Method and System for Implementing Redundancy at Signaling Gateway Using Dynamic SIGTRAN Architecture
First Claim
1. A computer-implemented method for implementing signaling gateway redundancy, the computer-implemented method comprising:
- receiving, at a first signaling gateway host, a first Signaling Transport (SIGTRAN) protocol application server process maintenance message from a first application server process;
updating connection control information associated with one or more connections to the first signaling gateway host based on the first SIGTRAN protocol application server process maintenance message; and
transmitting, from the first signaling gateway host, a second SIGTRAN protocol application server process maintenance message to a second signaling gateway host, the second SIGTRAN protocol application server process maintenance message based on the first SIGTRAN protocol application server process maintenance message, the second signaling gateway host being mated with the first signaling gateway host.

Abstract
Described are a method, a computer program product and apparatus for implementing signaling gateway redundancy. A first SIGTRAN protocol application server process maintenance message is received, at a first signaling gateway, from a first application server process. Connection control information associated with one or more connections to the first signaling gateway is updated based on the first SIGTRAN protocol application server process maintenance message. A second SIGTRAN protocol application server process maintenance message is transmitted, from the first signaling gateway, to a second signaling gateway. The second SIGTRAN protocol application server process maintenance message is based on the first SIGTRAN protocol application server process maintenance message. The second signaling gateway is mated with the first signaling gateway.
