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. ### Claim 2 (depends on 1) The apparatus according to claim 1, wherein the information element comprises quality of service information. ### Claim 3 (depends on 1) The apparatus according to claim 1, wherein the information element comprises a quality of service identifier. ### Claim 4 (depends on 3) The apparatus according to claim 3, wherein the information element comprises QCI/5QI of 3GPP specifications. ### Claim 5 (depends on 1) The apparatus according to claim 1, wherein the routing information comprises 802.1Q parameters. ### Claim 6 (depends on 1) The apparatus according to claim 1, wherein the routing information comprises a virtual local area network identifier. ### Claim 7 (depends on 1) The apparatus according to claim 1, wherein the routing information comprises header information; and the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to add the header information to the uplink data packet before forwarding. ### Claim 8 (depends on 1) The apparatus according to claim 1, wherein the routing information comprises a virtual identifier; and the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to select an output port for the uplink data packet based on the virtual identifier and output the uplink data packet to the output port. ### Claim 9 (depends on 1) The apparatus according to claim 1, wherein the networking controller is a software-defined network controller. ### Claim 10 (depends on 1) The apparatus according to claim 1, wherein the apparatus comprises a networking agent configured to interface with the networking controller. ### Claim 11 (depends on 1) The apparatus according to claim 1, wherein the service indicated by the information element comprises a virtual private network service. ### Claim 12 (depends on 1) The apparatus according to claim 1, wherein the apparatus is a base station. ### Claim 13 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. ### Claim 14 A non-transitory computer-readable medium storing computer program instructions, which when executed by a processor, cause an apparatus including the processor to perform at least the following: 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.
