<p>A two-way messaging system is created by overlaying a one-way inbound messaging system (50) onto a one way outbound messaging system (10) having a subscriber list. The two-way messaging system includes the one-way outbound messaging system and a two-way subscriber unit capable of transmitting an inbound message. The two-way subscriber unit includes a transmitter (206) that transmits the inbound message on an inbound channel without determining a busy/idle status of the inbound channel. A plurality of overlay base receivers (54) receive and decode the inbound message to provide an inbound decoded signal.</p> |
