Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method, electronic equipment and storage medium. Background Art

[0002] Currently, terminal devices (such as mobile phones and tablets) can directly exchange information based on peer-to-peer (P2P) technology to share computing resources and services. P2P technology refers to the transmission of information between two terminal devices directly through a channel without the intervention of an intermediate link or server. For example, Figure 1 As shown, the mobile phone 101 and the computer 102 can use P2P technology to project screens and share computing resources.

[0003] At present, there are some situations where the channel for communication between the terminal device and the wireless router is different from the channel for P2P communication between two terminal devices, resulting in the need for the terminal device to perform time-sharing transmission between two different channels. For example, the data sending end device can transmit data with the wireless router within a preset first time period, and will switch to the P2P channel to perform P2P data transmission with the data receiving end device within a preset second time period, and will switch to the channel for communication with the wireless router again within a preset third time period. The switching of the terminal device between different channels results in a shorter time slice for P2P data transmission between terminal devices. For example, in the screen projection scenario, it is necessary to wait until the time slice of P2P data transmission between the two terminal devices corresponds to each other before the screen projection data can be transmitted, which can easily cause freezes and delays in the projection screen, affecting the user experience. Summary of the invention

[0004] To solve the above problems, the present application provides a communication method, an electronic device and a storage medium.

[0005] In a first aspect, the present application provides a communication method, the method comprising: a first terminal device is connected to a first wireless access device based on a first channel; the first terminal device receives a first instruction to establish a point-to-point communication connection with a second terminal device; it is determined that both the first terminal device and the second terminal device support point-to-point communication based on the first channel; and point-to-point communication between the first terminal device and the second terminal device is established based on the above-mentioned first channel.

[0006] In the present application, the first channel may be any channel in the Dynamic Frequency Selection (DFS) channel; the first instruction may be the indication information for point-to-point communication received by the first terminal device during the device discovery process and received by the second terminal device. For example, if the first terminal device is a computer and the second terminal device is a mobile phone, the first instruction may be a request frame sent by the mobile phone to the computer after the screen projection of the mobile phone is turned on; the first terminal device may be any electronic device such as a mobile phone, a tablet, a computer, a virtual reality (VR) device, a wearable device, an augmented reality (AR) device, etc.; the first wireless access device may be a wireless router, a wireless access point, etc. mentioned later; the second terminal device may be any electronic device such as a mobile phone, a tablet, a computer, a VR device, a wearable device, an AR device, etc.

[0007] It can be understood that in the present application, when the first terminal device has accessed the wireless network based on the first channel, it is necessary to determine whether the configurations of the first terminal device and the second terminal device both support point-to-point communication (i.e., P2P communication) on the first channel. When it is determined that the configurations of the first terminal device and the second terminal device both support the creation of P2P communication on the first channel, a P2P channel between the two terminal devices can be established based on the first channel of the above-mentioned access network.

[0008] Based on the above scheme, it can be ensured that the channel for communication between at least one end device and the wireless access device is the same as the channel for P2P communication between two terminal devices, thereby effectively reducing the occurrence of time-sharing switching scenarios between different channels of terminal devices, increasing the time for P2P channel data transmission, avoiding screen freezes and other phenomena, and improving user experience.

[0009] In a possible implementation, the first channel is a dynamic frequency selection channel.

[0010] In this application, DFS channels are multiple channels with automatic switching function under the 5GHz wireless frequency band. When the device is connected to the DFS channel under the 5GHz frequency band, when a radar signal is detected in one of the channels, it can automatically switch to other channels to avoid interference from the radar signal.

[0011] It can be understood that, in the present application, the first channel can be any channel in the DFS channel.

[0012] It can be understood that in the present application, the first terminal device can be connected to the first wireless access device based on any channel in the DFS channel to access the wireless network.

[0013] In a possible implementation, the method further includes: if it is determined that the first terminal device or the second terminal device does not support point-to-point communication based on the first channel, and it is determined that the second terminal device is connected to the second wireless access device based on the second channel, wherein the second channel includes any channel in the non-dynamic frequency selection channel; establishing point-to-point communication between the first terminal device and the second terminal device based on the second channel.

[0014] In the present application, the first channel may be any channel in the DFS channels; the second channel may be any channel in the non-DFS channels.

