The Wi-Fi P2P connection protocol is generally implemented in the Wi-Fi chip, and the FRAMEWORK layer in the terminal device interacts with the chip through the driver. For example, taking AOSP as an example, the FRAMEWORK layer is used to interact with the driver and support encryption authentication through wpa_supplicant. The application layer provides several interface functions that can be directly called by developers/businesses. After calling, the chip can execute the corresponding Wi-Fi function through the driver. -Fi P2P related operations, the FRAMEWORK layer itself is responsible for the message transfer and coordination, connection management, etc. between the upper-layer application and the lower-layer hardware (including wpa_supplicant, Wi-Fi Driver, Chipset). At present, the user's operation of Wi-Fi P2P is realized by the application layer by calling the Wi-Fi P2P related interfaces and services in FRAMEWORK.

A complete Wi-Fi P2P service includes three stages: Wi-Fi P2P device discovery, Wi-Fi P2P device connection, and Wi-Fi P2P device service data transmission. A P2P group (or also called a Wi-Fi P2P group) is formed after the Wi-Fi P2P device connection is established. In a P2P group, the device has two roles: P2P group manager (group owner, GO) and P2P group client (group client, GC). In order to explain and limit, there are mainly the following three points:

(1) GO devices can only be connected to GC, and cannot establish connections with other GO devices;

(2) GC devices can only be connected with GO devices, and cannot establish connections with other GO devices or GC devices;

(3) There is an upper limit on the number of GO devices connected to GC devices;

In addition to the limitations of the Wi-Fi DIRECT protocol itself, different chip manufacturers and different operating systems (such as Android, Windows, etc.) also have some other limitations on Wi-Fi P2P connections. For example, chip platforms such as HiSilicon do not support the same Multiple P2P roles on the device. Not supporting multiple P2P roles on the same device can be understood as: the same device cannot act as GO and GC at the same time; or, during the period when one device acts as a GO, the device cannot act as a GO in another P2P group; or , while a device is serving as a GC, the device cannot serve as a GC in another P2P group. Moreover, AOSP does not support the coexistence of multiple P2P roles on the same device. Therefore, as shown in Figure 2, the current form of Wi-Fi P2P device connection and networking is limited to a star network centered on GO devices.

In the standard Wi-Fi DIRECT protocol specification, a total of 4 steps are required to establish a Wi-Fi P2P device connection, namely: Wi-Fi P2P device discovery (Device Discovery), group negotiation (Group Formation), Wi-Fi protection Setup (Wi-Fi protected setup, WPS) process, and associated connections.

Among them, Wi-Fi P2P device discovery is a key capability in Wi-Fi DIRECT, including two stages: scan and find. The Scan phase is to discover existing GO devices. The find phase is divided into a listening phase (listen State) and a search phase (search State). P2P devices will switch back and forth between the Search phase and the Listen phase. In the Search phase, the P2P device will send a probe request frame (Probe Request), and in the Listen phase, the P2P device will receive the probe request frame (Probe Request) from other devices and reply with a probe reply frame (Probe Response). For the Search stage and the Listen stage, only if the P2P devices are in different stages, it is possible to discover each other and carry out the subsequent process. Therefore, the protocol stipulates that the duration of these two phases is random, to ensure that there can be a window where the two phases are wrong, that is, there is no temporal overlap between the two phases, and there needs to be a time interval between the two phases.

Group negotiation is the next stage after Wi-Fi P2P devices are discovered. Due to the protocol, on a Wi-Fi P2P connection, two-end devices have GO and GC roles, so they need to negotiate their roles before connecting.

The WPS process is the next step after group negotiation, which is used to ensure the security and reliability of the established connection and avoid security loopholes such as identity spoofing.

The final association connection involves a 4-step handshake, after which a trusted Wi-Fi P2P connection is established between the two devices.

