Technical Field

Background

There are two main types of devices in WLAN networks: one is an Access Point (AP), and the other is a wireless terminal device (STA) (e.g., a computer, a mobile phone, a pad, and other terminal devices with WLAN function).

In the related art, most APs and STAs support both 2.4G and 5G bands. Since the 2.4G band has a low rate and large interference, and the 5G band has a high rate and small interference, the AP recommends the 5G band for the STA under normal conditions. However, in some cases, for example, the load of the 5G band is too high, or the load of the 2.4G band is low or the signal is weak, the 2.4G band can provide better internet experience due to low speed and high transmission success rate.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a flow chart illustrating a method for determining an associated frequency band according to an exemplary embodiment; the embodiment may be applied to a wireless local area network, and the execution subject of the embodiment may be an access point AP in the wireless local area network, as shown in fig. 1, the method includes the following steps S11-S13:

in step S11, the media access control MAC address of the terminal device is determined.

In an embodiment, the wireless access point AP determines the MAC address of the terminal device STA in a preset manner.

The MAC (Media Access Control) address is translated into a Media Access Control, or a physical address or a hardware address, which is used to define the location of the network device. In the OSI model, a third layer network layer is responsible for IP addresses and a second layer data link layer is responsible for MAC addresses. Thus, a STA will have a MAC address and each network location will have an IP address specific to it.

In an embodiment, the preset manner for determining the MAC address may refer to the embodiments shown in fig. 6 and fig. 7, which will not be described in detail herein.

In step S12, the device information corresponding to the MAC address is determined by inquiring the correspondence between the MAC address and the device information stored in advance.

In an embodiment, after determining the MAC address of the STA, the AP may determine the device information of the STA according to a correspondence between each locally stored MAC address and the device information.

In an embodiment, the device information may include association capability information of each frequency band that the STA has, signal strength of each frequency band of the STA, and the like.

In step S13, the associated frequency band of the terminal device is determined according to the device information.

In an embodiment, after determining the device information of the STA, the AP may determine the associated frequency band of the STA according to the device information.

In an embodiment, the AP may recommend the determined associated frequency band to the STA for association before associating with the STA; alternatively, the AP may adjust the frequency band currently associated with the STA based on the determined associated frequency band after associating with the STA.

As can be seen from the foregoing embodiments, in the embodiments of the present disclosure, by determining a media access control MAC address of a terminal device, and by querying a correspondence between a pre-stored MAC address and device information, determining device information corresponding to the MAC address, and then determining an associated frequency band of the terminal device according to the device information, it is possible to determine the associated frequency band of the terminal device according to the pre-stored device information, and because the device information is considered in determining the associated frequency band, intelligence of an associated frequency band determination scheme can be improved, and thus information transmission success rate is improved, and user experience on internet is improved.

Fig. 2 is a flow chart illustrating a method of associated frequency band determination according to yet another exemplary embodiment; the embodiment may be applied to a wireless local area network, and the execution subject of the embodiment may be an access point AP in the wireless local area network, as shown in fig. 2, the method includes the following steps S21-S26:

in step S21, a detection message sent by the terminal device for detecting the wireless local area network is received.

In an embodiment, the detection message may be a Probe Request frame.

In an embodiment, when the STA accesses a Wireless Local Area Network (WLAN) through an active scanning mode, the AP receives a Probe Request frame sent by the STA.

In an embodiment, the AP may receive Probe Request frames transmitted by the STA in one or more frequency bands.

In step S21, the MAC address and the device information of the terminal device are determined according to the detection packet.

In an embodiment, the AP may determine the MAC address of the terminal device and corresponding device information through the received Probe Request frame.

In an embodiment, if the AP receives the Probe Request frame, the MAC address of the STA carried in the message may be determined.

In an embodiment, the device information includes frequency band association capability, signal strength information, and the like. For example, if the AP can receive the Probe Request frame of the STA in the 5G band, it indicates that the STA has the 5G band capability; similarly, if the AP can receive the Probe Request frame of the STA in the 2.4G band, it indicates that the STA has the 2.4G band capability.

