In order to facilitate understanding of the solution of the exemplary embodiment of the present disclosure, the following first takes, as an example, establishment of multi-screen linkage between a mobile phone and a notebook computer through multi-screen linkage App (Application), to explain the problems existing in the conventional technology. In the traditional technology, if multi-screen linkage is required to be established between a mobile phone and a notebook computer, firstly, the multi-screen linkage App is required to be opened at a computer end and the multi-screen linkage App is required to be opened at the mobile phone end; then, as shown in fig. 1-a, the bluetooth function is opened on the notebook computer to search for devices, a bluetooth device list is displayed on the notebook computer for users to select devices needing to be put on a screen, the notebook computer requests bluetooth connection, and the mobile phone device establishes bluetooth connection after confirmation; finally, establishing a WIFI Direct connection (WiFi Direct), and projecting a mobile phone screen to a notebook computer, as shown in fig. 1-b, wherein the WIFI Direct connection is a common scheme for realizing screen projection among multiple devices. Thus, multi-screen linkage (screen projection is one of multi-screen linkage) is established between the mobile phone and the notebook computer. In this way, in the process of establishing the bluetooth connection, the computer end needs to search for surrounding devices, display the devices in the device list, and find the devices needing to be matched from the list and then manually confirm the target device, so that the bluetooth connection can be realized, and the operation is complex. The scheme of the multi-screen linkage can be built more quickly by reducing user operation in the process of building Bluetooth connection.

The method for establishing multi-screen linkage based on the Bluetooth keyboard can be applied to an application environment shown in fig. 2. The Bluetooth keyboard 204 may establish a communication connection with the first terminal 202 and/or the second terminal 206 using Bluetooth technology, and the first terminal 202 and the second terminal 206 that have established Bluetooth connections with the Bluetooth keyboard 204 may have identification information of the Bluetooth keyboard 204 stored therein.

In an exemplary embodiment of the present disclosure, as shown in fig. 3, a method for establishing multi-screen linkage based on a bluetooth keyboard is provided, and the method is applied to the first terminal in fig. 1 for illustration, and includes the following steps:

And step 302, responding to the appointed input operation of the user on the Bluetooth keyboard currently connected with the first terminal, and starting the multi-screen linkage application.

Here, the designated input operation is a pre-designated input operation for triggering establishment of multi-screen linkage. The specified input operation is generated by the user operating the bluetooth keyboard currently connected to the first terminal, and specifically may refer to that the user presses one or more specified keys of the bluetooth keyboard, where the pressing may be clicking or long pressing, and if a combination key formed by a plurality of keys is pressed, each key in the combination key may be pressed simultaneously, or each key in the combination key may be pressed sequentially.

Here, the multi-screen linkage application refers to an application program or an application program product that realizes a multi-screen linkage function or a multi-screen cooperative function among a plurality of terminals, and is installed or run on a terminal that needs to perform multi-screen linkage, and may be, for example, a multi-screen linkage application (also referred to as a multi-screen cooperative application). The multi-screen linkage application can be an application special for a multi-screen linkage function or a multi-screen cooperative function, or can be other applications comprising the multi-screen linkage function or the multi-screen cooperative function. The multi-screen linkage application can be operated at the foreground of the first terminal after being started, and can also be operated at the background of the multi-screen linkage application.

Specifically, the first terminal is connected with the bluetooth keyboard, at this time, the first terminal monitors the input operation of the bluetooth keyboard connected with the first terminal by the user, analyzes the monitored input operation, if the monitored input operation is determined to be the specified input operation according to the analysis result, the state of the multi-screen linkage application can be judged first, if the multi-screen linkage application is in an un-started state, the multi-screen linkage application is started, or if the monitored input operation is determined to be the specified input operation according to the analysis result, the multi-screen linkage application is started directly.

Step 304, a bluetooth broadcast carrying first identification information is sent, where the first identification information is identification information of a bluetooth keyboard currently connected to the first terminal.

Here, the bluetooth broadcast carries the identification information of the bluetooth keyboard to which the first terminal is currently connected, that is, the first identification information. The first identification information is used as a matched certificate, and the identification information of the Bluetooth keyboard connected with the first identification information is stored in other terminals, so that the matching can be successfully performed as long as one terminal is connected with the Bluetooth keyboard connected with the first terminal. Wherein, a first terminal as a broadcaster (advertisement) may periodically transmit a bluetooth broadcast signal. The broadcast type is connectable non-directional broadcast, which is one of the most widely used broadcast types, including broadcast data and scan response data, which indicates that the current device (first terminal) can accept bluetooth connection requests of other non-designated devices.

