Description

An energy-saving control method and related equipment

technical field

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

Background technique

A wireless local area network (Wireless Local Area Network, WLAN) is a network formed by replacing some or all of the transmission media in a wired local area network with wireless channels of various radio waves (eg, laser, infrared, radio frequency, etc.). In a WLAN, a station (Station, STA) accesses the network through an access point (AccessPoint, AP). The most common STA in life is a mobile phone. A battery-powered STA like a mobile phone has a strong demand for energy saving due to the requirement of standby time. If there is no traffic, the phone goes to sleep, turning off the transceiver to save energy.

When the STA sends data to the AP, the STA uses 1 bit in a media access control (Media Access Control, MAC) frame header to indicate the power saving state. If this bit is 1, it means that the STA will switch to the energy-saving state after sending the data frame, but this 1 bit will be ignored in the data frame sent by the AP to the STA. That is to say, if the STA determines that it has no packets to send to the AP, it switches to the energy-saving state. However, after the STA is switched to the energy-saving state, the AP may still have data to send to the STA, which will bring delay to service transmission and affect user experience.

SUMMARY OF THE INVENTION

Embodiments of the present application provide an energy-saving control method and related equipment.

In a first aspect, an embodiment of the present application provides an energy-saving control method. The method includes the following steps.

The STA receives the data frame sent by the AP, wherein the data frame includes a frame control field, and the energy management field in the frame control field is used to indicate the first energy saving information, and the first energy saving information is sent by the AP to the STA according to the service The service information is determined, and the first energy saving information includes enabling or disabling energy saving. In addition, the STA may also acquire local second energy saving information, where the second energy saving information also includes enabling or disabling energy saving. If the first energy saving information and the second energy saving information are the same, the STA determines whether to switch to the energy saving state according to the first energy saving information or the second energy saving information. For example, if the first energy saving information and the second energy saving information both allow energy saving, the STA switches for the energy saving state. If the first energy saving information and the second energy saving information are different, then the STA or the AP still has data to send to the other party, and the STA remains in an awake state.

In this embodiment, whether the STA switches to the energy-saving state is no longer determined by the STA unilaterally, and also needs to refer to the AP's requirements for energy-saving to finally determine whether to switch to the energy-saving state. This avoids the situation that the AP still needs to send data to the STA, but the STA has switched to the energy-saving state and cannot receive data, thereby improving user experience.

Optionally, in some possible implementations, the energy management field includes target bits. If the target bit is 1, the first energy saving information is that energy saving is allowed. If the target bit is 0, the first energy saving information is that energy saving is prohibited.

In this embodiment, a specific implementation manner of indicating the first energy saving information through the energy management domain is introduced, which improves the practicability of this solution.

Optionally, in some possible implementation manners, the data frame further includes an extension field, where the extension field is used to indicate a power saving level of the power saving state, and the power saving level includes allowing the power saving in the power saving state. At least one of the rate of frames received by the STA, the duration of the STA entering the power saving state, and the frequency of the STA entering the power saving state.

In this embodiment, the STA switches to the energy-saving state according to the indication of the data frame sent by the AP, and can also determine the energy-saving level. The energy-saving state of the STA corresponds to multiple energy-saving levels. It is convenient to adjust the energy-saving state according to the actual situation, and the flexibility of the scheme is improved.

Optionally, in some possible implementation manners, before the STA receives the data frame sent by the AP, the STA and the AP will exchange capability information. Specifically, the STA sends a first capability information set to the AP, where the first capability information set includes an identification capability of the STA for the first energy saving information. The STA receives the second capability information set sent by the AP, where the second capability information set includes the capability of the AP to indicate the first energy saving information through the data frame.

In this embodiment, the AP and the STA can determine whether the other party has the same function through the exchange of capability information. On the basis that the two parties have the same function, the AP sends a data frame for indicating the first energy saving information to the STA. Significantly, the situation in which the STA cannot refer to the AP's energy saving information to save energy due to the lack of consensus between the two parties is avoided.

Optionally, in some possible implementations, the first capability information set sent by the STA to the AP may include, in addition to the STA's ability to identify the first energy saving information, the STA's ability to identify the energy saving level. Similarly, the second capability information set sent by the AP to the STA may include, in addition to the capability of the AP indicating the first energy saving information through the data frame, the capability of the AP indicating the energy saving level through the data frame.

In this embodiment, the capability information interaction between the STA and the AP also includes the energy saving level, which improves the scalability of the solution.

Detailed ways

The embodiments of the present application provide an energy-saving control method and related equipment. Whether the STA switches to the energy-saving state is no longer determined by the STA alone. It is also necessary to refer to the AP's requirements for energy-saving to finally determine whether to switch to the energy-saving state. This avoids the situation that the AP still needs to send data to the STA, but the STA has switched to the energy-saving state and cannot receive data, thereby improving user experience.

