    • A mobile communication terminal holds a frequency cancellation list that is information related to cells that cannot be connected, and controls execution/non-execution (frequency cancellation) of the cell search according to the content of the cancellation list. In a case where a frequency is not assigned in a unified manner (when a frequency is assigned to different communication providers in some cells), a frequency cancellation time is set shorter than a case where the frequency is assigned in a unified manner. For example, a frequency f3 is rejected in a cell represented by “another” surrounded by a broken line when the mobile communication terminal moves from an area A to an area B. When the mobile communication terminal further moves to an area C, the frequency cancellation process initiated in the area B terminates. This is because a short frequency cancellation time is set. Therefore, the frequency cancellation time expires while the mobile communication terminal is moving from the area B to the area C. The frequency cancellation terminates, so as to be connectable in the area C of the frequency f3.
    • 移动通信终端保持与无法连接的小区相关的信息的频率抵消列表,并且根据取消列表的内容来控制小区搜索的执行/不执行(频率消除)。 在没有以统一的方式分配频率的情况下(频率在一些小区中被分配给不同的通信提供者)时,将频率消除时间设置为比以统一方式分配频率的情况更短。 例如,当移动通信终端从区域A移动到区域B时,在由虚线包围的“另一”表示的小区中,频率f3被拒绝。当移动通信终端进一步移动到区域C时,频率 在区域B中启动的取消过程终止。 这是因为设定了短的频率取消时间。 因此,当移动通信终端从区域B移动到区域C时,频率消除时间到期。频率消除终止,以便可以在频率f3的区域C中连接。

    • A cell search control that can save power consumption at a mobile device and perform an appropriate in-service area determination is provided. The mobile device according to the present invention includes: a cell search execution unit (120) for detecting a synchronization channel from a base station to perform cell search; a signal reception determination unit (130) for comparing a measurement X of the signal from the base station with a system information reception threshold A and determining whether or not to receive a system information from the base station; and an in-service area determination unit (170) for comparing the measurement X with a minimum required quality level B contained in the system information and determining whether or not to enter into an in-service area state with the base station. Depending on the result of the in-service area determination unit, the reception threshold A or a waiting time for the cell search may be adjusted, or the base station may be excluded from the cell search. Thus, the power consumption at the mobile device can be saved, and an appropriate in-service area determination can be made even when the minimum required quality level B has been changed.
    • 提供了可以在移动设备上节省功耗并执行适当的在役区域确定的小区搜索控制。 根据本发明的移动设备包括:小区搜索执行单元,用于检测来自基站的同步信道以执行小区搜索; 用于将来自基站的信号的测量X与系统信息接收阈值A进行比较并确定是否从基站接收系统信息的信号接收确定单元(130) 以及用于将测量X与包含在系统信息中的最小所需质量等级B进行比较并确定是否进入与基站的在役区域状态的在役区域确定单元(170)。 根据使用区域确定单元的结果,可以调整接收阈值A或小区搜索的等待时间,或者可以从小区搜索中排除基站。 因此,可以节省移动设备的功耗,即使当最小要求质量等级B已经改变时,也可以进行适当的在役区域确定。
