Detailed description of the invention
Refer to graphic, the most identical element numbers represents identical assembly, and the principle of the present invention is to be implemented in one
Suitable computing environment illustrates.The following description is based on the illustrated specific embodiment of the invention, and it should be by
It is considered as limiting other specific embodiment that the present invention is the most detailed herein.
Will be detailed below.
First embodiment
A kind of method of handover access access point, including: when determining that terminal is in default adjacent frequency disturbance state, obtain
Standby access points, this standby access points is the accessible access points in addition to current accessed access point;Detection should
Whether standby access points meets is preset low adjacent frequency disturbed condition;If detecting that this standby access points meets to preset low neighbour
Frequently disturbed condition, then be defined as target access access point by this standby access points;Control terminal and switch to this target access
Access point.
Refer to the flow process signal that Fig. 1, Fig. 1 are the methods of the handover access access point that first embodiment of the invention provides
Figure, idiographic flow may include that
In step S101, when determining that terminal is in default adjacent frequency disturbance state, obtain standby access points, should
Standby access points is the accessible access points in addition to current accessed access point.
It is understood that the executive agent of the embodiment of the present invention can be the terminal unit such as mobile phone, panel computer.
Such as, the frequency range of the 2.4GHz frequency range that Wi-Fi uses is 2400 2483.5MHz, draws in this bandwidth
Divide and have 14 sub-channels.And the coverage of Band 40 frequency range is 2300 in the frequency range used by TDD-LTE communication technology
2400MHz, Band 41 the coverage of frequency range be 2496 2690MHz.Visible, that Wi-Fi uses 2.4GHz frequency range relatively low
Frequency part and higher-frequency part are close with the frequency of Band 40 and Band 41 frequency range of TDD-LTE respectively.Therefore, same when terminal
Time when using the 2.4GHz frequency range of Wi-Fi and Band 40 or Band 41 frequency range, it is easy to produce adjacent frequency interference.
It should be noted that adjacent frequency interference refers to interfering between the signal of adjacent or close channel.Owing to adjusting
Frequently signal contains infinite multiple side frequency component, when some of which side frequency component falls in the passband of neighboring trace receiver, and Jiu Huizao
Become adjacent frequency interference.During actual use, the signal of the adjacent frequency interference mainly side frequency of used signal frequency is done
Disturb, because receiving filter performance can not reach perfect condition, the signal of side frequency therefore can be caused to be leaked to transmission belt
Width is interior and causes interference.
In order to solve the problems referred to above, in step S101 of the embodiment of the present invention, can determine that it is in terminal pre-
If adjacent frequency disturbance state time, obtain terminal standby access points, this standby access points be except current accessed access
Accessible access points outside Dian.
Such as, in a kind of possible embodiment, in above-mentioned steps S101, when determining that terminal is in default adjacent frequency and does
When disturbing state, obtain standby access points, can specifically include:
When determining that terminal uses default communications band to communicate, obtain the working channel frequency of current accessed access point
Section;
If based on this default communications band and the working channel frequency range of current accessed access point, determining that terminal is in default
Adjacent frequency disturbance state, then obtain standby access points.
Such as, can terminal determine its be currently in use default communications band communicate time, obtain terminal connected
The working channel frequency range of current wireless access points (Access Point).Such as, pre-when determining that terminal is currently in use
If Band 40 frequency range when communicating, obtain the working channel frequency range of the current accessed access point of terminal.
Afterwards, terminal is based on above-mentioned default communications band and the working channel frequency range of current accessed access point, it is judged that terminal
Whether it is in default adjacent frequency disturbance state.
Such as, in a kind of possible embodiment, can judge whether terminal is in as follows default
Adjacent frequency disturbance state:
Whether the working channel frequency range of detection current accessed access point belongs to the predeterminated frequency corresponding with presetting communications band
Scope;
If detecting, the working channel frequency range of current accessed access point is not belonging to the default frequency corresponding with presetting communications band
Rate scope, then judge the adjacent frequency disturbance state that terminal is not at presetting;
If detecting, the working channel frequency range of current accessed access point belongs to the predeterminated frequency corresponding with presetting communications band
Scope, then judge that terminal is in default adjacent frequency disturbance state.
Such as, terminal, according to the performance of self, has preset the predeterminated frequency scope corresponding with default communications band,
This predeterminated frequency scope is adjacent with default communications band, is thus in the signal frequency range in the range of this predeterminated frequency and communicates with presetting
Adjacent frequency interference is there is between frequency range.
