1 BTS3900/BTS3900A/BTS3900L LTE Overview

Long Term Evolution (LTE) is an evolved telecom standard. It provides various technical

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.

1.2 Benefits

Advanced BS Platform, GSM and UMTS Co-Network, RAN Sharing, and 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).

The BTS3900/BTS3900A/BTS3900L LTE provides high throughput. It can provide a

maximum throughput of 450 Mbit/s in the downlink and 300 Mbit/s in the uplink when

using functions such as 64QAM, uplink and downlink multiple-input multiple-output

(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.

This centralized installation mode reduces maintenance on the tower and helps cut OPEX for

operators.

5 Operation and Maintenance

5.1 Overview The BTS3900/BTS3900A/BTS3900L, which has all OM functions of eNodeBs, is one of the

eNodeB product portfolios launched by Huawei. The eNodeB supports the OM system that is

based on the man-machine language (MML) and the Graphical User Interface (GUI). The OM

system enables a hardware-independent OM mechanism and provides powerful OM functions

to meet various OM requirements.

The eNodeB supports local maintenance and remote maintenance. In the OM system, the

maintenance terminal supports the Virtual Local Area Network (VLAN), and can access the

eNodeB using the Intranet or Internet, which makes maintenance more convenient and

flexible.

5.2 OM System

Figure 5-1 shows the OM system of the eNodeB.





24

Figure 5-1 OM system

The OM system consists of the LMT and the iManager M2000 (M2000 for short). The LMT

is used to maintain a single eNodeB. To perform maintenance operations, you can connect the

LMT to the eNodeB by using an Ethernet cable (local maintenance) or IP network (remote

maintenance). The M2000, a mobile element management system provided by Huawei, is

used to remotely maintain multiple eNodeBs of different software versions.

The functions of the OM system are as follows:

The LMT performs functions such as data configuration, alarm monitoring,

commissioning, and software upgrade. The LMT supports both MML and GUI modes.

The M2000 performs functions such as data configuration, alarm monitoring,

performance monitoring, and software upgrade. The M2000 supports both MML and

GUI modes.

5.3 Benefits

− The eNodeB provides configuration forms for the common configuration scenarios,

such as initial configuration, capacity expansion, and eNodeB replacement. In

addition, the eNodeB offers scenario-specific configuration wizards in GUI mode.

This scenario-oriented design helps to minimize the requirement for the user to

manually enter the configuration information, and speeds up the deployment.





25

− Huawei also provides the networking planning tool iPlan, which is used to import

data to the form for initial configuration, lowering efforts needed for network

planners and network optimization engineers.

High reliability

− The eNodeB provides data configuration, query, export, backup, and restoration

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

− Alarm handling suggestions are offered for every alarm, which helps the user to

locate and rectify the fault.

− For the localization methods, the alarm handling involves the related maintenance

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

5.3.5 Software Management

The software management of the eNodeB features easy accessibility, high efficiency, and little

impact on services during software upgrade.

Easy accessibility

− The user can perform health check on the eNodeB before and after an upgrade, back

up, download, and activate the software step by step by using the upgrade wizard of

the M2000. In addition, this function facilitates the user to query the upgrade status

and result.

− The eNodeB automatically upgrades the configuration data during upgrade.

Therefore, the user need not prepare the configuration data.





27

High efficiency

− The eNodeB supports remote upgrade and batch upgrade.

− The eNodeB supports upgrade strategy management. After the upgrade strategy is set,

the eNodeB can perform software upgrade automatically.

Small impact on services during software upgrade

− The eNodeB supports fast upgrade rollback. The user can perform version rollback

by running one command, reducing the impact of upgrade failures on the system.

− The eNodeB supports the management of patch packages. The eNodeB supports hot

patches, so that software corrections can be handled without interrupting system

operation.

5.3.6 Deployment Management

The eNodeB deployment solutions consist of automatic identification of the eNodeB and

initial configuration using a USB storage device. In addition, local commissioning is not

required. All these functions contribute to the ease of the deployment work and shortening of

work time. The field engineer needs only to install the hardware during site deployment. No

PC is required.

The automatic eNodeB identification function of GPS binding and unique ID binding is

supported.

The user can download the software and data of the eNodeB using a USB storage device,

saving a lot of time especially when the transmission bandwidth to the NE and the NMS

is limited.

Because local commissioning is not required, the software commissioning is performed

in the network management center instead of on site. The user can check and accept the

site deployment in the network management center.

5.3.7 Equipment Management

The eNodeB offers several user-friendly management functions.