It is to be understood that the data so used may be interchanged under appropriate circumstances such that the embodiments of the application described herein can, for example, be practiced in sequences other than those illustrated or described herein. Furthermore, the terms "comprising" and "having" and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those expressly listed Rather, those steps or units may include other steps or units not expressly listed or inherent to these processes, methods, products or devices.

This application is mainly applied to wireless local area networks (WLAN), which is formed by replacing some or all of the transmission media in wired local area networks with wireless channels of various radio waves (such as laser, infrared, radio frequency, etc.). Network, the current standard adopted by WLAN is the IEEE802.11 series. The WLAN systems we usually use include Wi-Fi and Bluetooth.

FIG. 1 is a schematic diagram of a wireless local area network system. WLAN can include multiple basic service sets (basic service sets, BSS). In BSS, all stations (station, STA) are associated with an access point (AccessPoint, AP), and the AP controls and dominates all data in the entire BSS. The transmission process, that is, all STAs in the wireless network have to go through the AP if they want to communicate. As shown in Figure 1, it is a BSS, including one AP and three STAs (STA1, STA2 and STA3).

An AP is an access point to a wireless network, commonly known as a "hotspot". There are mainly routing, switching and access integrated devices and pure access point devices. The integrated device performs access and routing work. The pure access device is only responsible for the access of wireless clients. The pure access device is usually used as a wireless network extension. Or the main AP is connected to expand the wireless coverage, and the all-in-one device is generally the core of the wireless network. Specifically, the AP may be a wireless router, a digital subscriber line customer terminal equipment (Digital Subscriber Line Customer Premise Device, DSL CPE), a cable modem (Cable Modem, CM), an optical network unit (Optical Network Unit, ONU) and other integrated AP functions. equipment.

STA represents a device connected to a wireless network. These devices can communicate with other internal devices or outside the wireless network through AP. STA is generally a client in WLAN, which can be a computer equipped with a wireless network card or a WiFi module. STA can be mobile or fixed, and it is the basic unit of wireless local area network. The most common STA device is a mobile phone. Similar to a mobile phone, a STA with large traffic but powered by a battery has a strong demand for energy saving due to standby time requirements. Therefore, if there is no traffic, the phone goes to sleep, turning off the transceiver to save energy.

In the current IEEE 802.11 standard, the STA usually decides whether to switch to the energy-saving state according to whether it has data to send to the AP. However, after the STA is switched to the energy-saving state, the AP may still have data to send to the STA, which will bring delay to service transmission and affect user experience.

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

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

In this embodiment, the first energy saving information includes enabling energy saving or prohibiting energy saving. The AP may determine whether the first energy saving information allows energy saving or prohibits energy saving through the service information of the service sent to the STA. Specifically, the service information includes at least one of the delay requirement of the service, the historical traffic statistics of the service, the sending frequency of the service, and the remaining amount of the service in the buffer. For example, there are currently delay-sensitive services such as voice. If the STA switches to the energy-saving state, the user experience will be greatly affected, and the AP determines that the first energy-saving information is prohibiting energy-saving. For another example, after the AP deduces from historical traffic statistics of services that there are still a large number of services to be sent to the STA, the AP determines that the first energy saving information is that energy saving is prohibited. For another example, the AP predicts that there are still services that need to be sent to the STA soon (for example, within 10 ms) through the sending frequency of the service, then the AP determines that the first energy saving information is that energy saving is prohibited. For another example, if there is still a large amount of services remaining in the buffer of the AP, the AP determines that the first energy saving information is that energy saving is prohibited.

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-mentioned situations. In any situation that affects the user experience due to the STA switching to the energy-saving state, the AP will determine the first energy-saving information. To prohibit energy saving.

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

In this embodiment, the AP extracts the message from the cache, and encapsulates the message to obtain the data frame. The data frame includes a frame control (frame control) field, and the AP indicates the first energy 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 (Media Access Control, MAC) frame. FIG. 3 is a schematic diagram of a frame structure of a MAC frame. A MAC frame includes a frame header (MAC header), a frame body (Frame Body) and a frame check sequence (Frame Check sequence, FCS). Among them, the frame body is also called the data bit, which is responsible for transmitting the upper layer data between the workstations. The Frame Check Sequence is used by 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).

Furthermore, the frame control field also includes a plurality of fields. FIG. 4 is a schematic structural diagram of a frame control field. The frame control field includes Protocol Version (Protocol Version), Type (Type), Subtype (Subtype), To Distributed System (To DS), From Distributed System (From Distributed System, From DS), More Fragments (More Fragments), Retry (Retry), Power Management (Power Management), More Data (MoreData), Protected Frame (Protected Frame) and Order (Order).

