Abstract: PURPOSE: A Method for collecting process load data in mobile communication system is provided to access an operating processor load data, so as to operate the system in stable condition. CONSTITUTION: A BSC(Base Station Controller) PLD(Processor Loaded Data) memory is composed of CCP(Call Control Processor) PLD and one of BCP(Base transmission station Control Processor) PLD. Each PLD's starting address is different for each system and the difference is because of the OS(Operating System) difference of each system. A process or a function that can access the PLD loaded in each BSC is implemented to be associated with BSM(Base Station Manager) and each BSC. The process communicates between BSM and BSC and directly accesses the BSC PLD memory. The accurate memory location is predefined when the BSC system is implemented in accordance with each CCP PLD and BCP PLD. The BSM accesses the PLD memory of BSC directly so the PLD data operated in the system can be accessed so that the operator can operate the system in stable condition. So the processor load data, which an operator requested is accessed, reported, and modified through the communication between a base station and a base station administrator.
