Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a control method, apparatus, device, chip and system for a gateway device. Background Art

[0002] In a wireless local area network (WLAN), a gateway device provides WLAN signals to stations (STAs) so they can access the network. As the performance and functionality of gateway devices increase, their power consumption becomes a significant issue.

[0003] In related art, there is a control method for a gateway device that includes multiple radio frequency circuits. In this control method, when a preset shutdown condition is met, the gateway device shuts down the radio frequency circuit corresponding to a first frequency band and keeps the radio frequency circuit corresponding to a second frequency band enabled. When a preset enable condition is met, the radio frequency circuit corresponding to the first frequency band is then enabled. This reduces the power consumption of the radio frequency circuit corresponding to the first frequency band, thereby reducing the power consumption of the gateway device.

[0004] However, this control method controls the radio frequency circuit of the first frequency band as a whole, which has a significant impact on the service transmission quality of the STA associated with the gateway device. Summary of the Invention

[0005] This application provides a control method, apparatus, device, chip, and system for a gateway device, which can perform energy-saving control on the gateway device with minimal impact on service quality. The technical solution adopted is as follows:

[0006] In a first aspect, a control method for a gateway device is provided. The control method can be executed by the gateway device. The gateway device includes at least two radio frequency circuits. The at least two radio frequency circuits include a first radio frequency circuit and a second radio frequency circuit. The control method includes: when first operating status information of the gateway device meets a channel operation condition of the first radio frequency circuit, and when the second radio frequency circuit is enabled, enabling or disabling some radio frequency channels of the first radio frequency circuit.

[0007] When the second RF circuit is enabled, some RF channels of the first RF circuit are enabled or disabled. That is, at least one RF channel of the first RF circuit is enabled simultaneously with the second RF circuit. This allows energy conservation by disabling some RF channels of the first RF circuit. Furthermore, when some RF channels of the first RF circuit are disabled, services are provided to STAs using the remaining RF channels of the first RF circuit to meet their service needs, thus minimizing the impact on STA service quality.

[0008] The second radio frequency circuit is turned on, which means that some radio frequency channels of the second radio frequency circuit are turned on, or all radio frequency channels are turned on.

[0009] Optionally, closing some RF channels of the first RF circuit includes: closing a first target number of RF channels with the worst signal quality in the first RF circuit based on signal quality parameters of each RF channel of the first RF circuit, wherein the first target number is a positive integer and is less than the number of RF channels included in the first RF circuit. Closing the first target number of RF channels with the worst signal quality and retaining the RF channels with good signal quality is beneficial to improving the service quality for the STA associated with the first RF circuit.

[0010] In a possible implementation, the first target quantity is a set value. In this implementation, the implementation logic of the control method is relatively simple.

[0011] In another possible implementation, the first target number is a dynamic value. In this case, the control method further includes: determining the first target number based on the second operating status information of the gateway device before shutting down some of the RF channels of the first RF circuit. In this implementation, dynamically determining the number of RF channels to be shut down based on the second operating status information of the gateway device can minimize the impact on services.

[0012] Optionally, the first working status information includes multiple parameters, and the second working status information includes at least one parameter (i.e., the reference parameter below). The parameter type contained in the second working status information may be completely identical, partially identical, or completely different from the parameter type contained in the first working status information.

[0013] Optionally, the second operating state information includes at least one reference parameter. The first target number can be determined by determining the number of radio frequency channels corresponding to the reference parameter range to which the at least one reference parameter belongs as the first target number based on a correspondence between the reference parameter range and the number of radio frequency channels. During implementation, the type of reference parameter can be set as needed, and the first target number can be determined based on the correspondence. In this way, an appropriate number of radio frequency channels can be shut down in different operating states of the gateway device, providing flexibility and reducing the impact on services.

[0014] In the case of closing part of the radio frequency channels of the first radio frequency circuit, the channel operation condition includes a channel closing condition, and the channel closing condition includes the following condition 1.

[0015] Condition 1: The data flow of the target link of the gateway device is less than or equal to the first flow threshold, and the target link includes one or both of an upstream link and a downstream link.

[0016] When the first condition is met, it indicates that the amount of business data currently transmitted by the gateway device is small, and the demand for data transmission rate or bandwidth is small. After closing some RF channels of the first RF circuit, it is highly likely that the remaining RF channels can meet the business needs of the STA. Therefore, closing some RF channels of the first RF circuit has little impact on the business quality of the STA associated with the working frequency band of the first RF circuit.

[0017] Optionally, the channel closing condition also includes one or more of the following conditions two to ten.

[0018] Condition 2: The service data transmitted by the gateway device is not a high-priority service or a non-target service type. Meeting this condition indicates that the gateway device currently has no high-priority or target service type services and has low data transmission rate or bandwidth requirements. Therefore, shutting down some RF channels of the first RF circuit has little impact on the service quality of STAs associated with the operating frequency band of the first RF circuit.

[0019] Condition three: The received signal strength indication (RSSI) of the STA associated with the operating frequency band of the first RF circuit is greater than or equal to the first RSSI threshold. Meeting this condition three indicates that the signal strength of the STA associated with the operating frequency band of the first RF circuit is large, that is, it is close enough to the gateway device. After shutting down some RF channels of the first RF circuit, the remaining RF channels can still provide services for the STA. Therefore, shutting down some RF channels of the first RF circuit has little impact on the service quality of the STA associated with the operating frequency band of the first RF circuit.

[0020] Condition 4: The number of STAs associated with the gateway device in the operating frequency band of the first radio frequency circuit is equal to 0, or the number of STAs associated with the gateway device in the operating frequency band of the first radio frequency circuit is greater than 0 and less than or equal to the first number threshold. Meeting this condition 4 indicates that the number of STAs associated with the gateway device in the operating frequency band of the first radio frequency circuit is small, and only some radio frequency channels are sufficient to serve these STAs. Therefore, some radio frequency channels of the first radio frequency circuit can be closed.

[0021] Condition 5: The number of STAs associated with the gateway device in the operating frequency band of the second RF circuit is equal to 0, or the number of STAs associated with the gateway device in the operating frequency band of the second RF circuit is greater than 0 and less than or equal to the second number threshold, and the RSSI of STAs associated with the gateway device in the operating frequency band of the second RF circuit is less than or equal to the second RSSI threshold. Meeting this condition 5 indicates that the operating frequency band of the second RF circuit is not associated with STAs, or the number of associated STAs is small and the distance between them is large. In this case, there is no need to use the first RF circuit to provide services to STAs.

[0022] Condition six: The RSSI of the STA associated with the working frequency band of the second radio frequency circuit of the gateway device is greater than the third RSSI threshold, the traffic of the STA associated with the working frequency band of the second radio frequency circuit is less than the second traffic threshold, and the service data transmitted by the STA associated with the working frequency band of the second radio frequency circuit belongs to non-high priority services or non-target service types. Meeting this condition six means that the signal strength of the STA associated with the working frequency band of the second radio frequency circuit is large, and the traffic of the STA is small, and there is no service with high latency requirements. In this case, even if the STA does not switch to the first radio frequency circuit, the second radio frequency circuit can meet its service needs. Therefore, some radio frequency channels of the first radio frequency circuit can be closed.

[0023] Condition 7: The signal to interference plus noise radio (SINR) of the operating frequency band of the first radio frequency circuit is greater than or equal to a first SINR threshold, or the interference duty cycle is less than or equal to a first interference duty cycle threshold. Meeting condition 7 indicates that the air interface quality of the operating frequency band of the first radio frequency circuit is good, and shutting down some radio frequency channels of the first radio frequency circuit has little impact on services.

[0024] Condition 8: The duration of no new STA access to the gateway device is greater than or equal to the duration threshold. Meeting condition 8 indicates a relatively stable network environment. Disabling some RF channels of the first RF circuit in a stable network environment can avoid frequent opening and closing of RF channels.

[0025] Condition 9: The number of different STAs whose probe requests are detected by the gateway device during the first monitoring period is less than or equal to the third threshold. Meeting Condition 9 indicates that the number of STAs near the gateway device during the first monitoring period is small and the network environment is simple. In this case, shutting down some RF channels of the first RF circuit can reduce the possibility of frequent opening and closing of RF channels.

