Title: Processing method for device alarm of mobile communication system
Inventor: LEE SANG YEONG
IPC: H04B17/40
Filed: 2001-12-20
Abstract: PURPOSE: A method for processing a device failure of a mobile communication system is provided to preferentially report an alarm most affecting normal operation of a system when a specific device has a plurality of alarms, thereby promptly grasp the corresponding failure and taking necessary measures. CONSTITUTION: A hardware device sets up a bit corresponding to alarm contents of the hardware device as '1' at an alarm scan register area when a failure occurs in the hardware device(S201). A failure block masking-processes lower alarms except a top level alarm when alarms generate(S202). The failure block reports only the top level alarm to a base station manager(S203). In releasing the failure, the hardware device sets up the bit corresponding to the alarm contents of the hardware device as '0' at the alarm scan register area(S211). When the top level alarm is released, the masked lower alarms are unmasking-processed(S212). The hardware device reports the released alarm to the base station manager and reports masking-processed alarms after unmasking-processing(S213).
