The WiMAX system consists of the mobile station/subscriber station (MS/SS), access service network (ASN), and connectivity service network (CSN). Figure 1-1 shows the position of the DBS3900 WiMAX in the WiMAX network. Figure 1-1 WiMAX network structure

Issue V3.0 (2009-09-30)


Page 5 of 48

DBS3900 WiMAX V300R002 Product Description l

The MS/SS is the subscriber terminal on the WiMAX network. With the MS/SS, the subscriber uses the services provided by the operator.

l

The ASN consists of the BTS (DBS3900 WiMAX) and ASN-GW, and provides wireless access services for the CSNs of various network service providers (NSPs). One ASN can be connected to multiple CSNs.

l

The CSN consists of the router, the authentication, authorization and accounting (AAA) agent/server, and the Internet gateway, and supports subscriber databases. In addition, it performs functions such as IP connection, mobility management, QoS management, and billing management.

1.2 Features The DBS3900 WiMAX uses advanced technologies, has high performance, and reduces the network construction cost.

Advanced BTS Platform Based on Huawei fourth-generation BTS platform, the DBS3900 WiMAX has the following features: l

Supporting smooth evolution from IEEE 802.16e to IEEE 802.16m and LTE/+TDD, and thus protecting the operator's investment

l

Supporting the all-IP network architecture so that the DBS3900 WiMAX can benefit from the high bandwidth and quick development of the IP network and effectively use abundant IP transmission resources

l

Supporting the multi-carrier technology (With software configuration, one sector supports multiple carriers to provide larger capacity. In this way, the number of new sites required for capacity expansion decreases, and the capacity expansion cost is cut down.)

l

Aiming at environment protection −

The DBS3900 WiMAX uses efficient power amplification technologies to reduce power consumption.

−

The RRU3702 works in natural cooling mode without any cooler and reduces power consumption.

−

With software configuration, the RRU3702 can be split into two 2T2R RRUs to cover two sectors. In this way, the number of required RRUs is reduced, and thus the BTS power consumption is reduced.

−

The DBS3900 WiMAX uses the multi-carrier technology, and thus two carriers share one RF channel. In this way, compared with two RF channels, the power consumption is reduced.

Wide Network Coverage With advanced technologies, the DBS3900 WiMAX has wide coverage to ensure high network performance. l

Supporting multi-antenna technologies −

Issue V3.0 (2009-09-30)

On the uplink, the DBS3900 WiMAX supports collaborate spatial multiplex (CSM) and maximum ratio combining (MRC) to obtain uplink gain, expand uplink coverage, and improve system capacity.


Page 6 of 48


−

On the downlink, the DBS3900 WiMAX supports two-antenna multiple input multiple output (MIMO) and four-antenna MIMO technologies such as MIMO A, MIMO B, MIMO A/MIMO B adaptive handovers, cyclic delay diversity (CDD), and Matrix A+CDD/Matrix B+CDD adaptive handovers. With multi-antenna technologies, the DBS3900 WiMAX obtains the downlink diversity gain and power gain to expand downlink coverage and improve system capacity.

l

Supporting the hybrid automatic repeat request (HARQ) technology (It is a technology integrating forward error correction (FEC) and automatic repeat request (ARQ) to improve transmission quality and to ensure that information is correct.)

l

Supporting outer-loop power control and closed-loop power control, which can minimize fading effect and interference to improve transmission quality

l

−

In outer-loop power control, the MS power can be timely adjusted according to the quality of downlink signals but the adjustment accuracy is not high.

−

In closed-loop power control, the MS power can be adjusted by step according to the quality of uplink signals, and thus the adjustment accuracy is high.

−

Outer-loop power control and closed-loop power control are dynamically switched. In this way, the MS power can be adjusted timely, and the power range can be accurately controlled.

Supporting adaptive modulation and coding (AMC), with which the system specifies appropriate modulation and coding modes according to channel quality −

When channel quality is good, the high-order modulation mode and high-rate coding mode are used to implement high transmission rate.

−

When channel quality is poor, low-order modulation mode and low-rate coding mode are used to ensure transmission link quality.

Easy Installation for Less CAPEX The DBS3900 WiMAX is compact and light, and supports multiple installation modes to reduce the footprint and the labor cost. l

The RRU is small and light (21 kg), and thus it can be installed on a pole, tower, wall, or support. In addition, the RRU can be installed near the antenna system to decrease feeder length and loss so that the feeder cost is reduced.

l

The BBU can be installed in the 19-inch cabinet such as the GSM cabinet or APM30H to avoid extra investment, as shown in Figure 1-2.

Issue V3.0 (2009-09-30)

Various Spectrum Applications The DBS3900 WiMAX supports the 2.3 GHz band (2.3 GHz to 2.4 GHz), 2.5 GHz band (2.496 GHz to 2.690 GHz), and 3.5 GHz band (3.4 GHz to 3.6 GHz). The DBS3900 WiMAX supports the following bandwidths: 5 MHz, 7 MHz (available only when the 3.5 GHz band is supported), and 10 MHz. Therefore, it satisfies the requirements of the operators having different frequency resources. In addition, various services can be provided through existing frequency resources and newly-added frequency resources.