To establish a Wi-Fi P2P device connection according to the standard Wi-Fi DIRECT protocol, you only need to trigger Wi-Fi P2P discovery at both ends, and then wait for the discovery result. When the desired device is scanned, initiate a connection and wait for the connection result. . However, using this technology will cause the Wi-Fi P2P device connection process to take a long time. As described above, the two-end device needs to have a wrong window between the Search stage and the Listen stage (that is, the device at one end is in the Search stage, and the device at the other end needs to In the Listen stage. Or the device at one end is in the Listen stage, and the device at the other end needs to be in the Search stage). For either end device, it will switch back and forth between the Search stage and the Listen stage. When one end of the device is in the Search stage, the other end of the device cannot be guaranteed to be in the Listen stage, and when one end of the device is in the Search stage and the other end of the device is not in the Listen stage, device discovery cannot be performed. In this case , when one end device switches from the Search stage to the Listen stage, if the other end device also switches to the Search stage, the two-end device can perform device discovery, and if the other end device is still in the Listen stage, the two-end device cannot perform device discovery . In other words, during this process, both devices switch between the Search stage and the Listen stage. Only one end of the device is in the Listen stage, and the other end of the device is in the Search stage at the same time to discover the device, but this process may require Both devices at both ends switch between the Search phase and the Listen phase multiple times to meet the conditions for device discovery: that is, the device at one end needs to be in the Search phase and the device at the other end is in the Listen phase at the same time, or the device at one end is in the Listen phase. The device at the other end is in the Search phase at the same time. The process of meeting the conditions for discovering devices takes a long time, and the typical value ranges from 1 to 3 seconds. The connection time is also long, with a typical value of 2 to 3 seconds. In general, a complete Wi-Fi P2P connection process takes 3 to 6 seconds, and the user experience is poor.

In order to speed up the establishment process of the Wi-Fi P2P connection, the standard Wi-Fi P2P connection establishment process has been modified and optimized in the related art. Use bluetooth low energy (BLE) discovery instead of Wi-Fi P2P device discovery to speed up the discovery process. After BLE discovers the device, it uses the service to directly specify the GO/GC role to simplify the group negotiation process. By establishing a BLE/Bluetooth basic rate (BR) connection, performing security authentication and exchanging P2P group information based on the BLE/BR connection, the GC device is finally directly connected to the P2P group on the designated channel to realize Wi- Fi P2P connection. Using this technology can accelerate the process of establishing a Wi-Fi P2P connection, but it is strongly dependent on BLE/BR connection. This process is basically customized by the business and does not have universality and scalability.

In view of this, this application provides a method for establishing a Wi-Fi P2P connection. When performing Wi-Fi P2P device discovery, various discovery methods (such as BLE discovery, LAN discovery, Wi-Fi P2P discovery, broadcast Discovery, etc.) for device discovery, it can support multiple discovery methods, and at the same time support the use of different types of connection methods or broadcast methods for information interaction, which improves the versatility and scalability. In addition, the information required for the Wi-Fi P2P connection is exchanged in stages, and the inherent information in the information required for the Wi-Fi P2P connection (for example, the list of channels supported by the device, the service set identifier of the P2P group) is exchanged. , SSID), password (password, PWD), whether to support broadband (for example, whether to support 160MHz), device information, etc.) are exchanged in advance before the Wi-Fi P2P service is initiated. Change the variable information in the information required for Wi-Fi P2P connection (for example: Wi-Fi P2P connection status of the device, role, frequency of the AP (ie Wi-Fi hotspot) connected to the device, etc.) after the variable information changes , to synchronize between devices, so that when the user uses the device to actually initiate a Wi-Fi P2P connection, most of the information has been exchanged, and only some simple signaling (such as broadcast messages, Bluetooth messages, etc.) needs to be sent. Send signaling) to complete the Wi-Fi P2P connection, thereby further shortening the time-consuming of the Wi-Fi P2P connection and improving the user experience.

For example, the list of channels supported by a smartphone refers to the list of channels supported by a smartphone on the 5GHz frequency band, which is an inherent property of a smartphone. SSID and PWD refer to the network ID and key used by the smartphone when creating a P2P group. These two items are randomly generated when the smartphone is powered on, and remain unchanged for a certain period of time (ie, the life cycle). After the cycle, it will be randomly generated again to ensure the security of the Wi-Fi P2P connection.

Or, as another possible implementation manner, in S210, the communication module in the smartphone can also send the Wi-Fi P2P connection of the smartphone to the communication module of the large-screen device through broadcasting and the first connection. inherent information in .

After the communication module of the large-screen device receives the inherent information in the information required by the Wi-Fi P2P connection of the smartphone through the first connection and/or broadcasting, it can store the information required by the Wi-Fi P2P connection of the smartphone. inherent information.

S215, the communication module in the large-screen device transmits the inherent information in the information required by the Wi-Fi P2P connection of the large-screen device (that is, the inherent information used by the large-screen device to establish a Wi-Fi P2P connection) through the first connection or broadcasting. ) to the communication module in the smartphone.

