TECHNICAL FIELD

The embodiments relate to the communications field, and in particular, to a communications method, and a communications apparatus and system.

BACKGROUND

As shown in FIG. 1, an existing smart home system includes a smart home cloud, a smart home application (APP) installed on a terminal device, and smart home devices (for example, an air conditioner, a refrigerator, and a rice cooker). Generally, a plurality of different accounts may be logged in on a plurality of smart home APPs to perform an operation on a same smart home device. When an account is logged in on a smart home APP to perform an operation on a smart home device, the smart home cloud only needs to push status information of the smart home device to the account.

However, currently, when a user directly performs an operation on a smart home device, the device reports status information to the smart home cloud. In this case, the smart home cloud does not know an account the status information should be pushed to. Consequently, the smart home cloud pushes the status information to all accounts that have subscribed to the status information of the device, or pushes, by default, the status information to all accounts that have been bound to the device. As a result, some unwanted information is inevitably received by some accounts, and this deteriorates user experience.

In addition, for ease of clear description of the solutions in the embodiments, terms such as “first” and “second” are used in the embodiments to distinguish between same items having a basically same function and effect or similar items. A person of ordinary skill in the art can understand that the terms such as “first” and “second” are not intended to limit a quantity and an execution sequence, and that the terms such as “first” and “second” are unnecessarily limited to be different.

FIG. 2 shows a smart home system 10 according to an embodiment. The smart home system 10 includes a server (which may also be referred to as a smart home cloud) 20, a target terminal device 30, and a home device 40. A smart home APP is installed on the target terminal device 30.

The smart home system 10 shown in FIG. 2 is used as an example. In this embodiment, in a possible implementation, the home device sends operation information to the server, where the operation information is used to indicate an operation performed by a user on the home device. After receiving the operation information from the home device, the server determines a target account, where the target account is one of accounts associated with the home device; and sends a notification message to the target terminal device on which the target account is logged in, where the notification message includes 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. In this embodiment, when the user controls the home device, the server can determine the target account, and send the notification message including the status information of the home device to the target terminal device on which the target account is logged in. This prevents unwanted information from being received by an account other than the target account, thereby enhancing user experience.

It should be noted that interaction between the server and the terminal device in this embodiment can be understood as interaction between the server and an account logged in on the smart home APP running on the terminal device. All the accounts in this embodiment are accounts that are associated with the home device and that can be logged in on the smart home APP running on the terminal device. The smart home APP may be used to control a home device that is connected to a network. A unified description is provided herein, and is not repeated in the following embodiments.

FIG. 3 is a schematic structural diagram of the communications device 20 according to an embodiment. The communications device 20 includes one or more processors 201, a communications bus 202, and at least one communications interface (that a communications interface 204 and one processor 201 are included in FIG. 3 is merely used as an example for description), and may optionally further include a memory 203.

The processor 201 may be a general-purpose central processing unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits configured to control execution of programs in the solutions in the embodiments.

The communications bus 202 may be a peripheral component interconnect (PCI) bus, an extended industry standard architecture (EISA) bus, and or the like. The bus may be classified into an address bus, a data bus, a control bus, and the like. For ease of representation, only one thick line is used to represent the bus in FIG. 3, but this does not mean that there is only one bus or only one type of bus. The communications bus 202 is configured to connect different components in the communications device 20, so that the different components can communicate with each other.

The communications interface 204 may be a transceiver module, and is configured to communicate with another device or a communications network, such as an Ethernet network, a radio access network (RAN), or a wireless local area network (WLAN). For example, the transceiver module may be an apparatus such as a transceiver.

During specific implementation, in an embodiment, the communications device 20 may further include an output device 205 and an input device 206. The output device 205 communicates with the processor 201, and may display information in a plurality of manners. For example, the output device 205 may be a liquid crystal display (LCD), a light emitting diode (LED) display device, a cathode ray tube (CRT) display device, or a projector. The input device 206 communicates with the processor 201, and may receive a user input in a plurality of manners. For example, the input device 206 may be a mouse, a keyboard, a touchscreen device, or a sensing device.

