Problems solved by technology

[0003] However, when using this compression algorithm, languages ​​such as Korean characters and Chinese are relatively redundant because most of them have the characteristics of redundancy, so the compression efficiency is relatively low, and more memory is required, and there is a problem that the storage space cannot be effectively reduced.

Embodiment Construction

[0012] For the convenience of description, the method for compressing 2-byte character data in the present invention is described by taking Korean as an example. But the same applies to languages ​​marked in 2 bytes such as Chinese, Japanese, etc. Therefore, in this embodiment, only the compression of Korean language is described, but the present invention is not limited to Korean language, which is obvious to those skilled in the art.

[0013] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0014] figure 1 It is an operation flowchart of the method for compressing 2-byte character data in one embodiment of the present invention, and the related situation will be described below.

[0015] First, initialize the maximum number of character strings (N7), the number of code words (N2), the initial dictionary entry number (N5), etc., store the characters with high frequency numbers in the basic dictionary table, and regi...

Abstract

A method for compressing 2-byte character data is provided to save a storage space by compressing a 2-byte text message and storing the compressed data. The maximum number of character strings, the number of code words and initial dictionary entry number are initialized, characters with high frequency are stored in a basic dictionary table, and a variable indicating a next codeword to be registered is initialized(S101). An additional compression-available codeword is stored in a supplementary dictionary table including the basic dictionary table, and the variable indicating the next codeword to be registered is re-initialized(S102). Message data is sequentially inputted and if the inputted data is included in the compression-available codeword, a corresponding code is searched from the dictionary table and outputted(S103). It is checked whether the corresponding code is in the dictionary(S104). It is determined whether it is the end of the data(S105). If so, a flushing process is performed(S106).

Description

technical field [0001] The present invention relates to a kind of compression method of 2-byte character data, relate to a kind of in order to reduce the information storage space of SMS (Short Message Service) and EMS (Enhanced Messaging Service) in mobile communication terminal machine, utilize 2 bytes Compression method for 2-byte character data of byte character compression algorithm. Background technique [0002] Generally, customers use the information sending and receiving functions (SMS, EMS) of mobile communication terminals to exchange various information. Most mobile communication terminals hardly compress such information, and terminals that perform partial compression only use compression algorithms suitable for English letters. [0003] However, when using this compression algorithm, languages ​​such as Korean characters and Chinese are relatively redundant because most of them have the characteristics of redundancy, so the compression efficiency is relatively...