Optionally, in S215, as a possible implementation manner, the communication module in the large-screen device can send inherent information in the information required by the Wi-Fi P2P connection of the large-screen device to the smartphone through the first connection. in the communication module. In the embodiment of this application, the inherent information in the Wi-Fi P2P connection of the large-screen device includes: a list of channels supported by the large-screen device, the SSID of the P2P group when the large-screen device creates a P2P group, and the large-screen device creates a P2P group PWD of the P2P group, whether the large-screen device itself supports Wi-Fi P2P connection, whether the large-screen device supports broadband, and device information of the large-screen device, etc.

The device information of the large-screen device may include: the device name of the large-screen device, account information of the large-screen device, the Bluetooth of the large-screen device, the status of the Wi-Fi switch, the power level of the large-screen device, and the like.

Optionally, in S215, the communication module in the large-screen device can also send the Wi-Fi data of the large-screen device to the communication module of the smartphone by broadcasting (for example, BLE broadcast, BR broadcast, Wi-Fi broadcast, etc.). Inherent information in Fi P2P connections.

Or, in S215, as another possible implementation manner, the communication module in the large-screen device can also send the Wi- Information inherent in Fi P2P connections.

After the communication module of the smartphone receives the inherent information in the information required for the Wi-Fi P2P connection of the large-screen device through the first connection and/or broadcasting, it can store the information required for the Wi-Fi P2P connection of the large-screen device inherent information in .

The above-mentioned S210 and S215 are the process of exchanging inherent information in the Wi-Fi P2P connection between the large-screen device and the smartphone.

Below, the specific process of exchanging (or also referred to as synchronizing) the variable information in the Wi-Fi P2P connection (that is, the variable information used to establish the Wi-Fi P2P connection) between the large-screen device and the smartphone will be described in detail. The flow includes S220 to S245.

S220, the driver and chip module of the smartphone sends a message to the FRAMEWORK module of the smartphone when the Wi-Fi P2P connection status of the smartphone changes, and/or the frequency of the AP (ie Wi-Fi hotspot) connected to the smartphone changes. , the message includes: at least one of the Wi-Fi P2P connection status of the smartphone and the frequency of the AP connected to the smartphone. In the embodiment of the present application, the Wi-Fi P2P connection status of the smartphone includes: the smartphone does not currently have a Wi-Fi P2P connection with any device; the smartphone currently has a Wi-Fi P2P connection with other devices , and the role of the smartphone is GO; there is currently a Wi-Fi P2P connection between the smartphone and other devices, and the role of the smartphone is either GC.

S225, the FRAMEWORK module of the smartphone sends a message to the communication module of the smartphone, where the message includes at least one of the Wi-Fi P2P connection status of the smartphone and the frequency of the AP connected to the smartphone.

S230, the communication module of the smart phone sends a message to the communication module of the large-screen device. The message includes: variable information in the Wi-Fi P2P connection of the smartphone (ie, variable information used by the smartphone to establish the Wi-Fi P2P connection).

For example, the variable information in the Wi-Fi P2P connection of the smartphone includes at least one of the Wi-Fi P2P connection status of the smartphone and the frequency of the AP to which the smartphone is connected.

Specifically, since the Wi-Fi chips of terminal devices (such as smart phones or large-screen devices) basically support the simultaneous existence of Wi-Fi stations (Wi-Fi STATION) and Wi-Fi P2P roles. Among them, the role of Wi-Fi STATION can be understood as the terminal device establishes a Wi-Fi connection by connecting to the router (Wi-Fi hotspot/AP), and the role of Wi-Fi P2P can be understood as the terminal device does not pass through the router and directly communicates with other device to connect to Wi-Fi. When the Wi-Fi STATION connection of a terminal device and the Wi-Fi P2P connection are in the same frequency band but not the same channel, the same frequency and different channels will occur, thus affecting the performance of the Wi-Fi STATION connection and Wi-Fi P2P. Therefore, the Wi-Fi STATION status of the terminal device will also affect the Wi-Fi P2P connection, and the Wi-Fi STATION status can be reflected by the frequency of the AP connected to the terminal device. Therefore, in this embodiment of the present application, after the frequency of the AP connected to the smartphone or the large-screen device changes, the smartphone or the large-screen device can synchronize the frequency of the connected AP to the devices in the trusted device list.

In addition, due to the limitation of the "Wi-Fi DIRECT" standard protocol, Wi-Fi P2P connection can only occur between GO devices and GC devices, and there is a GO device connected to a limited number of GC devices at most, and a GC device only The limitation of being able to connect 1 GO device, so before initiating a Wi-Fi P2P connection, the Wi-Fi P2P connection status of the dual-end devices (large-screen devices and smartphones) will also affect this Wi-Fi P2P connection. Therefore, in this embodiment of the present application, when the Wi-Fi P2P connection status of the smartphone or the large-screen device changes, the smartphone and the large-screen device will synchronously notify all members in the trusted device list of the Wi-Fi P2P status of the smartphone and the large-screen device. equipment.

