Description
Technical Field
The invention relates to the technical field of wireless communication, in particular to an AP energy-saving method, an AP energy-saving device and an AC.
Background
In a Wireless Local Area Network (WLAN) networking environment, a Wireless terminal realizes Access to a WLAN by connecting to an Access Point (AP). The AP provides access service for the wireless terminal, and for a certain wireless service, the AP broadcasts a Beacon frame (Beacon frame) periodically according to fixed radio frequency transmission power, and after the wireless terminal monitors the Beacon frame, the corresponding wireless service is obtained by analyzing the Beacon frame, so that whether the AP is accessed or not is determined.
Because the wireless terminals using the wireless service do not exist in the radio frequency range of the AP all the time, and the energy consumption of the AP is closely related to the radio frequency transmission power, if the wireless terminals using the wireless service do not exist in the radio frequency range of the AP, but the AP still broadcasts the Beacon frame periodically according to the fixed radio frequency transmission power, the AP consumes a large amount of energy, and especially for the AP using the battery for power supply, the service life of the battery is seriously affected.
In order to solve the above problems, in the corresponding AP energy saving method, the AP monitors the wireless terminals accessed by the AP itself, and if it is determined that the number of the wireless terminals accessed to a certain AP is zero, the energy saving of the AP can be achieved by reducing the radio frequency transmission power of the AP. However, since there may be a wireless terminal near the AP that does not temporarily need the wireless service of the WLAN to which the AP belongs, if the radio frequency transmission power is reduced too low, the wireless terminal is not in the radio frequency range of the AP, and thus cannot access the AP, which affects the wireless terminal to use the wireless service. Therefore, in the AP power saving method, the rf transmission power is not usually reduced too low, which makes the AP have poor actual power saving effect.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to improve the energy saving effect of the AP, embodiments of the present invention provide an AP energy saving method and apparatus, and an AC.
In a first aspect, an AP energy saving method provided in an embodiment of the present invention is introduced.
An execution main body of the AP power saving method provided in the embodiments of the present invention may be an Access Controller (AC), where the AC at least includes a core processing chip capable of implementing a control function. The method for implementing the AP power saving method provided by the embodiment of the present invention may be at least one of software, hardware circuit and logic circuit provided in the AC.
As shown in fig. 1, for an AP energy saving method provided in an embodiment of the present invention, the AP energy saving method may include the following steps:
s101, acquiring the number of wireless terminals accessed by each AP in a pre-created virtual service area.
The virtual service area is one or more areas created on the AC based on a pre-configuration, and each virtual service area includes a plurality of APs therein. The APs in the virtual service area comprise a plurality of pre-designated service APs, the service APs provide access services for users, and the working modes of the service APs may comprise a service mode and an energy saving mode. In the service mode, the service AP provides access service for the wireless terminal through broadcasting the Beacon frame, and the wireless terminal realizes the use of the wireless service of the WLAN through accessing the service AP; in the energy-saving mode, the serving AP stops providing access services.
Optionally, the APs in the virtual service area may further include at least one pre-designated scanning AP, and the operation modes of the scanning AP also include two types: service mode and scan mode. In the service mode, the scanning AP is the same as the service AP, access service is provided for the wireless terminal through broadcasting the Beacon frame, and the wireless terminal realizes the use of the wireless service of the WLAN through accessing the scanning AP; during the period that the service AP stops providing the access service, the working mode of the scanning AP is switched to the scanning mode, and the scanning AP can discover whether a wireless terminal enters the virtual service area or not through scanning.
When a wireless terminal accesses to an AP in a virtual service area, the AP automatically counts the number of the accessed wireless terminals, the AC acquires the number of the wireless terminals accessed by each AP, the number of the accessed wireless terminals counted by the AC can be sent to the AC by the AC through issuing an instruction when the AP receives the instruction, and the number of the accessed wireless terminals counted in the interval can be actively sent to the AC by the AP according to a preset interval.
Optionally, in step S101, the number of wireless terminals accessed by each AP in the pre-created virtual service area is obtained, which may specifically be:
and acquiring the number of wireless terminals accessed by each AP in the pre-established virtual service area according to a preset interval.
The AC may acquire the number of wireless terminals accessed by each AP according to a preset interval, for example, the number is acquired every 5 minutes. Since the wireless terminal generally does not change for a short time, e.g., 1 second, the preset interval is not set too short; however, if the preset interval is set too long, the change in the middle of the wireless terminal cannot be accurately reflected, and therefore, the preset interval is usually set to be relatively moderate.
And S102, if the number of the wireless terminals accessed by each AP is zero, sending a standby energy-saving starting instruction to each service AP so as to enable each service AP to stop providing access service.
If the number of the wireless terminals accessed by each AP in the virtual service area is zero, the fact that no wireless terminal needing to use the wireless service of the WLAN to which any AP belongs exists in the virtual service area is indicated. Since the virtual service area includes a plurality of APs, wireless services of WLANs to which the plurality of APs respectively belong may be different, and in this case, it is basically determined that there is no wireless terminal in the virtual service area. Therefore, the standby energy-saving starting instruction can be issued to each service AP, so that each service AP can enter a standby state, and in the standby state, the service AP can stop providing access service by closing the radio frequency.
Compared with the traditional AP energy-saving method, the AP can not determine whether the wireless terminal which does not need to be accessed currently exists nearby, and in order to ensure that the wireless terminal can be normally accessed when the wireless terminal needs to be accessed, the radio frequency transmitting power is only reduced, but the access service is not stopped, and the embodiment of the invention can directly enable the service AP to stop providing the access service. Therefore, compared with the traditional AP energy-saving method, the energy-saving method provided by the embodiment of the invention can save energy to a greater extent and has better energy-saving effect.
If the number of the wireless terminals accessed by each AP is obtained according to the preset interval, optionally, in step S102, a standby energy saving starting instruction is sent to a plurality of serving APs, which may specifically be:
counting the total number of the wireless terminals accessed in the virtual service area when the number of the wireless terminals accessed in each AP in the virtual service area is obtained each time;
and if the number of times that the total number is continuously zero reaches the preset number, sending a standby energy-saving starting instruction to each service AP.
Because the position of the wireless terminal is not fixed, the wireless terminal may be located within the radio frequency range of one AP, within the blind area, or within the radio frequency range of another AP. Therefore, in order to avoid the above situations and ensure the accuracy of detection, when the number of the wireless terminals accessed by each AP is obtained each time, the total number of the wireless terminals accessed in the virtual service area may be counted, and if the total number counted for the consecutive preset times is zero, for example, the total number counted for the consecutive 3 times is zero, it indicates that there is no wireless terminal in the virtual service area, and then a standby energy saving starting instruction may be issued to each serving AP.
By applying the embodiment, by acquiring the number of the wireless terminals accessed by each AP in the pre-created virtual service area, if the number of the wireless terminals accessed by each AP is zero, a standby energy saving starting instruction is sent to each service AP pre-specified in the virtual service area, so that each service AP stops providing access service to the wireless terminal. Because the number of the wireless terminals accessed by each AP in the virtual service area is zero, the wireless terminals do not exist in the virtual service area, and then a standby energy-saving starting instruction is issued to each service AP, each service AP enters a standby state together and stops providing access service, so that energy conservation is realized to a greater extent, and the energy-saving effect is improved.
When the AP achieves the energy saving purpose by reducing the radio frequency transmission power, the problem of an AP coverage blind area increase may be brought, as shown in fig. 2a, when there are wireless terminals accessed to the first AP210 and the second AP220, the radio frequency transmission power of the AP is large, the coverage of the wireless service is also large, and the blind area in the area is small, as shown in fig. 2b, when there is no wireless terminal accessed to the first AP210 and the second AP220, the radio frequency transmission power of the AP becomes small, the coverage of the wireless service also becomes small, and therefore the blind area in the area may become large.
Further, in order to improve the energy saving effect of the AP and prevent the blind area problem of the wireless service, an embodiment of the present invention further provides an AP energy saving method, as shown in fig. 3, the AP energy saving method may include the following steps:
s301, acquiring the number of wireless terminals accessed by each AP in the pre-created virtual service area.
The APs in the virtual service area include at least one pre-designated scanning AP in addition to the plurality of serving APs in the embodiment shown in fig. 1. The designation of the scanning AP may be AC AP-based location designation, for example, designating an AP near the edge of the virtual service area as the scanning AP, which makes it easier to scan and identify the wireless terminal entering the area in real time; the designation of scanning for APs may also be that the AC designates in a polling manner, for example, designating AP1 and AP2 as scanning APs during time T1, designating AP3 and AP4 as scanning APs during time T2, and so on. Of course, the number of APs to be scanned in the virtual service area is not specifically limited herein, and may be one or multiple, and if more sensitive scanning and identification of the wireless terminal are required, multiple APs may be designated as scanning APs, for example, if there are 10 APs (AP1 to AP10) in the virtual service area, AP1, AP2, AP3 and AP8 may be designated as scanning APs.
Optionally, the at least one pre-designated scanning AP may be at least one AP designated by the AC in a polling manner based on a preset period from each AP in the virtual service area.
In order to ensure more sensitive scanning and identification of the wireless terminal, the designated manner of scanning APs in the virtual service area may be a polling manner, the polling manner is based on a preset period, some APs are designated as scanning APs in each preset period, other APs are designated as scanning APs in the next preset period, and the number of designated scanning APs each time may be the same or different. It should be noted that the preset period for the AC to designate the scanning of the AP may be the same as or different from the preset interval for the AC to acquire the number of the wireless terminals accessed by each AP in the embodiment shown in fig. 1.
Taking 10 APs (AP 1-AP 10) in the virtual service area as an example, as shown in fig. 4, in a first preset period, the APs 1 and 2 may be designated as scanning APs, in a second preset period, the APs 3 and 4 may be designated as scanning APs, in a third preset period, the APs 5 and 6 may be designated as scanning APs, in a fourth preset period, the APs 7 and 8 may be designated as scanning APs, and in a fifth preset period, the APs 9 and 10 may be designated as scanning APs, and then the steps are alternately cycled in sequence.
And S302, judging whether the number of the wireless terminals accessed by each AP is zero, if so, executing S303, otherwise, executing S304.
S303, sending a standby energy-saving starting instruction to each service AP so as to enable each service AP to stop providing access service; and sending a scanning instruction to each scanning AP so as to enable each scanning AP to stop providing access service and scan the wireless terminal entering the virtual service area.
If the number of the wireless terminals accessed by each AP is zero, except that the AC sends a standby energy saving starting instruction to each service AP in the embodiment shown in fig. 1, the AC also sends a scanning instruction to each scanning AP, after receiving the scanning instruction, the scanning AP switches the working mode to the scanning mode, that is, stops providing access service, and scans the wireless terminals entering the virtual service area, the scanning mode may be a broadcast message, if the wireless terminals exist in the virtual service area, the information may reply to the scanning AP, and the information may carry the address, signal strength and other information of the wireless terminals, and after receiving the information, the scanning AP may determine that the wireless terminals exist in the virtual service area.
After the AP is scanned to determine that a wireless terminal is present in the virtual service area, scanning information is sent to the AC, where the scanning information is used to notify the AC that a wireless terminal is present in the virtual service area, and the scanning information may carry information such as an address and signal strength of the present wireless terminal. Therefore, optionally, after step S303, it may further perform:
if receiving the scanning information of the wireless terminal scanned and sent by any scanning AP, sending a scanning ending instruction to each scanning AP so as to enable each scanning AP to start access service; and sending a standby energy-saving ending instruction to each service AP so as to enable each service AP to start access service.
If the scanning information is received, it is determined that a wireless terminal which may use the wireless service appears in the virtual service area, and in order to ensure that the wireless terminal can access the AP in time to use the wireless service provided by the WLAN, a scanning ending instruction needs to be sent to each scanning AP, and a standby energy-saving ending instruction needs to be sent to each service AP, so that each scanning AP and each service AP can start the access service, thereby effectively preventing the problem of a service blind area.
S304, each service AP keeps the original access service.
If the wireless terminal accessed by at least one AP in the virtual service area is not zero, the wireless terminal in the virtual service area is indicated to use the wireless service. In order to ensure that the wireless terminal can still normally access the wireless service in the moving process, namely, the wireless service of the WLAN to which the AP belongs can be normally used in the radio frequency range of the wireless terminal moving to another AP, so that the radio frequency transmission power of each AP is not reduced, and the original access service is still kept unchanged.
By applying the embodiment, by acquiring the number of the wireless terminals accessed by each AP in the pre-created virtual service area, if the number of the wireless terminals accessed by each AP is zero, a standby energy saving starting instruction is sent to each service AP pre-specified in the virtual service area, so that each service AP stops providing access service to the wireless terminal. Because the number of the wireless terminals accessed by each AP in the virtual service area is zero, the wireless terminals do not exist in the virtual service area, and then a standby energy-saving starting instruction is issued to each service AP, each service AP enters a standby state together and stops providing access service, so that energy conservation is realized to a greater extent, and the energy-saving effect is improved. In addition, by setting the scanning AP, the wireless terminal entering the virtual service area can be scanned in the time period when the service AP stops providing the access service, thereby preventing the problem of service blind areas of the service AP.
