[0093] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0094] Wireless screen projection, also known as wireless screen sharing, flying screen, and screen sharing, is a way to display the screen of mobile device A on the screen of another device B in real time through some technical methods. The content output by wireless screen projection includes various media information and real-time operation pictures.

[0095] In the related technology, when screen projection is needed, device B sends the information of the channel where device B is located through BLE (Bluetooth Low Energy) broadcasting, but this method needs to rely on the Bluetooth module. If there is no Bluetooth module on the device or Bluetooth is turned off, the information of the channel where the device is located cannot be sent. Alternatively, device B sends the information of the channel where device B is located through the LAN mDNS (Multicast Domain Name System) multicast method, but in this method, the WiFi (Wireless Fidelity) connected to device B and mobile device A needs to be connected to the same LAN before a communication connection can be established, and the application scenario has great limitations.

[0096] In response to the problems in the above-mentioned related technologies, an embodiment of the present disclosure provides a device connection method, in which a first device sends a first message by broadcasting, and the first message includes information about a first channel occupied by the first device during communication. After receiving the first message, the second device scans the first device on the first channel and sends a connection request through the first channel. The first device receives the connection request, thereby establishing a communication connection between the first device and the second device. This method of the embodiment of the present disclosure broadcasts the channel where the first device is located, avoiding the limitation of needing to establish a local area network connection, and does not rely on a Bluetooth module, which is more applicable, and the second device directly scans on the channel where the first device is located, shortening the scanning time and increasing the speed of establishing a communication connection between the first device and the second device.

[0097] Before introducing the device connection method, the screen projection system involved in the embodiment of the present disclosure is first described. Figure 1 The screen projection system includes a first device and a second device, the first device may also be referred to as a screen projection device GO (Group Owner), and the second device may also be referred to as a screen projection device GC (Group Client). The first device may be a mobile phone, tablet computer, notebook, computer or other device, and the second device may be a tablet computer, laptop computer, desktop computer, TV, TV box, all-in-one machine, projector or other device.

[0098] For an electronic device, in some scenarios, the electronic device can be used as a screen projection device GO, and in other scenarios, the electronic device can also be used as a screen projection device GC, that is, the screen projection device GO and the screen projection device GC are a role of the electronic device. For example, if the electronic device is a tablet computer, when the screen of the tablet computer is projected to the screen of a TV, the tablet computer is the screen projection device GC, and when the screen of a mobile phone is projected to the tablet computer, the tablet computer is the screen projection device GO.

[0099] Optionally, when the electronic device is used as a screen projection device GO, the electronic device can establish a communication connection with one or more screen projection devices GC. When the electronic device is used as a screen projection device GC, the electronic device can establish a communication connection with one screen projection device GO.

[0100] In some embodiments, the screen projection system may include multiple first devices and one second device. Figure 2 The projection system is a NAN (Neighbor Awareness Networking) cluster, which includes four NAN Devives (devices): TV, computer, TV box, mobile phone or tablet computer, where every two NAN Devives (except TV and TV box) can communicate with each other. Figure 2 In the example, the TV, computer, or TV box is the first device, and the mobile phone or tablet is the second device.

[0101] Below through Figure 3 and Figure 4 The illustrated embodiment describes the device connection process from the perspectives of the first device and the second device, respectively.

[0102] Figure 3 is a flowchart of a device connection method according to an exemplary embodiment, which is executed by a first device, see Figure 3 , the method comprises the following steps:

[0103] Step S301: Send first information by broadcasting, where the first information includes information about a first channel occupied by a first device during communication.

[0104] In the embodiment of the present disclosure, before the first device needs to establish a communication connection with other devices, the first device sends the first information by broadcasting, so that other devices can receive the first information. Sending the first information by broadcasting means sending the first information to other devices in the same network range as the first device, and the first device and other devices are connected to the same network.

[0105] The first information includes information about the first channel occupied by the first device during communication, that is, the first channel is a channel used by the first device to transmit information. The first information includes information about the first channel, and the first information is sent out by broadcasting, so that other devices can obtain the first information.

[0106] Step S302, receiving a connection request sent by the second device. The connection request is sent by the second device through the first channel after the second device receives the first information and scans the first device on the first channel. The connection request is used to request to establish a communication connection between the first device and the second device.

[0107] After receiving the first information, the second device obtains the first channel occupied by the first device from the first information. Then, when the second device needs to connect to the first device, it can quickly scan the first device on the first channel and send a connection request to the first device through the first channel. The connection request is used to request to establish a communication connection between the first device and the second device. The first device receives the connection request and can then establish a communication connection with the second device based on the connection request, thereby realizing device connection.

