ABSTRACT:
TECHNICAL FIELD
This invention relates generally to wireless switching systems and, in particular, to control of a wireless telephone.
BACKGROUND OF THE INVENTION
Studies have indicated that talking on a wireless telephone while driving increases the risk of an accident. Part of the increased risk is attributed to drivers being distracted by a wireless telephone ringing. This risk can be abated by the users turning their wireless telephones off when they enter a vehicle and turning it on when they exit or come to a complete stop. However, few users perform these actions every time they enter or exit a vehicle. Certain foreign countries make it illegal to utilize a wireless telephone at anytime while driving an automobile. However, a user could easily forget about this prohibition and originate or receive a call while driving an automobile.
SUMMARY OF THE INVENTION
The foregoing problems are solved, and a technical advance is achieved by an apparatus and method in which a wireless telephone does not generate an alerting signal for an incoming call if the speed at which the wireless telephone is moving exceeds a predefined speed. Advantageously, if an alerting signal is not generated for an incoming call, the wireless telephone transmits an audio message back to the calling party informing them that they have contacted the wireless telephone and may leave either a voice or data message. Further, the wireless telephone must have been below the predefined speed for a predefined amount of time before the alerting signal will be generated. 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 are blocked.
