摘　　要：随着4G流量的持续增长,热点区域部署多载频以改善用户感知。随着多载频组网规模的逐步扩大,三载频组网以16.4%的网络规模贡献了33.8%的流量。因此,多载频组网区域的异频切换及重选问题成为移动网络优化的一个重点内容。通过分析UE上报的MR数据来指导切换参数的配置及选择合理的重选参数,使得充分发挥LTE1800/L2100的容量优势,提升网络吞吐率及用户感知。With the continuous growth of 4 G traffic, multi-band are deployed in hot spots to improve user perception. With the expansion of multi-band network scale, its three band network contributes 33.8% of traffic with 16.4% network scale. Therefore,the problem of inter frequency handoverand cell reselection in multi-band region becomes an important content of mobile network optimization. Through the analysis of MR data reported by UE to guide the configuration of handover and reselection parameters, make full use of LTE1800/LTE2100 capacity advantages, improve network throughput and user perception.
