Description

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

Technical Field

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

Background

The wireless Access device is also called an Access Point (AP), and is an Access Point for a wireless terminal, such as a mobile phone and a notebook computer, to enter a wired network. The wireless access equipment generally comprises route switching access integrated equipment and pure access point equipment, wherein the integrated equipment is responsible for the access of the wireless terminal androutingAnd the like; the pure access device is only responsible for the access operation of the wireless terminal, and is generally used for expanding the coverage area of the wireless network.

After accessing a network, a 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. The common wireless access equipment is generally used by plugging in a power adapter, and the problem of equipment power consumption is not necessary to be considered at this time, but for the mobile wireless access equipment using a battery, the higher power consumption means the practical problems of reduced cruising ability and the like of a product.

Disclosure of Invention

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

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

the wireless access equipment identifies whether all the STA equipment of the accessed network supports an MU-EDCA mechanism;

if all STA equipment accessed to the network supports an MU-EDCA mechanism, the wireless access equipment controls all STA equipment to suspend sending messages within a preset time through the MU-EDCA mechanism, and the wireless access equipment is switched from a current working mode to a sleep mode.

The MU-EDCA mechanism is a channel access mechanism defined by the Wi-Fi 6 standard, and the wireless access device may control each connected STA device supporting the mechanism to suspend sending a packet within a preset time through the mechanism. During the period, the wireless access equipment enters a sleep mode, and can suspend the sending and receiving work of the message, thereby reducing the power consumption and improving the endurance 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 wireless access equipment acquires an association request frame sent by the target STA equipment;

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

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

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

Further, the controlling, by the wireless access device through an MU-EDCA mechanism, that all the STA devices suspend sending the packet within a preset time may include:

the wireless access equipment sends a first Trigger Frame control Frame to all the STA equipment, wherein the first Trigger Frame control Frame is used for setting Aifsn parameters in MU-EDCA parameter records of all the STA equipment to be 0 so as to control all the STA equipment to suspend executing the idle channel competition 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 device to suspend the execution of the air interface channel contention packet sending operation, and the MU-EDCA Timer is a Timer defined by the EU-EDCA mechanism and used for controlling the STA device to suspend the execution of the air interface channel contention 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 the execution of the contention packet sending operation of the air interface channel, and the MU-EDCA Timer is a Timer for controlling the time for controlling the STA device to suspend the execution of the contention packet sending operation of the air interface channel. Therefore, the wireless access equipment can set the Aifsn parameters in the MU-EDCA parameter records of all the STA equipment to 0 by sending the Trigger Frame control Frame to all the STA equipment, thereby realizing the purpose of controlling all the STA equipment to suspend sending the message within the timing time of the MU-EDCA Timer.

After the wireless access device switches from the current operating 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 is accessed into the network, switching the sleep mode back to the working mode, and controlling all the STA equipment to recover sending the message through the MU-EDCA mechanism.

After the wireless access device enters the sleep mode, if it is detected that one or more STA devices not supporting the MU-EDCA mechanism access the network, at this time, since the wireless access device cannot control the newly accessed STA device to suspend sending the packet through the MU-EDCA mechanism, in order to receive the packet sent by the newly accessed STA device, the wireless access device must immediately switch back to the working mode, and control all the other STA devices supporting the MU-EDCA mechanism to resume sending the packet through the MU-EDCA mechanism.

Further, the controlling, by the radio access device, the all STA devices to resume sending the packet 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 timers of all the STA equipment to be 0 so as to control all the STA equipment to resume performing the contention packet sending operation of an air interface channel.

Before, 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 is not reached, the wireless access device may set the timing time of the MU-EDCA Timer timers of all the STA devices to 0 by sending a Trigger Frame control Frame, which may immediately end the timing and control all the STA devices to resume sending the message.

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

if all STA equipment accessed to the network supports an MU-EDCA mechanism and each STA equipment in all the STA equipment does not execute the preset type of service operation currently, the wireless access equipment controls all STA equipment to suspend sending messages within the preset time through the MU-EDCA mechanism, and the wireless access equipment is switched from the current working mode to the dormant mode.

