  • Publication number: 20180192330
    Abstract: Provided are a communication control method, a communication control device, and a communication system that can appropriately change a device on a network that executes request processing from a terminal. In a node changing device 10, a sequence monitoring unit 12 detects handover of a UE 90. When the handover is detected, a placement calculation unit 14 acquires node information in the vicinity of a destination and activates nodes in the vicinity based on the node information. In this manner, upon detecting movement of a communication terminal, the node changing device 10 activates nodes in the vicinity of the destination of the communication terminal, and it is thereby possible to prevent an increase in communication delay even when the communication terminal is moved.
