[0071] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0072] In this application, the terms "first," "second," etc., are used to distinguish identical or similar items with essentially the same function. It should be understood that there is no logical or temporal dependency between "first," "second," and "nth," nor are there any restrictions on quantity or execution order.

[0073] In this application, the term "at least one" means one or more, and "multiple" means two or more, for example, multiple first positions means two or more first positions.

[0074] Before introducing the embodiments of this application, it is necessary to introduce some basic concepts in the field of cloud technology:

[0075] Cloud technology refers to a hosting technology that unifies hardware, software, and network resources within a wide area network (WAN) or local area network (LAN) to achieve data computation, storage, processing, and sharing. It encompasses network technologies, information technologies, integration technologies, management platform technologies, and application technologies based on cloud computing business models. These technologies can form resource pools, allowing for on-demand, flexible, and convenient use. Cloud computing technology will become a crucial support in the cloud technology field. Backend services of technical network systems require substantial computing and storage resources, such as those for video websites, image websites, and various portal websites. With the rapid development and application of the internet industry, every item may have its own identification mark in the future, requiring transmission to backend systems for logical processing. Data at different levels will be processed separately, and various industry data will require robust system support, all of which can be achieved through cloud computing.

[0076] Cloud computing refers to a delivery and usage model for IT (Internet Technology) infrastructure, enabling users to access necessary resources on demand and in a scalable manner via a network. In other words, cloud computing is a computing model that distributes computing tasks across a resource pool composed of numerous computers, allowing various application systems to obtain computing power, storage space, and information services as needed. The network providing these resources is called the "cloud." From the user's perspective, resources in the "cloud" are infinitely scalable, readily available, and can be used on demand, scaled as needed, and paid for based on usage. As a provider of basic cloud computing capabilities, a cloud resource pool (Infrastructure as a Service, IaaS, or cloud platform for short) is established, deploying various types of virtual resources within the pool for external customers to choose from. The cloud resource pool primarily includes: computing devices (virtualized machines containing operating systems), storage devices, and network devices. Based on logical function, a PaaS (Platform as a Service) layer can be deployed on top of the IaaS layer, and a SaaS (Software as a Service) layer can be deployed on top of the PaaS layer. Alternatively, the SaaS layer can be deployed directly on top of the IaaS layer. The PaaS layer is the platform for running software, such as databases and web (web page) containers. The SaaS layer consists of various business software, such as web portals and bulk SMS senders. Generally speaking, the SaaS and PaaS layers are upper layers compared to the IaaS layer.

[0077] In a broad sense, cloud computing refers to a service delivery and usage model, meaning obtaining required services through a network in an on-demand and easily scalable manner. These services can be IT and software-related, internet-related, or other services. Cloud computing is a product of the development and integration of traditional computer and network technologies such as grid computing, distributed computing, parallel computing, utility computing, network storage technologies, virtualization, and load balancing.

[0078] With the development of the internet, real-time data streams, and the diversification of connected devices, as well as the demands for search services, social networks, mobile commerce, and open collaboration, cloud computing has rapidly developed. Unlike previous parallel distributed computing, cloud computing will fundamentally revolutionize the entire internet model and enterprise management model.

[0079] Cloud Apps: Applications that interact between a terminal and a service (cloud). Terminal operations are synchronized with the cloud, and the local space occupied is also backed up and retained through the cloud. Cloud Apps are a subset of the cloud computing concept, representing the application layer of cloud computing technology. The biggest difference between cloud applications and cloud computing is that cloud computing exists as a macro-level technological development concept, while cloud applications are products that directly address real-world customer problems. The working principle of cloud applications is to transform the traditional "local installation, local computation" of software into an "on-demand" service. They connect to and control remote server clusters via the internet or local area network to complete business logic or computational tasks. The main carrier of cloud applications is internet technology, presented as thin clients or smart clients. Their interfaces are essentially an integration of technologies such as HTML5 (HyperText Markup Language 5), JavaScript (JS), and Flash (an interactive vector graphics and web animation standard). Cloud applications can not only help users reduce IT costs, but also greatly improve work efficiency. When local applications are overloaded or have high requirements for device configuration, cloud application technology enables terminals to have better performance.

