Abstract: Techniques for relayed connection between nodes are provided. For example, a method for relayed connection between nodes comprises sending, from a source node to a relay node, a communication request message for establishing a connection to a target node via the relay node; and receiving, at the source node from the relay node, a communication reject message indicating a rejection to establish the connection by the target node.

Abstract: Systems, methods, apparatuses, and computer program products for roaming of multicast MBS services. One method may include attaching, by a user equipment, to a visited public land mobile network as inbound roamer. The user equipment then receives a service announcement comprising at least one of a multicast service session allowed to be accessed by inbound roamers indication or multicast service class. The user equipment determines whether the user equipment is allowed to access a multicast session or multicast service class in the visited public land mobile network. The user equipment transmits, in response to determining that the user equipment is allowed to access, a request to join a multicast session comprising an identifier of the multicast session and/or a multicast service class. The user equipment receives an indication of an acceptance or rejection of the request to join the multicast session.

Abstract: There is provided an apparatus comprising: means for storing at least one flag in a first state at a first time, wherein the at least one flag is associated with at least one user equipment and the first state indicates that no policy association is required for the at least one user equipment; means for receiving, at a second time which is after the first time, a request from a network exposure function indicating that the at least one flag should be updated to a second state, wherein the second state indicates that a policy association is required for the at least one user equipment, wherein a purpose of the policy association is to satisfy service requirements of a service which has been or will be provisioned at the at least one user equipment; and means for, in response to receiving the request, updating the flag to the second state.

Abstract: Systems, methods, apparatuses, and computer program products for emergency sessions, such as emergency calls, using a relay provided by proximity services are provided. For example, a method may include indicating, in a relay discovery procedure, a capability of a relay user equipment to support an emergency call. The method can alternatively or in addition include receiving, in the relay discovery procedure, an indication of a need of a remote user equipment to conduct an emergency call.

Abstract: A H-SMF receives, from a V-SMF in a VPLMN, a join request originating from a UE roaming in the VPLMN to join a multicast multicast and broadcast services (MBS) session, and determines whether the UE is authorized to join the multicast MBS session based upon a local configuration in a home public land mobile network, information received from an application function during establishment of the multicast MBS session, and/or user subscription data received from a user data manager. The H-SMF at least one of: transmits to the V-SMF, if the UE is authorized, an acceptance response configured to establish at least one unicast QoS flow corresponding to multicast QoS flow information received from a H-MB-SMF, or, if the UE is not authorized, a rejection response comprising error cause information indicating that the UE is not authorized to join while roaming.

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.
