Description

Energy-saving control method and related equipment

Technical Field

The present application relates to the field of energy conservation of devices, and in particular, to an energy conservation control method and related devices.

Background

A Wireless Local Area Network (WLAN) is a Network formed by replacing part or all of transmission media in a wired Local Area Network with Wireless channels of various radio waves (such as laser, infrared, radio frequency, and the like). In a WLAN, Stations (STA) access the network through Access Points (AP). The most common STA in life is a mobile phone, and a battery-powered STA like the mobile phone has strong energy-saving requirements due to the requirement on standby time. If there is no traffic, the handset will go to sleep and turn off the transceiver to save power.

When the STA transmits data to the AP, the STA indicates the power saving state with 1bit in a Media Access Control (MAC) frame header. If the bit is 1, it indicates that the STA will switch to the power saving state after sending the data frame, but in the data frame sent to the STA by the AP, the 1bit will be ignored. That is, if the STA determines that no message is sent to the AP, the STA switches to the power saving state. However, after the STA is switched to the energy saving state, the AP may still have data to be sent to the STA, which may cause a delay to the transmission of the service and affect the user experience.

Detailed Description

The embodiment of the application provides an energy-saving control method and related equipment, whether an STA is switched to an energy-saving state is no longer determined by a single STA, and whether the STA is switched to the energy-saving state is finally determined by referring to the energy-saving requirement of an AP.

The terms "first," "second," "third," "fourth," and the like in the description and claims of this application and in the above-described drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The present application is mainly applied to Wireless Local Area Networks (WLANs) which are networks formed by replacing part or all of transmission media in a wired local area network with wireless channels of various radio waves (such as laser, infrared, radio frequency, etc.), and the standard adopted by the current WLANs is IEEE802.11 series. WLAN systems we commonly use include Wi-Fi and bluetooth, etc.

Fig. 1 is a schematic diagram of a wireless local area network system. A WLAN may include multiple Basic Service Sets (BSSs), where All Stations (STAs) associate with an Access Point (AP), and the AP controls and dominates the transmission process of all data in the entire BSS, that is, all STAs in a wireless network need to communicate via the AP. As shown in fig. 1, a BSS includes an AP and three STAs (STA1, STA2, and STA 3).

The AP is an access point of a wireless network, and is commonly referred to as a "hot spot". The integrated device executes access and routing work, the pure access device is only responsible for access of a wireless client, the pure access device is usually used as a wireless network extension and connected with other APs or a main AP to expand a wireless coverage range, and the integrated device is generally the core of the wireless network. Specifically, the AP may be a Device that integrates an AP function, such as a wireless router, a Digital Subscriber Line Customer Premise Device (DSL CPE), a Cable Modem (CM), and an Optical Network Unit (ONU).

The STA represents a device connected to a wireless network, and the device may communicate with other internal devices or external devices of the wireless network through the AP, and is generally a client in the WLAN, and may be a computer equipped with a wireless network card, or a smart phone with a WiFi module, and may be mobile or fixed, and is a basic component unit of a wireless local area network. The most common STA device is a mobile phone, and like a mobile phone, a STA with a large traffic but powered by a battery has a strong demand for power saving due to the standby time requirement. Therefore, if there is no traffic, the handset will go to sleep and turn off the transceiver to save power.

In the current IEEE802.11 standard, an STA generally determines whether to switch to a power saving state according to whether it has data to transmit to an AP. However, after the STA is switched to the energy saving state, the AP may still have data to be sent to the STA, which may cause a delay to the transmission of the service and affect user experience.

Therefore, the application provides an energy-saving control method. Fig. 2 is a schematic diagram of an embodiment of the energy saving control method in the present application. In this embodiment, the energy saving control method includes the following steps.

201. And the AP determines first energy-saving information of the STA according to the service information of the service sent to the STA by the AP.

