Abstract: Methods and apparatuses for edge services are disclosed. A network function entity receives from an application function entity a request relating to a data communication session, and can then determine, in response to the request, information of at least one local network exposure function entity for the application function entity. The application function entity is provided with the information of the at least one local network exposure function entity. The information can be used in connecting with a local network exposure function entity. The local network exposure function entity can then be used for the data communication session.

Abstract: Systems, methods, apparatuses, and computer program products for distributing multicast packets in individual protocol data unit (PDU) sessions are provided. One method may include receiving, at a user plane node, a request from a session management node, to receive packets for a multicast session and/or to send packets from the multicast session within a protocol data unit (PDU) session. The method may also include determining whether the user plane node was already configured to receive incoming packets for the multicast session, and informing the session management node as to whether the user plane node was already configured to receive the incoming packets for the multicast session.

Abstract: Techniques for enforcing packet detection rules within communication systems are provided. A network entity may configure a user plane function to detect whether a domain name system request sent by a user equipment satisfies one or more packet detection rules. The network entity may receive, from a user plane function, a report that a domain name system request sent by the user equipment has been detected as non-compliant with instructions sent to the user equipment. The network entity may cause one or more corrective actions relating to traffic offloading.

Abstract: A method, apparatus and computer program product are provided herein to provide service continuity between a Stand-alone Non-Public Network (SNPN) and a Public Land Mobile Network (PLMN). For example, a method is provided that comprises after determining that the user equipment (UE) with the first protocol data unit (PDU) session established in the first SNPN is or will be leaving the coverage area of the first SNPN, causing a request message to be transmitted to the UE, wherein the request message comprises a request to initiate a second PDU session establishment procedure towards a PLMN. The method also includes causing the UE to establish the second PDU session with an internet protocol anchor function of a user plane function in the PLMN via the first SNPN radio access network (RAN) or via the PLMN RAN, wherein the second PDU session is established prior to release of the first PDU session.

Abstract: There are provided measures for local user plane function control. Such measures exemplarily comprise obtaining access network related information, receiving, from a session management function entity, at least one pre-rule, generating, based on said at least one pre-rule and said access network related information, a first rule of at least one rule related to local traffic offloading, assigning said first rule to a first user plane function entity of at least one user plane function entity under control of said intermediate session management function entity, and transmitting said first rule to said first user plane function entity.

Abstract: There is disclosed an apparatus (408). The apparatus comprises means for performing: receiving user plane traffic at the apparatus (408), the user plane traffic intended for a group local area network communication; and determining a target destination address for the user plane traffic; and autonomously handling the received user plane traffic at the apparatus (408) in dependence on the target destination address; and wherein the autonomously handling the received user plane traffic by the apparatus comprises determining whether the destination address is recognised by the apparatus (408); and forwarding the user plane traffic towards all interfaces (424) tagged as network interfaces associated with the group communication, when the destination address is determined to be not recognised by the apparatus (408).

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.
