System and method for routing positioning requests based on mobile switching center address
First Claim
1. A telecommunications system for routing a positioning request to determine the location of a given one of a plurality of mobile terminals in wireless communications with a mobile switching center, said telecommunications system comprising:
- a gateway mobile positioning center for receiving said positioning request and an identification number associated with said given mobile terminal from a requesting node in communication with said gateway mobile positioning center, said gateway mobile positioning center verifying the authorization of said requesting node to send said positioning request, said gateway mobile positioning center sending a rejection message to said requesting node when said requesting node does not have authorization to send said positioning request, the location of said given mobile terminal not being determined when said rejection message is sent;
a home location register connected to said mobile switching center, said home location register being identified using said identification number, said gateway mobile positioning center sending a routing request to said home location register, said home location register sending routing information associated with said mobile switching center to said gateway mobile positioning center; and
a positioning node in communication with said mobile switching center, said gateway mobile positioning center forwarding said positioning request to said positioning node, using said routing information, said positioning node determining the location of said given mobile terminal.

Abstract
A telecommunications system and method is disclosed for allowing a Gateway Mobile Positioning Center (GMPC) to route positioning requests to the Public Land Mobile Network (PLMN) where the subscriber is currently located without the need for storing the subscriber'"'"'s serving Mobile Positioning Center (MPC) address in the Home Location Register (HLR). When an external Requesting Application (RA) wants to locate a particular Mobile Station (MS), the RA contacts the GMPC, and provides the directory number of the subscriber that needs to be located. The GMPC then sends a request for routing information, e.g., the address of the serving Mobile Switching Center (MSC), to the subscriber'"'"'s HLR. The HLR then returns the routing information to the GMPC, which can then send the positioning request to the serving MSC, using the MSC address. The serving MSC can then route the positioning request to the serving Mobile Positioning Center.
