BACKGROUND OF THE INVENTION This invention is used in the mobile communication system of the cellular system, about how to access the home memory station for switching center viewing and updating the subscriber data of the mobile communications subscriber.

[0002]

BACKGROUND ART cellular mobile communication system typically has a network configuration as shown in FIG. 4, for example, the service area is divided into a plurality of wireless areas 11 ₁ to 11 _8, these wireless areas 11 ₁ to 11 ₈ to base stations 12 _{1 to} 12 ₈ respectively.
Is provided, the base station 12 ₁ and 12 ₂ are connected to the exchange 13 _1, the base station 12 ₃ and 12 _4, 12 ₅ and 1
2 _6, 12 ₇ and 12 _8, respectively switching station 13 _2, 13
_3, 13 is connected to the _4, switching station _131-134 is connected to the signaling network 14. Range each of the radio signal from the base station 12 ₁ to 12 ₈ can communicate reach the mobile station 15, respectively are in each wireless area 11 ₁ to 12 _8. A plurality of wireless areas 11 in close proximity to each other ₁ to 11 _4, 11 ₅ to 1
Location registration Each area 16 _1, 16 ₂ is constituted by 1 ₈ for each of these location areas 16 _1, 16 _2, respectively home memory station 17 _1, 17 ₂ is a signaling network 1
4 is provided.

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, ie, what kind of service the subscriber has subscribed to (for example, an incoming call service), billing information, type of the mobile device, class (maximum transmission output, etc.) ), Registered location information, and the like.

[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 17 _1, and updates the location information in the subscriber data. When receiving a call to the subscriber of the mobile device 15, the mobile communication subscriber number (telephone number)
Determined by referring to the position information registered by the subscriber data in the home memory station 17 ₁ from all wireless areas 11 from all base stations 12 _{5-12 8} of that location area 16 within ₂ simultaneously paging signal to the mobile communication subscriber is transmitted to the _{5-15 8.}
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]

Conventionally, even if a mobile communication subscriber wants to change his subscriber number (telephone number), he can only change it to a telephone number that can access the first registered home memory station. Did not. 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 present invention, an address memory station for storing the address of a home memory station storing subscriber data is provided for each mobile communication subscriber, and the exchange office is provided with a mobile communication subscriber. When it becomes necessary to refer to the subscriber data, the address memory station is accessed, and the address memory station searches for the address of the home memory station storing the subscriber data, and further uses the searched address. By accessing the home memory station, desired subscriber data is obtained and transferred to the requesting exchange.

[0009]

With this configuration, the address of the home memory station storing the subscriber data and the telephone number can be separated as independent ones.

[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. 4 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. The address memory station 21 is provided with an address memory 22. As shown in FIG. 2, the address memory 22 stores, for each telephone number assigned to the mobile station, an address of a home memory station for storing subscriber data of the mobile station. It is remembered. The address memory station 21 sends and receives signals to and from the switching station 13 or the home memory station 17 by using the signaling device 23. The control unit 24 controls each unit.

[0011] from the mobile station 15, for example, signal to the exchange 13 ₁ is transmitted through the base station 12 _1, the necessary switching center 13 ₁ refers or updates the subscriber data of the call processing on the mobile station 15 occurs, switching center 13 ₁ transmits a subscriber data access request signal to insert the telephone number to which the mobile station to the address memory station 21 has been inserted into the transmitted signal.

The signaling device 23 of the address memory station 21 receives the subscriber data access request signal, and notifies the control device 24 of this. The control device 24 searches the address memory 22 using the telephone number inserted in the signal, and obtains the address of the home memory station storing the subscriber data of the mobile station 15 corresponding to the telephone number. Controller 24 based on the address search, edit the access request signal related to the subscriber data of the mobile station 15, requesting to transmit the signal to the home memory station 17 ₁ to the signal device 23.

[0013] home memory station 17 ₁ which has received the access request signal reads out the subscriber data from the subscriber telephone number in the signal, and returns the subscriber data to the address memory station 21 as an access response signal. The access response signal address memory station 21 which has received the transferred as access response signal that subscriber data to the requesting switching center 13 _1.

[0014] Replace the home memory station 17 ₁ in this embodiment, as a method for transferring subscriber data to the subscriber exchange station 13 ₁ of the access source data, it is via the address memory station 21 from the home memory station 17 ₁ An example in which the data is transferred to the station 13 ₁ is shown, but there is also a method in which the data is transferred directly from the home memory station 17 ₁ to the exchange 13 ₁ . FIG. 3B shows a subscriber data access control sequence in this case. When applying this method, the access request signal transmitted from the address memory station 21 to the home memory station 17 _1,
It is necessary to insert the address of the switching station 13 ₁ of the access requestor. However, no matter which method is used, the effect of the present invention is not affected.

In the above example, as an example of the configuration of the address memory 22, an example in which a home memory station address is stored for each telephone number assigned to a mobile device has been described. However, information that can identify each mobile device is provided. For example, a mobile device number or the like may be used instead of a telephone number. Further, as the home memory station address, any information may be used as long as the address memory station 21 can identify the home memory station for transmitting the access request signal relating to the subscriber data.

[0016]

As described above, according to the present invention, by providing the address memory station for storing the correspondence between the telephone number and the address of the home memory station, the address memory station can store the subscriber data independently of the address of the home memory station. Any phone number can be selected and changed to any phone number. Further, the home memory station storing the subscriber data and the telephone number can be easily changed by changing the correspondence between the telephone number stored in the address memory station and the home memory station address. Therefore, if the wireless area constantly used by the subscriber is changed due to the relocation of the subscriber or the like, it is necessary to change the home memory station to a location closer to the wireless area to access the distant home memory station. Therefore, the utilization efficiency of the signal equipment can be increased accordingly.
