Embodiment Construction

[0032] The following description and drawings illustrate the invention and should not be considered as limiting the invention. Numerous specific details are described in order to provide a thorough understanding of the invention. However, in certain instances, well known or conventional details are not described in order to avoid obscuring the description of the present invention. References in this disclosure to one or an embodiment are not necessarily references to the same embodiment; and such references mean at least one.

[0033] Recent developments in wireless communication technology have resulted in the deployment of a variety of different wireless networks with substantially overlapping coverage in some areas. In this application, a wireless network refers to a group of wireless access points (e.g., base stations) with the same air interface, operated by a service provider (e.g., Verizon Wireless or Sprint), such that when a mobile unit is within the coverage of said...

Abstract

Methods and apparatuses for position determination and other operations. In one embodiment of the present invention, a mobile station uses wireless signals from a plurality of wireless networks (e.g., with different air interfaces and / or operated by different service providers) for position determination (e.g., for data communication, for obtaining time and / or frequency information, for range measurement, for sector or altitude estimation). In one embodiment of the present invention, mobile stations are used to harvest statistical data about wireless access points (e.g., the locations of mobile stations that have received signals from the wireless access points, such as from cellular base stations, wireless local area network access points, repeaters for positioning signals, or other wireless communication transmitters) and to derive location information (e.g., position and coverage area of the wireless access points) for the wireless networks from the collected statistical data.

Description

[0001] Information about divisional applications [0002] This application is a divisional application of the original Chinese invention patent application titled "Method and Device for Wireless Network Hybrid Positioning". The application number of the original application is 200480022868.6; the application date of the original application is June 28, 2004; the priority date of the original invention patent application is June 27, 2003. technical field [0003] The present invention relates to position determination systems, and more particularly, to hybrid positioning using wireless communication signals. Background technique [0004] To perform position location in a wireless cellular network, such as a cellular telephone network, several methods are based on performing trilateration using timing information sent between each of several base stations and a mobile device, such as a cellular telephone. A method measures at the mobile the relative time of arrival of signal...
