Abstract
A decompressor, a compressor and methods in an Internet Protocol (IP) network for reporting cause of missing packets. A cause of unsuccessful reception or sending of a compressed packet addressed is reported to a compressor/decompressor node. The compressor/decompressor node decides or predicts if a decompression context associated with the decompressor is invalidated by analyzing the cause of the unsuccessful reception and, optionally, analyzing a re-initialization agreement between the compressor and the decompressor. In an optional embodiment of the present invention, the compressor/decompressor node use the decision or prediction to exchange information to reinitialize the decompression context associated with the decompressor. In a preferable embodiment of the present invention, the detection of the unsuccessful sending or reception is performed at a Medium Access (MAC) layer associated with the compressor/decompressor node.
