[0040] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0041] Atomic services consist of one or more HAP packages, and one HAP package corresponds to one FA or one PA. Each FA or PA can run independently to complete specific functions; one or more functions (corresponding to FA or PA) complete one specific convenient service. Basic information of basic elements of atomic services: Each atomic service has an independent icon, name, description, and snapshot. Basic information will be displayed in the service center, system settings and other interfaces according to the scenario. Service card: In order to provide users with a convenient and intelligent service experience, each atomic service needs to develop at least one service card, and each application can optionally configure a service card. As a lightweight carrier of the service, the card needs to be easy to use, visible, intelligent, optional, and multi-terminal variable.

[0042] Multiple entrances: With the support of the Harmony0S Connect tag, atomic services can be discovered online and offline. Users can also discover and manage atomic services in the device's service center, desktop and other interfaces. Service flow: In Harmony0S, it generally refers to distributed operations involving multiple terminals. The flow capability breaks the boundaries of devices and multiple devices are linked, so that atomic services can be divided, combined and circulated, realizing distributed businesses such as cross-device editing of emails, multi-device collaborative fitness, and multi-screen games. Service sharing: Atomic services support sharing with other users through face-to-face or online channels. Device control: Harmony0S strives to create simple, easy-to-use, and natural and smooth device control functions for users. Users can easily connect and control HarmonyOS devices through their mobile phones, and "touch" the NFC tag of the Harmony0S device with their mobile phones. After identification, the mobile phone will run the corresponding atomic service.

[0043] The control method of atomic service flow described in the preferred embodiment of the present invention is as follows: Figure 1 As shown, the control method of the atomic service flow includes the following steps:

[0044] Step S10: The local device starts the flow management service according to the task flow instruction, pops up a device list through the flow management service, and starts the atomic service flow function when it is detected that the user selects the opposite device.

[0045] Specifically, Figure 2 As shown, on the current task page, click the transfer button to pull up the transfer management service, and the transfer management service pops up a device list. The user selects the target device (i.e., the opposite device, such as device 1, device 2, device 3, device 4, device 5) and then transfers the current task (i.e., the atomic service) (the purpose of the transfer is to open the atomic service on other devices and restore the status of the currently open page). That is, the local device receives the task transfer instruction clicked by the user on the current page, and pulls up the flow management service according to the task transfer instruction.

[0046] Or Figure 3 As shown, the local device receives the user's double-finger swipe-up operation instruction on the launcher page, and launches the flow management service according to the operation instruction.

[0047] Step S20: the local device obtains a logical view, divides multiple logical elements into modules according to the logical view to obtain logical modules, and transfers the atomic service flow to the opposite device according to the logical modules.

[0048] Specifically, Figure 4 As shown in the figure, it represents the 0-layer logic model (logical module, each subsystem in kaihongOS). The logical elements can be understood as the functional modules of each subsystem in kaihongOS in the current semantics. The logical elements in the system are divided into modules through the logical view, and the relationship between the logical elements is depicted, so that the logical modules have high cohesion and low coupling, and the logical modules provide service support for task flow.

[0049] Among them, high cohesion means that the elements within a module are related to each other and work together to complete a specific function. High cohesion means that the elements within a module are logically related and work together to complete a single task or goal. The more closely the elements within the module are related, the higher the cohesion of the module. Low coupling means that the dependencies between different modules should be as loose as possible. Low coupling means that there are fewer connections between modules, they are independent of each other, and changes in one module will not have too much impact on other modules. The lower the coupling between modules, the better the flexibility and maintainability of the system. Through the design principle of "high cohesion and low coupling", the software system can be made easier to understand, expand and maintain, reduce the risk of modification, and improve the stability and reliability of the system.

[0050] like Figure 4 As shown, the logic module includes an application layer and a system framework layer (i.e., framework layer, system service layer); the application layer includes task flow management services (i.e., mission: representing a task), flow management services (flow entry provided to third-party users) and an atomic service center (atomic service management center, flow initiation entry); the system framework layer includes distributed task scheduling (task management across devices), meta-capabilities (Ability operation management subsystem), Hap packages, application shared directories, ArkUI components (native UI framework on OpenHarmony), distributed file services (file management across devices, file synchronization between multiple devices), distributed security authentication and distributed soft buses.

[0051] Application layer:

[0052] (1) Develop a transfer management service application, which is responsible for popping up a window for users to select the target device for transfer and transferring through the continueMission interface.

[0053] (2) Atomic service center transformation: When the target device is not equipped with the service being transferred and cannot be downloaded through the cloud, the atomic service center (the application that manages the atomic service and the entry point for using the atomic service) actively distributes the local Hap package to the target device. The Hap package is a native application package that can be used for installation. The purpose of distributing the local Hap package is to install the locally installed application on the target device without the user's awareness, thus achieving installation-free operation.

[0054] System framework layer:

[0055] (1) The distributed scheduling component provides the entry continueMission for initiating migration.

[0056] (2) The Ability (Ability subsystem) runtime component (meta-capability) provides a migration callback interface onContinue. The migrated application can save state data on this interface and restore data on the callback interface onCreate / onNewWant of the target device.

