display unit 2406, the content recorded in the memory 2404 may be deleted at the end of the call or at the next recording time. In order to delete at the next recording, it is necessary to record that there is a response.
[0165]
In addition, when the telephone 2400 with caller number display function has an answering machine function, the answering machine function may respond even if the callee does not answer, and the caller records the message. Therefore, when the answering machine function responds, it is preferable that the main control unit 2403 not delete the contents recorded in the memory 2404.
[0166]
Further, in the third embodiment, similarly to the second embodiment described above, processing is performed when the measured value of the called state measurement timer recorded in the memory 2404 is displayed on the display unit 2406. It may be.
[0167]
By the way, in the communication terminal which records and displays caller ID information like the caller ID display adapter 100 and the caller ID display function-equipped telephone 2400, the first to third embodiments described above are as follows. The duration of the called state is used, but the duration of the called state at the communication terminal is not only a measure of the importance of the call from the caller, but also a criterion for providing various services. It is also possible to use it.
[0168]
Specifically, a communication terminal configured to perform a predetermined operation when the duration of the called state exceeds a predetermined threshold value can be realized as an application example. Here, the predetermined operation may be various operations such as a pager calling operation and a call back operation.
[0169]
(Application example of the third embodiment)
Accordingly, a communication terminal in which the duration of the called state is used as a determination material for providing a service will be described below with reference to FIGS.
[0170]
In this example, it is assumed that the communication terminal is a call center device accommodated in a digital network switch. Therefore, this example is an application example of the above-described third embodiment.
[0171]
FIG. 29 is a block diagram showing a configuration of a call center device according to the present example.
[0172]
In FIG. 29, 2900 is a call center device, 2901 is an L1 control unit, 2902 is an L2 / L3 control unit, 2903 is a voice response control unit, 2904 is a main control unit, and 2905 is a memory.
[0173]
The L1 control unit 2901 forms a communication path on the digital line with the digital network switch, and the L2 / L3 control unit 2902 exchanges call control signals with the digital network switch. It is.
[0174]
The voice response control unit 2903 sends a guidance message or the like.
[0175]
Further, the main control unit 2904 executes the program stored in the memory 2905, thereby controlling the operation of the entire call center device 2900 or executing the operation according to this example. That is, in this example, the main control unit 2904 measures the duration of the called state and performs either a callback operation or an automatic response operation according to the measured value.
[0176]
30 and 31 are sequence diagrams showing an operation sequence of the call center device 2900. FIG. 30 shows a sequence of the callback operation, and FIG. 31 shows a sequence of the automatic response operation.
[0177]
When call center apparatus 2900 is disconnected within a predetermined period after receiving an incoming call, that is, when the duration of the called state is within a predetermined period, call center apparatus 2900 returns the caller to the caller. After performing a callback operation to make a call and accepting an incoming call, if it is not disconnected even after a predetermined period of time, that is, if the duration of the called state exceeds the predetermined period An automatic response operation for automatically responding to the caller is performed.
[0178]
First, the callback operation will be described. As shown in FIG. 30, when the caller performs a call origination (off-hook + dial) operation, a call setup signal (SETUP) arrives from the digital network switch to the call center apparatus 2900. Therefore, when the call center apparatus 2900 detects the reception of the call setting signal, it returns a call signal (ALERT) and means that the call center apparatus 2900 has shifted to the called state, and thus activates the called state measurement timer. The called state measurement timer times out when it reaches a predetermined threshold.
[0179]
Here, the caller performs an on-hook operation to abandon the call before the called state measurement timer times out.
[0180]
When the caller performs the call termination operation, a disconnect signal (DISC) arrives from the digital network switch to the call center device 2900. When the call center device 2900 detects reception of the disconnect signal, the call center device 2900 is called. The state is released, the called state measurement timer is stopped, and a release signal (REL) is returned to the digital network switch.
[0181]
Subsequently, since a release completion signal (RELCOMP) arrives from the digital network switch that has detected reception of the release signal to the call center device 2900, when the call center device 2900 detects reception of the release completion signal, In order to make a return call, a call setup signal (SETUP) is transmitted to the digital network exchange. Note that caller number information of a caller necessary for making a return call is included in a call setting signal received when an incoming call from the caller is accepted.
[0182]
Subsequently, since a call setup acceptance signal (CALLPROC) and a paging signal (ALERT) arrive from the digital network switch that has detected the reception of the call setup signal to the call center device 2900, the call setup acceptance signal and the paging signal are received. The detected call center device 2900 waits for a response from the previous caller.
[0183]
When a previous caller performs a response (off-hook) operation for an incoming call by return call, a response signal (CONN) arrives from the digital network exchange to the call center device 2900. Therefore, the call center device 2900 receives the response signal. When the reception is detected, a response confirmation signal (CONNACK) is returned to the digital network exchange, and information such as guidance is provided.
[0184]
Next, the automatic response operation will be described. As shown in FIG. 31, the sequence from when the caller performs a call operation until the called state measurement timer is activated is the same as that shown in FIG.
[0185]
Here, even if the caller state measurement timer times out, the caller continues calling without abandoning the call.
[0186]
Therefore, when the called state measurement timer times out, the call center device 2900 transmits a response signal (CONN) to the digital network switch.