Therefore, in a kind of possible embodiment, when judging the adjacent frequency disturbance state that terminal is not at presetting, table
It is dry that the default communications band that bright terminal is being currently used and the working channel frequency range of wireless access points will not produce adjacent frequency
Disturb, then terminal can be continuing with the working channel frequency range of current default communications band and wireless access points.
When judging that terminal is in default adjacent frequency disturbance state, obtain terminal standby access points, laggard
Enter step S102.
It is understood that terminal can also determine whether to be in default adjacent frequency disturbance state otherwise.
Such as, by default monitoring application software, terminal can detect whether terminal is in default adjacent frequency disturbance state, etc..
In step s 102, detect whether this standby access points meets default low adjacent frequency disturbed condition.
Such as, after terminal gets standby access points, in step s 102, terminal detects this standby access access
Whether point meets the low adjacent frequency disturbed condition preset.
Such as, in a kind of possible embodiment, this presets low adjacent frequency disturbed condition can be standby access points
Working channel frequency range and default communications band frequency interval more than current accessed access point working channel frequency range with preset
The frequency interval of communications band.Based on this, can detect whether this standby access points meets default as follows
Low adjacent frequency disturbed condition:
Determine the working channel frequency range of standby access points;
Whether detect the working channel frequency range of this standby access points and the frequency interval of default communications band more than working as
The working channel frequency range of front access points and the frequency interval of default communications band;
If detecting, the working channel frequency range of this standby access points and the frequency interval of default communications band are more than working as
The working channel frequency range of front access points and the frequency interval of default communications band, it is determined that go out this standby access points full
Foot presets low adjacent frequency disturbed condition;
If detecting, the working channel frequency range of this standby access points is not more than with the frequency interval of default communications band
The working channel frequency range of current accessed access point and the frequency interval of default communications band, it is determined that go out this standby access points
It is unsatisfactory for presetting low adjacent frequency disturbed condition.
If it is understood that detecting the working channel frequency range of standby access points and the frequency of default communications band
Interval is not more than the working channel frequency range of current accessed access point and the frequency interval of default communications band, then show standby access
Adjacent frequency interference between working channel frequency range and the default communications band of access point is not less than the work letter of current accessed access point
Adjacent frequency interference between road frequency range and default communications band, now terminal can be continuing with the work letter of current accessed access point
Road frequency range.So, in the case of terminal detects the low adjacent frequency disturbed condition that its standby access points is unsatisfactory for presetting, eventually
End can be continuing with current accessed access point, i.e. enters step S105.
If detecting, the working channel frequency range of standby access points and the frequency interval of default communications band are more than current
The working channel frequency range of access points and the frequency interval of default communications band, then show the work letter of standby access points
Adjacent frequency interference between road frequency range with default communications band communicates with presetting less than the working channel frequency range of current accessed access point
Adjacent frequency interference between frequency range.Detect that standby access points meets the situation of default low adjacent frequency disturbed condition in terminal
Under, enter step S103.
In step s 103, if detecting that this standby access points meets to preset low adjacent frequency disturbed condition, then this is standby
It is defined as target access access point with access points.
Such as, terminal detects that the working channel frequency range of standby access points is big with the frequency interval of default communications band
Working channel frequency range and the frequency interval of default communications band in current accessed access point, then show relative to current accessed
Access point, the frequency interval between working channel frequency range and the default communications band of this standby access points is bigger, therefore phase
Compared with current accessed access point, the adjacent frequency interference between this standby access points and default communications band is less.In this feelings
Under condition, target access access point can be defined as by meeting the standby access points presetting low adjacent frequency disturbed condition.
Preferably, the above-mentioned standby access points by satisfied default low adjacent frequency disturbed condition is defined as target access access
Point, may include that
If detecting, comprising working channel frequency range in the standby access points meeting default low adjacent frequency disturbed condition does not belongs to
In the access points of predeterminated frequency scope, then the access points this working channel frequency range being not belonging to predeterminated frequency scope is true
It is set to target access access point;
If detecting, the working channel frequency range meeting the standby access points presetting low adjacent frequency disturbed condition belongs to pre-
If frequency range, then this is met working channel frequency range in the standby access points presetting low adjacent frequency disturbed condition and leads to presetting
The access points that the frequency interval of letter frequency range is maximum is defined as target access access point.
