[0023] It should be understood that the specific implementations described herein are only used to explain the present application and are not used to limit the present application.

[0024] In the subsequent description, suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present application and have no specific meaning themselves. Therefore, "module", "component" or "unit" may be used interchangeably.

[0025] Currently, in the S1G IoT scenario, the energy management technology on the AP side is similar to that on the station (STA) side, which performs periodic wake-up and sleep in units of beacon intervals. The above periodic wake-up and sleep are implemented by the target wake-up time (TWT). After the STA completes the negotiation with the AP, the STA wakes up periodically and communicates with the AP during the specified service period. Outside the service period, the STA is in sleep mode. In addition, the Individual TWT technology is introduced in IEEE802.11ax, see Figure 1 , AP broadcast announcement is applicable to the periodic energy-saving mechanism of STA. STA joins the energy-saving group through unicast management frames to wake up during a specific service period and guide multi-user transmission by AP. It sleeps outside the service period to reduce power consumption. The IEEE 802.11v standard introduces Base Station Subsystem Transition Management (BTM) technology to enhance the switching capability between different BBSs. Among them, AP and STA complete STA roaming operations through the exchange of BTM query, request, and response management frames. Especially for STAs that support BTM function, AP can also control STA to disconnect from the current AP through BTM request messages. The MLO technology introduced in the IEEE802.11be standard proposes Multi-link Reconfiguration technology, which can realize the addition and deletion of AP-side links and the addition and deletion of non-APMLD associated links. Currently, fiber to the room (FTTR) technology connects wireless router APs in different rooms or locations in scenarios such as homes or small and medium-sized enterprises through optical fibers, thereby providing high-bandwidth and high-reliability connections between multiple APs. The connection between the master control AP and the slave AP can be achieved using a point-to-multipoint optical distribution network.

[0026] Figure 2 is a flow chart of a device energy saving method provided in an embodiment of the present application. The embodiment of the present application can be applied to the case where an access point device saves energy. The method can be executed by a device energy saving device. The device can be implemented by software and / or hardware and is generally integrated in the access point device. Figure 2 The method provided in the embodiment of the present application specifically includes the following steps:

[0027] Step 110: Announce access point energy saving information.

[0028] In the embodiment of the present application, the access point device may announce access point energy saving information to other nodes, and the access point energy saving information may include relevant parameters for energy saving of the current access point device.

[0029] Step 120: Perform energy saving according to the access point energy saving information.

[0030] In an embodiment of the present application, the current access point device can save energy according to the access point energy saving information. For example, it can work according to the access point wake-up duration in the access point energy saving information, or it can wake up according to the next wake-up time point in the access point energy saving information.

[0031] Step 130: Exit the energy saving function.

[0032] In the embodiment of the present application, the current access point device may also exit the energy saving function according to business requirements or high-level instructions.

[0033] In the embodiment of the present application, energy saving of the access point device is achieved by announcing access point energy saving information and performing energy saving according to the access point energy saving information until the energy saving function is exited, thereby reducing the energy consumption of the access point during wireless communication.

[0034] In some application embodiments, performing energy saving according to the access point energy saving information includes: enabling an energy saving function according to an enabling time point of the access point energy saving information.

[0035] The enabling time point may be the time point at which the access point device triggers energy saving, and the access point energy saving information may include parameters such as the enabling time point for triggering the energy saving function and the energy saving cycle used to implement the energy saving function.

[0036] In the embodiment of the present application, the access point device may enable the energy saving function according to the enabling time in the access point energy saving information, so that the current access point device can perform energy saving.

[0037] In some application embodiments, the access point energy saving information is determined according to a periodic traffic pattern of an associated workstation on a current link or a target wake-up time of a broadcast group to which the associated workstation joins.

[0038] Specifically, the access point energy saving information may be determined by the periodic traffic map of the associated workstation on the current link of the current access point device, or the access point energy saving information may be determined by the target wake-up time of the broadcast group joined by the workstation associated with the current access point device.

