Description

Control method and device of wireless access equipment and wireless access equipment

Technical Field

The present application belongs to the field of network communication technologies, and in particular, relates to a method and an apparatus for controlling a wireless access device, and a computer readable storage medium.

Background

A wireless Access device is also called as an Access Point (AP), and is an Access Point for a wireless terminal such as a mobile phone or a notebook computer to enter a wired network. The wireless access device generally comprises a route switching access integrated device and a pure access point device, wherein the integrated device is responsible for the access of the wireless terminal and the pure access point device RoutingWaiting for work; whereas pure access devices are only responsible for the access operation of wireless terminals, typically for expanding the coverage of wireless networks.

After accessing the network, the wireless terminal becomes a Station (STA) device in the network. The wireless access device generally needs to keep working all the time to ensure that the messages sent by each STA device can be received at any time, which results in higher power consumption of the wireless access device. A common wireless access device is generally used by plugging in a power adapter, and the problem of power consumption of the device is not needed to be considered at this time, but for a mobile wireless access device using a battery, a higher power consumption means a practical problem of reduced product cruising ability and the like.

Disclosure of Invention

In view of this, the embodiments of the present application provide a method, an apparatus, a terminal device, and a computer readable storage medium for controlling a wireless access device, which can reduce power consumption of the wireless access device and improve product endurance.

In a first aspect, an embodiment of the present application provides a method for controlling a wireless access device, including:

the wireless access device identifies whether all station STA devices accessed to the network support an MU-EDCA mechanism;

if all the STA devices accessed to the network support the MU-EDCA mechanism, the wireless access device controls all the STA devices to pause sending messages within a preset time through the MU-EDCA mechanism, and the wireless access device is switched from the current working mode to the dormant mode.

The MU-EDCA mechanism is a channel access mechanism defined by the Wi-Fi 6 standard, through which a wireless access device can control each STA device that is connected and supports the mechanism to suspend sending a message for a preset time. In the period, the wireless access equipment enters the sleep mode, and can suspend the sending and receiving work of the message, thereby reducing the power consumption and improving the cruising ability of the product.

Further, whether any one target STA device of the all STA devices supports the MU-EDCA mechanism may be identified by the following manner:

the wireless access device acquires an association request frame sent by the target STA device;

if the association request frame carries an HE information field defined by Wi-Fi 6 standard, the wireless access device determines that the target STA device supports an MU-EDCA mechanism;

and if the HE information field is not carried in the association request frame, the wireless access device determines that the target STA device does not support an MU-EDCA mechanism.

For the STA device supporting the MU-EDCA mechanism, the association request frame sent by the STA device must carry the HE information field defined by the Wi-Fi 6 standard. Therefore, whether the STA device supports the MU-EDCA mechanism may be determined by detecting whether the association request frame sent by the STA device carries the information field.

Further, the wireless access device controlling, by using the MU-EDCA mechanism, the all STA devices to suspend sending the message within a preset time may include:

the wireless access device sends a first Trigger Frame control Frame to all the STA devices, wherein the first Trigger Frame control Frame is used for setting an Aifsn parameter in MU-EDCA parameter records of all the STA devices to 0 so as to control all the STA devices to pause executing air channel contention for packet sending operation within the timing time of an MU-EDCA Timer;

the timing time is the same as the preset time, the Aifsn parameter is a parameter defined by an EU-EDCA mechanism and used for controlling the STA equipment to pause executing the air channel contention for packet sending operation, and the MU-EDCA Timer is a Timer defined by the EU-EDCA mechanism and used for controlling the STA equipment to pause executing the air channel contention for packet sending operation.

In the MU-EDCA parameter record of the STA device, the Aifsn parameter is a parameter for controlling the STA device to suspend performing the air-channel contention packet transmission operation, and the MU-EDCA Timer is a Timer for controlling the time for controlling the STA device to suspend performing the air-channel contention packet transmission operation. Therefore, the wireless access device can set the Aifsn parameter in the MU-EDCA parameter record of all the STA devices to 0 by sending the Trigger Frame control Frame to all the STA devices, thereby achieving the purpose of controlling all the STA devices to pause sending messages within the timing time of the MU-EDCA Timer.