Such as, terminal searching is to having multiple standby access points meeting default low adjacent frequency disturbed condition, now terminal
Can be detected these meet in the standby access points presetting low adjacent frequency disturbed conditions and whether comprise working channel frequency range and do not belong to
Access points in predeterminated frequency scope.
If be detected that these meet comprises working channel frequency in the standby access points presetting low adjacent frequency disturbed condition
Section is not belonging to the access points of predeterminated frequency scope, then the access that this working channel frequency range is not belonging to predeterminated frequency scope connect
Access point is defined as target access access point.This is because the working channel frequency range outside predeterminated frequency scope and default communications band
Between do not exist adjacent frequency interference, the access points that therefore working channel frequency range can preferentially be not belonging to predeterminated frequency scope is true
It is set to target access access point.
If be detected that these working channel frequency ranges meeting the standby access points presetting low adjacent frequency disturbed condition are equal
Belong to predeterminated frequency scope, then show now to meet the working channel frequency of the standby access points of default low adjacent frequency disturbed condition
Adjacent frequency interference is all there is, then these can be met and preset the standby of low adjacent frequency disturbed condition between section and default communications band
The access points that in access points, working channel frequency range is maximum with the frequency interval of default communications band is defined as target and visits
Ask access point, thus farthest reduce between the default communications band of terminal and the working channel frequency range of access points
Adjacent frequency is disturbed.
Further, above-mentioned the access points that this working channel frequency range is not belonging to predeterminated frequency scope is defined as target
Access points, may include that
Working channel frequency range is not belonging to predeterminated frequency scope and the strongest access points of signal is defined as target access
Access point.
Such as, in the access points meeting default low adjacent frequency disturbed condition being detected, comprise working channel frequency range not belong to
After the access points of predeterminated frequency scope, it is also possible to their signal intensity of detection further, and by signal in them
The access points that intensity is the strongest is defined as target access access point.
It is defined as target by working channel frequency range being not belonging to predeterminated frequency scope and the strongest access points of signal
Access points, can make terminal obtain, while avoiding adjacent frequency interference, speed of preferably getting online without being tethered to a cable.
In step S104, control terminal and switch to this target access access point.
Such as, after terminal determines target access access point, control terminal and switch to this target access access point.
Preferably, after control terminal switches to the step of this target access access point, it is also possible to comprise the steps:
When determining that terminal does not uses default communications band to communicate, the access points that search terminal is accessible,
And obtain the signal strength values of the accessible access points of this terminal;
Terminal is switched to the access points that this signal strength values is maximum.
Such as, when determining that terminal communicates not in use by default communications band, such as terminal is not in use by Band
When 40 frequency ranges communicate, show that the adjacent frequency between the default communications band of terminal and the working channel frequency range of access points is done
Disturbing and no longer exist, now terminal may search for the access points that can be accessed by, and obtains these accessible access points
Signal strength values, including current accessed access point and the signal strength values of standby access points.Then, terminal is switched to this
The access points that signal strength values is maximum.
By terminal switches to the access points that signal is the strongest, terminal can be made to obtain speed of preferably getting online without being tethered to a cable
Degree.
From the foregoing, the method for the handover access access point of the present embodiment offer, default when determining that terminal is in
During adjacent frequency disturbance state, the terminal searching standby access points in addition to current accessed access point.Then, to detect this standby for terminal
Whether access points meets the low adjacent frequency disturbed condition preset.Detect that this standby access points meets default in terminal
In the case of low adjacent frequency disturbed condition, terminal is defined as target by meeting the standby access points presetting low adjacent frequency disturbed condition
Access points.Finally control terminal and be connected to this target access access point.Therefore, the present invention can be in default in terminal
During adjacent frequency disturbance state, by terminal switches to meet the standby access points of default low adjacent frequency disturbed condition, thus drop
The adjacent frequency interference of low terminal inner.
Second embodiment
According to the method described by first embodiment, as a example by mobile phone, method to handover access access point is made into one below
Step describes in detail.
Refer to the flow process signal of the method for the handover access access point that Fig. 2, Fig. 2 provide for second embodiment of the invention
Figure, idiographic flow may include that
In step s 201, mobile phone obtains present communications frequency range.
In step S202, if determining that mobile phone uses default communications band to communicate, then based on present communications frequency range
Mobile phone obtains the working channel frequency range of current accessed access point.
