Abstract

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.
