Handoffs in extended range concentric cell base station

摘要

The present invention is a method for performing handoffs in wireless communications systems having extended range concentric cell base station, wherein the concentric cell base station has a micro cell and a macro cell that incorporates multiple timing protocols to extend the base station's access range. In one embodiment, the base station determines whether a handoff is to be performed using absolute path delay information, which will indicate the current and previous positions of a mobile-telephone. If the absolute path delay information indicates that the mobile-telephone is moving between the macro cell and the micro cell, or to a cell associated with another base station, the current base station will instruct the mobile-telephone to perform a handoff to the frequency band associated with the micro cell, macro cell or base station to which the mobile-telephone is traveling towards.
