Embodiment
The embodiment of the present invention is described in further detail below by embodiment combination accompanying drawing.
Embodiment one
Cause network matter because of user or other factors to solve the current access point connected in the prior art
Quantitative change is poor, and terminal but can not switch to the more excellent access point of network quality by current access point automatically and carry out business transmission, so as to
The problem of reducing user experience, the embodiment of the present invention provide a kind of wireless access point switching method, refer to Fig. 1, Fig. 1 is
Wireless access point switching method flow chart provided in an embodiment of the present invention, it is comprised the following steps that：
S11, configure at least two network interface cards.
Specifically, at least two network interface cards of configuration can be wireless network card or be fictionalized by a wireless network card
At least two Microsoft Loopback Adapters；Established and communicated with access point by Microsoft Loopback Adapter, realize that business is transmitted.
S12, meet that the WAP of access conditions establishes communication link by least two network interface card and at least two
Connect.
Specifically, network interface card corresponds with WAP, wherein at least one Network card setup is work network interface card, and remaining is extremely
A few Network card setup is standby network interface card.Certainly, if user does not open automatic preferred network function, terminal will not pass through network interface card
Available wireless access point around detection in real time, also establish communicate with WAP accordingly, therefore, establish the premise of communication
It is that user opens automatic preferred network function, or, terminal automatically turns on the function.
Foregoing access conditions refers to that signal can cover terminal and the WAP that can normally connect, configuration it is each
Network interface card is established with one-to-one WAP and communicated to connect, and certainly, a WAP can also correspond to multiple network interface cards, respectively
Network interface card is communicated with same WAP.In addition, be work network interface card by least one Network card setup in the network interface card of configuration,
Remaining at least one Network card setup is standby network interface card, and work network interface card is used to carry out business transmission, and keeps communication connection；Standby net
Card is same to keep communication connection, but is not used in transmission services, and when the network interface card network quality that works is poor, work network interface card is switched to
Standby network interface card, original standby network interface card is switched into work network interface card, continue the transmission of business by the work network interface card, due to the work
Make network interface card (the standby network interface card before switching) and hold communication connection always, and simply switch over the state of network interface card (also i.e. by work
Standby network interface card is switched to as network interface card, standby network interface card switches to work network interface card) so that follow-up business directly passes through the work after switching
The corresponding WAP of network interface card is transmitted, so as to farthest ensure that terminal traffic will not cutting because of access point
Change and interrupt.
S13, the network quality of the corresponding WAP of each each Autonomous test of network interface card.
Specifically, the network interface card of configuration detects the network quality of corresponding WAP, according to the network of detection
Quality selects a WAP to switch over.Wherein, industry of the network quality between WAP and destination server
It is engaged in communication quality, namely the detection of each network interface card is service communication quality between WAP and destination server.Certainly,
It can be the service communication quality between WAP and network interface card；Pass through network delay, packet loss, theoretical bandwidth, actual band
The network quality Testing index such as width is weighed to network quality, to ensure that the WAP of selection is optimal as quality of connection
Access point, so as to farthest ensure that the network after switching is optimal network.
S14, using the network quality that each network interface card detects as one of factor is judged, the judgement of default switching condition is carried out, and
To be switched work network interface card and standby network interface card are determined, completes to switch according to judged result.
Specifically, network quality is by the network Testing index such as network delay, packet loss, theoretical bandwidth, actual bandwidth
Assessed, to judge that whether standby network interface card corresponds to the network quality of access point than the wireless access point network quality that currently connects
It is good, so as to provide more effective data for network switching.More specifically, network quality is preset as judge the factor a pair and cut
The condition of changing judged, namely according to network quality etc. judge the factor judge standby network interface card corresponding to WAP network matter
Whether amount is better than the network quality of WAP corresponding to work network interface card, certainly, not necessarily requires that standby network interface card corresponds to nothing
The network quality of line access point corresponds to the network quality of WAP better than work at present network interface card, as long as the standby network interface card is corresponding
The network quality of WAP integrally corresponds to the network quality of WAP than work at present network interface card.It is for example, current
The packet loss of WAP is relatively low corresponding to work network interface card, but network delay, actual bandwidth and theoretical bandwidth are poor, and standby
Network delay, the actual bandwidth of WAP are superior to the net of current wireless access point corresponding to a network interface card in network interface card
Network delay, actual bandwidth, but packet loss is higher than the packet loss of current wireless access point；To the less demanding situation of packet loss
Under, it is believed that the network quality of WAP will be due to the network quality of current wireless access point corresponding to the standby network interface card.
Therefore, can each WAP of comprehensive consideration the measurement index such as network quality, select most appropriate WAP to be cut
Change.Meanwhile when switching over, what is actually switched is network interface card, work network interface card that will be current switches to standby network interface card, will be to be cut
The standby network interface card changed switches to working net to stick into industry business transmission, farthest to ensure that the business of terminal will not be because of network interface card
Switch and interrupt.
In addition, before network interface card is switched, it is also contemplated that whether terminal is currently downloaded the Network of equicontinuity, if
Entering Line Continuity Network, may result in Network short interruption, completion is automatically continued after network connection and is downloaded.
Although this implementation provide wireless access point switching method can farthest ensure business will not because of network switching and in
It is disconnected, but minor impact can be still produced for continuity Network, therefore, it be not downloaded equicontinuity network industry
In the case of business, for application, network is being switched fast from the background, and the interim interruption of network is basic for user
It is invisible so that user has good usage experience.
Further, in S12 steps, work network interface card include it is at least one, business network interface card equally include it is at least one, when
When the network interface card that works includes at least two, there is the situation of network quality variation in subnetting card in the middle part of work network interface card, can be from standby net
The network interface card of quantity switches over corresponding to selection in card, only need to be by original working net to substitute original work network interface card transmission services
Card switches to standby network interface card, and the standby network interface card of business to be transmitted is switched into work network interface card.Need to understand, no matter standby network interface card, work
Make network interface card, establish communicate to connect with corresponding WAP all the time, in the armed state that can carry out business transmission at any time, one
When denier detects that network quality is better than the standby network interface card for the network quality that work at present network interface card corresponds to WAP, follow-up industry
Business is directly transmitted by the standby network interface card after switching, so as to farthest avoid because switching from current wireless access point
The situation of network interruption is caused to occur to next WAP.
In S13 steps, in addition to being detected to network quality, signal quality can also be detected, such as detected each wireless
The signal intensity of access point.The signal quality can be the service communication quality ginseng between WAP and destination server
Number, further confirms that the quality of connection of which WAP in each WAP is better than current by the signal quality
The WAP quality of connection of connection, so as to more accurately select an optimal WAP, be network switching for
More effective data.After each network interface card detects the signal quality of corresponding WAP, according to the letter of each network interface card detection
Number Quality estimation is better than the letter of at least one work network interface card detection with the presence or absence of the signal quality of at least one standby network interface card detection
Number quality, when the signal quality that at least one standby network interface card detection be present is better than the signal quality of at least one work network interface card detection
When, determine to be switched work network interface card and standby network interface card and complete to switch, namely determine to need the network interface card of carry out state switching, such as
Which work network interface card needs to switch to standby network interface card alternately, and which standby network interface card needs to switch to the progress of working net card subsequently
Business transmission.
The network quality that foregoing default switching condition includes at least one standby network interface card detection is better than at least one working net
Block the network quality of detection.It is better than the detection of at least one work network interface card when there is one in the network quality of standby network interface card detection
During network quality, using network interface card as to be switched standby network interface card, work network interface card is switched to replace work to be switched standby network interface card
Any one in network interface card, or be replaced according to priority；When standby network interface card detection network quality in exist at least two
It is individual due at least one work network interface card detection network quality when, using any one in the network quality as to be switched standby
Network interface card, the standby network interface card is switched into any one in work network interface card replacement work network interface card, or replaced according to priority
Change.
More specifically, for network quality and signal quality, according to the two connections of the dimension synthesis to WAP
Quality is assessed, and the good WAP of network quality is not that signal quality is good, similarly, the good WAP of signal quality
Not network quality is good, and the two is integrally preferably only the first choice of network switching, namely the network matter of to be switched WAP
Although amount and signal quality are not optimal in whole WAP, the two integrated connection quality is better than other nothings
Line access point, therefore, when carrying out network switching, comprehensive assessment goes out a suitable WAP and switched over.Similarly, it is right
Judge the factor in other, also can be as the criterion of WAP quality of connection.
Further, when foregoing WAP includes not connected WAP, according to set in advance enabled
Condition determines whether the WAP can be established with network interface card and communicated to connect.In the case where communication connection can be established, pass through
At least two network interface cards and the WAP that had been connected and meet that the WAP of the enabled condition is established and communicate.Tool
Body, it is contemplated that not connected WAP (including not connected opening WAP) may have potential safety hazard,
Therefore, a setting option can be increased in the terminal, whether set allows terminal to attempt the WAP that connection was not connected with,
It can then be established and communicated to connect by network interface card and the WAP in the case where function is enabled, so as in automatically switching network
In the case of the more excellent WAP of quality, it can also ensure user information safety.
