Abstract

The mobile communication network system having a plurality of mobile communication systems each including a base station performing wireless communications with a mobile station, comprises a storage unit storing location information of the mobile station, an acquisition unit acquiring, when receiving a location registering request from the mobile station, a communication-enabled mobile communication system in the mobile station as a sender of the location registering request, a specifying unit specifying a base station existing within the acquired communication-enabled mobile communication system and existing in the periphery of the base station receiving the location registering request, and a control unit storing the storage unit with 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.

Claims2

Dependent claims

A mobile station device capable of communicating with a plurality of mobile communication systems within a mobile communication network system, each of the plurality of mobile communication systems corresponding to a different communication method, the mobile station device comprising:

a plurality of wireless interfaces each implementing any one of the different communication methods;
a power control unit controlling the plurality of wireless interfaces such that any one of the plurality of wireless interfaces becomes communication-enabled, wherein the communication-enabled wireless interface is set as a waiting wireless interface;
a comparing unit comparing, based on an incoming notification received by the waiting wireless interface, a requested mobile communication system designated by information included in the incoming notification with a mobile communication system corresponding to the communication method implemented by the waiting wireless interface;
a switchover unit directing the power control unit to switchover the wireless interface implementing the communication method of the requested mobile communication system to be communication-enabled, when the comparing unit judges that the requested mobile communication system is different from the mobile communication system implemented by the waiting wireless interface;
and
a transmitting unit transmitting a location registering request, for informing the mobile communication system corresponding to the communication method implemented by the waiting wireless interface, through the post-switchover wireless interface.