[0015] It can be understood that in the present application, when it is determined that the first terminal device is connected to the first wireless access device based on any channel in the DFS channel, and it is determined that the configuration of the first terminal device or the second terminal device does not support the creation of P2P communication on the first channel, it is necessary to judge the wireless network connection status of the second terminal device. If it is determined that the second terminal device is connected to the second wireless access device based on any channel in the non-DFS channel, P2P communication between the two terminal devices can be established based on the non-DFS channel. In this way, it can be ensured that the channel for communication between the second terminal device and the wireless access device is the same as the channel for P2P communication between the two terminal devices, thereby avoiding the occurrence of the scenario of time-sharing switching between different channels of the second terminal device, and improving the channel transmission performance and user experience.

[0016] In a possible implementation, the method also includes: if it is determined that the first terminal device or the second terminal device does not support point-to-point communication based on the first channel, and it is determined that the second terminal device is connected to the second wireless access device based on a third channel, wherein the third channel is a dynamic frequency selection channel; then establishing point-to-point communication between the first terminal device and the second terminal device based on a fourth channel, wherein the fourth channel includes any channel in the non-dynamic frequency selection channel.

[0017] In the present application, the first channel may be any channel in the DFS channels; the third channel may be any channel in the DFS channels; and the fourth channel may be any channel in the non-DFS channels.

[0018] It can be understood that in the present application, when it is determined that the first terminal device is connected to the first wireless access device based on any channel in the DFS channel, and at the same time it is determined that the configuration of the first terminal device or the second terminal device does not support the creation of P2P communication on the first channel, it is necessary to judge the wireless network connection status of the second terminal device. If it is determined that the second terminal device is connected to the second wireless access device based on any channel in the DFS channel, P2P communication between the two terminal devices can be established based on the fourth channel, that is, any channel in the non-DFS channel (for example, channel 149 configured by default by the system).

[0019] In a possible implementation, the method also includes: if it is determined that the first terminal device or the second terminal device does not support point-to-point communication based on the first channel, and it is determined that the second terminal device is not connected to the second wireless access device; establishing point-to-point communication between the first terminal device and the second terminal device based on a fourth channel, wherein the fourth channel includes any channel in the non-dynamic frequency selection channel.

[0020] In the present application, the first channel may be any channel in the DFS channels; and the fourth channel may be any channel in the non-DFS channels.

[0021] It can be understood that in the present application, when it is determined that the first terminal device is connected to the first wireless access device based on any channel in the DFS channel, and at the same time it is determined that the configuration of the first terminal device or the second terminal device does not support the creation of P2P communication on the first channel, it is necessary to judge the wireless network connection status of the second terminal device. If it is determined that the second terminal device is not connected to the second wireless access device, P2P communication between the two terminal devices can be established based on the fourth channel, i.e., any channel in the non-DFS channel (for example, channel 149 configured by default by the system).

[0022] In a possible implementation, the method further includes: the first terminal device is not connected to the first wireless access device; if it is determined that the second terminal device is connected to the second wireless access device based on a second channel, wherein the second channel includes any channel in a non-DFS channel; point-to-point communication between the first terminal device and the second terminal device is established based on the second channel.

[0023] In the present application, the second channel may be any channel of the non-DFS channels.

[0024] It can be understood that in this application, when it is determined that the first terminal device is not connected to the first wireless access device to access the wireless network, it is necessary to judge the wireless network connection status of the second terminal device. If it is determined that the second terminal device is connected to the second wireless access device based on any channel in the non-DFS channel, P2P communication between the two terminal devices can be established based on the non-DFS channel. In this way, the first terminal device is a single-channel communication, and the channel for communication between the second terminal device and the second wireless access device is the same as the channel for P2P communication between the two terminal devices, which can avoid time-sharing switching between different channels between the first terminal device and the second terminal device, effectively reduce the occurrence of time-sharing multiplexing scenarios, and improve channel transmission performance and user experience.

[0025] In a possible implementation, the method also includes: the first terminal device is not connected to the first wireless access device; if it is determined that the second terminal device is connected to the second wireless access device based on a third channel, and it is determined that both the first terminal device and the second terminal device support point-to-point communication based on the third channel, wherein the third channel is a dynamic frequency selection channel; point-to-point communication between the first terminal device and the second terminal device is established based on the third channel.

[0026] In the present application, the third channel may be any channel in the DFS channels.

[0027] It can be understood that in the present application, when it is determined that the first terminal device is not connected to the first wireless access device to access the wireless network, it is necessary to judge the wireless network connection status of the second terminal device. If it is determined that the second terminal device is connected to the second wireless access device based on any channel in the DFS channel, it is necessary to judge whether the configurations of the first terminal device and the second terminal device both support point-to-point communication (i.e., P2P communication) on the third channel. When it is determined that the configurations of the first terminal device and the second terminal device both support the creation of P2P communication on the third channel, a P2P channel between the two terminal devices can be established based on the third channel of the second terminal device accessing the network.