[0080] Inter-Process Communication (IPC), also known as cross-process communication, refers to technologies that enable communication between multiple applications. IPC refers to techniques or methods for transferring data or signals between at least two processes or threads. A process is the smallest unit of resource allocation in a computer system (while a thread is the smallest unit of scheduling, and threads share process resources). Each process has its own independent set of system resources and is isolated from others. Inter-process communication exists to enable different processes to access each other's resources and coordinate their work. IPC technologies include message passing, synchronization, shared memory, and remote procedure calls.

[0081] This application relates to an IPC communication mechanism in the context of cloud applications. When a certain service of a cloud application needs to call another cloud application, this application can realize IPC communication between two different cloud applications, making cloud application technology applicable to business scenarios involving interaction across multiple applications. The details are as follows.

[0082] Figure 1 This is a schematic diagram illustrating the implementation environment of a data transmission method provided in an embodiment of this application. See also... Figure 1 The implementation environment includes a terminal 101 and a server 102, both of which are computer devices.

[0083] Terminal 101 is used to run a first application and a second application. The first application and the second application are different cloud applications. The first application provides a target function option, which allows the user to access the services provided by the second application in the first application by triggering the target function option.

[0084] In one example, the first application is a shopping app, the second application is a data transfer app, and the service is a data transfer service. The user initiates the data transfer service after completing a purchase in the shopping app. Optionally, the data transfer service includes card payment based on bank card passwords, fingerprint payment based on fingerprint sensing, and facial recognition payment based on facial images. For example, the shopping app could be a third-party merchant ERP (Enterprise Resource Planning), the data transfer app could be a payment app or a social app with integrated payment functionality, and the data transfer service could be a payment service, a money transfer service, etc.

[0085] In another example, the first application is a short video application, music application, or other application that supports content consumption, and the second application is a value transfer application. This service is a virtual resource transfer service. Users can view content of interest in the content-consumption-supporting application and initiate a virtual resource transfer service to reward the creator of that content. It should be noted that the virtual resources for rewarding include, but are not limited to, encrypted assets, game equipment, game materials, game pets, game currency, icons, badges, memberships, titles, value-added services, points, gold coins, gold beans, gift certificates, exchange coupons, coupons (including discount coupons and vouchers), greeting cards, etc. This disclosure does not limit the type of virtual resources.

[0086] Terminal 101 and server 102 can be connected directly or indirectly via wired or wireless communication, and this application does not impose any restrictions on this.

[0087] Server 102 is used to provide backend services for the first and second applications. Server 102 is commonly referred to as "the cloud". Optionally, server 102 is an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms, or a virtualization center.

[0088] Optionally, terminal 101 refers to one of a plurality of terminals, the device type of which includes at least one of the following: smartphone, tablet computer, e-book reader, MP3 (Moving Picture Experts Group Audio Layer III) player, MP4 (Moving Picture Experts Group Audio Layer IV) player, laptop computer, desktop computer, smart speaker, or smartwatch. For example, terminal 101 is a laptop computer, or other portable electronic device.

[0089] Those skilled in the art will understand that the number of terminals 101 described above can be more or less. For example, there may be only one terminal 101, or there may be dozens or hundreds of terminals 101, or even more. This application does not limit the number or type of terminals 101 in the embodiments.

[0090] Figure 2 This is a flowchart illustrating a data transmission method provided in an embodiment of this application. See also... Figure 2 This embodiment applies to a computer device, and takes server 102 in the above implementation environment as an example for illustration. This embodiment includes the following steps:

[0091] 201. The server obtains the target operation data of the terminal, which is used to trigger access to the services provided by the second application in the first application.

[0092] Optionally, the target operation data is the operation data generated and sent by the terminal after collecting the user's triggered operation.

[0093] In some embodiments, the first application is a shopping application and the second application is a data transfer application, thus the service is a data transfer service. In other embodiments described later, the data transfer service will be used as an example for detailed explanation, and will not be repeated here. In other embodiments, the first application is a short video application, music application, or other application that supports content consumption, and the second application is a data transfer application; therefore, the service is a virtual resource transfer service. This application does not specifically limit the type of the first application or the type of the second application.

[0094] In some embodiments, the target operation data is used to represent a trigger operation for a target function option in the first application, and the target function option is used to access the service provided by the second application. Optionally, the trigger operation includes, but is not limited to, click operations, long press operations, double-click operations, voice commands, gesture commands, facial expression recognition commands, etc. This application embodiment does not specifically limit the type of trigger operation. Optionally, the target function option is a visual UI (User Interface) control in the first application. For example, the UI control is a virtual button displayed on the current page of the first application. The virtual button can be a circular button, a rectangular button, or an irregularly shaped button. Alternatively, the UI control is a preset menu option in the menu bar of the first application. This application embodiment does not specifically limit the display method of the UI control.

[0095] In some embodiments, if the triggering operation is identified based on a user's touch operation on the terminal screen, the target operation data may include the event type of the triggering operation, the screen location information of the target function option, and the page information to which the target function option belongs in the first application. For example, the event type is a click, the screen location information is the terminal screen coordinates (X, Y2), and the page information is the current page identifier (Page ID) where the click event occurs.

[0096] In other embodiments, if the triggering operation is identified based on a voice command input by the user in a first application, the target operation data may include the event type of the triggering operation, the voice signal collected by the first application, and the page information when the user inputs the voice command. For example, the event type is a voice command, the voice signal is the sound signal of the user saying "Buy a chicken cutlet rice", and the page information is the merchant details page currently being viewed by the user.

[0097] In some embodiments, the terminal, based on the user's triggering operation of a target function option in a first application, collects the target operation data of the triggering operation, encapsulates the target operation data into an instruction structure to obtain a target instruction, and sends the target instruction to the server. The server receives the target instruction sent by the terminal, parses the target instruction, and obtains the target operation data.

[0098] In the above process, by encapsulating the target operation data into an instruction structure, the raw operation data of various machine models can be uniformly encapsulated into an instruction structure with a consistent format. This not only saves communication overhead between the terminal and the server, but also facilitates the server's parsing and processing of the instruction structure, thereby improving the server's data processing efficiency.

[0099] 202. Based on the target operation data, the server controls the terminal to display the second application.

[0100] In some embodiments, the server includes a global state controller that provides global state control services among multiple cloud applications. For example, the global state controller records the running status information of multiple cloud applications and schedules how to switch between them. In one example, the global state controller records the current running interface of a cloud application and can control whether the current cloud application needs to be displayed in the foreground or suspended in the background.

[0101] Optionally, the global state controller may be one or more node devices in the server cluster that perform global state control, or the global state controller may be a global state control module (e.g., a function, a process, a control system, etc.) integrated in a node device in the server.

[0102] In some embodiments, the server obtains status control information based on the target operation data. The status control information is used to instruct the terminal to switch the first application to the background and the second application to the foreground. The server also sends the status control information to the terminal based on the global status controller.

[0103] In some embodiments, the server obtains the event type that triggers the operation, the screen location information of the target function option, and the page information to which the target function option belongs in the first application, all included in the target operation data. Using the triple formed by the event type, screen location information, and page information as an index, the server queries the database for the corresponding index content. If the index content matches any processing logic, the server executes that processing logic, generates the state control information, and calls the global state controller to send the state control information to the terminal's local state control center. In this database, different event types, screen location information, and page information carried in the target operation data are stored in correspondence with the processing logic corresponding to that target operation data; that is, a mapping relationship between the target operation data and the corresponding processing logic is constructed.

[0104] In the above process, the global state controller can provide a solution for how different cloud applications in the cloud scheduling terminal can switch displays at the appropriate time, thereby solving the communication problem between multiple cloud applications in the cloud application system.

[0105] In some embodiments, the server generates status control information based on the target operation data, encapsulates the status control information into a control command using a data transmission protocol, and sends the control command to the terminal, causing the terminal to respond to the control command and switch the second application to the foreground for display. Optionally, if the second application has not yet started when the control command is received, the terminal starts the second application first and then displays it in the foreground. Optionally, if the second application has already started but is suspended in the background when the control command is received, the terminal directly switches the second application to the foreground for display.

[0106] In some embodiments, the server may also generate two status control messages based on the target operation data. Specifically, the status control messages include a first control message and a second control message. The first control message indicates that the first application should be switched to the background, and the second control message indicates that the second application should be switched to the foreground. The server may encapsulate the first and second control messages into different control commands based on data transmission protocols, or it may encapsulate the first and second control messages in the same control command and send one or more encapsulated control commands to the terminal. This causes the terminal to respond to the one or more control commands by switching the first application to the background and suspending it, and switching the second application to the foreground for display.

