AUTOMATED MASS CALLING DETECTION USING CCS7 MESSAGE PARAMETERS |
摘要 |
In a telephone network having a number of telephone switching offices which have CCS7 signalling capabilities and wherein each switching office is linked to STPs (Signalling Transfer Points), or other switching offices with CCS7 signalling links, a method of detecting mass calling events using CCS7 signalling data is disclosed. Each signalling link connecting a switch is monitored. For each call, an Initial Address Message sent from an originating switch to a terminating switch is identified. The IAM is then temporarily stored in storage means. When the occurrence of a release message indicative of an unsuccessful call attempt is detected, an identification of which of the stored IAMs corresponds to the release message is made. A count is computed for each directory (DN) having an IAM with a corresponding release message indicative of an unsuccessful call attempt such that mass calling events directed to a directory number can be detected.
