An analytical modeling for a class of queueing priority handoff and call admission control schemes in micro-cellular PCNs
V. Phan-Van, Savo Glisic · 2002
A simple and accurate analysis for performance evaluation and comparison of a class of queueing schemes for priority handoff and call admission control in micro-cellular PCNs presented. The analytical model is developed based on a birth-death process with state-dependent Poisson arrivals, exponentially distributed and decomposed service-time, multiple servers, finite or infinite system capacity and general customer impatience until the beginning of service. The measures of interests include the probabilities of handoff forced terminations, handoff failure and new call blocking. The closed-form solutions are obtained and numerical results are presented for important modeling scenarios. This analysis is believed to have significant uses for network planning and performance optimization.
