System and method for communicating with temporary compression tables

A communication entity for communicating messages using a communication protocol, said communication entity comprising:

• a decompressor for decompressing a communication message;
• at least one dictionary in communication with said decompressor;
• a sender table in communication with said decompressor, said decompressor retrieving first compression information from any of said at least one dictionary and said sender table, for said decompressing of said communication message;
• and
• a receiver dictionary in communication with said decompressor, said receiver dictionary storing second compression information related to the decompression of said communication message.

A communication apparatus for the compression and decompression of communication messages, said communication apparatus comprising:

• a compressor for compressing a transmitted communication message;
• a decompressor for decompressing a received communication message;
• a static dictionary in communication with said compressor and said decompressor;
• a dynamic dictionary in communication with said compressor and said decompressor;
• a receiver dictionary in communication with said compressor;
• and
• a sender table in communication with said decompressor, said compressor using any of said static dictionary, said dynamic dictionary, and said receiver dictionary for said compressing of said transmitted communication message, and said decompressor using any of said static dictionary, said dynamic dictionary, and said sender table for said decompressing of said received communication message.

A method for compressed message communication by a communication entity, said method comprising the steps of:

• compressing a first communication message, using first compression information from any of at least one dictionary and a receiver dictionary, to generate a first compressed communication message;
• storing second compression information related to said compressing of said first communication message in a sender table;
• transmitting said first compressed communication message to another communication entity;
• receiving a second compressed communication message from said another communication entity;
• and
• transferring said second compression information from said sender table to said at least one dictionary.

A method for compressed message communication by a communication entity, said method comprising the steps of:

• receiving a compressed communication message from another communication entity;
• decompressing said compressed communication message using first compression information from any of at least one dictionary and a sender table, to generate a first communication message;
• storing second compression information, related to said decompressing of said first compressed communication message, in a receiver dictionary;
• sending a second communication message to said another communication entity;
• receiving a third communication message from said another communication entity;
• and
• following reception of said third communication message, transferring said second compression information from said receiver dictionary to said at least one dictionary.
