To facilitate understanding of embodiments of the present application, some of the terms of embodiments of the present application are explained below to facilitate understanding by those skilled in the art.
1) Access point AP and station STA
The wireless local area network (wireless local area net, WLAN) mainly consists of Stations (STAs) and Access Points (APs). The STA device is an electronic device in the WLAN as an STA role, and the AP device is an electronic device in the WLAN as an AP role. In a WLAN, one or more STA devices may establish a wireless connection with an AP device through a built-in wireless network card or Wi-Fi module. The AP equipment can provide wireless connection service for the STA equipment, and a plurality of STA equipment can access the same Wi-Fi network through the AP equipment to realize interconnection. The AP device may be connected to the internet through a wire, so that the STA device may be connected to the internet through the AP device, for example, may download data from the internet side or upload data to the internet side, that is, the STA device may implement Wi-Fi internet service through the AP device.
In the embodiment of the present application, the STA device may be a notebook computer, or a desktop computer equipped with a wireless network card, i.e. a personal computer (personal computer, PC), or may be other electronic devices applying a Windows system, which is not limited in this application. The AP device may be a wireless router.
Illustratively, as shown in fig. 1 (a), the electronic device 1 and the electronic device 2 are STA devices, the wireless router 3 is an AP device, the electronic device 1 and the electronic device 2 respectively establish wireless connection with the wireless router 3 through Wi-Fi channels, and the wireless router 3 is connected to the network server 4 through wires. In this way, the electronic device 1 and the personal computer device 2 can implement the internet service through the wireless router 3, respectively. It should be noted that, in the present embodiment, the electronic device 1 and the electronic device 2 are connected to the same wireless router for illustration, and it is understood that, in actual implementation, the electronic device 1 and the electronic device 2 may be connected to different wireless routers, respectively, to implement the internet service.
For ease of illustration, a device that will support Wi-Fi wireless connectivity may be referred to below as a Wi-Fi device.
2) Wi-Fi P2P (peer-to-peer, end-to-end or Point-to-Point)
Wi-Fi P2P is a technical specification introduced by the Wi-Fi alliance, also called Wi-Fi Direct (Wi-Fi Direct), which supports multiple Wi-Fi devices in the absence of an AP to also form a point-to-point network (also called a P2P Group) and communicate with each other. For ease of illustration, wi-Fi devices supporting Wi-Fi P2P wireless connections may be referred to below as Wi-Fi P2P devices or P2P devices.
Two roles are defined in the P2P architecture, respectively:
(a) GO (group owner): AP roles in P2P networks.
(b) GC (group client): STA roles in P2P networks.
After P2P negotiation is completed among a plurality of P2P devices, one of the P2P devices acts as GO, i.e., AP role; other P2P devices act as GCs, i.e., STA roles. It should be noted that there can be only one GO in a P2P network, and one GO can support connections with one or more GCs.
Wi-Fi P2P connectivity may be applied in scenarios where large amounts of data are transmitted wirelessly between devices. For example, in actual implementation, wi-Fi P2P technology may be used for Wi-Fi screen display, for example, a smart phone supporting P2P may be directly connected to a smart television supporting P2P through Wi-Fi P2P technology, and then the smart phone transmits its screen display content to the smart television for display. Therefore, with the help of Wi-Fi P2P technology, the use scene of Wi-Fi technology is expanded by the direct connection between Wi-Fi devices.
3) Virtual AP (soft access point, softAP)
Virtual APs are also referred to as virtual hotspots or simulated hotspots. The virtual AP function can be realized on the electronic equipment by using special software through the wireless network card, and the wireless networking is realized. That is, the carrier in the WLAN is used as a wireless access point, and a computer, a mobile phone or other internet access device is connected to the carrier, and then the network of the carrier (e.g., 3G/4G/5G) is accessed.
In actual implementation, when a large amount of data needs to be transmitted between two electronic devices supporting P2P capability and applying Windows system in a wireless manner, the two electronic devices may be connected by a SoftAP-STA scheme: one electronic device can establish a softAP through a built-in wireless network card to serve as a wireless hotspot; another electronic device may be used as an STA, connected to the wireless hotspot, to implement Wi-Fi P2P connection between devices.
Exemplarily, as shown in (b) of fig. 1, assuming that the electronic device 1 and the electronic device 2 support Wi-Fi P2P, the electronic device 1 may create SoftAP as a wireless hotspot without connecting an AP; the electronic device 2 may be connected to the wireless hotspot, so that the electronic device 1 and the electronic device 2 may directly establish a connection and perform data interaction sharing, for example, may implement a multi-screen interaction function. By way of example, an image displayed on the screen of the electronic device 1 may be sent to the electronic device 2 for projection via a Wi-Fi P2P connection.
