Abstract: Systems, methods, apparatuses, and computer program products for roaming of multicast MBS services. One method may include receiving, by a user equipment attached to a public land mobile network as an inbound roamer, a service announcement for a broadcast session or service class indicating whether inbound roamers are allowed to access the broadcast service or service class; determining, based on the service announcement, whether the user equipment is allowed to access a broadcast session or service class in the public land mobile network; and in response to determining that the user equipment is allowed to access a broadcast session or service class in the public land mobile network, transmitting, by the user equipment, a multicast/broadcast service interest indication associated with the broadcast session or service class upon completion of a radio resource request.

Abstract: Systems, methods, apparatuses, and computer program products for creating implicit ad hoc groups of UE based upon specific criteria. One method may include forming, by a session management function, at least one ad-hoc group of user equipment based upon detecting user equipment matching at least one grouping criteria; and reporting, by the session management function, the forming of the at least one ad-hoc group to a network exposure function or an application function based upon at least one notification condition.

Abstract: Techniques for enhancing subscription authorization in a communications network are provided. For example, a method in a source network function service producer or an apparatus for a source network function service provider is disclosed. The method comprises: receiving a subscription request including access authorization information from a network function service consumer for a subscription to receive a notification upon occurrence of a specific event; verifying that the network function service consumer is authorized to create the subscription to the source network function service producer; storing subscription context and access authorization information granted for the subscription if the subscription request is authorized.

Abstract: Systems, methods, apparatuses, and computer program products for restoration of multicast/broadcast service upon multicast/broadcast failure with restart are provided. For example, a method may include detecting a restart of a multicast/broadcast user plane function that was supporting a packet forwarding control protocol session for a multicast/broadcast session. The method may also include re-creating a packet forwarding control protocol session for the multicast/broadcast session. The method may further include providing addressing information for the data delivery of the broadcast/multicast session to the multicast/broadcast user plane function and instructing the multicast/broadcast user plane function to use this addressing information for the broadcast/multicast session if possible.

Abstract: A method, apparatus and computer program product are provided herein to provide a Protocol Data Unit (PDU) session priority parameter. For example, a method is provided that comprises identifying a need in a user equipment (UE) for establishing a new protocol data unit PDU session. The method also includes evaluating whether to establish a new PDU session and determining whether to establish a new PDU session based on a PDU session priority parameter when a maximum number of PDU sessions the UE can establish in the network is reached.
