Other than voice calls, a user who wants to use a mobile station can stop the mobile station from staying in a special base station (standby) by operating the mobile station function key and stay in a normal base station that covers the area. Give instructions to (standby). The mobile station reports the area characteristic code received until immediately before to the normal base station when the normal base station is located (standby). The normal base station (upper station) recognizes that the corresponding mobile station (for example, mobile phone MS1) is located in the special area, and records the mobile station number of this mobile station in association with the area characteristic code. . When an incoming / outgoing call from a mobile station occurs, the normal operation station (upper station) determines whether to permit the service based on the area characteristic code of the mobile station. If so, provide the service. If it is not permitted, the service will not be provided.

Next, embodiments of the present invention will be described in detail with reference to the drawings.
The special base station BS2 determines whether or not it has received a location registration request from a mobile station (at least one mobile phone such as MS1, MS2) (step S00). When the special base station BS2 receives the location registration request, the location registration of the mobile station is performed (step S01). When a request other than location registration is received from the mobile station, the request from this mobile station is rejected (step S02). Then, the reason for refusal is notified to the mobile station (step S03).
The normal base station BS1 determines whether there is a call from the mobile station (for example, MS1) or an incoming call to the mobile station (step S10). When a call from the mobile station MS1 or an incoming call to the mobile station occurs, the presence / absence of registration of the area characteristic code of the mobile station corresponding to the telephone number of the mobile station is searched (step S11). If the area characteristic code is not registered, outgoing or incoming connection is made (step S19). If the area characteristic code is registered, it is searched whether the outgoing / incoming service is possible (possible) or not (impossible) in the corresponding area (step S13). If the outgoing / incoming service in the area is permitted, outgoing or incoming call connection is performed (step S19). If the outgoing or incoming call service in the area is not permitted, the outgoing or incoming call connection is not performed (step S15). If it is a mobile station transmission request, the source mobile station is notified of the reason why the transmission cannot be made (20). If it is a mobile station incoming call request, the reason why the incoming call cannot be made is notified to the caller (step S17). The source information is notified to the destination mobile station (step S18).

<Operation of Example>
Next, the operation of this embodiment will be described using specific examples.
As shown in FIG. 2, a train runs in the service area A1 of the normal base station BS1, and description will be made taking the inside of the regulation area A2 in this area as an example. The use of a mobile phone in a train is self-restricted (for example, turning off the power of the mobile phone). Is a problem. Therefore, a special base station BS2 that covers the train area A2 is installed. Since the base station BS2 is not connected to the host station, it can move with the train. As shown in FIG. 3, the base station BS2 notifies an area characteristic code “3: the area is a library, train or bus” indicating a train area. As shown in FIG. 2, when the mobile stations MS2 and MS3 enter the train, the broadcast information of the base station BS2 is received and a location registration request is transmitted to the base station BS2. Base station BS2 causes mobile stations (mobile phones) MS2 and MS3 to be present (standby). When there is a transmission request from the mobile stations MS2 and MS3, the base station BS2 rejects the transmission request from the mobile stations MS2 and MS3 and notifies the mobile station of the reason for rejection. The mobile station displays the reason for rejection and informs the user. The mobile stations MS2 and MS3 cannot make a call and continue to the base station BS2 (standby). Since the base station BS2 is not connected to the upper station, it does not provide an incoming service to the radio stations MS2 and MS3.

  Therefore, the mobile stations MS2 and MS3 cannot make or receive calls. Even if the user of the mobile station MS2 is on board, the user who wants to use the mobile communication service that does not harm the surrounding environment (email transmission, incoming mail without ringing the incoming call buzzer, browsing the Internet) can use the function key operation of the mobile station MS2. The mobile station MS2 is instructed to stop being in the base station BS2 and to be in the other base station (standby). The mobile station MS2 catches the radio waves of the normal base station BS1 covering the area, requests location registration from the base station BS1, and reports the area characteristic code “3” to the base station BS1. Base station BS1 makes mobile station MS2 reach (standby). From the area characteristic code “3” of the mobile station MS2, the base station BS1 recognizes that the mobile station MS2 is located on the train (either in the library, train or bus), and the corresponding mobile station as shown in FIG. Record the number and area characteristic code in association. When the mobile station MS2 makes or receives a call, the base station BS1 recognizes the service type and refers to the permitted / non-permitted service list for each area characteristic code as shown in FIG. To decide. In the above example, since the area characteristic code of the mobile station MS2 is 3, the base station BS1 does not provide the mobile station MS2 with voice call transmission, voice call reception, incoming call buzzer ringing service, mail transmission, It is decided to provide an incoming mail service for the Internet and no incoming call buzzer.

