Embodiment
In describing below, in order to illustrate rather than in order to limit, it is proposed that such as tool of particular system structure, technology etc
Body details, thoroughly to understand the embodiment of the present invention.However, it will be clear to one skilled in the art that there is no these specific
The present invention can also be realized in the other embodiments of details.In other situations, omit to well-known system, device, electricity
Road and the detailed description of method, in case unnecessary details hinders description of the invention.
In order to illustrate technical solutions according to the invention, illustrated below by specific embodiment.
It is the schematic flow diagram of the method for the radio roaming that the embodiment of the present invention one is provided referring to Fig. 1, this method is applied to
Wireless device, the wireless device provides at least two frequency ranges, and the service set of at least two frequency range is identical, the nothing
Line equipment is wireless router or WAP, and this method may comprise steps of as shown in the figure：
Step S101, in the case of the first frequency range that wireless terminal has been associated to wireless device, wireless device is real-time
Monitor the network condition of wireless terminal.
In embodiments of the present invention, wireless device can provide two or more frequency range.The embodiment of the present invention
In, illustrated by taking two frequency ranges as an example, two frequency ranges that wireless device is provided are 2.4G frequency ranges and 5G frequency ranges respectively.
In the case of the first frequency range that wireless terminal has been associated to wireless device, wireless device can monitor nothing in real time
The network condition of line terminal.
If specifically, first frequency range is the frequency range that available bandwidth is more than pre-set bandwidths threshold value, wireless device is real-time
Monitor the signal intensity of the first frequency range or the communication speed of the first frequency range；If first frequency range is available bandwidth less than default
The signal intensity of the frequency range of bandwidth threshold, then the first frequency range of the real-time monitoring of wireless device.
Wherein, pre-set bandwidths threshold value could be arranged to 40MHz, and 5G frequency ranges are the frequencies that available bandwidth is more than pre-set bandwidths threshold value
Section, 2.4G frequency ranges are the frequency ranges that available bandwidth is less than pre-set bandwidths threshold value.
Due to the preferable region of network, the communication speed of 5G frequency ranges is general higher than the communication speed of 2.4G frequency range, therefore,
When monitoring the network condition of wireless terminal, the communication speed of 2.4G frequency ranges is not monitored.
Step S102, wireless device according to the situation of change of the network condition by wireless terminal roaming to the second frequency range or
Person controls wireless terminal without roaming, and first frequency range and the second frequency range are two at least two frequency range different
Frequency range.
In embodiments of the present invention, if the first frequency range is the frequency range that available bandwidth is more than pre-set bandwidths threshold value, the second frequency range
Be available bandwidth be less than pre-set bandwidths threshold value frequency range, if the signal strength values of the first frequency range be less than the first intensity threshold or
The communication speed value of first frequency range is less than first rate threshold value, then by wireless terminal roaming to the second frequency range, if the first frequency range
Signal strength values be more than the communication speed value of the second intensity threshold and the first frequency range and be more than the second rate-valve value, then control wireless
Terminal is without roaming.
If the first frequency range is the frequency range that available bandwidth is less than pre-set bandwidths threshold value, the second frequency range is available bandwidth more than default
The frequency range of bandwidth threshold, if the signal strength values of the first frequency range are more than the 3rd intensity threshold, by wireless terminal roaming to second
Frequency range, if the signal strength values of the first frequency range are less than the 4th intensity threshold, control wireless terminal is without roaming；
Wherein, second intensity threshold is more than first intensity threshold, and the 3rd intensity threshold is more than described the
Four intensity thresholds, second rate-valve value is more than the first rate threshold value.
As can be seen that for the first frequency range, the threshold value of signal intensity includes the first intensity threshold and the second intensity threshold, led to
Interrogating the threshold value of speed includes first rate threshold value and the second rate-valve value.Wherein, the second intensity threshold is more than the first intensity threshold,
Second rate-valve value is more than first rate threshold value.Wherein, using Low threshold, that is, it is exactly the last the first when signal intensity is by being deteriorated well
Degree threshold value or first rate threshold value are judged；Using high threshold, that is, it is exactly the second intensity threshold when signal intensity is improved by difference
Value or the second rate-valve value are judged.By this set, high-low threshold value mechanism is realized, so as to avoid because of network
Fluctuation and activation threshold value repeatedly.
It is exemplified below：If what wireless device was supported is 2.4G frequency ranges and 5G frequency ranges, if the first frequency range is 5G, the second frequency range
It is 2.4G, if the first frequency range is 2.4G frequency ranges, the second frequency range is 5G frequency ranges.
Because 2.4G and 5G the frequency band signals rate of decay in space are different, so two frequency ranges use different letters
Number intensity threshold is judged.In addition, signal strength threshold and rate-valve value can be with the specifications and allusion quotation of wireless device
Type usage scenario is adjusted.
