Abstract
A wireless telephone does not generate an alerting signal if the speed at which the wireless telephone is moving exceeds a predefined speed when an incoming call is received. If an alerting signal is not generated for an incoming call, the wireless telephone transmits a message back to the calling party informing them that they have contacted the wireless telephone and may leave either a voice or data message. The caller can then either leave a voice message or touch tone in the caller's telephone number. Further, the wireless telephone can inhibit the origination of calls from the wireless telephone if the speed of the wireless telephone exceeds the predefined speed. In addition, if the speed has not been equal or less than the predefined speed for a predefined amount of time, call originations and alerting signals are blocked.
