[0078] The technical solutions in the embodiments of the present application will be clearly and elaborately described below in conjunction with the accompanying drawings. Among them, in the description of the embodiments of the present application, unless otherwise specified, " / " means "or". For example, A / B may represent A or B; "and / or" in the text is only an association relationship describing associated objects, indicating that there can be three relationships. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone.

[0079] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as implying or suggesting relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0080] Referring to "embodiments" in the present application means that the specific features, structures, or characteristics described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described in the present application may be combined with other embodiments.

[0081] The term "user interface (UI)" in the following embodiments of the present application is a media interface for interaction and information exchange between an application program or an operating system and a user, which realizes the conversion between the internal form of information and the form acceptable to the user. The user interface is source code written in specific computer languages such as Java and Extensible Markup Language (XML). The interface source code is parsed and rendered on an electronic device and finally presented as content recognizable by the user. The common manifestation form of the user interface is a graphical user interface (GUI), which refers to a user interface related to computer operations presented in a graphical manner. It can be visible interface elements such as text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, and Widgets displayed on the display screen of an electronic device.

[0082] The present application relates to the following terms:

[0083] Shared service

[0084] Shared service refers to the ability provided by an electronic device to share resources such as data, screen, and other software and hardware capabilities. Enabling the shared service involves two devices, provided that a connection is established. After the connection is established, the two devices can enable the shared service based on the connection.

[0085] Shared services can include the following categories: keyboard and mouse sharing, screen sharing, remote control, and cross-device calls, etc. The following elaborates on these shared services.

[0086] Keyboard and mouse sharing means that a device provides the keyboard input ability and mouse input ability to other connected devices. Keyboard and mouse sharing is also known as the keyboard and mouse sharing service. For the first device equipped with input devices, the first device can provide the function of sharing its input devices for one or more other devices (such as the second device). The input devices include a mouse and a keyboard (physical keyboard and / or virtual keyboard). For example, when the first device is a personal computer (PC) and the second device is a mobile phone, the keyboard and mouse sharing service provided by the PC supports the mobile phone to share its keyboard and mouse, and the operations input to the keyboard and mouse of the PC can be used to control the mobile phone.

[0087] Screen sharing means that the user interface of the first device is projected onto the screen of the second device for display. Optionally, screen sharing can also allow users to operate the user interface of the first device on the second device. Optionally, screen sharing can also support performing specific operations on the second device, such as dragging files from the user interface of the second device to the user interface of the first device to transfer the files in the second device to the first device, realizing cross-device operations and cross-device file transfer between the first device and the second device, etc.

[0088] Remote control means that for the first device and the second device located at different network addresses, especially in different geographical locations, the first device can share the input devices of the second device. For example, if the first device is in Guangdong Province and the second device is in Shandong Province, and the first device and the second device are connected to different network addresses on the Internet, the first device can share the input devices of the second device, such as input devices like a mouse and a keyboard.

[0089] File access means that the first device can view, create, edit, and save the documents of the second device, and perform the above operations on the documents of the second device through remote control. For example, the user creates a document on the second device through touch operations on the first device.

[0090] Cross-device invocation means that when a user operates an application on a first device, the interface of a second device can prompt the user to operate on the application running on the first device on the second device, so as to transfer to the second device for continuous operation, such as watching videos, editing documents, etc. For example, when a video application is running on the first device and the user is watching a video on the first device, when the second device is close to the first device, a prompt message is displayed on the second device. The user clicks on the prompt message on the second device. In response to the user's click operation, the second device opens the video application and displays the video content that the user is watching, so as to transfer to the second device to continue watching, etc.

[0091] Trust ring

[0092] A trust ring can be regarded as a group of devices, which may include one or more devices. A device can join the trust ring. The conditions for a device to join the trust ring may include the following two: 1. The device and the devices in the trust ring log in to the same user account. 2. The device is detected to be online by the devices in the trust ring. The way for a device to be detected to be online can be detected through a short-range connection method or through a server. For specific reference, please refer to the introduction of the subsequent embodiments. Being online can mean being detected or sensed by other devices.

[0093] Starting a sharing service between two electronic devices is a commonly used function of users. An electronic device usually supports multiple sharing services, and users can select the sharing services they want as needed. Each sharing service has a separate startup entry, and users can start the corresponding sharing service through different entries provided by the electronic device. Such a method is relatively cumbersome for users. Users need to remember different entries, start the sharing service through different entries, and subsequent operations such as closing the sharing service and switching the sharing service also need to enter the corresponding entry to operate.

[0094] In the method provided in this application, an electronic device can provide a unified startup entry for multiple sharing services. Users can conveniently select a sharing service through this entry and start the sharing service between two devices.

[0095] First, the user interface provided in this application is introduced.

[0096] Figure 1 An exemplary set of user interfaces displayed by the electronic device 300 is shown.

[0097] Figure 1 (a) shows the main interface of the electronic device 300, which contains an icon of the settings application. The electronic device 300 can receive a user operation (such as a click operation, a touch operation, a drag operation) on the icon of the settings application. In response to this user operation, Figure 1 (b) is displayed. Figure 1(b) shows an intelligent interconnection column. The electronic device 300 can receive a user operation acting on the intelligent interconnection column and, in response to the user operation, display Figure 1 (c).

[0098] Such as Figure 1 As shown in (c), the electronic device 300 displays: icons of devices joined to the trust ring, and an icon 104 of the user account. Among them, the icons of devices joined to the trust ring may include: 1. Icons of multiple electronic devices joined to the trust ring through near-field communication technology, such as the icon 103 of the electronic device 100, the icon 102 of the electronic device 200, and the icon 101 of the electronic device 300. 2. An icon 107 of a laptop computer joined to the trust ring through a cloud server. The electronic device 300 may be, for example, a mobile phone, such as Figure 1 the mobile phone shown in Figure 1 ; the electronic device 200 may be, for example, a tablet computer, such as Figure 1 the Pad V8 shown in

[0099] When the electronic device 300 receives a user operation acting on the icon 103, in response to the user operation, it displays Figure 1 (d).

