Abstract: Disclosed is a method for non-contact incoming call rejection and a communication system using the same. The method generally includes the steps of entering into a normal operation mode to check if a call rejection signal is received when a call message is received, checking, entering into a call rejection mode and turning off the prompt device if the call rejection signal is received, checking if the call rejection signal continues, turning off the call rejection mode and recovering the original settings of the prompt device if the call rejection signal does not continue, returning back to the normal operation mode, and repeating the subsequent steps. Therefore, the present invention automatically enters into the call rejection mode based on the call rejection message transmitted by the near field wireless communication device without performing any physical operation. Particularly, the present invention is suitable for the communication device for driving.