In some scenarios, a direct connection between multiple devices may be required through Wi-Fi P2P, while one or more of the multiple devices may also be required to communicate with the AP device through Wi-Fi connection. However, in the prior art, when one STA device tries to connect to another device through Wi-Fi P2P while there is communication with the AP device, the communication between the STA device and the AP device will be greatly affected.
Taking a specific scenario as an example, fig. 2 shows a schematic diagram of a Wi-Fi P2P application scenario according to an embodiment of the present application. As shown in fig. 2 (a), the electronic device 1 establishes a connection with the first AP based on the Wi-Fi protocol as an STA role; the electronic device 2, acting as STA, establishes a connection with the second AP based on Wi-Fi protocol. Wherein, the electronic device 1 and the electronic device 2 both apply Windows system and both support Wi-Fi P2P. Alternatively, the first AP and the second AP may be the same AP, or may be different APs, which is not limited in the embodiments of the present application.
As shown in fig. 2 (b), in the file sharing scenario implemented through the P2P connection, the electronic device 1 at the transmitting end creates a virtual AP, the electronic device 2 at the receiving end serves as an STA, and these two devices may establish Wi-Fi P2P data transmission channels. However, in the case where the electronic device 2 is connected to the second AP and is downloading a file from a network or playing a network video, if the electronic device 2 and the electronic device 1 establish a P2P connection to receive the file, the downloading of the network video or the file played on the electronic device 2 may be blocked, or even the electronic device 2 may be disconnected, for example, the electronic device 2 may display a prompt message: "device 1 sent a file to you, and your network connection will be temporarily interrupted in the transmission", which greatly affects the user's communication experience.
That is, a Windows system device (e.g., electronic device 2 described above) cannot support two STA roles simultaneously: one STA role is used to connect to a wireless hotspot (e.g., a second AP) to enable internet traffic, and the other STA role is used to connect to another device (e.g., electronic device 1 described above) to establish a Wi-Fi P2P connection.
In principle, when the electronic device 2 tries to establish a Wi-Fi P2P connection with the electronic device 1 while in communication with the AP, the electronic device 2 needs to perform a device discovery operation, such as scanning (scan), listening (listen), search (search), or the like, on a plurality of channels in order to discover (discover) the electronic device 1 and establish a connection therewith. When the electronic device 2 communicates with the second AP, the channel responsible for data communication with the second AP is in an operating state, and since the data communication and the device discovery operation cannot be performed simultaneously, if the electronic device 2 performs the scanning, listening or searching operation again at this time, the channel in communication with the AP cannot be operated at the time when the device discovery operation occurs, thereby affecting the communication between the electronic device 2 and the AP.
It should be noted that, here, the scenario description is performed on the premise that the electronic device does not support dual-frequency dual-transmission (dual band dual concurrent, DBDC). Specifically, while a STA device that does not support DBDC connects to an AP hotspot to surf the internet, if the STA device establishes a Wi-Fi P2P data transmission channel with other devices, the STA device may no longer connect to the hotspot to surf the internet, i.e., the internet surfing service may be interrupted.
In view of this, the embodiment of the present application provides a Wi-Fi P2P-based data transmission method, in a scenario where Wi-Fi direct connection is required between two electronic devices applying Windows systems to transmit data, a networked electronic device may create a virtual AP as a wireless hotspot, and another electronic device may connect to the wireless hotspot as an STA role, thereby establishing a Wi-Fi P2P channel between a transmitting device and a receiving device. The Wi-Fi P2P channel not only can transmit shared data, but also can transmit internet data, so that two-end equipment can still have internet surfing capability while transmitting data. Therefore, the problem that after the Wi-Fi P2P channel is established between two Windows system devices, the devices cannot be connected with a hot spot to surf the Internet is solved.
The execution body of the Wi-Fi P2P-based data transmission method provided in the embodiment of the present application may be the electronic device supporting Wi-Fi P2P and applying a Windows system, or may be a functional module and/or a functional entity capable of implementing the Wi-Fi P2P-based data transmission method in the electronic device, and the scheme of the present application may be implemented by means of hardware and/or software, and may specifically be determined according to actual use requirements.
First, a description will be given of a procedure of establishing Wi-Fi P2P connection between devices according to the embodiments of the present application in connection with a data interaction procedure between each module of the electronic device 1 and each module of the electronic device 2. Fig. 3 is a schematic diagram of a process of data interaction between each module in the electronic device 1 and each module in the electronic device 2.
As shown in fig. 3, the electronic device 1 may include: the device located in the application program layer cooperates with the APP, the first discovery connection module located in the system layer, the first Bluetooth chip and the first Wi-Fi chip located in the hardware layer. The electronic device 2 may include: a second discovery connection module and a co-service module (not shown) at the system level, a second bluetooth chip and a second Wi-Fi chip at the hardware level. As shown in fig. 3, the process of data interaction between the modules may include steps A1 to a16.
