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；

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 Adjacent frequency interference between working channel frequency range and the default communications band of the access points that will be connected to.

Further, the above-mentioned access points that working channel frequency range is not belonging to predeterminated frequency scope is defined as target visit Ask access point, it is also possible to specifically include:

Such as, mobile phone detects to meet has two to access access in the standby access points presetting low adjacent frequency disturbed condition The working channel frequency range of point is not belonging to predeterminated frequency scope, respectively first access points and second access points, and its work is believed Road frequency range is respectively 2431 2453MHz and 5151 5173MHz.Wherein, the signal of second access points is better than first access Access point, then second access points higher for signal preferentially can be defined as target access access point by mobile phone.

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 mobile phone obtain speed of preferably getting online without being tethered to a cable.

In step S205, mobile phone switches to this target access access point, and is defined as this target access access point working as Front access points.

Such as, after in step S204, target access access point determined by mobile phone, it is possible to control mobile phone and switch to this Target access access point, and this target access access point is defined as current accessed access point.

Due to relative to the access points that connected of mobile phone before switching, target access access point be being currently used Default communications band between frequency interval bigger, therefore by the wireless access points of mobile phone is switched to target access Access point can reduce the adjacent frequency between the currently used default communications band of mobile phone and the working channel frequency range of access points Interference.

In step S206, when determining that mobile phone does not uses default communications band to communicate, mobile phone searching can be accessed by Access points, and obtain the signal strength values of this accessible access points.

In step S207, mobile phone switches to the access points that this signal strength values is maximum.

Such as, step S206 and S207 can specifically include:

When determining that user carries out VoLTE call, i.e. mobile phone not in use by default 2380 not in use by mobile phone When 2400MHz frequency range is conversed, because now presetting the working channel of the access points that communications band is connected with mobile phone No longer there is adjacent frequency to disturb between frequency range, so the access points that mobile phone searching is accessible now can be triggered, and obtain these The signal strength values of accessible access points, the access points current connected including mobile phone and standby access points Signal strength values.Then, mobile phone is switched to the access points that this signal strength values is maximum.

The access points maximum by mobile phone switches to this signal strength values, can make mobile phone obtain higher wireless Networking speed.

It should be noted that in above-mentioned steps S203, mobile phone is by judging the working channel frequency of current accessed access point Section belongs to the predeterminated frequency scope corresponding with presetting communications band can be with to the working channel frequency range determining current accessed access point Preset communications band and produce adjacent frequency interference.And in the embodiment that other is possible, mobile phone can also come really otherwise The working channel frequency range of settled front access points can produce adjacent frequency interference with default communications band.Such as, can be by comparing The working channel of current accessed access point and the height of preset channel determine that the working channel frequency range of current accessed access point is No meeting and default communications band produce adjacent frequency interference, and this preset channel is corresponding with default communications band.It is understood that should The setting of preset channel is closely related with the performance of mobile phone, so the concrete setting value of this preset channel can be by manufacturer or user It is set according to handset capability or the use demand of self, is not specifically limited herein.

Such as, default communications band is 2380 2400MHz, preset channel is 2.4GHz frequency range No. 2 corresponding channels, Its working channel frequency range is 2406 2428MHz.After mobile phone gets the working channel of current accessed access point, it is judged that current Whether the working channel of access points is higher than preset channel.If judging, the working channel of current accessed access point is the most pre- If channel, then may determine that the working channel frequency range of current accessed access point can produce adjacent frequency interference with default communications band.Example As, the working channel frequency range of current accessed access point is 2401 2423MHz, and No. 1 channel of corresponding 2.4GHz frequency range, mobile phone is sentenced Breaking and this No. 1 channel less than preset channel (No. 2 channels), the most now mobile phone can determine that the work letter of current accessed access point Road frequency range can produce adjacent frequency interference with default communications band.If judging, the working channel of current accessed access point is higher than presetting letter Road, then may determine that the working channel frequency range of current accessed access point will not produce adjacent frequency interference with default communications band.

