Abstract
A transmission end (header compression end) and a reception end (header decompression end) share the same timestamp calculation information which is previously prepared. At the transmission end, in the case that the timestamp of the current packet to be subjected to header compression cannot be compressed with the current timestamp calculation information, the history record which covers timestamp calculation information previously transmitted is referred to for determining whether to transmit a packet header carrying the timestamp without updating the current timestamp calculation information, or a packet header carrying the timestamp by updating the current timestamp calculation information.
