3) Minor ALM: It does not influence services or subscribers or call processing to
much degree. It does not require urgency in action.
In order to minimize the influences of the faults, BSM reports the classified faults in
details, and if necessary, the operator can isolate the corresponding fault blocks and
restore them. In addition, when faults occur, it helps to isolate faults and recover them
by figuring out the state accurately through the diagnosis function.
The diagnosis is divided into the following: 1) the Online diagnosis that is automatically
run without the operator’s request and the On-demand diagnosis that is run by the
operator’s command. The test function exists in the system separate from the diagnosis
function and the diagnosis function uses the performance result of the test function.
Online diagnosis can be changed using the operator’s MMC and Online diagnosis
starting point and end point can also be changed.
1.1.3. Performance Management of System
Performance and management functions of the system are classified into the following:
(1) the performance measurement function, (2) the performance evaluation
measurement adjusting function, and (3) the performance evaluation function
(performance evaluation and performance evaluation report using the designated
performance evaluation criteria). The criteria that can be used for the performance
evaluation are in general as follows:
 Throughput: it measures communication circuit and network node throughput.
In general, PDU (protocol data unit) measures the success rate of the
sending/transmission.
 Workload: It takes various actions to prevent overload. By setting the standard
for the workload, it prevents the overload.
 Others: it measures propagation delay, wait time, and response time, and
quality of service.
