Effects of call arrival rate and mobility on network throughput in multi-cell CDMA

The effect of call arrival rate on the capacity of a code-division multiple-access (CDMA) cellular network is evaluated. First the inter-cell and intra-cell interferences of every cell on every other cell are calculated for a given network topology. Then the capacity region for the number of simultaneous calls in every cell is defined for specified system parameters. This region is used to evaluate the new call blocking and handoff call blocking probabilities. The network throughput is found by considering the revenue generated by accepting a new call and the cost of a forced termination due to handoff failure. Implied costs are calculated for both high and low mobility of calls between cells, and the effect of mobility on pricing is discussed. Implied costs are used to maximize the throughput with respect to the call arrival rates by applying a gradient descent algorithm
