Abstract: There is provided an apparatus comprising at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus to perform at least: receiving from at least one security edge protection proxy, SEPP, a registration message indicative of at least: at least one remote public land mobile network, PLMN, and/or at least one remote stand-alone non-public network, SNPN, the at least one SEPP is connected to; at least one agreed interface purpose per remote PLMN and/or remote SNPN the at least one SEPP is connected to, wherein the interface purpose is a purpose of intended usage of a connection over an inter-network interface; receiving a discovery request for a SEPP, which is configured to support connecting to a target PLMN or SNPN for interface purpose or interface purposes specified in the discovery request; selecting, among the at least one SEPP, at least one SEPP configured to support connecting to the target PLMN or target SNPN for the interface purpose or interface purposes specified in the discovery request; and transmitting, in response to the discovery request, information on the selected at least one SEPP.

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: There is provided a method, computer program, and an apparatus for a network function that causes the network function to: receive, from a service consumer, event subscription information comprising an intra-domain address and an inter-domain address for signalling event subscription notification information from a service producer to the service consumer; determine whether a first service producer is located in the same domain as the service consumer; select at least one of the inter-domain address and the intra-domain address to signal to the first service producer in dependence on said determining; and signal the selected at least one address to the first service producer.
