Abstract

A protocol interface gateway connects a telecommunication system emulator to a communications network. The gateway receives signals from the network and sends signals to the network that are formatted in a network protocol. The gateway converts signals received from the network into instructions in emulator code, and sends the instructions in emulator code to the emulator for processing. The emulator executes code in blocks of application software utilized in a target telecommunications node. The gateway then receives the processed instructions in emulator code from the emulator, converts the processed instructions into signals formatted in the network protocol, and sends the signals to the communications network. The protocol interface gateway utilizes a UNIX socket that replaces Open Systems Interconnection (OSI) layers 1 and 2 of the network protocol to send and receive the signals from the network.

Claims

1. A protocol interface gateway for connecting a telecommunication system emulator to a data network, said gateway comprising:

means for receiving data signals from said data network and sending data signals to said data network, said data signals formatted in a data network protocol;

means for converting said data signals into telecommunication signals formatted in a telecommunication network protocol, and for converting said telecommunication signals into said data signals;

means for converting said telecommunication signals into instructions in emulator code, and converting processed instructions in emulator code into telecommunication signals in said telecommunication network protocol; and

means for sending said instructions in emulator code to said emulator and receiving said processed instructions in emulator code from said emulator.

2. The protocol interface gateway of claim 1 wherein said means for receiving data signals from said data network formatted in a data network protocol includes a UNIX socket that replaces Open Systems Interconnection (OSI) layers 1 and 2 of said data network protocol.

3. The protocol interface gateway of claim 2 wherein said means for receiving data signals from said data network formatted in a data network protocol includes means for receiving data signals formatted in any Signaling System 7 (SS7) compatible protocol.

4. The protocol interface gateway of claim 3 wherein said emulator includes means for emulating a target telecommunication node by processing said instructions in emulator code and, in turn, executing code in blocks of application software utilized in said target telecommunication node.

5. The protocol interface gateway of claim 4 wherein said data network is a local area network (LAN).

6. The protocol interface gateway of claim 5 wherein said local area network is an Ethernet LAN.

7. A method of connecting a telecommunication system emulator to a data network, said emulator emulating a target telecommunications node, said method comprising the steps of:

receiving data signals from said data network with a protocol interface gateway, said data signals formatted in a data network protocol;

converting, in said protocol interface gateway, said received data signals into telecommunication signals formatted in a telecommunication network protocol;

converting, in said protocol interface gateway, said telecommunication signals into instructions in emulator code;

sending said instructions in emulator code from said protocol interface gateway to said emulator for processing;

executing in said emulator, code in blocks of application software utilized in said target telecommunications node;

receiving said processed instructions in emulator code from said emulator with said protocol interface gateway;

converting, in said protocol interface gateway, processed instructions in emulator code into telecommunication signals in said telecommunication network protocol;

converting, in said protocol interface gateway, said telecommunication signals into data signals formatted in said data network protocol; and

sending said data signals in said data network protocol from said protocol interface gateway to said data network.

8. The method claim 7 wherein said step of receiving data signals from said data network formatted in a data network protocol includes replacing Open Systems Interconnection (OSI) layers 1 and 2 of said data network protocol with a UNIX socket.

9. The method claim 8 wherein said step of receiving data signals from said data network formatted in a data network protocol includes receiving signals formatted in any Signaling System 7 (SS7) compatible protocol.

10. The method of claim 9 wherein said step of receiving data signals from said data network with said protocol interface gateway includes receiving said data signals from a local area network (LAN).

11. The method of claim 10 wherein said step of receiving said data signals from a local area network includes receiving said data signals from an Ethernet LAN.

12. A method of communicating between a first telecommunications node and a second telecommunications node over a data network, said method comprising the steps of:

encapsulating messages in a telecommunications protocol in the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol;

connecting the first telecommunications node to a data network utilizing a first Internet socket connection;

connecting the second telecommunications node to the data network utilizing a second Internet socket connection; and

transmitting encapsulated telecommunications protocol messages via said data network from said first telecommunications node to said second telecommunications node.

13. The method of communicating between a first telecommunications node and a second telecommunications node of claim 12 wherein said step of encapsulating messages in a telecommunications protocol in the TCP/IP protocol includes encapsulating Signaling System 7 (SS7) messages in the TCP/IP protocol.

14. The method of communicating between a first telecommunications node and a second telecommunications node of claim 13 wherein said step of transmitting encapsulated telecommunications protocol messages via said data network from said first telecommunications node to said second telecommunications node includes transmitting encapsulated SS7 messages via said data network from said first telecommunications node to said second telecommunications node in the TCP/IP protocol.

15. The method of 1 between a first 1 node and a second telecommunications node of claim 14 wherein said steps of connecting the first telecommunications node to a data network and connecting the second telecommunications node to a data network include connecting the first and second telecommunications nodes to the Internet utilizing said first and second Internet socket connections.

16. The method of communicating between a first telecommunications node and a second telecommunications node of claim 14 wherein said step of connecting the first telecommunications node to a data network utilizing a first Internet connection includes the steps of:

connecting the first telecommunications node to a first local area network (LAN); and

connecting the first LAN to the Internet.

17. The method of communicating between a first telecommunications node and a second telecommunications node of claim 16 wherein said step of connecting the second telecommunications node to a data network utilizing a second Internet socket connection includes the steps of:

connecting the second telecommunications node to a second LAN; and

connecting the second LAN to the Internet.
