[0001] This application relates to the technical field of terminals, and in particular, to a device management method, a communication system, and related devices. Background Art

[0002] Currently, when a user wants to control a target device to perform related tasks through an electronic device, the user needs to first download a third-party application developed by the manufacturer of the target device, then open the third-party application, add and configure the target device in the third-party application, and subsequently also needs to use the third-party application to control the target device. In this way, the steps of adding and using the target device on the electronic device are relatively complex, it is difficult to manage the target device, and the efficiency of using the target device is affected. Summary of the Invention

[0003] This application provides a device management method, a communication system, and related devices, which can facilitate the first electronic device to manage other devices that do not log in to the cloud account logged in on the first electronic device.

[0004] In a first aspect, this application provides a device management method, which is applied to a first electronic device on which a cloud account is logged in; the method includes: the first electronic device connects to a first local area network and saves the network name and network password of the first local area network; the first electronic device receives a first message sent by the second electronic device, the second electronic device does not log in to the cloud account, and the first message includes the device information and a network configuration status identifier of the second electronic device, and the network configuration status identifier is used to indicate that the second electronic device does not store the network configuration information of the local area network; in response to receiving the first message, the first electronic device sends first network configuration information to the second electronic device, where the first network configuration information includes the network name and network password of the first local area network, and the first network configuration information is used to instruct the second electronic device to connect to the first local area network; after the first electronic device searches for the second electronic device through the first local area network, the first electronic device sends a proxy registration request to the cloud server, and the proxy registration request carries the device information of the second electronic device and the cloud account, and the proxy registration request is used to request the cloud server to bind the device information of the second electronic device to the cloud account.

[0005] Through a device management method provided by an embodiment of this application, when the first electronic device logs in to a cloud account and the second electronic device does not log in to the cloud account, the first electronic device can, after configuring the second electronic device to connect to the local area network where the first electronic device is located, through negotiation with the cloud server, bind the device information of the second electronic device to the cloud account logged in on the first electronic device. In this way, it can facilitate the first electronic device to manage other devices that do not log in to the cloud account logged in on the first electronic device.

[0006] Among them, the cloud server may store a device list corresponding to the cloud account, and the device information of all devices logged in or bound to the cloud account may be recorded in the device list corresponding to the cloud account. The cloud server can manage and update the status information of all devices in the device list corresponding to the cloud account, and can synchronize the status information of all devices in the device list to the devices logged in to the cloud account. In this way, the devices logged in to the cloud account can view the status of the second electronic device or call the second electronic device.

[0007] In a possible implementation, the method further includes: the first electronic device receives a binding success response sent by the cloud server, and the binding success response is used to indicate that the cloud server has successfully bound the device information of the second electronic device to the cloud account; after the first electronic device receives the binding success response sent by the cloud server, the first electronic device receives a first operation of the user to open the first interface; in response to the first operation, the first electronic device displays the first interface, and displays options of multiple devices on the first interface, and the multiple devices are logged in or bound to the cloud account, and the multiple devices include the first electronic device and the second electronic device.

[0008] In this way, the user can quickly view or call the second electronic device in the first interface (for example, the intelligent connection interface of the control center) displayed on the first electronic device.

[0009] In a possible implementation, the step of displaying the first interface in response to the first operation includes: in response to the first operation, obtaining the status information of the second electronic device; if the status information of the second electronic device is an online state, the first electronic device displays the first interface and displays an option of the second electronic device on the first interface.

[0010] In a possible implementation, after the first electronic device searches for the second electronic device through the first local area network, the first electronic device sends a proxy registration request to the cloud server, including: after the first electronic device searches for the second electronic device through the first local area network, according to the device information of the second electronic device, determining whether the second electronic device is in the binding whitelist and is not bound to the cloud account, and the binding whitelist includes one or more devices allowed to be bound to the cloud account logged in on the first electronic device; if the second electronic device is in the binding whitelist and is not bound to the cloud account, sending a proxy registration request to the cloud server.

[0011] In this way, when the second electronic device is not logged in to the cloud account and is not bound to the cloud account and the second electronic device has the permission to bind to the cloud account, the device information of the second electronic device can be bound to the cloud account, improving the security of the devices logged in or bound under the cloud account.

[0012] In a possible implementation, after the first electronic device receives the successful binding response sent by the cloud server, the method further includes: the first electronic device detects that the second electronic device is in an online state through the first local area network; the first electronic device sends the online state of the second electronic device and the device information of the second electronic device to a third electronic device logged in with the cloud account through the cloud server.

[0013] In this way, after the first electronic device binds the device information of the second electronic device with the cloud account, it can synchronize the status information of the second electronic device to other devices logged in with the cloud account, so that other devices logged in with the cloud account can view the status of the second electronic device or call the second electronic device.

[0014] In a possible implementation, after the first electronic device sends the proxy registration request to the cloud server, the method further includes: the first electronic device receives a second operation by the user to unbind the second electronic device from the cloud account; in response to the second operation, the first electronic device sends an unbinding notice to the cloud server, and the unbinding notice carries the device information of the second electronic device and the cloud account, and the unbinding notice is used to notify the cloud server to unbind the device information of the second electronic device from the cloud account.

[0015] Wherein, after the cloud server unbinds the device information of the second electronic device from the cloud account, it can delete the device information of the second electronic device in the device list corresponding to the cloud account. In this way, the devices logged in with the cloud account cannot obtain the status information of the second electronic device through the cloud server.

[0016] In a possible implementation, after the first electronic device sends the unbinding notice to the cloud server, the method further includes: the first electronic device receives an unbinding response sent by the cloud server, and the unbinding response is used to indicate that the cloud server has unbound the device information of the second electronic device from the cloud account; the first electronic device receives a first operation by the user to open the first interface; in response to the first operation, the first interface is displayed, and options of one or more devices are displayed on the first interface, and the one or more devices are logged in or bound to the cloud account, wherein the one or more devices include the first electronic device but do not include the second electronic device.

[0017] In this way, after the device information of the second electronic device is unbound from the cloud account, the first electronic device does not display the option of the first electronic device on the first interface.

[0018] In a possible implementation, the second electronic device is a printer; the method further includes: when the first electronic device displays an option of the second electronic device on the first interface, the first electronic device receives a third operation from the user for the option of the second electronic device; in response to the third operation, the first electronic device controls the second electronic device to perform a printing task.

[0019] In this way, after binding the device information of the printer to the cloud account, the user can quickly call the printer to perform a printing task by opening the first interface of the first electronic device (for example, the intelligent connection interface in the control center).

[0020] In a possible implementation, the first electronic device controls the second electronic device to perform a printing task, which specifically includes: the first electronic device receives a target file and target printing parameters selected by the user; in response to receiving the target file and target printing parameters selected by the user, the first electronic device sends the target printing parameters and the target file to the second electronic device through the first local area network, where the target file and target printing parameters are used to trigger the second electronic device to print the target file with the target printing parameters.

[0021] In a possible implementation, after the first electronic device controls the second electronic device to perform a printing task, the method further includes: the first electronic device sends configuration information to a third electronic device through the cloud server, the third electronic device logs in to the cloud account, and the configuration information includes a first parameter and the target printing parameters; wherein, the configuration information is used to instruct the third electronic device to set the initial printing parameters on the third electronic device to the target printing parameters, and the first parameter is used to grant the third electronic device the permission to call the second electronic device to perform printing.

[0022] In this way, devices logged in to the cloud account can share the configuration information of the printer with each other, so that when the user calls the printer on different devices, there is no need to repeatedly manually set the printing parameters of the printer.

[0023] In a possible implementation, the second electronic device is a printer. The first electronic device includes a control center, a shared service management framework, a printing service framework, and a distributed printing service. In response to the first operation, the first electronic device displays a first interface and shows options of multiple devices on the first interface, including: in response to the first operation, the control center sends a call request to the shared service management framework, and the call request is used to call the shared service management framework; the shared service management framework initializes one or more shared services, where the one or more shared services include the printing shared service; after the printing shared service is initialized, it registers a device discovery callback with the distributed printing service; after the distributed printing service registers the device discovery callback, when it discovers the second electronic device, it determines the status information of the second electronic device as the online status; the distributed printing service sends a device discovery notification to the printing shared service, and the device discovery notification carries the online status of the second electronic device; after receiving the device discovery notification, the printing shared service registers with the shared service management framework and returns the online status of the printer to the shared service management framework; after receiving the registration of the printing shared service, the shared service management framework obtains the online status of the second electronic device; after obtaining the online status of the second electronic device, the shared service management framework sends the online status of the second electronic device to the control center; after obtaining the online status of the second electronic device, the control center displays the first interface and shows the options of the first electronic device and the options of the second electronic device on the first interface.

