Abstract: The present invention provides a method for providing a service to a device having an interest in a specific service in a device-to-device (D2D) condition. The method includes: searching for a device which enters into an area managed by a device which provides the specific service; and identifying an interest of the searched device in the specific service and inviting the searched device to participate in the specific service. In the method, by selectively connecting a session based on a service interest, an efficient management in view of an entire network capacity is possible and an advantage of reducing a time for session connection is achieved.

Abstract: Disclosed is a method for controlling a wireless power transmitter for transmitting charging power to a wireless power receiver. The control method of the present invention comprises the steps of: adjusting the internal impedance of the wireless power transmitter such that the impedance variation occurring when the wireless power receiver is positioned is set to a second impedance variation different from the first impedance variation; applying detection power for detecting the wireless power receiver; detecting the second impedance variation during the application of the detection power so as to detect the wireless power receiver; and changing the impedance variation occurring when the wireless power receiver is positioned from the second impedance variation to the first impedance variation.
