Abstract

A method to enhance a mobile device'"'"'s ability to transmit short messages over a wireless communication network is provided. The method includes the steps for preprocessing a data according to it data type, fragmenting the data into a plurality of data segments if the data is larger than a predetermined size after being preprocessed and compressed, and transmitting the data segments from a sending terminal after encoding the data segments. The method also includes the steps of recombining the plurality of decoded data segments into a single data after receiving and decoding the data, and displaying the data as a single piece of data at a receiving terminal after decompressing and processing the data.

Claims

1. A method to enhance a mobile device'"'"'s ability to transmit data as short messages over a wireless communication network, the data having a type, comprising the steps for:

determining the type of the data;

preprocessing the data according to the type of the data;

compressing the preprocessed data according to a predefined algorithm;

fragmenting the compressed data into a plurality of data segments if the compressed data is larger than a predetermined size, wherein each data segment is smaller than the predetermined size;

encoding the data segments; and

sending the plurality of data segments over the wireless communication network.

2. The method of claim 1, wherein the preprocessing step further comprising the steps for:

performing a dictionary based preprocessing if the data are text data;

performing a lossy processing if the data are graphic data; and

performing a lossy processing if the data are audio data.

3. The method of claim 1, wherein the preprocessing step further comprising the step for stripping off format data from the data to reduce the size of the data.

4. The method of claim 1, wherein the preprocessing step further comprising the step for decolorizing the data to reduce the size of the data if the data are graphic data.

5. The method of claim 1, wherein the preprocessing step further comprising the step for sampling the data in an interleaved format if the data are graphic data.

6. The method of claim 1, wherein the preprocessing step further comprising the step for resizing the data if the data are graphic data.

7. The method of claim 1, wherein the preprocessing step further comprising the step for sampling the data according to a predefined frequency if the data are audio data.

8. The method of claim 1, wherein the compressing step further comprising the steps for:

performing a text-dictionary based mathematic compression if the data are text data;

performing a multimedia based characteristic compression if the data are graphic data; and

performing a multimedia based characteristic compression if the data are audio data.

9. The method of claim 1, wherein sending step further comprising the step for transmitting each data segment as a short message over the wireless communication network.

10. A method to enhance a mobile device'"'"'s ability to transmit data as short messages over a wireless communication network, the data having a type, comprising the steps for:

receiving a plurality of data segments from the wireless communication network;

decoding the plurality of data segments;

recombining the plurality of decoded data segments into a single data;

determining the type for the single data;

decompressing the single data into a decompressed data according to a predefined algorithm based on the type of the received data;

processing the decompressed data upon the type of the received data; and

displaying the processed data as a single piece of data.

11. The method of claim 10, the decompressing step further comprising the steps for:

performing a text-dictionary based mathematic decompression if the received data are text data;

performing a multimedia based characteristic decompression if the received data are graphic data; and

performing a multimedia based characteristic decompression if the received data are audio data.

12. The method of claim 10, wherein the processing step further comprising the steps for:

performing a dictionary based preprocessing if the received data are text data;

performing a lossy processing if the received data are graphic data; and

performing a lossy processing if the received data are audio data.

13. The method of claim 10, wherein the processing step further comprising the step for restoring format data into the received data if the received data have been processed.
