  • Signaling protocol supporting multimedia services employing an automation with multiple states and a state matrix indicating the states of multiple entities
    Patent number: 5678008
    Abstract: This protocol consists in, among other things, updating in all the terminals and in all the nodes of the telecommunication network which a given call concerns a matrix representing the status of each terminal (TA, TB, TC) which is a party to the call in question vis-a-vis each connection (C1, C2, C3) set up for the call in question. This matrix distinguishes a plurality of fine states within the active state of each of the terminals and the nodes that this call concerns. This matrix is generally updated by means of a message which is broadcast throughout the network when an operation is executed in one of the terminals and modifies: the state of this call, or of a connection set up for this call, or of a terminal participating in this call.
