Page 6 Total 73


Figure 1-2 Deployment scenarios

Different combinations of the units and auxiliary devices form the following Horizon3G-nx Node Bs:

Macro Cabinet Node B

The macro Node B, integrates the BBU and the WRFU to form the Horizon 3G-nx macro Indoor and the Horizon 3G-nx macro Outdoor. The macro Node Bs are suited to centralized installation, where the Horizon 3G-nx macro Indoor and the Horizon 3G-nx macro Outdoor, are designed for indoor application and outdoor application respectively.

Distributed Node B

Page 7 Total 73


The distributed Node B, known as the Horizon 3G-nx fiber, consists of the BBU and the RRU. For distributed deployments, the RRU is placed close to the antenna. This reduces feeder loss and improves Node B performance.

Mini Node B

The Horizon 3G-nx mini can be deployed in both indoor and outdoor environments. It can be installed on a pole, wall, or ground. When installed on the ground, a stand or other support is required.

BenefitsThe Horizon 3G-nx Node B uses a uniform modular design, which minimizes the costs of network deployment and operations, such as site acquisition, capacity and coverage expansion and environment protection.

Fast Network Deployment and Efficient Site UtilizationThe Horizon 3G-nx Node Bs support both centralized and distributed installations, which simplifies network deployment and facilitates cost-effective network construction in a variety of scenarios.

The BBU can be installed in a 2U-high and 19-inch-wide indoor space or a protective outdoor cabinet while the RRU can be installed close to the antenna and has no footprint.

The cabinet macro Node B with its small footprint is one of the most compact Node Bs on the market.

Cost-Effective Capacity and Coverage SolutionThe 4-carrier Horizon 3G-nx fiber RRU generates up to 60 W of transmit power. This performance ensures wider coverage, higher throughput and fewer sites.

The Horizon 3G-nx fiber RRU can be mounted close to the antenna, connecting with the BBU through optical cables, thus avoiding feeder loss. Meaning that for the same power and system capacity, lower feeder loss delivers wider coverage or fewer sites under the same area.

Construction of a Green Communication NetworkCompact and modular design, innovative PA and power consumption management are the keys to an ecologically friendly communication networks that are relatively economic to run and require less equipment room space.

The RF units of the Horizon 3G-nx Node Bs use Digital Pre-Distortion (DPD) and A-Doherty technologies to raise the PA efficiency to around 40%. Thus, the overall power consumption of the Node B is lowered.

The RF cabinet of the Horizon 3G-nx macro Outdoor is a direct-ventilation cabinet. In comparison to the traditional macro Node B, equipment power consumption is reduced by around 40%.

The reduced power consumption not only avoids extra electricity expense but also lessens the investment in power supply, backup batteries, air conditioner and heat exchanger equipment.

Minimized Operation CostThe baseband units, RF units and power systems of the Horizon 3G-nx macro Indoor and Horizon 3G-nx fiber fit all Node B site types, thereby saving the logistics cost during manufacture, transportation and future maintenance cost (spares holding). The Horizon 3G-nx Node Bs are characterized by separate baseband and RF units, compact design and distributed installation. All these features facilitate the transportation and installation and make network construction less complicated and less expensive.

The RRU has no fans and is highly reliability, reducing routine maintenance cost.

2 SystemArchitecture

IntroductionThe Horizon 3G-nx Node Bs feature a modular design with the baseband processing unit BBU and the RF unit (RRU and WRFU) connected through the Common Public Radio Interface (CPRI).

The Horizon 3G-nx Node Bs comprises of three basic units, the baseband processing unit BBU, the indoor RF unit WRFU and the outdoor RRU. Auxiliary devices for the Horizon 3G-nx Node Bs include the APM, indoor macro cabinet, outdoor RF cabinet and outdoor mini cabinet. Flexible combinations of the three units and auxiliary devices provide comprehensive Node B site solutions for different scenarios.

