Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention
Embodiment be described in detail.It should be noted that in the absence of conflict, in the embodiment and embodiment in the application
Feature can mutual any combination.
Step shown in the flowchart of the accompanying drawings can be in a computer system such as a set of computer executable instructions
It executes.Also, although logical order is shown in flow charts, and it in some cases, can be to be different from herein suitable
Sequence executes shown or described step.
WiFi in the related technology disconnects strategy：During using WiFi network, according to AP whether also in WiFi
It is attached in the range of can scanning, if AP not in the range of WiFi can be scanned, i.e. the AP is arranged in WiFi
It has disappeared in table, at this moment selection disconnects AP；If AP enters in the range of WiFi can scan, i.e., the AP is appeared in again
In WiFi list, the AP at this moment can be actively connected.
Due to WiFi network quality be not only by end-probing to RSSI (Received Signal Strength
Indication, received signal strength indicator) value determines, other factors：The RSSI value of AP, the quality of channel itself and by
To interference also influence whether the quality of WiFi network.Specifically：If RSSI is low, rate is low or high (the packet loss of packet loss
Rate and rate can evaluate WiFi mass), but rate is low in turn or packet loss is high, and not necessarily RSSI is with regard to low,
In the case that RSSI is relatively high, it also will appear the situation that rate is low or packet loss is relatively high, it may be possible to due to interference, channel matter
Amount difference or directionality cause.Such as 1, WiFi is accessed in the more situation of people in public, not far from the feelings of AP
The RSSI that user receives under condition is relatively high, but the bandwidth that AP can give each user is limited, and results in WiFi network
It is second-rate；Such as 2, on the subway or motor-car of high-speed mobile, due to Doppler effect, terminal is caused not parse in time
The quality of the signal received out, WiFi network is also poor.
In order to solve the problems, such as that single RSSI because of data inaccuracy caused by interfering with doppler shift effect, utilizes terminal
With the correlativity of the RSSI value of access point, current network environment can be judged with assistant reinforcement, thus to provide corresponding plan
Slightly come determine disconnect or connect WiFi.
One embodiment of the invention provides a kind of WiFi connection control method, as shown in Figure 1, including：
Step 101, after terminal connection WiFi network, the rated signal intensity of the access point of the WiFi network, root are obtained
Signal strength section is determined according to the rated signal intensity；
Step 102, the actual signal intensity for obtaining the WiFi network of terminal measurement, when the actual signal intensity is located at
When except the signal strength section, the terminal disconnects the connection with described access point.
WiFi connection control method provided in this embodiment determines signal strength area according to the rated signal intensity of access point
Between, when the actual signal intensity that terminal detects is more than that the signal strength section just disconnects, compared to using in the related technology
Fixed individual signals intensity threshold, signal strength section is related with rated signal intensity in the application, can preferably embody net
Network quality.In addition, signal strength section is the section that the first signal strength and second signal intensity form.In the application, not only
The connection with access point is disconnected when actual signal intensity is outer on the left of signal strength section, when outer on the right side of signal strength section
Also the connection with access point is disconnected, compared in the related technology, is only broken when actual signal intensity is less than signal strength threshold
It opens, when there are multiple AP, the AP of terminal access is acted on by the amplification of other AP, and signal strength is very big at this time, but network matter
Bad, still maintenance WiFi connection in the related technology is measured, and uses this embodiment scheme, can be disconnected in time, to access
The better network of other performance.
In one embodiment, signal strength section is also possible to signal strength waving interval, and actual signal intensity is in signal
Refer to the difference of actual signal intensity and rated signal intensity except signal strength section except intensity interval.
Wherein, the signal strength can be RSSI.Wherein it is possible to obtain specified RSSI from Beacon frame.Furthermore it is possible to
Actual signal intensity is obtained from WiFi Service (service).
