摘　　要：第三代移动通信系统TD-SCDMA是一种自干扰的系统。随着未来用户的增加,在无线资源相对有限的情况下,有效控制干扰的要求越来越高,而呼叫接纳控制技术(CAC)就是解决这一问题的关键技术之一。该文提出了基于功率控制的呼叫接纳控制算法,以小区负荷因子为分析参数,分析新用户满足接纳请求的条件,进而对新的呼叫请求作出判断。该算法充分考虑了系统中各种干扰,更加符合实际的网络环境,同时满足了无线用户日益提高的QoS要求。The third generation mobile telecommunication system TD-SCDMA is a self-interference system. As users increasing, a better control of interference is required in this relatively finite cellular network. The call admission control （CAC） is one of the key techniques for solving these problems. In this paper, a call admission control arithmetic based on power control is proposed and the cell load factors are used to analyse the conditions of admission reqrest that new users need, and to make judgment to the new call request. The algorithm gives full consideration to all kinds of interference in the system, and it is more in line with the actual network environment. At the same time, it can satisfy user＇s increasing demand of QoS.