[0057] (3) Data recovery mechanism. The ArkUI component provides a state management mechanism that can bind the data and page status information that need to be migrated to state variables (variables decorated by state decorators, and changes in the value of state variables will cause UI rendering updates) and restore them on the target device for migration.

[0058] (4) The shared directory uses the distributed file service HMDFS to share the local hap package between devices.

[0059] That is to say, when the service being circulated is not installed on the opposite device and cannot be downloaded through the cloud, the atomic service center actively distributes the local Hap package to the opposite device; wherein the atomic service center is used to manage the application of the atomic service and use the entrance of the atomic service; the local Hap package is a native application package for installation, and the atomic service center actively distributes the local Hap package to the opposite device for installing the locally installed application to the opposite device to achieve installation-free.

[0060] When data recovery is required, the ArkUI component is used to provide a state management mechanism, bind the data and page state information that need to be migrated to the state variables, and restore them on the migrated peer device.

[0061] After the opposite-end device restores the migration data through the transfer object application, the migration result is returned to the local-end device through the system framework layer. After receiving the migration result, the local-end device exits the transfer object application of the local-end device.

[0062] Furthermore, if Figure 5 As shown, it represents the 1-layer logic model, which is the expansion of the 0-layer logic model (1 layer is the expansion of each module of the 0-layer, describing in more detail how each module works together).

[0063] For example, Figure 5 Device A is the local device, and device B is the opposite device (target device). The following describes the service flow process between device A and device B.

[0064] Device A:

[0065] 1. Initiate a transfer (continueMission).

[0066] 2.dbms checks whether device B (target device) has the corresponding application installed.

[0067] Already installed: Skip steps 3 and 4 and continue with step 5.

[0068] Not installed: Continue with step 3.

[0069] 3. Device B is not installed, and the target application is an installation-free application and is launched in an installation-free manner.

[0070] 4. Check whether device B can be installed. (Check method: bms sends CONNECT_QUERY_RPCID to the atomic service center, and sends a message to the cloud via http for checking. If there is no cloud, it can be installed by default).

[0071] Yes: Continue the circulation.

[0072] No: End the transfer task and return an error message.

[0073] 5. Initiate a migration command to the transfer target application (the application to be transferred to the other end) of device A (the local device).

[0074] 6. The transfer object application of device A (local device) saves the migration data.

[0075] 7. Initiate a migration command to device B (the peer device).

[0076] Device B:

[0077] Check if it is installation-free migration and the transfer object application has not been installed yet, then perform installation-free first (installation-free method: send CONNECT_SILENT_INSTALL to the atomic service center).

[0078] Installation successful: Continue to step 9.

[0079] Installation failed: returns an error message.

[0080] 9. Send migration instructions to the transfer object application.

[0081] 10. The transfer object application restores the migration data and returns the migration result to device A through the framework layer.

[0082] Device A:

[0083] 11. After receiving the migration result, exit the transfer object application on the local device.

[0084] That is to say, to realize the service flow between two devices, device A (the original device on this end) initiates the flow and checks whether device B (the opposite device) has installed the corresponding application. If device B has not installed it and the flow target application is an installation-free application, it is pulled up in an installation-free manner to check whether the remote end can be installed. If device B has been installed, the flow continues. A migration instruction is initiated to the flow object application of device A. The flow object application of device A saves the migration data and initiates a migration instruction to device B. Device B checks whether it is an installation-free migration and the flow object application has not been installed, so it performs the installation-free first. If the installation is successful, a migration instruction is sent to the flow object application. The flow object application restores the migration data and returns the migration result to device A through the framework layer. After receiving the migration result, device A exits the flow object application of device A.

[0085] The development view mainly describes the code repository location of related subsystems from a development perspective, as well as the dependencies of compilation and build, compilation tool chain, and compilation environment information.

[0086] Develop circulation management services and transform the atomic service center. Make the following transformations to the atomic service center application to support the circulation of installation-free applications when the other end is not installed.

[0087] The atomic service center receives the CONNECT_QUERY_RPCID request:

[0088] Call the shareHap interface to put the corresponding Hap package into the shared directory and return true.

[0089] The atomic service center receives the CONNECT_SILENT_INSTALL request:

[0090] Follow the original logic, download and install from the cloud.

[0091] When the cloud download fails, install Hap in the shared directory.

[0092] Delete the Hap package in the shared directory.

[0093] The present invention aims to solve the problem in the prior art that when the target device needs to use the application function of the original device, it needs to re-download and install the application or transfer the installation package from the original device to achieve this, resulting in slow application transmission and installation, inconvenient use, and inability to quickly realize the rapid flow of tasks. The present invention can quickly realize the rapid flow and operation of tasks (atomic services) between different devices without the need for application installation, making it more convenient for service providers and users to obtain and use services.

[0094] Furthermore, if Figure 6 As shown, based on the above-mentioned control method for atomic service flow, the present invention also provides a control system for atomic service flow, wherein the control system for atomic service flow includes:

[0095] The transfer start module 51 is used for the local device to pull up the transfer management service according to the task transfer instruction, pop up the device list through the transfer management service, and start the atomic service transfer function when it is detected that the user selects the opposite device;

[0096] The service flow module 52 is used for the local device to obtain a logical view, divide multiple logical elements into modules according to the logical view to obtain logical modules, and transfer the atomic service flow to the opposite device according to the logical modules.
