Abstract: A method includes connecting, by a terminal device, in a protocol data unit session establishment procedure, to at least one master node and at least one network node that provides a proxy for at least one connection of the terminal device, and establishing a master multipath transmission control protocol sub-flow. The method includes receiving, at a multipath transmission control layer, a notification that includes at least one multipath transmission control segment with an add address option that advertises an internet protocol interface address of at least one of the proxy and the at least one network node, and establishing a secondary multipath transmission control protocol sub-flow to the internet protocol interface address in response to receiving the notification.

One method may include detecting, by a network entity, that two or more flows of packets are related. The method may then include informing lower layer(s) that the packets are related along with their QoS constraints, and directing the lower layer(s) to ensure that latency, availability and/or reliability requirements of the packets are fulfilled.

Abstract: According to certain embodiments, a method and apparatus may include performing, by a first network entity, at least one benchmarking procedure of at least one network hop delay per at least one transmit resource towards at least one peer network node identified by at least one internet protocol destination address. The method and apparatus may further include deriving, by the first network entity, a second table, by, for each peer node associated with an internet protocol destination address, determining at least one existing configured mapping of at least one network instance into a transport resource Ti per internet protocol destination address. The method and apparatus may further include updating, by the first network entity, the first table and the second table for each internet protocol destination address and transmitting the updated second table to the second network entity.

Abstract: Various communication systems may implement network management tools to help manage registration requests from a user equipment. For example, network functions in a communication system with a shared data layer may be used to manage requests from the user equipment. A method may include transmitting a request from a user equipment to a network function. The method may also include receiving at the user equipment a temporary identification from the network function The temporary identification comprises an identifier that helps locate a shared data layer function that stores context information for the user equipment. In addition, the method may include transmitting from the user equipment a subsequent request comprising the temporary identification to another network function or the network function.

Abstract: A method, apparatus, and computer program product provide for providing quality of service management during immersive content consumption. In the context of a method, the method includes receiving a first request comprising a positioning error set. The method also includes determining, based at least on the first request, an enhanced quality of service (QoS) indicator representing a QoS for a client device associated with the positioning error set. The method also includes causing transmission of a first response comprising configuration data related to a QoS flow for the client device, the configuration data being based at least on the enhanced QoS indicator.

Abstract: Described are apparatuses, methods, and computer program products for enabling splitting, switching, and steering of access traffic in a system, e.g., a fifth-generation (5G) system. Access and mobility management functions (AMF) of the 5G system forward one or more of the registration requests to unified data management (UDM) functions of the PLMNs. UDM function determines whether evolved packet system (EPS) interworking (IWK) is allowed for respective registration requests based on subscription, deployment, system capabilities, a radio access technology (RAT) of an access path between the UE and the 5G system, etc. UE can include an indication that EPS IWK is requested and/or required in a registration request.

Abstract: Methods and apparatuses for enhancement of quality of service flows, for extended reality services or other services are proposed. For example, a method can include receiving a plurality of quality of service parameters for first packet-based communication. The quality of service parameters can include a packet delay budget for the first packet-based communication having a first end time. The plurality of quality of service parameters can further include a packet validity time for the first packet-based communication having a second end time equal to or later than the first end time. The packet validity time can be applicable to the first packet-based communication on a protocol data unit session basis, a quality of service flow basis, a set of protocol data units basis, or a packet basis. The method can also include transmitting the packet of the first packet-based communication to a further communication device.
