In the present embodiment, terminal prestores the information for being corresponding with the Wi-Fi hotspot of applicable value of each application.Terminal exists
When getting Wi-Fi hotspot to be accessed, judge whether each Wi-Fi hotspot to be accessed is to prestore Wi-Fi hotspot, i.e. judgement obtains
Whether application value information that whether each to be accessed Wi-Fi hotspot have current application is preserved in gridding information.Each waiting
Enter Wi-Fi hotspot and be when prestoring Wi-Fi hotspot to obtain from the gridding information of acquisition current application the running environment it is each to
Access the applicable value under Wi-Fi hotspot.When each Wi-Fi hotspot to be accessed is not to prestore Wi-Fi hotspot, i.e., terminal does not prestore
When the information of the Wi-Fi hotspot to be accessed got, determine these Wi-Fi hotspots for the Wi-Fi hotspot under new wireless network environment.

It determines the maximum Wi-Fi hotspot access of applicable value, and is saved so as to subsequent use, while terminal is in the WiFi for accessing selection
After hot spot, operation according to user to the application obtains the applicable value applied under current Wi-Fi hotspot and and right
The applicable value obtained before is updated, can be according to the application of application so that user is when entering the wireless network environment next time
Value selects Wi-Fi hotspot to access, so that the selection of Wi-Fi hotspot is more accurate.
Specifically, the process that terminal obtains applicable value of the current application under current Wi-Fi hotspot can be with are as follows:
Step S205, when each Wi-Fi hotspot to be accessed is not to prestore Wi-Fi hotspot, according to the operation ring of current application
Border and Internet resources determine the factor and weight of current application；
Step S206 generates the applicable value of the current application according to the determining factor and weight and by the current application
Applicable value, running environment association save into corresponding gridding information.
In the present embodiment, terminal prestores the applicable value of each application under each Wi-Fi hotspot, and each application in advance
Value is made of a certain number of factors and weight.Terminal is determined according to the running environment and Internet resources of the current application and is applied
The factor and weight, and according to the determining factor and weight generate the applicable value of the application and by the application of the current application
Value, running environment association save.In other embodiments of the present invention, it is also possible to the equipment by creation Wi-Fi hotspot (for example, road
By device, terminal with WiFi module etc.) with terminal the factor and weight of application are determined jointly.Equally, it is also possible on road
The factor and weight that application is determined by device etc. generate the applicable value of the application according to the determining factor and weight and work as by described in
The applicable value of preceding application, running environment association save and are synchronized to other into corresponding gridding information, and by the applicable value of generation
Router and/or terminal, so that other routers and/or terminal save the applicable value of each application.The definition of applicable value is such as
Under: { AppID Factor (factor) 1；Factor1_weight (weight of the factor 1)；Factor2；Foctor2_weight；
FoctorN；FactorN_weight；Value_under_ssid1；value_under_ssid2}.Wherein, AppID: for marking
Show application (separating each application area), Factor: the factor can be divided into two classes from the influence angle to application:
1. the fluency of application operation
Including user to the fluency of UI (user interface) response speed operated and playback of media files, this respect
The factor include: a, be applied to outer net specify IP address speed (bps)；B, using the speed (bps) with Intranet designated equipment
C, using the connection delay and response time (ms) with Intranet designated equipment；D, whether terminal can find (bool 0/ by outer net
1)；E, combination one or more in speed (bps) of outer net connection terminal etc..
2. the clarity of media
Clarity when terminal plays media
1) it is applied to the IP address shake (s) of designated equipment, shake expression is peak value and average up and down in transmission process
The deviation of value, this can be measured, using that can measure this data between router, if an application is HIFI
Song is listened, very high to shake requirement, then this application can be very high by the setting of the weight of shake, two routers, R1 has can
Outer net spee can be accessed quickly, but shake very big, it is general that R2 is possible to access outer net spee, but shake very little, answers at this time
With that can select R2, because the speed of R2 has fully met application demand, but the shake of R1 is not able to satisfy it.
