[0040] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0041] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. A person skilled in the art will appreciate that, with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0042] Please refer to Figure 1 , which shows a schematic diagram of a network architecture of the Internet of Things provided by an exemplary embodiment of the present application. The network architecture of the Internet of Things may include: a client device 110, a first cloud platform 120, and a second cloud platform 130;

[0043] The first cloud platform 120 and the second cloud platform 130 are cloud service platforms deployed on the network side. For example, the first cloud platform 120 and the second cloud platform 130 can be cloud service platforms implemented based on a single server or multiple servers.

[0044] The first cloud platform 120 may be a cloud platform from a different manufacturer than the client device, and the second cloud platform 130 may be a cloud platform from the same manufacturer as the client device. The second cloud platform 130 includes information corresponding to the client device.

[0045] The client device 110 may be a computer device with built-in management software, such as a smart phone, a tablet computer, a smart watch, a personal computer, such as a desktop computer, a portable computer, a personal workstation, etc.

[0046] The first cloud platform 120 is connected to the client device 110 and the second cloud platform 130 via a wired or wireless network.

[0047] Optionally, the wired or wireless network uses standard communication technologies and / or protocols. For example, the wired or wireless network may be a communication network based on an IoT protocol.

[0048] In an embodiment of the present application, the first cloud platform 120, the second cloud platform 130, and the client device 110 may be IoT devices that meet industry standards, for example, IoT devices that meet Open Connectivity Foundation (OCF) standards.

[0049] OCF is an emerging IoT application layer technology standards organization. OCF has developed a RESTful (a design style and development method for network applications) service framework to achieve interoperability between IoT devices. In the OCF service framework, IoT devices, as well as information such as the device's functional services and device status, are described through a device resource model. The IoT terminal device that provides resources is the OCF server (i.e., the aforementioned server device), and the control terminal that accesses resources is the OCF client (i.e., the aforementioned client device).

[0050] In an embodiment of the present application, the network architecture of the above-mentioned Internet of Things can be a network structure based on cloud-to-cloud interconnection, or it can be a network architecture based on cross-platform technology.

[0051] Please refer to Figure 2 , which shows a schematic diagram of a cloud-to-cloud interconnected structure. Figure 2As shown, the cloud-to-cloud (C2C) technology is implemented by an origin cloud client 210 , an origin cloud 220 , and a target cloud 230 .

[0052] The originating cloud terminal 210 may be a user terminal, and the originating cloud 220 may be a cloud server that establishes a communication connection with the originating cloud terminal 210. The originating cloud terminal 210 connects to each originating cloud server 221 of the originating cloud terminal 210 via a D2C (Device-to-Cloud) method in accordance with the OCF standard. Similarly, the target cloud 220 also connects to each target cloud server 231 of the target cloud 220 via a D2C method in accordance with the OCF standard.

[0053] This cloud-to-cloud technology, that is, through the cloud application program interface (OCF CloudAPI for Cloud Services) established for cloud servers in the OCF specification, establishes a communication channel between the two cloud platforms and connects the account systems of the two cloud platforms, so that a communication connection is established between the starting cloud 220 and the target cloud 230. The starting cloud terminal 210 corresponding to the starting cloud 220 can control the device corresponding to the target cloud 230 that has not established a communication connection with the starting cloud terminal through APP (Application) and other means.

[0054] Please refer to Figure 3 , which shows a schematic diagram of the structure of a cross-platform technology. Figure 3 As shown, the third-party server 300 is connected to the A smart home cloud service platform 310, the B smart home cloud service platform 320 and the C furniture cloud hub 330 through third-party interfaces.

[0055] In smart home cloud service platform A 310, home cloud A, control terminals, and local hubs establish communication connections with each other through non-standard interfaces. Specifically, home cloud A and the local hub communicate with each other through networking terminals. Similarly, in smart home cloud service platform B 320, home cloud B, control terminals, and local hubs establish communication connections with each other. Specifically, home cloud B and the local hub communicate with each other through networking terminals.

[0056] Through this cross-platform technology, the device produced by manufacturer A can directly access the platform of manufacturer B through the standardized cloud-to-cloud authentication interface after access authentication; thus, the APP of manufacturer B can also control device A through the B platform. Figure 3As shown, application terminals can access the network through a WiFi (Wireless Fidelity) device from manufacturer A or a WiFi device from manufacturer C. Alternatively, sub-devices from manufacturer X and manufacturer Y can be heterogeneously relayed and accessed through a narrowband gateway from manufacturer B. Smart home cloud service platform A 310, smart home cloud service platform B 320, and furniture cloud hub C 330 can perform access authentication through a third-party server 300, allowing data access between them. Therefore, application terminals accessing the network through any of the above methods can access cloud platforms from different manufacturers through standardized device interfaces. Apps on different platforms can also control devices from different manufacturers connected to the platform through the platform.

[0057] Please refer to Figure 4 , which shows a flow chart of a device upgrade control method provided by an exemplary embodiment of the present application, which can be executed by a first cloud platform, wherein the first cloud platform can be Figure 1 The first cloud platform 120 is shown. The method may include the following steps:

[0058] Step 401: Receive a notification message sent by a first device, where the notification message includes the latest version information of the client device; the first device includes at least one of the client device and a second cloud platform.

[0059] In one possible implementation, the first cloud platform and the client device are platforms and devices from different manufacturers. That is, the manufacturer of the first cloud platform and the client are different manufacturers. That is, the first cloud platform may not contain information corresponding to the client device, such as upgrade information or version information corresponding to the client.

[0060] Step 402: Obtain the current version information of the client device.

[0061] The version information is used to indicate the current version of the client device.

[0062] Step 403: When the version corresponding to the latest version information is higher than the version corresponding to the current version information, an upgrade message is sent to the client device. The upgrade message is used to trigger the client device to perform a version upgrade.

[0063] In one possible implementation, when the first device is a client device; when the client device accesses the first cloud platform, the device information of the client device is obtained, and the device information includes the device model of the client device; when the notification message corresponding to the device model is not subscribed to the client device, a second subscription upgrade information request is sent to the client device, and the second subscription upgrade information request includes the device model and the identifier of the first cloud platform; and the second subscription upgrade information acknowledgment response message sent by the client device is received.

[0064] In another possible implementation, when the first device is the second cloud platform, when the client device accesses the first cloud platform, device information of the client device is obtained, where the device information includes a device model of the client device;

[0065] When the notification message corresponding to the device model is not subscribed to the second cloud platform, sending a first subscription upgrade information request to the second cloud platform, the first subscription upgrade information request including the device model and an identifier of the first cloud platform;

[0066] Receive a first subscription upgrade information acknowledgement response message sent by the second cloud platform.

[0067] In one possible implementation, based on the address of the upgrade file, a first file acquisition request is sent to the second cloud platform; the upgrade file sent by the second cloud platform is received; and when a second file acquisition request sent by the client device is received, the upgrade file is sent to the client device.

[0068] In one possible implementation, the notification message also includes the address of the upgrade file of the client device; when a second file acquisition request sent by the client device is received, a first file acquisition request is sent to the second cloud platform based on the address of the upgrade file; the upgrade file sent by the second cloud platform is received; and the upgrade file is sent to the client device.

[0069] In a possible implementation, the first file acquisition request including the access credential is sent to the second cloud platform according to the address of the upgrade file.

[0070] In one possible implementation, the notification message includes the address of the upgrade file of the client device; when the third file acquisition request sent by the client device is received, an upgrade file acquisition response message is sent to the client device, and the upgrade file acquisition response message includes the address of the upgrade file.

[0071] In a possible implementation, the first subscription upgrade information response message and the upgrade file acquisition response message further include access credentials.

