METHOD AND SUBSCRIBER STATION FOR DERIVING SEED POSITION OF A SUBSCRIBER STATION IN SUPPORT OF UNASSISTED GPS-TYPE POSITION DETERMINATION IN A WIRELESS COMMUNICATION SYSTEM

摘要

Methods and systems are provided for determining a position of a subscriber station in a wireless communications system. The subscriber station receives an overhead message from the wireless communications system and obtains a parameter value. A data structure stored in memory of the subscriber station is then accessed and a seed position is set to a stored position from an entry of the data structure associated with a value matching the parameter value obtained from the received overhead message. The position of the subscriber station is then determined from a set of signals from a satellite position determination system based on the set seed position.
