Abstract: Embodiments of the present disclosure provide methods and apparatuses for session management. A method comprises receiving from a user equipment (UE) a request for establishing another session to a data network identified by a data network identification. At least one existing session of the UE has been established to the data network. The method further comprises checking whether the subscription data or the policy data for the UE includes a first indication which indicates that a same session management node for multiple sessions to the data network identified by the same data network identification is required. The method further comprises selecting the same session management node as the at least one existing session for the UE when the subscription data or the policy data includes the first indication. The method further comprises sending a session establishment request to the selected session management node.

Abstract: A method of updating a background data transfer, BDT, policy negotiated between an application function, AF, and a Core Network, CN, is disclose. The method is performed by a Policy Control Function, PCF, of the CN and comprises determining updated BDT policy information including updated conditions for the negotiated BDT policy and at least one candidate BDT policy for the AP to select when the PCF determines that the negotiated BDT policy is affected by degraded network performance. The determined updated BDT policy information is then sent to the AF by the PCF using notification type interaction, thereby effectively updating the negotiated BDT policy.

Abstract: Systems and methods are disclosed herein that relate to Time Sensitive Communication (TSC) to Fifth Generation (5G) Quality of Service (QoS) mapping and associated QoS binding. In one embodiment, a method for QoS mapping in a 5G System (5GS) for a virtual Time Sensitive Networking (TSN) bridge comprises, at a first network function, obtaining information from a TSN Application Function (AF) comprising baseline TSC QoS parameters and one or more additional parameters comprising either or both of: (a) one or more additional TSC QoS attributes and (b) one or more additional traffic attributes. The method further comprises, at the first network function, generating one or more Policy and Charging Control (PCC) rules based on the obtained information and providing the one or more PCC rules to a second network function. The method further comprises, at the second network function, performing QoS binding based on the one or more PCC rules.

Abstract: Systems and method are disclosed herein that relate to support for virtual Time-Sensitive Networking (TSN) bridge management, Quality of Service (QoS) mapping, and TSN related scheduling in a cellular communications system. In some embodiments, a method performed by one or more network nodes of a cellular communications system operating as a virtual TSN bridge of a TSN network comprises providing, to a controller associated with the TSN network, parameters that relate to capabilities of the virtual TSN bridge. The parameters that relate to the capabilities of the virtual TSN bridge comprise a first parameter that defines a clock accuracy of an entity in the cellular communications system that operates gating control for the virtual TSN bridge and a second parameter that informs the controller associated with the TSN network that the virtual TSN bridge or a particular egress port of the virtual TSN bridge is restricted to exclusive gating.

Abstract: Methods, a policy server (110) and a traffic steering server (120) for managing traffic steering policies for steering of traffic of a user equipment are disclosed. The policy server (110) generates (A020) a policy request, wherein the policy request comprises the traffic steering policies, wherein the traffic steering policies include a first traffic steering policy and a second traffic steering policy, both the first and second traffic steering policies being applicable to the traffic in one direction with respect to the user equipment. The policy server (110) sends (A030) the policy request to the traffic steering server (120). The traffic steering server (120) applies (A070) at least one of the first and second traffic steering policies to manage the traffic. Corresponding computer programs and computer program carriers are also disclosed.

Abstract: In scenarios where the quality of service is negotiated through a signalling layer whereas the services are actually carried through a bearer layer, application functions at the signalling layer are not always aware of how quality of service is individually accomplished at the bearer layer on a service basis. The invention provides a method and devices whereby events are detected on a service data flow basis at a detection device in the bearer layer and notified towards an application device in the signalling layer via a control device between the signalling and the bearer layer. The list of events to be notified is obtainable at the control device from the application device and is included in Quality of Service related rules, along with service data flow filters. This Quality of Service related rules are provided to the detection device for inspecting individual service data flows in order to detect and notify the indicated events.

Abstract: Systems and methods are disclosed for supporting traffic management capabilities under network control. In one embodiment, a method performed by a wireless communication device comprises receiving one or more User Equipment (UE) Route Selection Policy (URSP) rules from a network node, receiving traffic control information associated to the one or more URSP rules, and performing one or more actions based on the one or more URSP rules and the traffic control information. In this manner, the network is given control of slice traffic management such that the network can force the UE to perform an action(s) when the network thinks that such action(s) is beneficial.