Currently, when a user directly performs an operation on a smart home device, the device reports status information to the smart home cloud, and in this case, the smart home cloud does not know which account the status information should be pushed to. Consequently, the smart home cloud pushes the status information to all accounts that have subscribed to the status information of the device, or pushes, by default, the status information to all accounts that have been bound to the device. As a result, some unwanted information is inevitably received by some accounts, deteriorating user experience. In view of this, an embodiment provides a communications method. In the communications method, a home device sends operation information to a server, where the operation information is used to indicate an operation performed by a user on the home device. After receiving the operation information from the home device, the server determines a target account, where the target account is one of accounts associated with the home device; and sends a notification message to a target terminal device on which the target account is logged in, where the notification message includes 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. In this embodiment, when the user controls the home device, the server can determine the target account, and send the notification message including the status information of the home device to the target terminal device on which the target account is logged in. This prevents unwanted information from being received by an account other than the target account, thereby enhancing user experience. With reference to the smart home system 10 shown in FIG. 2, the following details, by using specific embodiments, the communications methods provided in the embodiments.

It should be noted that names of messages between devices, names of parameters in the messages, or other names in the following embodiments are merely examples, and the names thereof may be other names during specific implementation. This is not limited in this embodiment.

In a possible implementation, as shown in FIG. 4, a communications method provided in the embodiments includes the following steps.

S401: A home device sends operation information to a server. Correspondingly, the server receives the operation information from the home device.

The operation information is used to indicate an operation performed by a user on the home device.

Optionally, in this embodiment, when the user directly performs an operation on the home device, the home device may send the operation information to the server. It should be noted that, that the user directly performs an operation on the home device means that the user controls the home device not by using a smart home APP. For example, that the user directly performs an operation on the home device may be that the user controls the home device by pressing keys on the home device. For example, assuming that the home device is an air conditioner shown in FIG. 5, after the user presses a “temperature+” button on the air conditioner, the home device sends operation information to the server. Content of the operation information may include, for example, “the user increases a specified temperature, and a current specified temperature is 21 degrees (that pressing “temperature+” once means correspondingly increasing one degree is used as an example). Alternatively, for example, assuming that the home device is a rice cooker, after the user presses a function key to adjust a mode to “cooking rice” for 30 minutes, the home device sends operation information to the server. Content of the operation information may include, for example, “the mode set by the user is ‘cooking rice’ for 30 minutes, and start time of the mode is 12:00″. After receiving the operation information, the server may determine a target account by using the following steps S402 to S404. The target account is one of accounts associated with the home device.

It should be noted that after receiving the operation information, the server can immediately determine the target account. For example, after receiving the operation information sent by the air conditioner shown in FIG. 5, the server immediately determines the target account to which status information of the air conditioner needs to be pushed. Alternatively, the server may determine the target account at a specific time point after receiving the operation information, where the specific time point may be determined based on the content of the operation information. For example, after receiving the operation information sent by the rice cooker, the server may determine the specific time point to be 12:30.

Optionally, in this embodiment, when the user directly performs operations on the home device for a plurality of consecutive times (where a time interval between a current operation and a previous operation does not exceed a preset time), the home device may send operation information to the server only once. The operation information includes information about the home device after the last operation in the current round of consecutive operations of the user. For example, when the user presses the “temperature+” button on an air conditioner panel shown in FIG. 5 for three consecutive times (where a time interval between a current operation and a previous operation does not exceed a preset time), the air conditioner sends operation information to the server only once. Content of the operation information may include, for example, “the user increases a specified temperature, and a current specified temperature is 23 degrees (that pressing “temperature+” once means correspondingly increasing one degree is used as an example). When the user performs operations on the home device for a plurality of consecutive times, the home device needs to send operation information to the server only once, and therefore power consumption of the home device can be reduced. Correspondingly, the server needs to receive the operation information only once, and therefore power consumption of the server is also reduced.

