ABSTRACT:
Methods and apparatus are provided for establishing a connection between a scanner device and a pager device over a sequence of hop channels. The scanner device is repetitively activated and a hop channel is selected from the sequence of hop channels as a function of a present phase. A determination is made as to whether the selected hop channel is a forbidden hop channel. A substitute hop channel is selected from the sequence of hop channels as the selected hop channel if the selected hop channel is a forbidden hop channel. The selected hop channel is monitored for receipt of a paging message during the present phase.