In an embodiment, the AP may determine the signal strength of the STA that transmits the Probe Request frame based on a built-in chip.

In step S23, it is determined whether the correspondence between the MAC address and the device information has been stored locally.

In an embodiment, the STA may determine a correspondence between the MAC address of the STA and the device information according to the Probe Request frame.

For example, the STA may store a corresponding table, and each entry of the table may include a MAC address of the STA, 2.4G signal strength RSSI _ G, 2.4G Band capability Band _ G, 5G signal strength RSSI _ a, and 5G Band capability Band _ a.

In step S24, if it is determined that the correspondence between the MAC address and the device information is not locally stored, the correspondence is stored.

In an embodiment, after determining a correspondence between an MAC address and device information according to a received Probe Request frame of a 2.4G Band, the AP queries the correspondence table, and if the entry does not exist (for example, signal strength information and Band capability information corresponding to the MAC do not exist), a new entry is created and the MAC address, the 2.4G signal strength RSSI _ G, and the 2.4G Band capability Band _ G are filled; similarly, after determining the corresponding relationship between the MAC address and the device information according to the received Probe Request frame of the 5G frequency Band, the AP queries the corresponding relationship table, and if the table does not exist, a new table is created and the MAC address, the 5G signal strength RSSI _ a, and the 5G frequency Band capability Band _ a are filled.

In step S25, if it is determined that the correspondence between the MAC address and the device information has been locally stored, the correspondence stored locally is updated.

In an embodiment, after determining a correspondence between an MAC address and device information according to a received Probe Request frame of a 2.4G frequency Band, the AP queries the correspondence table, and if there is the entry (for example, there is signal strength information and frequency Band capability information corresponding to the MAC), updates the entry, for example, updates 2.4G signal strength RSSI _ G and 2.4G frequency Band capability Band _ G in the entry; similarly, after determining the correspondence between the MAC address and the device information according to the received Probe Request frame of the 5G Band, the AP queries the correspondence table, and if the entry exists, updates the entry, for example, updates the 5G signal strength RSSI _ a and the 2.4G Band capability Band _ a in the entry.

In step S26, the media access control MAC address of the terminal device is determined.

In step S27, the device information corresponding to the MAC address is determined by inquiring the correspondence between the MAC address and the device information stored in advance.

In step S28, the associated frequency band of the terminal device is determined according to the device information.

The steps S26-S28 are the same as the steps S11-S13 in the embodiment shown in fig. 1, and are not repeated herein.

As can be seen from the foregoing embodiments, in the embodiments of the present disclosure, by receiving a detection message sent by a terminal device and used for detecting a wireless local area network, and determining an MAC address and device information of the terminal device according to the detection message, when it is determined that a correspondence between the MAC address and the device information is not locally stored, the correspondence is stored, and when it is determined that a correspondence between the MAC address and the device information is locally stored, the correspondence is updated, so that it is possible to subsequently determine device information of the terminal device based on the correspondence, and further determine an associated frequency band according to the device information, which can improve intelligence of an associated frequency band determination scheme, improve a success rate of information transmission, and improve user experience on internet.

Fig. 3 is a flow chart illustrating a method of associated frequency band determination in accordance with yet another exemplary embodiment; the embodiment may be applied to a wireless local area network, and the execution subject of the embodiment may be an access point AP in the wireless local area network, as shown in fig. 3, the method includes the following steps S31-S36:

in step S31, the media access control MAC address of the terminal device is determined.

In step S32, the device information corresponding to the MAC address is determined by inquiring the correspondence between the MAC address and the device information stored in advance.

The steps S31-S32 are the same as the steps S11-S12 in the embodiment shown in fig. 1, and are not repeated herein.

In step S33, determining whether the terminal device has only the association capability of the first frequency band; if yes, go to step S34; if not, go to step S35;

in an embodiment, the AP may determine association capabilities of all frequency bands possessed by the STA to determine whether the STA possesses only the association capabilities of the current frequency band (i.e., the first frequency band).