In step A1, the device cooperation APP in the electronic device 1 receives a sharing operation input by a user.
Illustratively, a control (e.g., a sharing control) for triggering inter-device connections and sharing files may be included in the interface of the device collaborative APP. For example, the sharing operation input by the user may be a series of operations in which the user triggers sharing after selecting a picture. For example, after a user selects a certain picture in the electronic device 1, the electronic device 1 may pop up an interface of the device collaborative APP, and when the user selects the sharing control, the electronic device 1 may scan to find surrounding connectable electronic devices, and display the scanned identifier of one or more electronic devices for the user to select; after the user selects one device identifier, the sharing operation can be completed.
And A2, the device cooperation APP sends a message to the first discovery connection module, and the message instructs the first discovery connection module to scan for nearby connectable devices.
After the device cooperation APP receives the sharing operation input by the user, the device cooperation APP sends an inter-process communication (inter-process communication, IPC) message to the first discovery connection module. The IPC message may carry a scan indication instruction, configured to instruct the first discovery connection module to invoke the capability scan of the first bluetooth chip to discover nearby connectable electronic devices.
And step A3, the first discovery connection module calls the Bluetooth capability scanning of the first Bluetooth chip to discover nearby connectable devices.
And after the first discovery connection module receives the IPC message, invoking the capability scanning of the first Bluetooth chip to discover nearby connectable electronic equipment.
In step A4, the electronic device 1 broadcasts the scanning signal through the first bluetooth chip.
In step A5, the electronic device 2 may receive the scan signal of the electronic device 1 through the second bluetooth chip and forward the scan signal to the second discovery connection module of the electronic device 2.
In step A6, the second discovery connection module of the electronic device 2 feeds back the basic information of the electronic device 2 itself to the first discovery connection module of the electronic device 1.
For example, the basic information of the electronic device 2 may include an internet protocol address (internet protocol address, IP address), a media access control address (media access control address, MAC address), a universal unique identification code (universally unique identifier, uuid), a device identification, a device name, and the like of the electronic device 2.
When the first discovery connection module of the electronic device 1 scans the connectable electronic device 2, the first discovery connection module may acquire basic information of the electronic device 2.
In step A7, the first discovery connection module sends the discovered basic information (such as the device name and MAC address) of the connectable electronic device to the device cooperation APP.
In step A8, the device cooperation APP displays the basic information of the connectable one or more electronic devices discovered by scanning in a connectable device list for display to a user for viewing.
In some embodiments, the connectable device list displayed by the device cooperation APP includes all devices, such as a tablet large screen, a mobile phone, or a wearable device, near the electronic device 1, for which bluetooth functions are turned on.
In other embodiments, after receiving the information of all the devices with the bluetooth function turned on, the device cooperation APP may screen out the devices supporting Wi-Fi P2P for display, for example, if the wearable device does not support Wi-Fi P2P, the device cooperation APP does not display the wearable device in the connectable device list.
In particular to the solution of the present application, the connectable one or more electronic devices found by the device in cooperation with APP scanning include the electronic device 2.
In step A9, when the user clicks the electronic device 2 in the connectable device list, the device cooperation APP may receive the clicking operation of the user.
And A10, the device cooperates with the APP to send an IPC message to the first discovery connection module, and the IPC message is used for indicating the first discovery connection module to call the first Bluetooth chip to establish Bluetooth connection with the electronic device 2.
The IPC message may carry basic information of the electronic device 2.
The bluetooth connection may be established by using a bluetooth low energy (bluetooh low energy, BLE) technology, or may be established by using other bluetooth technologies.
And step A11, after the first discovery connection module receives the IPC message, the capability of the first Bluetooth chip can be called to carry out Bluetooth connection with the second Bluetooth chip of the electronic equipment 2 so as to realize communication connection between the electronic equipment 1 and the electronic equipment 2.
Step a12, the bluetooth connection is successfully established between the electronic device 1 and the electronic device 2.
In step a13, the electronic device 1 negotiates to establish a P2P connection with the electronic device 2 based on the bluetooth connection.
The electronic device 1 and the electronic device 2 may interact with each other in the network connection based on the bluetooth connection. For example, the electronic device 2 may send a message to the electronic device 1 indicating that the electronic device 2 is networked or not networked.
In the embodiment of the present application, when negotiating to establish a P2P connection, different scenarios may correspond to different schemes or policies:
(1) A scenario in which both the electronic device 1 on the transmitting side and the electronic device 2 on the receiving side are networked.
Scheme one: the electronic equipment 1 creates a virtual AP as a wireless hotspot, the electronic equipment 2 at the receiving end serves as an STA role and is connected to the wireless hotspot, so that P2P connection can be successfully established between the electronic equipment 1 and the electronic equipment 2, data can be directly transmitted, the Internet surfing service of the electronic equipment 1 is not affected, and the electronic equipment 2 can realize the Internet surfing service through the wireless hotspot corresponding to the electronic equipment 1.