In certain exemplary embodiments of the present disclosure, mac address (Media Access Control Address) may be used as the identification information of the bluetooth keyboard described above. The Mac Address is a medium access control Address, also called a local area network Address (LAN Address), a Mac Address, an Ethernet Address (Ethernet Address) or a Physical Address (Physical Address), which is an Address for confirming the location of a network device. Mac addresses may be used in a network to distinguish between different devices. The identification information of the bluetooth keyboard may employ other information that may be used to identify the device's uniqueness in the network.

In certain exemplary embodiments of the present disclosure, the above-described specified input operation is a shortcut key operation. Where a shortcut key, also called a shortcut key or hotkey, means that an operation is performed by some specific key, sequence of keys or combination of keys. The shortcut key may generally include one or two of Ctrl key, shift key, alt key, fn key, and Windows key, and further include one or two other keys, thereby forming a key combination composed of two or three keys, but may also include no key of Ctrl key, shift key, alt key, fn key, or Windows key. A shortcut key operation may refer to an operation in which a corresponding shortcut key is pressed. The multi-screen linkage is established through the shortcut key operation triggering, so that the operation is more convenient.

Specifically, as described above, the first terminal establishes a connection with the bluetooth keyboard, and at this time, the first terminal listens for an input operation of the bluetooth keyboard connected by the user, parses the monitored input operation, and if it is determined by parsing that the monitored input operation is a specified input operation, starts the multi-screen linkage application. In addition to starting the multi-screen ganged application, a bluetooth broadcast carrying identification information (first identification information) of its connected bluetooth keyboard is also transmitted.

And 306, establishing Bluetooth connection between the first terminal and the second terminal, and establishing multi-screen linkage with the second terminal based on the Bluetooth connection and the multi-screen linkage application, wherein the identification information of the Bluetooth keyboard stored in the second terminal is matched with the first identification information.

The process of determining whether the identification information of the bluetooth keyboard stored in the second terminal matches the first identification information may be generally performed by, but not limited to, the second terminal. The second terminal stores identification information of the bluetooth keyboard to which it is connected.

Here, the multi-screen linkage may be screen-casting, or may support file and picture transfer while not screen-casting.

Specifically, after the second terminal receives the bluetooth broadcast, analyzing the identification information of the bluetooth keyboard carried in the bluetooth broadcast, and matching the analyzed identification information, namely the first identification information, with the address information of the bluetooth keyboard stored in the second terminal by the second terminal, wherein if the identification information and the address information are the same, the matching is successful; the first terminal can establish Bluetooth connection with the second terminal, so that multi-screen linkage with the second terminal is established based on the Bluetooth connection and the started multi-screen linkage application.

After the first terminal establishes Bluetooth connection with the second terminal, WIFI direct connection between the first terminal and the second terminal can be established based on the Bluetooth connection, so that point-To-point connection between the first terminal and the second terminal can be realized, and multi-screen linkage can be performed between the first terminal and the second terminal based on multi-screen linkage application. The process of establishing multi-screen linkage with the second terminal based on Bluetooth connection and multi-screen linkage application can be realized in the existing mode, and only simple explanation is made here, and detailed description is omitted.

In the method for establishing multi-screen linkage based on the Bluetooth keyboard, the first terminal responds to the appointed input operation of the Bluetooth keyboard currently connected with the first terminal by a user, starts the multi-screen linkage application, and sends Bluetooth broadcast carrying first identification information, wherein the first identification information is the identification information of the Bluetooth keyboard currently connected with the first terminal, the first terminal also establishes Bluetooth connection between the first terminal and the second terminal, and establishes multi-screen linkage with the second terminal based on the Bluetooth connection and the multi-screen linkage application, and the identification information of the Bluetooth keyboard stored in the second terminal is matched with the first identification information. Therefore, if the second terminal is also connected with the Bluetooth keyboard before, the identification information of the Bluetooth keyboard is stored, and according to the scheme of the embodiment of the disclosure, the identification information of the Bluetooth keyboard is used as a matched certificate, the identification information of the Bluetooth keyboard currently connected with the second terminal and the first terminal can be successfully matched, bluetooth connection can be directly carried out, a user does not need to select equipment, and the convenience of operation is improved.

In some exemplary embodiments of the present disclosure, the bluetooth broadcast may further carry second identification information, where the second identification information is identification information of the first terminal, and the establishing a bluetooth connection between the first terminal and the second terminal includes: and receiving a Bluetooth connection request sent by the second terminal according to the second identification information, establishing Bluetooth connection with the second terminal, and sending the Bluetooth connection request after the second terminal judges that the identification information of the Bluetooth keyboard stored in the second terminal is matched with the first identification information.