[0107] In the above process, by generating a single state control information, the communication overhead between the terminal and the server can be saved. By generating multiple state control information, the server's control accuracy over the terminal display interface can be improved. This application embodiment does not specifically limit the number of state control information generated.

[0108] 203. The server sends the streaming media data of the second application to the terminal. The streaming media data is the data generated by the service triggered by the target operation data.

[0109] In some embodiments, the server invokes the second application to execute the service triggered by the target operation data, records the screen display data of the second application, and generates the streaming media data based on the screen display data.

[0110] In the above process, the server calls the second application to execute the business based on the state control information, and the second application records and collects the streaming media data during its own application runtime, and pushes the recorded streaming media data to the terminal. This can transfer the local computing load of the terminal to the server with more powerful computing capabilities, and the terminal only needs to "use it as needed" to realize cross-application business, which greatly improves the communication efficiency between cloud applications.

[0111] It should be noted that the first application and the second application can be cross-platform, enabling the terminal to access the services provided in the second application in the cloud based on its own platform's first application. It has high cross-platform compatibility, ease of use and lightweight nature. It can not only solve the problem of excessive local application load or excessive device configuration requirements, but also solve the problem of cross-process communication between multiple cloud applications.

[0112] All of the above-mentioned optional technical solutions can be combined in any way to form optional embodiments of this disclosure, and will not be described in detail here.

[0113] The method provided in this application embodiment can remotely control the terminal to switch the other application to the foreground display by obtaining the operation data of the terminal triggering access to another application in one application, and push the streaming media data of the other application to the terminal. It can solve the cross-process communication problem between multiple cloud applications in the context of cloud applications, and can bring users a smooth user experience by macro-scheduling the switching display status between different applications.

[0114] Figure 3 This is an interactive flowchart of a data transmission method provided in an embodiment of this application. See also... Figure 3 This embodiment is applied to the interaction process between terminal 101 and server 102 in the above implementation environment, which will be described in detail below:

[0115] 301. In response to the user's triggering operation on the target function option in the first application, the terminal encapsulates the target operation data into an instruction structure to obtain the target instruction, and sends the target instruction carrying the target operation data to the server.

[0116] The target operation data is the operation data generated and sent by the terminal after collecting the user's triggered operation. The target function option is used to access the services provided by the second application. The target instruction is an instruction structure encapsulated by the target operation data.

[0117] Optionally, the triggering operation includes, but is not limited to: click operation, long press operation, double click operation, voice command, gesture command, facial expression recognition command, etc. This application embodiment does not specifically limit the type of triggering operation.

[0118] Optionally, the target function option is a visual UI control in the first application. For example, the UI control is a virtual button displayed on the current page of the first application. The virtual button can be a circular button, a rectangular button, or an irregularly shaped button. Alternatively, the UI control is a preset menu option in the menu bar of the first application. This application embodiment does not specifically limit the display method of the UI control.

[0119] In some embodiments, the target operation data includes the event type that triggered the operation, the screen location information of the target function option, and the page information to which the target function option belongs in the first application. For example, the event type is a click, the screen location information is the terminal screen coordinates (X, Y2), and the page information is the current page ID where the click event occurs.

[0120] In some embodiments, after the terminal encapsulates the target operation data into an instruction structure, it can further encapsulate the instruction structure based on a data transmission protocol to ensure that the target instruction can be transmitted smoothly in the network. Optionally, before encapsulation, the instruction structure can be compressed based on a compression algorithm to save communication overhead between the terminal and the server. Optionally, before encapsulation, the instruction structure can be encrypted based on an encryption algorithm to improve the transmission security of the target instruction. This application does not limit whether the target instruction needs to be compressed or encrypted.

[0121] In this embodiment, taking the triggering operation based on the target function option as an example, a possible implementation method for the terminal to send target operation data to the server is provided. Optionally, the user can also directly input a voice command in the first application to trigger the terminal to send target operation data to the server, or the user can input a gesture command in the first application to trigger the terminal to send target operation data to the server, or the user can turn on the camera component in the first application, capture their own facial expression image, perform expression recognition on the facial expression image, obtain a facial expression recognition command, and trigger the terminal to send target operation data to the server. The terminal can support any one or at least a combination of the above methods to trigger the terminal to send target operation data to the server, so as to improve the operability of the terminal and facilitate the user to choose the triggering method most suitable for them. This embodiment does not specifically limit the triggering method.

