A base station (14) in an idle channel marked mobile radiotelephone system is provided with means (26, 27) for inhibiting station removal of idle marking tone from a channel for a time interval .tau..sub.RD of randomly selectable duration following initiation of the tone on the channel. That inhibit interval forces mobile units using so-called instant channel grabbers at idle tone initiation time to operate through at least two full executions of the normal access-requesting tone program, thereby providing an opportunity for a mobile unit using a random-delay seizure algorithm to access the channel between or during the executions of the instant channel grabber mobile unit.
A method for forcing randomization of access to a shared communication channel on which a signal is transmitted to indicate availability of the channel for message transmission, the channel extending between a first station supplying such tone and at least one further station, and the method comprising the steps of
In a communication system including at least one user-shared-access communication channel and a first station for controlling the access of multiple, remotely located users to that channel by applying to said channel a signal indicating the availability thereof for access by a user, and wherein user station equipment seeking access initiates a predetermined program of access-requesting signals, and, if thereafter the availability signal is still present on the channel, said equipment reinitiates said program at least once, said first station comprising
