Description

  The present invention relates to a communication system for controlling communication between a first communication terminal and a second communication terminal.

  A communication system is known that includes a first communication terminal, a second communication terminal, and a call control device that is communicably connected to each of the first communication terminal and the second communication terminal. In this communication system, when a user (first user) using a first communication terminal performs an operation to make a call to a user (second user) using a second communication terminal, the first communication is performed. The terminal transmits communication destination specifying information for specifying the second communication terminal as the communication terminal of the communication destination to the call control device.

  When the call control device receives the communication destination specifying information from the first communication terminal, the call control device calls the second communication terminal to enable communication between the first communication terminal and the second communication terminal. A call signal is transmitted to the second communication terminal.

  As one of this type of communication system, in the communication system described in Patent Document 1, the second communication terminal transmits notification information to the call control device. The notification information is information indicating the position of the user (second user) who uses the second communication terminal. The call control device is located from the information indicating that the notification information is away (the second user is in a position where the second communication terminal cannot be used) (the position where the second user can use the second communication terminal). The first communication terminal and the second communication terminal are called, and the two are connected so as to enable communication between the two.

  Hereinafter, embodiments of a communication system, a call control device, a call control program, and a call control method according to the present invention will be described with reference to FIGS.

<Embodiment>
As shown in FIG. 1, the communication system 1 according to the embodiment includes a first telephone terminal (first communication terminal) 2, a second telephone terminal (second communication terminal) 3, and a call control device. 4 and an RFID (Radio Frequency Identification) reader (reading device) 5.

  The first telephone terminal 2 includes a handset and a plurality of buttons including dial buttons (button switches) “0” to “9”. The second telephone terminal 3 has the same configuration as the first telephone terminal 2.

  The call control device 4 is communicably connected to each of the first telephone terminal 2 and the second telephone terminal 3. The call control device 4 includes a CPU (not shown) and a storage device (memory, hard disk device (HDD), etc.) constituting storage means. The call control device 4 realizes various functions including functions described later by the CPU executing a program stored in the storage device. Further, the call control device 4 may have a circuit that performs the same processing as the program.

  The RFID reader 5 is a device that reads information held (stored) in an RFID tag (identification information holding body) 6 via an electromagnetic wave (by wireless communication at a short distance (for example, several meters)). The RFID reader 5 includes a storage device (memory in this example) (not shown). In the storage device of the RFID reader 5, user identification information for identifying the user UB that uses the second telephone terminal 3, terminal identification information for identifying the second telephone terminal 3 (in this example, a telephone number), Is stored in advance.

  The RFID tag 6 holds user identification information for identifying the user UB. The RFID tag 6 is held by the user UB. In this example, the RFID tag 6 is formed integrally with an employee card carried by the user UB.

The RFID reader 5 is attached to the RFID tag 6 when the position of the RFID tag 6 is an area including the second telephone terminal 3 and an area in the vicinity of the second telephone terminal 3 (terminal use area). It is held in the RFID tag 6 so that the user identification information held can be read out, and the position of the RFID tag 6 is not a position in the terminal use area (a position outside the terminal use area). It is set in advance so that the user identification information cannot be read. The RFID reader 5 is connected to the call control device 4 so as to be communicable.
Note that the RFID reader 5 and the RFID tag 6 constitute user position detecting means.

  FIG. 2 is a block diagram showing functions of the communication system 1 configured as described above. This function is realized by the CPU of the call control device 4 executing a program represented by flowcharts shown in FIGS. 3 and 5 to be described later.

The function of the RFID reader 5 includes a user position detection unit (user position detection means) 11 and a user position information transmission unit 12.
The user position detection unit 11 reads the user identification information held in the RFID tag existing in the terminal use area every time a preset detection time elapses.

  When the read user identification information matches the user identification information stored in the storage device of the RFID reader 5, the user position detection unit 11 determines that the position of the user UB that uses the second telephone terminal 3 is the terminal. User position information indicating that the position is within the use area (“attended”) is generated.

  On the other hand, when the user identification information that has been read does not match the user identification information stored in the storage device, and when none of the user identification information has been read, the user position detection unit 11 User position information indicating that the position of the user UB using the telephone terminal 3 is not a position in the terminal use area (“seating”) is generated.