[0024] In a possible implementation, the second electronic device is a printer; the first electronic device includes a printing assistant, an ecological access framework, and a device management service. The first electronic device sends a proxy registration request to the cloud server, including: the printing assistant sends a binding request to the device management service, and the binding request carries the device information of the second electronic device; in response to receiving the binding request, the device management service sends a proxy binding request to the ecological access framework, and the proxy binding request carries the device information of the printer and the cloud account; after receiving the proxy binding request, the ecological access framework sends the proxy registration request to the cloud server.

[0025] In a second aspect, the present application provides an electronic device, which is a first electronic device and includes one or more processors and one or more memories; wherein, the one or more memories are coupled to the one or more processors, and the one or more memories are used to store computer program code, and the computer program code includes computer instructions.

[0048] Next, the technical solutions in the embodiments of the present application will be clearly and elaborately described with reference to the accompanying drawings. Among them, in the description of the embodiments of the present application, unless otherwise specified, " / " means "or". For example, A / B may represent A or B; "and / or" in the text is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality of" means two or more than two.

[0049] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and should not be construed as implying or suggesting relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0050] The architecture of a communication system provided in the embodiments of the present application will be introduced below.

[0051] Figure 1 The schematic diagram of the architecture of a communication system 10 provided in the embodiments of the present application is shown.

[0052] As Figure 1 shown, the communication system 10 may include an electronic device 101, an electronic device 102, a printer 200, a wireless access device 300, and a cloud server 400.

[0053] Among them, the electronic device 101 may establish a connection with the cloud server 400. The electronic device 102 may establish a connection with the cloud server 400. Therefore, the electronic device 101 may communicate with the electronic device 102 through the cloud server 400.

[0054] The electronic device 101 may also establish a Wi-Fi connection with the wireless access device 300. The printer 200 may establish a Wi-Fi connection with the wireless access device 300. Therefore, the electronic device 101 may communicate with the printer 200 through the wireless access device 300.

[0055] The electronic device 101 and the electronic device 102 may both log in to the same designated cloud account, and the printer 200 does not log in to the designated cloud account. The electronic device 101 and the electronic device 102 may access the cloud server 400 through the logged-in cloud account.

[0056] It should be noted that the printer 200 in the above communication system 10 may also be replaced with other types of devices (such as speakers, cameras, etc.), which is not limited herein.

[0057] In the embodiments of the present application, the electronic device 101 may be referred to as the first electronic device, the printer 200 may be referred to as the second electronic device, and the electronic device 102 may be referred to as the third electronic device.

[0058] The trust ring involved in the embodiments of the present application will be introduced below.

[0059] Since multiple devices (e.g., electronic device 101 and electronic device 102) can establish connections with the cloud server 400 by logging in to the same specified cloud account. Multiple devices can achieve mutual calls between multiple devices through the cloud server 400. Due to the mutual calls between multiple devices that have logged in to the specified cloud account, these multiple devices form a mutually trusted system, and this mutually trusted system can be referred to as a trust ring.

[0060] However, some devices do not support logging in to cloud accounts. For example, the printer 200 has no input device, and the printer 200 cannot receive the cloud account and password manually input by the user. Another example is that the printer 200 is produced by a third manufacturer and does not belong to the same manufacturer as the multiple devices that have logged in to the specified cloud account above. Therefore, the printer 200 does not support logging in to the specified cloud account.

[0061] In this way, a device that has not logged in to the specified cloud account (such as the printer 200) is difficult to trust the multiple devices that have logged in to the specified cloud account above, and thus cannot join the trust ring of the specified cloud account by logging in to the specified cloud account.

[0062] Therefore, in the embodiments of the present application, a device management method is provided. A cloud account (e.g., a specified cloud account) is logged in on a first electronic device (e.g., electronic device 101). The cloud account is not logged in on a second electronic device (e.g., printer 200). After the first electronic device configures the second electronic device to join the local area network where the first electronic device is located, the device information of the second electronic device and the cloud account can be sent to the cloud server. The cloud server can bind the device information of the second electronic device with the cloud account.

[0063] Since the device information of the second electronic device is bound to the cloud account, the first electronic device can synchronize the status information and configuration information of the second electronic device to other devices that have logged in to the cloud account through the cloud server. In this way, the second electronic device can trust the devices that have logged in to the cloud account, that is, the second electronic device joins the trust ring of the cloud account.

[0064] In the embodiments of the present application, devices within the same trust ring log in to or are bound to the same cloud account. For example, both the electronic device 101 and the electronic device 102 log in to the specified cloud account, and the printer 200 is bound to the specified cloud account.

[0065] The following exemplarily introduces the process of binding the device information of the printer 200 with the specified cloud account in the smart space application on the electronic device 101 in the embodiments of the present application.

[0066] Figures 2A - 2SThe figure shows a schematic diagram of an interface for binding a printer to a specified cloud account in the smart space application provided in the embodiments of the present application.

[0067] As Figure 2A shown, the electronic device 101 can display a desktop 310. Among them, a page with application icons is displayed on the desktop 310, and this page includes multiple application icons (for example, weather application icon, stock application icon, calculator application icon, settings application icon 314, mail application icon, gallery application icon 313, music application icon, video application icon, browser application icon, smart space application icon 312, etc.). In the upper part area of the desktop 310, a status bar 311 is displayed, and the status bar 311 can include: one or more signal strength indicators of mobile communication signals (also known as cellular signals), battery status indicator, time indicator, Wi-Fi signal indicator, and so on.

[0068] The electronic device 101 can receive an operation (such as a click) of the user on the smart space application icon 312. In response to this operation, the electronic device 101 can display as Figure 2B shown the smart space application interface 320.

[0069] As Figure 2B shown, in the smart space application interface 320, an add control 323 and service cards of one or more devices (for example, a service card 321 of a TV and a service card 322 of a speaker) can be displayed. Among them, a specified cloud account is logged in to the smart space application of the electronic device 101.

[0070] The electronic device 101 can receive an operation (such as a click) of the user on the add control 323. In response to this operation, the electronic device 101 can display as Figure 2C shown a menu 324.

[0071] As Figure 2C shown, the menu 324 can include an add device control 325. The electronic device 101 can receive an operation (such as a click) of the user on the add device control 325. In response to this operation, the electronic device 101 can display as Figure 2D shown an add device interface 330.

[0072] As Figure 2DAs shown, the add device interface 330 can display devices searched by the electronic device 101 through short-range communication technologies (such as Wi-Fi, Bluetooth, etc.). Among them, after the electronic device 101 searches for the printer 200 through short-range communication technology, the electronic device 101 can display a device option 331 and a connection control 332 on the add device interface 330. Among them, the device name of the printer 200 (such as "Printer P1") is displayed on the device option 331. The connection control 332 can be used to trigger the electronic device 101 to configure the printer 200 to connect to the local area network where the electronic device 101 is located.

[0073] The electronic device 101 can receive the user's operation on the connection control 332 (such as a click). In response to this operation, the electronic device 101 can send the network name and network password of the local area network connected by the electronic device 101 to the printer 200, so as to configure the printer 200 to use the network name and network password of the local area network and connect to the local area network connected by the electronic device 101.

[0074] As Figure 2E shown, after the printer 200 is connected to the local area network connected by the electronic device 101, the electronic device 101 can display a service card 326 of the printer 200 in the smart space application interface 320.

[0075] Optionally, after the electronic device 101 configures the printer 200 to use the network name and network password of the local area network and connects to the local area network connected by the electronic device 101, the electronic device 101 can send the device information of the printer 200 and the specified cloud account logged in on the electronic device 101 to the cloud server 400. After receiving the device information of the printer 200 and the specified cloud account, the cloud server 400 can bind the device information of the printer 200 with the specified cloud account. In this way, the printer 200 can be added to the trust ring of the specified cloud account.

[0076] The electronic device 101 can receive the user's input on the service card 326 (such as a click). In response to this input, the electronic device 101 can start the print assistant and display a print assistant interface 340 as Figure 2F shown.

[0077] As Figure 2FAs shown, the print assistant interface 340 may include a current printer settings bar 341 and one or more print options. Among them, device information (e.g., "PrinterP1") and status information (e.g., "idle status") of the printer 200 are displayed on the current printer settings bar 341. The one or more print options may include a wrong-question print option, a test paper restoration print option, a handwritten newspaper print option, an origami print option, a document print option, a picture print option 342, a scan option, a large picture print option, and a regional data print option, etc.

