Abstract
A technique for improving location accuracy based on a priori geographical location density information is disclosed. In accordance with the illustrative embodiment, geographical location density information is derived from historical wireless location data such as the locations of prior E911 emergency calls, Location Based Services (LBS) sessions, conventional voice calls, packet data sessions, vehicle routes, and so forth. The geographical location density information is represented by a probability distribution function, and is incorporated into an existing location technique. Advantageously, the technique of the present invention can be employed in conjunction with any existing location technology; moreover, the historical location data can be obtained via any technology, and from any wireless network, including those that are different than that of the future location estimates.