For another example, default communications band is 2496 2516MHz, preset channel is 2.4GHz frequency range No. 13 corresponding letters Road, its working channel frequency range is 2461 2483MHz.After mobile phone gets the working channel of current accessed access point, it is judged that Whether the working channel of current accessed access point is less than preset channel.If judging, the working channel of current accessed access point is the lowest In preset channel, then may determine that the working channel frequency range of current accessed access point can produce adjacent frequency with default communications band and do Disturb.If judging, the working channel of current accessed access point less than preset channel, then may determine that the work of current accessed access point Make channel bands and will not produce adjacent frequency interference with default communications band.Such as, the working channel frequency range of current accessed access point is 2456 2478MHz, No. 12 channels of corresponding 2.4GHz frequency range, mobile phone judges that these No. 12 channels are less than preset channel (No. 13 Channel), the most now mobile phone can determine that the working channel frequency range of current accessed access point will not produce with default communications band Adjacent frequency is disturbed.

Based on this, mobile phone, can be by working channel higher than (or being less than) preset channel when determining target access access point Standby access points be defined as target access access point.Such as, when default communications band is 2380 2400MHz frequency range, Working channel can be defined as target access access point higher than the standby access points of preset channel (No. 2 channels).And such as Really the working channel of the standby access points that mobile phone is accessible is below preset channel, then mobile phone can be by accessible standby The access points that in access points, working channel is the highest is defined as target access access point.Such as, mobile phone current accessed connects The working channel of access point is No. 1 channel, and the working channel of its accessible standby access points is below No. 2 letters preset Road, wherein comprises the standby access points that working channel is No. 2 channels, then this working channel can be 2 by mobile phone The standby access points of number channel is defined as target access access point.

If presetting communications band is 2496 2516MHz, then can be by working channel less than preset channel (No. 13 letters Road) standby access points be defined as target access access point.And if the work of the standby access points that mobile phone can be accessed by Be above preset channel as channel, then access minimum for working channel in accessible standby access points can be connect by mobile phone Access point is defined as target access access point.

For ease of the method preferably implementing the handover access access point that the embodiment of the present invention provides, the embodiment of the present invention is also The device of a kind of method based on above-mentioned handover access access point is provided.The wherein implication of noun and above-mentioned handover access access point Method in identical, implement the explanation that details is referred in embodiment of the method.

Refer to the structural representation of the device of the handover access access point that Fig. 3 a, Fig. 3 a provides for third embodiment of the invention Figure, this device may include that acquiring unit 301, detector unit 302, determines unit 303, and control unit 304.

Acquiring unit 301, for when determining that terminal is in default adjacent frequency disturbance state, obtains standby access and accesses Point, described standby access points is the accessible access points in addition to current accessed access point.

Such as, when terminal determines that it is in default adjacent frequency disturbance state, acquiring unit 301 the standby of terminal is obtained With access points, this standby access points is the accessible access points in addition to current accessed access point.

In a kind of possible embodiment, terminal can realize determining that terminal is in by performing following steps When presetting adjacent frequency disturbance state, obtain standby access points:

If based on described default communications band and the working channel frequency range of current accessed access point, determining that terminal is in pre- If adjacent frequency disturbance state, then obtain standby access points.

Further, if above-mentioned based on described default communications band with the working channel frequency range of current accessed access point, really Make terminal and be in default adjacent frequency disturbance state, then obtain standby access points, can specifically include:

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；

If judging, terminal is in default adjacent frequency disturbance state, then obtain standby access points.

Such as, terminal determine its be currently in use 2380 default 2400MHz frequency ranges carry out VoLTE call time, eventually End obtains the working channel frequency range of its current accessed access point connected.Such as, terminal gets current accessed access point Working channel frequency range is 2401 2423MHz.And the predeterminated frequency scope corresponding with default communications band that terminal is previously set It is 2400 2428MHz.It is understood that the predeterminated frequency scope being previously set is adjacent with default communications band, because of herein Signal frequency range in the range of predeterminated frequency can produce adjacent frequency interference with default communications band.

