摘要： A radio telephone system includes a base station and a plurality of mobile stations. The base station transmits echo-back request signals to the mobile stations in turn. When the mobile station fails to transmit an echo-back response signal, the base station determines that the non-responsive mobile station is outside a radio zone of the base station, and deletes the corresponding data from a storage section thereof. Further, the base station is capable of changing its transmission power level so as to change a size of the radio zone correspondingly. Specifically, the base station monitors a range of presence of the mobile stations within the radio zone, and changes its transmission power level depending on such a range. For example, when such a range spreads over the radio zone, the base station may control its transmission power level to be maximum. On the other hand, when such a range is only around the base station, the base station may control its transmission power level to be minimum.
摘要翻译：无线电话系统包括基站和多个移动台。基站依次向移动台发送回波请求信号。当移动台不能发送回波响应信号时，基站确定无响应移动台在基站的无线电区域之外，并从其存储部分删除相应的数据。此外，基站能够改变其发送功率电平，从而相应地改变无线电区域的大小。具体地，基站监视无线电区域内的移动台的存在范围，并且根据这样的范围改变其发送功率电平。例如，当这样的范围在无线电区域上扩展时，基站可以将其发送功率电平控制为最大。另一方面，当这样的范围仅在基站周围时，基站可以将其发送功率电平控制为最小。

摘要： The efficiency of multiplication in secure function computation is increased to make the secret function computation faster than before. Three or more computing apparatuses cooperate to generate a secret value of a random number, perform secure function computation for secret values of arbitrary values by using a function including addition and multiplication to compute concealed function values, and compute a secret value. If the secret value is [0], a concealed function value is output; otherwise, information indicating that tampering has been detected is output.
