Abstract:
Methods and apparatuses are provided which may be used in mobile stations to perform or otherwise support location services. Signals representing existing SPS-related information associated with the mobile station can be stored during a MS-based or a standalone GNSS tracking session. In response to a request for an MS-assisted location session, the existing SPS-related information can be compared to a threshold. Signals representing the requested SPS-related information can be generated based on the existing SPS-related information and stored in memory.
