    • The present invention relates to a handover method in CDMA mobile communication. A base station and a mobile station of the same establishes synchronization after the handover by correcting a discrepancy of a frame number on the base station side to reduce the processing load of the mobile station. Further, at the same time, optimumly performing a phase correction of the frame. In particular, a mobile station MS measures a time difference □ between a frame timing in an upstream traffic channel and a frame timing in a perch channel from a second base station BS2. Further, the second base station transmits the time difference □ to a base station in communication BS1. The base station BS1 sends the time difference □ and a frame number FN1 in the upstream traffic channel in communication to the base station BS2. The base station BS2 corrects the phase of the spread code at the reception of the upstream traffic channel based on the received time difference □ of the frame timing and the notified frame number FN1.
    • 本发明涉及CDMA移动通信中的切换方法。 基站和移动站在切换后通过校正基站侧的帧号的差异来建立移动台的处理负荷来建立同步。 此外,同时,最佳地执行帧的相位校正。 具体地说,移动台MS测量上行业务信道中的帧定时与来自第二基站BS2的导频信道中的帧定时之间的时间差。 此外,第二基站将通信BS1中的基站发送时差D. 基站BS1将通信中的上行业务信道中的时间差和帧号FN1发送给基站BS2。 基站BS2基于接收到的帧定时的时间差和通知的帧号FN1来校正上行业务信道的接收时的扩频码的相位。

    • A power supply unit includes a first power supply configured to supply electric power to a load using electric power supplied from an external power source; a second power supply configured to store the electric power supplied from the external power source and supply the stored electric power to the load; a no-power detecting unit configured to monitor a voltage of the external power source and detect no electric power from the external power source; and an output switching unit configured to switch the electric power to be supplied to the load to the electric power supplied from the second power supply when the no-power detecting unit detects no electric power. A first setting value that is a target output voltage of the first power supply is larger than a second setting value that is a target output voltage of the second power supply.
