Abstract: There are provided measures for enabling/realizing external steering of access traffic multipath communication in a mobile communication system, e.g. an external access traffic multipath communication steering function. Some such measures include that a session management function element or instance in a mobile communication system initiates control of establishment of at least one user plane session for access traffic multipath communication, obtains communication information of an external steering function element or instance to be used for steering access traffic multipath communication in the at least one user plane session, creates access traffic multipath communication rules, forwarding action rules and multi access rules for access traffic multipath communication in the at least one user plane session, and provides the access traffic multipath communication rules and the communication information of the external steering function element or instance to the communication function element or instance.

Abstract: There is provided a method for an apparatus for a network function, the apparatus for the network function, and a computer program for the apparatus, that causes the apparatus to: receive an indication that a first user equipment and/or a first user plane function configured to transmit first user traffic is associated with a first replication handling function, the first replication handling function being configurable to coordinate at least one replication-based redundancy mechanism performed on at least part of said first user traffic; determine a first set of replication rules for use by the first replication handling function determining when the at least one replication-based redundancy mechanism is performed on at least part of said first user traffic; and cause the first set of replication rules to be provided to the first replication handling function.

Abstract: Systems, methods, apparatuses, and computer program products for access traffic steering, switching, and splitting (ATSSS) with branching point (BP) on the path are provided. The method may include determining that an existing user plane function is sub-optimal in terms of routing and latency incurred with respect to traffic for a given packet data unit session of a user equipment. The method may also include establishing, based on the determination, a new user plane function for the packet data unit session. The method may further include establishing a branching point user plane function that interfaces with the existing user plane function, the new user plane function, and a plurality of network access types. In addition, the method may include updating the user equipment by providing the user equipment with relevant multi-access traffic steering rules.

Abstract: Systems, methods, apparatuses, and computer program products for access traffic steering, switching, and splitting (ATSSS) with branching point (BP) or uplink classifier (ULCL) on the path. The method may include, setting up, in response to a request, a first user plane function with multi-access traffic steering functionality. The method may also include requesting a user equipment to establish a new multi-access packet data unit session to a same data network name and slice as an old multi-access packet data unit session, or request the user equipment to release the old multi-access packet data unit session with a second user plane function and to initiate a multi-access packet data unit session re-establishment. The method may further include sending, to the user equipment, multi-access rules for the new multi-access packet data unit session, a new internet protocol address, and new multipath transmission control protocol proxy information.

Abstract: There is provided an apparatus, method and computer program fora network function, that causes the apparatus to signal, to a replication handling function, a set of replication criteria defining, for one or more session associated with a first user traffic and a second user traffic, when at least one of the first and second user traffic will be transmitted using a replication-based redundancy mechanism, wherein each of the first and second user traffic are associated with a respective quality of service requirement for transmission.
