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.

Conventionally, the home memory station of a mobile communication subscriber is fixed to the station determined at the time of first registration unless the home memory station of the mobile communication subscriber cancels 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]

The subscriber data stored in the home memory station is referred to from the exchange every time a call is transmitted and received. If the wireless area to be used moves to a far away place different from the one at the time of the subscription contract, the exchange that continuously accepts outgoing and incoming calls of the mobile device after moving will refer to the subscriber data to the home memory station far away from the wireless area Therefore, it is necessary to perform signal transmission / reception, so that the occupation time of the signal line equipment is long, the effective use of the signal line equipment cannot be achieved, and there is a disadvantage that a connection delay at the time of transmission / reception is increased.

[0007]

According to the present invention, a location registration memory for storing location registration information from a mobile station, and a home memory for storing a home memory station number storing subscriber data for each mobile station. A station memory, a network configuration data storage memory for storing a location registration area in a mobile network and a home memory station installation location, and a processing station comprising a control unit are connected to a signal network, and receive location registration information from a mobile device. The location registration area number received together with the date and time of reception is recorded in the location registration memory, and the location registration information of the mobile station at a certain time is read out from the location registration memory, and the mobile station within the certain time is the longest. The long-term stay location registration area where the user was staying is obtained, and the latest home memory station number closest to the long-term stay location registration area is determined from the network configuration data in the network configuration data storage memory. Retrieved from Mumemori station memory, the current home memory station number subscriber data of the mobile station is actually stored at the moment to find the home memory station memory or <br/> et al, the recent home memory station number and the Comparing the current home memory station number with the current home memory station number, and if the numbers are different, replacing the current home memory station number with the latest home memory station number; The number of the home memory station storing the subscriber data is changed by instructing the home memory station of the number to transfer the subscriber data of the mobile station.

[0008]

[Action] As such is the configuration, the location registration area of the mobile station processing station is constantly monitored, if you move to another location registration area to stay for not long time from a conventional location registration area, automatically The home memory station storing the subscriber data is changed to the home memory station closest to the destination area, and the operation is performed so that the signal line equipment is always wasted and the connection delay at the time of transmission / reception is minimized.

[0009]

FIG. 1 shows a mobile communication network to which the present invention is applied, and portions corresponding to those in FIG. 4 are denoted by the same reference numerals. In the present invention, a processing station 21 is connected to the signal network 14. Processing station 2
1 is a location registration memory 22 for storing location registration information from the mobile device, a home memory station memory 23 for storing a home memory station number storing subscriber data for each mobile device (mobile communication subscriber), It comprises a network configuration data storage memory 24 for storing the location registration area in the mobile network and the nearest home memory station installation location, and a control unit 25.

As shown in FIG. 2A, the location registration memory 22 has a storage area for each mobile unit (mobile communication subscriber), and each time location registration information is received from the mobile unit, the location registration information received together with the date and time of reception is received. The area number is sequentially recorded in the storage area of the mobile station number. As shown in FIG. 2B, the home memory station memory 23 records the number of the home memory station in which the subscriber data corresponding to the mobile station number is stored. As shown in FIG. 2C, the network configuration data storage memory 24 stores the nearest home memory station number corresponding to each location registration area number.

The control section 25 operates as shown in FIG.
That is, the control unit 25 reads out all the location registration information corresponding to the mobile station number n from the location registration memory 22 at a relatively long fixed time period such as several months (S ₁ ), and after the reading is completed, the mobile station number n to clear all location registration information corresponding to the (S _2). The control unit 25 calculates the stay time for each position registration area number from the read position registration information, using the recorded date and time as a clue. And recording the longest stay location registration area number A (S _3).
Thereafter, the mobile station number n is read from the home memory station memory 23.
The home memory station number B (current home memory station number) corresponding to the long-term stay position registration area number A is read from the network configuration data storage memory 24 (S ₄ ). station number) read out (S _5). Here, the home memory station number b is
The home memory station number closest to the mobile station at the present time is estimated, and the home memory station number B is estimated to be the home memory station closest to the mobile station before this processing.

Thereafter, the numbers B and b are compared (S ₆ ), and if they are equal, it is determined that the mobile station has not moved from the location registration area before this processing, and the processing is terminated. If the numbers B and b are different, it is determined that the mobile station has moved to the main location registration area, and the home memory station number of the mobile station number n in the home memory station memory 23 is changed from B to b. rewritten to (S _7). At the same time, the home memory station of the home memory station number B is instructed to transfer the subscriber data of the mobile station number n to the home memory station of the home memory station number b, and the process ends (S ₈ ).

The control unit 25 repeats the above-described processing at regular time intervals while incrementing the mobile station number by one, and constantly updates the home memory station storing the subscriber data for all the mobile stations. It is not preferable to update the home memory station too frequently because the processing becomes complicated and the maintenance of the home memory station becomes complicated.It is preferable to update the home memory station every several months corresponding to the move of the subscriber or the long-term business trip. .

When a signal is transmitted from the mobile station 15 to the exchange via the base station, and it is determined from the signal that the subscriber data is required, the exchange sends the processing station 21 with the mobile station. When the processing station 21 receives the request signal, the mobile station number in the signal is searched for the home memory station number, and the obtained home memory station number is entered. The inserted address confirmation signal is returned to the requesting exchange. The exchange which has received this confirmation signal accesses the home memory station of the home memory station number in the signal and refers to or updates the subscriber data of the mobile station.

[0015]

As described above, according to the present invention, the home memory station is instructed to the home memory station closest to the communication area of the subscriber in accordance with the subscriber's relocation or long-term business trip. The data is stored automatically. As a result, a signal network is used to access the home memory station every time a mobile station makes and receives a call. However, the use of the shortest distance signal line is sufficient, and efficient use of signal network equipment can be realized. In addition, it is possible to minimize connection delay at the time of outgoing / incoming calls.

Further, the subscriber data is updated by the maintenance person when the service conditions are changed by the subscriber declaration, and in the billing process, monthly billing data is read and billing is performed. These daily maintenance
The operation processing can also be performed more efficiently if the home memory station is close to the subscriber.
