Abstract: A method, apparatus and computer program product are provided herein to receive, from a source, performance requirements, and cause transmission, to a network, of a request to influence time sensitive communications (TSC) configuration parameters. For example, a method is provided to in response to the request to influence TSC configuration, receive, from the network, network configuration and radio access network (RAN) resource constraints and determine a quality of service (QoS) and the TSC configuration parameters to support a TSC data stream based on the performance requirements received from the source, the network configuration, and the RAN resource constraints. The method is further configured to cause transmission of the determined QoS and the TSC configuration parameters to the network and the source and in an instance the network accepts the determined QoS and the TSC configuration parameters, configure resources for the TSC data stream and continuously support service continuity.

Abstract: A method, apparatus and computer program product are provided in accordance with example embodiments in order to provide methods, apparatuses, and/or systems that reduce and/or eliminate network inefficiencies caused by the persistence of user-equipment-specific associations with network interfaces and elements, including but not limited to user-equipment-specific associations on at least N2. In some example implementations, an AMF may assign a temporary ID containing particularized identification information to a UE in a manner that allows for selection by a (R)AN of a AMF and that enables an AMF to process an N1/N2 transaction, such as may occur when a UE enters an idle mode and/or transitions from an idle mode to a connected mode.

Abstract: In some example embodiments, there is provided a method. The method may include generating, by a network node, a message including an indication of whether a bearer is at least one of a default bearer or a dedicated bearer; and sending, by the network node, the generated message, wherein the generated message is sent to a base station to enable the base station to control assignment of the bearer to a macrocell when the indication represents that the bearer is a default bearer. Related systems, methods, and articles of manufacture are also described.

Abstract: A method, apparatus, and computer program product provide for generating and providing a signaling indicator to manage quality of service notifications in a network. In the context of a method, the method receives a signaling indicator from a user device. The signaling indicator includes data associated with one or more preferences of the user device. The method further receives a quality of service notification associated with the user device. The method also determines, based on the signaling indicator, whether to provide the quality of service notification to the user device.

Abstract: Systems, methods, apparatuses, and computer program products for access traffic steering, switching, and splitting (ATSSS) with branching point (BP) on the path are provided. The method may include determining that an existing user plane function is sub-optimal in terms of routing and latency incurred with respect to traffic for a given packet data unit session of a user equipment. The method may also include establishing, based on the determination, a new user plane function for the packet data unit session. The method may further include establishing a branching point user plane function that interfaces with the existing user plane function, the new user plane function, and a plurality of network access types. In addition, the method may include updating the user equipment by providing the user equipment with relevant multi-access traffic steering rules.

Abstract: A method, apparatus and computer program product are provided herein to provide service continuity between a Stand-alone Non-Public Network (SNPN) and a Public Land Mobile Network (PLMN). For example, a method is provided that comprises after determining that the user equipment (UE) with the first protocol data unit (PDU) session established in the first SNPN is or will be leaving the coverage area of the first SNPN, causing a request message to be transmitted to the UE, wherein the request message comprises a request to initiate a second PDU session establishment procedure towards a PLMN. The method also includes causing the UE to establish the second PDU session with an internet protocol anchor function of a user plane function in the PLMN via the first SNPN radio access network (RAN) or via the PLMN RAN, wherein the second PDU session is established prior to release of the first PDU session.

Abstract: A plurality of interworking functions, which provide interworking between a communication network acting as access network and another communication network, is associated with a plurality of network slices or non-public networks hosted by the other communication network. A user equipment performs connection (S301) to a communication network acting as access network, and selects (S303) an interworking function of the plurality of interworking functions based on information on a network slice or non-public network hosted by the other communication network, wherein the user equipment is associated with the network slice or non-public network.