[0100] Such as Figure 1 As shown in (d), the electronic device 300 displays icons of various shared services supported by the electronic device 100 corresponding to the icon 103, such as a screen sharing icon 1031, a keyboard and mouse sharing icon 1032, a remote control icon 1033, a file access icon 1034, and a cross-device call icon 1035. The five icons correspond to the following shared services: screen sharing, keyboard and mouse sharing, remote control, file access, and cross-device call. For a specific introduction to the above shared services, reference can be made to the definitions of the foregoing terms, which will not be elaborated here.

[0101] In some embodiments, Figure 1 in (c) and (d), the icon 101 of the electronic device 300 is displayed in a dark color, indicating that the icon 101 is the icon of the local device. In other embodiments, Figure 1 in (c) and (d), the icon 101 of the electronic device 300 is displayed in a light color. The present application does not limit the specific light or dark color of the device icon.

[0102] In some embodiments, when the electronic device 300 enters Figure 1Before the interface shown in (c), the electronic device 300 turns on communication modules such as wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), and near field communication (NFC) to obtain devices that can be detected within the communication range.

[0103] In some embodiments, after the electronic device 300 enters Figure 1 the interface shown in (c), the display interface of the electronic device 300 displays a prompt message for prompting the user of the operations that can be input. For example Figure 1 the prompt text in (c) and Figure 1 the prompt text in (d): "Click on the device ball and select the desired service to complete the transfer", and Figure 1 the prompt text shown in (d): "Click / drag the service to complete the transfer".

[0104] In some embodiments, when the electronic device 300 receives a click on the icon 107 of the laptop computer that joins the trust ring through the cloud server, in response to this operation, it can display the icons of various shared services supported by the laptop computer. Among them, the electronic device 100 indicated by the icon 103 and the laptop computer indicated by the icon 107 can be the same device or two different devices of the same model, and this application does not limit this.

[0105] Figure 2 Shows a set of user interfaces displayed by the electronic device 300 when it triggers itself and the electronic device 100 to start a shared service.

For example, the text prompt "SmartTV does not support the 'keyboard and mouse sharing' function" is displayed in the electronic device 300. The specific content of the error prompt is not limited in this application.

[0133] Figure 4 Shows a set of user interfaces displayed by the electronic device 300 when the electronic device 300 triggers the closing of the sharing service between the electronic device 300 and the electronic device 100.

[0134] Referring to Figure 4 (a) of, Figure 4 (a) of may be the interface displayed by the electronic device 300 after the electronic device 100 and the electronic device 300 start keyboard and mouse sharing. Among them, when the electronic device 300 and the electronic device 100 start keyboard and mouse sharing, the spherical keyboard and mouse sharing icon 10322 displayed in the electronic device 300 is in a completed state, and the prompt text shows "Using the 'keyboard and mouse sharing' service". Figure 4 (a) of may refer to Figure 2 (d) of, which will not be elaborated here for the time being.

[0135] The electronic device 300 receives a user operation acting on the spherical keyboard and mouse sharing icon 10322. This user operation drags the spherical keyboard and mouse sharing icon 10322 and moves it away from the icon 101 of the electronic device 300, displaying Figure 4 (b) of.

[0136] As Figure 4 (b) of shows, when the electronic device 300 receives this user operation, the spherical keyboard and mouse sharing icon 10322 moves away from the icon 101 following the user's drag operation. After the user drags the spherical keyboard and mouse sharing icon 10322 away from the icon 101, the spherical keyboard and mouse sharing icon 10322 is released. In response to the user operation of releasing the spherical keyboard and mouse sharing icon 10322, the electronic device 300 sends a message to the electronic device 100 to close the keyboard and mouse sharing, and displays Figure 4 (c) of.

[0137] As Figure 4 (c) of shows, in response to this user operation, the displayed spherical keyboard and mouse sharing icon 10322 of the electronic device 300 gradually deepens in transparency over time and automatically moves into the icon 103. When the transparency of the spherical keyboard and mouse sharing icon 10322 increases to the maximum value, the spherical keyboard and mouse sharing icon 10322 disappears.

For the specific representation of the spherical keyboard and mouse sharing service icon 10322, this application does not limit it.

[0141] In some embodiments, when the electronic device 300 ends the keyboard and mouse sharing with the electronic device 100, a prompt message indicating that the keyboard and mouse sharing is successfully closed is displayed in the electronic device 300. For example, a text prompt such as "The 'keyboard and mouse sharing' ends the transfer" is displayed in the electronic device 300. For the specific content and form of the prompt message, this application does not limit it.

[0142] Figure 5 Shows a set of user interfaces displayed by the electronic device 300 when switching the sharing service between devices.

[0143] Refer to Figure 5 (a) of which, Figure 5 (a) of which can be the interface displayed by the electronic device 300 after the electronic device 100 and the electronic device 300 start the keyboard and mouse sharing. Among them, when the electronic device 300 and the electronic device 100 start the keyboard and mouse sharing, the spherical keyboard and mouse sharing icon 10322 displayed in the electronic device 300 is in the completed state, and the prompt text shows "Using the 'keyboard and mouse sharing' service". Figure 5 (a) of which can be referred to Figure 4 (a) of which.

[0144] When the electronic device 300 receives a user operation acting on the spherical keyboard and mouse sharing icon 10322, the user operation drags the spherical keyboard and mouse sharing icon 10322 and moves it closer to the icon 102 of the electronic device 200, and the display shows Figure 5 (b) of which.

