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.
4. The method of claim 1, wherein determining the mobile station position comprises:
determining a reference sector identification for the mobile station;
determining a coarse position fix of the mobile station; and
determining a final position estimate for the mobile station based in part on the coarse position estimate.
8. The method of claim 4, wherein determining the final position estimate comprises:
determining acquisition assistance data based on the coarse position fix;
transmitting the acquisition assistance data to the mobile station; and
determining a Global Positioning System (GPS) position fix for the mobile station.
10. The method of claim 4, wherein determining the final position estimate comprises a position determined according to at least one of the group comprising
Advanced Forward Link Trilateration (AFLT);
Hybrid GPS/AFLT;
a position determined based on knowledge of a sector orientation and an approximate range based on an RTD measurement;
a mixed cell sector fix determined based on knowledge of sectors in communication with the mobile station, and each sectors' position and orientation;
a current serving sector coverage area centroid position determination;
a centroid position of a current Network ID and System ID coverage region; and
a default position stored in a Position Determining Entity configuration file.
13. The method of claim 1, wherein selectively updating the positioning parameters comprises:
determining a first distance from the mobile station position to a base station antenna based on the mobile station position determined using Global Positioning System;
determining a second distance from the mobile station position to the base station antenna based on a pilot phase measurement; and
determining an updated forward link calibration (FLC) value based on a stored FLC value from the base station almanac, the first distance, and the second distance.
14. The method of claim 1, wherein selectively updating the positioning parameters comprises:
determining an estimate of a positioning parameter based on the mobile station position;
retrieving a stored positioning parameter from the base station almanac; and
computing an updated positioning parameter based on a weighted average of the estimate of the positioning parameter and the stored positioning parameter.
16. A positioning system in a wireless communication network, the system comprising:
a base station almanac configured to store positioning parameters for at least one base station;
a position determining entity (PDE) configured to determine a position of a mobile station in communication with a base station in the wireless communication system based in part on the positioning parameters; and
a base station almanac database server configured to selectively update the positioning parameters in the base station almanac based in part on the position of the mobile station.
19. The system of claim 16, wherein the PDE is configured to determine the position of the mobile station according to at least one of the group comprising:
Advanced Forward Link Trilateration (AFLT): and
Hybrid GPS/AFLT.
23. A positioning system in a wireless communication network, the system comprising:
means for storing, in the base station almanac, positioning parameters for base stations of the wireless communication network;
means for determining a mobile station position based in part on the positioning parameters;
means for determining a quality of the mobile station position; and
means for selectively updating the positioning parameters based in part on the quality and the mobile station position.
24. The positioning system of claim 23, wherein the means for determining the mobile station position comprises:
means for determining a reference sector identification for the mobile station;
means for determining a coarse position fix of the mobile station; and
means for determining a final position estimate for the mobile station based in part on the coarse position estimate.
25. The positioning system of claim 24, wherein
means for determining acquisition assistance data based on the coarse position fix;
means for transmitting the acquisition assistance data to the mobile station;
means for determining a Global Positioning System (GPS) position fix for the mobile station; and
means for determining an Advanced Forward Link Trilateration (AFLT) position fix based on the GPS position fix, and wherein the final position fix is based on the AFLT position fix and the GPS position fix.
