摘要
5G阶段移动核心网引入新型架构,对5G组网和4G/5G共存演进产生影响。首先介绍了5G核心网架构和组网标准化最新进展,随后对独立组网和非独立组网方案的差别进行了分析,最后提出了5G部署初期独立组网的部署方案。
The introduction of new architecture into the core network has impacts on both the evolution of 5G networks and the coexistence between 4G and 5G. Firstly, the latest advances of 5G core network architecture and networking standardization are elaborated. Then, the difference between the standalone and non-standalone scheme is analyzed. Finally, the standalone deployment scheme at the early stage of 5G is presented.
