Fault management enables the system operator to detect and respond to network
element faults within the system. The OMC provides fault management by using
Network Management agents that are resident on the various network elements to
pass events to the OMC. The events are reported and identified by priority level. The
system operators are able to filter the reporting of events based on priority (severity).
For example, if a power amplifier fails on a BR, the BR will send an event message
to OMC indicating a failure exists. The system operator can then send a technician.
Alarms and Events are stored on the OMC for future reference. If a higher order
management Network Maintenance Computer (NMC), is connected to the OMC
through a LAN, the event stream can be directed to the NMC for correlation with
other events not reported to the OMC.
Performance
Management
The performance management function controls the collection and presentation of
metrics to the system operator. These statistics files are stored in a database on the
OMC for the creation of reports. There are several generic reports that can be
selected for local analysis. The statistics files can be transferred to a higher order
manager such as an NMC. Metrics are gathered in four broad categories:
• Call Processing
• System Performance Metrics
• Link Layer Communications Metrics
• Meta-management Metrics.
Call Processing metrics are concerned with the number, duration and quality of calls
placed by the end-user for the various types of services available on the network.
System Performance metrics relate to service-oriented status and events such as
availability and outage impact.
The Link Layer Communications metrics provide information on the functional
operation of the radio links as discussed in Fault Management of this section.
The Meta-management statistics help the system operators control the impact of the
management system on the call processing system.
Configuration
Management
Configuration Management is monitoring and control of system and subsystem
components for state, software release, and components. The system configuration
databases of the DAP, EBTS, BSC, MDG and APDs are downloaded from the OMC.
These databases change as the physical configuration of the network expands to
accommodate growth. This configuration management relates to:
