Introduction

1.1 Overview To keep abreast of rapidly advancing mobile communications technologies, mobile operators are continually seeking partners who provide cutting-edge technologies to set up high-quality, multimode-enabled, and future-oriented mobile networks efficiently and cost-effectively. With this aim in mind, Huawei developed 3900 series base stations, which are designed based on a high-performance platform and use an optimized hardware and software architecture. These base stations can work in multiple modes due to their cutting-edge modular design. They also have broad bandwidth and are eco-friendly and easily upgradeable. Specifically, 3900 series base stations use the newly developed power amplifiers (PAs), provide the temperature control function, and employ the innovated power saving technique. In addition, by adopting the cutting-edge modular design, 3900 series base stations use multimode modules with different appearances to meet requirements in various conditions. Thanks to all these merits of 3900 series base stations, mobile operators can set up highquality, multimode-enabled, and future-oriented mobile networks and capital expenditure (CAPEX) on site acquisition, capacity expansion, and environment protection can be greatly reduced. Different types of 3900 series base stations can be delivered on request because the newly designed modules and auxiliary devices can be flexibly combined and configured. Figure 1.1 shows the different types of 3900 series base stations.

1 Introduction

1.2 Benefits Smooth Evolution Upgrading from Global System for Mobile Communications (GSM) to Universal Mobile Telecommunications System (UMTS) and then to Long Term Evolution (LTE) is easy thanks to the following factors: 

In SRAN7.0 or earlier: A BBU3900 is equipped with different boards, among which some work in one mode and the others work in another mode. The BBU3900 can process services for both of these modes. With two BBUs, the triple-mode application can be achieved.



In SRAN8.0: The GSM, UMTS, and LTE modes share one BBU3900.



Developed with the Software-defined radio (SDR) technique, RF modules can work in GU, GL, or UL dual-mode. SDR RF modules and single-mode RF modules can be installed in the same cabinet to achieve multimode and multi-band applications.

Energy-Efficient and Eco-Friendly Thanks to their small size and modular design, PAs do not take up much space in the equipment room and power resources are saved with the new power-saving technique. The following measures also help save energy: 

RF channels are blocked and PA voltage is adjusted if the downlink load reaches a preset threshold.



The power supply unit (PSU) shuts down if the base station is provided with sufficient power.



The temperature control function controls board temperature, outdoor cabinets use a direct ventilation system, and RRUs adopt the natural heat dissipation mechanism.

Low CAPEX In terms of the CAPEX for devices 

3900 series base stations use one set of multimode devices to support multimode applications.



An external reference clock and transmission resources are shared across modes on a 3900 series base station, reducing the CAPEX for transmission resources and external clock sources.



Various types of radio frequency (RF) modules are introduced, for example, softwaredefined radio (SDR) RF modules supporting antenna-sharing, dual-transmitter RF modules supporting the multiple-input multiple-output (MIMO) technology, and singletransmitter RF modules with high power and large capacity.



The GU or GL refarming feature is introduced to facilitate the evolution from GSM to UMTS, and LTE and eventually to save the CAPEX for evolution.

In terms of operation and maintenance (O&M), different modes on a single 3900 series base station share the same auxiliary devices and are managed by the same network management system, which greatly reduces O&M costs. The O&M manpower required is also reduced, because 3900 series base stations are easy to install and maintain and it is easy to expand their capacities.

2.2 Basic Modules 3900 series base stations have a modular design. The basic modules are the baseband unit (BBU) and radio frequency module which includes radio frequency unit (RFU), remote radio unit (RRU), and active antenna system (AAS). The BBU uses common public radio interfaces (CPRIs) and electrical or optical cables to communicate with the RFUs or RRUs.

2.2.1 BBU The BBU (BBU3900 and BBU3910) is a baseband control unit and performs the following functions: 

Centrally manages the entire base station, including operation and maintenance, signaling processing, and the system clock.



Processes uplink and downlink baseband signals.



Provides physical ports, which are used to connect the base station to the transport network for information exchange; a maintenance channel, which is used to connect the BBU to the operation and maintenance center (OMC); CPRI ports for communication with RF modules; and ports for communication with environment monitoring devices.

Figure 1.1 shows the slot layout of a BBU. Figure 1.1 Slot layout of a BBU

For details about the BBU3900 and BBU3910, see the BBU3900 Description and BBU3910 Description, respectively.