In this embodiment, the first energy saving information includes permission of energy saving or prohibition of energy saving. The AP may determine whether the first power saving information allows or prohibits power saving by the traffic information of the traffic transmitted to the STA. Specifically, the service information includes at least one of a delay requirement of the service, historical traffic statistics of the service, a sending frequency of the service, and a remaining amount of the service in the cache. For example, there are services sensitive to delay, such as voice, currently, and if the STA switches to the energy saving state, the user experience may be very affected, then the AP determines that the first energy saving information is energy saving prohibition. For another example, if the AP deduces that a large amount of traffic still needs to be sent to the STA after the historical traffic statistics of the traffic, the AP determines that the first power saving information is power saving prohibition. For another example, if the AP predicts that traffic still needs to be transmitted to the STA soon (e.g., within 10 ms) through the transmission frequency of the traffic, the AP determines that the first power saving information is power saving prohibition. For another example, if a large amount of traffic remains in the cache of the AP, the AP determines that the first power saving information is power saving prohibition.

It should be noted that, in practical applications, the basis for the AP to determine the first energy saving information is not limited to the above listed cases, and in the case that the user experience is affected due to the STA switching to the energy saving state, the AP determines that the first energy saving information is energy saving prohibition.

202. And the AP generates a data frame according to the first energy-saving information.

In this embodiment, the AP extracts the packet from the cache, and encapsulates the packet to obtain the data frame. Wherein the data frame includes a frame control (frame control) field, and the AP indicates the first power saving information through a power management (power management) field in the frame control field.

Specifically, the type of the data frame may be a Media Access Control (MAC) frame. Fig. 3 is a frame structure diagram of a MAC frame. The MAC Frame includes a Frame header (MAC header), a Frame Body (Frame Body), and a Frame Check Sequence (FCS). The frame body, also referred to as data bits, is responsible for transmitting upper layer data between stations. The frame check sequence is used for the STA to check the integrity of the received frame. The Frame header further includes a Frame Control field (Frame Control), a Duration field (Duration/ID), four address fields (address 1, address 2, address 3, and address 4), and a Sequence Control field (Sequence, Control).

Further, the frame control field further includes a plurality of fields. Fig. 4 is a diagram illustrating a structure of a frame control field. The Frame control field includes a Protocol Version (Protocol Version), a Type (Type), a Subtype (Subtype), To distribution system (To DS), From distribution system (From DS), More Fragments (More Fragments), Retry (Retry), energy Management (Power Management), More Data (More Data), Protected frames (Protected Frame), and Order (Order).

The energy management domain occupies one bit, and the AP can use the bit to indicate the first energy saving information. Specifically, if the bit is 1, it indicates that energy saving is allowed, and if the bit is 0, it indicates that energy saving is prohibited.

It should be noted that, according to the existing standard, the energy management field in the data frame sent by the STA to the AP has a practical meaning, and the energy management field in the data frame sent by the AP to the STA is left unused. Thus, the AP may use the energy management domain in this application to indicate power saving information that the AP communicates to the STA.

203. The AP transmits a data frame to the STA.

204. And the STA acquires local second energy-saving information.

In this embodiment, the STA locally further includes second energy saving information, where the second energy saving information also includes permission of energy saving or prohibition of energy saving. For example, if the STA currently has data to send to the AP, the second power saving information is to prohibit power saving. If the STA does not currently have data to send to the AP, the second power saving information is to allow power saving.

205. And the STA determines whether to switch to the energy-saving state according to the first energy-saving information and the second energy-saving information.

In this embodiment, the first energy saving information may be identical to the second energy saving information, or a conflict may occur. The operations performed by the STA differ in different situations. The following are introduced separately:

the first, first and second energy saving information are all energy saving-allowed.

In this case, the AP and the STA may not have data to transmit to the other side at present, and the STA may switch to the power saving state.

And the second type, the first energy saving information and the second energy saving information are energy saving forbidding.

In this case, both the AP and the STA still have data to transmit to each other, and the STA needs to stay awake, that is, the STA can still transmit and receive data.

