Abstract

In a dynamic channel allocation system, upon every communication request, selection is made of a channel having a maximum priority degree (step 1004). Judgement is made about whether or not the channel is an idle channel (step 1005). If it is an idle channel, its priority degree P is increased by a priority function .DELTA.P(x) determined by a priority degree modification frequency x and this channel is allocated (steps 1006 and 1007). If it is not an idle channel, the priority degree P is decreased by the priority function .DELTA.P(x) (step 1008). Subsequently, the priority degree modification frequency x is increased by +1. When x reaches an upper limit value xo, the priority degree modification frequency x is not reset but is given as x=xl<xo.
