Abstract

Methods, systems, and computer program products for managing and selectively distributing routing information in a routing node are disclosed. In one implementation, a method for selectively distributing routing information in a routing node includes organizing internal signaling resources are organized so as to facilitate the efficient mapping of signaling system 7 (SS7) message transfer part (MTP) signaling protocol attributes to Internet protocol (IP)-based signaling resources. A routing status information sharing hierarchy is defined, which enables routing status information to be efficiently shared among members of a signaling mateset group. Members of a signaling mateset replicate and distribute SS7 MTP network management information across non-MTP signaling connections, such as IP connections.

Claims

1. A method for managing and selectively distributing routing status information in a message routing system which includes at least one communication interface for communicating signaling system 7 (SS7) information over a non-message-transfer-part (MTP) transport protocol, the method comprising:

(a) assigning a plurality of non-MTP-transport communication modules within a signaling message routing node to a first signaling mateset (SM) group for distribution of non-MTP routing status information;

(b) communicating non-MTP routing status information associated with the first SM group among the communication modules in the first SM group, wherein communicating the non-MTP routing status information among the communication modules in the first SM group includes limiting the communication of the non-MTP routing status information from the communication modules in the first SM group to the communication modules in the first SM group; and

(c) communicating MTP routing status information associated with the first SM group to at least one communication module within the signaling message routing node that is not in the first SM group.

2. The method of claim 1 wherein assigning a plurality of non-MTP transport communication modules in the system to a first SM group includes assigning a plurality of Internet protocol (IP) transport communication modules to the first SM group.

3. The method of claim 2 wherein assigning a plurality of IP transport communication modules to a first SM group includes assigning a plurality of data communication modules (DCMs) to the first SM group.

4. The method of claim 1 wherein assigning a plurality of non-MTP transport communication modules to a first SM group includes assigning a plurality of asynchronous transfer mode (ATM) transport communication modules to the first SM group.

5. The method of claim 1 comprising associating a virtual SS7 signaling link entity with each communication module in the first SM group.

6. The method of claim 1 wherein communicating non-MTP routing status information includes communicating IP destination status information.

7. The method of claim 1 wherein communicating non-MTP routing status information includes communicating IP connection status information.

8. The method of claim 1 wherein communicating MTP routing status information includes communicating SS7 MTP level 3 route status information.

9. The method of claim 1 wherein communicating MTP routing status information includes communicating virtual SS7 signaling link entity status information.

10. A method for managing and distributing signaling system 7 (SS7) network management (NM) information in a message routing system including at least one communication interface adapted to communicate signaling system 7 (SS7) information over at least one non-message-transfer-part (MTP) transport protocol signaling connection, the method comprising:

at a first communication module that includes at least one non-MTP transport protocol based signaling connection, wherein the first communication module is within a signaling message routing node;

(a) receiving a message that includes SS7 network management information;

(b) determining a network type associated with the received SS7 network management information; and

(c) communicating the SS7 network management information over non-MTP transport protocol signaling connections of the signaling message routing node associated with the determined network type, wherein communicating the SS7 network management information among the over the non-MTP transport protocol signaling connections of the signaling message routing node associated network type includes limiting the communication of the SS7 network management information to the non-MTP transport protocol connections of the signaling message routing node associated with the determined network type.

11. The method of claim 10 wherein receiving a message that includes SS7 network management information at a first communication module includes receiving SS7 network management information at a communication module that includes an Internet protocol (IP) signaling connection.

12. The method of claim 10 wherein receiving a message that includes SS7 network management information at a first communication module includes receiving SS7 network management information from a second communication module in the routing system.

13. The method of claim 10 wherein determining a network type associated with the received SS7 network management information includes examining a national network indicator parameter associated with the network management information.

14. The method of claim 10 wherein determining a network type associated with the received SS7 network management information includes examining message origination information associated with the network management information.

15. The method of claim 10 wherein determining a network type associated with the received SS7 network management information includes examining concerned point code information associated with the network management information.

16. The method of claim 10 wherein determining a network type includes determining whether network management information is associated with an American National Standards Institute (ANSI) signaling network.

17. The method of claim 10 wherein determining a network type includes determining whether network management information is associated with an International Telecommunications Union (ITU) signaling network.

18. The method of claim 10 wherein communicating the SS7 network management information over non-MTP transport protocol signaling connections includes communicating the SS7 network management information over an IP connection.

19. The method of claim 10 wherein communicating the SS7 network management information includes replicating the SS7 network management information and communicating the replicated SS7 network management information over multiple IP connections.

20. A method for distributing SS7 network management information collected by a plurality of non-MTP communication modules in a signaling message routing node, the method comprising:

(a) organizing a plurality of non-MTP communication modules within a signaling message routing node into a group for distribution of non-MTP signaling connection status information, wherein the distribution of the non-MTP signaling connection status information includes limiting the communication of the non-MTP signaling connection status information from the communication modules in the group to the communication modules in the group;

(b) designating one of the non-MTP communication modules in the group as a proxy for distributing MTP network management information to communication modules within the signaling message routing node that are not members of the group; and

(c) using the proxy to distribute MTP network management information to communication modules within the signaling message routing node that are not members of the group.

21. A computer program product comprising computer executable instructions embodied in a computer readable medium for performing steps comprising:
