Description

Technical Field

[0001] The embodiments of the present application relate to the field of smart terminal technology, and in particular to a method and device for starting a wireless network in a router, and a router. Background Art

[0002] In the existing related technology, for routers that support 160M bandwidth, since the available channels of the wireless fidelity (Wi-Fi) network overlap with the channels used by radar signals, the routers that support 160M bandwidth need to perform dynamic frequency selection (DFS) channel scanning when they are turned on to confirm whether there are radar signals on the channel, thereby avoiding the overlap of the channels selected by the Wi-Fi network and the channels used by radar signals.

[0003] The router can only complete startup after the DFS scan determines the optimal channel to use. The entire DFS scan takes 60 seconds. Combined with other time-consuming processes during the router startup process, the router startup process takes a long time and the user experience is poor. Summary of the Invention

[0004] Embodiments of the present application provide a method and apparatus for starting a wireless network in a router, and a router. Embodiments of the present application also provide a computer-readable storage medium to shorten the time consumption of the router startup process and improve the user experience.

[0005] In a first aspect, an embodiment of the present application provides a method for starting a wireless network in a router, comprising: after the router is powered on, loading a Wi-Fi driver; after the Wi-Fi driver is loaded, selecting a channel of a first bandwidth from a non-dynamic frequency selection channel of a Wi-Fi channel; and configuring the channel of the first bandwidth to the firmware of the router to complete the startup of the Wi-Fi network.

[0006] In the above-mentioned method for starting a wireless network in a router, after the router is powered on, the Wi-Fi driver is loaded. After the Wi-Fi driver is loaded, the router does not perform DFS channel scanning, but directly selects a channel with a first bandwidth from non-DFS channels of the Wi-Fi channel, and configures the channel with the first bandwidth to the router firmware to complete the startup of the Wi-Fi network. In other words, the router does not start the Wi-Fi network on a DFS channel, but instead starts the Wi-Fi network on a non-DFS channel. Therefore, the router does not need to perform DFS channel scanning first, thereby shortening the time taken for the router startup process, speeding up the Wi-Fi startup process, increasing the speed at which access devices scan for Wi-Fi networks, and improving the user experience.

[0007] In one possible implementation, after configuring the channel of the first bandwidth to the firmware of the router to complete the startup of the Wi-Fi network, the method further includes: determining whether an access device has accessed the Wi-Fi network; if no access device has accessed the Wi-Fi network, performing a dynamic frequency selection channel scan on the Wi-Fi channel; or, if an access device has accessed the Wi-Fi network but the access device is not performing any service, performing a dynamic frequency selection channel scan on the Wi-Fi channel.

[0008] In one possible implementation, after performing dynamic frequency selection channel scanning on the Wi-Fi channel, the method further includes: if no radar signal exists on the Wi-Fi channel, then when no access device is connected to the Wi-Fi network, selecting a channel with a second bandwidth from the Wi-Fi channel; and configuring the second bandwidth channel to the router firmware. The second bandwidth is greater than the first bandwidth.

[0009] In one possible implementation, after performing dynamic frequency selection channel scanning on the Wi-Fi channel, the method further includes: if no radar signal exists on the Wi-Fi channel, then when an access device accesses the Wi-Fi network, and the access device accessing the Wi-Fi network includes an access device that does not support the second bandwidth, waiting for the access device accessing the Wi-Fi network to be idle, selecting a channel with the second bandwidth from the Wi-Fi channels, and configuring the second bandwidth channel to the router firmware. The second bandwidth is greater than the first bandwidth.

[0010] In one possible implementation, after performing dynamic frequency selection channel scanning on the Wi-Fi channel, the method further includes: if no radar signal exists on the Wi-Fi channel, notifying the access device of a bandwidth switching event when an access device accesses the Wi-Fi network and all access devices accessing the Wi-Fi network support the second bandwidth; receiving a message from the access device confirming bandwidth switching; selecting a channel with the second bandwidth from the Wi-Fi channel; and configuring the second bandwidth channel in the router firmware. The second bandwidth is greater than the first bandwidth.