Then, whether the working channel frequency range of terminal detection current accessed access point belongs to preset communications band corresponding Predeterminated frequency scope.Such as, now terminal detects that working channel frequency range 2401 2423MHz of current accessed access point belongs to Predeterminated frequency scope 2400 2428MHz, then terminal may determine that and self is in default adjacent frequency disturbance state, i.e. terminal is connected Adjacent frequency interference is easily produced between working channel frequency range and the currently used default communications band of the current accessed access point connect. Coming from terminal judges is in after default adjacent frequency disturbance state, and the standby access that acquiring unit 301 obtains terminal accessible connects Access point.

If terminal detects that the working channel frequency range of current accessed access point is not belonging to preset communications band corresponding Predeterminated frequency scope, then show that the working channel frequency range of current accessed access point will not produce adjacent frequency with default communications band and do Disturbing, now terminal can be continuing with current accessed access point.

Detector unit 302, is used for detecting whether described standby access points meets default low adjacent frequency disturbed condition.

Such as, after acquiring unit 301 gets the standby access points that terminal is accessible, by detector unit 302 Detect whether this standby access points meets default low adjacent frequency disturbed condition.

In a kind of possible embodiment, this presets the work that low adjacent frequency disturbed condition can be standby access points Channel bands communicates frequently 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 section.Based on this, detector unit 302 can detect whether this standby access points meets as follows Default low adjacent frequency disturbed condition:

Determine the working channel frequency range of standby access points；

Such as, terminal gets 3 standby access points, and determines the work letter of the standby access points of these three Road frequency range is respectively 2406 2428MHz, 2431 2453MHz and 5151 5173MHz.It is then detected that unit 302 detects Whether the working channel frequency range of the standby access points of these three connects more than current accessed with the frequency interval of default communications band Working channel frequency range 2401 2423MHz of access point and the frequency interval of default communications band.Inspection by detector unit 302 Surveying, the working channel frequency range of the standby access points of above three and the frequency interval of default communications band are all higher than current accessed The working channel frequency range of access point and the frequency interval of default communications band.Therefore, the standby access points of these three is satisfied by Preset low adjacent frequency disturbed condition.

If detector unit 302 detects the working channel frequency range of the standby access points of terminal and default communications band The frequency interval of the frequency interval working channel frequency range no more than current accessed access point and default communications band, the most permissible Determine that these standby access points are all unsatisfactory for presetting low adjacent frequency disturbed condition, then terminal can be continuing with currently visiting Ask access point, or terminal can also temporarily disconnect and the connection of current accessed access point, to ensure that terminal is at default communication frequency Communication in section.

4th embodiment

In order to be more fully understood that the present invention, the present invention also provides for a kind of mobile terminal.

Refer to the structural representation of the mobile terminal that Fig. 4, Fig. 4 provide for the embodiment of the present invention.Concrete, mobile terminal 400 devices 410 including handover access access point, the device 410 of this handover access access point can be to appoint in above-described embodiment A kind of device of handover access access point.Concrete, the device 410 of this handover access access point can include acquiring unit 301, Detector unit 302, determine unit 303, control unit 304 and switch unit 305.Described acquiring unit 301, detector unit 302, determine that the function of unit 303, control unit 304 and switch unit 305 describes in detail, herein the most in the third embodiment Repeat no more.

In actual application scenarios, such as mobile terminal 400 uses certain higher frequency band in Band 40 frequency range to carry out VoLTE converses, and meanwhile, the wireless access points that mobile terminal 400 currently connects uses in 2.4GHz frequency range Relatively low frequency working channel, the most now easily produces adjacent frequency interference on mobile terminal 400.

In order to solve the problems referred to above, in a kind of possible embodiment, can determine that it is at mobile terminal 400 When using default communications band to communicate, mobile terminal 400 obtains the working channel of its current accessed access point connected Frequency range.Then, mobile terminal 400 is based on this default communications band and the working channel frequency range of current accessed access point, it is judged that move Whether dynamic terminal 400 is in default adjacent frequency disturbance state.

