According to the description, this is about a method and device for blocking incoming calls, involving the field of communications. The patent “solves the problem that when a marked unfamiliar phone calls in, the mobile phone still reminds the user that the user needs to hang up or answer, which still causes interference to the user.”

The method includes: receiving an incoming call and obtaining the phone identification of the incoming call; judging whether the incoming call is a malicious incoming call according to the incoming call’s phone identification. When it is determined that the incoming call is a malicious incoming call, the feature alerts the user and blocks phones marked as malicious phone identifiers.

We can’t say if Xiaomi will be releasing this feature soon but it will be interesting to see this in the near future.
