摘要: 在3GPP Release 15階段,服務化架構(gòu)項目主要完成了服務發(fā)現(xiàn)的機制,,但網(wǎng)元間通信采用的還是直接通信方式,,這種點對點的通信方式在未來復雜的網(wǎng)絡環(huán)境中極難維護,同時網(wǎng)元本身的可靠性也沒有成熟的保障手段,。主要研究5G核心網(wǎng)服務化架構(gòu)演進方向,,具體分析基于服務通信代理的間接通信方式,給出服務通信代理的優(yōu)勢與部署建議,;分析網(wǎng)元集合與網(wǎng)元服務集合的高可靠性機制,,給出網(wǎng)元卸載存儲、轉(zhuǎn)發(fā)功能以及專注計算的演進方向,。

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

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