Abstract

An improved system for effecting broadband/multimedia calls and connections within an intelligent switched telecommunication network. This system, which employs object-oriented commands, is capable of establishing complex call and connection configurations between multiple network subscribers participating in a broadband/multimedia call. These object-oriented commands, which are stored in and initiated from network adjuncts or service control points, eliminate the need for long series of individual low-level commands to be transmitted to the network switching system. Furthermore, the system provides for a finite set of object-oriented commands which are capable of implementing the many complex and diverse interconnections which may be required in effecting multi-party broadband/multimedia calls. This is accomplished by selectively combining various object-oriented commands to produce the connectivity which will support the desired broadband/multimedia call.

Claims

1. A method for effecting a broadband/multimedia call among a group of desired participants within an intelligent switched telecommunication network, comprising the steps of:

generating a high-level call control message in response to a call topology request;

executing one or more call configuration processes in response to said call topology request, thereby determining if said desired participants can accommodate the requested broadband/multimedia call;

generating a high-level connection control message, if as a result of the execution of said call configuration processes it is determined that said desired participants can accommodate the requested broadband/multimedia call; and

executing one or more connection configuration processes in response to said call topology request and said high-level call control message and high-level connection control message, thereby effecting interconnections within said intelligent switched telecommunication network which will support the requested broadband/multimedia call.

2. The method of claim 1 wherein each execution of a connection configuration process effects the transition from one state of network connectivity to another state of network connectivity.

3. The method of claim 1 wherein each of said connection configuration processes is one of a fixed collection of configuration processes achievable within said intelligent switched telecommunication network.

4. A method for effecting a broadband/multimedia call among a group of desired participants within an intelligent switched telecommunication network, comprising the steps of:

receiving a call topology request from one of said desired participants;

generating a high-level call control message in response to a said received call topology request;

executing one or more pre-programmed call configuration processes in response to said call topology request, thereby determining if said desired participants can accommodate the requested broadband/multimedia call;

generating a high-level connection control message, if as a result of the execution of said call configuration processes it is determined that said desired participants can accommodate the requested broadband/multimedia call; and

executing one or more pre-programmed connection configuration processes in response to said call topology request and said high-level control message and said high-level connection control message, thereby effecting interconnections within said intelligent switched telecommunication network which will support the requested broadband/multimedia call.

5. The method of claim 4 wherein each execution of a connection configuration process effects the transition from one state of network connectivity to another state of network connectivity.

6. The method of claim 4 wherein each of said connection configuration processes is one of a fixed collection of configuration processes achievable within said intelligent switched telecommunication network.

7. A method for effecting a broadband/multimedia call among a group of desired participants within an intelligent switched telecommunication network, comprising the steps of:

generating a high-level control message containing a call control message and a connection control message in response to a call topology request;

executing one or more call configuration processes in response to said call topology request, thereby determining if said desired participants can accommodate the requested broadband/multimedia call;

executing one or more connection configuration processes in response to said call topology request and said high-level control message if as a result of the execution of said call configuration processes it is determined that said desired participants can accommodate the requested broadband/multimedia call, thereby effecting interconnections within said intelligent switched telecommunication network which will support the requested broadband/multimedia call.

8. The method of claim 7 wherein each execution of a connection configuration process effects the transition from one state of network connectivity to another state of network connectivity.

9. The method of claim 7 wherein each of said connection configuration processes is one of a fixed collection of configuration processes achievable within said intelligent switched telecommunication network.

10. A method for effecting a broadband/multimedia call among a group of desired participants within an intelligent switched telecommunication network, comprising the steps of:

receiving a call topology request from one of said desired participants;

generating a high-level control message containing a call control message and a connection control message in response to said received call topology request;

executing one or more call configuration processes in response to said call topology request a said high-level control message, thereby determining if said desired participants can accommodate the requested broadband/multimedia call;

executing one or more connection configuration processes in response to said call topology request a said high-level control message if as a result of the execution of said call configuration processes it is determined that said desired participants can accommodate the requested broadband/multimedia call, thereby effecting interconnections within said intelligent switched telecommunication network which will support the requested broadband/multimedia call.

11. The method of claim 10 wherein each execution of a connection configuration process effects the transition from one state of network connectivity to another state of network connectivity.

12. The method of claim 10 wherein each of said connection configuration processes is one of a fixed collection of configuration processes achievable within said intelligent switched telecommunication network.