For convenience of understanding, the AP power saving method provided by the embodiment of the present invention is described below with reference to specific examples.
As shown in fig. 5, there are 10 APs, which are APs 1-AP 10, in a wireless environment of an office, and the AP energy saving method includes the following steps:
first, a Virtual Service Zone (abbreviated as VSZ) is created.
By pre-configuring, VSZ is created on the AC, and APs 1-10 are added to this VSZ, and an AP that is easy to scan for the wireless terminal to enter VSZ or an AP with a wider radio frequency range is designated as a scanning AP, for example, in this example, AP1 and AP10 are designated as scanning APs, and AP 2-AP 9 are designated as serving APs.
Second, the number of wireless terminals accessed by each AP in VSZ is periodically obtained.
The AC acquires the number of the wireless terminals accessed by the AP 1-AP 10 at regular time every 5 minutes, and counts the total number of the wireless terminals accessed in the virtual service area when acquiring the number of the wireless terminals accessed by the AP 1-AP 10 each time.
And thirdly, starting a standby energy-saving state.
When the total number of the wireless terminals accessed in the virtual service area counted for three times is zero, the AC sends a standby energy-saving starting command to each service AP and sends scanning commands to each scanning AP, namely sends the scanning commands to the AP1 and the AP10, so that the working modes of the AP1 and the AP10 are switched to the scanning mode, and the wireless terminals entering the virtual service area are scanned; and sending a standby energy-saving starting command to the APs 2-9, so that the working modes of the APs 2-9 are switched to the standby mode, and the access service is stopped.
And fourthly, recovering the state.
When the AP1 or the AP10 scans the wireless terminal, the operation modes of the AP1 and the AP10 are switched from the scanning mode to the service mode, and the operation modes of the APs 2 to 9 are switched from the standby mode to the service mode, that is, the APs 1 to 10 are all switched to access the service.
In the scheme, by creating the VSZ, the AC acquires VSZ the number of wireless terminals accessed by each AP at regular time, and if the number of wireless terminals accessed by each AP is zero, sends a start standby power saving instruction to each service AP pre-designated in VSZ, so that each service AP stops providing access service to the wireless terminal. Since the number of the wireless terminals accessed by each AP in VSZ is zero, it can be determined that no wireless terminal exists in VSZ, and then a start standby energy saving instruction is issued to each service AP, and each service AP enters a standby state and stops providing access service, so that energy saving is achieved to a greater extent, and the energy saving effect is improved. And, by scanning the AP designated in advance, the wireless terminal entering VSZ can be scanned during the time period when the serving AP stops providing access service, thereby preventing the problem of a service shadow of the AP.
Based on the method embodiment of the first aspect, an embodiment of the present invention further provides an AP energy saving device, as shown in fig. 6, where the AP energy saving device may include:

By applying the embodiment, by acquiring the number of the wireless terminals accessed by each AP in the pre-created virtual service area, if the number of the wireless terminals accessed by each AP is zero, a standby energy saving starting instruction is sent to each service AP pre-specified in the virtual service area, so that each service AP stops providing access service to the wireless terminal. Because the number of the wireless terminals accessed by each AP in the virtual service area is zero, the wireless terminals do not exist in the virtual service area, and then a standby energy-saving starting instruction is issued to each service AP, each service AP enters a standby state together and stops providing access service, so that energy conservation is realized to a greater extent, and the energy-saving effect is improved.

In this embodiment, the processor 701 can realize that: by acquiring the number of wireless terminals accessed by each AP in a pre-created virtual service area, if the number of the wireless terminals accessed by each AP is zero, a standby energy-saving starting instruction is sent to each service AP pre-designated in the virtual service area, so that each service AP stops providing access service for the wireless terminals. Because the number of the wireless terminals accessed by each AP in the virtual service area is zero, the wireless terminals do not exist in the virtual service area, and then a standby energy-saving starting instruction is issued to each service AP, each service AP enters a standby state together and stops providing access service, so that energy conservation is realized to a greater extent, and the energy-saving effect is improved.
