1 Overview
In general, GSM/EDGE/UMTS system consists of Core Network (CN), Radio Network
Subsystem (GERAN/UTRAN) and Mobile Station/User Equipment (MS/UE).
GERAN/UTRAN includes 2 network elements, base station and BSC/RNC. The
conventional 2G/3G BTS connects to BSC/RNC or MS/UE via Abis/Iub or Um/Uu
interface respectively. The flowing figureErro! Fonte de referência não encontrada.
shows a conventional GSM/EDGE/UMTS network system.
Figure 1 Conventional GSM/EDGE/UMTS Network System
In the figure 1, GPRS/EDGE and UTRAN are two separated radio networks. When ZTE
2G/3G dual-mode base station is introduced, the 2G/3G radio networks will be converged
into one and this will decrease the network construction cost greatly. The GSM/UMTS
integrated network is shown in following Figure.

Application layer consists of RFS (Radio Frequency Sub-system) and OAM (Operating
and Maintenance) sub-systems. Its main function contains software downloading,
configuration, management, system maintenance and measurement.
OSS (Operation Support Sub-system) is the support layer in this entire framework, which
is a hardware irrespective platform for running software and provides basic functions like
scheduling, timer, memory management, communication, sequencing control, monitoring,
alarming and logging.
BSP (Board Support Package) supports the information routing to the GSM, UMTS and
public parts in the application layer.
VxWorks is the operation platform communication to the hardware components.