[0011] In one possible implementation, after performing dynamic frequency selection channel scanning on the Wi-Fi channel, the method further includes: if no radar signal exists on the Wi-Fi channel, then when an access device accesses the Wi-Fi network and all access devices accessing the Wi-Fi network support a second bandwidth, determining that the access device is in a non-low latency scenario, selecting a channel with the second bandwidth from the Wi-Fi channels; and configuring the second bandwidth channel in the router firmware. The second bandwidth is greater than the first bandwidth.

[0012] In a second aspect, embodiments of the present application provide a device for activating a wireless network in a router. This device is included in the router and has the function of implementing the router behavior described in the first aspect and possible implementations of the first aspect.

[0029] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0030] In existing related technologies, the 802.11 protocol requires that routers that support 160M bandwidth must perform a DFS channel scan after powering on to confirm whether there are radar signals on the Wi-Fi channel to avoid overlapping between the channel selected by the router and the channel occupied by the radar signal.

[0031] Figure 1 The schematic diagram of the router startup process provided in the existing related technology is as follows: Figure 1As shown in the figure, after the router is powered on, it first performs system initialization, followed by loading the drivers for each module. After the Wi-Fi driver is loaded, a DFS channel scan begins, which ends after 60 seconds. If there are no radar signals on the Wi-Fi channel, the optimal full-band channel (160 Mbps bandwidth) is selected and configured for the firmware. If there are radar signals on the Wi-Fi channel, the optimal channel (80 Mbps bandwidth) is selected from non-DFS Wi-Fi channels and configured for the firmware. After the Wi-Fi channel is configured, Wi-Fi startup is complete.

[0032] As can be seen from the above description, after the router is powered on, a DFS scan must be performed to determine the last used channel and bandwidth. The DFS scan takes at least 60 seconds. Combined with other time consumed during the router's operating system startup process, this results in slow router startup and slow Wi-Fi startup, resulting in a poor user experience.

[0033] In view of the above problems, an embodiment of the present application provides a method for starting a wireless network in a router, which can shorten the time consumption of the router startup process, speed up the Wi-Fi startup process, and improve the user experience.

[0034] The method for starting a wireless network in a router provided in an embodiment of the present application can be applied to the router. For example, Figure 2 A schematic diagram of the structure of a router provided in one embodiment of the present application is shown in FIG. Figure 2 As shown, the router 200 may include one or more processors 210, a communication interface 220 and a memory 230; and one or more computer programs, wherein the one or more computer programs are stored in the memory 230, and the one or more computer programs include instructions. When the instructions are executed by the router 200, the router 200 executes the method for starting a wireless network in the router provided in the embodiment of the present application.

[0035] The processor 210, the communication interface 220 and the memory 230 can communicate with each other through an internal connection path to transmit control and / or data signals. The memory 230 is used to store computer programs, and the processor 210 is used to call and run the computer program from the memory 230.

[0036] The processor 210 and the memory 230 may be combined into a processing device, or more commonly, they are independent components, with the processor 210 being configured to execute program codes stored in the memory 230. In a specific implementation, the memory 230 may also be integrated into the processor 210 or independent of the processor 210.

[0037] Optionally, the router 200 may further include a power supply 250 for providing power to various devices or circuits in the router 200 .

[0038] It should be understood that Figure 2 The processor 210 in the router 200 shown may be a system on chip (SOC), which may include a central processing unit (CPU) and may further include other types of processors, such as a graphics processing unit (GPU).

[0039] For ease of understanding, the following examples of this application will be described with Figure 2 Taking the router with the structure shown as an example, the method for starting a wireless network in the router provided in the embodiment of the present application is specifically described in combination with the accompanying drawings and application scenarios.

[0040] Figure 3 A flowchart of a method for starting a wireless network in a router provided in one embodiment of the present application is shown in FIG. Figure 3 As shown, the method for starting a wireless network in the above router may include:

[0041] In step 301 , after the router 200 is powered on, the Wi-Fi driver is loaded.

[0042] Step 302: After the Wi-Fi driver is loaded, the router 200 selects a channel with a first bandwidth from non-DFS channels of the Wi-Fi channel.

[0043] The size of the first bandwidth may be set according to system performance and / or implementation requirements during specific implementation. This embodiment does not limit the size of the first bandwidth. For example, the first bandwidth may be 80M.

[0044] Specifically, since the frequency bands available for Wi-Fi channels are regulated, DFS channels can be used to expand the available frequency bands for Wi-Fi channels to improve wireless network performance. DFS channels typically include frequency bands reserved for radar signals. Thus, the Wi-Fi channels available to router 200 include both DFS and non-DFS channels. DFS channels may be occupied by radar signals, while non-DFS channels are not.

[0045] DFS dynamically adjusts the communication channel between router 200 and access devices in a wireless LAN. It is a mechanism that dynamically monitors radar signals and avoids interference. Because DFS channels can be occupied by radar signals, router 200 must first scan for DFS channels within Wi-Fi channels to ensure they are clear of radar signals. This time-consuming DFS channel scan can lead to slow Wi-Fi startup when the router is turned on.

[0046] In this embodiment, after the Wi-Fi driver is loaded, the router 200 does not perform DFS channel scanning, but directly selects a channel with the first bandwidth from the non-DFS channels of the Wi-Fi channel. In other words, the router 200 does not start the Wi-Fi network on the DFS channel, but starts the Wi-Fi network on the non-DFS channel. Therefore, there is no need to perform DFS channel scanning, which can reduce the startup time of the router 200 and speed up the speed at which the access device scans the Wi-Fi network.

[0047] In step 303 , the router 200 configures a channel of the first bandwidth to the firmware of the router 200 to complete the startup of the Wi-Fi network.

[0048] Specifically, the router 200 configuring the channel of the first bandwidth to the firmware of the router 200 may be: the router 200 configuring the channel of the first bandwidth to the Wi-Fi chip in the router 200 .

[0049] In the above-mentioned method for starting a wireless network in a router, after the router 200 is powered on, the Wi-Fi driver is loaded. After the Wi-Fi driver is loaded, the router 200 does not perform DFS channel scanning, but directly selects a channel with a first bandwidth from non-DFS channels of the Wi-Fi channel. The first bandwidth channel is configured to the firmware of the router 200 to complete the startup of the Wi-Fi network. In other words, the router 200 does not start the Wi-Fi network on the DFS channel, but instead starts the Wi-Fi network on a non-DFS channel. Therefore, the router 200 does not need to perform DFS channel scanning first, thereby shortening the startup time of the router 200, speeding up the Wi-Fi startup process, increasing the speed at which access devices scan for Wi-Fi networks, and improving the user experience.

[0050] Figure 4 A flowchart of a method for starting a wireless network in a router provided in another embodiment of the present application is shown in FIG. Figure 4 As shown, this application Figure 3 In the illustrated embodiment, after step 303, the following steps may also be included:

[0051] In step 401, the router 200 determines whether any access device has accessed the Wi-Fi network.

[0052] The access device may be an electronic device connected to the router 200, such as a smart phone, a tablet computer, a laptop computer, a personal computer (PC), a smart speaker, a smart screen or other electronic devices.

[0053] In step 402, if no access device has accessed the Wi-Fi network, the router 200 performs a DFS channel scan on the Wi-Fi channel; or, if an access device has accessed the Wi-Fi network but the access device is not performing any service, the router 200 performs a DFS channel scan on the Wi-Fi channel.

[0054] That is, in this embodiment, the router 200 performs DFS channel scanning only after completing the startup of the Wi-Fi network, thereby speeding up the startup process of the Wi-Fi network and shortening the startup time of the router 200. In addition, before the router 200 performs DFS channel scanning, it is necessary to first determine whether there is an access device connected to the above-mentioned Wi-Fi network. If an access device is connected to the above-mentioned Wi-Fi network, the router 200 will not perform DFS channel scanning first. When no access device is connected to the above-mentioned Wi-Fi network, or when an access device is connected to the above-mentioned Wi-Fi network but the access device is not performing any service, the router 200 performs DFS channel scanning again, thereby avoiding the impact of DFS channel scanning on the service of the access device.

