VoIP header compression method suitable for small local area network

Abstract

The embodiment of the invention discloses a VoIP (Voice over Internet Protocol) header compression method suitable for a small local area network. The method comprises the following steps: statically compressing a data packet in a header at a source node; judging whether the statically compressed headers need aggregation compression or not according to the judgment basis, and if not, sending the statically compressed headers to the target node; and performing aggregation compression on the masthead after static compression, and sending the masthead to a target node after compression is completed. The method provides possibility for VoIP data transmission in a small local area network by using a wireless narrowband in a complex battlefield environment.

Description

technical field [0001] The present invention relates to header compression technology. More specifically, it relates to a VoIP header compression method suitable for small local area networks. Background technique [0002] The principle of VoIP is to use digital processing to compress and package analog voice signals, send the voice packets to the receiving end through the IP network, and perform digital processing here, and finally realize the end-to-end two-way communication model. Compared with traditional circuit-switched voice communication, this network-based voice communication method has the characteristics of easy integration, low cost, strong anti-interference, and good confidentiality, and can adapt to complex communication environments. [0003] At the same time, in a complex battlefield environment, the voice bandwidth of the wireless channel of the small LAN is generally narrow. If the header cannot be effectively compressed, it will be far less than the bandw...

Problems solved by technology

[0003] At the same time, in a complex battlefield environment, the voice bandwidth of the wireless channel of the small LAN is generally narrow. If the header cannot be effectively compressed, it will be far less than the bandwidth required for VoIP transmission.

Therefore, even though VoIP has many advantages, in the past most of the voice communication between small LANs in complex battlefield environments was realized through circuit switching, and the header compression became the bottleneck restricting the military application of VoIP
