SELF TESTING METHOD OF A CELLULAR PHONE, SPECIALLY WITH REGARDS TO TESTING WHETHER THE CELLULAR PHONE IS NORMALLY OPERATED, BY RECEIVING A JAVA SCRIPT-TYPE SELF TEST PROGRAM FROM A SERVER THROUGH A DOWNLOADING PROCESS

摘要

PURPOSE: A self testing method of a cellular phone is provided to receive a Java script-type self test program from a server through a downloading process, and to self test whether a cellular phone is normally operated, then to display tested results on a main LCD, so that a user can take necessary measures when a program is abnormal. CONSTITUTION: A cellular phone user accesses a random contents site to receive a program for testing a hardware device by using a Java script type, and stores the downloaded program in a flash memory(S1-S3). If the user commands the test program to be executed, the stored test program is copied into an RAM to be executed(S4,S5). The hardware device is tested, and test results are displayed on a main LCD(S6,S7).
