benefits to Evolved Universal Terrestrial Radio Access Network (E-UTRAN), including:
 Reduced service delay
 Higher user data rates
 Increased spectral efficiency
 Optimized support for packet services
 Improved system capacity and coverage
LTE has flexible bandwidths, enhanced modulation schemes, and effective scheduling. In
addition, LTE allows operators to use both original and new spectral resources to provide data
and voice services.
1.1 Positioning
Focusing on customer-oriented innovation, Huawei launches a series of LTE products in its
SingleBTS product portfolios, including BTS3900 LTE (indoor), BTS3900A LTE (outdoor),
and BTS3900L LTE (indoor). These base stations fully utilize Huawei platform resources and
use a variety of technologies to meet the challenges of mobile network development.
The E-UTRAN NodeB (eNodeB) is used for radio access in the LTE system. The eNodeB
mainly performs Radio Resource Management (RRM) functions such as air interface
management, access control, mobility control, and User Equipment (UE) resource allocation.
Multiple eNodeBs constitute an E-UTRAN system.
Figure 1-1 shows the eNodeB position in the network.

Smooth Evolution
 As SingleRAN solutions, the BTS3900 LTE, BTS3900A LTE, and BTS3900L LTE
enable smooth network evolution and reduce the cost of LTE site deployment by sharing
Huawei SingleBTS hardware platform and equipment with other base stations:
− BTS3900/BTS3900A/BTS3900L GSM
− BTS3900/BTS3900A/BTS3900L WCDMA
− BTS3900/BTS3900A/BTS3900L CDMA
 The BTS3900/BTS3900A/BTS3900L LTE can share the network with GSM or UMTS
base stations and support handovers between LTE and the PS domain of the
GERAN/UTRAN/CDMA2000. This facilitates LTE network deployment in the existing
GSM or UMTS network.
 The BTS3900/BTS3900A/BTS3900L LTE supports RAN sharing. Different operators
can share the RAN network, reducing capital expenditure (CAPEX).
 The BTS3900/BTS3900A/BTS3900L LTE enables GSM, UMTS, and LTE modules to
share one indoor macro cabinet or outdoor radio frequency (RF) cabinet, which saves
installation space and facilitates resource utilization.
 The BBU3900 is the baseband unit (BBU) of the BTS3900/BTS3900A/BTS3900L LTE.
The BBU3900 supports multi-mode applications. Therefore, boards of different modes
can be installed in one BBU3900.
Large Capacity, Extensive Coverage, and High Throughput
 The BTS3900/BTS3900A/BTS3900L LTE provides large capacity. A single eNodeB
supports a maximum of 3600 UEs in RRC_CONNECTED mode.
 The BTS3900/BTS3900A/BTS3900L LTE provides extensive coverage. It can cover a
maximum cell radius of 100 km when using functions such as multi-antenna RX
diversity and uplink inter-cell interference coordination (ICIC).

(MIMO), and ICIC.
Enhanced SON Function
 Automatic configuration
The BTS3900/BTS3900A/BTS3900L LTE can automatically obtain connection
parameters, download software, configure data, conduct tests, and upload information.
This facilitates preparation for data configuration, reduces manual handling during site
deployment, and minimizes operational expenditure (OPEX).
 Automatic Neighbor Relation (ANR)
The BTS3900/BTS3900A/BTS3900L LTE can automatically maintain the integrity and
validity of the neighboring cell list by automatically detecting missing neighboring cells
and evaluating neighboring cell relationships. This increases handover success rates and
reduces the cost of network planning and optimization.
 Automatic detection of Physical Cell Identifier (PCI) conflicts, sleeping cells, and
antenna faults
PCI conflicts, sleeping cells, and antenna faults are automatically detected and reported,
reducing the workload of manual identification of network faults.
Comprehensive IP Transport
 Various transmission ports are provided, such as FE/GE electrical ports, FE/GE optical
ports, and E1/T1 ports.
 Internet Protocol (IP) transport is supported. In addition, diversified network topologies
are supported, such as star, chain, and tree topologies.
 Multiple Quality of Service (QoS) mechanisms are applied to provide high capacity,
implement differentiated services, and meet the QoS requirements of services.
Easy Maintenance and Low OPEX
The BTS3900/BTS3900A/BTS3900L LTE has only two types of basic modules. The basic
modules and auxiliary devices can be combined in many ways to meet different requirements.

functions. At the same time, it can synchronize data with the M2000.
− The eNodeB performs a complete check on all the configuration commands delivered
to the eNodeB, avoiding impact of maloperations.
− The Configuration Management Express (CME), one of the components on the
M2000, supports configuration rollback in batches. Therefore, when the user
discovers abnormal running or malfunctions of the system after the configuration, the
user can run a rollback command to restore data.
 Excellent scalability
− Configuration management by using the northbound network management system
(NMS) is supported.
− The user can add, remove, or modify eNodeB configurations by running MML
commands.
− The user can use MML commands and the iSStar of the M2000 to customize
functions of the M2000, for example, to customize troubleshooting procedures.
5.3.2 Fault Management
The fault management of the eNodeB provides easy fault location, high reliability, and
various tracing and monitoring methods.
 Easy fault localization

and the required tools.
− For the KPI level service failures, the eNodeB offers methods to rectify faults, which
helps the user to locate and solve the problem quickly and accurately.
− The eNodeB supports the alarm correlation function. For all the faults caused by a
radical cause, the eNodeB reports only one radical alarm and its eventual impact on
the system. The user can easily locate the radical cause of the alarm by referring to
the alarm correlation, and then rectify the fault.
 High reliability
− Fault detection is comprehensive and accurate. The eNodeB provides the fault
detection function for the hardware, software, antenna, transmission, cell, and
environment, in which the fault detection for the environment is performed in terms
of door status control, infrared, smoke, water damage, and temperature. In addition,
the system allows customization of external alarms.
− Fault isolation and self-healing of the eNodeB also ensure that the local failure does
not affect the other parts of the system. In addition, the eNodeB can set up the cell
again with degraded specifications to minimize the impact of the failure on services.
 Various tracing and monitoring methods
− The eNodeB supports various tracing functions to check the compatibility of
interfaces. The tracing functions are to trace the standard signaling of one UE in the
entire network, in a cell, or on standard interfaces. The user can trace operations of

26
the eNodeB on the LMT/M2000 in real time, or browse and analyze tracing results
later.
− The eNodeB supports the real-time performance monitoring in GUI mode,
facilitating the user to locate performance failures speedily. The user can monitor the
transmission quality of user-level or cell-level air interface, air interface performance
and interference, and quality of transmission links in real time.
− The eNodeB supports one-click collection and upload of system logs. When the user
fails to locate or rectify faults, this function helps the user to collect the detailed field
information. Then the user can provide the fault information to Huawei Customer
Service Center for more efficient troubleshooting.
5.3.3 Performance Management
The performance management features multiple monitoring and reporting periods and
appropriate measurement point allocation, which meets requirements in different scenarios.
 Multiple monitoring and reporting periods
− The eNodeB can collect performance counters every 15 or 60 minutes. The default
value is 60 minutes.
− The eNodeB supports real-time monitoring of KPIs for a duration of 1 minute.
 Appropriate measurement point allocation
− The eNodeB supports performance measurement of system-level or cell-level, of
neighboring cells, on interfaces, and of device usage, which helps the user to locate
faults.
5.3.4 Security Management
The security management provides network-level and user-level security services.
The eNodeB supports the following services to ensure the security, integrity, and availability
of the system:
 Encryption of key information of the user
 User account management and authentication
 Control over access rights of the user
 Support of security protocols such as File Transfer Protocol Over SSL (FTPS), Secure
Socket Layer (SSL), and Internet Protocol security (IPSec)
 Automatic record of the account usage information
 Security certificate
