ABSTRACT:
A system controller (102) schedules an outbound selective call address (410) and an outbound message (430) at a position within a transmission cycle (330) of a synchronous outbound signaling protocol. The position and the outbound selective call address (410) are stored and linked to each other. The transmission cycle (330) is transmitted. A selective call transceiver (106) receives the transmission cycle (330), recovers the outbound message (430), and generates a response signal which includes an inbound address. The inbound address is determined from the position of the outbound selective call address (410) within the transmission cycle and is included in an inbound message which is transmitted. The system controller (102) recovers the inbound message, determines the position from the inbound address, and identifies the inbound message as being associated with the selective call transceiver (106) by the linking of the position to the outbound selective call address (410) stored within the system controller (102).
