Method and system for enhanced location based information for fixed platforms
First Claim
1. A method of providing a location based service on a first fixed wireless device, the method comprising:
- determining whether the first fixed wireless device is able to establish a location fix based on information obtained via a geospatial system;
collecting location information from a plurality of mobile devices in a communication group in response to determining the first fixed wireless device is unable to establish a location fix, wherein the plurality of mobile devices comprises at least a second wireless device;
computing more precise location information including a new three-dimensional location fix for the first fixed wireless device based on the location information collected from the plurality of mobile devices in the communication group, wherein computing the more precise location information comprises using horizontal data to determine a position relative to the Earth'"'"'s surface, using vertical data to determine a height of the position relative to sea level, and generating three-dimensional information based on the determined position and the determined height; and
using the generated three-dimensional information to provide a location based service.

Abstract
Fixed infrastructure devices (FIDs) may be configured to work with other devices (e.g., other FIDs, mobile wireless devices, etc.) to obtain or improve location information and/or provide enhanced location based services (e.g., emergency location service, commercial location service, internal location service, lawful intercept location service, etc.) to other devices or programs. For example, a first fixed wireless device may be configured to receive information that was obtained via a geospatial system, and determine whether it is able to establish a location fix based on this information. In response to determining that it is unable to establish a location fix based on the received information, the device may establish a communication group and/or collect additional location information from devices that belong to the communication group. The device may use this information to compute a new three-dimensional location fix, and use this new fix to provide the location based service.