If a certain STA device having access to a network is performing certain predetermined types of service operations, such as live video, electronic sports games, etc., which require high network delay, if the wireless access device enters a sleep mode, the STA device may be adversely affected in normal operation, which may cause network congestion and even disconnection. Therefore, the wireless access device enters the sleep mode only when all STA devices accessing the network support the MU-EDCA mechanism and all STA devices do not currently perform the predetermined type of traffic operation. Through the arrangement, the requirements of each STA device on time delay can be considered, the balance of different service type performances and device power consumption is met, and the user experience is ensured.

Specifically, whether any target STA device in all the STA devices currently executes the predetermined type of service operation may be detected in the following manner:

the wireless access equipment acquires a data packet currently sent by the target STA equipment;

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

When detecting whether a certain STA device executes the predetermined type of service operation currently, the wireless access device may obtain a data packet currently sent by the STA device, and analyze a packet header of the data packet to obtain an analysis result, where the analysis 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 with a higher requirement on network delay, and if the service type is met, it may be determined that the STA device is currently executing the service operation of the predetermined type.

if all STA equipment accessed to the network supports an MU-EDCA mechanism and the current data flow sum of all STA equipment is smaller than a preset threshold value, the wireless access equipment controls all STA equipment to suspend sending messages within a preset time through the MU-EDCA mechanism, and the wireless access equipment is switched from a current working mode to a sleep mode.

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

if all STA equipment accessed to a network supports an MU-EDCA mechanism, each STA equipment in all STA equipment does not execute preset type service operation at present, and the current data flow sum of all STA equipment is smaller than a preset threshold value, the wireless access equipment controls all STA equipment to suspend sending messages within preset time through the MU-EDCA mechanism, and the wireless access equipment is switched to a dormant mode from a current working mode.

In another embodiment, multiple factors may be considered at the same time, and the wireless access device may be switched to the sleep mode only when all the STA devices support the MU-EDCA mechanism, and each STA device in all the STA devices does not currently execute the predetermined type of service operation, and the current data traffic sum of all the STA devices is smaller than the preset threshold value, so that balance among system power consumption, service operation performance executed by each STA device, and network performance of the system can be considered.

Further, after the wireless access device switches from the current operating mode to the sleep mode, the method may further include:

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

After the wireless access device is switched to the sleep mode, the wireless access device can suspend the sending and receiving work of the messages, cache the messages to be sent to each STA device, and continue to send the messages after the wireless access device is switched back to the work mode subsequently.

and after the preset time is reached, the wireless access equipment is switched back to the working mode from the sleep mode, sends the cached message to the corresponding STA equipment, and then returns to execute the step of identifying whether all the STA equipment of the accessed network supports the MU-EDCA mechanism.

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 cached message can be sent to the corresponding STA device, and then the step of identifying whether all the STA devices of all the sites accessed to the network support the MU-EDCA mechanism is returned, that is, the next dormancy control process is entered, and the process is repeated.

In a second aspect, an embodiment of the present application provides a control apparatus for 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 the STA equipment of the accessed network support an MU-EDCA mechanism;

and the dormancy control module is used for controlling all the STA equipment to suspend sending the message within the preset time through the MU-EDCA mechanism if all the STA equipment accessed to the network supports the MU-EDCA mechanism, and the wireless access equipment is switched 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 executable on the processor, where when the processor executes the computer program, the wireless access device implements the method for controlling a wireless access device as set forth in the first aspect of the embodiment of the present application.

In a fourth aspect, an embodiment of the present application provides a computer-readable storage medium, where a computer program is stored, and the computer program, when executed, implements the method for controlling a wireless access device as set forth in the first aspect of the embodiment of the present application.

In a fifth aspect, the present application provides a computer program product, which when running on a terminal device, causes the terminal device to execute the method for controlling a wireless access device as set forth in the first aspect of the present application.

The technical effects that can be achieved by the second aspect to the fifth aspect may refer to the technical effects described in the first aspect, and are not described herein again.

As to the details of the implementation of this control method, reference may be made to the various method embodiments described below.