BBU

Physical Structure of the BBUThe BBU, is 19 inches 2U high unit. It can be installed in an indoor 19-inch frame or an outdoor protective cabinet. Figure 2-1 shows the physical structure of the BBU.

Figure 2-1 Physical structure of the BBU

Page 10 Total 73


The 2-U-high space of the BBU integrates the functions such as main control, baseband processing and transmission. The BBU supports multiple configurations, from 1s1c to 6s4c or 3s8c.

Logical Structure of the BBUThe BBU is modular in design and based on the function of each module, can be split into the following subsystems:

Transport subsystem

Baseband subsystem

Control subsystem

Power monitoring module

Figure 2-2 shows the logical structure of the BBU.

Figure 2-2 Logical structure of the BBU

Transport Subsystem

The transport subsystem provides ports to exchange information between the BBUand the Radio Network Controller (RNC) – the Horizon 3G RAN controller.

In addition, the transport subsystem provides maintenance channels between the BBU and the Operation and Maintenance Centre (OMC), that is, the Local Maintenance Terminal (LMT) or Horizon OMC for BBU Operation and Maintenance(O&M).

Baseband Subsystem

The baseband subsystem processes both Uplink (UL) and Downlink (DL) baseband signals. The functions of the subsystem are performed by the following modules:

UL baseband signal processing module

Page 11 Total 73


− The UL baseband signal processing module consists of the demodulation unit and the decoding unit. In this module, uplink baseband signals are processed into de-spreading soft decision symbols after access channel searching, access channel demodulation and dedicated channel demodulation. The signals are then sent to the RNC through the transport subsystem after decoding and FP processing.

DL baseband signal processing module

− The DL baseband signal processing module consists of the modulation unit and the coding unit. Before sending signals received from the transport subsystem to the optical module, the module sends service data received from the transport subsystem to the Frame Protocol (FP) processor. After FP processing, the module processes the signals through transmission channel mapping, physical channel generating, framing, spreading, demodulating, transmit diversity control and power control combination. The module then sends the processed signals to the interface module.

The CPRI module is integrated in the baseband subsystem of the BBU.

Control Subsystem

The control subsystem manages the entire distributed Node B. The subsystem performs O&M, processes signaling and provides system clocks.

The O&M module performs functions such as equipment management, configuration management, alarm management, software management and commissioning management.

The signaling processor performs functions such as the Node B Application Part(NBAP) signaling processing, the Access Link Control Application Part (ALCAP) processing, the Stream Control Transmission Protocol (SCTP) processing and the logical resource management.

The clock sources of the Node B consist of the phase-locked line clock extracted from the Iub interface, the Global Positioning System (GPS) clock and the external clock such as the Building Integrated Timing Supply (BITS) clock. The BBU extracts the clock from the Iub interface and provides the clock signal for the entire Node B after frequency dividing, phase locking and phase adjustment in the clock module.

Power Monitoring Module

The power monitoring module converts –48 V DC power to suitable power for the boards. In addition, it provides the monitoring signal input port.

Scenarios

Distributed NodeB: Horizon 3G-nx fiberThe Horizon 3G-nx fiber typifies the compact design, easy installation and low power consumption required for a Node B, allowing it to be located within existing 2G site space. The RRU has a compact design and is light weight. It can be installed close to the antenna to decrease cable loss and improve system coverage. This enables service providers to efficiently deploy a high-performance network with a low Total Cost of Ownership (TCO) as less manpower, electric power and space are required during network build out.

