PURPOSE: A link control method is provided to prevent issues occurred when a service to a wrong connected link is performed. CONSTITUTION: In a link control method, a link discrimination is requested to a link exchange(300), and a link discrimination confirming message is received from the link exchange(302). Whether an ID requesting a link discrimination is identical to a received ID is judged(304). If not, the link discrimination is treated as an abnormality(310), and a link discrimination release request is sent to the link exchange(312). A corresponding link is blocked so that a service into the corresponding link is impossible(314). The link discrimination request number and a link number of receiving a response are stored in a database of a system(316), and then is displayed through a monitor(318).
