Output and Delay Process Analysis of Cellular Mobile Telecommunication Networks with Hand-off

Conclusion

In this chapter, we have presented techniques for analyzing the behavior of hand-off priority schemes. We allocated the total channels to two types of streams (new calls and hand-off calls), and gave hand-off calls a finite buffer-capacity. We presented a matrix-analytic solution to numerically evaluate the performance of the mobile radio network with hand-off stream. A non-priority scheme and a priority scheme were also compared in several cases and trade-offs between performance measures of new calls and hand-off calls were clarified in numerical examples. Using the matrix-analytic solution for the stationary state probability distribution, we further derived the higher moments of waiting time for the hand-off stream.

From the numerical results and discussions we can conclude that to reduce the forced termination of calls in progress, one of the most promising treatments is to make channel reservation and buffer space for hand-off calls. The priority scheme we proposed in this chapter is useful to improve the system performance with hand-off calls.

The analysis presented in this chapter will be not only useful for performance evaluation of the cellular mobile systems with hand-off and the optimum design of the system, but also applicable to performance evaluation of interconnected networks, multichannel networks or integrated networks of voice and data.