Based on the switching method, terminal can switch to network quality from the access point of network quality difference automatically and preferably connect
Access point, meanwhile, it is capable to which ensuring the business of terminal to greatest extent will not interrupt because of network switching, greatly improve user's
Usage experience.
Embodiment two
The present embodiment is made further based on embodiment one by taking home scenarios as an example to wireless access point switching method
Explanation.In the scene, user's family has two wireless access point APs 1, and (Wireless Access Point, accessing wirelessly connect
Access point) and AP2, it is individually placed in parlor and study, and terminal had all connected, current AP1 correspondingly works network interface card, and AP2 is corresponding
Standby network interface card, work network interface card and standby network interface card are the Microsoft Loopback Adapters created by a wireless network card.Based on the Scene realization
The switching of WAP, Fig. 2 is referred to, Fig. 2 is that the WAP that the present embodiment provides switches schematic diagram, its specific switching
Process is as follows：
The U1 positions that terminal is currently in AP1 coverages are connected with AP1, and user is currently by terminal in parlor
APP (Application, application program) see TV.Now, terminal is connected to AP1 using work network interface card wlan1, and APP is corresponding
Surfed the Net also by AP1.In the case where user sets automatic preferred network to open, terminal detects the available wireless of surrounding in real time
Access point.The available wireless access point of surrounding is AP2, and the terminal in U1 positions is similarly in AP2 coverage, and terminal is led to
Cross wireless network card and create a standby network interface card wlan2, and connection AP2 is attempted using wlan2.But due to detecting AP2 letter
Number intensity is weaker than AP1, therefore, does not stick into industry business transmission using AP2 as working net, but connect as standby network interface card
AP2 and the network quality for detecting AP2.
User moves on to study reading from parlor now, such as black arrow in figure, the black arrow instruction user motion track,
User is moved to the U2 positions of AP2 coverages.With movement of the user to AP2 directions, AP1 signal intensity gradually weakens,
And AP2 signal intensity gradually strengthens, network interface card wlan1 and standby network interface card wlan2 is respectively to AP1 and AP2 network quality for work
Detected, such as detect the two network delay, packet loss, optimum wideband, actual bandwidth index, by These parameters, comment
The network quality for estimating to obtain AP2 is better than AP1 network quality, certainly, better than the movement of user, causes AP2 signal quality
Signal quality better than AP1.At the same time, whether detection present terminal internuncial Network such as is downloaded, and is not entering
In the case of Line Continuity Network, standby network interface card wlan2 corresponding to AP2 is switched into work network interface card wlan2, by AP1 pairs
The work network interface card wlan2 answered switches to standby network interface card wlan2, also switches over wlan1 and wlan2 working condition, by
Working, it is standby to switch to, and work is switched to by standby.For the application in terminal, network is just being carried out quickly from the background
Switching, in the case where carrying out the Network of noncontinuity, the interim interruption of network is not generally visible for user.
Need to understand, the work network interface card that the present embodiment is related to and standby network interface card in advance with corresponding wireless access point AP 1 and
AP2 establishes communication connection, in the case that then working net is stuck in carry out business transmission, though standby network interface card transmits without business,
But the maintenance state of communication is similarly in, business transmission can be carried out as needed at any time.Standby network interface card is corresponded in detection and wirelessly connect
While access point AP2 network quality, AP1 also carries out the detection of network quality during business is transmitted, and finally synthesis is commented
AP1 and AP2 network quality is estimated to judge whether to network switching so that user obtains more preferable network experience.
The present embodiment provide wireless access point switching method, by the network quality of each WAP of comprehensive assessment,
The indexs such as signal quality, the optimal WAP of a quality of connection is determined, and by the switching of network card status, quickly will
Network switches over, and the situation for avoiding re-establishing communication connection after switching occurs, so as to farthest ensure terminal traffic
It will not be interrupted because of network switching.
