Method and system for selecting optimal satellites for A-GPS location of handsets in wireless networks |
摘要 |
A system and method for determining a set of satellites for which assistance data may be provided to a wireless device. A boundary for an approximate area in which the wireless device is located may be determined and one or more sets of satellites may be determined as a function of the boundary. An optimum set of satellites from the one or more sets of satellites may then be determined using a satellite selection function on the one or more sets of satellites at predetermined points substantially on the boundary. |

1. A method for determining a set of satellites for which assistance data may be provided to a wireless device, comprising the steps of:
(a) determining a boundary for an approximate area in which the wireless device is located; (b) determining one or more sets of satellites as a function of said boundary; and (c) determining an optimum set of satellites by a communications network element from said one or more sets of satellites as a function of the visibility of each of said one or more sets of satellites at predetermined points substantially on said boundary. |
