[0002] As is known to all, in a home wireless network, one or more repeater devices are usually connected to a gateway device such as a residential gateway (RGW) to ensure network coverage.

[0003] Currently, home wireless networks can operate in two WiFi bands: low frequency bands such as 2.4GHz and high frequency bands such as 5GHz. The 5GHz band has better throughput, but this band may conflict with the operating band of some radar signals. Therefore, when using the 5GHz band, it is necessary to switch channels based on the detection of radar signals to avoid radar signals. However, during channel switching, the communication between the RGW and the repeater device will be interrupted, so the communication between the RGW and the repeater device needs to be restored.

[0026] (b) a combination of hardware circuitry and software, such as (where applicable): (i) a combination of analog and / or digital hardware circuitry and software / firmware, and (ii) any portion of a hardware processor and software (including a digital signal processor, software and memory that work together to enable an apparatus such as an OLT or other computing device to perform various functions); and

[0027] (c) A hardware circuit and / or processor, such as a microprocessor or portion of a microprocessor, that requires software (eg, firmware) for operation but can operate without software when no software is needed for operation.

As another example, the term "circuitry" as used herein also covers an implementation of a hardware circuit or processor (or processors), or a portion of a hardware circuit or processor, or accompanying software or firmware. For example, the term "circuitry" also covers a baseband integrated circuit or a processor integrated circuit or a similar integrated circuit in an OLT or other computing device, if applicable to a particular claim element.

The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment". The relevant definitions of other terms will be given in the following description.

[0030] Figure 1 Schematic diagram of a home wireless network 100 in which embodiments of the present disclosure may be implemented is shown. Figure 1 As shown, the home wireless network 100 includes a gateway device 110 and repeater devices 121 and 122. It should be understood that the home wireless network 100 may include more or fewer repeater devices, and is not limited to the case shown in the figure. The gateway device 110 can establish a wireless connection with the repeater devices 121 and 122, such as a WiFi connection, such as on a channel in a frequency band such as 5GHz, 2.4GHz, etc. Users in the wireless network 100 can access the Internet via any device of the gateway device 110, repeater devices 121 and 122. By setting up the repeater device, the coverage distance of the wireless network can be extended and ensured.

[0031] As mentioned above, 5GHz WiFi is currently being paid attention to and used due to its superior throughput. However, this frequency band conflicts with the operating frequency band of radar signals, so it is necessary to use dynamic frequency selection (DFS) technology to avoid radar signals. Generally, the gateway device 110 and the repeater devices 121 and 122 both detect radar signals, and immediately switch the operating channel when a radar signal is detected to switch to a channel in a non-radar operating frequency band.

[0032] In some cases, for example, when the radar signal is relatively weak, the gateway device 110 and the repeater devices 121 and 122 may not all detect the radar signal, but only some of the devices detect the radar signal. In this way, only some of the devices perform the switching of the working channel, resulting in the interruption of the communication between the gateway device and the repeater device. Moreover, after the working channel is switched, it is impossible to re-enter the channel where the radar signal is located for at least a period of time, for example, 30 minutes.

[0033] Therefore, in the traditional solution, when the repeater device detects that the communication with the gateway device is interrupted, it usually scans the 5GHz channel and finds the channel where the gateway device is located, and then restores the communication with the gateway device. However, this takes a long time, resulting in a decrease in system performance.

[0034] In another traditional solution, when the repeater device detects that the communication with the gateway device is interrupted, it abandons the 5GHz channel and establishes a connection with the gateway device via the 2.4GHz channel, and then restores the communication with the gateway device. Obviously, this solution can restore communication faster than the previous solution, but it can no longer use the high throughput performance of the 5GHz channel, so the communication performance is greatly affected.

