PURPOSE: A method for displaying advertisement by using a short message service of a mobile telecommunication terminal is provided to download advertisement without heavy charge for a telephone call. CONSTITUTION: An MPU determines whether a display list pointer is null(602). The MPU duplicates the display list pointer to a temporary list pointer(603). If, at least, one advertisement data to be displayed exists, the MPU reads current time information(604). It is determined whether advertisement data to be displayed exist in the next display list(606). If one exists, the MPU determines whether duration time is larger than or same as the current time(607). If so, the MPU compares duration time with old duration time(608). If duration time and old duration time are not identical, the MPU calls a display data build function by applying an advertisement display instruction and the temporary list pointer(610). The MPU duplicates the duration time to the old duration time(612). If two or more exist, the MPU determines whether rotation time and duration time are larger than the current time(614). If the rotation time is larger than or same as the current time and the duration time is larger than or same as the current time, the MPU compares the rotation time with the old rotation time(616). If not identical, the MPU calls the display data build function by applying the advertisement display instruction and the temporary list pointer(618). The MPU duplicates the rotation time to the old rotation time(620). The temporary display list pointer is moved to the current display pointer and the value is same as null(622). If null, the current display pointer is duplicated to the temporary list pointer(624). The MPU updates the rotation time and the duration time(626). If not null, the MPU moves the temporary list pointer to the connected pointer and the connected pointer is duplicated to the temporary pointer(628).
