Methods and systems for transmitting user part messages between signaling system seven (SS7) signaling points over an internet protocol (IP) network include receiving, at a signal transfer point, a first SS7 user part message. The first SS7 user part message can be received from a first SS7 signaling point, such as a service switching point (SSP). The first SS7 signaling point is encapsulated in a first IP packet. The first IP packet is transmitted to a second SS7 signaling point over an IP network.

Disclosed is a communications network element that is capable of routing signaling messages and also performing inter-network management functions in a converged telephony-data network environment. A signaling gateway routing node is adapted to facilitate signaling communication between nodes in a signaling system 7 network and nodes in an Internet protocol (IP) type network. In addition to basic message routing functionality, the signaling gateway routing node is adapted to notify nodes in the IP network when a node in the SS7 network becomes congested or unavailable. In certain cases, the signaling gateway selectively notifies only IP nodes that are concerned with the status of the troubled SS7 node, while in other cases, notification messages are broadcast to all relevant IP nodes. The signaling gateway also serves to filter redundant congestion status queries or polling type messages that are conveyed from IP nodes through to the distressed SS7 node.

Methods and systems for distributing operating status information within a converged network

A transport adapter layer interface (TALI) includes messages, processes, and packet structures for sending and receiving SS7 information over a stream-oriented connection, such as a TCP/IP connection. For example, the TALI interface includes test messages for testing the status of a connection and allow and prohibit messages for enabling and disabling service data communications without invoking a TCP handshaking procedure. The TALI interface also includes SYNC and LENGTH fields for facilitating extraction of individual message packets over a stream-oriented connection.

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.

Disclosed is a communications network element that is capable of routing signaling messages and includes a dynamic routing key registration feature which allows Internet protocol (IP) nodes to automatically register/de-register and subsequently direct traffic towards or away from themselves without the need for manual operator intervention. A signaling gateway routing node includes a self-registering data communication module (sDCM) that is adapted to receive and process dynamic routing key registration messages from associated IP nodes. Such dynamic routing key registration messages may include information that is used to register a new routing key association with a TCP/IP connection, de-register an existing routing key association with the TCP/IP connection, or modify routing key information associated with the TCP/IP connection.