[0028] Based on the above solution, the first terminal device uses a single-channel communication, and the channel for communication between the second terminal device and the wireless access device is the same as the channel for P2P communication between the two terminal devices. This can avoid time-sharing switching between different channels between the first terminal device and the second terminal device, effectively reduce the occurrence of time-sharing multiplexing scenarios, and improve channel transmission performance and user experience.

[0029] In a possible implementation, the method also includes: the first terminal device is not connected to the first wireless access device; if it is determined that the second terminal device is connected to the second wireless access device based on a third channel, and it is determined that the first terminal device or the second terminal device does not support point-to-point communication based on the third channel, wherein the third channel is a dynamic frequency selection channel; establishing point-to-point communication between the first terminal device and the second terminal device based on a fourth channel, wherein the fourth channel includes any channel in the non-dynamic frequency selection channel.

[0030] In the present application, the third channel may be any channel in the DFS channels; and the fourth channel may be any channel in the non-DFS channels.

[0031] It can be understood that in the present application, when it is determined that the first terminal device is not connected to the first wireless access device to access the wireless network, it is necessary to judge the wireless network connection status of the second terminal device. If it is determined that the second terminal device is connected to the second wireless access device based on any channel in the DFS channel, it is necessary to judge whether the configurations of the first terminal device and the second terminal device both support P2P communication on the third channel. When it is determined that the configuration of the first terminal device or the second terminal device does not support the creation of P2P communication on the third channel, a P2P channel between the two terminal devices can be established based on the fourth channel, i.e., any channel in the non-DFS channel.

[0032] In a possible implementation, the method further includes: the first terminal device is not connected to the first wireless access device; if it is determined that the second terminal device is not connected to the second wireless access device; establishing point-to-point communication between the first terminal device and the second terminal device based on a fourth channel, wherein the fourth channel includes any channel in a non-dynamic frequency selection channel.

[0033] In the present application, the fourth channel may be any channel of the non-DFS channels.

[0034] It can be understood that in the present application, when it is determined that the first terminal device is not connected to the first wireless access device to access the wireless network, it is necessary to judge the wireless network connection status of the second terminal device. If it is also determined that the second terminal device is not connected to the second wireless access device, P2P communication between the two terminal devices can be established based on the fourth channel, i.e., any channel in the non-DFS channel (for example, channel 149 configured by default in the system).

[0035] In a possible implementation, the method further includes: if the first terminal device is connected to the first wireless access device based on the fifth channel; establishing point-to-point communication between the first terminal device and the second terminal device based on the fifth channel, wherein the fifth channel includes any channel in the non-dynamic frequency selection channel.

[0036] In the present application, the fifth channel may be any channel of the non-DFS channels.

[0037] It can be understood that in the present application, when it is determined that the first terminal device is connected to the first wireless access device based on any channel in the non-DFS channel, there is no need to judge the configuration of the first terminal device and the second terminal device, and the P2P communication between the first terminal device and the second terminal device can be directly established based on the fifth channel. In this way, it can be ensured that the channel for communication between at least one end device and the wireless access device is the same as the channel for P2P communication between the two terminal devices, thereby effectively reducing the occurrence of time-sharing switching scenarios between different channels of the terminal device, and improving the channel transmission performance and user experience.

[0038] In a possible implementation, the first terminal device is a group owner device, and the second terminal device is a group client device.

[0039] In the present application, the first terminal device may be a master device group owner (Group Owner, GO), and the second terminal device may be a slave device group client (Group Client, GC).

[0040] It can be understood that in the present application, when the first terminal device and the second terminal device perform point-to-point communication, the role of GO is similar to that of a wireless access device, GC implements the functions of the terminal device, and GC connects to GO similarly to the terminal device connecting to a wireless router.

[0054] The illustrative embodiments of the present application include, but are not limited to, a communication method, an electronic device, and a storage medium.

[0055] In order to more clearly understand the solution of the present application, the relevant field terms involved in the present application are first explained.

[0056] Channel: refers to the channel through which signals are transmitted in a communication system, which is composed of the transmission medium through which signals are transmitted from the transmitter to the receiver. Taking Wireless Fidelity (WiFi) as an example, each frequency band commonly used by WiFi is divided into multiple channels. For example, according to the IEEE 802.11 protocol, the 2.4GHz WiFi band is divided into 13 overlapping channels, each with a width of 22MHz, and the 5GHz WiFi band is divided into 201 channels.

