摘　　要：时分同步的码分多址技术(TD-SCDMA)网络具有显著的特点,如:可移动性、高速数据传输、业务种类丰富以及业务流量大等,因此,监管TD-SCDMA网络必须能够线速处理所有用户信息.本文以Hayat研究的随机时延的分布式动态负载平衡模型为基础,设计了局域网环境下计算随机时延的负载转移时延模型,采用多次先验仿真的方法确定了增益因子,改进了负载平衡机制以满足3G监管的要求.经过仿真测试,改进后的算法不仅节省了分布式系统的资源,同时还能保证系统稳定、有效地运行,适于TD-SCDMA网络的监管.TD-SCDMA （time division synchronous code division multiple access） network has its prominent characteristics： mobility, high transfer speed, a great varity of services and great traffic flow. So the TD-SCDMA network supervision must process all user information synchronously. Based on Hayat＇s research on a dynamic time delay model for load balancing in distributed system, this paper designs a load-transfer delay model for compute load-transfer delay in LAN （local area network）, defines the gain coefficient by a number of pre-simulation test, and improves load balancing mechanism to meet requirements of 3G supervision. According to the simulation test, the improved algorithmn not only saves the resources of distributed system, but also realizes a reliable and effective operation of the systems. So the improved algorithm is suitable for the TD-SCDMA network suoervision.
