POSITION REGISTERING METHOD, RADIO CONTROL STATION, AND EXCHANGE

摘要

In a position registering method, a radio control station (RNC) transmits report information including a first position number, which has been extracted by using a cell identifier as key information, to the cell identified by the cell identifier. A mobile station (UE) transmits a position registration request when the first position number included in the report information is different from a position number stored in the mobile station. The radio control station (RNC) notifies the first position number and the second position number, which have been extracted by using as the key information the cell identifier for identifying the requester of the position registration request, and a user identifier for identifying the mobile station. An exchange (MSC/SGSN) stores the notified user identifier, first position number, and second position number in association with one another.
