1. A method comprising:
- implementing in parallel a plurality of different location estimate generation methods, each different method generating a location estimate, each of said plurality of different location estimate generation methods using at least one estimate of distance between a mobile station and at least one of a set of sites;
selecting one of the location estimates based on predetermined criteria to provide a particular location estimate for the mobile station in a wireless communications network, wherein the mobile station has a radio link with the set of sites; and
determining respective distances between each site in the set of sites and the location estimates, wherein the predetermined criteria use said respective distances to determine which single one of said location estimates is selected.

Abstract
A method of providing a location estimate for a mobile station in a wireless communications network. The method of providing the location estimate includes implementing, in parallel, a plurality of different location estimate generation methods, each location generation method generating a location estimate. The method of providing the location estimate also includes selecting one of the location estimates based on predetermined criteria.
