Abstract
A method and apparatus for replacing a transport layer header error detection code and a header compression algorithm error detection code with a one error detection code. The replacement error detection code covers both the transport layer header and the transport layer payload. Such an arrangement reduces the amount of as-is or uncompressed information transmitted, thereby reducing the required bandwidth. The replacement error detection code is subsequently used to verify the correctness of both the reconstructed header and the payload.
