1 Introduction

1.1 3900 Series NodeBs

The mobile communications, which takes an ever-changing presence with each passing day, blazes a trail for the upgrade of technologies and products. The growing trend of mobile communications comprises a series of evolution, from GSM to EDGE to EDGE+ and from WCDMA to HSPA to HSPA+ and LTE, and it is worth mentioning that WiMAX also joins the 3G family. To follow the trend, the network operators have to devote more CAPEX and OPEX to the dramatic change of technologies, and therefore they are currently focusing on the merge of multiple network systems into a more cost-effective one.

Upon the transition of mobile networks, the network operators target at the Blue Ocean Strategy and invite innovative and responsive partners. Customer-oriented and innovative, Huawei advocates four basic technological concepts: green, merge, wideband, and evolution. Huawei will take the lead in developing the next-generation base stations and the 3900 series NodeBs, Huawei's fourth generation base stations, will outclass other base stations to benefit operators with future-oriented networks.

Huawei unveils cutting-edge techniques in the 3900 series NodeBs, such as wideband, multi-mode system, and modular design. The 3900 series NodeBs consist of only three basic functional modules, characterized by compact structure, high integration, low power consumption, and easy and quick deployment. Flexible combinations of functional modules and auxiliary devices encourage Huawei to diversify the products. More importantly, the modules for different modes of systems can be installed in one cabinet to work as a base station adapting to different scenarios. Huawei also actively introduces new frequency bands and technologies to well meet operators' requirement for a compact multi-mode mobile network system.

Figure 1-1 shows the basic functional modules and auxiliary devices of the 3900 series NodeBs.



Figure 1-1 Basic functional modules and auxiliary devices

1.2 Product Features � Adaptable to diversified radio environments

Different combinations of functional modules and auxiliary devices diversify the NodeB products. For example, there are macro NodeB, distributed NodeB, and mini compact NodeB, which operate in different scenarios to better meet different network deployment requirements.

The 3900 series NodeBs provide a platform for the Huawei wireless products. To be specific, the base stations of different network systems such as GSM, WCDMA, CDMA, and WiMAX can share the same cabinet or even share one functional module at the same frequency band (based on the SDR technology), which makes it easy for network operators to choose a site type.

� Greatly reduced Total Cost of Operation (TCO)

The 3900 series NodeBs have many advantages, such as flexible installation, easy site selection, cost-effective solution, and fast network construction. The baseband module (BBU3900) is only 19 inches wide and 2 U high, taking a very small indoor space or taking a place in an outdoor cabinet. The RF module (RRU3900) can be installed close to the antenna without taking any space of the equipment room.

The RRU3804 supports up to four carriers with an output power of 60 W, known as the highest output power of the RRU in the telecom industry. The outstanding performance ensures wide coverage and high throughput. When two carriers are configured for the RRU3804, the number of sites can be reduced by 40%.



The 3900 series NodeBs use the high-efficiency digital Power Amplifier (PA), which greatly reduces power consumption and helps build a green communication network. Compared with the traditional NodeB, the macro NodeB (BTS3900) has its power consumption reduced by 30%; compared with the traditional macro NodeB, the BTS3900A cabinet, which is in direct-ventilation, has its power consumption reduced by 40%.

Based on the IP switch and multi-carrier technologies, the 3900 series NodeBs support the bandwidth of over 100 Mbit/s, which keeps up with the fast growing mobile data services and provides users with higher data transmission rate.

� Smooth evolution to future radio network systems

The 3900 series NodeBs support smooth evolution to HSPA+ and Long Term Evolution (LTE), thus fully protecting the investment of network operators.

3 Products and Application Scenarios

3.1 Distributed NodeB—DBS3900

As demand for environmental protection as well as lease cost has increased, the site selection has become a bottleneck in network deployment. It is increasingly difficult to adopt 2G/3G co-siting or to select a new site.

The distributed NodeB (DBS3900) developed by Huawei features high integration, easy installation, and low power consumption. All these features can facilitate site reselection and 2G/3G co-siting. In addition, the WRRU can be installed close to the antenna. In this way, the feeder consumption is reduced and system coverage is improved.

3.1.1 Integrated Application

If only the AC power is available at a new outdoor 3G site and power backup device is required, the combination of DBS3900 and APM can function as an outdoor macro NodeB. Figure 3-1 shows the typical configuration of DBS3900 + APM.

