2 Benefits of the NodeB

The NodeB has a cutting-edge modular design of multiple mode and forms, thus adaptive tovarious installation scenarios. This effectively addresses the requirements for integrateddevelopment of a multi-mode mobile network, the broadband solution, and green networkrollout, and enables the construction of a future-oriented network and smooth evolution to theLong Term Evolution (LTE).

Solution of Integrated Multiple Technologiesl With the unified platform, modular design, and flexible combination of the basic modules

and auxiliary devices, the NodeB can present in multiple forms.l With this solution, BBUs and RF modules of different modes (GSM/UMTS/LTE) can be

placed in one cabinet, and cabinets of different modes can be installed in stacking mode.l The UMTS RF module supports smooth evolution to the LTE from the perspective of

hardware and supports the UMTS/LTE dual-mode NodeB through software upgrade in thesame frequency band.

Broadband Solutionl The outstanding performance of the RRU3804 and WRFU ensures wide coverage, high

throughput, and reduced number of sites.– The RRU3804 and WRFU adopt a multi-carrier technology which features 20 MHz

bandwidth and 4-carrier configuration.– A single RRU3804 supports the 60 W output power at the antenna connector and a

single WRFU supports 80 W at the antenna connector.l The NodeB supports the High Speed Packet Access (HSPA) service in full rate mode.

– The HSPA service enjoys high bandwidth and short delay.

– The data rate of the HSPA service can peak 14.4 Mbit/s in the downlink.

– The data rate of the HSPA service can peak 5.76 Mbit/s over the Uu interface at thephysical layer in the uplink.

l The IP-based switch core of the NodeB allows operators to obtain higher bandwidth andhave easier ways in capacity expansion and network adjustment by utilizing the existingIP transmission resources, thereby curtailing the cost for network deployment.

NodeBProduct Description 2 Benefits of the NodeB


2-1

– The NodeB can provide the Fast Ethernet (FE) port at the 100 Mbit/s externally, andthe IP Radio Access Network (RAN) can reuse the existing IP transmission resourceson the Iub interface.

– Apart from being more cost-effective than the Asynchronous Transfer Mode (ATM)-based network, the IP-based network provides the multi-access mode and sufficienttransmission bandwidth to satisfy the data service with high data rate.

Construction of a Green Network

The compact and modular design, innovative PA, and power consumption management are thekeys to a green communication network that features energy conservation and requires lessequipment rooms.

l The RF modules of the NodeB adopt the advanced Digital Pre-Distortion (DPD) and A-Doherty technologies to raise the power amplification rate to 40%. Thus, the powerconsumption of the entire NodeB is lowered.

l The reduced power consumption of the cabinet macro NodeB not only avoids extraelectricity expense but also lessens the investment in power supply, backup batteries, airconditioners, and heat exchangers.

– As the most compact macro NodeB in the industry, the cabinet macro NodeB takes upa small footprint.

– The RF cabinet of the BTS3900A is of direct-ventilation design. In comparison withthe traditional macro NodeB, power consumption of the BTS3900A is lowered by 40%.

l The DBS3900 is characterized by separate baseband and RF modules and distributedinstallation, which facilitates transportation, configuration, and installation.

– The BBU3900 of the distributed NodeB is characterized by a small footprint, easyinstallation, and low power consumption. In addition, the BBU3900 can be placed inthe spare space of an existing site.

– The RRU, small and light, supports installation near the antenna, thus preventing feederloss. Working in natural heat dissipation mode, the RRU has no fans. The high reliabilityof the RRU reduces the routine maintenance cost.

l The NodeBs of all types can share the baseband modules, RF modules, and power systems,thereby saving the cost for spare parts and maintenance.

The earlier-mentioned features of the NodeB can fully address the concern over site acquisitionfor operators, expedite network rollout, decrease occupation of resources such as manpower,power supply, and space, and lower the Total Cost of Ownership (TCO).

Smooth Evolution to the Future-Oriented Radio Network

The unified modular design of the NodeB helps the evolution to the future-oriented radionetwork, transformation of global operators, and deployment of new radio technologies.

l The NodeB enables different-mode modules plugged in the same cabinet to supportdifferent modes or different-mode modules inserted into the same cabinet to support multi-mode application.

l The UMTS RF modules support HSPA+ in terms of hardware, which enables other modulesof the existing NodeB to be shared to the maximum limit and facilitates smooth evolutionto the LTE.

