Abstract

An identification-information extracting unit extracts first identification information of a location registration area of a wireless communication system. A storage unit stores correspondence information concerning a relationship between the first identification information and second identification information of a location registration area managed by a communication network system. A location-registration requesting unit transmits location-registration request information for requesting a location registering device to perform a new location registration when the second identification information is updated by a movement of a mobile terminal.

Claims

1. A location registration method employed in a mobile terminal communicating with a base station, the location registration method comprising:

a first reception step of receiving a location registration identifier specific to an area corresponding to the base station from the base station;

a determination step of determining whether the received location registration identifier is present in a first identification information list, which stores therein the location registration identifiers in advance;

a first transmission step of transmitting a location-registration request message to a controller by way of the base station, when determining that the received location registration identifier is not present in the first identification information list at the determination step;

a second reception step of receiving a second identification information list from the controller as a location-registration response message; and

an update step of storing the received second identification information list.

2. The location registration method according to claim 1, wherein

the second identification information list is updated by the controller based on the location-registration request message.

3. The location registration method according to claim 1 or 2, wherein

the second identification information list is added to the location-registration response message and transmitted to the mobile terminal.

4. The location registration method according to any one of claims 1 to 3, wherein

the first identification information list is deleted when the second identification information list is stored.

5. The location registration method according to any one of claims 1 to 4, wherein

the controller is a paging agent.
