3 Principles and Functions of a BBU3900
A BBU3900 is a baseband processing unit. It processes the baseband signals of a base station.
Principle
The BBU3900 includes the baseband subsystem, cabinet subsystem, transmission subsystem, interconnection subsystem, main control subsystem, monitoring subsystem, and clock subsystem, and each subsystem consists of different units or modules as follows:
l The baseband subsystem consists of the baseband processing unit.
l The cabinet subsystem consists of the backplane, fan, and power modules.
l The transmission subsystem consists of the main control transmission unit and transmission extension unit.
l The interconnection subsystem consists of the main control transmission unita and infrastructure interconnection unit.
l The main control subsystem consists of the main control transmission unit.
l The monitoring subsystem consists of the power module and monitoring unit.
l The clock subsystem consists of the main control transmission unit and clock signal processing unit.
NOTE
a: The main control transmission unit in an interconnection subsystem is the UMPT.
The following figure shows the principle of the BBU3900.
Figure 3-1 Principle of the BBU3900
Function
The BBU3900 performs the following functions:
l Provides ports to be connected to the transmission equipment, RF modules, USB devicesa, external clock reference, and LMT or M2000 for transmitting signals,
automatically upgrading software, receiving clock reference, and maintaining the BBU on the LMT or M2000.
l Manages the entire base station system, including the processing of uplink and downlink data, signaling processing, resource management, and operation and maintenance.
NOTE
a: The security of the USB port is ensured by encryption, and the USB port can be shut down using commands. The USB commission port is used for commissioning the base station rather than configuring and exporting information of the base station.
