摘要： Systems and methods are disclosed related to exposure of redundant transmission in a cellular communications system. In one embodiment, a method performed by a network node for customization of redundancy for network traffic flows comprises obtaining, from a network entity, data indicative of a requested degree of redundancy for a network traffic flow and, based at least in part on the requested degree of redundancy, performing adjustments to one or more network redundancy mechanisms of a plurality of network redundancy mechanisms for the network traffic flow. In this manner, by exposing redundant transmission to the network entity, the network entity is enabled to request customization of redundancy mechanisms to provided the requested degree of redundancy for a network traffic flow.

摘要： Time-Sensitive Networking (TSN) domains (30) include centralized entities (32, 34) for establishing and managing intra- and inter-domain TSN streams, with the inter-domain TSN streams based on an advantageous approach to inter-domain advertisement of respective end stations (40) operating as talkers and listeners. Based on exploiting and extending talker/listener messaging, inter-domain listener information returned to the TSN domain (30) of a given talker aggregates the status of TSN stream establishment with respect to each listener in each external TSN domain (30) that includes one or more end stations (40) interested in acting as listeners, and with respect to each external TSN domain (30) used to carry the TSN stream. Correspondingly, the configuration of network resources in the respective TSN domains (30) is made to depend on the exchanged status information.

摘要： A PDU ordering function (POF) restores the proper order of PDUs in a stream, at the Layer-2 or 3 level of a TSN or DetNet. The sequence number of the last PDU forwarded is stored, and compared to the sequence number of a newly received PDU. If the new PDU is an earlier or the "next" PDU in the stream, it is forwarded and the value of the last PDU forwarded is updated. If the newly received PDU is two or more sequence numbers ahead of the last PDU forwarded, it is buffered. Other PDUs are received and processed, and the value of the last PDU forwarded is updated. When the buffered PDU is the next one to the last PDU forwarded, it is retrieved from the buffer and forwarded. To bound the total latency the POF can impose on aPDU stream, a predetermined maximum buffering time timer is started upon buffering the PDU. If the timer expires before the buffered PDU becomes "next" to the last PDU forwarded, it is nevertheless retrieved and forwarded.

摘要： 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.

摘要： Systems and methods are disclosed herein that relate to reporting a multicast Medium Access Control (MAC) address used by a particular Protocol Data Unit (PDU) session in a cellular communications system. In some embodiments, a method performed in a core network of a cellular communications system comprises, at a User Plane Function (UPF), obtaining multicast MAC address information comprising a multicast MAC address to be used on a particular PDU session and information that identifies either or both of a User Equipment (UE) associated with the particular PDU session and the particular PDU session and reporting, to a Session Management Function (SMF), use of the multicast MAC address on the particular PDU session. The method further comprises, at the SMF, receiving the report from the UPF, and using the multicast MAC address to perform one or more operational tasks.

摘要： The present invention relates to a cellular radio communications system and especially a method, a mobile station and a base station for a smooth hard handover. The smooth hard handover includes preparing radio links in selected base stations for potential communication with a mobile station. This is similar to selecting base stations for the active set in the prior art soft handover. A difference is though that just one radio link is actively used for transmission. The handover from the active to a prepared radio link is quick and safe, as compared to conventional hard handover, because of the preparation, while requiring a less complex system architecture then the conventional soft handover. The smooth hard handover can replace the soft handover.

摘要： Systems and methods for control signaling between Third Generation Partnership Project (3GPP) network entities and a transport network are disclosed herein. In some embodiments, a method performed by a first network node comprises receiving a configuration that indicates information for a particular tunneling encapsulation header to be used for a particular Quality-of-Service (QoS) flow. The particular QoS flow is a QoS flow to which a delay-sensitive stream is mapped. The method further comprises receiving traffic for the particular QoS flow, encapsulating the traffic with the particular tunneling encapsulation header to provided encapsulated traffic, and transmitting the encapsulated traffic to a second network node via a transport network.
