    摘要: This invention relates to apparatus and a method for use in conjunction with a service wherein a called telephone customer (111) receives a display (113) of the number of a calling telephone customer (101). In conjunction with this service, customers are offered a class of service and/or an option to dial a privacy request wherein their telephone number will not be displayed to the called telephone customer. In accordance with this invention, the customers are offered a class of service wherein they will receive calls only from telephone customers willing to have their telephone number displayed. If a call is made from a caller who does not wish to have his number displayed to a called customer who will not accept calls from customers unwilling to identify themselves, the caller is given a special announcement; in response to this announcement if the caller keys a special privacy override code then the call is completed with the caller's number displayed. Law enforcement agencies may be provided with a class of service which allows them to obtain a caller's number even when the caller has invoked privacy. Advantageously, such an arrangement protects telephone customers from receiving harassing calls, protects the privacy of those customers who normally do not wish to have their telephone number identified to the called customer, and permits calls to be completed between such customers.

    摘要翻译: 本发明涉及一种与服务结合使用的装置和方法,其中被叫电话客户接收到呼叫电话客户号码的显示。 结合这项服务,客户可以提供一类服务和/或拨打隐私请求的选项,其中他们的电话号码不会显示给被叫电话客户。 根据本发明,客户被提供一类服务,其中他们将仅接收来自愿意显示其电话号码的电话客户的呼叫。 如果来电者不希望将号码显示给被叫客户,不接受不愿意识别客户的电话,则给予来电者特别公告; 响应于该通知,如果呼叫者键入特殊的隐私覆盖代码,则呼叫完成,显示呼叫者号码。 执法机构可能会获得一类服务,即使在来电者已经调用隐私的情况下,他们也可以获得一个来电者的电话号码。 有利的是,这样的布置保护电话客户不受到骚扰的呼叫,保护那些通常不希望将其电话号码识别给被叫的客户的客户的隐私,并允许在这些客户之间完成呼叫。
