Abstract
A communication system (10) having a plurality of selective call transceivers (30) which can operate as one-way selective call receivers in a one-way coverage zone (16) or as selective call transceivers in a two-way coverage zone (36) comprises a plurality of outbound transmitters (17, 18, and 19) covering one-way coverage zones (12, 14, and 16 respectively) and a plurality of base receivers (37, 38, and 39) and transmitters (11, 13, and 15) covering two-way coverage zones (32, 34, and 36 respectively), a plurality of selective call transceivers (30) having a preferred one-way zone list and controllers (41-46) having a preferred one-way zone list matching the preferred one-way zone list in the selective call transceiver, the selective call transceivers capable of detecting the one-way coverage zone and disabling the two-way function of the selective call transceiver.