Embodiment three
The present embodiment is made further based on embodiment one by taking the scene of market as an example to wireless access point switching method
Explanation.In the scene, there are two wireless access point APs 1 and AP2, two access point terminals had all connected.Current AP1 is corresponding
Work network interface card, and AP2 corresponds to standby network interface card, and work network interface card and standby network interface card are the virtual nets created by a wireless network card
Card.Based on the switching of the Scene realization WAP, Fig. 3 is referred to, Fig. 3 is the WAP distribution that the present embodiment provides
Schematic diagram, specific handoff procedure are as follows：
Terminal is currently at the U1 positions in AP1 coverages, detects that the signal of other neighbouring wireless access point APs 2 is strong
Spend and be closer to AP1 signal intensity, terminal is connected to AP1 first by work network interface card wlan1.Set in user automatic preferred
In the case that network is opens, terminal detects the available wireless access point of surrounding in real time.The available wireless access point of surrounding is AP2,
It need to understand, the terminal in U1 positions is similarly in AP2 coverage.Terminal creates a standby network interface card by wireless network card
Wlan2, and attempt connection AP2 using wlan2.Because AP1 and AP2 signal intensity are similar, terminal will not be to work corresponding to AP1
The state for making network interface card wlan1 switches over, and the network interface card that will work switches to standby network interface card.
Because the number of users that AP1 WAPs are connected in market is more and more, although AP1 signal intensity and AP2
Signal intensity is closer to, but the network interface card wlan1 that works detects that the network quality values such as corresponding AP1 packet loss, network delay are bright
It is aobvious to rise, and standby network interface card wlan2 detects that the network quality values such as corresponding AP2 packet loss, network delay are still maintained at
Compare rational level, from many indexs such as signal intensity, network delay, packet loss, optimum wideband, actual bandwidth synthesis pair
AP1 and AP2 are assessed, and show that AP2 quality of connection is better than AP1 quality of connection.In Fig. 3, connect in AP1 current coverage ranges
4 terminals have been connect, have been A1, A2, A3, A4 respectively, wherein, the connection of U1 positions is A1；Only it is connected in AP2 current coverage ranges
1 terminal A5, because the terminal for connecting AP1 is significantly more than AP2, accordingly, AP1 packet loss, network delay after comprehensive assessment
Etc. index apparently higher than AP2 so that AP1 network quality is less than AP2 network quality.
Therefore, on the premise of ensuring that terminal is not downloaded equicontinuity Network, by working net corresponding to AP1
Card wlan1 switches to standby network interface card wlan1 so that follow-up network switching is prepared, and standby network interface card wlan2 is switched into work
Network interface card wlan2 continues follow-up business transmission.After network interface card switching, follow-up business directly by work network interface card wlan2 with it is wireless
Access point AP2 carries out business transmission, so as to avoid re-establishing the communication connection with wireless access point AP 2, causes network longer
The interruption of time.For the application in terminal, network is just carrying out quick switching from the background, is carrying out noncontinuity
In the case of Network, the interim interruption of network is not generally visible for user.
Example IV
A kind of WAP switching device is present embodiments provided, refers to Fig. 4, the device includes：
Network card configuration module 41, for configuring at least two network interface cards；
Communication module 42, for meeting that the WAP of access conditions is established by least two network interface cards and at least two

Network card setup is standby network interface card；
Network quality detection module 43, the network quality of the WAP corresponding for each Autonomous test of each network interface card,
Service communication quality of the network quality between WAP and destination server；
Access point handover module 44, for using the network quality that each network interface card detects as one of factor is judged, being preset
The judgement of switching condition, and to be switched work network interface card and standby network interface card during if desired for switching are determined, completed according to judged result
Switching.
Further, the foregoing judgement factor also includes signal quality, and the device also includes：
Signal quality detector module 45, for meeting access conditions by least two network interface card and at least two
WAP is established after communication connection, the signal quality of the corresponding WAP of each each Autonomous test of network interface card；
Signal quality judge module 46, the signal quality for being detected according to each network interface card judge whether at least one standby
The signal quality detected with network interface card is better than the signal quality that at least one work network interface card detects；
Access point handover module 47, for when the signal quality that at least one standby network interface card detection be present is better than at least one
During the signal quality of work network interface card detection, determine to be switched work network interface card and standby network interface card and complete to switch.
Wherein, when the network interface card that network card configuration module 41 configures is Microsoft Loopback Adapter, the function of the module can be by wireless network card
Realize, i.e., at least two Microsoft Loopback Adapters are created by wireless network card；Certainly, network card configuration module 41 can be also integrated in the terminal
Few two wireless network cards, network switching is carried out by least two wireless network cards.
The function of communication module can be realized that WIFI module includes hardware module and drives mould accordingly by WiFi module
Block, there is provided WiFi paths are communicated with access point.By WiFi module can virtual at least two Microsoft Loopback Adapters interface, wherein one
Individual interface is arranged to work network interface card and provides business transmission service for the application in terminal, and remaining network card interface is arranged to standby network interface card
For detecting the network quality and signal quality of other WAPs, and connection status is kept, but be not used in business transmission.