Such as, step S201 and S202 can specifically include:
When user uses mobile phone to carry out VoLTE (Voice over LTE) call, mobile phone acquisition is being currently used
Communications band.Then, whether mobile phone detection present communications frequency range belongs to default communications band.If detecting, present communications frequency range belongs to
In default communications band, then trigger mobile phone and obtain the working channel frequency range of its current wireless access points connected.
Such as, it is 2380 2400MHz that mobile phone gets its present communications frequency range, and detects present communications frequency range
2380 2400MHz belong to a default communications band in default Band 40 frequency range.Then, mobile phone obtains current wireless
The working channel frequency range of access points, the working channel frequency range of the current wireless access points as got is 2401
2423MHz, the i.e. working channel of current wireless access points are No. 1 channel of 2.4GHz frequency range.
After mobile phone gets the working channel frequency range of current wireless access points, mobile phone may determine that current wireless is visited
Ask whether the working channel frequency range of access point belongs to the predeterminated frequency scope corresponding with presetting communications band, such as this predeterminated frequency
Scope is 2400 2428MHz.
If mobile phone judges that the working channel frequency range of current wireless access points is not belonging to preset communications band corresponding
Predeterminated frequency scope, then show that the working channel frequency range of current wireless access points is higher, it is not easy to currently used
Preset communications band and produce adjacent frequency interference, then mobile phone can be continuing with current wireless access points.Such as, in step
The working channel frequency range of the current wireless access points that in S202, mobile phone gets is 5GHz frequency range, then current wireless accesses and connects
Adjacent frequency interference will not be produced, in this situation between the working channel frequency range of access point and the currently used default communications band of mobile phone
Under, mobile phone can be continuing with the working channel frequency range of current wireless access points.
If mobile phone judges that the working channel frequency range of current wireless access points belongs to predeterminated frequency scope, then show to work as
The working channel frequency range of front wireless access points is close with default communications band, easily produces adjacent frequency with default communications band and does
Disturb, now enter step S203.
In step S203, if mobile phone judges that the working channel frequency range of current accessed access point belongs to and presets the frequency that communicates
The predeterminated frequency scope that section is corresponding, then mobile phone obtains the working channel frequency range of standby access points, this standby access points
For the accessible access points in addition to current accessed access point.
Such as, mobile phone judge working channel frequency range 2401 2423MHz of current wireless access points belong to
In the case of presetting predeterminated frequency scope 2400 2428MHz that communications band is corresponding, show that the current wireless that mobile phone uses is visited
Ask that the working channel frequency range of access point easily produces adjacent frequency interference with currently used default communications band 2380 2400MHz,
Now mobile phone can go to obtain the working channel frequency range of standby access points, and this standby access points is for connecing except current accessed
Accessible access points outside access point.
Such as, mobile phone gets the working channel frequency range of 3 standby access points, and respectively 2406 2428MHz are (i.e.
No. 2 channels of 2.4GHz frequency range), 2431 2453MHz (i.e. No. 7 channels of 2.4GHz frequency range) and 5151 5173MHz are (i.e.
5GHz frequency range).
It is understood that in alternatively possible embodiment, mobile phone can also obtain the visit that it is accessible in advance
The information such as the working channel frequency range asking access point.Such as, can be after entering certain region, mobile phone searches for what it can be accessed by automatically
Access points, and obtain the information such as these accessible working channel frequency range of access points, signal intensitys, and protected
Exist in certain file preset.So, when mobile phone needs to obtain these information, mobile phone just can be directly from default literary composition
These information transferred by part folder.
Then, mobile phone judges the frequency of the working channel frequency range of standby access points and the default communications band got
Whether interval is more than the working channel frequency range of current accessed access point and the frequency interval of default communications band.
If mobile phone judges that the working channel frequency range of standby access points is little with the frequency interval of default communications band
In the frequency interval of working channel frequency range and the default communications band of current accessed access point, then show standby access points with
The adjacent frequency interference preset between communications band is disturbed not less than the adjacent frequency between current accessed access point and default communications band, this
Shi Shouji can be continuing with current accessed access point.
If mobile phone judges that the working channel frequency range of standby access points is more than with the frequency interval of default communications band
The working channel frequency range of current accessed access point and the frequency interval of default communications band, then enter step S204.
In step S204, if judging the working channel frequency range of standby access points and the frequency of default communications band
Interval is more than the working channel frequency range of current accessed access point and the frequency interval of default communications band, then mobile phone is by standby access
Access point is defined as target access access point.
