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.
