Abstract
An improved system and method for determining a position of a mobile station in a mobile telecommunications system is disclosed. The system includes identifying a number of location measuring units (LMUs) for measuring the time of arrival of signals generated by the mobile station. In the event one or more of the LMUs is associated with a mobile switching center (MSC) other than the MSC serving the mobile station, then information pertaining to the identified LMUs and the other MSC is sent to the serving MSC. The serving MSC sends a position request message to those identified LMUs associated therewith, encapsulates the position request message and sends the encapsulated message to the other MSC. The other MSC thereafter unpacks the position request message and forwards the unpacked position request message to the identified LMU associated with the other MSC. Following the measuring of timing information, the LMU associated with the other MSC sends its timing measurement results to the other MSC, which thereupon encapsulates the results and forwards the encapsulated results to the serving MSC.
