1 and a communication network 10 including a storage device 13 connected to the exchange 11, one or more base stations 30 connected to the exchange 11 via an access line 20, and a dedicated line 40 to the base station 30. It comprises one or more small base stations 50 connected thereto, and one or more mobile devices 70 connected to the small base stations 50 via a wireless line 60.

The base station 30 includes means for periodically transmitting a notification signal A for notifying the location registration area information and a notification signal B for notifying the location registration acceptance information to the small base station 50. Includes means for periodically transmitting the notification signal A to the mobile device 70. The mobile device 70 receives the notification signal A and stores the contents of the location registration area information included in the received notification signal A. Means for transmitting a location registration request signal to the small base station 50 when the information differs from the information being transmitted, and the small base station 50 transmits the location registration request signal transmitted by the mobile station 70 to the base station 30. The communication network 10 includes a storage device 13 in the communication network 10 based on the location registration request signal received by the base station 30.
A registration unit 12 in the exchange 11 is provided as a unit for registering the location of the mobile station 70.

As described above, according to the first embodiment, the small base station 50 receives the position registration request from the mobile station 70 under the control of the notification signal A and the notification signal B notified from the base station 30. A control function 51 for limiting the
When the notification signal B has information for restricting the reception of the location registration, the control function 51 notifies the mobile station 70 of the notification signal C for restricting the location registration request to the mobile station 70 at any time. However, when the mobile station 70 receives the notification signal C, the mobile station 70 has a means for stopping the transmission of the location registration request signal, so that the location registration request can be made without increasing the communication load between the base station 30 and the small base station 50. Is to limit.

Next, the operation of the first embodiment will be described with reference to FIGS. The base station 30 periodically sends a notification signal A for notifying the location registration area information and a notification signal B for notifying the location registration acceptance information to the small base station 50 (step ST2-1). The small base station 50 periodically sends out the notification signal A to the mobile device 70 (step ST3-1). The mobile device 70 receives the notification signal A (step ST4-1), determines whether or not the content of the location registration area information included in the received notification signal is different from the stored location registration area information. Sends a position registration request signal to the small base station 50 (step ST4-2).

When receiving the location registration request signal from mobile device 70 (step ST3-2), small base station 50 transmits a location registration acceptance signal to mobile device 70 (step ST3-3). Here, the small base station 50 has the control function 5
If it is determined in step 1 that the reception of the location registration is permitted with reference to the notification signal B (step ST3-4), a location registration notification signal is transmitted to the base station 30 (step ST3-6). Upon receiving the location registration notification signal, the base station 30 requests the exchange 11 to perform location registration of the mobile station 70 in the storage device 13 in the communication network 10 (step ST2).
-2) The exchange 11 registers the location of the mobile device 70 in the storage device 13 by the registration means 12.

When the small base station 50 determines in the control function 51 that the reception of the location registration has been rejected with reference to the notification signal B, the small base station 50 restricts the location registration request to the mobile station 70. The notification is made by the notification signal C (step ST3-5). The mobile device 70 determines whether or not the location registration acceptance signal has been received (step ST4-3), and if YES, determines whether or not the notification signal C for restricting the location registration request has been received (step ST4-4). If the answer is YES, the location registration request is stopped (step ST4-5).

It is determined that the reception of the location registration is refused by receiving a notification signal B periodically transmitted from the base station 30 after the small base station receives the location registration request from the mobile station 70 for a certain period of time. In the case of rejection, control is performed so that the notification signal C is transmitted.

According to the first embodiment, among the cases where concentration of location registration requests is a particular problem, for example, in the case of a station area, when a train arrives during a commuting rush, the location registration request is temporarily stopped. However, except for this temporary peak, location registration requests are relatively leveled out.Therefore, location registration requests from mobile devices are checked, and location registration requests are restricted only during this temporary peak. For example, the above-mentioned problems of the prior art can be almost avoided.

Also, for example, when a train arrives during a commuting rush in the vicinity of a station, a location registration request is temporarily flooded. Since the location registration area is composed of zones covered by multiple base stations including base stations installed in the area adjacent to the station, location registration via base station devices installed in and around the station premises Even if it is restricted during concentration, many of the mobile device owners get off the train, and as soon as they pass through the station premises and surroundings, they spread to the neighboring well-known area, so they can register their location there, It does not affect the service at the time of the actual incoming call except for the area passing through the vicinity.
