Apple feels your spam call pain. The company apparently filed a patent called "Detection of spoofed call information" that would enable an iPhone to check whether a call is legitimate. If it’s not, the phone would automatically either display a warning to the user or prevent call alerts, such as ringing and vibration. The patent was first spotted by Apple Insider.

　　苹果公司已经意识到用户对骚扰电话的抱怨。该公司申请了一项名为“检测欺骗来电信息”的专利，该专利可以让iPhone检查来电是否合法。如果属于骚扰电话，手机会自动向用户显示警告或阻止来电铃声和震动。这项专利最先由苹果内部人士提出。

　　How can a phone identify a spam or spoofed call? The patent makes clear that the phone would check against established, legitimate call parameters in order to determine the validity of a call that’s being connected. The phone would analyze the information being sent over the call, including network equipment identifiers, server identifiers and more.

　　那么，手机如何识别骚扰电话呢?专利明确规定，手机将根据已建立的合法通话参数进行检查，以确定来电的真实性。手机可以分析出骚扰来电发出的信息，包括网络设备标识符、服务器标识符等等。

　　Apple isn’t the only handset manufacturer working on this kind of technology. At Google’s event this week, the company introduced a Call Screen feature that utilizes Google Assistant to help weed out spam calls. Additionally, an update to the company’s phone app from earlier this year sends spam calls directly to voicemail.

　　苹果并不是唯一一家致力于研究此类技术的手机制造商。谷歌公司在本周的活动中推出了一项屏幕呼叫功能，利用谷歌助手来清除垃圾电话。此外，该公司今年早些时候对手机应用程序进行升级，可以将骚扰电话直接转移到语音信箱。

　　It’s important to note that Apple files many patents that it doesn’t actually do anything with. But with spam calls on the rise, and people getting more and more frustrated by them (how many of you actually answer phone calls from numbers you don’t recognize anymore?), having a feature like this on the iPhone could be incredibly useful.

　　值得注意的是，苹果公司申请了许多实际上并没有商业应用的专利。但随着骚扰电话数量的增加，人们对骚扰电话抱怨越来越多(你们中有多少人实际上接听了自己不认识的电话号码?)，在iPhone手机上安装这样的功能可能会非常有用。
