BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a radio telephone apparatus according to an embodiment of the present invention. In the block diagram of FIG. 1, reference numeral 1 denotes an automatic transfer registration unit which uses a transfer service in a wireless telephone service network and requests a cordless telephone to transfer an incoming call to the wireless telephone service network, and 2 cancels the transfer request. An operation unit 3, a receiver 4, a transmitter 5, an antenna 6, a cordless wireless unit 7 as a first wireless communication function, a cellular wireless unit 8 as a second wireless communication function, The unit 9 and the control unit 10 are the same as those of the related art. Reference numeral 11 denotes an apparatus main body including blocks 1 to 10.

The operation of the wireless telephone device having the above components will be described below. As shown in the schematic diagram of the telephone network in FIG. 3, the wireless telephone service network has a wide service range, and the usable range of the cordless telephone occupies only a small part of the service range. Therefore, the user of the wireless telephone device normally uses the wireless telephone service network, and when a call is received, the incoming call information is transmitted to the antenna 6.
, Wireless communication is performed by the cellular wireless unit 8, and the control unit 10 and the operation unit 3 perform call processing to start a call with the caller.

On the other hand, the apparatus main body 11 detects whether or not it has entered the usable range of the cordless telephone. For this purpose, the apparatus main body 11 exchanges an ID code with the base unit 29 of the cordless telephone. As a method, first, the control unit 10 of the apparatus main body, which is a slave unit, periodically controls the cordless wireless unit 7.
Sends an ID code request from the antenna 6 to the master via the antenna 6, and the master sends an ID code in response to the request,
This is received via the antenna 6 and the cordless radio unit 7 and detected by the detecting unit 9 to detect that the cordless telephone has entered the usable range. Alternatively, the ID code is transmitted continuously or periodically at a short cycle from the master unit, and the slave unit receives the ID code continuously or periodically at a longer cycle than the master unit. A method may be adopted in which the timing is set such that the master unit transmits during reception. When the detection unit 9 detects that the user has entered the usable range of the cordless telephone, the detection unit 9 outputs an automatic transfer registration request signal to the automatic transfer registration unit 1 and receives the automatic transfer registration request signal. The automatic transfer registration unit 1 issues a transfer request to the wireless telephone service network via the control unit 10, the cellular wireless unit 8, and the antenna 6 so that an incoming call to the wireless telephone service network side is transferred to the cordless telephone side.

In this way, the incoming call to the wireless telephone service network side can be made without the user switching to the cordless telephone in advance, and the transfer means 21 of the mobile telephone exchange 20 can be provided.
The call is automatically transferred to the cordless telephone side, and the call charge for incoming calls becomes unnecessary. On the other hand, when the detection unit 9 detects that the user has gone out of the cordless telephone usable range, the detection unit 9 outputs an automatic transfer release request signal to the automatic transfer release unit 2 and receives the automatic transfer release request signal. The automatic transfer canceling unit 2 requests the wireless telephone service network via the control unit 10, the cellular wireless unit 8 and the antenna 6 to cancel the transfer of the incoming call to the wireless telephone service network side to the cordless telephone side. A normal wireless call is made within the transfer means 21 of the telephone exchange 20.

In this manner, an incoming call to the wireless telephone service network side is automatically made depending on whether the user is within the cordless telephone usable range or out of the range, or the wireless terminal of the cordless telephone or the wireless terminal. Transferred to the telephone service network side.

The operation of each unit is controlled by the control unit 1 as illustrated.
0 may be used for comprehensive control, or the function of the control unit 10 may be dispersed in each unit, and each may control another unit.
