This non-provisional application for patent is a divisional of patent application Ser. No. 11/205,510 filed Aug. 16, 2005, now U.S. Pat. No. 7,925,210, issued on Apr. 12, 2011, which is a continuation-in-part of patent application Ser. No. 10/154,138, filed May 21, 2002, now U.S. Pat. No. 7,877,104, issued on Jan. 25, 2011, and which further claims the benefit of U.S. Provisional Patent Application No. 60/292,774 filed on May 21, 2001, and the disclosure of each is herein incorporated by reference in its entirety.
In FIG. 1 a typical GPS architecture is shown. System 100 comprises GPS satellite 102, which is illustrative of the constellation of GPS satellites that are in orbit, a MS (i.e. wireless handset 104) which may include a GPS receiver, a base station 106, a geolocation (server) service center 108, a geolocation end application 110, and a Public Safety Answering Point (PSAP) 112. The Mobile Station (MS) 104, such as a wireless handset, Personal Digital Assistant (PDA), or similar mobile device may have location technology of the present invention and may use GPS technology in support of various MS device implementations of E911 and geolocation services. The PSAP 112 and the geolocation end application 110 are included for reference only.

In FIG. 5, a flow diagram 500 of offset determination is shown. A wireless handset 104 receives a GPS signal 114 at a GPS receiver in step 502. The wireless handset 104 also receives a communication signal 116 from the wireless network in step 504 that contains timing information. The controller then determines the time offset and/or drift between the clock at base station 106 sent in the received communication signal 116 and the GPS time sent in GPS signal 114 in step 506. The offset may then be sent back to the current base station 508.