This configuration has the following features:

� The BBU3900 and transmission equipment can be installed in the APM cabinet and the RRU can be installed close to the antenna.

� The APM provides installation space and outdoor protection for the BBU3900 and supplies –48 V DC power to the BBU3900 and the WRRU. In addition, the APM manages and monitors the batteries and provides surge protection for the batteries.

� 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 back period.



Figure 3-1 DBS3900 + APM

3.1.2 Embedded Application with Existing Site Equipment

For the 2G/3G co-siting scenario, the BBU3900 can be installed in a standard 19-inch-wide and 2-U-high cabinet, and the WRRU can be installed close to the antenna, as shown in Figure 3-2. The BBU3900 and the WRRU can share the power backup system, transmission system, and antenna system of the BTS in the 2G network. In this way, operators can launch 3G services on the existing 2G network at a very low cost.

Figure 3-2 Embedded application based on existing site equipment

3.1.3 Outdoor BBU Application

For the 2G/3G co-siting scenario, the BBU3900 can be installed in the outdoor mini cabinet to function as an outdoor BBU. The WRRU can be installed close to the antenna for easy and quick deployment, as shown in Figure 3-3.



Figure 3-3 Outdoor BBU application

3.2 Indoor Macro NodeB—BTS3900

Figure 3-6 Cabinet macro NodeB (2)

3.4 Outdoor Mini NodeB—BTS3900C

The BTS3900C applies to the new outdoor 3G site environments such as tunnels, hot spots, places without equipment rooms, and marginal networks.

The BTS3900C supports –48 V DC power and 220 V AC power. If –48 V DC power is used, the mini cabinet must be configured with a DC power distribution box, as shown in Figure 3-7. If 220 V AC power is used, the mini cabinet must be configured with an EPS30-4815A and an SPD (AC), as shown in Figure 3-8. The BTS3900C can be installed on the pole, against the wall, or on the ground. The stand or support of other types can be applied to the installation of the BTS3900C on the ground.

Figure 3-8 Outdoor mini NodeB with 220 V AC power



3.5 Multi-Mode Base Station

The 3900 series NodeBs feature a unified platform and a modular design. Therefore, co-siting of modules in GSM, UMTS, or LTE mode can be supported, the baseband processing units and RF modules can share the same hardware platform, and modules in different modes can be located in one cabinet to support multi-mode application. This helps implement smooth evolution from GSM to UMTS or LTE.

With baseband modules for different modes configured in one cabinet, the base station can support the GSM only mode, UMTS only mode, or GSM/UMTS dual mode. In addition, with the baseband modules for LTE mode configured in the future, the base station can support the GSM/UMTS/LTE multi-mode application.

With RF modules for different modes configured in one cabinet, the base station can support the GSM only mode, UMTS only mode, or GSM/UMTS dual mode.

The RF modules in UMTS mode are LTE-ready in hardware. Thus the base station can support UMTS/LTE dual-mode through software upgrade in the same frequency band.

Figure 3-9 and Figure 3-10 show the multi-mode base stations for indoor and outdoor application respectively.

� The 3900 series NodeBs that adopt the IP switch-based Huawei platform support the GU co-cabinet application, HSPA+, and smooth evolution to LTE.

� The 3900 series NodeBs introduce the module-sharing concept, that is, the distributed NodeB, cabinet macro NodeB, and compact mini NodeB share all baseband and RF modules. The three types of basic modules form different NodeB products that apply to different scenarios, thus lowering CAPEX and OPEX.

� The dual-star GE IP switch technology enables exchange of large amount of internal data and satisfies more data traffic needs for HSPA+ and LTE in the future.

� The hot-swappable BBU3900 provides eight slots for boards and supports smooth capacity expansion and evolution.

� The combination of the duplexer and Transceiver Unit (TRU) in the RF module enhances the integrity of RF parts and meets the future requirements of the minimized, high-efficiency, and low-cost NodeBs.

� A minimized NodeB cabinet is easy to carry and install, and the stacked NodeB cabinets take up a small footprint.

4.2 High Integrity and Large Capacity

The 3900 series NodeBs are highly integrated and large in capacity:

� The BBU3900 contains highly integrated chips and features large capacity. A single BBU3900 supports 24 cells, with 1,536 UL CEs and 1,536 DL CEs. It also supports HSDPA and HSUPA services.

