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 and

active/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.
