Claim 12:
13. A processing method implemented by a first wireless communication apparatus included in a wireless communication system, the wireless communication system including the first wireless communication apparatus a second wireless communication apparatus, and a third wireless communication apparatus, the processing method comprising:
establishing a second communication channel with the third wireless communication apparatus, the third wireless communication apparatus being configured to communicate with the second wireless communication apparatus via a first communication channel that is a Device-to Device (D2D) communication channel established directly between the third wireless communication apparatus and the second wireless communication apparatus, the second communication channel being a cellular communication channel connected to a network of the wireless communication system via the first communication apparatus, wherein the second wireless communication apparatus maintains an idle mode via the second communication channel when not in a connected mode via the second communication channel during a period of wireless communication with the third wireless communication apparatus via the first communication channel; and
receiving, from the third wireless communication apparatus, data destined for the second wireless communication apparatus via the second communication channel,
performing first processing when a line disconnection is detected after a first state continues for a predetermined time, the first state being a state where a quality of the first communication channel is poorer than a predetermined quality in a case where the second wireless communication apparatus operates in the idle mode via the second communication channel during the period the second wireless communication apparatus communicates with the third wireless communication apparatus via the first communication channel, the first processing including establishing the second communication channel with the second wireless communication apparatus.
