Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method and related apparatus. Background Technology

[0002] In Wi-Fi peer-to-peer (P2P) technology, devices can share media data, enabling applications such as multi-screen collaboration and device sharing. P2P technology defines two roles: the group owner (GO) and the group client (GC). The P2P GO functions similarly to the access point in a traditional Wi-Fi network, while the P2P GC functions similarly to the wireless station in a traditional Wi-Fi network.

[0003] In a traditional P2P group or network, one and only one device acts as the P2P GO (Go-Organizer), while the other devices act as the P2P GC (Collection-Organizer). A P2P connection exists between the P2P GO and the P2P GC, enabling data transmission for P2P services.

[0004] Currently, the P2P connection establishment process mainly involves device negotiation, information transmission, scanning and discovery, and connection procedures. However, during the scanning and discovery process, the P2P GC may not be able to detect the P2P GO, resulting in a long scanning time, which cannot meet the business requirements with high connection duration requirements. Summary of the Invention

[0005] This application provides a communication method and related apparatus. By adjusting the channel scanning strategy in the P2P GC, the frequency of the P2P GO can be quickly determined, enabling the P2P GC and P2P GO to quickly implement P2P services with high connection duration requirements.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0007] In a first aspect, a communication method is provided, applied to a first device, the method comprising:

[0008] Receive a first command sent by the second device, wherein the first command includes the first frequency of the second device;

[0009] In response to the first command, a first channel scan is triggered, and the second frequency of the second device is detected. The scanning duration of the first channel scan is less than or equal to the connection duration for the first device and the second device to achieve peer-to-peer service. The scanning duration of the first channel scan is related to the number of scans and / or the scanning interval optimized in the scanning strategy of the first channel scan.

[0010] A peer-to-peer connection is established between the first device and the second device based on the second frequency. The peer-to-peer connection is used by the first device and the second device to implement peer-to-peer services.

[0011] According to the communication method of this application, the second device sends a first command to the first device, which triggers the first device to scan and discover the second device. After receiving the first command, the first device may be unable to receive or use the first frequency. Therefore, the first device can trigger a first channel scan. Because the number of scans and / or the scan interval in the first channel scan strategy are optimized or adjusted, the scan duration of the first channel scan is less than or equal to the connection duration for the first device and the second device to achieve peer-to-peer service. In other words, the scan duration of the first channel scan is adaptable to the actual requirements of the connection duration for P2P services, especially those with high connection duration requirements. Therefore, the first device can quickly detect the correct frequency, i.e., the second frequency, while meeting the high connection duration requirements of P2P services. Thus, the first device can establish a P2P connection between the first device and the second device based on the second frequency, enabling the first device and the second device to quickly achieve instant P2P service.

[0012] In one possible implementation of the first aspect, triggering a first channel scan upon obtaining a first frequency according to a first command includes: triggering a single-channel scan using the first frequency, and then triggering a full-channel scan; or, triggering a single-channel scan using the first frequency; or, triggering a full-channel scan.

[0013] If the first frequency is not obtained according to the first command, triggering the first channel scan includes: triggering a single channel scan using the third frequency, and then triggering a full channel scan; or, triggering a single channel scan using the third frequency; or, triggering a full channel scan.

[0014] It is evident that the first device may be able to receive and use the first frequency, or it may be able to receive but not use the first frequency, or it may not be able to receive the first frequency at all. Therefore, the first channel scan can accommodate all of the aforementioned scenarios, enabling the first device to quickly obtain the second frequency of the second device. Here, the second frequency is the correct frequency, meaning the first device can discover the second device based on the second frequency. The second frequency can be the same as or different from the first frequency. The third frequency can be a frequency pre-negotiated between the first and second devices, or it can be a default frequency.

[0015] In one possible implementation of the first aspect, the first channel scan includes: single-channel scanning and / or full-channel scanning; the scanning strategy of the first channel scan satisfies at least one of the following:

[0016] The number of scans for a single-channel scan is less than or equal to the first value;

[0017] The interval between single-channel scans is less than or equal to the first duration;

[0018] The interval between single-channel scanning and full-channel scanning is less than or equal to the second duration;

[0019] The interval between full-channel scans is less than or equal to the third duration.

[0020] It can be seen that the first device can adjust at least one of the following: the number of scans and the interval duration of a single-channel scan, the interval duration between a single-channel scan and a full-channel scan, and the interval duration of a full-channel scan.