[0055] Figure 5 A flowchart of a method for starting a wireless network in a router provided in another embodiment of the present application is shown in FIG. Figure 5 As shown, this application Figure 4 In the illustrated embodiment, after step 402, the following steps may also be included:

[0056] Step 501: If there is no radar signal on the Wi-Fi channel, and when no access device has accessed the Wi-Fi network, the router 200 selects a channel with a second bandwidth from the Wi-Fi channel.

[0057] Among them, the second bandwidth is greater than the first bandwidth. The size of the second bandwidth can be set according to system performance and / or implementation requirements during specific implementation. This embodiment does not limit the size of the second bandwidth, but it is required that the second bandwidth is greater than the first bandwidth. For example, the second bandwidth can be 160M.

[0058] In step 502 , the router 200 configures the second bandwidth channel to the firmware of the router 200 .

[0059] Figure 6 A flowchart of a method for starting a wireless network in a router provided in another embodiment of the present application is shown in FIG. Figure 6 As shown, this application Figure 4 In the illustrated embodiment, after step 402, the following steps may also be included:

[0060] In step 601, if no radar signal exists on the Wi-Fi channel, when an access device accesses the Wi-Fi network, and the access device accessing the Wi-Fi network includes an access device that does not support the second bandwidth, the router 200 waits for the access device accessing the Wi-Fi network to be idle before selecting a channel with the second bandwidth from the Wi-Fi channels.

[0061] Among them, the second bandwidth is greater than the first bandwidth. The size of the second bandwidth can be set according to system performance and / or implementation requirements during specific implementation. This embodiment does not limit the size of the second bandwidth, but it is required that the second bandwidth is greater than the first bandwidth. For example, the second bandwidth can be 160M.

[0062] Specifically, when an access device accesses the Wi-Fi network of router 200, it sends an association message to router 200, which includes the bandwidth capabilities supported by the access device. In other words, the access device includes its ability to support 40M bandwidth, 80M bandwidth, or 160M bandwidth in the association message. After receiving the association message from the access device, router 200 can store the bandwidth capabilities supported by the access device.

[0063] In this embodiment, when there is no radar signal on the Wi-Fi channel, an access device has been connected to the Wi-Fi network, and the access device connected to the Wi-Fi network includes an access device that does not support the second bandwidth, the router 200 first maintains the channel of the first bandwidth unchanged, waits until all access devices connected to the Wi-Fi network are in an idle state, and then performs bandwidth switching and selects a channel of the second bandwidth from the Wi-Fi channels, thereby avoiding affecting the services of the access devices.

[0064] In step 602 , the router 200 configures the second bandwidth channel to the firmware of the router 200 .

[0065] Figure 7 A flowchart of a method for starting a wireless network in a router provided in another embodiment of the present application is shown in FIG. Figure 7 As shown, this application Figure 4 In the illustrated embodiment, after step 402, the following steps may also be included:

[0066] In step 701, if there is no radar signal on the Wi-Fi channel, when an access device accesses the Wi-Fi network and all the access devices accessing the Wi-Fi network support the second bandwidth, the router 200 notifies the access device of a bandwidth switching event.

[0067] Step 702: The router 200 receives a message from the access device confirming to switch the bandwidth.

[0068] In step 703 , the router 200 selects a channel with a second bandwidth from the aforementioned Wi-Fi channels.

[0069] In step 704 , the router 200 configures the second bandwidth channel to the firmware of the router 200 .

[0070] Among them, the second bandwidth is greater than the first bandwidth. The size of the second bandwidth can be set according to system performance and / or implementation requirements during specific implementation. This embodiment does not limit the size of the second bandwidth, but it is required that the second bandwidth is greater than the first bandwidth. For example, the second bandwidth can be 160M.