In the second scheme, the electronic device 2 creates a virtual AP as a wireless hotspot, the electronic device 1 at the receiving end takes a role of STA and connects to the wireless hotspot, so that a P2P connection can be successfully established between the electronic device 1 and the electronic device 2, data can be directly transmitted, the internet service of the electronic device 2 is not affected, and the electronic device 1 can realize the internet service through the wireless hotspot corresponding to the electronic device 2.
Alternatively, when the electronic device 1 of the transmitting end is networked, the virtual AP may be created by default by the transmitting end device without taking account of the networking situation of the electronic device 2 of the receiving end.
(2) The electronic equipment 1 at the transmitting end is not networked, and the electronic equipment 2 at the receiving end is networked.
The electronic equipment 2 creates a virtual AP as a wireless hotspot, the electronic equipment 1 takes a role of an STA and is connected to the wireless hotspot, so that P2P connection can be successfully established between the electronic equipment 1 and the electronic equipment 2, data can be directly transmitted, the Internet surfing service of the electronic equipment 2 is not affected, and the electronic equipment 1 can realize the Internet surfing service through the wireless hotspot corresponding to the electronic equipment 2.
(3) A scenario in which the electronic device 1 on the transmitting side is networked and the electronic device 2 on the receiving side is not networked.
The electronic equipment 1 creates a virtual AP as a wireless hotspot, the electronic equipment 2 takes a STA role and is connected to the wireless hotspot, so that P2P connection can be successfully established between the electronic equipment 1 and the electronic equipment 2, data can be directly transmitted, the Internet surfing service of the electronic equipment 1 is not affected, and the electronic equipment 2 can realize the Internet surfing service through the wireless hotspot corresponding to the electronic equipment 1.
(4) Neither the electronic device 1 at the transmitting end nor the electronic device 2 at the receiving end is networked.
Either of the electronic device 1 and the electronic device 2 may create a wireless hotspot to enable an inter-device P2P connection. For example, the electronic device 1 creates a virtual AP as a wireless hotspot, and the electronic device 2 acts as an STA and connects to the wireless hotspot, so that a P2P connection can be successfully established between the electronic device 1 and the electronic device 2, and data can be directly transmitted.
In the following, a scheme one of the (1) th scenario is taken as an example for illustration, and the scheme one correspondingly executes a14-a23 described below; scheme two of scenario (1) is similar to scheme one and will not be described again here. Then, the scheme A24-A32 corresponding to the (2) scene is taken as an exemplary illustration; the scheme corresponding to the (3) th scene is similar to the scheme corresponding to the (2) th scene, and will not be repeated here. The above-mentioned scenario (4) is not the focus of this case, and thus the processing procedure thereof is not shown in the flowchart.
In step a14, the first discovery connection module of the electronic device 1 invokes the first Wi-Fi chip to create a virtual AP.
Wherein the virtual AP has a service set identification (service set identifier, SSID) and a password.
Step a15, the first discovery connection module sends the SSID and the password to the second discovery connection module of the electronic device 2 through the established bluetooth connection.
Step A16, the second discovery connection module of the electronic device 2 invokes the second Wi-Fi chip to establish Wi-Fi P2P connection with the electronic device 1 according to the received SSID and password.
In step a17, the electronic device 2 connects to the virtual AP corresponding to the electronic device 1. If the electronic device 2 is networked through the second AP, the second Wi-Fi chip of the electronic device 2 disconnects from the second AP.
Step a18, a Wi-Fi P2P channel is successfully established between the electronic device 1 and the electronic device 2.
The Wi-Fi P2P channel is a physical channel for carrying data transmission.
In step a19, a Socket channel is established between the electronic device 1 and the electronic device 2.
The Socket channel is a logic channel established based on a Wi-Fi P2P channel.
In practical applications, the Socket channel is used for implementing data transmission based on IP of the two end devices or modules, a certain defined port, and agreement of protocols (such as TCP/IP, UDP, SMTP, FTP) supported by the two end devices.
The service module of the electronic device can create one or more Socket channels according to the current service condition to respectively transmit data of different services. Specifically, in this application, the current service may include a transmission service for sharing data and a transmission service for surfing the internet, based on which the electronic device 1 may create two Socket channels, which are respectively referred to as a Socket channel 1 and a Socket channel 2.Socket channel 1 can be used for transmitting shared data, and Socket channel 2 can be used for transmitting internet data.
In step a20, data is shared between the electronic device 1 and the electronic device 2 through the Socket channel 1.
In step a21, internet data of the electronic device 2 is transmitted between the electronic device 1 and the electronic device 2 through the Socket channel 2.
Thus, the electronic device 1 and the electronic device 2 can realize data sharing and internet surfing services through the P2P channel.
In step a22, after the sharing is completed, the electronic device 1 deletes the virtual AP.
Here, in response to the user trigger operation, the electronic apparatus 1 may delete the virtual AP; the electronic device 1 may automatically delete the virtual AP after the sharing is completed.
In step a23, the electronic device 2 disconnects from the virtual AP and automatically selects a usable hotspot, e.g. the electronic device 2 automatically connects to the originally connected second AP.
As can be seen from the above a14-a23, in the case of networking the electronic device 1, the electronic device 1 creates a virtual AP as a wireless hotspot; the electronic equipment 2 is used as an STA role and is connected to the virtual AP created by the electronic equipment 1, so that a P2P channel and a Socket channel are established between the equipment, and the purposes of data sharing and internet surfing are realized.
The following description will be further made with reference to a24-a32 below to further explain an implementation manner of establishing a P2P channel between devices when the electronic device 1 at the transmitting end is not networked and the electronic device 2 at the receiving end is networked.
In step a24, the second discovery connection module of the electronic device 2 invokes the second Wi-Fi chip to create a virtual AP.
Also, the virtual AP has a service set identification (service set identifier, SSID) and a password.
In step a25, the second discovery connection module sends the SSID and the password to the first discovery connection module of the electronic device 1 through the established bluetooth connection.
In step a26, the first discovery connection module of the electronic device 1 invokes the first Wi-Fi chip to establish Wi-Fi P2P connection with the electronic device 2 according to the received SSID and password.
Wherein the electronic device 1 is connected to a virtual AP corresponding to the electronic device 2.
Step a27, a Wi-Fi P2P connection is successfully established between the electronic device 1 and the electronic device 2.
In step a28, a Socket channel is established between the electronic device 1 and the electronic device 2.
Similarly, two Socket channels are established between the electronic device 1 and the electronic device 2, and are respectively called a Socket channel 1 and a Socket channel 2.Socket channel 1 can be used for transmitting shared data, and Socket channel 2 can be used for transmitting internet data.
In step a29, data is shared between the electronic device 1 and the electronic device 2 through the Socket channel 1.
In step a30, internet data of the electronic device 1 is transmitted between the electronic device 1 and the electronic device 2 through the Socket channel 2.
Thus, the electronic device 1 and the electronic device 2 can realize data sharing and internet surfing services based on Wi-Fi P2P channels.
In step a31, after the sharing is completed, the electronic device 1 disconnects from the virtual AP.
The electronic device 1 may automatically select a usable hotspot, e.g. the electronic device 1 may automatically connect to an originally connected AP.
In step a32, the electronic device 2 deletes the virtual AP.
Here, in response to the user trigger operation, the electronic apparatus 1 may delete the virtual AP; the electronic device 1 may automatically delete the virtual AP after the sharing is completed.
As can be seen from the above a24-a32, when the electronic device 1 at the transmitting end is not networked, and the electronic device 2 at the receiving end is networked, the electronic device 2 creates a virtual AP as a wireless hotspot; the electronic equipment 1 is used as an STA role and is connected to a virtual AP created by the electronic equipment 2, so that a P2P channel and a Socket channel are established between the equipment, and the purposes of data sharing and internet surfing are realized.
The Wi-Fi P2P-based data transmission method provided by the embodiments of the present application is exemplarily described below with reference to the accompanying drawings. For convenience of explanation, the electronic apparatus 1 of the transmitting side may be hereinafter referred to as a transmitting side apparatus, and the electronic apparatus 2 of the receiving side may be referred to as a receiving side apparatus.
First embodiment
The first embodiment mainly describes how data transmission is performed between the sending end device and the receiving end device through Wi-Fi P2P and how the purpose of uninterrupted internet service of the networked device is achieved in a scene that both the sending end device and the receiving end device are networked.
Fig. 4 is a flowchart of a Wi-Fi P2P-based data transmission method according to a first embodiment of the present application. Referring to fig. 4, the method 100 includes steps S101-S105 described below.
S101, the electronic device 1 receives a first operation of a user, where the first operation is used to trigger the electronic device 1 to send first data to the electronic device 2 in a P2P transmission manner.
The electronic device 1 and the electronic device 2 are devices applying a Windows system. Both the electronic device 1 and the electronic device 2 support Wi-Fi P2P protocols, and the P2P functions of the electronic device 1 and the electronic device 2 are turned on by default. The P2P function may also be referred to as a mutual transmission or sharing function, which is not limited in the embodiments of the present application.