After the wireless access device is switched from the current operation mode to the sleep mode, the method may further include:

and if the wireless access equipment detects that at least one STA equipment which does not support the MU-EDCA mechanism accesses the network, switching back to the working mode from the dormant mode, and controlling all the STA equipment to resume sending the message through the MU-EDCA mechanism.

After the wireless access device enters the sleep mode, if one or more than one STA device which does not support the MU-EDCA mechanism is detected to access the network, at this time, the wireless access device cannot control the newly accessed STA device to pause sending the message through the MU-EDCA mechanism, in order to receive the message sent by the newly accessed STA device, the wireless access device must immediately switch back to the working mode, and control all the rest of the STA devices which support the MU-EDCA mechanism to resume sending the message through the MU-EDCA mechanism.

Further, the controlling, by the wireless access device, the STA devices to resume sending the message through the MU-EDCA mechanism may include:

and the wireless access equipment sends a second Trigger Frame control Frame to all the STA equipment, wherein the second Trigger Frame control Frame is used for setting the timing time of the MU-EDCA Timer of all the STA equipment to be 0 so as to control all the STA equipment to resume performing the air channel contention packet sending operation.

Previously, the wireless access device has controlled all STA devices to suspend sending messages within the timing time of the MU-EDCA Timer. Before the timing time does not arrive, the wireless access device may set the timing time of the MU-EDCA Timer of all STA devices to 0 by sending a Trigger Frame control Frame, that is, immediately end the timing, and control all STA devices to resume sending the message.

Further, if all STA devices that have access to the network support the MU-EDCA mechanism, the wireless access device controls, through the MU-EDCA mechanism, the all STA devices to suspend sending a message within a preset time, and the wireless access device switches from the current working mode to the sleep mode, which may include:

if all the STA devices accessed to the network support the MU-EDCA mechanism and each STA device in all the STA devices does not currently execute the preset type of service operation, the wireless access device controls all the STA devices to pause sending messages within the preset time through the MU-EDCA mechanism, and the wireless access device is switched to the sleep mode from the current working mode.

If a certain STA device that has been connected to the network is executing certain predetermined types of service operations, such as live video broadcast, electronic game, etc., with high requirements for network delay, at this time, if the wireless access device enters the sleep mode, adverse effects will be brought to the normal operation of the STA device, resulting in problems such as network blocking and even disconnection. Thus, the wireless access device will enter sleep mode only if all STA devices accessing the network support the MU-EDCA mechanism and none of the STA devices currently performs the predetermined type of traffic operation. By the arrangement, the requirement of each STA device on time delay can be considered, the balance of the performances of different service types and the power consumption of the device can be met, and the user experience is ensured.

Specifically, whether any one of the target STA devices currently performs the predetermined type of service operation may be detected by:

the wireless access device acquires a data packet currently transmitted by the target STA device;

and the wireless access equipment analyzes the packet header of the data packet and determines whether the target STA equipment currently executes the service operation of the preset type according to the analysis result.

When detecting whether a certain STA device currently executes the predetermined type of service operation, the wireless access device may acquire a data packet currently transmitted by the STA device, parse a packet header of the data packet to obtain a parsing result, where the parsing result may include information such as a service type currently executed by the STA device. Then, the service type may be compared with a preset service type having a higher requirement for network delay, and if the service type is met, it may be determined that the STA device is currently performing the preset service operation.

If all the STA devices accessed to the network support the MU-EDCA mechanism and the current data flow sum of all the STA devices is smaller than a preset threshold value, the wireless access device controls all the STA devices to pause sending messages within a preset time through the MU-EDCA mechanism, and the wireless access device is switched to a sleep mode from a current working mode.

In order to reduce power consumption, the wireless access device needs to switch to sleep mode, but this necessarily affects the network performance of the system. Therefore, considering the balance of system power consumption and performance, the current data flow sum of all the STA devices accessed to the network can be detected, and if the data flow sum is smaller than a preset threshold value, the current performance requirements of each STA device on the network such as the speed and the like are lower, and the wireless access device can enter a sleep mode; if the sum of the data flows is greater than or equal to the threshold value, it indicates that the performance requirements of each STA device on the network rate and the like are higher, and the wireless access device must be kept in the working mode.

