Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device and a communication method for performing communication using data transfer means capable of simultaneously transferring voice and data.

[0002]

2. Description of the Related Art In recent years, notebook computers and dedicated handy terminals have been used during business activities (outings) due to downsizing of computers such as notebook computers and computerization of inventory management and slip processing by POS systems. You can now access information within the company via the line. As a result, it became easier for customers to collect information and check inventory, and it became possible to respond quickly.

Behind this, an environment has been established in which the electronic equipment can be used on an individual basis due to high performance miniaturization and cost reduction, and the radius of information movement due to the expansion of the wireless telephone service area and the price reduction. Expansion is also added.

In addition, the conventional modem (data, FAX) is
Modulation is applied to transfer digital data to an analog telephone line that transmits voice, and normal voice communication was not possible during data transfer. However, there has been recently developed a modem capable of simultaneously transferring voice and data (data, FAX) by a method such as time division or double carrier when the same modem is used for both.

[0005]

However, not only when using a modem that can only send data, but also when using a modem that can simultaneously transfer the data and voice, the data can be transmitted while making a voice call. There was no way for the user to know the condition. Therefore, it was not easy to use. Further, when voice communication and data communication are simultaneously performed for different purposes, the progress statuses of the respective communication sometimes conflict with each other.

The present invention has been made in view of the above points, and an object thereof is to provide a communication device and a communication method with improved usability.

[0007]

In order to achieve such an object, according to the first invention of the present application, a communication means capable of simultaneously transmitting and receiving voice and data by one line, and voice and data by the communication means. From the state of simultaneously transmitting and receiving data, when the voice communication is completed before the data communication is completed, the notification means for notifying that the data is being transmitted and received, and the communication means It has a control means for controlling so as not to newly start the communication by voice during the communication. Further, according to the second invention of the present application, data communication can be performed from a communication means capable of simultaneously transmitting and receiving voice and data on one line and a state in which the communication means simultaneously transmits and receives voice and data. Before terminating, in response to the recognizing means recognizing that the voice communication has ended, and the recognizing means ending the voice communication,
Generating means for generating an audio signal. Further, according to the third invention of the present application, after the communication means capable of simultaneously transmitting and receiving the call voice and the data via the line and the call voice and the data are simultaneously communicated, the communication by the call voice is terminated,
And before the data communication is completed, the recognition means for recognizing that a new communication start instruction is generated, and the recognition means for recognizing that a new communication start instruction is generated Control means for interrupting communication and disconnecting the line. Further, according to the fourth invention of the present application, after the communication means capable of simultaneously transmitting and receiving the call voice and the data via the line and the call voice and the data are simultaneously communicated,
The communication means for recognizing that a new communication voice communication start instruction has been issued before the communication with the communication voice and the communication of the data has ended, and the communication start instruction with the communication voice by the recognition means are issued. In response to recognizing that the communication has occurred, the communication is continued until the data communication is completed, and a notification unit is provided to notify that communication with a new call voice is impossible.

[0008]

The notifying means notifies the user of the data transmission / reception state of the data transfer means.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, FIG. 1 shows a schematic diagram of data transmission / reception on a public line using a communication apparatus according to an embodiment of the present invention. A portable electronic device (pen computer in the figure) 1 has a built-in wireless telephone function. As a telephone, it can be used by instructing the soft numeric keypad displayed on the screen or the address book number, and the voice is exchanged with the operator through the second handset. The electronic device may of course be the existing laptop computer 3 without a built-in wireless telephone. In that case, the modem 4 is attached to the PCMCIA interface of the electronic device 3. The mobile phone 5 can also wirelessly transfer data by connecting to the modem 4 by a general mobile wireless phone. The modem 4 as the data transfer means of this embodiment can transfer voice and data at the same time.

Therefore, in the apparatus of this embodiment, voice is also transmitted through the modem 4, that is, voice information is converted into digital data, modulated by the modem 4 and output to the line.
The receiving operation is the opposite.

