System and method for detecting and limiting line resource occupation by calling back

Abstract

A system and method for detecting and limiting line resource occupation by calling back. The system is composed of a plurality of signaling message detecting and processing units MPM connected to related seventh signaling links and an operational management center CSM. The MPM detects the flowing signalling messages, and acquires the related messages onto the CSM; the CSM discovers callback access numbers according to callback service characteristic, synchronizes a blacklist generated by callback numbers required to limit to each MPM; and then the MPM realizes the limitation processing of subsequence call according to black and white list and service regulation. The invention can be independently implemented without improving the existing network device, can simultaneously realize quick discovering and limitation of callback numbers on one system, and can avoid problems of other modes required for modifying the existing network device data, difficulty in discovering related numbers, complicated use and the like. The system provides convenient and effective approach for limiting abnormal callback services of telecom operator, and avoids invalidation occupation and service distribution.

Description

technical field [0001] The invention relates to a communication technology between mobile and fixed, especially a system and method for detecting and restricting line resources occupied by callback. Specifically, under the premise of not needing to modify the existing network equipment, the service of restricting abnormal number callback is implemented independently, so as to avoid invalid occupation of network resources. Background technique [0002] The callback service is similar to a three-way call, but the call is initiated by the callback device. First, the traffic originator (hereinafter referred to as the user) dials the access number of the callback device, and the callback device actively hangs up the connection after receiving the calling number of the user, or the calling user immediately hangs up (no charge is incurred because the caller did not answer the call). Call back to the user's phone as the operator within the set time. After the user picks up the phon...

AI Technical Summary

Problems solved by technology

This method not only needs to add the analysis and processing function of finding the callback device in the existing billing or signaling monitoring system, but also needs to change the blacklist of multiple switches in the network synchronously, which is difficult to implement, with a large manual workload and complicated operation.
