Embodiment Construction

[0022] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any embodiment or design described herein as "exemplary" is not necessarily understood to be preferred or advantageous to other embodiments or designs. In addition, in the following description, "location" and "position" are synonymous terms used interchangeably.

[0023] figure 1 The cellular communication network 100 supporting the location determination of the wireless terminal is displayed. The wireless network 100 may be a CDMA network, a time division multiple access (TDMA) communication network, or some other wireless communication network. A CDMA network can implement one or more standards such as IS-95 and IS-2000; a wideband CDMA (W-CDMA) standard such as UMTS (Universal Mobile Telecommunications System); and so on. A TDMA network can implement one or more standards such as the Global System for Mobile Communications (GSM). These standards are well known in the fie...

Abstract

A method and apparatus for creating and using a base station almanac for position determination is described. The base station almanac includes a number of records, where each record can describe a sector or a transmitter (e.g., a base station or a repeater) in a wireless communication network. Each record includes a protocol type field that indicates the one or more protocols supported by the record (e.g., IS-801, J-STD-36, GSM, W-CDMA, and so on). Each record also includes a unique sector identifier for the sector / transmitter for each supported protocol, where each identifier is defined based on the associated protocol. A record may also include multiple maximum antenna ranges (MARs), where each MAR is associated with a respective reference power level. One of the multiple MARs can be selected for use for position determination depending on received signal strength. The base station almanac further includes other features.

Description

[0001] Related applications [0002] This application claims priority from U.S. Provisional Application No. 60 / 489,038 filed on July 21, 2003. Technical field [0003] The present invention generally relates to location determination, and more specifically, to a method and apparatus for creating and using a base station almanac (BSA) for location determination. Background technique [0004] It is often necessary (and sometimes necessary) to know the location of the wireless user. For example, the Federal Communications Commission (FCC) has adopted a report and instruction for the enhanced 911 (E-911) wireless service, the enhanced 911 (E-911) makes a 911 call from a wireless terminal every time At this time, the location of the wireless terminal (for example, a cellular phone) needs to be provided to a public safety answering point (PSAP). In addition to FCC requirements, service providers can use location services (ie, services that identify the location of wireless terminals) in...