[0072] In a possible implementation, when the third file acquisition request sent by the client device is received, an address acquisition request is sent to the second cloud platform; the address acquisition request includes the device model;

[0073] Receive an address acquisition response sent by the second cloud platform, where the address acquisition response includes an address of an upgrade file for the client device;

[0074] An upgrade file acquisition response message is sent to the client device, where the upgrade file acquisition response message includes the address of the upgrade file.

[0075] In a possible implementation, the address acquisition response and the upgrade file acquisition reply message also include access credentials.

[0076] In summary, the solution shown in the embodiment of the present application is to receive the latest version message of the client device sent by the second cloud platform through the first cloud platform connected to the client device, and compare the latest version information of the client device with the current version information to determine whether the client device needs to be upgraded. When the client device needs to be upgraded, an upgrade message is sent to the client device, thereby upgrading the client device. In other words, in the above solution, the client device can directly instruct the upgrade process of the client device through the information exchange between the first cloud platform and the second cloud platform, thereby improving the upgrade control efficiency of the client device.

[0077] Please refer to Figure 5 , which shows a flow chart of a device upgrade control method provided by an exemplary embodiment of the present application, the method can be executed by a client device, wherein the client device can be Figure 1 The client device 110 is shown. The method may include the following steps:

[0078] Step 501: Receive an upgrade message sent by a first cloud platform, where the first cloud platform is the cloud platform to which the client device is connected.

[0079] The upgrade message is sent when the first cloud platform receives a notification message sent by the first device, and the version corresponding to the latest version information of the client device contained in the notification message is higher than the version corresponding to the current version information of the client device.

[0080] In a possible implementation, the second cloud platform and the client device are cloud platforms and client devices corresponding to the same manufacturer, that is, the manufacturer of the second cloud platform and the manufacturer of the client device are the same manufacturer.

[0081] The second cloud platform may include the latest version information corresponding to the client device. When the second cloud platform receives the notification message sent by the first cloud platform, it compares the current version information of the client device contained in the notification message with the latest version information corresponding to the client device included in the second cloud platform, and compares the latest version information with the current version information of the client. If the latest version information is higher than the current version information of the client, the notification message is sent; if the latest version information is not higher than the current version information of the client, the notification message is not sent, or a notification message is sent indicating that the client is not updated.

[0082] Step 502: Perform version upgrade according to the upgrade message.

[0083] In a possible implementation, a second file acquisition request is sent to the first cloud platform; an upgrade file of the client device sent by the first cloud platform is received; and a version upgrade is performed according to the upgrade file.

[0084] In one possible implementation, a third file acquisition request is sent to the first cloud platform; an upgrade file acquisition response message sent by the first cloud platform is received, and the upgrade file acquisition response message includes the address of the upgrade file of the client device; based on the address of the upgrade file, a fourth file acquisition request is sent to the second cloud platform; the upgrade file sent by the second cloud platform is received; and a version upgrade is performed based on the upgrade file.

[0085] In a possible implementation, a fourth file acquisition request including the access credential is sent to the second cloud platform according to the address of the upgrade file.

[0086] In one possible implementation, the first device is a client device; when the client device accesses the first cloud platform, the device information of the client device is sent to the first cloud platform, and the device information includes the device model of the client device; a second subscription upgrade information request sent by the first cloud platform is received; the second subscription upgrade information request is sent when the first cloud platform has not subscribed to the notification message corresponding to the device model to the client device; the second subscription upgrade information request includes the device model and the identifier of the first cloud platform; a second subscription upgrade information acknowledgment response message is sent to the first cloud platform; and the notification message is sent to the first cloud platform.

[0087] In one possible implementation, a notification query request is sent to the second cloud platform, where the notification query request is used to obtain the latest version information of the client device; the notification message sent by the second cloud platform is received; and the notification message is sent to the first cloud platform.

