Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a multi-device collaboration method and an electronic device. Background Art

[0002] With the increase in personal distributed devices, the demand for cross-screen collaboration of multiple devices is becoming more and more vigorous. The multi-device collaboration function is a cross-screen management function that provides applications, content, data, and hardware. For example, if a user has a smartphone, a tablet computer, and a laptop computer, multiple devices can transmit data based on near-field communication technology. When the user uses one of the devices, the device can receive data sent by other devices that are connected to the device, so that the user can control or operate other devices through the device being used. In addition, the multi-device collaboration function can also realize resource sharing between multiple devices, such as quick transmission of documents, images and other multimedia resources between multiple devices.

[0003] However, near-field communication technologies such as Bluetooth and wireless fidelity (Wi-Fi) only support communication within the near-field connection range. If the distance between devices increases, the communication link between devices may be disconnected, causing the collaboration to be interrupted. Therefore, there are limitations to the current multi-device collaboration based on near-field communication technology. Summary of the invention

[0004] The present application provides a multi-device collaboration method and an electronic device for improving the flexibility and reliability of multi-device collaboration.

[0005] In the first aspect, the present application provides a multi-device collaboration method, which can be performed by an electronic device. In the method, in response to a first operation triggered by a user, at least one candidate device is searched through a near-field device discovery function and a far-field device discovery function; in response to a second operation triggered by a user, a target device is determined from the at least one candidate device; a far-field network channel is established with the target device, and the far-field network channel is used to transmit control information and / or data between the electronic device and the target device through a server; a near-field data transmission channel is established based on the far-field network channel; after the near-field data transmission channel is successfully established, device collaboration is performed with the target device through the near-field data transmission channel.

[0006] In the above method, when the user triggers the first operation to start multi-device collaboration, the electronic device can search for at least one candidate device through near-field device discovery and far-field device discovery, and establish a far-field network channel with the target device selected by the user. The electronic device can establish a near-field data transmission channel with the target device based on the far-field network channel, thereby flexibly establishing a near-field data transmission channel between the electronic device and the target device, thereby improving the reliability of multi-device collaboration.

[0007] In one possible design, before establishing a near-field data transmission channel based on the far-field network channel, the method includes: establishing a near-field negotiation channel with the target device, the near-field negotiation channel being used to transmit control information related to the near-field network; performing signaling negotiation corresponding to the near-field data transmission channel with the target device based on the near-field network negotiation channel, and the signaling negotiation fails.

[0008] Through this design, after the electronic device establishes a near-field negotiation channel with the target device, it can first perform signaling negotiation for the near-field data transmission channel based on the near-field negotiation channel. When the signaling negotiation fails, the electronic device can perform signaling negotiation for the near-field data transmission channel based on the far-field network channel, thereby providing multiple ways to establish near-field data transmission channels and improving the success rate of multi-device collaboration.

[0009] In one possible design, the method further includes: when the near-field data transmission channel fails to be established, performing device collaboration with the target device through the far-field network channel.

[0010] Through this design, when the near-field data transmission channel fails to be established, the electronic device can reuse the far-field network channel to collaborate with the target device, provide data transmission channels for collaboration among multiple devices, and improve the reliability of multi-device collaboration.

[0011] In one possible design, the device collaboration with the target device through the near-field data transmission channel includes: using a first resolution and a first frame rate transmission method to send the device collaboration-related data to the target device through the near-field data transmission channel; the device collaboration with the target device through the far-field network channel includes: using a second resolution and a second frame rate transmission method to send the device collaboration-related data to the target device through the far-field network channel; the second resolution is smaller than the first resolution, and the second frame rate is smaller than the first frame rate.

[0012] Through this design, when an electronic device transmits data related to device collaboration with a target device, if the data is transmitted through a near-field data transmission channel, a higher resolution and frame rate can be used; if the data is transmitted through a far-field network channel, a lower resolution and frame rate can be used, thereby ensuring the stability of data transmission in multi-device collaboration.

[0013] In one possible design, establishing a near-field data transmission channel based on the far-field network channel includes: performing signaling negotiation corresponding to the near-field data transmission channel on the far-field network channel; after the signaling negotiation is completed, establishing the near-field data transmission channel.

[0014] In one possible design, the signaling negotiation corresponding to the near-field data transmission channel on the far-field network channel includes: receiving the address and port number sent by the target device through the far-field network channel; and establishing the near-field data transmission channel according to the address and port number sent by the target device.

[0015] In a second aspect, the present application provides an electronic device, the electronic device comprising a plurality of functional modules; the plurality of functional modules interact with each other to implement the method performed by the electronic device in the first aspect and its respective embodiments. The plurality of functional modules may be implemented based on software, hardware, or a combination of software and hardware, and the plurality of functional modules may be arbitrarily combined or divided based on specific implementation.

[0016] In a third aspect, the present application provides an electronic device comprising at least one processor and at least one memory, wherein the at least one memory stores computer program instructions, and when the electronic device is running, the at least one processor executes the method executed by the electronic device in the above-mentioned first aspect and each embodiment thereof.

[0017] In a fourth aspect, the present application further provides a computer program product comprising instructions, which, when executed on a computer, enables the computer to execute the method executed by the electronic device in any of the above aspects and each embodiment thereof.

[0018] In a fifth aspect, the present application also provides a computer-readable storage medium, in which a computer program is stored. When the computer program is executed by a computer, the computer executes the method executed by the electronic device in any of the above aspects and its various embodiments.

[0019] In a sixth aspect, the present application also provides a chip, which is used to read a computer program stored in a memory and execute the method executed by the electronic device in any of the above aspects and its various embodiments.

[0020] In a seventh aspect, the present application further provides a chip system, which includes a processor for supporting a computer device to implement the method executed by an electronic device in any of the above aspects and its various embodiments. In a possible design, the chip system also includes a memory, which is used to store the necessary programs and data of the computer device.

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. Among them, in the description of the embodiments of the present application, the terms "first" and "second" are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0029] It should be understood that in the embodiments of the present application, "at least one" refers to one or more, and "plurality" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b or c can represent: a, b, c, a and b, a and c, b and c, or a, b and c, where a, b, c can be single or multiple.

[0030] With the increase in personal distributed devices, the demand for cross-screen collaboration of multiple devices is becoming more and more vigorous. The multi-device collaboration function is a cross-screen management function that provides applications, content, data, and hardware. For example, if a user has a smartphone, a tablet computer, and a laptop computer, multiple devices can transmit data based on near-field communication technology. When the user uses one of the devices, the device can receive data sent by other devices that are connected to the device, so that the user can control or operate other devices through the device being used. In addition, the multi-device collaboration function can also realize resource sharing between multiple devices, such as quick transmission of documents, images and other multimedia resources between multiple devices.

[0031] As mentioned above, the current multi-device collaboration functions are mostly implemented based on near-field communication technology, such as Bluetooth, Wi-Fi, and other communication technologies that support near-field connection range. However, the location of devices commonly used by general users may change at any time. If the distance between devices becomes longer and exceeds the maximum distance supported by near-field communication, the communication link between the devices will be disconnected, causing collaboration interruption. It can be seen that the current multi-device collaboration based on near-field communication technology has limitations.