And thirdly, the first energy-saving information is energy conservation forbidding, and the second energy-saving information is energy conservation permission.

In this case, the STA may not have data to send to the AP, but the AP still has data to send to the STA, and the STA needs to ensure to remain awake when the AP still has data to send, that is, the STA cannot switch to the power saving state.

And fourthly, the first energy-saving information is energy saving permission, and the second energy-saving information is energy saving prohibition.

In this case, the AP may have no data to transmit to the STA, but the STA still has data to transmit to the AP and the STA still remains awake.

In summary, if the first energy saving information is identical to the second energy saving information, the STA performs according to the first energy saving information or the second energy saving information. If the first energy saving information conflicts with the second energy saving information, that is, one party allows energy saving and the other party prohibits energy saving, the STA should remain in an awake state in order to ensure smooth data transmission and reception.

Optionally, before the step 201, capability negotiation between the STA and the AP is also required. Referring to fig. 5, fig. 5 is a schematic diagram of another embodiment of the energy saving control method in the present application. In this embodiment, the energy saving control method includes the following steps.

501. The STA negotiates capabilities with the AP.

In this embodiment, during the process of establishing communication between the STA and the AP, the STA and the AP perform capability negotiation to know the functions supported by each other. Specifically, the STA transmits its own first capability information set to the AP, and the AP transmits its own second capability information set to the STA. The first capability information set comprises identification capability of the STA on the first energy saving information, and the second capability information set comprises capability of the AP indicating the first energy saving information through a data frame. After the capability negotiation, the STA and the AP can acquire the common capability of the two parties.

Optionally, in the capability negotiation process, the AP may also negotiate with the STA which energy saving information is subject to when the first energy saving information and the second energy saving information collide. Reference may be specifically made to the description related to step 204, which is not described herein again.

502. And the AP determines first energy-saving information of the STA according to the service information of the service sent to the STA by the AP.

In this embodiment, step 502 is similar to step 201 in the embodiment shown in fig. 2, and details are not repeated here.

503. And the AP generates a data frame according to the first energy-saving information.

In this embodiment, step 503 is similar to step 202 in the embodiment shown in fig. 2, and detailed description thereof is omitted here.

Optionally, the AP may also add an extension field in the data frame and use the extension field to indicate the power saving level of the power saving state. That is, the power saving state of the STA corresponds to a plurality of power saving levels, and different power saving levels indicate how deep the STA enters the sleep mode. Specifically, the power saving level includes at least one of a rate of frames that the STA can receive in the power saving state, a duration for which the STA switches to the power saving state, and a frequency at which the STA switches to the power saving state. For example, the higher the power saving level, the smaller the rate of frames that can be received by the STA, the longer the time period for which the STA switches to the power saving state, or the higher the frequency with which the STA switches to the power saving state.

It should be noted that the power saving level is not limited to the above listed types, and all cases that can distinguish how deep the STA enters the sleep mode can be regarded as the power saving level.

The following describes the extension field in the data frame, and specifically, the type of the data frame is the MAC frame as an example. Fig. 6 is a diagram illustrating another frame structure of a MAC frame. The difference from the MAC frame shown in fig. 3 is that the frame header part further includes a Quality of Service Control field (Quality of Service Control) and a High Throughput field (High Throughput Control). The extension field in this embodiment may be the qos control field or the high throughput field.

It is understood that, if the AP needs to indicate the power saving level through the extension field, in step 501, the first capability information set of the STA further includes the capability of identifying the power saving level, and the second capability information set of the AP further includes the capability of indicating the power saving level through the extension field.

504. The AP transmits a data frame to the STA.

505. And the STA acquires local second energy-saving information.

506. And the STA determines whether to switch to the energy-saving state according to the first energy-saving information and the second energy-saving information.

In this embodiment, step 506 is similar to step 205 in the embodiment shown in fig. 2, and detailed description thereof is omitted here.