Among them, the Wi-Fi P2P connection status of the device includes: the device does not currently have a Wi-Fi P2P connection with any device; the device currently has a Wi-Fi P2P connection with other devices, and the role of the device is GO; There is currently a Wi-Fi P2P connection between the device and other devices, and the role of the device is GC.

It should be understood that, in this embodiment of the present application, the variable information in the Wi-Fi P2P connection of the smartphone may also be included in the process of the smartphone in the Wi-Fi P2P connection, and others may change at any time, and will affect the Wi-Fi P2P The connection information is not limited in this embodiment of the present application.

Optionally, in S230, the message may be sent in the form of broadcasting (for example: BLE broadcasting, BR broadcasting, Wi-Fi broadcasting, etc.), or may also be sent through the first connection, or, through broadcasting and the first connection Both ways to send.

After receiving the variable information in the Wi-Fi P2P connection of the smartphone through the first connection and/or broadcasting, the communication module of the large-screen device can store the variable information in the Wi-Fi P2P connection of the smartphone.

It should be understood that, in S230, the timing for the communication module of the smart phone to send the variable information in the Wi-Fi P2P connection of the smart phone to the communication module of the large-screen device may be periodically sent, or may be sent on the smart phone. It is sent during the actual Wi-Fi P2P connection with the large-screen device, or, after the variable information in the Wi-Fi P2P connection of the smartphone, after a period of time, or you can also set some sending rules :

For example, after the Wi-Fi P2P connection status of the smartphone changes, immediately send the changed Wi-Fi P2P connection status of the smartphone to the communication module of the large-screen device, and when sending the Wi-Fi P2P connection status of the smartphone , if the frequency of the AP connected to the smartphone also changes, the changed frequency of the AP connected to the smartphone will be sent to the large-screen device. That is to say, if only the frequency of the AP connected to the smartphone changes, it will not individually trigger the sending of the changed frequency of the AP connected to the smartphone to the communication module of the large-screen device.

Another example: after the frequency of the AP connected to the smartphone changes, immediately send the changed frequency of the connected AP to the communication module of the large-screen device. When sending the frequency of the AP connected to the smartphone, if the smartphone Wi-Fi P2P connection If the status has also changed, the changed smartphone Wi-Fi P2P connection status will be sent to the large-screen device. That is to say, if only the Wi-Fi P2P connection status of the smartphone changes, it will not be individually triggered to send the changed Wi-Fi P2P connection status of the smartphone to the communication module of the large-screen device.

Another example: if any of the variable information in the Wi-Fi P2P connection of the smartphone changes, the smartphone will immediately send the changed information in the Wi-Fi P2P connection to the communication module of the large-screen device. That is, any one of the variable information in the Wi-Fi P2P connection of the smartphone can be sent independently without being affected by other information.

It should be understood that, in this embodiment of the present application, there is no limitation on the sequence of executing the processes of S230 and S210. S230 can be executed before S210, can also be executed after S210, or can also be executed simultaneously with S210. In other words, the smartphone sends the variable information in the Wi-Fi P2P connection of the smartphone to the large-screen device before the smartphone sends the inherent information in the Wi-Fi P2P connection of the smartphone to the large-screen device, and also It can be performed after the smartphone sends the inherent information in the Wi-Fi P2P connection of the smartphone to the large-screen device, or it can be performed simultaneously with the smartphone sending the inherent information in the Wi-Fi P2P connection of the smartphone to the large-screen device. . The embodiments of the present application are not limited.

S235, when the driver and chip module of the large-screen device change the Wi-Fi P2P connection status of the large-screen device, or the frequency of the AP (ie Wi-Fi hotspot) connected to the large-screen device changes, the FRAMEWORK module of the large-screen device Send a message, the message includes at least one of the Wi-Fi P2P connection status of the large-screen device and the frequency of the AP to which the large-screen device is connected. In this embodiment of the present application, the Wi-Fi P2P connection status of the large-screen device includes: the large-screen device currently does not have a Wi-Fi P2P connection with any device; the large-screen device currently has a Wi-Fi P2P connection with other devices. Fi P2P connection, and the role of the large-screen device is GO; there is currently a Wi-Fi P2P connection between the large-screen device and other devices, and the role of the large-screen device is any one of GC.

S240, the FRAMEWORK module of the large-screen device sends a message to the communication module of the large-screen device, the message including: at least one of the Wi-Fi P2P connection status of the large-screen device and the frequency of the AP connected to the large-screen device.