[0071] In this embodiment, when there is no radar signal on the above-mentioned Wi-Fi channel, and an access device is connected to the above-mentioned Wi-Fi network, and the access devices connected to the above-mentioned Wi-Fi network all support the second bandwidth, the router 200 can notify the above-mentioned access device of the bandwidth switching event through an action frame. After receiving the action frame, the access device can vote to determine whether to perform bandwidth switching. After the access device determines to perform bandwidth switching, the access device sends a message to the router 200 to determine whether to perform bandwidth switching. It is easy to imagine that the access device will only perform bandwidth switching after determining that the bandwidth switching has no impact or little impact on its own business. Therefore, in this embodiment, the bandwidth switching event is notified to the access device, and the access device determines to perform bandwidth switching, which can reduce the impact on the access device's own business.

[0072] After the router 200 receives the message confirming bandwidth switching, the router 200 selects a channel of the second bandwidth from the above-mentioned Wi-Fi channels, configures the above-mentioned channel of the second bandwidth to the firmware of the router 200, and can switch the access device accessing the above-mentioned Wi-Fi network from the channel of the first bandwidth to the channel of the second bandwidth through the channel switch announcement (CSA) process.

[0073] Figure 8 A flowchart of a method for starting a wireless network in a router provided in another embodiment of the present application is shown in FIG. Figure 8As shown, this application Figure 4 In the illustrated embodiment, after step 402, the following steps may also be included:

[0074] In step 801, if no radar signal exists on the Wi-Fi channel, when an access device accesses the Wi-Fi network and all access devices accessing the Wi-Fi network support the second bandwidth, the router 200 determines that the access device is in a non-low-latency scenario and selects a channel with the second bandwidth from the Wi-Fi channels.

[0075] Among them, the second bandwidth is greater than the first bandwidth. The size of the second bandwidth can be set according to system performance and / or implementation requirements during specific implementation. This embodiment does not limit the size of the second bandwidth, but it is required that the second bandwidth is greater than the first bandwidth. For example, the second bandwidth can be 160M.

[0076] In this embodiment, when there is no radar signal on the above-mentioned Wi-Fi channel, and an access device is connected to the above-mentioned Wi-Fi network, and all access devices connected to the above-mentioned Wi-Fi network support the second bandwidth, the router 200 can make a judgment on its own. When all access devices connected to the above-mentioned Wi-Fi network are in a non-low latency scenario, the router 200 can trigger bandwidth switching on its own and select a channel with the second bandwidth from the above-mentioned Wi-Fi channels.

[0077] In step 802 , the router 200 configures a channel of the second bandwidth to the firmware of the router 200 .

[0078] This application Figures 5 to 8 In the illustrated embodiment, the router 200 configuring the second bandwidth channel to the firmware of the router 200 may be: the router 200 configuring the second bandwidth channel to the Wi-Fi chip in the router 200 .

[0079] In addition, this application Figures 5 to 8 In the illustrated embodiment, after the router 200 performs a DFS channel scan on the Wi-Fi channel, if no radar signal exists on the Wi-Fi channel, the router 200 may first determine whether the channel quality of the second bandwidth channel is higher than the channel quality of the first bandwidth channel currently used by the router 200. If so, the router 200 continues to perform the bandwidth switching process. If the channel quality of the second bandwidth channel is lower than or equal to the channel quality of the first bandwidth channel currently used, the router 200 may determine that the second bandwidth channel has greater interference and does not perform bandwidth switching.

[0080] It should be noted that this application Figures 5 to 8In the illustrated embodiment, after step 402 , if a radar signal exists on the Wi-Fi channel, the current process ends, that is, the router 200 still maintains using the channel with the first bandwidth.

[0081] Figure 9 A flowchart of a method for starting a wireless network in a router provided in another embodiment of the present application is shown in FIG. Figure 9 As shown, the method for starting a wireless network in the above router may include:

[0082] Step 901: After the router 200 is powered on, the Wi-Fi driver is loaded.

[0083] Step 902: After the Wi-Fi driver is loaded, the router 200 selects a channel with a first bandwidth from non-DFS channels of the Wi-Fi channel.

