Detailed Description
in the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
in order to explain the technical means of the present invention, the following description will be given by way of specific examples.
referring to fig. 1, a schematic flowchart of a method for wireless roaming according to an embodiment of the present invention is shown, where the method is applied to a wireless device, the wireless device provides at least two frequency bands, service set identifiers of the at least two frequency bands are the same, and the wireless device is a wireless router or a wireless access point, and as shown in the drawing, the method may include the following steps:
step S101, under the condition that the wireless terminal is associated to the first frequency band of the wireless device, the wireless device monitors the network condition of the wireless terminal in real time.
in embodiments of the present invention, a wireless device may provide two or more frequency bands. In the embodiment of the present invention, two frequency bands are taken as an example for description, and the two frequency bands provided by the wireless device are a 2.4G frequency band and a 5G frequency band, respectively.
the wireless device may monitor the network condition of the wireless terminal in real time, in the event that the wireless terminal has been associated to the first frequency band of the wireless device.
specifically, if the first frequency band is a frequency band with an available bandwidth greater than a preset bandwidth threshold, the wireless device monitors the signal intensity of the first frequency band or the communication rate of the first frequency band in real time; and if the first frequency band is a frequency band with the available bandwidth smaller than a preset bandwidth threshold, the wireless equipment monitors the signal intensity of the first frequency band in real time.
The preset bandwidth threshold may be set to 40MHz, the 5G frequency band is a frequency band in which the available bandwidth is greater than the preset bandwidth threshold, and the 2.4G frequency band is a frequency band in which the available bandwidth is less than the preset bandwidth threshold.
In a better area of the network, the communication rate of the 5G frequency band is generally higher than that of the 2.4G frequency band, so that the communication rate of the 2.4G frequency band is not monitored when the network condition of the wireless terminal is monitored.
Step S102, the wireless device roams the wireless terminal to a second frequency band or controls the wireless terminal not to roam according to the change situation of the network condition, wherein the first frequency band and the second frequency band are two different frequency bands of the at least two frequency bands.
In the embodiment of the present invention, if the first frequency band is a frequency band whose available bandwidth is greater than a preset bandwidth threshold, and the second frequency band is a frequency band whose available bandwidth is less than a preset bandwidth threshold, if the signal strength value of the first frequency band is less than a first strength threshold or the communication rate value of the first frequency band is less than a first rate threshold, the wireless terminal is roamed to the second frequency band, and if the signal strength value of the first frequency band is greater than a second strength threshold and the communication rate value of the first frequency band is greater than a second rate threshold, the wireless terminal is controlled not to roam.
If the first frequency band is a frequency band with the available bandwidth smaller than a preset bandwidth threshold value, the second frequency band is a frequency band with the available bandwidth larger than the preset bandwidth threshold value, if the signal intensity value of the first frequency band is larger than a third intensity threshold value, the wireless terminal is roamed to the second frequency band, and if the signal intensity value of the first frequency band is smaller than a fourth intensity threshold value, the wireless terminal is controlled not to roam;
Wherein the second intensity threshold is greater than the first intensity threshold, the third intensity threshold is greater than the fourth intensity threshold, and the second rate threshold is greater than the first rate threshold.
It can be seen that for the first frequency band, the threshold of the signal strength includes a first strength threshold and a second strength threshold, and the threshold of the communication rate includes a first rate threshold and a second rate threshold. Wherein the second intensity threshold is greater than the first intensity threshold, and the second rate threshold is greater than the first rate threshold. When the signal intensity is changed from good to bad, judging by using a low threshold value, namely a first intensity threshold value or a first speed threshold value; when the signal strength is improved from the difference, the determination is performed using a high threshold, that is, the second strength threshold or the second rate threshold. By this arrangement, a high-low threshold mechanism is implemented, so that repeated triggering of thresholds due to network fluctuations can be avoided.
examples are as follows: if the wireless device supports a 2.4G frequency band and a 5G frequency band, if the first frequency band is 5G, the second frequency band is 2.4G, and if the first frequency band is 2.4G, the second frequency band is 5G.
since the attenuation speeds of the 2.4G and 5G frequency band signals in the space are different, the two frequency bands are judged by adopting different signal strength thresholds. Additionally, the signal strength threshold and the rate threshold may be adjusted with the performance specifications and typical usage scenarios of the wireless device.
If the wireless terminal is associated to the 2.4G frequency band, the signal intensity is considered, if the signal intensity value of the wireless terminal changes from a better network area to a value lower than 20dB, the network condition is considered to be poor, and the wireless terminal can be controlled not to roam; if the signal intensity value of the wireless terminal is changed to be higher than 30dB from a poor network area, the network signal is considered to be good, and the wireless terminal can be controlled to roam to a 5G frequency band. I.e. the threshold is "30 dB-20 dB", i.e. the third intensity threshold is 30dB and the fourth intensity threshold is 20 dB.
