Referring to fig. 1, fig. 1 is a schematic diagram of a communication system according to an embodiment of the present application. As shown in fig. 1, in 1-1 of fig. 1, the communication system includes a terminal device 10 and a device cloud 11, and a specific communication link between the terminal device 10 and the device cloud 11. In the present application, the communication link may also be referred to as a communication channel. Alternatively, the communication link between the terminal device and the device cloud may be, for example, a message queue telemetry transport (message queue telemetry transport, MQTT) communication link, i.e., an MQTT long connection. The terminal device 10 may send status information to the device cloud 11 via the communication link. In the present application, the status information is used to indicate the status of the function provided by the terminal device, for example, the status information may be used to indicate whether the function provided by the terminal device is in an on state or an off state. The functions provided by the terminal device may for example comprise one of the following: and applying a connection function and a call sharing function. The application connection may be understood as that when a user uses an application in one terminal device, the user may connect the use state of the application in another terminal device that meets the connection condition, and continue to use the application. In the present application, an application may also be referred to as an application program (APP), which may be a computer program that performs one or more specific functions. It may have a visual display interface that can interact with the user; alternatively, the user may not be able to interact with the display interface without being visually displayed. By way of example, applications may be divided into third party applications and system applications, wherein the third party applications may be understood as applications installed by a user on a terminal device, such as one or more of applications with navigation functions, applications with instant messaging functions, etc.; a system application may be understood as an application preset by the operating system, such as an application with a dialing function, etc. Call sharing can be understood as: different users can realize real-time conversation, content sharing, message interaction and the like through the terminal equipment. Generally, when detecting that the state information in the terminal device 10 changes, the state information to be sent to the device cloud 11 exists in the terminal device 10, so that new state information may be sent to the device cloud 11, or when detecting that the position of the terminal device 10 changes, the state information to be sent to the device cloud 11 exists in the terminal device 10, so that current state information may be sent to the device cloud 11. Referring to fig. 2, fig. 2 is a schematic view of a scene provided by an embodiment of the present application. As shown in fig. 2, in 2-1 of fig. 2, when the user clicks a button 201A of an application continuation function on the screen of the terminal device 200A, the application continuation function provided by the terminal device is turned on. In addition, it can be seen that the button 202A of the call sharing function on the screen of the terminal device 200 is in an off state. That is, when it is detected that the state information in the terminal device 200 changes, the state information to be transmitted to the device cloud 203A exists in the terminal device 200A, and thus new state information may be transmitted to the device cloud 203A, which may be used to indicate that the application continuation function provided by the terminal device is in an on state and the call sharing function provided by the terminal device is in an off state. In fig. 2-2, when the terminal device 201B moves from the left side of the large screen device 200B to the right side of the large screen device 200B, state information to be transmitted to the device cloud 202B exists in the terminal device 201B, and the terminal device 201B may transmit the current state information to the device cloud 202B.

In 1-2 of fig. 1, the communication system includes a terminal device 20, a terminal device 21, a device cloud 22, and a push (push) cloud 23, where a communication link between the terminal device 21 and the device cloud 22 is disconnected, that is, the terminal device 21 and the device cloud 22 do not have a communication link, at this time, after the terminal device 20 sends status information to the device cloud 22, the device cloud 22 may send the status information to the terminal device 21 through the push cloud 23. Wherein, a communication link is provided between the device cloud 22 and the push cloud 23, and the communication link between the device cloud 22 and the push cloud 23 may be referred to as a push channel. Alternatively, the communication link between the device cloud 22 and the push cloud 23 may be a unidirectional communication link, that is, the device cloud 22 may send data to the push cloud 23, but the push cloud 23 cannot send data to the device cloud 22.

