Abstract:
1. An adaptive telecommunications packet transmission system comprising: a compression engine configured to compress a header of at least one uncompressed packet and send at least one compressed packet corresponding to the at least one uncompressed packet across at least one communication channel coupled to the compression engine; a decompression engine coupled to the at least one communication channel configured to receive from the at least one communication channel the at least one compressed packet and to decompress the header of the at least one compressed packet, the decompression engine configured to report at least one error if the header of the at least one compressed packet cannot be decompressed and to report at least one success if the header of the at least one compressed packet can be decompressed; and a refresh rate calculator coupled to the decompression engine configured to receive the at least one error and the at least one success from the decompression engine and calculate an adaptive refresh rate as a ratio of a number of compressed packets to a number of uncompressed packets sent by the compression engine in response to the at least one error or the at least one success, the refresh rate calculator configured to send at least one uncompressed packet containing the adaptive refresh rate across the at least one communication channel to the compression engine; wherein the compression engine is configured to transmit at least one uncompressed packet across the communication channel according to the adaptive refresh rate received from the refresh rate calculator; and wherein in a first time interval, the number of compressed packets sent across the at least one communication channel is different than the number of compressed packets in a second time interval in response to a change in the adaptive refresh rate.
