Control channel C-CH from one or more radio base stations as needed through
To make a selective call, and after the call is completed, call channel S
Switch to -CH and talk.

On the other hand, when there is a call from the terminal station 31 to the portable telephone 10A, the incoming signal is supplied to the wireless calling terminal 34 via the mobile telephone exchange 33. Here, the mobile phone number, the reception reference number of the wireless base station and the calling phone number (terminal station number) are stored as messages,
The receiver 1 in the mobile phone 10A is called by a wireless call (paging) via the wireless transmitting station 35 to transmit the message. The receiver 1 receiving the call turns on the power of the main body 2.

Next, when the antenna 2a is extended and the hook switch 2e is pressed, a response signal is issued from the portable telephone 10A to the nearest wireless base station to access the control channel C-CH of the wireless base station. . After that, the terminal station 3 is switched to the communication channel S-CH and makes a call.
A call path is formed between the mobile phone 1 and the mobile phone 10A, and a call is made.

The procedure from the incoming call to the call setup executed by the controller (not shown) in the receiver 1 will be described with reference to the flowcharts of FIGS. FIG.
In, the receiver 1 receives and receives an incoming call from the wireless transmission station 35 (step S1). If there is an incoming call, it is checked whether it is a call number to the own device (step S2), and if not, the process returns to step S1 if not.
Then, the process waits for reception, and if it is the calling number of the own device, a message is received (step S3). This message contains the calling telephone number, serial number and other necessary information. Next, it is determined whether or not the main body 2 is hooked off (step S4). If the main body 2 is not hooked off, a bell sound signal is generated, and a bell sound is generated from the speaker 1b (step S5). The received message is stored (step S6), and the message, in particular, the calling telephone number is displayed on the display 1a (step S7). Thereafter, the power of the main body 2 is turned on (step S
8), the process proceeds to step S11 in FIG.

In step S4, if it is determined that the main body 2 is hooked off, in this case, since the power is on and the call is in progress, a silent call (vibration call) is performed so as not to disturb the call. (Step S9) Silence calling is performed until the bell stop switch 1c is operated. When the bell stop switch 1c is pressed, the calling is stopped, and the process proceeds to step S11 in FIG.

In FIG. 5, the receiver 1 operates to access the control channel C-CH given to itself and to receive in synchronization with the clock of the base station (step S1).
1). When the user hooks off the bell ringing from the speaker 1b or automatically hooks off after a predetermined time has elapsed, the main body 2 issues a response signal to the wireless base station (step S12). Next, the communication channel SC designated in response to the instruction of the control channel C-CH.
H, and transmits a response signal, responds to the confirmation signal with the wireless base station (step S13), and sends only the reference number in the stored message data to the wireless base station (step S14). ). In the base station, the message data transferred from the paging terminal 34 is
A search is performed using the serial number from the main body 2, the calling telephone number is read from the message data, and a call setting is made with the calling telephone 31 to establish a communication path. If the line of the communication path is disconnected for some reason, the data is used to repeat the call setting operation. When the call setting is completed, the calling phone 31 and the mobile phone 10A enter a call mode in which a call is started (step S15).

When the receiver 1 receives an incoming call from another telephone during a call, the message is stored in a memory. This incoming call receiving operation is performed completely independently of the call operation of the main body 2.

When the call is completed and the hook is turned on, the controller detects the hook-on (step S1).
6) A command is issued to the main unit 2 to return to the control channel C-CH (step S17). Thereafter, it is searched whether or not an incoming call remains in the message memory (step S1).
8) If there is any remaining call, a ringing tone is generated (step S).
19) The process proceeds to step S12, and the subsequent steps are executed. If it is determined in step S18 that there is no remaining incoming call, the power of the main body 2 is turned off, and standby reception of the incoming call from the wireless transmission station 35 is performed again (step S18).
1).

Conversely, when a call is transmitted from the mobile phone 10A, when the power is turned on, the receiver 1 sets the control channel C-
After search reception of the CH and establishment of synchronous reception, completion of call preparation is notified by a tone signal. When the hook-off is performed, the communication channel is switched to the communication channel S-CH according to the same signal sequence as that of the car telephone, and the call can be transmitted from the dial 2d to the desired telephone.

In the above embodiment, the procedure of the incoming call processing is performed by the controller in the receiver 1.
A power-on command from the receiver 1 (step S
A second controller started in step 8) may be provided so that the execution of step S11 and subsequent steps is performed by the second controller.

[0023]

As described in detail above, the paging mobile phone according to the present invention has the following effects. 1) By providing a radio call receiver exclusively for receiving a call with the main body of the mobile phone, it is possible to realize a wider service area for the incoming call even when the mobile phone has its antenna shortened during standby reception. In other words, by using a wireless call receiver having a wireless zone wider than that of the mobile phone itself to make an incoming call to the mobile phone, it is possible to call over a wider area than in the case of a single mobile phone. 2) Only operate the paging receiver during standby reception,
By turning off the power of the mobile phone, the battery consumption during standby reception can be reduced. As a result, it is possible to use the device for a long time, or to reduce the size of the battery and downsize the telephone itself. 3) Since the mobile phone main unit and the radio call receiver operate separately, it is possible to receive an incoming call from another telephone even during a call. 4) Notify the user if there is any remaining caller information
So, the state of the power-on sent to the originator of the non-originating because one coercive
