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.