For example, if the current AP receives a Probe Request frame of the STA in a first frequency band (e.g., 2.4G frequency band), and determines the MAC address of the STA based on the Probe Request frame, the corresponding relationship between the MAC and the device information stored in advance may be queried to determine the association capability of all frequency bands possessed by the STA. If the AP determines that the association capability of the 5G band does not exist in the pre-stored correspondence, it may determine that the STA only has the association capability of the 2.4G band, and determine that the STA only has the association capability of the first band.

In step S34, the first frequency band is determined as the associated frequency band of the terminal device.

In an embodiment, if the AP determines that the STA has only the association capability of the first frequency band, the AP may determine the first frequency band as the association frequency band of the STA.

In step S35, determining whether the signal strength of the second frequency band exceeds a preset strength threshold; if yes, go to step S36; if not, step S34 is executed.

In an embodiment, if the current AP receives a Probe Request frame of the STA in a first frequency band (e.g., a 2.4G frequency band), and determines the MAC address of the STA based on the Probe Request frame, the current AP may query a correspondence between a MAC stored in advance and device information to determine the association capability of all frequency bands possessed by the STA. If the AP determines that the association capability of the second frequency band (for example, the 5G frequency band) exists in the pre-stored correspondence, it may be determined that the STA has the association capability of the second frequency band.

In an embodiment, after determining that the STA has the association capability of the second frequency band, it may be further determined whether the signal strength of the second frequency band exceeds a preset strength threshold.

For example, a preset strength threshold may be preset, and after it is determined that the STA has the association capability of the second frequency band, the signal strength of the second frequency band is compared with the preset strength threshold to determine whether the signal strength of the second frequency band exceeds the preset strength threshold.

It should be noted that, reference may be made to related technologies for determining the signal strength of the second frequency band, and this embodiment does not limit this.

In step S36, the second frequency band is determined as the associated frequency band of the terminal device.

In an embodiment, when it is determined that the signal strength of the second frequency band exceeds a preset strength threshold, the second frequency band may be determined as an associated frequency band of the terminal device; and if the signal strength of the second frequency band is determined to be lower than the preset strength threshold, the first frequency band may be determined as the associated frequency band of the terminal device.

It can be known from the foregoing embodiment that, in the embodiment of the present disclosure, by determining whether the terminal device has the association capability of the second frequency band, and when it is determined that the terminal device has the association capability of the second frequency band, determining whether the signal intensity of the second frequency band exceeds the preset intensity threshold, and then when it is determined that the signal intensity of the second frequency band exceeds the preset intensity threshold, determining the second frequency band as the association frequency band of the terminal device, and otherwise, determining the first frequency band as the association frequency band of the terminal device, it is possible to determine the association frequency band of the terminal device according to the signal intensity.

Fig. 4 is a flow chart illustrating a method of associated frequency band determination in accordance with yet another exemplary embodiment; the embodiment may be applied to a wireless local area network, and the execution subject of the embodiment may be an access point AP in the wireless local area network, as shown in fig. 4, the method includes the following steps S41-S48:

in step S41, the media access control MAC address of the terminal device is determined.

In step S42, the device information corresponding to the MAC address is determined by inquiring the correspondence between the MAC address and the device information stored in advance.

In step S43, determining whether the terminal device only has the association capability of the first frequency band, if yes, executing step S44; if not, step S45 is executed.

In step S44, the first frequency band is determined as the associated frequency band of the terminal device.

In step S45, determining whether the signal strength of the second frequency band exceeds a preset strength threshold; if yes, go to step S46; if not, step S44 is executed.

The steps S41-S45 are the same as the steps S31-S35 in the embodiment described in fig. 3, and are not repeated herein.

In step S46, determining whether the current network traffic of the terminal device is smaller than a preset traffic threshold; if yes, go to step S47; otherwise, step S44 is executed.

