Abstract
Systems and methods are disclosed herein that relate to obtaining and using Packet Detection Rules (PDRs) in a cellular communications system operating as virtual Ethernet bridge based on Ethernet forwarding information. In one embodiment, a method performed by a User Plane Function (UPF) for enabling a cellular communications system to operate as a virtual Ethernet bridge comprises obtaining a PDR for a Protocol Data Unit (PDU) session in a downlink direction in the cellular communications system. The PDU session is associated with an egress Ethernet port of the virtual Ethernet bridge for the downlink direction, the PDR maps Ethernet packets received at the UPF on an ingress Ethernet port(s) of the virtual Ethernet bridge to the PDU session associated with the egress Ethernet port of the virtual Ethernet bridge, and the PDR is derived from an Ethernet packet forwarding rule of the virtual Ethernet bridge.