These two types of portable electronic devices are used on the go, and the personal computer or host computer 7 is a machine that can manage order slips, stock status, and individual schedules in a fixed place such as in the office. Modem 4
Is connected to a public line. The telephone 6 is an ordinary telephone used in normal business. The public line may be a wireless telephone or a wired connection. In this embodiment, the portable electronic device is illustrated as the destination, but a desktop machine at a branch and a fixed machine such as a host computer at the head office may be used.

FIG. 2 shows the portable electronic device 1 and A of FIG.
FIG. 3 is a schematic block diagram showing the configuration of the block shown as “1”. The configurations of these two are almost the same except that, for example, the types of CPU devices are different.

In FIG. 2, reference numeral 8 is a CPU for controlling the electronic device 1 or A, and 9 is a CP such as a memory controller.
Peripheral I / O in which U peripherals are integrated, 10 is RAM, 11 is ROM, 12 is an input device, and a digitizer for a pen computer and a keyboard for a notebook computer are standard. 13 is a VGA of the display controller, and display 1
4 may be a liquid crystal or a CRT. Reference numeral 15 is a hard disk for storing a large amount of programs and user data, and 16 is an interface (PCMCIA) of an IC card which is now standardly attached to small electronic devices.
Is also attached to this. Of course, it may be built in instead of such a removable card. The wireless unit 17 transmits and receives radio waves according to the plan of the wireless telephone. The line control 18 is an operation for making a call, that is,
It controls the line such as notifying the wireless network through the wireless unit by the operation to raise the handset to go off-hook. Hook controller 20 is CP
A line connection request or disconnection request from U is transmitted to the line control 18. The hook state of the handset is actually C once.
It is executed after the PU determines the overall state. As a result, as will be described later, even if the user is in the on-hook state, the data transfer is continued as it is. In the voice signal generating means 19, when one of the two communicating parties making a call puts the handset on-hook, a pseudo dialing tone at the time of disconnection indicating to the other communicating party is generated instead of the exchange. The DTMF signal is generated or a DTMF signal is generated. Reference numeral 21 is an I / F for connecting to a wired line such as RJ11.

FIG. 3 is a diagram showing a procedure for actually performing data communication and voice conversation in the system disclosed in this embodiment. It does not matter whether the sending side and the receiving side are each outside the office or inside the company.
In this example, it is assumed that there is data to be updated only on the transmission side.

First, the sender is the handset 2 or 2 '.
Raise or go to the "on-hook" state by a hook icon (not shown) on the screen. As a result, the line with the exchange is opened, and the exchange returns a dial tone that has received the notification. When it is confirmed, the electronic device itself dials automatically or according to a predetermined software. At this time, the CPU 8 in the system is monitoring the dial and checks whether the dial number matches that registered in advance. The dial number registered in advance is the number of the terminal having a modem as the other party that can simultaneously send voice and data.

If it is confirmed that they match, the other party is equipped with a modem capable of sending voice and data at the same time, and there is a possibility that both parties have data to be sent to the other party. Regardless of how they are used, the ability of a modem to send and receive voice and data simultaneously, a channel for sending data, i.e. a background channel, is used to send data communication packets to each other and to each other. Confirm the IDs (identification information) of each other. If there is data to be sent on one or both sides, it is sent in packets in data units, and the receiving side performs an error check each time and returns ACK if it is okay.

When the data communication is started, the user is notified of the fact. The notification means may display "data transfer in progress" on the display 14 or may be a simple one such as an LED (not shown). The data is sent from the transmitting side, and when all the data has been sent, the receiving side then sends back the data, if any (not shown in FIG. 3).

Since these data exchanges proceed regardless of the voice call, and the situation does not affect the user's conversation or behavior, the user puts the handset on-hook as soon as the voice call is completed. Or you hang up the phone by operating the hook icon on the screen.

However, if the data transfer is in progress,
The line control 18 keeps the line connected. At the same time, in order to recognize that the other party of the voice call hangs up the other hand, the disconnection tone is emitted by the voice signal generating means 19. At this time, the data continues to be sent in the same way, and the line is disconnected without the user being aware of it when both sides have sent it.

