    • 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.
    • 发送端(头压缩结束)和接收端(头部解压缩结束)共享预先准备的相同的时间戳计算信息。 在发送端,在当前时间戳计算信息不能压缩要进行头压缩的当前分组的时间戳的情况下,参照先前发送的覆盖时间戳计算信息的历史记录来确定是否发送 携带时间戳而不更新当前时间戳计算信息的分组报头,或者通过更新当前时间戳计算信息来携带时间戳的分组报头。
