Transport of data flows over cellular networks

A method performed by a core network node for a wireless communications network for transport of data packets associated with a data stream in an external Ethernet data network, the method comprising:

• obtaining configuration information for the data stream in the external Ethernet data network, the configuration information indicating respective values for one or more fields within a header of data packets associated with the data stream, wherein the respective values for the one or more fields are to remain static;
• receiving a data packet associated with the data stream from a wireless device;
• adding the one or more fields to the data packet to generate a decompressed data packet;
• and
• initiating transmission of the decompressed data packet over the external Ethernet data network.
