A link-up device disposed in a carrier network and communicatively coupled to a control device disposed outside the carrier network, the link-up device comprising:
- a processor;
- a memory that stores a program to be executed by the processor;
- and
- a subscriber database that stores information regarding a position of each of a plurality of interfering devices disposed in the carrier network,
- wherein the processor executes:
- processing of receiving a registration application including an ID of an interfering device of the plurality of interfering devices disposed in the carrier network from the interfering device;
- position information generation processing of setting position information that matches information stored in the subscriber database regarding the ID upon receiving the registration application;
- and
- processing of transmitting the position information to the control device that is disposed outside the carrier network for registration, the control device being responsible for (i) calculating an interference amount given by the plurality of interfering devices disposed in the carrier network to an interfered device disposed outside the carrier network and (ii) registering position information of each of the plurality of interfering devices.