� A single RRU3804 or WRFU supports the 4-carrier configuration. When the NodeB evolves from 1 x 1 to 1 x 4 or from 3 x 1 to 3 x 4, no extra RRU or WRFU is required.

4.3 High Performance

The high performance of the 3900 series NodeBs are described as follows:



� The 3900 series NodeBs feature high receiver sensitivity. The 2-way receiver sensitivity is higher than –129.3 dBm without the Tower Amplification (TMA).

� The WRFU supports 80 W output power and the RRU3804 supports 60 W output power, which means that the PAs of the 3900 series NodeBs increase to 40%.

� IP over E1, to fully utilize the E1 resources of the existing network and to offer a complete solution of IP transmission

� Fractional Point-to-Point Protocol (PPP)

� ATM and IP dual stack, to protect operators' early investment in ATM transmission

� Compression and 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 kbit/s 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 kbit/s 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 transmission enables real-time services to travel on electrical ports, such as E1/T1 ports, and non-real-time services to travel on Ethernet ports.



4.5 Multiple Clock and Synchronization Modes

The 3900 series NodeBs support multiple clock and synchronization modes to fulfill different clock networking requirements:

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

� The 3900 series NodeBs adopt the GPS to achieve clock synchronization.

� The external clock synchronization refers to the 2 MHz clock on the transmission equipment.

� Without additional hardware, the system supports the IP clock through software upgrade, which provides a high-performance and low-cost clock solution for the IP transmission.

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

4.6 HSDPA Services

The 3900 series NodeBs support HSDPA services in the following aspects:

The SASU applies to two scenarios, namely the antenna shared by 2G and 3G systems and the antenna shared by two 3G systems. The SASU that enables two different systems at the same band to share one antenna system is an important part of the same band antenna sharing solution. It can greatly reduce the cost and time of the 3G network construction.

The SASU supports 900 MHz and 2100 MHz 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.

6 Reliability

6.1 Overview

The 3900 series NodeBs introduce a fresh new NodeB system structure and provides a complete redundancy design. It also takes advantage of Huawei large-capacity ASIC chips to enhance the integrity of modules, reduce the number of parts, and greatly improve the reliability of the system.

6.2 System Reliability

The system reliability of the 3900 series NodeBs 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 NodeB all 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 NodeB can automatically switch to another CPRI link.

The key data such as software version and data configuration files in the NodeB supports redundancy.

Reliability Design

The NodeB can automatically self-detect and diagnose hardware failures and environment 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.



6.3 Hardware Reliability

Anti-Misinsertion Function of Boards

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

Overtemperature Protection

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

Power Supply Reliability

Power supply units of the 3900 series NodeBs are also reliable in the following aspects:

� The 3900 series NodeBs have wide-range voltage and surge protection functions.

� The 3900 series NodeBs provide power failure protection for programs and data.

� The boards protect power supply against overvoltage, overcurrent, and reverse connection of positive and negative poles.

� Hierarchical shutdown

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

Surge Protection Reliability

The 3900 series NodeBs 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.

6.4 Software Reliability

The software reliability includes the redundancy of key files and data, and the powerful error tolerance of software.

Software Redundancy

The 3900 series NodeBs 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 NodeBs.

� Redundancy of software versions

The 3900 series NodeBs provide separate redundancy for software versions including the BootROM software version to avoid version problems. If one version is faulty, the NodeB can switch to the backup version.

� Redundancy of data configuration files



The 3900 series NodeBs 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

When the software is faulty, it does not affect the entire NodeB because the system is capable of self-healing. The software error tolerance functions are as follows:

� Scheduled detection of key resources

The 3900 series NodeBs perform occupancy check on software resources. If resource hang-up occurs due to software faults, the NodeB can release the unavailable resources in time and export logs and alarms.

� Task monitoring

During the running of software, the 3900 series NodeBs monitor the internal errors of all software and some hardware faults, if any. The 3900 series NodeBs 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 3900 series NodeBs perform scheduled or event-triggered data consistency check and can restore the data consistency preferably or preferentially. Also, they generate related logs and alarms.

� Dongle

The 3900 series NodeBs can detect the irregular running status of the software and then automatically reset the system through the dongles at both software and hardware levels.
