IP network common line link setting device, IP network common line link setting method, IP network common line link setting program,and IP network common line link setting system

An IP network common-channel link setting method for allocating a plurality of logical links with different paths on a communication system that transfers a common-channel signal for controlling connection between a plurality of exchanges via an IP network, the method comprising:

• in an environment in which the communication system includes a plurality of independent IP converter devices for connecting each exchange to the IP network, a plurality of signal transfer points connected to the IP network, and a link management device that manages logical links for a common channel on the IP network,
• transmitting, from the IP converter device to the link management device, at least information on a point code representing the signal transfer point as a connection destination;
• determining, with the link management device, an IP address of the signal transfer point as the connection destination based on the point code;
• transmitting information on the IP converter device from the link management device to the signal transfer point identified by the determined IP address;
• transmitting information on the signal transfer point identified by the determined IP address from the link management device to the IP converter device;
• and
• performing communication for establishing a link between the IP converter device and the signal transfer point based on the information received from the link management device.

An IP network common-channel link setting program used for allocating a plurality of logical links with different paths on a communication system that transfers a common-channel signal for controlling connection between a plurality of exchanges via an IP network, the program being executable in an environment in which the communication system includes a plurality of independent IP converter devices for connecting each exchange to the IP network, a plurality of signal transfer points connected to the IP network, and a link management device that manages logical links for a common channel on the IP network, by a predetermined computer that controls the IP converter device, the signal transfer point, and the link management device, the program comprising:

• transmitting, from the IP converter device to the link management device, at least information on a point code representing the signal transfer point as a connection destination;
• determining, with the link management device, an IP address of the signal transfer point as the connection destination based on the point code;
• transmitting information on the IP converter device from the link management device to the signal transfer point identified by the determined IP address;
• transmitting information on the signal transfer point identified by the determined IP address from the link management device to the IP converter device;
• and
• performing communication for establishing a link between the IP converter device and the signal transfer point based on the information received from the link management device.
