Power adjustment method, AP device and computer readable storage medium

Technical Field

Embodiments of the present invention relate to, but not limited to, the field of communications technologies, and in particular, to a power adjustment method, an AP device, and a computer-readable storage medium.

Background

For a WLAN (Wireless Local Area Network), the signal strength of an AP (Access Point) device is related to the transmission power of its WLAN device, and when the transmission power is higher, the signal strength of the WLAN device is stronger, and the signal coverage of the AP device is wider. However, when the transmission power of the WLAN device is higher, not only the power consumption of the AP device is increased, but also the AP device is heated seriously, thereby affecting the service life of the device.

In contrast, the conventional solution is to adjust the maximum transmission power of the WLAN device according to the temperature of the AP device, and when the temperature of the AP device exceeds a set temperature protection threshold, the maximum transmission power of the WLAN device is adjusted to reduce the maximum transmission power of the WLAN device, thereby reducing the energy consumption of the AP device. However, this solution merely adjusts the transmission power of the device according to the temperature of the device itself, and does not consider the working conditions of the surrounding WLAN devices, and the above-mentioned existing solution may disconnect the WLAN devices in the network during the process of reducing power consumption, thereby affecting the normal service of the whole wireless network.

The embodiment of the invention comprises the following steps: for the wireless connection condition, a first AP device is wirelessly connected to a second AP device, the first AP device acquires an RSSI value of the first AP device received by the second AP device, and then adjusts the current transmission power according to the RSSI value so as to adjust the RSSI value to a preset first RSSI threshold value; wherein the first RSSI threshold value represents a received signal quality threshold of the second AP device. According to the technical scheme of the embodiment of the invention, when the first AP equipment transmits at the current transmission power, when the RSSI value of the first AP equipment measured by the second AP equipment is higher than the first RSSI threshold value, the current transmission power of the first AP equipment is larger, so that the RSSI value of the first AP equipment measured by the second AP equipment can be reduced to the first RSSI threshold value by reducing the transmission power of the first AP equipment. In addition, when the RSSI value of the first AP device measured by the second AP device is lower than the first RSSI threshold value, it indicates that the signal strength of the area where the second AP device is located is weak, and the signal coverage of the first AP device needs to be enhanced to maintain the connection. Therefore, the embodiment of the invention can adaptively adjust the transmission power of the first AP device according to the RSSI value of the first AP device received by the second AP device and the preset first RSSI threshold value, thereby not only reducing the energy consumption of the first AP device, but also ensuring stable communication connection between the first AP device and the second AP device.

According to the technical scheme of the embodiment of the invention, as the first AP device and the third AP device are in wired connection, it is only required to ensure that other WLAN devices can keep communication connection in the area between the first AP device and the third AP device, and therefore, when the first AP device transmits with the current transmission power, when the RSSI value of the first AP device measured by the third AP device is higher than the second RSSI threshold value, that is, the third AP device is located within the edge of the current signal coverage area of the first AP device, it indicates that the current transmission power of the first AP device is higher, and therefore, the embodiment of the invention can reduce the RSSI value of the first AP device measured by the third AP device to the second RSSI threshold value by reducing the transmission power of the first AP device, so that the third AP device is located just at the edge of the signal coverage area of the first AP device. In addition, when the RSSI value of the first AP device measured by the third AP device is lower than the second RSSI threshold value, that is, the third AP device is located outside the edge of the current signal coverage area of the first AP device, it indicates that the current transmission power of the first AP device is low, which may cause that other WLAN devices cannot be in communication connection in the area between the first AP device and the third AP device. Therefore, the embodiment of the present invention can adaptively adjust the transmission power of the first AP device according to the RSSI value of the first AP device received by the third AP device and the preset second RSSI threshold value, which not only can reduce the energy consumption of the first AP device, but also can ensure that other WLAN devices can maintain communication connection in the area between the first AP device and the third AP device.

For the technical scheme, the embodiment of the invention can adaptively adjust the transmission power of the first AP device according to the RSSI value of the first AP device received by the second AP device and the preset first RSSI threshold value, and according to the RSSI value of the first AP device received by the third AP device and the preset second RSSI threshold value, so that not only can the energy consumption of the first AP device be reduced, but also the stable communication connection between the first AP device and the second AP device can be ensured, and other WLAN devices can maintain the communication connection in the area between the first AP device and the third AP device.

The embodiments of the present invention will be further explained with reference to the drawings.

As shown in fig. 1, fig. 1 is a schematic diagram of a system architecture platform for performing a power regulation method according to an embodiment of the present invention.

