高铁场景基于多频组网的异频切换优化研究

Research on Inter-frequency Handoff Optimization Based on Multi-frequency Networking in High-speed Railway Scenario

随着LTE网络规模不断扩大,一些区域存在多个频段共存的现象。针对LTE多频段组网如何协同的问题,文章以京广高铁为例,提出了一种让用户在大带宽频段网络快入慢出切换优化试验方案,该方案能够减少不必要的异频切换,提高大带宽网络的占用率,更好地提升用户体验。

As the scale of LTE networks continues to expand,multiple frequency bands coexist in many areas.Aiming at the problem of how LTE multi-band networking is coordinated,the article takes the Beijing-Guangzhou high-speed rail as an example and let users quickly switch to broadband network and slowly switch to narrowband network.This solution can reduce unnecessary inter-frequency switching,increase the occupancy rate of high-bandwidth networks to improve user experience.