  That is, it can be said that the user position detection unit 11 detects whether or not the position of the user UB who uses the second telephone terminal 3 is a position in the terminal use area.

  The user position information transmission unit 12 transmits the user position information generated by the user position detection unit 11 and the terminal identification information stored in the storage device of the RFID reader 5 to the call control device 4.

  The function of the call control device 4 includes a user location information receiving unit (user location information receiving means, user location information receiving step) 21, a user location information storage unit 22, a call control unit (call control means) 23, and a call. An information storage unit (calling information storage means) 24.

  The user position information receiving unit 21 receives (accepts) user position information and terminal identification information from the user position information transmitting unit 12.

  The user location information storage unit 22 stores the per-terminal user location information in which the user location information and the terminal identification information received by the user location information reception unit 21 are associated with each other in the storage device of the call control device 4. At this time, the user location information storage unit 22 is configured to store the user location information for each terminal including the same terminal identification information as the terminal identification information included in the user location information for each terminal to be newly stored in the storage device. Stores the new per-terminal user position information after deleting the per-terminal user position information.

The call control unit 23 includes a call information receiving unit 23a and a selection information receiving unit 23b.
The call information receiving unit 23 a receives call information from the first telephone terminal (communication source terminal) 2. Here, the call information includes communication source identification information and communication destination identification information.

  The communication source identification information is information for specifying a telephone terminal (communication source terminal). The call information receiving unit 23a receives the call signal from the telephone terminal, thereby acquiring information specifying the telephone terminal that has transmitted the call signal as communication source specifying information.

  The communication destination specifying information is information (in this example, a telephone number) that specifies a telephone terminal (communication destination terminal). The call information receiving unit 23a receives (receives) information represented by the communication destination selection signal as communication destination specifying information by receiving the communication destination selection signal from the telephone terminal.

  The call control unit 23 is the same as the communication destination specifying information included in the call information received by the call information receiving unit 23a among the user location information for each terminal stored in the storage device of the call control device 4. Terminal-specific user location information including terminal identification information is acquired. When the user location information included in the acquired user location information for each terminal represents “present”, the call control unit 23 proceeds to the second telephone terminal (communication destination terminal) 3 specified by the communication destination specification information. A call signal for calling the communication destination terminal 3 is transmitted.

  When receiving the call signal, the communication destination terminal 3 generates a ringing tone through a speaker (not shown). In this state, the communication destination terminal 3 transmits a response signal to the call control device 4 by lifting the handset by the user UB.

When receiving a response signal from the communication destination terminal 3, the call control unit 23 establishes communication between the communication source terminal 2 and the communication destination terminal 3 (communication between the communication source terminal 2 and the communication destination terminal 3 is established). enable).
Thereby, a call is performed between the user UA using the communication source terminal 2 and the user UB using the communication destination terminal 3.

  On the other hand, when the user location information included in the acquired user location information for each terminal represents “seating”, the call control unit 23 displays the call information received by the call information receiving unit 23a as the call information storage unit 24. Send to. Furthermore, the call control unit 23 establishes communication between the communication source terminal 2 and the call control device 4. Then, the call control unit 23 notifies the user UA that uses the communication source terminal 2 of a message indicating that the user UB that uses the communication destination terminal 3 is absent (plays back a voice that represents the message). That is, in this case, the call control unit 23 does not transmit a call signal for calling the communication destination terminal 3 to the communication destination terminal 3.

  When receiving the call information from the call control unit 23, the call information storage unit 24 stores the received call information in the storage device of the call control device 4.

  In addition, the call control unit 23 changes the user position information included in the user position information for each terminal stored in the storage device of the call control device 4 from information indicating “seating” to information indicating “seating”. If it does, callback processing is performed.

  The callback process calls the communication source terminal 2 and causes the user UA that uses the communication source terminal 2 to select whether or not to call the communication destination terminal 3, and performs communication when the call to the communication destination terminal 3 is selected. This is a process for calling the destination terminal 3.

