Location registration information table 11 for the calling telephone number
If there is information (location area number and wireless base station number) whose location is registered in a, the information is updated, and if it is a new registration, the call telephone number, the call area number and the wireless base station number are updated. To memorize.

In the settlement of the number of connected devices in the process 124,
One is added to the number of connected radio base station numbers corresponding to the location-registered radio base station numbers in the specific area information table 11b. If the location has already been registered, the number of connected radio base station numbers corresponding to the location-registered radio base station numbers is increased. A process of subtracting 1 is performed.

Then, if the authentication response is incorrect in the process 100 (No), if there is no available channel in the process 102 (No), if the permitted number i is 0 in the process 110 (Yes), and in the process 112 When the number j of connected devices is not smaller than the number i of permitted devices (N
o), and if the current time is not within the permitted time in the processing 114 (No), a location registration rejection is transmitted to the wireless base station (130), and the confirmation processing ends.

According to the radio telephone system of the present invention, the radio network controller 1 stores, in the specific area information table 11b, specific area information which is a permission condition for location registration corresponding to a preset radio base station zone. However, when a location registration request is received from the wireless telephone 3, location registration is accepted only when the information matches the specific area information. Therefore, location registration in a specific area can be restricted even in a service area. This has the effect of limiting the outgoing / incoming and incoming calls and avoiding the adverse effects of radio waves.

As a result, in a specific area including, for example, an operating room, an intensive care unit, and a hospital room of a wearer of an electronically controlled medical device such as a pacemaker, the number of permitted vehicles in the permitted conditions is set to zero. Even if a legitimate wireless telephone is used in the system, it is possible to completely prohibit outgoing and incoming calls by rejecting the location etc. recording request on the side of the radio network controller 1 regardless of the user's intention.

Also, for example, by setting a permission time in the permission condition and permitting the location registration only for a time until the light is turned off, a bedridden hospitalized patient can call a family member or a friend from a bed using a wireless telephone. It is also possible to

Also, not only in medical institutions, but also in, for example, concert halls, etc., by prohibiting location registration during a performance, the user of the radiotelephone can be made conscious.
The use of the system under specific conditions can be prohibited, and the user of the wireless telephone can use the system more safely. This has an extremely large effect in terms of the management and operation of the entire system and the service.
