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 sho11 message 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, whereto each data segment is smaller than the predetermined size;

encoding tile data segments; and

sending tile plurality of data segments along with a serial number of each data segment over the wireless communication network,

wherein the preprocessing step further comprising the steps for;

stripping off format data from the data to reduce the size of the data;

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

performing a loss), processing if the data are graphic data;

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

sampling the audio data based on a proprietary frequency if the data are audio data;

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.

2. 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.

3. The method of claim 1, whereto the file step for sampling the audio data being ill an interleaved format if the data are graphic data.

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

5. 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.
