Externally controlled call processing system
First Claim
1. A system for external control of call processing on a call connection network comprisinga network controller that is connected to receive an external party control message regarding a call connection operation to be executed by and involving one or more line controllers each connected to said call connection network by a call connection interface, said network controller being programmed to respond to said external party control message to determine what first party steps need to be taken by said line controller or controllers to execute said call connection operation, to generate first party control messages to carry out said first party steps, and to send said first party control messages over a message transfer network via message transfer interfaces to one or more said line controllers, said message transfer network being the same as or different from said call connection network, andsaid one or more line controllers,each said line controller being connected to said message transfer network via one of said message transfer interfaces to receive said first party control messages,each said line controller being connected to said call connection network via said call connection interface permitting said line controller to participate in a call over said call connection network with another line controller or other terminal device connected to said call connection network.each said line controller being connected to said call connection network via a call control interface permitting said line controller to request said call connection network to execute said call connection operation,each said line controller being programmed to execute said first party control messages on behalf of itself on said call connection network in order to execute said call connection operation on said call connection network.

Abstract
A system for external control of call processing including a network controller that is connected to receive a third party control message regarding a call operation to be executed by one or more line controllers and is programmed to determine what first party steps need to be taken by the line controller or controllers to execute the call operation, to generate first party control messages to carry out the steps, and to send the first party control messages over a network via a message transfer interface to one or more line controllers, the line controllers being connected to the network via message transfer interfaces to receive the first party control messages and being programmed to execute the first party messages on the network.