Since the lines are connected, the charges are the same, so that the user may continue to make a voice call. So, if we know how much data transfer is still going on, we can talk differently accordingly. The user displays "remaining time" together with "transferring" so that the user can know the remaining time at any time. Of course, it may be displayed according to the user's request.

4 (a) and 4 (b) are flowcharts for realizing the above diagram. First, FIG. 4 shows a procedure when data is updated by taking a case where the system of this embodiment has a scheduler function as an example.

(A) shows a case in which the schedule of the owner of the portable device is confirmed or an appointment is made by communication with the personal computer 7 side. First, (4-1) receive data, (4-2) interpret the command as to what the received message requires (here, (4-3) schedule confirmation and (4-5) appointment If the command confirms the schedule, (4-4)
The schedule data on the personal computer 7 is returned. Also, if you want to make an appointment, if the schedule is free, register as (4-6) temporary data and (4-
7) A flag indicating that the updated data exists is set, and (4-8) a table of the number of the updated data units is stored and the pointer of the existing location is stored.

(B) shows a flow when the user registers or modifies a new schedule on either a personal computer or a portable electronic device. In this case, if new data is entered on the go by the mobile terminal where (4-9) and (4-10) are performed, and provisional data registration is also performed on the personal computer, both sides are inconsistent and are matched. The need comes out.

FIG. 4C shows an example of the update data table in the personal computer or the portable electronic device 1. The number (acceptance order), data type (schedule, FAX, order, etc.), date / time, data capacity, A pointer indicating the memory in which data is actually stored and communication records (communication start and interruption) are made for one data. If there is more than one, there is a table.

Next, FIG. 5A shows a flow chart of data communication which is carried out in parallel with the voice call on the calling side when there is data to be updated as shown in FIG. 4C. This may be either the personal computer 3 or the mobile device 1.

(5-1) As described above, the user dials by connecting the line and dialing as if he / she normally makes a call, or by designating the other party to call. (5-
2) Make sure that the dial you are dialing is registered in advance. If it is a number other than registration, it is assumed that the call is voice only, and no data communication is performed (5-3).

(5-4) When it is the registered number, the modem 4 is permitted to prepare for data transfer, and (5-5) the response of the other party is waited for. Although not shown, when the other party is busy or not on the phone, the user gives up the call by turning on the handset or the like, so this flow is also interrupted.

(5-6) In response to the other party, the user's own ID is transmitted as data in parallel with the voice conversation. And
(5-7) Waiting for the reply from the other party, (5-8) collating the incoming ID, and (5-9) determining whether it is normal. If the other party does not respond to the ID for a certain period of time or if the ID does not match, only voice calls will be handled.

In this case, it is not necessary to communicate via the modem 4.

(5-10) Next, the caller is shown in FIG.
It is confirmed whether the update data flag shown in (c) is set. If there is (5-11), it is packetized and sent according to the order entered in the data table. (5-25) Next, both sides transfer the amount of data to be sent and calculate the time required for data transfer. The amount of data is the sum of the total of its own data table and the amount sent from the other party. Then, the message "start data communication" is displayed on the display unit, and the remaining communication time is displayed at any time. (5-1
2) Each time, confirm that the data has been transmitted successfully with an ACK message from the other party, and (5-13) delete the transmitted data from the table. And (5-14)
Check whether all the data have been sent, and if not, return to (5-11) to send the next packet.

When all the processes are completed (5-15), a flag indicating the existence of data to be updated is reduced.

When there is no data originally, and when the sending has been completed, (5-16) a message with no data is sent, and (5-17) waiting for a reply from the other party. (5-1
8) On the contrary, if there is a partner, the data is received. If there is no partner, the data transmission / reception ends there. In (5-19), the status of the voice call is checked, and when it is still busy, the voice call state is set. If the conversation has already ended and the handset is on, this disconnects the line (5-20).

