[0053] Implementation Methods of the Application

[0054] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0055] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the described features. In the description of this application, "plurality" means two or more, unless otherwise specifically specified.

[0056] In the description of this application, the word "for example" is used to mean "used as an example, illustration or illustration". Any embodiment described in this application as "for example" is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is given to enable any person skilled in the art to implement and use the present invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present invention can be implemented without using these specific details. In other examples, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the present invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0057] To facilitate understanding of the screen projection method provided in the embodiment of the present application, the application scenarios of the screen projection method are first explained. At present, in order to assist users in screen projection, that is, to present the screen display content on a certain terminal device on the display of another terminal device, for example, to present the screen display content on a mobile phone or computer on the display screen of a smart TV, a screen projector, that is, a screen projection terminal, has been derived. Specifically, the screen projection terminal can establish a connection with the terminal device that provides the projection screen content in a wired manner to obtain the projection information, and establish a wireless communication connection with another terminal device that displays the projection content according to a pre-set communication protocol, thereby realizing the sending of the screen display content on a certain terminal device to another terminal device for projection display. In order to distinguish between the two terminal devices, the terminal device that provides the projection screen content can usually be called a projection client, and the terminal device that performs the projection display can be called a wireless access point (Access Point, AP).

[0058] However, in the above process, compared with the wired connection between the projection terminal and the projection client, the wireless connection between the projection terminal and the wireless access point often requires more time to establish a connection. For example, under normal circumstances, the projection terminal is required to perform full-channel scanning in each frequency band, which affects the projection efficiency.

[0059] And it is precisely to solve the above problems that the present application obtains the target channel determined by automatic channel selection of the wireless access point in the target frequency band, so that after establishing a connection with the screen projection client, the target channel can be scanned in the target frequency band in priority, thereby establishing a communication connection between the screen projection terminal and the wireless access point, and after establishing the communication connection, the screen projection information of the screen projection client is obtained and sent to the wireless access point, so as to realize the screen projection display of the screen projection content on the screen projection client on the display terminal of the wireless access point. Specifically, the screen projection method provided in the embodiment of the present application is usually set in the screen projection device in the form of a computer program, and the screen projection device is usually set in the form of a processor in a computer device, such as a screen projection terminal. The screen projection device in the computer device (such as a screen projection terminal) executes the computer program corresponding to the screen projection method, thereby executing the screen projection method provided in the embodiment of the present application. Specifically, as shown in Figure 1, Figure 1 is a step flow diagram of a screen projection method provided in an embodiment of the present application, specifically including steps S110 to S130:

[0060] S110: Acquire a target channel determined by the wireless access point through automatic channel selection within a target frequency band.

[0061] In the embodiment of the present application, combined with the relevant description of the application scenario provided above, it can be seen that the wireless access point usually refers to a terminal device for screen projection display, which usually establishes a wireless communication connection with the screen projection terminal within a certain frequency band channel. Therefore, before establishing a wireless communication connection between the wireless access point and the screen projection terminal, in order to improve the efficiency of establishing the wireless communication connection, the screen projection terminal can obtain the target channel determined by the wireless access point through automatic channel selection (ACS) within the target frequency band in advance through wired access. That is, the wireless access point and the screen projection terminal can be prioritized for communication connection first. At this time, the wireless access point will send the channel information determined in advance through the automatic channel selection to the screen projection terminal for storage.

[0062] Specifically, the wireless access point can usually calculate the performance of each channel based on the channel information of different channels in the frequency band, thereby selecting the optimal channel with the best performance as the target channel. For a specific implementation solution, please refer to the subsequent Figure 7 and its explanation.

[0063] S120, in response to the connection operation between the screen projection terminal and the screen projection client, scanning is performed within the target frequency band according to the target channel to establish a communication connection between the screen projection terminal and the wireless access point.