[0122] In other embodiments, if the triggering operation is identified based on a voice command input by the user in a first application, the target operation data may include the event type of the triggering operation, the voice signal collected by the first application, and the page information when the user inputs the voice command. For example, the event type is a voice command, the voice signal is the sound signal of the user saying "Buy a chicken cutlet rice", and the page information is the merchant details page currently being viewed by the user.

[0123] In other embodiments, if the triggering operation is identified based on a gesture command input by the user in a first application, the target operation data may include the event type of the triggering operation, the gesture signal collected by the first application, the finger command corresponding to the gesture signal, and the page information when the user inputs the gesture command. For example, the event type is a gesture command, the gesture signal is a "S" shaped gesture made by the user pressing and dragging on any page of the first application, the gesture command is to trigger the repurchase of the same product as the most recent historical order, and the page information is the page currently viewed by the user.

[0124] In other embodiments, if the triggering operation is based on a facial expression image captured by the user using the camera component in the first application, the target operation data may include the event type of the triggering operation, the facial expression image captured by the first application, the expression command identified based on the facial expression image, and the page information when the user inputs the expression command. For example, the event type is an expression command, the facial expression image is a face image captured by the user using the camera component in the first application, the expression command is to trigger the purchase of the latest item added to the shopping cart, and the page information is the page currently viewed by the user.

[0125] In the above process, it is shown that under different triggering methods, the target operation data can contain different information, and is not limited to the three types of event type, screen position information and page information. It can also include voice commands, gesture commands, facial expression commands, etc. The embodiments of this application do not specifically limit the composition of the target operation data.

[0126] In some embodiments, in addition to encapsulating the target operation data into target instructions and sending them to the server, the terminal can also directly send the collected raw target operation data to the server, which can simplify the processing flow on the terminal side.

[0127] 302. The server receives the target instruction from the terminal, parses the target instruction, and obtains the target operation data.

[0128] The target operation data is used to trigger access to services provided by the second application within the first application.

[0129] In some embodiments, after receiving a target instruction sent by a terminal, the server can parse the target instruction to obtain the target operation data. Optionally, the server parses the target instruction based on an instruction stream service module; in one example, the instruction stream service module is the AIDL interface of launchFacePayApp.

[0130] In some embodiments, if the terminal encrypts the target instruction using an encryption algorithm, the server needs to use a decryption algorithm corresponding to the encryption algorithm to decrypt the target instruction. If the terminal compresses the target instruction using a compression algorithm, the server needs to use a decompression algorithm corresponding to the compression algorithm to decompress the target instruction. This application does not limit this aspect.

[0131] In the above process, a possible implementation method for the server to obtain the target operation data of the terminal is provided. Taking the terminal encapsulating the target operation data into an instruction structure and then transmitting it as an example, by encapsulating the target operation data into an instruction structure, the original operation data of various different models can be uniformly encapsulated into an instruction structure with a consistent format. This not only saves the communication overhead between the terminal and the server, but also facilitates the server's parsing and processing of the instruction structure, thereby improving the server's data processing efficiency.

[0132] In some embodiments, the terminal may not encapsulate the target operation data into an instruction structure, but instead send the target operation data directly. This simplifies the processing flow on the terminal side and also simplifies the parsing flow on the server side.

[0133] 303. Based on the target operation data, the server obtains status control information, which is used to instruct the terminal to switch the first application to the background and the second application to the foreground.

[0134] In some embodiments, the server obtains the event type that triggers the operation, the screen location information of the target function option, and the page information to which the target function option belongs in the first application, all included in the target operation data. Using the triple formed by the event type, screen location information, and page information as an index, the server queries the database for the corresponding index content. If the index content matches any processing logic, the server executes that processing logic, generates the state control information, and calls the global state controller to send the state control information to the terminal's local state control center. In this database, different event types, screen location information, and page information carried in the target operation data are stored in correspondence with the processing logic corresponding to that target operation data; that is, a mapping relationship between the target operation data and the corresponding processing logic is constructed.

