Analysis of delay distributions in CDMA mobile switching system

In this paper, we propose a seemingly efficient method computing delay distributions in CDMA mobile switching system. The proposed method is based on queueing network modeling and GPH(generalized phase-type) semi-Markov chain analysis. The class of GPH distributions has several properties which can be applied conveniently for computational purposes. The basic methodology adopted in delay analysis for switching system is explained step by step. Application results are given to demonstrate the accuracy of the method and to verify that the system meets the requirements for delay. The proposed method seems to be very useful to analyze delay distributions in communication systems including switching system.