2) whether router (Wi-Fi hotspot) supports jumbo frame (bool 0/1) jumbo frame that the maximum frame length of Ethernet is expanded
9K has been opened up, pervious maximum frame length is almost extended 6 times.Increasing frame length is advantageous in that, reduces data packet in network
Number, alleviate the overhead in network device processing packet header, this is whether router is supported, support be exactly 1, do not support
It is exactly 0, it is very high to efficiency requirements if an application is video playing application in 4k local area network, therefore this application can be right
Router is screened first, supports the preferential of jumbo frame.
Each factor has respective weight Factor_weight, reflects using the desirability to these factors, right
Applicable value influences bigger, and the weight accounted for is bigger, influences smaller, and the weight accounted for is smaller.
The factor for influencing application can have multiple, and the factor is by application [the corresponding weight of i.e. all factors default in a program
Value is set in application, and initial weighted value can be by 0 as initial value, and the later period can carry out according to the default scene of application
Dynamic assignment], it is desirable that it can measure.Value of each factor in specifiable lattice is and applies net that is related, and being currently located itself
Lattice are related related to current terminal.The corresponding value of the factor measures acquisition by terminal and router jointly.
Even we are simultaneously, it was also found that same apply under different business scenarios (i.e. running environment), to the factor
Requirement be also different, so we can adaptive Dynamic gene weight.
The adaptive adjustment of weight illustrated below.For example, having a player in mobile phone application, it can both be played
The video file downloaded in some NAS of Intranet equipment, can also play the video file on internet, in NAS
Video file, it can even go outer net find subtitle be used cooperatively.For this application, it will be assumed that current application setting
Running environment there are three the factor: Factor1: access outer net video server speed；Factor2: access NAS speed；
Factor3: access outer net subtitle server speed.
We can establish several application scenarios [i.e. by the functional attributes of application record user's selection as played local view
Frequency file, subtitle file is also in local so that it is determined that application scenarios].
S1: user plays local video file, and subtitle file is also in local
S2: user plays local video file, without subtitle file
S3: user plays the video file in NAS, has had subtitle file in NAS
S4: user plays the video file in NAS, without subtitle file in NAS
S5: user plays the 4K video file in NAS；
S6, user play the picture file in NAS；
It is following regular using establishing:
1, NAS demand is accessed, the basic weight of Factor2 is 50%, 50% weight is then required if it is picture, if it is
General video invitation is 70% weight, and if it is 4K video, then weight is increased to 80%
2, outer net video is accessed, the basic weight of Factor1 is 80%
3, need to access subtitle server, the basic weight of Factor3 is 20%, if the summation of weighted value adjusted is not
Then each weight is normalized when being 1.Using the template (rule of correspondence) for the weight for establishing the factor, concrete application field
Scape is matched in a template, finds the weight of each factor.
When scene switches, using the template of the weight according to the factor, adjust automatically weight [has been preset
The corresponding weighted value of each scene, for example above inside the example of video playing, I has been preset inside application each
The weighted value of the corresponding fixation of application scenarios (if it is S1, then needs for the weight for accessing Intranet to be added to 100%, and network
Reduce to 0%)], applicable value is calculated, switching WiFi signal is determined a need for.Weighted value does normalized as needed.
Using the power for determining which factor of needs and each factor according to current scene (i.e. current operating environment) self
Weight, then calculates the applicable value under some ssid connection, computation rule is as follows:
Value_under_ssidN=Σ FactorM_under_ssidN*FactorM_weight.It is answered by first determination
The factor and weight generate the applicable value of the application according still further to the determining factor and weight, and according to the operation ring of application
Border is different and is updated to applicable value, and the running environment difference where application obtains corresponding applicable value, and then can be more
Add accurately selection Wi-Fi hotspot access.
