Creating And Using Base Station Almanac Information In A Wireless Communication System Having A Position Location Capability
First Claim
1. A method of maintaining a base station almanac in a wireless communication network, the method comprising:
- storing, in the base station almanac, positioning parameters for base stations of the wireless communication network;
determining a mobile station position based in part on the positioning parameters;
determining a quality of the mobile station position; and
selectively updating the positioning parameters based in part on the quality and the mobile station position.

Abstract
In a wireless mobile communication system having a position determination service, base station information is stored in a base station almanac. In addition to the position of the base station antenna, forward link delay calibration, and base station identification information, a base station almanac record includes the center location of the base station sector coverage area, the maximum range of the base station antenna, the terrain average height over the sector coverage area, the terrain height standard deviation over the sector coverage area, round-trip delay (RTD) calibration information, repeater information, pseudo-random noise (PN) increments, uncertainty in the base station antenna position, uncertainty in the forward-link delay calibration, and uncertainty in the round-trip delay calibration.
