To provide a communication device, a communication system, and a communication control method that enable smooth communicating with a server.SOLUTION: A master device 30 comprises a wide area radio communication unit 35 and a control unit 32. The wide area radio communication unit 35 communicates with a center side network controller 20. When it is determined that the wide area radio communication unit 35 in a connection state with the center side network controller 20 has become into a response waiting state within a third predetermined period T3, the control unit 32 controls the wide area radio communication unit 35 so that the wide area radio communication unit 35 transmits a dummy signal for elongating a period of the connection state before the period of the connection state ends.SELECTED DRAWING: Figure 9 【課題】サーバと円滑に通信することができる通信装置、通信システム、及び通信制御方法を提供する。【解決手段】親機３０は、広域無線通信部３５と、制御部３２とを備える。広域無線通信部３５は、センタ側網制御装置２０と通信する。制御部３２は、センタ側網制御装置２０と接続状態の広域無線通信部３５が第３所定期間Ｔ３内に応答待ちの状態になったと判断すると、接続状態の期間が終了するよりも前に、広域無線通信部３５が接続状態の期間を延長するためのダミー信号を送信するように広域無線通信部３５を制御する。【選択図】図９
