Method and telecommunications network for control of mass calling.

摘要

The method involves detecting mass calling exclusively in network exchanges to which a subscriber is connected. One of the exchanges detects mass calling to one of the subscribers connected to this exchange, with choking carried out of traffic to this subscriber. The existence of mass calling to a subscriber is signalled to predetermined other exchanges in the telecommunications network. In the predetermined other exchanges, the traffic conveyed to the subscriber is choked at a rate which is preset for the respective predetermined exchange. A subscriber value is determined for the exchange to which the subscriber is connected and comprises the ratio of calls successfully switched to the subscriber to the total number of attempted calls to this subscriber received at the exchange. The subscriber value is compared with a subscriber threshold value and mass calling of the subscriber is detected when the subscriber value becomes less than the subscriber threshold value.
