1 Introduction
1.1 Positioning
The rapid development of mobile communication technology brings sharp growth in the
number of mobile phone users. This growth creates increasingly high requirements for
network quality. Besides enhancing network coverage, operators also need to increase
network capacity to meet rapid increases in traffic volume.
In many hot spots, insufficient of network capacity and the existence of blind spots greatly
affect user experience. To solve these problems, operators urgently need an accurate and
low-cost coverage solution with flexible site deployment.
Following the philosophy of continuous innovation based on customers’ requirements,
Huawei unveils the industry-leading WCDMA mini base station BTS3902E. Characterized by
its small size, light weight, plug-and-play functionality, auto-configuration, and no
requirements for shelter or equipment room, the BTS3902E is flexible in site acquisition and
deployment, making it a quick and flexible site solution for operators.
The BTS3902E is a bi-carrier product. Figure 1-1 shows the unit.

4 Operation and Maintenance
BTS3902E operation and maintenance (O&M) covers management, monitoring, and
maintenance of the software, hardware, and configuration of BTS3902Es. In addition,
BTS3902Es allow diversified O&M modes in different scenarios.
4.1 Operation and Maintenance Modes
The BTS3902Es support near-end, far-end, and reverse operation and maintenance (O&M).
In near-end O&M mode, maintenance personnel log in the local maintenance terminal
(LMT) through a local Ethernet maintenance port to maintain BTS3902Es.
In far-end O&M mode, maintenance personnel centrally maintain BTS3902Es on the
M2000 or LMT in the radio network controller (RNC) equipment room or operation and
maintenance center (OMC).
In reverse maintenance mode, maintenance personnel maintain a BTS3902E under the
same RNC as the current BTS3902E through a local Ethernet service port on the LMT.
The IP route between the current BTS3902E and the other BTS3902E is established by
the RNC.
Figure 4-1 shows the O&M system of BTS3902Es.

The O&M system of BTS3902Es consists of the following elements:
LMT: is mainly used to locally or remotely maintain BTS3902Es and configure data.
BTS3902E: is the O&M object.
M2000: short for iManager M2000 Mobile Element Management System, which
centrally manages Huawei network devices; the M2000 also remotely and centrally
manages multiple base stations.
CME: short for Configuration Management Express, which can configures and manages
data for multiple base stations.
BTS3902E O&M modes have the following features:
Supports the Dynamic Host Configuration Protocol (DHCP) andAdaptive and Active
Cache Pool (AACP). When no data is configured for the system or when the system is
faulty, the O&M channel can be automatically set up. This enhances the system
reliability and facilitates remote troubleshooting.
Supports configuration baseline, simplifying the configuration rollback process and
improving configuration rollback reliability.
Provides a comprehensive system self-check function, omitting local software
commissioning.
4.2 Operation and Maintenance Functions
The OM subsystem of the BTS3902E provides functions such as commissioning management,
equipment management, software management, alarm management, security management,
and environment monitoring.
4.2.1 Commissioning Management
Commissioning management provides the following functions:
Equipment performance tests, such as CPU usage test, clock source quality test, and
power test
Service performance tests, such as uplink channel scanning and statistics for service
resource usage
4.2.2 Equipment Management
Equipment management consists of equipment maintenance and data configuration.
Equipment management has the following functions:
Equipment maintenance includes the maintenance of equipment, for example, managing
the status of equipment, performing self-check on the equipment, and calibrating the
clock.
Data configuration includes configuration, query, and backup of equipment parameters,
for example, configuring the parameters of the NodeB hardware, parameters of the
NodeB clock, algorithm parameters, and RF parameters.
4.2.3 Software Management
Software management provides the following functions:

Activating the software
Checking the compatibility of software and hardware versions
Managing versions, for example, querying hardware and software versions
Upgrading the software version, cold patch, and hot patch
4.2.4 Alarm Management
Alarm management involves equipment alarm management and environment alarm
management.
Equipment alarm management
The alarm management system detects and reports information about faults in real time.
The LMT or M2000 then displays the alarm information and provides appropriate
handling suggestions.
The alarm management system of the M2000 connects to an alarm box through a serial
port and supports audible and visual alarms through the LEDs or the alarm box. The
maintenance personnel can subscribe to specific alarms. When related alarms are
generated, the alarm information is forwarded to the handsets or pagers of the
maintenance personnel so that they can rectify the faults in time.
Environment alarm management
Generally, equipment rooms of NodeBs are unattended and distributed over a large area.
The equipment works in a relatively adverse environment, and emergency cases may
incur. To help you handle such emergencies, the BTS3902E provides a complete alarm
management system.
Alarm management provides the following functions:
Alarm detecting
Alarm reporting
Alarm shielding
Alarm acknowledging
Alarm pre-processing
Alarm correlation processing
Alarm help processing
4.2.5 Security Management
The operation rights of maintenance personnel are classified into multiple levels when both
NodeB and M2000 are applied. This ensures that the running equipment is free from
misoperations.
4.2.6 Environment Monitoring
The environment monitoring system provides customized solutions regarding door control,
infrared, smoke, water immersion, humidity, and temperature.