Alternatively, the first operation may include a plurality of sub-operations. For example, the first operation includes a first sub-operation, a second sub-operation, a third sub-operation, and a fourth sub-operation described below. Illustratively, as shown in fig. 5, when a user needs to share a picture 40 (i.e., first data) on the electronic device 1 to the electronic device 2, the user may select the picture 40 (first sub-operation) of the electronic device 1, and when the menu bar 41 is popped up, the user may click on a "share" control (second sub-operation) in the menu bar 41, and then the electronic device 1 may automatically scan to find surrounding connectable devices. After the electronic device 1 discovers the electronic device 2, the electronic device 1 displays an identification 42 of the electronic device 2. In response to an operation (third sub-operation) in which the user selects the identification 42 of the electronic device 2, the electronic device 1 may display a prompt window 43 for prompting the user to confirm whether to send the picture 40 to the electronic device 2. In response to the user clicking on the send control in the prompt window 43 (fourth sub-operation), the electronic device 1 may send a message to the electronic device 2 to share the picture. As shown in fig. 4, the electronic device 2 may display a message prompt box 44 for sharing the picture, where the message prompt box 44 is used to prompt: the device 1 shares a picture with you, refuses or accepts it. It will be appreciated that the first operation corresponds to the sharing operation described above in fig. 3.
Alternatively, the Wi-Fi P2P function of the electronic device 1 may be triggered by a user to start, or may be automatically started when the electronic device 1 is started, or may be triggered to start under a specific condition, which is not limited in the embodiments of the present application.
In the first embodiment, as described above, when the electronic device 1 receives the first operation of the user, the electronic device 1 first discovers the electronic device 2 by broadcasting, scanning, or the like, and then the electronic device 1 may directly initiate establishment of the P2P channel with the electronic device 2 in the case of having been networked. Specifically, the electronic device 1 creates a virtual AP as a wireless hotspot; the electronic device 2 acts as an STA and connects to the virtual AP created by the electronic device 1, so as to establish a P2P channel between the devices. That is, in the case where the transmitting end device is networked, the virtual AP may be created by default by the transmitting end device as a wireless hotspot without knowing the networking condition of the receiving end device and without negotiating with the receiving end device which end device to create the virtual AP.
In other embodiments, when the electronic device 1 receives the first operation of the user, the electronic device 1 and the electronic device 2 may first establish a bluetooth connection channel, then perform information interaction through the bluetooth connection channel, and negotiate to establish a P2P channel between the devices. For example, one of the electronic device 1 and the electronic device 2 may be determined to be a virtual AP role according to the networking situation of both parties. Alternatively, the electronic device 1 and the electronic device 2 may negotiate that the networked one-end device creates a virtual AP as a wireless hotspot.
If the electronic device 1 is connected to the first AP and the electronic device 2 is connected to the second AP, that is, the sending device and the receiving device are both networked. In this case, the transmitting end may create a virtual AP as a wireless hotspot; alternatively, the receiving end may create a virtual AP as the wireless hotspot. Alternatively, the electronic device 1 and the electronic device 2 may negotiate the creation of the virtual AP by the sender. For convenience of explanation, fig. 3 illustrates an example in which the electronic device 1 at the transmitting end creates a virtual AP. Alternatively, the first AP and the second AP may be the same AP, or may be different APs, which is not limited in the embodiment of the present application.

Referring to fig. 5 again, in the case where the transmitting device creates a virtual AP, when the electronic device 1 sends the picture 40 to the electronic device 2, the prompt window 43 popped up by the electronic device 1 prompts: the other party in transmission will be connected to the local network; the message prompt box 44 of the reality of the electronic device 2 prompts: the transmitting host will connect to the counterpart network.
S103, the electronic device 1 and the electronic device 2 establish a P2P channel based on the virtual AP.
In the embodiment of the present application, the electronic device 1 as the transmitting end creates a virtual AP as a wireless hotspot. Further, the electronic device 2, acting as STA, may connect to a virtual AP created by the electronic device 1. It will be appreciated that in the case where the electronic device 2 is connected to the virtual AP created by the electronic device 1, the electronic device 1 and the electronic device 2 successfully establish the P2P channel.
S104, the electronic equipment 1 sends the first data to the electronic equipment 2 through the P2P channel, and transmits the Internet surfing data of the electronic equipment 2.
It will be appreciated that data may be transferred directly between the electronic device 1 and the electronic device 2 via the P2P channel, and no data may be transferred indirectly via the server.
In the embodiment of the present application, the P2P channel established between the electronic device 1 and the electronic device 2 is one physical channel, which may be used as two logical channels in a specific application: one of the logic channels is used for transmitting first data to be shared, and the channel can be called a sharing channel; another logical channel is used to transmit the internet data of the electronic device 2, which may be referred to as an internet data channel.
S105, the electronic device 1 transmits the internet data of the electronic device 1 and the internet data of the electronic device 2 through the first AP and the network side.