If the wireless terminal is associated with the 5G frequency band, and for the 5G frequency band, the signal intensity is considered, and if the change from the better area of the network is lower than 10dB, the network condition is considered to be poor; if the change from the poor area of the network is higher than 20dB, the network signal is considered to be good, namely the threshold value is 20dB-10dB, namely the first intensity threshold value is 10dB, and the second intensity threshold value is 20 dB;
in addition, for the 5G frequency band, the communication rate needs to be considered, and if the change from the better area of the network is lower than 10Mbps, the network condition is considered to be poor; if the change is higher than 30Mbps from a poor area of the network, the network signal is considered to be good, that is, the threshold is "30 Mbps-10 Mbps", that is, the first rate threshold is 10Mbps, and the second rate threshold is 30 Mbps.
therefore, if the wireless terminal is already associated with the 5G frequency band, if the signal strength value of the 5G frequency band is less than 10dB or the communication rate value of the 5G frequency band is less than 10Mbps, it is considered that the network signal is degraded, and the wireless terminal can roam to the 2.4G frequency band, and if the signal strength value of the 5G frequency band is greater than 20dB and the communication rate value of the 5G frequency band is greater than 30Mbps, it is considered that the network signal is good, and the wireless terminal is controlled not to roam.
for a region with a better network, the communication rate of the 5G band is always higher than that of the 2G band, so the communication rate of the 2.4G band is not considered.
In practical application, if the wireless terminal is in a 5G frequency band and the signal becomes poor, the wireless terminal is required to roam to 2.4G, otherwise, the wireless terminal is not roaming; if the signal is good in the 2.4G frequency band, the wireless terminal should be roamed to 5G, otherwise, the wireless terminal does not roam.
specifically, the wireless device monitors the signal strength of the first frequency band or the communication rate of the first frequency band in real time through the following two steps:
Step 1, a wireless device sends a Beacon Report request (BR) frame to a wireless terminal, and requests the wireless terminal to send a signal intensity value of a first frequency band or a communication speed value of the first frequency band;
and step 2, the wireless equipment receives the signal intensity value of the first frequency band or the communication speed value of the first frequency band sent by the wireless terminal.
specifically, during roaming, the wireless device first sends a BR frame to the wireless terminal, and requests the wireless terminal to evaluate and report a signal strength value of the first frequency band or a communication rate value of the first frequency band. After waiting a preset time, such as three seconds, the wireless device abandons the evaluation of the Beacon Report if no reply is received from the wireless terminal.
Specifically, the wireless device sends a Basic Service Set transfer Management (BTM) frame to the wireless terminal, and roams the wireless terminal to the second frequency band, and the whole process is automatically completed without configuration and action by a user of the wireless terminal or an administrator of the wireless device.
Preferably, after the wireless device roams the wireless terminal to the second frequency band, the wireless device may further control itself not to roam the wireless terminal to a third frequency band within a preset time, where the third frequency band is one of the at least two frequency bands different from the second frequency band. Specifically, the preset time may be set to 1 minute.
The wireless device of the embodiment of the invention provides at least two frequency bands, the service set identifications of the at least two frequency bands are the same, under the condition that the wireless terminal is associated to the first frequency band of the wireless device, the wireless device can monitor the network condition of the wireless terminal in real time, and roam the wireless terminal to the second frequency band according to the change condition of the network condition, thereby realizing the switching of the access frequency bands of the wireless terminal. The wireless roaming process is totally dominated by wireless equipment, compared with a wireless roaming mode dominated by a wireless terminal, the problems of easy disconnection, reaction lag, incapability of dynamically adapting to a wireless environment and the like do not exist, and the automatic roaming can be realized without additional actions of a user of the wireless terminal or an administrator of the wireless equipment, so that the user experience is greatly improved.
in addition, when roaming is realized, the signal strength threshold and the rate threshold are set through a high-low threshold mechanism, and repeated triggering of the threshold due to network fluctuation can be effectively avoided.
in addition, when the roaming is realized, the wireless terminal is selected to roam to the 5G frequency band when the signal strength of the 2.4G frequency band is good, and the wireless terminal is selected to roam to the 2.4G frequency band when the signal strength or the communication rate of the 5G frequency band is weak, so that the propagation characteristic of the radio is fully considered, and the wireless terminal is more suitable for the actual use condition of a wireless network.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