Here, the processing of (5-25) will be described in detail with reference to FIG.
It shows in (a). In (17-1), the total amount of data to be transmitted in the data table is calculated. And (17-
2) Send this data to the other party (17-3) and then receive the other party's data (17-4) and add it to the own data amount. (17-5) Obtain the actual transfer time from the data capacity and the transfer rate, and empirically add the time required for the procedure to obtain the required time. (17-6) Display "in communication" and "required time" on the display means 14. FIG. 17B shows a flowchart for correction of the required time after the start of display. The 1-second interrupt is used by the system for various purposes, but only this part will be described. (17-
7) Decrease the displayed time by 1 second (17-8)
If it is not 0 seconds, it is judged, and if it is not, it is ended as it is, and if it is, it is further judged (17-9) whether the communication is actually ended, and if it is (17-10)
Turn off the display during communication. (17-11) If the communication is not completed, there is a time error in the actual call.
Reset the time again from the current communication progress.

In FIG. 5B, the confirmation of the telephone number of (5-2) shown in FIG. 5A will be described in more detail. Depending on how the telephone number is set, it can be divided into two modes. First, (5-21) is a case where a telephone number is manually input directly. In the electronic device 1, the soft numeric keypad displayed on the display screen is pressed with a pen to input. On a general laptop computer, press the keyboard or numeric keypad. Since this is an input device of an electronic device, it is possible to grasp the number pressed by software. (5-22) The numbers are sequentially stored. Second, instead of directly pressing a key such as an address book, telephone directory, or speed dial in an electronic device, a previously stored number is called by a related key (5-2.
3). In this case, the target number can be known as soon as the user gives an instruction. It is compared whether or not the input target telephone number matches the pre-registered transmission target number. At this time, the presence or absence of the area code can be inferred.

FIG. 5 shows the control flow of the device on the calling side, whereas FIG. 6 shows the control flow on the receiving side.

Since some parts are basically the same, only the differences will be described. First, the phone bell rings and someone answers.
I don't know who got it here, so I'll wait until some information data is sent from the data side (6-
3). If there is no fixed time, it is judged that it is from an ordinary telephone that does not have a simultaneous voice data communication function, and then a voice call is made. If the ID is sent, and if it is appropriate, the other party's data is first received, and then this data is sent (the other details are the same as those in FIG. 5, so description will be omitted).

Next, FIG. 7 shows an interrupt process when the voice conversation is completed. The interrupt is configured to occur when the user clearly indicates the end of the voice conversation, such as the handset being turned on or the hook icon being indicated, and the flow of FIG. 7 is executed.

In this service routine, it is first confirmed whether the data transfer is continued (7-1), and if it continues, the line is left as it is and the sound heard from the line seems to be hung up. A different cutting tone is generated (7-2). In response to this, it is observed whether the other party disconnects (is on-hook) (7-3), and if it is on-hook and disconnected, the tone generation is terminated (7-4). Also, if the data transfer is completed even if the other party is not on-hook,
The flow branches to (7-1) and the line is disconnected as it is (7-5).

FIG. 18 shows an example of a display screen. Data transfer and required communication time are displayed as one of the windows. If you want to interrupt the communication, you can either click the interrupt icon or touch with the pen. FIG. 19 shows the operation when the interruption is instructed.

(19-1) Instead of data transfer, an interruption message is sent (19-2), and the other party's consent is awaited. (19-3) Turn on / off the handset to see if you are currently on a call.
If the call is judged to be off and the call ends (19-4), the line is disconnected. Next, the data sent halfway is processed. (19
-5) First, at the time of interruption, it is determined whether data or ACK was sent or received from here. (19-6) If it is transmission, further data or ACK is checked, and if it is data, an interruption message is written in the communication record of the data table. To finish (19-7). (19-8) If the ACK is being transmitted, the data packet just received is discarded. Similarly on the receiving side,
It is determined whether it is data or ACK (19-9) and the same processing is performed (19-10).

Further, even though the user is informed that the data transfer is in progress, when the user once ends the call and again indicates the intention to start the call by raising the handset, a warning as shown in FIG. 20 is displayed and , Do not enter the next call operation. The user can enter the next call by waiting until the data communication ends or by ending the communication in response to the interruption instruction.

(Embodiment 2) In the above-mentioned embodiment, the message display on the display means 14 is used as the notification means for the user.

In this embodiment, an example of using the audio signal generating means 19 to make an audio notification is shown.