In the example of fig. 1, the system architecture platform includes a first AP device 100, at least one second AP device 200, and at least one third AP device 300, where the first AP device 100 and the second AP device 200 are wirelessly connected, and the first AP device 100 and the third AP device 300 are wired connected, and then the first AP device 100, the second AP device 200, and the third AP device 300 are each provided with a memory 120 and a processor 110, where the memory 120 and the processor 110 may be connected by a bus or in other manners, and fig. 1 takes the connection by a bus as an example.

The memory 120, which is a non-transitory computer readable storage medium, may be used to store non-transitory software programs as well as non-transitory computer executable programs. Further, the memory 120 may include high speed random access memory, and may also include non-transitory memory, such as at least one magnetic disk storage device, flash memory device, or other non-transitory solid state storage device. In some embodiments, memory 120 optionally includes memory located remotely from processor 110, which may be connected to the system architecture platform via a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.

In the related art, for a WLAN, the signal strength of an AP device is related to the transmission power of its WLAN device, and when the transmission power is higher, the signal strength of the WLAN device is stronger, and the signal coverage of the AP device is wider. However, when the transmission power of the WLAN device is higher, not only the power consumption of the AP device is increased, but also the AP device is heated seriously, thereby affecting the service life of the device.

Specifically, the system architecture platform shown in fig. 1 may be a WLAN Mesh (Mesh) network architecture, which is a cooperative working condition of a plurality of AP devices, each AP device has its own transmission power, and the transmitted signal forms a coverage area of the AP device. The multiple AP devices work cooperatively to expand the coverage area of a single AP device, and the formed Mesh network jointly forms a coverage area. The user can search for WLAN signals of the Mesh network in this coverage area, connect to the Mesh network and complete data service. The Mesh network has the characteristics of ad hoc network, and the increase or decrease of AP equipment in the Mesh network can affect and change the power output of the Mesh network. The existing solution only considers the working condition of the AP device itself, that is, only considers the working condition of the Mesh node itself, does not consider the cooperative working condition of the Mesh network, does not transmit the current working state of the Mesh node between nodes, and does not dynamically control the output power of the AP device according to the increase and decrease of the AP node. Wherein the Mesh node corresponds to the AP device.

In addition, the WLAN Mesh network will be described in detail with reference to fig. 2. Fig. 2 is a typical WLAN Mesh network formed by two WLAN wireless hotspots, where a downstream AP node is connected to an upstream AP node, and the connection between the upstream AP node and the downstream AP node may be a wireless WLAN connection or a wired connection. The upstream AP node and the downstream AP node have the same SSI D (Wireless network Identifier) and SSID (Service Set Identifier) Service of the Mesh network, an STA (Station, client) accesses the network through the network Service provided by the SSID, the STA is a client of the WLAN, and the STA can be switched between different AP nodes according to the current signal coverage when moving in the coverage range of the upstream AP node and the downstream AP node. The Mesh network expands the coverage area of a single AP by expanding the number of AP nodes. The more AP nodes of the Mesh network, the wider the total coverage area of the Mesh network can be. When the Mesh network moves, the STA can be switched on different AP nodes according to the current situation. Illustratively, the upstream AP node in fig. 2 may correspond to the first AP device 100 in fig. 1, and the downstream AP node in fig. 2 may correspond to the second AP device 200 and/or the third AP device 300 in fig. 1.

Therefore, based on the above situation, in the system architecture platform provided in the example of fig. 1, an embodiment of the present invention provides a power adjustment method, which dynamically adjusts the transmit power of a Mesh node according to the current topological connection state of the Mesh network, including the connection type characteristics of the node through a wireless link and a wired link, by using the characteristics of message communication of the Mesh node, and optimizes the power output of the Mesh network, reduces the energy consumption of devices, and improves the stability and reliability of the network in long-term operation on the basis of not reducing the experience of the Mesh service. Specifically, the system architecture platform provided in the example of fig. 1 includes, but is not limited to, the following three connection cases:

for the wireless connection between the first AP device 100 and the second AP device 200, the second AP device 200 may detect that the area where the second AP device is located receives the RSSI value of the first AP device 100 and send the RSSI value to the first AP device 100, and then the first AP device 100 may adjust its own transmission power according to the obtained RSSI value, because the RSSI value received by the second AP device 200 from the first AP device 100 also changes correspondingly during the adjustment of the transmission power of the first AP device 100, the transmission power of the first AP device 100 may be adjusted in the embodiment of the present invention, so that the RSSI value received by the second AP device 200 from the first AP device 100 is adjusted to be the preset first RSSI threshold value; wherein the first RSSI threshold value represents a received signal quality threshold of the second AP device 200. Therefore, according to the scheme provided by the embodiment of the present invention, the transmission power of the first AP device 100 can be adaptively adjusted according to the RSSI value of the first AP device 100 received by the second AP device 200 and the preset first RSSI threshold value, which not only can reduce the energy consumption of the first AP device 100, but also can ensure stable communication connection between the first AP device 100 and the second AP device 200.