[0026] Condition 10: The data traffic of the target link of other gateway devices within the set range around the gateway device is less than or equal to the third traffic threshold, the service data transmitted by the other gateway devices belongs to non-high priority services or non-target service types, and the RSSI of the STA associated with the other gateway devices is greater than or equal to the fourth RSSI threshold. If condition 10 is met, it means that the possibility of STA roaming from other gateway devices to this gateway device is small, or the STA roaming from other gateways to this gateway device has low requirements for data transmission rate, latency or bandwidth. Even if the first RF circuit of this gateway device closes the RF channel, it can still meet its service needs well. Therefore, some RF channels of the first RF circuit can be closed.

[0027] In one possible implementation, opening some of the radio frequency channels of the first radio frequency circuit includes opening all closed radio frequency channels of the first radio frequency circuit. In this case, the maximum data transmission capacity of the first radio frequency circuit can be restored as quickly as possible, ensuring service quality for STAs associated with the operating frequency band of the first radio frequency circuit.

[0028] In another possible implementation, enabling some of the RF channels of the first RF circuit includes: determining a second target number of RF channels to be enabled based on the third operating state information of the gateway device; and enabling at least some of the disabled RF channels of the first RF circuit according to the second target number. In this implementation, determining the second target number of RF channels to be enabled based on actual needs helps further improve energy conservation.

[0029] Optionally, the third working status information includes at least one parameter, and the type of the parameter included in the third working status information may be completely identical, partially identical, or completely different from the type of the parameter included in the second working status information.

[0030] In the case of enabling some RF channels of the first RF circuit, the channel operation condition includes a channel enabling condition. Optionally, the channel enabling condition includes one or more of the following conditions A to I.

[0031] Condition A: The data traffic of the target link of the gateway device is greater than the fourth traffic threshold. If condition A is met, the data traffic of the target link of the gateway device is high, and the enabled RF channels may not be sufficient to meet the service needs of the STA. Therefore, at least one of the disabled RF channels in the first RF circuit may be enabled.

[0032] Condition B: The service data transmitted by the gateway device belongs to high-priority services or target services. High-priority services and target services require larger bandwidth for data transmission or lower latency requirements. Therefore, at least one closed RF channel in the first RF circuit must be opened to meet the service needs of the STA.

[0033] Condition C: The RSSI of the STA associated with the gateway device in the operating frequency band of the first radio frequency circuit is less than the fifth RSSI threshold. If condition C is met, the STA is far from the gateway device. Therefore, it is necessary to open at least one of the closed radio frequency channels of the first radio frequency circuit to expand the signal coverage of the first radio frequency circuit and provide better service to the STA.

[0034] Condition D: The RSSI of the STA associated with the gateway device in the operating frequency band of the second RF circuit is greater than the sixth RSSI threshold. Meeting condition D indicates that the STA is close enough to the gateway device to switch to the first RF circuit. Therefore, it is necessary to open at least one of the closed RF channels of the first RF circuit.

[0035] Condition E: The traffic of the site associated with the working frequency band of the second radio frequency circuit of the gateway device is greater than the fifth traffic threshold, or the service data transmitted by the site associated with the working frequency band of the second radio frequency circuit of the gateway device belongs to a high-priority service or a target service type. When condition E is met, it means that the STA associated with the second radio frequency circuit of the gateway device has high requirements for bandwidth and / or data transmission rate. If it switches to the first radio frequency circuit, the first radio frequency circuit may not be able to meet its service needs if only some radio frequency channels are turned on. Therefore, it is necessary to turn on at least one of the radio frequency channels that have been closed by the first radio frequency circuit, so that the first radio frequency circuit can meet its service needs after at least one of the radio frequency channels that have been closed by the first radio frequency circuit is switched to the first radio frequency circuit.

[0036] Condition F: The SINR of the gateway device in the operating frequency band of the first RF circuit is less than the second SINR threshold, or the interference duty cycle is greater than the second interference duty cycle threshold. If condition F is met, the signal quality of the gateway device in the operating frequency band of the first RF circuit is poor, and additional RF channels of the first RF channel need to be enabled to ensure service quality.

[0037] Condition G: The gateway device receives a connection-related request from a STA. If condition G is met, it indicates that a STA may be searching for a previously connected network and will initiate a connection upon finding it. This means that there is a possibility that the STA needs to associate with the first RF circuit. Therefore, at least one RF channel of the first RF circuit can be enabled.

[0038] Condition H: The number of different STAs whose probe requests the gateway device detects during the second monitoring period is greater than the fourth quantity threshold. Meeting this condition H indicates that the network environment in which the gateway device is located is complex and has a large number of STAs. Therefore, at least one RF channel that was previously disabled by the first RF circuit can be enabled, which helps ensure service quality for each STA.

[0039] Condition I: the data traffic of the target link of other gateway devices within the set range around the gateway device is greater than the fourth traffic threshold, or the service data transmitted by the other gateway devices belongs to high-priority services or target service types, or the RSSI of the STA associated with the other gateway devices is less than or equal to the sixth RSSI threshold. If condition I is met, it means that the STA associated with other gateway devices near the gateway device has high-priority services or a large amount of transmitted data, or is more likely to roam to the gateway device. If the STA roams to the gateway device, it may need to access the first RF circuit. At this time, the RF channel of the first RF circuit that has been closed can be opened in advance to prepare for the STA service in advance.

[0040] Optionally, the frequency of the operating frequency band of the first RF circuit is greater than the frequency of the operating frequency band of the second RF circuit, or the frequency of the operating frequency band of the first RF circuit is less than the frequency of the operating frequency band of the second RF circuit.

[0041] Optionally, the method further includes: receiving a configuration instruction, the configuration instruction being used to indicate whether it is allowed to shut down at least part of the radio frequency channels of the first radio frequency circuit. Through the configuration instruction, the function of the gateway device to shut down part of the radio frequency channels of the radio frequency circuit can be turned on or off. By turning off this function, the gateway device can be prevented from frequently executing the judgment action of whether the channel operation conditions are met, which can further reduce the power consumption of the gateway device. Optionally, the configuration instruction is generated based on the total load information of the network where the gateway device is located. The total load information includes but is not limited to the number of STAs associated with all gateway devices in the network where the gateway device is located, and the traffic of the target link of the master device.

[0042] In a second aspect, a control device for a gateway device is provided. The control device has the function of implementing the method described in the first aspect. The function can be implemented by hardware or by hardware executing corresponding software. The hardware or software includes one or more modules corresponding to the above functions.

[0043] In a third aspect, a communication device is provided, comprising a processor and a communication interface, wherein the communication interface is connected to the processor, wherein the processor is used to implement any one of the methods provided in the first aspect.

[0044] Optionally, there are one or more processors, and the processor is a multi-core processor, and there are one or more memories.

[0047] Optionally, the memory may be integrated with the processor, or the memory may be provided separately from the processor.

[0048] In the specific implementation process, the memory can be a non-transitory memory, such as a read-only memory (ROM), which can be integrated on the same chip as the processor or be set on different chips. This application does not limit the type of memory and the setting method of the memory and the processor.

[0049] In a fourth aspect, a communication system is provided, which includes multiple gateway devices, which are communicatively connected, and any one of the multiple gateway devices is used to implement any one of the methods provided in the first aspect.

[0050] Optionally, the communication system is a fiber to the room (FTTR) system, and the multiple gateway devices include a master device and at least one slave device, and the master device and the at least one slave device are connected via an optical fiber.

[0051] In a fifth aspect, a computer-readable storage medium is provided, in which a software program is stored. When the software program is read and executed by one or more processors, it can implement any one of the methods provided in the first aspect.

[0061] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0062] Figure 1 This is a diagram of the fiber to the home or fiber to the office (FTTH / O) system architecture. Figure 1 As shown, the OLT connects to upstream network-side equipment (such as switches and routers) and to downstream optical network units (ONUs) via the optical distribution network (ODN). The ODN includes passive optical splitters for optical power distribution, trunk optical fibers connected between the passive optical splitters and the OLT, and branch optical fibers connected between the passive optical splitters and the ONUs. When transmitting downstream signals, the downstream signals sent by the OLT are transmitted to each ONU via the optical splitter. The ONU selectively receives the downstream data within the downstream signal that belongs to it. When transmitting upstream signals, the upstream signals sent by multiple ONUs are combined by the optical splitter into a single optical signal that is transmitted to the OLT. The ONU is also called an optical network terminal (ONT).