Such as, if mobile phone judges the working channel frequency range of standby access points and the frequency interval of default communications band
More than working channel frequency range and the frequency interval of default communications band of current accessed access point, then show standby access points
And the adjacent frequency interference between default communications band is less than the adjacent frequency interference between current accessed access point and default communications band.
Such as, the working channel frequency range of 3 standby access points that mobile phone gets, respectively 2406 2428MHz,
2431 2453MHz and 5151 5173MHz, they are the biggest with the frequency interval of default communications band 2380 2400MHz
Working channel frequency range 2401 2423MHz and the frequency interval of default communications band in current accessed access point.Therefore, mobile phone
Any one in these 3 standby access points can be defined as target access access point.
It should be noted that the working channel frequency range that can calculate each access points in the following way is led to presetting
Frequency interval between letter frequency range.For example, it is possible to calculate the mid frequency of each access points and the center of default communications band
Frequency interval between frequency determines the frequency interval between two frequency ranges.Working channel frequency range such as current accessed access point
The mid frequency of 2401 2423MHZ is 2412MHz, and the center of currently used default communications band 2380 2400MHz
Frequency is 2390MHz, then the working channel frequency range of current accessed access point and the frequency interval of default communications band are 22MHz.
And the mid frequency of the standby access points that working channel frequency range is 2406 2428MHz is 2417MHz, it is with currently used
Default communications band mid frequency 2390MHz between frequency interval be 27MHz.Therefore, the work of standby access points
Make channel bands to communicate with presetting more than the working channel frequency range of current accessed access point with the frequency interval of default communications band
The frequency interval of frequency range.
Preferably, if step S204 is judged the working channel frequency range of standby access points and default communications band
Frequency interval is more than the working channel frequency range of current accessed access point and the frequency interval of default communications band, then mobile phone is by standby
Access points is defined as target access access point, can specifically include:
If judging, the working channel frequency range of standby access points and the frequency interval of default communications band are more than current
The working channel frequency range of access points and the frequency interval of default communications band, it is determined that go out standby access points and meet pre-
If low adjacent frequency disturbed condition;
If detecting, comprising working channel frequency range in the standby access points meeting default low adjacent frequency disturbed condition does not belongs to
In the access points of predeterminated frequency scope, then the access points this working channel frequency range being not belonging to predeterminated frequency scope is true
It is set to target access access point;
If detecting, the working channel frequency range meeting the standby access points presetting low adjacent frequency disturbed condition belongs to pre-
If frequency range, then this is met working channel frequency range in the standby access points presetting low adjacent frequency disturbed condition and leads to presetting
The access points that the frequency interval of letter frequency range is maximum is defined as target access access point.
Such as, 3 working channels meeting the standby access points presetting low adjacent frequency disturbed condition that mobile phone gets
Frequency range is respectively 2406 2428MHz, 2431 2453MHz and 5151 5173MHz.Wherein 2431 2453MHz and
5151 5173MHz the two working channel frequency ranges are not belonging to predeterminated frequency scope, then the two can preferentially be worked by mobile phone
Any one in the access points that channel bands is corresponding is defined as target access access point.
It is defined as target access access point by working channel frequency range being not belonging to the access points of predeterminated frequency scope,
The adjacent frequency interference can being prevented effectively between the working channel frequency range of access points and default communications band.Such as, by work
Channel bands is that the access points of 5151 5173MHz is defined as target access access point, because it is operated in 5GHz frequency range, institute
So that adjacent frequency interference will not be produced with the default communications band being operated in 2.4GHz frequency range.
If the working channel frequency range meeting the standby access points presetting low adjacent frequency disturbed condition belongs to predeterminated frequency
Scope, only gets 1 and meets the standby access points presetting low adjacent frequency disturbed condition, its working channel frequency range such as mobile phone
2406 2428MHz belong to predeterminated frequency scope.Because the standby access points meeting default low adjacent frequency disturbed condition only has 1
Individual, therefore it is and meets working channel frequency range and the default frequency that communicates in the standby access points presetting low adjacent frequency disturbed condition
The access points that the frequency interval of section is maximum, now mobile phone is defined as target access access point.
If belonging to preset owing to meeting the working channel frequency range of the standby access points presetting low adjacent frequency disturbed condition
Frequency range, then all have in various degree between working channel frequency range and the default communications band of these standby access points
Adjacent frequency disturb, so by by meet preset low adjacent frequency disturbed condition standby access points in working channel frequency range with preset
The access points of the frequency interval maximum of communications band is defined as target access access point, can farthest reduce mobile phone
