ABSTRACT:
A telecommunications system and method is disclosed for determining the address of both the home and serving Mobile Positioning Centers (MPCs). Each Mobile Switching Center/Visitor Location Register (MSC/VLR) and Home Location Register (HLR) within a Public Land Mobile Network (PLMN) will be provided with the MPC address that is valid for its PLMN. When a Mobile Station (MS) roams into a new (serving) PLMN, a Location Update is performed by the serving MSC/VLR to the Home Location Register (HLR). The MPC address for the serving MSC/VLR will be included in every location update operation to the HLR, which can then store this serving MPC address in the subscriber's HLR record. Furthermore, the home MPC address, valid for the PLMN of the HLR, is included in every subscriber data transfer operation from the HLR to the serving MSC/VLR, which can then store this home MPC address, in the subscriber's VLR record.