In the present embodiment, when getting Wi-Fi hotspot to be accessed, first judge the Wi-Fi hotspot to be accessed whether be
Wi-Fi hotspot is prestored, when the Wi-Fi hotspot to be accessed is not to prestore Wi-Fi hotspot, is directly accessed the Wi-Fi hotspot, and obtain
To the applicable value applied under current Wi-Fi hotspot and preservation, and current application no longer is obtained from the gridding information of acquisition
Applicable value under each Wi-Fi hotspot to be accessed of the running environment, saves the expense of system, and then improves the property of system
Can, and obtain and apply applicable value and preservation in the case where accessing Wi-Fi hotspot, so that next time can select according to the applicable value of application
Wi-Fi hotspot access, so that the selection of Wi-Fi hotspot is more accurate.
It is the flow diagram of the selection method fourth embodiment of Wi-Fi hotspot of the present invention referring to Fig. 4, Fig. 4.Based on above-mentioned
First to 3rd embodiment, and after the step S30, the selection method of the Wi-Fi hotspot includes:
Step S40, judges whether current application is greater than under other Wi-Fi hotspots in the applicable value under current Wi-Fi hotspot
Applicable value；
Step S50 is less than the application under other Wi-Fi hotspots in the applicable value under current Wi-Fi hotspot in current application
When value, the maximum Wi-Fi hotspot of applicable value of a current application is obtained from other Wi-Fi hotspots, and switches to current application
The maximum Wi-Fi hotspot of applicable value.
In the present embodiment, terminal is after the determining Wi-Fi hotspot of access, with the letter of the mobile Wi-Fi hotspot of terminal
Number intensity and the applicable value of corresponding application can change.Terminal judges that applicable value of the current application under current Wi-Fi hotspot is
It is no to be greater than applicable value under other Wi-Fi hotspots, for example, judge current application under current Wi-Fi hotspot current application to finger
Determine outer net IP address speed whether be greater than current application under other Wi-Fi hotspots to specified outer net IP address speed.Current
It applies when the applicable value under current Wi-Fi hotspot is less than applicable value of the current application under other Wi-Fi hotspots, from other WiFi
The maximum Wi-Fi hotspot of applicable value of a current application is obtained in hot spot, and the applicable value for switching to current application is maximum
Wi-Fi hotspot.For example, it is 100bps that current application, which arrives the speed of specified outer net IP address, under current WiFi, other Wi-Fi hotspots with
For three, under other Wi-Fi hotspots the speed of current application to specified outer net IP address be respectively 150bps, 90bps,
180bps determines there is the Wi-Fi hotspot bigger than the applicable value of current Wi-Fi hotspot current application in other Wi-Fi hotspots, and from
In other Wi-Fi hotspots, select current application to the maximum Wi-Fi hotspot for 180bps of speed of specified outer net IP address.Eventually
End select to switch to current application to specify the speed of outer net IP address for the Wi-Fi hotspot of 180bps.Terminal exists in current application
When applicable value under current Wi-Fi hotspot is greater than or equal to the applicable value under other Wi-Fi hotspots, without cutting for Wi-Fi hotspot
Change operation.It is understood that in order to which frequently current application is obtained and is compared in the applicable value of each Wi-Fi hotspot
Process leads to the expense of reduction system and the performance of system, presets a time interval, at interval of prefixed time interval, judgement is worked as
It is preceding to apply whether the applicable value under current Wi-Fi hotspot is greater than the applicable value under other Wi-Fi hotspots.Between the preset time

The factor include: a, be applied to outer net specify IP address speed (bps)；B, using the speed (bps) with Intranet designated equipment
C, using the connection delay and response time (ms) with Intranet designated equipment；D, whether terminal can find (bool 0/ by outer net
1)；E, combination one or more in speed (bps) of outer net connection terminal etc..
2. the clarity of media
Clarity when terminal plays media
1) it is applied to the IP address shake (s) of designated equipment, shake expression is peak value and average up and down in transmission process
The deviation of value, this can be measured, using that can measure this data between router, if an application is HIFI
Song is listened, very high to shake requirement, then this application can be very high by the setting of the weight of shake, two routers, R1 has can
Outer net spee can be accessed quickly, but shake very big, it is general that R2 is possible to access outer net spee, but shake very little, answers at this time
With that can select R2, because the speed of R2 has fully met application demand, but the shake of R1 is not able to satisfy it.
