Abstract: This application provides a voice interaction method. For a plurality of electronic devices equipped with a same voice assistant, a voice assistant of only one electronic device is in a working mode, and voice assistants of other electronic devices are all in a silent mode. When a user gives a voice for the voice assistant, the other electronic devices whose voice assistants are in the silent mode do not respond to a first instruction triggered by the voice of the user, only the electronic device whose voice assistant is in the working mode sends, according to the first instruction triggered by the voice of the user, a second instruction to an electronic device that is in the plurality of electronic devices and that has a capability of executing a task requested by the user, and the electronic device that receives the second instruction executes the task requested by the user.

Abstract: A mobile terminal control method includes receiving N direction-finding signals that are respectively sent by a multiple-antenna node at N moments, where the multiple-antenna node is located in an indoor-outdoor critical area. The method includes obtaining N pieces of location relationship information between a mobile terminal and the multiple-antenna node at the N moments according to the N direction-finding signals, where the N moments and the N pieces of location relationship information are in a one-to-one correspondence. The method includes determining location relationship change information between the mobile terminal and the multiple-antenna node according to at least M of the N pieces of location relationship information, where 2≤M≤N. The method includes controlling the mobile terminal by matching the location relationship change information and according to the location relationship change information.

Abstract: The present disclosure relates to the field of short-distance wireless communications technologies, and in particular, to a method and system for obtaining location information of a target object, and an apparatus. In a solution of obtaining location information of a target object in the solutions, at least one second user is selected from a user relationship chain of a first user, and the location information of the target object is obtained by using a second terminal related to the second user. In another solution of obtaining location information of a target object, the location information of the target object is obtained by using a second terminal whose distance to a location represented by first location information is less than or equal to a preset distance.