[0145] As shown in Figure 5 In (b) of Figure 5 , the electronic device 300 receives this user operation, and the spherical keyboard and mouse sharing icon 10322 leaves the icon 101 following the user's dragging operation. The electronic device 300 may receive the operation that the user drags the spherical keyboard and mouse sharing icon 10322 onto the icon 102 and releases it. In response to the user operation of releasing the spherical keyboard and mouse sharing icon 10322, the electronic device 300 closes the keyboard and mouse sharing with the electronic device 100, and sends a message to start the keyboard and mouse sharing to the electronic device 200. The electronic device 300 touches the spherical keyboard and mouse sharing icon 10322 with the icon 102 of the electronic device 200, and updates the state of the spherical keyboard and mouse sharing icon 10322 to a loading state, which can be displayed as two dark circles changing with time, as shown in Figure 5 (c) of Figure 5 .

[0146] As shown in Figure 5 (c) of Figure 5 , the electronic device 300 displays the spherical keyboard and mouse sharing icon 10322 at the upper left corner of the icon 102. The spherical keyboard and mouse sharing icon 10322 is displayed in a loading state. After the electronic device 300 sends a message to start the keyboard and mouse sharing to the electronic device 200, it waits for the return message from the electronic device 200. When the return message from the electronic device 200 indicates that the keyboard and mouse sharing is successfully started, as shown in Figure 5 (d) of Figure 5 .

[0147] As shown in Figure 5 (d) of Figure 5 , the electronic device 300 closes the keyboard and mouse sharing with the electronic device 100, the electronic device 200 starts the keyboard and mouse sharing with the electronic device 100, and the keyboard and mouse sharing between the electronic device 300 and the electronic device 100 is switched to the keyboard and mouse sharing between the electronic device 200 and the electronic device 100. The electronic device 300 displays the prompt message 105, and the spherical keyboard and mouse sharing icon 10322 is displayed in a completed state. The completed state of the spherical keyboard and mouse sharing icon 10322 may refer to the symbol of the keyboard and mouse sharing.

[0148] In some embodiments, after the electronic device 300 triggers itself and the electronic device 100 to start the sharing service as shown in Figure 2 , the electronic device 300 can execute the method for switching the sharing service between devices as shown in Figure 5 .

[0149] Figure 6 Exemplarily shows the structure of the communication system 10 provided by the present application.

[0150] Referring to Figure 6 , the communication system 10 may include: a plurality of electronic devices, an account management server 400, and a data synchronization server 500.

[0151] Among them, multiple electronic devices may include any one or more of the following: electronic device 100, electronic device 200, electronic device 300, and electronic device 600. Each electronic device may be of the same type or different types. Each electronic device may be provided by the same device manufacturer.

[0152] Each electronic device can support a sharing service, and the definition of the sharing service can refer to the relevant description above.

[0153] The account management server 400 is used to provide a login service for each electronic device. When an electronic device sends a login request to the account management server 400 using an account and password, the account management server 400 determines whether the account and password match. If they match, the account management server 400 can approve the login request of the electronic device and allow the electronic device to log in to the account management server 400. In some embodiments, the account management server 400 can also send a token to the successfully logged-in electronic device, send the same token to each device logged in with the same account, and send different tokens to each device logged in with different accounts. That is, electronic devices with the same account can obtain the same token after logging in.

[0154] Each electronic device can join a trust ring. The trust ring can be regarded as a device group, which may include one or more devices. For example, the electronic device 300 can learn that other devices (such as the electronic device 100) have joined the trust ring in the following two ways:

[0155] 1. The electronic device 300 logs in to the account management server 400 using a first account and learns that there is another electronic device 100 nearby that also logs in to the account management server 400 using the first account. Specifically, after the electronic device 300 logs in to the account management server 400, it can receive the token issued by the account management server 400; then, the electronic device 300 can use short-range communication technology to send a broadcast message carrying the token outward. After receiving the broadcast message, other nearby devices (such as the electronic device 100) can compare it with their own token. If they are the same, it means that other devices are currently also logged in to the account management server 400 using the first account; after other devices compare the tokens and they are the same, they can return a confirmation message to the electronic device 300. In this way, the electronic device 300 can detect that other devices are online, and the electronic device 300 and other devices join the same trust ring. This method can also be called joining the trust ring in the short range.

[0156] 2. The electronic device 300 logs in to the account management server 400 using the first account, and other devices (such as the electronic device 100) also log in to the account management server 400 using the first account. The data synchronization server 500 can obtain information about each device logged in with the same account (such as device name, device icon, etc.) from the account management server 400, and distribute the information about each device logged in with the same account to these devices. In this way, each device logged in with the same account can perceive each other and thus joins the same trust ring. This method can also be referred to as cloud joining the trust ring.

[0157] After each device in this application joins the trust ring, the method provided in this application can be used to conveniently establish a connection and start a sharing service between any two devices. The way to start the sharing service can refer to the relevant introduction in the subsequent method embodiments. For example, the electronic device 300 can trigger itself to establish a connection and start a sharing service with other devices (such as the electronic device 100), and can also trigger two other devices (such as the electronic device 100 and the electronic device 200) to establish a connection and start a sharing service. The way to establish a connection between two devices can be based on short-range communication technology or long-range communication technology, which is not limited here.

[0158] Not limited to this, after a connection is established and a sharing service is started between any two devices, the sharing service can also be switched to other devices, or the sharing service can also be closed. For specific details, please refer to the introduction in the subsequent method embodiments.

[0159] The data synchronization server 500 can be used to manage the information of each device within the trust ring. If each device joins the trust ring using the above first method, each device also needs to report its own information and the information of other detected devices to the data synchronization server 500, so that the data synchronization server 500 can know which devices have joined the trust ring. If each device joins the trust ring using the above second method, the data synchronization server 500 can record the information of each device that has joined the trust ring by itself.