[0057] P2P: An end-to-end communication technology that communicates in a peer-to-peer manner without distinguishing between clients and servers. The resources and services in the network are dispersed across all nodes. The transmission of information and the implementation of services are carried out directly between nodes without the intervention of intermediate links and servers. For example, the first terminal device and the second terminal device can directly transmit data based on P2P technology.

[0058] Dynamic Frequency Selection (DFS) channel: DFS channels are multiple channels with automatic switching function in the 5GHz wireless frequency band. When a device is connected to a DFS channel in the 5GHz band and a radar signal is detected in one of the channels, it can automatically switch to other channels to avoid interference from the radar signal.

[0059] The following is a brief description of the application background of the method provided in the embodiment of the present application.

[0060] At present, there are some situations where the channel for communication between the terminal device and the wireless router (i.e., the station (STA) channel) is different from the channel for P2P communication between two terminal devices, resulting in the need for the terminal device to perform time-sharing transmission between two different channels. For example, the time-sharing mode is 25ms / 25ms time-sharing, and the switching takes 5ms, which means that after the terminal device works on the STA channel for 25ms, it will switch to the P2P channel to transmit data with another terminal device, where the switching process takes 5ms. After the terminal device switches to the P2P channel and works for 25ms, it will switch to the STA channel again to communicate with the wireless router. The switching of the terminal device between different channels results in a shorter time slice for data transmission between terminal devices. For example, in the screen projection scenario, it is necessary to wait until the P2P time slice between the two devices corresponds before data transmission can be performed, resulting in freezes and delays in the projection screen, affecting the user experience.

[0061] The following first introduces the transmission method by taking the scenario where the P2P channel of one terminal device is the same as the STA channel and the P2P channel of another terminal device is different from the STA channel (i.e., single-ended same frequency different channels) as an example.

[0062] For example, Figure 2A As shown, the mobile phone 101 and the wireless router 100 establish a communication connection based on the dynamic frequency selection (Dynamic Frequency Selection, DFS) channel 60, and the tablet 201 and the wireless router 200 establish a communication connection based on the 5G frequency band 40 channel. When the mobile phone 101 and the tablet 201 establish a P2P communication connection, the STA channel (5G frequency band 40 channel) corresponding to the tablet 201 is selected as the P2P channel.

[0063] Since the STA channel and P2P channel of the mobile phone 101 are different, the mobile phone 101 needs to switch between the two channels in time division, such as Figure 2B As shown, in the P2P time slice, the mobile phone 101 communicates with the tablet 201 through the P2P channel; in the STA time slice, the mobile phone 101 communicates with the wireless router 100 through the DFS channel 60. Since the mobile phone 101 needs to switch between different channels, and switching channels also takes a certain amount of time, the working time for P2P data transmission with the tablet 201 is too short, resulting in freezes, timeouts, etc., affecting the user experience.

[0064] The following introduces the transmission method by taking the scenario where the P2P channels and STA channels of two terminal devices are different (i.e., the two ends have the same frequency but different channels) as an example.

[0065] For example, Figure 3AAs shown, both the mobile phone 101 and the tablet 201 establish a communication connection with the wireless router 100 through the DFS channel 60, and at the same time, the mobile phone 101 and the tablet 201 transmit data through the P2P channel (5G band 40 channel). Since the STA channel and the P2P channel of the mobile phone 101 and the tablet 201 are both the same frequency but different channels, it is necessary to perform time-sharing switching between the two channels at the same time, such as Figure 3B As shown, in the P2P time slice, the mobile phone 101 and the tablet 201 communicate through the P2P channel; in the STA time slice, the mobile phone 101 and the wireless router 100 communicate through the DFS channel, and the tablet 201 and the wireless router 100 communicate through the DFS channel. Figure 3B It can be seen that when the mobile phone 101 and the tablet 201 communicate, the P2P working time is too short, which will cause freezes, timeouts and other phenomena.

[0066] In some embodiments, since the time used for P2P time slice configuration, channel switching and STA time slice configuration of the mobile phone 101 and the tablet 201 may be different, the P2P time slice may not completely correspond during P2P communication, for example, Figure 3C As shown, the mobile phone 101 adopts 20ms / 20ms time-sharing, and the tablet 201 adopts 25ms / 25ms time-sharing. Since the time-sharing time slices of the mobile phone 101 and the tablet 201 are different, the two terminal devices will switch to the P2P channel at the same time only in a very short period of time, resulting in a shorter time for the P2P channel to transmit data, and the phenomena of freeze, blurred picture, video frame loss, timeout, etc. are more serious, affecting the user experience.

[0067] To solve the above problems, an embodiment of the present application provides a communication method. When a local device (e.g., a first terminal device) is preparing to establish a P2P connection with a peer device (e.g., a second terminal device), when the local device has accessed a wireless network based on a first channel, a P2P channel between the two terminal devices can be established based on the first channel of the access network. For example, the local device can send a request message for establishing a P2P channel to the peer device, and the request message may include the first channel information of the access network, so as to establish a P2P channel between the two terminal devices based on the first channel of the access network. In this way, it can be ensured that the STA channel and the P2P channel of at least one end device are the same, thereby effectively reducing the occurrence of time-sharing switching scenarios between different channels of the terminal device, increasing the time for the P2P channel to transmit data, avoiding the phenomenon of screen freeze, etc., and improving the user experience.

[0068] In some embodiments, if the above-mentioned first channel is any channel in the DFS channel, that is, the local device has accessed the wireless network based on any channel in the DFS channel, since not all devices support the creation of P2P communication in the DFS channel, therefore, when determining that the local device accesses the wireless network based on any channel in the DFS channel, it is possible to judge whether the configurations of the local device and the opposite device both support the creation of P2P communication in the DFS channel. When it is determined that the configurations of the local device and the opposite device both support the creation of P2P communication in the DFS channel, a P2P channel between the two terminal devices can be established based on the above-mentioned DFS channel of the access network.

[0069] It can be understood that in some embodiments, the local device and the opposite device can configure a software program for implementing the creation of P2P communication in the DFS channel at the framework layer in the software architecture to support the terminal device to create P2P communication in the DFS channel. The local device can send a request to the opposite device through a near field communication method such as Bluetooth and near field communication technology (NFC) to obtain whether the opposite device supports the creation of P2P communication in the DFS channel.

[0070] In some embodiments, such as Figure 4A As shown, taking the local device as mobile phone 101 and the opposite device as tablet 201 as an example, if mobile phone 101 connects to a wireless access point (AP) based on any channel in the DFS channel to access the wireless network, and the chips of mobile phone 101 and tablet 201 both support DFS channels to establish P2P communication, the DFS channel of mobile phone 101 can be added to the P2P channel list, and the P2P channel can be established on the DFS channel of mobile phone 101, so that the STA channel and P2P channel of mobile phone 101 are the same. In this way, at least one end device can avoid time-sharing switching between the P2P channel and the DFS channel, reduce P2P channel data transmission anomalies, and improve user experience.

[0071] In some embodiments, Figure 4B As shown, taking the local device as mobile phone 101 and the opposite device as tablet 201, if mobile phone 101 is not connected to the wireless network, and if mobile phone 101 determines that tablet 201 connects to the AP through any channel in the DFS channel to access the wireless network, if the chips of mobile phone 101 and tablet 201 both support the creation of P2P communication in the DFS channel, the DFS channel of tablet 201 can be added to the P2P channel list, and the P2P channel can be established on the DFS channel of the opposite device. In this way, the local device is a single-channel communication, and the P2P channel of the opposite device and the DFS channel are the same frequency and channel, which can avoid time-sharing switching between different channels between the local device and the opposite device, effectively reduce the occurrence of time-sharing multiplexing scenarios, and improve channel transmission performance and user experience.

[0072] In some embodiments, if the local device has accessed the wireless network based on any channel in the DFS channel, but if the chip of the local or opposite electronic device does not support the creation of P2P communication in the DFS channel, at this time, if the opposite device accesses the wireless network based on the DFS channel, or the opposite device has not accessed the wireless network, other channels (for example, the 149 channel configured by default in the system, etc.) can be used as P2P channels to establish a P2P communication connection; if the opposite device accesses the wireless network by connecting to a non-DFS channel, the channel of the opposite device can be used as a P2P channel to establish a communication connection between the local device and the opposite device.

[0073] In some embodiments, if the local device establishes wireless communication with the AP through a non-DFS channel, when the two terminal devices use the P2P function to transmit data, the non-DFS channel for establishing wireless communication between the local device and the AP can be added to the P2P channel list, and the local device channel can be used as the P2P channel to establish a P2P communication connection.

[0074] In some embodiments, if the local device is not connected to the wireless network, and the local device determines that the opposite device connects to the wireless network through a non-DFS channel to connect to the wireless access point, the opposite device channel can be used as a P2P channel to establish a P2P communication connection between the local device and the opposite device.

[0075] In some embodiments, if the local device is not connected to the wireless network, and it is determined that the opposite device is connected to the wireless network through the DFS channel to connect to the wireless access point, but if the local or opposite electronic device chip does not support the creation of P2P communication in the DFS channel, any other channel (for example, the system default configuration channel 149, etc.) can be used as a P2P channel to establish a P2P communication connection between the local device and the opposite device.

[0076] In some embodiments, if neither the local device nor the opposite device is connected to a wireless network, any other channel (eg, channel 149 configured by default in the system, etc.) can be used as a P2P channel to establish a P2P communication connection between the local device and the opposite device.

[0077] In this way, the method in this application can reduce P2P communication data transmission anomalies, improve P2P communication performance, and enhance user experience.

[0078] In some embodiments, before establishing a P2P channel, the two-end devices generally need to perform device discovery first, for example, Figure 1In the application scenario of screen projection shown, the screen projection of the mobile phone 101 is turned on, the mobile phone 101 will send a request frame, the computer 102 receives the request frame sent by the mobile phone, and returns a response frame to the mobile phone, so that the mobile phone 101 and the computer 102 can discover each other. In some embodiments, the request frame and the response frame can carry indication information for indicating that a P2P connection is to be established to complete the screen projection to trigger the establishment of a P2P connection, etc.

[0079] In some embodiments, during the device discovery process, the device as the slave device group client (Group Client, GC) and the device as the master device group owner (Group Owner, GO) can also be determined by pre-setting or two-way negotiation. For example, the pre-setting method may include: pre-setting a large-screen device as the GO, or pre-setting a terminal device that can support more functions as the GO, and the embodiments of the present application do not make specific limitations on this.

[0097] The following is a detailed description of the communication method in the embodiment of the present application based on the terminal device mentioned in the embodiment of the present application.

[0098] Firstly based on Figure 6 The flow chart shown in the figure details the communication method in the present application. Specifically, the method comprises the following steps:

[0099] S601: A GO is created based on the first terminal device, and a GC is created based on the second terminal device.

[0100] It can be understood that in the embodiments of the present application, when the terminal devices share computing resources and services, data information can be directly transmitted through P2P technology, such as screen projection, multi-device collaboration, face-to-face quick transmission, etc. When connecting to P2P communication, the terminal device will scan and search for the peer device, and the two parties will negotiate to determine the GO end and the GC end. In the P2P mode, the role of GO is similar to that of a wireless access point AP, and GC implements the functions of the terminal device. The connection between GC and GO is similar to the connection between a terminal device and a wireless router.

[0101] In some embodiments, the terminal device can scan and search for the peer device through Bluetooth, near field communication (NFC), etc., and initiate a P2P communication request to the peer device. For example, after the terminal device turns on the Bluetooth function, it can discover the peer device through Bluetooth and initiate a P2P communication request to the peer device. For another example, when the NFC function of the terminal device is turned on, the user touches the NFC area with the handheld terminal device, and the terminal device will initiate a P2P communication request to the other party. The embodiments of the present application do not specifically limit this.

[0102] In some embodiments, the two devices can negotiate and determine the GO end and the GC end based on preset rules. For example, the preset rules may include: presetting a large-screen device as the GO, or presetting a terminal device that can support more functions as the GO. The embodiments of this application do not specifically limit this. For example, in the application scenario of multi-screen collaboration, a personal computer (PC) or tablet computer is generally used as the GO; in the application scenario of mirror projection, a large-screen device is generally used as the GO; in the application scenario of file sharing, the sending end is generally used as the GO. The embodiments of this application do not specifically limit this.

[0103] This application takes the first terminal device as a GO device and the second terminal device as a GC device as an example to illustrate the following process.

[0104] S602: Determine whether the first terminal device is connected to the wireless access point. If yes, proceed to S603; if no, proceed to S607.

[0105] It can be understood that in the embodiment of the present application, when the first terminal device and the second terminal device establish a P2P connection channel, it is first necessary to determine whether the first terminal device has accessed the wireless network, for example, by connecting to a wireless router to access the wireless network. If the first terminal device has accessed the wireless network, then go to S603 to determine whether the first communication channel connecting the first terminal device to the wireless access point is a DFS channel; if the first terminal device is not connected to the wireless access point, then go to S607 to determine whether the second terminal device has accessed the wireless network by connecting to a wireless router.

[0106] In some embodiments, if the first terminal device has established a communication connection with the wireless router through a channel, if the first terminal device and the second terminal device establish P2P communication based on another channel, the first terminal device needs to switch between different channels. Figure 2B The time-sharing switching scenario shown in the figure takes a long time to switch, resulting in a decrease in data transmission capacity during P2P communication, causing freezes, timeouts, and other phenomena, affecting the user experience.

[0107] S603: Determine whether the first communication channel between the first terminal device and the wireless access point is DFS. If yes, proceed to S605; if no, proceed to S604.

[0108] It can be understood that in the embodiment of the present application, after determining that the first terminal device accesses the wireless network, the first terminal device system needs to determine whether the first terminal device is connected to the DFS channel. If the first terminal device accesses the wireless network by connecting to any channel in the DFS channel, then go to S605 to determine whether the electronic device chip supports the DFS channel to create P2P communication; if the first terminal device is not connected to the DFS channel, that is, the first terminal device accesses the wireless network through any other non-DFS channel, then go to S604 to establish the P2P channel on the first terminal device channel.

[0109] S604: A P2P channel is established on the first terminal channel.

[0110] It can be understood that in the embodiment of the present application, after the first terminal device system determines that the first terminal device accesses the wireless network through a non-DFS channel, the first terminal device channel is added to the P2P channel list that is optional for the first terminal device and the second terminal device, and the P2P channel is established on the STA communication channel of the first terminal device.

[0111] In this way, the P2P channel and STA channel of the first terminal device are of the same frequency and channel, which avoids the time-sharing switching of the first terminal device between different channels, and effectively improves the P2P communication performance and user experience.

[0112] S605: Determine whether the chips of the first terminal device and the second terminal device support the DFS channel to create P2P communication. If yes, proceed to S606; if no, proceed to S607.

[0113] It can be understood that in the embodiment of the present application, after determining that the first terminal device has established a connection with the wireless router through any channel in the DFS channel, it is necessary to judge whether the electronic device chips of the first terminal device and the second terminal device support the creation of P2P communication on the DFS channel. If supported, go to S606 to establish the P2P channel on the DFS channel of the first terminal device; if not supported, go to S607 to determine whether the second terminal device is connected to the wireless network. In some embodiments, the chips of some terminal devices support the creation of P2P communication on the DFS channel, such as the software architecture corresponding to the chip of a mobile phone or a tablet, for example, the framework layer (Framework, FWK) of the terminal device can be configured with corresponding programs or functions to support the creation of P2P communication on the DFS channel. The embodiment of the present application does not limit this.

[0114] S606: The P2P channel is established on the DFS channel of the first terminal.

[0116] In this way, the P2P channel and STA channel of at least one of the first terminal device and the second terminal device are of the same frequency and channel, which effectively reduces the scenario of time-sharing switching of terminal devices between different channels and improves P2P communication performance and user experience.

[0117] S607: Determine whether the second terminal device is connected to the wireless access point. If yes, proceed to S608; if no, proceed to S612.

[0118] It can be understood that in the embodiment of the present application, when it is determined that the first terminal device is not connected to the wireless network; or when it is determined that the first terminal device establishes a connection with the wireless router through any channel in the DFS channel, but the electronic device chip of the first terminal device or the second terminal device does not support the creation of P2P communication on the DFS channel, it is necessary to judge whether the second terminal device has been connected to the wireless network, for example, by connecting to the wireless router to access the wireless network. If the second terminal device has been connected to the wireless network, go to S608 to determine whether the second terminal device is connected to the DFS channel; if the second terminal device is not connected to the wireless network, go to S612, and the P2P channel is established on channel 149.

[0119] S608: Determine whether the second communication channel through which the second terminal device is connected to the wireless access point is a DFS channel. If yes, proceed to S609; if no, proceed to S611.

[0120] It can be understood that in the embodiment of the present application, after determining that the second terminal device accesses the wireless network, the first terminal device needs to determine whether the second terminal device is connected to the DFS channel. If the second terminal device accesses the wireless network by connecting to any channel in the DFS channel, then go to S609 to determine whether the electronic device chip supports the DFS channel to create P2P communication; if the second terminal device is not connected to the DFS channel, that is, the second terminal device accesses the wireless network through any other non-DFS channel, then go to S611 to establish the P2P channel on the second terminal device channel.

[0121] S609: Determine whether the chips of the first terminal device and the second terminal device support the DFS channel to create P2P communication. If yes, proceed to S610; if no, proceed to S612.

