Abstract: Network nodes including relays and access nodes are configured to transport data packets by identifying the type of data packet and correspondingly compressing a header portion of the data packet. Operations described herein may be implemented in a network that is capable of transporting voice over LTE (VoLTE) data packets using the GPRS tunneling protocol (GTP). A unique value is marked to an IP header of the voice data packet, and the GTP headers may be mapped to a unique bearer that is different from a standard voice bearer used in the network. The compression uses a robust header compression (RoHC), which includes compressing a RTP header portion along with a GTP header portion using existing or new compression profiles.