[0108] In the method provided by the embodiment of the present disclosure, when a communication connection needs to be established between a first device and a second device, the first device sends a first message by broadcasting, and the first message includes information about a first channel occupied by the first device during communication. After receiving the first message, the second device scans the first device on the first channel and sends a connection request through the first channel. The first device receives the connection request, thereby establishing a communication connection between the first device and the second device. When broadcasting the channel where the first device is located, the limitation of needing to establish a local area network is avoided, and it does not rely on a Bluetooth module, which is more applicable. The second device directly scans on the channel where the first device is located, which shortens the scanning time and increases the speed of establishing a communication connection between the first device and the second device.

[0109] Figure 4 is a flowchart of another device connection method according to an exemplary embodiment, which is executed by the second device. Figure 4 , the method comprises the following steps:

[0110] Step S401: receiving first information, where the first information is sent by a first device in a broadcasting manner, and the first information includes information about a first channel occupied by the first device during communication.

[0111] After the first device sends the first information in a broadcasting manner, the second device receives the first information, wherein the second device and the first device are connected to the same network.

[0112] Step S402, in response to an instruction to start the screen projection function, scanning is performed on the first channel.

[0113] For the second device, after receiving the first information, the second device can determine the first channel occupied by the first device. When the second device needs to project the screen, that is, the second device responds to the instruction to turn on the screen projection function, and scans on the first channel, thereby quickly scanning the first device. Among them, the instruction to turn on the screen projection function is used to indicate that the screen projection function has been turned on and needs to be connected to other devices for screen projection.

[0114] Step S403: Send a connection request to the scanned first device, where the connection request is used to request to establish a communication connection between the first device and the second device.

[0115] The second device sends a connection request to the first device through the first channel. The connection request is used to request to establish a communication connection between the first device and the second device. The first device receives the connection request and can then establish a communication connection with the second device based on the connection request, thereby realizing device connection.

[0116] In the method provided by the embodiment of the present disclosure, when a communication connection needs to be established between a first device and a second device, the first device sends a first message by broadcasting, and the first message includes information about a first channel occupied by the first device during communication. After receiving the first message, the second device scans the first device on the first channel and sends a connection request through the first channel. The first device receives the connection request, thereby establishing a communication connection between the first device and the second device. When broadcasting the channel where the first device is located, the limitation of needing to establish a local area network is avoided, and it does not rely on a Bluetooth module, which is more applicable. The second device directly scans on the channel where the first device is located, which shortens the scanning time and increases the speed of establishing a communication connection between the first device and the second device.

[0117] Figure 5 is a flowchart of another device connection method according to an exemplary embodiment, which is executed by a first device and a second device. Figure 5 , the method comprises the following steps:

[0118] Step S501, in response to an instruction to start the screen projection function, the first device sends first information by broadcasting based on the WiFi Aware protocol, where the first information includes information about a first channel occupied by the first device during communication.

[0119] In the disclosed embodiment, when the first device detects an instruction to turn on the screen projection function, it indicates that the first device can perform screen projection. Therefore, in response to the instruction to turn on the screen projection function, based on the WiFi Aware (Wireless Fidelity Peripheral Awareness) protocol, the first information is sent by broadcasting, so that other devices can receive the first information, thereby quickly discovering the first device. Among them, the instruction to turn on the screen projection function is used to indicate that the screen projection function has been turned on and needs to be connected to other devices for screen projection; the WiFi Aware protocol is a protocol that allows devices including WiFi modules to discover each other. Based on the WiFi Aware protocol, devices including WiFi modules can sense each other's existence, and even connect together to establish a short-range connection between devices to share information, and can transmit information, pictures, videos and other content to each other. The WiFi Aware protocol can send information by broadcasting.

[0120] In some embodiments, the first device is provided with a screen projection control, and in response to a user triggering operation on the screen projection control, an instruction to start the screen projection function is detected.

[0121] It should be noted that step S501 is explained by taking the sending of the first information once as an example. In another embodiment, the first device responds to the instruction to turn on the screen projection function, and based on the WiFi Aware protocol, sends the first information by broadcasting at intervals of a first preset duration. The first preset duration is a pre-set duration, for example, the first preset duration is 5 minutes, 10 minutes or other durations. This method of sending the first information once at intervals of the first preset duration can increase the possibility of other devices receiving the first information, and is conducive to other devices obtaining the latest first information of the first device. That is to say, in the process of the first device sending the first information, the first channel where the first device is located may change. In this case, the first information is sent once at intervals of the first preset duration, and the information of the changed first channel can be sent out in time, so that other devices can obtain accurate channel information in time, avoiding other devices from scanning on the wrong channel later.

