Method for controlling overload of distributed processors of full electronic switching system

摘要

A method for controlling an overload of distributed processors of a full electronic switching system, capable of automatically calculating the number of calls to be accepted for a current interval by use of the number of calls accepted for a previous interval and the number of standby processes of a call processing program so that only the number of calls corresponding to the number of services calculated is acceptable, thereby maintaining a stable service condition for an overload control interval, and capable of realizing a priority control depending on the type of call. The method includes the first step of executing a call processing delay monitoring process loaded in an access switching processor by a priority not higher than a call processing process, but higher than an operation and maintenance process, thereby monitoring an execution condition of the call processing process, the second step of executing an overload control process by a priority higher than the call processing process, thereby determining and controlling an overload occurring in the processor, and the third step of repeating a process for changing a CPU reference value infinite times when a demand for a change of the CPU reference value is generated from an operator after the call processing delay monitoring process and the overload control process have started.
