3.2.3 OAM Blocks
The Operation And Maintenance (OAM) is responsible for operation and maintenance in
the eNB. The OAM is configured with PM, FM, CM, SNMP, SwM, TM, Web-EMT and
OSAB.
The major functions of the OAM are as follows:
Performance Management (PM)
PM collects and provides performance data so that the operator of the management system
can determine the performance of the LTE of eNB. The PM collects events and
performance data during system operation and transmits them to the management systems.
The main functions are as follows:
 Collecting statistics data
 Storing statistics data
 Transmitting statistics data
Fault Management (FM)
The FM performs the fault and status management functions on the eNB’s hardware and
software. The FM applies filtering to a detected fault, notifies the management system, and
reflects the fault severity and threshold changes in the fault management.
The main functions are as follows:
 Detecting faults and reporting alarms
 Viewing alarms
 Alarm filtering
 Setting alarm severity
 Setting alarm threshold
 Alarm correlation
 Status management and reporting
 Status retrieval
Configuration Management (CM)
The CM manages the eNB configuration and parameters in PLD format and provides the
data that the software blocks need. Through the command received from SNMP/CLI/Web-
EMT, the CM provides the functions that can grow/degrow the system configuration, and
display/change the configuration data and operation parameters.
The main functions are as follows:
 Retrieval and change of configuration information, and grow/degrow function