[0039] In some other application embodiments, the enabling time of the access point energy saving function of the access point energy saving information is determined according to the delivery transmission indication pattern count.

[0040] In an embodiment of the present application, the access point energy saving information includes an enabling time point, which may be a time point that triggers the access point device to perform an energy saving function. The enabling time point may be determined by a delivery transmission indication graph count, wherein the delivery transmission indication graph count may be a field in a Beacon frame, and the length of the field may be one byte, representing the number of Beacon frames to be sent before the next delivery transmission indication graph frame is sent.

[0041] In some other application embodiments, effective link information of access point energy saving information is determined according to links in a multi-link device that use the same access point energy saving information.

[0042] Figure 3 is a flow chart of another device energy saving method provided in an embodiment of the present application. The embodiment of the present application is a specific implementation based on the above-mentioned embodiment of the application. Figure 3 The method provided in the embodiment of the present application specifically includes the following steps:

[0043] Step 210: Announce access point energy saving information via unicast or multicast.

[0044] In the embodiment of the present application, the access point device may announce the access point energy saving information in a multicast or unicast manner.

[0045] Step 220: Enable the energy saving function according to the enabling time point of the access point energy saving information.

[0046] Step 230: Switch to the awake state at a first time point, and exchange frames with the workstation within the awake duration, wherein the first time point includes the access point awakening time point in the access point energy saving information announced by the current access point.

[0047] Among them, the awakening state may be a state in which the access point is working, and in the awakening state the access point may perform frame interaction with an associated workstation; the first time point may be an access point awakening time point in the access point energy saving information announced by the current access point, and the access point may be awakened according to the access point awakening time point, thereby switching from a sleep state to a working state.

[0048] In an embodiment of the present application, when the first time point, that is, the access point wake-up time point, is reached, the access point can wake up and enter the wake-up state. During the wake-up duration, the access point can exchange frames with the workstation, thereby realizing data transmission between the access point and the workstation.

[0049] Step 240: Switch to a sleep state or a non-awakened state at a second time point, wherein the second time point includes at least one of the following: an end time point when the current access point ends frame exchange with the workstation, and an end time point when the current access point wakes up.

[0050] Among them, the second time point can be the end time point when the current access point ends the frame exchange with the workstation, that is, the current access point ends the frame exchange with the workstation when it reaches the second time point, or the second access point can be the end time point of the wake-up duration of the current access point, that is, the current access point ends the wake-up duration when it reaches the second time point, and the current access point can enter a sleep state.

[0051] In the implementation of the present application, the access point device can switch to a sleep state or a non-awakening state when reaching the second time point. In the sleep state or the non-awakening state, the access point device can end the frame exchange with the workstation, or end the wake-up duration.

[0052] Step 250: Exit the energy saving function.

[0053] In some application embodiments, the access point energy saving information includes at least one of the following: the access point next wake-up time point, the access point wake-up duration, the access point wake-up time interval, the link information at which the access point energy saving information takes effect, and the access point energy saving function enabling time point.

[0054] In an embodiment of the present application, the access point energy saving information announced by the access point device may include at least one of the access point next wake-up time point, the access point wake-up duration, the access point wake-up time interval, the link information at which the access point energy saving information takes effect, and the access point energy saving function enabling time point.

[0055] Based on the above application embodiment, it also includes: performing restrictive frame exchange or no frame interaction with the working base station in the sleep state or non-awakening state, wherein the restrictive frame exchange includes an initial control frame and a response frame exchange corresponding to the control frame.

[0056] In an embodiment of the present application, at the second time point, the current access point switches to a sleep state or a non-awakened state. In the sleep state or the non-awakened state, the current access point performs a restrictive frame exchange or does not perform a frame exchange with the workstation. It can be understood that the restrictive frame exchange process includes an initial control frame and a response frame corresponding to the initial control frame.