In the present application, the terminal device is an electronic device having data processing capability or data transmitting/receiving capability. The terminal device may be, for example, a mobile phone, a tablet (Pad), a Personal Computer (PC), a large screen device, a smart television, etc. The embodiment of the application does not limit the specific equipment form of the terminal equipment. The terminal device can be used as a master control device or a controlled device. The master device is usually an electronic device that can provide services including calls, videos, music and various other application software, and often serves as a device that is directly perceived and used by a user, and can control and modify the provision of a controlled device under the same account number associated with the master device. The master control device cannot be modified by other devices, so that the state information cannot be changed, and the state information cannot be reported to the device cloud through a communication link between the master control device and the device cloud. Further, when the communication link between the master control device and the device cloud is disconnected, the communication connection cannot be restored, and all messages need to be sent to the master control device through the communication link between the device cloud and the push cloud, but because the number of services carried by the push cloud is far greater than that of the device cloud, if the messages depend on the communication link between the device cloud and the push cloud completely, the timeliness of arrival of the messages is reduced greatly, so that the master control device can continue to use the MQTT long connection to meet the data transmission requirement. The controlled device generally refers to a terminal device that can provide a specific single function, service. The user can select to directly operate the controlled device to modify the state information, change the working state of the controlled device, and also can control the controlled device to modify the state information through the main control device. A common controlled device may be an internet of things (internet of things, ioT) device, including a router, an air conditioner, a washing machine, a desk lamp, and the like.

In the present application, a device cloud or push cloud may be used to receive status information. The device cloud and the push cloud may be referred to as a device cloud server and a push cloud server, respectively. The server mentioned in the embodiments of the present application may be one server, or may be a server cluster formed by a plurality of servers. Specifically, the server may include a server that centrally stores the state information, or may include a server cluster that is distributed and configured to store the state information in a distributed manner. For example, the distributed server may be a server cluster formed by a plurality of servers, where the cluster may include a cloud computing server, a content delivery network (Content Delivery Network, CDN) server, a network time protocol (Network Time Protocol, NTP), a domain name resolution system (Domain Name System, DNS) server, and the like, where the servers may coordinate with each other to perform functions of computing, data storage, communication, and the like, and for convenience of description, the individual servers, the distributed servers, and the server cluster are collectively referred to as a server in the embodiment of the present application.

Referring to fig. 3, fig. 3 is a flow chart of a communication method according to an embodiment of the present application. The server of the embodiment shown in fig. 3 is a device cloud server. The method includes, but is not limited to, the steps of:

301. The terminal device determines whether state information to be sent to the device cloud server exists in the terminal device in a first time, and a communication link is arranged between the terminal device and the device cloud server.

In the embodiment shown in fig. 3, the terminal device is not normally powered, i.e. the terminal device is a device that is not continuously powered by a power source, i.e. the terminal device is a device that requires various forms of power supply, such as batteries, solar energy, etc.

Wherein the terminal device may determine the first time by any one of the following means. What way is specifically adopted depends on the implementation of the terminal device, the definition of a pre-defined agreement or standard.

The method comprises the steps that firstly, terminal equipment determines power consumption of the terminal equipment; the terminal device determines a first time according to the power consumption of the terminal device. The determining, by the terminal device, the power consumption of the terminal device may include, for example: the terminal equipment determines the power consumption of the terminal equipment according to the time that each process in the terminal equipment occupies the central processing unit (central processing unit, CPU). Alternatively, the respective processes in the terminal device may be, for example, one or more processes of the first application running at the terminal device. The number of first applications may be one or more, and the first applications may be applications determined by the terminal device according to one or more of a frequency used by a user, a type of application, and the like, for example. One process of the first application may be, for example, one process of an application having a navigation function, one process of an application having an instant messaging function, or the like. The types of applications may include, for example, one or more of instant messaging, position location, entertainment, and the like. This means that the first time can be determined in dependence of the power consumption of the terminal device, enabling a dynamic adjustment of the first time.

