Claim 5:
6. 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.
