Dynamic channel allocation by using allocation function in PCS

A dynamic channel allocation method applicable to the microcell system such as the personal communications service (PCS) is presented. The factors determining the quality of the channels are analyzed. The allocation function that consists of these factors are defined. The channel allocation for a call is processed by using the function value. While a channel is being allocated to a call, an adequate quality channel is used instead of the best quality channel. The probability of call blocking is decreased even in the cells having a high traffic load.