S245, the communication module of the large-screen device sends a message to the communication module of the smartphone device. The message includes: variable information in the Wi-Fi P2P connection of the large-screen device (that is, variable information used by the large-screen device to establish a Wi-Fi P2P connection).

For example, the variable information in the Wi-Fi P2P connection of the large-screen device includes: at least one of the Wi-Fi P2P connection status and the frequency of the AP to which the large-screen device is connected.

It should be understood that, in this embodiment of the present application, the variable information in the Wi-Fi P2P connection of the large-screen device may also be included in the process of the large-screen device being connected to Wi-Fi P2P, and others may change at any time, and will affect the Wi-Fi P2P connection. Information about the Fi P2P connection is not limited in this embodiment of the present application.

Optionally, in S245, the message may be sent in the form of broadcasting (for example: BLE broadcasting, BR broadcasting, Wi-Fi broadcasting, etc.), or may also be sent through the first connection, or, through broadcasting and the first connection Both ways to send.

It should be understood that, in this embodiment of the present application, there is no limitation on the sequence of executing the processes of S245 and S215. S245 can be executed before S215, can also be executed after S215, or can also be executed simultaneously with S215. In other words, the large-screen device sends the variable information in the Wi-Fi P2P connection of the large-screen device to the smartphone before the large-screen device sends the inherent information in the Wi-Fi P2P connection of the large-screen device to the smartphone. , it can also be performed after the large-screen device sends the inherent information in the Wi-Fi P2P connection of the large-screen device to the smartphone, or it can also be performed with the large-screen device to the smartphone. The inherent information is carried out at the same time. The embodiments of the present application are not limited.

Optionally, in S245, the timing for the communication module of the large-screen device to send the variable information in the Wi-Fi P2P connection of the large-screen device to the communication module of the smartphone may be periodically sent, or it may also be Set some sending rules. The rules are similar to those in S230, and are not repeated here for the sake of introduction.

The above-mentioned S220 to S245 are the processes of exchanging (or also called synchronizing) the variable information in the Wi-Fi P2P connection between the large-screen device and the smartphone.

S250, the communication module of the smartphone and the communication module of the large-screen device establish a Wi-Fi P2P connection according to the variable information and fixed information in the exchanged Wi-Fi P2P connection.

For example, when a smartphone and a large-screen device actually initiate a Wi-Fi P2P connection, the smartphone can simply send some simple signaling (such as broadcast messages, Bluetooth messages, etc.) to the large-screen device to complete Wi-Fi Fi P2P connection.

It should also be understood that, in this embodiment of the present application, there is no limitation on the sequence of executing the processes of S230 and S250. S230 can be executed before S250, or can also be executed concurrently with S250. In other words, the smartphone sends variable information in the smartphone's Wi-Fi P2P connection to the large-screen device, either before the smartphone and the large-screen device establish a Wi-Fi P2P connection, or before the smartphone and the large-screen device establish a Wi-Fi P2P connection. The device is in the process of establishing a Wi-Fi P2P connection. The embodiments of the present application are not limited.

Similarly, in this embodiment of the present application, there is no limitation on the sequence of execution of S245 and S250. S245 can be executed before S250, or can also be executed concurrently with S250. In other words, the large-screen device sends variable information in the Wi-Fi P2P connection of the large-screen device to the smartphone, either before the large-screen device and the smartphone establish a Wi-Fi P2P connection, or before the large-screen device and the smartphone establish a Wi-Fi P2P connection. The smartphone is in the process of establishing a Wi-Fi P2P connection. The embodiments of the present application are not limited.

In the method for establishing a Wi-Fi P2P connection provided in this application, after the Wi-Fi P2P device is discovered and the first connection is established, the information required for the Wi-Fi P2P connection is exchanged in stages, and the information required for the Wi-Fi P2P connection is exchanged in stages. The inherent information in the information is exchanged in advance before the Wi-Fi P2P service is initiated. After the variable information in the information required by the Wi-Fi P2P connection is changed, it is exchanged in advance before the Wi-Fi P2P service is initiated, or it is exchanged during the actual initiation of the Wi-Fi P2P connection. Therefore, when the Wi-Fi P2P connection is actually initiated, some or all of the information necessary for the Wi-Fi P2P connection has been exchanged. When the Wi-Fi P2P connection is actually initiated, only some simple signaling needs to be sent. Wi-Fi P2P connection, thereby further shortening the time spent in Wi-Fi P2P connection and improving user experience.

