  • Publication number: 20110078274
    Abstract: Described are a method, a computer program product and apparatus for implementing signaling gateway redundancy. A signaling network management message is received, at a first signaling gateway, from a first signaling network. Routing control information associated with the first signaling gateway is updated based on the signaling network management message. A first SIGTRAN protocol signaling network management message is transmitted, from the first signaling gateway, to a first application server on a first IP network. The first SIGTRAN protocol signaling network management message is based on the signaling network management message. A second SIGTRAN protocol signaling network management message is transmitted, from the first signaling gateway, to a second signaling gateway on a second IP network. The second SIGTRAN protocol signaling network management message is based on the signaling network management message. The second signaling gateway is mated with the first signaling gateway.

  • Publication number: 20110075654
    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.

  • Patent number: 5990933
    Abstract: In a multipoint control unit for conferencing audiovisual terminals, conference participants are greeted with audio and video welcome messages and then placed in an automated queue. The automated queue is a holding queue from which a conference operator can select the next available conference participant in the queue and conduct a subconference. Apparatus in the multipoint control unit includes a memory for storing video data and a processor coupled to the memory for controlling playback of the video data to a connected terminal during conference setup.