[0078] The electronic device 101 may receive an input (e.g., a click) from the user for the picture print option 342. In response to this input, the electronic device 101 may display a picture selection interface 350 as Figure 2G shown.

[0079] As Figure 2G shown, the picture selection interface 350 may display thumbnails of one or more pictures locally stored in the electronic device 101 (including the thumbnail 351).

[0080] The electronic device 101 may receive an input (e.g., a click) from the user for the thumbnail 351. In response to this input, the electronic device 101 may display the print interface 360 as Figure 2H shown above.

[0081] As Figure 2H shown, the print interface 360 may include a print preview area 361, one or more print parameter setting options, and a start print control 367. Among them, the print preview area 361 may be used to display the printing effect of the picture 362 corresponding to the above thumbnail 351. The one or more print parameter setting options may include a print copy number setting option 363, a single-sided / double-sided print setting option 364, a paper size setting option 365, and a color print setting option 366, etc. Among them, the print copy number setting option 363 can be used to set the number of copies for the printer 200 to print the picture 362. The single-sided / double-sided print setting option 364 can be used to set whether to print the picture 362 on a single side or on both sides. The paper size setting option 365 can be used to set the size for the printer 200 to print the picture 362. The color print setting option 366 is used to set whether the printer 200 prints the picture 362 in color or in black and white. The start print control 367 can be used for the electronic device 101 to trigger the printer 200 to print the picture 362 with the print parameters set by the user.

[0082] Among them, the electronic device 101 can determine the target printing parameters of the picture 362 according to the user's operations in the above-mentioned printing interface 360. The electronic device 101 can receive and respond to the user's operation on the start printing control 367, and send the picture 362 and the target printing parameters set by the user (for example, 5 copies, single-sided printing, paper size A4, black and white printing, etc.) to the printer 200. The electronic device 101 can control the printer 200 through the local area network to print the picture 362 with the target printing parameters.

[0083] As Figure 2I shown, during the process of the printer 200 printing the picture 362 with the target printing parameters, the printer 200 can send the printing status to the electronic device 101. After receiving the printing status, the electronic device 101 can display the printing interface 370, where the printing interface 370 can include a print preview area 371, a printing status prompt 372, and a stop printing control 373. The print preview area 371 can be used to display the printing effect of the above-mentioned picture 362. The printing status prompt 372 can be used to prompt the current printing status of the printer. For example, the printing status prompt 372 can be "Printing the 1st copy / (total 5 copies)". The stop printing control 373 can be used to trigger the electronic device 101 to control the printer 200 to stop the current printing task through the electronic device 102.

[0084] After the printer 200 finishes printing the picture 362 with the target printing parameters, the printer 200 can send the printing completion information to the electronic device 101.

[0085] As Figure 2J shown, after receiving the printing completion information, the electronic device 101 can display the printing interface 380, where the printing interface 380 can include a print preview area 381, a printing completion prompt 382, a completion control 383, and a continue printing control 384. The print preview area 381 can be used to display the printing effect of the above-mentioned picture 362. The printing completion prompt 382 can be used to prompt that the printer has completed the printing task. The completion control 383 can be used to exit the printing interface 380. The continue printing control 384 can be used to trigger the electronic device 101 to continue to select files for the printer 200 to print.

[0086] The electronic device 101 can receive the user's operation on the completion control 383 (for example, click), and in response to this operation, the electronic device 101 can display a binding pop-up window 390 as Figure 2K shown.

[0087] As Figure 2KAs shown in the figure, the binding pop-up window 390 may include the device name 391 of the printer 200 (for example, PrinterP1), a binding prompt 392, a confirmation control 393, and a cancellation control 394. Among them, the binding prompt 392 can be used to prompt the user whether to bind the printer 200 to the specified cloud account. For example, the binding prompt 392 can be a text prompt "Do you want to bind the printer through the Honor account trust authentication?" The confirmation control 393 can be used to trigger the electronic device 101 to request the cloud server 400 to bind the device information of the printer 200 to the specified cloud account. The cancellation control 394 can be used to trigger the electronic device 101 to cancel the request to the cloud server 400 to bind the device information of the printer 200 to the specified cloud account.

[0088] The electronic device 101 may receive an operation (such as a click) of the user on the confirmation control 393. In response to this operation, the electronic device 101 may send the device information of the printer 200 and the specified cloud account to the cloud server. Then, the cloud server may bind the device information of the printer 200 to the specified cloud account, thereby adding the printer 200 to the trust ring corresponding to the specified cloud account. Optionally, the electronic device 101 may also add the device information of the printer 200 to the bound list stored locally.

[0089] In a possible implementation, the electronic device 101 may receive and respond to an operation (such as a click) of the user on the completion control 383, and send the device information of the printer 200 and the specified cloud account to the cloud server 400. After receiving the device information of the printer 200 and the specified cloud account, the cloud server 400 may bind the device information of the printer 200 and the specified cloud account. In this way, the printer 200 can be added to the trust ring of the specified cloud account.

[0090] As Figure 2L shown, the electronic device 101 may receive a sliding operation of the user at the top of the screen (such as sliding down from the top of the screen). In response to this operation, the electronic device 101 may display the control center interface 410 as Figure 2M shown.

[0091] As Figure 2M shown, the control center interface 410 may include one or more function controls (such as a wireless local area network (WLAN) switch control, a Bluetooth switch control, a low battery mode switch control, a brightness adjustment control, a sound adjustment control), a music control card, and a smart interconnection control card 411.

[0092] The electronic device 101 may receive an operation (such as a click) of the user on the smart interconnection control card 411. In response to this operation, the electronic device 101 may display the smart interconnection interface 420 as Figure 2N shown.

[0093] As shown Figure 2N in the figure, the intelligent interconnection interface 420 may include a device option 421 of the electronic device 101, an avatar 425 designating a cloud account, and a deletion control 424. After the electronic device 101 obtains the online information of other devices within the trust ring, it may display the device options of other devices logged in or bound to the designated cloud account in the intelligent interconnection interface 420. Other devices logged in or bound to the designated cloud account may include the electronic device 102 and the printer 200. For example, after the electronic device 101 discovers that the printer 200 is online, it may display the device option 422 of the printer 200 on the intelligent interconnection interface 420. Optionally, when the electronic device 101 discovers through the cloud server 400 that the electronic device 102 is online, it may display the device option 423 of the electronic device 102 on the intelligent interconnection interface 420. The deletion control 424 can be used to trigger the electronic device 101 to request the cloud server 400 to unbind the device information of the device selected by the user from the designated cloud account, so as to delete the device selected by the user from the trust ring of the designated cloud account.

[0094] As shown Figure 2O in the figure, the electronic device 101 may receive a drag operation in which the user drags the device option 422 to the area where the device option 421 is located.

[0095] As shown Figure 2P in the figure, in response to the drag operation in which the user drags the device option 422 to the area where the device option 421 is located, the electronic device 101 may retreat to display the desktop 310 and display a print capsule 431 on the display screen. The display screen of the electronic device 101 is a perforated screen. Generally, a front camera is placed at the perforation position of the display screen, and the front camera of the display screen may be at the top of the display screen. To make full use of the display area of the display screen, the electronic device 101 displays the print capsule 431 around the perforation position at the top of the display screen. Among them, the perforation position of the display screen may be located in the middle area of the print capsule 431. The non-middle area of the print capsule 431 may display a print icon, print words, and the device manufacturer, device model (for example, Printer P1) or device identifier of the printer 200, etc. Since the display color of the perforation position is black, the background color of the print capsule 431 may also be adjusted to black, so that it is difficult for the user to discover the perforation position of the display screen. Among them, the print capsule 431 may be floatingly displayed on the upper layer of other interfaces. The print capsule 431 can be used to call a print assistant to print the files in the interface currently displayed on the electronic device 101. Among them, the files include any one of documents, pictures, videos, tables, PPTs, etc.

[0096] The electronic device 101 can receive a user's operation (e.g., click) on the gallery application icon 313 in the desktop 310. In response to the user's operation, the electronic device 101 can display a gallery application interface 440 as shown Figure 2Q below.

[0097] As shown Figure 2Q below, the gallery application interface 440 can include thumbnails of one or more pictures, such as thumbnail 441. Among them, when the electronic device 101 displays the gallery application 440, it can also display the above-mentioned printing capsule 431.

[0098] The electronic device 101 can receive a user's operation on the thumbnail 441. In response to this operation, the electronic device 101 can display a picture browsing interface 450 as shown Figure 2R below.