Fig. 2 is a schematic diagram illustrating a hardware structure of a wireless access device according to an embodiment of the present disclosure. Referring to fig. 2, the wireless access apparatus includes: a Radio Frequency (RF) circuit 110, a memory 120, an input unit 130, a display unit 140, a wireless fidelity (WiFi) module 150, a processor 160, and a power supply 170. Those skilled in the art will appreciate that the configuration shown in fig. 2 does not constitute a limitation of the wireless access device and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

The following describes each component 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 then process the information to the processor 160; in addition, the information issued by the design is sent to each STA device. Typically, the RF circuitry includes, but is not limited to, an antenna, at least one Amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like.

The memory 120 may be used to store software programs and modules, and the processor 160 executes various functional applications and data processing of the wireless access device by operating 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 generate key signal inputs related to user settings and function control of the wireless access device. Specifically, 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 the 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 (LCD), an Organic Light-Emitting Diode (OLED), or the like.

It will be appreciated that the modem processor described above may not be integrated into processor 160.

The wireless access device also includes a power source 170 (e.g., a battery) for powering the various components, which may preferably be logically coupled to the processor 160 via a power management device to manage charging, discharging, and power consumption management functions via the power management device.

With the popularization of the Wi-Fi 6 protocol, a large number of Wi-Fi 6 devices are pushed out, and the power consumption is increased while the performance is improved. Especially for the following Wifi devices, such as mobile AP routers powered by batteries, the power consumption problem faced is more severe. Unlike devices such as cell phones and tablet computers as STAs, the Wi-Fi 6 protocol itself has low power consumption for STAs, while there is substantially no low power consumption for devices such as APs. For mobile AP equipment with a battery, the power consumption directly influences the endurance experience of the product and is 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 products.

Fig. 3 shows a flowchart of a method for controlling a wireless access device according to an embodiment of the present application, where the method includes:

301. the wireless access equipment identifies whether all the STA equipment of the accessed network supports 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, the wireless access device is used as an access point for each STA device to enter a network, and the accessed STA device may be a mobile phone, a tablet computer, a wearable device, an in-vehicle device, an Augmented Reality (AR)/Virtual Reality (VR) device, a notebook computer, a super-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), a large-screen television, and other various types of terminal devices. It should be noted that the control method is applicable to a wireless access device accessing 1 or more STA devices of any number, and the specific number of the STA devices accessing the network is not limited in the present application.

When the wireless access equipment works, whether all station STA equipment which accesses the network through the wireless access equipment supports the MU-EDCA mechanism or not can be identified. The MU-EDCA mechanism is a Channel Access mechanism for controlling a high-efficiency station device HE-STA to Access a network by a high-efficiency wireless Access device HE-AP defined by a Wi-Fi 6 standard, wherein an MU prefix represents multiple users, and EDCA is Enhanced Distributed Channel Access. The channel access mechanism defines an operation flow of each STA device for air interface channel competition packet sending, and is a basic mechanism for realizing interaction between the STA device and the wireless access device. For a detailed description of the MU-EDCA mechanism, the definition in the Wi-Fi 6 standard can be referred to and will not be described herein.

When a certain STA equipment accesses the network, the wireless access equipment can identify whether the STA equipment supports the MU-EDCA mechanism or not through the association handshake process of the STA equipment, and records the result of whether the STA equipment supports the MU-EDCA mechanism or not.

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

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

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

(3) and if the association request frame does not carry the HE information field, the wireless access equipment determines that the target STA equipment does not support an MU-EDCA mechanism.

An Association Request frame (Association Request) is a management frame initiated by the STA device and used for establishing a negotiation of a wireless link service between the STA device and the wireless 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 an STA device supporting an MU-EDCA mechanism, an association request frame sent by the STA device necessarily carries an HE information field defined by the Wi-Fi 6 standard, and therefore, whether the STA device supports the MU-EDCA mechanism can be determined by detecting whether the association request frame sent by the STA device carries the 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 among all the STA devices accessing the network does not support the MU-EDCA mechanism, step 303 is executed.

