Apparatus and method for providing call waiting service {APPARATUS AND METHOD FOR PROVIDING CALL WAITING SERVICE}

The present invention relates to an apparatus and method for providing a call waiting service, and more particularly, to an apparatus and method for providing a service to a third party when a subscriber requests a call from a third party while the subscriber is in a call.

In general, in a mobile communication network, when a caller and a called party are in a call, when the third party requests a call from the calling caller or the called party, the corresponding exchange sends a ringback tone to the third party indicating that the call is in progress. This ringback tone is a uniform machine sound, which can be boring to the listening third party. In addition, the mobile communication network provides an automatic answering service for automatically answering a voice call to a third party who receives a busy signal as a call waiting service instead of a ringback tone of a machine tone.

However, since both the ringback tone and the answering service only perform a function of notifying the third party that the call is busy, the third party still has the inconvenience of ending the call and attempting to call again. In particular, if the call between the caller and the called party becomes long, the number of times that the call must be terminated and the call is attempted again increases. This leads to an increase in incomplete calls and eventually a third subscriber to abandon the call, which may result in a decrease in call quality.

In addition, the call waiting service generally means that when a user attempts to make a call while the user is busy, the busy user can know that there is a call request from a third party, but the third party is the user who is busy. Status information is unknown. That is, the call waiting service does not provide a service for notifying a third party that the user is busy.

The technical problem to be solved by the present invention is to reduce the incomplete call occurring from the user who received the busy signal and the apparatus for providing a call waiting service that can provide the user with the status information of the subscriber requesting the call; To provide a way.

According to this method, (a) transmitting the advertisement information to the third terminal during the waiting time before the call is connected with the first terminal; And (b) stopping the transmission of advertisement information to the third terminal and setting up a communication channel between the third terminal and the first terminal when the call channel between the first and second terminals is released. do.

According to another embodiment of the present invention, there is provided a call waiting service providing apparatus including a communication unit and a service providing unit. The communication unit receives the busy state information of the first terminal when a call connection is requested from the third terminal to the first terminal while the communication channel between the first and second terminals is set. The service providing unit provides the third terminal with advertisement information provided from the advertisement server during the waiting time until the call is connected with the first terminal according to the reception of the busy state information of the first terminal.

According to an embodiment of the present invention, when a subscriber is in a call, the third party provides an advertisement service when a call request is made from the third party to the third party, so that the third party may use the advertisement service until the subscriber ends the call. Can be provided. This can reduce incomplete calls from third parties. And the third party may know that the subscriber is busy, and may decide whether to wait while receiving the advertisement service.
