Mobile networks are witnessing rapid advances in the number of the subscribers and the classes of services (voice, data and multimedia). In order to provide service with high capacity and quality, handoff and the mobility management schemes must be acceptably and optimally implemented. In this paper, various CAC schemes have been investigated and reviewed with mathematical models developed and experiments designed to assess and validate their performance. The analysis in this paper indicates that the majority of the schemes have poor resource utilization because resources are not fully used. Also, the experimental results show that new calls have a higher blocking probability in the non-prioritized scheme which gives more considering to handoff requests. The experience of high call blocking probability of new calls is due to prioritization used.
