Culled satellite ephemeris information for quick, accurate assisted locating satellite location determination for cell site antennas

A method of culling a plurality of locating satellites into a sub-plurality for communication, comprising:

• defining a geometric shape above a reference point physically distant from a relevant mobile device;
• defining a first group of satellites having a higher priority for determining a location of said relevant mobile device;
• defining a second group of satellites having a lower priority for determining a location of said relevant mobile device relative to said higher priority;
• and
• culling said plurality of locating satellites to a culled group of locating satellites comprising said first group of satellites and said second group of satellites within said geometric shape defined above said reference point, said culled group being determined based on a dwell time within said geometric shape.

Apparatus for culling a plurality of locating satellites into a sub-plurality for communication, comprising:

• means for defining a geometric shape above a reference point physically distant from a relevant mobile device;
• means for defining a first group of satellites having a higher priority for determining a location of said relevant mobile device;
• means for defining a second group of satellites having a lower priority for determining a location of said relevant mobile device relative to said higher priority;
• and
• means for culling said plurality of locating satellites to a culled group of locating satellites comprising said first group of satellites and said second group of satellites within said geometric shape defined above said reference point, said culled group being determined based on a dwell time within said geometric shape.

A method of culling a plurality of locating satellites into a sub-plurality for communication, comprising:

• defining a geometric shape having an apex above a reference point physically distant from a relevant mobile device;
• culling said plurality of locating satellites to a culled group of locating satellites within said geometric shape defined above said reference point, said culled group being determined based on a dwell time within said geometric shape;
• and
• passing an identity of said culled group of locating satellites to said relevant mobile device.
