To control a switch device using a mobile terminal, the owner of the mobile terminal stores caller identification data that includes call numbers associated with an authorized caller group, and switching control identification data associated with predetermined ring tone parameters. During activation of the mobile terminal, the mobile terminal establishes a communications link with a communications network. When caller data associated with an incoming call received by the mobile terminal matches the pre-stored caller identification data while, upon termination of the incoming call, the characteristics of ring tones generated by the incoming call match one of the predetermined ring tone parameters, the switch device is switched to a desired mode in response to a control signal outputted by the mobile terminal and associated with the switching control identification data that corresponds to the matching predetermined ring tone parameter.