[0032] Based on the above problems, an embodiment of the present application provides a multi-device collaboration method, which can be executed by an electronic device. Figure 1 This is a schematic diagram of a scenario applicable to the embodiment of the present application. Figure 1 , the scenario may include at least two electronic devices and at least one server, Figure 1 Two electronic devices (electronic device 1 and electronic device 2) and a server are used as an example. At least one server is used to provide cloud services for establishing a far-field network channel for at least two electronic devices. Figure 1In the example of multi-device collaboration between electronic device 1 and electronic device 2, in the multi-device collaboration method provided in the embodiment of the present application, electronic device 1 can start far-field device discovery and near-field device discovery. Electronic device 1 determines at least one candidate device that can establish a communication connection through far-field device discovery and near-field device discovery. The user selects a device from at least one candidate device for multi-device collaboration, such as the user selects electronic device 2 from at least one candidate device. Electronic device 1 establishes a near-field network negotiation channel with electronic device 2 based on near-field communication technology, and electronic device 1 establishes a far-field network channel with electronic device 2 based on far-field communication technology. Electronic device 1 can establish a near-field data transmission channel based on the near-field network negotiation channel or the far-field network channel. If the near-field data transmission channel is successfully established, electronic device 1 and electronic device 2 can transmit data through the near-field data transmission channel. If the near-field data transmission channel fails to be established, electronic device 1 can reuse the far-field network channel as a data transmission channel, and transmit data with electronic device 2 through the data transmission channel. Through this scheme, when multi-device collaboration is performed between electronic devices, the scope of multi-device collaboration between electronic devices can be expanded through far-field communication technology, without the need to perform multi-device collaboration within the scope supported by near-field communication. In addition, electronic devices can flexibly establish data transmission channels based on near-field communication technology or far-field communication technology to improve the efficiency of multi-device collaboration.

Figure 3 As shown, the software structure of the electronic device can be a layered architecture, for example, the software can be divided into several layers, each layer has a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the operating system is divided into four layers, from top to bottom, namely, the application layer, the application framework layer (framework, FWK), the runtime (runtime) and the system library, and the kernel layer.

[0059] The notification manager enables applications to display notification information in the status bar. It can be used to convey notification-type messages and can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also be a notification that appears in the system top status bar in the form of a chart or scroll bar text, such as notifications of applications running in the background, or a notification that appears on the screen in the form of a dialog window. For example, a text message is displayed in the status bar, a prompt sound is emitted, an electronic device vibrates, an indicator light flashes, etc.

[0060] The runtime includes the core library and the virtual machine. The runtime is responsible for the scheduling and management of the operating system.

[0061] The core library consists of two parts: one is the function that the Java language needs to call, and the other is the core library of the operating system. The application layer and the application framework layer run in the virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform object life cycle management, stack management, thread management, security and exception management, and garbage collection.

[0062] The system library may include multiple functional modules, such as surface manager, media libraries, 3D graphics processing library (such as OpenGL ES), 2D graphics engine (such as SGL), image processing library, etc.

[0063] The surface manager is used to manage the display subsystem and provide the fusion of 2D and 3D layers for multiple applications.

[0064] The media library supports playback and recording of a variety of commonly used audio and video formats, as well as static image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0065] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0066] A 2D graphics engine is a drawing engine for 2D drawings.

[0067] The kernel layer is the layer between hardware and software. The kernel layer contains at least display driver, camera driver, audio driver, and sensor driver.

[0068] The hardware layer can include various types of sensors, such as accelerometers, gyroscopes, touch sensors, etc.

[0069] It should be noted that Figure 2 and Figure 3 The structure shown is only an example of the electronic device provided by the embodiment of the present application, and cannot be used to limit the electronic device provided by the embodiment of the present application.

The server may include a device cloud, a far-field communication cloud, and a PUSH cloud. Among them, the device discovery module in the electronic device is used to discover connectable near-field devices and / or far-field devices, and deduplicate the discovered near-field devices and far-field devices, and retain at least one non-repetitive connectable candidate device. The connection channel management module is used to establish and manage near-field network negotiation channels, far-field network channels, and near-field data transmission channels. The collaboration module is used to adaptively adjust parameters such as collaborative frame rate and resolution according to the type and bandwidth of the data transmission channel. The device cloud in the server is used to register and query far-field devices, the far-field communication cloud is used to establish a far-field network channel and transmit data based on the far-field network channel, and the PUSH cloud is used to pull up applications for far-field devices.

[0072] It should be noted that the embodiments of the present application do not limit the specific implementation method of the server function. For example, the server may be a distributed computing cluster, which may include at least one computing device. Different computing devices are used to implement different functions of the server in the above embodiments. For example, multiple computing devices can be used to implement the functions of the device cloud, far-field communication cloud and PUSH cloud respectively.

[0073] refer to Figure 4 , the near field communication technology in the embodiment of the present application includes but is not limited to Bluetooth and Wi-Fi. The following takes Bluetooth as an example to illustrate the establishment method of the near field network channel. The user can operate the electronic device 1 to turn on the Bluetooth function of the electronic device 1. When the user triggers the electronic device 1 to turn on multi-device collaboration, the electronic device 1 can turn on the device discovery based on Bluetooth to find the device that can establish a Bluetooth connection with the electronic device 1 within the Bluetooth support range. The electronic device 1 can display at least one candidate device found, and the user can select a device from at least one candidate device to establish a Bluetooth connection with the device. For example, the user can select electronic device 2 from at least one candidate device. Electronic device 1 can establish a near field Bluetooth negotiation channel with electronic device 2. The near field Bluetooth negotiation channel is a control channel for transmitting control information, such as specifically for electronic device 1 and electronic device 2 to perform signaling negotiation. Electronic device 1 and electronic device 2 can perform signaling negotiation on the near field Bluetooth negotiation channel. After the signaling negotiation is completed, electronic device 1 can establish a near field data transmission channel based on the near field Bluetooth negotiation channel. The near field data transmission channel is a data channel for transmitting data between electronic device 1 and electronic device 2.

[0074] The far-field communication technology in the embodiment of the present application can be a communication method established between electronic devices through a server, refer to Figure 4, the user can operate the electronic device 1 to turn on the Wi-Fi switch of the electronic device 1.

The electronic device 1 can display at least one candidate device found, and the user can select a device from at least one candidate device to establish a far-field network channel with the device. The far-field network channel between electronic devices in the embodiment of the present application can be used as a control channel or as a data channel, that is, the far-field network channel can be used to transmit control information or data. In addition, in the embodiment of the present application, the electronic device can also perform signaling negotiation in the far-field network channel to establish a near-field data transmission channel. For example, the user selects electronic device 2 from at least one candidate device. When the terminal communication service of the far-field device is not turned on, the electronic device 1 pulls up the communication service of the electronic device 2 through the PUSH cloud, and then establishes a far-field network channel with the electronic device 2 through the far-field communication cloud, and performs signaling negotiation on the far-field network channel. After the signaling negotiation is completed, the electronic device 1 can establish a near-field data transmission channel based on the far-field network channel. If the signaling negotiation fails, the establishment of the near-field data transmission channel fails, and the electronic device 1 can use the far-field network channel as a data transmission channel.

[0075] The following is a further introduction to the multi-device collaboration method provided in the embodiment of the present application:

[0076] Figure 5 This is a flowchart of a method for multi-device collaboration provided by an embodiment of the present application, which can be executed by an electronic device. Figure 5 , the method comprises the following steps:

[0077] S501: In response to a first operation triggered by a user, the electronic device starts a multi-device collaboration function.

[0078] Optionally, the first operation may be an operation triggered by a user to enable the multi-device collaboration function, such as the first operation may be a click operation triggered by a user on a multi-device collaboration control.

[0079] In an embodiment of the present application, electronic devices can perform multi-device collaboration based on near-field communication technology and / or far-field communication, and electronic devices can pre-configure the electronic devices to use near-field communication technology and far-field communication for multi-device collaboration by default; the multi-device collaboration function setting of the electronic device may include near-field communication technology such as Bluetooth, Wi-Fi and other options, and may also include far-field communication options. Users can also customize the communication technology used for multi-device collaboration in the setting interface of the multi-device collaboration function, and the embodiment of the present application does not limit this.

[0080] Optionally, multi-device collaboration may include functions such as multi-screen collaboration between electronic devices, document transmission between electronic devices, and multimedia resource transmission between electronic devices.

