To provide a radio communication method and radio communication device, capable of making a user such as an occupant recognize a possible cause of blocking when radio communication is blocked.SOLUTION: When a portable device 3 is brought into a predetermined range from a radio communication device in a cabin or the like, bluetooth communication is executed between an on-vehicle device 100 and the portable device 3. When bluetooth communication is monitored and blocking is detected in the bluetooth communication, BTLE communication with lower power consumption than bluetooth communication is executed relative to the portable device 3. The BTLE communication estimates a possible cause of the blocking. Thus, an occupant can be completely notified of the possible cause of the blocking.SELECTED DRAWING: Figure 1
【課題】無線通信が遮断した際に、遮断の原因を乗員等のユーザに認識させることが可能な無線通信方法及び無線通信装置を提供する。【解決手段】車室内等の無線通信装置から所定の範囲内に携帯機3が持ち込まれた際に、車載機100と携帯機3との間でブルートゥース通信を行う。ブルートゥース通信を監視し、該ブルートゥース通信に遮断を検出した場合には、携帯機3との間で、ブルートゥース通信よりも消費電力が低いBTLE通信を行う。BTLE通信により、遮断が発生した原因を推定する。遮断の原因を確実に乗員に知らせることが可能となる。【選択図】 図1