S402: The server obtains GPS location information of one or more terminal devices.

The one or more terminal devices are logged in by the accounts associated with the home device. It should be noted that, in this embodiment, when an account associated with the home device is logged in on a terminal device, it is considered that a status of the account is an online state. A unified description is provided herein, and is not repeated in the following embodiments.

Optionally, in this embodiment, the server may obtain the GPS location information of the one or more terminal devices in the following manner:

The server sends a GPS location information query message to the one or more terminal devices, and correspondingly the one or more terminal devices receive the GPS location query message from the server. The one or more terminal devices each send GPS location information to the server, and correspondingly the server receives the GPS location information from the one or more terminal devices. Certainly, the server may alternatively obtain the GPS location information of the one or more terminal devices in another manner. This is not limited in this embodiment.

It should be noted that the one or more terminal devices include the foregoing target terminal device. For example, when there is only one terminal device, the terminal device and the target terminal device are a same terminal device. When there are a plurality of terminal devices, the target terminal device may be any one of the plurality of terminal devices.

S403: The server obtains GPS location information of the home device.

When the home device is installed for the first time or a network environment changes, for example, when a home wireless fidelity (Wi-Fi) network changes because of relocation, network access and registration operations of the home device are triggered. Network access and registration of the home device need to be completed by logging in to an account associated with the home device, on a smart home APP running on a terminal device, and the terminal device and the home device need to be located in a same network. Therefore, when the home device performs network access and registration, locations of the terminal device and the home device are close to each other. In this case, it may be considered that GPS location information that is of the terminal device and that is present when the home device performs network access is the GPS location information of the home device. The terminal device may obtain the GPS location information of the terminal device, and send the GPS location information of the terminal device as the GPS location information of the home device to the server.

Based on this, the server may obtain the GPS location information of the home device in the following manner:

The server receives network access GPS location information, where the network access GPS location information is GPS location information that is of a network access terminal device and that is present when the home device performs network access by using the network access terminal device, and the network access terminal device is a terminal device on which the account used by the home device to perform network access is logged in; and the server determines the network access GPS location information as the GPS location information of the home device.

Optionally, in this embodiment, each time the network environment changes, the terminal device may send, to the server, GPS location information that is of the home device and that is present after network access and registration are re-performed. After receiving the GPS location information, the server updates the GPS location information of the home device. Further, because all home devices in a house may be located in a same network, each time after the server receives the GPS location information of the home device, the server may use the GPS location information as GPS location information of all the home devices in the house. This avoids that the server separately obtains GPS location information of the home devices in the house, thereby reducing power consumption of the server.

The network herein may be a wireless network such as a Wi-Fi network, or may be a network in another form. This is not limited in this embodiment.

S404: The server determines, as the target account, an account corresponding to GPS location information that is in the GPS location information of the one or more terminal devices and that is closest to the GPS location of the home device.

Optionally, in this embodiment, the server may compare the GPS location information of the one or more terminal devices with the GPS location information of the home device to determine the GPS location information that is in the GPS location information of the one or more terminal devices and that is closest to the GPS location of the home device, and determine, as the target account, the account corresponding to the GPS location information closest to the GPS location of the home device.

S405: The server sends a notification message to the target terminal device. Correspondingly, the target terminal device receives the notification message from the server.

As described above, in this embodiment, that the terminal device on which the target account is logged in is the target terminal device is used as an example for description. The notification message includes status information used to indicate a status of the home device, and the status information of the home device is related to the operation information. For example, the user currently controls the air conditioner shown in FIG. 5. The status information of the home device may be “a current specified temperature is 21 degrees”, and an interface displayed after the target terminal device receives the notification message may be shown in FIG. 6. Alternatively, for example, the user currently controls a rice cooker. The status information of the home device may be “rice cooking ends at 12:30”.

Optionally, in this embodiment, after determining the target account, the server can immediately send the notification message to the target terminal device on which the target account is logged in.

