Abstract: A call method is provided. In the call method, a first account is associated with a number of called party devices. A calling party device may call the number of called party devices by using the first account. When receiving calling, a called party device that is difficult to carry, such as a smart speaker or a smart television, may detect whether a distance to a smartwatch or a mobile phone having a same account is less than a distance threshold. If the distance is less than the distance threshold, the smart speaker or the smart television may output an incoming call prompt. If the distance is not less than the distance threshold, the smart speaker or the smart television ignores the received calling, and makes no response to the calling.
