[0016]

Embodiments of the present invention will be described below with reference to the drawings.

The blocks having the same functions as those of the conventional example shown in FIG. 5 will be described with the same reference numerals.

FIG. 1 is a block diagram showing a configuration of a wireless telephone device according to an embodiment of the present invention.

A third control unit 14 provided in the line control station 1 has a restricted access control table in which an ID is registered for each mobile station in a restricted access management table divided for each wireless zone of the base station 4. The point that the station ID storage unit 16 is additionally connected,
It is different from the conventional line control station 1.

The location registration processing in the off-limits wireless zone of the wireless telephone device of the present invention configured as described above will be described with reference to the flowcharts shown in FIGS.

FIG. 2 shows a radio zone 31 of the base station 4 shown in FIG.
2 shows the location registration processing operation on the base station side when the mobile station 5 performs location registration.

First, the second controller 12 in the base station 4
Receives a location registration request signal from the mobile station 5 (S
1) The second control unit 12 extracts the ID of the mobile station 5 from the mobile station ID storage unit 23 and the ID of the local station from the local station ID storage unit 22 and sends the location control request signal together with the location control request signal. (S2). If the second control unit 12 cannot receive the position registration request signal from the mobile station 5 in S1, it repeats S1.

Next, when the mobile station ID mismatch signal is received from the line control station 1, the processing is terminated without performing the position registration of the mobile station 5 (S3). If a location registration completion signal is received from the line control station 1 without receiving a mobile station ID mismatch signal
(S4), the second control unit 12 controls the radio interface 1 between mobile stations.
From 1, a location registration completion signal is sent to the mobile station 5 (S5).
If the location registration completion signal cannot be received in S4, the second
The control unit 12 waits for the input of the entry restriction signal from the line control station 1, and if there is no input, terminates the processing (S6). When the access control signal is received from the line control station 1 in S6, the second control unit 12 sends the LED / LC from the radio interface 11 between mobile stations.
D display signal and warning sound signal are transmitted to the mobile station 5 (S
7), end the location registration process.

FIG. 3 shows a location registration processing operation of the line control station 1 when a location registration request is received from the base station 4.

First, if the third control unit 14 does not receive a location registration request signal from the base station 4 (S8), the third control unit 14 repeats S8. When the third control unit 14 receives the mobile station ID and the position registration request signal from the base station 4, the third control unit 14 checks the mobile station ID registered in the registered mobile station ID storage unit 15 to determine whether the mobile station ID is a mobile station ID. A comparison is made with the received mobile station ID (S9). In step S9, the comparison result is determined, and if no ID mismatch is detected, the third control unit 14 sends a mobile station ID mismatch signal from the communication unit 19 to the base station 4 (S10), and ends the process. If a match between the IDs is detected in S9, the base station 4 registered in the mobile station ID and off-limits mobile station ID storage unit 16 is detected.
Is compared with the mobile station ID in the entry exclusion management table (S1).
1). If the IDs match, the third control unit 14 communicates with the communication unit 19
The access restriction signal is transmitted to the base station 4 (S12). Also,
If no ID match is detected in S11, the third control unit
14 registers the ID of the mobile station 5 in the location management table of the base station 4 registered in the location registration management unit 17 (S13). Next, the third control unit 14 transmits a position registration completion signal from the communication unit 19 to the base station 4 (S14), and ends the position registration processing of the line control station 1.

The method of registering the mobile station ID in the off-limits management table of the off-limits mobile station ID storage unit 16 is as follows. When a mobile station number prohibited from entering the mobile station is input, the third control unit 14 stores the ID of the base station input from the operation unit 30 from the base station ID storage unit 18 into the entry-inhibited mobile station ID storage unit 16. Stored in the off-limits management table,
Next, the mobile station ID input from the operation unit 30 is stored from the registered mobile station ID storage unit 15 to the off-limits mobile station ID storage unit 16 in association with the base station ID.

The operation of the wireless telephone device of the present invention configured as described above in the off-limits wireless zone will be described with reference to FIG.

As shown in FIG. 4, when the mobile station 5 moves from the wireless zone 31 of the base station 4 to the wireless zone 31 'of the base station 4' where entry of the mobile station 5 is prohibited and requests location registration, The line control station 1 transmits an access restriction signal to the base station 4 'via the extension 3, and the base station 4' receives the signal to
Send an LCD display signal and a warning sound signal to the mobile station 5. Upon receiving the LED / LCD display signal and the warning sound signal from the base station 4 ', the mobile station 5 displays an off-limits display from the display unit 29 of FIG. 1 and emits a warning sound from the receiver 27 indicating that it is off-limits.

In the present invention, it goes without saying that a conventional wireless location registration method can also be used. Also,
The mobile station connected to the base station may be single or plural.

[0030]

As described above, the radio telephone apparatus of the present invention is provided with an off-limit mobile station ID storage unit in the line control station for restricting access to the base station in the radio zone. When the mobile station stored in the storage unit moves to the off-limits wireless zone and starts location registration, the line control station confirms the mobile station in authentication and transmits the authentication result to the base station. The warning signal is transmitted to the mobile station, and the mobile station can receive a warning signal and display a warning sound. Therefore, it is necessary to control the mobile station's movement regulations and to inform the mobile station of entry restrictions for precise maintenance in offices, factories, and other business establishments, and information on bans from entering the wireless zone where entry is dangerous due to disasters in the public. Becomes possible.
