1. Apparatus, comprising:
- a first communications device to establish a first, wireless communication link with a remote unit, and a second communications device to establish a second communication link with the remote unit through the body of a person, anda controller to control operation, of the first and second communications devices;
wherein the controller, when in operation, instructs the second communication device to send a challenge through the second communication link to the remote unit, and based on a received response to the challenge over the second communication link that comprises an indication of whether the remote unit is in an operational state to communicate through the first, wireless communication link, the controller instructs the remote unit through the second communication link to switch between operational and non operational states regarding communication through the first wireless communication link.

Abstract
Wireless communication is provided between a mobile telephone handset and a headset worn by a person that uses the handset, through a first, wireless link such as Bluetooth. A second communication link is established by passing electrical currents between the handset and the headset through the body of the person. Communication through the second link is used to control operation of the first link.

24. A method comprising:
-
establishing, with a first communications device of a mobile communication apparatus, a first, wireless communication link between the mobile communication apparatus and a remote unit; establishing, with a second communications device of the mobile communication apparatus a second communication link between the mobile communication apparatus and the remote unit through the body of the person, and sending a challenge from the mobile communication apparatus through the second communication link to the remote unit; based on a response received with the second communications device over the second communication link to the challenge that comprises an indication of whether the remote unit is operable to communicate with the mobile communication apparatus through the first, wireless communication link, instructing the remote unit, with the second communications device through the second communication link, to switch between operational and non operational states regarding communication through the first, wireless communication link. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31)

32. A computer readable medium encoded with a computer program executable by at least one processor to perform operations comprising:
-
establishing, with a first communication device, a first wireless communication link with a remote unit; and establishing, with a second communication device, a second communication link with the remote unit through a body of a person, and controlling, with a controller, an operation of the first and second communications devices; wherein the controller, when in operation, instructs the second communication device to send a challenge through the second communication link to the remote unit, and based on a received response over the second communication link to the challenge that comprises an indication of whether the remote unit is in an operational state to communicate through the first wireless communication link, the controller instructs the remote unit through the second communication link to switch between operational and non operational states regarding communication through the first communication link.
