A data communication system employs a method (400) for transmitting packetized data (100) using a combination of well known transmission techniques, such as TCP/IP and a novel compression process. A message type identifier (300) for the packet to be transmitted is first identified, which identifier comprises a packet type identifier (113) and a protocol identifier (114). The packet type identifier (113) distinguishes between control information and user information in the data packet. The packet is then selectively encoded (407, 411) using either a first or a second header compression technique, depending on the packet type identifier (113) and the protocol identifier (114). In this manner, an improved packet transmission scheme is envisaged, which gives a reliable solution for data transmission in a noisy RF environment and/or a bandwidth-limited environment. The method (400) for transmitting packetized data (100) further anticipates a third header compression technique (417) for use when the packet to be transmitted includes a UDP message.
