101, detection terminal connect whether succeed with AP；Step 103, if terminal and AP connection failure, newly-built being connect with AP for task；
Step 105, scan task operation has been detected whether, if so, terminating scan task；Step 107, times connecting with AP is executed
Business.Step 101-107 is described below.
Step 101, whether detection terminal is connect with AP succeeds.
In some embodiments, whether terminal 10 detects terminal 10 and connect with AP and succeed.The process packet that terminal is connect with AP
Include scanning, certification and association, wherein the purpose of scanning process is to scan available AP nearby, is connected for selection by the user
It connects.After user selects the AP to be connected, terminal sends ID authentication request, the authentication that AP sends terminal to the AP of selection
Request is verified, and if the verification passes, AP sends the response being verified to terminal.The ID authentication request of terminal is led to
After crossing, into association phase, terminal sends association request to AP, and AP returns to associated response to terminal, and so far, terminal is built with AP
Vertical connection, can mutually transfer data frame.Terminal 10 can also for example be led to by judging whether to receive the associated response of AP
Whether cross between judgement and AP can pass data frame mutually to detect whether and AP successful connection.
In some embodiments, before this step further include: receive the order connecting with AP.The scanning of terminal 10 can to nearby
After AP, AP is shown on the interface of terminal 10, user clicks selected AP, i.e., has issued connection selection to terminal 10
AP order, terminal 10 just starts the program connecting with AP.

Newly-built connecting with AP for task increases in the work queue 40 of wpa_supplicant there are two types of situation, a kind of situation are as follows:
As shown in Figure 2 a, there is no scan task before connecting task in work queue 40, then first carrying out connecting with AP for task, connect
Task not will receive the interference of scan task；Another situation are as follows: as shown in Figure 2 b, in work queue 40, connection task it
It is preceding to have had scan task, that is to say, that after terminal 10 creates connection task, when executing the connection task, to sweep
It retouches task just to perform, in response to this, the application subsequent step will do it processing.
Step 105, scan task operation has been detected whether, if so, terminating scan task.
In some embodiments, terminal has detected whether scan task operation, if so, terminating the scan task.Because
If there is scan task is run, connection task just needs to execute after the completion of scanning, due to needing one section of waiting time,
Cause connection task execution to be delayed, increase total time of connection task execution, the automatic connection speed of terminal is slower.
In some embodiments, whether this step further includes having scanning to appoint in the work queue for detect wpa_supplicant
Business is located at before connection task, if so, explanation has scan task to be carrying out at this time, then terminating the scan task, connects down
Connection task can be directly executed, needs not wait for and executes connection task after scan task is finished again.
In some embodiments, terminal finds network by listening to the beacon frame that AP is periodically sent, and terminal can also be according to
It is secondary to issue probe requests thereby (Probe Request) frame in multiple channels to find network.
Step 107, connecting with AP for task is executed.
In some embodiments, after terminating scan task, terminal 10 executes connecting with AP for task, including sends body to AP
The processes such as part certification request, association request.

Whether end has scan task running, if so, terminating the scan task, then there is no need to wait scan task to execute
Finish, and directly executes connecting with AP for task.By the scheme of the application, if terminal 10 and 20 First Contact Connections of access point lose
It loses, terminal 10 can create connecting with access point 20 for task, the task of the connection then be executed, at this moment if there is sweeping in terminal 10
It retouches task running, terminates the scan task, such connection task can be immediately performed, and not had to after the completion of scanning again
It executes, the time of a maximum scan period can be so saved, to improve what terminal 10 was connect automatically with access point 20
Speed.
Embodiment two
Fig. 4 is the flow diagram two of the present embodiment connection method, as shown in figure 4, the present embodiment connection method includes step
Rapid 201, detection terminal connect whether succeed with AP；Step 203, if terminal and AP connection failure, newly-built times being connect with AP
Business；Step 205, scan task operation has been detected whether, if so, obtaining scan task starts the time executed；Step 207,
Start the time that the time executed calculating scan task has executed according to scan task；Step 209, judge scan task
The time of execution accounts for the ratio of scan period, if ratio is more than or equal to preset threshold, step 211 is executed, if ratio is less than
Preset threshold executes step 213；Step 211, scan task is waited to be finished；Step 213, scan task is terminated；Step
215, execute connecting with AP for task.Step 201-215 is described below.
