Abstract:
1. A signaling control method for controlling a signaling process in a communication network system comprised of a management network, a control network, and a user data transmission network, the management network including a network management system, the control network including a plurality of control nodes connected to the management network for conducting signaling control, and the user data transmission network including a plurality of communication nodes consisting of first type communication nodes and second type communication nodes, the method comprising the steps of: setting one or more signaling-based communication apparatuses in the communications network system, each consisting of one of the control nodes and one of the first type communication nodes, said one of the first type communication nodes being connected to the associated control node and the management network; setting a non-signaling-based communication apparatus consisting of one of the second type communication nodes in the communications network system, the second type communication nodes being connected to the management network; causing the network management system to change a configuration of the second type communication node of the non-signaling-based communication apparatus when establishment of a path extending through the non-signaling-based communication apparatus is requested by one of the first type communication nodes located adjacent to one or a group of said second type communication nodes in the user data transmission network; and causing the control nodes of the signaling-based communication apparatuses to successively transmit a signaling message along the requested path in the control network to report the change of the configuration of the second type communication nodes, wherein the second type communication nodes constitutes a domain that includes only the non-signaling-based communication apparatuses, the method further comprising the step of: causing the network management system to change the configurations of the second type communication nodes of the non-signaling-based communication apparatuses located along the requested path in the domain when establishment of a path extending through the domain is requested.