[0063] Building on FTTH / O, to address signal coverage issues within home or office networks (e.g., WLAN signals), optical fiber can be extended further into the home. Optical terminals providing WLAN signals are installed inside the home, shortening the distance between user terminals and wireless access points (APs), improving signal quality. This technology is known as FTTR.

[0064] Figure 2 This is a schematic diagram of the FTTR system architecture. Figure 2 As shown in the figure, the OLT in FTTH / O is deployed in a central equipment room, while the ONU is deployed in homes or offices. The master device in an FTTR network serves as both an ONU in the FTTH network and an upstream device for FTTR slave devices, managing them. Slave devices in an FTTR network can be deployed in various rooms in a home or office. Slave devices have both ONU and AP functions, providing WLAN signals to STAs. Both the master and slave devices connect to STAs through the user network interface (UNI).

[0065] Multiple slave devices can be deployed in an FTTR network, each connected to a master device via optical fiber or Ethernet cable. The master device centrally manages and configures all slave devices. The master device can also be called a "master gateway," "master optical modem," or "main FTTR unit (or main fiber unit, MFU)." Slave devices can also be called "slave gateway," "slave optical modem," or "sub FTTR unit (or sub fiber unit, SFU)."

[0066] Optionally, the STA can be any type of terminal device, including but not limited to mobile phones, laptops, tablet computers, wearable devices, etc. Wearable devices include but are not limited to smart watches, smart bracelets, virtual reality (VR) glasses, or VR helmets.

[0067] Figure 2 In the example, the master device is connected to two slave devices, namely slave 1 and slave 2. However, the embodiments of the present application do not limit the number of slave devices connected to the master device; for example, there can be more than two, or only one. The following description uses a gateway device as a master or slave device in an FTTR network as an example to illustrate the control method for a gateway device provided in the embodiments of the present application. However, the control method can also be applied to other gateway devices, such as any gateway device in a wireless network.

[0068] In an embodiment of the present application, both the master device and the slave device can have the function of an AP to provide a WLAN signal for the STA. In addition, the master device and / or the slave device include at least two radio frequency circuits. The at least two radio frequency circuits include a first radio frequency circuit and a second radio frequency circuit, the operating frequency band of the first radio frequency circuit is a first frequency band, and the operating frequency band of the second radio frequency circuit is a second frequency band. Here, the operating frequency band refers to the frequency band currently used by the radio frequency circuit for communication. During implementation, a radio frequency circuit can support one or more frequency bands, and the operating frequency band of the radio frequency circuit is one of the frequency bands supported by the radio frequency circuit. When the frequency band supported by the radio frequency circuit includes multiple sub-bands, the operating frequency band of the radio frequency circuit can be one of the multiple sub-bands.

[0069] In a possible implementation manner, the first radio frequency circuit and the second radio frequency circuit support different frequency bands. Correspondingly, the first frequency band and the second frequency band are different.

[0070] In some examples, the frequency of the first frequency band is less than the frequency of the second frequency band. For example, the first frequency band is the 2.4 GHz frequency band and the second frequency band is the 5 GHz frequency band. Alternatively, the first frequency band is the 2.4 GHz frequency band and the second frequency band is the 6 GHz frequency band.

[0071] In other examples, the frequency of the first frequency band is greater than the frequency of the second frequency band. For example, the first frequency band is a 5 GHz frequency band and the second frequency band is a 2.4 GHz frequency band. Alternatively, the first frequency band is a 6 GHz frequency band and the second frequency band is a 2.4 GHz frequency band.

[0072] In another possible implementation, the first RF circuit and the second RF circuit support the same frequency band, and the frequency band includes multiple sub-bands, and the first frequency band and the second frequency band are different sub-bands within the frequency band. For example, the first RF circuit and the second RF circuit both support the 5 GHz frequency band, the first frequency band is the 5.2 GHz frequency band, and the second frequency band is the 5.8 GHz frequency band.

[0073] Optionally, the at least two radio frequency circuits may further include a third radio frequency circuit, and the operating frequency band of the third radio frequency circuit is a third frequency band. The third frequency band, the first frequency band, and the second frequency band may be different.

[0074] Exemplarily, the frequency band supported by the third RF circuit is different from that of the first RF circuit and the second RF circuit. Accordingly, the third frequency band, the first frequency band, and the second frequency band may be different. For example, the first frequency band is the 2.4 GHz frequency band, the second frequency band is the 5 GHz frequency band, and the third frequency band is the 6 GHz frequency band. Alternatively, the frequency band supported by the third RF circuit is the same as the frequency band supported by the first RF circuit and / or the second RF circuit. For example, the frequency band supported by the first RF circuit and the first frequency band are both the 2.4 GHz frequency band, the frequency band supported by the second RF circuit and the third RF circuit are both the 5 GHz frequency band, the second frequency band is the 5.2 GHz frequency band, and the third frequency band is the 5.8 GHz frequency band.

[0075] Optionally, at least one RF circuit includes at least two RF channels, also known as a radio chain. The RF channel refers to the complete signal chain from baseband processing to antenna radiation, including hardware components such as digital-to-analog converters, power amplifiers, filters and antennas.

[0076] The gateway device can open multiple radio frequency circuits at the same time, and STAs can transmit service data through any of the multiple radio frequency circuits.

[0077] Figure 3 This is a schematic diagram illustrating the signal coverage of a gateway device provided in an embodiment of the present application. The gateway device includes a first RF circuit and a second RF circuit. The first RF circuit operates in the 5 GHz band, and the second RF circuit operates in the 2.4 GHz band. The first RF circuit includes two RF channels, and the second RF circuit includes two RF channels. Figure 3 The dashed line in the figure represents the signal coverage range of the first RF circuit, and the solid line represents the signal coverage range of the second RF circuit. When both RF channels of the first RF circuit and both RF channels of the second RF circuit are operating simultaneously, the signal coverage range of the second RF circuit is greater than that of the first RF circuit. When both RF channels of the second RF circuit are operating simultaneously, and one RF channel of the first RF circuit is operating while the other is not, the signal coverage range of the first RF circuit decreases, as indicated by the dashed line in the figure.

[0078] Figure 3 Taking the example of closing the RF channel of the first RF circuit with a higher working frequency band, where the second RF circuit with a lower working frequency band has a larger coverage range, as an example, in other embodiments, the maximum coverage range of the first RF circuit with a higher working frequency band can be made greater than the coverage range of the second RF circuit with a lower working frequency band (for example, increasing the number of RF channels of the first RF circuit, etc.), and closing the RF channel of the second RF circuit with a lower working frequency band.

[0079] Higher operating frequencies increase the power consumed by the corresponding RF circuits, leading to greater gateway device capacity and faster data transmission speeds. However, this also reduces the RF circuit's signal coverage. Therefore, higher operating frequency bands are typically used to provide high-capacity, high-speed communication services to STAs and consume more energy. Lower operating frequency bands consume less power and have wider signal coverage, primarily providing basic communication services to users.

[0080] In related technologies, the RF circuit corresponding to a certain frequency band is usually used as a unit to control the opening or closing of the RF circuit corresponding to the frequency band. If a STA is connected to the RF circuit of a certain frequency band before the RF circuit of the frequency band is turned off, the STA needs to be switched to the RF circuit of another frequency band first, but this may cause the STA to be disconnected, affecting the service quality of the STA. After turning off the RF circuit of the frequency band, if a STA needs to transmit data through the RF circuit of the frequency band later, it is necessary to turn on the RF circuit of the frequency band first and then connect to the STA. The delay is large, which affects the service quality of the STA.

[0081] To this end, an embodiment of the present application provides a control method for a gateway device. This control method enables or disables some RF channels of the first RF circuit when the first operating state information of the gateway device meets the channel operating conditions of the first RF circuit and the second RF circuit is enabled, thereby minimizing the impact on service quality while saving energy.

[0082] In the embodiment of the present application, closing the radio frequency channel may refer to disconnecting the radio frequency channel from the power supply, and opening the radio frequency channel may refer to connecting the radio frequency channel to the power supply.

