Abstract: The invention is directed towards a method for estimating a PRN synchronization and Doppler shift of a satellite signal at a reference location within a cell and sector of where a wireless terminal or WAG client is located. The estimates are based on information conveyed by a GPS signal acquired by an auxiliary system or WAG server, which may be at a location different from the wireless terminal or WAG client. The PRN synchronization and Doppler shift estimates are also based on some reference time, which is a time that is sufficiently far into the future to allow the WAG client to demodulate and decode the PRN synchronization and Doppler shift estimates from an assisting message transmitted by the WAG server and to use such estimates to acquire GPS signals, wherein the assisting message indicates the PRN synchronization and Doppler shift estimates.

Abstract: A wireless terminal (501) and auxiliary system (505) are disclosed that enable the wireless terminal to determine its location based on signals transmitted from navigation satellites (503). In particular, the tasks of signal acquisition and signal processing required of a wireless terminal in the prior art are divided between the wireless terminal (501) and the auxiliary system (505) in accordance with the illustrative embodiment. The auxiliary system assists the wireless terminal by acquiring information about the satellites' ephemerides, by partially processing it and by transmitting the partially processed information (via 504) to the wireless terminal in a form that is useful to the wireless terminal. The wireless terminal then uses the partially processed information from the auxiliary system to assist the wireless terminal in acquiring the ranging signals from the navigation satellites quickly and when they are weak.

Abstract: A wireless telecommunications system uses location or position information to initiate actions on behalf of travelers. As position information of a wirele ss mobile unit is received, it is compared to stored position information of a remote location , such as a home. As the traveler approaches his home, and gets within a certain distanc e of home, a signal is then sent to a controller within his home to perform an action o r instruct the performance of an action.

Abstract: METHOD AND APPARATUS FOR A WIRELESS TELECOMMUNICATIONS SYSTEM THAT PROVIDES LOCATION-BASED INFORMATION DELIVERY TO A WIRELESS MOBILE UNIT A wireless telecommunications system uses location or position information o f a wireless mobile unit to initiate the sending of location-specific informatio n to travelers. As position information is received, it is compared to prestored position information of a remote location, such as an airport. As the traveler approaches the remote location, and gets within a certain distance the remote location, information such as airline arrival information is retrieved and sent to the wireless mobile unit of the travele r. Thus, useful information tied to the position of the wireless mobile unit, such as airlin e or traffic information for example, is obtained.
