摘要
5G核心网的云化旨在重构虚拟化的开放网络,通过提供开放的网络能力来满足差异化的需求。目前运营商在现网部署时仍主要采用软硬二层解耦的架构,难以实现全网资源共享。5GC三层解耦网络试商用案例,首先在NFV基础设施层当中的硬件资源层、虚拟化层和NFV虚拟网络层等三层之间实现解耦,其次采用中国电信自研和其他多供应商共同部署模式,对项目实施过程中多供应商协同配合方面出现的问题进行分析并提出解决方案,最终目的是推动更加开放和完善的5G核心网三层解耦方案大规模商用。
The cloud-based 5G core network aims to reconstruct virtualized open networks by providing open network capabili⁃ties.operators still mainly use a soft and hard two-layer decoupling architecture when deploying in the current network,making it diffi⁃cult to achieve resource sharing across the entire network.Trial commercial case of 5GC three-layer decoupling network,decoupling is achieved between the hardware resource layer,virtualization layer,and NFV virtual network layer in the NFV infrastructure layer,adopting China Telecom's self-developed and multi supplier joint deployment model,Analyze and propose solutions to the problems that arise in the collaborative cooperation of multiple suppliers during the project implementation process,The ultimate goal is to pro⁃mote a more open and comprehensive 5G core network three-layer decoupling solution for large-scale commercial use.