[0081] S502: The electronic device starts near-field device discovery, and the electronic device starts far-field device discovery, and the electronic device searches for at least one candidate device.

[0082] In the embodiment of the present application, after the electronic device turns on the multi-device collaboration function, the near-field device discovery and far-field device discovery can be turned on to find at least one candidate device that can establish a connection with the electronic device. For example, after the electronic device turns on the near-field Bluetooth device discovery, it can search for Bluetooth broadcast signals sent by other electronic devices, and after receiving the Bluetooth broadcast signal, the electronic device that sends the Bluetooth broadcast signal is used as a candidate device.

[0083] In some embodiments, when an electronic device finds the same other electronic device through near-field device discovery and far-field device discovery, the other electronic device is also only used as a candidate device. When the electronic device displays at least one found candidate device on the interface, an identifier of the candidate device can be displayed.

[0084] S503: In response to a second operation of the user, the electronic device determines a target device from at least one candidate device.

[0085] Optionally, the second operation may be an operation of selecting a target device triggered by a user. For example, the electronic device may display the identifier of at least one candidate device found on an interface, and the user may click the identifier of the target device to select the target device.

[0086] S504: The electronic device establishes a negotiation channel with the target device according to the communication mode of the target device.

[0087] In some embodiments, when the electronic device finds the target device through near-field device discovery, the electronic device can establish a near-field negotiation channel with the target device. For example, when the electronic device finds the target device through Bluetooth device discovery, the electronic device can establish a Bluetooth negotiation channel with the target device.

[0088] In some other embodiments, when the electronic device finds the target device through far-field device discovery, the electronic device can establish a far-field network channel with the target device, and the far-field network channel can be used as a negotiation channel.

[0089] In some other embodiments, if the electronic device finds the target device through both near-field device discovery and far-field device discovery, the electronic device can establish a near-field network negotiation channel and a far-field network channel with the target device.

[0090] S505: The electronic device establishes a data transmission channel based on the established negotiation channel.

[0091] According to the above introduction to the near-field communication technology and far-field communication technology involved in the embodiments of the present application, when the electronic device establishes a near-field data transmission channel, it is necessary to perform signaling negotiation on the negotiation channel, and establish the near-field data transmission channel after the signaling negotiation is completed. Therefore, according to the different types of negotiated communications established by the electronic device in S504 of the embodiment of the present application, the methods for establishing a data transmission channel between the electronic device and the target device are also different. The following introduces different methods for establishing a data transmission channel between the electronic device and the target device in several cases:

[0092] Method 1:

[0093] When there is a near-field network negotiation channel and no far-field network channel, the electronic device performs signaling negotiation based on the near-field network negotiation channel. After the signaling negotiation is completed, the electronic device can establish a near-field data transmission channel. If the signaling negotiation fails in the near-field network negotiation channel, the electronic device fails to cooperate with the target device.

[0094] Method 2:

[0095] When there is a far-field network channel and no near-field network negotiation channel, the electronic device can first perform signaling negotiation corresponding to the near-field data transmission channel based on the far-field network channel. After the signaling negotiation is completed, the electronic device can establish the near-field data transmission channel. If the electronic device fails to perform signaling negotiation based on the far-field network channel, the electronic device can use the far-field network channel as a data transmission channel.

[0096] Method 3:

[0097] When there is a far-field network channel and a near-field network negotiation channel, the electronic device can perform signaling negotiation based on the near-field network negotiation channel. After the signaling negotiation is completed, a near-field data transmission channel is established. At this time, data transmission can be performed between the electronic device and the target device through the near-field data transmission channel and / or the far-field network channel. If the electronic device fails to perform signaling negotiation on the near-field network negotiation channel, the electronic device can perform signaling negotiation corresponding to the near-field data transmission channel again on the far-field network channel. If the signaling negotiation is completed, a near-field data transmission channel is established. If the signaling negotiation fails, the electronic device can use the far-field network channel as a data transmission channel.