[0035] The purpose of the present disclosure is to quickly restore the communication between the gateway device and the repeater device in the case where only some devices perform working channel switching. The basic concept of the present disclosure is that when any one of the gateway device 110 and the repeater devices 121, 122 detects an event that triggers the switching of the working channel, it performs the switching of the working channel and notifies the other party of the switch so that the other party also performs the switch, thereby quickly restoring the communication between them. According to an embodiment of the present disclosure, the event that triggers the switching of the working channel can be the detection of the radar signal as mentioned above, or it can be a user instruction to actively switch the channel, or other similar events. It should be understood that the embodiments of the present disclosure are applicable to the recovery of communication interruption after some devices perform working channel switching, and are not limited to solving the traditional technical problems described above. The following is combined with Figure 2 and Figure 3 A more detailed description is given.

[0036] Figure 2 A gateway device (eg, Figure 1 Gateway device 110) and repeater device (eg Figure 1 Schematic diagram 200 of the interaction between the repeater devices 121, 122 of the gateway device 110. An example of this interaction is a case where an event that triggers switching of the working channel is detected on the gateway device 110 side.

[0037] like Figure 2 As shown, the gateway device 110 detects 201 an event that triggers switching of the working channel. For example, in some embodiments, the gateway device 110 may detect a radar signal in the current working channel (also referred to as the first channel). In other embodiments, the gateway device 110 may receive a user instruction for switching the working channel, such as a user reconfiguring the working channel. It should be understood that the present disclosure is not limited to the above examples, and may also include other events that trigger switching of the working channel.

[0038] In response to detecting 201 the event, the gateway device 110 sends 202, 203 instructions about the switching of the working channel to each repeater device 121, 122. In some embodiments, the gateway device 110 can send the instruction via a known message such as a channel switch notification (CSA) message. Thus, existing resources can be fully utilized and development costs can be saved. In other embodiments, the gateway device 110 can send the instruction via a newly defined message. It should be understood that the present disclosure is not limited to this.

[0039] In some embodiments of the present disclosure, for example, when the channel switched to is a predetermined channel, the indication may only include an indicator indicating the working channel switching. In other embodiments of the present disclosure, the indication may include information about the channel to be switched to.

[0040] In response to detecting 201 the event, the gateway device 110 also switches 204 from the first channel to a second channel different from the first channel. It should be understood that operation 204 can be performed at the same time, before or after operations 202 and 203, and the present application is not limited to this. According to an embodiment of the present disclosure, the first channel and the second channel can operate in a high WiFi frequency band, such as 5 GHz. In an alternative embodiment, the first channel and the second channel can also operate in a low WiFi frequency band, such as 2.4 GHz. In other alternative embodiments, the first channel and the second channel can operate in different frequency bands.

[0041] According to an embodiment of the present disclosure, the second channel may be a predetermined channel. This can reduce the amount of information transmitted, save network resources, and improve communication efficiency. In some embodiments, the predetermined channel may operate in a frequency band other than the operating frequency band of the radar signal, that is, a channel of a non-radar operating frequency band. This application does not limit this. In an alternative embodiment, the second channel may not be predetermined, but configured in real time. This can improve the flexible use of channels and improve overall network performance.

[0042] Continue to refer Figure 2 , the repeater device 121 switches 205 from the first channel to the second channel in response to receiving the instruction about switching sent 202 by the gateway device 110. Similarly, the repeater device 122 switches 206 from the first channel to the second channel in response to receiving the instruction about switching sent 203 by the gateway device 110. It should be understood that operations 204, 205, and 206 can be performed simultaneously or in any time sequence, and the present application is not limited thereto.

[0043] Compared with the traditional solution, according to the embodiment of the present disclosure, when the gateway device 110 detects an event that triggers the switching of the working channel and performs channel switching, thereby causing the communication with the repeater devices 121 and 122 to be interrupted, the repeater devices 121 and 122 do not need to scan to find the channel where the gateway device 110 is located, but can directly determine the channel where the gateway device 110 is located from the received indication of the switching. Therefore, the communication with the gateway device 110 can be quickly restored, thereby improving the overall network performance.