[0122] Another point that needs to be explained is that step S501 is to send the first information in response to an instruction to turn on the screen projection function. In another embodiment, the first information can be sent directly by broadcasting based on the WiFi Aware protocol without having to be sent when an instruction to turn on the screen projection function is detected.

[0123] Step S502: The second device enables a preset service based on the WiFi Aware protocol, and receives first information based on the preset service.

[0124] In the disclosed embodiment, the first device sends the first information based on the WiFi Aware protocol, and correspondingly, the second device also receives the first information based on the WiFi Aware protocol. In order to receive the first information, the second device first enables a preset service based on the WiFi Aware protocol, that is, subscribes to the preset service. The preset service is to add the second device to the NAN cluster where the first device is located. After starting the preset service, the second device adds the first device to the NAN cluster where the first device is located. Devices in the same NAN cluster can receive the sent information from each other. Therefore, the second device can receive the first information based on the preset service.

[0125] It should be noted that the first device and the second device belong to the same NAN cluster, which includes at least one first device and at least one second device, that is, the NAN cluster may include multiple devices. In the embodiment of the present disclosure, there is no limit on the number of devices in the NAN cluster.

[0126] Step S503: the second device stores the first information.

[0127] After receiving the first information, the second device stores the first information so that when the second device needs to connect to the first device, it can obtain the first channel where the first device is located from the stored first information, thereby quickly scanning the first device on the first channel to increase the scanning speed.

[0128] In some embodiments, before the second device stores the first information, if the second device already stores the first information of the first device, the first information is updated and stored. Updating and storing the first information means replacing the first information stored by the second device with the latest received first information. This method of updating the first information in real time can ensure that the first information stored by the second device is the latest information, avoid the problem that the first information sent by the first device has changed, while the second device is still scanning based on the original first information, which is conducive to more accurate scanning by the second device.

[0129] Optionally, after receiving the first information, the second device parses the first information, obtains information about the first channel in the first information, and stores the information about the first channel.

[0130] Optionally, the second device stores the first information or the information of the first channel in a local database of the second device.

[0131] In some embodiments, when the first information is not updated for more than a second preset time, the stored first information is deleted. The second preset time is a pre-set time, for example, the second preset time is 30 minutes, 1 hour, 2 hours or other time. When the first information is not updated for more than the second preset time, it means that the first device may no longer support establishing a communication connection with other devices. At this time, if scanning is still performed based on the first information, there is a high probability that the first device cannot be scanned. Therefore, the stored first information is deleted to ensure the validity of the information, avoid useless scanning, and save scanning time.

[0132] It should be noted that steps S502 and S503 are described by taking the process of receiving and storing the first information once as an example. In another embodiment, the second device updates and stores the first information each time it receives the first information.

[0133] Step S504: The second device scans on the first channel in response to an instruction to start the screen projection function.

[0134] For the second device, after receiving the first information, the second device can determine the first channel occupied by the first device. When the second device needs to project the screen, that is, the second device responds to the instruction to turn on the projection function, and scans on the first channel, thereby quickly scanning the first device. Among them, the instruction to turn on the projection function is used to indicate that the projection function has been turned on and needs to be connected to other devices for projection. When the second device turns on the projection function, the screen of the second device is displayed on the screen of the other device in real time.

[0135] In some embodiments, after the second device scans the first device on the first channel, the first device returns a scan reply frame to the second device, where the reply frame is used to indicate that the second device has scanned the first device.

[0136] Optionally, the second device performs a P2P (point-to-point wireless connection) scan on the first channel.

[0137] Step S505: The second device sends a connection request to the scanned first device.

[0138] The second device scans on the first channel and may scan the first device. After scanning the first device, the second device sends a connection request to the first device, where the connection request is used to request to establish a communication connection between the first device and the second device.

[0139] Step S506: The first device receives the connection request sent by the second device, and returns connection confirmation information to the second device in response to the connection request.

[0140] After receiving the connection request, if the first device determines that it can establish a communication connection with the second device, it returns confirmation connection information to the second device and establishes a communication connection with the second device. The confirmation connection information is used to indicate that the second device can establish a communication connection with the first device.

