A communication system (10) comprises a portable radio (20) and a plurality of mobile repeaters (12), a mobile repeater system 200 comprising a portable signal receiver (224) for receiving portable radio signals; a mobile transmitter (218) for transmitting the portable radio signals received by the portable receiver; a mobile receiver (226) for monitoring mobile transmissions; a delay state counter (202) for delaying the transmission of the portable radio signals received; and a received signal strength indicator (204) for determining the strength of received mobile radio signals, the received signal strength indicator being coupled to the delay state counter, via a controller (206), for decrementing the delay state counter when the mobile receiver does not detect a mobile transmission having at least a predetermined received signal strength level.

DETAILED DESCRIPTION Briefly, according to the invention, in a communication system comprising a portable radio and a plurality of mobile repeaters, a mobile repeater system comprises: receiver means for receiving portable radio signals; transmitter means for transmitting the portable radio signals received by the receiver means; monitor means for monitoring mobile transmissions; a delay state counter for delaying the transmission of the portable radio signals received; and a received signal strength indicator for determining the strength of received mobile radio signals, the received signal strength indicator being coupled to the delay state counter for decrementing the delay state counter when the monitor means does not detect a mobile transmission having at least a predetermined received signal strength level.
