Jun 5, 2002

Appl. No.:

10/164226

Inventors:

David Michael Sprague - Raleigh NC, US
Mark Edward Kanode - Apex NC, US
Dan Alan Brendes - Raleigh NC, US
Mark Ernest Davidson - Chapel Hill NC, US

Assignee:

Tekelec - Morrisville NC

International Classification:

H04J 3/12

US Classification:

370524, 370467

Abstract:

A normalizing signaling gateway (NSG) routing node receives a first signaling message formatted according to a first variant of a common or standard signaling protocol, such as ISUP, and creates a second signaling message based on the first message. The second signaling message includes a normalized component and a variant component. The second signaling message may then be routed to a second NSG routing node or to a media gateway controller. Because the NSG routing node converts messages to and from variants of a standard signaling protocol, the media gateway controller is not required to support all of the variants of the standard signaling protocol, and its complexity is reduced.

International Classification:

H04M 7/00

US Classification:

379229, 37922101, 379219

Abstract:

A duplicate point code routing node is capable of routing messages to nodes having the same point code but being located in different national networks. The duplicate point code routing node associates a group code with received messages and uses the group code to route the messages to the appropriate national network. The group code may be determined based on the link or linkset from which a message is received or from the message itself.

US Classification:

370236, 370469

Abstract:

The subject matter described herein includes methods, systems, and computer program products for managing congestion in a multi-layer telecommunications signaling network protocol stack. According to one method, a congestion parameter is set for a first layer in a telecommunications signaling network protocol stack. The congestion parameter is automatically propagated for at least one second layer in the telecommunications signaling protocol stack. The first layer and the at least one second layer are monitored and layer-specific congestion management procedures are triggered using the parameters.

Abstract:

According to one aspect, the subject matter described herein comprises methods, systems, and computer program products for performing IP link proving using heartbeat messages. The method includes transmitting a plurality of heartbeat messages over an IP communications link. A transmission parameter of the plurality of heartbeat messages is varied and a plurality of heartbeat acknowledgement messages corresponding to at least a subset of the plurality of heartbeat messages is received. A measure of processing capabilities of the IP communications link is determined based on the transmission parameters and the heartbeat acknowledgement messages.

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.

Abstract:

According to one aspect, the subject matter described herein includes a method for routing Diameter messages. The method includes steps occurring at a Diameter signaling router (DSR) comprising a plurality of Diameter message processors. The method also includes receiving, by a first of the plurality of Diameter message processors and from a first Diameter node, a Diameter message, wherein the Diameter message is received via a first Diameter connection. The method further includes determining, by the first Diameter message processor, a next-hop Diameter node for the Diameter message. The method further includes communicating, by the first of the plurality of Diameter message processors and to a second of the plurality of Diameter message processors, the Diameter message. The method further includes communicating, by the second Diameter message processor and to the next-hop Diameter node, the Diameter message, wherein the Diameter message is communicated via a second Diameter connection.

Abstract:

Methods, systems, and computer readable media for providing local application routing at a Diameter node are disclosed. One method includes receiving, at an ingress Diameter message processor associated with a Diameter signaling router (DSR), a Diameter message from a peer Diameter element. At the ingress Diameter message processor, application routing data is accessed to determine whether processing of the Diameter message by a Diameter application is required. In response to determining that Diameter application processing is required, the Diameter message is forwarded to a Diameter message processor hosting a Diameter application identified by the application routing data for processing. In response to determining that Diameter application processing is not required, the Diameter message is forwarded to an egress Diameter message processor associated with the DSR.
