Abstract

The present disclosure is directed towards systems and methods for compressing messages, such as Short Message Service (SMS) or text messages between fixed or mobile devices through communications networks. The data of, for example, SMS messages is compressed and forwarded through a communication network to an appliance having a processing unit. The appliance decompresses the message and controls its delivery through network communication devices, where the decompressed SMS message is forwarded to its destination.

Claims

1. A method for compressing short text data, the method comprising;

receiving, by a device, a text to be compressed, the text comprising a plurality of symbols;

identifying, by the device, a dictionary for each symbol of a plurality of symbols, the dictionary comprising a list of the symbols sorted in decreasing probability of occurring a predetermined distance from a symbol for which the dictionary was generated; and

encoding, by the device, a first symbol in a first position of the text with the dictionary corresponding to the symbol the predetermined distance away from the first position.

2. The method of claim 1, wherein the predetermined distance is a text position immediately after the symbol for which the dictionary was generated.

3. The method of claim 1, further comprising generating, by the device, a generic dictionary, wherein the generic dictionary comprises a list of symbols, ordered in decreasing probability of occurring at the beginning of words of a language.

4. The method of claim 3, further comprising encoding, by the device, the symbol the predetermined distance from one of a space or a special character with the default dictionary.

5. The method of claim 3, further comprising encoding, by the device, the symbol at the beginning of the text with the generic dictionary.

6. The method of claim 1, further comprising encoding, by the device, each symbol of the text with the dictionary of the symbol the predetermined distance away from the symbol to be encoded.

7. The method of claim 1, wherein the symbol comprises one of a letter, a number, a group of symbols, or a special character.

8. The method of claim 1, further comprising generating, by the device, a separate dictionary for each letter of a language and a numerical dictionary for numbers.

9. The method of claim 1, further comprising setting, by the device, a first entry of the plurality of dictionaries to be a space.

10. The method of claim 1, further comprising encoding, by the device, a second symbol in a second position of the text with the dictionary corresponding to the symbol the predetermined distance away from the second position.

11. A device for compressing short text data, the device comprising;

a receiving module configured to receive a text to be compressed; and

an encoding module configured for;

identifying, a dictionary for each symbol of a plurality of symbols, and

encoding a first symbol in a first position of the text with the dictionary corresponding to the symbol the predetermined distance away from the first position.

12. The device of claim 11, wherein the predetermined distance is a text position immediately after the symbol for which the dictionary was generated.

13. The device of claim 11, wherein the encoding module is further configured to generate a generic dictionary, the generic dictionary comprising a list of symbols, ordered in decreasing probability of occurring at the beginning of words of a language.

14. The device of claim 13, wherein the encoding module is further configured to encode the symbol the predetermined distance from one of a space or a special character with the default dictionary.

15. The device of claim 13, wherein the encoding module is further configured to encode the symbol at the beginning of the text with the generic dictionary.

16. The device of claim 11, wherein the encoding module is further configured to encode each symbol of the text with the dictionary of the symbol the predetermined distance away from the symbol to be encoded.

17. The device of claim 11, wherein the symbol comprises one of a letter, a number, a group of symbols, or a special character.

18. The device of claim 11, wherein the encoding module is further configured to generate a separate dictionary for each letter of a language and a numerical dictionary for numbers.

19. The device of claim 11, wherein the encoding module is further configured to set a first entry of the plurality of dictionaries to be a space.

20. The device of claim 11, wherein the encoding module is further configured to encode a second symbol in a second position of the text with the dictionary corresponding to the symbol the predetermined distance away from the second position.
