摘要： Embodiments of the present disclosure provide a method, a network node, and a computer program product for transmission of a response message, in a wireless communication system (100). The method is performed by a network nod (50) of an access network (102) in the wireless communication system (100). The method comprises receiving (302) time- sensitive communication assistance information, TSCAI, including TSC configuration parameters from a session management function, SMF. Further, the method comprises transmitting (304) a response message intended for one or more of: at least one network function associated with a core network, CN (104), and an application function, AF, said response message indicating whether or not the network node satisfies the TSC configuration parameters in the TSCAI. Corresponding network node, and computer program products are also disclosed.

摘要： A method by a first node (111) for configuring a second node (112) to handle ingress member flows (121, 122) split from a flow of packets, via at least one elimination function (131), and one replication function (132). The first node (111) and the second node (112) operate in a communications network (100). The first node (111) allocates (601) a first indication to a first ingress member flow (121) to be input into the elimination function (131). The first indication identifies the first ingress member flow (121) as being comprised in the flow of packets. The first indication uniquely identifies the first ingress member flow (121) from at least one of: i) a second ingress member flow (122) to be input into the replication function (132), and ii) any other ingress member flow to be input into the second node (112). The first node (111) configures (602) the second node (112) to use the allocated first indication.

摘要： 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.

摘要： Systems and methods are disclosed herein that relate to a cellular communications system that operates as a virtual Ethernet bridge(s). Embodiments of a User Equipment (UE) for a cellular communications system and corresponding methods of operation of a UE are disclosed. In some embodiments, a UE for a cellular communications system, where the cellular communications system operates as multiple Ethernet network virtual bridges, comprises one or more transmitters, one or more receivers, and processing circuitry associated with the one or more transmitters and the one or more receivers. The processing circuitry is configured to cause the UE to establish a first Protocol Data Unit (PDU) session to an Ethernet network via a first User Plane Function (UPF), wherein PDU sessions that connect to the Ethernet network via the first UPF are grouped into a first Ethernet network virtual bridge. In this manner, shared media in the Ethernet network can be avoided.

摘要： System and methods for providing session context storage during session re-establishment are provided. In this regard, embodiments of a method for providing a Session Management Function (SMF) in a core network to enable storage and retrieval of User Equipment (UE) context data for a current Protocol Data Unit (PDU) comprises determining that the current PDU session should be released and subsequently re-established, saving the UE context data maintained at the SMF for the current PDU session into a UE context database, and initiating a release of the current PDU session. In another embodiment, a method comprises an SMF retrieving UE context data associated with a prior PDU session from a UE context database, and initiating establishment of the new PDU session based on the UE context data. In this manner, a subsequent PDU session for the UE may be established more efficiently using the UE context data.

摘要： A node (110, 120) of a data network classifies data packets into multiple different classes. Further, the node (110, 120) determines those of the classes which have zero traffic load. Depending on the classes which have zero traffic load, the node (110, 120) decides for at least one of the other classes between transmitting the data packets of the class as guaranteed data packets which are subject to a guarantee of not being dropped and not delayed by more than a certain delay limit and transmitting the data packets as non-guaranteed data packets which are not subject to the guarantee.

摘要： A network (NWl) has switches (S1-S7), routers (R1-R4) and a management node (NMSl) interconnected by links (PLl) in a spanning tree (STl) and links (PL2) to blocked interfaces. Switches and routers have the IP address of the management node. The nodes are discovered by the management node (NMSl) broadcasting a ping message (PiI) and on reply (RPiI) adds the nodes to the topology. The spanning tree (STl) is discovered in that the management node retrieves address forwarding tables from the switches and assigns them a ranking value. From the highest ranked node successively lower ranked nodes are connected. The blocked interfaces (PL2) are discovered by configuring a VLAN (VLANl) to include only the spanning tree (STl) and disabling the latter. The blocked interfaces are turned off and on, matching link down traps are noted and the corresponding link (PL2) is discovered. The status of the interfaces (1, 2, 3...) are cyclically checked for changes and new links and network segments are added. Only basic management features of the switches are needed and all nodes and links are discovered.

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.