The method comprises the steps that a terminal device obtains a plurality of historical time intervals, wherein each historical time interval in the plurality of historical time intervals is a time interval in which the terminal device sends historical state information to a device cloud server through a communication link twice; the terminal device determines a first time according to the plurality of historical time intervals. Optionally, the terminal device obtains a plurality of historical time intervals, including: the terminal device receives a plurality of historical time intervals transmitted by the device cloud server through a communication link. Optionally, the determining, by the terminal device, the first time according to the plurality of historical time intervals includes: the terminal device determines the first time according to an average value, a maximum value, a minimum value or a median of the plurality of historical time intervals. This means that the first time can be determined from a plurality of historical time intervals, enabling dynamic adjustment of the first time.

The third mode and the first time can be preconfigured in the terminal equipment.

The first time may be, for example, 5 minutes.

Optionally, the method may further include: the method comprises the steps that a terminal device starts a first timer at a first moment, wherein the first moment is the moment when the terminal device sends first state information to a device cloud server through a communication link, and the first moment is the running time of the first timer; the terminal device determining whether state information to be sent to the device cloud server exists in the terminal device in a first time, including: and determining whether state information to be sent to the device cloud server exists in the terminal device before the first timer is overtime. This defines the moment when the terminal device starts the first timer, and thus it can be determined whether there is status information to be sent to the device cloud server in the terminal device before the first timer expires.

Optionally, the method may further include: and when the first condition is met, the terminal equipment starts a communication connection disconnection mode. Wherein the first condition comprises at least one of: the terminal equipment detects a mode setting instruction, wherein the mode setting instruction is used for starting a communication connection disconnection mode; the terminal device detects that the power consumption of the terminal device is lower than the preset power consumption. The terminal device starts the communication connection disconnection mode, which can be understood as the terminal device performing steps 301-302. This indicates that the terminal device can open the communication connection disconnection mode when a certain condition is satisfied, and flexibility of the terminal device in opening the communication connection disconnection mode is improved.

Optionally, the method may further include: the method comprises the steps that terminal equipment sends a first registration request message to an equipment cloud server, wherein the first registration request message comprises equipment identification and account numbers of the terminal equipment, and the equipment identification and account numbers of the terminal equipment are used for establishing a communication link with the equipment cloud server; the terminal equipment receives a response message of a first registration request message sent by the equipment cloud server through a communication link between the terminal equipment and the equipment cloud server, wherein the response message of the first registration request message is used for indicating that the communication link between the terminal equipment and the equipment cloud server is successfully established. The device identifier of the terminal device may be, for example, a token (token) of a second application running on the terminal device, where the second application is an application having one or more of an application connection function, a call sharing function, and the like. The account number can be associated with other devices except the terminal device, that is, one account number can be associated with a plurality of terminal devices, and different terminal devices can be registered to the device cloud server by using the same account number, so that the master control device can discover and acquire other controlled devices under the account number, and further, the master control device can control and modify the state information of the controlled devices.

The first registration request message may further include a type identifier to which the terminal device belongs, and the type to which the terminal device belongs may include, for example, a super terminal device, a master device, or a controlled device. It should be understood that the type identifier to which the terminal device belongs may be, for example, a device type code, and the type identifier to which the terminal device belongs may be preconfigured in the terminal device. The response message of the first registration request message may further include a cloud identifier allocated by the device cloud server to the terminal device, that is, a cloud identifier of the terminal device. It should be understood that in the present application, the cloud identification of the terminal device may be used to uniquely identify the terminal device.

In a possible implementation manner, the response message of the first registration request message may further include a type identifier to which all terminal devices under the account belong, and the method further includes: if the controlled equipment identifier exists in the type identifiers of all the terminal equipment under the account, and the type identifier of the terminal equipment is the super terminal equipment identifier, the terminal equipment sends a second registration request message to the equipment cloud server through a communication link between the terminal equipment and the equipment cloud server, the second registration request message is used for registering the terminal equipment as the main control equipment, the terminal equipment receives a response message of the second registration request message sent by the equipment cloud server through the communication link, and the response message of the second registration request message is used for indicating that the terminal equipment is successfully registered as the main control equipment. The second registration request message may further include a cloud identifier of the terminal device. When the controlled equipment appears in the networking, namely, the controlled equipment appears in all terminal equipment under the same account, the terminal equipment can register an equipment role again according to the current requirement, and further, different service requirements can be better met. Meanwhile, it can be seen that the terminal device is a super terminal device and a master control device at the moment.

