種動端末の消費電力を低減することが難しく、携帯形の
無線電話装置においては電池の小形化が困難であつた。In the conventional cellular type mobile communication system, the communication area is divided into a plurality of small zones, a call channel group of a different frequency and a call control channel are provided for each zone, and each mobile terminal handles an incoming call. Therefore, it was necessary to always wait and receive the call control channel. Therefore, it is difficult to reduce the power consumption of various mobile terminals, and it is difficult to reduce the size of the battery in the portable wireless telephone device.
この点に関しては、バツテリーセービング方式として
例えば特公昭59−12055では、各小ゾーンの無線チヤネ

ページング受信機４は常時待ち受け受信を行つている。In FIG. 2, the wireless telephone 3 is a paging receiver 4
It has a detachable structure and operates as an independent wireless telephone 3 and paging receiver 4 when they are separately used.
Reference numeral 51 denotes a switch for detecting the attachment / detachment state of the paging receiver, which is closed when the paging receiver is attached. In response to this, the power supply control unit 36 of the telephone device receives the transmission / reception unit 32, control unit 33, The power supply to the frequency synthesizer 34 is stopped, and the standby reception operation of the wireless telephone 3 is stopped. Further, each part in the paging receiver 4 is constantly supplied with electric power, and the paging receiver 4 is always on standby.
上記ページング受信機は現在広く実用化されているポ
ケツトベルシステムの受信機であるから、公知の間欠受

地局72〜74に対し、一斉呼出しを指示する。各無線基地
局72〜74はこれを受けて、各々が管轄するセル内に上記
複合端末６に対する呼出し信号82を送出する。In FIG. 3, when a call is made from the public line 71 to the composite terminal 6, the mobile communication control station 7 first instructs the radiotelephone base stations 72 to 74 to make a simultaneous call. Responsive to this, each of the radio base stations 72 to 74 sends out a calling signal 82 to the composite terminal 6 in the cell under its control.

ジング信号送出局８から送信される。On the other hand, in the composite terminal 6, assuming that the paging receiver 4 is connected, the wireless telephone 3 is in a dormant state and cannot answer this call. Therefore, the calling party or the mobile communication control station 7 knows that the composite terminal 6 is inactive after the elapse of a certain time, and then switches the call to the sending of a paging signal. This switching operation may be performed manually by the caller or automatically by the mobile communication control station 7. A paging signal 81 for the composite terminal is transmitted from the paging signal transmitting station 8.

Notifies the subscriber of the incoming call by means of sound, light, etc. and stores the received paging information in the paging information memory 45 once. As the paging signal according to the present invention, it is assumed that the caller's telephone number or the like is transmitted as paging information.

行う。The subscriber who knows the incoming call by the paging receiver 4 is
The call is made in reverse to the telephone number of the other party displayed on the display unit 44. For this purpose, the subscriber depresses the dial information transfer instruction switch 47 provided in the paging receiver 4. . This allows the paging receiver controller
43 retrieves the previously received paging information from the paging information memory 45 and transmits it to the dial unit 35 and the power supply control unit 36 of the telephone device via the information transmission connector 52. Accordingly, the power supply control unit 36 restarts the power supply to each unit in the wireless telephone 3. Since the paging information including the destination telephone number is also transmitted to the dial unit 35, the telephone control unit 33 makes a call based on this dial number.

を判断する。However, in the compound terminal according to the present invention, since the wireless telephone 3 is not always on standby, it is first known which service zone of the wireless base stations 72 to 74 in FIG. It may be necessary. In such a case, the zone to which the user belongs belongs is determined by the procedure described below.

に位置していると判断する。The radio base stations 72 to 74 of the respective cells are assigned a communication channel group and a control channel of different frequencies. The control channels in each zone are assumed to be C 1 , C 2 and C 3 , respectively. The wireless telephone 3 receives the channels C 1 , C 2 and C 3 in order, and if the wireless base station is transmitting on that channel, stores the signal strength thereof. If not,
A predetermined control signal is sent to the wireless base station and transmitted, and the wireless base station is requested to send out a carrier wave on the control channel. Then, the signal strength of the carrier wave transmitted from the wireless base station is measured and stored. The wireless telephone 3 compares the stored signal strengths and determines that it is located in the zone of the wireless ground station that holds the channel that has received the strongest signal.
次に上記無線電話機３は改めて発呼要求信号を無線基
地局に送出する。以後の発呼接続手順は従来の自動車電
話方式と同等であるから省略する。Next, the wireless telephone 3 again sends a call request signal to the wireless base station. The subsequent calling connection procedure is the same as that of the conventional car telephone system, and therefore will be omitted.

リ45をクリアすれば良い。Although the above procedure is for answering an incoming call from the other party, if it is determined that the call does not need to be answered, the transfer instruction switch 7 for paging information is pressed at the time of receiving the paging signal. Instead, the paging information discard instruction switch 48 may be pressed to clear the paging information memory 45.

If the configuration shown in the figure is used, the user can freely select whether long-term standby reception by the paging receiver or long-term call by the large capacity battery is possible. Is possible.
以上説明したもの以外にも、特許請求の範囲１に記載

体構造にすることも可能である。この場合の動作も前記
着脱式の複合端末と同様に行うことができる。In addition to what has been described above, as described in claim 1, the paging receiver can be built in the wireless telephone to have an integrated structure. The operation in this case can also be performed in the same manner as the detachable compound terminal.
以上、説明の通り本発明によれば、携帯用無線電話の

のの、着信呼は確実に加入者に伝達される。As described above, according to the present invention, it is not necessary for the wireless telephone itself to perform standby reception for the standby of the portable wireless telephone, and the battery saving is significantly effective. Further, since the standby reception itself is performed by a paging receiver such as a pocket bell, the incoming call is surely transmitted to the subscriber with some time delay.
次に本複合端末を着脱式に構成すれば、通常の無線電
話機としても、バツテリーセービングを行う複合端末と

が可能である。Next, if the present composite terminal is configured to be detachable, it can be used as an ordinary wireless telephone or as a composite terminal for battery saving, and can be freely combined according to the user's needs.
また本複合端末内にページング情報の伝達手段を設け
た事により、ページング呼出しを受けた際呼出し元へ一
挙動で発呼が可能であり、その利便性に関しては従来の
無線電話機を単独で使用する場合に比べ遜色がない。In addition, by providing a means for transmitting paging information within this compound terminal, it is possible to make a call to the caller with one action when a paging call is received. For convenience, the conventional wireless telephone is used alone. Comparable to the case.
さらに本複合端末に係る無線通信方式は夫々、従来の
セルラ形移動通信方式、ポケツトベル呼出し方式と何ら
