Abstract
A mobile communication network is provided with a plurality of base stations each of which communicates with a plurality of mobile stations, a plurality of base station controllers (BSC) or control stations each of which is connected to a group of base stations, and switching centers each of which is connected to a plurality of BSC's. The BSC's are interconnected by an exclusive network and terminal information of the mobile stations are stored by the respective local service points (SCP) of the BSC's in a decentralized manner. When an authentication processing and the retrieval of location data for a mobile station is to be made by each BSC and in the case where necessary terminal information is not held in the local SCP of that BSC, the BSC broadcasts a request message for transfer of terminal information or vicarious execution of authentication processing to other BSC's through the exclusive network and waits for a response message from a BSC in which the necessary terminal information is held.