For the wired connection between the first AP device 100 and the third AP device 300, the third AP device 300 may detect that the area where the third AP device 300 is located receives the RSSI value of the first AP device 100 and send the RSSI value to the first AP device 100, and then the first AP device 100 may adjust its own transmission power according to the obtained RSSI value, because the RSSI value received by the third AP device 300 from the first AP device 100 may also change correspondingly during the adjustment of the transmission power of the first AP device 100, in this embodiment of the present invention, the transmission power of the first AP device 100 may be adjusted so that the RSSI value received by the third AP device 300 from the first AP device 100 is adjusted to the preset second RSSI threshold value; wherein the second RSSI threshold value represents a received signal quality threshold at the edge of the signal coverage area of the first AP device 100. Therefore, according to the scheme provided by the embodiment of the present invention, the transmission power of the first AP device 100 can be adaptively adjusted according to the RSSI value of the first AP device 100 received by the third AP device 300 and the preset second RSSI threshold value, which not only can reduce the energy consumption of the first AP device 100, but also can ensure that the STA can maintain the communication connection in the area between the first AP device 100 and the third AP device 300.

For the case that the first AP device 100 is wirelessly connected to the second AP device 200 and is simultaneously connected to the third AP device 300 by wire, the second AP device 200 and the third AP device 300 can detect that the area where the first AP device 100 is located receives the RSSI value and send the RSSI value to the first AP device 100, and then the first AP device 100 adjusts its own transmission power according to the obtained RSSI value, so that the RSSI value of the first AP device 100 received by the second AP device 200 and the third AP device 300 also changes correspondingly. Since in practical cases, the distances between the second AP device 200 and the third AP device 300 and the first AP device 100 may affect the transmission power adjustment of the first AP device 100, there are two adjustment manners including, but not limited to:

the first adjustment mode is as follows: the first AP device 100 adjusts the current transmission power according to the RSSI value, so as to adjust the RSSI value received by the second AP device 200 from the first AP device 100 to a preset first RSSI threshold value, and at the same time, adjust the RSSI value received by the third AP device 300 from the first AP device 100 to be greater than or equal to a preset second RSSI threshold value.

The second adjustment mode is as follows: the first AP device 100 adjusts the current transmission power according to the RSSI value, so as to adjust the RSSI value received by the third AP device 300 from the first AP device 100 to the preset second RSSI threshold value, and at the same time, adjust the RSSI value received by the second AP device 200 from the first AP device 100 to be greater than or equal to the preset first RSSI threshold value.

Therefore, according to the scheme provided by the embodiment of the present invention, the transmission power of the first AP device 100 can be adaptively adjusted according to the RSSI value of the first AP device 100 received by the second AP device 200 and the preset first RSSI threshold value, and according to the RSSI value of the first AP device 100 received by the third AP device 300 and the preset second RSSI threshold value, so that not only the energy consumption of the first AP device 100 can be reduced as much as possible, but also the stable communication connection between the first AP device 100 and the second AP device 200 can be ensured, and the STA can maintain the communication connection in the area between the first AP device 100 and the third AP device 300.

It can be understood by those skilled in the art that the system architecture platform can be applied to a 3G communication network system, an LTE communication network system, a 5G communication network system, a mobile communication network system that is evolved later, and the like, and this embodiment is not limited in particular.

Those skilled in the art will appreciate that the system architecture platform illustrated in FIG. 1 does not constitute a limitation on embodiments of the invention, and may include more or fewer components than those illustrated, or some components may be combined, or a different arrangement of components.

In the system architecture platform shown in fig. 1, the processor 110 may call a power adjustment program stored in the memory 120 to perform a power adjustment method between the first AP device 100 and the second and

third AP devices

200 and 300.

Based on the above system architecture platform, the following provides various embodiments of the power adjustment method of the present invention.

As shown in fig. 3 and fig. 4, fig. 3 is a schematic view of a scenario of a wireless connection between a first AP device and a second AP device, and fig. 4 is a flowchart of a power adjustment method according to an embodiment of the present invention, where the power adjustment method may be applied to the first AP device in fig. 3, and the first AP device is wirelessly connected to the second AP device, and the method includes, but is not limited to, step S100 and step S200.

