Abstract
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 information obtained via a geospatial system of the mobile device is accurate, collects location information from a plurality of mobile devices in response to determining that the information obtained via the geospatial system of the mobile device is not accurate, 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 uses the computed more precise location 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.
