TD-SCDMA集群系统负荷控制研究与仿真

Analysis and Simulation of Load Control in TD-SCDMA Trunking System

负荷控制是无线资源管理功能的一个重要部分,它可以使系统能够稳定的工作在不过载的状态。文中以TD-SCDMA数字集群系统为研究对象,在传统算法的基础上,提出一种时隙均衡与AMR降速处理相结合的算法。根据小区的干扰水平进行群组的资源分配,最大限度地平衡各个小区的负载情况,充分利用系统的时隙资源,最后通过仿真验证了该算法较其他算法显著改善了系统的性能。

Load control is an important part of radio resource management,it can maintain the system work in a stable condition.In this paper,we propose a load control algorithm combining slot balance and AMR deceleration for TD-SCDMA digital trunking system.Resource allocation of the group users are based on the cell interference level,in order to balance the load of each cell and effiently use the system resources.The algorithm is verified by simulation.It shows that the proposed algorithm can significantly improve system performance compared to other methods.