Specifically, as shown in fig. 4, the method for establishing multi-screen linkage based on the bluetooth keyboard in the exemplary embodiment includes the following steps:

and step 402, in response to the appointed input operation of the Bluetooth keyboard currently connected with the first terminal by the user, starting the multi-screen linkage application.

Step 404, a bluetooth broadcast carrying first identification information and second identification information is sent, wherein the first identification information is identification information of a bluetooth keyboard currently connected to the first terminal, and the second identification information is identification information of the first terminal.

In certain exemplary embodiments of the present disclosure, the Mac address of the device is used as the identification information of the device, that is, the identification information of the bluetooth keyboard is the Mac address of the bluetooth keyboard, and/or the identification information of the first terminal is the Mac address of the first terminal.

Here, on the one hand, the bluetooth broadcast carries the identification information of the bluetooth keyboard, and the bluetooth broadcast is used as a matched certificate, so that the terminal receiving the bluetooth broadcast can judge whether the identification information of the bluetooth keyboard stored by the terminal is matched with the identification information of the bluetooth keyboard in the broadcast, on the other hand, the bluetooth broadcast also carries the identification information of the first terminal, and after the matching is successful, the second terminal can initiate a bluetooth connection request to the first terminal based on the identification information.

Step 406, receiving a bluetooth connection request sent by the second terminal according to the second identification information, and establishing bluetooth connection with the second terminal so as to establish multi-screen linkage with the second terminal based on the multi-screen linkage application, wherein the bluetooth connection request is sent by the second terminal after judging that the identification information of the bluetooth keyboard stored by the second terminal is matched with the first identification information.

Specifically, the second terminal judges whether the identification information of the Bluetooth keyboard stored by the second terminal is matched with the first identification information, if so, a Bluetooth connection request is sent to the first terminal according to the second identification information, after the first terminal receives the Bluetooth connection request, bluetooth connection is established with the second terminal, and after the Bluetooth connection is successfully performed, multi-screen linkage is established with the second terminal. The second terminal may determine a broadcaster of the bluetooth broadcast and a connection object of the bluetooth connection according to the second identification information.

In these exemplary embodiments, based on the bluetooth broadcast manner, the verification of whether the second terminal is matched or not is achieved, and the establishment of bluetooth connection with the second terminal is also achieved, so that the automatic establishment of multi-screen linkage of the first terminal and the second terminal is achieved, the user does not need to find the equipment needing to be matched from the list and then manually confirm the target equipment, the convenience of operation is improved, meanwhile, the verification of whether the second terminal is matched or not and the establishment of bluetooth connection with the second terminal are achieved in the same process, and compared with the two independent processes, the waiting time of the user can be reduced.

In some exemplary embodiments of the present disclosure, as shown in fig. 5, the establishing a bluetooth connection with the second terminal includes:

step 502, receiving bluetooth connection requests sent by a plurality of terminals, where the bluetooth connection requests carry connection time point information, and the connection time point information is a time point when a corresponding terminal is connected with a bluetooth keyboard currently connected with the first terminal.

For example, when the terminal a, the terminal B, and the terminal C have previously established a connection with the bluetooth keyboard currently connected to the first terminal, the terminal a, the terminal B, and the terminal C each store identification information of the bluetooth keyboard, and further store a time point when the connection is previously established with the bluetooth keyboard currently connected to the first terminal.

And step 504, screening out the terminal which is connected with the Bluetooth keyboard currently connected with the first terminal and has recently been connected with the Bluetooth keyboard according to the information of each connection time point.

For example, the connection time point information received from terminal a, terminal B and terminal C is 2023.04.26,10:27, 2023.05.08,15:39, 2023.05.17,20:42, respectively; it can thus be determined that terminal C is the terminal that has recently established a connection with the bluetooth keyboard to which the first terminal is currently connected.

And step 506, establishing Bluetooth connection with the screened terminal, wherein the screened terminal is a second terminal.

Because the equipment which is recently connected with the Bluetooth keyboard is equipment which is required to establish multi-screen linkage by the user with high probability, the scheme in the embodiment is adopted, and even if a plurality of terminals are successfully matched at present, the user is not required to manually select the equipment, so that the convenience of operation is further improved.

In step 604, when the identification information of the bluetooth keyboard stored in the second terminal matches with the first identification information, a bluetooth connection is established between the first terminal and the second terminal, and multi-screen linkage is established with the first terminal based on the bluetooth connection and the multi-screen linkage application.

Here, the multi-screen linkage type application may run in the foreground or the background of the first terminal and the second terminal.