2.2.2 RFU RFUs can be used in a macro base station. The RFU modulates and demodulates baseband and RF signals, processes data, amplifies power, and conducts VSWR detection. RFUs fall into the following three types: 

Multimode modules: MRFU, MRFUd, MRFUe



2.9 DBS3900 LampSite 2.9.1 Overview The LampSite solution provides indoor coverage to indoor areas with high traffic, such as office buildings, shopping malls, bars, hotels, and parking lots. In the LampSite solution, the base station comprises the baseband unit (BBU), pico remote radio unit (pRRU), and RRU HUB (RHUB). These modules can be flexibly combined to meet different scenario requirements. Like the DBS3900, the LampSite uses the same type of BBU. The RHUB3908 and pRRU3901 are compact and light, and therefore they can be installed anywhere indoors. The RHUB3908, which is 1 U in height, can be installed in a cabinet, rack, shelf, or on a wall. The pRRU3901 can be installed on a wall or ceiling. In office buildings, BBUs are installed in an equipment room, and RHUBs and pRRUs are installed in the office areas, as shown in Figure 1.1. Figure 1.1 Example of the LampSite

In SRAN9.0, if the customer requires the WLAN network deployment in addition to the UMTS/LTE network, pRRUs with Wi-Fi daughter cards can be purchased and connected to the WLAN network through GE ports on the pRRUs.

Table 1.4 lists the number of required Ethernet cables for the LampSite solution in different scenarios. In the UMTS mode, the WBBPf or UBBPd board can be used as the baseband processing board. In the LTE mode, the LBBPd or UBBPd board can be used as the baseband board. The UBBPd board is recommended. When the UBBP board is used as the baseband board, the board supports only single-mode networks, not multi-mode networks. In the preceding tables, combination indicates combination of pRRU cells.

One pRRU has three slots, in which RF daughter boards in different modes can be configured to achieve flexible multi-mode configurations. Table 1.4 lists the number of required Ethernet cables for the LampSite solution in different scenarios.

Logical Structure

From the perspective of logical structure, 3900 series base stations consist of control subsystem, transport subsystem, baseband subsystem, RF subsystem, clock subsystem, and power and environment monitoring subsystem. Figure 1.1 shows the logical structure of 3900 series base stations. Figure 1.1 Logical structure of 3900 series base stations



Issue 05 (2014-06-30)

Control subsystem (BTS CTL subsystem): controls and manages resources in a base station. It provides the management plane interface between the base station and the OMC, the control plane interface between the base station and other NEs, and the interface for controlling and negotiating common devices in a multimode base station.


49


1 Introduction



Transport subsystem (BTS TRP subsystem): forwards data between the transport network and the base station. It provides physical ports between the base station and the transport network and the user plane interface between the base station and other NEs.



Baseband subsystem (BTS BB subsystem): processes uplink and downlink baseband data.



RF subsystem (BTS RF subsystem): transmits and receives radio signals. It provides ports for data transmission between the antenna system and the base station.



Clock subsystem (BTS TAS subsystem): synchronizes the base station clock with external clock sources. It provides ports between the base station and external clock sources.



Power and environment monitoring subsystem (BTS MPE subsystem): provides power supply, dissipates heat, and monitors the environment for a base station. It provides ports between the base station and site devices.

Operation and Maintenance

4.1 Overview 3900 series base stations are managed by an O&M system using either MML commands or a graphical user interface (GUI). This system is hardware-independent and provides comprehensive functions to meet users' various O&M requirements.

4.2 O&M System Structure O&M systems for 3900 series base stations in SRAN7.0 and earlier manage separate-MPT base stations locally or remotely using the GBTS SMT, BSC LMT, NodeB LMT, eNodeB LMT, or U2000, as shown in Figure 1.1.

Issue 05 (2014-06-30)


51


1 Introduction

Figure 1.1 O&M system structure for separate-MPT base stations

For such base stations, the O&M system consists of the following: 

GBTS SMT: locally manages one GBTS. O&M personnel use network cables to connect the PC running the GBTS SMT to the O&M port of the GBTS that the GBTS SMT will manage.



BSC LMT: remotely manages multiple GBTSs. O&M personnel use the BSC LMT to remotely manage multiple GBTSs in a centralized manner.



NodeB LMT: manages one NodeB. O&M personnel can use network cables to connect the PC running the NodeB LMT to the O&M port of the NodeB that the NodeB LMT will manage. Alternatively, O&M personnel can remotely manage a NodeB through O&M channels by connecting the PC running the NodeB LMT to the NodeB.



eNodeB LMT: manages one eNodeB. O&M personnel can use network cables to connect the PC running the eNodeB LMT to the O&M port of the eNodeB that the eNodeB LMT will manage. Alternatively, O&M personnel can remotely manage an eNodeB through O&M channels by connecting the PC running the eNodeB LMT to the eNodeB.



U2000: Huawei central O&M system. It centrally manages multiple base stations, provides a data configuration device called Configuration Management Express (CME), and incorporates the alarm monitoring, performance monitoring, software update, and inventory device management functions.