[0088] In summary, the solution shown in the embodiment of the present application is to receive the latest version message of the client device sent by the second cloud platform through the first cloud platform connected to the client device, and compare the latest version information of the client device with the current version information to determine whether the client device needs to be upgraded. When the client device needs to be upgraded, an upgrade message is sent to the client device, thereby upgrading the client device. In other words, in the above solution, the client device can directly instruct the upgrade process of the client device through the information exchange between the first cloud platform and the second cloud platform, thereby improving the upgrade control efficiency of the client device.

[0089] Please refer to Figure 6 , which shows a flow chart of a device upgrade control method provided by an exemplary embodiment of the present application, which can be executed by a second cloud platform, wherein the second cloud platform can be Figure 1 The second cloud platform 130 is shown. The method may include the following steps:

[0090] Step 601: When there is an upgrade file of the latest version of the client device, a notification message containing the latest version information is generated.

[0091] The latest version upgrade file is used to upgrade the client device from the current version state to the latest version state.

[0092] Step 602, sending the notification message to the second device so that the first cloud platform can obtain the current version information of the client device after receiving the notification message; when the version corresponding to the latest version information is higher than the version corresponding to the current version information, sending an upgrade message to the client device, and the upgrade message is used to trigger the client device to upgrade the version; the second device includes the client device or the second cloud platform.

[0093] The second device includes at least one of the client device and the first cloud platform.

[0094] In one possible implementation, a first subscription upgrade information request sent by the first cloud platform is received, where the first subscription upgrade information request includes the device model and an identifier of the first cloud platform; and a first subscription upgrade information acknowledgment response message is sent to the first cloud platform.

[0095] In one possible implementation, a first file acquisition request sent by the first cloud platform according to the address of the upgrade file is received; the upgrade file is sent to the first cloud platform; or a fourth file acquisition request sent by the client device according to the address of the upgrade file is received; and the upgrade file is sent to the client device.

[0096] In one possible implementation, receiving the first file acquisition request including the access credential sent by the first cloud platform according to the address of the upgrade file; receiving the fourth file acquisition request sent by the client device according to the address of the upgrade file includes: receiving the fourth file acquisition request including the access credential sent by the client device according to the address of the upgrade file.

[0097] In one possible implementation, the notification message also includes the address of the upgrade text; an address acquisition request sent by the first cloud platform based on the address of the upgrade file is received; the address acquisition request includes the device model; an address acquisition response is sent to the first cloud platform based on the device model, and the address acquisition response includes the address of the upgrade file of the client device; a fourth file acquisition request sent by the client device based on the address of the upgrade file is received; and the upgrade file is sent to the client device.

[0098] In a possible implementation, the address acquisition response and the fourth file acquisition request include access credentials.

[0099] In a possible implementation, when the second device is the client device, a notification query request sent by the client device is received, where the notification query request is used to obtain the latest version information of the client device; and the notification message is sent to the client device.

[0100] In summary, the solution shown in the embodiment of the present application is to receive the latest version message of the client device sent by the second cloud platform through the first cloud platform connected to the client device, and compare the latest version information of the client device with the current version information to determine whether the client device needs to be upgraded. When the client device needs to be upgraded, an upgrade message is sent to the client device, thereby upgrading the client device. In other words, in the above solution, the client device can directly instruct the upgrade process of the client device through the information exchange between the first cloud platform and the second cloud platform, thereby improving the upgrade control efficiency of the client device.

[0101] Please refer to Figure 7 , which shows a flow chart of a device upgrade control method provided by an exemplary embodiment of the present application. The method can be jointly performed by a client device, a first cloud platform, and a second cloud platform. When the first device is the second cloud platform, the method can include the following steps:

[0102] S701, the client device accesses the first cloud platform.

[0103] In a possible implementation, the client device and the first cloud platform are products of different manufacturers, and the client device and the first cloud platform are connected via a cross-platform technology.

[0104] That is, the client device and the first cloud platform may not be products developed based on the same development platform, or the first cloud platform may not support direct connection with the client device and needs to be connected through cross-platform technology. For example, developers can write connection programs in a cross-platform language to achieve cross-platform connection between the client device and the cloud platform.

