The ISP is configured to process the data returned by the camera 193. For example, during photographing, the shutter button is pressed and light is transmitted to the photosensitive element of the camera through the lens. The optical signal is converted into an electrical signal. The photosensitive element of the camera transmits an electrical signal to the ISP for processing to convert the electrical signal into an image visible to the naked eye. The ISP can further optimize the noise, brightness, and skin tone of an image using algorithms. ISP can further optimize parameters such as exposure and scene color temperature. In some embodiments, the ISP may be located in chamber 193.

Camera 193 is configured to capture a still image or video. An optical image of an object is created using a lens and projected onto a photosensitive element. The photosensitive element can be a charge coupled device (CCD) or a phototransistor made of a complementary metal-oxide semiconductor (CMOS). The photosensitive element converts the optical signal into an electrical signal, and then transmits the electrical signal to the ISP to convert it into a digital image signal. The ISP sends the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard format such as RGB or YUV. In some embodiments, electronic device 100 may include one or more cameras 193.

The pressure sensor 180A is configured to sense the pressure signal and convert the pressure signal into an electrical signal. In some embodiments, pressure sensor 180A may be located on display screen 194. There are many types of pressure sensors 180A, such as a resistive pressure sensor, an inductive pressure sensor, and a capacitive pressure sensor. The capacitive pressure sensor may include at least two parallel plates of conductive materials. When a force is applied to the pressure sensor 180A, the capacitance between the electrodes changes. The electronic device 100 determines the pressure intensity based on the capacitance change. When a touch operation is performed on the display screen 194, the electronic device 100 determines the force of the touch operation using the pressure sensor 180A. The electronic device 100 may also calculate the touch position based on the detection signal of the pressure sensor 180A. In some embodiments, touch operations that apply to the same touch position but have a different touch operation force may correspond to different operating instructions. For example, when a touch operation whose operation force is less than the first pressure threshold is applied to the SMS message application icon, an instruction to view the SMS message is executed; when a touch operation whose operation force is greater than or equal to the first pressure threshold value is applied to the SMS message application icon, an instruction is executed to create a new SMS message.

In some embodiments, the angular velocity of the electronic device 100 about three axes (namely, the x, y, and z axes) can be determined using the gyro sensor 180B. The gyro sensor 180B can be used to stabilize the image during photography. For example, when the shutter button is pressed, the gyro sensor 180B detects the shake angle of the electronic device 100 and calculates, based on the angle, the distance that the lens module must compensate for the lens to move backward to counteract the shake of the terminal device 100 to realize image stabilization. The gyro sensor 180B can be further used for navigation scenarios and somatosensory play.

The temperature sensor 180J is configured to detect the temperature. In some embodiments, the electronic device 100 executes the temperature processing policy using the temperature detected by the temperature sensor 180J. For example, when the temperature reported by the temperature sensor 180J exceeds a threshold, the electronic device 100 reduces the processor performance near the temperature sensor 180J to reduce power consumption and implement thermal protection. In some other embodiments, when the temperature is below another threshold, the electronic device 100 heats the battery 142 to avoid abnormal shutdown of the electronic device 100 caused by low temperature. In some other embodiments, when the temperature is lower than another threshold, the electronic device 100 increases the output voltage of the battery 142 to avoid abnormal shutdown caused by the low temperature.

The touch sensor 180K may be disposed on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, also referred to as a "touch screen". The touch sensor 180K is configured to detect a touch operation being performed on or near the touch sensor 180K. The touch sensor may communicate the detected touch operation to the application processor to determine the type of touch event and may provide a visual output associated with the touch operation via the display screen 194. In some other embodiments, the touch sensor 180K may alternatively be placed on the surface of the electronic device 100, that is, at a location other than the position of the display screen 194.

This allows multiple Wi-Fi devices to form a peer to peer network (P2P network) to communicate with each other without an access point (AP). One station (STA) that can function as a normal AP is called a group owner (GO), and another STA can be called a group client (GC). A GC can connect to a GO just like connecting to an AP. One STA can play the role of GO (that is, act as an AP) and other STAs play the role of GC.