[0160] The data synchronization server 500 can also be used to manage the connection status of each device within the trust ring and the status of the sharing service enabled between devices. Specifically, if there is a device in the communication system 10 that has established a connection or started a sharing service, the data synchronization server 500 can record the connection status of each device and the status of the sharing service enabled. This information can be reported by each device or obtained by the data synchronization server 500 itself.

[0161] In some implementations, each device can also be used to manage the information of each device in the trust ring, manage the connection status of each device in the trust ring, and the status of the shared service between devices, and can display a user interface based on this information to let the user know the above information. The user interface displayed by the electronic device can refer to the various UI examples shown in the above examples.

[0162] The account management server 400 and the data synchronization server 500 may be provided by manufacturers of various devices.

[0163] In some implementations, the account management server 400 and the data synchronization server 500 may be combined into one server, or may be divided into more servers, which is not limited here.

[0164] Figure 6 The communication system shown is only an example and does not constitute a limitation to the present application. Figure 6 More or fewer devices may also be included. For example, Figure 6 It may also include intermediate devices such as routers and base stations that provide connections between devices and servers. For another example, the communication system 10 may also only include the electronic device 300 and the electronic device 100 .

[0165] based on Figure 6 The communication system 10 described above introduces a method for establishing a connection between multiple devices provided by the present application.

[0166] Figure 7A The flow of the method for establishing a connection between multiple devices is exemplified.

[0167] like Figure 7A As shown, the method may specifically include the following steps:

[0168] Phase 1 (S701-S703): The third device displays the shared services supported by the device

[0169] S701. Multiple devices log in to the same account.

[0170] Multiple devices can use the same user account to initiate a login request to the account management server 400 , and after the account management server 400 agrees to the login request, all devices can log in to the account management server 400 . The multiple devices may include any multiple electronic devices in the communication system 10 .

[0171] S702: The third device detects other devices that log in to the same account.

[0172] The third device can be any device in the communication system 10. For example, it can be the electronic device 300. The third device can detect other devices based on the short-range communication technology or based on the data synchronization server 500. For specific details, please refer to the detailed description of the communication system 10 above.

[0173] Through S701 - S702, the third device and the other devices it detects meet the conditions for joining the trust ring, and it can be considered that these devices have joined the trust ring.

[0174] S703. The third device displays the icons of the first device, the second device, and the third device.

[0175] In some embodiments, the third device can also display the icon of the fourth device.

[0176] The first device, the second device, the third device, and the fourth device are all devices that have joined the trust ring through the above S701 step - S702 step.

[0177] In some embodiments, the first device, the second device, and the third device are different devices. For example, the first device, the second device, and the third device are respectively the electronic device 100, the electronic device 200, and the electronic device 300 in the communication system 10.

[0178] In some embodiments, the first device and the third device are the same device. For example, the first device and the third device are the electronic device 300 in the communication system 10, and the second device is the electronic device 200.

[0179] In some embodiments, the second device and the third device are the same device. For example, the second device and the third device are the electronic device 300 in the communication system 10, and the first device is the electronic device 100.

[0180] The third device can display a user interface, in which the icons of the first device, the second device, and the third device are displayed. An example of this user interface can be referred to Figure 1 in (c), and the entry method can be referred to the introduction of the UI embodiments in Figure 1 (a) and Figure 1 the (b) above.

[0181] Phase 2 (S704 - S711): The third device enables the sharing service between two devices

[0182] S704. The third device receives a first operation on the icon of the first device.

[0183] The first operation can be a click operation, a touch operation, or other types of touch operations.

[0184] S705. In response to the first operation, the third device displays icons of various shared services supported by the first device.

[0185] Specifically, the third device may display icons of various shared services it supports above the icon of the first device. Refer to Figure 1 (c) of [reference], taking the electronic device 300 as the third device and the electronic device 100 as the first device as an example, the icons of various shared services supported by the first device displayed by the third device can be referred to Figure 1 (d) of [reference], including a screen sharing icon 1031, a keyboard and mouse sharing icon 1032, a remote control icon 1033, a file access icon 1034, and a cross - device call icon 1035.

[0186] Among them, the shared services supported by the first device can be obtained by the third device querying the first device. The query method can be based on near - field communication technology or remote communication technology based on the data synchronization server 500.

[0187] The icons of multiple shared services displayed by the third device include an icon indicating the first shared service, and this icon indicating the first shared service can be referred to as the first element. The first shared service can be any one of the following: screen sharing, keyboard and mouse sharing, remote control, file access, and cross - device call. Refer to Figure 2 and Figure 3A , examples of the first element may include the keyboard and mouse sharing icon 1032 and the bar - shaped keyboard and mouse sharing icon 10321, and an example of the first shared service may include keyboard and mouse sharing.

[0188] S706. The third device receives a second operation of dragging the first element to the icon of the second device and releasing it.

[0189] Taking the electronic device 300 as the second device and the third device, the electronic device 100 as the first device, and the keyboard and mouse sharing icon 1032 and the bar - shaped keyboard and mouse sharing icon 10321 as the first element as an example, this second operation can be referred to Figure 2 from (a) of [reference] to Figure 2 the operation of dragging the keyboard and mouse sharing icon 1032 out of the display area of the icon of the first shared service and dragging it to the icon 101 of the second device in (b) of [reference]. Among them, after the icon of keyboard and mouse sharing is dragged out of the display area of the icon of the first shared service, the keyboard and mouse sharing icon 1032 is updated to the bar - shaped keyboard and mouse sharing icon 10321, that is, during the dragging process, the first element is updated from the first form to the second form.

