Network name identical, login password is identical, such user is without arranging difference for different operating frequency range
Wireless network name, facilitate user to network name and the management of login password.
The embodiment of the present invention specifically may include steps of:
Step 201, when wireless device receives the access request of access terminal, it is judged that described access is eventually
Whether end supports described first working frequency range；
When access terminal needs to connect network, access terminal can send access request to wireless device,
This access request can include the terminal iidentification of access terminal, model etc..
After wireless device receives the access request that access terminal sends, application programming interfaces can be passed through
API inquires about the supported wireless network protocol of access terminal, if the supported wireless network of this access terminal
The wireless network protocol coupling that agreement is corresponding with the first working frequency range, then wireless device can determine that this access is eventually
End supports the first working frequency range.
Step 202, if described access terminal supports described first working frequency range, then detects described access eventually
Hold current signal intensity；
After judging that access terminal supports the first working frequency range, wireless device can call standard further
Wave point, the inquiry current signal intensity of access terminal.
In implementing, the unit of signal intensity can be expressed as dB or dBm, dB and dBm all
Being the unit of power gain, difference is as follows:
DB is a value characterizing relative value, and ratio purely only represents the relative size relation of two amounts,
There is no unit, when consider first power is big compared to the power of second or during little how many dB, the calculating of employing
Formula is: 10log (first power/second power)；If the voltage ratio using both calculates, then the calculating used
Formula is: 20log (first voltage/B plus voltage).Such as, first power is twice than second power, then 10lg (first
Power/second power)=10lg2=3dB.It is to say, the power of first 3dB bigger than the power of second.Otherwise,
If the power of first is the half of the power of second, then the power of first 3dB less than the power of second.
DBm is that a value representing power absolute value is (it is also assumed that be on the basis of 1mW power
Individual ratio), computing formula is: 10log (performance number/1mw).Such as, for the power of 40W, by dBm
Value after unit calculates should be:
10log (40W/1mw)=10log (40000)=10log4+10log10000=46dBm.
It should be noted that the value negative number representation of signal intensity, therefore, the signal intensity ratio of-40dBm
The signal intensity of-50dBm is big.
Step 203, if described current signal intensity is more than the first predetermined threshold value, then accesses described eventually
End accesses to described first working frequency range；
After getting the signal intensity that access terminal is current, determine whether that this current signal intensity is
No it is more than the first predetermined threshold value or less than the second predetermined threshold value, if this current signal intensity is more than first
Predetermined threshold value, then can access to the first working frequency range by access terminal, even if access terminal is operated in
On one working frequency range.
It should be noted that this first predetermined threshold value, the second predetermined threshold value are empirical value, the present invention is real
Execute example the concrete setting of the first predetermined threshold value, the second predetermined threshold value is not restricted, those skilled in the art
Set according to practical situation.
Such as, for double-frequency wireless router, if it detects the letter that access terminal (such as mobile phone) is current
This access terminal more than-40dBm, then can be linked in 5.0GHz frequency range by number intensity.
Step 204, adds the mark of described access terminal in the list of devices pre-build；
After access terminal is linked into the first working frequency range, wireless device can also pre-build on backstage
List of devices adds the mark of this access terminal.Wherein, this list of devices pre-build is for record
Access to the end message of the access terminal of wireless device, so that access terminal to be safeguarded.
Step 205, detects, according to prefixed time interval, the signal intensity that described access terminal is real-time；
It is applied to the embodiment of the present invention, monitoring process can be set, use this monitoring process according to time default
Between be spaced, the signal intensity that this access terminal of periodic detection is real-time.
Step 206, during described access terminal accesses to described first working frequency range, if described
Real-time signal intensity is less than the second predetermined threshold value, then by the frequency range of described access terminal by described first work
The second working frequency range is switched to as frequency range；
In actual applications, if when access terminal is gradually distance from wireless device (when both distances increase),
The monitoring process of wireless device detects that the signal intensity of this access terminal is more and more weak, i.e. signal intensity
Being worth more and more less, when this signal intensity is less than the second predetermined threshold value, then monitoring process can notify wireless
The frequency range of access terminal is switched to the second working frequency range by the first working frequency range by equipment.
It should be noted that the value of above-mentioned second predetermined threshold value can be the value less than the first predetermined threshold value,
Such as, this first predetermined threshold value is-40dBm, and the second predetermined threshold value is-50dBm.If this access terminal
Being gradually distance from wireless router, the real-time signal intensity detected when some moment is less than-50dBm
Time, then access terminal can be automatically switched to 2.4GHz by 5.0GHz frequency range.
