Abstract: A communication apparatus receives a use request to use a function of the communication apparatus from an external device via a communication unit. When the use request is received, the communication apparatus acquires a first identifier for identifying the external device as a request source which requests the use of the function. Based on the acquired first identifier and a second identifier for identifying an external device which requests power supply by a power transmission unit, the communication apparatus determines whether to cause the power transmission unit to transmit power to the external device. If it is determined to transmit power, the communication apparatus transmits, via the power transmission unit, power to the external device which requests power supply.

In accordance with another embodiment, a first terminal may switch its proximity service communication technology for better QoS without network assistance. The first terminal monitors link status. If the link status is deteriorated, the first terminal requests a second terminal to change proximity service communication technology.
