3.2.1 Logical Structure of the BBU3806The BBU3806 consists of the transport subsystem, baseband subsystem, control subsystem, andinterface module.

Figure 3-2 shows the logical structure of the BBU3806.

Figure 3-2 Logical structure of the BBU3806

Transport SubsystemThe transport subsystem performs the following functions:l Providing physical interfaces between the BBU3806 and the RNC for data communication

l Providing OM channels between the BBU3806 and the LMT or between the BBU3806 andthe M2000

Baseband SubsystemThe baseband subsystem processes uplink and downlink baseband data. The functions of thebaseband subsystem are performed by the following modules:l Uplink baseband data processing module: consists of the demodulation unit and the

decoding unit. In this module, uplink baseband data is processed into despreading softdecision symbols after access channel searching, access channel demodulation, anddedicated channel demodulation. The symbols are then sent to the RNC through thetransport subsystem after decoding and Frame Protocol (FP) processing.

l Downlink baseband data processing module: consists of the modulation unit and theencoding unit. The module receives the service data from the transport subsystem, andimplements FP processing, encoding, transport channel mapping, physical channelgenerating, framing, spreading, modulation, and power control combination. Then the datais finally sent to the interface module.

Control SubsystemThe control subsystem manages the entire distributed NodeB. The control subsystem performsOM, processes signaling, and provides the system clock.



3-3

l The OM module performs functions such as equipment management, configurationmanagement, alarm management, software management, and commissioning management.

l The signaling processor performs functions such as NBAP signaling processing, ALCAPprocessing, SCTP processing, and logical resource management.

l The clock module provides the system clock for the NodeB. The reference sources of thesystem clock are the Iub phase-lock line clock (obtained from the E1, optical port, or FE),the GPS clock, and the external clock (for instance, the BITS clock). The versions laterthan V100R009 support the function of extracting the clock from the FE.

Interface Module

The interface module performs the following functions:l Each CPRI port of the BBU3806 adopts the Enhanced Small Form-Factor Pluggable

(ESFP) optical ports, and transports the uplink and downlink baseband data of the RRU/pRRU3801/RHUB3808.

l Each BBU3806 provides an EIa port to share synchronization data, baseband data, powercontrol data, and transmission data between BBU3806s.

3.2.2 Logical Structure of the BBU3806CThe BBU3806C consists of the transport subsystem, baseband subsystem, control subsystem,and interface module.

Figure 3-3 shows the logical structure of the BBU3806C.

Figure 4-2 Star topology

Advantages:

l The NodeB is directly connected to the RNC. Therefore, the star topology featuressimplicity, convenience in maintenance, engineering, and capacity expansion.

l Direct data transmission is built between the NodeB and RNC and signals travel throughfewer nodes, which gives higher transmission reliability.

Disadvantage: Compared with other topologies, the star topology requires more transmissionresources.

4.1.2 Chain TopologyThe chain topology applies to the belt-shaped and sparsely populated areas, such as highwaysand railways.




4-3

Figure 4-3 Chain topology

Advantage: The chain topology can reduce costs in transmission equipment, engineering,construction, and transmission link lease.

Disadvantages:

l Signals travel through many nodes, so the transmission reliability is low.

l Faults in the upper-level NodeB may affect the lower-level NodeB(s).

l The number of levels in the chain topology cannot exceed five.

4.1.3 Tree TopologyThe tree topology applies to complicated networks and sites such as a large area withconcentrated hot spots.

5 Clock Synchronization Modes of theDBS3800

The DBS3800 supports five clock synchronization modes: line clock, GPS clock, BITS clock,IP clock, and internal clock.

Line ClockThe BBU directly extracts clock signals from the Iub interface such as the E1/FE interface. Then,the BBU outputs the precise 2.048 MHz and 8 kHz clocks after frequency dividing, phaselocking, and phase adjusting. The 2.048 MHz and 8 kHz clocks are used for framesynchronization and bit synchronization in the DBS3800.

NOTE

The BBU3806 V100R009 and later directly extracts the clock from the E1/FE port.The BBU3806 V100R008 and before can not directly extracts the clock from the FE port.

GPS ClockThe BBU provides the input port for the GPS clock and obtains the clock through the externalGPS device. This enables the BBU to receive GPS clock signals when the upper-level clock isunstable or unavailable.

BITS ClockThe BBU3806 supports the BITS clock mode by providing a port for the 2.048 MHz BITS clock.

NOTE

The BBU3806C does not support the BITS clock mode.

IP ClockWithout requirements for additional hardware, the IP clock is supported through softwareupgrade, providing IP transport with cost-effective clock solutions.

Internal ClockThe clock module of the BBU uses high-performance Oven Controlled Crystal Oscillator(OCXO) and adopts advanced algorithms and software phase lock technologies. The

performance of the BBU clock system reaches and exceeds the stratum-3 clock standard andcomplies with the related protocols in ITU-T G.812 and G.823. In the absence of external clocks,the internal clock can ensure that the NodeB works normally for at least 90 days and its precisioncan be higher than 0.05 ppm.

7.1 OM Modes of the DBS3800The DBS3800 supports local maintenance, remote maintenance, and reverse maintenance.

The OM subsystem provides the following three maintenance modes:

l Local maintenance: The NodeB is maintained on the Local Maintenance Terminal (LMT)through the local Ethernet port of the NodeB.

l Remote maintenance: The NodeB is maintained through the IP route provided by the RNC.The maintenance is performed on the M2000 client or the LMT in an Network ManagementSystem (NMS) center or an RNC equipment room.

l Reverse maintenance: Another NodeB is maintained on the LMT through the local Ethernetport of a local NodeB, and the IP route is provided by the RNC.

NOTE

The OM subsystem of the NodeB supports the automatic setup of default maintenance channel. Afterhardware installation, the NodeB can automatically set up a maintenance channel to the RNC on the ATMnetwork. Through this channel, the maintenance personnel can remotely download data and programs tothe NodeB, which enhances the network maintainability.

Figure 7-1 shows the OM subsystem of the NodeB.

Figure 7-1 OM subsystem of the NodeB

The OM subsystem of the NodeB consists of the following components:

l LMT: used to maintain single NodeB.

l M2000: used to maintain multiple NodeBs.

l OM channel: provides channels between the NodeB and the LMT and between the NodeBand the M2000.

l NE: refers to the maintained object.
