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.

26. A mobile terminal that communicates with a plurality of heterogeneous wireless communication systems, and that moves while performing a location registration within a communication network system having the wireless communication systems, the mobile terminal comprising:
-
an identification-information extracting unit that extracts first identification information specific to a location registration area of each of the wireless communication systems from information received from each of the wireless communication systems; a first storage unit that stores therein correspondence information concerning a correspondence relationship between the first identification information and second identification information of a location registration area managed by the communication network system; and a location-registration requesting unit that extracts the second identification information corresponding to the first identification information based on the first identification information extracted by the identification-information extracting unit and the correspondence information stored in the first storage unit, and transmits location-registration request information for requesting the location registering device to perform a new location registration when the second identification information is updated by a movement of the mobile terminal.
