Latest Patents

One of Couillaud's latest patents is focused on media gateway connection information recovery. In a packet-based telephony network, a media gateway provides information on active media path connections to an active call server. This data may be provided to a backup call server to keep it in a warm standby mode. The backup call server polls the media gateway to retrieve a table of information on active media path connections, ensuring accurate billing information after a switchover or temporary failure at the active call server.

Another significant patent involves a transport mechanism for ISDN backhaul over IP. This method establishes and maintains a backhaul link over an Internet Protocol-based network for transporting Layer 3 ISDN messages. A signaling gateway establishes a TCP connection to a Media Gateway Controller through the IP-based network. The integrity of the TCP connection is monitored using a heartbeat mechanism based on UDP packets, allowing for the re-establishment of the backhaul link if necessary.