Step S100, obtaining an RSSI value of a first AP device received by a second AP device;

step S200, adjusting the current transmission power according to the RSSI value so as to adjust the RSSI value to a preset first RSSI threshold value; wherein the first RSSI threshold value represents a received signal quality threshold for the second AP device.

In an embodiment, the first AP device and the second AP device are wirelessly connected through the WLAN, and the RSSI value received by the second AP device from the first AP device may reflect the strength of the wireless signal currently received by the first AP device. Under the condition that the first AP device transmits at the current transmission power, when the RSSI value measured by the second AP device for the first AP device is higher than the first RSSI threshold value T _ RSSI _ CONNECTION, that is, the requirement that the second AP device and the first AP device maintain stable communication CONNECTION is far met, it indicates that the current transmission power of the first AP device is large, and since the RSSI value measured by the second AP device for the first AP device also changes correspondingly during the adjustment of the transmission power of the first AP device, the RSSI value measured by the second AP device for the first AP device can be reduced to the first RSSI threshold value T _ RSSI _ CONNECTION by reducing the transmission power of the first AP device, so that the second AP device and the first AP device can just maintain stable communication CONNECTION. In addition, when the RSSI value of the first AP device measured by the second AP device is lower than the first RSSI threshold value T _ RSSI _ CONNECTION, that is, the requirement for maintaining stable communication CONNECTION between the second AP device and the first AP device cannot be met, it indicates that the signal strength of the area where the second AP device is located is weak, and the signal coverage of the first AP device needs to be enhanced to maintain CONNECTION. Therefore, the embodiment of the invention can adaptively adjust the transmission power of the first AP device according to the RSSI value of the first AP device received by the second AP device and the preset first RSSI threshold value T _ RSSI _ CONNECTION, thereby not only reducing the energy consumption of the first AP device, but also ensuring stable communication CONNECTION between the first AP device and the second AP device.

It should be noted that, regarding the RSSI value, since in an actual situation, the second AP device may measure the RSSI value of the first AP device at each time and there may be a change, in the embodiment of the present invention, an average value of all RSSI values of a time period may be taken as the RSSI value, that is, the RSSI value may be an average value of a plurality of RSSI values received by the second AP device in a preset time period by the first AP device.

It should be noted that the Mesh message sent by the second AP device and received by the first AP device includes the RSSI value, where the RSSI value is used to determine the signal strength of the first AP device measured at the current location by the second AP device, and the first AP device adjusts its own transmission power according to the signal strength.

In addition, referring to fig. 5, in an embodiment, the number of the second AP devices is multiple, and each second AP device corresponds to one RSSI value; regarding the above step S200 of adjusting the current transmission power according to the RSSI value to adjust the RSSI value to the preset first RSSI threshold value, the method includes, but is not limited to, the step S300.

Step S300, adjusting the current transmission power according to the minimum value of the RSSI values, so as to adjust the minimum value of the RSSI values to a preset first RSSI threshold value.

In an embodiment, when the first AP device is wirelessly connected to multiple second AP devices at the same time, the embodiment of the present invention may enable the multiple second AP devices to receive the minimum RSSI value among the RSSI values of the first AP device by adjusting the transmission power of the first AP device to be equal to the first RSSI threshold value T _ RSSI _ CONNECTION, so as to ensure that the RSSI values of the first AP devices received by all the currently connected second AP devices all satisfy the first RSSI threshold value T _ RSSI _ CONNECTION.

As shown in fig. 6 and 7, fig. 6 is a schematic view of a scenario in which a first AP device and a third AP device are in a wired connection, and fig. 7 is a flowchart of a power adjustment method according to an embodiment of the present invention, which may be applied to the first AP device in fig. 6, including but not limited to step S400 and step S500.

Step S400, obtaining the RSSI value of the first AP device received by the third AP device;

step S500, adjusting the current transmission power according to the RSSI value so as to adjust the RSSI value to a preset second RSSI threshold value; wherein the second RSSI threshold value represents a received signal quality threshold at the edge of the signal coverage area of the first AP device.

