Method and System for Providing Enhanced Location Based Information for Wireless Handsets

Methods, devices and systems for generating enhanced location information on or about a mobile device may include hybrid lateration and/or trilateration solutions in which the mobile device determines whether the mobile device is able to acquire satellite signals and navigation data from a geospatial system, collects location information from a plurality of mobile devices in a communication group in response to determining that the mobile device is not able to acquire satellite signals and navigation data from the geospatial system, computes computing more precise location information (including three-dimensional location and position information) based on the location information collected from the plurality of mobile devices, and using the generated location and position information to provide an enhanced location based service, such as an emergency location service, a commercial location service, an internal location service and/or a lawful intercept location service.
