ZXSDR BS8906 Introduction
ZXSDR BS8906 (hereafter BS8906) is one of multi-carrier, multi-mode outdoor
micro base station in ZXSDR BTS series.
BS8906 accomplishes UE access and radio link transmission including RF
processing, channel coding and decoding, channel multiplexing and de-
multiplexing, measuring and reporting, power control, transmit diversity, receiving
diversity, calibration and synchronization.
BS8906 connects with BSC/RNC and accomplishes the following functions
including cell management, reporting BTS measurement information, broadcasting
system Information, implementing access control from BSC/RNC, mobility
management, radio resource management and controlling, FP processing and
ATM transmission management.
With operating and maintenance interface, BS8906 provides system management
functions including configuration management, alarm management, status
checking and system monitoring.

The operating support layer provides the functions of OSS, OAM, DBS, BRS, BRACS, and
SCS to serve to different BTS mode. OAM (Operating and Maintenance) is to provide the configuration, alarm and
performance measurement function.
DBS (Data Base Sub-system) is the database system.
BRS (Barrier Sub-system) is for protocol stack processing.
BRACS (Barrier Access Control Sub-system) is to control the access to bear layer.
SCS (System Control Sub-system) is to control the power supplying andactive/standby switching.
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. Detects the external and internal environment temperature in real
time.
BSP (Board Support Package) supports the information routing to the GSM and public
parts in the application layer.
VxWorks is the operation platform communication to the hardware components.

The BSS provides a transparent channel to implement operation and maintenance
information interaction between NetNumen M31 and the BTS. Management of the BSC and
the BTS adopts unified client interface for unified security management and operation log.
And it has a unified service management interface. NetNumen M31 also supports
CORBA/SNMP Itf-N interface to be integrated with third-part NMS.
Maintenance Functions
Version Management
With this function, users can check the versions of the software and hardware running at
the foreground. The background provides a software downloading system for software
upgrade at the foreground. Before downloading, warehousing processing is required, that is,
copying the version file to the server and registering to the server.

Maintenance FunctionsConfiguration Management
Configuration management implements equipment configuration and radio configuration.
Log Management
Any operation performed by an operator is recorded automatically by the system. Thus, the
operation maintenance personnel can query historical operation records in some special
cases (such as abnormal system operations).
Security Management
Security management is implemented through user management and user group
management. The user element includes the user name and password, as well as which
user groups the user belongs to. The user group element includes the user group name
and authority information.
Performance Management
Performance management is to measure, report and make statistics of the System
performances.
