[0089] The electronic device 100 may include a processor 110, an external memory interface 120, an internal memory 121, a universal serial bus (USB) interface 130, a charging management module 140, a power management module 141, a battery 142, an antenna 1, an antenna 2, a mobile communication module 150, a wireless communication module 160, an audio module 170, a speaker 170A, a receiver 170B, a microphone 170C, an earphone interface 170D, a sensor module 180, a button 190, a motor 191, an indicator 192, a camera 193, a display screen 194, and a subscriber identification module (SIM) card interface 195, etc. The sensor module 180 may include a pressure sensor 180A, a gyroscope sensor 180B, an air pressure sensor 180C, a magnetic sensor 180D, an acceleration sensor 180E, a distance sensor 180F, a proximity light sensor 180G, a fingerprint sensor 180H, a temperature sensor 180J, a touch sensor 180K, an ambient light sensor 180L, a bone conduction sensor 180M, etc.

[0090] It should be understood that the structures illustrated in the embodiments of the present application do not constitute a specific limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may include more or fewer components than shown, or may combine or separate certain components, or arrange the components differently. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0091] The processor 110 may include one or more processing units, for example: the processor 110 may include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU), etc. Among them, different processing units can be independent devices or integrated into one or more processors. Among them, the controller can be the nerve center and command center of the electronic device 100. The controller can generate operation control signals based on instruction opcodes and timing signals to complete the control of instruction fetching and execution.

[0092] Processor 110 may also include a memory for storing instructions and data. In some embodiments, the memory in processor 110 is a cache memory. This memory can store instructions or data that have just been used or are being recycled by processor 110. If processor 110 needs to use the same instruction or data again, it can directly access the memory. This avoids duplicate accesses, reduces processor 110 latency, and thus improves system efficiency.

[0093] The execution of the screenshot method provided in the embodiment of the present application can be controlled by the processor 110 or completed by calling other components, such as calling the processing program of the embodiment of the present application stored in the internal memory 121 to realize the user's screenshot operation and enhance the user experience.

[0094] In some embodiments, the processor 110 may include one or more interfaces.

It can also be used to connect headphones to play audio. This interface can also be used to connect other electronic devices, such as augmented reality devices.

[0096] It is understood that the interface connection relationship between the modules illustrated in the embodiments of the present application is merely an illustrative illustration and does not constitute a structural limitation on the electronic device 100.

[0097] The wireless communication function of the electronic device 100 can be implemented through the antenna 1, the antenna 2, the mobile communication module 150, the wireless communication module 160, the modem processor and the baseband processor.

[0098] Antenna 1 and Antenna 2 are used to transmit and receive electromagnetic wave signals. Each antenna in electronic device 100 can be used to cover a single or multiple communication frequency bands. Different antennas can also be reused to improve antenna utilization. For example, antenna 1 can be reused as a diversity antenna for a wireless local area network. In other embodiments, the antennas can be used in conjunction with a tuning switch.

[0099] The mobile communication module 150 can provide solutions for wireless communications including 2G / 3G / 4G / 5G applied to the electronic device 100. The mobile communication module 150 may include at least one filter, a switch, a power amplifier, a low noise amplifier (LNA), etc. The mobile communication module 150 can receive electromagnetic waves from the antenna 1, and filter, amplify, and process the received electromagnetic waves, and transmit them to the modulation and demodulation processor for demodulation. The mobile communication module 150 can also amplify the signal modulated by the modulation and demodulation processor, and convert it into electromagnetic waves for radiation through the antenna 1. In some embodiments, at least some of the functional modules of the mobile communication module 150 can be set in the processor 110. In some embodiments, at least some of the functional modules of the mobile communication module 150 can be set in the same device as at least some of the modules of the processor 110.

[0100] The modem processor may include a modulator and a demodulator. The modulator is used to modulate the low-frequency baseband signal to be transmitted into a medium-high frequency signal. The demodulator is used to demodulate the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After being processed by the baseband processor, the low-frequency baseband signal is passed to the application processor. The application processor outputs a sound signal through an audio device (not limited to the speaker 170A, the receiver 170B, etc.) or displays an image or video through the display screen 194. In some embodiments, the modem processor may be an independent device. In other embodiments, the modem processor may be independent of the processor 110 and be set in the same device as the mobile communication module 150 or other functional modules.

[0101] The wireless communication module 160 can provide wireless communication solutions including wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared (IR), etc., which are applied to the electronic device 100. The wireless communication module 160 can be one or more devices integrating at least one communication processing module. The wireless communication module 160 receives electromagnetic waves via the antenna 2, frequency modulates and filters the electromagnetic wave signals, and sends the processed signals to the processor 110. The wireless communication module 160 can also receive the signal to be sent from the processor 110, frequency modulate it, amplify it, and convert it into electromagnetic waves for radiation through the antenna 2.

[0102] In some embodiments, the antenna 1 of the electronic device 100 is coupled to the mobile communication module 150, and the antenna 2 is coupled to the wireless communication module 160, so that the electronic device 100 can communicate with a network and other devices through wireless communication technologies.

[0103] Electronic device 100 implements display functionality through a GPU, display screen 194, and an application processor. A GPU is a microprocessor for image processing that connects display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. Processor 110 may include one or more GPUs that execute program instructions to generate or modify display information.

[0104] Display screen 194 is used to display images, videos, and the like. Display screen 194 includes a display panel. The display panel can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a MiniLED, a MicroLED, a Micro-oLed, or a quantum dot light-emitting diode (QLED).

[0105] The electronic device 100 can implement a shooting function through an ISP, a camera 193, a video codec, a GPU, a display screen 194, and an application processor.

[0106] The ISP processes data fed back by camera 193. For example, when taking a photo, the shutter is opened, and light is transmitted through the lens to the camera's photosensitive element. The light signal is converted into an electrical signal, which is then passed to the ISP for processing and converted into a visible image. The ISP can also perform algorithmic optimization on image noise, brightness, and skin tone. It can also optimize parameters such as exposure and color temperature of the captured scene. In some embodiments, the ISP can be located within camera 193.

[0107] The camera 193 is used to capture still images or videos. The object generates an optical image through the lens and projects it onto the photosensitive element. The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the light signal into an electrical signal, and then passes the electrical signal to the ISP for conversion into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV or other format. In some embodiments, the electronic device 100 may include 1 or N cameras 193, where N is a positive integer greater than 1.

[0108] The digital signal processor is used to process digital signals. In addition to processing digital image signals, it can also process other digital signals. For example, when the electronic device 100 selects a frequency point, the digital signal processor is used to perform Fourier transform on the frequency point energy.

[0109] Video codecs are used to compress or decompress digital video. Electronic device 100 may support one or more video codecs. This allows electronic device 100 to play or record videos in various encoding formats, such as Moving Picture Experts Group (MPEG) 1, MPEG2, MPEG3, and MPEG4.

[0110] The NPU is a neural network (NN) computing processor. Drawing on the structure of biological neural networks, such as the transmission patterns between neurons in the human brain, it rapidly processes input information and can continuously self-learn. The NPU can enable intelligent cognitive applications in electronic device 100, such as image recognition, face recognition, speech recognition, and text comprehension.

[0111] The external memory interface 120 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the electronic device 100. The external memory card communicates with the processor 110 via the external memory interface 120 to implement data storage functions. For example, files such as music and videos can be stored on the external memory card.

[0112] The internal memory 121 can be used to store computer executable program codes, which include instructions. The internal memory 121 may include a program storage area and a data storage area. Among them, the program storage area may store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc. The data storage area may store data created during the use of the electronic device 100 (such as audio data, a phone book, etc.), etc. In addition, the internal memory 121 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, a universal flash storage (UFS), etc. The processor 110 executes various functional applications and data processing of the electronic device 100 by running instructions stored in the internal memory 121 and / or instructions stored in a memory provided in the processor.

[0113] The electronic device 100 can implement audio functions such as music playback and recording through the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the headphone jack 170D, and the application processor.

[0114] The touch sensor 180K is also called a "touch panel." The touch sensor 180K can be disposed on the display screen 194. The touch sensor 180K and the display screen 194 form a touch screen, also called a "touch screen." The touch sensor 180K is used to detect touch operations applied thereto or in the vicinity thereof. The touch sensor can transmit the detected touch operations to the application processor to determine the type of touch event. Visual output related to the touch operations can be provided via the display screen 194. In other embodiments, the touch sensor 180K can also be disposed on the surface of the electronic device 100, in a location different from that of the display screen 194.

[0115] In the embodiment of the present application, the user's touch screen data can be obtained through the touch sensor 180K, and the touch screen data can be sent to the processor 110 for processing.

[0116] The buttons 190 include a power button, a volume button, and the like. The buttons 190 may be mechanical buttons or touch buttons. The electronic device 100 may receive key inputs and generate key signal inputs related to user settings and function control of the electronic device 100.

[0117] Motor 191 can generate vibration prompts. Motor 191 can be used for incoming call vibration prompts, and can also be used for touch vibration feedback. For example, touch operations acting on different applications (such as taking pictures, audio playback, etc.) can correspond to different vibration feedback effects. For touch operations acting on different areas of the display screen 194, motor 191 can also correspond to different vibration feedback effects. Different application scenarios (for example: time reminders, receiving messages, alarm clocks, games, etc.) can also correspond to different vibration feedback effects. The touch vibration feedback effect can also support customization.

[0118] The indicator 192 may be an indicator light, which may be used to indicate the charging status, power level changes, messages, missed calls, notifications, etc.

[0119] The SIM card interface 195 is used to connect a SIM card. The SIM card can be connected to or disconnected from the electronic device 100 by inserting it into or removing it from the SIM card interface 195. The electronic device 100 can support 1 or N SIM card interfaces, where N is a positive integer greater than 1. The SIM card interface 195 can support Nano SIM cards, Micro SIM cards, SIM cards, and the like. Multiple cards can be inserted into the same SIM card interface 195 at the same time.

[0120] Figure 4 A flowchart of an embodiment of a link establishment method provided in an embodiment of the present application includes:

[0121] In step 401 , the first device 10 and the second device 20 send link-related information to the third device 30 .

[0122] Specifically, when the first device 10 establishes a P2P link with the second device 20 , the first device 10 and the second device 20 may send their respective link-related information to the third device 30 .

[0123] Among them, the link-related information may include information such as the Network Address Translation (NAT) type, operator type, and network card type. Exemplarily, the link-related information of the first device 10 may include information such as the Network Address Translation (NAT) type, operator type, and network card type of the first device 10, and the link-related information of the second device 20 may include information such as the Network Address Translation (NAT) type, operator type, and network card type of the second device 20. Among them, the NAT type may include types such as port-restricted cone and symmetric, the operator type may include types such as China Mobile, China Unicom, and China Telecom, and the network card type may include types such as WIFI and cellular. It will be understood that the above examples are merely illustrative of the above types and do not constitute a limitation on the embodiments of the present application. In some embodiments, more types may be included.

[0124] In step 402 , the third device 30 creates link parameters based on the link-related information of the first device 10 and the second device 20 .

[0125] Specifically, after the third device 30 receives the link-related information sent by the first device 10 and the second device 20, it can create corresponding link parameters based on the link-related information sent by the first device 10 and the second device 20. The link parameters can be used to calculate the total score of the link, so that a P2P link can be established between the first device 10 and the second device 20 based on the total score.

[0126] Referring to Table 1, the link parameters may include the following:

[0127] Table 1

[0128]

[0129] Among them, Ra and Rb belong to NAT type, Rc belongs to operator type, and Rd and Re belong to network card type. In addition, the above link parameters may also have corresponding weight scores. It is understandable that the above weight scores may have preset scores in the initial state (for example, the initial state may be a state where no link is established). For example, referring to Table 2, the weights corresponding to the above parameters may include the following scores:

[0130] Table 2

[0131]

[0132]

[0133] It should be noted that the above-mentioned weight scores are merely exemplary and do not constitute a limitation on the embodiments of the present application. In some embodiments, other preset scores may also be used.

[0134] Step 403: The third device 30 constructs a set of candidate links based on the link parameters.

[0135] Specifically, after the third device 30 obtains the above-mentioned link parameters, it can construct a set of candidate links based on the above-mentioned link parameters and the corresponding preset weights. The set of candidate links can include multiple candidate links, each of which can have a corresponding priority, and the priority can be used to characterize the quality of the candidate link. Exemplarily, the candidate link with the highest priority can be the optimal link, that is, the candidate link with the highest priority can be preferentially selected as the actual link, so that the optimal link can be established between the first device 10 and the second device 20 for communication, thereby improving the communication quality.

[0136] In a specific implementation, the priority of the above-mentioned candidate links can be determined by the above-mentioned link parameters and corresponding weights. For example, the total score of each candidate link can be calculated by the following formula:

[0137] Sum=Ra*Wa+Rb*Wb+Rc*Wc+Rd*Wd+Re*We;

[0138] After calculating the total score Sum of each candidate link, the links can be sorted according to the Sum value. The link with the highest Sum value can be the highest priority, the link with the second highest Sum value can be the second highest priority, and so on. Referring to Table 3, the corresponding relationship between the candidate links and their priorities is as follows:

[0139] Table 3

[0140]

[0141] It is understood that Table 3 only shows some of the links to be selected, and does not constitute a limitation on the embodiments of the present application. Figure 2 In the application scenario shown, the first device 10 has four network cards, and the second device 20 has four network cards. Therefore, there may be 16 links to be selected between the first device 10 and the second device 20.

[0142] In step 404 , the third device 30 determines a first link from the candidate links and establishes the first link between the first device 10 and the second device 20 .

[0143] Specifically, after the third device 30 obtains the above-mentioned set of candidate links, the third device 30 can select the first link (for example, the candidate link with the highest priority) from the above-mentioned set of candidate links as the actual link. Then, a first link is established between the first device 10 and the second device 20 so that the first device 10 and the second device 20 can communicate using the first link. In a specific implementation, the third device 30 can send a link establishment notification to the first device 10 and the second device 20, wherein the link establishment notification includes the path of the above-mentioned first link. When the first device 10 and the second device 20 receive the above-mentioned link establishment notification, the above-mentioned first path can be established between the first device 10 and the second device 20.

[0144] In addition, after the third device 30 establishes the first link, the third device 30 may also update the set of candidate links, for example, by deleting the candidate link corresponding to the first link from the set of candidate links, thereby obtaining a first updated set of candidate links.

[0145] In step 405 , the third device 30 sends the first link path and the first updated candidate link set to the first device 10 .

[0146] Specifically, after the third device 30 updates the aforementioned candidate link set and obtains the first updated candidate link set, it can send the first link path and the first updated candidate link set to the first device 10. This allows the first device 10 to add and delete links based on the aforementioned first link path and the first updated candidate link set, thereby improving communication quality.

[0147] It is understandable that the third device 30 may also send the first link path and the first updated candidate link set to the second device 20. This allows the second device 20 to add and delete links based on the first link path and the first updated candidate link set. The embodiment of the present application does not limit to which device, the first device 10 or the second device 20, the third device 30 sends the first link path and the first updated candidate link set. For ease of explanation, the following description takes the case where the third device 30 sends the first link path and the first updated candidate link set to the first device 10 as an example.

[0148] Step 406: The first device 10 obtains QoS information on the first link, and updates the priority of the link to be selected based on the QoS information.

[0149] Specifically, after the first device 10 receives the first link path and the first updated candidate link set sent by the third device 30, the first device 10 may further obtain QoS information for the first link, where the QoS information may include information such as service type, latency, and bandwidth. The service type may include a latency-sensitive type and a bandwidth-sensitive type. Then, the first device 10 may update the priorities of the candidate links in the first updated candidate link set based on the QoS information.

[0150] In specific implementation, the priorities of the candidate links in the first updated candidate link set may be updated according to the service type.

[0151] Taking bandwidth-sensitive services as an example, when recalculating the total score Sum of each candidate link, the values of the weights Wa, Wb, Wc, Wd, and We can all be updated values. For example, referring to Table 4, the values of the weights Wa, Wb, Wc, Wd, and We are as follows:

[0152] Table 4

[0153]

[0154]

[0155] It is understandable that the above weight update data is only for illustrative purposes and does not constitute a limitation on the embodiments of the present application. In some embodiments, other values may also be used.

[0156] After obtaining a new Sum value through recalculation, the first device 10 may update the priority of each candidate link in the first updated candidate link set based on the new Sum value.

[0157] Taking delay-sensitive services as an example, when recalculating the total score Sum of each candidate link, the values of the weights Wa, Wb, Wc, Wd, and We can all be updated values. The specific update process can be referred to Table 4 and will not be repeated here.

[0158] After obtaining a new Sum value through recalculation, the first device 10 may update the priority of each candidate link in the first updated candidate link set based on the new Sum value.

[0159] In step 407 , the first device 10 obtains the service status, determines the second link based on the service status, establishes the second link with the second device 20 , and communicates with the second device 20 using the first link and the second link.

[0160] Specifically, the service state may include an initial state, an unsatisfied state, a matched state, and an overflow state. Figure 5 Figure 1 is a service status diagram. The initial state can be used to represent the state before the link is established; the unsatisfied state can be used to represent that the current link's capabilities cannot meet service requirements. For example, assuming that the current service is a delay-sensitive service, if the delay of the current link cannot meet the delay requirement of the delay-sensitive service, then the current link's capabilities cannot meet service requirements. Alternatively, assuming that the current service is a bandwidth-sensitive service, if the bandwidth of the current link cannot meet the bandwidth requirement of the bandwidth-sensitive service, then the current link's capabilities cannot meet service requirements. The matched state can be used to represent that the current link's capabilities match service requirements; the overflow state can be used to represent that the current link's capabilities exceed service requirements.

[0161] Typically, factors affecting P2P link quality include: NAT type combination, network interface quality (NIC) air interface, carrier combination, NIC combination, and link QoS information. The NAT type combination factor can correspond to link parameters Ra and Rb, the carrier combination factor can correspond to link parameter Rc, the NIC combination factor can correspond to link parameter Rd, and the link QoS information factor can correspond to link parameters such as latency or bandwidth. NIC air interface quality can correspond to the NIC ID.

[0162] In a specific implementation, a service state can be set for the first device 10. When the first device 10 is in the initial state, the NAT type combination and the network card air interface quality have a greater impact. Therefore, the two link parameters Ra and Rb can be given priority consideration, as well as whether to shut down the corresponding network card. For example, the weight scores of the two link parameters Ra and Rb can be increased, and when the air interface quality of any network card is poor, the network card can be shut down, thereby reducing the number of links to be selected. Then, the priority of the links to be selected can be updated based on the above-mentioned NAT type combination and network card air interface quality factors.

[0163] When the first device 10 is in an unsatisfied state, the operator combination factor and the link QoS information factor have a greater impact. At this time, the link parameter Rc and link parameters such as delay or bandwidth can be considered in particular. For example, the weight score of the link parameter Rc and link parameters such as delay or bandwidth can be increased. It can be understood that the link QoS information factor can correspond to link parameters such as delay or bandwidth, and the link parameters such as delay or bandwidth can be used to calculate the total score of the established link, thereby allowing the established link to be reordered. In other words, the link QoS information factor is not applicable to the evaluation of the link to be selected, but only to the evaluation of the established link. Since only one P2P link (for example, the first link) is currently established, when the first device 10 is in an unsatisfied state, only the priority of the link to be selected is updated, and the priority of the established link is not updated.

[0164] After the first device 10 updates the priorities of the candidate links in the first updated candidate link set, a second updated candidate link set is obtained. The first device 10 can then select the highest-priority candidate link in the second updated candidate link set as the second link and establish the second link with the second device 20. This allows the first device 10 to communicate with the second device 20 using both the first and second links simultaneously, thereby ensuring service requirements.

[0165] It should be noted that, when the highest priority candidate link in the second updated candidate link set becomes the second link, the candidate link corresponding to the second link can be deleted from the second updated candidate link set, thereby obtaining a third updated candidate link set.

[0166] When the first device 10 is in a matching state or overflow state, the network card combination factor and the link QoS information factor have a greater impact. At this time, the link parameter Rc and link parameters such as latency or bandwidth can be given priority consideration. For example, the weight score of the link parameter Rd and link parameters such as latency or bandwidth can be increased. In a specific implementation, the overflow state can be when the current capacity of the link exceeds the service demand by 20%. It will be understood that the above ratio is only an example and does not constitute a limitation of the embodiments of the present application. In some embodiments, other ratio values can also be used.

[0167] Step 408: The first device 10 constructs an established link set, and deletes established links in the established link set based on the service status.

[0168] Specifically, after the first device 10 adds the second link, a first established link set may be constructed. The first established link set may include the first link and the second link.

[0169] It is understood that in step 407, if the service requirements are still not met after the first device 10 adds the second link, the highest priority link in the third updated set of candidate links can be used as the third link. The first device 10 can then establish a third link with the second device 20 and simultaneously communicate with the second device 20 using the first link, the second link, and the third link, thereby meeting service requirements and improving communication quality. In other words, the first device 10 can establish multiple links with the second device 20 based on service requirements. For example, in some embodiments, more than three P2P links can be established.

[0170] After multiple P2P links are established between the first device 10 and the second device 20, if the first device 10 is in an overflow state, that is, the links established between the first device 10 and the second device 20 have exceeded the business needs, resulting in a waste of resources. At this time, some of the established links can be deleted, thereby saving resources.

[0171] In a specific implementation, the first device 10 may obtain the delay or bandwidth, and determine the priorities of the established links in the first established link set according to the link parameters, and delete the established link with the lowest priority.

[0172] Taking bandwidth-sensitive services as an example, the first device 10 can obtain the bandwidth of the established link by detecting the established link. Then, the first device 10 calculates the total score Sum of each established link according to the following formula:

[0173] Sum=Ra*Wa+Rb*Wb+Rc*Wc+Rd*Wd+Re*We+(Bcur-Bmin) / (Bmin*Wf);

[0174] Where Bcur is the bandwidth of any of the established links, and Bmin is the minimum bandwidth among all established links. Wf is the weight corresponding to Bmin. For example, when the bandwidth of any established link is 10% greater than the minimum bandwidth, the value of Wf may be increased. It should be understood that the above ratios are merely illustrative and do not constitute limitations on the embodiments of this application. In some embodiments, other ratios may be used.

[0175] Taking a delay-sensitive service as an example, the first device 10 can obtain the delay of the established link by detecting the established link. Then, the first device 10 calculates the total score Sum of each established link according to the following formula:

[0176] Sum=Ra*Wa+Rb*Wb+Rc*Wc+Rd*Wd+Re*We+(Tmax-Tcur) / (Tmax*Wg);

[0177] Where Tmax is the maximum delay among all established links, and Tcur is the delay of any of the established links. For example, when the delay of any established link is 10% lower than the maximum delay, the value of Wg may be increased. It should be understood that the above ratios are merely illustrative and do not constitute a limitation on the embodiments of the present application. In some embodiments, other ratios may be used.

[0178] It should be noted that after deleting any established link, if the remaining established links still exceed the service requirements, the lowest-priority established link among the remaining established links can be further deleted until the remaining established links meet the service requirements. The deleted established link can be added back to the above-mentioned set of candidate links for selection the next time a new link is created.
