Chapter 3 System Structure

LTE eNB System Description v2.0 45

Fault Management (FM)

The FM performs fault and status management functions on eNB’s hardware and

software. It applies filtering to a detected fault, notifies the management system,

and reflects the fault severity and threshold changes in the fault management. Also,

it operates on the master OAM board and call processing board.

The main functions of FM 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 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, CM provides the functions that can grow/degrow system

configuration, and display/change the configuration data and operation parameters.

The CM operates on the master OAM board.

The main functions of CM are as follows:

 Grow/degrow of system and cell

 Retrieval, change, grow & degrow of configuration information

 Retrieval & change of the call parameters

 Retrieval, addition, deletion, and change of neighbors

Simple Network Management Protocol (SNMP)

The SNMP is an SNMP agent for supporting a standard SNMP

(SNMPv2c/SNMPv3).

It performs interfacing with upper management systems and interoperates with the

internal subagents. When receiving a request for a standard MIB object from LSM,

the SNMP processes the request independently. When receiving a request for a

private MIB object, it transmits the request to the corresponding internal subagent.

The SNMP operates on the master OAM board.

The main functions of SNMP are as follows:

 Processing the standard MIB

When receiving a request for MIB-II object, the SNMP processes it