[0083] Figure 4 Schematic diagram of a method for controlling a gateway device provided in an embodiment of the present application. The method is used to control a gateway device, which may be any device capable of providing AP services, for example, Figure 2 The master device or any slave device in Figure 2 Other gateway devices other than the master device and slave device in the system. Figure 4 As shown, the control method includes:

[0084] In step 401, it is determined whether a channel closing condition of a first radio frequency circuit is met according to first working state information of a gateway device.

[0085] If the first working state information satisfies the channel closing condition, then step 402 is executed. If the first working state information does not satisfy the channel closing condition, then the process returns to step 401.

[0086] The first working status information includes one or more of service information, signal quality information, load information and information of a device to be associated.

[0087] Optionally, the service information includes one or more of data traffic, service priority, and service type of the gateway device.

[0088] The data traffic of a gateway device includes the data traffic of its upstream and / or downstream links. The data traffic can be the average or maximum data traffic within a target time period. The length of the target time period can be set as needed. A longer target time period is more sensitive to data traffic fluctuations; a shorter target time period is more sensitive to data traffic fluctuations. The length of the target time period can be set as needed and is not limited in this embodiment of the present application. In implementation, the target time period can be between 1 and 20 minutes, for example, 1, 2, or 5 minutes. The upstream link refers to the link connecting the gateway device to the upstream device. When the gateway device is a slave device, the upstream link can be an optical, wireless, or network link connecting to the master device. When the gateway device is a master device, the upstream link is the optical link connecting the gateway device to the OLT. The downstream link refers to the link connecting the gateway device to the downstream device. In this embodiment of the present application, it is a WLAN link (i.e., a wireless link). The gateway device can monitor the data traffic of the target link in real time.

[0089] Service priorities can be divided based on latency requirements. Services with higher latency requirements have higher priority, while services with lower latency requirements have lower priority. In some examples, services can be divided into high-priority services and low-priority services (also known as low-priority services). For example, services such as live streaming, gaming, and video calls have high latency requirements and are therefore considered high-priority services.

[0090] The service type is used to indicate the service type of the service data transmitted by the STA associated with the gateway device, including but not limited to live broadcast, games, video calls, instant messaging, and web browsing.

[0091] The signal quality information is used to indicate the signal quality of the WLAN signal provided by the gateway device. The signal quality information includes one or more of the following signal quality parameters: SINR and interference duty cycle. Among them, SINR refers to the ratio of the strength of the received useful signal to the strength of the received interference signal (noise and interference). The interference duty cycle refers to the ratio of the duration that the interference signal occupies the target frequency band to the duration per unit time. The target frequency band refers to the operating frequency band of the first radio frequency circuit. The signal quality parameters can be measured by the STA and reported to the gateway device. The duration per unit time can be set according to actual needs, and the embodiments of the present application do not impose any restrictions on this.

[0092] The load information is used to indicate the information of the associated devices of each working frequency band. The load information may include the number of STAs associated with each working frequency band and the RSSI, etc. Here, the device associated with the working frequency band refers to the STA that establishes a communication connection with the gateway device through the radio frequency circuit corresponding to the working frequency band. Among them, the number of STAs associated with each working frequency band can be obtained by counting the number of STAs by the gateway device. The RSSI of the STA can be obtained by the gateway device evaluating the uplink message sent by the STA. Alternatively, the RSSI of the STA can be that the STA evaluates the downlink message sent by the gateway device and reports it to the gateway device after obtaining the RSSI. The embodiment of the present application does not limit the way in which the gateway device evaluates the uplink message to obtain the RSSI and the way in which the STA evaluates the downlink message.

[0093] RSSI is used to measure the signal strength received by a wireless communication device. The RSSI value can be expressed as a negative value, and the unit is decibel milliwatt (dBm). The larger the RSSI value (for example, the closer it is to 0), the stronger the signal, and the smaller the RSSI value (for example, the closer it is to -100), the weaker the signal. The RSSI can be the last RSSI in the monitoring period, the average RSSI of all RSSIs in the monitoring period, the minimum RSSI of all RSSIs, or the statistical value of all RSSIs in the monitoring period. The calculation method of the RSSI statistical value can be selected as needed, and the embodiment of the present application does not limit this. For example, the statistical value can be the maximum RSSI value among the RSSI values ​​in the monitoring period that exceed the proportion threshold. The length of the monitoring period can be set as needed, and the embodiment of the present application does not limit this. For example, the length of the monitoring period can be 30s-10 minutes.

[0094] The RSSI value can be used to estimate the distance between a STA and a gateway. A larger RSSI value indicates a closer distance, while a smaller RSSI value indicates a greater distance. When the RSSI value changes less than the threshold, the STA's position remains essentially unchanged. A decreasing RSSI value indicates that the STA is moving away from the gateway; an increasing RSSI value indicates that the STA is approaching the gateway.

[0095] The device information to be associated is used to indicate the number of STAs to be associated. For example, the device information to be associated includes the number of different MAC addresses to which probe requests are detected by the gateway device during the target time period, which can be counted by the gateway device. Since a MAC address can uniquely represent a STA, the number of different MAC addresses is equal to the number of STAs to be associated. The STA will periodically send probe requests on various channels in various frequency bands to scan for wireless networks. When the gateway device receives the probe request, it will return a probe response to inform the wireless network information it provides. Based on the wireless network information in the probe response, the STA will prioritize the gateway device with a stronger signal and a previous connection for association. If there is no previously connected gateway device, the gateway device will be selected for association according to the user's instructions.

[0096] Optionally, the length of the target time period can be set according to actual needs, for example, 30 seconds to 10 minutes. Exemplarily, the length of the target time period can be 1 minute, 2 minutes, 3 minutes, 5 minutes, or 10 minutes. The longer the target time period, the lower the sensitivity to quantity fluctuations, and the shorter the target time period, the higher the sensitivity to quantity fluctuations.

[0097] The content (or parameter type) of the first working state information is related to the specific conditions included in the channel operating conditions below.

[0098] Exemplarily, the channel closing conditions may include the following conditions one to three.

[0099] Condition 1: The data flow of the target link of the gateway device is less than or equal to the first flow threshold. The target link includes one or both of an upstream link and a downstream link.

[0100] The first traffic threshold can be set as needed. In some examples, the first traffic threshold can be a fixed value, such as 100 kbps, 1 Mbps, or 10 Mbps. In other examples, the first traffic threshold can be a dynamic value. The dynamic value can be related to a network quality parameter, including at least one of packet loss rate, RSSI, or interference level (such as SINR or interference duty cycle). For example, the dynamic value is related to RSSI, and the first traffic threshold corresponding to the first RSSI range is greater than the first traffic threshold corresponding to the second RSSI range, where the RSSI value in the first RSSI range is greater than the RSSI value in the second RSSI range.

[0101] Optionally, the first traffic threshold when the target link is an upstream link, the first traffic threshold when the target link is a downstream link, and the first traffic threshold when the target link includes an upstream link and a downstream link can be the same, for example, all are 1Mbps or 10Mbps.

[0102] Alternatively, the first traffic threshold when the target link is an upstream link, the first traffic threshold when the target link is a downstream link, and the first traffic threshold when the target link includes an upstream link and a downstream link may be different. For example, the first traffic threshold when the target link is an upstream link and the first traffic threshold when the target link is a downstream link are the same, that is, 1 Mbps, and the first traffic threshold when the target link includes an upstream link and a downstream link is 2 Mbps. When the target link includes an upstream link and a downstream link, the data traffic of the target link is the sum of the data traffic of the upstream link and the data traffic of the downstream link.

[0103] Meeting the first condition indicates that the data traffic of the target link of the gateway device is small. In this case, shutting down some radio frequency channels of the first radio frequency circuit has little impact on the service.

[0104] Condition 2: The service data transmitted by the gateway device is non-high-priority or non-target service type. The service priority of the target service type is higher than that of the non-target service type, or the latency requirement of the target service type is higher than that of the non-target service type (i.e., the maximum allowable latency of the target service type is lower than that of the non-target service type).

[0105] If the second condition is met, it means that there is no service with high latency requirements. In this case, shutting down some radio frequency channels of the first radio frequency circuit will have little impact on the service.

