Abstract
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.