Optionally, in this embodiment of the present application, as another possible implementation manner, as shown in FIG. 5 , on the basis of the steps shown in FIG. 4 , before S210 , the method further includes: a smartphone and a large The screen device establishes a first connection by scanning and performs inter-device security authentication based on the first connection, that is, the steps described in S204, S206 to S208 described below.

S204, both the smart phone and the large-screen device are connected to the routing hotspot at home, and the driver and chip module of the smart phone and the large-screen device automatically start background scanning to discover the device. In this embodiment of the present application, both the smartphone and the large-screen device can use one or more methods of BLE scanning, classic Bluetooth scanning, wireless local area networks (WLAN) scanning, or Wi-Fi P2P scanning to discover devices. to discover the device. The classic Bluetooth includes at least one of two types of Bluetooth: BR and Bluetooth enhanced data rate (EDR).

It should be understood that, in the embodiments of the present application, when the smartphone and the large-screen device perform background scanning, periodic background scanning is performed.

After S204, S205 can be executed.

After S205, S206 to S208 may be performed.

S206, the communication module in the smartphone and the communication module in the large-screen device negotiate a key based on the first connection to obtain an encryption key and a decryption key, thereby completing the device security authentication based on the first connection.

For example, a smartphone determines the GO and GC roles according to the device type and device status (battery power, etc.) of itself and the large-screen device, Wi-Fi P2P connection status, etc. For example: a smartphone is a GO device, and a large-screen device is a GC device. The smartphone determines which frequency the GO device is ultimately built on according to the Wi-Fi STATION channel of the large-screen device, the list of supported 5G channels, whether it supports broadband, etc., and determines the SSID and PWD of the Wi-Fi P2P group. That is, the connection method of Wi-Fi P2P is determined.

The notification message includes: the frequency of Wi-Fi P2P group establishment, the role assignment of GC devices and GO devices, the SSID and PWD of the Wi-Fi P2P group, the MAC address, or IP address and port number of the large-screen device.

S2521, the driver and chip module of the smartphone join the Wi-Fi P2P group according to the notification message of the successful establishment of the Wi-Fi P2P group.

S2522, the driver and chip module of the smart phone notifies the communication module in the smart phone of the successful joining of the Wi-Fi P2P group.

S2523, after receiving the message, the communication module in the smart phone sends a message of successfully joining the Wi-Fi P2P group to the application on the smart phone.

S2524, after the application on the smart phone receives the message of successfully joining the Wi-Fi P2P group, it establishes a transmission channel based on the Wi-Fi P2P connection with the application on the large-screen device (for example, a file sharing application).

After S2524, a Wi-Fi P2P connection is established between the smartphone and the large-screen device.

S2525, the application on the smartphone starts file sharing to the application on the large-screen device based on the transmission channel of the Wi-Fi P2P connection.

The method for establishing a Wi-Fi P2P connection provided by this application, when performing Wi-Fi P2P device discovery, various discovery methods (such as BLE discovery, LAN discovery, Wi-Fi P2P discovery, broadcast discovery, etc.) can be used for device discovery , can support a variety of discovery methods, and support the use of different types of connection methods or broadcast methods for information interaction, which improves the versatility and scalability, and can be used as a platform-level capability for various applications. After the device is discovered, the information required for the Wi-Fi P2P connection will be exchanged in stages, and the inherent information in the information required by the Wi-Fi P2P connection (for example: the list of channels supported by the device, P2P group SSID, PWD, whether Support broadband (such as whether to support 160MHz), device information, etc., are exchanged in advance before the Wi-Fi P2P service is initiated. Change the variable information in the information required for Wi-Fi P2P connection (for example: Wi-Fi P2P connection status of the device, role, frequency of the AP (ie Wi-Fi hotspot) connected to the device, etc.) after the variable information changes , exchange in advance before the Wi-Fi P2P service is initiated, or exchange in the process of actually initiating the Wi-Fi P2P connection. Therefore, when the Wi-Fi P2P connection is actually initiated, some or all of the information necessary for the Wi-Fi P2P connection has been exchanged. When the Wi-Fi P2P connection is actually initiated, only some simple signaling (such as broadcast message, Bluetooth message, etc.) to complete the Wi-Fi P2P connection, thereby further shortening the time spent in the Wi-Fi P2P connection and improving the user experience. Moreover, it can be used in different product platforms to meet the needs of different upper-layer applications.

