%X Call Admission Control(CAC) plays an important part in radio resource management in wireless communication networks.It permits or denies the call arrival connection requests based on the certain criteria.The design of CAC has direct impact on the network performance and resource unitization.CAC schemes have been widely investigated during the last two decades,which greatly improves the network performances,such as call blocking and dropping probabilities,packet delay,loss rate,and throughput.Related background knowledge about CAC in wireless communication networks and its requirements and functions were introduced.Some recent research results on CAC schemes were outlined with great emphasis.The problems or drawbacks in current schemes were pointed out.Finally,ideas for further research were discussed.