[0106] Condition 3: The RSSI of the STA associated with the gateway device in the operating frequency band of the first radio frequency circuit is greater than or equal to a first RSSI threshold. That is, the RSSI of the STA associated with the first radio frequency circuit is greater than or equal to the first RSSI threshold. The first RSSI threshold can be set as needed and is not limited in this embodiment of the present application. Optionally, the value range of the first RSSI threshold is -55dBm to -70dBm.

[0107] In some examples, the first RSSI threshold can be a fixed value, such as -60dBm. In other examples, the first RSSI threshold takes different values ​​in different time periods. In the first time period, the first RSSI threshold is the first value, and in the second time period, the first RSSI threshold is the second value. The first time period and the second time period can be divided according to the user's activity level, and the time period with higher user activity has a larger RSSI threshold. For example, the first time period is 06:00-00:00 (daytime and evening), and the second time period is 00:00 to 06:00 (late night). The first value is -55dBm and the second value is -70dBm.

[0108] The third condition is satisfied, indicating that the RSSI of the STA associated with the working frequency band of the first radio frequency circuit is large. Accordingly, the distance between the STA and the gateway device is close, and shutting down some radio frequency channels of the first radio frequency circuit has little impact on its services.

[0109] Optionally, the channel closing condition may also include one or more of the following conditions four to ten.

[0110] Condition 4: The number of STAs associated with the gateway device in the operating frequency band of the first radio frequency circuit is equal to 0, or the number of STAs associated with the gateway device in the operating frequency band of the first radio frequency circuit is greater than 0 and less than or equal to the first number threshold. In other words, the number of STAs associated with the first radio frequency circuit is equal to 0, or the number of STAs associated with the first radio frequency circuit is greater than 0 and less than or equal to the first number threshold.

[0111] The first quantity threshold can be set as needed. In some examples, the first quantity threshold is a fixed value, such as 1 or 2. In other examples, the first quantity threshold varies for different time periods. For example, the first quantity threshold for the first time period is lower than the first quantity threshold for the second time period, and the user activity level in the first time period is higher than the user activity level in the second time period. For example, if the first time period is 06:00-00:00 (daytime and evening) and the second time period is 00:00 to 06:00 (late night), the first quantity threshold for the first time period is 1, and the first quantity threshold for the second time period is 3.

[0112] If the fourth condition is met, it means that the number of STAs associated with the first radio frequency circuit is small, and only some radio frequency channels are sufficient to provide services for these STAs. Therefore, some radio frequency channels of the first radio frequency circuit can be closed.

[0113] Condition 5: The number of STAs associated with the gateway device in the operating frequency band of the second RF circuit is equal to 0, or the number of STAs associated with the gateway device in the operating frequency band of the second RF circuit is greater than 0 and less than or equal to the second number threshold, and the RSSI of the STAs associated with the gateway device in the operating frequency band of the second RF circuit is less than or equal to the second RSSI threshold. In other words, the number of STAs associated with the second RF circuit is equal to 0, or the number of STAs associated with the second RF circuit is greater than 0 and less than or equal to the second number threshold, and the RSSI of the STAs associated with the second RF circuit is less than or equal to the second RSSI threshold.

[0114] The second RSSI threshold can be set according to actual needs, for example, it can be -70dBm or -80dBm.

[0115] If condition five is met, it means that the working frequency band of the second RF circuit is not associated with a STA, or the number of associated STAs is small and the distance is far. In this case, there is no need to use the first RF circuit to provide services for the STA, so at least part of the RF channel of the first RF circuit can be closed.

[0116] Condition six: The RSSI of the STA associated with the gateway device in the working frequency band of the second radio frequency circuit is greater than the third RSSI threshold, the traffic of the STA associated with the working frequency band of the second radio frequency circuit is less than the second traffic threshold, and the service data transmitted by the STA associated with the working frequency band of the second radio frequency circuit belongs to non-high priority services or non-target service types.

[0117] Meeting condition six indicates that the STA signal strength associated with the operating frequency band of the second radio circuit is high, the STA's traffic is low, and there are no services with high latency requirements. In this case, even if the STA does not switch to the first radio circuit, the second radio circuit can still meet its service needs. Therefore, some radio channels of the first radio circuit can be shut down.

[0118] The third RSSI threshold may be greater than or equal to the second RSSI threshold. The third RSSI threshold may be set according to actual needs, and the embodiment of the present application does not limit this. For example, the third RSSI threshold may be -55dBm or -60dBm.

[0119] The second traffic threshold can be set as needed. In some examples, the second traffic threshold can be a fixed value, such as 100 kbps, 1 Mbps, or 10 Mbps. In other examples, the second traffic threshold can be a dynamic value. The dynamic value can be related to a network quality parameter, including at least one of packet loss rate, RSSI, or interference level (such as SINR or interference duty cycle). For example, the dynamic value is related to RSSI, and the second traffic threshold corresponding to the third RSSI range is greater than the second traffic threshold corresponding to the fourth RSSI range, where the RSSI value in the third RSSI range is greater than the RSSI value in the fourth RSSI range.

[0120] Optionally, the traffic of STAs associated with the operating frequency band of the second radio frequency circuit compared with the second traffic threshold is the traffic of all STAs associated with the operating frequency band of the second radio frequency circuit, and the second traffic threshold may be 5 Mbps, for example. Alternatively, the traffic of a single STA associated with the operating frequency band of the second radio frequency circuit is compared with the second traffic threshold. In this case, the second traffic threshold may be smaller, such as 1 Mbps, for example. Exemplarily, the second traffic threshold may be equal to or different from the first traffic threshold. For example, when the second traffic threshold is used to determine the traffic size of a single STA, the second traffic threshold is smaller than the first traffic threshold.

[0121] Condition seven: the SINR of the operating frequency band of the first radio frequency circuit is greater than or equal to the first SINR threshold, or the interference duty cycle is less than or equal to the first interference duty cycle threshold.

[0122] The first SINR threshold and the first interference duty cycle threshold can be set according to actual needs, and the embodiments of the present application do not limit this. Exemplarily, the value range of the first SINR threshold is 20dB-30dB, for example, 20dB or 25dB; the value range of the first interference duty cycle threshold is 10%-30%, for example, 10%, 20% or 30%.

[0123] When condition seven is met, it indicates that the air interface quality of the working frequency band of the first radio frequency circuit is good, and shutting down some radio frequency channels of the first radio frequency circuit has little impact on services.

[0124] Condition 8: The duration during which no new STA is connected to the gateway device is greater than or equal to the duration threshold.

[0125] If a new STA connects to the gateway device, it may switch between different RF circuit operating bands and, therefore, may transmit service data with the gateway device using the operating band of the first RF circuit. By setting condition seven, you can disable some RF channels of the first RF circuit when the network environment is relatively stable, reducing the frequent opening and closing of RF channels.

[0126] The duration threshold can be set as needed, for example, it can be 1 minute to 20 minutes. In some examples, the duration threshold can be a fixed value, for example, 1 minute, 2 minutes or 5 minutes. In other examples, the duration threshold can be a dynamic value. The value of the duration threshold is different in different time periods. Exemplarily, the duration threshold in the first time period is less than the duration threshold in the second time period, and the user activity level in the first time period is greater than the user activity level in the second time period. For example, the first time period is 06:00-00:00 (daytime and evening), the second time period is 00:00 to 06:00 (late night), the duration threshold in the first time period is 2 minutes, and the duration threshold in the second time period is 10 minutes.

[0127] Condition nine: During the first monitoring period, the number of different STAs to which probe requests are detected by the gateway device is less than or equal to a third number threshold.

[0128] A Media Access Control (MAC) address uniquely identifies a STA. Therefore, the number of different STAs to which the detected probe requests belong can be represented by the number of MAC addresses corresponding to the detected probe requests. If the number of different STAs to which the detected probe requests belong is less than or equal to the third threshold, it indicates that the number of STAs near the gateway device during the first monitoring period is small and the network environment is relatively simple. In this case, shutting down some RF channels of the first RF circuit can reduce the possibility of frequent opening and closing of RF channels.