Optionally, in this embodiment of the present application, after S204, for S205: the communication module in the smartphone and the communication module in the large-screen device establish the first connection through interactive broadcast messages, there may be two different implementations. Way:

The first implementation manner: For example, as shown in Figure 8: S205 may include:

In S2051a, after the smartphone driver and the chip module enable background scanning to discover devices, the communication module in the smartphone sends a first broadcast message, which may be a BLE broadcast message, a BR broadcast message, or a Wi-Fi broadcast message. The first broadcast message carries: the device identifier (deviceId) of the smart phone, the device type, the connection address, the version number, and the like. For example, the connection address may include: the MAC address of the smart phone, the IP address of the smart phone, the port number, and the like.

S2052a, after the driver and the chip module of the large-screen device enable background scanning to discover the device, and after the communication module of the large-screen device receives the first broadcast message.

S2053a, the communication module of the large-screen device replies with a second broadcast message, where the second broadcast message may be a BLE broadcast message, a BR broadcast message, or a Wi-Fi broadcast message, and the like. The second broadcast message includes: a device identifier (deviceId) of the large-screen device, a device type, a connection address, a version number, and the like. For example, the connection address may include: the MAC address of the large-screen device, the IP address and port number of the large-screen device, and the like.

S2054a, after receiving the second broadcast message, the communication module in the smartphone establishes a first connection with the large-screen device according to the connection address included in the second broadcast message. For example, if it is based on a MAC address, the first connection established is a BLE connection or a BR connection; if it is based on a MAC address, an IP address and a port number, the first connection established is a socket connection based on a local area network.

After S2054a, S206 can be executed.

The second implementation manner: For example, as shown in Figure 9: S205 may include:

In S2051b, after the smartphone driver and the chip module enable background scanning to discover devices, the communication module in the smartphone sends a first broadcast message, which may be a BLE broadcast message, a BR broadcast message, or a Wi-Fi broadcast message. The first broadcast message carries: the device identifier (deviceId) of the smart phone, the device type, the connection address, the version number, and the like. For example, the connection address may include: the MAC address of the smart phone, the IP address of the smart phone, the port number, and the like.

S2052b, after the driver and the chip module of the large-screen device enable background scanning to discover the device, the communication module of the large-screen device receives the first broadcast message.

S2053b, the communication module of the large-screen device establishes a first connection with the smartphone according to the connection address included in the first broadcast message. For example, if it is based on the MAC address of the smartphone, the first connection established is a BLE connection or a BR connection; if it is based on the IP address and port number of the smartphone, the first connection established is a local area network-based socket connection.

After S2053b, S206 can be executed.

The method for establishing a Wi-Fi P2P connection provided by this application, when performing Wi-Fi P2P device discovery, various discovery methods (such as BLE discovery, LAN discovery, Wi-Fi P2P discovery, broadcast discovery, etc.) can be used for device discovery , can support a variety of discovery methods, and support the use of different types of connection methods or broadcast methods for information interaction, which improves the versatility and scalability, and can be used as a platform-level capability for various applications. After the device is discovered, the information required for the Wi-Fi P2P connection will be exchanged in stages, and the inherent information in the information required by the Wi-Fi P2P connection (for example: the list of channels supported by the device, P2P group SSID, PWD, whether Support broadband (such as whether to support 160MHz), device information, etc. to exchange in advance before the Wi-Fi P2P service is initiated, and the variable information in the information required for Wi-Fi P2P connection (for example: device Wi-Fi P2P connection Status, role, frequency of the AP (ie Wi-Fi hotspot) connected to the device, etc.) After the variable information changes, it is exchanged in advance before the Wi-Fi P2P service is initiated, or the Wi-Fi P2P connection process is actually initiated. exchange. Therefore, when the Wi-Fi P2P connection is actually initiated, some or all of the information necessary for the Wi-Fi P2P connection has been exchanged. When a Wi-Fi P2P connection is actually initiated, it only needs to send some simple signaling (such as broadcast messages, Bluetooth messages, etc.) to complete the Wi-Fi P2P connection, thereby further shortening the time used for the Wi-Fi P2P connection. Improve user experience. Moreover, it can be used in different product platforms to meet the needs of different upper-layer applications.

It should be understood that the method provided in the present application is described above by taking establishing a Wi-Fi P2P connection as an example. In some other possible implementation manners of the present application, for example, in the scenario of establishing a Wi-Fi connection between the first electronic device and the second electronic device, the concepts provided by the present application can also be used, which will be described in detail below.

