摘要: 在3GPP Release 15阶段,服务化架构项目主要完成了服务发现的机制,但网元间通信采用的还是直接通信方式,这种点对点的通信方式在未来复杂的网络环境中极难维护,同时网元本身的可靠性也没有成熟的保障手段。主要研究5G核心网服务化架构演进方向,具体分析基于服务通信代理的间接通信方式,给出服务通信代理的优势与部署建议;分析网元集合与网元服务集合的高可靠性机制,给出网元卸载存储、转发功能以及专注计算的演进方向。

Abstract: In 3GPP release 15, service-based architecture work item mainly finished the mechanism of service discovery. However, communication between network functions is still in a direct way which adopts point-to-point pattern and is hard for operations in future complicated network environment. At the same time, there is no mature protecting measure for the reliability of network functions. This paper mainly studies on the evolution of service-based architecture in 5G Core. More specifically, it analyzes the indirect communication method based on service communication proxy and gives the advantages and implementation suggestions. Also, it analyzes the high reliability mechanism of the network function set as well as the network function service set and gives the evolution of network functions as focusing on computing and removing the functionalities of storage and switching.
Key words : service-based architecture;5G Core

    服務(wù)化架構(gòu)[1](Service-based Architecture,SBA)是第五代移動(dòng)通信系統(tǒng)(5G)核心網(wǎng)的重要特征。SBA在第三代合作伙伴計(jì)劃(the 3rd Generation Partner Project,3GPP)Release 15階段首次被提出,主要將網(wǎng)絡(luò)功能劃分為可重用的若干個(gè)服務(wù),并且在服務(wù)之間使用輕量化接口通信,目標(biāo)是實(shí)現(xiàn)5G系統(tǒng)的高效化、軟件化與開放化。在3GPP Release 16階段,服務(wù)化架構(gòu)增強(qiáng)(enhanced Service-based Architecture,eSBA)項(xiàng)目在SBA的基礎(chǔ)上繼續(xù)增強(qiáng)了服務(wù)間通信的靈活性與可靠性。本文主要研究實(shí)現(xiàn)eSBA的關(guān)鍵技術(shù)與未來5G核心網(wǎng)基于SBA架構(gòu)的演進(jìn)方向。
