中国电信LTE 800M深耕试点实施策略研究

Research on implementation Strategy of China Telecom LTE 800M Deep Cultivation pilot project

为了响应国家加快5G网络部署和网络升级要求,中国电信将加快NB-IOT(窄带物联网)、4G、5G等新型网络应用,目前中国电信LTE网络已正式演进为多频组网,包含1.8G、2.1G及800M,随着VOLTE商用的逐步开展,日渐形成以城区1800M为主力网络,2100M为热点,800M为深度覆盖和主力网热点区域业务分担的网络架构。伴随业务的不断发展,网络容量的负荷压力也日益增长,800M建设之初使用5M带宽的方式已不能满足目前网络需求,为更好利用频率资源全面提升用户体验感知,内蒙古电信呼伦贝尔分公司做为800M深耕试点,有效利用频谱,将5M带宽扩至8.8M,提高了用户感知,达到试点验证预期效果,可借鉴推广。

In response to the national requirement of accelerating 5 G network deployment and network upgrade, China Telecom will accelerate NB-IOT(Narrowband Internet of Things), 4 G, 5 G and other new network applications. At present, China Telecom LTE network has formally evolved into multi-frequency networking, including 1.8 G, 2.1 G and 800 M. With the gradual development of VOLTE’s commercial use, the network architecture with urban 1800 M as the main network, 2100 M as the hot spot, and 800 M as the deep coverage and service sharing in the hot spot area of the main network has gradually formed. With the continuous development of business, the load pressure of network capacity is also growing. At the beginning of 800 M construction, the method of using 5 M bandwidth can no longer meet the current network demand. In order to make better use of frequency resources to comprehensively improve user experience perception, hulunbeier Branch of Inner Mongolia China Telecom took the 800 M deep cultivation pilot and effectively used the spectrum to expand 5 M bandwidth to 8.8 M, improving user perception and achieving the expected effect of pilot verification, which can be used for reference and promotion.
