摘　　要：5G时代专线业务呈现出新的形态,同一客户的应用可能分布在全国2个以上节点,要求用户漫游时能就近接入企业应用。首先分析了业务诉求及专线业务网络侧基本实现方案,进而深入研究5G服务化架构的本质特性,提出利用3GPP R16定义的ServingScope字段或新增虚拟VNF模拟注册服务等方式实现专线业务的就近接入,最后分析了5G用户4G接入场景下的专线就近接入实现方案。In the 5G era,the private line service presents a new form.The application of the same customer may be distributed in more than two nodes in the country,which requires the roaming users to access the enterprise application nearby.Firstly the ser-vice demands and the basic implementation scheme of the network side of the private line service are analyzed,and then the essential characteristics of the 5G service architecture are deeply studied.It is proposed to realize the nearby access of the private line service by using the serving scope field defined by 3GPP R16 or the new virtual VNF simulated registration service.Finally,the implementation scheme of the nearby access of the private line service under the 4G access scenario of 5G users is analyzed.
