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) se
mi-Markov chain analysis. The class of GPH distributions has several p
roperties 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 demonstra
te 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 switch
ing system. (C) 1997 Elsevier Science Ltd.
