Marking an uplink data packet

A method comprising:

• establishing a bearer for a terminal device of a cellular communication system;
• receiving, from the terminal device over the bearer, an uplink data packet comprising an information element indicating a service associated with the uplink data packet;
• sending a query comprising the information element to a networking controller;
• receiving, from the networking controller as a response to the query, routing information for the uplink data packet, wherein the routing information comprises an information element indicating a forwarding policy to the uplink data packet;
• marking the uplink data packet with the routing information and forwarding the uplink data packet to a transport network;
• and
• selecting transmission parameters to the uplink data packet based on the routing information.
