resources. A single RNC can handle one or more RBSs and an RNC can
work with other RNCs to increase capacity.
For detailed information about the RNC,
see Node Description, RNC 3810,
6/1551-AXD 10503/1.
• The RBS provides radio resources and handles radio transmission and
reception to and from the UE.
RANOS
RANOS is one of the network management systems the operator can use.
RANOS is used to handle O&M tasks such as alarm handling, configuration
and performance monitoring.
It is possible to integrate RAN with existing network management systems.
3 RBS Overview
The following section is a brief introduction to the RBS.
Common Platform
The RBS hardware and software are based on a common platform used both
in RBS and RNC. From this platform it is possible to create an Asynchronous
Transfer Mode (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.
Hardware
The RBS comprises one cabinet with a subrack for plug-in units. Other units
are a Climate Unit, a Fan Unit, a Capacitor Unit, a Connection Field and a
Power Distribution Unit.
Software
The RBS software architecture consists of two layers: the Common Platform
Layer and the Application Program Layer:
• The Common Platform Layer provides basic support for the application
program and includes the operating system and provides support for
ATM transport, and O&M.
• The application program 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.
