Abstract: A technique comprising: sending to a proxy function from a client function a first service request for which the client function delegates to the proxy function discovery, via a network repository function, of a service producer for the first service request; receiving at the client function in reply to the service request a service response, wherein the service response includes an authorisation token indicating a token scope; and in response to a determination that the indicated token scope at least partly matches a requested scope for a second service request regardless of whether the token scope fully matches the requested scope, including the authorisation token in the second service request.

Abstract: Systems, methods, apparatuses, and computer program products for restoration of multicast/broadcast service upon multicast/broadcast user plane function failure without restart are provided. For example, a method may include detecting non-functionality of a first multicast/broadcast user plane function that was supporting a packet forwarding control protocol session context for a multicast/broadcast session. The method may also include reselecting a second multicast/broadcast user plane function. The method may further include recreating a packet forwarding control protocol session context in the second multicast/broadcast user plane function for said multicast/broadcast session. The method may additionally include receiving new addressing information for the delivery of said multicast/broadcast session data from said second multicast/broadcast user plane function. The method may also include updating a network element with the new addressing information.

Abstract: Systems, methods, apparatuses, and computer program products for broadcast service restoration for multicast/broadcast service upon radio access node failure or restart are provided. For example, a method may include storing a last multicast/broadcast service session information received from a multicast/broadcast session management function corresponding to a multicast/broadcast service session. The method may also include detecting that a radio access node associated with the multicast/broadcast service session has restarted or is unreachable. The method may further include taking a further action to adjust the delivery of the multicast/broadcast service session based on the detection.

Abstract: A technique comprising: receiving, at a session management function, information by which is identifiable a plurality of multicast service areas for a multicast session managed by the session management function; and directing towards a radio access network node an indication of the plurality of multicast service areas; wherein the plurality of multicast service areas is a subset of the set of multicast service areas for the multicast session.

Abstract: A method comprising: generating an indication comprising a scope parameter and at least one of: a network function service instance identifier, a network function service set identifier, a network function instance identifier, a network function set identifier, and a service name, wherein the scope parameter is configured to indicate at least one scenario to which an associated binding relates; and sending (404) the indication from a network function service consumer to a network function service producer.

Abstract: Systems, methods, apparatuses, and computer program products for multicast-broadcast service (MBS) deactivation and/or activation are provided. One method may include receiving, at a multicast-broadcast session management entity, a multicast-broadcast service (MBS) session setup message, from at least one management entity, comprising at least one of an identifier of at least one network node requesting setup of the multicast-broadcast service (MBS) session and an identifier of the at least one management entity. The method may also include storing, at the multicast-broadcast management entity, at least one of the identifier of the at least one network node, the identifier of the at least one management entity, or an identifier of a region of the at least one management entity.
