METHODS AND SYSTEMS FOR DERIVING SEED POSITION OF A SUBSCRIBER STATION IN SUPPORT OF UNASSISTED GPS-TYPE POSITION DETERMINATION IN A WIRELESS COMMUNICATION SYSTEM |
摘要 |
<p>In a method and system for deriving a seed position of a subscriber station in a wireless communications system in supporting unassisted GPS-type position determination, the subscriber station receives overhead messages from the wireless communications system, and derives the seed position from the parameter values. The subscriber station may use a data structure in its memory and map possible parameter values to corresponding positions that may serve as the seed positions. The data structure may be updated in response to an update condition.</p> |
