  • Method of registering position of mobile communication terminal, general calling method for mobile communication terminal and mobile communication system
    Patent number: 7113784
    Abstract: A relay device installed in a moving unit can, by notifying an own identification number to a mobile communication network along with identification numbers of all mobile communication terminals subordinate to itself, perform en bloc updating of location registration area information of these mobile communication terminals. This relay device can receive an en bloc paging request wherein paging requests to plural subordinate mobile communication terminals are aggregated, reconstruct the received en bloc paging request, and transmit the paging requests to each of the mobile communication terminals subordinate to itself.