[0021] If the first device is able to scan and use the first frequency, it can adjust its single-channel scanning strategy to quickly enter full-channel scanning, significantly improving the connection success rate. Similarly, the first device can adjust its full-channel scanning strategy, not only enabling it to quickly enter full-channel scanning and significantly improving the connection success rate, but also allowing it to quickly enter the next full-channel scan.

[0022] If the first device cannot scan the first frequency, or if it can scan and use the first frequency, the first device can adjust its scanning strategy between single-channel scanning and full-channel scanning, enabling it to quickly enter full-channel scanning and significantly improving the connection success rate.

[0023] In summary, the first device can quickly establish a P2P connection between the first device and the second device to meet the needs of P2P services with high connection duration requirements.

[0024] In one possible implementation of the first aspect, the first value is set based on the connection success rate between the first device and other devices.

[0025] In one possible implementation of the first aspect, the first value is less than or equal to 4.

[0026] In one possible implementation of the first aspect, the first duration, the second duration, or the third duration is set according to the capabilities of the wireless fidelity module in the first device.

[0027] In one possible implementation of the first aspect,

[0028] The first duration is greater than or equal to 0.1 seconds and less than or equal to 0.5 seconds; and / or,

[0029] The second duration is greater than or equal to 0.1 seconds and less than or equal to 0.5 seconds; and / or,

[0030] The third duration is greater than or equal to 0.1 seconds and less than or equal to 1 second.

[0031] In one possible implementation of the first aspect, triggering the first channel scan includes:

[0032] First, trigger two single-channel scans, then trigger a full-channel scan.

[0033] It is evident that the first device can not only quickly obtain the correct frequency using single-channel scanning, but also avoid wasting the delay caused by multiple single-channel scanning failures, thus ensuring the connection success rate between the first device and the second device and taking into account various situations in which the first device and the second device establish a P2P connection.

[0034] In one possible implementation of the first aspect, the first device acts as a peer group client (P2P GC) and the second device acts as a peer group owner (P2P GO).

[0035] In a second aspect, a communication device is provided for use with a first device, the device comprising: a module for performing the methods described in the first aspect and any possible implementation thereof.

[0036] Thirdly, a communication system is provided, comprising a first device and a second device, wherein the first device is used to perform the methods described in the first aspect and any possible implementation thereof.

[0037] Fourthly, a communication device is provided, comprising: a transceiver, a processor, and a memory. The memory stores computer programs or instructions, and the processor controls the transceiver to transmit and receive signals. The processor also calls and executes the computer programs or instructions stored in the memory, causing the processor to implement the methods described in the first aspect and any possible implementation thereof.

[0038] Fifthly, a communication device is provided, comprising: a processor; the processor being configured to invoke a computer program or instructions in a memory, causing the communication device to execute the methods described in the first aspect and any possible implementation thereof.

[0039] Optionally, the communication device further includes a memory for storing program instructions. The processor is coupled to the memory via an interface.

[0040] In a sixth aspect, a chip device is provided, including a processor for invoking a computer program or instructions in the memory to cause the processor to perform the methods described in the first aspect and any possible implementation thereof.

[0041] Alternatively, the processor may be coupled to the memory via an interface.

[0042] In a seventh aspect, a chip is provided, comprising: an interface circuit and a logic circuit, wherein the interface circuit is used to receive signals from other chips outside the chip and transmit them to the logic circuit, or to send signals from the logic circuit to other chips outside the chip, and the logic circuit is used to implement the methods in the first aspect and any possible implementation thereof.

[0043] Eighthly, a computer-readable storage medium is provided, which stores a computer program or instructions configured to perform the methods described in the first aspect and any possible implementation thereof.

[0044] Ninthly, a computer program product is provided that, when the computer program product is run on a computer, causes the computer to perform the methods described in the first aspect and any possible implementation thereof. Attached Figure Description

[0059] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of this application. Figure 1 As shown, the communication system in this application embodiment may include: GO device 10 and GC device 20.

[0060] In this system, GO device 10 and GC device 20 constitute a P2P organization or P2P network. The communication system is the system corresponding to the P2P organization or P2P network. GO device 10 acts as the P2P GO, and GC device 20 acts as the P2P GC. There is one GO device 10 and one or more GC devices 20. There is a P2P connection or P2P link between GO device 10 and each GC device 20, enabling data transmission for P2P services. For ease of explanation, Figure 1 The diagram uses one GC device 20 for illustration.