It is obtained by a large amount of data experiment and experience, the specified RSSI and terminal of the side AP (usually hot spot/router)
The RSSI of actual detection has certain linear relationship, which can be used as the index for determining WiFi network quality.It can
To obtain the nominal RSSI value (i.e. specified RSSI value, the hereinafter referred to as side AP RSSI value) of the side AP from Beacon frame, and it is corresponding
In terminal side, practical RSSI value (abbreviation terminal side RSSI value, similarly hereinafter) can be monitored by WiFi Service to reinforce sentencing
Disconnected current network environment.
Fig. 2 show the linear relationship between the side AP and the double RSSI in terminal side, if between the side AP and terminal side RSSI value
Linear relationship between two straight lines of y=ax+b (see Fig. 2 middle line 202) and y=cx+d (Fig. 2 middle line 201) (wherein x characterize
The RSSI value of the side AP, y characterize the RSSI value of terminal side), it was demonstrated that the consistency of current network is higher, the reception ability and AP of terminal
Emissivities it is consistent, terminal can exclude environmental disturbances and direction sexual factor；If linear relationship between this two line, is not said
The interference of bright surrounding wireless environment is bigger, and also the directionality between terminal and AP has relationship.And the side AP RSSI value is fixed, this
A linear relationship is from the environmental concerns for characterizing terminal and AP to a certain degree.In general, especially indoors in environment, a etc.
The space of disturbance fluctuation is just determined in the difference of c, b and d.Wherein, the slope, that is, a and c of two straight lines are empirical value, and b, d can
With measured in advance.For example, if the specified RSSI value of AP1 is x1, corresponding signal strength section is [y1, y2] to AP1,
The connection with AP1 is disconnected when beyond the section.To AP2, if the specified RSSI value of AP2 is x2, corresponding signal strength area
Between be [y3, y4], disconnected and the connection of AP2 when beyond the section.It can be seen that when specified RSSI difference, corresponding signal
Intensity interval is also different, so as to preferably reflect that real network quality carries out access control.It should be noted that Fig. 2 is only
Example, in other embodiments, the figure that the upper limit in its signal strength section different AP may also be constituted is not y=ax+b, and
It is a curve, the figure not instead of y=cx+d that the lower limit in its signal strength section different AP is constituted, a curve.To single AP,
Its signal strength section can be determined according to above-mentioned y=ax+b, y=cx+d, can also directly establish signal strength section and volume
Determine the mapping table of signal strength, table look-at obtains its signal strength section.Specifically, described obtain the rated signal
The corresponding signal strength section of intensity includes：
According to the first linear relationship curve (such as y=ax+b) of preset rated signal intensity and actual signal intensity,
The corresponding first actual signal intensity of the rated signal intensity of the access point of the WiFi network is determined, according to preset specified letter
Second linear relationship curve (for example, y=cx+d) of number intensity and actual signal intensity, determines the access point of the WiFi network
The corresponding second actual signal intensity of rated signal intensity, the first actual signal intensity and second actual signal are strong
The section that degree is constituted is the signal strength section；

The calculation and implementation strategy of double RSSI is as follows, this is sentenced for differential technique：When connecting for the first time, obtain AP and
The data of RSSI, for example the data of beacon broadcast of the side AP are -20dbm, and that terminal receives is -25dbm, then herein
Slope it is available be 1, then the sensor (motion sensor, gyro sensor) of terminal judges the movement of user at that time
State reacquires both lower value when motion state is opposing stationary, for example is respectively -20dbm, -45dbm, this fluctuation
Range can be taken as [- 5, -25], and corresponding signal strength section is [- 25, -45], i.e., subsequent fluctuation is just in this section
Often, not caused by this section can be judged as abnormal interference, when persistent anomaly interference is more than that this range just disconnects network company
It connects.
In the specific implementation, can be continued to obtain corresponding number with the mode of registration broadcast by taking android system as an example
According to, for example, using broadcast recipient persistently listen to WiFi Service obtain WiFi bottom state, and frame monitoring module,
The data broadcasting that packet loss monitoring module, signal strength monitoring module need is gone out.Alternatively, it is also possible to use monitoring kernel log
