In a mobile telecommunications network including a mobile User Equipment (UE) and a Packet Data Network (PDN) Gateway (PGW), a method is provided for controlling data packet header overhead for real time data packet traffic between the UE and the PGW. The method includes: modifying one or more data packets having an Internet Protocol (IP) header and a User Datagram Protocol (UDP) header to remove at least a portion of at least one of said IP and UDP headers prior to transporting said modified data packet between the UE and PGW; and reconstructing the removed header portions upon receipt of the modified data packet at one of the UE or PGW.