[0105] In a possible implementation, the client device is connected to the first cloud platform through product access authentication.

[0106] The client device may perform product access authentication by sending information such as the device identification, client version, and manufacturer ID corresponding to the client device.

[0107] In a possible implementation, when the client device accesses the first cloud platform, the first cloud platform obtains device information of the client device, where the device information includes a device model of the client device.

[0108] In one possible implementation, after the client device is connected to the first cloud platform through product access authentication, the client device transmits the device information corresponding to the client device to the first cloud platform, wherein the device information may include the client device model, the manufacturer identification corresponding to the client, the manufacturer upgrade server address, the current version information corresponding to the client, etc.

[0109] In a possible implementation, when the client device accesses the first cloud platform, the first cloud platform obtains device information of the client device and determines a platform corresponding to the device information (ie, the second cloud platform) based on the device information.

[0110] The first cloud platform may also be connected to the second cloud platform via cross-platform technology.

[0111] In one possible implementation, the first cloud platform detects whether the notification message corresponding to the client device is subscribed to the second cloud platform. When the first cloud platform detects that the first cloud platform has subscribed to the notification message corresponding to the client device from the second cloud platform, the first cloud platform can receive the notification message issued by the second cloud platform according to the latest version corresponding to the client device; when the first cloud platform does not detect that the notification message corresponding to the client device is subscribed to the second cloud platform, it indicates that the first cloud platform needs to subscribe to the notification message from the second cloud platform, so that when the second cloud platform contains the latest version of the client device, the first cloud platform can receive the notification message.

[0112] In a possible implementation, the first cloud platform is based on manufacturer information corresponding to the client device.

[0113] In a possible implementation, the first cloud platform may determine whether it has subscribed to the notification message corresponding to the client device by detecting whether the first cloud platform includes the notification message corresponding to the client device sent by the second cloud platform.

[0114] S702: The first cloud platform sends a first subscription upgrade information request to the second cloud platform.

[0115] In one possible implementation, when the first cloud platform has not subscribed to the notification message corresponding to the device model from the second cloud platform, the first cloud platform sends a first subscription upgrade information request to the second cloud platform, and the first subscription upgrade information request includes the device model and the identifier of the first cloud platform.

[0116] S703: The first cloud platform receives the first subscription upgrade information response message sent by the second cloud platform.

[0117] In one possible implementation, the second cloud platform receives a first subscription upgrade information request sent by the first cloud platform, where the first subscription upgrade information request includes the device model and the identifier of the first cloud platform; the second cloud platform sends a first subscription upgrade information acknowledgment response message to the first cloud platform.

[0118] The first subscription upgrade information response message is used to indicate that the second cloud platform has successfully received the first subscription upgrade information request sent by the first cloud platform, that is, the second cloud platform has successfully subscribed to the upgrade information corresponding to the client device from the first cloud platform.

[0119] S704: When the second cloud platform has the latest version of the upgrade file for the client device, a notification message containing the latest version information is generated.

[0120] In a possible implementation, the notification message further includes the address of the upgrade text.

[0121] In another possible implementation, the notification message also includes a device model corresponding to the client device.

[0122] S705: The second cloud platform sends the notification message to the first cloud platform, where the first cloud platform is the cloud platform to which the client device accesses.

[0123] Correspondingly, the first cloud platform receives a notification message sent by the second cloud platform, where the notification message includes the latest version information of the client device.

[0124] In one possible implementation, the notification message is used to trigger the first cloud platform to send an upgrade message to the client device when the version corresponding to the latest version information is higher than the version corresponding to the current version information of the client device. The upgrade message is used to instruct the client device to upgrade its version.

[0125] In one possible implementation, the notification message includes the address of the upgrade file of the client device; when the first cloud platform receives the third file acquisition request sent by the client device, it sends a first upgrade file acquisition response message to the client device, and the first upgrade file acquisition response message includes the address of the upgrade file.