[0135] In some embodiments, the server generates a status control message based on the target operation data. This status control message is used to indicate only that the second application be switched to the foreground. Alternatively, the server may generate two status control messages based on the target operation data. That is, the status control message includes a first control message and a second control message. The first control message is used to indicate that the first application be switched to the background, and the second control message is used to indicate that the second application be switched to the foreground.

[0136] In the above process, by generating a single state control information, the communication overhead between the terminal and the server can be saved. By generating multiple state control information, the server's control accuracy over the terminal display interface can be improved. This application embodiment does not specifically limit the number of state control information generated.

[0137] 304. The server sends status control information to the terminal based on the global status controller.

[0138] In some embodiments, the server includes a global state controller that provides global state control services among multiple cloud applications. For example, the global state controller records the running status information of multiple cloud applications and schedules how to switch between them. In one example, the global state controller records the current running interface of a cloud application and can control whether the current cloud application needs to be displayed in the foreground or suspended in the background.

[0139] Optionally, the global state controller may be one or more node devices in the server cluster that perform global state control, or the global state controller may be a global state control module (e.g., a function, a process, a control system, etc.) integrated in a node device in the server.

[0140] In the above process, the global state controller can provide a solution for how different cloud applications in the cloud scheduling terminal can switch displays at the appropriate time, thereby solving the communication problem between multiple cloud applications in the cloud application system.

[0141] In some embodiments, if the server generates a status control information based on the target operation data, it encapsulates the status control information into a control command using a data transmission protocol, and then sends the control command to the terminal.

[0142] In some embodiments, if the server generates two status control information (i.e., the first control information and the second control information) based on the target operation data, the server can encapsulate the first control information and the second control information into different control instructions based on the data transmission protocol, or encapsulate the first control information and the second control information in the same control instruction and send one or more encapsulated control instructions to the terminal.

[0143] In steps 303-304 above, a possible implementation method is provided in which the server controls the terminal to display the second application based on the target operation data. The global state controller in the cloud sends state control information to the local state control center of the terminal, which can make the data transmission between the terminal and the server more standardized. It can also establish a redundant sending mechanism, that is, send multiple copies of the same state control information at one time to avoid missing state control information due to network fluctuations.

[0144] In some embodiments, the server may send state control information directly to the terminal without going through a global state controller, so that the terminal switches the second application to the foreground. In this way, the server does not need to be configured with a global state controller, and the terminal does not need to be configured with a state control center locally, which simplifies the data transmission process.

[0145] 305. The terminal displays the second application based on the status control information returned by the server.

[0146] In some embodiments, if the server sends a control command encapsulated in status control information to the terminal, the terminal responds to the control command by switching the second application to the foreground for display. Optionally, if the second application has not yet started when the control command is received, the terminal starts the second application first and then displays it in the foreground. Optionally, if the second application has already started but is suspended in the background when the control command is received, the terminal directly switches the second application to the foreground for display.

[0147] In some embodiments, if the server sends one or more control instructions encapsulated by both the first control information and the second control information to the terminal, the terminal responds to the one or more control instructions by switching the first application to the background and suspending it, and switching the second application to the foreground for display. Optionally, if the second application has not yet started when the control instruction is received, the terminal starts the second application first and then displays it in the foreground. Optionally, if the second application has already started but is suspended in the background when the control instruction is received, the terminal directly switches the second application to the foreground for display.

[0148] 306. The server calls the second application to execute the business triggered by the target operation data and records the screen display data of the second application.

[0149] During the above process, based on the status control information, the server determines that the terminal needs to switch the second application to the foreground display. Then, it calls the second application to execute the business triggered by the target operation data. For example, when the business is a value transfer business, the value transfer interface is displayed in the second application, and the screen display data of the value transfer interface is recorded in real time.

[0150] 307. Based on the screen display data, the server generates streaming media data for the second application, which is the data generated by the service triggered by the target operation data.

[0151] In some embodiments, the server records the screen display data of the second application frame by frame, which can form a screen data stream and acquire the screen data stream as the streaming media data.

[0152] In steps 306-307 above, the server calls the second application to execute the business based on the status control information, and the second application records and collects the streaming media data during its own application runtime, and pushes the recorded streaming media data to the terminal. This can transfer the local computing load of the terminal to the server with more powerful computing capabilities, and the terminal only needs to "use it as needed" to realize cross-application business, which greatly improves the communication efficiency between cloud applications.

