摘要： Disclosed is a method, a system and a mobile communication terminal for providing a ringback tone alternative (hereinafter referred to as "RBT-alternative") service, and more particularly to a method, a system and a mobile communication terminal for providing a RBT-alternative service by bit-streaming a specific preset tone as a replacement for a regular RBT in real time, in which, in order to adaptively apply various audio codecs associated with service types and thus provide a RBT-alternative having an improved quality, a signaling message controlling the mobile communication terminal to switch over its basic codec to an audio codec is transmitted to the mobile communication terminal to thereby enable the mobile communication terminal to reproduce a sound source by using the audio codec when the sound source using the audio codec is set as RBT- alternative, and a signaling message controlling the mobile communication terminal to switch over its basic codec to a voice codec again is transmitted to the mobile communication terminal to thereby enable the mobile communication terminal to perform voice communication by using the voice codec when the RBT-alternative service is terminated.
摘要翻译：公开了一种用于提供回铃音替代（以下称为“RBT替代”）服务的方法，系统和移动通信终端，更具体地涉及一种用于提供RBT-替换的方法，系统和移动通信终端，通过将特定预设音调进行比特流的替代服务作为实时的常规RBT的替代，其中为了自适应地应用与服务类型相关联的各种音频编解码器，并且因此提供具有改进的质量的RBT替代，信令控制移动通信终端将其基本编解码器切换为音频编解码器的消息被发送到移动通信终端，从而使得当使用音频编解码器的声源被设置时，通过使用音频编解码器使得移动通信终端能够再现声源作为RBT替代，并且控制移动通信终端再次将其基本编解码器切换到语音编解码器的信令消息是t 发送到移动通信终端，从而能够使移动通信终端在RBT替代服务终止时使用语音编解码器进行语音通信。
