摘要: 3GPP R15版本存在不支持跨SMF服務(wù)區(qū)切換和歸屬地路由等問題,為解決這些問題,R16版本定義了ETSUN技術(shù)。主要介紹ETSUN的需求場景、技術(shù)方案以及通信流程,提出了ETSUN的引入建議以及對R15版本網(wǎng)絡(luò)的增強需求。研究內(nèi)容將對相關(guān)工作者研究ETSUN技術(shù)方案以及對網(wǎng)絡(luò)設(shè)備的技術(shù)要求有一定的幫助。

Abstract: 3GPP R15 does not support handoff cross SMF service area and home routing. To solve this problem, ETSUN which is the one of new features of 3GPP Release 16 is introduced. In this paper ,the application scenes, technical solutions and communication flows are introduced,and recommendating about applying ESTUN and requirement of enhancing present R15 5G network are also proposed. This will be helpful to study ETSUN technical solutions and technical requirements of network equipment.
Key words : inter SMF handover;home routing
0 引言
3GPP R15版本滿足了5G增強移動寬帶(enhanced Mobile BroadBand,eMBB)場景的基本通信需求,3GPP R16提出新的網(wǎng)絡(luò)特性,在進一步完善eMBB能力的同時,也增強了對超可靠低延遲通信(Ultra-relaible and Low Latency Communication,URLLC)場景的支持,提升和拓展了5G網(wǎng)絡(luò)服務(wù)2B和2C的能力,其中包括5G核心網(wǎng)的會話管理功能(Session Management Function,SMF)和用戶面功能(User Plane Function,UPF)拓?fù)湓鰪娂夹g(shù)(Enhancing Topology of SMF and UPF in 5G Networks,ETSUN)特性。ETSUN重點解決了R15版本存在的歸屬地路由問題、用戶跨SMF(會話管理功能)服務(wù)區(qū)業(yè)務(wù)中斷問題以及會話過程中的IP地址分配等問題。
本文將從ETSUN的需求出發(fā),分析ETSUN的技術(shù)方案和通信流程,并提出ETSUN的引入建議和對當(dāng)前R15版本的5G網(wǎng)絡(luò)增強要求。