  Specifically, the call control unit 23 uses the same communication destination as the terminal identification information included in the per-terminal user position information including the user position information changed from the information indicating “seating” to the information indicating “present”. The call information including the specific information is the call information stored in the storage device of the call control device 4 by the call information storage unit 24 and is not associated with the call prohibition information described later. Get from.

  The call control unit 23 ends the callback process when the call information is not acquired. On the other hand, when the call information is acquired, the call control unit 23 transmits a call signal for calling the communication source terminal 2 specified by the communication source specifying information included in the acquired call information to the communication source terminal 2. .

  When receiving the call signal, the communication source terminal 2 generates a ringing tone via a speaker (not shown). In this state, the communication source terminal 2 transmits a response signal to the call control device 4 by lifting the handset by the user UA using the communication source terminal 2.

  When receiving a response signal from the communication source terminal 2, the call control unit 23 establishes communication between the communication source terminal 2 and the call control device 4. Then, the call control unit 23 sends a message prompting to input selection information for selecting any one of the first process, the second process, and the third process to the communication source terminal 2. The user UA who uses is notified.

  Here, the first process is a process for establishing communication with the communication destination terminal 3. The second process is a process for postponing the start of communication with the communication destination terminal 3. Further, the third process is a process for canceling the request for communication with the communication destination terminal 3.

Then, the selection information receiving unit 23b receives (accepts) selection information from the communication source terminal 2.
Here, the selection information is communication request information, communication postponement information, or request cancellation information. The communication request information is information for requesting communication with the communication destination terminal 3. The communication postponement information is information that instructs to postpone the start of communication with the communication destination terminal 3. The request cancellation information is information that instructs to cancel a request for communication with the communication destination terminal 3.

When the selection information received by the selection information receiving unit 23b is communication request information, the call control unit 23 transmits a call signal for calling the communication destination terminal 3 to the communication destination terminal 3. When receiving the call signal, the communication destination terminal 3 generates a ringing tone through a speaker (not shown). In this state, the communication destination terminal 3 transmits a response signal to the call control device 4 by lifting the handset by the user UB. When receiving the response signal from the communication destination terminal 3, the call control unit 23 establishes communication between the communication source terminal 2 and the communication destination terminal 3. Thereby, a call is performed between the user UA using the communication source terminal 2 and the user UB using the communication destination terminal 3.
Further, the call control unit 23 deletes the acquired call information from the storage device of the call control device 4.

  On the other hand, when the selection information received by the selection information receiving unit 23b is communication postponement information, the call control unit 23 associates the call information with the acquired call information without transmitting a call signal to the communication destination terminal 3. The call prohibition information is stored in the storage device of the call control device 4. The call prohibition information is information representing the date and time (future) after a preset delay time (for example, 3 hours) from the date and time when the selection information is received. Note that the call control unit 23 deletes, from the storage device, the call prohibition information that represents the date and time prior to the current time among the call prohibition information stored in the storage device.

  Further, when the selection information received by the selection information receiving unit 23b is request cancellation information, the call control unit 23 transmits the acquired call information to the call control device without transmitting a call signal to the communication destination terminal 3. 4 from the storage device.

The function of the communication source terminal 2 includes a call information transmission unit 31, a selection information input unit 32, and a selection information transmission unit 33.
The call information transmitting unit 31 transmits a call signal to the call control device 4 when the handset is lifted by the user UA. The call information transmitting unit 31 transmits a communication destination selection signal to the call control device 4 when a dial button is pressed by the user UA after transmitting the call signal.

  The selection information input unit 32 receives the selection information input by the user UA when the user UA presses a dial button corresponding to each of the communication request information, the communication postponement information, and the request cancellation information. The selection information transmission unit 33 transmits the selection information received by the selection information input unit 32 to the call control device 4.

Next, the operation of the communication system 1 described above will be specifically described.
Now, the description will be continued assuming that the position of the user UB that uses the communication destination terminal 3 is a position in the terminal use area.

In this case, the RFID reader 5 performs call control on user position information indicating that the position of the user UB is a position in the terminal use area (“attended”) and terminal identification information for identifying the communication destination terminal 3. Transmit to device 4.
Thereby, the call control device 4 stores the user location information indicating “attended” and the terminal identification information for identifying the communication destination terminal 3 in the storage device of the call control device 4. Remember.

  On the other hand, the CPU of the call control device 4 executes the call control program at the time of call shown by the flowchart in FIG. 3 only once when the call control device 4 is activated. Note that the execution of the processing of the program in FIG. 3 corresponds to the achievement of part of the functions of the call control process and the call control means.

Specifically, the CPU waits until call information is received (step 305).
Now, description will be continued for the case where the user UA using the communication source terminal 2 wishes to talk to the user UB.

  In this case, the user UA lifts the handset of the communication source terminal 2 and inputs communication destination specifying information (phone number of the communication destination terminal 3) for specifying the communication destination terminal 3 by pressing a dial button. Thereby, the communication source terminal 2 transmits the call information to the call control device 4 by transmitting the call signal and the communication destination selection signal indicating the communication destination specifying information.

  Therefore, the CPU of the call control device 4 determines “Yes” and proceeds to step 310, in which the received call information is included in the received user location information stored in the storage device of the call control device 4. Per-terminal user position information including the same terminal identification information as the included communication destination specifying information is acquired.

Then, the CPU determines whether or not the user position information included in the acquired per-terminal user position information indicates “attended” (the position of the user UB is a position in the terminal use area).
If the above assumption is followed, terminal-specific user location information in which terminal identification information for identifying the communication destination terminal 3 is associated with user location information indicating “attended” is stored in the storage device of the call control device 4. Yes.

Accordingly, the CPU determines “Yes”, proceeds to step 315, and transmits a call signal for calling the communication destination terminal 3 to the communication destination terminal 3. Next, the CPU performs a call process between the communication source terminal 2 and the communication destination terminal 3 (step 320). That is, the CPU establishes communication between the communication source terminal 2 and the communication destination terminal 3 when receiving a response signal from the communication destination terminal 3 (communication between the communication source terminal 2 and the communication destination terminal 3 is performed). enable).
Thereby, a telephone call is performed between the user UA and the user UB.

  Next, the CPU returns to step 305 and repeatedly executes the processing of step 305 to step 330.

  Next, a case will be described in which the user UA using the communication source terminal 2 wishes to talk to the user UB in a state where the position of the user UB using the communication destination terminal 3 is not a position in the terminal use area.

In this case, the RFID reader 5 receives the user position information indicating that the position of the user UB is not a position in the terminal use area (“seating”) and terminal identification information for identifying the communication destination terminal 3. 4 (step D41 in FIG. 4).
As a result, the call control device 4 stores in the storage device of the call control device 4 the per-terminal user location information in which the user location information indicating “seating” and the terminal identification information for identifying the communication destination terminal 3 are associated. Store (step B41 in FIG. 4).

  When the CPU of the call control device 4 proceeds to step 310 in FIG. 3, the CPU determines “No”, proceeds to step 325, and performs a user absence message notification process. That is, the CPU establishes communication between the communication source terminal 2 and the call control device 4. Then, the CPU notifies the user UA that uses the communication source terminal 2 of a message (user absence message) indicating that the user UB that uses the communication destination terminal 3 is absent (reproduces the voice that represents the message, 4 step B42).

  According to this, when the position of the user UB is outside the terminal use area (the user UB is in a position where the communication destination terminal 3 cannot be used), it is possible to prevent the communication destination terminal 3 from being called unnecessarily. it can. Furthermore, it is possible to make the user UA recognize that the position of the user UB is outside the terminal use area. As a result, the convenience of the user UA can be improved.

Next, the CPU stores the call information received in step 305 in the storage device of the call control device 4 (step 330 in FIG. 3 and step B43 in FIG. 4). Thereafter, the CPU returns to step 305 and repeatedly executes the processing of step 305 to step 330.
The processing in step 330 corresponds to the call information storage processing step and the call information storage processing means.

  On the other hand, the CPU of the call control device 4 is configured to execute the user position change call control program shown by the flowchart in FIG. 5 only once when the call control device 4 is activated. The execution of the processing of the program in FIG. 5 corresponds to the achievement of part of the functions of the call control process and the call control means.

