METHOD FOR SYNCHRONIZING TIME IN MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE: A method for synchronizing time in a mobile communication system is provided to supply a function of adjusting a TOD(Time Of Day) to self time in a main processor when the TOD is supplied, thereby simply performing time synchronization without using a GPS receiver. CONSTITUTION: When a synchronization program starts, a synchronization program reads shape information from firmware(300), and sets a software interrupt initial value(302). The synchronization program sets a virtual clock interrupt initial value for synchronization(304), and sets a virtual clock initial value for correction(306). The synchronization program decides whether the program is mounted on a main processor from the read shape information(308). If so, the synchronization program converts into a main processor execution mode(310). If the program is mounted on a sub processor, the synchronization program converts into a sub processor execution mode(312).
