Abstract
A hybrid multizone call delivery system delivers calls to portables by broadcasting from a central node a portable identification number (PIN) and dial-in number (DN) to all the zones in the system. Portables register their presence in zones as they roam throughout the coverage area. When a zone matches a broadcast PIN to a PIN registered therein, a zone controller pages the portable and initiates a call back to the broadcast DN. Upon receipt of the call back, the central node connects the incoming call to the portable through the call back connection.