FIG. 21 is a flowchart of the modified example of FIG. 17, and only different points will be described. (21-6)
When the data transfer is started, it is superimposed on a normal voice conversation and "Data communication has started. The time is 3 minutes."
Is issued from the voice signal generating means 19. Further, the user may be made to recognize by playing a predetermined sound quality such as a buzzer or a chime. (21-1
0) At the end of communication, notify by voice as in “Data communication is completed.” Or play the specified sound quality. When the communication time is changed (21-11) (12-6)
Informs the time after the change.

Further, even though the user is informed that the data transfer is in progress, when the user once ends the call and lifts the handset again to indicate that the call is to be started, "Data transfer is not completed. Please wait for 1 minute. "And the like from the handset to inform the user.

Although the display and the voice have been described as different embodiments, the combined notification of the display and the voice may be given.

As described above, according to this embodiment, when data and voice can be sent at the same time, even when the user makes a call for the purpose of voice communication, the data can be updated automatically without the user's concern. It is now possible to do so and the usability is improved. Furthermore, by notifying the status of data communication, it becomes possible to effectively use the voice call for a long time.

Furthermore, if the user tries to enter the next telephone call while the data has not been transmitted yet, a warning message is issued and the accuracy of the data transfer can be improved.

As described above, when there is data to be mutually updated using the modem capable of simultaneously transmitting voice and data,
An example has been shown in which the user is notified when exchanging data in the background of the phone that the user normally makes.

(Modification 1) In the above-described embodiment, the number pressed by the push button or the soft numeric keypad (telephone screen) as the telephone number confirmation means is used as the determination means for determining whether the communication partner is a specific partner. They were compared and judged by monitoring and registering names such as speed dials or address books (phone books).

In the present embodiment, an electronic device which does not have such a telephone function, for example, the notebook computer 3 shown in FIG.
However, I made it possible to monitor the number when dialing using an external mobile wireless phone.

The structure of this embodiment is shown in FIG. In this embodiment, the modem 4 (PCMC
IA card) and a DTMF receiver 22 for monitoring the dial signal DTMF emitted from the mobile phone.
Added. The DTMF receiver is a commercially available IC, and when it senses DTMF, it generates an INT (interrupt signal) and can sequentially notify the system of the pressed numbers. By storing this in (5-22) of FIG. 5B, it is possible to similarly determine whether or not an external telephone is trying to make a call to a previously registered partner.

(Modification 2) In the above embodiment, the update data table has been described as having only one transmission path, but the schedule is divided from the personal computer of the branch office and the order data from the host computer of the head office. In some cases, it is necessary to send the data of the corresponding terminal according to the type of information.

Therefore, FIG. 9A shows a plurality of update data tables in which transmission destinations can be set. The destination exists in each application by default (in the above example, the schedule data should be sent to the branch's own PC),
It may be set individually by the user. When transmitting this, in FIG. 5 (5-11), it is checked whether or not the data in the table matches with the transmission destination of the telephone number being called, as shown in FIG. 9 (b) ( 9-1), if they do not match, go to the next table (9-2), and if they match, transfer the data (9-3). After that, the flow returns to (5-11) in FIG.

As a result, data can be sent to a plurality of destinations. Further, a flag with update data may be created for each destination of update data.

(Modification 3) In the above embodiment, when one of the users makes a call, the update data is automatically exchanged in the background. However, it is desirable that confirmation of the schedule and urgent fax transmission be performed within a certain period of time.

Therefore, in this embodiment, when updating the data,
An example of activating a timer set according to the urgency of the updated data and notifying the user or automatically transmitting when a call is not received even after the time determined by the timer is shown.

FIG. 10 is a flow chart when the data is updated. The process up to the middle is the same as in FIG. (1
0-9) (10-13) When data is set in the update data table, a timer is set according to the type of the data. For example, 1 hour for data of scheduler update and temporary data registration, 2 for FAX reception.
0 minutes, etc. It should be noted that such a fixed default value may be used, but if the schedule confirmation is performed with a recently proposed network description language, the update time limit should be included in the command interpreted in (10-2). You can send it.

