1. A method for use in a packet server, the method comprising the steps of:

  • negotiating compression of a GTP/UDP/IP header of a General Packet Radio Service based Tunneling Protocol (GTP) with a GTP peer, the GTP/UDP/IP header comprising GTP, User Datagram Protocol (UDP), and Internet Protocol (IP) header information including initially transmitting the GTP/UDP/IP header to the GTP peer; and

    subsequently compressing the GTP/UDP/IP header before transmitting the packets;

    wherein the compressed GTP/UDP/IP header comprises at least, an extension bit field, which indicates whether an extension field is present or not, a tunnel identifier present field, which indicates whether a tunnel identifier field is present or not.
