Video and TELCO network control functionality

摘要

To efficiently provide a variety of different services, e.g. voice grade telephony, packet data services, and broadband services, through an integrated network, at least some routing functions relating to all of the different types of services are controlled by data stored in a single central controller. Nodes or switching points performing the routing functions for the different types of services recognize certain call processing events as triggers. In response to a trigger, such a switching point will suspend processing of the particular call and obtain routing instructions from the central controller as to how to complete call processing.
