ABSTRACT:
A switching station etc., are provided. When a mobile station moves from an area of a switching station into an area of another switching station having a VLR which has accepted the maximum number of subscribers, the switching station registers subscriber location information about the mobile station in an HLR even through it cannot register the subscriber service information in its VLR. When a call origination signal is transmitted from the mobile station, the switching station performs call origination connection processing by acquiring the subscriber service information about the mobile station from the HLR. When call termination to the mobile station occurs, the switching station can perform call termination processing normally since the subscriber location information is correctly updated in the HLR. The switching station performs call termination processing by acquiring the subscriber service information from the HLR.