Transport Subsystem

The transport subsystem functions as follows:l Providing physical ports for data communication between the NodeB and the RNC

l Providing OM channels between the BBU3900 and the OMC (LMT or M2000) foroperation and maintenance

Baseband Subsystem

The baseband subsystem processes uplink and downlink baseband data. The functions of thebaseband subsystem are performed by the following modules:l Uplink baseband data processing module: Consists of the demodulation unit and the

decoding unit. In this module, uplink baseband data is processed into despreading softdecision symbols after access channel searching, access channel demodulation, anddedicated channel demodulation. The symbols are then sent to the RNC through thetransport subsystem after decoding and Frame Protocol (FP) processing.

l Downlink baseband data processing module: Consists of the modulation unit and the codingunit. The module receives the service data from the transport subsystem and sends theservice data to the FP processor for FP processing. The signals are finally sent to theinterface module after encoding, transport channel mapping, physical channel generating,framing, spreading, modulation, and power control combination.

In the baseband subsystem, the BBU3900 has an integrated CPRI interface module that connectsthe BBU3900 to the RRU.

Control Subsystem

The control subsystem manages the entire distributed NodeB. The subsystem performs OM,processes signaling, and provides the system clock.l The OM module has functions such as equipment management, configuration management,

alarm management, software management, and commissioning management.l The signaling processor has functions such as NodeB Application Part (NBAP) signaling

processing, Access Link Control Application Part (ALCAP) processing, Stream ControlTransmission Protocol (SCTP) processing, and logical resource management.

10 Reliability of the NodeB

The NodeB features a new system architecture and a complete redundancy design. In addition,the NodeB takes advantage of Huawei large-capacity ASIC chips to enhance the integrity ofmodules and reduce the number of parts, thus significantly improving the system reliability.

System ReliabilityThe NodeB has the reliability design such as the load-sharing and redundancy configuration,and adopts the optimized fault detection/isolation technology of boards and systems, thus greatlyimproving the reliability of the system.

Redundancy design

l The main control board, transmission board, power supply unit, and fan unit in the NodeBall support redundancy. The BBU supports load sharing.

l The CPRI port that connects the BBU and the RF modules supports the ring topology.When one CPRI link becomes faulty, the NodeB can automatically switch to another CPRIlink.

l The key data such as software versions and data configuration files in the NodeB supportsredundancy.

Reliability design

The NodeB can automatically self-detect and diagnose hardware failures and environmentproblems, and then report alarms. It also attempts to conduct self-healing to clear faults. If theself-healing fails, the fault is automatically isolated.

Hardware ReliabilityAnti-Misinsertion function of boards

When a board is wrongly inserted into the slot of another board, the mistaken board cannot beconnected to the backplane, and in this way, the equipment is free from damage.

Overtemperature protection

When the ambient temperature of the PA on the RF module is too high, the NodeB generatesovertemperature alarms and immediately shuts down the PA to prevent it from damage.

Power supply reliability

NodeBProduct Description 10 Reliability of the NodeB


10-1

l The NodeB has wide-range voltage and surge protection functions.

l The NodeB provides power failure protection for programs and data.

l The boards protect power supply against overvoltage, overcurrent, and reverse connectionof positive and negative poles.

l The hierarchical shutdown is supported. The outdoor NodeB performs shutdown for thePA based on the backup power capacity.

Surge protection design

The NodeB takes surge protection measures on AC/DC power sockets, input/output signal ports(E1 port, interconnection port, and Boolean alarm port), antenna connectors, and GPS ports.

Software ReliabilityThe software reliability is embodied in the redundancy of key files and data and the powerfulerror tolerance of software.

Software redundancy

The NodeB provides redundancy for key files and data, such as software versions and dataconfiguration files, to prevent them from damage and to ensure the normal running of the NodeB.

l Redundancy of software versions: The NodeB provides separate redundancy for softwareversions including the BootROM software version to avoid version problems. If one versionbecomes faulty, the NodeB can switch to the backup version.

l Redundancy of data configuration files: The NodeB provides separate redundancy for dataconfiguration files to avoid interrupting the running of the files. If the current file becomesfaulty, the NodeB can keep working properly with the backup file.

Error tolerance capability

When the software is faulty, it does not affect the entire NodeB because the system is capableof self-healing. The software error tolerance of the NodeB covers the following aspects:

l Scheduled detection of key resources: The NodeB performs occupancy check on softwareresources. If resource hang-up occurs due to software faults, the NodeB can release theunavailable resources in time and export logs and alarms.

l Task monitoring: During the running of software, the NodeB monitors the internal errorsof all software and some hardware faults, if any. The NodeB also has a monitoring processto monitor running status and report alarms when the system is faulty, and try to restorethe task by self-healing.

l Data consistency check: The NodeB performs scheduled or event-triggered dataconsistency check and can restore the data consistency preferably or preferentially. Also,it generates related logs and alarms.

l Dongle: The NodeB can detect the irregular running status of the software and thenautomatically reset the system through the dongles at both software and hardware levels.
