摘　　要：为了解决ULCL方案无法支持漫游和回落4G接入的不足,文章研究并设计了一种以多数据网络名称(Data Network Name, DMN)为基础的5G双域专网分流解决方案。该方案主要在SMF的支持下执行专用DNN会话的创建任务并有效发挥分流规则的约束作用,通过UPF向不同会话锚点对专网和公网流量进行分流,以此实现二者之间的顺畅高效切换。应用效果表明,该方案不仅能够有效支持基于漫游接入的专网与公网分流,还可以在回落至4G网络场景之时实现用户高速接入,具有较理想的应用价值。In order to solve the ULCL scheme cannot support roaming and back 4G access,this paper studies and designs a base 5G double domain private network shunt solution,mainly under the support of SMF to perform dedicated DNN session creation tasks,and effectively play the constraint of diversion rules,through the UPF to different session anchor of private network and public network traffic,to achieve smooth and efficient switching between the two.From the perspective of application effect,this scheme can effectively support the separation between private network and public network based on roaming access.Not only that,it can also realize high-speed access to users when it falls back to the 4G network scene,which has an ideal application value.
