摘　　要：3G业务的多样性、QoS的严格性以及无线资源的稀缺性等因素对呼叫接纳控制技术提出了更高的要求。改进了一种支持多业务的基于接收功率的接纳控制算法。针对原有算法中使用单一判决门限产生高阻塞率的问题,引入可占用总功率的最大比例,根据不同的业务需求,较好地解决了这种问题。此算法可以进行网络优化处理,可以通过挂起或强制拆除不重要的数据业务呼叫,优先接入新到达的切换话音呼叫。Call Admission Control （CAC） technology is an important function entity, which is expected to support muhi-calss services, satisfy strict requirement of QoS and solve the problem of scarcity of radio resource, in order to keep the covered area and the system robustness. This paper presents multi-class services RP-CAC arithmetic（MSRP-CAC） which introduces as the most proportion which service can engross, sets service threshold for each traffic to ensure priority. The simulation results show that it can improve the system performance effectively.