In an embodiment, when the AP determines that the signal strength of the second frequency band exceeds the preset strength threshold, it may determine the current network traffic of the STA, and compare the network traffic with the preset wave threshold; when it is determined that the network traffic is less than the threshold traffic threshold, performing step S47; if it is determined that the network traffic is greater than or equal to the threshold traffic threshold, step S44 is executed.

It should be noted that, reference may be made to related technologies for determining the network traffic of the terminal device, and this embodiment does not limit this.

In step S47, the second frequency band is determined as the associated frequency band of the terminal device.

As can be seen from the foregoing embodiments, the determining of the associated frequency band of the terminal device according to the signal strength and the network traffic can be implemented by determining whether the terminal device has the associated capability of the second frequency band, determining whether the signal strength of the second frequency band exceeds a preset strength threshold when it is determined that the terminal device has the associated capability of the second frequency band, determining whether the network traffic of the terminal device exceeds a preset traffic threshold when it is determined that the signal strength of the second frequency band exceeds the preset strength threshold, determining the second frequency band as the associated frequency band of the terminal device when it is determined that the network traffic does not exceed the preset traffic threshold, otherwise determining the first frequency band as the associated frequency band of the terminal device, and considering the signal strength of the frequency band and the network traffic of the terminal device in the determining of the associated frequency band, thereby further improving the intelligence of the associated frequency band determining scheme, and then improve information transmission success rate, promote user's experience of surfing the net.

FIG. 5 is a flow diagram illustrating how the MAC address of a terminal device is determined in accordance with an illustrative embodiment; the present embodiment takes how to determine the MAC address of the terminal device as an example on the basis of the above-described embodiments. As shown in fig. 5, the determining the MAC address of the terminal device in the above step S11 may include the following steps S51-S52:

in step S51, before associating with the terminal device, an association request for associating with the wireless local area network sent by the terminal device is received.

In the related art, the association process between the STA and the AP is as follows: the STA first needs to discover a nearby wireless network by scanning, and then sends an inquiry Request Probe Request frame according to the scanning result. The AP should send an Probe Response frame back to the STA. Upon receipt of the Probe Response frame, the STA initiates a link authentication request. And after receiving the association request frame, the AP sends out an association response frame to the STA, so that the whole association process is completed.

In an embodiment, the AP may receive an association request sent by the STA for associating with the wireless local area network before associating with the STA, that is, when the STA does not access the current wireless network.

In step S52, the MAC address of the terminal device is determined according to the association request.

In an embodiment, after the AP receives the association request, the MAC address of the STA may be determined according to the message content of the association request.

As can be seen from the foregoing embodiments, in the embodiments of the present disclosure, before associating with a terminal device, an association request for associating with a wireless local area network sent by the terminal device is received, and a media access control MAC address of the terminal device is determined according to the association request, so that the MAC address of the terminal device can be accurately determined, and a foundation is laid for subsequently querying device information based on the MAC address to determine an associated frequency band of the terminal device.

Fig. 6 is a flow chart illustrating a method of associated frequency band determination in accordance with yet another exemplary embodiment; the embodiment may be applied to a wireless local area network, and the execution subject of the embodiment may be an access point AP in the wireless local area network, as shown in fig. 6, the method includes the following steps S61-S63:

in step S61, after associating with the terminal device, the MAC address of the terminal device is acquired based on a preset period.

In an embodiment, after associating with the STA, that is, when the STA has access to the current wireless network, the AP may acquire the MAC address of the terminal device based on a preset period. For example, the AP may periodically check a pre-stored correspondence table between MAC addresses and device information to obtain the MAC address of the terminal device.

In step S62, the device information corresponding to the MAC address is determined by inquiring the correspondence between the MAC address and the device information stored in advance.

In step S63, the associated frequency band of the terminal device is determined according to the device information.

The steps S62-S63 are the same as the steps S12-S13 in the embodiment shown in fig. 1, and are not repeated herein.