[0153] 308. The server sends the streaming media data of the second application to the terminal.

[0154] Optionally, the server encapsulates the streaming media data based on a streaming media transmission protocol and sends the encapsulated streaming media data to the terminal. Optionally, before encapsulation, the server can use a compression algorithm to compress the streaming media data to save communication overhead between the terminal and the server. Alternatively, before encapsulation, the server can also use an encryption algorithm to encrypt the streaming media data to improve the transmission security of the streaming media data. This application embodiment does not limit whether the streaming media data needs to be compressed or encrypted.

[0155] In some embodiments, the first application and the second application can be cross-platform, enabling the terminal to access services provided in the second application in the cloud based on its own platform's first application. This has high cross-platform compatibility, ease of use, and lightweight nature, which can not only solve the problem of excessive local application load or high device configuration requirements, but also solve the problem of cross-process communication between multiple cloud applications.

[0156] 309. The terminal responds to receiving the streaming media data from the second application and plays the streaming media data in the second application.

[0157] In some embodiments, the terminal plays the streaming media data in a second application based on playback controls. As the streaming media data plays, it collects the target operation data triggered by the user in real time and re-executes step 301 to trigger the user to complete the required access service in the second application. For example, the terminal displays a value transfer interface in the second application, which includes transaction information and verification options. In response to the user's triggering operation on the verification option, the terminal obtains the target operation data for the triggered operation and sends it to the server. This allows the server to initiate the verification process for the current value transfer based on the target operation data, such as using card verification or facial recognition.

[0158] All of the above-mentioned optional technical solutions can be combined in any way to form optional embodiments of this disclosure, and will not be described in detail here.

[0159] The method provided in this application embodiment can remotely control the terminal to switch the other application to the foreground display by obtaining the operation data of the terminal triggering access to another application in one application, and push the streaming media data of the other application to the terminal. It can solve the cross-process communication problem between multiple cloud applications in the context of cloud applications, and can bring users a smooth user experience by macro-scheduling the switching display status between different applications.

[0160] Figure 4 This is an interactive flowchart of a data transmission method provided in an embodiment of this application. See also... Figure 4 This embodiment is applied to the interaction process between terminal 101 and server 102 in the above-described implementation environment. Based on the previous embodiment, it is illustrated by taking a shopping application as the first application and a data transfer application as the second application. In this case, the service provided by the second application is a data transfer service. This embodiment includes the following steps:

[0161] 401. In response to the user's triggering operation on the value transfer option in the shopping application, the terminal encapsulates the target operation data into an instruction structure, obtains the target instruction, and sends the target instruction carrying the target operation data to the server.

[0162] This data transfer option is used to access the data transfer services provided by the data transfer application.

[0163] In the above process, the terminal responds to the user's trigger operation on the value transfer option in the shopping application and sends the target operation data to the server. Step 401 is similar to step 301 above, and will not be described in detail here.

[0164] 402. The server receives the target instruction from the terminal, parses the target instruction, and obtains the target operation data.

[0165] In the above process, the server obtains the target operation data of the terminal. This target operation data is used to trigger the access to the value transfer service provided by the value transfer application in the shopping application. Step 402 is similar to step 302 above, and will not be described in detail here.

[0166] 403. Based on the target operation data, the server obtains status control information, which is used to instruct the terminal to switch the shopping application to the background and switch the value transfer application to the foreground.

[0167] Step 403 above is similar to step 303 above, and will not be described in detail here.

[0168] 404. The server sends status control information to the terminal based on the global status controller.

[0169] In the above process, the server controls the terminal to display the value transfer application based on the target operation data. Step 404 is similar to step 304 above, and will not be described in detail here.

[0170] 405. Based on the status control information returned by the server, the terminal displays the value and transfers it to the application.

[0171] Step 405 is similar to step 305 above, and will not be described in detail here.

[0172] 406. The server calls the value transfer application to execute the value transfer business triggered by the target operation data, and records the screen display data of the value transfer application.

[0173] Step 406 above is similar to step 306 above, and will not be described in detail here.

[0174] 407. Based on the screen display data, the server generates streaming media data for the value transfer application. This streaming media data is the data generated by the value transfer service triggered by the target operation data.

[0175] Step 407 is similar to step 307 above, and will not be described in detail here.

