Abstract
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 Analysis
Total Claims: 12
Claim 1
Independent Claim
124 words
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, thereby effecting interconnections within said intelligent switched telecommunication network which will support the requested broadband/multimedia call.
Claim 2
Dependent Claim
28 words
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.
Claim 3
Dependent Claim
28 words
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.
Claim 4
Independent Claim
139 words
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, thereby effecting interconnections within said intelligent switched telecommunication network which will support the requested broadband/multimedia call.
Claim 5
Dependent Claim
28 words
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.
Claim 6
Dependent Claim
28 words
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.
Claim 7
Independent Claim
126 words
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, 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.
Claim 8
Dependent Claim
28 words
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.
Claim 9
Dependent Claim
28 words
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.
Claim 10
Independent Claim
138 words
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, 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, 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.
Claim 11