Specifically, the CPU waits until user position information is received (step 505).
Now, a state is assumed in which call information including communication source specifying information for specifying the communication source terminal 2 and communication destination specifying information for specifying the communication destination terminal 3 is stored in the storage device of the call control device 4. In this state, a case where the user UB moves from a position outside the terminal use area to a position within the terminal use area will be described.

  In this case, the RFID reader 5 performs call control on user position information indicating that the position of the user UB is a position in the terminal use area (“attended”) and terminal identification information for identifying the communication destination terminal 3. The data is transmitted to the device 4 (step D61 in FIG. 6).

  Thereby, the call control device 4 stores the user location information indicating “attended” and the terminal identification information for identifying the communication destination terminal 3 in the storage device of the call control device 4. This is stored (step B61 in FIG. 6).

  Further, the CPU of the call control device 4 determines “Yes” in step 505 in FIG. 5 and proceeds to step 510, where the position of the user UB has changed from a position outside the terminal use area to a position in the terminal use area. It is determined whether or not.

  In this state, the user position information stored in the storage device of the call control device 4 has changed from information representing “seated” to information representing “present”. Therefore, the CPU determines “Yes” and proceeds to step 515.

  Next, the CPU stores the call information including the communication destination specifying information for specifying the communication destination terminal 3 and not associated with the call prohibition information in the storage device of the call control device 4. It is determined whether or not.

In this state, the CPU determines “Yes” and proceeds to step 520.
If “No” is determined in step 510 or step 515, the CPU returns to step 505.

  In step 520, the CPU specifies the same communication destination as the terminal identification information included in the user position information for each terminal including the user position information changed from the information indicating “seating” to the information indicating “present”. Call information including information (here, communication destination specifying information for specifying the communication destination terminal 3) is call information stored in the storage device of the call control device 4 and associated with call prohibition information. Get out of no call information. Further, the CPU transmits a call signal for calling the communication source terminal 2 specified by the communication source specification information included in the acquired call information to the communication source terminal 2 (step B62 in FIG. 6).

  Next, the CPU performs a selection information input message notification process between the communication source terminal 2 and the call control device 4 (step 525). That is, the CPU establishes communication between the communication source terminal 2 and the call control device 4 when a response signal is received from the communication source terminal 2. Then, the CPU notifies a message (selection information input message) prompting to input the selection information (reproducing voice representing the message, step B63 in FIG. 6).

Next, the CPU waits until selection information is received (step 530).
First, a case where the user UA desires to talk to the user UB at this time will be described.

  In this case, the user UA presses a dial button (in this example, “1” button) corresponding to the communication request information. Thereby, the communication source terminal 2 transmits the communication request information as selection information to the call control device 4 (step A62 in FIG. 6).

  As a result, the CPU of the call control device 4 determines “Yes” in step 530 of FIG. 5 and proceeds to step 535 to determine whether or not the received selection information is communication request information. In this state, the CPU determines “Yes” and proceeds to step 540.

  And CPU transmits the calling signal which calls the communication destination terminal 3 to the communication destination terminal 3 (step B64 of FIG. 6). Next, the CPU performs a call process between the communication source terminal 2 and the communication destination terminal 3 (step 545). That is, the CPU establishes communication between the communication source terminal 2 and the communication destination terminal 3 when receiving a response signal from the communication destination terminal 3 (steps A63 and C62 in FIG. 6). Thereby, a telephone call is performed between the user UA and the user UB.

  Further, the CPU of the call control device 4 deletes the call information acquired at step 520 from the storage device of the call control device 4. Then, the CPU returns to step 505, and repeatedly executes the processing of step 505 to step 565.

  Next, a case where the user UA desires to postpone the start of a call with the user UB when a message prompting to input selection information is notified will be described.

  In this case, the user UA presses a dial button (in this example, “2” button) corresponding to the communication postponement information. Thereby, the communication source terminal 2 transmits the communication postponement information to the call control device 4 as selection information.

  Thereby, the CPU of the call control device 4 determines “Yes” in Step 530 of FIG. 5 and determines “No” in Step 535, and proceeds to Step 550. Then, the CPU determines whether or not the received selection information is communication postponement information. In this state, the CPU determines “Yes” and proceeds to step 555.

