如果PDU会话的DNN(Data Network Name)对应于LADN(Local Area Data Network)并且I-SMF被插入PDU会话,则SMF应释放或拒绝PDU会话。 在体系架构中添加I-SMF 当具有建立的PDU会话的UE不在由该PDU会话的SMF服务的TA中时,AMF将中间(intermediate)SMF(称为I-SMF)插入PDU会话的信令路径中,以控制终止与5G接入网的N3接口的...
基于5G核心网的CUPS 架构，UPF可以灵活部署到网络边缘的MEC系统，对MEC而言，UPF是分布式的、可配置的数据平面。MEC可在中心云或边缘云提供服务，因此SMF对UPF 的选择、管理以及流量规则配置起到关键作用，SMF允许MEC作为5G应用功能管理PDU会话、控制策略设定和流量规则。在5G网络中部署MEC时，数据平面角色由UPF担任，...
Recent 3GPP enhancements include enhancing topology of SMF and UPF in 5G Networks.The present document proposes methods for enabling such enhancements in case a SMF is not able or it is not allowed to control UPF(s) throughout the same PLMN. For example, in large countries the network may ...
UPF 作为 5G 核心网的用户面网元,主要功能是响应 SMF 请求,作为 RAN 与 DN 之间的联接点,PDU Session 锚点负责完成用户面上 GTP-U 协议的封装与解封装、分组路由与转发、数据包检查以及 QoS Flow 映射等网络用户面的处理,完成用户面门控、重定向、流量转向等策略规则的实施。同时,还要对计费及合法拦截提供用户...
