METHOD OF CONTROLLING TRAFFIC IN A TELECOMMUNICATION NETWORK

摘要

A method of controlling a telecommunications network, which includes at least on e local exchange connected by routes to one or more parent trunk exchanges each being one of a plurality of tr unk exchanges interconnected by trunk routes, in which the method consists of applying focused overload control to at least one trunk exchange of the network when the Bids per Circuit per Hour (BCH) along a primary traffic route from a pa rent trunk exchange to the local exchange exceed a certain threshold and the magnitude of a decrease in the avera ge Answer Seizure Ration (ASR) on the trunk primary traffic route to the parent exchange over a measurement period exc eeds an other threshold. The focused overload controls are call gapping controls, and the measurement period is appro ximately five minutes.
