This is information indicating that the slave unit 2 is called next to the main unit 2.

The timer section 26b operates when a call is made from the calling station 4 shown in FIG. 1, and causes the slave unit 2 to perform a response operation after a predetermined time has elapsed. The operation unit 27 is a unit for performing dial operation, registration of a telephone number in the storage unit 28, recording and reproduction settings of the recording / reproduction unit 23, operation, and the like.

In FIG. 1, a calling station 4 has almost the same function as a general calling station in a telephone system, but information S1 + D from a center memory 3 when a call is made on a telephone network 6.
The main unit 1 and the slave unit 2 are called based on 1, S2 + D2.

Next, the operation of this embodiment will be described.
First, in FIG. 1, when the position information S1 (position information S2) is transmitted from the base station A (base station B) to the master unit 1 ( slave unit 2), the position information S1 (position information S2) is transmitted to the transmission / reception unit 11 (transmission / reception unit 11). Unit 21) and sent to the control unit 16 (control unit 26). Then, the main unit registration unit 16a ( slave unit registration unit 26a) of the control unit 16 (control unit 26) uses the position information S.
Information S1 + D1 (information S2 + D2) is generated by adding priority D1 (priority D2) to 1 (position information S2). Then, the information S1 + D1 (information S2 + D2) is transmitted from the transmission / reception unit 11 (transmission / reception unit 21) to the base station A (base station B) via the antenna 10 (antenna 20), and is transmitted from the base station A (base station B) to the exchange. 5 and then sent to the center memory 3 for registration.

In this state, when a call is generated from the telephone network 6, the calling station 4 reads the information S1 + D1 and the information S2 + D2 from the center memory 3 based on the selection signal (telephone number) S3 from the telephone network 6, and gives priority. D1 recognizes that the main unit 1 is to be called first. As a result, first, the main unit 1 is called by the calling station 4. And
If there is no response from the main unit 1 to the calling station 4, the calling station 4 calls the slave unit 2 next.

Then, the calling signal is received by the transmission / reception unit 21 via the antenna 20 of the slave unit 2, and the control unit 26
Of the timer section 26b operates. After a lapse of a predetermined time, a response operation of the slave unit 2 is performed, and a response signal is sent to the telephone network 6 via the base station B, the exchange 5, and the calling station 4. As a result, a communication state with the external telephone 7 is established. At this time, if the recording setting of the recording / playback unit 23 has been made by the operation unit 27, the call sound from the telephone 7 is recorded in the recording / playback unit 23. This recorded content is reproduced by the operation of the operation unit 27.
The sound is reproduced and transmitted from the speaker 24 as sound.

The above operation is performed when the master unit 1 and the slave unit 2 are separately provided at different base stations A and B. When the main unit 1 and the slave unit 2 are in the same area, the position information S1 and the position information S2 have the same content. Therefore, depending on the information S1 + D1 and the information S2 + D2 read from the center memory 3, which information is the main unit 1 Information cannot be determined. For this reason, since the calling station 4 cannot determine the device to be called first, the calling station 4 simultaneously calls the master unit 1 and the slave unit 2 as shown in FIG.

When the simultaneous calling is performed, if the main unit 1 is in a state in which it can respond, there is a possibility that the responses of the main unit 1 and the slave unit 2 may compete. However, the slave unit 2 has a timer 26
b has, since slave 2 responds after a predetermined time has elapsed, the main
The response between the device 1 and the slave 2 does not conflict. At this time, if the response of the main unit 1 is not performed, the slave unit 2 responds, and the call sound from the telephone 7 is recorded in the recording / reproducing unit 23 by the recording setting of the recording / reproducing unit 23 in advance.

As described above, according to the call maintenance system of the portable telephone of the present embodiment, when a call of the telephone network 6 occurs, the calling station 4 causes the information S1 + D1, S1 from the center memory 3 to be transmitted.
On the basis of 2 + D2, the main unit 1 is called first, and when the main unit 1 does not respond, the slave unit 2 responds and the recording / playback unit 23 can record the contents of the call. in a case where the main machine 1 is in place does not reach radio waves, it is possible to slave 2 to complement the main machine 1, slave
Only the device 2 can receive the call from the telephone network 6 and record the contents of the call.

[0027]

As described above, according to the call maintenance system for a portable telephone according to the present invention, when a telephone network call is generated, the main station is controlled by the calling station based on the position information and the priority from the center memory. the first to be called, in a case where the main machine is no response, the slave responds, since it is configured to be able to record the call contents, the main engine even if you are out of the reach of radio waves, slave However, there is an effect that the main unit can be complemented, and the contents of the call can be recorded by receiving the call from the telephone network only by the slave unit .