[0126] In a possible implementation, the first subscription upgrade information response message and the upgrade file acquisition response message further include access credentials.

In other words, in the above solution, the client device can directly instruct the first cloud platform on the upgrade process of the client device through information exchange between the first cloud platform and the second cloud platform, thereby improving the upgrade control efficiency of the client device.

[0221] Please refer to Figure 9 This is a schematic diagram of the device upgrade control process provided by an exemplary embodiment of the present application. Figure 7 As shown, taking the first cloud platform and the second cloud platform as servers as an example, the above Figure 5 In the solution shown, the data transmission process between the terminal and the first cloud platform and the second cloud platform is as follows:

[0222] S901: Product access authentication and access. Device A (client device) passes the product access authentication of CloudB (first cloud platform) and connects to CloudB.

[0223] The device A and CloudB may be products from different manufacturers, that is, the network platforms on which the device A and CloudB are located are different. Therefore, a cross-platform technology is required to connect the device A and CloudB.

[0224] S902, CloudB obtains information such as the model, manufacturer, manufacturer upgrade server address, and current version of device A.

[0225] Among them, the model, manufacturer, manufacturer upgrade server address, current version and other information of device A can be obtained by CloudB by sending an acquisition request to device A, or can be sent by device A to CloudB during the product access authentication process with CloudB.

[0226] S903, CloudB confirms whether the device of this model has subscribed to the upgrade information on the product upgrade server.

[0227] The device model is the device model corresponding to Device A, and the product upgrade server is CloudA (the second cloud platform) corresponding to Device A. If CloudB has subscribed to the upgrade information corresponding to the device model from CloudA, that is, CloudB already has the upgrade information corresponding to the device model issued by CloudA, Device A can directly send a request to CloudB for an update. If CloudB has not subscribed to the upgrade information corresponding to the device model from CloudA, CloudB cannot instruct Device A to complete the device upgrade, and therefore CloudB needs to complete further information exchange with CloudA.

The first subscription upgrade information response message may be a response message (200OK) sent upon receiving a message in the IMS network communication, indicating that the server corresponding to CloudA has received the first subscription upgrade information request sent by CloudB.

[0232] S906, CloudA sends a subscription notification message (notification message) to CloudB.

[0233] The subscription notification message is sent by CloudA after CloudA receives the subscription upgrade request sent by CloudB and agrees to the subscription upgrade request sent by CloudB. The subscription message may include the device model information corresponding to device A, the latest version information corresponding to device A, and the network address corresponding to the upgrade file in CloudA. In addition, the subscription notification message may be sent by CloudA based on the first subscription upgrade information request, which includes the device model and CloudB's ID information. Based on the device model, CloudA can monitor the existence of a new update file for the device of that model, determine the upgrade file corresponding to the device model, and the upgrade file address (manufacturer upgrade server address) corresponding to the upgrade file, and send the subscription notification message to CloudB.

[0241] Device A receives the latest version information contained in the upgrade message, compares the latest version information with the current version information of device A, and confirms that the device is in the upgrade confirmation state.

[0242] Among them, when the information of the latest version is the same as the information of the current version of device A, it means that device A is at the latest version, so the device does not need to be upgraded; when the information of the latest version is different from the information of the current version of device A, it means that device A is not the latest version, and device A is set to the confirmed upgrade status.

[0243] S911: Device A obtains the upgrade file from CloudB.

[0244] Among them, device A can send a file acquisition request (second file acquisition request) to CloudB based on the storage address of the upgrade file on CloudB in the upgrade message pushed by CloudB; when CloudB receives the file acquisition request sent by device A, it sends the upgrade file to device A.

[0245] S912: When the device upgrade is complete, update the device version information to CloudB.

[0246] After device A is upgraded according to the upgrade file, it sends the updated version information corresponding to the upgrade completion to CloudB. CloudB receives the updated version information and updates the version information corresponding to device A. When CloudB receives the subscription notification message for the next upgrade file issued by CloudA, the next round of updates begins.

