Abstract
A communication system is described which provides call queueing between a base station (400) which does not have a control channel and a plurality of portable communication handsets (401). The base station (400) determines when all channels are busy, and following one becoming available, transmits a first predetermined code. All portable communication handsets (401) which attempted to communicate with the base station (400) when all channels were busy, sets a queue mode flag, and starts a timer (455, 461). When a first predetermined code is detected by any handset (401) having attempted to establish communication with the base station (400), the first timer (455, 461) continues, and a second timer (455, 461) operating at a second rate is started at the value established by the first timer (455, 461). When the second timer (455, 461) value reaches a predetermined value, the handset (401) proceeds to attempt to establish communication with the base station (400) on the channel that became available.
