Abstract

A communication system includes a switching system and a service control system. The switching system receives and processes a communication request to transfer a query message. The service control system receives and processes the query message to generate and transfer a response message indicating a route. The switching system receives and processes the response message indicating the route and transfers a communication using the route. The service control system may process the query message with multiple parallel functions to generate an action message and process the action message to select the route.

Claims (50)

1. A communication system comprising:

a first switching system configured to receive and process a first communication request for a first communication to determine if the first communication request indicates a first route, if the first communication request does not indicate the first route, to transfer a first query message, receive and process a first response message indicating the first route, and transfer the first communication using the first route, and if the first communication request does indicate the first route, then to transfer the first communication using the first route;

a service control system configured to receive and process the first query message to generate and transfer the first response message indicating the first route; and

wherein the first route identifies one of a downstream switch, network element, connection, switch/trunk, and packet address.