WiMAX Network with High Security The DBS3900 WiMAX supports device authentication, subscriber authentication, message authentication, and air interface data encryption to improve network security. l

Device authentication and subscriber authentication can effectively prevent unauthorized devices and subscribers from accessing the WiMAX network and using resources and services on the WiMAX network.

l

Message authentication is implemented through the cipher-based message authentication code (CMAC) to ensure the validity of management messages and to prevent the messages from modification and forgery.

l

Air interface data encryption ensures the security of the data transmitted over the air interface and prevents subscriber data from interception and modification.

Flexible Networking The DBS3900 WiMAX supports four networking modes. The frequency reuse mode is denoted with N x S x K (N indicates the number of BTSs forming a cluster on the network, S indicates the number of sectors on each BTS, and K indicates the number of frequencies at which each BTS works). l

Issue V3.0 (2009-09-30)

PUSC 1x3x1: The three sectors of a BTS are used as a reuse cluster, each sector uses 1/3 subchannels at a frequency, and the equidirectional sectors on different BTSs use the same subchannel.


Page 8 of 48


PUSC with all SC 1x3x3: The three sectors of a BTS are used as a reuse cluster, the three sectors of each BTS work at a frequency respectively, and the equidirectional sectors on different BTSs work at the same frequency. Different BTSs use different UL_PermBase and DL_PermBase to balance interference, and thus the co-channel interference between cells is reduced.

l

FFR 1x3x1 (same-frequency FFR): The three sectors of a BTS are used as a reuse cluster and work at a frequency. In addition, the border area of each sector uses some subchannels to ensure coverage, and the center area of each sector uses all the subchannels to improve spectrum usage.

l

FFR 1x3x1 (different-frequency FFR): The three sectors of a BTS are used as a reuse cluster, each sector works at a frequency respectively, the border area of each sector uses some subchannels at the corresponding frequency, and the center area of each sector uses all the subchannels at the corresponding frequency.

Reliable Clock Synchronization As a synchronous communications system, the WiMAX system requires correct synchronization signals. The DBS3900 WiMAX obtains satellite synchronization signals in the following three ways: l

A GPS satellite card is integrated into the main control board and connects the satellite antenna and the device, and thus GPS satellite signals can be received.

l

When both GPS satellite signals and GLONASS satellite signals need to be received, the USCU must be installed. The GPS/GLONASS satellite card is integrated into the USCU and connects the satellite antenna and the device, and thus GPS satellite signals and GLONASS satellite signals can be received. The satellite card calculates and combines two types of signals to obtain more accurate signals. When satellite signals cannot be received, the system automatically switches to the free-run mode, and the BTS can work normally in this mode for eight hours.

Application Scenarios of the DBS3900 WiMAX

3.1 Overview The DBS3900 WiMAX is easily installed with a small footprint and has low power consumption. Therefore, it can coexist with the existing site. With these features, the DBS3900 WiMAX fully addresses operators' concern over site acquisition, facilitates network planning and optimization, reduces network construction time, and thus enables operators to efficiently deploy a high-performance WiMAX network with a low total cost of ownership (TCO) by minimizing the investment in electricity, space, and labor.

3.2 Application Scenarios This section describes application scenarios of the DBS3900 WiMAX.

BBU+RRU+APM30H There are two types of scenarios for BBU+RRU+APM30H: l

If the site is configured with the -48 V DC power supply and has no requirements for power backup, only the transmission cabinet TMC11H is used. The BBU and DCDU-03C are installed in the TMC11H, and the RRU is installed on the wall, pole, or tower. The DCDU-03C distributes the DC power supply to the BBU, RRU, and related transmission devices.

l

If the site is configured with only the 220 V AC power supply, the APM30H can be installed as required. The BBU and transmission devices are installed in the APM30H, and the RRU is installed on a wall, pole, or tower. −

If power backup is not required, only the outdoor power cabinet APM30H is used. It provides a maximum of 7U space for the installation of the customer's equipment.

−

When power backup is required, you can configure the battery cabinet IBBS200D or IBBS200T, each of which can be configured with a built-in -48 V 184 Ah storage battery group.

−

If larger space is required, you can configure the transmission cabinet TMC11H, which can provide extra 11U spaces.

Figure 3-1 shows the typical scenario of BBU+RRU+APM30H.

Co-Site Application If the DBS3900 WiMAX is installed at the same site with a 2G or 3G BTS, the BBU can be installed in a standard 19-inch cabinet that provides 2U space, and the RRU can be installed on the rooftop or the tower, and close to the antenna. In this scenario, the BBU and RRU can share the power backup system and transmission system with the 2G or 3G BTS, and thus network construction cost and period are reduced. Figure 3-3 shows the typical scenario of the co-site application. Figure 3-3 Typical scenario of the co-site application

Indoor Centralized Installation The DBS3900 WiMAX supports indoor installation, and the BBU and RRU can be easily installed on the L-shaped stand. In this case, the existing equipment room and devices can be shared, and thus the installation space is saved.

