When a mobile communication subscriber newly registers in the mobile communication network, the home memory station closest to the wireless area normally used by the subscriber is determined as the home memory station of the subscriber, and the home memory station is assigned to the home memory station. The subscriber data of the subscriber, that is, what kind of service the subscriber has subscribed to (for example, call waiting service), billing information, type of the mobile device, class (indicating maximum transmission output, etc.) , Registered position information and the like are stored.

[0004] When the mobile unit 15 has a location registration area 16 ₁ to 1
Moving to 6 _2, compares the location registration area number in the broadcast information broadcast from the base station in the area 16 in _2, and a location registration area number stored in the mobile station 15 becomes a mismatch, a new position It recognizes that it has entered the registration area 16 _2, mobile station 15 transmits a location registration signal to the base station. The switching center having received the home memory station of the mobile device, for example by sending to 15 _1, and updates the location information in the subscriber data. When an incoming call is made to the subscriber of the mobile station 15, the registered location information is obtained by referring to the subscriber data in the home memory station from the mobile subscriber number (telephone number), and the location registration is performed. Area 1
Simultaneously paging signal for that mobile subscriber from all base stations 12 _{5-12 8} 6 within ₂ against all its wireless area 11 ₅ to 15 ₈ is transmitted. When a mobile communication subscriber makes a call, the exchange which has received a signal from the mobile station via the base station determines whether the mobile communication subscriber may be permitted to make the call. And performs connection control and the like based on the subscriber data of the home memory station.

In the past, the home memory station of a mobile communication subscriber was fixed at the station determined at the time of first registration, unless his home memory station canceled the subscription to the mobile communication network. Also, the subscriber number (telephone number) of a mobile communication subscriber was partly assigned to specify the location of the subscriber's home memory station.

[0006]

Conventionally, even if a mobile communication subscriber wants to change his subscriber number (telephone number), he or she can only change it to a telephone number that can access the first registered home memory station. Was. That is, it is necessary that a part of the changed telephone number includes the number indicating the location of the home memory station registered first, and the user could not arbitrarily select and change the telephone number.

[0007] Conventionally, in order to change its own home memory station, it is necessary to change the telephone number of the mobile communication subscriber, and there is a drawback that the convenience of the service for the user is reduced.

[0008]

According to the first aspect of the present invention,
Stores subscriber data for each mobile communication subscriber
Address memory station that stores home memory station addresses
The switching center accesses the subscriber data of the mobile communication subscriber.
When accessing, first access the address memory station,
The address of the home memory station that stores the subscriber data
Address, and then use the address to learn the home
Subscriber data by accessing Mori station
Access the data. According to the second aspect of the present invention, an address memory station for storing an address of a home memory station storing the subscriber is provided for each mobile communication subscriber, and a location registration signal is transmitted from the mobile communication subscriber via the base station. The receiving exchange accesses the address memory office, finds out the home memory office address storing the subscriber data of the mobile communication subscriber, stores the address in the address memory of the own exchange, and thereafter, When it becomes necessary to refer to the subscriber data of the mobile communication subscriber, the address memory in the own station is searched to find its home memory station address, and the subscriber data of the mobile communication subscriber is stored at that address. To access the home memory station.

[0009]

According to this configuration, the address of the home memory station storing the subscriber data and the telephone number can be separated as independent ones, and the remote address memory station is accessed before accessing the home memory station. No need to access.

[0010]

FIG. 1 shows an example of the configuration of a mobile communication system to which the present invention is applied, and portions corresponding to those in FIG. 3 are denoted by the same reference numerals. In the present invention, an address memory station 21 is provided and connected to the signal network 14. This address memory station 21
For example, as shown in FIG. 2A, each telephone number (mobile communication subscriber number) is associated with an address of a home memory station that stores the subscriber data of the subscriber.

The mobile unit 15 passes between the location registration areas,
We recognize this and transmits a location registration signal 22 as shown in FIG. 2B in the base station 12 _5, the switching station 13 ₃ receives via the base station 12 ₅ this switching station 13 ₃ location registration signal 22 The telephone number of the mobile device 15 inserted in the address is inserted into the address request signal 23 and transmitted to the address memory station 21. Address memory station 21 that receives the address request signal 23 searches the home memory station address corresponding to the telephone number in the signal 23, the address to the address confirmation signal 24 inserted to the requesting switching center 13 ₃ I will send it back. The switching station 13 ₃ which has received the address confirmation signal 24 and the telephone number in the address memory 25 of the local station, storing the home memory station address as pairs as in FIG. 2A.

[0012] In Thereafter, the switching station 13 ₃ mobile device 1
5 Upon reception of the calling signal from, know the home memory station address by searching the address memory 25 of the local station in the telephone signal, with respect to the home memory station 17 ₁ of the address, sends a read request signal 26, the home switching center 13 ₃ those reads subscriber data from the memory station 17 ₁ corresponding to the telephone number received. That is, exchange 1
3 _3, access to subscriber data of the mobile communications subscriber 11
To access the address memory station 21 first,
Home memory station 17 ₁ storing the subscriber data
Knows the address of the home memory and uses that address
Station 17 _{1 is} being accessed.

The address memory station 21 registers and stores the telephone number and the address of the home memory station when the mobile communication subscriber subscribes. The wireless area normally used in such transfer becomes farther from the home memory station 17 ₁ own subscriber data is stored, if Near the home memory station 17 _2, the home memory station 17 has become far ₁ is transferred to the nearby home memory station 17 ₂ , the subscriber data in the home memory station 17 ₁ is deleted, and the address memory station 2 is deleted.
The home memory station address for the telephone number in 1 rewrites to those for the home memory station 17 _2.
In this way, since the home memory station is closer, the time for occupying the signal line equipment for subscriber data is shortened, and the effective use of the signal line equipment is achieved.

[0014]

As described above, according to the present invention, by providing the address memory station 21, the telephone number,
The home memory station address can be determined independently of each other, so that the user can obtain any telephone number without being bound by the home memory station address.

Further, when the home memory station is moved away due to relocation or the like, the home memory station can be changed to a home memory station close to the home memory station without changing the telephone case. As shown in FIG. 4, every time subscriber data is required at the exchange according to a signal 28 from the mobile station, an address request signal 29 in which the telephone number is inserted is transmitted to the address memory station 21.
The above-described efficiency can be obtained even if the address memory station 21 returns the address confirmation signal 30 including the home memory station address corresponding to the telephone number and accesses the home memory station using the address. In this case, however, it is necessary to send and receive the address request signal 29 and the address confirmation signal 30 to and from the address memory station 21 each time the subscriber data is required. Signal 23 to station 21,
24, the home memory station address can be known from the address memory 25 in the own station until the next location registration is performed. In other words, the access to the address memory station 21 is not required, and the processing can be simplified accordingly. Become
In addition, the time for using the signal line equipment is reduced, and the signal line equipment can be used more effectively.
