Abstract

PURPOSE:To always execute outgoing and incoming, when a radio terminal is speakable by executing the registration from the radio terminal, and using temporarily a radio base equipment as a dedicated equipment of the radio terminal. CONSTITUTION:A radio terminal 12 transmits a special number containing a separate identification number of a radio base equipment for forming a speech path together with the own separate terminal identification number. A central processor 2 which receives this special number rewrites a special number registered in advance to a main storage device 3 from an input/output device 4, to this received special number and registers it. The central processor 2 transmits a group number in a new separate identification number to a radio base device 8 and the radio terminal 12 through a radio base equipment control trunk 6, and sends out a confirmation sound. The radio terminal 12 discriminates its confirmation sound, and thereafter, finishes the registering operation. Accordingly, the radio terminal which executes the registration can execute outgoing and incoming only from the fixed radio base equipment, therefore, it becomes unnecessary that the radio terminal executes unnecessarily a position registering operation.

After confirming the system identification number, the group number assigned in the individual identification number 14 of the wireless base unit 8 is compared with the group number 23 in the individual identification number 17 in its own memory. Send a call to the device.

After confirming the dial tone, the wireless terminal 12 transmits a special number including its own individual terminal identification number and the individual identification number of the wireless base unit forming the communication path. The central processing unit 2 which has received this special number rewrites the special number registered in the main storage device 3 from the input / output device 4 in advance and registers it. The central processing unit 2 receives the radio base unit 8 and the radio terminal 1 via the radio base unit control trunk 6.
The group number in the new individual identification number is transmitted to 2 and a confirmation sound is transmitted. After identifying the confirmation sound, the wireless terminal 12 ends the registration operation.

[Calling] Calling operation will now be described.
The wireless terminal 13 is the individual identification number 1 of the wireless base devices 8 and 9.
However, since the group number 21 of the individual identification number 14 in the wireless base device 8 is different from the group number 24 of the individual terminal identification number 18 in the wireless terminal 13, the individual identification number 15 of the wireless base device 9 is received. Only in its own memory,
The transmission is performed to the wireless base device 9. Similarly, since wireless groups other than the wireless terminal 12 have the same group number set in the individual identification number, the wireless base device 9 can make a call.

The wireless terminal 12 receives the signals of the wireless base devices 8 and 9 similarly to the wireless terminal 13, but the wireless base device 8

Thereafter, the wireless base station 8
Other than the above, the wireless base device 8 can also transmit and receive signals from other than the wireless terminal 12. Further, a timer can be set by an input from the input / output device 4 and an operation in the wireless terminal, and the registration can be canceled after the time is over, that is, a predetermined time has passed, so that it is possible to prevent forgetting the cancel operation. The wireless base device whose registration has been canceled can set a communication path with any wireless terminal in the wireless zone.

[0019]

As described above, according to the present invention, since the registered wireless terminal can make and receive calls only from a fixed wireless base device, the wireless terminal can perform position registration operation unnecessarily. There is no need. Therefore, when the wireless terminal can make a call, it can receive an incoming call without fail, which is effective when waiting for an important incoming call in a place with a large amount of calls.