Operation and Maintenance

5.1 Overview The DBS3900 WiMAX supports two OM modes: centralized OM and local OM. l

Centralized OM: On the iManager M2000 in the equipment room, the user can remotely maintain BTSs in a centralized manner, such as data configuration, remote commissioning, alarm monitoring, performance monitoring, software upgrade, and network adjustment. This OM mode can save time and labor and thus reduce the operating expense (OPEX).

l

Local OM: With a computer, the user maintains the BTS by logging in to the BTS through the web site, such as alarm management, data configuration through man machine language (MML) commands, network adjustment, and subscriber management. The LMT software is not required for the computer.

Figure 5-1 shows the typical networking for OM. Figure 5-1 Typical networking for OM

Issue V3.0 (2009-09-30)


Page 28 of 48


5.2 OM Features The OM functions provided by the DBS3900 WiMAX involve software management, fault management, performance management, configuration management, site deployment management, equipment management, environment monitoring, tracing management, and log management.

Configuration Management Configuration management refers to configuring, querying, backing up, exporting, and recovering BTS configuration data. There are two modes of configuring DBS3900 WiMAX data: MML and graphic user interface (GUI). The MML mode is applicable only for single-BTS configuration. In the GUI mode, the user can use the WCS integrated into the M2000 client to configure BTSs in batches.

Fault Management The fault management system of the DBS3900 WiMAX detects hardware faults, environment faults, and transmission faults, isolates the faulty components, and reports alarms. The user can block the faulty carrier to prevent the neighboring cell from interference. Therefore, the impact of faulty cell on the other components of the BTS can be avoided, and the impact on the system services is minimized. The alarm management system of the DBS3900 WiMAX timely detects and reports the faults or exceptions on devices. On the iManager M2000, alarm information is displayed, and the suggestions for clearing alarms are provided.

Performance Management The performance management system of the DBS3900 WiMAX provides an all-around visual operating environment. The user can perform performance management on the devices of the entire network. Performance management refers to creating, modifying, and querying performance measurement tasks and to managing measurement results. The user can trace the running statuses of the network and devices, assess the performance of the network and devices, and obtain network optimization references through performance management. On the M2000, the user can set the subscription period and object. Then, performance measurement results are displayed on the client of the M2000 periodically. The subscription period can be set to 30 minutes.

Software Management The DBS3900 WiMAX provides software version query, software upgrade, and patch management. l

Software version query refers to querying the BTS software version through MML commands.

l

One-key software upgrade refers to upgrading the software of multiple BTSs through GUI upgrade wizard on the M2000 client, and involves performing the health checks before and after the upgrade, downloading and activating the software, displaying the upgrade progress and status during the upgrade, sending the upgrade report during the upgrade, and verifying services after the upgrade.

Issue V3.0 (2009-09-30)


Page 29 of 48


If the software upgrade fails or the network performance deteriorates greatly in the call test after the upgrade, the user can perform version rollback through the GUI upgrade wizard on the M2000 client to minimize the impact of upgrade failure on the system. l

Patch management involves patch query, patch installation, and rollback.

Site Deployment Management The site deployment solution provided by the DBS3900 WiMAX includes boards in cabinets transportation, automatic detection of the BTS, and local OM without software commissioning. All these functions greatly contribute to the reduction of the deployment difficulties and the shortening of work time. l

With the automatic detection of the BTS, the user imports the BTS ESN, IP address, and the relevant information to the DHCP server through the DHCP tool on the remote client of the M2000. Then, the DHCP server automatically allocates an IP address to the BTS according to the BTS ESN, and sets up the OM link between the BTS and the M2000.

l

The software commissioning is performed in the network management center rather than on site because the local commissioning is not required.

Environment Monitoring The DBS3900 WiMAX performs comprehensive environment monitoring functions through the environment monitoring device. Therefore, the unmanned DBS3900 WiMAX can be deployed across wide areas and operate adverse environments. The environment monitoring device is connected to the BBU3900 alarm port through the monitoring signal cable. When the environment monitoring device detects an alarm of access control, infrared sensing, smoke sensing, water sensing, or temperature monitoring, or a customized alarm, the BBU reports the alarm to the M2000 and informs the attendant.

Tracing Management Tracing management refers to tracing the R1 interface, R6 interface, subscribers, and system resources through the M2000. l

Interface tracing management refers to tracing and resolving the messages over the R1 and R6 interfaces, facilitating fault location.

l

Subscriber tracing management refers to tracing a single subscriber's messages over the R1 and R6 interfaces. In this way, the user can monitor the information such as signal quality.

l

System resource tracing refers to tracing carrier status, board CPU usage, and board temperatures. In this way, the user can learn about the usage of system resources.

Log Management Logs are classified into operation logs, running logs, security logs, commissioning logs, and call logs. The user can back up logs in a specified directory and at a specified interval.