[0084] In step 903 , the router 200 configures a channel of the first bandwidth to the firmware of the router 200 to complete the startup of the Wi-Fi network.

[0085] In step 904, the router 200 determines whether any access device has accessed the Wi-Fi network. If not, step 906 is executed; if yes, that is, an access device has accessed the Wi-Fi network, step 905 is executed.

[0086] Step 905 , determining whether the access device connected to the above-mentioned Wi-Fi network is performing a service; if so, wait until the service is completed and then execute step 906 ; if not, that is, the access device connected to the above-mentioned Wi-Fi network is not performing a service, then execute step 906 .

[0087] In step 906 , the router 200 performs a DFS channel scan on the Wi-Fi channel.

[0088] Step 907: DFS channel scanning ends.

[0089] Generally speaking, a DFS channel scan takes 60 seconds.

[0090] Step 908: Determine whether there is a radar signal on the Wi-Fi channel. If so, the process ends, i.e., the router 200 continues to use the channel with the first bandwidth. If not, i.e., there is no radar signal on the Wi-Fi channel, then step 909 is executed.

[0091] Step 909 determines whether the channel quality of the second bandwidth channel is higher than the channel quality of the first bandwidth channel currently used by router 200. If so, step 911 is executed; if not, that is, the channel quality of the second bandwidth channel is lower than or equal to the channel quality of the first bandwidth channel currently used, step 910 is executed.

[0092] In step 910, the router 200 determines that the channel interference of the second bandwidth is relatively large and does not perform bandwidth switching.

[0093] Step 911: Determine whether any access device has accessed the Wi-Fi network. If not, proceed to step 915; if yes, that is, an access device has accessed the Wi-Fi network, proceed to step 912.

[0094] Step 912: Determine whether the access devices accessing the Wi-Fi network include an access device that does not support the second bandwidth. If not, that is, all the access devices accessing the Wi-Fi network support the second bandwidth, execute step 913. If yes, that is, the access devices accessing the Wi-Fi network include an access device that does not support the second bandwidth, execute step 914.

[0095] In step 913 , the router 200 notifies the access device of the bandwidth switching event and receives a message from the access device confirming bandwidth switching; or the router 200 determines that the access device is in a non-low latency scenario. Then, step 915 is executed.

[0096] In step 914 , the router 200 waits for the access device connected to the Wi-Fi network to be in an idle state.

[0097] In step 915 , the router 200 selects a channel with a second bandwidth from the aforementioned Wi-Fi channels.

[0098] In step 916 , the router 200 configures the second bandwidth channel to the firmware of the router 200 .

[0099] and Figure 1 By comparison, it can be seen that in the method for starting a wireless network in a router provided in this embodiment, after the Wi-Fi driver is loaded, the router 200 does not perform DFS channel scanning. Instead, it selects a channel with the first bandwidth from non-DFS channels in the Wi-Fi channels and configures the channel with the first bandwidth to the firmware of the router 200 to complete the startup of the Wi-Fi network. In other words, the router 200 does not start the Wi-Fi network on the DFS channel, but starts the Wi-Fi network on the non-DFS channel. Therefore, the router 200 does not need to perform DFS channel scanning first, thereby shortening the startup time of the router 200, speeding up the Wi-Fi startup process, increasing the speed at which the access device scans the Wi-Fi network, and improving the user experience.

[0100] After the Wi-Fi network is started, the router 200 performs DFS channel scanning to expand the bandwidth of the Wi-Fi channel, thereby improving wireless access performance. When expanding the bandwidth of the Wi-Fi channel, the router 200 chooses to do so without affecting the services of the connected devices, thereby avoiding affecting the services of the connected devices.

[0101] It is understood that some or all of the steps or operations in the above embodiments are merely examples, and the present application embodiments may also perform other operations or variations of various operations. In addition, the various steps may be performed in a different order than those presented in the above embodiments, and it is possible that not all of the operations in the above embodiments need to be performed.

[0102] It is understandable that, in order to implement the above functions, the router includes hardware and / or software modules that perform the corresponding functions.