[0099] As shown Figure 2R below, when the electronic device 101 displays the picture browsing interface 450, it can display the above-mentioned printing capsule 431. Among them, the picture browsing interface 450 can include a picture 451. Optionally, the picture browsing interface 450 can further include a menu 452, and the menu 452 can include sharing controls, favorite controls, editing controls, deletion controls, more controls.

[0100] The electronic device 101 can receive a user's operation (e.g., click) on the printing capsule 431. In response to this operation, as shown Figure 2S below, the electronic device 101 can switch the printing capsule 431 to a printing notification bar 432 and display it at the top of the display screen.

[0101] As shown Figure 2S below, the printing notification bar 432 can include the file name of the file currently opened by the user and a printing control 433. Among them, the file currently opened by the user can be the picture 451. Therefore, the file name "IMG_2023 / 9 / 20_1.JPG" of the picture 451 can be displayed in the printing notification bar 432.

[0102] The electronic device 101 can receive a user's operation (e.g., click) on the printing control 433. In response to this operation, the electronic device 101 can display a printing interface 360 as shown above Figure 2H below. For the subsequent printing operation process, reference can be made to the embodiment shown above Figures 2H - 2J below, and details will not be described herein again.

[0103] In the embodiments of the present application, the above-mentioned intelligent interconnection interface 420 can be referred to as the first interface, and the user's operation on the intelligent interconnection control card 411 can be referred to as the first operation. The above-mentioned dragging operation of dragging the device option 422 to the area where the device option 421 is located can be referred to as the third operation.

[0104] In a possible implementation, if the electronic device 101 does not receive an operation from the user on the printing capsule 431 after a certain period of time (e.g., 10 seconds) has elapsed since the printing capsule 431 was displayed, the display of the printing capsule 431 is exited.

[0105] In a possible implementation, if, after the electronic device 101 displays the printing notification bar 432, it receives a click from the user outside the printing notification bar 432, the electronic device 101 can switch the printing notification bar 432 back to display the printing capsule 431 at the top of the display screen.

[0106] In some application scenarios, the printer 200 can be a newly unconfigured printer. After the printer 200 is powered on or enters the network configuration mode, the printer 200 can send a broadcast message (which can be referred to as the first message), where the broadcast message includes the device information of the printer 200 and a network configuration status identifier. The network configuration status identifier is used to indicate that the printer 200 does not store the network configuration information of the local area network, that is, it is in an unconfigured state. After the electronic device 101 receives the broadcast message sent by the printer 200, it can obtain the device information of the printer 200 from the broadcast message and display a discovery window, which is used to prompt the user whether to connect the printer 200 to the local area network where the electronic device 101 is located. After the electronic device 101 receives an operation from the user to connect the printer 200 to the first local area network where the electronic device 101 is located, it can obtain the network name and network password of the first local area network stored locally on the electronic device 101 through the smart space application. The electronic device 101 can send the first network configuration information to the printer 200 through the smart space application, where the first network configuration information includes the network name and network password of the first local area network. After the printer 200 receives the first network configuration information, it can connect to the local area network to which the electronic device 101 is connected through the network name and network password of the first local area network. After the electronic device 101 searches for the printer 200 through the first local area network, it means that the printer 200 has successfully connected to the first local area network. At this time, the electronic device 101 can request the cloud server 400 to bind the device information of the printer 200 and the specified cloud account logged in on the electronic device 101. In this way, the printer 200 is added to the trust ring of the specified cloud account.

[0107] Figures 3A - 3C Shows a schematic diagram of an interface for binding the device information of the printer 200 with a specified cloud account in the smart space application provided in the embodiments of the present application.

[0108] Exemplarily, such as Figure 3AAs shown, the electronic device 101 can display the desktop 310. Among them, after receiving the broadcast signal of the printer 200, the electronic device 101 can obtain the device information of the printer 200 from the broadcast signal and display the discovery window 460. Among them, the discovery window 460 includes the icon and name of the printer 200 (for example, PrinterP1), the connection control 461 and the cancel control 462. Among them, the connection control 461 can be used to trigger the electronic device 101 to configure the network for the printer 200, and the cancel control 462 can be used to trigger the electronic device 101 to cancel the network configuration for the printer 200.

[0109] As Figure 3B shown, the electronic device 101 can receive and respond to the user's operation (such as clicking) on the above-mentioned connection control 461, and display the intelligent space application interface 320 and the network configuration pop-up window 470. Among them, the network configuration pop-up window 470 can include the icon and name of the printer 200 (for example, Printer P1), the network configuration prompt message 471, the allow control 472 and the manual input control. For example, the network configuration prompt message 471 can be "Do you want to synchronize the connected local area network (Wi-Fi name and password) to the printer (Printer P1) for network configuration with one key?". The allow control 472 can be used to trigger the electronic device 101 to obtain the network name and network password of the local area network connected by the electronic device 101 through the intelligent space application, and send the network name and network password to the printer 200. The manual input control can be used to trigger the electronic device 101 to receive the network name and network password of the local area network input by the user, and send the network name and network password input by the user to the printer 200.

[0110] The electronic device 101 can receive and respond to the user's operation (such as clicking) on the above-mentioned allow control 472, obtain the network name and network password of the local area network connected by the electronic device 101 through the intelligent space application, and send the network name and network password to the printer 200. The printer 200 can connect to the local area network connected by the electronic device 101 according to the received network name and network password.

[0111] As Figure 3C shown, when the electronic device 101 searches for the printer 200 in the local area network, it can display the network configuration success pop-up window 480. The network configuration success pop-up window can be used to prompt the user that the printer 200 has been successfully network-configured. After the network configuration is successful, the electronic device 101 can display the service card 326 of the printer 200 in the intelligent space application interface 320. After successfully network-configuring the printer 200, the electronic device 101 can also request the cloud server 400 to bind the device information of the printer 200 and the specified cloud account. In this way, the printer 200 is added to the trust ring of the specified cloud account.

[0112] In some application scenarios, the printer 200 may be a new printer that is not connected to the network. The electronic device 101 can start the printing assistant through the settings application and search for the printer in the printing assistant for configuration. After the printer 200 is powered on or enters the network configuration mode, the printer 200 can send a broadcast message (which can be referred to as the first message). Among them, the broadcast message includes the device information of the printer 200 and a network configuration status identifier. The network configuration status identifier is used to indicate that the printer 200 does not store the network configuration information of the local area network, that is, it is in an unconfigured network state. After receiving the broadcast message sent by the printer 200, the electronic device 101 can obtain the device information of the printer 200 from the broadcast message and display that the printer 200 is unconfigured in the printing assistant interface. After the electronic device 101 receives the operation of the user to configure the printer 200, the electronic device 101 can send the first network configuration information to the printer 200 through the smart space application. The first network configuration information includes the network name and network password of the first local area network. After receiving the first network configuration information, the printer 200 can connect to the first local area network to which the electronic device 101 is connected through the network name and network password of the first local area network. When the electronic device 101 searches for the printer 200 through the first local area network, it means that the printer 200 has successfully connected to the first local area network. At this time, the electronic device 101 can request the cloud server 400 to bind the device information of the printer 200 and a specified cloud account. In this way, the printer 200 is added to the trust ring of the specified cloud account.

[0113] Figures 4A - 4G The figure shows a schematic diagram of an interface for calling the printer assistant in the settings application to bind the device information of the printer 200 with a specified cloud account provided in the embodiment of the present application.

[0114] As Figure 4A shown, the electronic device 101 can display the desktop 310. The text description of the desktop 310 can refer to the text part of the above Figure 2A shown embodiment and will not be elaborated here.

[0115] The electronic device 101 can receive an operation (such as a click) of the user on the settings application 314. In response to this operation, the electronic device 101 can display a settings interface 490 as Figure 4B shown.

[0116] Among them, the settings interface 490 may include one or more setting items. For example, one or more setting items may include a WLAN setting item, a Bluetooth setting item, a mobile network setting item, a more connection setting item 491, a desktop and wallpaper setting item, a display and brightness setting item, a sound and vibration setting item, a battery setting item, a system setting item, etc.

[0117] The electronic device 101 can receive a user's operation (such as a click) on more connection settings item 491. In response to this operation, the electronic device 101 can display, as Figure 4C shown, the more connection interface 510.

[0118] As Figure 4C shown, the more connection interface 510 can include a print settings item 511, an NFC settings item, a Honor Share settings item, a Honor Car Connect settings item, a wireless screen mirroring settings item, etc.

[0119] The electronic device 101 can receive a user's operation (such as a click) on the print settings item 511. In response to this operation, the electronic device 101 can display, as Figure 4D shown, the print interface 520.

[0120] As Figure 4D shown, the print interface 520 can include a print assistant start control 521.

[0121] The electronic device 101 can receive a user's operation (such as a click) on the print assistant start control 521. In response to this operation, the electronic device 101 can start the print assistant and display, as Figure 4E shown, the print assistant interface 530.

[0122] As Figure 4E shown, the print assistant interface 530 can include a printer display area 531 and an add control 532. Among them, the printer display area 531 can be used to display the printers 200 added by the electronic device 101. Since the electronic device 101 has not added a printer currently, the electronic device 101 can display an add prompt in the printer display area 531. For example, the add prompt can be "Multiple printers can be added". The add control 532 can be used to trigger the electronic device 101 to add a printer.

[0123] The electronic device 101 can receive a user's operation (such as a click) on the add control 532. In response to this operation, the electronic device 101 can display, as Figure 4F shown, the printer add interface 540.

[0124] As Figure 4FAs shown, when the electronic device 101 enters the printer addition interface 540, it can search for printers through short-range communication technologies (such as Bluetooth, Wi-Fi, etc.). The electronic device 101 can display the options corresponding to the searched printers in the printer addition interface 540. For example, when the electronic device 101 searches for the networked printer "PrinterA1" within the local area network, it can display the connection control 541 corresponding to the printer "Printer A1" in the available printer list of the printer addition interface 540. The electronic device 101 can receive a broadcast message sent by the printer 200, where the broadcast message includes the device information of the printer 200 (for example, the device name is "Printer P1") and a network configuration status identifier, and this network configuration status identifier is used to indicate that the printer 200 does not store the network configuration information of the local area network. Therefore, the electronic device 101 can display the connection control 542 corresponding to the printer 200 in the available printer list and display that the printer 200 is in an un-networked state.

[0125] The electronic device 101 can receive an operation (such as a click) from the user on the connection control 542. In response to this operation, the electronic device 101 can obtain the network name and network password of the local area network to which the electronic device 101 is connected from the local, and send the network name and network password to the printer 200. The printer 200 can connect to the local area network to which the electronic device 101 is connected according to the received network name and network password.

[0126] As Figure 4G shown, when the electronic device 101 obtains the online information of the printer 200 within the local area network, the electronic device 101 can display the status information 543 of the printer 200 (for example, idle) in the current printer list of the printer addition interface 540. Among them, after the electronic device 101 successfully configures the network for the printer 200, it can also request the cloud server 400 to bind the device information of the printer 200 and a specified cloud account. In this way, the printer 200 is added to the trust ring of the specified cloud account.

[0127] In some application scenarios, the printer 200 may be connected to the same local area network as the electronic device 101 through network configuration, but not bound to a specified cloud account. When the electronic device 101 displays the intelligent interconnection interface in the display control center, it can search for printers within the local area network. After the printer 200 is found, if it is determined that the printer 200 is bound to a specified cloud account, the electronic device 101 can display a binding pop-up window to prompt the user to bind the printer 200 to the specified cloud account, so that the printer 200 can be viewed or used in the intelligent interconnection interface of the control center. After receiving the user's operation to confirm the binding, the electronic device 101 can request the cloud server 400 to bind the device information of the printer 200 and the specified cloud account. In this way, the printer 200 is added to the trust ring of the specified cloud account.

[0128] Figures 5A - 5B FIG. shows a schematic diagram of an interface for adding the device information of the printer 200 and binding it to a specified cloud account provided in an embodiment of the present application in the control center.

[0129] As Figure 5A shown, after the electronic device 101 receives the user's operation (such as a click) on the intelligent interconnection control card 411 in the control center interface 410 shown above Figure 2M the electronic device 101 can first display the intelligent interconnection interface 420. The electronic device 101 can search for the online information of other devices within the trust ring corresponding to the specified cloud account through a short-range communication technology (such as Bluetooth, WiFi) or the cloud server.

[0130] As Figure 5B shown, since the specified cloud account is logged in on the electronic device 102, the electronic device 101 can obtain the online information of the electronic device 102 through the cloud server. Therefore, the electronic device 101 can display the device option 423 of the electronic device 102 on the intelligent interconnection interface 420. The electronic device 101 can also search for devices around that are not bound to the specified cloud account through a short-range communication technology (such as Bluetooth, WiFi). For example, when the electronic device 101 discovers the printer 200 through a short-range communication technology and the printer 200 is not bound to the specified cloud account, the electronic device 101 can display a list 550 of devices to be bound, where the list 550 of devices to be bound includes the device name 551 of the printer 200 and an add control 552. The add control 552 can be used to trigger the electronic device 101 to request the cloud server 400 to bind the device information of the printer 200 and the specified cloud account. The cancel control 553 can be used to trigger the electronic device 101 to cancel the request to the cloud server 400 to bind the device information of the printer 200 and the specified cloud account.

[0131] The electronic device 101 may receive an operation (such as a click) from the user on the add control 552. In response to this operation, the electronic device 101 sends the device information of the printer 200 and the specified cloud account to the cloud server 400, enabling the cloud server 400 to bind the device information of the printer 200 to the specified cloud account, thereby adding the printer 200 to the trust ring corresponding to the specified cloud account. The electronic device 101 may also add the device information of the printer 200 to the local list of devices in the ring.

[0132] After binding the device information of the printer 200 to the specified cloud account, when the electronic device 101 receives the online information of the printer 200, it may display the device options 422 of the printer 200 as described above on the intelligent interconnection interface 420. Figure 2N in the above-mentioned

[0133] Figures 5C - 5E FIG. shows a schematic diagram of an interface for unbinding the device information of a printer from a specified cloud account in a set of control centers provided in an embodiment of the present application.

[0134] As Figure 5C , after the electronic device 101 discovers that the printer 200 is online, it may display the device options 422 of the printer 200 on the intelligent interconnection interface 420. The electronic device 101 may receive an operation from the user to drag the device option 422 near the delete control 424.

[0135] As Figure 5D shown, in response to the operation of the user dragging the device option 422 near the delete control 424, the electronic device 101 may display a delete prompt box 560. The delete prompt box 560 may display a delete prompt 561, a confirmation control 562, and a cancel control 563. Among them, the delete prompt 561 is used to prompt the user whether to delete the printer 200 from the trust ring corresponding to the specified account. For example, the delete prompt 561 may be a text prompt "Whether to delete the XX printer Printer P1 from the trust ring". The confirmation control 562 can be used to trigger the electronic device 101 to delete the printer 200 from the trust ring corresponding to the specified account. The cancel control 563 can be used to trigger the electronic device 101 to cancel the deletion of the printer 200 from the trust ring corresponding to the specified account.

[0136] The electronic device 101 may receive an operation (such as a click) from the user on the confirmation control 562. In response to this operation, the electronic device 101 may request the cloud server to unbind the printer 200 from the specified account and delete the device information of the printer 200 from the local whitelist in the ring, thereby deleting the printer 200 from the trust ring corresponding to the specified account.

[0137] As Figure 5CAs shown in the figure, after the electronic device 101 deletes the printer 200 from the trust ring corresponding to the specified account, the device option 422 of the printer 200 can be cancelled from display on the intelligent interconnection interface 420.

[0138] In the embodiment of this application, the operation (such as clicking) of the user on the above confirmation control 562 can be referred to as a second operation.

[0139] The following introduces a software architecture of an electronic device provided in the embodiment of this application.

[0140] Figure 6 The figure shows a schematic diagram of a software architecture of an electronic device provided in the embodiment of this application.

[0141] As Figure 6 shown, the software architecture of the electronic device may include an application layer, a business middle platform, and a basic middle platform. Among them, the application layer may include a system interaction entry and a printing entry. The system interaction entry may include a control center. The printing entry may include a printing assistant, a smart space application, system settings printing, sharing printing, and third-party applications, etc.

[0142] The business middle platform may include a smart multi-modal human-computer interaction framework and a basic service framework. Among them, the smart multi-modal human-computer interaction framework may include a shared service management framework. The basic service framework may include a printing service.

[0143] The basic middle platform may include a trust ring (Magic Ring) framework. The trust ring framework may include a trust ring basic service and a system software and hardware resource sharing protocol component.

[0144] The trust ring basic service may include a printing sharing service. Among them, the printing sharing service may support functions such as the entry and exit of printers from the trust ring, printing device selection, printing management, and printing extension capabilities. The system software and hardware resource sharing protocol component may include a distributed printing service, a device management service, a far-field communication service, a data transmission service, an access networking (Nearby) service, a distributed call framework, and an ecological access framework (Magic Link).