As can be seen from the foregoing embodiments, in the embodiments of the present disclosure, after associating with the terminal device, the media access control MAC address of the terminal device is periodically obtained, which may lay a foundation for subsequently querying device information based on the MAC address to determine an associated frequency band of the terminal device, and further adjust a currently associated frequency band of the terminal device according to the determined associated frequency band, thereby ensuring a success rate of information transmission and improving user experience of surfing the internet.

Fig. 7 is a schematic view of an application scenario of a method for determining an associated frequency band according to an exemplary embodiment; the application scenario involves a wireless access point AP100, a wireless local area network 200, and a terminal device STA 300. As shown in fig. 7, if the wireless access point AP100 receives a Probe Request message sent by the terminal device STA300 in the 2.4G frequency Band, and acquires the MAC address and the device information of the STA300 through the Probe Request message, where the device information includes the signal strength RSSI _ G of the 2.4G frequency Band and the 2.4G frequency Band association capability Band _ G. It should be noted that the AP100 can receive a Probe Request message sent by the STA in the 2.4G frequency Band, which indicates that the STA300 has the frequency Band capability of 2.4G, Band _ G.

Similarly, if the wireless access point AP100 receives the Probe Request message sent by the terminal device STA300 in the 5G frequency Band, and acquires the MAC address and the device information of the STA300 through the Probe Request message, where the device information includes the signal strength RSSI _ G of the 5G frequency Band and the association capability Band _ G of the 5G frequency Band. It should be noted that the AP100 can receive a Probe Request message sent by the STA in the 5G frequency Band, which indicates that the STA300 has the frequency Band capability of 5G, Band _ G.

On this basis, the AP100 may maintain an STA information table of a preset size for recording a correspondence between the MAC address and the device information. Each entry of the STA information table includes a MAC address of the STA, 2.4G signal strength RSSI _ G, 2.4G Band capability Band _ G, 5G signal strength RSSI _ a, and 5G Band capability Band _ a. When the AP100 determines the correspondence between the MAC address and the device information based on the Probe Request message currently received in the 2.4G frequency Band, the STA information table may be queried, and if the information table does not have an entry of the STA (i.e., device information of the 2.4G frequency Band related to the MAC address does not exist), a new entry is created and stored in the MAC address, the 2.4G signal strength RSSI _ G, and the 2.4G frequency Band capability Band _ G; if the entry of the STA exists, the 2.4G signal strength RSSI _ G and the 2.4G Band capability Band _ G of the entry are updated.

Similarly, when the AP100 determines the correspondence between the MAC address and the device information based on the Probe Request message received by the STA entry processing module currently received in the 5G Band, the STA information table may be queried, and if the STA entry does not exist in the information table (i.e., the device information of the 5G Band related to the MAC address does not exist), a new entry is created and stored in the MAC address, the 5G signal strength RSSI _ a, and the 5G Band capability Band _ a; if the entry of the STA exists, the 5G signal strength RSSI _ a and the 5G Band capability Band _ a of the entry are updated.

In an embodiment, if the STA information table is full and there is no new entry, the oldest entry may be aged according to the entry establishment time, that is, the information in the aged STA entry is replaced with the new STA information.

The following takes two cases before the AP associates with the STA and after the AP associates with the STA as examples to describe the association frequency band determination method of the present disclosure, but the present disclosure is not limited thereto.

In the first case: before STA association, if the AP100 receives an association request sent by the STA300 for associating the wireless local area network 200 in a 2.4G frequency band, acquiring an MAC address of the STA300 based on the association request, further traversing the whole prestored STA table entry, inquiring the table entry information of the STA300 according to the MAC address, and further determining whether the STA300 has the association capability of the 5G frequency band based on the table entry information; if the STA300 does not have the 5G capability, the STA300 is directly allowed to associate with the 2.4G frequency band; if 5G band capability is available, further determine the 5G signal strength RSSI _ a of the STA 300. In an embodiment, a threshold of the signal strength may be preset, and if the RSSI _ a is not greater than the threshold, association with the 2.4G frequency band is allowed; if the RSSI _ A is larger than the threshold value, the STA is refused to associate with the 2.4G frequency band, and the STA is recommended to associate with the 5G frequency band.