If all the STA devices accessed to the network support the MU-EDCA mechanism, each STA device in all the STA devices does not currently execute the preset type of service operation, and the current data flow sum of all the STA devices is smaller than a preset threshold value, the wireless access device controls all the STA devices to pause sending messages within the preset time through the MU-EDCA mechanism, and the wireless access device is switched to the sleep mode from the current working mode.

In another embodiment, a plurality of factors may be considered simultaneously, and the wireless access device may switch to the sleep mode only when all STA devices support the MU-EDCA mechanism and each STA device in all STA devices does not currently perform a predetermined type of service operation and the sum of current data traffic of all STA devices is less than a preset threshold, so that balance among system power consumption, service operation performance performed by each STA device, and network performance of the system may be considered.

Further, after the wireless access device is switched from the current operation mode to the sleep mode, the method may further include:

and the wireless access equipment caches the messages to be sent to each STA equipment.

After the wireless access device is switched to the sleep mode, the sending and receiving operation of the messages can be suspended, the messages to be sent to each STA device are cached, and the messages are continuously sent after the subsequent switching back to the working mode.

Still further, after the wireless access device is switched from the current operation mode to the sleep mode, the method may further include:

and after the preset time is reached, the wireless access equipment is switched back to the working mode from the dormant mode, the cached message is sent to the corresponding STA equipment, and then the step of executing the step of identifying whether all the station STA equipment of the accessed network support the MU-EDCA mechanism is executed.

After the preset time is reached, each STA device resumes sending the message, the wireless access device switches back to the working mode, resumes sending and receiving the message, at this time, the previously buffered message may be sent to the corresponding STA device, and then returns to execute the step of identifying whether all STA devices of the stations that have access to the network support the MU-EDCA mechanism, that is, enters the next sleep control process, and circulates in this way.

In a second aspect, an embodiment of the present application provides a control apparatus of a wireless access device, including:

The system comprises an MU-EDCA mechanism identification module, a network access module and a network access module, wherein the MU-EDCA mechanism identification module is used for identifying whether all station STA equipment accessed to the network support an MU-EDCA mechanism;

and the dormancy control module is used for controlling all the STA devices to pause sending messages within preset time through the MU-EDCA mechanism if all the STA devices accessed to the network support the MU-EDCA mechanism, and switching the wireless access device from the current working mode to the dormancy mode.

In a third aspect, an embodiment of the present application provides a wireless access device, including a memory, a processor, and a computer program stored in the memory and capable of running on the processor, where the wireless access device implements a control method of the wireless access device as set forth in the first aspect of the embodiment of the present application when the processor executes the computer program.

In a fourth aspect, embodiments of the present application provide a computer readable storage medium storing a computer program, where the computer program is executed to implement a method for controlling a wireless access device according to the first aspect of the embodiments of the present application.

In a fifth aspect, embodiments of the present application provide a computer program product, which when run on a terminal device, causes the terminal device to perform a method of controlling a radio access device as set forth in the first aspect of the embodiments of the present application.

Fig. 2 is a schematic diagram of a hardware structure of a wireless access device according to an embodiment of the present application. Referring to fig. 2, the wireless access device includes: radio Frequency (RF) circuitry 110, memory 120, input unit 130, display unit 140, wireless fidelity (wireless fidelity, wiFi) module 150, processor 160, and power supply 170. Those skilled in the art will appreciate that the structure shown in fig. 2 is not limiting of the wireless access device and may include more or fewer components than shown, or may combine certain components, or a different arrangement of components.

The following describes the components of the wireless access device in detail with reference to fig. 2:

the RF circuit 110 may be configured to receive and transmit information, and in particular, receive information reported by each STA device and process the information with the processor 160; in addition, information issued by the design is sent to each STA device. Typically, RF circuitry includes, but is not limited to, antennas, at least one amplifier, transceivers, couplers, low noise amplifiers (Low Noise Amplifier, LNAs), diplexers, and the like.

The memory 120 may be used to store software programs and modules, and the processor 160 may perform various functional applications and data processing of the wireless access device by executing the software programs and modules stored in the memory 120.

The input unit 130 may be used to receive input numeric or character information and to generate key signal inputs related to user settings and function control of the wireless access device. In particular, the input unit may include, but is not limited to, a physical keyboard, function keys, and the like.

The display unit 140 may be used to display information input by a user or information provided to the user and various menus of the wireless access device. The display unit 140 may include a display panel, and optionally, the display panel may be configured in the form of a liquid crystal display (Liquid Crystal Display, LCD), an Organic Light-Emitting Diode (OLED), or the like.

WiFi belongs to the short-range wireless transmission technology, and wireless access devices provide a network access function for each STA device through the WiFi module 150.

With the popularization of Wi-Fi 6 protocol, wi-Fi 6 equipment is greatly promoted, and the power consumption is increased while the performance is improved. Especially for the accompanying Wifi devices, such as battery-powered mobile AP routers, the power consumption problem faced by them is more severe. Unlike devices such as mobile phones and tablet computers, which are used as STAs, the Wi-Fi 6 protocol has low power consumption consideration for STAs, but basically has no low power consumption consideration for devices used as APs. For mobile AP equipment with a battery, the power consumption directly influences the cruising experience of the product and is also an important index for improving the competitiveness of the product. The control method of the wireless access equipment can reduce the power consumption of the AP equipment and improve the cruising ability of the product.

Fig. 3 shows a flowchart of a control method of a wireless access device according to an embodiment of the present application, including:

301. the wireless access device identifies whether all station STA devices accessed to the network support an MU-EDCA mechanism;

The execution main body of the control method provided by each embodiment of the present application is a wireless access device, where the wireless access device is used as an access point for each STA device to enter a network, and the STA device to be accessed may be a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (augmented reality, AR)/Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (personal digital assistant, PDA), a large-screen television, and other various terminal devices. It should be noted that, the control method is applicable to wireless access devices accessing any number of STA devices above 1, and the present application does not limit the specific number of STA devices accessing the network.

When the wireless access device works, the wireless access device can identify whether all station STA devices accessed to the network through the wireless access device support the MU-EDCA mechanism. The MU-EDCA mechanism is a channel access mechanism defined by Wi-Fi 6 standard, in which a high-efficiency wireless access device HE-AP controls a high-efficiency station device HE-STA to access a network, and the MU prefix represents multiple users, EDCA is Enhanced Distributed Channel Access. The channel access mechanism defines the operation flow of each STA device for carrying out air interface channel competition package, and is a basic mechanism for realizing interaction between the STA device and the wireless access device. The detailed description of the MU-EDCA mechanism may refer to the definition in the Wi-Fi 6 standard, and will not be repeated here.

When a certain STA device accesses a network, the wireless access device can identify whether the STA device supports an MU-EDCA mechanism through an association handshake process of the STA device, and records the result of whether the STA device supports the MU-EDCA mechanism.

Specifically, whether any one target STA device of the all STA devices supports the MU-EDCA mechanism may be identified by the following manner:

(1) The wireless access device acquires an association request frame sent by the target STA device;

(2) If the association request frame carries an HE information field defined by Wi-Fi 6 standard, the wireless access device determines that the target STA device supports an MU-EDCA mechanism;

(3) And if the HE information field is not carried in the association request frame, the wireless access device determines that the target STA device does not support an MU-EDCA mechanism.

The association request frame (Association Request) is a management frame initiated by the STA device for establishing a radio link service negotiation between the STA device and the radio access device. The HE information field is a specific field defined by the Wi-Fi 6 standard, and is used to indicate whether a corresponding STA device is a high efficiency station device (HE-STA), and may be used to determine whether a certain STA device supports the MU-EDCA mechanism. For the STA device supporting the MU-EDCA mechanism, the association request frame sent by the STA device must carry the HE information field defined by the Wi-Fi 6 standard, so it can be determined whether the STA device supports the MU-EDCA mechanism by detecting whether the association request frame sent by the STA device carries the HE information field.