[0190] Taking the electronic device 300 as the third device, the electronic device 100 as the first device, the electronic device 200 as the second device, and the keyboard and mouse sharing icon 1032 and the bar - shaped keyboard and mouse sharing icon 10321 as the first element as an example, this second operation can be referred toFigure 3A from (a) of Figure 3A the operation of dragging the shared icon 1032 away from the display area of the icon of the first shared service in (b) of

[0191] In some embodiments, the third device may determine whether each electronic device in the trust ring supports keyboard and mouse sharing during the process of dragging the first element. If keyboard and mouse sharing is supported, the icon of the electronic device is displayed in dark color; if keyboard and mouse sharing is not supported, the icon of the electronic device is displayed in light color.

[0192] After receiving the second operation, the third device determines whether the second device supports the first shared service. If it supports, the subsequent steps are continued; if it does not support, no response may be output, or the user may also be prompted that the second device does not support the first shared service.

[0193] S707. In response to the second operation, the third device displays a second element, and the second element touches the icon of the second device.

[0194] The second element may cover part of the icon of the second device or touch the edge of the icon of the second device. Refer to Figure 2 In (c) of

[0195] In some embodiments, refer to Figure 3A In (c) of

[0196] In some embodiments, after receiving the second operation, the third device may display the second element in a loading state, indicating that the second device and the first device are starting the shared service. The loading state may be, for example, two dark circles with periodically changing display colors and sizes. Refer to Figure 2 In (c) of Figure 3AIn (c), the spherical keyboard and mouse sharing icon 10322 is displayed in a loading state and touches the edge of the icon 102 of the second device.

[0197] S708. The third device sends a first message to the second device.

[0198] The third device sends a first message to the second device. The first message may carry the following information: the identifier of the first device and the identifier of the first sharing service. The first message is used to instruct the second device and the first device to establish a connection and start the first sharing service based on this connection. The connection established between the second device and the first device may be referred to as the first connection.

[0199] The first message may be sent based on a short-range communication technology or based on the data synchronization server 500 and a remote communication technology.

[0200] S709. The second device and the first device establish a first connection.

[0201] After receiving the first message, the second device, in response to the first message, establishes a first connection with the first device. The first connection includes, but is not limited to, a Wi-Fi connection, a Bluetooth connection, and an NFC connection. This application does not limit this.

[0202] S710. The second device and the first device start the first sharing service based on the first connection.

[0203] The first device and the second device start the first sharing service based on the established first connection. The source side of the first sharing service may be the first device, and the sink side may be the second device. That is to say, the first device is the initiator of the first sharing service.

[0204] S711. The second device returns the result of starting the first sharing service to the third device.

[0205] The result of starting the first sharing service between the second device and the first device may be successful or failed. There may be various reasons for failure, such as poor network conditions, etc.

[0206] According to the result of starting the first sharing service, the third device may update the display state of the second element. If the start is successful, the second element may be updated from the loading state to the completed state. For an example of the completed state, reference can be made to Figure 2 in (d) and Figure 3A the state shown by the spherical keyboard and mouse sharing icon 10322 in (d). If the start fails, the third device may stop displaying the second element. For the interface displayed by the third device when the keyboard and mouse sharing fails to start, reference can be made to Figure 3B the interface displayed by the third device in (d). The completed state of the second element may refer to the second element displaying the symbol of keyboard and mouse sharing, and this symbol is a pattern of two rectangular frames overlapping diagonally.

[0207] If the activation is successful, a prompt message indicating the activation of the first sharing service can also be displayed on the third device. For example, a text prompt message such as "The transfer of 'keyboard and mouse sharing' was successful". The specific form of the prompt message in this application is not limited.

[0208] Based on the technical solutions shown in steps S704 - S711 of this application, two electronic devices can use an entry provided by a third device to activate the sharing service between the two electronic devices with a single operation. The activation method of this sharing service is relatively convenient and fast.

[0209] If the activation result in step S710 is successful, subsequent steps S712 - S720 can be executed, or steps S721 - S726 can be executed.

[0210] Phase 3 (S712 - S720): The third device switches the device of the sharing service

[0211] S712. The third device receives a third operation of dragging the second element from the icon of the second device to the icon of the fourth device and releasing it.

[0212] Taking the electronic device 300 as the second device and the third device, the electronic device 100 as the first device, the electronic device 200 as the fourth device, and the spherical keyboard and mouse sharing icon 10322 as the second element as an example, this third operation can be referred to Figure 5 from (a) to Figure 5 the operation of dragging the spherical keyboard and mouse sharing icon 10322 away from the icon 101 of the first device and dragging it to the icon 102 of the fourth device in (b).

[0213] In some embodiments, the third device can determine whether each device in the trust ring supports keyboard and mouse sharing during the process of dragging the second element. If it supports keyboard and mouse sharing, the icon of the electronic device is displayed in dark color. If it does not support keyboard and mouse sharing, the icon of the electronic device is displayed in light color.

[0214] After receiving the third operation, the third device determines whether the fourth device supports the first sharing service. If it supports, the subsequent steps are continued; if it does not support, no response can be output, or the user can also be prompted that the fourth device does not support the first sharing service.

[0215] S713. In response to the third operation, the third device displays the second element, and the second element touches the icon of the fourth device.

[0216] The third device displays the second element, and the second element touches the icon of the fourth device. The second element can cover part of the icon of the fourth device or touch the edge of the icon 102 of the fourth device. Refer to Figure 5In (c) thereof, the third device displays the spherical keyboard and mouse sharing icon 10322, and the spherical keyboard and mouse sharing icon 10322 touches the edge of the icon 102 of the fourth device.

