  In step S1514, the communication terminal 400 determines whether or not communication start request information requesting to start wireless communication is received from the mobile terminal device 100. If the communication start request information is not received, the process returns to step S1514.

  In step S1516, when the communication terminal 400 receives communication start request information from the mobile terminal device 100, the communication terminal 400 starts wireless communication with the headset 200.

  According to the present embodiment, the mobile terminal device 100 connected to the headset 200 is connected to the communication terminal 400 that can communicate with the wireless LAN or the short-range wireless communication method via the wireless LAN, and the communication terminal 400 is searched for the periphery. And request communication with the headset 200. By doing so, it is not necessary to perform a peripheral search when switching the connection destination of the headset 200, so that the power consumption of the headset 200 can be reduced.
