摘要： 从运营商收入的角度出发，提出一种基于收入值的呼叫接纳控制算法，并采用改进型启发式贪婪算法进行求解。仿真结果表明，该算法可以满足WiMAX网络多服务要求。在带宽资源有限的条件下，考虑高付费业务的公平性，在保证基于收入值的业务QoS的情况下，增加运营商的收入，实现收入最大化。

Abstract: According to the requirements which the service providers desire to increase their services’ revenue, a novel Revenue-based Call Admission Control Algorithm(RCACA) is proposed and solved by the improved heuristic greedy algorithm. The simulation results show that RCACA can meet the requirements of more services in World interoperability for Microwave Access(WiMAX) networks and guarantee the fairness of high-paying services and the revenue-based QoS under the condition of limited bandwidth resources. Furthermore, the service providers’ revenue can be increased and reaches the maximum.