[0098] In some embodiments, the near-field data transmission channel may be a Wi-Fi peer-to-peer (P2P) channel. When the electronic device performs signaling negotiation of the near-field data transmission channel with the target device, the electronic device may receive the Internet Protocol (IP) address of the target device and the port number corresponding to the Wi-Fi P2P channel sent by the target device through the near-field network negotiation channel. The electronic device may establish a Wi-Fi P2P channel with the target device based on the IP address of the target device and the port number corresponding to the Wi-Fi P2P channel.

[0099] S506: The electronic device performs data transmission with the target device through the established data transmission channel.

[0100] In an embodiment of the present application, when the electronic device sends data to the target device through an established data transmission channel, the data transmission mode can be determined according to the type of data transmission channel established between the electronic device and the target device. Optionally, if there is a near-field data transmission channel between the electronic device and the target device, the electronic device can use a data transmission mode with a first resolution and a first frame rate for data transmission. If there is no near-field data transmission channel between the electronic device and the target device, and there is a far-field network channel, the electronic device can use a data transmission mode with a second resolution and a second frame rate for data transmission, wherein the second resolution is less than the first resolution, and the second frame rate is less than the first frame rate. If there is a near-field data transmission channel and a far-field network channel between the electronic device and the target device, the electronic device can use a data transmission mode with a first resolution and a first frame rate to transmit data on the near-field data transmission channel.

[0101] It should be noted that the first resolution, the first frame rate, the second resolution and the second frame rate in the above embodiments may be preset values, or may be user-defined values, and the embodiments of the present application are not limited to this.

[0102] In some embodiments, the time required for an electronic device to establish a near-field data transmission channel and a far-field network channel is different. The electronic device can perform data transmission on the data transmission channel that has been established first. If other data transmission channels are successfully established later, the electronic device can adjust the data transmission method. For example, after the electronic device successfully establishes the far-field network channel, it can use the second resolution and the second frame rate data transmission method to perform data transmission on the far-field network channel; after the electronic device completes the signaling negotiation on the near-field Bluetooth negotiation channel, it establishes the near-field data transmission channel, and the electronic device can adjust to use the first resolution and the first frame rate data transmission method to perform data transmission on the near-field data transmission channel.

[0103] It can be understood that the near-field communication technology and far-field communication technology in the above embodiments are only examples and not limitations. The multi-device collaboration method provided in the embodiments of the present application can also be applied to new communication technologies that emerge in future communication developments, and the embodiments of the present application do not limit this.

[0104] The following is an example to introduce the multi-device collaboration method provided in the embodiment of the present application. Figure 6 A schematic diagram of a multi-device collaboration method provided in an embodiment of the present application, referring to Figure 6 , the method comprises the following steps:

[0105] S601: The electronic device detects a first operation triggered by a user for starting a multi-device collaboration function.

[0106] For example, the first operation is a click operation performed by a user on a multi-device collaborative control.

[0107] S602: The electronic device starts far-field device discovery.

[0108] S603: The electronic device searches for and reports at least one candidate far-field device.

[0109] In an optional implementation, far-field device discovery is to search for a device that can establish a far-field communication connection with the electronic device based on far-field communication technology. The far-field communication technology may be, for example, a communication technology for electronic devices to exchange data through a server. The electronic device may search for at least one candidate far-field device based on far-field device discovery, and the electronic device may establish a far-field network channel with any candidate far-field device.

[0110] S604: The electronic device initiates near-field device discovery.

[0111] S605: The electronic device searches for and reports at least one candidate near-field device.

[0112] In an optional implementation, near-field device discovery is to search for devices within the support range of the near-field communication technology that can establish a near-field communication connection with the electronic device based on the near-field communication technology. For example, the near-field communication technology may be Bluetooth technology. After the electronic device turns on the Bluetooth function, it can search for other devices within the Bluetooth support range that turn on the Bluetooth function, and it can also be searched by other devices within the Bluetooth support range that turn on the Bluetooth function. The electronic device can search for at least one candidate near-field device based on near-field device discovery, and the electronic device can establish a near-field network negotiation channel with any candidate near-field device.

