CN1866908A 一种在无分片特定环境中压缩IP－UDP报文头的方法 无效 - 驳回

一种在无分片特定环境中压缩IP－UDP报文头的方法
摘要：
本发明的在无分片特定环境中压缩IP－UDP报文头的方法主要包括：步骤S1：发送端向接收端发送全头报文；步骤S2：接收端在收到上述全头报文后，记录CID及报文头中固定域的值，生成报文流上下文；步骤S3：发送端再向接收端发送压缩头报文，其中该压缩头报文的报文头只带有CID字段；步骤S4：接收端在收到上述压缩头报文后，根据上述CID，查找与其对应的报文流上下文，然后根据该报文流上下文所记录的值来恢复IP－UDP报文的原始报文头。采用本发明所述的方法，通过压缩IP－UDP报文头中的全部字段，提高了链路传输效率，节省了链路的带宽。
摘要（英）：

The invention relates to a method for compressing the IP-UDP message head in non-split condition, which comprises: S1, the sending terminal sends complete message to the receiving terminal; S2, the receiving terminal receives said message and records CID and the value of fixed region of message head, to generate the context of message flow; S3, the sending terminal sends compressed-head message to the receiving terminal, while said message head only contains CID word; S4, the receiving terminal receives said compressed-head message, based on CID, to search for the context of relative message flow, and based on the value recorded by said context, to recover the original message head of IP-UDP message. The inventive method, via compressing the total word of IP-UDP message head, improves the chain transmission efficiency and save the wideband of chain circuit.
