ABSTRACT:
In a mobile communication system of this embodiment, when a terminal device starts communications using a system that does not register the terminal device, it transmits a temporary use registration request to an exchange apparatus after it confirms based on message information from the exchange apparatus that use registration is permitted. Upon reception of the temporary use registration request, the exchange apparatus authenticates the request source terminal device, and thereafter, supplies the terminal identification number of the own system to the terminal device. In addition, the exchange apparatus stores the supplied terminal identification number in correspondence with the home terminal identification number of the request source terminal device, so as to process incoming/outgoing traffic or calls associated with the terminal device on the basis of the stored information.
