Wireless transmit station search window reduction

摘要

Techniques disclosed herein are directed toward make use of known wireless transmit station geometry (e.g., from a cell location database/almanac) to create an optimized search window, where the size of the search window is a function of an angle between a line from the center of the region of position uncertainty of the mobile device to the location of the reference transmit station, and a line from the center of the region of position uncertainty of the mobile device to the location of the remote transmit station. Techniques can be utilized for various types of wireless transmit stations not only in cell networks, but Global Navigation Satellite Systems as well.

主权项

1. A server for providing a search window for a remote antenna, used in mobile device positioning, the server comprising:
a communication interface; a memory; and a processing unit communicatively coupled with the communication interface and the memory, the processing unit configured to cause the server to: receive, via the communication interface, information indicative of an identity of a reference antenna for a mobile device; in response to receiving the information indicative of the identity of the reference antenna, obtain reference antenna information and remote antenna information; determine a size of the search window for the remote antenna, wherein the size of the search window for the remote antenna is a function of the reference antenna information and the remote antenna information; and send, via the communication interface to the mobile device, information indicative of the determined size of the search window for the remote antenna.