In the embodiment of the present application, as a possible implementation manner, it is assumed that the first electronic device is a terminal device, and the second electronic device is an access point device (access point, AP). For example, the second electronic device may be a router. In this case, before the user triggers the terminal device to establish a Wi-Fi connection with the router, since the router already exists, before the Wi-Fi connection is established, the terminal device can be discovered through the background networking and obtain the SSID and PWD of the router, etc. Wi-Fi connection inherent information (that is, information that remains unchanged for a period of time during a Wi-Fi connection). In addition, since the router supports the frequency hopping function, the working frequency or channel of the router may change at any time. Therefore, after the working frequency or channel of the router changes, the router can change the working frequency of the changed working frequency. , channel and other information (for example, through Bluetooth packets, Wi-Fi packets, etc.) to the terminal device, or the terminal device can also actively request the router for information such as the frequency and channel of the router's operation. After the terminal device obtains the variable information of the Wi-Fi connection such as the frequency and channel of the router's operation (that is, during the Wi-Fi connection process, it may change at any time, and the information that will affect the Wi-Fi connection), the user actually triggers the terminal When the device establishes a Wi-Fi connection with the router, since the terminal device has previously acquired the inherent information (including the router's SSID and PWD, etc.) and variable information (including the router's working frequency, channel, etc.) , so that when the user uses the terminal device to initiate a Wi-Fi connection, most of the information has been exchanged. The first terminal device directly scans the operating frequency and channel of the router, and only the terminal device needs to send some simple signaling. (For example, sending signaling through broadcast messages, Bluetooth messages, etc.) can complete the Wi-Fi connection, thereby further shortening the time-consuming of the Wi-Fi connection and improving the user experience.

In this embodiment of the present application, as another possible implementation manner, it is assumed that the first electronic device is a terminal device, and the second electronic device is a soft AP (soft AP). A soft AP can be understood as a terminal device connected to a wired network or a wireless network, and the terminal device is used as a Wi-Fi hotspot to provide a Wi-Fi network for other terminal devices. For example, soft APs may include smart phones, tablet computers, netbooks, PDAs, computer handheld communication devices, etc. used by the user. In this case, it is assumed that the first electronic device is the first terminal device used by the user, and the second electronic device is the second terminal device used by the user. Before the user triggers the first terminal device and the second terminal device to establish a Wi-Fi connection, the first terminal device and the second terminal device may exchange their respective Wi-Fi connection-specific information such as SSID and PWD during Wi-Fi connection (that is, information that remains unchanged for a period of time during Wi-Fi connection). In addition, the first terminal device and the second terminal device can exchange Wi-Fi connection variable information such as their respective working frequencies and channels through broadcast messages (eg, Bluetooth messages, etc.) (in the Wi-Fi connection process, may change at any time and affect Wi-Fi connection information). When the user actually triggers the first terminal device to establish a Wi-Fi connection with the second terminal device, because the first terminal device has previously acquired the inherent information (including the SSID of the second terminal device) for establishing a Wi-Fi connection with the second terminal device and PWD, etc.) and variable information (including the working frequency, channel, etc. of the second terminal device), so that when the user uses the first terminal device to actually initiate a Wi-Fi connection, most of the information has been exchanged, and the first terminal device The device only needs to send some simple signaling (such as broadcast packets, Bluetooth packets) to complete the Wi-Fi connection, thereby further shortening the time-consuming of the Wi-Fi connection and improving the user experience.

For example, in S205 of the above-mentioned method 200, when the first connection between the smartphone and the large-screen device is a Wi-Fi connection, the smartphone and the large-screen device may establish a Wi-Fi connection using the above two methods.

Optionally, before the first electronic device and the second electronic device establish a Wi-Fi connection, the first electronic device and the second electronic device may further establish a communication connection in other manners, for example, the communication connection may be a Bluetooth connection or the like. After the communication connection is established, before the user actually triggers the first electronic device and the second electronic device to establish a Wi-Fi connection, the first electronic device and the second electronic device can exchange the inherent information and available information in the Wi-Fi connection through the communication connection. Changing information can increase the rate of information exchange and further shorten the time-consuming of Wi-Fi connections.

Optionally, the first electronic device and the second electronic device may also exchange inherent information and variable information in the Wi-Fi connection through broadcast messages (eg, Bluetooth messages, Wi-Fi messages, etc.). The embodiments of the present application are not limited herein.

It should be understood that before the two-terminal device actually establishes a wireless communication connection provided by the present application, the two-terminal device exchanges information necessary for establishing the communication connection in advance, so that when the two-terminal device actually initiates the communication connection, most of the information has been exchanged. Complete, the method of completing the communication connection only requires the two-end devices to send some simple signaling, which is not only applicable to the scenarios including establishing Wi-Fi connection and Wi-Fi P2P connection, but also applicable to establishing other communication connections ( For example, in a scenario of Bluetooth and Zigbee, this embodiment of the present application does not limit it.