[0129] The duration of the first monitoring period can be set as needed, and the embodiments of the present application do not impose any restrictions on this. When implemented, the duration of the first monitoring period can be 1 minute to 20 minutes. In some examples, the first monitoring period can be a fixed value, for example, 1 minute, 2 minutes, or 5 minutes. In other examples, the first monitoring period can be a dynamic value. The value of the first monitoring period is different in different time periods. For example, the duration of the first monitoring period in the first time period is less than the duration of the first monitoring period in the second time period, and the user activity level in the first time period is greater than the user activity level in the second time period. For example, the first time period is 06:00-00:00 (daytime and evening), and the second time period is 00:00 to 06:00 (late night). The duration of the first monitoring period in the first time period is 1 minute, and the duration of the first monitoring period in the second time period is 10 minutes.

[0130] Condition 10: The data traffic of the target links of other gateway devices within the set range around the gateway device is less than or equal to the third traffic threshold, the service data transmitted by other gateway devices belongs to non-high priority services or non-target service types, and the RSSI of the STA associated with the other gateway devices is greater than or equal to the fourth RSSI threshold.

[0131] In condition 10, the target link of the other gateway device may include at least one of an upstream link and a downstream link of the other gateway device. The other gateway devices within the set range may be all gateway devices in the access network, or some gateway devices in the access network. In some examples, one gateway device (e.g., a master device) may collect data traffic from the target links of all gateway devices and then send it to the other gateway devices.

[0132] The third traffic threshold can be set as needed. In some examples, the third traffic threshold can be a fixed value, such as 100kbps, 1Mbps, or 10Mbps. In other examples, the third traffic threshold can be a dynamic value. The dynamic value can be related to network quality parameters of other gateway devices, including at least one of packet loss rate, RSSI, or interference level (such as SINR or interference duty cycle). For example, the dynamic value is related to RSSI, and the third traffic threshold corresponding to the fifth RSSI range is greater than the third traffic threshold corresponding to the sixth RSSI range, wherein the RSSI value in the fifth RSSI range is greater than the RSSI value in the sixth RSSI range. Optionally, the third traffic threshold can be the same as or different from the aforementioned first traffic threshold. Exemplarily, the fourth RSSI threshold can be a fixed value, such as -60dBm.

[0133] If the data traffic of the target link of other gateway devices that are closer to the gateway device is large, or there is business data of the target business type or high-priority business, it means that the STA associated with the other gateway devices has high requirements for data transmission rate or delay. If it roams to this gateway device, this gateway device may need to use the first RF circuit to transmit the business data of the STA. In this case, if at least part of the RF channel of the first RF circuit is turned off, it may cause the transmission delay of the STA to increase after roaming, affecting its service quality. When condition ten is met, it means that the possibility of STA roaming from other gateway devices to this gateway device is small, or the STA roaming from other gateways to this gateway device has low requirements for data transmission rate, delay or bandwidth. Even if the RF channel of the first RF circuit of this gateway device is turned off, it can better meet its business needs.

[0134] During implementation, the above conditions one to ten can be combined arbitrarily according to the scenario or business needs.

[0135] Optionally, the channel closing condition is pre-set in the gateway device. For example, the channel closing condition can be pre-stored in the gateway device before the gateway device leaves the factory. For another example, the channel closing condition can be generated according to the user operation instruction before the gateway device executes the control method. The configuration device (the gateway device or the management device connected to the gateway device) can output a configuration interface to receive the user operation instruction. The first configuration interface has multiple first configuration options, each first configuration option is used to indicate one of the aforementioned conditions one to ten, and the user operation instruction is used to indicate one or more selected first configuration options. When a first configuration option is selected, it means that the channel closing condition includes the condition indicated by the first configuration option. The set of conditions corresponding to all selected configuration options is the aforementioned channel closing condition.

[0136] In step 402, when the second radio frequency circuit is turned on, at least one radio frequency channel in the first radio frequency circuit is turned off.

[0137] When the second radio frequency circuit is turned on, that is, some or all radio frequency channels of the second radio frequency circuit are kept in an turned-on state, the STA can transmit data through the second radio frequency circuit.

[0138] In one possible implementation, step 402 may include shutting down N RF channels with the worst signal quality in the first RF circuit based on signal quality parameters of each RF channel of the first RF circuit, where N is a positive integer and less than the number of RF channels included in the first RF circuit. In this implementation, shutting down the N RF channels with the worst signal quality and retaining RF channels with good signal quality helps improve the quality of service for STAs associated with the first RF circuit. Optionally, the signal quality parameters include, but are not limited to, SINR, RSSI, or signal-to-noise ratio (SNR).

[0139] During implementation, the RF channels in the first RF circuit can be sorted from best to worst based on their signal quality parameters. The penultimate to Nth-to-last RF channels are the N RF channels with the worst signal quality. For example, the first RF circuit contains three RF channels, and the signal quality parameters for these three channels are RSSI. The RSSI for the first RF channel is -60dBm, the RSSI for the second RF channel is -55dBm, and the RSSI for the third RF channel is -58dBm. As mentioned above, a larger RSSI value (for example, closer to 0) indicates a stronger signal and better signal quality. Sorting these three RF channels from best to worst signal quality results in the second RF channel, the third RF channel, and the first RF channel. Assuming N is 2, the two RF channels with the worst signal quality are the first and third RF channels. In this case, the first and third radio frequency channels are disabled, and the second radio frequency channel is retained.

[0140] In another possible implementation, N radio frequency channels may be randomly selected from the first radio frequency circuit to be shut down.

[0141] In some examples, N is a set value. For example, when the number of RF channels included in the first RF circuit is 2, N may be equal to 1.

[0142] In other examples, a first target number of RF channels to be disabled (i.e., the value of N) can be determined based on the second operating status information of the gateway device; then, the N RF channels in the first RF circuit are disabled. Dynamically determining the target number of RF channels to be disabled based on the second operating status information of the gateway device can minimize the impact on services.

[0143] Optionally, the second working state information includes at least one reference parameter. The reference parameter type contained in the second working state information may be completely identical, partially identical, or completely different from the parameter type contained in the first working state information. In some examples, the reference parameter type in the second working state information may be a subset of the parameter type in the first working state information. The type of reference parameter may include one or more of the following: the number of STAs associated with the first RF circuit, the RSSI of the STAs associated with the first RF circuit, the data traffic size of the first RF circuit, the SINR or interference duty cycle of the first RF circuit, etc.

[0144] During implementation, a correspondence between the reference parameter range and the number of RF channels may be preset; and then, based on the correspondence, the number of RF channels corresponding to the reference parameter range to which each reference parameter in the working status information belongs may be used as the aforementioned first target number.

[0145] When the reference parameter included in the second working state information of the gateway device is the number of STAs associated with the first RF circuit, in the corresponding relationship, the greater the number of STAs associated with the first RF circuit, the smaller the number of corresponding RF channels; conversely, the smaller the number of STAs associated with the first RF circuit, the larger the number of corresponding RF channels. This is because the greater the number of STAs associated with the first RF circuit, the higher the possibility that these STAs will generate business data transmission on the working frequency band of the first RF circuit, and more RF channels need to be reserved to serve these STAs.

[0146] When the reference parameter included in the second working status information of the gateway device is the RSSI of the STA associated with the first RF circuit, in the corresponding relationship, the larger the RSSI, the larger the number of corresponding RF channels, and conversely, the smaller the RSSI, the smaller the number of corresponding RF channels.

[0147] When the reference parameter included in the second working status information of the gateway device is the data flow rate of the working frequency band of the first radio frequency circuit, in the corresponding relationship, the greater the data flow rate, the smaller the number of corresponding radio frequency channels; conversely, the smaller the data flow rate, the larger the number of corresponding radio frequency channels.

[0148] When the reference parameter included in the second working status information of the gateway device is the SINR of the working frequency band of the first RF circuit, in the corresponding relationship, the greater the SINR of the working frequency band of the first RF circuit, the greater the number of corresponding RF channels; conversely, the smaller the SINR of the working frequency band of the first RF circuit, the smaller the number of corresponding RF channels.

[0149] When the reference parameter included in the second working status information of the gateway device is the interference duty cycle of the working frequency band of the first RF circuit, in the corresponding relationship, the greater the interference duty cycle of the working frequency band of the first RF circuit, the smaller the number of corresponding RF channels; conversely, the smaller the interference duty cycle of the working frequency band of the first RF circuit, the larger the number of corresponding RF channels.

