    • A method and device for preventing fraud in special service calls from an international origin point to a domestic terminating point through a long-distance telecommunications system is described. In the system and method, a Screening for International Calls database is added to the Integrated Services Network (ISN) platform. The records in the Screening for International Calls database are keyed by the country code and contain a field for blocked terminating regions. When an international call is made, the record corresponding to the international origin point is retrieved from the Screening for International Calls database. This record is checked to determine if there are terminating regions indicated in the blocked exchange field. If there are no terminating regions indicated in the blocked exchange field, call processing continues. If there are terminating regions indicated in the blocked exchange field, the terminating regions in the blocked exchange field are checked against the terminating point of the call. If the terminating point of the call is within the terminating region, the call is blocked.
    • 描述了通过远程电信系统防止从国际起点到家庭终点的特殊业务呼叫中的欺诈的方法和设备。 在系统和方法中,将国际呼叫筛选数据库添加到综合业务网络(ISN)平台。 国际电话筛选数据库中的记录由国家代码键入,并包含一个封闭终止区域的字段。 当进行国际电话时,从国际呼叫数据库检索对应于国际起点的记录。 检查该记录以确定是否在阻塞的交换字段中指示终止区域。 如果在阻塞的交换字段中没有指示终止区域,则继续呼叫处理。 如果在阻塞的交换字段中指示了终止区域,则阻止交换字段中的终止区域被针对呼叫的终止点进行检查。 如果呼叫的终止点在终止区域内,则呼叫被阻止。

    • The invention concerns a device for transmitting to a monitoring system attempts at fraud on at least one payphone (3). A control module placed on the telephone line (1) comprises means (11) for generating a random number, means (16) for transmitting said random number to said payphone (3), and means for authenticating the payphone (3). The invention is characterised in that the means (11) generating a random number are capable of generating a specific random number, representing an anomaly in the authentication, the payphone (3) being provided with means for identifying said specific type so as to transmit to the monitoring system (4) an anomaly information.
    • 本发明涉及一种用于向至少一个公共电话(3)发送欺诈尝试的监控系统(4)的设备。 放置在电话线(1)上的控制模块(10)包括用于产生随机数的装置(11),用于将所述随机数发送到所述公用电话(3)的装置(16),以及用于 公共电话(3)的认证。 本发明的特征在于,用于产生随机数的所述装置(11)能够产生特定随机数,指示所述验证的异常的,公共电话(3)被提供有用于 识别所述特定类型以便向监视系统(4)发送异常信息。