The electronic device 1 not only can be used as an STA role, but also can interact with a network side through a first AP; moreover, the electronic device 1 can also be used as a virtual AP role, and establish a P2P channel with the electronic device 2 used as an STA role and perform data transmission; and, the electronic device 1 may also provide internet surfing capabilities for the electronic device 2 in case the electronic device 1 is networked.

In this case, the P2P channel established between the electronic device 1 and the electronic device 2 may be used as two logical channels: one of the logical channels, the shared channel, is used for data transmission (e.g., transmitting first data); the other logical channel, i.e. the internet data channel, is used for transmitting internet data of the electronic device 2.
On the other hand, in response to a user disabling networking operations on the electronic device 2, the electronic device 2 may not surf the internet through the wireless hotspot. In this case, the P2P channel established between the electronic device 1 and the electronic device 2 may be used as a sharing channel only for data interchange.

In some embodiments, the electronic device 2 may display networking prompt information, where the networking prompt information is used to prompt the electronic device 2 to implement surfing the internet through a wireless hotspot corresponding to the electronic device 1.
In some embodiments, the networking prompt information may include an option to confirm networking and an option to prohibit networking for selection by the user.
In one aspect, the electronic device 2 may be networked through the wireless hotspot in response to an acknowledge networking operation by the user on the electronic device 2. In this case, the P2P channel established between the electronic device 1 and the electronic device 2 may be used as two logical channels in a specific application: one of the logic channels is a network access data channel, which is used for transmitting network access data of the electronic equipment 2; the other logical channel, the shared channel, is used only for transmitting the first data.
On the other hand, in response to a user disabling networking operations on the electronic device 2, the electronic device 2 may not surf the internet through the wireless hotspot. In this case, the P2P channel established between the electronic device 1 and the electronic device 2, i.e., the sharing channel, is only used for transmitting the first data.
Steps S202A-S205A above describe that in the case where the sending device is networked, the sending device may create a virtual AP as a wireless hotspot, and then the receiving device connects to the wireless hotspot, so that a P2P channel is successfully established between the devices, and end-to-end data transmission is achieved. An implementation of how the P2P channel is established in case the receiving end device is networked will be described below in connection with steps S202B-S205B.

S203B, the electronic device 1 and the electronic device 2 establish a P2P channel based on the virtual AP.
It will be appreciated that the electronic device 1 is not networked and the electronic device 2 is connected to the second AP, which means that only the electronic device 2 of the electronic device 1 and the electronic device 2 is networked, that is, only the receiving end device of the transmitting end device and the receiving end device is networked.
In this embodiment of the present application, when the electronic device 1 receives the first operation of the user, the electronic device 1 and the electronic device 2 may first establish a bluetooth connection channel, and then perform information interaction based on the bluetooth connection channel, and negotiate that a virtual AP is created by a networked end device as a wireless hotspot. In particular to the second embodiment, since the electronic device 2 as the receiving end has been networked, the electronic device 2 can create a virtual AP as a wireless hotspot.
Illustratively, when the electronic device 1 receives the first operation of the user, the electronic device 1 first discovers the electronic device 2 through bluetooth technology, and then the electronic device 1 negotiates with the electronic device 2 to establish the P2P channel. Wherein the electronic device 2 is networked, the electronic device 2 can create a virtual AP as a wireless hotspot; the electronic device 1, acting as STA, connects to the virtual AP created by the electronic device 2. It will be appreciated that in the case where the electronic device 1 is connected to the virtual AP created by the electronic device 2, the electronic device 1 and the electronic device 2 successfully establish the P2P channel.

In some embodiments, the electronic device 1 may display networking prompt information, where the networking prompt information is used to prompt the electronic device 1 to implement surfing through a wireless hotspot corresponding to the electronic device 2.
In some embodiments, the networking prompt information may include an option to confirm networking and an option to prohibit networking for selection by the user.
In one aspect, in response to an acknowledge networking operation by a user on the electronic device 1, the electronic device 1 may be networked through a corresponding wireless hotspot of the electronic device 2. In this case, the P2P channel established between the electronic device 1 and the electronic device 2 may be used as two logical channels in a specific application: one of the logic channels is a network access data channel, which is used for transmitting network access data of the electronic equipment 2; the other logical channel, the shared channel, is used for transmitting the first data.
On the other hand, in response to a user's networking prohibition operation on the electronic device 1, the electronic device 1 may not be networked through the wireless hotspot corresponding to the electronic device 2. In this case, the P2P channel established between the electronic device 1 and the electronic device 2, i.e., the sharing channel, is only used for transmitting the first data.
As can be seen from the steps S202B-S205B, in the case that the receiving end device is networked, the receiving end device may create a virtual AP as a wireless hotspot, and then the transmitting end device connects to the wireless hotspot, so that a P2P channel is successfully established between the devices, and end-to-end data transmission is achieved.

