1. A method, comprising:
- determining additional fix information associated with an estimation of a position of a mobile station, wherein said additional fix information comprises one or more measurements obtained from processing one or more wireless signals received at a receiver of the mobile station from one or more base stations;
storing the additional fix information in a memory of the mobile station in a current fix database entry in a fix database based, in part on,determining a priority value for the current fix database entry,comparing the priority value for the current fix database entry with priority values for a plurality of previously stored fix database entries, andstoring the current fix database entry according to a priority scheme for the additional fix information; and
transmitting one or more signals representative of at least a subset of the additional fix information into a network.