[0150] When the reference parameters included in the second working status information of the gateway device include any two of the number of STAs associated with the first RF circuit, the RSSI of the STAs associated with the first RF circuit, the data traffic size of the first RF circuit, the SINR of the first RF circuit, or the interference duty cycle, the correspondence can be in the form of, for example, Table 1.

[0151] Table 1 Correspondence between reference parameter range and number of RF channels

[0152]

[0153] During implementation, reference parameter A and reference parameter B can be selected based on actual conditions. For example, reference parameter A can be the data traffic volume of the first RF circuit, and reference parameter B can be the RSSI of the STA associated with the first RF circuit. For another example, reference parameter A can be the data traffic volume of the first RF circuit, and reference parameter B can be the SINR or interference duty cycle of the first RF circuit.

[0154] When the reference parameters included in the second working status information of the gateway device include the number of STAs associated with the first RF circuit, the RSSI of the STA associated with the first RF circuit, the data traffic size of the first RF circuit, the SINR of the first RF circuit, or at least three of the interference duty cycle, the type of corresponding relationship is similar to that in Table 1 and is not described in detail here.

[0155] During implementation, the type of reference parameter can be set as needed, and the first target number can be determined based on the corresponding relationship. In this way, an appropriate number of RF channels can be closed under different working states of the first RF circuit, providing a certain degree of flexibility and reducing the impact on the business.

[0156] Optionally, Figure 4 The method shown can be performed when all RF channels of the first RF circuit are turned on, or when some RF channels of the first RF circuit are turned on and some RF channels are turned off.

[0157] Optionally, when at least part of the radio frequency channels of the first radio frequency circuit are closed (for example, Figure 4 The method shown turns off some RF channels of the first RF circuit, or, when the gateway device is started, only some RF channels of the first RF circuit are started by default and the other RF channels are kept closed). If the channel opening condition in the channel operation condition is met, some of the closed RF channels can also be turned on to meet the business needs of the STA.

[0158] The following combination Figure 5 The process of opening some RF channels of the first RF circuit is described. Figure 5 As shown, the opening process includes the following steps 501 to 502.

[0159] In step 501, it is determined whether a channel opening condition of a first radio frequency circuit is met according to first working state information of a gateway device.

[0160] If the first working state information meets the channel opening condition, step 502 is executed; if the first working state information does not meet the channel opening condition, the process returns to step 501 and keeps the RF channel of the first RF circuit closed in the closed state.

[0161] In step 502, when the second radio frequency circuit is turned on, at least one radio frequency channel among the closed radio frequency channels of the first radio frequency circuit is turned on.

[0162] In some embodiments, the closed radio frequency channels of the first radio frequency circuit are part of all radio frequency channels of the first radio frequency circuit. Figure 5 The method shown is only performed when some of the radio frequency channels of the first radio frequency circuit are turned off. If all radio frequency circuits of the first radio frequency circuit are turned on or off, the method does not need to be performed.

[0163] In other embodiments, the closed radio frequency channels of the first radio frequency circuit may be all radio frequency channels of the first radio frequency circuit or a portion thereof. Figure 5 The method shown is performed when there is a closed radio frequency channel of the first radio frequency circuit. If all radio frequency circuits of the first radio frequency circuit are in an open state, there is no need to perform the method.

[0164] When some of the RF channels of the first RF circuit are disabled and others are enabled, some components (such as modulators and demodulators) shared by the various RF channels of the first RF circuit remain operational. Therefore, when enabling at least one of the disabled RF channels of the first RF circuit while some of the channels are disabled, fewer components need to be enabled, and the process is faster than enabling the first RF circuit after the entire RF circuit is disabled.

[0165] Optionally, the channel opening conditions include one or more of the following conditions A to I.

[0166] Condition A: The data traffic of the target link of the gateway device exceeds the fourth traffic threshold. For details about the target link, see the aforementioned channel closing conditions.

[0167] Optionally, the fourth traffic threshold may be greater than or equal to the aforementioned first traffic threshold. When the fourth traffic threshold is greater than the first traffic threshold, repeated switching of the RF channel due to random fluctuations in traffic volume can be avoided. Exemplarily, the fourth traffic threshold may be the sum of the first traffic threshold and the first threshold increment. The first threshold increment may range from 1 Mbps to 10 Mbps. Exemplarily, the first threshold increment may be 1 Mbps or 5 Mbps, etc. Alternatively, the fourth traffic threshold may be a fixed value (i.e., it does not change with the first traffic threshold), for example, 10 Mbps.

[0168] If condition A is met, it means that the data traffic of the target link of the gateway device is large, and the open RF channels may not be sufficient to meet the service needs of the STA. Therefore, at least one of the closed RF channels in the first RF circuit can be opened.

[0169] Condition B: The service data transmitted by the gateway device belongs to high-priority services or target service types.

[0170] As mentioned above, high-priority services and target service types require larger bandwidth for data transmission or need to meet lower latency requirements. Therefore, when condition B is met, it is necessary to open at least one closed RF channel in the first RF circuit to meet the service needs of the STA.

[0171] Condition C: The RSSI of the STA associated with the gateway device in the operating frequency band of the first radio frequency circuit is less than the fifth RSSI threshold.

[0172] Optionally, the fifth RSSI threshold may be less than or equal to the first RSSI threshold. When the fifth RSSI threshold is less than the first RSSI threshold, repeated switching of the RF channel due to random fluctuations in RSSI can be avoided. The fifth RSSI threshold may be the sum of the first RSSI threshold and the second threshold increment. The second threshold increment may range from -10dBm to -1dBm. For example, the second threshold increment may be -10dBm or -5dBm. Alternatively, the fifth RSSI threshold may be a set value, as long as it is less than the first RSSI threshold, such as -70dBm.

[0173] When condition C is met, it indicates that the STA is far away from the gateway device. Therefore, it is necessary to open at least one of the closed RF channels of the first RF circuit to expand the signal coverage of the first RF circuit and provide better service for the STA.

[0174] Condition D: The RSSI of the STA associated with the gateway device in the operating frequency band of the second radio frequency circuit is greater than the sixth RSSI threshold.

[0175] Optionally, the sixth RSSI threshold may be a fixed value, and the value range of the sixth RSSI threshold may be -50 dBm or -60 dBm. For example, it may be -50 dBm.

[0176] If condition D is met, it means that the distance between the STA and the gateway device is close enough and it may be necessary to switch to the first radio frequency circuit. Therefore, it is necessary to open at least one of the closed radio frequency channels of the first radio frequency circuit.

[0177] Condition E: The traffic of the site associated with the gateway device in the working frequency band of the second radio frequency circuit is greater than the fifth traffic threshold, or the service data transmitted by the site associated with the working frequency band of the second radio frequency circuit of the gateway device belongs to high-priority service or target service type service.

[0178] When condition E is met, it means that the STA associated with the second RF circuit of the gateway device has high requirements for bandwidth and / or data transmission rate. If it switches to the first RF circuit, the first RF circuit may not be able to meet its business needs by only opening some RF channels. Therefore, it is necessary to open at least one of the RF channels that have been closed by the first RF circuit so that the first RF circuit can meet its business needs after at least one of the RF channels that have been closed by the first RF circuit is switched to the first RF circuit.

[0179] Optionally, the fifth traffic threshold may be greater than or equal to the aforementioned second traffic threshold. When the fifth traffic threshold is greater than the second traffic threshold, repeated switching of the RF channel due to random fluctuations in traffic volume can be avoided. Exemplarily, the fifth traffic threshold may be the sum of the second traffic threshold and the increment of the third threshold. The increment of the third threshold may range from 1 Mbps to 10 Mbps. Exemplarily, the increment of the third threshold may be 1 Mbps or 5 Mbps, etc. Alternatively, the fifth traffic threshold may be a fixed value (i.e., it does not change with the second traffic threshold), for example, 5 Mbps.

[0180] Condition F: The SINR of the gateway device in the working frequency band of the first radio frequency circuit is less than the second SINR threshold, or the interference duty cycle is greater than the second interference duty cycle threshold.

