 Fault detection: the function to monitor the faults on a regular
basis and write the error report.
 Fault diagnosis: the function to run a diagnosis on causes for
the corresponding faults. It regenerates the causes for errors,
analyzes the errors, and receives report on the causes for
errors from the corresponding error factors. Therefore, in
general, the system test function corresponds to the diagnostic
function.
 Fault handling: Faults can be handled by other parts of the
BSM system such as configuration management.
NE (Network Element) and intangible resources, which are mounted to the system, can
be managed as the status information such as Sector, FA, etc. In addition, BSM informs
to the operator the status information on the status management target accurately and
can inquire the status of the status management target in real time. Furthermore,
through the function to check memory, it can manage the appropriateness of the
memory and its use state online.
In case of the call resource state management, if problems occur in the corresponding
resources, BSM assists to provide the high-quality services by isolating them after
tests. It notifies the operator of the reasons for the errors so he/she can isolate them
and take proper measures to correct them.
When faults occur or when clearing faults, the corresponding information is reported to
the operator immediately through the use of the operator terminal, GUI, audible device,
Alarm panel, etc. The resources with faults are automatically excluded from services to
prevent the system quality degradation using the corresponding resources when
processing calls. Depending on the degree that faults affect the system, they are
classified into minor, major, and critical and then the operator is notified.
1) Critical ALM: It has the fatal influence on the system function. Therefore,
regardless of the time it occurs, it requires the urgency in action.
2) Major ALM: It affects the system profoundly. It indicates abnormal operation of
the main circuits, or fault occurrence. This fault should be notified to the operator
so that he/she can perform a test on the functions or restore them.
