Abstract

A telecommunications management network (TMN) is directly connected for operation and maintenance data message exchange to a common channel signaling network. The direct connection to the telecommunications management network is made through a gateway one of a plurality of signal transfer points included within the telecommunications network. Addressing and format conversions are effectuated between the transmission control protocol/internet protocol (TCP/IP) used for the telecommunications management network operation and maintenance messages and the common channel signaling--signaling system no. 7 messages. The telecommunications management network and each of the network element nodes are accordingly assigned both an internet protocol address and a signaling system no. 7 (SS7) address. Static tables maintained in certain ones of the signal transfer points map internet protocol addresses and signaling system no. 7 (SS7) address against each other for message routing.

Claims

1. A telecommunications system, comprising:

a telecommunications network including;

a plurality of network element nodes interconnected by voice trunks wherein at least one of the network element nodes is a gateway node; and

a common channel signaling system connected to each of the network element nodes and configured to carry telecommunications application signals, the common channel signaling system supporting a transmission control protocol/internet protocol; and

a telecommunications management network connected to the at least one gateway node and to the plurality of network element nodes of the telecommunications network through the transmission control protocol/internet protocol of the common channel signaling system, with the transmission control protocol/internet protocol of the common channel signaling system carrying operation and maintenance data messages to and from the telecommunications management network through the gateway node, in addition to the telecommunications application signals carried on the common channel signaling system.

2. The system of claim 1 wherein the common channel signaling system comprises a signaling system no. 7 network.

3. The system of claim 2 wherein the transmission control protocol/internet protocol runs on top of the signaling system no. 7 network to carry the operation and maintenance data messages.

4. The system of claim 3 wherein the telecommunications management network as well as each of the network element nodes is assigned both an internet protocol address and a signaling system no. 7 address.

5. The system of claim 4 wherein the common channel signaling system maps internet protocol addresses to signaling system no. 7 addresses to route the operation and maintenance data messages.

6. The system of claim 5 wherein the common channel signaling system comprises a plurality of interconnected signal transfer points, and the at least one gateway node is a gateway signal transfer point through which a connection is made to the telecommunications management network.

7. The system of claim 6 wherein each of the signal transfer points functions as an internet protocol router for operation and maintenance data messages as well as a signaling system no. 7 router for telecommunications application signals.

8. The system of claim 1 wherein the network element nodes comprise telecommunications exchanges.

9. A telecommunications system, comprising:

a plurality of voice communications switching nodes interconnected by voice trunks;

a common channel signaling system comprising a plurality of signal transfer points interconnected by communications links, wherein certain ones of the signal transfer points are connected to certain ones of the plurality of voice communications switching nodes, and wherein one of the signal transfer points comprises a gateway signal transfer point, wherein the common channel signaling system carries telecommunications application signals, the common channel signaling system further supporting a transmission control protocol/internet protocol; and

a telecommunications management network connected to the gateway signal transfer point for the communication of operation and maintenance data messages with the plurality of voice communications switching nodes via the transmission control protocol/internet protocol supported by the common channel signaling system.

10. The system of claim 9 wherein the common channel signaling system comprises a signaling system no. 7 network.

11. The system of claim 10 wherein the common channel signaling system supports a transmission control protocol/internet protocol running on top of the signaling system no. 7 network.

12. The system of claim 11 wherein the telecommunications management network as well as each of the network element nodes is assigned both an internet protocol address and a signaling system no. 7 address.

13. The system of claim 12 wherein certain ones of signal transfer points include a static table mapping internet protocol addresses to signaling system no. 7 addresses.

14. The system of claim 13 wherein each of the signal transfer points functions as an internet protocol router for operation and maintenance data messages as well as a signaling system no. 7 router for telecommunications application signals.

15. A telecommunications system, comprising:

a common channel signaling telecommunications network including a plurality of switching nodes interconnected via a plurality of signal transfer points forming a signaling system no. 7 network, the signaling system no. 7 network supporting a transmission control protocol/internet protocol for carrying telecommunications management network operation and maintenance messages, the signal transfer points functioning as an internet protocol router for operation and maintenance data messages as well as a signaling system no. 7 router; and

a telecommunications management network connected to said common channel signaling telecommunications network via a gateway one of the plurality of signal transfer points.
