COMMUNICATION DEVICE, SYSTEM, AND CONTROL PROGRAM

To prevent pairing unintended by users in wireless communication.SOLUTION: A main body device (10) includes: a first receiving unit (11) that receives a first signal on an omnidirectional transmission path; a second receiving unit (12) that receives a second signal on a directional transmission path; and a determination unit (13) that refers to identification information contained in the first signal and identification information indicated by the second signal and determines whether to perform pairing of omnidirectional transmission with a device corresponding to the identification information.SELECTED DRAWING: Figure 1 【課題】無線通信においてユーザの意図しないペアリングを防止する。【解決手段】本体装置（１０）は、無指向性伝送経路にて第１信号を受信する第１受信部（１１）と、指向性伝送経路にて第２信号を受信する第２受信部（１２）と、第１信号に含まれる識別情報と第２信号が示す識別情報とを参照して、当該識別情報に対応する装置との無指向性伝送のペアリングを行うか否かを決定する決定部（１３）と、を備えている。【選択図】図１
