ANALYSIS OF CONNECTION DELAY IN CELLULAR MOBILE COMMUNICATION-SYSTEMSUSING DYNAMIC CHANNEL ASSIGNMENT

Dynamic Channel Assignment (DCA), which improves the efficiency of cha nnel use in cellular mobile communication systems, requires finding an available channel for a new call after the call origination. This cau ses the delay which is defined as the time elapsing between call origi nation and completion of the channel search. For system planning, it i s important to evaluate the delay characteristic of DCA because the de lay corresponds to the waiting time of a call and influences service q uality. It is, however, difficult to theoretically analyze the delay c haracteristics except its worst case behavior. The time delay of DCA h as not been theoretically analyzed. The objective of this paper is ana lyzing the distribution and the mean value of the delay theoretically. The theoretical techniques in this paper are based on the techniques for analyzing the blocking rate performance of DCA.
