SOLUTION: When a portable terminal 1 and an accessory 2 are started, the accessory 2 discriminates the presence of a request of ID code registration and sends an ID transmission request to the portable terminal 1 when the request exists. The portable terminal 1 generates an ID code on the basis of a telephone number and transmits the ID code in response to the ID transmission request. The accessory 2 receives it and stores it. When the portable terminal 1 receives an incoming call, the portable terminal 1 adds its own ID code to the incoming information and transmits the resulting information to the accessory 2. The accessory 2 discriminates whether or not the ID code sent by the portable terminal 1 is registered in response to the incoming call and reports the arrival of the incoming call in sound or light when registered.
