About This Chapter
The purpose of RAN routine maintenance is to ensure the reliability, stability, and optimum
operating status of the BSC6900 and NodeB. In addition, routine maintenance can prevent
potential accidents, identify and solve problems in time, and improve equipment reliability.
2.1 Scope
RAN routine maintenance is performed at the network management center to ensure the reliable
operation of the BSC6900 and NodeB.
2.2 Tools
The tools for RAN routine maintenance consist of the M2000 client and LMT.
2.3 Tasks and Intervals of RAN Routine Maintenance
Based on the maintenance frequency, routine maintenance is classified into daily, weekly, and
monthly maintenance.

2.1 Scope
RAN routine maintenance is performed at the network management center to ensure the reliable
operation of the BSC6900 and NodeB.
RAN routine maintenance is a process in which the BSC6900 and NodeB are monitored and
maintained. Generally, routine maintenance is performed through the M2000.
RAN routine maintenance does not include the routine maintenance of the M2000 or the site
maintenance.
To perform r outine maintenance on the M2000, see the M2000 Operator Guide.
2.2 Tools
The tools for RAN routine maintenance consist of the M2000 client and LMT.
M2000 Client
The M2000 client is used to monitor multiple NEs simultaneously.
NOTE
When the BSC6900 UMTS Sharing function is applied, the operating support systems (OSSs) of the
telecom operators are connected to the M2000 through the northbound interface. Accordingly, your
permissions are as follows:
l You have no permission to view the configurations, status, alarms, and performance of the cells of
other telecom operators.l You have the permissions to view the configurations, status, alarms, and performance of the common
resources but have no permission to modify them.
l You have the permissions not only to view the configurations, status, alarms, and performance of your
own cells but also to modify them.
LMT
The LMT is used to perform routine maintenance on a single NE.
When the M2000 client detects a fault in an NE, you can log in to the NE through the LMT to
locate, analyze, and rectify the fault.
2.3 Tasks and Intervals of RAN Routine Maintenance
Based on the maintenance frequency, routine maintenance is classified into daily, weekly, and
monthly maintenance.
2.3.1 Daily Maintenance Tasks
This section describes the daily maintenance tasks and provides reference for each task.
2.3.2 Weekly Maintenance Tasks