For network quality detection module 43, access point handover module 44, signal quality detector module 45 and access point
The function that handover module 46 is realized, can complete to operate by processor.
Further, in communication module 42, network interface card corresponds with WAP, wherein at least one Network card setup
For the network interface card that works, remaining at least one Network card setup is standby network interface card.Certainly, if user does not open automatic preferred network function,
Then terminal will not detect the available wireless access point of surrounding in real time by network interface card, also establish communicate with WAP accordingly,
Therefore, the premise for establishing communication is that user opens automatic preferred network function, or, terminal automatically turns on the function.
Foregoing access conditions refers to that signal can cover terminal and the WAP that can normally connect, configuration it is each
Network interface card is established with one-to-one WAP and communicated to connect, and certainly, a WAP can also correspond to multiple network interface cards, respectively
Network interface card is communicated with same WAP.In addition, be work network interface card by least one Network card setup in the network interface card of configuration,
Remaining at least one Network card setup is standby network interface card, and work network interface card is used to carry out business transmission, and keeps communication connection；Standby net
Card is same to keep communication connection, but is not used in transmission services, and when the network interface card network quality that works is poor, work network interface card is switched to
Standby network interface card, original standby network interface card is switched into work network interface card, continue the transmission of business by the work network interface card, due to the work
Make network interface card (the standby network interface card before switching) and hold communication connection always, and simply switch over the state of network interface card (also i.e. by work
Standby network interface card is switched to as network interface card, standby network interface card switches to work network interface card) so that follow-up business directly passes through the work after switching
The corresponding WAP of network interface card is transmitted, so as to farthest ensure that terminal traffic will not cutting because of access point
Change and interrupt.
In network quality detection module 43, the network interface card of configuration detects the network matter of corresponding WAP
Amount, a WAP is selected to switch over according to the network quality of detection.Wherein, network quality is WAP and mesh
The service communication quality between server is marked, namely the detection of each network interface card is business between WAP and destination server
Communication quality.It is of course also possible to it is the service communication quality between WAP and network interface card；By network delay, packet loss,
The network quality Testing index such as theoretical bandwidth, actual bandwidth is weighed to network quality, to ensure the WAP of selection
For the access point that quality of connection is optimal, so as to farthest ensure that the network after switching is optimal network.
The network quality being related in access point handover module 44 is by network delay, packet loss, theoretical bandwidth, actual band
The network Testing index such as width is assessed, to judge that whether standby network interface card corresponds to the network quality of access point than the nothing that currently connects
Line access point network quality is good, so as to provide more effective data for network switching.More specifically, using network quality as judgement
A pair of the factor default switching conditions are judged, namely according to network quality etc. judge the factor judge standby network interface card corresponding to nothing
Whether the network quality of line access point is better than the network quality of WAP corresponding to work network interface card, certainly, not necessarily
Ask for perfection and correspond to the network quality that the network quality of WAP correspond to better than work at present network interface card WAP with network interface card,
Will the standby network interface card correspond to the network matter of the overall WAP more corresponding than work at present network interface card of the network quality of WAP
Amount.For example, the packet loss of WAP is relatively low corresponding to work at present network interface card, but network delay, actual bandwidth and reason
It is poor by bandwidth, and network delay, the actual bandwidth of WAP are superior to corresponding to a network interface card in standby network interface card
Network delay, the actual bandwidth of current wireless access point, but packet loss is higher than the packet loss of current wireless access point；To losing
In the case that bag rate is less demanding, it is believed that the network quality of WAP corresponding to the standby network interface card will be due to current wireless
The network quality of access point.Therefore, can each WAP of comprehensive consideration the measurement index such as network quality, select most appropriate
WAP switches over.Meanwhile when switching over, what is actually switched is network interface card, work network interface card that will be current switches
For standby network interface card, working net is switched to stick into industry business transmission to be switched standby network interface card, farthest to ensure terminal
Business will not because network interface card switch and interrupt.
In addition, before network interface card is switched, it is also contemplated that whether terminal is currently downloaded the Network of equicontinuity, if
Entering Line Continuity Network, may result in Network short interruption, completion is automatically continued after network connection and is downloaded.
Although this implementation provide wireless access point switching method can farthest ensure business will not because of network switching and in
It is disconnected, but minor impact can be still produced for continuity Network, therefore, it be not downloaded equicontinuity network industry