It should be noted that, when the controlled device identifier exists in the type identifiers to which all the terminal devices belong under the account, other super terminal devices except the terminal device under the account may also be registered as the master device, and the specific registration process is not repeated herein.

Optionally, the method may further include: the terminal equipment receives type identifiers of all terminal equipment under the updated account sent by the equipment cloud server through the communication link; if the controlled equipment identifier does not exist in the type identifiers of all the terminal equipment under the updated account, the terminal equipment sends an equipment role deleting message to the equipment cloud server through the communication link, the equipment role deleting message is used for deleting the main control equipment role of the terminal equipment, the terminal equipment receives a response message of the equipment role deleting message sent by the equipment cloud server through the communication link, and the response message of the equipment role deleting message is used for indicating that the main control equipment role of the terminal equipment is successfully deleted. The delete device role message may also include a cloud identification of the terminal device. The method indicates that when the last controlled device in the networking is off line, namely, when the controlled device does not exist in all the terminal devices under the same account, the terminal device can cancel the role of the main control device according to the current requirement, only the role of the super terminal device is reserved, and further different service requirements can be better met.

In another possible implementation manner, if the super terminal device identifier exists in the type identifiers to which all the terminal devices belong under the account, and the type identifier to which the terminal device belongs is the super terminal device identifier, the terminal device is still the super terminal device and is not registered as the master control device. Of course, other super terminal devices except the terminal device under the account number are not registered as the master control device. This may meet the interaction requirements between different superterminal devices.

Optionally, the method may further comprise step 302.

302. If the state information to be sent to the equipment cloud server does not exist in the terminal equipment in the first time, the terminal equipment breaks the communication link.

Optionally, the method may further include: when the existence of second state information to be sent to the equipment cloud server in the terminal equipment is detected, reestablishing a communication link between the terminal equipment and the equipment cloud server; and sending the second state information to the device cloud server through the communication link. This means that when it is detected that there is second status information within the terminal device to be sent to the device cloud server, the communication link may be re-established so that the status information of the terminal device may still be sent to the device cloud server.

It can be seen that, because the state information to be sent to the equipment cloud server does not exist in the terminal equipment in the first time, the terminal equipment breaks the communication link, so that the problem of high energy consumption of the terminal equipment caused by the maintenance of the communication link by the terminal equipment can be solved.

Referring to fig. 4, fig. 4 is a flow chart of another communication method according to an embodiment of the present application. The first server in the embodiment shown in fig. 4 is a device cloud server, and the second server is a push cloud server. The method includes, but is not limited to, the steps of:

401. the second terminal equipment sends a first message to the equipment cloud server through a first communication link, wherein the first message comprises first state information of the second terminal equipment, the first communication link is a communication link between the equipment cloud server and the second terminal equipment, and no communication link exists between the equipment cloud server and the first terminal equipment.

Correspondingly, the device cloud server receives a first message sent by the second terminal device through the first communication link.

The process of establishing the first communication link between the device cloud server and the second terminal device may refer to the process of establishing the communication link in fig. 3, which is not described herein.

It should be noted that, there is no communication link between the device cloud server and the first terminal device, for example, it may be understood that: the communication link between the device cloud server and the first terminal device has been broken.

Optionally, the first message further includes a cloud identifier of the second terminal device, and sending, by pushing the cloud server, the second message to the first terminal device includes: according to the cloud identification of the second terminal equipment, acquiring the cloud identification of at least one terminal equipment under the same account associated with the second terminal equipment, wherein the identification of the at least one terminal equipment comprises the cloud identification of the first terminal equipment; determining the equipment identifier of the first terminal equipment according to the cloud identifier of the first terminal equipment and the association relationship between the cloud identifier of the first terminal equipment and the equipment identifier of the first terminal equipment; and sending a second message to the first terminal equipment through the pushing cloud server according to the equipment identifier of the first terminal equipment. It can be seen that the device cloud server can obtain, according to the cloud identifier of the second terminal device, the cloud identifier of at least one terminal device associated with the same account number as the second terminal device, where the identifier of the at least one terminal device includes the cloud identifier of the first terminal device, so that the device cloud server can obtain, according to the cloud identifier of the first terminal device, the device identifier of the first terminal device, and further can obtain, according to the device identifier of the first terminal device, to which device the second message needs to be pushed.

