Method and apparatus to select an optimum site and/or sector to provide geo-location data

A method of geo-locating a mobile station in a geographic area serviced by a plurality of base station sites co-located with location measurement units (LMUs), the method comprising:

• selecting a reference position within a communication coverage area of a of a first site;
• selecting at least one secondary site according to a function of the reference position;
• selecting at least one secondary sector of the at least one selected secondary site to task based on a function of the reference position;
• and
• tasking the at least one secondary sector to obtain location information of the mobile station,
• wherein the step of selecting at least one secondary site further comprises administering a proximity test to flag the site that is closest to the reference position so that site will not be considered an available candidate site.

• selecting at least one sector of the at least one selected secondary site to task based on the reference position;
• and
• tasking the at least one sector to obtain location information of the mobile station,
• wherein the step of selecting at least one secondary site further comprises calculating a cost function to determine which secondary site has a minimum total cost and flagging that site as no longer considered an available candidate site.

A method of geo-locating a mobile station in a geographic area serviced by a plurality of base station sites co-located with location measurement units (LMUs), the method comprising:

• determining the locations of secondary base station sites with respect to a serving base station site location;
• selecting a mobile station reference position based on the type of location arrangement of the secondary sites;
• selecting at least one secondary site according to a function of the reference position by administering a proximity test to flag the site that is closest to the reference position so that site will not be considered an available candidate site;
• selecting at least one secondary sector of the at least one selected secondary site to task based on a function of the reference position;
• and
• tasking the at least one secondary sector to obtain location information of the mobile station.
