4G/5G网络融合演进探析

Analysis on the Evolution of 4G/5G Network Convergence

随着5G SA网络的商用部署,5G与4G协同演进是运营商十分关心的迫切问题。首先,分析了EPC网络为何将长期存在,提出5GC与EPC融合组网是移动核心网的中长期架构,随后,重点分析EPC网络如何与5GC网络协同演进发展,探讨了MME、DRA等EPC网元的演进路径,同时考虑了后续EPC网络的部署形态,为未来的移动网络演进做出有益的探讨。

With the commercial deployment of 5G SA network,the collaborative evolution of 5G and 4 G is an urgent issue that operators concern.This paper first analyzes why the EPC network will exist for a long time,and proposes that the convergence network of 5GC and EPC is a medium-and long-term architecture for the mobile core network.Then how EPC network cooperatively evolves with 5GC network is emphatically analyzed,and the evolution path is discussed for the EPC network elements such as MME and DRA.Finally,the deployment form is considered for subsequent EPC networks,which provides a beneficial discussion for the future mobile network evolution.
