Abstract
A method is described for associating a data packet (DP) with a packet bearer (PB) in a user equipment (UE1) of a communication network. The data packet is sent in a data flow from an application function of the user equipment, the packet bearer (PB) is established with the user equipment to transmit the data packet (DP) over the communication network towards a further entity, and the user equipment is adapted to establish different packet bearers. The method comprises the steps of identifying the flow with the data packet in a control entity of the communication network, determining the packet bearer for association with said flow from the different packet bearers in a policy function of the control entity, determining a routing level identification of the further entity, instructing the user equipment to install a packet filter based on the routing level identification, wherein the packet filter associates data packets comprising the routing level identification of the further entity with the determined packet bearer, providing the routing level identification to the application function, including the routing level identification into the data packet, and forwarding the data pac…
