Abstract: With the development of cloud native, artificial intelligence, big data and other information technologies and the advancement of the trend of cloud-network integration, 6G-oriented wireless networks are moving towards software, intelligence, openness and servitization, achieving in-depth integration of communication and computing, perception and control. Servitization is an important feature of wireless networks to realize the deep fusion of the cloud and networks in services and to empower the endogenous intelligent characteristics of the wireless network. Based on the analysis of the driving force of microservice-based wireless access network, this paper proposes the logical architecture of 6G microservice-oriented wireless access network by drawing support from the existing concepts of 5G core network. And then the paper analyzes the possible future technological evolution directions.
Key words : 6G;service based architecture(SBA),;radio access network(RAN),;service based interface(SBI)

    為實現(xiàn)網(wǎng)絡(luò)功能靈活快速部署和維護(hù),適應(yīng)不同場景的多種業(yè)務(wù)需求,,5G核心網(wǎng)已經(jīng)引入服務(wù)化架構(gòu)(Service Based Architecture,,SBA),網(wǎng)絡(luò)功能(Network Function,,NF)間采用輕量級服務(wù)化接口(Service Based Interface,,SBI),,利用SBA模塊化、無狀態(tài),、獨立化,、扁平化、自主化的優(yōu)勢,,推動網(wǎng)絡(luò)走向開放化,、虛擬化[1]、軟件化和服務(wù)化,。但目前無線接入網(wǎng)(Radio Access Network,,RAN)依舊采用傳統(tǒng)的點對點結(jié)構(gòu),針對未來沉浸式云XR,、全息通信,、感官互聯(lián)、數(shù)字孿生,、元宇宙等新型應(yīng)用[2],,無法很好地支持6G無線網(wǎng)絡(luò)的業(yè)務(wù)需求和技術(shù)演進(jìn)。6G RAN的微服務(wù)化技術(shù)研究是實現(xiàn)網(wǎng)絡(luò)高效彈性,、內(nèi)生設(shè)計,、開放生態(tài)的重要一環(huán),受到學(xué)術(shù)界和產(chǎn)業(yè)界越來越多的重視,。由奧盧大學(xué)科學(xué)基金會領(lǐng)導(dǎo)的6G Flagship指出未來網(wǎng)絡(luò)向真正端到端基于服務(wù)的架構(gòu)演進(jìn)趨勢,,后續(xù)可能會為RAN開發(fā)類似于5G核心網(wǎng)的SBA框架[3]。歐盟5G基礎(chǔ)設(shè)施協(xié)會認(rèn)為借助6G,,SBA有望實現(xiàn)全網(wǎng)全平面,、端到端的擴(kuò)展,包括核心網(wǎng),、RAN和終端,,提供更大的部署和操作靈活性,支持網(wǎng)絡(luò)的網(wǎng)絡(luò)和系統(tǒng)的系統(tǒng)概念,,以便于子系統(tǒng)集成和可擴(kuò)展性[4],。中國IMT-2030(6G)推進(jìn)組則將基于服務(wù)化的體系結(jié)構(gòu)、云原生實現(xiàn)的網(wǎng)絡(luò)虛擬化,、微服務(wù)架構(gòu)等作為可編程網(wǎng)絡(luò)的重要使能因素,,構(gòu)成面向6G的控制面可編程和用戶面各網(wǎng)元端到端可編程網(wǎng)絡(luò)架構(gòu),增強敏捷性和靈活性,,為消費者提供創(chuàng)新的通信服務(wù)[5],。因此,有必要深入研究面向6G的微服務(wù)化RAN架構(gòu)及關(guān)鍵技術(shù),,綜合來看其必要性如下:
