Call admission control algorithm for cellular CDMA systems based on best achievable performance

Uplink admission and power control in a CDMA wireless network are investigated. The subject is first reviewed and admission strategies classification is recalled. We propose a feasibility-based call admission control algorithm. This algorithm is compared to a received power-based admission control in a simple simulation. Performance is represented by the grade of annoyance, which is a combination of blocking and dropping probabilities. The best performance of each of the two studied algorithms is evaluated as a function of the offered traffic. The proposed feasibility-based admission control is found to have some performance improvements