Optionally, in this embodiment, after receiving the notification message from the server, the target terminal device may determine the status of the home device based on the notification message, to perform a subsequent operation. For example, the notification message received by the target terminal device includes “rice cooking ends at 12:30”. The target terminal device may determine whether current time is later than 12:30. If the current time is later than 12:30 (for example, the current time is 12:31), the target terminal device may notify, in a vibration or ringing manner, the user that rice cooking has ended. Alternatively, the target terminal device may control, by using the target account logged in on the target terminal device, the rice cooker to be powered off or enter a heat preservation mode.

It should be noted that, in this embodiment, there is no definite sequence between step S401 and step S403. Step S401 may be performed before step S403, step S403 may be performed before step S401, or step S401 and step S403 may be performed simultaneously. This is not limited in this embodiment.

In the communications method provided in this embodiment, the home device sends the operation information to the server, where the operation information is used to indicate the operation performed by the user on the home device. After receiving the operation information from the home device, the server determines, as the target account based on the GPS location information of the one or more online accounts and the GPS location information of the home device, the account corresponding to the GPS location information closest to the GPS location of the home device, and sends the notification message to the target terminal device on which the account is logged in. The notification message includes the status information used to indicate the status of the home device. In this embodiment, when the user controls the home device, the server can determine the target account, and send the notification message including the status information of the home device to the terminal device on which the target account is logged in. This prevents unwanted information from being received by an account other than the target account, thereby enhancing user experience.

In another possible implementation, as shown in FIG. 7, a communications method provided in the embodiments includes the following steps.

S701: A server establishes a correspondence between an account associated with a home device and voiceprint information of a user.

Optionally, in this embodiment, the user may be a user who uses the home device, for example, all family members in a family.

Optionally, in this embodiment, the server may establish the correspondence between an account associated with the home device and voiceprint information of a user in the following manner:

The server receives information that is about an account associated with the home device and that comes from one or more terminal devices and voice information of a user associated with the account. The one or more terminal devices are terminal devices on which the accounts associated with the home device are logged in. It should be noted that the one or more terminal devices include the foregoing target terminal device. For example, when there is only one terminal device, the terminal device and the target terminal device are a same terminal device. When there are a plurality of terminal devices, the target terminal device may be any one of the plurality of terminal devices.

The server performs voiceprint recognition on the voice information of the user associated with the accounts associated with the home device, and determines voiceprint information of the user associated with the accounts associated with the home device, where the voice information of the user may be a segment of voice. The server may recognize the voiceprint information based on the voice. The voiceprint information may include information such as a timbre.

The server establishes the correspondence between an account associated with the home device and voiceprint information of a user. For example, the correspondence, established by the server, between an account associated with the home device and voiceprint information of a user may be listed in Table 1.

Optionally, in this embodiment, when an account associated with the home device is registered, the one or more terminal devices may prompt a user associated with the account to input voice information and send information about the account and the voice information of the user to the server. Alternatively, after an account associated with the home device is logged in, the one or more terminal devices may prompt a user associated with the account to input voice information, and send information about the account and the voice information of the user to the server. Alternatively, the one or more terminal devices may send an account associated with the home device and voice information of a user associated with the account to the server at another moment. This is not limited in this embodiment.

TABLE 1 Information about an account Voiceprint information of a user associated with the account Account 1 Voiceprint 1 Account 2 Voiceprint 2 Account 3 Voiceprint 3 Account 4 Voiceprint 4

S702: The home device sends operation information to the server, where the operation information includes a voice instruction of a user who currently controls the home device. Correspondingly, the server receives the operation information from the home device.

The operation information is used to indicate an operation performed by the user on the home device.

