LTE中一种基于负载均衡的自优化切换算法
A Self-Optimization Handover Algorithm Based on Load Balancing for LTE Networks
摘要
Abstract
In the self-organizing network (SON) of 3GPP LTE ,the algorithms dynamically adjusting many parameters to-gether are better than those adjusting only one parameter .EWPHPO algorithm can not dynamically adjust the handover parameters and the load of the individual cell timely ,which causes the dropping probability not to be controlled effectively .In this paper ,the WPLBHO algorithm was suggested to improve the EWPHPO algorithm in order to solve these problems .The numerical results were given and compared with those from the EWPHPO algorithm under the same simulation conditions .It is shown that the dropping probability and the ping-pang ratio decrease about 20% and 5% ,respectively ,but the handoff failure rate hardly vary .Then the total performance of the system increases about 25% .On the other hand ,the average load time decreases about 50% .These show that the total performance of the system is evidently improved through our algorithm .关键词
