Abstract

A communication system utilizes an open system network protocol, such as the Transmission Control Protocol/Internet Protocol (TCP/IP), to transport Intelligent Network signaling messages from an SS7 network to a service provider which is not directly linked to the SS7 network. A gateway/bridge is provided between the SS7 network and a network which operates in accordance with an Internet protocol to transform Internet protocol messages, such as TCP/IP format messages, into SS7 format, and vice versa. In this way, an Internet protocol network may be used to transport Intelligent Network signaling messages between an SS7 network and a non-SS7 network service provider.

Claims

1. A method of providing signaling via a non-signaling protocol network, comprising:

receiving an encapsulated signaling request from a service provider via a communication network operating in accordance with an open system protocol, said service provider being an internet service provider or a special services provider that executes transactions via the internet;

replacing open system protocol layers of said encapsulated signaling request with signaling network protocol layers, thereby transforming said encapsulated signaling request into a signaling request of a signaling network protocol;

outputting said transformed signaling request to a signaling protocol network;

receiving a signaling response from a node of said signaling protocol network;

encapsulating said signaling response into an open system protocol message; and

sending said open system protocol message to said service provider via said communication network, said service provider performing an internet-related service based on said signaling response.

2. The method according to claim 1, wherein said node of said signaling protocol network is an Intelligent Network node.

3. The method according to claim 1, wherein said method provides an alternative path for transporting signaling messages.

4. The method according to claim 1, wherein said signaling network protocol is one of Signaling System Number 7 (SS7), a predecessor of SS7, and a variant of SS7.

5. The method according to claim 4, wherein said open system protocol is the Transmission Control Protocol/Internet Protocol (TCP/IP).

6. The method according to claim 1, wherein said special services provider sells merchandise over the internet using said signaling response.

7. The method according to claim 1, wherein

said replacing step transforms said encapsulated signaling request by,

stripping protocol stack layers below an application layer of said encapsulated signaling request, and

putting said stripped signaling request on top of protocol stack layers of said signaling network protocol; and wherein

said encapsulating step encapsulates said signaling response by,

stripping protocol stack layers below an application layer of said signaling response, and

putting said stripped signaling response on top of protocol stack layers corresponding to said open system protocol.

8. The method according to claim 7, wherein the application layer corresponds to a Transaction Capabilities Application Part (TCAP) format.

9. An apparatus for providing signaling via a non-signaling protocol network, comprising:

an input for receiving an encapsulated signaling request from a service provider via a communication network operating in accordance with an open system protocol, said service provider being an internet service provider or a special services provider that executes transactions via the internet;

an interface for replacing open system protocol layers of said encapsulated signaling request with signaling network protocol layers, thereby transforming said encapsulated signaling request into a signaling request of a signaling network protocol; and

an output for outputting said transformed signaling request to a signaling protocol network;

wherein said interface receives a signaling response from a node of said signaling protocol network, encapsulates said signaling response into an open system protocol message, and sends said open system protocol message to said service provider via said communication network, said service provider performing an internet-related service based on said signaling response.

10. The apparatus according to claim 9, wherein said node of said signaling protocol network is an Intelligent Network node.

11. The apparatus according to claim 9, wherein said apparatus provides an alternate path for transporting signaling messages.

12. The apparatus according to claim 9, wherein said signaling network protocol is one of Signaling System Number 7 (SS7), a predecessor of SS7, and a variant of SS7.

13. The apparatus according to claim 12, wherein said open system protocol is the Transmission Control Protocol/Internet Protocol (TCP/IP).

14. The apparatus according to claim 12, wherein said communication network is a packet-switched data network.

15. The apparatus according to claim 9, wherein said special services provider sells merchandise over the internet using said signaling response.

16. The apparatus according to claim 9, wherein

said interface transforms said encapsulated signaling request by,
