Layer two compression/decompression in a cellular communications network

摘要

The device (5) has an analyzing unit (7) to analyze header of a transcoder/rate adaptor unit frame or signaling contained in successively received input frames to determine type of the input frame. A compression unit (8) periodically generates compressed frames that are subdivided into a section having critical data compressed in a synchronous manner, and a section having non-critical data compressed in asynchronous manner. An independent claim is also included for a compressor/decompressor comprising a data compression device and a data decompression device.
