Abstract
A method of maintaining communications between a mobile, wireless terminal and a base station of a wireless local area network is performed by determining at the base station, that communications between the base station and the terminal over a first channel on the wireless local area network has been impeded; and placing a telephone call to the terminal over a separate, distinct, second channel on a public switched telephone network. The caller ID of the incoming call is then used to verify the authenticity of the base station. Further communications continue over the second channel on the telephone network.