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

all STA equipment accessed to the network supports an MU-EDCA mechanism, and the wireless access equipment can control all STA equipment to suspend sending messages within preset time through the MU-EDCA mechanism. After all the STA devices suspend sending messages, the wireless access device can be switched from the current working mode to the sleep mode (low power consumption mode), so that the power consumption is reduced. Through the MU-EDCA mechanism, the wireless access device may schedule each STA device (provided that the STA devices support the MU-EDCA mechanism) that has accessed the network, and control the uplink packet sending time of the STA device. In order to ensure the power consumption reduction effect, the preset time may be set to be longer without affecting the STA service operation, for example, may be set to 1 second. After all STA equipment is controlled to suspend sending messages within the preset time, the wireless access equipment does not need to execute sending and receiving work of the messages within the time, the current work mode can be switched to a low-power-consumption sleep mode, the Wifi function is stopped, and a radio frequency channel is closed 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 message sending and receiving work.

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

In a wireless network system, in addition to a 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 the wireless access device enters 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 and DDR frequency modulation 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, the wireless access device sends a wake-up command to the network devices, so that the network devices recover to the normal working mode.

Specifically, the controlling, by the radio access device through the MU-EDCA mechanism, that all the STA devices suspend sending the packet within the preset time may include:

the wireless access equipment sends a first Trigger Frame control Frame to all the STA equipment, wherein the first Trigger Frame control Frame is used for setting Aifsn parameters in MU-EDCA parameter records of all the STA equipment to be 0 so as to control all the STA equipment to suspend executing the idle channel competition packet sending operation within the timing time of an MU-EDCA Timer.

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

TABLE 1

Table 1 lists the 8 parameter fields of the MU-EDCA parameter, with the number below each parameter field indicating the length of the field, in octets, and 1 Octet indicating 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 competition Parameter definitions. For each MU AC Parameter Record field, the structure 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, and the numbers below these parameters indicate the length of the field, in terms of Octet, and 1 Octet indicates 8 bits. When Aifsn is set to be 0, the corresponding STA device may be controlled to suspend performing the contention packet sending operation of the air interface channel within a certain Time (the timing Time of the MU-EDCA Time), that is, to suspend sending the packet. There are 4 MU AC Parameter Record fields, which are defined for different contention parameters, and all the Aifsn parameters in the 4 MU AC Parameter Record fields need to be set to 0 during operation, and corresponding 4 MU-EDCA Timer timers may be set at the same time, and the timers may be set in units of 8TU (1TU 1024us), and may be generally set to a millisecond level. The wireless access device may set the MU-EDCA parameter of each STA device by sending a Trigger Frame control Frame, for example, setting Aifsn therein to 0 or 1, starting or resetting a MU-EDCA Time timer, and the like.

After the wireless access device enters the sleep mode, if it is detected that one or more STA devices not supporting the MU-EDCA mechanism access the network, at this time, since the wireless access device cannot control the newly accessed STA device to suspend sending the packet through the MU-EDCA mechanism, in order to receive the packet sent by the newly accessed STA device, the wireless access device must immediately switch back to the working mode (no matter whether the preset time is reached), and control all the remaining STA devices supporting the MU-EDCA mechanism to immediately resume sending the packet through the MU-EDCA mechanism.

Specifically, the controlling, by the radio access device through the MU-EDCA mechanism, that all the STA devices resume sending the packet may include:

303. The wireless access device maintains a current operating mode.

At least one STA device in all STA devices accessed to the network does not support an MU-EDCA mechanism, and as the wireless access device cannot control the STA device which does not support the MU-EDCA mechanism to suspend sending the message through the MU-EDCA mechanism, the wireless access device needs to be kept in a working mode in order to receive the message sent by the STA device which does not support the MU-EDCA mechanism.

According to the method and the device, whether all the STA equipment of the station accessed to the network supports the MU-EDCA mechanism or not is identified, and if the STA equipment of the station accessed to the network supports the MU-EDCA mechanism, the wireless access equipment can control all the STA equipment to suspend sending the message within the preset time through the MU-EDCA mechanism. During the period, the wireless access equipment enters a sleep mode, and can suspend the sending and receiving work of the message, thereby reducing the power consumption and improving the endurance of the product.