[0113] It should be noted that S602-S603 and S604-S605 can be executed synchronously.

[0114] S606: The electronic device performs device fusion on the found at least one candidate far-field device and the found at least one candidate near-field device to obtain at least one candidate device.

[0115] In some implementations, at least one candidate far-field device and at least one candidate near-field device found by the electronic device may have overlapping devices. For example, if the electronic device finds device A through near-field device discovery, and the electronic device also finds device A through far-field device discovery, then when the electronic device displays at least one candidate device that can perform device collaboration to the user, it only needs to display one device A, without repeatedly displaying two devices A. Therefore, the electronic device can perform device fusion on the at least one candidate far-field device and the at least one candidate near-field device found to obtain at least one candidate device.

[0116] S607: In response to the second operation of the user selecting a target device from at least one candidate device, the electronic device starts device collaboration with the target device.

[0117] The electronic device may display at least one candidate device found on a display screen, and the user may select a target device from the at least one candidate device, thereby triggering the second operation. After the user selects the target device, the electronic device may start to establish a communication channel with the target device to achieve device collaboration.

[0118] S608: The electronic device determines that at least one candidate near-field device reported during near-field device discovery includes the target device.

[0119] S609: The electronic device establishes a Bluetooth negotiation channel with the target device.

[0120] In one implementation, when the electronic device determines that the target device is a candidate near-field device, it may establish a Bluetooth negotiation channel with the target device, and the Bluetooth negotiation channel may be used to transmit control information.

[0121] S610: The electronic device determines that at least one candidate far-field device reported during far-field device discovery includes a target device.

[0122] S611: The electronic device establishes a far-field P2P channel with the target device.

[0123] In one implementation, when the electronic device determines that the target device is a candidate far-field device, it may establish a far-field network channel with the target device, such as a far-field P2P channel. The far-field P2P channel may be used to transmit control information and / or data.

[0124] S612: The electronic device determines whether the Bluetooth negotiation channel is available. If yes, proceed to S614; otherwise, proceed to S613.

[0125] Optionally, the near-field P2P channel is a near-field data transmission channel, for example, the near-field P2P channel may be a Wi-Fi P2P channel.

[0126] S613: The electronic device determines whether the far-field P2P channel is available. If yes, proceed to S614; otherwise, it is determined that the multi-device collaboration fails.

[0127] S614: The electronic device performs signaling negotiation corresponding to the near-field P2P channel.

[0128] Based on the above steps, the electronic device can first determine whether the Bluetooth negotiation channel is available. If available, the electronic device can perform signaling negotiation of the near-field data transmission channel based on the Bluetooth negotiation channel, such as the electronic device can perform signaling negotiation corresponding to the near-field P2P channel based on the Bluetooth negotiation channel. If the Bluetooth negotiation channel is not available, the electronic device can determine whether the far-field P2P channel is available. If available, the electronic device can perform signaling negotiation corresponding to the near-field P2P channel based on the far-field P2P channel. In other words, the embodiments of the present application provide multiple ways to establish near-field P2P channels to reduce the risk of collaboration failure.

[0129] S615: The electronic device determines whether the near-field P2P channel is successfully established. If so, it proceeds to S616; otherwise, it proceeds to S617.

[0130] S616: The electronic device transmits the device collaboration-related data to the target device in a near-field P2P channel in a high-resolution, high-frame-rate transmission manner.

[0131] S617: The electronic device determines whether the far-field P2P channel is available. If so, proceed to S618. Otherwise, it is determined that the multi-device collaboration fails.

[0132] S618: The electronic device transmits the device collaboration-related data to the target device in a far-field P2P channel in a low-resolution, low-frame-rate transmission manner.

