Abstract
In a messaging system, message traffic is transmitted on one or more traffic channels T , T and the allocation of groups S , S of receivers to the traffic channels T , T is controlled by information transmitted on a bulletin board channel BB. A predetermined number of frames before a change in the traffic channel allocation, a countdown value is transmitted in the relevant traffic channel T and the countdown value is decremented in each subsequent frame. Before the countdown value reaches zero, the groups of receivers S , S retune to the bulletin board channel, receive their new channel allocations and retune to the traffic channel indicated for their group. The frame timings of the different traffic channels T , T are staggered to reduce the peak power required to transmit message bursts in these channels.