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

It should be noted that, according to the existing standards, the energy management field in the data frame sent by the STA to the AP has actual meaning, while the energy management field in the data frame sent by the AP to the STA is reserved. Therefore, in this application, the AP can use the energy management domain to indicate the energy saving information communicated by the AP to the STA.

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

204. The STA acquires local second energy saving information.

In this embodiment, the local STA further includes second energy saving information, where the second energy saving information also includes enabling or disabling energy saving. For example, if the STA currently has data that needs to be sent to the AP, the second energy saving information is that energy saving is prohibited. If the STA currently has no data to send to the AP, the second energy saving information is to allow energy saving.

205. 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 consistent with the second energy saving information, or a conflict may occur. In different situations, the operations performed by the STA are also different. The following are respectively introduced:

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

In this case, neither the AP nor the STA may currently have data to send to the other, and the STA can switch to the energy-saving state.

In the second type, the first energy saving information and the second energy saving information are both prohibiting energy saving.

In this case, both the AP and the STA still need to send data to each other, so the STA needs to remain awake, that is, the STA can still send and receive data.

The third type, the first energy saving information is that energy saving is prohibited, and the second energy saving information is that energy saving is allowed.

In this case, the STA may have no data to send to the AP, but the AP still has data to send to the STA. The STA needs to ensure that it remains awake when the AP still has data to send, that is, the STA cannot switch to the energy-saving state.

Fourth, the first energy saving information is to allow energy saving, and the second energy saving information is to prohibit energy saving.

In this case, the AP may have no data to send to the STA, but the STA still has data to send to the AP, and the STA still needs to remain awake.

To sum up, if the first energy saving information is consistent with the second energy saving information, the STA executes 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 needs to keep the wake-up state in order to ensure smooth data transmission and reception.

In this embodiment of the present application, the STA may receive the data frame sent by the AP, and identify the first energy saving information determined by the AP through the data frame. In addition, the STA locally includes second energy saving information, and both the first energy saving information and the second energy saving information include enabling or disabling energy saving. Further, the STA determines whether to switch to the energy-saving state in combination with the first energy-saving information and the local second energy-saving information. That is to say, whether the STA switches to the energy-saving state is no longer unilaterally determined by the STA, and also needs to refer to the AP's requirements for energy-saving to finally determine whether to switch to the energy-saving state. This avoids the situation that the AP still needs to send data to the STA, but the STA has switched to the energy-saving state and cannot receive data, thereby improving user experience.

Optionally, before the above step 201, capability negotiation needs to be performed between the STA and the AP. Please refer to FIG. 5 below, which 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 and the AP perform capability negotiation.

In this embodiment, during the process of establishing communication between the STA and the AP, the STA will conduct capability negotiation with the AP to learn the functions supported by the other party. Specifically, the STA sends its own first capability information set to the AP, and the AP sends its own second capability information set to the STA. Wherein, the first capability information set includes the ability of the STA to identify the first energy saving information, and the second capability information set includes the capability of the AP to indicate the first energy saving information through a data frame. After capability negotiation, the STA and AP can learn the common capabilities of both parties.

Optionally, in the process of capability negotiation, the AP may also negotiate with the STA which energy saving information shall prevail when the first energy saving information and the second energy saving information conflict. For details, reference may be made to the relevant description of the foregoing step 204, which will not be repeated here.

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

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

503. 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 details are not repeated 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 to say, the energy-saving state of the STA corresponds to multiple energy-saving levels, and different energy-saving levels indicate the degree to which the STA enters the sleep state. Specifically, the energy saving level includes at least one of the rate of frames that the STA can receive in the energy saving state, the duration of the STA switching to the energy saving state, and the frequency of the STA switching to the energy saving state. For example, the higher the energy saving level, the lower the frame rate that the STA can receive, the longer the time period for the STA to switch to the energy saving state or the higher the frequency for the STA to switch to the energy saving state.

It should be noted that the energy-saving level is not limited to the above-mentioned types, and any situation that can distinguish the degree of the STA entering the sleep state can be regarded as the energy-saving level.

The extended fields in the data frame are described below, specifically still taking an example that the type of the data frame is a MAC frame. FIG. 6 is a schematic diagram of 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). Wherein, the extension field in this embodiment may be the above-mentioned QoS control field or high throughput field.

It can be understood that, if the AP needs to indicate the energy saving level through the extension field, then in the above step 501, the first capability information set of the STA also includes the ability to identify the energy saving level, and the second capability information set of the AP also includes the ability to pass the energy saving. The extension field indicates the capability of the power saving level.

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

505. The STA acquires local second energy saving information.

506. 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 details are not repeated here.
