Layer 2 compression/decompression for mixed synchronous/asynchronous transmission of data frames within a communication network
First Claim
1. A compression device for compressing data contained in input frames to be compressed constituted of stream frames defining portions of transmission rate adaptation unit (TRAU) and signaling frames that have to be transmitted within a communication network and each of which comprising at least a header containing control data representative at least of one of a type of the stream frame and payload data, certain types containing at least one of critical and non-critical data, the compression device comprising:
- analysis module which analyzes each TRAU or signaling frame header contained in successively received input frames and determines the type of a respective input frame; and
compression module which generates periodically compressed frames, wherein each frame is divided into a first section of a first size, which corresponds to a critical data size, and a second section of a second size, different from the first size,said critical data is compressed synchronously into the first section,said non-critical data is compressed asynchronously into the second section after the critical data of the critical data size is compressed into the first section, andthe compressed frame having the first section and second section is transmitted within the communication network.

Abstract
A device is disclosed for compressing data contained in input frames to be compressed constituted of stream frames defining portions of TRAU and signaling frames that have to be transmitted within a communication network and each of which is constituted of at least a header containing control data representative at least of the type of stream frame and where applicable payload data, certain types containing critical and/or non-critical data. The device analyzes each TRAU or signaling frame header contained in successively received input frames in order to determine its type and generates periodically compressed frames to be transmitted that are divided into first and second sections of variable size. The first section contains critical data compressed synchronously and the second section contains non-critical data compressed asynchronously.

15. A compression device for compressing data of input frames, each comprising at least a header including control data indicative of a frame type, the compression device comprising:
-
analysis module which analyzes each frame header to determine a type of the frame, identifies data in the frame as being at least one of critical data or non-critical data, and determines a type of compression to be applied to the data of the input frames based on the frame type and data type; and compression module which splits a size of each frame into a first section of a first size, which corresponds to a critical data size and a second section of a second size, different from the first size, based on a size of the critical data to be compressed, compresses the critical data into the first section synchronously and the non-critical data into the second section asynchronously after the critical data of the critical data size is compressed into the first section, and transmits the compressed frame having the first section and second section within the communication network.