[0145] The distributed printing service may include application programming interfaces (APIs) for one or more functions, a printing scheduling module, a near and far-field printing management module, an authorization management module, a protocol package shelf, third-party printing protocol packages, and Mopria protocol packages, etc. Among them, the one or more functions include status management, task management, device information management, device discovery, near-field connection, device authentication, and device configuration, etc.

[0146] The device management service can manage the device status, online / offline status, etc. of one or more devices within the trust ring. The far-field communication service can establish a communication connection with the far-field cloud server, thereby establishing a far-field transmission channel with the far-field communication services of other devices. The data transmission service can be called by the printing service to send file data on the far-field transmission channel or the near-field transmission channel. The nearby service can identify printers discovered via the near field and establish a near-field transmission channel with the printers. The distributed call framework can implement functions that can be called by other devices. The ecological access framework (Magic Link) can establish a communication connection with the device cloud server (e.g., a message queuing telemetry transport (MQTT) connection).

[0147] The system software and hardware resource sharing protocol component can provide a distributed printing protocol interface to the printing sharing service. Therefore, the printing sharing service can call the distributed printing service through the distributed printing protocol interface to complete printing functions such as printing device selection, printing management, and printing extension capabilities. The system software and hardware resource sharing protocol component can also provide call interfaces for functions such as the printer entering and leaving the trust ring, discovery, online / offline, etc. to the printing sharing service. Therefore, the printing sharing service can obtain the control of the printer entering and leaving the trust ring from the distributed printing service through the call interfaces for functions such as the printer entering and leaving the trust ring, discovery, online / offline, etc.

[0148] The trust ring basic sharing service can provide a call interface for the trust ring basic sharing service to the printing service. The printing service can provide a call interface for the printing service to the printing entry. The printing sharing service can register the printing sharing service with the shared service management framework. The shared service management framework can manage the shared services of multiple devices within the trust ring. Among them, the shared services of multiple devices within the trust ring can include the printing sharing service. The shared service management framework can obtain the online / offline status of the printer from the printing sharing service and send the online / offline status of the printer to the control center.

[0149] The control center can obtain the online / offline information of multiple devices within the trust ring from the shared service management framework. Among them, the online / offline information of multiple devices within the trust ring can include the online / offline information of the printer. Display device options of multiple devices entering the trust ring and the online / offline information of these multiple devices in the intelligent interconnection interface. Among them, the multiple devices in the trust ring can include printer 200, electronic device 101, electronic device 102, etc. Multiple devices in the same trust ring are logged in or bound to the same cloud account.

[0150] The following combines the above Figures 2A - 2S illustrated embodiments to specifically introduce the method flow of adding a printer in the intelligent space application.

[0151] Through the device management method provided in the embodiments of the present application, after the electronic device 101 uses the smart space to add and configure the printer 200 for printing, it can request the cloud server 400 to bind the device information of the printer 200 to a specified cloud account. In this way, the user can quickly call the printer 200 in the smart connection interface of the control center of the electronic device 101. Moreover, other devices logged in with the specified cloud account can receive the status information of the printer 200 and can also call the printer 200 for printing, which facilitates the user to use the same printer on different devices.

[0152] Figure 7 The flowchart shows a device management method provided in the embodiments of the present application.

[0153] As Figure 7 shown, this method can be applied to a communication system including an electronic device 101 and a cloud server 400. Among them, the electronic device 101 can include a smart space application, a device management service, an ecological access framework (Magic Link), a printing service, a printing assistant, etc. The cloud server 400 can include a device cloud server.

[0154] Among them, this method can include the following steps:

[0155] S701. The smart space application detects an operation in which the user selects the printer 200 for printing.

[0156] Among them, the operation in which the user selects the printer 200 for printing can be the operation on the service card 326 for the printer 200 in the above Figure 2E shown embodiment. For specific content, reference can be made to the above Figure 2E shown embodiment, which will not be elaborated here.

[0157] S702. The smart space application sends a printing request to the printing assistant. Among them, the printing request carries the device information of the printer 200.

[0158] Among them, the device information of the printer 200 includes the product identifier (product identifier, proID) of the printer 200 (for example, "P1"), the device identifier, the device name (for example, "Printer P1"), etc. Among them, the device identifier can include any one of a unique device identifier (unique device identifier, UDID), a MAC address, etc.

[0159] S703. The electronic device 101 displays a printing assistant interface.

[0160] For example, the printing assistant interface can refer to the above Figure 2FThe print assistant interface 340 in the illustrated embodiment will not be elaborated here.

[0161] S704. The print assistant detects that the user selects the target file in the print assistant interface.

[0162] For example, the operation of the user selecting the target file in the print assistant interface may refer to the above Figures 2F - 2G illustrated embodiment and will not be elaborated here.

[0163] S705. The print assistant displays the print interface.

[0164] For example, the print interface may refer to the print interface 360 in the above Figure 2H illustrated embodiment. For specific content, it may refer to the above Figure 2H illustrated embodiment and will not be elaborated here.

[0165] S706. The print assistant detects that it receives the target print parameters input by the user in the print interface and detects the user's operation of starting to print.

[0166] Among them, the user can select the target print parameters for the target print file in the print interface.

[0167] For example, the user's operation of starting to print may refer to the above Figure 2H illustrated embodiment. For the operation of the start print control 367, for specific content, it may refer to the above Figure 2H illustrated embodiment and will not be elaborated here.

[0168] S707. The print assistant sends a print task to the print service. Among them, the print task carries the target print parameters, the target file, and the device information of the printer 200.

[0169] S708. The print service controls the printer 200 to print the target file with the target print parameters.

[0170] Among them, the print service can call the protocol package shelf according to the device information of the printer 200 to load the target print protocol package matching the printer 200, and send the target print parameters and the target file to the printer 200 through the target print protocol package to control the printer 200 to print the target file with the target print parameters.

[0171] S709. The print service sends a print completion notification to the print assistant.

[0172] After the printer 200 finishes printing the target file with the target printing parameters, it can send a print completion message to the print service. The print completion message is used to notify that the printer 200 has completed printing the target file. After receiving the print completion message, the print service can send a print completion notice to the print assistant. The print assistant can display the print completion notice ( Figure 7 not reflected in), and the print completion notice is used to indicate that the printer 200 has completed printing the target file.

[0173] S710. The print assistant determines that the printer 200 is in the bound whitelist according to the device information of the printer 200.

[0174] Among them, the product identifiers of printers that can be added to the trust ring corresponding to the specified cloud account can be stored in the bound whitelist. Among them, after receiving the print completion notice, the print assistant can determine whether the product identifier of the printer 200 is stored in the bound whitelist. If the product identifier of the printer 200 is stored in the bound whitelist, the print assistant can determine that the printer 200 is in the bound whitelist. If the product identifier of the printer 200 is not stored in the bound whitelist, the print assistant can not perform the subsequent steps.

[0175] S711. The print assistant sends a binding judgment request to the device management service.

[0176] Among them, the device information of the printer 200 is carried in the binding judgment request. The binding judgment request can be used to request the device management service to judge whether the printer 200 has been bound to the specified cloud account.

[0177] S712. The device management service determines that the printer 200 is not bound to the specified cloud account according to the device information of the printer 200.

[0178] The bound device list of the specified cloud account can be stored in the device management service. The device management service can judge whether the device information of the printer 200 is included in the list of devices that have entered the ring. If the device information of the printer 200 is included in the bound device list, the device management service can determine that the printer 200 has been bound to the specified cloud account. If the device information of the printer 200 is not included in the bound device list, the device management service can determine that the printer 200 is not bound to the specified cloud account.

[0179] S713. The device management service returns a binding judgment result 1. The binding judgment result 1 is used to indicate that the printer 200 is not bound to the specified cloud account.

[0180] S714. The print assistant displays a binding pop-up window.

[0181] S715. The print assistant detects that the user authorizes the printer 200 to bind to the specified cloud account in the binding pop-up window.

[0182] Among them, the binding pop-up window can refer to the binding pop-up window 390 in the foregoing Figure 2K shown embodiment. The operation for the user to authorize the printer 200 to bind the specified cloud account in the binding pop-up window can be an operation on the confirmation control 393 in the above binding pop-up window 390. For specific content, reference can be made to the foregoing Figure 2K shown embodiment, which will not be elaborated here.

[0183] In a possible implementation, after the printing assistant receives the binding judgment result 1, it can display the binding pop-up window and directly execute the subsequent step S716.

