Abstract

An apparatus, method and system for matching subscriber states in network in which public land mobile network and wired/wireless private network are interworked are disclosed. The system matches subscriber state information of the public network to subscriber state information of the private network by allowing the private network to transmit state information of a mobile station toward the public network, the mobile station being located in a public and private cell area. The method includes the steps of a) allowing the private network to check state of a mobile station located in a public and private cell area and transmit the subscriber state information associated with the mobile station toward the public network; and b) allowing the public network to receive the subscriber state information and update the state of the mobile station in a visitor location register. The step a) is carried out when the state of the mobile station is changed or when an incoming signal from the public network is directed to the mobile station, which is in a local-area call connection state.

2. The method as set forth in claim 1, wherein the field includes a 4-byte message identification field.

3. The method as set forth in claim 1, wherein the field includes a 4-byte message sub-identification field.

4. The method as set forth in claim 1, wherein the message includes a location registration message and the field includes a 1-byte registration type field.

5. A method, comprising:

in a public and private mobile communication system interworked with a public land mobile network including one or more mobile switching centers, a plurality of public-network base station controllers coupled to each mobile switching center, and a plurality of public-network base station transceiver subsystems forming a public cell area and being coupled to each base station controller, the public and private mobile communication system including a public and private communication service apparatus coupled to one of the base station controllers, and at least one private base station transceiver subsystems forming a public and private cell area and being coupled to the public and private communication service apparatus, matching subscriber state information of a public land mobile network and subscriber state information of a wired/wireless private network in a public and private mobile communication system interworked with the public land mobile network, by;

a when a terminal located in the public and private cell area gives a response to a paging signal from the private network, allowing the public and private communication service apparatus to generate a message including a field in which state information of the terminal is recorded and transmitting the message to the public-network base station controller, the state information of the terminal indicating a busy state; and

the public-network base station controller receiving and reading the field indicating the state information of the terminal included in the message and update state information of the terminal located in a visitor location register on the public side.

6. The method as set forth in claim 5, further comprising the steps of:

when a call between the terminal and the private network is terminated, allowing the public and private communication service apparatus to generate a message including a field in which state information of the terminal is recorded and transmitting the message to the base station controller, the state information of the terminal indicating an idle state; and

allowing the base station controller to receive and read the field indicating the state information of the terminal included in the message and update state information of the terminal located in the visitor location register.

7. The method as set forth in claim 6, wherein the field includes a 4-byte message identification field.

8. The method as set forth in claim 6, wherein the field includes a 4-byte message sub-identification field.

9. The method as set forth in claim 6, wherein the message includes a location registration message and the field includes a 1-byte registration type field.

10. The method as set forth in claim 5, wherein the field includes a 4-byte message identification field.

11. The method as set forth in claim 5, wherein the field includes a 4-byte message sub-identification field.

12. The method as set forth in claim 5, wherein the message includes a location registration message and the field includes a 1-byte registration type field.
