Problems solved by technology

[0011] Therefore, the disadvantages of the prior art are: 1. The implementation of the call gap mechanism is relatively complicated and requires the cooperation of multiple devices; 2. The standard for evaluating system overload is more dependent on experience and has a close relationship with the processing capacity of the device itself ;3. The reference data for evaluating the system load is not direct enough, and can only partially reflect the real situation of the system load

Embodiment Construction

[0039]The present invention is based on the utilization of system resources, that is, the occupancy rate of the processor CPU as a reference index and a control target, and designs and implements a simple load proportional integral differential (PID, Proportion Integral Differential) controller, and according to the PID controller The output results directly limit the user's call flow. The PID controller first reads the processor CPU load information of the service switching node, and automatically adjusts the load information; then obtains a call filtering ratio through the PID control operation, and reports the call filtering ratio to the service control switching The service control call processing unit in the node; finally, the service control call processing unit directly rejects the user call flow reported by the service switching node according to the call filtering ratio value, so as to prevent the system from overloading.

[0040] Now the present invention will be fur...

Abstract

The method includes following steps: 1) presets an up limit for the load of processor, and defines the control error for the load of processor; 2) the PID control operation is made for the control error in the control period to get ratio of filtering call; 3) the system directly refuses the reported call request in term of the ratio of filtering call. The system thereof consists of a call controlling and processing unit, an automatically adjusting unit, and a PID controller connected to the automatically adjusting unit and the call controlling and processing unit.

Description

technical field [0001] The invention relates to the technical field of system overload control, in particular to a control method and system for preventing load overload in a communication network. Background technique [0002] Like other systems, in the intelligent network system, in order to ensure the long-term stable operation of the system, especially under the condition of large traffic, overload control measures must be taken to achieve maximum performance under system overload conditions. Guaranteed to provide services to users. The following uses an intelligent service as an example for description. [0003] In the intelligent network, the service control point SCP is the core component of the intelligent network. Its main function is to start different service logics according to the call events reported by the service switching point SSP, and send call control instructions to the corresponding service switching point SSP according to the service logic. , so as t...