[0057] In some application embodiments, the workstation does not have an energy-saving function, and before enabling the energy-saving function, the workstation further includes at least one of the following:

[0058] Disconnecting from the workstation; guiding the workstation to perform roaming operation according to the response mode of the basic service set transition management; and guiding link switching through multi-link configuration for non-access point multi-link devices supporting extremely high throughput multi-link operation functions.

[0059] In an embodiment of the present application, when the workstation associated with the current access point does not have an energy-saving function, the current access point may disconnect from the workstation before enabling the energy-saving function, or the current access point guides the workstation to perform a roaming operation according to a response method of the basic service set transition management, or the current access point guides link switching through multi-link configuration for a non-access point multi-link device that supports an extremely high throughput multi-link operation function.

[0060] In some application embodiments, exiting the energy-saving function includes at least one of the following: actively exiting the energy-saving function; exiting the energy-saving function in response to a specific frame interaction of the workstation.

[0061] In the embodiment of the present application, the access point can actively exit the energy-saving function, or the current access point exchanges specific frames with the workstation, so that the current access point exits the energy-saving function.

[0062] In some other application embodiments, the effective link information of the access point energy saving information includes at least one of the following: a link set where the access point energy saving is effective; a link mapping where the access point energy saving is effective; and indicator bit information indicating that different links have the same access point energy saving information when the access point energy saving is effective.

[0063] In an embodiment of the present application, the effective link information included in the access point energy saving information may include a link set where the access point energy saving is effective; a link mapping where the access point energy saving is effective; and at least one of the indication bit information indicating that different links have the same access point energy saving information when the access point energy saving is effective.

[0064] In some application embodiments, the access point energy saving information is the same as the access point energy saving information of at least one other access point, and the access point energy saving information includes link information identifiers corresponding to the other access points.

[0065] In an embodiment of the present application, a multi-link device may include multiple sub-access points, the current access point may be at least one of the sub-access points, there is at least one other sub-access point in the multi-link device that has the same access point energy saving information as the current access point, and the access point energy saving information may include link identification information, and the link identification information identifies other sub-access points in the multi-link device, that is, the access point energy saving information of the current access point may include link identification information corresponding to other sub-access points in the multi-link device.

[0066] In some application embodiments, the energy saving function enabling time corresponding to the access point energy saving information at least satisfies that all workstations receive the access point energy saving information at least once before the access point energy saving function is enabled.

[0067] The function enabling time may be a time period during which the energy-saving function is enabled.

[0068] In the embodiment of the present application, the time period corresponding to the energy-saving function enabling time in the access point energy-saving information can satisfy that before the access point energy-saving function is enabled, all workstations associated with the access point receive the access point energy-saving information once. That is, the access point needs to set the access point energy-saving function enabling time to be large enough to ensure that all workstations can receive the access point energy-saving information announced by the access point at least once before the energy-saving function is enabled. For example, the AP sets the energy-saving function enabling time point after the next delivery transmission indication map beacon (Traffic Indication Map beacon, DTIM beacon) arrives to ensure that each subsequent beacon (including the next DTIM beacon) carries the AP energy-saving information.

[0069] In some application embodiments, the access point energy saving information is carried by an access point target wakeup field of a broadcast target wakeup frame, wherein the access point energy saving information carried by the access point target wakeup field includes at least an access point target wakeup enabling time and an access point target wakeup enabling link set.

[0070] In an embodiment of the present application, the access point energy saving information can be transmitted through a broadcast target wakeup frame, and the access point energy saving information can be filled into the access point wakeup field of the broadcast target wakeup frame. The access point energy saving information filled into the access point wakeup field can at least include the access point target wakeup enabling time and the access point target wakeup enabling link set.

