Abstract

A telecommunications system comprises two groups of intelligent platforms in a common carrier'"'"'s network. Each intelligent platform includes an application or a service for processing a call related transaction. The intelligent platforms in each group are arranged in the Local Area Network configuration, such as a Fiber Distributed Data Interface, to transfer the call related transaction to each other for further processing. Each group of the intelligent platforms comprises a node on the Wide Area Network, such as an Asynchronous Transfer Mode (ATM), which provides the high speed support for transferring the call related transaction among the intelligent platforms of each group. The combination of these two transport mechanisms will provide a high speed interface and sufficient bandwidth for the projected increase in traffic volume.

Claims

1. A telecommunications system of a common carrier including a plurality of intelligent platforms for processing call related information, said system comprising:

a first local area network for connecting at least two intelligent platforms forming a first group in said plurality of intelligent platforms to transfer call related information therebetween;

a second local area network for connecting at least two other intelligent platforms forming a second group in said plurality of intelligent platforms to transfer call related information therebetween;

a switch for routing a telephone call from a calling station to a called station, said routing being selectively based on call related information held in said first group; and

a wide area network, responsive to said first local area network, to said second local area network, and to said switch, for providing a high speed interface to transfer call related information among said first group, said second group and said switch, wherein said first group of intelligent platforms includes call related information with a high transport priority if a data conflict occurs on said wide area network, and said second group of intelligent platforms includes call related information with a low transport priority if said data conflict occurs on said wide area network.

2. The system according to claim 1, wherein said first local area network comprises a fiber distributed data interface in said first group of intelligent platforms.

3. The system according to claim 1, wherein said second local area network comprises a fiber distributed data interface in said second group of intelligent platforms.

4. The system according to claim 1, wherein said high speed interface comprises an asynchronous transfer mode of communication between intelligent platforms of said first and second local area networks.

5. The system according to claim 1, wherein a throughput for non-billing transactions of call related information is at least 2,000 transactions per second.

6. The system according to claim 1, wherein each transaction of call related information comprises a 256 byte message, each byte comprising 8 bits.

7. A telecommunications system of a common carrier including a plurality of intelligent platforms for processing call related information, said system comprising:

a first local area network for connecting at least two intelligent platforms forming a first group in said plurality of intelligent platforms to transfer call related information therebetween, wherein one of said at least two intelligent platforms includes a switch for routing a telephone call from a calling station to a called station;

a second local area network for connecting at least two other intelligent platforms forming a second group in said plurality of intelligent platforms to transfer call related information therebetween; and

a wide area network, responsive to said first and second local area networks, for providing a high speed interface to transfer call related information between said first and second groups, wherein said first group includes call related information with a high transport priority such that if said switch requires additional information to provide a critical service, said additional information is obtained from an intelligent platform located on said first local network, and wherein said second group includes call related information with a low transport priority such that if said switch requires further information to provide a non-critical service, said further information is obtained, via said high speed interface, from an intelligent platform located on said second local network.

8. The system according to claim 7, wherein one of said at least two intelligent platforms on said first local area network includes a database.

9. The system according to claim 7, wherein said second group includes a database and a service resource platform.

10. The system according to claim 7, wherein said first local area network comprises a fiber distributed data interface in said first group of intelligent platforms.

11. The system according to claim 7, wherein said second local area network comprises a fiber distributed data interface in said second group of intelligent platforms.

12. The system according to claim 7, wherein said high speed interface comprises an asynchronous transfer mode of communication between intelligent platforms of said first and second local area networks.

13. The system according to claim 7, further comprising an additional intelligent platform connected to said first group and not connected to said first local area network, wherein said additional intelligent platform communicates with said second group of intelligent platforms via said first group and high speed interface.

14. A telecommunications system of a common carrier including a plurality of intelligent platforms for processing call related information, said system comprising:

a first local area network for connecting at least two intelligent platforms forming a first group in said plurality of intelligent platforms to transfer call related information therebetween, wherein one of said at least two intelligent platforms includes a switch for routing a telephone call from a calling station to a called station;

a second local area network for connecting at least two other intelligent platforms forming a second group in said plurality of intelligent platforms to transfer call related information therebetween; and

a wide area network, responsive to said first and second local area networks, for providing a high speed interface to transfer call related information between said first and second groups, wherein a new telecommunications service is initially developed and tested on an intelligent platform in said second group, and after development and testing said service is transferred, via said high speed interface, to another intelligent platform in said first group to be locally located with said switch, thereby quickly and efficiently achieving functional portability in said system.

15. The system according to claim 14, wherein said first local area network comprises a fiber distributed data interface in said first group of intelligent platforms.

16. The system according to claim 14, wherein said second local area network comprises a fiber distributed data interface in said second group of intelligent platforms.

17. The system according to claim 14, wherein said high speed interface comprises an asynchronous transfer mode of communication between intelligent platforms of said first and second local area networks.