Step 201, whether detection terminal is connect with AP succeeds.
This step is essentially identical with step 101, please refers to the introduction of step 101.
Step 203, if terminal and AP connection failure, newly-built being connect with AP for task.
This step is essentially identical with step 103, please refers to the introduction of step 103.
Step 205, scan task operation has been detected whether, if so, obtaining scan task starts the time executed.
In some embodiments, terminal 10 has detected whether that scan task is being run, such as detection wpa_supplicant
Work queue in whether there is scan task to be located at before the connecting with AP of the task, also can detecte in the memory list of terminal 10
Whether there is or not scan tasks.If run without scan task, so that it may directly execution connection task；If there is scan task, obtain
Take scan task start execute time, that is, scan task since when execute.
Step 207, the time that the time executed calculating scan task has executed is started according to scan task.
In some embodiments, terminal 10 starts what the time executed calculating scan task had executed according to scan task
Time, that is to say, that terminal 10 with the now time subtract scan task start execute time can be obtained by scan task
The time executed.
Step 209, judge that time that scan task has executed accounts for the ratio of scan period, if ratio be more than or equal to it is pre-
If threshold value, step 211 is executed, if ratio is less than preset threshold, executes step 213.
In some embodiments, the scan period, which refers to, executes the time that single pass task needs, and terminal 10 is opened wirelessly
Function after, can at interval of the regular hour execute single pass task, periodically in target zone AP (such as Wifi heat
Point) it is scanned.In this step, terminal judges that the time that scan task has executed accounts for the ratio of scan period, that is, counts
It calculates the ratio that the time that scan task has executed accounts for the scan period and executes step if ratio is more than or equal to preset threshold
211, if ratio is less than preset threshold, execute step 213.Threshold value in this step can according to need specific setting, such as
80%, 90%, 95%, 99% etc..
In this step, judging that time that scan task has executed accounts for the ratio of scan period is to judge scan task
Have been carried out how many, if scan task has been carried out 95% or 99%, illustrates that scan task is carried out at once and finish
, step 211 is at this moment executed, waits scan task to be finished, because if at this moment terminating scan task, will cause terminal 10
The waste of system resource, scan task has been carried out most (such as 95% or 99%) after all.In such case
Under, wait scan task to be finished, that is, wait the very small part time (such as 5% or 1%) of scan period, with
It waits the most of the time (such as 80% of scan period) of scan period to compare, improves the speed that terminal is connect automatically with AP
Degree.
If the ratio that the time that scan task has executed accounts for the scan period is less than preset threshold, step 213 is executed, eventually
Only scan task.When ratio is less than preset threshold, illustrate that the task of scanning just performs sub-fraction, there are also most not to have
There is execution, at this moment if wait scan task to be finished executes the task of connection again, the time waited is with regard to some length, meeting
Cause connection speed slow, therefore, in the case, terminates scan task, need not thus scan task be waited to be finished, and
Step 215 is executed, that is, executes connecting with AP for task, to improve the speed that terminal 10 connects AP automatically.
Step 215, connecting with AP for task is executed.
This step is essentially identical with step 107, please refers to the introduction of step 107.
The present embodiment obtains scan task other than having the effect of embodiment one, and when there is scan task operation
Start the time executed, starts the time that the time executed calculating scan task has executed, judgement further according to the scan task
The time that scan task has executed accounts for the ratio of scan period, that is, judges scan task has been carried out how many, if
Ratio is more than or equal to preset threshold, illustrates that scan task is carried out at once and finishes, at this moment scan task is waited to be finished, because
If will cause the waste of 10 system resource of terminal at this moment to terminate scan task, it is big to have been carried out one for scan task after all
Part (such as 95% or 99%), has saved the system resource of terminal 10 in this way.And in the present embodiment, it waits to be scanned
Task execution finishes, that is, wait the scan period the very small part time (such as 5% or 1%), this with etc. it is to be scanned
The most of the time (such as 80% of scan period) in period is compared, and the speed that terminal is connect automatically with AP is improved.If swept
Retouch the time that task has executed account for the scan period ratio be less than preset threshold, illustrate scanning task just perform a small portion
Point, there are also most to be not carried out, and at this moment terminates scan task, it is not necessary to wait scan task to be finished, and directly execute
Being connect with AP for task, to improve the speed that terminal 10 connects AP automatically.