[0181] The second SINR threshold and the second interference duty cycle threshold can be set according to actual needs, and the embodiments of the present application do not limit this. For example, the second SINR threshold is less than or equal to the first SINR threshold. The second interference duty cycle threshold may be greater than or equal to the first interference duty cycle threshold. In this case, repeated switching of the RF channel due to random fluctuations in SINR or interference duty cycle can be avoided.

[0182] Exemplarily, the second SINR threshold may be the sum of the first SINR threshold and the SINR threshold increment. The SINR threshold increment may range from 0 to 5 dB. Exemplarily, the SINR threshold increment may be 2 dB or 5 dB, etc. Alternatively, the second SINR threshold may be a fixed value (i.e., does not change with the first SINR threshold), for example, 20 dB.

[0183] Exemplarily, the second interference duty cycle threshold may be the sum of the first interference duty cycle threshold and the duty cycle threshold increment. The duty cycle threshold increment may range from 0 to 10%. Exemplarily, the SINR threshold increment may be 5% or 8%, etc. Alternatively, the second interference duty cycle threshold may be a fixed value (i.e., it does not change with the first interference duty cycle threshold), such as 10%, 20%, 30%, or 35%, etc., as long as it is greater than or equal to the first interference duty cycle threshold.

[0184] When condition F is met, it indicates that the signal quality of the gateway device in the working frequency band of the first radio frequency circuit is poor, and it is necessary to increase the radio frequency channel opened by the first radio frequency channel to ensure service quality.

[0185] Condition G: The gateway device receives a connection-related request sent by the STA, such as a probe request, an authentication request, an association request, or a reassociation request.

[0186] When condition G is met, it means that a STA may be searching for a network it has previously connected to, and will initiate a connection after finding it. That is, there is a possibility that it needs to be associated with the first RF circuit. Therefore, at least one RF channel of the first RF circuit can be opened.

[0187] In some examples, it is assumed that a STA has been connected to the working frequency band of a first RF circuit but has not been connected to the working frequency band of a second RF circuit, and the first RF circuit and the second RF circuit of a gateway device have different service set identifiers (SSIDs). If some RF channels of the first RF circuit are in a closed state, and the signal coverage range of the first RF circuit at this time is smaller than the signal coverage range of the second RF circuit, when the gateway device receives a probe request from the STA through the second RF circuit and the RSSI of the STA indicates that the first RF circuit needs to open more RF channels in order for the signal of the first RF circuit to cover the STA, it is necessary to open at least one RF channel of the first RF circuit so that the signal of the first RF circuit can cover the STA and achieve normal access of the STA.

[0188] Condition H: The number of different STAs to which the probe requests detected by the gateway device in the second monitoring period belongs is greater than the fourth number threshold.

[0189] Optionally, the duration of the second monitoring period may be the same as or different from the length of the first monitoring period. For statistical purposes, the duration of the second monitoring period may be the same as the length of the first monitoring period.

[0190] Optionally, the fourth quantity threshold may be greater than or equal to the aforementioned third quantity threshold. When the fourth quantity threshold is greater than the third quantity threshold, repeated switching of the radio channel due to random fluctuations in the number of STAs can be avoided. The fourth quantity threshold may be the sum of the third quantity threshold and the fourth threshold increment, or the fourth quantity threshold may be a set multiple of the third quantity threshold. The fourth threshold increment may range from 1 to 5. For example, the fourth threshold increment may be 1, 2, or 3. Alternatively, the fourth quantity threshold may be a set value, as long as it is greater than or equal to the third quantity threshold.

[0191] Satisfying the condition H indicates that the network environment in which the gateway device is located is complex and the number of STAs is large. Therefore, at least one radio frequency channel whose first radio frequency circuit has been closed may be opened, which is conducive to ensuring the service quality of each STA.

[0192] Condition I: The data traffic of the target link of other gateway devices within the set range around the gateway device is greater than the sixth traffic threshold, or the service data transmitted by the other gateway devices is service data of the target service type, or the RSSI of the STA associated with the other gateway devices is less than or equal to the seventh RSSI threshold.

[0193] The sixth traffic threshold can be set as needed. In some examples, the sixth traffic threshold can be a fixed value, such as 100kbps, 1Mbps, or 10Mbps. In other examples, the third traffic threshold can be a dynamic value, which can be related to network quality parameters of other gateway devices. In some other examples, the sixth traffic threshold can be greater than or equal to the aforementioned third traffic threshold. For example, the fifth traffic threshold can be the sum of the second traffic threshold and the fifth threshold increment. The value range of the fifth threshold increment can be 1Mbps-10Mbps, for example, 1Mbps or 5Mbps.

[0194] The seventh RSSI threshold may be the sum of the fourth RSSI threshold and the sixth threshold increment. The sixth threshold increment may range from -10 dBm to -1 dBm. For example, the sixth threshold increment may be -10 dBm or -5 dBm. Alternatively, the seventh RSSI threshold may be a fixed value, such as -70 dBm, as long as it is greater than the fourth RSSI threshold.

[0195] If condition I is met, it means that if a STA associated with other gateway devices near the gateway device roams to the gateway device, it will need to transmit high-priority business data or the amount of data transmitted is large, or if the STA associated with other gateway devices near the gateway device roams to the gateway device, it is likely that the STA will roam to the gateway device. In this case, the RF channel that has been closed by the first RF circuit can be opened in advance to prepare for the STA service in advance.

[0196] Optionally, the channel opening condition is pre-set in the gateway device. For example, the channel opening condition can be pre-stored in the gateway device before the gateway device leaves the factory. For another example, the channel opening condition can be generated according to the user operation instruction before the gateway device executes the control method. The configuration device (the gateway device or the management device connected to the gateway device) can output a second configuration interface to receive the user operation instruction. The second configuration interface has multiple second configuration options, each second configuration option is used to indicate one of the aforementioned conditions A to Condition I, and the user operation instruction is used to indicate one or more selected second configuration options. When a second configuration option is selected, it means that the channel opening condition includes the condition indicated by the second configuration option. The set of conditions corresponding to all selected second configuration options is the aforementioned channel opening condition.

[0197] In one possible implementation, when the channel opening conditions are met, all closed RF channels of the first RF circuit can be directly opened. In this case, the maximum data transmission capacity of the first RF circuit can be restored as soon as possible, ensuring the service quality of STAs associated with the operating frequency band of the first RF circuit.

[0198] In another possible implementation, when channel activation conditions are met, a second target number of RF channels to be activated can be determined based on the third operating state information of the gateway device; at least some of the RF channels whose first RF circuits are closed can be activated based on the second target number. Dynamically determining the second target number based on the third operating state information of the gateway device can further improve energy conservation. Optionally, the third operating state information includes at least one parameter, and the parameter type included in the third operating state information can be identical, partially identical, or completely different from the parameter type included in the second operating state information.

[0199] During implementation, the method for determining the second target number is similar to the method for determining the first target number. The number of RF channels corresponding to the reference parameter range to which the at least one reference parameter belongs can be determined as the second target number based on the correspondence between the reference parameter range and the number of RF channels. The type of reference parameter in the correspondence used to determine the second target number can be exactly the same as the type of reference parameter in the correspondence used to determine the first target number, or partially different or completely different. When the second target number is less than the number of RF channels that have been closed by the first RF circuit, the second target number of RF channels can be randomly opened; or, the second target number of RF channels can be opened according to a default order.

[0200] Optionally, the method further includes receiving a configuration instruction indicating whether to allow shutting down at least some of the RF channels of the first RF circuit. This configuration instruction enables or disables the gateway device's ability to shut down some of the RF channels of the RF circuit. Disabling this function prevents the gateway device from frequently performing actions to determine whether channel operation decisions are met, further reducing the gateway device's power consumption. This also prevents a single gateway device from shutting down a RF channel, potentially impacting overall network performance.

[0201] In one possible implementation, the configuration instruction is generated based on total load information of the network in which the gateway device resides (e.g., the aforementioned FTTR network). Total load information includes, but is not limited to, the number of STAs associated with all gateway devices in the network in which the gateway device resides, the traffic volume of the target link of the master device, and the like. For example, when the number of STAs associated with all gateway devices exceeds a total number threshold, or the traffic volume of the target link of the master device exceeds a total traffic volume threshold, the master device generates and sends a configuration instruction to the gateway device (i.e., the slave device) indicating that at least some RF channels of the first RF circuit cannot be shut down.