Integrated Applications (BBU + RRU + APM)If only AC power is available at a newly built 3G site and power backup is required, the configuration of BBU + RRU + APM can be applied to perform the function of the outdoor macro Node B. Figure 3-1 shows the typical configuration of BBU + RRU + APM. This configuration has the following features:

The BBU can be placed in the APM and the RRU can be installed on the pole, close to the antenna

Extra space is reserved in the APM for the BBU installation. In addition, the APM provides functions such as battery power backup, AC/DC conversion, power distribution and surge protection

The APM30 can be configured with 12 Ah, 24 Ah, or 36 Ah built-in batteries and the APM100 can be configured with 50 Ah or 100 Ah built-in batteries. Whether the APM30 or the APM100 should be used depends on the required power backup period

Advanced Platform StructureThe advanced platform structure of the Horizon 3G-nx Node Bs is described as follows:

The Horizon 3G-nx Node Bs maximize on the FRU-sharing concept, that is, the distributed Node B, cabinet macro Node B and compact mini Node B all share the same baseband and RF modules. The three module types form different Node B products and apply to different scenarios. This concept protects investment in equipment and simplifies maintenance aspects, making the total cost of ownership very favorable.

The dual-star GE IP switch technology enables exchange of large amount of internal data and satisfies the increased data traffic needs of HSPA+.

The hot-swappable BBU provides eight slots and supports the ability to increase capacity and expansion as required.

The combination of duplexer and TRU in the RF module enhances the integrity of RF parts and meets the future requirements of the minimized, high-efficiency and low-cost Node Bs.

A minimized Node B cabinet is easy to carry and install and the stacked Node Bcabinets take up reduced footprint.

High Integrity and Large CapacityThe Horizon 3G-nx Node Bs are highly integrated and offer large capacity:

The BBU contains highly integrated chips and features large capacity. A single BBU supports 24 cells, with 1,536 UL CEs and 1,536 DL CEs. It also supports HSDPA, HSUPA and HSPA+ services.

A single Horizon 3G-nx fiber RRU (60W) or WRFU (80W) can support up to4-carriers. When the Node B evolves from 1s1c to 1s4c or from 3s1c to 3s4c, no extra RRU or WRFU is required.

Page 40 Total 73

Fractional Point-to-Point Protocol (PPP)

ATM and IP dual stack, to protect service providers' early investment in ATMtransmission

Compression multiplexing technology, namely the multiplexing of PPP header compression, PPPMUX and IPHC, to raise the transmission rate over E1 ports. With the technology of IPHC + PPP compression + PPPMUX, the E1 transmission rate of the 12.2 kbps voice service rises by up to 37%

FP Multiplex (MUX), to reduce the number of Medium Access Control (MAC) headers by multiplexing packets and to raise the transmission rate over FE ports. With this technology, the FE transmission rate of the 12.2 kbps voice service rises by up to 40%

Hybrid transmission, which enables services to meet different QoS requirements and then to allocate different transmission paths. For example, hybrid

Page 41 Total 73


transmission enables real-time services to travel on electrical ports, such asE1/T1 ports and non-real-time services to travel on Ethernet ports

Multiple Clock and Synchronization ModesThe Horizon 3G-nx Node Bs support multiple clock and synchronization modes to fulfill different clock networking requirements:

The upper-level clock extracts clock from the Iub interface and is set by default.

The Horizon 3G-nx Node Bs use GPS to achieve clock synchronization.

The external clock synchronization refers to the Building Integrated TimingSupply System (BITS) clock and the 2MHz clock on the transmission equipment.

Without additional hardware, software upgrade supports the IP clock. The IPtransmission provides a high-performance and cost effective clock solution.

The internal clock, an internal stratum-3 clock, ensures that the Node B without an external clock still works properly for at least 90 days.

HSDPA ServicesThe Horizon 3G-nx Node Bs support HSDPA services in the following aspects:

One carrier supports both HSDPA and R99/R4 services.

The peak downlink rate of a single UE is up to 21 Mbps (with 64QAM) and28Mbps (with 2 x 2 MIMO).

The SASU that enables two different systems on the same band to share one antenna system is an important part of the same band antenna sharing solution. It can reduce the cost and time of the 3G network roll-out.

The SASU supports 900MHz and 2,100MHz frequency bands.

