Method and system for providing enhanced location based information for wireless handsets
First Claim
1. A method of providing an enhanced location based service via a mobile device, comprising:
- determining, via a processor of the mobile device, an initial location value that identifies the current location of the mobile device;
computing an initial location accuracy value for the determined initial location value;
establishing a communications group with a plurality of transceivers in response to determining that the computed initial location accuracy value exceeds a threshold value;
receiving, in response to establishing the communications group, location information from each of the plurality of transceivers in the communications group;
determining a trilateration position value based on the location information received from each of the plurality of transceivers in the communications group;
computing a trilateration variance value based on the determined trilateration position value;
determining a final location value based on the determined initial location value, the computed initial location accuracy value, the determined trilateration position value, and the computed trilateration variance value; and
using the final location value to provide the enhanced location based service.

Abstract
Methods, devices and systems for generating enhanced location information on or about a mobile device. A mobile device may be configured to determine an initial location value, compute an initial location accuracy value, compare the initial location accuracy value to a threshold value, and establish a communications group with a plurality of transceivers in response to determining that the initial location accuracy value exceeds the threshold value. In response to establishing the communications group, the mobile device may receive location information from the transceivers, use the received location information to determine a trilateration position value, and compute a trilateration variance value. The mobile device may then determine a final location value based on a combination of the initial location value, initial location accuracy value, trilateration position value, and trilateration variance value, and use the final location value to provide an enhanced location based service.
