Abstract: A position location system, method, and apparatus are disclosed. A wireless device receives a first signal and obtains an identifier indicative of a first location from the first signal. The first signal can be received from a cellular base station and the first identifier can be a mobile country code. The wireless device uses the identifier to determine the availability of signals from a regional satellite system at the first location. If signals from the regional satellite system are available at the first location, the wireless device retrieves information associated with one or more satellite vehicles in the regional satellite system. The information can include pseudo-random number codes and a Doppler search range corresponding to the first location. The wireless device receives a second signal and processes the second signal to obtain first satellite signal information. The wireless device determines its position at least partially based on the first satellite signal information.

Abstract: The subject matter disclosed herein relates to a system and method for reducing an initial position uncertainty of a mobile station. In one example, although claimed subject matter is not so limited, a process to improve an initial position estimate comprises identifying the locations of a serving cell and at least one other landmark proximate to a receiver and determining an initial estimate of the location of the receiver based, at least in part, on the identified locations of the serving cell and the at least one other landmark.

Abstract: Information known to the mobile station, such as but not limited to location, date, time, user preferences, etc. is combined with information gained from an application in progress, such as but not limited to an Internet web page, e-mail message, photograph application, or information directly input by the user. The user is then presented an intelligent list of location-based options to access.