[0071] In an exemplary implementation, a device energy saving method for AP energy saving may include the following steps:

[0072] Step 1: The AP or the sub-AP in the AP MLD determines the AP energy saving information based on the following information:

[0073] (1) Determine at least one of the following energy-saving information of the AP according to the periodic traffic map of the STAs associated on the current link or the energy-saving information of the Broadcast TWT added by the associated STAs: the next wake-up time point of the AP, the wake-up duration of the AP, and the wake-up time interval of the AP;

[0074] (2) Determine the time point for enabling the AP energy saving function according to the DTIM count. The enabling time may be such that the AP carries the AP energy saving information until the next DTIM beacon, so that all managed STAs can obtain the AP energy saving information.

[0075] (3) Determine link information on which the AP energy saving information takes effect based on links that use the same AP energy saving information in the AP MLD.

[0076] Step 2: The AP or the AP in the MLD announces the AP energy saving information by broadcast or unicast. The AP energy saving information includes one or more of the following information: the next wake-up time of the AP, the wake-up duration of the AP, the wake-up time interval of the AP, the link information on which the AP energy saving information takes effect, and the time point when the AP energy saving function is enabled.

[0077] Step 3: The AP switches to the awake state at a first time point, and exchanges frames with the STA within the awake duration; the AP switches to the sleep state or the non-awakened state at a second time point, and the STA cannot exchange frames with the AP or can only exchange frames with restrictions, wherein the first time point is the awake time point announced by the AP, and the second time point is the end time point of the frame exchange between the AP and the STA or the end time point of the AP awake duration;

[0078] A STA supporting the energy-saving function can exchange frames with the AP during the AP wake-up duration, but cannot exchange frames with the AP outside the wake-up time or can only exchange frames in a restricted manner, where the restricted frame exchange includes the initialization frame exchange and the response frame exchange corresponding to the initialization frame;

[0079] For a STA that does not support the energy-saving function, the AP can perform one of the following operations on the STA before enabling the energy-saving function:

[0080] (1) The AP actively associates with the STA port;

[0081] (2) The AP guides the STA to perform roaming operations through the BTM request method;

[0082] (3) EHT non-AP MLD that supports the EHT MLO function. The AP MLD can guide link switching through ML reconfiguration.

[0083] Step 4: The AP can actively exit the energy-saving function or the STA can interact with the AP through a specific frame to make the AP exit the energy-saving function; the AP exits the energy-saving function, and the beacon no longer carries the AP energy-saving information or indicates in the beacon that the AP energy-saving function is turned off.

[0084] Based on the above application embodiment, the Broadcast TWT Parameter Set fieldformat can be expanded, and energy-saving information can be transmitted through the Broadcast TWT protocol, see Figure 4 , you can add the AP TWT Info field in the BroadcastTWT frame structure to describe the AP energy saving information, see Figure 5The AP energy saving information may include the access point target wakeup enablement time and the access point target wakeup enabled link set. In the AP TWT Info field, the AP TWTenablement time indicates the maximum number of TBTTs from the time the AP turns on the AP TWT function; the AP TWT enabled link set indicates the link set or link mapping enabled by the AP energy saving function.

[0085] See also Figure 6 as well as Figure 7 , you can add code 5 in the Broadcast TWT Recommendation, and when the code is 5, it means that the Broadcast TWT is AP TWT.

[0086] In another exemplary embodiment, see Figure 8 , take the energy saving process of an AP or a single sub-AP in MLD as an example:

[0087] 1. AP determines the following energy-saving information of AP according to the periodic traffic map of the currently associated STAs, including: the next wake-up time point of AP, the wake-up duration of AP, and the wake-up time interval of AP; for example, STA1 has frame interaction with AP 50ms-60ms after the current TBTT, with a period of 200ms; STA2 has frame interaction with AP 40ms-50ms after the current TBTT, with a period of 400ms; then AP determines according to the periodic traffic map information of the above STAs: the next wake-up time point of AP is 40ms after TBTT, the wake-up duration of AP is 20ms, and the wake-up time interval of AP is 200ms.