(C) shows an example of notifying the user in the interrupt routine when this time limit timer expires. If the electronic device is in the OFF state prior to the interrupt routine, turn on the power as well as the alarm.
To do. (10-14) In order to inform the user, a message prompting the user to update the data is displayed on the screen of the display 14 together with a sound warning such as a buzzer. On this screen, the type of data, the person to send, the telephone number, etc. are displayed.
(10-15) User OK? By confirming the intention of (10-16), the display 14 is turned off and the process ends.
Although not shown here, it is also possible to set the telephone to be called by OK to be automatically on-hook dialed.

(D) further shows an example of automatic updating.
(10-17) On-hook dialing is automatically performed in the interrupt routine to call the other party. However, when the user is currently using his / her own telephone, even if this interruption occurs, it cannot be serviced immediately, so the user sets the time again and exits.

(10-18) If it is judged from the calling tone of the other party whether or not there is a response, (10-19) the confirmations are made mutually. (10-20) If it can be confirmed, as described in the above embodiment, all the data to be updated existing in the table will be updated.

If the call is not answered even if the call is continued for a certain period of time or more, or if the user is busy, a certain period of time is set and the process ends.

As described above, in this embodiment, when the data is not updated for a certain period of time or more, the user is notified or automatically transmitted, so that the consistency of the data can be maintained within the certain period of time. And the transmission of information became faster. This example can be applied regardless of the condition that data and voice are sent simultaneously.

As described above, in the present embodiment, when data and voice can be sent at the same time, even when the user makes a call for the purpose of voice communication, the data can be updated automatically without the user's concern. The usability has improved. Furthermore, since one line can be used for two purposes, the call charge can be saved.

(Modification 4) Next, in the above-mentioned (Embodiment 1), when the voice call is ended during the data communication,
The diagram in FIG. 11 shows the response when the user lifts the handset to make another voice call again or operates the hook icon on the screen.

In the embodiment shown in FIG. 11, the user can communicate the updated data in the background before he / she cares during the voice call. Interrupt the data communication,
Disconnect the line and prepare for the next call. In order to suspend the data, a suspend command is sent instead of the data, and the other party returns a suspend confirmation message and disconnects the line from each other.
Then it goes off-hook so that the user can dial again by connecting the line. In the figure, the transmission side is off-hook during the transfer, but of course, whichever side the voice call is made, the same operation is performed.

FIG. 12 shows a flowchart of the device on the side where the user tries to make a call again. The user indicates the intention of the call by raising the handset or operating the hook icon on the screen, and this is used as a trigger to perform the interrupt routine. First, the electronic device confirms whether communication is being performed in the background (12-1). If data transfer is not in progress, the normal telephone mode (FIG. 5) may be entered as it is. During the data transfer, in order to promptly interrupt the data transfer so as not to burden the user on the data communication as described above (12-2), the data is once terminated and the interrupt command is sent. Then, after waiting for the confirmation message of the other party to come back (12-3), the line is disconnected (12-4). Next, the data sent halfway is processed. For example, processing is performed so that processing such as retransmission can be performed later. First, at the time of interruption, click here for data or AC
It is determined whether K has been sent (12-5), if it is transmission, it is further checked whether it is data or ACK (12-6), and if it is data, an interruption message is put in the communication record of the data table and the telephone mode is entered. If the ACK is being transmitted, the data packet just received is discarded (12-8). Similarly on the receiving side,
Depending on whether it is data or ACK (12-9), if it is data, it discards the data, and if it is ACK, it puts an interruption message in the communication record of the data table and shifts to the telephone mode.

FIG. 13 shows a flowchart on the electronic device side as a communication destination. In the case of this interrupt, normal data is abnormally terminated (ECC error), and the interrupt command is continuously received to enter the interrupt routine. First, send back a message confirming the interruption (13-
1), disconnect the line (13-2). Then, similarly to the above, depending on the transmission / reception state, processing is performed so that an abnormality does not occur in the data or message in the middle (13-3 to 8).

As a result, this electronic device ends the communication and returns to the default state.

As described above, when there is data to be mutually updated using a modem capable of simultaneously transmitting voice and data,
An embodiment has been shown in which the data is exchanged without the user having to worry about it in the background of the phone that the user normally makes.

