COMMUNICATION CONTROL METHOD, COMMUNICATION CONTROL PROGRAM, AND COMMUNICATION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To improve efficiency of two-way communication with a client device.SOLUTION: A communication control device 101 connects with a client device 102 if it has accepted a connection request R1 from the client device 102. The communication control device 101 refers to a storage unit 110 and determines whether an update frequency F of data D requested by the client device 102 during connection is less than a threshold value For not. The communication control device 101 transmits a reconnection instruction to the client device 102 if the update frequency F of the data D is less than the threshold value F. The communication control device 101 disconnects connection with the client device 102 as a result of transmitting the reconnection instruction. The client device 102 changes a communication mode with the communication control device 101 from stateful communication to stateless communication if it has accepted the reconnection instruction from the communication control device 101.
