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.
Claims17
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.

An apparatus comprising:
- first implementing means for 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 means for selecting a single one of the location estimates based on predetermined criteria for providing a particular location estimate for the mobile station in a cellular communications network;
- and
- first determining means for determining respective distances between each of said sites with which the mobile station has a radio link and the location estimates, wherein the predetermined criteria use said respective distances to determine which single one of said location estimates is selected.
1 more element
An apparatus, comprising:
- a first processor configured to implement 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;
- a controller configured to select a single one of the location estimates based on predetermined criteria to provide a particular location estimate for the mobile station in a cellular communications network;
- and
- a first determining unit configured to determine respective distances between each of said sites and the location estimates, wherein the predetermined criteria use said respective distances to determine which single one of said location estimates is selected.