Similarly, if the AP100 receives an association request for associating with the wireless local area network 200 sent by the STA300 in the 5G frequency band, the AP obtains the MAC address of the STA300 based on the association request, further traverses the whole STA entry stored in advance, queries the entry information of the STA300 according to the MAC address, and further determines whether the STA300 has the association capability of the 2.4G frequency band based on the entry information; if the STA300 does not have the 2.4G capability, the STA300 is directly allowed to associate with the 5G frequency band; if the 2.4G band capability is available, the 2.4G signal strength RSSI _ G of the STA300 is further determined. In an embodiment, a threshold value of the signal strength may be preset, and if the RSSI _ G is not greater than the threshold value, the association of the 5G frequency band is allowed; if the RSSI _ G is larger than the threshold value, the STA is refused to associate with the 5G frequency band, and the STA is recommended to associate with the 2.4G frequency band.

In the second case: after the STA is associated, if the current AP100 and the STA300 are associated in the 2.4G frequency band, the AP100 periodically checks the associated STA300, obtains the MAC address of the STA300, then traverses the whole STA entry stored in advance, queries the entry information of the STA300 according to the MAC address, and further determines whether the STA300 has the 5G capability; if the STA does not have the 5G capability, keeping the state that the STA associates the 2.4G frequency band; if 5G band capability is available, further determine the 5G signal strength RSSI _ a of the STA 300. In an embodiment, a threshold of the signal strength may be preset, and if the RSSI _ a is not greater than the threshold, the STA maintains the state of associating the 2.4G frequency band; in an embodiment, if the RSSI _ a is greater than the threshold value, the current network traffic of the STA may be further determined; in an embodiment, a traffic threshold of the STA300 may be preset, and if the current traffic of the STA300 is not less than the set traffic threshold, the STA maintains the state of associating the 2.4G frequency band; if the current traffic of the STA300 is smaller than the set traffic threshold, the association state between the STA300 and the 2.4G frequency band may be released, the STA re-association may be triggered, a frequency band recommendation procedure may be performed, and the STA300 may be guided to associate to the 5G frequency band.

Similarly, if the current AP100 and the STA300 are associated in the 5G frequency band, the AP100 periodically checks the associated STA300, obtains the MAC address of the STA300, then traverses the whole STA entry stored in advance, queries the entry information of the STA300 according to the MAC address, and further determines whether the STA300 has the 2.4G capability; if the STA does not have the 2.4G capability, the state of the STA associating with the 5G frequency band is maintained; if the 2.4G band capability is available, the 2.4G signal strength RSSI _ G of the STA300 is further determined. In an embodiment, a threshold of the signal strength may be preset, and if the RSSI _ G is not greater than the threshold, the STA keeps the state of associating the 5G frequency band; in an embodiment, if the RSSI _ G is greater than the threshold value, the current network traffic of the STA may be further determined; in an embodiment, a traffic threshold of the STA300 may be preset, and if the current traffic of the STA300 is not less than the set traffic threshold, the STA maintains the state of associating the 5G frequency band; if the current traffic of the STA300 is smaller than the set traffic threshold, the association state between the STA300 and the 5G frequency band may be released, the STA re-association may be triggered, a frequency band recommendation procedure may be performed, and the STA300 may be guided to associate to the 2.4G frequency band.

As can be seen from the above description, in the method for determining an associated frequency band according to the embodiment of the present disclosure, by establishing a table entry for recording STA frequency band capability and signal strength, learning the STA frequency band capability according to a probe request of a receiving STA, performing frequency band recommendation according to the STA frequency band capability and signal strength, and performing frequency band adjustment according to the STA frequency band capability, signal strength, and current flow, an STA having both 5G and 2.4G frequency band capabilities can be guided to associate a 5G frequency band when the signal strength is high, so as to obtain better performance and better user experience; the STA which has the 5G and 2.4G frequency band capabilities can be guided to associate with the 2.4G frequency band when the signal strength is low, so that a better transmission success rate is obtained; other STAs can get better performance.