In the application, the cloud identifier of the terminal equipment is the cloud identifier distributed by the equipment cloud server for the terminal equipment, and the cloud identifier of the terminal equipment can be used for uniquely identifying the terminal equipment.

The device identifier of the terminal device may be, for example, a token (token) of a first application running on the terminal device, where the first application is an application having one or more of an application connection function, a call sharing function, and the like.

The association relationship between the cloud identifier of the first terminal device and the device identifier of the first terminal device can be understood as: the cloud identification of the first terminal device and the device identification of the first terminal device. The cloud identification of the first terminal device and the device identification of the first terminal device may be stored in association by the device cloud server in the device cloud server.

402. And the equipment cloud server sends a second message to the first terminal equipment through the pushing cloud server, wherein the second message comprises the first state information.

Correspondingly, the first terminal device receives a second message sent by the device cloud server through the push cloud server.

Optionally, the receiving, by the first terminal device through the push cloud server, the second message sent by the device cloud server may include, for example: and when the first terminal equipment is in the awakening state or the first terminal equipment enters the awakening state from the sleep state, the first terminal equipment receives a second message sent by the equipment cloud server through the push cloud server. This indicates that the first terminal device is in the awake state or that the first terminal device may acquire the second message when it enters the awake state from the sleep state.

Optionally, the second message further comprises a device identification of the first terminal device.

Optionally, the second message further includes an identifier of the first application, where the identifier of the first application is determined by the device cloud server according to the cloud identifier of the second terminal device and an association relationship between the plurality of cloud identifiers and the identifier of the first application. The association relationship between the plurality of cloud identifications and the identification of the first application can be understood as follows: correspondence between the plurality of cloud identifications and the identification of the first application. Illustratively, cloud identification 1 corresponds to the identification of the first application, cloud identification 2 corresponds to the identification of the first application, and cloud identification 3 corresponds to the identification of the first application.

403. The first terminal device updates the state information of the second terminal device according to the first state information.

Optionally, the method further comprises: the first terminal equipment performs validity check on the second message according to the equipment identifier of the first terminal equipment; the first terminal device updates the state information of the second terminal device according to the first state information, and the method comprises the following steps: and when the validity check is passed, the first terminal equipment updates the state information of the second terminal equipment according to the first state information. It can be seen that by performing validity check on the second message according to the device identifier of the first terminal device, when the validity check passes, the state information of the second terminal device is updated according to the first state information, which can effectively check the forged data for attacking the first terminal device, thereby improving the security of the first terminal device.

The validity check of the second message by the first terminal device according to the device identifier of the first terminal device can be, for example, understood as: and the push service process in the first terminal equipment performs validity check on the second message according to the equipment identifier of the first terminal equipment. The push service process in the first terminal device compares the device identifier of the first terminal device with the device identifier stored in the first terminal device, so as to perform validity check on the second message. And when the validity check is not passed, the push service process in the first terminal equipment does not process the second message.

The first terminal device updates the state information of the second terminal device according to the first state information, for example, it can be understood that: and the push service process in the first terminal equipment sends the first state information to the process of the first application running on the first terminal equipment according to the identification of the first application, and the process of the first application running on the first terminal equipment updates the state information of the second terminal equipment into the first state information.

It can be seen that, under the condition that the device cloud server and the first terminal device do not have a communication link, the device cloud server can send the second message to the first terminal device by pushing the cloud server, so that the first terminal device can still receive the data of the device cloud server, and the problem of data loss caused by the fact that the device cloud server and the first terminal device do not have a communication link is solved.
