WRAN Training Team


NodeB OM is used to manage, monitor and

maintain the software, hardware and

configuration.

The NodeB supports two OM platforms:

LMT and M2000.

The NodeB provides OM functions such as

equipment, software and alarm

management.


Upon completion of this course, you will be able to:

Know the structure of NodeB operation and

maintenance system

Master NodeB operation and maintenance f

unctions

Manage NodeB routine maintenance

Function of NodeB Operation and Maintenance


Alarm types:

Fault Alarm

−The alarms generated in case of hardware equipment faults or major

function failures. After the fault has been removed ,the system will

report a cleared alarm. One clear alarm corresponds to one fault alarm.Event Alarm

−The accidental alarms indicating that the system is in alarm state for a

while. There is no cleared alarm for event alarms. Classified by network management

Alarm severity

Critical Alarm

− The critical Alarm has an impact on the service provided by the

system. It requires timely handling

Major Alarm

− The major alarm affect QoS. It requires immediate handling.

Minor Alarm

− The minor alarm does not affect QoS. It requires handling at a

proper time against potential faults.

Warning Alarm

− The warning shows a potential error that may affect service. It

may require handling in some cases.

Blocking/Unblocking Cell

Blocking cell: BLK LOCELL

− Blocking a cell is used to transfer the service on the cell to a

neighboring cell and then close the Tx channels of the cell, the cell

resources are not available after this operation.

Unblocking cell: UBL LOCELL

− NodeB will open the Tx channels and restore the administration status

of the cell. The cell is in service.

Auditing resource: ADT RES

Use this command to request RNC for audit on the logical resources

between RNC and NodeB.

Note: In this way, you can maintain faulty NodeB without interrupting service

Software Management

Software Description

BootROM software The BootROM software refers to the software bound with hardware. It provides basic device

drive function and can be started and updated manually.

The BootBOM software is a re-writable storage medium, which is used to store binary data, t

hat is, the machine codes. All the boards on the NodeB have such BootROM software.

The file name of the BootROM software is Firmware.csp.

NodeB software For macro NodeBs, the main board has NodeB software version for the master CPU and slav

e CPU.

The file name of the NodeB software is Software.csp.

Cold patch

software

The NodeB cold patch can upgrade a specific board or module to improve functions or to fix s

ome problems.

The file name of the cold patch is NBPatch.pck.

Hot patch software The NodeB hot patch is also named online patch, which can upgrade the NodeB without inter

rupting its operation. The hot patch is used to improve NodeB functions or to fix some proble

ms.

The file name of the hot patch is NBHPatch.pck.