Owing to the transmission range of 5GHz only has 35 meters, ability through walls is poor, is only suitable for indoor little scope and covers
Lid and outdoor bridge, when access terminal is gradually distance from wireless device, signal attenuation is relatively big, and same merit
Under rate, the coverage distance of 2.4GHz compares farther out, therefore, when signal attenuation to less than-50dBm time,
Access terminal is automatically switched to 2.4GHz by 5.0GHz frequency range, it is ensured that network stabilization.
Step 207, during described access terminal accesses to described second working frequency range, if detection
To the real-time signal intensity of described access terminal more than the first predetermined threshold value time, by the frequency of described access terminal
Section is switched to described first working frequency range by described second working frequency range.
When access terminal is operated in the second working frequency range, monitoring process continues according to prefixed time interval,
The signal intensity that this access terminal of periodic detection is real-time.
If access terminal moves closer to wireless device when Distance Shortened (both), wireless device
Monitoring process detects that the signal intensity of this access terminal is increasingly stronger, i.e. the value of signal intensity is increasing,
When this signal intensity is more than the first predetermined threshold value, then monitoring process can notify that wireless device will access eventually
The frequency range of end is switched to the first working frequency range by the second working frequency range.
Such as, if this access terminal moves closer to wireless router, when the reality that some moment detects
Time signal intensity more than-40dBm, then access terminal can be automatically switched to by 2.4GHz frequency range
5GHz frequency range.
In actual applications, popularizing, as ipad, mobile phone, PC, game machine etc. set along with information technoloy equipment
Standby all uses under 2.4GHz frequency range, if multiple devices use 2.4GHz frequency range simultaneously, then can cause it
Crowded to capacity, handling capacity numerical value degradation.Further, microwave oven, bluetooth, wireless mouse etc. also use
2.4GHz frequency range, they can disturb wifi signal, make networking speed slow down, cause network congestion.Therefore,
The embodiment of the present invention, will when the signal intensity current access terminal being detected is more than the first predetermined threshold value
This access terminal automatically switches to 5GHz frequency range from by 2.4GHz frequency range, thus avoids other to use
The equipment interconnection of 2.4GHz frequency range enters terminal and interferes, and promotes the data transmission efficiency of access terminal, carries
Rise user to surf the Net experience.
It should be noted that in embodiments of the present invention, between the first predetermined threshold value and the second predetermined threshold value
For being spaced the threshold value of N number of numerical value, between the two at a distance of certain critical distance, such threshold value sets phase
For only set a predetermined threshold value benefit be, it is to avoid access terminal before and after threshold value marginal value frequently
Toggle frequency range (such as, when only setting a threshold value-50dBm, then the work of-51dBm and-49dBm
Differing as frequency range, once signal intensity is between both, then working frequency range needs to toggle to beat),
Improve equipment performance.Such as, the first predetermined threshold value is-40dBm, and the second predetermined threshold value is-50dBm, when
When access terminal is gradually distance from wireless device, value (such as-45dBm) between two thresholds is then operated in
5GHz frequency range, when access terminal moves closer to wireless device, value between two thresholds is (such as-45
DBm) then it is operated in 2.4GHz frequency range, gives two frequency range switching sufficiently bufferings, it is ensured that network stabilization
Property.
In embodiments of the present invention, when access terminal request accesses wireless device, if this access terminal is worked as
This access terminal more than the first predetermined threshold value, is then accessed to the first working frequency range by front signal intensity, anti-
Only this access terminal is interfered by other equipment being in the second working frequency range, improves user's networking speed.
Subsequently, continue the detection real-time signal intensity of access terminal, at this real-time signal intensity less than the
During two predetermined threshold value, then automatically access terminal is switched to the second working frequency range by the first working frequency range, after
Continue and again detect when real-time signal intensity is more than the first predetermined threshold value, automatically by access terminal by second
Working frequency range switches to the first working frequency range, by setting two different threshold values, based on access terminal
Signal intensity, is automatically performed the switching of access terminal different operating frequency range, it is not necessary to user's manual switching works
Frequency range, automaticity is high.
With reference to Fig. 3, it is shown that a kind of based on wireless device the frequency band switching method of the embodiment of the present invention is real