Optionally, in this embodiment, for the home device having a voice recognition capability, the user may perform voice control on the home device. After receiving the voice instruction of the user, the home device may send the operation information to the server, where the operation information may include the voice instruction of the user. For example, it is assumed that an air conditioner shown in FIG. 8 has a voice recognition capability, and a user may perform voice control on the air conditioner. For example, the user sends a voice instruction “adjusting a temperature to 21 degrees” to the home device, and the home device sends operation information to the server after receiving the voice instruction. Content of the operation information may include, for example, “the voice instruction of the user is: adjusting the temperature to 21 degrees; and a current status is: the specified temperature is 21 degrees”. Alternatively, for example, it is assumed that the home device is a rice cooker. A user may send a voice instruction “setting a mode to ‘cooking rice’ for 30 minutes” to the home device, and the home device sends operation information to the server after receiving the voice instruction. Content of the operation information may include, for example, “the voice instruction of the user is: adjusting the mode to ‘cooking rice’ for 30 minutes; and start time of the mode is 12:00″. After receiving the operation information, the server may determine a target account by using the following steps S703 and S704. The target account is one of accounts associated with the home device.

S703: The server recognizes voiceprint information of the user based on the voice instruction of the user in the operation information.

After receiving the operation information, the server may recognize the voiceprint information of the user based on the voice instruction of the user included in the operation information.

S704: The server determines the target account based on the correspondence between voiceprint information and an account of a user.

The server may determine, based on the pre-established correspondence between voiceprint information and an account, an account corresponding to voiceprint information that best matches the voiceprint information of the user as the target account.

S705: The server sends a notification message to the target terminal device. Correspondingly, the target terminal device receives the notification message from the server.

As described above, in this embodiment, that the terminal device on which the target account is logged in is the target terminal device is used as an example for description. The notification message includes status information used to indicate a status of the home device, and the status of the home device is related to the operation information. For example, the user currently controls the air conditioner shown in FIG. 8. The status information of the home device may be “a current specified temperature is 21 degrees”, and an interface displayed after the target terminal device receives the notification message may be shown in FIG. 6. Alternatively, for example, the user currently controls a rice cooker. The status information of the home device may be “rice cooking ends at 12:30”.

Optionally, in this embodiment, after determining the target account, the server can immediately send the notification message to the target terminal device on which the target account is logged in.

Optionally, in this embodiment, after receiving the notification message from the server, the target terminal device may determine the status of the home device based on the notification message, to perform a subsequent operation. For example, the notification message received by the target terminal device includes “rice cooking ends at 12:30”. The target terminal device may determine whether current time is later than 12:30. If the current time is later than 12:30 (for example, the current time is 12:31), the target terminal device may notify, in a vibration or ringing manner, the user that rice cooking has ended. Alternatively, the target terminal device may control, by using the target account logged in on the target terminal device, the rice cooker to be powered off or enter a heat preservation mode.

It should be noted that, in this embodiment, there is no definite sequence between step S701 and step S702. Step S701 may be performed before step S702, step S702 may be performed before step S701, or step S701 and step S702 may be performed simultaneously. This is not limited in this embodiment.

In the communications method provided in this embodiment, the home device sends the operation information to the server, where the operation information is used to indicate the operation performed by the user on the home device. After receiving the operation information from the home device, the server determines, as the target account based on the correspondence between voiceprint information of a user and an account of the user, an account corresponding to voiceprint information that best matches the voiceprint information recognized based on the voice instruction of the user, and sends the notification message to the target terminal device on which the target account is logged in. The notification message includes the status information used to indicate the status of the home device. In this embodiment, when the user controls the home device, the server can determine the target account, and send the notification message including the status information of the home device to the terminal device on which the target account is logged in. This prevents unwanted information from being received by an account other than the target account, thereby enhancing user experience.

In still another possible implementation, as shown in FIG. 9, a communications method provided in the embodiments includes the following steps.

S901: A server establishes a correspondence between an account associated with a home device and a MAC address of a terminal device.

The terminal device is a terminal device on which the accounts associated with the home device are logged in.

It should be noted that step S901 is an optional step, and the server may not perform step S901.