[0044] Figure 3 A gateway device (eg, Figure 1 Gateway device 110) and repeater device (eg Figure 1 Schematic diagram 300 of the interaction between the repeater devices 121, 122 of FIG. 1. An example of the interaction is a case where an event triggering switching of the working channel is detected on the repeater device side (eg, the repeater device 122).

[0045] like Figure 3 As shown, the repeater device 122 detects 301 an event that triggers switching of the working channel. For example, in some embodiments, the repeater device 122 may detect a radar signal in the current working channel (also referred to as the first channel). In other embodiments, the repeater device 122 may receive a user instruction for switching the working channel, such as a user reconfiguring the working channel. It should be understood that the present disclosure is not limited to the above examples, and may also include other events that trigger switching of the working channel.

[0046] In response to detecting 301 the event, the repeater device 122 may switch 302 from the first channel to the second channel. According to an embodiment of the present disclosure, the first channel and the second channel may operate in a high WiFi frequency band, such as 5 GHz, etc. In an alternative embodiment, the first channel and the second channel may also operate in a low WiFi frequency band, such as 2.4 GHz, etc. In other alternative embodiments, the first channel and the second channel may operate in different frequency bands.

[0047] According to an embodiment of the present disclosure, the second channel may be a predetermined channel. In some embodiments, the predetermined channel may operate in a frequency band other than the operating frequency band of the radar signal, that is, a channel of a non-radar operating frequency band. The present application does not limit this. In an alternative embodiment, the second channel may not be predetermined, but configured in real time.

[0048] Continue to refer Figure 3 , the repeater device 122 establishes 303 a connection with the gateway device 110 via a third channel, which is different from the first channel and the second channel. According to an embodiment of the present disclosure, the third channel may operate in a low WiFi frequency band, such as 2.4 GHz. For example, in the case where the repeater device 122 detects 301 a radar signal, the repeater device 122 may establish a connection with the gateway device 110 via a channel in the 2.4 GHz frequency band as a station.

[0049] In an alternative embodiment, the third channel may also operate in a high WiFi frequency band, such as 5 GHz, etc. For example, when the repeater device 122 receives a user instruction to switch the working channel, the repeater device 122 may establish a connection with the gateway device 110 via other channels in the 5 GHz frequency band.

[0050] Via the established connection, the repeater device 122 reports or sends 304 information about the working channel switch to the gateway device 110. In some embodiments of the present disclosure, for example, when the switched channel is a predetermined channel, the information may only include an indicator indicating the working channel switch. In other embodiments of the present disclosure, the information may include information about the channel to be switched to.

[0051] In response to receiving the information about the working channel switching, the gateway device 110 may send 305 an indication of the switching to other repeater devices (e.g., the repeater device 121). In response to receiving the information about the working channel switching, the gateway device 110 may also switch 306 from the first channel to the second channel. It should be understood that operation 306 may be performed at the same time, before, or after operation 305, and the present application does not limit this.

[0052] In response to receiving the instruction sent 305 by the gateway device 110, the repeater device 122 switches 307 from the first channel to the second channel. It should be understood that operations 306 and 307 can be performed simultaneously or in any time sequence, and the present application does not limit this. As a result, the communication between the gateway device 110 and the repeater devices 121 and 122 is quickly restored.

[0053] Compared with traditional solutions, according to an embodiment of the present disclosure, when a repeater device (such as repeater device 122) detects an event that triggers switching of a working channel and performs channel switching, thereby causing communication with a gateway device to be interrupted, the repeater device 122 can report the switch by temporarily establishing any connection with the gateway device, so that the gateway device 110 and other repeater devices 121 can perform the same switch, thereby quickly restoring communication without sacrificing high throughput performance.

[0054] The basic concept of the embodiments of the present disclosure has been described in detail. Based on this concept, the embodiments of the present disclosure provide corresponding communication methods and devices for home wireless networks. Figures 4 to 7 This is described in detail.

