Abstract: Systems, methods, apparatuses, and computer program products for access traffic steering, switching, and splitting (ATSSS) with branching point (BP) or uplink classifier (ULCL) on the path. The method may include, setting up, in response to a request, a first user plane function with multi-access traffic steering functionality. The method may also include requesting a user equipment to establish a new multi-access packet data unit session to a same data network name and slice as an old multi-access packet data unit session, or request the user equipment to release the old multi-access packet data unit session with a second user plane function and to initiate a multi-access packet data unit session re-establishment. The method may further include sending, to the user equipment, multi-access rules for the new multi-access packet data unit session, a new internet protocol address, and new multipath transmission control protocol proxy information.

Abstract: Methods, computer program products, and apparatuses are provided for enabling a user equipment (UE) to connect to the wireless access network that support non-seamless wireless local area network (WLAN) offload (NSWO), such as using the UE's fifth generation (5G) credentials. An apparatus may include a processor and a memory storing computer program code configured to cause the apparatus to request, by the UE, a wireless connection to a network entity; receive, by the UE, from the network entity, an identity request; and in response to the identity request, cause transmission, by the UE, an identity response including a UE identifier to the network entity such that the UE is configured to establish a security context with the network entity upon successful authentication using the UE identifier.

Abstract: This specification describes apparatus comprising means for sending, from a first network function service consumer instance to an authorisation server, a request for an access token for use in accessing a service provided by a network function service producer, wherein the request includes an identifier of a set of network function service consumer instances of which the first network function service consumer instance is a member; receiving, at the first network function service consumer instance from the authorisation server, an access token for use in accessing the service provided by the network function service producer, wherein the access token includes the identifier of the set of network function service consumer instances of which the first network function service consumer instance is a member; and sending, from the first network function service consumer instance to the network function service producer, a request to access the service provided by the network function service producer, wherein the request to access the service includes the access token.

Abstract: Improved techniques for secure access control in communication systems are provided. In one example, in accordance with an authorization server function, a method comprises receiving a request from a service consumer in a communication system for access to a service type and one or more resources associated with the service type. The method determines whether the service consumer is authorized to access the service type and the one or more resources associated with the service type. The method generates an access token that identifies one or more service producers for the service type and the one or more resources associated with the service type that the service consumer is authorized to access, and sends the access token to the service consumer. The service consumer can then use the access token to access the one or more services and one or more resources. In addition to such resource level access authorization, target network function group access authorization can be performed.

Abstract: A control plane function of a core network of a communication network system derives a parameter relating to transport resources for a user plane from an identification relating to logical network resources of a session, and provides the parameter to a user plane function of the core network and to a control plane control unit of an access network. The control plane control unit provides information derived from the parameter to a user plane control unit of the access network, and wherein the transport resources relate to a logical transport network to use to carry the user plane of the session. Based on the received information, the user plane control unit derives the transport resources to be used for the session over the user plane, and exchanges user plane traffic for the session over the derived transport resources.

Abstract: User equipment appends a header to a non-access stratum (NAS) message to form an encapsulated NAS message. The header is formed according to a wireline access network protocol. The user equipment transmits the encapsulated NAS message over a wireline connection between the user equipment and an interworking function of a core network. The interworking function receives the encapsulated NAS message over the wired connection and forwards the NAS message to a core network entity selected based on addressing information included in the header. A point-to-point control plane session can be established between the user equipment and the interworking function in response to a session request transmitted by the user equipment. The point-to-point control plane session can be used to convey encapsulated NAS messages, which can be used to request establishment of an NAS session for a user plane connection to the core network.