Such as, whether mobile terminal 400 belongs to logical with default by the working channel frequency range of detection current accessed access point The predeterminated frequency scope that letter frequency range is corresponding, judges self whether to be in default adjacent frequency disturbance state.If mobile terminal 400 detects The working channel frequency range going out current accessed access point is not belonging to the predeterminated frequency scope corresponding with presetting communications band, then judge Mobile terminal 400 is not at presetting adjacent frequency disturbance state, and now mobile terminal 400 can be continuing with current accessed access point. If mobile terminal 400 detects that the working channel frequency range of current accessed access point belongs to the default frequency corresponding with presetting communications band Rate scope, then judge that mobile terminal 400 is in default adjacent frequency disturbance state, and now the acquiring unit 301 of mobile terminal 400 can To obtain standby access points, this standby access points is the accessible access points in addition to current accessed access point.

After acquiring unit 301 gets standby access points, detector unit 302 detect this standby access and access Whether point meets is preset low adjacent frequency disturbed condition.Such as, this presets low adjacent frequency disturbed condition can be standby access points Frequency interval between working channel frequency range and default communications band is more than the working channel frequency range of current accessed access point with pre- If the frequency interval between communications band.

Based on this, mobile terminal 400 can first determine the work letter of the standby access points that acquiring unit 301 gets Road frequency range.Then detected between the working channel frequency range of standby access points and default communications band by detector unit 302 Frequency interval whether more than the frequency interval between working channel frequency range and the default communications band of current accessed access point.If Detect that the frequency interval between the working channel frequency range of standby access points and default communications band is not more than current accessed Frequency interval between working channel frequency range and the default communications band of access point, then detector unit 302 can determine that standby Access points is unsatisfactory for presetting low adjacent frequency disturbed condition.If detecting, the working channel frequency range of standby access points is with default Frequency interval between communications band is more than the frequency between working channel frequency range and the default communications band of current accessed access point Rate is spaced, then detector unit 302 can determine that standby access points meets and presets low adjacent frequency disturbed condition.

If the detector unit 302 of mobile terminal 400 detects not comprise in standby access points to meet presets low adjacent frequency The access points of disturbed condition, then mobile terminal 400 can be continuing with current accessed access point.If mobile terminal 400 Detector unit 302 detects to comprise in standby access points and meets the access points presetting low adjacent frequency disturbed condition, then move Dynamic terminal 400 can also detect to meet in the standby access points presetting low adjacent frequency disturbed condition whether comprise work further Channel bands is not belonging to the access points of predeterminated frequency scope.

If mobile terminal 400 detects to meet comprises work letter in the standby access points presetting low adjacent frequency disturbed condition Road frequency range is not belonging to the access points of predeterminated frequency scope, then mobile terminal 400 cell 303 really is by this working channel frequency Section is not belonging to the standby access points of predeterminated frequency scope and is defined as target access access point, and is controlled by control unit 304 Mobile terminal 400 switches to this target access access point.In a preferred embodiment, mobile terminal 400 order really Working channel frequency range preferentially can be not belonging to predeterminated frequency scope by unit 303 and the strongest standby access points of signal is defined as Target access access point.

If mobile terminal 400 detects to meet in the standby access points presetting low adjacent frequency disturbed condition does not comprise work Channel bands is not belonging to the access points of predeterminated frequency scope, i.e. meets the standby access access presetting low adjacent frequency disturbed condition The working channel frequency range of point belongs to predeterminated frequency scope, then mobile terminal 400 cell 303 really will meet default low adjacent frequency The standby access that in the standby access points of disturbed condition, working channel frequency range is maximum with the frequency interval of default communications band Access point is defined as target access access point, and is controlled mobile terminal 400 by control unit 304 and switch to this target access and access Point.

Switching to target access access point at mobile terminal 400, the switch unit 305 of mobile terminal 400 can also enter one Step ground is when determining that it communicates not in use by default communications band, and the accessible access of search mobile terminal 400 accesses Point, and obtain the signal strength values of these accessible access points, then by switch unit 305, mobile terminal 400 is cut Shift to the access points that this signal strength values is maximum.
