As is well known, when a caller attempts to make a phone call in a conventional mobile communication network, the switching subscriber of the called subscriber adopts a method in which a uniform ringback tone is heard to the caller. Such a conventional ringback tone method uses a uniformly identical tone. Since the caller cannot determine whether the caller has a wrong connection until the answer of the called party, there is also a problem that can not provide a variety of ringback tone replacement service to meet the characteristics of the user.

In order to solve this problem, recently, when a called subscriber selects and registers a specific sound source on a mobile communication network instead of the uniform ringback tone, the specific sound source registered at the caller's call can be provided as a ringback tone. The caller can determine whether there is a misconnection before the called party's response and provide various ringback tone replacement sounds that match the characteristics of the called party.

Recently, a mobile communication terminal having a SVD (Simultaneous Voice and Data) function capable of simultaneously performing data communication using a packet data communication network such as wireless Internet while making a voice call with the other party through a mobile communication network has been developed and applied. Through the mobile communication terminal having the SVD function, not only the video communication that the subscriber receives and reproduces the image data transmitted from the other party while making a voice call with the other party is possible at the same time, but also the packet data communication through the wireless Internet simultaneously. It becomes possible.

However, in the mobile communication system to which the mobile communication terminal with the SVD function is applied, data communication such as transmission / reception of image data is possible at the same time during a voice call with the other party, but a specific sound source is ringed as a subscriber-based ringback tone service. Even if a call is made to a predetermined called subscriber set as a backtone replacement tone, voice call and data communication can be simultaneously performed because the predetermined sound source can be received and reproduced by mutual message exchange between the calling exchange and the called exchange. The disadvantage is that the SVD function is not properly applied to the subscriber-based ringback tone service.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to attempt to make a call to a called subscriber who sets a specific sound source as a ringback tone substitute in a mobile communication terminal capable of voice call and data communication at the same time.
