System and method for informing network of terminal-based positioning method capabilities
First Claim
1. A telecommunications system for determining an optimum positioning method for locating a given one of a plurality of mobile terminals in within a cellular network, said telecommunications system comprising:
- a mobile switching center within said cellular network, said given mobile terminal being in wireless communication with said mobile switching center, said given mobile terminal having terminal-based positioning method information associated therewith, said given mobile terminal sending a message having said terminal-based positioning method information to said mobile switching center; and
a positioning node in communication with said mobile switching center, said positioning node having network-based positioning method information stored therein, said mobile switching center sending said terminal-based positioning method information to said positioning node, said positioning node determining said optimum positioning method based upon said network-based positioning method information and said terminal-based positioning method information, said positioning node using said optimum positioning method to locate said given mobile terminal.

Abstract
A telecommunications system and method is disclosed for allowing a cellular network to determine the optimum positioning method, having knowledge of all available network-based and terminal-based positioning methods. This can be accomplished by the Mobile Station (MS) sending to the Mobile Switching Center/Visitor Location Register (MSC/VLR) a list of terminal-based positioning methods that the MS is capable of performing. This list can, in turn, be forwarded to the Mobile Positioning Center (MPC) for determination of the optimum positioning method. For example, in a GSM network, the MS CLASSMARK information, which is sent to the MSC/VLR when the MS registers with the MSC/VLR, can be extended to include the MS'"'"'s positioning capabilities.
