摘要
LTE现网存在L1800、L2100、L900三个频段,其中覆盖最为完善的为L1800,L2100用于热点覆盖,L900用于补充覆盖。多频段组网的挑战是如何确定一套合理的切换策略,最大限度地合理利用网络,提升用户感知。基于多频组网的网络架构,根据语音和数据业务,对带宽、覆盖的不同要求,研究切换参数方案,给出合理的切换策略。
The current LTE network has three bands: L1800, L2100 and L900, Among them, L1800 is the most complete coverage, L2100 is used for hot spot coverage, and L900 is used for supplementary coverage. The challenge of multi-band network is to determine a reasonable Switching strategy that maximizes the use of the network and improves user experience.Based on the network architecture of multi-band networking,research the Switching parameter scheme,finally,according to the requirements of voice and data services for bandwidth and coverage,give a reasonable Switching strategy.