[0088] 2. The AP carries the AP TWT IE in the beacon to inform the AP in advance that it will enter the energy-saving mode, and the AP enables the AP TWT function at the DTIM beacon specified by the AP TWTenablement time.

[0089] 3. The AP enters the sleep state before the next wake-up time point arrives, and enters the wake-up state to exchange frames with the STA when the next wake-up time point arrives. When the frame exchange between the AP and the STA is completed or the AP wake-up duration ends, the AP enters the sleep state again.

[0090] 4. The AP remains in sleep mode until the next wake-up cycle arrives, when it wakes up and sends a beacon to start a new round of energy-saving scheduling.

[0091] 5. At a certain point in time, the AP senses the change in the downlink data cache information and actively exits the energy-saving function: the AP remains in the active state and the AP does not carry the AP energy-saving information in the beacon.

[0092] In another exemplary embodiment, the device energy saving process may include the following steps:

[0093] 1. AP determines the following energy-saving information of AP according to the broadcast TWT parameter information added by the currently associated STAs, including: the next wake-up time of AP, the wake-up duration of AP, and the wake-up time interval of AP; such as STA1 joins broadcast TWT 1 (target wake time=20ms, duration=30ms, wake interval=200ms); STA2 joins broadcast TWT 2 (target wake time=10ms, duration=20ms, wake interval=300ms); then AP determines according to the broadcast TWT information added by the above STAs: the next wake-up time of AP is 10ms after TBTT, the wake-up duration of AP is 40ms, and the wake-up time interval of AP is 100ms.

[0094] 2. The AP carries the AP TWT IE in the beacon to inform the AP in advance that it will enter the energy-saving mode, and the AP enables the AP TWT function at the DTIM beacon specified by the AP TWTenablement time.

[0095] 3. The AP enters the sleep state before the next wake-up time point arrives, and enters the wake-up state to exchange frames with the STA when the next wake-up time point arrives. When the frame exchange between the AP and the STA is completed or the AP wake-up duration ends, the AP enters the sleep state again.

[0096] 4. The AP remains in sleep mode until the next wake-up cycle arrives, when it wakes up and sends a beacon to start a new round of energy-saving scheduling.

[0097] 5. At a certain point in time, the AP senses the change in the downlink data cache information and actively exits the energy-saving function: the AP remains in the active state and the AP does not carry the AP energy-saving information in the beacon.

[0098] In another exemplary embodiment, the device energy saving process may include the following steps: 1. The AP determines the following energy saving information of the AP based on the periodic traffic map of the currently associated STAs, including: the next wake-up time point of the AP, the wake-up duration of the AP, and the wake-up time interval of the AP; for example, STA1 has frame interaction with the AP 50ms-60ms after the current TBTT, with a period of 200ms; STA2 has frame interaction with the AP 40ms-50ms after the current TBTT, with a period of 400ms; then the AP determines based on the periodic traffic map information of the above STAs: the next wake-up time point of the AP is 40ms after the TBTT, the wake-up duration of the AP is 20ms, and the wake-up time interval of the AP is 200ms.

[0099] 2. The AP carries the AP TWT IE in the beacon to inform the AP in advance that it will enter the energy-saving mode, and the AP enables the AP TWT function at the DTIM beacon specified by the AP TWTenablement time.

[0100] 3. The AP enters the sleep state before the next wake-up time point arrives, and enters the wake-up state to exchange frames with the STA when the next wake-up time point arrives. When the frame exchange between the AP and the STA is completed or the AP wake-up duration ends, the AP enters the sleep state again.

[0101] 4. The AP remains in sleep mode until the next wake-up cycle arrives, when it wakes up and sends a beacon to start a new round of energy-saving scheduling.

[0102] 5. At a certain point in time, the STA senses the change in uplink cache information and causes the AP to exit the energy-saving function through restrictive frame interaction during the AP non-awakening period: the AP remains in the active state and the AP indicates in the beacon that the above-mentioned AP energy-saving function has been turned off.
