Abstract
An apparatus and a method for performing handover between heterogeneous communication methods. A wireless power transmission apparatus and reception apparatus can indicate whether to support out-band communication thereof on the basis of an out-band flag. The wireless power transmission apparatus can request the wireless power reception apparatus to start a handover by using a bit pattern requesting the handover. The handover procedure to out-band may be performed in a negotiation phase or may be performed in a separate handover phase. Information for establishing an out-band communication connection can be transmitted from the wireless power reception apparatus to the wireless power transmission apparatus through in-band communication. Also, even after the handover to the out-band is completed, it is possible to periodically or intermittently perform the in-band communication in a power transmission phase to detect a swap of the wireless power reception apparatus.