[0061] GO device 10 or GC device 20 is a device with wireless transceiver capabilities. GO device 10 or GC device 20 can be a wireless terminal or a wired terminal. A wireless terminal can be a device providing voice and / or other service data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The wireless terminal can communicate with one or more core networks via a radio access network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device, which exchanges voice and / or data with the radio access network. Examples include personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), drones, wearable devices, and terminals in vehicle-to-everything (V2X) networks. Wireless terminals can also be referred to as systems, subscriber units, subscriber stations, mobile stations (MS), mobile stations, remote stations, remote terminals, access terminals, user terminals, user agents, user devices or user equipment (UE), terminal units, terminal stations, remote stations, mobile devices, terminals, wireless communication equipment, terminal agents, or terminal devices, etc., without limitation here.

[0062] Access terminals can be cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, in-vehicle devices, wearable devices, terminal devices in 5G networks, 6G networks or future networks, or terminal devices in future evolved public land mobile networks (PLMNs), etc.

[0063] In addition, the GO device 10 or GC device 20 may use mobile operating systems such as Android, Linux, Windows, and iOS, and this application embodiment does not limit this.

[0064] In some embodiments, GO device 10 is a mobile phone and GC device 20 is a computer. Alternatively, GO device 10 is a mobile phone and GC device 20 is a vehicle.

[0065] Please see Figure 2 , Figure 2 This is a flowchart illustrating a P2P connection establishment method provided in an embodiment of this application. Figure 2 As shown, the P2P connection establishment method may include the following steps:

[0066] In step 11, during the process of GO device 10 and GC device 20, each device negotiates its chip capabilities to determine which device will act as the P2P GO and the remaining devices will act as the P2P GC. Thus, GO device 10 can create a P2P GO role, allowing it to periodically or non-periodically broadcast its information to GC device 20, enabling GC device 20 to discover GO device 10.

[0067] Step 12: After negotiation, GO device 10 sends information about GO device 10 to GC device 20, such as basic service set identifier (BSSID), service set identifier (SSID), frequency (Freq), password, etc., to achieve information transmission.

[0068] Step 13: After receiving the information from GO device 10, the chip component in GC device 20 triggers a channel scan to obtain the frequency of GO device 10 and scan to discover GO device 10.

[0069] Step 14: After the GO device 10 is detected by the scan, the GC device 20 and the GO device 10 can trigger the subsequent connection process to establish a P2P connection based on the frequency of the GO device 10, such as authentication (auth), association (assoc), and four-way handshake.

[0070] Based on the above description, in step 13, in some embodiments, the GC device 20 can receive the correct frequency from the information of the GO device 10. Therefore, the GC device 20 initiates a channel scan at the correct frequency. In this way, the GC device 20 will scan and discover the GO device 10.

[0071] In other embodiments, GC device 20 can receive the correct frequency from the information of GO device 10. However, before triggering a channel scan, GC device 20 may determine that the frequency is unreasonable due to factors such as scanning strategy, and will modify the frequency and initiate a channel scan with the modified frequency. In this way, GC device 20 will not be able to scan GO device 10.

[0072] In some embodiments, compared to GO device 10, the operating system of GC device 20 updates more slowly, resulting in fewer interfaces for its operating system and causing problems with information reception. Therefore, GO device 10 and GC device 20 negotiate a frequency. However, if this frequency is insufficient for its own code logic, GO device 10 will modify the frequency and send the modified frequency to GC device 20. Because GC device 20 has fewer interfaces, it cannot detect the modified frequency through the extra interfaces; that is, GC device 20 cannot receive the correct frequency from the information from GO device 10. Thus, GC device 20 will never be able to scan for GO device 10.

[0073] Based on the above description, the chip components in GC device 20 can adjust the scanning strategy for channel scanning.

[0074] Please see Figure 3 , Figure 3 This is a schematic diagram of a channel scanning strategy provided in an embodiment of this application. Figure 3 As shown, after receiving the command from GO device 10, the chip component first triggers four single-channel scans, followed by a full-channel scan, with intervals of 0.1s, 0.5s, 1s, 5s, 10s, and 10s, respectively. Figure 3 The runtime of single-channel scanning and full-channel scanning is not illustrated in the text.

[0075] However, without considering the time consumption of single-channel scanning and full-channel scanning themselves, only calculating the interval duration, it would take at least 6.6 seconds (s) before a full-channel scan could be triggered. Therefore, for P2P services with high connection duration requirements, such as direct screen mirroring between mobile phones and tablets, image sharing between mobile phones, and direct screen mirroring between mobile phones and large-screen devices, GO device 10 and / or GC device 20 would be set to a shorter connection duration, such as a 5-second timer. In this case, the above scanning strategy would time out, failing to meet the high connection duration requirements of P2P services.