2) whether router (Wi-Fi hotspot) supports jumbo frame (bool 0/1) jumbo frame that the maximum frame length of Ethernet is expanded
9K has been opened up, pervious maximum frame length is almost extended 6 times.Increasing frame length is advantageous in that, reduces data packet in network
Number, alleviate the overhead in network device processing packet header, this is whether router is supported, support be exactly 1, do not support
It is exactly 0, it is very high to efficiency requirements if an application is video playing application in 4k local area network, therefore this application can be right
Router is screened first, supports the preferential of jumbo frame.
Each factor has respective weight Factor_weight, reflects using the desirability to these factors, right
Applicable value influences bigger, and the weight accounted for is bigger, influences smaller, and the weight accounted for is smaller.
The factor for influencing application can have multiple, and the factor is by application [the corresponding weight of i.e. all factors default in a program
Value is set in application, and initial weighted value can be by 0 as initial value, and the later period can carry out according to the default scene of application
Dynamic assignment], it is desirable that it can measure.Value of each factor in specifiable lattice is and applies net that is related, and being currently located itself
Lattice are related related to current terminal.The corresponding value of the factor measures acquisition by terminal and router jointly.
Even we are simultaneously, it was also found that same apply under different business scenarios (i.e. running environment), to the factor
Requirement be also different, so we can adaptive Dynamic gene weight.
The adaptive adjustment of weight illustrated below.For example, having a player in mobile phone application, it can both be played
The video file downloaded in some NAS of Intranet equipment, can also play the video file on internet, in NAS
Video file, it can even go outer net find subtitle be used cooperatively.For this application, it will be assumed that current application setting
Running environment there are three the factor: Factor1: access outer net video server speed；Factor2: access NAS speed；
Factor3: access outer net subtitle server speed.
We can establish several application scenarios [i.e. by the functional attributes of application record user's selection as played local view
Frequency file, subtitle file is also in local so that it is determined that application scenarios].
S1: user plays local video file, and subtitle file is also in local
S2: user plays local video file, without subtitle file
S3: user plays the video file in NAS, has had subtitle file in NAS
S4: user plays the video file in NAS, without subtitle file in NAS
S5: user plays the 4K video file in NAS；
S6, user play the picture file in NAS；
It is following regular using establishing:
1, NAS demand is accessed, the basic weight of Factor2 is 50%, 50% weight is then required if it is picture, if it is
General video invitation is 70% weight, and if it is 4K video, then weight is increased to 80%
2, outer net video is accessed, the basic weight of Factor1 is 80%
3, need to access subtitle server, the basic weight of Factor3 is 20%, if the summation of weighted value adjusted is not
Then each weight is normalized when being 1.Using the template (rule of correspondence) for the weight for establishing the factor, concrete application field
Scape is matched in a template, finds the weight of each factor.
When scene switches, using the template of the weight according to the factor, adjust automatically weight [has been preset
The corresponding weighted value of each scene, for example above inside the example of video playing, I has been preset inside application each
The weighted value of the corresponding fixation of application scenarios (if it is S1, then needs for the weight for accessing Intranet to be added to 100%, and network
Reduce to 0%)], applicable value is calculated, switching WiFi signal is determined a need for.Weighted value does normalized as needed.
Using the power for determining which factor of needs and each factor according to current scene (i.e. current operating environment) self
Weight, then calculates the applicable value under some ssid connection, computation rule is as follows:
Value_under_ssidN=Σ FactorM_under_ssidN*FactorM_weight.It is answered by first determination
The factor and weight generate the applicable value of the application according still further to the determining factor and weight, and according to the operation ring of application
Border is different and is updated to applicable value, and the running environment difference where application obtains corresponding applicable value, and then can be more