[0217] In some embodiments, after the third device receives the second operation, it can update the second element from the completed state to the loading state. Among them, the second element leaving the icon 101 of the second device indicates that the second device and the first device close the sharing service. The second element being updated from the completed state to the loading state indicates that the fourth device and the first device are opening the sharing service. The loading state can be, for example, two dark circles with periodically changing display colors and sizes. Refer to Figure 5 In (c) thereof, the spherical keyboard and mouse sharing icon 10322 is displayed in the loading state and touches the edge of the icon 102 of the fourth device.

[0218] S714. The third device sends a third message to the second device.

[0219] The third device sends a third message to the second device. The third message can carry the following information: the identifier of the first device, the identifier of the first sharing service. The third message is used to instruct the second device and the first device to disconnect the first connection and close the first sharing service.

[0220] The third message can be sent based on the short-range communication technology or based on the data synchronization server 500 and the remote communication technology.

[0221] S715. In response to the first message, the second device disconnects the first connection between the second device and the first device.

[0222] S716. The second device and the first device close the first sharing service.

[0223] S714 - S716 are optional steps. In some embodiments, the second device and the first device can also maintain the first connection and keep the first sharing service open.

[0224] S717. The third device sends a second message to the fourth device.

[0225] The third device sends a second message to the fourth device. The second message can carry the following information: the identifier of the first device, the identifier of the second device, the identifier of the first sharing service. The second message is used to instruct the fourth device and the first device to establish a second connection and open the first sharing service based on the second connection. Among them, for the device that switches the sharing service, it is necessary to record the device information of the device to which the sharing service was connected before switching the sharing service, for the subsequent analysis and processing of the sharing service. The identifier of the second device is the device information of the device before switching the sharing service in this embodiment.

[0226] The second message can be sent based on near-field communication technology or based on the data synchronization server 500 and remote communication technology.

[0227] In some embodiments, step S717 is a step executed after receiving a third operation, and step S717 can also be executed before step S714. That is, this application does not limit the order in which the third device sends the third message and the second message after responding to the third operation.

[0228] S718. The fourth device and the first device establish a second connection.

[0229] After receiving the second message, the fourth device responds to the second message and establishes a second connection with the first device. The second connection includes, but is not limited to, a Wi-Fi connection, a Bluetooth connection, and an NFC connection. This application does not limit this.

[0230] S719. The fourth device and the first device start a first sharing service based on the second connection.

[0231] S720. The fourth device returns the result of starting the first sharing service to the third device.

[0232] The result of starting the first sharing service between the fourth device and the first device can be successful or failed. There can be various reasons for failure, such as poor network conditions, etc.

[0233] According to the result of starting the first sharing service between the fourth device and the first device, the third device can update the display state of the second element. If the start is successful, the second element can be updated from the loading state to the completed state. For an example of the completed state, refer to Figure 5 the state shown by the spherical mouse and keyboard sharing icon 10322 in (d). If the start fails, the third device can stop displaying the second element.

[0234] If the start is successful, a prompt message indicating the start of the first sharing service can also be displayed on the third device, such as a text prompt message of "The'mouse and keyboard sharing' transfer is successful". This application does not limit the specific form of the prompt message.

[0235] Based on the technical solution shown in steps S712 - S720 of this application, two electronic devices can use an entry provided by the third device to switch the sharing service device with one operation, and conveniently and quickly switch the second device that has established a sharing service with the first device to the fourth device.

[0236] The third device and the fourth device can be the same device or different devices.

[0237] When the third device and the fourth device are the same device, the interaction steps between the third device and the fourth device: S717 and S720 should be understood as interactions between internal modules of the third device. For the specific interaction process, please refer to the subsequent Figure 9 .

[0238] Phase 4 (S721 - S726): The third device closes the shared service

[0239] S721. The third device receives the fourth operation of dragging the second element away from the icon of the second device and releasing it.

[0240] Taking the electronic device 300 as the third device and the second device, the electronic device 100 as the first device, and the spherical keyboard and mouse sharing icon 10322 as the second element as an example, this third operation can be referred to Figure 4 from (a) to Figure 4 the operation of dragging the spherical keyboard and mouse sharing icon 10322 away from the icon 101 of the second device and releasing the spherical keyboard and mouse sharing icon 10322 in (b).

[0241] S722. In response to the fourth operation, the third device displays the second element, and the second element touches the icon of the first device.

[0242] The second element can gradually increase the transparency of the second element over time. Among them, when the transparency of the second element increases to the maximum value, the second element disappears. The second element can cover part of the icon of the first device or touch the edge of the icon of the first device. Referring to Figure 4 (c), the third device displays the spherical keyboard and mouse sharing icon 10322, and the spherical keyboard and mouse sharing icon 10322 touches the icon 103 of the first device.

[0243] In some embodiments, after receiving the fourth operation, the third device can stop displaying the second element. Specifically, please refer to Figure 4 (d).

[0244] S723. The third device sends a fourth message to the second device.

[0245] The third device sends a fourth message to the second device. The fourth message can carry the following information: the identifier of the first device and the identifier of the first shared service. The fourth message is used to instruct the second device and the first device to disconnect the second connection and close the first shared service.

[0246] The fourth message can be sent based on the near - field communication technology or based on the data synchronization server 500 and the remote communication technology.

[0247] S724. In response to the fourth message, the second device disconnects the second connection with the first device.

[0248] S725, the second device and the first device close the first shared service.

[0249] S726, the second device returns the result of closing the first shared service to the third device.

[0250] According to the result of the second device and the first device closing the first shared service, the third device can update the display status of the second element. If the closing is successful, the display of the second element is stopped, refer to Figure 5 (d) of. If the closing fails, the third device can display a prompt message indicating that the first shared service fails to close, such as the text prompt message of "The 'Mouse and Keyboard Sharing' fails to close". The specific form of the prompt message in this application is not limited.

