• Monitoring the RBS performance
The RBS also contains all the software necessary for Element Management.
3.2 Hardware
The RBS comprises of at least one cabinet with three subracks:
• Baseband (BB)
• Radio Frequency (RF)
• Multiple Carrier Power Amplifier (MCPA)
Apart from the subracks, the RBS consists of a capacitor unit (CU) and a
connection field.
3.3 Software
This section gives an overview of the software architecture and common
platform. For a detailed description, please refer to page 13.
Software Architecture
The RBS software architecture consists of two layers:
• The common platform layer provides basic support for the application
program and includes the operating system and provides support for
Asynchronous Transfer Mode (ATM) transport, as well as O&M.
• The application program layer runs on top of the common platform layer
and defines the RBS functionality.
A Main Processor (MP) and subordinate Board Processors execute the RBS
software.
Common Platform
The RBS software is based on a common platform used both in RBS and RNC.
From this platform it is possible to create an ATM cell-switching network node.
The common platform consists of an ATM transport system, a distributed
real-time telecommunication control system, and an element management
system built with Java technology. ATM is used for communication between
boards, subracks and nodes.
