초록 ▼

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

대표청구항 ▼

[ What is claimed is:] [1.] A dynamic channel allocation system in which communication is carried out between a radio base station and a radio mobile station by the use of a plurality of channels, each channel being given a priority degree, one of said channels that has a higher priority degree being preferentially allocated to said communication, said system comprising:resetting means for resetting a priority degree modification frequency counter into zero;first making means for making said priority degree modification frequency counter count up by +1 upon every communication request from said radio mobile station;selecting means for selecting as a selected channel a particular channel having a higher priority degree upon every communication request from said radio mobile station;allocating means for allocating said selected channel to each communication request when said selected channel is an idle channel and for increasing said priority degree of said selected channel by a first function determined by the value of said priority degree modification frequency counter;decreasing means for decreasing said priority degree of said selected channel by a second priority function determined by the value of said priority degree modification frequency counter when said selected channel is not an idle channel;judging means for judging whether or not the value of said priority degree modification frequency counter has reached an upper limit value; andsecond making means for making said priority degree modification frequency counter have an intermediate value between zero and said upper limit value, wherein accumulation of a past history is inheritably available for realizing a rapid channel allocation and quickly bringing said priority degree to a stable point with said past history.