[0064] In an embodiment of the present application, after obtaining the optimal target channel information of the wireless access point through automatic channel selection through the aforementioned wired connection, the wired connection between the wireless access point and the screen projection terminal can be disconnected first, and then the wired connection between the screen projection terminal and the screen projection client can be realized, and the wireless communication connection between the screen projection terminal and the wireless access point can be completed according to the target channel determined by the wireless access point obtained by the screen projection terminal, for example, scanning is performed preferentially within the target channel, thereby improving the establishment rate of the wireless communication connection between the screen projection terminal and the wireless access point.

[0065] Of course, considering that there may be multiple frequency bands commonly used for communication connections, for example, the more common ones are 5G frequency bands and 2.4G frequency bands, therefore, the target channels within the acquired frequency bands are usually target channels corresponding to different frequency bands, such as channels corresponding to 5G frequency bands and 2.4G frequency bands. At this time, during the scanning process within the frequency band of the projection terminal, it is usually scanned separately according to the optimal channel in different frequency bands. For the specific implementation plan, please refer to the subsequent Figure 3 and its explanatory instructions.

[0066] Of course, considering that in actual application scenarios, the wireless access point may switch the frequency band for communication connection based on actual needs, therefore, under normal circumstances, the wireless access point can use an additional communication link, such as a Bluetooth communication link, to determine the target frequency band among multiple frequency bands to preferentially scan within the target frequency band. For specific implementation solutions, please refer to the subsequent Figure 4 and its explanation.

[0067] Of course, in addition to switching frequency bands, the wireless access point may switch the channel for communication connection based on actual needs. Specifically, similar to frequency band switching, after the channel is switched, the wireless access point can notify the projection terminal through an additional communication link, such as a Bluetooth communication link, to remind the projection terminal and the wireless access point to re-establish the wireless communication connection according to the updated channel.

[0068] S130, if the screen projection terminal establishes a communication connection with the wireless access point, the screen projection information provided by the screen projection client is obtained and sent to the wireless access point, so as to perform screen projection through the display terminal of the wireless access point.

[0069] In an embodiment of the present application, after the screen projection terminal completes the wireless communication connection with the wireless access point, the screen projection terminal can obtain the screen projection information from the screen projection client based on the wired communication connection, and then send the screen projection information to the wireless access point, such as a smart TV, via wireless communication. At this time, the wireless access point can perform screen projection display through the display terminal.

[0070] Of course, considering that the screen projection terminal may not be able to complete the establishment of a communication connection with the wireless access point on the target channel, at this time, the screen projection terminal can further scan on other channels of the target frequency band to establish a communication connection with the wireless access point, thereby realizing the subsequent screen projection process. For the specific implementation plan, please refer to the subsequent Figure 2 and its explanatory contents.

[0071] The screen projection method provided in the embodiment of the present application obtains the target channel determined by the wireless access point through automatic channel selection, and then after establishing a connection operation with the screen projection client, preferentially scans the target channel within the target frequency band, thereby quickly establishing a communication connection between the screen projection terminal and the wireless access point. After the communication connection is established, the screen projection information on the screen projection client is projected and displayed on the display terminal of the wireless access point. Through the above scheme, the communication connection between the screen projection terminal and the wireless access point can be quickly completed, thereby improving the screen projection efficiency and improving the user's screen projection experience.

[0072] As shown in FIG2 , FIG2 is a schematic diagram of the steps of another screen projection method provided in an embodiment of the present application. Specifically, compared with the schematic diagram of the steps of the screen projection method shown in FIG1 , after step S130, the following steps are further included:

[0073] Step S210: If the projection terminal does not establish a connection with the wireless access point in the target channel of the target frequency band, other channels in the target frequency band are scanned to establish a communication connection between the projection terminal and the wireless access point.

