File construction for mobile communication device including machine-language-code execution segment and file execution method using the same

Abstract

The present invention relates to a file construction for mobile communication device including an execution segment in form of machine language codes and a file execution method using the same, whereby a file in accordance with the present invention comprises a header, a file execution segment formed in machine language codes, and a resource segment to be selected by languages; wherein the header includes data for performing one or more of the functions of: 1) verifying reliability/validity of the file, 2) restricting use of the file (by period of the use, by times of the use), and 3) automatic updating of the file. The file construction and the file execution method as per the present invention enable to enhance execution speed of a program for mobile communication device and to reduce storage space for such program; while functions such as verification of validity of the file, limiting use of the file, updating of the file can be performed using various data contained in the file header.