[0251] Based on the technical solution shown in steps S721 - S726 of this application, the electronic device can conveniently and quickly close the shared service device with one operation through the entry provided by the third device.

[0252] The third device and the second device can be the same device or different devices.

[0253] When the third device and the second device are the same device, the interaction steps between the third device and the second device: S708, S711, S714, S723 and S726 should be understood as the interaction between the internal modules of the third device. The specific interaction process can be referred to later Figure 9 .

[0254] In some embodiments, when the second device or the fourth device is an Internet of Things (IoT) device, it is necessary to send a message to the master device of the IoT device and let it forward the message to the IoT device. For example, when the second device and the first device establish a shared service, if the second device is an IoT device, S708, S711 and S714 should be understood as the third device sending a message to the master device of the second device, and then the master device of the second device forwards the message to the second device.

[0255] In some embodiments, some steps in the second stage can be replaced. For example, S708 can also be replaced by the third device sending a first message to the first device, and the first message includes the identifier of the second device and the identifier of the first shared service. The first message is used to trigger the first device and the second device to establish a first connection and open the first shared service based on the first connection. S711 can be replaced by the first device returning the result of opening the first shared service to the third device.

[0256] In some embodiments, some steps in Phase 3 can be replaced. For example, S714 can also be replaced with the third device sending a third message to the first device, where the third message includes the identifier of the second device and the identifier of the first shared service, and this first message is used to trigger the first device and the second device to disconnect the first connection and close the first shared service.

[0257] In some embodiments, S717 can also be replaced with the third device sending a second message to the first device, where the second message includes the identifier of the fourth device and the identifier of the first shared service, and this second message is used to trigger the first device and the fourth device to establish a second connection and start the first shared service based on the second connection. S720 can be replaced with the first device returning the result of starting the first shared service to the third device.

[0258] In some embodiments, some steps in Phase 4 can be replaced. For example, S723 can also be replaced with the third device sending a fourth message to the first device, where the fourth message includes the identifier of the second device and the identifier of the first shared service, and this first message is used to trigger the first device and the second device to disconnect the second connection and close the first shared service. S726 can be replaced with the first device returning the result of closing the first shared service to the third device.

[0259] Figure 7B Exemplarily shows the software structure of the third device and the data synchronization server.

[0260] The data synchronization server includes a device offline awareness service, a device message forwarding service, and a device data synchronization service.

[0261] Among them, the device offline awareness service is used to obtain the connection status of the device, the device message forwarding service is used to provide the service of receiving device data and forwarding the data to the target device, and the device data synchronization service is used to synchronize data such as the connection status between connected devices within the trust ring to the newly online device. The data synchronization server is used to save the information of the devices in the trust ring, including device identifiers, device connection relationships, etc. The data synchronization server is located in the cloud and can communicate with the accessed devices through wired connections, IP networks, etc. For example, when the fourth device joins the trust ring of the third device, the data synchronization service can enable the fourth device to obtain the devices connected within the trust ring and the connection relationships through the device data synchronization service. The third device can forward messages to the fourth device through the device message forwarding service, and the fourth device can obtain the device connection status within the trust ring of the third device through the device offline awareness service.

[0262] The third device includes a security authentication module, a trust ring module, a trust ring interaction center module, and a shared service management framework.

[0263] The security authentication module includes an identical account authentication module, which is used to perform a trust ring authentication on the electronic device. Specifically, for electronic devices logging in with the same user account, it is determined that the authentication conditions are met, while for electronic devices logging in with different accounts or not logging in, it is determined that the authentication conditions are not met. When the electronic device meets the authentication conditions and is sensed by a third device, it enters the trust ring. For example, if the account logged in by the fourth device is the same as that of the third device, the third device sends a broadcast carrying a token to the vicinity through a short-range communication technology. After receiving the broadcast, the fourth device compares the token in it with its own token. If they are found to be the same, it returns a confirmation message to the third device, and the third device adds the fourth device to the trust ring of the third device after receiving the confirmation message.

[0264] The trust ring module includes a fusion interconnection module and a shared service module. Among them, the fusion interconnection module is used to form a communication solution among groups of electronic devices logging in with the same account. The shared service module is used to provide different shared services, including keyboard and mouse sharing service, network sharing service, screen sharing service, other shared services, etc. Based on different shared services, different electronic device sharing effects can be achieved.

[0265] Among them, the fusion interconnection module includes a device management service, a data transmission service, an access networking service, and a unified interconnection framework. The device management service is used to record and provide information such as the running status among electronic devices within the trust ring, the information of electronic device support services, and the types of electronic devices. The data transmission service is used to provide the transmission ability of the device management service. The access networking service is used to record the authenticated electronic devices into the trust ring. The same interconnection framework is used to provide services for connecting different electronic devices within the trust ring.

[0266] After the electronic device enters the trust ring through the access networking service, it reports the device online to the trust ring interaction center module through the device management service.

[0267] The trust ring interaction center module is in the application layer and includes service interaction connections and device / service data sets. For the specific method processes related to the trust ring interaction center module in this application, reference can be made to the subsequent Figures 8A - 8D specific descriptions related to the trust ring interaction center module, which will not be elaborated here.

[0268] Among them, the service interaction module is used to obtain the operations on the third device and respond to the operations, and notify the display screen to display the operation results. The device / service data set is used to store the information of the electronic devices in the trust ring and the shared services supported by the electronic devices. For the specific method processes related to the service interaction connection module and the device / service data set in this application, reference can be made to the specific descriptions of steps S901 - S903 and steps S910 - S912 in the following text Figure 9 which will not be elaborated here.

[0269] The third device can detect the drag operation on the displayed shared service icon, obtain the information of the two electronic devices that need to enable the shared service function and the shared service to be enabled. Based on the obtained information of the two electronic devices and the shared service, the shared service in the shared service module is scheduled and connected through the shared service management framework.

