    • PURPOSE: A backward traffic frame selection method under a soft handoff of a CDMA mobile communication is provided to improve a speech quality by selecting a traffic frame having a good quality among traffic frames transmitted through different base station in the time of a soft hand-off. CONSTITUTION: A base station A receives a traffic frame N(bad frame) from a mobile station, and transmits the traffic frame N to a control station(21). A base station B receives a traffic frame N'(good frame), and transmits the control station(22). The control station selector stores the traffic frame N without transmitting the traffic frame N to a transcoder(23). The traffic frame N' is transmitted to the control station selector(24). The control station selector(24) compares the traffic frame N and the traffic frame N', and selects the traffic frame N'(good frame)(25).
    • 目的:提供CDMA移动通信软切换下的后向业务帧选择方法,通过在软越区切换时选择通过不同基站发送的业务帧中具有良好质量的业务帧来提高语音质量 。 构成:基站A从移动台接收业务帧N(坏帧),并将业务帧N发送到控制站(21)。 基站B接收业务帧N'(良好帧),并发送控制站(22)。 控制站选择器存储业务帧N而不将业务帧N发送到代码转换器(23)。 业务帧N'被发送到控制站选择器(24)。 控制站选择器(24)比较业务帧N和业务帧N',并选择业务帧N'(良好帧)(25)。
