Channel holding time distribution in public telephony systems (PAMR and PCS)

This paper examines the channel holding time probability distribution in di fferent public telephony systems. The systems analyzed are public access mo bile radio under its two possible operation modes (message and transmission trunking) and personal communications systems. The three statistical studi es are based on a fully empirical approach and make use of data acquired fr om actual working systems that the authors considered to be sufficiently re presentative, Although this empirical approach is obviously highly dependen t on environment, it eliminates the need to assume a number of hypotheses p resent in all analytical and simulation studies. The results achieved throu gh this approach capture effects that others overlook and enrich the existi ng literature on the subject, and should be useful fur teletraffic engineer ing mobile systems.
