Secure connection for a public wireless communications device
A public telecommunications device ( 100, 201, 301, 401, 501, 901 ) configured to detect a channel connection-initiation signal ( 403, 503 ) from a wireless communications device ( 100, 202, 302, 402, 502, 902 ) which is paired with the public telecommunications device and render a prompt ( 408, 410 ) in response. The public telecommunications device will fully establish a wireless channel connection ( 306 ) with the wireless communications device only if the public telecommunications device detects a designated user input in response to the prompt ( 408, 410 ). If the public telecommunications device detects that a call ( 905 ) of the wireless communications device has ended, the wireless channel connection will be promptly terminated, unless a second designated user input is detected at the public telecommunications device. The risk of accidental or unintended connectivity to the public telecommunications device is thus minimized.
