Claim 10:
11. A processing method implemented by a second wireless communication apparatus, the second wireless communication apparatus being one of a plurality of second wireless communication apparatuses included in a wireless communication system, the wireless communication system including a first wireless communication apparatus and the plurality of second communication apparatuses, the processing method comprising:
establishing a first communication channel that is a Device-to Device (D2D) communication channel directly with another one of the plurality of second wireless communication apparatuses, wherein the second wireless communication apparatus maintains an idle mode via a second communication channel when not in a connected mode via the second communication channel during a period of wireless communication via the first communication channel, the second communication channel being a cellular communication channel connected to a network of the wireless communication system via the first communication apparatus;
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 performs communication with the other one of the plurality of second wireless communication apparatuses via the first communication channel, the first processing including establishing the second communication channel with the first wireless communication apparatus.
