METHOD AND SYSTEM FOR GLOBAL POSITION REFERENCE MAP (GPRM) FOR AGPS
First Claim
1. A method of processing signals, the method comprising:
- transmitting reference location data from a GPS enabled device to a location server, wherein said location server determines a global position reference map (GPRM) based on said transmitted reference location data; and
receiving from said location server, said determined global position reference map by said GPS enabled device.

Abstract
Aspects of a method and system for global position reference map (GPRM) for AGPS are provided. A GPS enabled device may transmit reference location data to a location server and responded with a global position reference map (GPRM) from the location server. The reference location data and/or the received GPRM may comprise reference positions, which may be any identifiable location information, for the GPS enabled device. The reference location data may be formatted via various location identifiers such as a RNC ID, MCC and/or a MNC indicating desired coverage areas for the received GPRM. The reference location data may be a portion of a reference position database inside the GPS enabled device. The reference position database may be updated via the received GPRM. A fast position fix for the GPS enabled device may be achieved by combining AGPS data or LTO AGPS data, and the reference position database.