In an embodiment, the first AP device and the third AP device are connected in a wired manner, and the RSSI value received by the third AP device from the first AP device may reflect the strength of the wireless signal currently received by the first AP device. Since the first AP device and the third AP device are in wired connection, it is only necessary to ensure that other WLAN devices, such as an STA, can maintain communication connection in an area between the first AP device and the third AP device, and therefore, when the first AP device transmits with current transmission power, when the RSSI value measured by the third AP device of the first AP device is higher than the second RSSI threshold value T _ RSSI _ EDGE, that is, when the third AP device is located within the current signal coverage area EDGE of the first AP device, it indicates that the current transmission power of the first AP device is higher, and therefore, in the embodiment of the present invention, the RSSI value measured by the third AP device of the third AP device is reduced to the second threshold value RSSI T _ RSSI _ EDGE by reducing the transmission power of the first AP device, which is equivalent to that the third AP device is located just at the signal coverage area EDGE of the first AP device. In addition, when the RSSI value measured by the third AP device of the first AP device is lower than the second RSSI threshold value T _ RSSI _ EDGE, that is, the third AP device is located outside the EDGE of the current signal coverage area of the first AP device, it indicates that the current transmission power of the first AP device is low, which may cause that other WLAN devices cannot be in communication connection in the area between the first AP device and the third AP device. Therefore, the embodiment of the present invention can adaptively adjust the transmission power of the first AP device according to the RSSI value of the first AP device received by the third AP device and the preset second RSSI threshold value T _ RSSI _ EDGE, which not only can reduce the energy consumption of the first AP device, but also can ensure that other WLAN devices can maintain communication connection in the area between the first AP device and the third AP device.

It is noted that the second RSSI threshold value T _ RSSI _ EDGE is a received RSSI threshold value of the coverage EDGE of the first AP device. In general, the second RSSI threshold value T _ RSSI _ EDGE is smaller than the first RSSI threshold value T _ RSSI _ CONNECTION, so that the transmission power of the first AP device can be reduced to be lower in the case of wired CONNECTION, which is more energy-saving.

In addition, it is to be noted that, regarding the RSSI value, in an actual situation, since there may be a change in the RSSI value measured by the third AP device at each time by the first AP device, the embodiment of the present invention may take an average value of all RSSI values of a time period as the RSSI value, that is, the RSSI value may be an average value of a plurality of RSSI values received by the third AP device within a preset time period.

It should be noted that the Mesh message sent by the third AP device and received by the first AP device includes the RSSI value, where the RSSI value is used to determine the signal strength of the first AP device measured at the current location by the third AP device, and the first AP device adjusts its own transmission power according to the signal strength.

It is understood that, regarding the wired connection manner between the first AP device and the third AP device, the connection manner may include a connection manner of a wired interface such as ethernet, USB (Universal Serial Bus), or power line.

In addition, referring to fig. 8, in an embodiment, the number of the third AP devices is multiple, and each third AP device corresponds to one RSSI value; regarding the above step S500 of adjusting the current transmission power according to the RSSI value to adjust the RSSI value to the preset second RSSI threshold value, the method includes, but is not limited to, the step S600.

Step S600, adjusting the current transmission power according to the minimum value of the RSSI values, so as to adjust the minimum value of the RSSI values to a preset second RSSI threshold value.

In an embodiment, when the first AP device is wirelessly connected to multiple third AP devices at the same time, the embodiment of the present invention may enable a minimum value of RSSI values of the multiple third AP devices receiving the first AP device to be equal to the second RSSI threshold value T _ RSSI _ EDGE by adjusting the transmission power of the first AP device, so as to ensure that the RSSI values of all the currently connected third AP devices receiving the first AP device all satisfy the second RSSI threshold value T _ RSSI _ EDGE.

Step S700, obtaining RSSI values of the first AP device received by the second AP device and the third AP device;

step S800, adjusting the current transmission power according to the RSSI value, so as to adjust the RSSI value of the first AP device received by the second AP device to be a preset first RSSI threshold value, and adjust the RSSI value of the first AP device received by the third AP device to be greater than or equal to a preset second RSSI threshold value; wherein the first RSSI threshold value represents a received signal quality threshold of the second AP device; the second RSSI threshold value represents a received signal quality threshold at the edge of the signal coverage area of the first AP device.

In an embodiment, since in an actual situation, the distance between each of the second AP device and the third AP device and the first AP device may affect the adjustment of the transmission power of the first AP device, when a difference between a distance value between the second AP device and the first AP device and a distance value between the third AP device and the first AP device is greater than a certain value, where the value is usually a negative number, the second AP device and the first AP device may be just kept in a stable communication connection state by adjusting the transmission power of the first AP device, and the third AP device may be located at an edge or in an area of a signal coverage area of the first AP device under the condition that the second AP device and the first AP device are just kept in the stable communication connection state.

Therefore, the embodiment of the present invention can adaptively adjust the transmission power of the first AP device according to the RSSI value of the first AP device and the preset first RSSI threshold value received by the second AP device, and according to the RSSI value of the first AP device and the preset second RSSI threshold value received by the third AP device, thereby not only reducing the energy consumption of the first AP device as much as possible, but also ensuring stable communication connection between the first AP device and the second AP device and ensuring that other WLAN devices such as STAs can maintain communication connection in the area between the first AP device and the third AP device.