[0074] In an embodiment of the present application, when the screen projection terminal fails to establish a connection with the wireless access point in the target channel of the target frequency band, the screen projection terminal will initiate a scan in other channels to seek to establish a communication connection between the screen projection terminal and the wireless access point. After establishing the communication connection, the screen projection information provided by the screen projection client is further obtained and sent to the wireless access point to perform screen projection through the display terminal of the wireless access point to realize the subsequent screen projection process.

[0075] As shown in FIG3 , FIG3 is a schematic diagram of the steps of another screen projection method provided in an embodiment of the present application. Specifically, compared with the schematic diagram of the steps of the screen projection method shown in FIG1 , step S110 specifically includes:

[0076] S310 : Acquire a first target channel determined by a wireless access point through automatic channel selection in a first target frequency band and a second target channel determined by the wireless access point through automatic channel selection in a second target frequency band.

[0077] In the embodiment of the present application, considering that there are many frequency bands that can achieve wireless communication connections, such as the 5G frequency band and the 2.4G frequency band, the channel determined by the wireless access point also includes channels determined by automatic channel selection in different frequency bands. For example, the optimal channel determined in the 2.4G frequency band and the optimal channel determined in the 5G frequency band can be regarded as the first target channel determined by automatic channel selection in the first target frequency band and the second target channel determined by automatic channel selection in the second target frequency band, respectively. Of course, the frequency bands provided above are merely illustrative of a feasible embodiment and are not intended to limit the implementation scheme of the present application.

[0078] The step S120 specifically includes:

[0079] S320, in response to the connection operation between the screen projection terminal and the screen projection client, scanning is performed within the first target frequency band according to the first target channel to establish a communication connection between the screen projection terminal and the wireless access point.

[0080] In an embodiment of the present application, after the first target channel determined by the automatic channel selection of the wireless access point within the first target frequency band is determined, the screen projection terminal can scan within the first target frequency band according to the first target channel to establish a communication connection between the screen projection terminal and the wireless access point. Of course, when establishing a communication connection between the screen projection terminal and the wireless access point, the screen projection terminal can further scan other channels within the first target frequency band to seek to establish a communication connection between the screen projection terminal and the wireless access point.

[0081] S330, in response to the connection operation between the screen projection terminal and the screen projection client, scanning is performed within the second target frequency band according to the second target channel to establish a communication connection between the screen projection terminal and the wireless access point.

[0082] In an embodiment of the present application, after the second target channel determined by the wireless access point through automatic channel selection within the second target frequency band is determined, the screen projection terminal can scan within the second target frequency band according to the second target channel to establish a communication connection between the screen projection terminal and the wireless access point. Of course, when establishing a communication connection between the screen projection terminal and the wireless access point, the screen projection terminal can further scan other channels within the second target frequency band to seek to establish a communication connection between the screen projection terminal and the wireless access point.

[0083] As shown in FIG4 , FIG4 is a schematic flow chart of a step of establishing a communication connection based on frequency band switching provided by an embodiment of the present application, specifically, including steps S410 to S420:

[0084] S410 : In response to the frequency band switching information sent by the wireless access point through the Bluetooth link, determine a final target frequency band from the first target frequency band and the second target frequency band, and determine a final target channel corresponding to the final target frequency band.

[0085] In an embodiment of the present application, the wireless access point can switch the frequency band based on actual needs, and after the frequency band is switched, the wireless access point can initiate a frequency band switching message to the screen projection terminal through an additional Bluetooth link. At this time, the screen projection terminal can determine the frequency band re-determined by the wireless access point in response to the frequency band switching information sent by the wireless access point through the Bluetooth link, for example, determine the final target frequency band between the aforementioned first target frequency band and the second target frequency band, and determine the final target channel corresponding to the final target frequency band. For example, when the first target frequency band is the final target frequency band, at this time, the first target channel is the final target channel, and when the second target frequency band is the final target frequency band, at this time, the second target channel is the final target channel.

[0086] S420: Scan within the final target frequency band according to the final target channel to establish a communication connection between the projection terminal and the wireless access point.

