Abstract

본 발명은 지능망(intelliegent network)이 하나 또는 소수의 집중화된 서비스 제어 시스템(Swervice Control Point; 이하, “SCP”라 한다)과 분산된 다수의 서비스 수행 교환기(Service Switching Point; 이하 “SSP”라 한다)로 구성된 경우 SCP를 과부하로 부터 보호하기 위한 지능망에서의 과부하 제어방법에 관한 것으로, 지능망에서 SCP가 과부하시 SCP의 정상 처리능력을 유지시킴과 동시에 지연시간등과 같은 서비스 품질을 만족시키는 효과가 있으므로 지능망 운용중 과부하시 지능망을 안정적으로 운용할 수 있을 뿐만 아니라 지능망의 수율을 향상 시킬 수 있는 효과가 있다.In the present invention, an intelligent network is referred to as one or a few centralized Service Control Points (SCPs) and a plurality of distributed Service Switching Points (SSPs). ), It is related to the overload control method in the intelligent network to protect the SCP from overload.In the intelligent network, the SCP maintains the normal processing capacity when the SCP is overloaded, and at the same time, satisfies the service quality such as delay time. Therefore, it can not only stably operate the intelligent network when overloaded, but also improve the yield of the intelligent network.

An overload control method applied to a first step, comprising: a first step of detecting whether an overload condition is started by increasing traffic of an intelligent network call and comparing a size of a SCP input buffer with a reference value; During the initial overload condition, a second step in which the overload control is performed in the SCP during the delay time from when the SCP detects the overload condition to the overload control in the SSP until the intelligent network call is reduced; The SCP predicts the number of calls attempted to each SSP during the current control interval, adds up all of them to the number of intelligent network calls attempted on the SCP, and compares the number of calls attempted to the SCP during the current control interval with the SCP throughput to determine if the overload is over. Third step of diagnosis; A fourth step of adjusting the intelligent network call attempted from the subscriber based on the control variable value, when the SCP calculates the value of the overload control variable and transmits the value to the SSP in a control message; A fifth step of repeating until the overload condition ends; Overload control method in an intelligent network comprising a. 제 1 항에 있어서, 상기 제 2 단계는, 정보 전송 요구 메시지 수신시 SCP 입력버퍼의 크기가 기준치 보다 작은가를 조사하는 단계 ; 기준치보다 작으면 정보 전송 요구 메시지 입력버퍼에 저정하고 종료하며, 적지않으면 정보 전송 요구 메시지를 기각하고 종료하는 단계를 포함하고 있는 것을 특징으로 하는 지능망에서의 과부하 제어방법.The method of claim 1, wherein the second step comprises: checking whether the size of the SCP input buffer is smaller than a reference value when receiving an information transmission request message; And storing the information transmission request message input buffer when the value is smaller than the reference value, and ending and rejecting the information transmission request message. 제 1 항에 있어서, 상기 제 5 단계는, SCP 내부 프로세서에게 다음 제어구간에 적용할 제어 변수값을 현재 제어구간에 적용된 제어 변수값과 현재 제어구간 동안에 SCP에 도착한 총 호의 갯수를 곱한 값을 단위시간당 SCP 처리능력과 제어구간의 길이를 곱한 값으로 나눔으로 산출하도록 한 것을 특징으로 하는 지능망에서의 과부하 제어방법.The method as claimed in claim 1, wherein the fifth step includes a control variable value to be applied to the next control section to the SCP internal processor by multiplying the control variable value applied to the current control section by the total number of calls arriving at the SCP during the current control section.