[0176] 408. The server sends the streaming media data of the value transfer application to the terminal.

[0177] Step 408 is similar to step 308 above, and will not be described in detail here.

[0178] 409. The terminal responds to receiving the streaming media data from the data transfer application and plays the streaming media data in the data transfer application.

[0179] Step 409 is similar to step 309 above, and will not be described in detail here.

[0180] The method provided in this application embodiment can remotely control the terminal to switch the value transfer application to the foreground display by obtaining the operation data of the terminal triggering access to the value transfer application in the shopping application, and push the streaming media data of the value transfer application to the terminal. It can solve the cross-process communication problem between multiple cloud applications in the context of cloud applications, and can bring users a smooth user experience by macro-scheduling the switching display status between different applications.

[0181] Figure 5 This is a schematic flowchart illustrating a data transmission method provided in an embodiment of this application. Please refer to it. Figure 5 In a cloud application system, there are two parts: cloud 501 and device 502. Cloud 501 is the server, and device 502 is the terminal.

[0182] The cloud-based 501 module provides backend services, deploys one or more cloud-based physical devices, and runs multiple cloud applications on these devices. The cloud-based 501 module involves three types of service modules: 1) An instruction stream service module, used to parse instruction data uploaded from the front end (i.e., device 502) and convert it into corresponding communication instructions. For example, the instruction stream service module calls the Android AIDL interface; 2) A global state controller, used to record the running status information of cloud applications and to schedule switching services between multiple cloud applications. For example, it records the running interface of the current cloud application and controls whether the terminal switches the current cloud application to the foreground or suspends it in the background; 3) A streaming media service module, used to provide streaming media services for multiple cloud applications. This refers to the service where multiple cloud applications record their own screens, collect the streaming media data of the currently running cloud application, and push the streaming media data to the cloud application running on device 502.

[0183] Multiple cloud applications run on device 502. The core of each cloud application includes a backend screen recording module that captures streaming media data during the current cloud application's runtime. Device 502 can collect raw instruction information (i.e., target operation data) from user operations and convert it into a raw instruction structure, which is then passed to the corresponding backend instruction stream service module. Device 502 also includes a state control center, which receives state control information from the global state controller in cloud 501 and executes corresponding processing logic based on this information.

[0184] Within the framework of the aforementioned cloud application system Figure 6This is a schematic flowchart illustrating a data transmission method provided in this application embodiment, as shown in Figure 600. The example given is a user calling a facial recognition payment service from a payment application via a merchant ERP application on a terminal. The merchant ERP application is hereinafter referred to as the merchant APP, which is an example of the first application involved in the above embodiments. The payment application is hereinafter referred to as the facial recognition APP, which is an example of the second application involved in the above embodiments. The service provided by the second application accessed from the first application is the facial recognition payment service.

[0185] Step 1: After the device starts up, the cloud sends the current interface status information (Page1D1) and related streaming media data of the merchant's APP to the device, and the merchant's APP on the device plays the streaming media data.

[0186] Step 2: After shopping on the merchant's app on the device, the user clicks the face recognition payment button (i.e., the target function option).

[0187] Step 3: The merchant APP on the device side collects the current user operation data (Page1D1, x, y2, click), encapsulates it into a raw instruction structure, and passes it to the instruction stream service module of the merchant APP on the cloud.

[0188] Where Page1D1 refers to the page information of the target operation data, (x, y2) refers to the screen position information of the target operation data, and click refers to the event type of the target operation data.

[0189] Step 4: The instruction stream service module of the cloud merchant APP parses the original instruction and obtains the corresponding action.

[0190] For example, the instruction stream service module is the AIDL interface for launchFacePayApp.

[0191] Step 5: After receiving the AIDL interface from launchFacePayApp, the cloud-based face recognition app starts and notifies the global state controller to switch the device-side merchant app to the background while simultaneously switching the face recognition app to the foreground. The cloud-based merchant app stops pushing streaming media services, while the cloud-based face recognition app begins pushing streaming media services.

[0192] Step 6: The user makes a face payment using the facial recognition app on the device.

[0193] In this embodiment of the application, by storing the mapping table of operations and instructions in the cloud and related scheduling services, the device only needs to collect the current user's raw operation data (i.e., raw operation data) to solve the problem of cross-process communication between multiple apps in cloud application scenarios.