[0076] In view of the above problems, by way of example, this application provides a communication method that uses P2P services with high connection duration requirements to adjust the number of scans and / or the scan interval in the channel scanning strategy, so that the channel scanning strategy meets the service requirements of P2P services with high connection duration.

[0077] The embodiments of this application will be described below with the following examples. Figure 1 Taking the GO device 10 and GC device 20 with the structure shown as examples, the communication method provided in this application embodiment will be described in detail with reference to the accompanying drawings and application scenarios.

[0078] Please see Figure 4 , Figure 4 This is an interactive flowchart illustrating a communication method provided in an embodiment of this application. The method is applied to a first device and a second device, wherein the first device may be... Figure 1 The GC device 20 or the apparatus in the GC device 20, the second device may be Figure 1 The GO device 10 or the apparatus within the GO device 10. For simplicity, let's take the example where the method is executed by the first device and the second device, such as... Figure 4 As shown, the communication method provided in this application embodiment may include:

[0079] S101, The second device sends a first command to the first device.

[0080] Correspondingly, the first device receives the first command sent by the second device.

[0081] The first command includes the first frequency of the second device.

[0082] After negotiation between the second device and the first device, the second device can act as a P2P GO (Peer-to-Peer) and the first device can act as a P2P GGC (Peer-to-Peer) GC (Peer-to-Peer) GC. The second device can create a P2P GO role. Therefore, the second device can send a first command to the first device, triggering the first device to scan and discover the second device.

[0083] In addition to the first frequency, the first command may also include other information about the second device, such as BSSID, SSID, and password. The first command can be sent via broadcast or other signaling methods; this application embodiment does not limit the method of transmission.

[0084] S102. The first device responds to the first command, triggers the first channel scan, and monitors the second frequency of the second device. The scanning duration of the first channel scan is less than or equal to the connection duration for the first device and the second device to achieve peer-to-peer service.

[0085] After the first device receives the first command, the first device may receive the first frequency and be able to use the first frequency, or it may receive the first frequency but be unable to use the first frequency, or it may be unable to receive the first frequency.

[0086] Based on this, regardless of the above scenario, the first device can trigger a first channel scan to detect the second frequency. The scanning strategy for the first channel scan can be optimized or adjusted based on the service requirements of the P2P service, relating the number of scans and / or the scan interval. Thus, the scan duration of the first channel scan can be less than or equal to the connection duration for the first device and the second device to perform the P2P service. The second frequency can be the same as or different from the first frequency; this application embodiment does not limit this.

[0087] The first channel scan may include single-channel scanning and / or full-channel scanning. The scanning strategy for the first channel scan may be configured with at least one of the following: the number of single-channel scans, the interval between single-channel scans, the interval between single-channel scans and full-channel scans, and the interval between full-channel scans.

[0088] When the first device receives and can use the first frequency, the single-channel scanning setting in the first channel scanning strategy can quickly scan and determine that the second frequency is the first frequency.

[0089] If the first device receives the first frequency but cannot use it, the scanning strategy of the first channel scan can quickly scan and determine the second frequency by setting a full channel scan or a combination of single channel scan and full channel scan.

[0090] If the first device cannot receive the first frequency, the scanning strategy of the first channel scan can quickly scan and determine the second frequency by setting full channel scan, or setting single channel scan and full channel scan.

[0091] In addition to detecting the second frequency, the first device can also verify the correctness of the second frequency using various methods. In some embodiments, the first device can also determine whether a media access control (MAC) address matches. If the MAC address matches, the first device can determine that the second frequency is correct. If the MAC address does not match, the first device can determine that the second frequency is incorrect. Therefore, the first device can continue to trigger the first channel scan, or the first device can block the first command, and after a certain period of time, if the second device does not receive the information sent by the second device, then the second device can continue to send the first command to the first device.

[0092] This allows the system to meet the high connection duration requirements of P2P services, making the implementation of P2P services timely and immediate.

[0093] In this application, the specific implementation of the scanning strategy for the first channel scanning is not limited.

[0094] In some embodiments, the scanning strategy of the first channel scan satisfies at least one of the following:

[0095] The number of scans for a single-channel scan is less than or equal to the first value;

[0096] The interval between single-channel scans is less than or equal to the first duration;

[0097] The interval between single-channel scanning and full-channel scanning is less than or equal to the second duration;

[0098] The interval between full-channel scans is less than or equal to the third duration.

