In order to provide a configuration that allows system building with a relatively simple configuration when building a 3G mobile network system, a RAN part (11, 12, 13, 111, 112, 113, 114, 121, 122), a MSC (131), and a SGSN (132) are shared by a plurality of carriers, and subscriber information is consistently exchanged between a VLR of the shared MSC and HLRs of MSCs (211, 221, 231) for respective carriers, thereby maintaining the consistency with each other.