[0141] It should be noted that the embodiment of the present disclosure is explained by taking the example of the first device returning confirmation connection information to the second device. In another embodiment, if the first device cannot establish a communication connection with the second device, a rejection connection information is returned to the second device. The rejection connection information is used to indicate that the second device cannot establish a communication connection with the first device.

[0142] Step S507: When the second device receives the connection confirmation information returned by the first device, the second device establishes a communication connection with the first device.

[0143] When the second device receives the connection confirmation information returned by the first device, it determines that the first device can establish a communication connection with the second device, and therefore starts to establish a communication connection with the first device until the communication connection is established.

[0144] In some embodiments, a P2P connection is established between the first device and the second device.

[0145] It should be noted that after the first device establishes a communication connection with the second device, the first device and the second device perform screen projection, that is, the second device projects the displayed image to the screen of the first device in real time for display. The specific process of screen projection is not repeated here.

[0146] According to the method provided by the embodiment of the present disclosure, when a communication connection needs to be established between a first device and a second device, the first device sends first information by broadcasting based on the WiFi Aware protocol, the first information including information of a first channel occupied by the first device during communication, after receiving the first information, the second device scans the first device on the first channel and sends a connection request through the first channel, the first device receives the connection request, and thus a communication connection is established between the first device and the second device. Broadcasting the channel where the first device is located based on the WiFi Aware protocol is more applicable, and the second device directly scans on the channel where the first device is located without scanning on all channels, thereby shortening the scanning time and improving the speed of establishing a communication connection between the first device and the second device.

[0147] In addition, the second device stores the first information sent by the first device. When the second device needs to connect to other devices, it can obtain the first channel where the first device is located from the stored first information, thereby quickly scanning the first device on the first channel to improve the scanning speed.

[0148] Figure 6 is a flowchart of another device connection method according to an exemplary embodiment, which is executed by a first device and a second device. Figure 6 , the method comprises the following steps:

[0149] In step S601, in response to an instruction to start the screen projection function, the first device sends first information by broadcasting based on the WiFi Aware protocol. The first information includes information about the first channel occupied by the first device during communication and the SSID information of the first device.

[0150] The difference between step S601 and the above step S501 is that in step S601, the first information also includes SSID (Service Set Identifier) ​​information of the first device, and the SSID information is used to characterize the network to which the first device is connected. For example, the SSID is the name of the wireless hotspot to which the first device is connected.

[0151] Step S602: The second device enables a preset service based on the WiFi Aware protocol, and receives first information based on the preset service.

[0152] Step S603: the second device stores the first information.

[0153] The implementation of steps S602 and S603 refers to the above steps S502 and S503, which will not be described in detail here.

[0154] It should be noted that in step S603, when storing the first information, not only the information of the first channel occupied by the first device during communication is stored, but also the SSID information of the first device is stored. Optionally, after receiving the first information, the second device parses the first information, obtains the information of the first channel and the SSID information in the first information, and stores the information of the first channel and the SSID information.

[0155] Step S604: When there are multiple first devices, the second device responds to an instruction to start the screen projection function and selects SSID information that matches the preset SSID condition from the SSID information of multiple stored first devices.

[0156] In the disclosed embodiment, there are multiple first devices, and the multiple first devices respectively send first information by broadcasting based on the WiFi Aware protocol. In this case, the second device can receive the first information sent by the multiple first devices. When the second device detects an instruction to turn on the screen projection function, it can scan the first channel where each first device in the multiple first devices is located.

[0157] In order to reduce the number of channels to be scanned, at least one first channel is selected from multiple first channels for scanning using SSID information. Specifically, the second device is provided with a preset SSID condition, and SSID information matching the preset SSID condition is selected from the stored SSID information of multiple first devices. The preset SSID condition is used to characterize the SSID information of the device that the user expects to scan.

[0158] In some embodiments, the preset SSID condition includes preset information, and selecting SSID information matching the preset SSID condition from the stored SSID information of multiple first devices includes at least one of the following: selecting SSID information that is completely identical to the preset information from multiple SSID information of multiple first devices; selecting SSID information that is partially identical to the preset information from multiple SSID information of multiple first devices. For example, the preset information is a preset SSID, and the SSID information that is completely identical to the preset information means that the preset SSID is consistent with the SSID of the first device, and the SSID information that is partially identical to the preset information means that the preset SSID is partially identical to the SSID of the first device.

