SOLUTION: The method of refusing a connection change request has: a step of establishing first connection to a first node; a step of passing through a second node and the first one and establishing second connection having a first related end-to-end state; a step of relaying a first request for changing the second connection to the second node by the first node for transmitting to the second node to achieve a second end-to-end state to which the second connection is related; a step of receiving a refusal message indicating that the first change request of the second connection has failed from the first node; and a step of transmitting a second request for changing the second connection to the second node to set the second connection to be the first related end-to-end state again.