[0133] It should be noted that the high resolution and high frame rate in the above S616 and the low resolution and low frame rate in S618 are only relative concepts in the embodiment of the present application. In implementation, the high resolution and high frame rate may be a resolution and frame rate with a higher preset value, and the low resolution and low frame rate may be a resolution and frame rate with a lower preset value.

[0134] Based on the above steps, electronic devices can set different resolutions and frame rates for data transmission according to the type of data transmission channel to ensure the stability of device collaboration.

[0135] Based on the same concept, an embodiment of the present application also provides a multi-device collaboration method, which can be executed by an electronic device. Figure 7A flowchart of a multi-device collaboration method provided in an embodiment of the present application. Figure 7 , the method comprises the following steps:

[0136] S701: In response to a first operation triggered by a user, the electronic device searches for at least one candidate device through a near-field device discovery function and a far-field device discovery function.

[0137] Optionally, the first operation may be an operation triggered by a user to start a multi-device collaboration function, such as the first operation being a click operation performed by a user on a multi-device collaboration control.

[0138] S702: In response to a second operation triggered by a user, the electronic device determines a target device from at least one candidate device.

[0139] Optionally, the second operation may be an operation of the user selecting a target device from at least one candidate device.

[0140] S703: The electronic device establishes a far-field network channel with the target device.

[0141] The far-field network channel is used to transmit control information and / or data between the electronic device and the target device through the server.

[0142] S704: The electronic device establishes a near-field data transmission channel based on the far-field network channel.

[0143] S705: After the near-field data transmission channel is successfully established, the electronic device performs device collaboration with the target device through the near-field data transmission channel.

[0144] pass Figure 7 The multi-device collaboration method provided by the illustrated embodiment, when the user triggers the first operation to start multi-device collaboration, the electronic device can search for at least one candidate device through near-field device discovery and far-field device discovery, and establish a far-field network channel with the target device selected by the user. The electronic device can establish a near-field data transmission channel with the target device based on the far-field network channel, thereby flexibly establishing a near-field data transmission channel between the electronic device and the target device, thereby improving the reliability of multi-device collaboration.

[0145] In an optional implementation, before establishing a near-field data transmission channel based on the far-field network channel in S704, the electronic device may also establish a near-field negotiation channel with the target device, and the near-field negotiation channel is used to transmit control information related to the near-field network; the electronic device performs signaling negotiation corresponding to the near-field data transmission channel with the target device based on the near-field network negotiation channel, and the signaling negotiation fails.

[0146] That is to say, in the embodiment of the present application, the electronic device first performs signaling negotiation corresponding to the near-field data transmission channel based on the near-field negotiation channel. After the signaling negotiation fails, the electronic device can then perform signaling negotiation corresponding to the near-field data transmission channel based on the far-field network channel, thereby providing multiple ways to establish near-field data transmission channels and improving the success rate of multi-device collaboration.

[0147] In an optional implementation, when the electronic device fails to establish a near-field data transmission channel in S705, the electronic device can perform device collaboration with the target device through the far-field network channel, thereby providing a data transmission channel for collaboration of multiple devices and improving the reliability of multi-device collaboration. During implementation, a near-field data transmission channel is established based on the far-field network channel, including: performing signaling negotiation corresponding to the near-field data transmission channel on the far-field network channel; after the signaling negotiation is completed, establishing the near-field data transmission channel. Optionally, signaling negotiation corresponding to the near-field data transmission channel is performed on the far-field network channel, including: receiving the address and port number sent by the target device through the far-field network channel; and establishing a near-field data transmission channel according to the address and port number sent by the target device.

[0148] In an optional implementation, in S705, device collaboration is performed with the target device via a near-field data transmission channel, including: using a transmission method with a first resolution and a first frame rate to send data related to device collaboration to the target device via the near-field data transmission channel; device collaboration is performed with the target device via a far-field network channel, including: using a transmission method with a second resolution and a second frame rate to send data related to device collaboration to the target device via the far-field network channel; the second resolution is smaller than the first resolution, and the second frame rate is smaller than the first frame rate.
