Methods and systems for communicating SS7 messages over packet-based network using transport adapter layer interface
First Claim
1. A method for monitoring the status of a stream-oriented connection used to communicate SS7 messages between SS7 and Internet protocol (IP) nodes, the method comprising:
- (a) establishing a first stream-oriented connection for communicating SS7 messages between a first signaling node and a second signaling node;
(b) transmitting a first message encapsulated in an IP packet over the first stream-oriented connection;
(c) listening for a reply to the first message over the first stream-oriented connection; and
(d) in response to failing to receive the reply within a predetermined time period, treating the first stream-oriented connection as being disabled.

Abstract
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.