[0087] In an embodiment of the present application, after the final target frequency band determined by the wireless access point is determined, the projection terminal scans within the final target frequency band according to the final target channel, and a communication connection between the projection terminal and the wireless access point can be established.

[0088] As shown in FIG5 , FIG5 is a schematic flow chart of a step of implementing channel switching based on a Bluetooth link provided in an embodiment of the present application, specifically, including steps S510 to S520:

[0089] S510 : In response to the channel switching information sent by the wireless access point through the Bluetooth link, determine a final switching channel according to the channel switching information.

[0090] In an embodiment of the present application, in addition to the aforementioned switching of frequency bands, the wireless access point can also switch channels. Specifically, when the wireless access point implements channel switching, it can also initiate channel switching information to the screen projection terminal through the Bluetooth link. At this time, in response to the channel switching information initiated by the wireless access point, the screen projection terminal can further determine the final switching channel.

[0091] Of course, the wireless access point initiating the handover of information is usually implemented when it is determined that interference exists in the channel. For a specific implementation solution, please refer to the subsequent FIG. 6 and its explanation.

[0092] S520, scanning is performed within the target frequency band according to the final switching channel to establish a communication connection between the screen projection terminal and the wireless access point, and the Bluetooth link between the screen projection terminal and the wireless access point is cut off.

[0093] In an embodiment of the present application, after determining the final switching channel finally determined by the wireless access point, the screen projection terminal can scan within the target frequency band according to the final switching channel to establish a communication connection between the screen projection terminal and the wireless access point, and after the communication connection is established, cut off the Bluetooth link between the screen projection terminal and the wireless access point.

[0094] As shown in FIG6 , FIG6 is a schematic flow chart of a step of implementing channel switching based on channel interference provided by an embodiment of the present application, specifically, including steps S610 to S620:

[0095] S610: The wireless access point determines a channel interference state of the target channel according to the acquired channel information.

[0096] In an embodiment of the present application, a wireless access point may determine the channel interference state of a target channel by collecting channel information of different channels within a frequency band. For example, it may determine whether the target channel is in a strong interference state or a weak interference state. Specifically, the channel information may include a noise floor, received signal strength indicators of other wireless access points, channel usage statistics, and transmit power, etc.

[0097] S620: When the channel interference status meets the preset conditions, the wireless access point determines the switching channel through automatic channel selection, and sends channel switching information to the projection terminal through the Bluetooth link.

[0098] In an embodiment of the present application, when it is determined that the channel interference state meets the preset conditions, for example, when it is determined that the channel interference state is a strong interference state, there will be obvious interference anomalies when the wireless access point and the screen projection terminal communicate in the channel, affecting the screen projection effect. At this time, the wireless access point will determine the switching channel through automatic channel selection, and then send channel switching information to the screen projection terminal through the Bluetooth link to enable the screen projection terminal to complete the channel switching.

[0099] As shown in FIG. 7 , FIG. 7 is a schematic flow chart of a step of determining a target channel provided by an embodiment of the present application, specifically, including steps S710 to S720:

[0100] S710: The wireless access point obtains channel information of each channel in a target frequency band.

[0101] In the embodiment of the present application, the wireless access point may collect channel information by channel acquisition. Specifically, the channel information here is similar to the channel information for evaluating the channel interference status described above, and may also include at least one of a noise floor, received signal strength indicators of other wireless access points, channel usage statistics, and transmit power.

[0102] S720: Determine a target channel determined by the wireless access point within a target frequency band according to the channel information of each channel.

[0103] In the embodiment of the present application, by using the channel information of each channel, the wireless access point can determine a channel with better performance as the target channel.

[0104] In order to better implement the screen projection method provided in the embodiment of the present application, based on the screen projection method provided in the embodiment of the present application, the embodiment of the present application further provides a screen projection device, as shown in FIG8 , the screen projection device 800 includes:
