Abstract: Embodiments of the present disclosure relate to methods, apparatuses and computer program products for enforcing a rule related to traffic routing. A method implemented at a terminal device comprises receiving a rule related to traffic routing for traffic and enforcement information for the rule; and controlling enforcement of the rule based on the enforcement information. The enforcement information indicates whether a modification to a PDU session associated with the traffic due to the enforcement of the rule is allowed.

Abstract: This invention relates to a method for Core Network (CN) controlled traffic transmission in a dual/multiple-connectivity system. The method comprises the following steps: receiving a request containing information about a status of dual/multiple connectivity from the radio access network node; determining and providing a policy on a usage of dual/multiple connectivity to the radio access network node. This invention also relates to a system of Core Network (CN) controlled traffic transmission for a dual/multiple-connectivity, an apparatus for Core Network (CN) controlled traffic transmission in a dual/multiple-connectivity system and a non-transitory computer-readable medium with executable instructions for executing the method.
