Mobile communication network system and location registration method

摘要

A mobile communication network system capable of reducing electric power consumption of each of a mobile station (MS) and a base station (BS) by performing cooperative communication linkage between a plurality of wireless systems (100, 200). The mobile communication network system comprises a storage unit (300) storing location information of the mobile station (MS), an acquisition unit (MSC) acquiring, when receiving a location registering request from the mobile station, a communication-enabled mobile communication system of the mobile station as a sender of the location registering request, a specifying unit (301) specifying a base station existing within the acquired mobile communication system and existing in the periphery of the base station receiving the location registering request, and a control unit (MSC) storing, into the storage unit, information of the base station receiving the location registering request and information of the specified base station as location information about the sender mobile station of the location registering request.