  When the mobile station MS2 leaves the train area whose area characteristic code is 3, the mobile station MS2 is automatically registered by position registration periodically registered or by turning the mobile station power OFF → ON. The location is registered again. The base station BS1 receives the location registration without the area characteristic code from the mobile station MS2, and deletes the area characteristic code record of the mobile station MS2 from the table of FIG. By doing so, the base station BS1 provides full service to the mobile station MS2. As described above, in the present invention, when the mobile station MS3 leaves the train area whose area characteristic code is 3, the mobile station MS3 is automatically located (standby) from the base station BS2 to the base station BS1 by periodic location registration. The full service can be used.

  In the above-described embodiment, the case where the characteristic area code is 3 has been described as an example. However, even when the characteristic area code is 1 or 2, it is a matter of course that the present invention may be used. The only difference is that when the characteristic area code is 1 or 2, there is a difference that the regulation of the service is performed according to FIG. In the present invention, an area characteristic code is notified to a mobile station (mobile terminal) located in a special area of the special base station BS2 (an area where at least a part of the communication service to the mobile terminal is restricted). Restrict communication services according to the code. This area characteristic code is managed by the normal base station BS1 or the base station control station BSC which is a higher station of the special base station BS2. Also, since the special base station BS2 is stand-alone, it is basically impossible to provide outgoing and incoming services, so the mobile portable terminals MS2 and MS3 are limited in communication services based on the notified characteristic area code. It will be. Also, under such restrictions, if the mobile station MS2 that has received the characteristic area code wants to communicate without being restricted by communication based on the characteristic area code if a certain special situation occurs, Press a special key of this mobile station MS2, or press a numeric key (eg numeric key 6) or a function key for a certain period of time, for example, to stop the base station (special base station) currently used It is also possible to add a function to the mobile station so that the mobile station cancels that it is under the control of this base station and changes the management to an adjacent or other management base station. .

  In this system, in an emergency such as an earthquake or an emergency such as the occurrence of a sudden illness, the mobile stations MS2, MS3, etc. are stopped from the restriction based on the restricted area characteristic code to perform normal communication. It is possible to return to the service, or relax the current limited service to provide a limited service offer that is looser than the current one. For this reason, for example, in the table showing the definition example of the area characteristic code shown in FIG. 3, when the area column is hospital, the area characteristic code is 1, but the contents of the emergency or emergency In consideration of the above, a threshold value is provided, and the area characteristic code is incremented by 1 or 2 according to the threshold value (for example, when the area characteristic code exceeds 3, the service returns to the normal service). You can also. For example, in the table showing the definition example of the area characteristic code shown in FIG. 3, as the threshold value 1 on the right side of the area characteristic code column, the area characteristic code is all plus 1 in the emergency situation (in the case of the absence of a sick person, etc.) 2 for hospitals, 3 for theaters and lectures, and 4 for public facilities such as libraries, trains, buses, etc. In addition, emergencies (such as the occurrence of illegal illegal jacking or illegal hijacking, earthquakes, etc.) In the case of natural disasters, etc.), the threshold value is 2, the area characteristic code is all plus 2, the area is 3 for hospitals, 4 for theaters and lectures, and 5 for public facilities such as libraries, trains, and buses. However, as described above, when the area characteristic code exceeds 3, it can be set to “return to normal service.” In such a situation, the situation Accordingly, the restriction of the service can be relaxed, or the restriction can be relaxed so as to provide a normal service. Step S31 for confirming whether or not there is a threshold value and Step S32 for determining whether or not the threshold value is 1 are provided. If there is no threshold value in Step S31 (No in Step S31), the process proceeds to Step S13 described above. If there is (Yes in Step S31), the process proceeds to Step S32. Then, in Step S32, if the threshold is 1 (Yes in Step S32), the value of the area characteristic code in FIG. If the area characteristic code plus 1 is applied and the threshold is not 1 (No in step S32), the area characteristic code shown in FIG. The area characteristic code plus 1 can be applied to the code value, and the subsequent flow is the same as that in step S14 and subsequent steps, and the description thereof is omitted. The relaxation of the restriction is similarly applied to other embodiments described below.

<Other embodiments>
In the above-described embodiment, the area characteristic code may be managed by an upper station of the base station. The service type may be a case of handover other than transmission and reception.

  ADVANTAGE OF THE INVENTION According to this invention, the function of the mobile station located in a special area can be stopped. At the same time, it is possible to provide a service that does not harm the surrounding environment to users who want to use mobile stations. Since the special base station is not connected to the host device, it can be easily installed in places such as trains and buses.