  Then, the CPU stores the call prohibition information in the storage device of the call control device 4 in association with the call information acquired in step 520. Further, the CPU separately performs a process of deleting, from the storage device, the call prohibition information indicating the date and time prior to the current time among the call prohibition information stored in the storage device of the call control device 4.

  As a result, until the postponement time elapses, the calling signal is prohibited from being transmitted to the communication source terminal 2 based on the calling information associated with the calling prohibition information. That is, the transmission of the call signal based on the call information is postponed for the postponement time. As a result, the convenience of the user UA can be improved. Further, it is possible to prevent a call between the user UA and the user UB from being performed when the user UA forgets to call the user UB.

  Then, the CPU returns to step 505, and repeatedly executes the processing of step 505 to step 565.

  Next, a case where the user UA no longer wishes to talk to the user UB when a message prompting to input selection information is notified will be described.

  In this case, the user UA presses a dial button (in this example, “3” button) corresponding to the request cancellation information. Thereby, the communication source terminal 2 transmits the request cancellation information to the call control device 4 as selection information.

  Thereby, the CPU of the call control device 4 determines “Yes” in Step 530 of FIG. 5 and determines “No” in Steps 535 and 550 and proceeds to Step 560. Then, the CPU determines whether or not the received selection information is request cancellation information. In this state, the CPU determines “Yes” and proceeds to step 565.

Then, the CPU deletes the call information acquired in step 520 from the storage device of the call control device 4 without transmitting a call signal to the communication destination terminal 3. Thereby, thereafter, the calling signal is not transmitted to the communication source terminal 2 based on the call information. That is, the user UA can cancel (cancel) a request for communication between the communication source terminal 2 and the communication destination terminal 3. As a result, the convenience of the user UA can be improved.
Then, the CPU returns to step 505, and repeatedly executes the processing of step 505 to step 565.

  As described above, according to the embodiment of the communication system according to the present invention, the user (first user) UA who uses the first telephone terminal 2 inputs the selection information, so that the second call signal is transmitted. It can be determined whether or not to transmit to the telephone terminal 3. Therefore, when the position of the user (second user) UB who uses the second telephone terminal 3 becomes a position in the terminal usage area, if the first user UA does not want to talk, It is possible to prevent a call with the second user UB from starting. That is, the convenience of the first user UA can be improved.

  In addition, this invention is not limited to the said embodiment, A various modification can be employ | adopted within the scope of the present invention. For example, in the above-described embodiment, the callback process calls the communication source terminal 2, causes the user UA that uses the communication source terminal 2 to select whether to call the communication destination terminal 3, and calls the communication destination terminal 3. This is a process of calling the communication destination terminal 3 when is selected. By the way, when the callback process calls the communication destination terminal 3, the user UB that uses the communication destination terminal 3 selects whether to call the communication source terminal 2, and when it is selected to call the communication source terminal 2. It may be a process of calling the communication source terminal 2.

  That is, the call control unit 23, when the communication destination specifying information is stored in the storage device, when the user position UB 11 detects that the position of the user UB is a position in the terminal use area, the user UB When the selection information input is the communication request information for requesting communication with the communication source terminal 2, a call signal for calling the communication source terminal 2 is sent to the communication source terminal 2. It may be configured to transmit.

  According to this, when the user (second user) UB who uses the second telephone terminal 3 inputs the selection information, it is determined whether or not to transmit the calling signal to the first telephone terminal 2. Can do. Accordingly, when the second user UB does not want to make a call when the position of the second user UB reaches the position in the terminal use area, the user who uses the first telephone terminal 2 (first The user can be prevented from starting a call with the UA. That is, the convenience of the second user UB can be improved.

  In the above embodiment, the RFID reader 5 and the RFID tag 6 are configured to detect whether or not the position of the user UB is a position in the terminal use area, but the terminal is held by the user UB. The position of the user UB may be detected by a portable terminal having a GPS (Global Positioning System) function.

  Furthermore, in the above-described embodiment, the RFID reader 5 and the communication destination terminal 3 are configured as separate devices, but the function of the RFID reader 5 may be mounted on the communication destination terminal 3.

  The present invention can be applied to a telephone system including a plurality of telephone terminals and a call control device.
