Abstract: 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 supervision.