Optionally, in this embodiment, the server may establish the correspondence between an account associated with the home device and a MAC address of a terminal device in the following manner:

The server receives a MAC address from each of one or more terminal devices and an account corresponding to the MAC address of the terminal device. It should be noted that the account corresponding to the MAC address of the terminal device can be understood as an account registered with or logged in on the terminal device. The one or more terminal devices include the foregoing target terminal device. For example, when there is only one terminal device, the terminal device and the target terminal device are a same terminal device. When there are a plurality of terminal devices, the target terminal device may be any one of the plurality of terminal devices.

The server establishes the correspondence between an account associated with the home device and a MAC address of a terminal device. For example, the correspondence, established by the server, between an account associated with the home device and a MAC address of a terminal device may be listed in Table 2.

Optionally, in this embodiment, when an account associated with the home device is registered, the one or more terminal devices may send information about the account and a MAC address of the terminal device to the server. Alternatively, after an account associated with the home device is logged in, the one or more terminal devices may send information about the account and a MAC address of the terminal device to the server. Alternatively, the one or more terminal devices may send an account associated with the home device and a MAC address of the terminal device to the server at another moment. This is not limited in this embodiment.

TABLE 2 Information about an account MAC address of a terminal device Account 1 MAC 1 Account 2 MAC 2 Account 3 MAC 3 Account 4 MAC 4

S902: The home device sends operation information to the server. Correspondingly, the server receives the operation information from the home device.

The operation information is used to indicate an operation performed by a user on the home device.

In this embodiment, when the user directly performs an operation on the home device, the home device may send the operation information to the server. For a specific manner thereof, refer to step S401. For a specific manner of the home device having a voice recognition capability, refer to step S702. Details are not described herein again. After receiving the operation information, the server may determine, by using the following steps S903 to S905a or S903 to S905b, an account of the user who currently controls the home device.

S903: The server obtains a MAC address of the one or more terminal devices.

The one or more terminal devices are terminal devices on which accounts associated with the home device are logged in, and the one or more terminal devices and the home device are located in a same network.

Optionally, in this embodiment, the server may obtain the MAC address of the one or more terminal devices in the following three manners.

Manner 1 includes the following steps.

a. The server receives, from the home device, a sorting result of the MAC address of the one or more devices that are in the same network as the home device. Correspondingly, the server receives the sorting result of the MAC address.

The sorting result of the MAC address is obtained based on a signal strength of the network corresponding to a MAC address of each of the one or more devices.

Optionally, in this embodiment, the home device may listen on a network air interface, obtain the MAC address of the device that is in the same network (for example, with a same network identifier) as the home device, sort the obtained MAC address based on the signal strength of the corresponding network, and send the sorting result of the MAC address to the server.

It should be noted that, in this embodiment, the one or more devices that are in the same network as the home device may include a device having a network connection function, for example, a terminal device (a mobile phone and a tablet computer of family members in a family at a current moment) and other home devices. The network may be a wireless network such as a home Wi-Fi network, or may be a network of another type. This is not limited in this embodiment.

For example, the home device is located in a network 1. MAC address information of the one or more devices that are in the same network 1 as the home device and a signal strength of the network 1 corresponding to each of the one or more devices may be listed in Table 3. It can be understood from Table 3 that there are four devices in the same network 1 as the home device. A result obtained after the home device sorts MAC addresses of the four devices based on the signal strength of the network 1 corresponding to a MAC address of each device is listed in Table 3.

TABLE 3 Network identifier Device MAC address information Network signal strength Network 1 Device 1 MAC 1 3 Network 1 Device 2 MAC 2 1 Network 1 Device 3 MAC 3 2 Network 1 Device 4 MAC 4 4

TABLE 4 Sorting result Device MAC address information Network signal strength 1 Device 4 MAC 4 4 2 Device 1 MAC 1 3 3 Device 3 MAC 3 2 4 Device 2 MAC 2 1

b. The server obtains the MAC address of the one or more terminal devices from the sorting result of the MAC address reported by the home device.

The one or more terminal devices are the terminal devices on which the accounts associated with the home device are logged in, and the one or more terminal devices include the target terminal device.

