ABSTRACT:
A method, apparatus, system, and computer software for compressing and decompressing a message for transmission. The method of compressing a text message for transmission may include parsing text strings and encoding numerical values with a binary representation and analyzing values of the text strings and populating a session specific codebook with partial strings from the values. The method of compressing a message for transmission may also include parsing the message with a template and generating at least one substring to be transmitted; parsing the at least one substring with entries in a session specific codebook and generating a first part of the compressed message; populating the session specific codebook with entries for unknown field values; parsing any unmatched substrings with entries from a first static dictionary and generating a second part of the compressed message; parsing any still unmatched substrings with entries from a second static dictionary and generating a third part of the compressed message; compressing a remainder of the substrings with a compression algorithm; and combining the first part, the second part, and the third part of the compressed message to obtain a compressed message for transmission.