[0187]
Subsequently, since a response confirmation signal (CONACK) arrives from the digital network switch that has detected reception of the response signal to the call center device 2900, the call center device 2900 transmits guidance when detecting reception of the response confirmation signal. Provide information such as.
[0188]
32 to 35 are diagrams showing processing of the call center device 2900.
[0189]
As shown in FIG. 32, in the call center device 2900, when the main control unit 2904 detects that the L2 / L3 control unit 2902 has received a call setting signal in an empty state (step 3201), a called state measurement timer (Step 3202), the L2 / L3 control unit 2902 is requested to return a calling signal to the digital network switch (step 3203), and the caller ID information included in the call setting signal is stored in the memory. After temporarily recording in 2404 (step 3204), the process proceeds to the called state.
[0190]
Subsequently, as shown in FIG. 33, in the call center device 2900, when the main control unit 2904 detects that the L2 / L3 control unit 2902 receives a disconnection signal in the called state (step 3301), the caller Means that the call is abandoned before the called state measurement timer times out, so the called state measurement timer is stopped (step 3302) and a release signal is returned to the digital network switch. Request is made to the L2 / L3 control unit 2902 (step 3303). Then, the main control unit 2904 generates a callback request event for itself to make a return call to the caller (step 3304), and then shifts to an empty state.
[0191]
Therefore, as shown in FIG. 32, in the call center device 2900, when the main control unit 2904 detects the occurrence of a callback request event in an empty state (step 3211), the main control unit 2904 activates the non-response measurement timer (step 3211). 3212), the L2 / L3 control unit 2902 is requested to transmit a call setting signal to the digital network switch (step 3213), and the state shifts to the call origination / response state.
[0192]
In step 3213, the main control unit 2904 transmits a call setting signal to call back to the previous caller using the caller number information temporarily recorded in step 3204. It is what is requested. Further, the non-response measurement timer operated in step 3212 is used as a judgment material for automatically disconnecting when there is no response to the return transmission, and when it reaches a predetermined threshold value, it times out. It has become.
[0193]
Subsequently, as shown in FIG. 34, in the call center device 2900, when the main control unit 2904 detects that the L2 / L3 control unit 2902 has received the response signal in the call / response state (step 3411), the call control apparatus 2900 returns. This means that there has been a response to the transmission, so the non-response measurement timer is stopped (step 3412), and the L2 / L3 control unit 2902 is requested to return a response confirmation signal to the digital network switch. (Step 3413). Then, the main control unit 2904 requests the voice response control unit 2903 to start the voice response process (step 3414), and then shifts to a busy state.
[0194]
In addition, when the non-response measurement timer times out in the call / response state (step 3431), the main control unit 2904 means that there is no response to the return call even after a predetermined period has elapsed. After requesting the L2 / L3 control unit 2902 to transmit a disconnection signal to the digital network switch (step 3432), the process shifts to an empty state.
[0195]
When the main control unit 2904 detects that the L2 / L3 control unit 2902 has received a disconnection signal in the call / response state (step 3401), the main control unit 2904 may be connected to the digital network because the return destination is busy. Since this means that the switch is disconnected, the non-response measurement timer is stopped (step 3402), and the L2 / L3 control unit 2902 is requested to return a release signal to the digital network switch. (Step 3403), transition to an empty state.
[0196]
On the other hand, as shown in FIG. 33, in the call center device 2900, when the called state measurement timer times out in the called state and the called state measurement timer times out (step 3311), the caller waits for a predetermined period. This means that the call has not been abandoned, so that the L2 / L3 control unit 2902 is requested to send a response signal to the digital network exchange in order to automatically answer the caller. (Step 3312), the call / response state is entered.
[0197]
Subsequently, as shown in FIG. 34, in the call center device 2900, when the main control unit 2904 detects that the L2 / L3 control unit 2902 has received the response confirmation signal in the calling / response state (step 3421), After requesting the voice response control unit 2903 to start the voice response process (step 3422), the process shifts to a busy state.
[0198]
As shown in FIG. 35, in the call center device 2900, when the main control unit 2904 detects that the voice response control unit 2903 has finished the voice response process in a busy state (step 3511), it disconnects from itself. In order to do this, the L2 / L3 control unit 2902 is requested to transmit a disconnection signal to the digital network switch (step 3512), and then it shifts to an empty state.
[0199]
As shown in FIG. 35, in the call center device 2900, when the main control unit 2904 detects that the L2 / L3 control unit 2902 has received a disconnection signal in a call state (step 3501), the voice response process This means that the call was disconnected from the other party during execution of the call, so the voice response control unit 2903 is requested to stop the voice response process (step 3502), and a release signal is returned to the digital network switch. Thus, after making a request to the L2 / L3 control unit 2902 (step 3503), it shifts to an empty state.
[0200]
As described above, according to the present example, when a caller abandons a call within a predetermined period and then hangs up after making a call to the call center apparatus 2900, the call center apparatus 2900 makes a return call. Therefore, the information providing service of the call center device 2900 can be received free of charge, and if the call is not abandoned even after a predetermined period of time has passed after being transmitted to the call center device 2900 Since the call center apparatus 2900 automatically responds, the information providing service of the call center apparatus 2900 can be received. Therefore, according to this example, it is possible to select a call charge payee on the caller side.
[0201]
