Abstract

A telephone services functionality is disposed in a telecommunications network to ensure that a telephone call is processed in accordance with the telephone services respectively subscribed to by the calling and called parties. In addition, the functionality retains control over the call so that it may respond to service requests entered by either the calling or called party at any point following establishment of the call connection.

Claims

1. A method of processing a call between calling and called parties in a communications network formed from a plurality of network switches and providing a plurality of different communications services and associated features, said calling and called parties respectively subscribing to first and second ones of said communications services, said method comprising the steps of

at an originating one of said toll switches, receiving said call and associated calling information, and

identifying, as a function of said calling information, first and second network service processors operative for respectively implementing said first and second services in said network and passing said calling information to said first and second processors, such that said first and second processors cooperate with one another to respectively implement said first and second services and their associated features in said network on behalf of said calling and called parties, and

selecting as a function of said calling information one of said first and second processors to control the processing of said call.

2. The method of claim 1 wherein said step of receiving includes the step of

receiving routing information determined as a result of said first and second processors communicating with one another and forwarding said call to another one of said switches identified as a function of said routing information.

3. The method of claim 1 wherein said first and second services are different from one another.

4. The method set forth in claim 1 further comprising the steps of

assigning initial control of said call to said first processor, and

thereafter passing said control to said second processor.

5. The method set forth in claim 1 wherein said first service is a long distance service and said second service is a 900 service.

6. The method set forth in claim 4 further comprising the steps of responding to receipt of a respective telephone service request and passing said request to said controlling processor, and

responding to receipt of an instruction from said controlling processor by performing a telephone service functionality indicative of said request.

7. A method of processing a call in a telecommunications network comprising a plurality of interconnected toll switches, said network providing a plurality of different services, said call being originated by a calling party and being forwarded to a called party, said calling and called parties having independently selected respective first and second ones of said network services, said method comprising the steps of

at an originating one of said toll switches, responding to receipt of said call and associated calling information by identifying, as a function of said calling information, first and second network processors operative for respectively implementing said first and second services in said network, and

selecting, as a function of a number of parameters derived from said calling information, one of said first and second processors to control the processing of said call and supplying said calling information thereto, said first and second processors communicating with each other during the processing of said call so that said first and second services may be implemented in said network on behalf of said calling and called parties, respectively, and

responding to receipt of a routing indicator from one of said processors by forwarding said call to a second one of said switches identified as a function of said routing indicator.

8. The method set forth in claim 7 wherein said first service is a long distance service and said second service is a 900 service.

9. The method set forth in claim 7 further comprising the steps of responding at said first switch to receipt of a respective telephone service request and passing said request to said first or second processor based on said request being respectively entered by said calling or called party, and

responding to an instruction originating from said first or second processor by performing a telephone service functionality indicative of said request.
