Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for receiving a melody tone in a call waiting state in which when a new subscriber receives a new incoming call, the subscriber can suspend the communication state and respond to the incoming call. The present invention relates to a call waiting method with a melody notification function for notifying a call waiting by using the function.

[0002]

2. Description of the Related Art With the development of mobile communication, there is a social demand for various functions for incoming and outgoing calls. Also,
With a reduction in mobile phone charges, one communication hold time becomes longer, and incoming calls to subscribers in communication, for example, incoming calls such as call waiting incoming calls, are also increasing. Furthermore, the identification of the identity of a person who can identify who received a call has also become widespread due to the social penetration of the calling number notification function.

[0003] In addition, the performance of portable terminals has been improved, and the ringing melody has been diversified. For example, a plurality of ringing melodies are possible, and further, chords of the ringing melodies are performed.

[0004] In the above-described situation, call waiting enables a new incoming call to a communicating subscriber, but is transmitted to a communicating subscriber in conventional call waiting. The call-waiting ringtone is not the melody tones diversified as described above, e.g., diversified differently for each call-waiting caller, but is the same for all subscribers, so that the communicating subscribers The call waiting incoming call cannot be identified from whom.

Referring to FIG. 7, a conventional call waiting will be described. As shown in FIG. 7, when the subscriber A and the subscriber B are communicating with each other via the exchange (process 101), the subscriber C communicates with the subscriber A under the control of the interrupt control unit of the exchange. When an incoming call arrives (Process 1
02) To the subscriber A, a single ringing tone is transmitted from the exchange, that is, the same call waiting ring tone in the exchange (step 103), and the subscriber A has call waiting due to the call waiting ring tone. You can know. In this case, the call waiting ring tone transmitted to the call waiting subscriber A is the same for all subscribers even if the subscriber C changes, that is, regardless of who the subscriber is, It is the same for all subscribers, and subscriber A who has received a call waiting call cannot know from whom.

In addition, a single call waiting ringing tone is returned to the subscriber C from the exchange to the subscriber C who has performed the call waiting termination to the subscriber A (process 104), whereby the subscriber C is returned. Can know that a call waiting call is being made to the subscriber A. Again, the call waiting ring back to call waiting originating subscriber C is the same for all subscribers, regardless of who the subscriber is.