If wireless terminal has been associated to 2.4G frequency ranges, signal intensity is investigated, if the signal strength values of wireless terminal are from net
The preferable regional change of network is less than 20dB, then it is assumed that network condition is deteriorated, and can control wireless terminal without roaming；If nothing
The signal strength values of line terminal are from the poor regional change of network for higher than 30dB, then it is assumed that network signal improves, and can control
Wireless terminal roaming is to 5G frequency ranges.I.e. threshold value is " 30dB-20dB ", that is to say, that the 3rd intensity threshold is 30dB, the 4th intensity
Threshold value is 20dB.
If wireless terminal has been associated to 5G frequency ranges, for 5G frequency ranges, signal intensity is investigated, if from the preferable region of network
Change is turned to less than 10dB, then it is assumed that network condition is deteriorated；If being higher than 20dB from the poor regional change of network, then it is assumed that network
Signal improves, i.e., threshold value is " 20dB-10dB ", that is to say, that the first intensity threshold is 10dB, and the second intensity threshold is 20dB；
In addition, for 5G frequency ranges, in addition it is also necessary to investigate communication speed, if from the preferable regional change of network be less than
10Mbps, then it is assumed that network condition is deteriorated；If being higher than 30Mbps from the poor regional change of network, then it is assumed that network signal becomes
Good, i.e., threshold value is that " 30Mbps-10Mbps " that is first rate threshold value is 10Mbps, and the second rate-valve value is 30Mbps.
So, if wireless terminal has been associated to 5G frequency ranges, if the signal strength values of 5G frequency ranges are less than 10dB or 5G
The communication speed value of frequency range is less than 10Mbps, then it is assumed that network signal is deteriorated, can be by wireless terminal roaming to 2.4G frequency ranges, such as
The communication speed value that the signal strength values of fruit 5G frequency ranges are more than 20dB and 5G frequency ranges is more than 30Mbps, then it is assumed that network signal becomes
Good, control wireless terminal is without roaming.
For, the preferable region of network, the communication speed of the communication speeds of 5G frequency ranges always than 2G frequency range is high, so not examining
Examine the communication speed of 2.4G frequency ranges.
During practical application, if wireless terminal is in 5G frequency ranges and signal and is deteriorated, should by the wireless terminal roaming to 2.4G,
Otherwise wireless terminal is without roaming；In 2.4G frequency ranges, signal improves, then should by the wireless terminal roaming to 5G, otherwise without
Line terminal is without roaming.
Specifically, wireless device monitors the signal intensity or the first frequency range of the first frequency range by following two steps in real time
Communication speed：
Step 1, wireless device send beacon report request (BR, Beacon Report) frame to wireless terminal, and request is wireless
Terminal sends the signal strength values of the first frequency range or the communication speed value of the first frequency range；
Step 2, wireless device receive the signal strength values for the first frequency range that wireless terminal is sent or leading to for the first frequency range
Interrogate rate value.
Specifically, during roaming, wireless device first sends BR frames to wireless terminal, and request wireless terminal is assessed and reports first
The communication speed value of the signal strength values of frequency range or the first frequency range.Wireless device waits preset time, such as after three seconds, if
The reply of wireless terminal is not received, then abandons assessing Beacon Report.
Specifically, wireless device sends basic service set transfer management request (Basic Service Set to wireless terminal
Transition Management, BTM) frame, by wireless terminal roaming to the second frequency range, whole process is automatically performed, nothing
The user of wireless terminal or the keeper of wireless device is needed to be configured and acted.
Preferably, after wireless device is by wireless terminal roaming to the second frequency range, wireless device can also control itself
Can not be by wireless terminal roaming to the 3rd frequency range in preset time, the 3rd frequency range is difference at least two frequency range
In a frequency range of the second frequency range.Specifically, it is 1 minute that can set the preset time.
The wireless device of the embodiment of the present invention provides at least two frequency ranges, the service set phase of at least two frequency range
Together, in the case of the first frequency range that wireless terminal has been associated to wireless device, wireless device can be whole with real time monitoring wireless
The network condition at end, and according to the situation of change of the network condition by wireless terminal roaming to the second frequency range, realize wireless
Terminal accesses the switching of frequency range.The process of radio roaming, is all dominated by wireless device, compared to by wireless terminal dominate it is wireless
Roaming mode, in the absence of easy broken string, response lag, can not dynamically adapting wireless environment the problems such as, it is not required that wireless terminal
User or wireless device keeper implement additional act, it is possible to achieve automatic roaming, greatly improve Consumer's Experience.
In addition, when realizing roaming, can be effective by high-low threshold value mechanism setting signal intensity threshold and rate-valve value
Avoid because of network fluctuation activation threshold value repeatedly.
In addition, when realizing roaming, selected when 2.4G frequency band signals intensity improves by wireless terminal roaming to 5G frequency ranges,
When the signal intensity or communication speed of 5G frequency ranges die down, selection roams into 2.4G frequency ranges, has adequately taken into account radio
Propagation characteristic, the actual service condition of wireless network of more fitting.
It should be understood that the size of the sequence number of each step is not meant to the priority of execution sequence, each process in above-described embodiment
Execution sequence should determine that the implementation process without tackling the embodiment of the present invention constitutes any limit with its function and internal logic
It is fixed.
