Claim 0:
1. An IP network common-channel link setting device 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 device comprising:
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;
a link management device that manages logical links for a common channel on the IP network;
a processor; and
a memory device storing instructions that, when executed by the processor, cause the processor to perform operations comprising:
defining a correspondence between a point code representing the signal transfer point as a connection destination and an IP address of the corresponding signal transfer point,
determining at least an IP address of the signal transfer point as the connection destination based on the point code included in a request from the IP converter device and notifying the IP converter device as a request source of the determined IP address of the signal transfer point, and notifying the determined signal transfer point of information on the IP converter device as the request source,
allowing connection from the IP converter device based on the information notified by the link management device, and
establishing a link with the signal transfer point determined as the connection destination by the link management device based on the information notified by the link management device.