The server may obtain the MAC address of the terminal device on which the accounts associated with the home device are logged in and an account logged in on the terminal device, and then compare a MAC address of the terminal device on which the account is logged in with the sorting result of the MAC address reported by the home device. In this way, the MAC address of the one or more terminal devices can be determined. For example, the sorting result of the MAC address reported by the home device includes the content listed in Table 4. The MAC address of the one or more terminal devices obtained by the server may be listed in Table 5.

TABLE 5 Sorting result Device Account logged in on the device MAC address information Network signal strength 2 Device 1 Account 1 MAC 1 3 4 Device 2 Account 2 MAC 2 1

Manner 2 includes the following steps.

a. The server receives, from the home device, the MAC address of the one or more devices that are in the same network as the home device and a signal strength of the network corresponding to a MAC address of each of the one or more devices.

For related description of the MAC address of the one or more devices that are in the same network as the home device and the signal strength of the network corresponding to the MAC address of each of the one or more devices, refer to the foregoing Manner 1. Details are not described herein again.

Optionally, in this embodiment, the home device may listen on a network air interface, obtain the MAC address of the device that is in the same network (for example, with a same network identifier) as the home device and the signal strength of the network corresponding to each MAC address, and send the obtained MAC address and the signal strength of the network corresponding to each MAC address to the server.

b. The server sorts, based on the signal strength of the network corresponding to the MAC address of each device, the obtained MAC address and the signal strength of the network corresponding to the obtained MAC address. For example, the foregoing content obtained by the server is the content listed in Table 3. A result obtained after the server performs sorting may be listed in Table 4. Details are not described herein again.

c. After obtaining the sorting result, the server obtains, based on the sorting result, the MAC address of the one or more terminal devices and the signal strength of the network corresponding to the MAC address of each terminal device of the one or more terminal devices. For related description thereof, refer to step b in the foregoing Manner 1. Details are not described herein again.

Manner 3 includes the following steps.

a. The server sends a MAC address related information query message to one or more first terminal devices.

The one or more first terminal devices are the terminal devices on which the accounts associated with the home device are logged in, the one or more first terminal devices may be located in different networks, and the one or more first terminal devices include the target terminal device.

b. The server receives MAC address related information from the one or more first terminal devices.

The MAC address related information may include: a MAC address of the first terminal device, an identifier of a network corresponding to the MAC address of the first terminal device, and a signal strength of the network corresponding to the MAC address of the first terminal device.

c. The server obtains, from the MAC address related information of the one or more first terminal devices, the MAC address of the one or more terminal devices that are in the same network as the home device and a signal strength of a network corresponding to a MAC address of each terminal device of the one or more terminal devices.

Before step c is performed, the server may obtain an identifier of the network in which the home device is located.

For example, content of the MAC address related information of the one or more first terminal devices received by the server may be listed in Table 6. A terminal device corresponding to a MAC 1 and a terminal device corresponding to a MAC 2 are located in a same network 1, a terminal device corresponding to a MAC 3 is located in a network 2, and a terminal device corresponding to a MAC 4 is located in a network 3. If the identifier, obtained by the server, of the network in which the home device is located is 1, MAC addresses that are of terminal devices in the same network as the home device and that are obtained by the server are the MAC 1 and the MAC 2, and correspondingly signal strengths of the network 1 are 2 and 1.

TABLE 6 Network identifier MAC address of a terminal device Account logged in on the terminal device Network signal strength Network 1 MAC 1 Account 1 3 Network 1 MAC 2 Account 2 1 Network 2 MAC 3 Account 3 4 Network 3 MAC 4 Account 4 3

d. The server sorts the MAC address of the one or more terminal devices based on the signal strength of the network.

For example, the MAC address related information obtained by the server includes the content listed in Table 6. A result obtained after the server sorts the MAC address of the one or more terminal devices based on the signal strength of the network is listed in Table 7.

