  5. 5. eRAN2.1 DBS3900 LTE Product Description 1 DBS3900 LTE Overview Long Term Evolution (LTE) is the next step in 3G technology. LTE provides various technical benefits to Radio Access Network (RAN), such as flat network structure, reduced time delay, higher user data rates, improved spectral efficiency, optimized support for packet services, and improved system capacity and coverage. Compared with the 3G network, LTE has flexible bandwidth, enhanced modulation schemes, and effective scheduling, which meets the needs of operators. In addition, LTE allows operators to use both existing and new spectral resources to provide data and voice services.1.1 Positioning Focusing on the concept of customer-oriented innovation, Huawei launches the distributed E-UTRAN NodeB (eNodeB) DBS3900 LTE, one of the products in Huaweis SingleBTS product portfolio. The DBS3900 LTE fully exploits Huawei platform resources and uses a variety of technologies. The eNodeB represents the radio access equipment in the LTE system. Examples of radio access function the eNodeB performs are Radio Resource Management (RRM) functions such as air interface management, access control, mobility control, and UE resource allocation. Multiple eNodeBs constitute an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) system.

  6. 6. eRAN2.1 DBS3900 LTE Product Description Figure 1-1 shows the eNodeB position in the network. Figure 1-1 eNodeB in the network eNodeB: E-UTRAN NodeB E-UTRAN: Evolved Universal Terrestrial Radio Access Network EPC: Evolved Packet Core MME: Mobility Management Entity S-GW: Serving Gateway UE: User Equipment1.2 BenefitsAdvanced BS Platform, 2G and 3G Co-Network, RAN Sharing, and SmoothEvolution As LTE is one feature of SingleRAN,The DBS3900 LTE achieves smooth network upgrade by sharing the hardware platform and equipment of Huawei SingleBTS products with the DBS3900 GSM, DBS3900 UMTS, DBS3900 CDMA, or DBS3900 WiMAX. This saves the cost of LTE site deployment. The DBS3900 LTE can share the network with the 2G or 3G network, and supports handovers between the LTE and the PS domain of the GERAN/UTRAN/CDMA2000. This facilitates LTE network deployment in the existing 2G or 3G network. The DBS3900 LTE supports RAN sharing. Different operators can share the RAN network, thus reducing Capital Expenditure (CAPEX). The BBU3900 is the baseband unit of the DBS3900 LTE. The BBU3900 is hardware ready in terms of multi-mode applications. Therefore, boards of different modes installed in one BBU3900 are supported. The RRU is the remote radio unit of the DBS3900 LTE. The BBU3900 and RRU can be flexibly configured on the basis of capacity and coverage requirements. Using the approach of stack installation, capacity expansion can be easily achieved through board/module stacking, rather than equipment replacement. Therefore, the cost of hardware upgrade is significantly reduced. Huawei Proprietary and Confidential V2.0 (2011-01-20) Page 5 of 47 Copyright © Huawei Technologies Co., Ltd.
  7. 7. eRAN2.1 DBS3900 LTE Product DescriptionLarge Capacity, Extensive Coverage, and High Throughput The DBS3900 LTE provides large capacity, with a single eNodeB supporting a maximum of 3,600 users in connected state (RRC connected). The DBS3900 LTE provides extensive coverage. With features such as multi-antenna RX diversity and uplink Inter-cell Interference Coordination (ICIC), the DBS3900 LTE supports a maximum cell radius of 100 km. The DBS3900 LTE provides high throughput. With features such as 64QAM high-order modulation, uplink and downlink Multiple Input Multiple Output (MIMO), and ICIC, the DBS3900 LTE reaches the maximum throughput of 450 Mbit/s in the downlink and 300 Mbit/s in the uplink.Enhanced SON Function Automatic configuration: The DBS3900 LTE can automatically obtain connection parameters, download software, configure data, conduct tests, and upload information to the EMS. This requires less preparation for data configuration and reduces manual handling during site startup. Therefore, the OPEX can be minimized. Automatic Neighboring Relation (ANR): The DBS3900 LTE can automatically maintain the integrity and validity of the neighboring cell list by automatically detecting missing neighboring cells and evaluating the neighboring cell relationships. This increases the handover success rate 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, thus reducing the workload of manual network fault location.Comprehensive IP Transport A wide variety of transmission ports are supported, such as FE/GE electrical ports, FE/GE optical ports, and E1/T1 ports. All-IP transport is supported. In addition, diversified network topologies are supported, such as star, chain, and tree topologies. Multiple QoS mechanisms are adopted to guarantee the transmission QoS, thus providing highest capacity, implementing differentiated services, and meeting QoS requirements of services.Easy Installation and Low CAPEX for Operators The DBS3900 LTE is compact, light, and easy to transport, and it also supports distributed installation, thus reducing large scale construction engineering and saving the CAPEX. The BBU3900 can be installed on an indoor wall or in a standard cabinet. This reduces unnecessary installation investment. The RRU can be mounted to a pole, tower, or concrete wall. Flexible installation location and low space requirements reduce site lease costs. The RRU can be installed close to the antenna system in order to reduce the cost of feeders and power consumption.
