In this separate configuration, when corresponding to the above-described mobile phones 1 and 2 in FIG. 2, in FIG. 2, a portion surrounded by a broken line corresponds to the wireless unit set 15, and the other portions correspond to the handset 17. . As shown by the broken line in FIG. 2, the control circuit 3 and the voice processing unit 7 are divided into two functions in the shared communication terminal.

Such another configuration is such that the portable device can be used as an automobile telephone by bringing it into the vehicle and connecting the handset and the radio unit set 7, and the handset is not used in the vehicle. Information terminal (PD
By connecting A) to the wireless unit, transmission and reception of e-mail in the vehicle can be easily performed.

It should be noted that the wireless unit set 15 can receive power from a vehicle-mounted battery from a cigarette lighter power supply plug or the like. The handset 17 has a built-in secondary battery. When the handset 17 is installed on an in-vehicle mount (not shown), the rechargeable battery charged from the in-vehicle battery is charged.

In the present embodiment, the wireless unit set 15 and the handset 17 have the same BT communication unit 1 as described above.
The audio data received by the wireless unit set 15 is again modulated by the BT communication unit 16 and then received and demodulated by the BT communication unit 18 on the handset side, and output as audio. You. On the other hand, conversely, the input voice from the handset 17 is

In FIG. 1, reference numeral 21 denotes a fixed telephone (corresponding to the first or second communication terminal of the present invention) connected to a public line. As is well known, the incoming telephone call history is also stored in the fixed telephone 21 in a memory (not shown).

In FIG. 1, reference numeral 19 denotes a personal computer (corresponding to the first or second communication terminal of the present invention,
A personal computer, for example, can transmit and receive e-mail by connecting to a public telephone line. The received data of the e-mail (corresponding to the sender's mail address, reception date and time, and received call history) is stored in a storage medium (not shown) such as a built-in hard disk.

In FIG. 1, reference numeral 20 denotes a facsimile which transmits and receives image data (image data) which is non-voice data by connecting to a public telephone line.
Also in the facsimile, the received history (sender, subject, reception date, etc.) of the received FAX data is stored in a storage medium (not shown). And these landline phones, computers,
The facsimile also has the same BT communication units 22, 23 as described above.
Is built-in.

Here, in order to perform communication (frequency hopping spread spectrum communication) between the BT communication units 13, 16, 17, 22, and 23 in each communication terminal, initial setting is required. Let me explain briefly.

First, when the mutual BT communication units are set to the initial setting mode, an initial wireless link is established without any authentication. Next, in this state, a password (for example, a four-digit number) is input to one of the devices. The input password is sent to the other device, and the initial setting is completed.

Thus, the BT communication unit can be connected to each other. For example, when one device is operated to enter the BT mode, the password is automatically transmitted, and the device that has received the password is registered previously. If the password is the same, the wireless connection is established.

Also, in this example, by such registration,
As shown in FIG. 1, for example, the handset 17 is capable of wireless communication with other communication devices 1, 2, and 19 to 21 at each BT communication unit, thereby enabling data exchange between each communication terminal. Becomes possible. In addition, each BT communication unit associates the attribute (telephone, FA) of the partner communication device with the password.
X, data identifying whether it is a personal computer).

Therefore, the fact that such communication devices can communicate with each other means that a plurality of communication terminals (master units) can receive an incoming call with a common slave unit, as described in the means for solving the problem. It turns out that. For example, in FIG. 1, the handset 17 not only receives an incoming call to its own telephone (an incoming call to the wireless unit set 15) but also the mobile phones 1, 2,.
Receiving an incoming call from a landline phone, you can talk.

Further, which communication terminal can freely set a master unit, a slave unit, and the like. As shown in FIG. 3, it is possible to set the communication terminal of the call receiver by using the above-described attribute data as the slave unit setting. FIG. 3 shows a setting display screen of the handset 17.

The handset 17 includes not only the slaves of the fixed telephone 21 and the portable telephones 1 and 2 but also the handset 17.
0 and the personal computer 19 can be communicated with the BT communication unit. The facsimile 20 transmits a sender, a subject, and the like to the handset in conjunction with its own reception processing. In the case of the personal computer 19, the sender, subject, and the like of the electronic mail are transmitted to the handset 17 by the BT communication unit in conjunction with the reception processing of the electronic mail. Such data transfer setting is also possible by setting using the attributes shown in FIG. However, in FIG. 3, the handset 17 is described as a child device, the FAX 20 and the personal computer 19 are described as the parent device of the incoming call history data transfer as the parent device.