TABLE 7 Sorting result Network identifier MAC address of a terminal device Account logged in on the terminal device Network signal strength 1 Network 1 MAC 1 Account 1 3 2 Network 1 MAC 2 Account 2 1

S904: The server determines a MAC address corresponding to a highest signal strength of the network in the MAC address of the one or more terminal devices.

The server may determine, based on the sorting result obtained in any one of the foregoing three manners in step S903, the MAC address corresponding to the highest signal strength of the network in the MAC address of the one or more terminal devices. For example, the MAC address that is corresponding to the highest signal strength of the network and that is determined by the server may be the MAC 1.

S905a: The server determines, as the target account, an account logged in on a terminal device corresponding to the MAC address corresponding to the highest signal strength of the network.

Optionally, if the server does not perform step S901, the server may perform step S905a, to determine, as the target account, the account logged in on the terminal device corresponding to the MAC address corresponding to the highest signal strength of the network. For example, the target account determined by the server may be the account 1 logged in on the terminal device corresponding to the MAC 1.

S905b: The server determines, as the target account based on the correspondence between a MAC address and an account, an account corresponding to the MAC address corresponding to the highest signal strength of the network.

Optionally, if the server performs step S901, the server may perform step S905b, to determine, as the target account based on the correspondence between a MAC address and an account, the account corresponding to the MAC address corresponding to the highest signal strength of the network.

It should be noted that, when the server performs step S901, the server may determine the target account in the manner in step S905a. This is not limited in this embodiment.

S906: The server sends a notification message to the target terminal device. Correspondingly, the target terminal device receives the notification message from the server.

As described above, in this embodiment, that the terminal device on which the target account is logged in is the target terminal device is used as an example for description. The notification message includes status information used to indicate a status of the home device, and the status of the home device is related to the operation information. For example, the user currently controls the air conditioner shown in FIG. 8. The status information of the home device may be “a current specified temperature is 21 degrees”, and an interface displayed after the first terminal device receives the notification message may be shown in FIG. 6. Alternatively, for example, the user currently controls a rice cooker. The status information of the home device may be “rice cooking ends at 12:30”.

Optionally, in this embodiment, after receiving the notification message from the server, the target terminal device may determine the status of the home device based on the notification message, to perform a subsequent operation. For example, the notification message received by the target terminal device includes “rice cooking ends at 12:30”. The target terminal device may determine whether current time is later than 12:30. If the current time is later than 12:30 (for example, the current time is 12:31), the target terminal device may notify, in a vibration or ringing manner, the user that rice cooking has ended. Alternatively, the target terminal device may control, by using the target account logged in on the target terminal device, the rice cooker to be powered off or enter a heat preservation mode.

In the communications method provided in this embodiment, the home device sends the operation information to the server, where the operation information is used to indicate the operation performed by the user on the home device. After receiving the operation information from the home device, the server determines the MAC address corresponding to the highest signal strength of the network in the MAC address of the one or more terminal devices that are in the same network as the home device; determines, as the target account, the account logged in on the terminal device corresponding to the MAC address corresponding to the highest signal strength of the network, or determines, as the target account based on the correspondence between a MAC address and an account, the account corresponding to the MAC address corresponding to the strongest network signal; and sends the notification message to the target terminal device on which the target account is logged in, where the notification message includes the status information used to indicate the status of the home device. In this embodiment, when the user controls the home device, the server can determine the target account, and send the notification message including the status information of the home device to the terminal device on which the target account is logged in. This prevents unwanted information from being received by an account other than the target account, thereby enhancing user experience.

It can be understood that, in the foregoing embodiments, the methods and/or steps implemented by the first terminal device may alternatively be implemented by a component (for example, a chip or a circuit) that can be used for the first terminal device, the methods and/or steps implemented by the home device may alternatively be implemented by a component (for example, a chip or a circuit) that can be used for the home device, and the methods and/or steps implemented by the server may alternatively be implemented by a component (for example, a chip or a circuit) that can be used for the server.