If all the STA devices accessed to the network support the MU-EDCA mechanism, executing step 302; if at least one STA device does not support the MU-EDCA mechanism among all STA devices that have access to the network, step 303 is performed.

302. The wireless access device controls all STA devices to pause sending messages within preset time through an MU-EDCA mechanism, and the wireless access device is switched to a sleep mode from a current working mode;

all STA devices accessed to the network support the MU-EDCA mechanism, and the wireless access device can control all the STA devices to pause sending messages within preset time through the MU-EDCA mechanism. After all STA devices suspend transmitting messages, the wireless access device may switch from the current operation mode to a sleep mode (low power mode), thereby reducing power consumption. Through the MU-EDCA mechanism, the wireless access device can schedule each STA device (provided that the STA devices all support the MU-EDCA mechanism) of the accessed network, and control the uplink packet sending time of the STA device. To ensure the power consumption reduction effect, the preset time may be set to be larger, for example, may be set to 1 second, without affecting the STA service operation. After all STA devices are controlled to pause sending messages within a preset time, the wireless access device does not need to execute the sending and receiving work of the messages within the preset time, can be switched to a sleep mode with low power consumption from a current working mode, stops a Wifi function, and closes a radio frequency channel to reduce power consumption. After the preset time is over, each STA device resumes sending the message, and the wireless access device switches back to the working mode again to resume the sending and receiving operation of the message.

Further, the wireless access device may also send a sleep instruction to other network devices associated with the network after switching from the current operating mode to the sleep mode, so that the other network devices enter the sleep mode.

In the wireless network system, besides the wireless access device and each accessed STA device, there are network devices such as a Modem and a network server, and these network devices include functional modules such as CPU frequency modulation and DDR frequency modulation. After entering the sleep mode, the wireless access device can send a sleep control instruction to other network devices in the network, so that the network devices also enter the sleep mode, and the performance of functional modules such as CPU frequency modulation, DDR frequency modulation and the like is reduced, thereby further reducing the power consumption of the whole wireless network system. After the wireless access device switches back to the working mode, a wake-up instruction is sent to the network devices so as to enable the network devices to restore to the normal working mode.

Specifically, the controlling, by the wireless access device through the MU-EDCA mechanism, the suspension of the sending of the message by all STA devices within a preset time may include:

the wireless access device sends a first Trigger Frame control Frame to all the STA devices, where the first Trigger Frame control Frame is configured to set an Aifsn parameter in MU-EDCA parameter records of all the STA devices to 0, so as to control all the STA devices to suspend execution of an air channel contention packet sending operation within a timing time of an MU-EDCA Timer.

The MU-EDCA parameter fields are shown in Table 1 below:

TABLE 1

Table 1 lists 8 parameter fields of MU-EDCA parameters, the number below each parameter field representing the length of the field, in octets, with 1 Octet representing 8 bits. Wherein, muac_ BE Parameter Record, muac_ BK Parameter Record, muac_ VI Parameter Record and muac_ VO Parameter Record are 4 MU AC Parameter Record fields, belong to different service queues, and have different contention parameter definitions. For each MU AC Parameter Record field, there is a structure as shown in table 2 below:

TABLE 2

ACI/Aifsn	ECWmin/ECWmax	MU-EDCA Timer
			1	1	1

In Table 2, the MU AC Parameter Record field contains 3 parameters, ACI/Aifsn, ECWmin/ECWmax and MU-EDCA Timer, respectively, the numbers below these parameters represent the length of the field, in Octet, and 1 Octet represents 8 bits. When the Aifsn is set to 0, the corresponding STA device can be controlled to pause executing the air interface channel contention packet sending operation, namely, pause sending the message, within a certain Time (the timing Time of the MU-EDCA Time). Here, there are 4 fields MU AC Parameter Record, which are defined for different contention parameters, and the Aifsn parameters in these 4 fields MU AC Parameter Record need to be set to 0 in operation, and the corresponding 4 MU-EDCA Timer timers can be set at the same time, and the timers are in units of 8 TUs (1 tu=1024 us), and can be generally set to be timed to the order of milliseconds. The wireless access device may set MU-EDCA parameters of each STA device by sending Trigger Frame control frames, for example, setting Aifsn therein to 0 or 1, starting or resetting MU-EDCA Time timer, and the like.

