Method and apparatus for compressing and decompressing messages
First Claim
1. A method of compressing messages, in particular messages intended to be displayed on a telecommunications terminal, in particular a portable telephone, wherein, with said messages being made up of words themselves made up of characters, the method comprising:
- reading in said messages;
compiling an encoding table for compressing words, causing each compressed word represented by its rank in the table to correspond to a “
semi-compressed”
word made up of a sequence of compressed characters corresponding to the word;
compiling an encoding table for compressing characters, causing each compressed character represented by its rank in the table to correspond to a non-compressed character;
forming compressed messages from the compressed words.

Abstract
This method of compressing messages, in particular messages intended to be displayed on a telecommunications terminal, in particular a portable telephone, is essentially characterized in that, with said messages being made up of words themselves made up of characters, it includes compiling two encoding tables, namely an “encoding table for compressing words”, causing each compressed word represented by its rank in the table to correspond to a “semi-compressed” word made up of a sequence of compressed characters corresponding to the word, and an “encoding table for compressing characters”, causing each compressed character represented by its rank in the table to correspond to a non-compressed character.

7. A method for decompressing messages, in particular messages intended to be displayed on a telecommunications terminal, in particular a portable telephone, wherein, with said messages being made up of words themselves made up of characters, the method comprising:
-
reading in compressed messages;
addressing two encoding tables respectively with compressed words, an encoding table for compressing words, and with compressed characters, an encoding table for compressing characters;
causing each compressed word represented by its rank in the encoding table for compressing words to correspond to a “
semi-compressed”
word made up of a sequence of compressed characters corresponding to the word;
causing each compressed character represented by its rank in the encoding table for compressing characters to correspond to a non-compressed character; and
forming said messages. - View Dependent Claims (8, 9)

10. Apparatus for decompressing messages, in particular messages intended to be displayed on a telecommunications terminal, in particular a portable telephone, wherein, with said messages being made up of words themselves made up of characters, the apparatus includes:
-
a memory containing two encoding tables, namely an encoding table for compressing words and an encoding table for compressing characters;
memory addressing means for addressing the two tables with compressed words and with compressed characters and causing each compressed word represented by its rank in the encoding table for compressing words to correspond to a semi-compressed word made up of a sequence of compressed characters corresponding to the word, and causing each compressed represented by its rank in the encoding table for compressing characters to correspond to a non-compressed character. - View Dependent Claims (11, 12)