(Modification 5) Different from the above embodiment, depending on the urgency and importance of the data, the data transfer may be prioritized.

Therefore, in the present embodiment, although the data transfer of the specific data set by the user or the data type (for example, order data) is not completed, the important data is being transferred when the user tries to call again. Is to be notified.

FIG. 14 shows the digram. First,
When confirming the other party, a message indicating whether or not priority data (with priority flag) exists in the current data table is added. When the user goes off-hook, it checks if the priority data is still being transferred, and if it is, the message that is being transferred is voiced from the handset to the user and displayed on the display screen. Prevent it from being hung. Although not shown in the figure, when the transmission of the priority data is completed, a priority data completion message is added after the data. This allows both parties to confirm the existence of the priority data. As for the order of data to be transferred in the above example, the data entered earlier (the one with the smaller table number) was sent, but in conjunction with the priority flag,
The order of transmission is such that the priority flag is sent first.

A flow chart at this time is shown in FIG.

In such a case, it is executed by an interrupt according to off-hook. At the time of such an interruption, it is determined whether or not data is being transferred (12-1). If it is not being transferred, the telephone mode is set. If it is being transferred, the presence or absence of priority data is confirmed in (15-2). The presence / absence of priority data is determined by whether or not the data to which the priority flag is added in the data table shown in FIG. 16 has not been communicated with the other party. As described above, the existence of the other party depends on the priority data existence message and the priority data completion message at the time of confirming the first party. The priority flag of the table can be set by the user as a default data type such as an order slip, or can be individually set when an emergency meeting is scheduled. Also, when the confirmation of the schedule written in the above-mentioned network description language comes from another person, the importance can be presented in the description language, so that it is interpreted and a priority flag is set.

If there is priority data, the flow branches from (15-2) to (15-12), and the voice synthesis output from the voice generating means 19 is added as a data transfer message, and "data transfer is in progress". It is also possible to display a message indicating that data is being transferred on the display as well as alerting with a warning sound (buzzer). Further, it is possible to prevent the user from actually making a call by not displaying the telephone mode soft dial. If there is no priority data, the same processing as described in FIG. 12 is performed.

Then, when the transfer of the priority data is completed, the electronic device informs the user again to permit the use of the telephone. That is, as a display, the transmission of the priority data is completed, the telephone can be used, and the like.

As described above, according to this embodiment, when data and voice can be sent at the same time, even when the user makes a call for the purpose of voice communication, the data can be updated automatically without the user's concern. It is now possible to do so and the usability is improved. Furthermore, since one line can be used for two purposes, the call charge can be saved.

Furthermore, if the user wants to enter into the next telephone call while the data that needs to be transferred early has not been sent yet, a warning message is issued and the accuracy of data transfer can be improved.

(Other Embodiments) Although it has been described that the timing for issuing the voice notification is arbitrary, a means for detecting the voice level of the voice information of the line is further added inside the voice generating means 19 so that the user is in a voice call. Or between talks,
The voice message may be controlled to start at the timing between talks.

Further, a buzzer or a chime sound may be emitted to call attention, and it may be confirmed by the voice level detecting means that both voice calls have been stopped, and the voice message may be started. As a result, the voice message can be played without disturbing the call, and the content of the message can be reliably transmitted to the caller.

The voice level detecting means monitors the voice line (connected to the handset) after the data and voice are separated by the modem 4, and determines whether the sum of the transmission and reception levels is equal to or higher than a predetermined level by analog (comparator). )
Alternatively, it is detected digitally (compared after A / D conversion).

[0083]

As described above, according to the present invention, according to the present invention, it is possible to improve the selfish use of when to send and receive data and voice at the same time. In particular, even if the purpose of data and voice is different on one line, they can be transmitted at the same time, and the call charge can be saved.
Furthermore, even if only the voice is cut off, the user can continue data communication without being conscious of it, and the data can be surely transmitted.Also, informing the user that data communication is being performed, By preventing new communication, it is possible to unconsciously disconnect the line and prevent data from being cut off during transmission.