If CloudB has subscribed to the upgrade information corresponding to the device model from CloudA, that is, CloudB already has the upgrade information corresponding to the device model issued by CloudA, Device A can directly send a request to CloudB for an update. If CloudB has not subscribed to the upgrade information corresponding to the device model from CloudA, CloudB cannot instruct Device A to complete the device upgrade, and therefore CloudB needs to complete further information exchange with CloudA.

Cloud A receives the device model information in the subscription upgrade request, identifies the corresponding upgrade file based on the device model information, and generates the corresponding access credential based on the upgrade file.

[0256] S1006: After receiving the first subscription upgrade information request sent by CloudB, CloudA sends a first subscription upgrade information response message to CloudB.

[0257] CloudB and CloudA may communicate via an IMS network. The first subscription upgrade information response message may be a 200 OK response message sent upon receipt of a message via the IMS network, indicating that CloudA's server has received the first subscription upgrade information request sent by CloudB. The response message may include an access credential generated by CloudA, wherein the access credential is generated based on the device model, i.e., one access credential corresponds to each device model.

[0258] S1007, CloudA sends a subscription notification message (notification message) to CloudB.

[0271] The first upgrade file response may be generated by Cloud A using the access credentials. Cloud A receives the second file retrieval request sent by Cloud B, determines the upgrade file corresponding to the access credentials based on the access credentials in the second file retrieval request, and sends the upgrade file to Cloud B using the first upgrade file response.

[0272] S1014 , CloudB sends a second upgrade file response to device A.

[0273] After CloudB receives the first upgrade file response from CloudA, it obtains the upgrade file from the first upgrade file response, determines the device A corresponding to the upgrade file based on the first file acquisition request, and sends the upgrade file to device A.

[0277] Please refer to Figure 11 , which is a schematic diagram of a device upgrade control flow provided by an exemplary embodiment of the present application. Figure 11 As shown, taking the first cloud platform and the second cloud platform as servers as an example, the above Figure 7In the solution shown, the data transmission process between the terminal and the first cloud platform and the second cloud platform is as follows:

[0278] S1101, product access authentication and access. Device A (client device) passes the product access authentication of CloudB (first cloud platform) and connects to CloudB.

[0279] S1102: CloudB obtains information such as the model, manufacturer, manufacturer upgrade server address, and current version of device A. This information may be obtained by CloudB sending a request to device A, or may be sent by device A to CloudB during the product access authentication process with CloudB.

[0280] S1103, CloudB confirms whether the device of this model has subscribed to the upgrade information on the product upgrade server.

[0281] The device model is the device model corresponding to Device A, and the product upgrade server is CloudA (the second cloud platform) corresponding to Device A. If CloudB has subscribed to the upgrade information corresponding to the device model from CloudA, that is, CloudB already has the upgrade information corresponding to the device model issued by CloudA, Device A can directly send a request to CloudB for an update. If CloudB has not subscribed to the upgrade information corresponding to the device model from CloudA, CloudB cannot instruct Device A to complete the device upgrade, and therefore CloudB needs to complete further information exchange with CloudA.

[0282] S1104, CloudB sends a first subscription upgrade information request to CloudA.

[0283] The first subscription upgrade information request includes the device model and ID information of CloudB.

[0284] S1105 , after receiving the subscription upgrade request sent by CloudB, CloudA generates an access token (AccessToken) and saves the corresponding relationship between the ID of CloudB and the access token.

[0285] The access credential is generated based on the device model information in the subscription upgrade request sent by Cloud B. Cloud A receives the device model information in the subscription upgrade request, identifies the corresponding upgrade file based on the device model information, and generates the corresponding access credential based on the upgrade file.

[0286] S1106: After receiving the first subscription upgrade information request sent by CloudB, CloudA sends a first subscription upgrade information response message to CloudB.
