摘　　要：全IP化是未来通信系统发展的必然趋势。为了体现IP传输的优势,基于IP的无线接入网络(IP RAN)的性能和传输效率是必须考虑并正视的问题。本文分析了IP RAN可能存在的性能瓶颈,并从拥塞控制的角度对呼叫接入控制和负载均衡两种性能改善策略进行对比。针对基站与网络控制器的IP RAN传输,提出一种改进的负载均衡方案,引入小区业务度的概念,并以此参量为基础,动态调整呼叫与RNC的连接关系。该方案更有效的利用了网络资源,改善系统性能。All-IP is an inevitable trend for future communicating system. In order to show the advantage of IP transmission, the performance and transmission efficiency are two necessary issues in the IP-based radio access networks （RAN）. This paper analyzes the possible performance bottleneck in the IP RAN, and compares call admission control and load balance these two policies from the perspective of congestion control. Based on the IP transmission for RAN, a concept for the cell＇s traffic load is introduced, according to which the relationship between call and RNC is adjusted. The new policy makes use of the network more efficiently, and improves the system＇s overall performance.
