Abstract
Systems and methods for location tracking in a communication network. Base stations transmit downlink signals to a plurality of subscriber terminals to define a mapping between geographical locations and respective sets of signal strengths of the downlink signals received from the base stations at the geographical locations. A subset of the subscriber terminals may be selected, and for each subscriber terminal in the subset, first measurements of a geographical location of the subscriber terminal irrespective of the downlink signals is made. Second measurements of the downlink signals received at the subscriber terminal at the geographical location is made and the mapping of the subscribers terminals is updated responsively to the first and second measurements. The geographical locations of the subscriber terminals is updated using the updated mapping.