[0159] In some embodiments, a condition setting interface is displayed, and a preset SSID condition is set in the condition setting interface. For example, a condition setting area is displayed in the condition setting interface, and the user enters a preset SSID in the condition setting area as the preset SSID condition.

[0160] Step S605: The second device scans on the first channel where the first device corresponding to the selected SSID information is located.

[0161] The SSID information selected by the second device may be one or more. When the selected SSID information is one, scanning is performed on the first channel where the first device corresponding to the SSID information is located, and the scanned device is the first device corresponding to the SSID information; when multiple SSID information is selected, scanning is performed on the first information where the first devices corresponding to the multiple SSID information are located in sequence until the first device corresponding to any of the multiple SSID information is scanned.

[0162] Step S606: The second device sends a connection request to the scanned first device.

[0163] Step S607: The first device receives the connection request sent by the second device, and returns connection confirmation information to the second device in response to the connection request.

[0164] Step S608: When the second device receives the connection confirmation information returned by the first device, the second device establishes a communication connection with the first device.

[0165] The implementation of steps S606-S608 refers to the above steps S505-S507, which will not be repeated here.

[0166] It should be noted that in Figure 6 In the illustrated embodiment, only the example of a plurality of first devices is used for illustration. In another embodiment, even if the number of the first device is one, it is possible to determine whether the SSID information of the first device matches the preset SSID condition, that is, when the SSID information of the second device matches the preset SSID condition, the second device scans the first device on the first channel and sends a connection request through the first channel. When the SSID information of the second device does not match the preset SSID condition, the second device no longer performs scanning.

[0167] According to the method provided by the embodiment of the present disclosure, when a communication connection needs to be established between a first device and a second device, the first device sends first information by broadcasting based on the WiFi Aware protocol, the first information including information of a first channel occupied by the first device during communication, after receiving the first information, the second device scans the first device on the first channel and sends a connection request through the first channel, the first device receives the connection request, and thus a communication connection is established between the first device and the second device. Broadcasting the channel where the first device is located based on the WiFi Aware protocol is more applicable, and the second device directly scans on the channel where the first device is located without scanning on all channels, thereby shortening the scanning time and improving the speed of establishing a communication connection between the first device and the second device.

[0168] Furthermore, by setting a preset SSID condition, the second device can select a first device that meets the preset SSID condition from multiple first devices, thereby scanning on the channel where the first device that meets the preset SSID condition is located, reducing the number of scanned channels and further improving the scanning speed.

[0169] One thing that needs to be explained is that in the above embodiment, the first device is used as the screen projection device GO and the second device is used as the screen projection device GC. In another embodiment, the first device can be used as the screen projection device GC and the second device can be used as the screen projection device GO, that is, the first device can execute the steps executed by the above second device, and the second device can execute the steps executed by the above first device.

[0170] That is, the second device sends the second information by broadcasting based on the WiFi Aware protocol, and the second information includes the information of the second channel occupied by the second device during the communication process. The first device receives the first information, and in response to the quality of turning on the screen projection function, scans on the second channel and sends a connection request to the scanned second device. The second device receives the connection request sent by the first device, and the first device and the second device are connected in communication. For the specific implementation method, please refer to the above embodiment and will not be repeated here.

[0171] Figure 7 is a flowchart of another device connection method according to an exemplary embodiment, which is executed by the screen projection device GO and the screen projection device GC, see Figure 7 , the method comprises the following steps:

[0172] Step S701, the screen projection device GO regularly broadcasts the channel and SSID information of the screen projection device GO through WiFi Aware.

[0173] Among them, regular broadcasting is broadcasting according to a preset period.

[0174] Step S702, the screen projection device GC subscribes to the preset service through WiFi Aware and receives the broadcast message of the screen projection device GO.

[0175] The broadcast message is the above-mentioned first information.

[0176] Step S703, the screen projection device GC saves the channel and SSID information of the screen projection device GO.

[0177] Step S704, the screen projection device GC defines a second preset duration, regularly detects the saved channel and SSID information of the screen projection device GO, and removes the channel and SSID information that has not been updated for more than the second preset duration.

[0178] Step S705, the projection device GC saves the set preset SSID conditions.

[0179] Step S706: The projection device GC selects a matching channel from the saved channels and SSID information according to the preset SSID conditions, and initiates a P2P scan on the matching channel.

[0180] Step S707, the screen projection device GC receives the reply frame sent by the screen projection device GO, determines that the screen projection device GO is scanned, and then initiates a connection request and starts to establish a P2P connection. After the P2P connection is established, the screen projection is performed.