[0099] The first value is used to limit the number of scans in a single-channel scan. The specific value of the first value is not limited in this embodiment. In some embodiments, the first value is set based on the connection success rate between the first device and other devices. The first value can be set to less than or equal to 4. For example, the first value can be 4.

[0100] Furthermore, if the scanning strategy of the first channel scan satisfies at least one of the other three conditions, the number of scans for a single channel scan can also be greater than the first value.

[0101] The first duration is used to define the interval between single-channel scans. This application embodiment does not limit the specific value of the first duration. In some embodiments, the first duration is set according to the capability of the Wi-Fi module in the first device. The first duration can be set to be greater than or equal to 0.1 seconds and less than or equal to 0.5 seconds. For example, the first duration can be 0.1 seconds.

[0102] Furthermore, if the scanning strategy of the first channel scan satisfies at least one of the other three conditions, the interval between single-channel scans is longer than the first duration, such as 0.5s.

[0103] The second duration is used to define the interval between single-channel scanning and full-channel scanning. This application embodiment does not limit the specific value of the second duration. In some embodiments, the second duration is set according to the capability of the Wi-Fi module in the first device. The second duration can be set to be greater than or equal to 0.1 seconds and less than or equal to 0.5 seconds. For example, the second duration can be 0.1 seconds.

[0104] Furthermore, if the scanning strategy of the first channel scan satisfies at least one of the other three conditions, the interval between single-channel scanning and full-channel scanning can also be greater than the second interval.

[0105] The third duration is used to define the interval between full-channel scans, and the specific value of the third duration is not limited in this embodiment. In some embodiments, the third duration is set according to the capability of the Wi-Fi module in the first device. The third duration can be set to be greater than or equal to 0.1 seconds and less than or equal to 1 second. Alternatively, the third duration can be set to be less than or equal to 0.5 seconds. For example, the third duration can be 0.25 seconds or 0.5 seconds.

[0106] The Wi-Fi module is a software module and can be located within the chip assembly of the first device. In some embodiments, the Wi-Fi module can be located in the hardware abstraction layer (HAL) of the operating system of the first device. Alternatively, the Wi-Fi module can be understood as the Wi-Fi module included in the P2P GC in Wi-Fi P2P technology.

[0107] Furthermore, if the scanning strategy of the first channel scan satisfies at least one of the other three conditions, the interval between full channel scans can also be greater than the third interval.

[0108] Furthermore, when the number of scans in a full-channel scan is greater than or equal to the second value, the interval between full-channel scans can remain unchanged, still set to be less than or equal to the third duration, or it can be changed, such as setting the interval between full-channel scans to be less than or equal to the fourth duration. In some embodiments, the fourth duration is longer than the third duration. For example, if the third duration is set to 0.25s, then the fourth duration can be set to 0.5s. Additionally, the embodiments of this application do not limit the magnitude of the second value. Furthermore, depending on the different connection duration requirements of the P2P service or device, the scanning strategy for the first channel scan of each P2P GC can be different, such as the first value, the first duration, the second duration, the third duration, or at least one of the second value and the fourth duration being different.

[0109] In addition, it should be understood that the first value, first duration, second duration, third duration, or second value and fourth duration mentioned above can be adopted as empirical values ​​to meet the software and / or hardware requirements of P2P GC, based on satisfying their respective setting rules.

[0110] S103. The first device establishes a peer-to-peer connection between itself and the second device based on the second frequency. The peer-to-peer connection is used by the first device and the second device to implement peer-to-peer services.

[0111] The first device can establish a P2P connection between itself and the second device based on the second frequency obtained by scanning, enabling P2P services to be implemented between the first device and the second device.

[0112] The process of establishing a P2P connection may include, but is not limited to, auth, assoc, 4-way handshake, etc.

[0113] The communication method provided in this application embodiment involves a second device sending a first command to a first device. This first command triggers the first device to scan and discover the second device. After receiving the first command, the first device may be unable to receive or use the first frequency. Therefore, the first device can trigger a first channel scan. Because the number of scans and / or the scan interval in the first channel scan strategy are optimized or adjusted, the scan duration of the first channel scan is less than or equal to the connection duration for the first device and the second device to achieve peer-to-peer service. In other words, the scan duration of the first channel scan is adaptable to the actual requirements of the connection duration for P2P services, especially those with high connection duration requirements. Therefore, the first device can quickly detect the correct frequency, i.e., the second frequency, while meeting the high connection duration requirements of P2P services. Thus, the first device can establish a P2P connection between the first device and the second device based on the second frequency, enabling the first device and the second device to quickly achieve real-time P2P service.

[0114] It should be understood that the embodiments of this application can be applied to various scanning scenarios of P2P GC connections, including scanning scenarios where P2P GC connections are successful or scanning scenarios where P2P GC connections fail.

[0115] In this context, a successful P2P GC connection scan scenario refers to a scenario where the P2P GC receives and can use the first frequency. A failed P2P GC connection scan scenario refers to a scenario where the P2P GC receives the first frequency but cannot use it, or where the P2P GC cannot receive the first frequency at all.

[0116] In addition, embodiments of this application may use methods such as capturing Wi-Fi air interface data or reading logs to determine whether an electronic device has triggered a first channel scan.

[0117] Based on the above description, the first device can determine the triggering method for the first channel scan according to the scanning scenario of the P2P GC connection.

[0118] In some embodiments, when a first frequency is obtained according to a first command, the first device may use the first frequency to trigger a single-channel scan, and then trigger a full-channel scan. Alternatively, the first device may use the first frequency to trigger a single-channel scan. Alternatively, the first device may directly trigger a full-channel scan.

[0119] If the first frequency is not obtained according to the first command, the first device can use the third frequency to trigger a single-channel scan, and then trigger a full-channel scan. Alternatively, the first device can use the third frequency to trigger a single-channel scan. Or, the first device can directly trigger a full-channel scan. The first device and the second device can pre-negotiate a frequency or a frequency range. The third frequency is the previously negotiated frequency. Alternatively, the third frequency is a default frequency, such as the frequency used to establish a P2P connection between the first and second devices in actual circumstances.

[0120] This allows the first device to quickly determine the correct frequency using single-channel scanning, while avoiding delays caused by single-channel scanning failures and the switching between single-channel and full-channel scanning.

[0121] In summary, the first device can adaptively adjust the number of scans and / or the scan interval.

[0122] Please see Figure 5 , Figure 5 This is a schematic diagram of a scanning strategy for a first channel scanning provided in an embodiment of this application. Figure 5As shown, as one possible implementation, the scanning strategy for the first channel scan specifically includes: the first device can first trigger two single-channel scans, and then trigger a full-channel scan. Specifically, the number of single-channel scans is set to 2, the interval between single-channel scans is set to 0.1s, the interval between full-channel scans is set to 0.25s for the first two full-channel scans (including the second full-channel scan), and the interval between full-channel scans starting from the third full-channel scan is set to 0.5s.

[0123] As another possible implementation, the scanning strategy for the first channel scan specifically includes: the first device can first trigger one or three single-channel scans, and then trigger a full-channel scan.

[0124] The interval between single-channel scans is set to 0.1s or 0.5s.

[0125] In addition, the interval between single-channel scanning and full-channel scanning is set to 0.1s.

[0126] In addition, the first device triggers a full-channel scan process. The interval between full-channel scans is set to 0.25s for the first two full-channel scans, including the second full-channel scan, and 0.5s for the third full-channel scan.

[0127] It is evident that the first device can quickly enter the next single-channel scan and also quickly enter the full-channel scan by reducing at least one of the following: the number of single-channel scans, the interval between single-channel scans, or the interval between single-channel scans and full-channel scans. This reduces the time required for full-channel scans and significantly improves the connection success rate.

[0128] In addition, the first device can quickly enter full-channel scanning by reducing the interval between full-channel scans.

[0129] As another possible implementation, the scanning strategy for the first channel scan specifically includes: the first device can trigger a full channel scan.

[0130] Specifically, the number of scans for a single channel scan is set to 0, the interval between single channel scans is set to 0.1s, the interval between a single channel scan and a full channel scan is set to 0.1s, the third interval is set to 0.25s, the number of scans for a full channel scan is 3, and the interval between full channel scans is set to a fourth interval of 0.5s.

[0131] Alternatively, the number of scans for a single channel scan is set to 0, the interval between single channel scans is set to 0.1s, the interval between a single channel scan and a full channel scan is set to 0.1s, the third interval is set to 0.25s, the number of scans for a full channel scan is 3, and the interval between full channel scans is set to a fourth interval of 0.5s.

[0132] It is evident that by canceling single-channel scanning and reducing the interval between full-channel scans, the first device can quickly enter the first full-channel scan and quickly enter the next full-channel scan, thus shortening the full-channel scan time and significantly optimizing the connection success rate.
