Abstract

In a packet-base communications system where each packet includes a header and an associated data portion, message packets are communicated between devices on first and second networks through a gateway. The first network uses a standard internetwork protocol (IP). Predetermined fields in the standard (IP) header of each message packet are eliminated to obtain a modified header before transmitting message packets over the second network to the second device. Conversely, one or more predetermined fields are added to the modified header of each packet in another message from the second device to the first device to convert that modified header into a corresponding standard IP header before transmission over the first network. In a specific embodiment, the present invention permits internetwork communications between computers in a radio frequency communications network and computers connected to a wireline network compatible with conventional TCP/IP protocols. Unnecessary IP header bits are removed before packets are transmitted over the radio network to conserve RF channel bandwidth. Knowledge of information already present on the data link layer of the RF channel communications protocol is used to omit unnecessary or redundant fields in the standard IP header of the network layer. Enough information is preserved in the reduced IP network header so that the standard IP header may be reassembled/reconstructed.