The SASA is also an important part of the same band antenna sharing solution. It will cause an insertion loss of 0.8 dB in the downlink, but it can integrate transmit carriers from two antennas into one antenna, without affecting GSM network performance.

O&M PlatformsThe Horizon 3G-nx Node Bs support two O&M platforms, namely the LMT and the Horizon OMC and via which the Horizon 3G-nx Node Bs perform the following O&M functions:

6 Reliabili

ty

OverviewThe Horizon 3G-nx Node Bs introduce a new system structure and provide a complete redundancy design. It also takes advantage of large-capacity ASIC chips to enhance the integrity of modules, reduce the number of parts and greatly improve the reliability of the system.

System ReliabilityThe system reliability of the Horizon 3G-nx Node Bs is embodied in the load-sharing and redundancy configuration design, which optimizes the fault detection/isolation technology of boards and systems and greatly improves the reliability of the system.

Redundancy Design

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

The CPRI port that connects the BBU and the RRU supports ring networking. When one CPRI link is faulty, the Node B can automatically switch to another CPRI link. The key data such as software version and data configuration files in the Node B supports redundancy.

Reliability Design

The Node B can automatically self-detect and diagnose hardware failure and environment related problems and then report alarms. It also attempts to conduct self-healing to clear faults. If the self-healing fails, it can automatically isolate the faults.

Page 50 Total 73

Hardware Reliability


Board Insertion Failsafe

The backplane and boards have been designed to ensure that when a board is wrongly inserted into a slot [of another board], the board does not connect to the backplane and as a result damage does not occur.

Over Temperature Protection

When the ambient temperature of the power amplifier on the RRU is too high, the Node B generates over temperature alarms and immediately switches off the power amplifier to prevent it from damage.

Power Supply Reliability

Power supply units of the Horizon 3G-nx Node Bs are also reliable in the following aspects:

The Horizon 3G-nx Node Bs has wide-range voltage and surge protection functions.

The Horizon 3G-nx Node Bs provides power failure protection for programs and data.

The boards protect power supply against over-voltage, over-current and reverse connection of positive and negative poles.

Hierarchical shutdown

The outdoor Node B performs shutdown for the PA according to the backup power capacity.

Surge Protection Reliability

The Horizon 3G-nx Node Bs take 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 ReliabilitySoftware reliability includes the redundancy of key files and data and the powerful error tolerance of software.

Software Redundancy

The Horizon 3G-nx Node Bs provide redundancy for key files and data such as software versions and data configuration files to prevent them from damage and to ensure the normal running of the Node Bs.

Redundancy of software versions

The Horizon 3G-nx Node Bs provide separate redundancy for software versions including the BootROM software version to avoid version problems. If one version is faulty, the Node B can switch to the backup version.

Redundancy of data configuration files

Page 51 Total 73


The Horizon 3G-nx Node Bs provide separate redundancy for data configuration files to avoid interrupting the running of the files. If the current file is faulty, the backup file can still work properly.

Error Tolerance

Should a software fault develop, it does not affect the entire Node B because the system is capable of self-healing. The software error tolerance functions are as follows:

Scheduled detection of key resources

The Horizon 3G-nx Node Bs perform occupancy check on software resources. If a resource hang-up occurs due to software faults, the Node B can release the unavailable resources in time and export logs and alarms.

Task monitoring

During the running of software, the Horizon 3G-nx Node Bs monitor the internal errors of all software and some hardware faults, if any. The Horizon 3G-nx Node Bs also monitor task progress and running status, report alarms when the system is faulty and try to restore the task by self-healing.

Data Consistency Check

The Horizon 3G-nx Node Bs perform scheduled or event-triggered data consistency checks and can restore the data consistency preferably or preferentially. Additionally the Node Bs generate related logs and alarms.

Dongle

The Horizon 3G-nx Node Bs can detect the irregular running status of the software and then automatically reset the system through the dongles at both software and hardware levels.
