Abstract
Multiple location finding equipment (LFE) inputs are used to enhance location information made available to wireless location-based applications. A wireless network utilizes a mobile switching center to route communications between wireless stations, a network platform, and a variety of LFE systems. A Location Finding System (LFS), resident on the network platform, receives location information from the LFEs and provides location information to wireless location based applications. In this regard, the LFS can receive input information at varying time intervals of varying accuracies and in various formats, and can provide standardized outputs to the applications, for example, depending on the needs of the applications. Multiple inputs may also be co-processed for enhanced accuracy. A specification can be used to ensure that location information at least meets certain minimum criteria, such as geographical accuracy, allowable age, acceptable response time, and confidence.