The electronic device 2 at the receiving end may be connected to the SoftAP created by the electronic device 1 as an STA role, so that the electronic device 1 and the electronic device 2 establish a P2P channel (including a sharing data channel and a surfing data channel).
As shown in fig. 11 (a) and (b), the first Wi-Fi network of the transmitting end is still reserved, and a fifth Wi-Fi network is newly established between the transmitting end device and the receiving end device.

The electronic device 1 at the transmitting end may be connected to the SoftAP created by the electronic device 2 as an STA role, so that the electronic device 1 and the electronic device 2 establish a P2P channel (including a sharing data channel and a surfing data channel).
As shown in fig. 12 (a) and (b), the second Wi-Fi network of the receiving end is still reserved, and a sixth Wi-Fi network is newly established between the transmitting end device and the receiving end device. Based on the newly-built sixth Wi-Fi network, data sharing can be performed between the sending end device and the receiving end device, internet surfing data of the sending end device can be transmitted, wherein the internet surfing data of the sending end device can be sent to the receiving end device through an internet surfing data channel, and further interaction with the internet side is performed through the second AP.

When the user triggers the electronic device 1 to share data with the electronic device 2 in the P2P manner, the electronic device 1 at the transmitting end may negotiate with the electronic device 2 at the receiving end about establishing a P2P channel.
As shown in fig. 14 (b), a virtual AP (i.e., softAP) may be created by the electronic device 1 of the transmitting end as a wireless hotspot. The electronic device 2 at the receiving end may be connected to the SoftAP created by the electronic device 1 as an STA role, so that the electronic device 1 and the electronic device 2 establish a P2P channel (including a shared data channel). A seventh Wi-Fi network is newly established between the transmitting end device and the receiving end device. Based on the newly-built seventh Wi-Fi network, data sharing can be performed between the sending end device and the receiving end device.
Alternatively, as shown in fig. 14 (c), a virtual AP (i.e., softAP) may be created by the electronic device 2 at the receiving end as a wireless hotspot. The electronic device 1 at the transmitting end may be connected to the SoftAP created by the electronic device 2 as an STA role, so that the electronic device 1 and the electronic device 2 establish a P2P channel (including a shared data channel). An eighth Wi-Fi network is newly established between the sending end device and the receiving end device. Based on the newly-built eighth Wi-Fi network, data sharing can be performed between the sending terminal equipment and the receiving terminal equipment.
In the embodiment of the application, under the condition that the sending end equipment and the receiving end equipment are not networked, any one of the sending end equipment and the receiving end equipment can be used for creating a virtual AP as a wireless hot spot, so that the sending end equipment and the receiving end equipment can establish a P2P channel based on the wireless hot spot, and data sharing can be realized through the P2P channel, and therefore equipment interaction experience can be improved.
In summary, the above three embodiments take three application scenarios as examples, and the Wi-Fi P2P-based data transmission method provided in the embodiments of the present application is illustrated.
Scene one: under the condition that a sending end and a receiving end are respectively connected with an AP to surf the internet, if the sending end and the receiving end need Wi-Fi direct communication channels to exchange personal data, the sending end establishes a Wi-Fi channel in a software-by-AP role and the receiving end establishes a STA role, so that the sending end can provide the receiving end with surfing capability; or the receiving end establishes a Wi-Fi channel in a SoftAP role and the sending end establishes a Wi-Fi channel in an STA role, so that the receiving end can provide internet surfing capability for the sending end. Therefore, the shared data can be transmitted on the same P2P channel, and both end devices can be ensured to be on the Internet.
Scene II: under the condition that only one end of the sending end and the receiving end is accessed to the network, one end of the access network has a softAP role, one end of the non-access network has an STA role, and the sending end and the receiving end can only share file data on an established Wi-Fi P2P channel. Meanwhile, the established P2P channel does not influence the Internet surfing state of the equipment at one end of the accessed network.
Scene III: under the condition that the sending end and the receiving end are not connected with a network, the receiving end takes a STA role and the sending end takes a softAP role, or the sending end takes the STA role and the receiving end takes the softAP role, and the sending end and the receiving end can only share file data on an established Wi-Fi P2P channel.
According to the embodiment of the application, on a Wi-Fi P2P channel where the two receiving and transmitting sides transmit shared data, one device can use a hot spot of the other device, and the device can still have the internet surfing capability while transmitting the data. Therefore, the problem that when a large amount of data is transmitted between two Windows system devices in a wireless mode, after a Wi-Fi P2P channel is established, the devices cannot be connected with a hot spot to surf the Internet is solved.
In some embodiments, for cross-device wireless data transmission in which connection cannot be established by using a Wi-Fi P2P GO-GC mode, and each device also has a scene of connecting an AP hotspot internet surfing requirement, a scheme provided by the embodiments of the present application may also be used, where a sending end and a receiving end may share file data and share internet surfing capability on an established Wi-Fi P2P channel.
