MIXED MOBILE COMMUNICATION SYSTEM OF WCDMA NETWORK AND CDMA NETWORK HAVING NDSS FUNCTION, AND METHOD FOR LOCATION REGISTRATION OF MOBILE COMMUNICATION TERMINAL IN THE SAME

摘要

It proposes an asynchronous mobile communication system and the synchronous mobile communication system coexist with NDSS features a mobile communication system and a mobile communication terminal location registration method comprising a.; The invention in the asynchronous and synchronous mobile communication systems coexist a mobile communication system, the dual-band dual-mode to register the location of the mobile terminal, the home location register receives the preferred mobile communication system information of the mobile communication terminal subscriber store / manage and; Node B and the base station stores the overlap or failure information with other mobile communication systems in the area they are located / management and, when receiving a location registration request from the mobile communication terminal location registration request message including the overlapping information indicating whether the node B and the base station respectively and sent to; Asynchronous and synchronous switch selects the mobile communication system to be performed the location registration to receive the subscriber information including the preferred mobile communication system information from the asynchronous and synchronous home location register based on the location registration request of the mobile communication terminal.; According to the invention it is possible to improve the service quality by deriving the location registration to the synchronous mobile communication system and an asynchronous mobile communication system is in the overlapping area the mobile which has been the subscriber is registered as a preferred mobile communication system by the NDSS function communication system.
