Abstract
A decrease is realized in network load caused by a change in selection of location registration device or an increase or decrease in the number of installations, on a circuit switching network side. A mobile communication system includes a mobile station, a packet switching station, and a plurality of location registration devices that perform location management of the mobile station. With respect to the mobile station, after one location registration device is already selected from among the plurality of location registration devices, when the mobile station performs location registration, an NRI (Network Resource Identifier) included in a TMSI (Temporary Mobile Station Identifier) is transmitted to the packet switching station. The packet switching station makes a request for location registration with respect to the one location registration device, based on the NRI.