Fig. 4 is a flowchart illustrating a control method for a wireless access device according to another embodiment of the present application, where the control method includes:

401. the wireless access equipment identifies whether all the STA equipment of the accessed network supports an MU-EDCA mechanism;

for a detailed description of step 401, reference may be made to step 301. If all the STA equipment accessed to the network supports the MU-EDCA mechanism, executing step 402; if at least one STA device among all the STA devices accessing the network does not support the MU-EDCA mechanism, step 404 is executed.

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

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

(1) the wireless access equipment acquires a data packet currently sent by the target STA equipment;

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

When detecting whether a certain STA device executes the predetermined type of service operation currently, the wireless access device may obtain a data packet currently sent by the STA device, and analyze a packet header of the data packet to obtain an analysis result, where the analysis 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 with a higher requirement on network delay, and if the service type is met, it may be determined that the STA device is currently executing the service operation of the predetermined type. The process may also be referred to as SA (service aware) service type identification, which simply means analyzing a data packet header, matching the analyzed features with a pre-constructed SA feature library to identify a specific service type, and further determining whether the identified service type belongs to a service type with a high requirement on network delay, such as live video, games, and the like.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

For ease of 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 an actual scenario.

In fig. 8, the 2 STA devices under the AP, which are the wireless access device AP, are STA1 and STA2, respectively, and STA1 and STA2 both support the MU-EDCA mechanism.

The functional modules of the AP are shown in fig. 9, and include a dormancy control module, an SA service identification module, a traffic monitoring module, a user access management module, and a Wifi module. The function of each module is shown in table 3 below:

TABLE 3

The working flow of the wireless access device AP is shown in fig. 10:

firstly, a user access management module identifies whether the STA1 and the STA2 both support an MU-EDCA mechanism; if both support the MU-EDCA mechanism, the SA service identification module detects whether the STA1 and the STA2 are currently performing some specified service operations (such as live video, network games, etc.) with high requirements on latency; if neither STA1 nor STA2 performs the designated service operation, the traffic monitoring module detects the sum of real-time data traffic of STA1 and STA 2; if the sum of the real-time data flow does not exceed the threshold value, the AP controls the STA1 and the STA2 to suspend message sending in a Trigger Frame control Frame sending mode; in the timing time of the MU-EDCA Timer, the AP enters a sleep mode and stops the receiving and sending work of the message; after the MU-EDCA Timer expires, the AP wakes up, returns to the working mode, the STA1 and the STA2 recover to send the messages, the AP receives the messages sent by the STA1 and the STA2, and can correspondingly send the cached messages to the STA1 and the STA 2.

If STA1 or STA2 does not support the 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 will remain in the working mode, and may close the MU-EDCA mechanism for controlling STA packet sending by sending Trigger Frame control Frame.

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

Fig. 8 is a schematic diagram of message interaction between a wireless access device and an STA device, as shown in fig. 11. In fig. 11, the AP is first in working (work) mode, and both STA1 and STA2 are sending message data (data) to the AP; if the AP detects that the current logic for performing sleep control is satisfied (i.e., both STA1 and STA2 support the MU-EDCA mechanism, neither execute the specified service operation, and the sum of the real-time data traffic does not exceed the threshold value T), the AP may send a Trigger Frame control Frame, so that STA1 and STA2 suspend sending packets within the timing time of the MU-EDCA Timer, and the AP enters a sleep mode during this time; when the period t (i.e. the timing time) of the MU-EDCA Timer reaches, the AP returns to the working mode, the STA1 and the STA2 resume sending messages, wait for entering the next sleep control period, and so on.

The traditional Wifi packet sending logic is actively triggered by the STA equipment, and the AP cannot control the packet sending time of the STA equipment, so that the AP must be in a working state all the time, and the power consumption is large. Aiming at the problem, the AP active scheduling idea is adopted, the packet sending time of the STA equipment is controlled through the MU-EDCA, the AP enters the sleep mode in the period of time when the STA equipment does not send the packet, and the power consumption is reduced. Meanwhile, the method and the device consider the requirements of different service operations on network delay and the requirements of each STA device on network speed and other performances, and balance among system power consumption, service operation performance executed by each STA device and network performance of the system can be achieved.