After the wireless access device enters the sleep mode, if one or more than one STA device which does not support the MU-EDCA mechanism is detected to access the network, at this time, since the wireless access device cannot control the newly accessed STA device to pause sending a message through the MU-EDCA mechanism, in order to receive the message sent by the newly accessed STA device, the wireless access device must immediately switch back to the working mode (whether reaching the preset time or not), and control all the rest STA devices supporting the MU-EDCA mechanism through the MU-EDCA mechanism to immediately resume sending the message.

Specifically, the controlling, by the wireless access device, the recovery of the retransmission packet by all STA devices through the MU-EDCA mechanism may include:

303. The wireless access device maintains a current mode of operation.

All the STA devices which are accessed into the network have at least one STA device which does not support the MU-EDCA mechanism, and the wireless access device can not control the STA devices which do not support the MU-EDCA mechanism to pause sending the message through the MU-EDCA mechanism, so that the wireless access device needs to be kept in a working mode in order to receive the message sent by the STA devices which do not support the MU-EDCA mechanism.

According to the method and the device, whether all station STA devices of the accessed network support the MU-EDCA mechanism is identified, and if all station STA devices support the MU-EDCA mechanism, the wireless access device can control all the STA devices to pause sending messages within preset time through the MU-EDCA mechanism. In the period, the wireless access equipment enters the sleep mode, and can suspend the sending and receiving work of the message, thereby reducing the power consumption and improving the cruising ability of the product.

Fig. 4 shows a flowchart of another control method of a wireless access device according to an embodiment of the present application, including:

401. the wireless access device identifies whether all station STA devices accessed to the network support an MU-EDCA mechanism;

for a detailed description of step 401, reference may be made to step 301. If all the STA devices that have access to the network support the MU-EDCA mechanism, step 402 is executed; if at least one STA device of all STA devices that have access to the network does not support the MU-EDCA mechanism, step 404 is performed.

402. The wireless access device detects whether each STA device in all the STA devices does not execute a preset type of service operation currently;

all STA devices that have access to the network support the MU-EDCA mechanism, and before performing low power control, the wireless access device needs to detect whether each STA device of all STA devices does not currently perform a predetermined type of service operation. The predetermined type of service operation can be specifically an operation with high requirement on network time delay, such as live video broadcast, electronic competitive game and the like.

(1) The wireless access device acquires a data packet currently transmitted by the target STA device;

(2) And the wireless access equipment analyzes the packet header of the data packet and determines whether the target STA equipment currently executes the service operation of the preset type according to the analysis result.

When detecting whether a certain STA device currently executes the predetermined type of service operation, the wireless access device may acquire a data packet currently transmitted by the STA device, parse a packet header of the data packet to obtain a parsing result, where the parsing result may include information such as a service type currently executed by the STA device. Then, the service type may be compared with a preset service type having a higher requirement for network delay, and if the service type is met, it may be determined that the STA device is currently performing the preset service operation. The process can also be called SA (Service Awareness) service type identification, simply speaking, the data packet header is analyzed, the characteristics obtained by analysis are matched with the pre-constructed SA characteristic library, the specific service type is identified, and then whether the identified service type belongs to the service type with high requirement on network delay, such as video live broadcast, games and the like is judged.

If each STA device of the all STA devices does not currently perform the predetermined type of service operation, step 403 is performed; if at least one STA device of the all STA devices is currently performing a predetermined type of service operation, step 404 is performed.

Step 302 may be referred to as to how the wireless access device controls the STA device to suspend sending the content of the message through the MU-EDCA mechanism.

At least one STA device of all STA devices having access to the network does not support the MU-EDCA mechanism, or at least one STA device of all STA devices is currently performing a predetermined type of service operation, in which case the wireless access device needs to remain in an operation mode in order to receive a message transmitted by the STA device that does not support the MU-EDCA mechanism, or in order to provide stable network performance to the STA device that is performing the predetermined type of service operation.

