Communications method, and communications apparatus and system

A communications method, comprising:

• obtaining, by a home device, media access control (MAC) address related information of one or more devices having a network connection function that are in a same network as the home device, wherein the MAC address related information is used by a server to determine a target account, the target account is one account of a plurality of accounts associated with the home device, each account of the plurality of accounts is respectively associated with voiceprint information of a different user, and the one or more devices having a wireless connection function comprise a terminal device on which the accounts associated with the home device are logged in;
• recognizing, by the server, voiceprint information of the user based on voice instruction of the user as the operation information;
• determining, by the server based on a pre-established correspondence between voiceprint information and each account, an account corresponding to voiceprint information that best matches the voiceprint information of the user as the target account;
• sending, by the home device, the MAC address related information to the server;
• and
• sending, by the home device, operation information to the server, wherein the operation information is used to indicate an operation performed by a user on the home device;
• wherein
• a terminal device on which the target account is logged in is a target terminal device, the target terminal device is a terminal device receiving a notification message sent by the server, the notification message comprises status information used to indicate a status of the home device, and the status of the home device is related to the operation information.

A server, the server comprising a processor and a transceiver;

• wherein the processor is configured to:
• receive operation information from a home device by using the transceiver module, wherein the operation information is used to indicate an operation performed by a user on the home device;
• determine a target account, wherein the target account is one account of a plurality of accounts associated with the home device and each account of the plurality of accounts is respectively associated with voiceprint information of a different user;
• recognize voiceprint information of the user based on voice instruction of the user as the operation information;
• determining, based on a pre-established correspondence between voiceprint information and each account, an account corresponding to voiceprint information that best matches the voiceprint information of the user as the target account;
• and
• send a notification message to a target terminal device by using the transceiver, wherein the notification message comprises status information used to indicate a status of the home device, the status of the home device is related to the operation information, and the target terminal device is a terminal device on which the target account is logged in.

A home device, comprising a processor and a communications interface, wherein the processor is configured to:

• obtain media access control (MAC) address related information of one or more devices having a network connection function that are in a same network as the home device, wherein the MAC address related information is used by a server to determine a target account, the target account is one account of a plurality of accounts associated with the home device, each account of the plurality of accounts is respectively associated with voiceprint information of a different user, and the one or more devices having a wireless connection function comprise a terminal device on which the plurality of accounts associated with the home device are logged in;
• recognize voiceprint information of the user based on voice instruction of the user as the operation information;
• determine based on a pre-established correspondence between voiceprint information and each account, an account corresponding to voiceprint information that best matches the voiceprint information of the user as the target account;
• send the MAC address related information to the server through the communications interface;
• and
• send operation information to the server through the communications interface, wherein the operation information is used to indicate an operation performed by a user on the home device;
• wherein
• a terminal device on which the target account is logged in is a target terminal device, the target terminal device is a terminal device receiving a notification message sent by the server, the notification message comprises status information used to indicate a status of the home device, and the status of the home device is related to the operation information.

A communications system, comprising a server, a home device, and one or more terminal devices, wherein the home device is configured to

• send operation information to the server, wherein the operation information is used to indicate an operation performed by a user on the home device;
• the server is configured to
• determine a target account, wherein the target account is one account of a plurality of accounts associated with the home device, each account of the plurality of accounts is respectively associated with voiceprint information of a different user, recognize, by the server, voiceprint information of the user based on voice instruction of the user as the operation information, and determine, by the server based on a pre-established correspondence between voiceprint information and each account, an account corresponding to voiceprint information that best matches the voiceprint information of the user as the target account;
• and
• a target terminal device in the one or more terminal devices is configured to:
• receive a notification message from the server, wherein the notification message comprises status information used to indicate a status of the home device, the status of the home device is related to the operation information, and the target terminal device is a terminal device that is in the one or more terminal devices and on which the target account is logged in.
