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.
