ABSTRACT:
A fixed wireless access system includes circuitry for routing a call for a subscriber having a directory number not only through the primary cell, but also through any secondary cell for a border cell subscriber. In each case, the primary and secondary cells borders a geographically located near the geographic location of the border cell subscriber. For calls that are being routed to the border cell subscriber, one of a plurality of subscriber features including call forward no-answer, call forward unconditional or multiple access directory numbers may be used to cause the switch to trigger one or more fixed wireless access controllers to generate page request signals to the base stations for the border cell subscriber. For calls originated by the border cell subscriber, the subscriber's directory number is placed within the subscriber list for each base station whose cell borders are located geographically near the border cell subscribers geographic location. Accordingly, if the border cell subscriber unit locks onto a base station of a secondary border cell, the controller recognizes the subscriber unit and may process the call.