[0122] It can be understood that in the embodiment of the present application, after determining that the second terminal device has established a connection with the wireless router through any channel in the DFS channel, it is necessary to judge whether the electronic device chips of the first terminal device and the second terminal device support the creation of P2P communication on the DFS channel. If supported, go to S610 to establish the P2P channel on the DFS channel of the second terminal device; if not supported, go to S612 to establish the P2P channel on any other non-DFS channel (for example, the 149 channel configured by default in the system, etc.). In some embodiments, the chips of some terminal devices support the creation of P2P communication on the DFS channel, and the embodiment of the present application does not limit this.

[0123] S610: A P2P channel is established on the DFS channel of the second terminal.

The DFS channel of the second terminal device can be added to the P2P channel list, and the P2P channel can be established on the DFS channel of the second terminal device.

[0125] S611: A P2P channel is established on the second terminal channel.

[0126] It can be understood that in an embodiment of the present application, when the first terminal device system determines that the first terminal device is not connected to the wireless network, and at the same time determines that the second terminal device is connected to the wireless network through a non-DFS channel, the second terminal device channel can be added to the P2P channel list optional for GO and GC, and the P2P channel can be established on the STA communication channel of the second terminal device.

[0127] In some embodiments, when the first terminal device system determines that the first terminal device establishes a connection with the wireless router through any channel in the DFS channel, but the electronic device chip of the first terminal device or the second terminal device does not support the creation of P2P communication on the DFS channel, and the first terminal device determines that the second terminal device accesses the wireless network through a non-DFS channel, the second terminal device channel can be added to the P2P channel list optional for GO and GC, and the P2P channel can be established on the STA communication channel of the second terminal device.

[0128] S612: The P2P channel is established on channel 149.

[0129] It can be understood that in the embodiment of the present application, when it is determined that neither the first terminal device nor the second terminal device is connected to the wireless access point, the P2P channel can be established on any other channel (for example, channel 149 configured by system default), and the embodiment of the present application does not limit this.

[0130] In some embodiments, if it is determined that the first terminal device and the second terminal device both establish a connection with the wireless router through any channel in the DFS channel, but the electronic device chip of the first terminal device or the second terminal device does not support the creation of P2P communication on the DFS channel, the P2P channel can be established on any other channel (for example, channel 149 configured by default in the system), and the embodiments of the present application are not limited to this.

[0131] In some embodiments, the first terminal device system determines that the first terminal device establishes a connection with the wireless router through any channel in the DFS channel, but the electronic device chip of the first terminal device or the second terminal device does not support the creation of P2P communication on the DFS channel, and at the same time determines that the second terminal device is not connected to the wireless access point, the P2P channel can be established on any other channel (for example, channel 149 configured by default in the system), which is not limited in this embodiment of the present application.

[0133] For ease of description, take the local device as a GO device, the opposite device as a GC device, and the wireless access point as a wireless router as an example. Figure 7 The specific process diagram of establishing a P2P channel in an embodiment of the present application is shown. Specifically, the method includes the following steps:

[0142] S705: Determine whether the chip supports DFS channel creation GO. If yes, proceed to S711; if no, proceed to S706.

[0143] It can be understood that in the embodiment of the present application, after determining that the GO end device has established a connection with the wireless router through any channel in the DFS channel, it is necessary to judge whether the electronic device chip supports the creation of P2P communication on the DFS channel. If it does, go to S711 to establish the P2P channel on the local device, i.e., the GO end device channel; if it does not, go to S706 to determine whether the opposite device is connected to the DFS.

[0144] S706: Determine whether the opposite device is connected to DFS. If yes, proceed to S707; if no, proceed to S710.

[0145] It can be understood that in the embodiment of the present application, when it is determined that the GO end device establishes a connection with the wireless router through any channel in the DFS channel, but the electronic device chip does not support the creation of P2P communication on the DFS channel, it is necessary to judge whether the opposite device, that is, the GC end device, is connected to the DFS channel. If the opposite device is connected to the DFS channel, go to S707 to establish P2P communication on channel 149; if the opposite device is not connected to the DFS channel, go to S710 to create P2P on the opposite device channel.

[0158] It can be understood that in the embodiment of the present application, when it is determined that the GO-end device establishes a connection with the wireless router through any channel in the DFS channel, and the electronic device chip supports the creation of P2P communication on the DFS channel, the DFS channel of the GO end can be added to the P2P channel list, and the P2P channel can be established on the DFS channel of the GO end.