[0184] S716. The printing assistant sends a binding request to the device management service. The device information of the printer 200 is carried in the binding request.

[0185] S717. The device management service sends a proxy binding request to the ecological access framework. Among them, the device information of the printer 200 and the specified cloud account are carried in the proxy binding request.

[0186] Since the cloud account currently logged in by the electronic device 101 in the device management service is the specified cloud account and the list of bound devices of the specified cloud account. Therefore, after the device management service receives the binding request sent by the printing assistant, it can obtain the device information of the printer 200 from the binding request and send a proxy binding request carrying the device information of the printer 200 and the specified cloud account to the ecological access framework.

[0187] Among them, the ecological access framework is used to communicate with the device cloud server.

[0188] S718. The ecological access framework sends a proxy registration request to the device cloud server. Among them, the device information of the printer 200, the specified cloud account and the registration authentication credential can be carried in the proxy registration request.

[0189] Among them, the ecological access framework can negotiate a challenge word with the device cloud server, and then the ecological access framework can obtain the fixed key of the preset printer 200. Then, the ecological access framework can calculate the registration authentication credential according to the device information of the printer 200, the challenge word and the fixed key.

[0190] S719. The device cloud server binds the device information of the printer 200 with the specified cloud account.

[0191] The device cloud server verifies the registration authentication credential, and after the verification of the registration authentication credential passes, it binds the device information of the printer 200 to the specified cloud account. Among them, the device cloud server can recalculate the registration authentication credential through the challenge word, the fixed key, and the device information of the printer 200. If the recalculated registration authentication credential is the same as the registration authentication credential carried in the proxy registration request, the verification of the registration authentication credential passes. After the verification of the registration authentication credential passes, the device cloud server can bind the device information of the printer 200 to the specified cloud account.

[0192] After the device cloud server binds the device information of the printer 200 to the specified cloud account, the printer 200 enters the trust ring corresponding to the specified cloud account. The device cloud server can store the device list corresponding to the specified cloud account, and the device list corresponding to the specified cloud account can record the device information of all devices logged in or bound to the specified cloud account. The device cloud server can manage and update the status information of all devices in the device list corresponding to the specified cloud account, and can synchronize the status information of all devices in the device list to the devices logged in to the specified cloud account. In this way, the devices logged in to this cloud account can view the status of the printer 200 or call the printer 200. Therefore, the device cloud server can synchronize the status information of the printer 200 to all devices (such as the electronic device 102) logged in to the specified cloud account. In this way, all devices logged in to the specified cloud account can call the printer 200 for printing.

[0193] S720. The device cloud server returns a binding success response to the ecological access framework. Among them, the binding success response is used to indicate that the printer 200 has successfully bound to the specified cloud account.

[0194] S721. The ecological access framework returns a binding success response to the device management service.

[0195] S722. The device management service adds the device information of the printer 200 to the list of bound devices of the specified cloud account.

[0196] Among them, since the device management service needs to regularly obtain the status information of each device logged in or bound to a specified cloud account from the device cloud server through the ecological access framework, and send the status information of each device to the control center, the control center can display the status information of each device logged in or bound to the specified cloud account in the intelligent interconnection interface. Therefore, after the device management service adds the device information of the printer 200 to the list of devices bound to the specified cloud account, it can obtain the status information of the printer 200 and send the status information of the printer 200 to the control center. The control center can display the status information of the printer 200 in the intelligent interconnection interface, and can also allow the user to select the printer 200 for printing in the intelligent interconnection interface. In this way, the user can call the printer 200 for printing at any time in the control center, instead of selecting the printer for printing in the intelligent space application every time.

[0197] S723. The device management service returns a binding success message to the print assistant. Among them, the binding success message is used to indicate that the printer 200 is successfully bound to the specified cloud account.

[0198] S724. The print assistant displays a binding success prompt.

[0199] Among them, the binding success prompt is used to prompt that the printer 200 has been successfully bound to the specified cloud account. Among them, the above step S724 is optional, and the print assistant may not display the binding success prompt.

[0200] In a possible implementation manner, the electronic device 101 can first configure the printer 200 to connect to the local area network where the electronic device 101 is located in the intelligent space application, and then use the printer 200 for printing. After the intelligent space application configures the printer 200 to successfully connect to the local area network where the electronic device 101 is located, it can trigger the electronic device 101 to request the cloud server 400 to bind the device information of the printer 200 and the specified cloud account through the print assistant. Among them, the process of the print assistant triggering the electronic device 101 to request the cloud server 400 to bind the device information of the printer 200 and the specified cloud account can refer to the above Figure 7 Steps S710 to S722 in the illustrated embodiment will not be described herein again.

[0201] In a possible implementation manner, the electronic device 101 can start the print assistant through the settings application and configure the printer 200 to connect to the local area network where the electronic device 101 is located in the print assistant. After the print assistant configures the printer 200 to connect to the local area network, it can request the cloud server 400 to bind the device information of the printer 200 and the specified cloud account. Among them, the process of the print assistant triggering the electronic device 101 to request the cloud server 400 to bind the device information of the printer 200 and the specified cloud account can refer to the above Figure 7Steps S710 to S722 in the illustrated embodiments will not be elaborated here.

[0202] Next, in combination with the above Figures 5A - 5B illustrated embodiments, a method flow for adding a printer to the control center will be specifically introduced.

[0203] Through the device management method provided in the embodiments of the present application, when the electronic device 101 detects that the user triggers the intelligent interconnection interface of the display control center and finds that the printer 200 is not bound to the specified cloud account, it can request the cloud server 400 to bind the device information of the printer 200 to the specified cloud account. Among them, the intelligent interconnection interface can be used to control devices within the trust ring corresponding to the specified cloud account to perform corresponding operations. In this way, the user can quickly call the printer 200 in the intelligent interconnection interface of the control center of the electronic device 101. Moreover, other devices logged in with the specified cloud account can receive the status information of the printer 200 and can also call the printer 200 for printing, which facilitates the user to use the same printer on different devices.

[0204] Figure 8 The flowchart shows a device management method provided in another embodiment of the present application.

[0205] As Figure 8 shown, this method can be applied to a communication system including an electronic device 101 and a cloud server 400. Among them, the electronic device 101 can include a control center, a device management service, a Nearby service, a printer discovery protocol, a print assistant, an ecological access framework (Magic Link), etc. The cloud server 400 can include a device cloud server.

[0206] Among them, this method can include the following steps:

[0207] S801. The control center detects an operation by the user to open the intelligent interconnection interface.

[0208] For example, the intelligent interconnection interface can be the intelligent interconnection interface 420 in the above Figure 5A illustrated embodiments. The user opening the intelligent interconnection interface can be the operation of the user clicking on the intelligent interconnection card 411 in the above Figure 2M illustrated embodiments. For specific details, reference can be made to the foregoing Figure 2M 、 Figure 5A illustrated embodiments and will not be elaborated here.

[0209] In the embodiments of the present application, the above intelligent interconnection interface can be referred to as the first interface.

[0210] S802. The control center registers device online / offline monitoring with the device management service.

[0211] The online and offline monitoring of this device is used to request the device management service to report the status information of the device logged in or bound to a specified cloud account to the control center after obtaining the status information of the device logged in or bound to the specified cloud account.

[0212] S803. The device management service sends a registration request to the Nearby service. Among them, the list of devices bound to the specified cloud account is carried in the registration request.

[0213] The device management service can manage and save the list of devices bound to the specified cloud account. The list of devices bound includes the device information of one or more devices logged in or bound to the specified cloud account. Therefore, the control center can display the status information of one or more devices logged in or bound to the specified cloud account on the intelligent interconnection interface.

[0214] Among them, the device information of the printer 200 includes the product identifier (proID) of the printer 200 (for example, "P1"), the device identifier, the device name (for example, "Printer P1"), etc. Among them, the device identifier can include any one of the unique device identifier (UDID), MAC address, etc.

[0215] S804. The Nearby service registers a device status callback with the printer discovery protocol.

[0216] Among them, after obtaining the list of devices bound, the Nearby service can match the discovery protocols corresponding to each device within the trust ring according to the device information in the list of devices bound, so as to search for each device logged in or bound to the specified cloud account through the discovery protocols corresponding to each device within the trust ring. Since the list of devices bound includes the device information of other printers, the Nearby service can search for the printer 200 using the printer discovery protocol. The Nearby service can register a device status callback with the printer discovery protocol, and this device status callback is used for the printer discovery protocol to send a device discovery notification to the Nearby service after discovering the printer.

[0217] S805. The printer discovery protocol discovers the printer 200.

