A method of identifying a second caller when a handheld device is busy with a first caller, comprising the steps of: (a) receiving an ID from the second caller; (b) comparing the ID of the second caller with an ID database of the handheld device for finding out corresponding call waiting data; and (c) outputting a call-waiting signal corresponding to the call waiting data. Hence the method can alert a mobile phone user via a sound signal, a light signal, a vibration signal or a combination thereof to know that who is a second caller without looking a caller display. Thereby the user can determine to receive the calling or not from the second caller without looking the caller display.
