  • Patent number: 11882033
    Abstract: Systems and methods are disclosed herein for filtering Ethernet device source addresses for loop avoidance in a cellular communications system. Embodiments of a method performed by a User Plane Function (UPF) in a core network of a cellular communications system and corresponding embodiments of a UPF are disclosed. In some embodiments, a method performed by a UPF in a core network of a cellular communications system comprises obtaining a Medium Access Control (MAC) address that is reachable over a particular Protocol Data Unit (PDU) session. The method further comprises installing, at the UPF, a filtering rule that prevents Ethernet frames having the MAC address as a source address from being delivered by the UPF via downlink on the particular PDU session. In this manner, loopback of Ethernet frames on the PDU session is avoided.

  • Publication number: 20230336489
    Abstract: A method by a first node for configuring a second node to handle ingress member flows split from a flow of packets, via at least one elimination function, and one replication function. The first node and the second node operate in a communications network. The first node allocates a first indication to a first ingress member flow to be input into the elimination function. The first indication identifies the first ingress member flow as being comprised in the flow of packets. The first indication uniquely identifies the first ingress member flow from at least one of: i) a second ingress member flow to be input into the replication function, and ii) any other ingress member flow to be input into the second node. The first node configures the second node to use the allocated first indication.

  • Publication number: 20230327999
    Abstract: A method performed by a node, for handling one or more member streams split from a stream of frames. The node supports at least replication function and one elimination function, to process the one or more member streams. The node operates in a communications network. The node assigns an indication to a frame of one or more frames comprised in a first member stream outgoing from the at least one elimination function. The indication is the same in every frame of the one or more frames. The indication identifies the first member stream as an output member stream in the stream. The node forwards the first member stream outgoing from the at least one elimination function, identified by the indication, to another function supported by the node, or to another node.

  • Publication number: 20230239174
    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.

  • Publication number: 20220368626
    Abstract: Systems and methods for packet or frame replication and elimination in a Time Sensitive Networking (TSN) network or Deterministic Networking (DetNet) network are disclosed. In some embodiments, a method of operation of a node in a TSN network or DetNet network comprises determining whether to reset a sequence recovery function used for frame or packet elimination for a particular stream of packets based on either or both of an explicit indication or an implicit indication and resetting the sequence recovery function used for frame or packet elimination for the particular stream of packets upon determining to reset the sequence recovery function. In this manner, packet or frame elimination is improved by avoiding scenarios that result in discarding valid packets or frames due to an out of sync condition between the sequence generation function at the replicator and the sequence recovery function at the eliminator.

  • Publication number: 20220272031
    Abstract: A method for establishing a Protocol Data Unit (PDU) Session(s) is disclosed. In examples disclosed herein, a device (e.g., a wireless device) uses a unique Port Number(s) (e.g., an internal physical or logical Port Number) to search for a matching User Equipment (UE) Route Selection Policies (URSP) rule(s) having a Traffic Descriptor(s) that matches the unique Port Number(s). The device then determines whether there exists a matching PDU Session(s) associated with a Route Selection Descriptor(s) of the matching URSP rule(s). Accordingly, the device can reuse the matching PDU Session(s) in a presence of the matching PDU Session(s) or establish a new PDU Session(s) in an absence of the matching PDU Session(s). By using the unique Port Number(s) as the Traffic Descriptor(s) in the URSP rule(s), it is possible to simplify configuration of the device, especially for redundant traffic handling.