In some exemplary embodiments of the present disclosure, the bluetooth broadcast further carries second identification information, where the second identification information is identification information of the first terminal, and when the identification information of the bluetooth keyboard stored in the second terminal matches with the first identification information, a bluetooth connection is established between the first terminal and the second terminal, including: and when the identification information of the Bluetooth keyboard stored in the second terminal is matched with the first identification information, sending a Bluetooth connection request to the first terminal according to the second identification so that the first terminal can establish Bluetooth connection with the second terminal after receiving the Bluetooth connection request.

In some exemplary embodiments of the present disclosure, when the identification information of the bluetooth keyboard stored in the second terminal matches the first identification information, a bluetooth connection request is sent to the first terminal according to the second identification, so that the first terminal establishes a bluetooth connection with the second terminal after receiving the bluetooth connection request, including: when the stored identification information of the Bluetooth keyboard is matched with the first identification information, a Bluetooth connection request carrying connection time point information is sent to the first terminal according to the second identification information, wherein the connection time point information is the time point of connection establishment between the second terminal and the Bluetooth keyboard currently connected with the first terminal, so that the first terminal determines that the second terminal is the terminal which is recently connected with the Bluetooth keyboard currently connected with the first terminal according to the received connection time point information sent by the plurality of terminals, and the second terminal establishes Bluetooth connection with the second terminal.

Here, (win+f9) refers to the Windows key and the F9 key, i.e., the shortcut key for triggering the start of the multi-screen linkage is (win+f9), but it should be understood by those skilled in the art that the form of the shortcut key for triggering the start of the multi-screen linkage is not limited thereto.

Specifically, when the bluetooth keyboard and the PC are connected, if the user needs to start multi-screen linkage, the shortcut key win+f9 can be input through the bluetooth keyboard.

In step S704, the PC monitors and parses the keyboard operation event through the background, and if the keyboard operation event (win+f9) is obtained by parsing, starts the multi-screen linkage application.

Specifically, the PC background analyzes a keyboard operation event generated by the input operation of a user on the Bluetooth keyboard, and when the input of the user is identified as win+F9, the multi-screen linkage application is started.

In step 706, the pc transmits a bluetooth broadcast and includes the Mac address of the bluetooth keypad in the bluetooth broadcast.

Specifically, a PC as a broadcaster may periodically transmit a broadcast signal, for example, with t as a broadcast interval. Each time a broadcast packet is transmitted, it is referred to as a broadcast event. Since it is not desirable that all terminals can make bluetooth connection with the PC, in the scheme of the present exemplary embodiment, a Mac address of a bluetooth keyboard is added to broadcast data at the time of transmitting bluetooth broadcast. Meanwhile, the Bluetooth broadcast also carries the Mac address of the PC.

In step S708, the mobile phone receives the bluetooth broadcast and parses the Mac address of the bluetooth keyboard.

Specifically, after the mobile phone receives the bluetooth broadcast, the mobile phone analyzes information in the bluetooth broadcast, for example, in table 1, the analysis result of the bluetooth broadcast includes basic information of the PC device, and is attached with related information of the bluetooth keyboard. The basic information of the PC device includes a device name, a device identifier, and a device Mac address. The associated information for the attached bluetooth keyboard includes the attached Ma address (i.e., mac address of the bluetooth keyboard) and the attached device name.

Table 1: bluetooth broadcast analysis result indication

In step S710, the mobile phone matches the resolved Mac address with the bluetooth keyboard Mac address stored in the mobile phone. If the Mac addresses are the same, the match is successful.

Specifically, the mobile phone analyzes the auxiliary information (auxiliary Mac address: E2:35:32: b2: a3, and device name HID-keyboard) carried in the bluetooth broadcast, and matches the auxiliary Mac address with the Mac address of the bluetooth keyboard locally stored in the mobile phone. In table 2, the Mac addresses of the bluetooth keyboard stored locally in the mobile phone are matched successfully if the two Mac addresses are the same. After the matching is successful, the process advances to step S712.

Table 2: information indication stored locally in mobile phone

Step 712 to step 718, the mobile phone analyzes the Mac address of the target device (PC), initiates a bluetooth connection request to the PC, and after the PC establishes a bluetooth connection, notifies the mobile phone, and initiates a screen-throwing request after receiving the notification, and the PC displays the screen-throwing.

Specifically, after the mobile phone is successfully matched, a Bluetooth connection request is initiated according to the analyzed Mac address of the PC, and the PC receives the Bluetooth connection request and establishes Bluetooth connection with the mobile phone. After the Bluetooth connection is established, the mobile phone is informed of completing the Bluetooth connection, the mobile phone can send a screen projection request to the PC after receiving the notification, and the PC displays screen projection content after receiving the screen projection request. Thus, the establishment of multi-screen linkage between the PC and the mobile phone is realized.
