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.
Claims13
A method for replacing a transport layer error detection code in a header compression algorithm, the method comprising the steps of:
- calculating one error detection code covering both a transport layer header and a transport layer payload;
- compressing said transport layer header in accordance with said header compression algorithm;
- including said error detection code with said compressed transport layer header;
- and
- transmitting said compressed transport layer header.
A system for replacing a transport layer checksum in a header compression algorithm, said system comprising:
- an error detection code calculator for calculating one error detection code covering both a transport layer header and a transport layer payload;
- a header compressor for compressing said transport layer header in accordance with said header compression algorithm;
- and
- a transmitter for transmitting said compressed transport layer header.
