Call/mobility processing capacity of the personal communication exchange

We analyze the call processing capacity of a personal communication exchang e (PCX) for various call types (local, outgoing, incoming and transit calls ). We also analyze the mobility processing capacity of the PCX for mobility functions (handover and location registration). The call/mobility processi ng capacities are calculated by simulation on a queueing network model. The delay times in the processing of call and mobility functions are also calc ulated by simulation and queueing network analyzer (QNA) for comparison bet ween the two methods. We focus our analysis on the PCX system with distribu ted call/mobility processing structure, which has been under development in Korea. The numerical computations show that the results from the simulatio n and QNA are in closer agreement when the utilization rate (the faction of time a processor is busy) of processor handling the mobility functions bec omes lower. It is estimated that the call processing capacity of the PCX is 421,280 busy hour complete call (BHC) which is equivalent to 150,700 subsc ribers of 1.6 BHC. The handover and location registration processing capaci ties are calculated to be 26,000 transactions/hour and 406,000 transactions /hour, respectively.
