Communication system and method utilizing request-reply communication patterns for data compression

A communications device for facilitating compressed message communication, said communications device comprising:

• a receiver unit;
• a transmitter unit;
• a processor;
• and
• memory having stored therein at least one dictionary and program software having instructions which, when executed by the processor, causes the communications device to:
• receive, by said receiver unit, a first communication message from another communications device, said communication message having a compressed portion therein;
• decompress, using said at least one dictionary, said compressed portion of said first communication message;
• and
• add said compressed portion to said at least one dictionary.

A communications device, comprising:

• a receiver unit;
• a transmitter unit;
• a processor;
• and
• memory having stored therein at least one dictionary and program software having instructions which, when executed by the processor, causes the communications device to:
• compress, using said at least one dictionary, a portion of a communication message to obtain a compressed portion thereof;
• transmit, by said transmitter unit, said communication message having the compressed portion to another communications device;
• and
• add, to said at least one dictionary, the compressed portion of said communication message upon reception, by said receiver unit, of a second communication message by said another communications device.

A communication system for facilitating compressed message communication, said communication system comprising:

• a first communication entity for sending a first communication message, said first communication entity comprising:
• a first dictionary;
• a first compressor in communication with said first dictionary, said first compressor using said first dictionary to compress a portion of a first communication message to produce a first compressed communication message;
• and
• a first transmitting means in communication with said first compressor, said first transmitting means transmitting said first compressed communication message;
• and
• a second communication entity, in communication with said first communication entity, for receiving said first compressed communication message, said second communication entity comprising:
• a first receiving means for receiving said first compressed communication message;
• a second dictionary;
• a first decompressor, in communication with said first receiving means and said second dictionary, said first decompressor decompressing, said first compressed communication message using said second dictionary to reproduce said first communication message;
• and
• a first updating means, in communication with said decompressor and said second dictionary, said first updating means updating said portion of said first communication message to said second dictionary.
