DEVICE INSIDE BASE STATION OF MOBILE COMMUNICATION SYSTEM SWITCHING METHOD

摘要

PURPOSE: A device inside a base station of a mobile communication system switching method is provided to minimize the event that a call is cut off by deformation of the device. CONSTITUTION: The device switching method comprises the steps of: applying the switching order with redundancy if an error generates at a TSU(20) while watching RFC state at all time at a site alarm card assembly(SACA) that is installed in a base station(200)(Step 1); and applying a returning order to redundancy if a RFC(23) returns to the normal state while periodically examining all RFC that is mounted to a BCP after applying the step 1(Step 2).