To build a P2P network, firstly, an electronic device must find another electronic device by scanning using the P2P protocol, and such a process is called the discovery phase; and upon discovery, a P2P connection may be initiated.

After detecting the user's action on the touch panel, the mobile phone can control the cursor on the smart TV to move. In this case, a mobile phone is equivalent to a mouse.

Before describing the specific process of wireless projection from a mobile phone to a smart TV, P2P Wi-Fi technology will first be described with reference to FIG. 7. For example, in FIG. Figure 7 shows a one-to-one process (P2P device 1 and P2P device 2), i.e. one GO to one GC. Alternatively, this process could be a one-to-many process, i.e. one GO to many GCs.

S701. P2P device 1 enters the scan phase.

For example, as shown in FIG. 3(b), upon detecting a touch operation of the control 302 by the user, the mobile phone enters the scanning phase.

For example, as shown in FIG. 4(e), upon detecting the touch operation of the user control 406, the mobile phone enters the scanning phase.

Both P2P device 1 and P2P device 2 can send a probe request frame during the scan phase, and P2P device 1 and P2P device 2 can send a probe request frame in all bands they support, in searches for information about all nearby devices or networks. When the P2P device 1 has transmitted the probe request frame over the channel and received the probe response frame, it means that the P2P device 1 has discovered the receiver device, and the P2P device 1 can display information about the discovered device to the user through the display screen.

For example, as shown in FIG. 7, if the P2P device 1 only supports the 2.4GHz band, the P2P device 1 may transmit a probe request frame on each of channels 1-13.

For example, as shown in FIG. 7, if the P2P device 1 supports the 2.4GHz band and the 5GHz band, the P2P device 1 may transmit a probe request frame on each of channels 1-165.

It should be understood that channels 1-165 may not be continuous channels, and channels with different channel numbers may be in the same band or may be in different bands.

It should also be understood that the 2.4 GHz and 5 GHz bands are taken as examples for describing embodiments of the present application, and various other bands such as the 5 GHz and 60 GHz bands may also be used. The difference between the 2.4GHz band and the 5GHz band is that the 2.4GHz band and the 5GHz band are two different frequency spectrums used by electronic devices to transmit RF signals. The 2.4GHz and 5GHz bands cover different bands. The 2.4 GHz signal range is from 2.4 GHz to 2.4835 GHz with a total bandwidth of 83.5 MHz; and the frequency range of 5 GHz signals is from 4.910 GHz to 5.875 GHz with a total bandwidth of 965 MHz.

For example, 13 channels from channel 1 to channel 13 can be 2.4 GHz channels, while channel 36, channel 40, channel 44, channel 48, channel 53, channel 60, channel 120, channel 128, channel 149, channel 153, channel 157, channel 161, channel 165, etc. may be 5 GHz channels.

It should be understood that if the P2P device 1 only supports the 2.4 GHz band, during the scan phase, the P2P device 1 can only send a probe request frame on each of the 13 channels from channel 1 to channel 13; if the P2P device 1 supports the 2.4GHz band and the 5GHz band, the P2P device 1 may transmit a probe request frame on each of the above channels 1-165.

It should also be understood that after the P2P device 2 is turned on or after the user detects a Miracast app tap operation, the P2P device 2 may alternatively go through the scanning phase first. In this embodiment of the present application, as an example of a large screen device, the P2P device 2 may enter the listening phase after the scanning phase is completed. Alternatively, when the P2P device 2 is a large screen device, the scanning phase can be skipped and the P2P device 2 starts to enter the listening phase for continuous listening when it is turned on or after the user touches the corresponding P2P application. This is because a large screen device may not project its interface to another device, and only another device may project its interface to a large screen device. Thus, a large screen device may not need to detect other devices and may not go through the scanning phase, but only go through the listening phase.

It should also be understood that if, during the scan phase, P2P device 1 does not discover a destination device, or P2P device 1 discovers a destination device but does not detect a user listening operation on the destination device, P2P device 1 may enter the discovery phase. after completion of the scanning phase, where the P2P-discovery-device 1 phase may include a listening phase (listen) and a search phase (search).

S702. P2P device 1 enters the listening phase.

For the listen phase, the P2P protocol also defines the duration that the device is in the listen phase, which is N times greater than 100 TUs, where N is a random positive integer. For example, N can be any of the integers 1, 2, and 3. The reason N is a random positive integer is to prevent P2P device 1 and P2P device 2 from entering the listening phase and entering the listening phase at the same time. searching at the same time after waiting for the same time. If so, both devices cannot process the probe request frame from each other.

It should be understood that before the scanning phase, each of P2P device 1 and P2P device 2 may determine a channel to listen on. As shown in FIG. 7, the channel on which the P2P device 1 listens is channel 1, and the channel on which the P2P device 2 listens is channel 6.

S703. P2P device 1 enters the scanning phase to search for P2P devices, and P2P device 2 continues to remain in the listening phase.

For example, as shown in FIG. 7, if the P2P device 1 only supports the 2.4GHz band, the P2P device 1 can only transmit the probe request frame on channel 1, channel 6, and channel 11 after entering the scanning phase. When P2P device 1 transmits a probe request frame on channel 6, since P2P device 2 is currently listening on channel 6, after P2P device 2 has received the probe request frame on channel 6, P2P device 2 may send probe response frame to P2P device 1. After receiving the probe response frame, P2P device 1 can display information about P2P device 2 to the user, as shown in FIG. 3(d) and FIG. 4(d). After the user detects the P2P device 2 listening operation, P2P device 1 can connect to P2P device 2.

For example, if the P2P device 1 supports the 2.4GHz band and the 5GHz band, the P2P device may separately transmit a probe request frame on channel 1, channel 6, and channel 36 after entering the search phase.

It should be understood that in this embodiment of the present application, a probe request frame transmitted by one device can only be received by another device when the two devices are in the same range. Also, a probe request frame sent by one device can only be received by another device if the two devices are in the same range and have channels with the same channel number.

It should also be understood that, in addition to the same band, channels with the same channel number have the same center frequency or operating range.

It should also be understood that after P2P device 1 detects P2P device 2, the next step is to tap to connect. The first step of tapping to connect is to determine their respective roles, i.e. which device is the GO and which is the GC. In P2P Wi-Fi technology, roles can be defined through interaction using additional action frames. Reference may be made to the existing P2P Wi-Fi technology regarding the process, and details are not described here for the sake of brevity.

For the existing P2P Wi-Fi technology, if the current large-screen device is connected to the 5GHz channel via Wi-Fi, the electronic device that only supports 2.4GHz will not be able to detect the large-screen device.

For example, Table 1 shows a P2P discovery scenario for a mobile phone that supports both 2.4 and 5 GHz bands and a mobile phone that only supports 2.4 GHz.

Table 1

For example, Table 2 shows responses from a large screen device when a 2.4 GHz mobile phone transmits a packet on each of channels 1, 6, 8, and 11.

table 2

For example, Table 3 shows responses from a large screen device when a 2.4 GHz mobile phone transmits a packet on each of channels 1 and 6.

Table 3

It should be understood that Tables 1-3 above show that a mobile phone can only receive a probe request response from a large screen device when it transmits a probe request frame on the same channel number and in the same range as and a large screen device channel. Thus, if the mobile phone only supports the lower band while the large screen device is connected to the high band, the mobile phone cannot detect the large screen device, so that the user cannot project the mobile phone information into the large screen device in real life. time, which affects the user experience.

An embodiment of the present application provides a communication method to enable any P2P-enabled electronic device to realize real-time screen projection and enable users to experience the convenience and speed of P2P real-time screen projection.

The detailed information transfer process between the first electronic device and the second electronic device in the embodiment of the present application is described below.

In FIG. 8 is a schematic flow diagram of a method 800 for transmitting information according to an embodiment of the present application. As shown in FIG. 8, method 800 includes the following steps.

S801. The first electronic device detects the user's first operation.

For example, the first operation may be an operation for the user to listen to the P2P application.

For example, as shown in FIG. 3(b), the first operation is the operation of touching the control 302 by the user.

For example, as shown in FIG. 4(e), the first operation is the operation of touching the user control 406 .

In one embodiment, the P2P application includes a Miracast application and a Wi-Fi Direct application. The control 302 may be a Miracast application entry, and the control 406 may be a Wi-Fi Direct application entry.

S802. The first electronic device starts scanning P2P devices in response to the first operation.

For example, for the P2P device 1 shown in FIG. 7, after the user touches the Miracast application or the Wi-Fi direct application, the P2P device 1 starts to sequentially enter a scanning phase, a listening phase, and a searching phase.

S803. The second electronic device detects the user's second operation.

S804. The second electronic device starts P2P listening in response to the second operation.

It should be understood that in this embodiment of the present application, it is contemplated that the first electronic device may be a source device and the second electronic device may be a sink device, such as the smart TV shown in FIG. 3(e)-1 and the smart TV shown in FIG. 4(h). When the smart TV is turned on, the smart TV can automatically launch the P2P application, or when the smart TV detects a user tap operation of the P2P application, the smart TV launches the P2P application.

It should also be understood that after the smart TV launches the P2P application, it may sequentially enter the scanning phase and the listening phase, such as the P2P device 2 shown in FIG. 7.

It should be understood that there is actually no sequential order in which steps S801-S802 and S803-S804 are performed.

S805. The first electronic device detects the second electronic device.

In one embodiment, the first electronic device supports the first band, the second electronic device is connected to the second band, and the bandwidth covered by the first band is less than the bandwidth covered by the second band.

The second electronic device may perform listening in a time division manner in the first and second bands.

For example, the first electronic device is a mobile phone and the second electronic device is a smart TV. The mobile phone only supports the 2.4GHz band, while the smart TV connects to a channel (such as channel 36) in the 5GHz band via Wi-Fi. The smart TV remains and listens on channel 36, and therefore, when the mobile phone sends a probe request frame to the smart TV on each of channels 1-13 during the scan phase, the smart TV does not return a probe response to the mobile phone. Alternatively, the smart TV does not return a probe response to the mobile when the mobile sends a probe request frame to the smart TV on channel 1, channel 6, or channel 11 during the scan phase.

In this embodiment of the present application, for a large screen device connected to a channel (eg, channel 36) in the 5G band via Wi-Fi, a time division listening method can be used.

In FIG. 9 is a schematic representation of a time division listening method according to an embodiment of the present application. As shown in FIG. 9, the smart TV can listen at T intervals. The smart TV listens on a channel (for example, on channel 36) of the second band for a time period T1 at T intervals, and listens on a channel (for example, on any of channel 1, channel 6 and channel 11) of the first range within the time period T2 with a periodicity T, where T1 < T, T2 < T and T1 + T2 = T.

It should be understood that the first band channel may be a social channel. The social channel in the embodiments of the present application may be a channel in the 2.4 GHz band. For example, the social channel is any of channels 1, 6, or 11. Alternatively, the first band channel can be a non-social channel, such as channel 7 or channel 8.

Using the method of the prior art, the smart TV can continuously stay on channel 36 and listen to it at a listening interval, whereby a 2.4GHz-only mobile phone cannot detect the smart TV.

Using the method of this embodiment of the present application, a smart TV connected to a channel in the 5 GHz band via Wi-Fi can perform listening on different channels with the same listening period, so that the smart TV can detect, on a social channel within the listening period, a frame probe request transmitted by the mobile phone, and the smart TV can return a probe response to the mobile phone, thereby ensuring that the mobile phone can detect the smart TV.

In one embodiment, T ₁ > T ₂ .

With T ₁ > T ₂ , it can be guaranteed that within one detection period, the duration that the smart TV stays on the channel and listens on it in the 5 GHz band exceeds the duration that the smart TV stays on the social channel and listens by him. This can ensure that the smart TV can detect the social channel probe request frame without affecting the Wi-Fi packet exchange between the smart TV and the AP, so that it does not affect the use of the Internet access function of the smart TV by the user (for example, to watch movies and watching several films in a row).

It should be understood that the above embodiment is described in terms of a smart TV connected to a channel in the 5GHz band (for example, channel 36) via Wi-Fi, and the channel on which the smart TV listens may be the same as the channel through which the smart TV connects to the access point. When Wi-Fi (or Bluetooth) is enabled to connect to an AP, the smart TV can detect one or more APs. In this case, the smart TV can learn the channel of each of one or more access points (AP channels can be the same or different). When a smart TV is connected to an AP, it can be determined that the smart TV can listen on the channel corresponding to the AP.

It should also be understood that after the smart TV is connected to the AP, it can receive packets transmitted by the AP over Wi-Fi, so that the user can use the smart TV to perform operations such as watching videos, live broadcasting, and browsing the web.

In FIG. 10 is a schematic representation of a time division listening method according to an embodiment of the present application. As shown in FIG. 10, the smart TV can listen at T intervals. The smart TV listens on a channel (for example, channel 36) of the second band for a period T ₃ of time at T intervals, listens on the first channel (for example, channel 1) of the first band in during a period T ₄ of time with a periodicity T and performs listening on the second channel (for example, channel 6) of the first band during a period T ₅ of time with a periodicity T, where T ₃ < T, T ₄ < T, T ₅ < T and T ₃ + T ₄ + T ₅ \u003d T.

It should be understood that the time division listening interval shown in FIG. 10 may be the same or different from the time division listening period shown in FIG. 9, and this is not limited in the present application.

It should also be understood that the first channel of the first band may be a social channel, or may be a non-social channel of the first band, such as channel 7 or channel 8; and the second channel of the first band may be a social channel, or may be a non-social channel in the first band, such as channel 7 or channel 8.

It should be understood that in order to describe the listening method shown in FIG. 10, reference may be made to the above embodiment, and the details are not described here for the sake of brevity.

It should also be understood that the smart TV can listen at intervals T, where the smart TV listens on a channel (for example, channel 36) of the second band for a period of time T6 at intervals T, listens on the first channel (for example, channel 1 ) of the first band during the period T ₇ of time with a periodicity T, listens on the second channel (for example, on channel 6) of the first band during the period T ₈ of time with a periodicity of T and listens on the third channel (for example, on channel 11) of the first range during the period T ₉ time with a frequency T, where T ₆ < T, T ₇ < T, T ₈ < T, T ₉ < T and T ₆ + T ₇ + T ₈ + T ₉ = T.

In one embodiment, the first electronic device supports the first band and the second electronic device is connected to the channel of the first band.

In one embodiment, the first electronic device supports the first band and the second electronic device is connected to the non-social channel of the first band.

For example, the first band is the 2.4 GHz band.

For example, the first electronic device is a mobile phone and the second electronic device is a smart TV. The mobile phone supports the 2.4GHz band, the smart TV is connected to the access point via Wi-Fi, the current channel of the access point is a channel (such as channel 7) in the 2.4GHz band, then the smart TV can connect to and listen to channel 7. Since the smart TV stays on channel 7 and listens on it, when the mobile phone sends a probe request frame to the smart TV on each of channels 1-13 during the scan phase, the smart TV can return a probe response frame to the mobile phone, if the smart TV is listening when the mobile phone is transmitting a probe request frame on channel 7.

However, if the smart TV is not listening when the mobile phone transmits a probe request frame on channel 7, the mobile phone cannot detect the large screen device during the scanning phase. After entering the search phase, the mobile phone can only transmit the probe request frame on the social channel (channel 1, channel 6 and channel 11). Since the smart TV is connected to and listening on channel 7, the smart TV cannot receive the probe request frame sent by the mobile phone. Thus, in this process, the mobile phone can only detect the smart TV during the scanning phase, which can increase the mobile phone's detection time of the large screen device, thereby affecting the user experience.

It should be understood that a mobile phone may perform multiple scans in the process of detecting a large screen device, and each scan may include one scan phase and multiple (eg, 6 to 8) search phases. During each scan, if the mobile phone does not detect the smart TV during the scanning phase, the smart TV may not be detected during the search phase. In this case, the mobile phone can only detect the large screen device during the scanning phase of the next scan.

In this embodiment of the present application, if the smart TV detects that the current AP channel is a non-social channel, the smart TV may alternatively perform time division listening.

In FIG. 11 is a schematic representation of another listening method in a time division manner according to an embodiment of the present application. As shown in FIG. 11, the smart TV listens at T intervals. The smart TV listens on the non-social channel (for example, channel 7) of the first band for a time period T ₁₀ at T intervals, and listens on the social channel (for example, on any of channel 1, channel 6 and channel 11) of the first range within the period T ₁₁ of time with a frequency T, where T ₁₀ < T, T ₁₁ < T and T ₁₀ + T ₁₁ = T.

In one embodiment, T ₁₀ > T ₁₁ .

T ₁₀ > T ₁₁ can ensure that within one detection period, the duration that the smart TV remains on the non-social channel and listens on it in the 2.4 GHz band exceeds the duration that the smart TV remains on the social channel and performs listening on it. This can ensure that the smart TV can detect the social channel probe request frame without affecting the Wi-Fi packet exchange between the smart TV and the AP, so that it does not affect the use of the Internet access function of the smart TV by the user (for example, to watch movies and watching several films in a row).

It should be understood that the time division listening interval shown in FIG. 11 may be the same or different from the time division listening period shown in FIG. 9, and this is not limited in the present application.

For example, in FIG. 12 is a schematic representation of another listening method in a time division manner according to an embodiment of the present application. As shown in FIG. 12, the smart TV can listen at intervals T. The smart TV listens on a non-social channel (for example, channel 7) from the first band for a time period T ₁₂ at intervals T, listens on the first social channel (for example, channel 1 ) from the social channels of the first range during the period T ₁₃ of time with a frequency of T and performs listening on the second social channel (for example, on channel 6) from the social channels of the first range during the period T ₁₄ of time with a frequency of T, where T ₁₂ < T, T ₁₃ < T, T ₁₄ < T and T ₁₂ + T ₁₃ + T ₁₄ = T.

It should be understood that the time division listening method may alternatively be within the same periodicity, perform time division listening on a non-social channel (e.g. channel 7), a first social channel (e.g. channel 1), a second social channel (e.g. , on channel 6) and a third social channel (for example, on channel 11).

In this embodiment of the present application, in the case where the smart TV is connected to the non-social 2.4GHz band, when listening, the smart TV can perform listening on the non-social channel and the social channel in a time-shared manner, which can reduce the time required for the mobile phone to in order to detect the smart TV, reduce the waiting time for the user and improve the user experience.

In one embodiment, the first electronic device supports the first band and the second electronic device is connected to the social channel of the first band.

For example, the first band is the 2.4 GHz band.

For example, the first electronic device is a mobile phone and the second electronic device is a smart TV. The mobile phone supports the 2.4GHz band, the smart TV is connected to the access point via Wi-Fi, the current channel of the access point is a channel (such as social channel 11) in the 2.4GHz band, then you can connect the smart TV and listen to social channel 11. Since the smart TV stays on and listens to channel 11, when the mobile phone sends a probe request frame to the smart TV on each of channels 1-13 during the scanning phase, the smart TV can return a probe response frame to the mobile phone if the smart TV is listening when the mobile phone transmits a probe request frame on channel 11. Alternatively, the mobile phone can send a probe request frame to the smart TV on each of channel 1, channel 6, and channel 11 during the search phase, and the smart TV may return a probe response frame to the mobile phone if the smart TV is listening when the mobile phone transmits a probe request frame on channel 11.

It should be understood that if the smart TV is connected to the access point via Wi-Fi, and the current channel of the access point is channel 11, the mobile phone and the smart TV can be connected and listen on social channel 11, or can be connected and listen on channel 1 or 11. Alternatively, listening in a time division manner may be performed, and the smart TV may perform listening at intervals T. The smart TV listens on a social channel (for example, channel 1) of the first band for a period of time T12 at intervals T and performs listening on the second social channel (for example, on channel 11) from the social channels of the first band during the time period T13 with the periodicity T.

S806. The first electronic device is connected to the second electronic device so that the first electronic device can transmit information to the second electronic device.

For example, as shown in FIG. 3(d), upon detection of the device information listening operation by the user, the mobile phone is connected to the smart TV.

For example, as shown in FIG. 4(g), upon detection of the device information listening operation by the user, the mobile phone is connected to the smart TV.

In the information transmission method according to this embodiment of the present application, the listening method of the second electronic device is changed to allow the first electronic device performing low-band scanning to detect the second electronic device performing high-band listening, so that the first electronic device and the second electronic device can be connected to transfer information.

In FIG. 13 is a schematic representation of a process for establishing a P2P connection between a mobile phone and a large screen device according to an embodiment of the present application. As shown in FIG. 13, the process includes the following steps.

S1301. The mobile phone detects the user's P2P application launch operation.

For example, the mobile phone is a mobile phone that only supports the 2.4GHz band.

It should be understood that P2P applications include the Miracast application and the WLAN direct application.

For example, as shown in FIG. 3(b), the operation is the operation of touching the user control 302 . When the mobile phone detects a touch operation of the user control 302, the mobile phone launches the Miracast application to scan P2P devices.

For example, as shown in FIG. 4(e), the operation is the operation of touching the user control 406 . When the mobile phone detects a touch operation of the user control 406, the mobile phone launches the WLAN direct application to scan P2P devices.

S1302. The mobile phone starts scanning P2P devices in response to the P2P application start operation of the mobile phone.

S1303. A device with a large screen recognizes user actions.

In one embodiment, the user operation detected by the large screen device is the operation of turning on the mobile phone by the user or the operation of tapping by the user of the P2P application.

S1304. The large screen device starts P2P real-time listening in response to the operation.

S1305. If a large screen device is connected to a 5GHz channel via Wi-Fi, the large screen device can perform time division listening in a 5GHz channel and a 2.4GHz channel.

In one embodiment, the listening method of a large screen device may be the listening method shown in FIG. 9 or FIG. 10.

In one embodiment, the channel in the 2.4 GHz band is a social channel, such as channel 1, channel 6, or channel 11.

S1306. If the large screen device is not connected to Wi-Fi, or the large screen device is connected to a 2.4GHz channel via Wi-Fi, the large screen device can listen to the 2.4GHz channel.

In one embodiment, if the large screen device is not connected to Wi-Fi, the large screen device can listen on a social channel (on any of channels 1, 6, or 11).

In one embodiment, if the large screen device is connected to a social channel (any of channels 1, 6, or 11) on the 2.4 GHz band via Wi-Fi, the large screen device can listen on the social channel.

In one embodiment, if the large screen device is connected to a non-social channel (e.g., channel 7 or channel 8) in the 2.4 GHz band via Wi-Fi, the large screen device can perform time division listening on the non-social channel. and social channel.

For example, for the time-shared listening method performed by the large screen device on the non-social channel and the social channel, reference can be made to the listening method shown in FIG. 11 or FIG. 12.

It should be understood that there is actually no sequential order for performing steps S1301-S1302 and S1303-S1306.

S1307. The mobile phone detects a device with a large screen.

For example, if a large screen device is connected to a 5G channel via Wi-Fi, the mobile phone can detect the large screen device over a 2.4G channel.

For example, if a large-screen device is not connected to Wi-Fi, the mobile phone can discover the large-screen device through a social channel.

For example, if a large screen device is connected to a social channel on the 2.4GHz band via Wi-Fi, the mobile phone can detect the large screen device via the social channel.

For example, if a large screen device is connected to a non-social channel in the 2.4GHz band via Wi-Fi, the mobile phone can detect the large screen device through the non-social channel or the social channel.

S1308. Mobile phone and big screen device connect via P2P.

For example, a mobile phone can initiate a P2P channel connection through the Miracast app.

For example, a mobile phone can initiate a P2P channel connection via a WLAN direct application.

S1309. The mobile phone projects an interface onto a large screen device, or the mobile phone transmits information to a large screen device.

With reference to the above embodiment and related drawings, FIG. 14 shows a communication method 1400 according to an embodiment of the present application, and the method 1400 can be applied to a system including a first electronic device and a second electronic device. The first electronic device is connected in the first band and the spectrum width covered by the second band is less than the spectrum width covered by the first band. As shown in FIG. 14, method 1400 may include the following steps.

S1401. The first electronic device listens on the first channel, where the first channel is the channel of the second range.

For example, the first band is 5 GHz and the second band is 2.4 GHz.

In one embodiment, the first channel is a social channel.

In this embodiment of the present application, the first electronic device may perform social listening and the second electronic device may detect the second electronic device during the scan phase or the search phase. This makes it possible to improve the scanning efficiency of the second electronic device, thereby improving the efficiency of information transmission between the first electronic device and the second electronic device.

S1402. The first electronic device receives the request information transmitted by the second electronic device, where the request information is used to request the connection establishment.

For example, the request information is a probe request frame.

S1405. The first electronic device receives information transmitted by the second electronic device.

In this embodiment of the present application, the bandwidth covered by the first band in which the first electronic device is connected is greater than the bandwidth of the second band supported by the second electronic device, and the first electronic device may choose to listen on the channel of the second band while listening. This allows the electronic device that only supports the second band and the electronic device that supports the first band and the second band to detect the second electronic device in real time during scanning, thereby improving the efficiency of information transmission between the first electronic device and the second electronic device.

In some possible implementations, the second electronic device is an electronic device that only supports the second band.

If necessary, the method further includes: performing, by the first electronic device, listening on the second channel, where the second channel is the channel of the first range.

If necessary, the duration of listening performed by the first electronic device on the first channel is equal to the first duration, the duration of listening performed by the first electronic device on the second channel is equal to the second duration, and the first duration is less than the second duration.

In this embodiment of the present application, the listening time performed by the first electronic device on the first band channel is longer than the listening time performed by the first electronic device on the second band channel. This facilitates real-time detection of the first electronic device by scanning the second electronic device without affecting the Internet access function (for example, to watch movies and watch multiple movies in a row) of the second electronic device.

In FIG. 15 shows a schematic flowchart of a communication method 1500 according to an embodiment of the present application, and the method 1500 may be applied to a system including a first electronic device and a second electronic device. The first electronic device is connected in the 2.4 GHz band, where the channel of the AP to which the first electronic device is connected is a non-social channel.

Optionally, the method further includes: performing, by the first electronic device, listening to the non-social channel.

In the method of this embodiment of this application, when the first electronic device is connected to a 2.4 GHz non-social channel, the first electronic device can perform listening in a time-separated manner on the social channel and on the non-social channel, which allows the second electronic device to detect the first electronic device in the time of the scanning phase or the searching phase, which makes it possible to improve the efficiency of information transfer between the first electronic device and the second electronic device.

Optionally, the duration of listening performed by the first electronic device on a social channel is equal to the first duration, the duration of listening performed by the first electronic device on a non-social channel is equal to the second duration, and the first duration is less than the second duration.
