Abstract�� To solve the data compression problem and improve the transmission efficiency in the ATN(aeronautical telecommunication network) mobile communication network, the data packets headers compression algorithm of CLNP(connectionless network layer protocol) is discussed in detail. The relationships of transmission efficiency, compression rate and packet length are given by analyzing compression procedure and capability. Combining ESIS(end system to intermediate system) protocol, an improved header compression algorithm of CLNP data packet is presented in the IDRP(inter-domain routing protocol) routing algorithm. The impression efficiency of packets headers is analyzed and the correlation between impression efficiency and packet length is given. The simulation results showed that the new algorithm could promote the compression efficiency of data packets and transmission efficiency of the network.
Keywords�� mobile communication   air line networks   header compression   connectionless network layer protocol   aeronautical telecommunication network