Next, the operation of this embodiment will be described with reference to FIGS.
This will be described with reference to FIG. The following description is based on the assumption that FIG.
As shown in, the handset 17 is already wirelessly connected to the mobile phones 1 and 2, the fixed telephone 21, the facsimile machine 20, and the personal computer 19 by BT communication.
It functions as a slave of the mobile phones 1 and 2 and the fixed telephone 21. FIG. 4 shows a fixed telephone 21, a personal computer 19, and a fax 2.
0 is a diagram collectively describing processing operations of the mobile phones 1 and 2.

In the following, if there is an incoming call to the mobile phone 1, 2 or the fixed telephone 21 in FIG.
Go to 10. Next, in step S420, the data indicating the incoming call and the incoming call history data are transferred to the BT communication unit (13, 22).
Is extracted, and these data are transmitted to the handset 17 in step S430.

On the other hand, if the incoming call (reception) is the facsimile data of the facsimile 20 or the e-mail of the personal computer 19 (step S440), at step S440, the sender (FAX number if FAX) is sent from the transmission partner , Email address, subject's email address, subject)
Is transmitted to the handset 17 via the BT communication units 23 and 24.

On the other hand, FIG. 5 shows an operation of receiving the incoming call history data transmitted in FIG. 4 by the handset 17. First, the incoming call history data is received in step S500, and then in step S510. The incoming call history data is classified according to the attribute of the communication terminal that is the parent device. Next, the divided data is stored in a memory (corresponding to the storage unit 12) in step S520.

Thus, for example, as shown in FIG. 6, if the destination is the mobile phone 1, the incoming call history is displayed in the column of the mobile phone 1 when the history is displayed. As shown in FIG. 6, the incoming call history is displayed as a list for each communication terminal as shown in FIG. 6. However, as shown in FIG. By using the handset 17, for example, the mobile phones 1 and 2, which are frequently used, can be displayed at the top of the list.

Next, after storing the incoming call history data in such a memory, in step S530, handset 17 returns an acknowledgment signal indicating reception to the communication terminal of the transmission source, which is the master unit.

The incoming call history data received by the handset 17 is displayed as shown in FIG. 6, and the data itself can be reused by the handset 17. FIG. 8 illustrates this process. Step S8
When the data is read from the memory as shown at 00, the screen shown in FIG. 6 is displayed. Next, in step S810, the destination is selected from the incoming call history by moving the cursor on this screen by key operation.

Next, in step S820, it is determined whether the selected destination is an e-mail or a telephone. When a call key (not shown) is operated, the other party is transmitted to the other party via the wireless unit set 15 in step S840. You can make a phone call. on the other hand,
If it is determined in step S820 that the email is an email,
After creating the sent mail message to the other party, the mail is sent by a predetermined operation (step S830).

In the above example, the handset 17 has been described as being in communication with all communication terminals by the BT communication unit 16 as shown in FIG.
7 can be added to the handset 17 even when the terminal 7 is brought out of the BT communication area. This will be described with reference to FIGS.

In FIG. 5, when the handset stores the incoming call history, the handset transmits a confirmation signal to the communication device of the other party. On the other hand, the communication terminal that has received the confirmation signal stores the data indicating that the communication has been transferred according to its own incoming call history.

Then, the handset 17 is moved to B shown in FIG.
Bring into T communication area, BT communication mode (power on)
In this case, the communication terminal is wirelessly connected to the communication terminal. However, the other communication terminal first determines the unsent incoming call history data as shown in step S910 in FIG. If there is, the data is transmitted to the handset 17 in step S920. Handset 17
Receives this, and saves it as classified for each communication terminal as described with reference to FIG.

As described above, in the present embodiment, it is possible to display and browse the call histories of a plurality of master units with a handset as a slave unit, thereby improving convenience. Also, incoming call history data in the handset can be reused, and if the data is a call history, it is possible to make a call as it is, further improving convenience. In addition, incoming call history data indoors can be reliably updated while the handset is taken out of the B-communication area.

Also, in the present embodiment, incoming history data at terminals having different communication modes, such as the facsimile 20 and the personal computer 19 which are non-voice data terminals and the fixed telephone 21 and the mobile phones 1 and 2 which are voice data terminals, are stored. , And can be browsed and displayed on the handset 17, thereby improving convenience.

The present invention is not limited to the embodiment described above and shown in the drawings, and the following modifications or extensions are possible.

In the above embodiment, the incoming call history data of another communication terminal is collected in the handset 17.
Instead of the handset 17, the mobile phone 1 or 2, the fixed telephone 21, or the personal computer 19 may be used.

In each of the above embodiments, only the sender data and the subject are used as the incoming history data from the facsimile 20 and the personal computer 19, but all the image data is used for the facsimile, and the text and the attached file are also used for the electronic mail on the personal computer. May be sent to the handset 17.
