11. A method, comprising:

associating, at a fixed access node connected to the transport network underlay of a mobile packet network, a service port of a fixed network termination with a user plane packet processing function,

sending, by the fixed access node, a service frame received from said service port to the user plane packet processing function of the fixed access node,

determining, by the fixed access node, at least one destination tunnel end point out of a plurality of destination tunnel end points according to forwarding rules, and

sending, by the fixed access node, the service frame to the selected destination tunnel end point by encapsulating the service frame into a frame of a transport network underlay which is addressed to the destination tunnel end point, wherein

the destination tunnel end point is associated with a physical or virtual interface on a radio modem of a user equipment in a mobile packet network or on a mobile network gateway.

12. An apparatus for use in a base station of a mobile packet network, comprising:

at least one processor; and

at least one memory for storing instructions to be executed by the processor, wherein

the at least one memory and the instructions are configured to, with the at least one processor, cause the apparatus at least to perform

associating, at the base station of a mobile packet network, a service port of a radio modem of user equipment in the mobile packet network with a user plane packet processing function,

sending, by the base station, a service frame received from said service port to the user plane packet processing function of the base station,

determining, by the base station, at least one destination tunnel end point out of a plurality of destination tunnel end points according to forwarding rules, and

sending, by the base station, the service frame to the selected destination tunnel end point by encapsulating the service frame into a frame of a transport network underlay which is addressed to the destination tunnel end point, wherein

the destination tunnel end point is associated with a physical or virtual interface on another radio modem of another user equipment in a mobile packet network or on a fixed network termination.

13. The apparatus according to claim 12 , wherein

the destination tunnel end point is determined by the base station

by selecting at least one destination service port out of a plurality of destination service ports according to the forwarding rules, and

by associating the at least one selected destination service port with a corresponding destination tunnel end point.

14. The apparatus according to claim 13 , wherein the at least one memory and the instructions are further configured to, with the at least one processor, cause the apparatus at least to perform:

receiving, at the base station, the association of the at least one selected destination service port with the corresponding destination tunnel end point from a mobility control function.

15. The apparatus according to claim 14 , wherein

the association is received from the mobility control function via a data bus, the mobility control function being capable of distributing or updating the association via the data bus between multiple network elements.
