    Abstract: In a radio communication system a method of directing a communicating unit to utilise a communication resource includes the step of: informing a receiving communication unit, on a first channel or frequency, of at least one alternative channel or frequency (200) that is to be used for a communication if the first channel or frequency is used for a call. The at least one alternative frequency or channel (200) includes a single favourite frequency or channel (210) and a cyclically transmitted list of secondary frequencies or channels (212). This mechanism allows a base transceiver station (BTS) to indicate to a fleet of mobile stations (MSs) that are serviced by the BTS, a set of frequencies that will be used in the event that the current monitoring frequency ceases to remain available.

    Abstract: A self-organising wireless communication system (10) includes a plurality of wireless serving communication units (24-30) serving a plurality of mobile stations (12-16) with a limited communication resource (18-22). At least one wireless serving communication unit (24-30) includes a transmitter transmitting a wireless transmission message (190) including at least a yoohoo message portion (198). The yoohoo message portion (198) identifies whether transmissions from other wireless serving communication units can be received by the at least one wireless serving communication unit (24-30). This enables several BTSs or repeaters to share simultaneously a single frequency and to indicate to their respective fleets of MS's which frequency they are currently permitted to use and need to monitor for their transmissions. This is achieved partly through the concept of a 'map' of other transmissions to allow access and coordination. It also allows collisions to be detected and resolved when they are likely to occur.
