Wireless/mobile communication systems are becoming increasingly popular in recent years. As the wireless resources are scarce, it is important to allocate resources efficiently and carefully, in order to achieve maximum output. The call admission control schemes play a significant role in providing the desired Quality of Service (QoS) by judiciously assigning the radio channels that are available in a micro cell. In this paper, the authors present two Call Admission Control (CAC) schemes for wireless mobile network, Prioritized Call Admission Control (PCAC) scheme (S1) and Prioritized call admission control scheme with releasing function (S2).
