ABSTRACT:
A subscriber normally uses telephone sets 1 and 2 and a facsimile machine 3 accommodated in a wired telephone network 4, a subscriber terminal unit 10 that is a handy phone accommodated in a low speed mobile communication network 5, and a subscriber terminal unit 11 that is a portable telephone set accommodated in a high speed mobile communication network 6. Each of the networks is connected to a home database 7 to which the subscriber has subscribed. The home database 7 shares mobility management information for tracking a subscriber to which a call is connected in the wired communication system and mobility management information for registering the location of the subscriber who travels in the mobile communication system. The home database 7 updates the mobility management information for tracking the location of the subscriber with a location registration update request signal issued by the subscriber and changes the subscriber tracking priority.
