Description

Method and system for auto-connect after call waiting service {Method and System for Providing Busy Call Connection Service}

The present invention relates to a call waiting service of a telephony communication system, and more particularly, provides a call waiting sound such as music to a caller until the caller ends the call when the caller is in a call and when the call is terminated, The present invention relates to a system and method for automatic connection service after waiting for a call to connect.

With the rapid development of computer, electronic and communication technologies, various wireless communication services using wireless networks have been provided. The most basic wireless communication service is a wireless voice call service that provides voice calls wirelessly between mobile terminal users regardless of time and place. In recent years, wireless Internet services that provide a communication service using the Internet through a wireless communication network have emerged while a user of a mobile communication terminal moves without restriction of a place. Therefore, the subscribers of the mobile communication service can freely move and talk with the other party anytime and anywhere using the wireless communication service, and also have information necessary for life, such as news, weather, sports, securities, and exchange rates, through the wireless Internet service. , Traffic information, etc. may be provided in various forms such as text, voice, and image.

Recently, a ring back tone (RBT) service or a so-called coloring RBT (CRBT: Coloring RBT) that allows a user to hear various sounds designated by a called subscriber of a mobile communication terminal as a call waiting tone from a mobile communication terminal or a general telephone of a calling party. ) The service is in the spotlight. This call waiting sound service is a service concept that provides the other party with the sound specified by the called party, and instead of the mechanical call waiting sound that occurs during the existing call, for example, a "pushing" sound, as well as the latest song or pop song, as well as the sound of birds and water. In addition, it is a service that allows you to use your own voice that you have recorded beforehand as a call waiting sound. According to the call waiting sound service, the other party may feel auditory satisfaction by listening to the sound of the sound source designated by the calling subscriber, instead of listening to the uniform and mechanical call waiting sound.

If the caller calls the called party, the called party hears the call waiting tone specified by the called party in the idle state when the called party is not talking to the other party, but the called party is able to call the other party. You will hear a busy tone.

In this case, the calling subscriber knows that the called subscriber is busy and hangs up and tries again or forgets.

A useful service that can solve the above disadvantages is a call waiting service. The call waiting service is a service that allows a caller to selectively switch a phone call between the other party and the caller when the called party comes from the caller while the called party is in the off-hook state with the other party.

However, during the call waiting service, the caller continues to hear only the ringing tone unless the caller switches the busy call to the caller's call. In this case, the caller misunderstands that the called party does not answer his or her own phone without knowing that the other party is on the phone.

Therefore, there is an urgent need for a new service that can solve the aforementioned inconveniences experienced by the calling subscriber when the called subscriber is busy.

Therefore, the present invention has been invented based on the above-described needs, and an object of the present invention is to provide a call waiting sound to the caller with a guide message until the called party ends the call when the called party is busy and to the caller at the end of the call. It is to provide an automatic connection system and method after waiting during a call to automatically connect a call.