[0270] The shared service management framework includes a service conflict scheduling module and a service connection management module. For the specific method flow involved in the shared service management framework in this application, reference can be made to the subsequent Figures 8A - 8D specific description related to the shared service management framework, which will not be elaborated here.

[0271] Among them, the service conflict scheduling module is used to detect whether both parties of the electronic devices requesting the shared service meet the connection requirements. If the connection requirements are met, the service conflict scheduling module sends a message allowing connection establishment to the service connection management module. If the connection requirements are not met, the service conflict scheduling module sends a message indicating that connection cannot be established to the service interaction module. The service connection management module is used to communicate with the shared service module, send connection requests and receive connection results. For the specific method flow involved in the service conflict scheduling module and the service connection management module in this application, reference can be made to the subsequent Figure 9 specific descriptions of steps S904 - S906, and steps S908 - S910, which will not be elaborated here.

[0272] The shared service module is used to establish a connection between the two electronic devices on both sides of the shared service and enable the shared service between the two electronic devices.

[0273] Based on Figure 7B the software architecture of the third device introduced above, the following further details the steps executed by the third device in Figures 8A - 9 the Figure 7A above.

[0274] Figure 8A Taking the interaction process of each module in the third device as an example, the first stage of the method embodiment is specifically introduced. Figure 7A above.

[0275] S801, the shared service module writes the profile basic information to the device management service.

[0276] Specifically, the profile basic information includes the types of shared services supported by the third device, and the types of shared services supported by different device types. For example, the shared services supported by a device of the mobile phone type include screen sharing, keyboard and mouse sharing, cross-device invocation, file access, and other shared service types. The shared services supported by a device of the laptop type include screen sharing, keyboard and mouse sharing, remote control, cross-device invocation, file access, and other shared service types.

[0277] Among them, in the process of the multi-device connection establishment method, step S801 is located before step S702 and after step S701. That is, after the third device logs in to the account and enters the third device trust ring, S801 is executed to obtain the information of each device within the trust ring and the information of the shared services supported by each device within the trust ring.

[0278] S802, the device management service sends a message indicating the first device going online and a message indicating the second device going online to the shared service management framework.

[0279] In some embodiments, the first device and the third device belong to the same trust ring. When the first device accesses the communication network and sends a notification message to the third device, the device management service module in the third device obtains the notification message and sends a message indicating the first device going online and a message indicating the second device going online to the shared service management module framework.

[0280] S803, the shared service management framework detects the type of the first device and the type of the second device based on the message indicating the first device going online and the message indicating the second device going online.

[0281] In some embodiments, the first device is a laptop and the second device is a tablet. When the first device goes online, the third device detects that the type of the first device is a laptop in the shared service management framework. When the second device goes online, the third device detects that the type of the second device is a tablet in the shared service management framework. For a specific description, reference can also be made to the relevant description in step S702, which will not be elaborated here.

[0282] S804, the shared service management framework obtains the information of the shared services supported by the first device and the information of the shared services supported by the second device from the device management service.

[0283] In some embodiments, the third device detects that the first device goes online and obtains the information of the shared services supported by the device of this type from the device management service module based on the type of the first device. For example, when the first device is a laptop, the third device obtains the information of the shared services supported by the device of this type from the device management service module based on the detected laptop type.

[0284] In the process of the multi-device connection establishment method, steps S802 - S804 represent the foregoing Figure 7A , the specific implementation of step S702 in the third device.

[0285] S805. The shared service management framework sends the information of the first device and the information of the shared services supported by the first device, the information of the second device and the information of the shared services supported by the second device to the trust ring interaction center module.

[0286] Specifically, the information of the first device includes the type of the first device, such as a laptop computer type. The information of the shared services supported by the first device includes the first shared services, such as keyboard and mouse sharing, screen sharing, remote control, file access, and cross-device call. The information of the second device includes the type of the second device, such as a tablet computer type. The information of the shared services supported by the second device also includes the first shared services, such as keyboard and mouse sharing, screen sharing, remote control, file access, and cross-device call.

[0287] In some embodiments, the shared service management framework also sends the information of the shared services supported by the third device to the trust ring interaction center module.

[0288] It should be noted that the foregoing S805 is a step executed after the third device detects the type of the device. That is to say, S805 can also be executed after S803 and before S804. The embodiments of the present application do not limit the execution order of this S805 step.

[0289] S806. The trust ring interaction center module notifies the display screen to display the icon of the first device, the icon of the second device, and the icon of the third device.

[0290] The trust ring interaction center module displays the information of the device and the supported shared services in the third device through the display module based on the obtained information of the device and the supported shared services. Refer to Figure 1 in (c), the icon 103 can be the icon of the first device, the icon 102 can be the icon of the second device, and the icon 101 can be the icon of the third device.

[0291] Among them, in the process of the multi-device connection establishment method, steps S805 - S806 represent the foregoing Figure 7A , the specific implementation of step S703 in the third device.

[0292] Figure 8B Taking the interaction process of each module in the third device as an example, the second stage of the method embodiment is specifically introduced. Figure 7A Method embodiment.

[0293] In Figure 8B , taking the third device and the second device as the same device as an example for illustration.

[0294] S807, the trust ring interaction center module obtains a notification event of a first operation.

[0295] The first operation may be a click operation, a touch operation, or other types of touch operations.

[0296] Among them, in the process of the multi-device connection establishment method, step S807 represents the specific implementation of the foregoing Figure 7A , step S704 in the third device.

[0297] S808, the trust ring interaction center module sends a message to the shared service management framework to query the shared services supported by the first device.

[0298] Specifically, the shared service management framework of the third device obtains information about the first device and information about the shared services supported by the first device.
