We also analyze the mobility processing capacity of the PCX for mobility functions (handover and location registration). The call/mobility processing capacities are calculated by simulation on a queueing network model. The delay times in the processing of call and mobility functions are also calculated by simulation and queueing network analyzer (QNA) for comparison between the two methods. We focus our analysis on the PCX system with distributed call/mobility processing structure, which has been under development in Korea. The numerical computations show that the results from the simulation and QNA are in closer agreement when the utilization rate (the faction of time a processor is busy) of processor handling the mobility functions becomes 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 subscribers of 1.6 BHC. The handover and location registration processing capacities are calculated to be 26,000 transactions/hour and 406,000 transactions/hour, respectively.
