<p>A relay communications network is configured from a plurality of transceiver stations (12, 14, 16, 18, 20, 22 and 24) in a given area to transmit a message at a minimum transmission power by causing the station (12) which is to originate the transmission to interrogate those stations (18, 20 and 22) with which it can communicate directly as to their ability to communicate either directly or indirectly with a target station (14 and 16), causing each relay station (18, 20, 22, and 24) which can communicate with the target station to transmit to the originating station information as to a path by which relay station can communicate with the target station with a minimum transmission power and causing the originating station to select a serial call path through one or more of the relay stations.</p> |
