Problems solved by technology

[0024] However, updates to the compression / decompression rules again require exchanging additional data, reducing the bandwidth available for useful data
[0025] Furthermore, this additional data exchange can take a long time because of the limited bandwidth of LPWAN networks, which limits the adaptability of the compression / decompression rules to the actual data flow on the communication link
Also, the time spent exchanging additional data may significantly affect the real-time exchange of useful data between devices implementing the rules in question

Embodiment Construction

[0085] In all the drawings of this document, the same elements and steps have been referenced with the same reference numerals.

[0086] The general principles of the described technology include a method for learning a compression / decompression context comprising at least one compression / decompression rule for the first data stream sent by the channel. In this method, at least one of a compressor device, a decompressor device and a third device (different from the compressor device and the decompressor device) according to the to learn the compression / decompression rules in question from the second uncompressed data stream sent in between.

[0087] Thus, the bandwidth of the first communication link remains dedicated to the exchange of useful data.

[0088] will now refer to figure 1 A system comprising a compressor device 100a and a decompressor device 100b according to one embodiment of the described technology is described.

[0089] In this embodiment, the compressor d...

Abstract

The invention concerns a method for learning from a compression / decompression context comprising at least one compression / decompression rule intended to be used by a compression device and a decompression device, to respectively compress and decompress a first flow of data transmitted via a first communication link. According to such a method, at least one device, among the compression device, thedecompression device and a third device, carries out the following steps: analysis (E200) of at least one second flow of non-compressed data, transmitted between the compression device and the decompression device via at least one second communication link; and learning (E210) of the at least one compression / decompression rule, depending on the analysis.

Description

technical field [0001] The present invention relates to the field of compression and decompression of data exchanged via communication links, in particular but not limited to header data. [0002] More precisely, the present invention relates to a method that allows learning to exchange compressed data via such a link (one is a compressor and the other is a decompressor) while minimizing the reduction in the useful bandwidth of the link in question. method for the compression / decompression context (including at least one compression / decompression rule) to use. [0003] The present invention has many applications, especially but not exclusively, in the field of the Internet of Things (IoT), which is data dedicated to these things which usually have narrow bandwidth in order to limit the power consumption of things in mobile applications switched network. [0004] Examples of these networks are those based on SemTech LoRa, SIGFOX, NB-IoT, EC-GSM, Cat-M1, Weightless, Ingenu / RPM...
