摘　　要：3GPP R15版本存在不支持跨SMF服务区切换和归属地路由等问题,为解决这些问题,R16版本定义了ETSUN技术。主要介绍ETSUN的需求场景、技术方案以及通信流程,提出了ETSUN的引入建议以及对R15版本网络的增强需求。研究内容将对相关工作者研究ETSUN技术方案以及对网络设备的技术要求有一定的帮助。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 R155G network are also proposed.This will be helpful to study ETSUN technical solutions and technical requirements of network equipment.

关 键 词：跨SMF切换 归属地路由
