Huawei GSM BSS O&M Concepts of Alarm Management To describe the concepts of the BSS alarm management, including the alarm types, alarm IDs, alarm severity, alarm flags, and types of network management.

Alarm Types The BSS alarms are classified into two types: fault alarms and event alarms. Fault alarms Fault alarms are generated when faults occur in the equipment, such as board faults. The fault alarms can be cleared through fault handling. Event alarms An event alarm indicates a predefined event that happens during the running of the devices, such as channel congestion. The alarm represents an instantaneous status of the system and the status may not be a fault. Some event alarms are re-sent periodically . Event alarms do not require handling.

11


Huawei GSM BSS O&M Different levels of alarms and their handling methods Alarm Severity

Definition

Troubleshooting

Critical alarm

Reporting faults that affect the services provided by the system These alarms need immediate treatment even during off-work period. For example, some equipment or resource breaks down.

Handle the faults immediately. Otherwise, the system may collapse.

Major alarm

Reporting faults that affect the Quality of Service (QoS). These alarms need treatment during working hours. For example, the performance of some equipment or resource deteriorates.

Handle the faults timely. Otherwise, the system may fail to perform some major functions.

Minor alarm

Reporting faults that are not serious enough to affect the QoS. These alarms need timely treatment or further observation to avoid worsening.

Find and clear any potential fault in time.

Warning alarm

Reporting faults that potentially threaten the system services. No handling is required.

Learn the running status of the system.