The method comprises the steps of identifying whether all station STA devices accessed to a network support an MU-EDCA mechanism and detecting whether each STA device in all the STA devices does not execute a preset type of service operation currently; if all the STA devices accessed to the network support the MU-EDCA mechanism and each STA device in all the STA devices does not currently execute the preset type of service operation, the wireless access device can control all the STA devices to pause sending messages within the preset time through the MU-EDCA mechanism and enter a sleep mode.

It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not limit the implementation process of the embodiment of the present application in any way.

For easy understanding, the control method of the wireless access device proposed in the present application is described below in a practical application scenario.

Fig. 8 is a schematic diagram of an application of the control method of the wireless access device in the actual scenario.

In fig. 8, 2 STA devices hung under the AP are STA1 and STA2, respectively, and both STA1 and STA2 support MU-EDCA mechanisms.

The functional modules of the wireless access device AP are shown in fig. 9, and include a sleep control module, an SA service identification module, a traffic monitoring module, a user access management module, and a Wifi module. The functions of the respective modules are shown in the following table 3:

TABLE 3 Table 3

The workflow of the wireless access device AP is as shown in fig. 10:

firstly, a user access management module identifies whether the STA1 and the STA2 support an MU-EDCA mechanism; if the MU-EDCA mechanism is supported, the SA service identification module detects whether the STA1 and the STA2 are currently executing certain specified service operations (such as video live broadcast, network game and the like) with higher time setting requirements; if the designated service operation is not executed by both the STA1 and the STA2, detecting the sum of the real-time data traffic of the STA1 and the STA2 by a traffic monitoring module; if the sum of the real-time data flows does not exceed the threshold value, the AP controls the STA1 and the STA2 to pause sending the message by sending a Trigger Frame control Frame; in the timing time of the MU-EDCA Timer, the AP enters a sleep mode and pauses the receiving and transmitting work of the message; after the MU-EDCA Timer expires, the AP wakes up, returns to the working mode, and the STA1 and the STA2 resume sending messages, and the AP receives the messages sent by the STA1 and the STA2 and can correspondingly send the buffered messages to the STA1 and the STA2.

If STA1 or STA2 does not support MU-EDCA mechanism, or STA1 or STA2 is currently executing the specified service operation, or the sum of the real-time data traffic of STA1 and STA2 exceeds the threshold T, the AP may remain in the working mode, and may close the MU-EDCA mechanism for controlling STA packet sending by sending a Trigger Frame control Frame.

In addition, in the process of AP dormancy, if a newly accessed device STA3 which does not support MU-EDCA mechanism is detected, the AP wakes up immediately, returns to the working mode, and controls STA1 and STA2 to resume sending messages by sending Trigger Frame control frames.

A schematic diagram of the packet interaction between the wireless access device and the STA device in fig. 8 is shown in fig. 11. In fig. 11, the AP is first in a work mode, and both STA1 and STA2 are transmitting packet data (data) to the AP; if the AP detects that the current logic for executing sleep control is met (i.e., both STA1 and STA2 support MU-EDCA mechanisms, neither of which executes the specified service operation, and the sum of the real-time data traffic does not exceed the threshold T), the AP will send a Trigger Frame control Frame, so that STA1 and STA2 pause sending messages within the timing time of the MU-EDCA Timer, and the AP enters sleep (sleep) mode within this time; when the period t (i.e., the timing time) of the MU-EDCA Timer arrives, the AP returns to the working mode, and STA1 and STA2 resume sending messages, wait to enter the next sleep control period, and so on.

The traditional Wifi package logic is actively triggered by the STA equipment, and the AP cannot control the package time of the STA equipment, so that the AP must be in a working state at all times, and the power consumption is high. Aiming at the problem, the method adopts the thought of AP active scheduling, controls the time of the STA equipment to send the packet through MU-EDCA, and the AP enters the sleep mode in the time of the STA equipment not sending the packet, thereby reducing the power consumption. Meanwhile, the method and the device also consider the requirements of different service operations on network delay and the requirements of each STA device on performances such as network rate and the like, and can realize the balance among system power consumption, service operation performance executed by each STA device and network performance of the system.
