.3 G The Bss Software System, The Bsp Subsystem Design And Realization

Base Station System (BSS) undermentioned base on 3rd Generation mobile communications technologies (3G),it depend on Base Station Controller(BSS) and Base Station Transceiver(BTS) of CDMA,and BSS's plateform is Real-Time Operating System—VxWorks.BSS consists of many special modules,these modules achieved special functions and communicate by interface protocols.OSS is one subsystem of BSS,which include four modules:Board Support Package, Embedded Operating System,Running Support Package and peripheral cell.This paper takes example for Channel Processing module in BSS system to introduce the design and implementation of BSP.This paper anylize the component of BSS and where BSP location,according modularization,subdivide BSP into four modules:BOOT module,CPU subsystem module,Driver module and Board-Control module.Lastly,this paper execute verifying test and gave workable way for bugs during testing.This modularization design can make BSP subsystem become more repeatable and reliable, isolate Operating System from hardware effectively.