[0055] Figure 4 A flow chart of a communication method 400 for a home wireless network according to some embodiments of the present disclosure is shown. The method 400 may be implemented in a gateway device (e.g. Figure 1 The method is implemented at a gateway device 110).

[0056] like Figure 4 As shown, at block 410, the gateway device 110 may detect an event that triggers switching of the working channel. Figure 2 In response to the gateway device 110 detecting the event, the process may proceed to block 420. In block 420, the gateway device 110 switches from the first channel to the second channel. Figure 2 At block 430, the gateway device 110 may send a signal to a repeater device (eg, Figure 1 The repeater devices 121, 122) send a switching instruction so that each repeater device switches from the first channel to the second channel in response to the instruction. The processing process can be referred to in conjunction with Figure 2 The description of operations 202 and 203 is omitted here.

[0057] Figure 5 A flow chart of a communication method 500 for a home wireless network according to some embodiments of the present disclosure is shown. The method 500 may be implemented in a repeater device (e.g. Figure 1The method 500 and the method 400 are corresponding operation processes.

[0058] like Figure 5 As shown, at block 510, the repeater devices 121, 122 may receive a signal from a gateway device (eg, Figure 1 In response to receiving the instruction, the repeater devices 121 and 122 may switch from the first channel to the second channel. Figure 2 The description of operations 205 and 206 is omitted here.

[0059] pass Figure 4 and Figure 5 In methods 400 and 500, the gateway device can quickly restore the communication between the gateway device and the repeater device by notifying all repeater devices of the switching of the working channel, without the repeater device performing channel scanning. Therefore, the overall network performance is improved, ensuring a good user experience.

[0060] Refer to above Figure 4 and Figure 5 The following describes the processing process when an event that triggers the switching of the working channel is detected at the gateway device. Figure 6 and Figure 7 The processing procedure is described in the case where an event that triggers a switching of an operating channel is detected at a repeater device.

[0061] Figure 6 A flow chart of a communication method 600 for a home wireless network according to some other embodiments of the present disclosure is shown. The method 600 may be performed in a repeater device (e.g. Figure 1 The following description is made by taking the repeater device 122 as an example.

[0062] like Figure 6 As shown, at block 610, the repeater device 122 may detect an event that triggers switching of the operating channel. Figure 3 In response to the repeater device 122 detecting the event, block 620 may be entered. In block 620, the repeater device 122 switches from the first channel to the second channel. The processing process may be referred to above in conjunction with Figure 3 At block 630, the repeater device 122 may send a signal to a gateway device (eg, Figure 1The gateway device 110 sends information about the switch so that the gateway device 110 and other repeater devices switch from the first channel to the second channel. Figure 3 The description of operations 303 and 304 is omitted here.

[0063] Figure 7 A flow chart of a communication method 700 for a home wireless network according to some other embodiments of the present disclosure is shown. The method 700 may be implemented in a gateway device (e.g. Figure 1 The method 700 and the method 600 are corresponding operation processes.

[0064] like Figure 7 As shown, at block 710, the gateway device 110 may receive a request from any repeater device (eg, Figure 1 In block 720, in response to receiving the information, the gateway device 110 may switch from the first channel to the second channel. The processing process may be referred to in conjunction with the above Figure 3 The description of operation 306 is omitted here.

[0065] At block 730, the gateway device 110 also sends a message to other repeater devices (eg, Figure 1 The repeater device 121) sends a switching instruction so that each device in the other devices switches from the first channel to the second channel. The processing process can be referred to in conjunction with Figure 3 The description of operations 305 and 307 is omitted here.

[0066] pass Figure 6 and Figure 7 In the methods 600 and 700, the repeater device can report the switching of the working channel to the gateway device by means of the temporary channel connection, so that the gateway device makes the same switch and notifies other repeater devices to make the same switch, thereby quickly restoring the communication between the gateway device and the repeater device while ensuring high throughput performance. Therefore, the overall network performance is improved, ensuring a good user experience.