[0218] Among them, the communication methods for the printer discovery protocol to discover the printer 200 include but are not limited to Bluetooth and Wi-Fi, etc.

[0219] S806. The printer discovery protocol calls back a device discovery notification to the Nearby service. Among them, the device discovery notification carries the device information of the printer 200.

[0220] The Nearby service determines whether the printer 200 is bound to a specified cloud account based on the list of bound devices and the device information of the printer 200.

[0221] If the device information of the printer 200 is in the list of bound devices, then the printer 200 is bound to the specified cloud account, and steps S808 to S810 are executed.

[0222] If the device information of the printer 200 is in the list of bound devices, but the printer 200 is not bound to the specified cloud account, then steps S811 to S830 are executed.

[0223] S808. The Nearby service sends the status information of the printer 200 to the device management service.

[0224] Among them, the status information includes the online status and the offline status. Among them, the online status can include the idle state, the printing state, and so on. Specifically, in this embodiment, the Nearby service sends the online status of the printer 200 to the device management service.

[0225] S809. The device management service sends the status information of the bound devices to the control center. Among them, the status information of the bound devices includes the status information of the printer 200.

[0226] Among them, the bound devices can include devices that are logged in or bound to the specified cloud account.

[0227] S810. The control center displays the status information of the bound devices.

[0228] For example, as described above Figure 2N As shown, after receiving the status information of the bound devices, the control center can display the device option 422 of the printer 200 in the intelligent interconnection interface 420. When the device option 422 of the printer 200 is displayed in the intelligent interconnection interface 420, it means that the status information of the printer 200 is the online status. When the device option 422 of the printer 200 is not displayed in the intelligent interconnection interface 420, it means that the status information of the printer 200 is the offline status. Optionally, the control center can also display the status information of the devices in the loop through other display styles, which is not limited here.

[0229] S811. The Nearby service sends a discovery notice of the device to be bound to the device management service. Among them, the discovery notice of the device to be bound includes the device information of the printer 200.

[0230] S812. The device management service sends a discovery notice of the device to be bound to the control center.

[0231] The control center displays a list of devices to be bound, where the list of devices to be bound includes the device name of the printer 200.

[0232] The control center detects an operation in which the user authorizes the printer 200 to bind to a specified cloud account.

[0233] For example, the list of devices to be bound can refer to the list of devices to be bound 550 in the foregoing Figure 5B shown embodiment. The operation in which the user authorizes the printer 200 to bind to a specified cloud account can be the operation of adding the control 552 to the list of devices to be bound 550. For specific content, reference can be made to the foregoing Figure 5B shown embodiment, which will not be elaborated here.

[0234] The control center sends a binding instruction to the print assistant.

[0235] Among them, the binding instruction carries the device information of the printer 200. This binding instruction is used to instruct the print assistant to trigger the binding of the printer 200 to the specified cloud account.

[0236] Among them, since different types of devices are bound to a specified cloud account in different ways, the control center can trigger the binding of different devices to the specified cloud account through the respective business applications corresponding to different types of devices. For example, the way of binding a speaker device to a specified cloud account is different from the way of binding a printer to a cloud account. The business application of the speaker device is the speaker assistant, and the business application of the printer is the print assistant. Therefore, the control center can trigger the binding of the printer 200 to the specified cloud account by means of the print assistant, and the control center can trigger the binding of the printer 200 to the specified cloud account by means of the speaker assistant.

[0237] The print assistant sends a binding request to the device management service. Among them, the binding request carries the device information of the printer 200.

[0238] The device management service sends a proxy binding request to the ecological access framework. Among them, the proxy binding request carries the device information of the printer 200 and the specified cloud account.

[0239] The ecological access framework sends a request for applying for registration information to the device cloud server.

[0240] Among them, the request for applying for registration information is used to request to apply to the device cloud server for the registration of the device.

[0241] The device cloud server returns an application response to the ecological access framework.

[0242] Among them, this application response is used to indicate that the device cloud server agrees to the registration of the device applied by the ecological access framework.

[0243] The ecological access framework sends a challenge word exchange request to the device cloud server.

[0244] The challenge word exchange request is used to obtain a challenge word (challengenumber). The challenge word is used to calculate a registration authentication credential together with the device information and the fixed key of the printer 200.

[0245] S821. The device cloud server returns a challenge word exchange response to the ecological access framework.

[0246] Among them, the challenge word is carried in the challenge word exchange response.

[0247] In this way, the ecological access framework and the device cloud server can save the same challenge word.

[0248] S822. The ecological access framework can obtain the fixed key of the preset printer 200.

[0249] S823. The ecological access framework calculates a registration authentication credential according to the device information, the challenge word and the fixed key of the printer 200.

[0250] S824. The ecological access framework sends a proxy registration request to the device cloud server. Among them, the proxy registration request can carry the device information of the printer 200, the specified cloud account and the registration authentication credential.

[0251] S825. The device cloud server verifies the registration authentication credential and binds the device information of the printer 200 to the specified cloud account.

[0252] Among them, the device cloud server can recalculate the registration authentication credential through the challenge word, the fixed key and the device information of the printer 200. If the recalculated registration authentication credential is the same as the registration authentication credential carried in the proxy registration request, the verification of the registration authentication credential passes. After the verification of the registration authentication credential passes, the device cloud server can bind the device information of the printer 200 to the specified cloud account.

[0253] Among them, a device list corresponding to the specified cloud account can be saved on the device cloud server. The device list corresponding to the specified cloud account can record the device information of all devices logged in or bound to the specified cloud account. The device cloud server can manage and update the status information of all devices in the device list corresponding to the specified cloud account, and can synchronize the status information of all devices in the device list to the devices logged in with the specified cloud account. In this way, the devices logged in with this cloud account can view the status of the printer 200 or call the printer 200.

[0254] After the device cloud account binds the device information of the printer 200 to a specified cloud account, it can return a binding success response to the ecological access framework. Among them, the binding success response is used to indicate that the printer 200 has successfully joined the trust ring corresponding to the specified cloud account.

[0255] S827. The ecological access framework can return a binding success response to the device management service.

[0256] S828. The device management service can return a binding success response to the print assistant.

[0257] Among them, after the print assistant obtains the returned binding success response, it can return a binding success response to the control center. The control center can display a binding success prompt after receiving the returned binding success response. Among them, the binding success prompt is used to prompt that the printer 200 is bound to the specified cloud account.

[0258] S829. The device management service can call the callbacks of each service to notify the control center of the status information of the bound device. Among them, the status information of the bound device includes the status information of the printer 200.

[0259] S830. The control center displays the status information of the bound device.

[0260] For example, as described above Figure 2N shown, after the control center receives the status information of the bound device, it can display the device option 422 of the printer 200 in the intelligent interconnection interface 420. When the device option 422 of the printer 200 is displayed in the intelligent interconnection interface 420, it means that the status information of the printer 200 is the online state. When the device option 422 of the printer 200 is not displayed in the intelligent interconnection interface 420, it means that the status information of the printer 200 is the offline state. Optionally, the control center can also display the status information of the bound device through other display styles, which is not limited here.

[0261] Next, in combination with the above Figures 2M - 2N shown embodiment, the process of displaying the printer online in the control center will be specifically introduced.

[0262] By displaying the device online in the control center provided in the embodiments of the present application, after the electronic device 101 requests the cloud server 400 to bind the device information of the printer 200 to a specified cloud account, when the user triggers the intelligent interconnection interface of the control center, the status information of the printer 200 can be quickly displayed in the intelligent interconnection interface of the control center, so that the user can use the printer 200 in the intelligent interconnection interface of the control center.

[0263] Figure 9The figure shows a schematic flow diagram of a method for displaying device online status in a control center provided in an embodiment of the present application.

[0264] As Figure 9 shown, this method can be applied to a communication system including an electronic device 101 and a printer 200. Among them, the electronic device 101 may include a control center, a shared service management framework, a print sharing service, a distributed print service, a printer 200, etc. Among them, the cloud server 400 has bound the device information of the printer 200 to a specified cloud account, and the electronic device 101 locally stores a list of devices bound to the specified cloud account, and the list of bound devices includes the device information of the printer 200.

[0265] The method may include the following steps:

[0266] S901. The control center detects an operation by the user to open the intelligent interconnection interface.

[0267] For example, the operation by the user to open the intelligent interconnection interface may be the operation on the intelligent interconnection control card 411 as shown in the above Figure 2M embodiment. For the specific content, reference may be made to the foregoing Figure 2N embodiment, which will not be elaborated here.
