Specific implementation mode
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is for explaining the present invention rather than limitation of the invention.It also should be noted that for the ease of retouching
It states, only the parts related to the present invention are shown in attached drawing rather than entire infrastructure.
Fig. 1 is a kind of flow chart of wireless network scanning method provided by the embodiments of the present application, is applicable to set in terminal
Standby the case where carrying out scanning connectable device when network connection, this method can by terminal device provided by the embodiments of the present application Lai
It executes, software can be used for the wireless network scan device of the terminal device and/or the mode of hardware is realized, as shown in Figure 1, this reality
The concrete scheme for applying example offer is as follows：
When step S101, detecting that wireless network scan event is triggered, the current interference scene of terminal device is determined.
Wireless network (wireless network) is the network realized using wireless communication technique.Wireless network both included
Allow terminal device to establish global voice and data network that remote-wireless connects, also includes being carried out near radio connection
The infrared technology and radio-frequency technique of optimization, very similar with the purposes of cable network, maximum difference is transmission medium
Difference replaces cable using radiotechnics, can backup each other with cable network.
Wherein, wireless network scan event access device (such as router, hot spot currently available for end of scan equipment
Equipment etc.), illustratively, which can manually be triggered by user, after such as monitoring that WLAN controls are clicked
The signal scanning for proceeding by accessible equipment can also be that terminal device monitors that network state changes (as disconnected net
Network connect) when activation trigger wireless network scan event.
Terminal device can send out scanning signal in the channel of support, wait for surrounding that can connect when carrying out wireless network scan
The response signal for entering equipment causes since the presence of interference scene makes the signal receiving sensitivity on some channels poor
Scanning result in these channels is poor, and it is inaccurate to eventually lead to the accessible equipment scanned.
In one embodiment, by taking Android operation system as an example, network interface card is automatically opened simultaneously after detecting that Wifi starts
Start wpa_supplicant, in this step after detecting that Wifi starts or wpa_supplicant is called, determines terminal
The current interference scene of equipment.Wherein, which is that the scene of interference is generated to wireless network scan result, can be eventually
The interference scene that end equipment internal interference source generates can also be the interference scene that terminal device external interference source generates.Citing
For, the corresponding interference scene in internal interference source can be the interference of 4G network data transmissions, and external interference source generates corresponding dry
It can be the corresponding interference of bluetooth equipment (such as bluetooth headset) other Wireless Communication Equipment to disturb scene.In one embodiment,
Determine that the current interference scene of terminal device can determine terminal in real time when detecting that wireless network scan event is triggered
The current interference scene of equipment can also be interference field of the interference scene for obtaining terminal device records as present terminal equipment
Scape.
Step S102, the sweep time adjusted value of determination and the corresponding different channels of the interference scene is swept according to described in
Time adjusted value is retouched to be adjusted the sweep time strategy in the wireless network scan event.
Wherein, channel (also known as frequency range) is the data-signal Transfer pipe using wireless signal as transmission media, such as common
IEEE802.11b/g be operated in 2.4~2.4835GHz frequency ranges, these frequency ranges are divided into 11 or 13 channels.It is wherein different
Interference scene is different to different channel effect degree, and specific influence degree can be determined by, illustratively, with LTE
For 40 interference scenes of B, its interference to different WiFi channels is tested, wherein and LTE (Long Term Evolution, for a long time
Evolution) it is by 3GPP (The 3rd Generation Partnership Project, third generation partner program) tissue
UMTS (Universal Mobile Telecommunications System, Universal Mobile Communication System) technical bid of formulation
Accurate long term evolution, B 40 are the frequency range (2300-2400Mhz) that band 40 refers to its work, and current LTE can support B 1 to B 40
Totally 40 working frequency range, the disturbed condition that different working frequency range generates different WiFi channels is different, according to international standard
The WiFi channels of 2.4GHz are divided into 13 channels (span is frequency 2412 to frequency 2472), such as obtain LTE B by test
The interference of 40 pairs of 1 channels of WiFi is 4db.
In one embodiment, the transmission of the wireless network data of different channels is surveyed under different interference scenes in advance
Examination determines that different interference scenes interfere the signal strength of different channels, is arranged and records corresponding sweep time adjusted value,
In, sweep time adjusted value as the foundation determined during follow-up wireless network scan to different channels duration scanning,
The sweep time adjusted value of the corresponding different channels of different interference scenes can in a tabular form record storage in terminal device, when
Wireless network scan event is triggered after the interference scene of determining present terminal equipment, and the table according to the record determines the interference
Sweep time adjusted value of the scene in different channels.Illustratively, specific test process can be：Respectively test have interference and
The signal strength of each channel under noiseless situation, to determine influence of the interference scene to different channels signal strength, Jin Ershe
Fixed corresponding sweep time adjusted value, wherein the more strong corresponding sweep time adjusted value of interference is bigger, and interference is smaller, corresponding
Sweep time adjusted value is smaller, and for example, when interference strength is 4db, corresponding sweep time adjusted value is 100ms, interference
When intensity is 0.2db, sweep time adjusted value is 10ms.
It in another embodiment, can to being tested the scanning signal intensity of different channels under different interference scenes
The accessible equipment of fixed signal intensity is set in each channel, test believes the scanning of different channels under different interference scenes

Terminal device can be scanned different Wifi channels during wireless network scan to obtain for connection
Accessible equipment, consider terminal device the case where scanning result can be affected under interference scene, i.e., existing skill
It is fixed when in art to the sweep time of each channel.For example, under noiseless situation, terminal device is in 1 channels of WiFi
Scanning scanning 200ms, obtains an accessible device A, is set with accessible in Wifi2 scan channels 200ms to accessible equipment B
Standby C, it is stronger to the interference of 2 channels of Wifi if terminal device is at this time under interference scene (such as 40 scenes of LTE B), this
When terminal device 2 scan channel 200ms of Wifi may can't had found to can access equipment or finding that one can access and set
Standby, i.e., there is deviation in scanning result, and then influences final connection result.Therefore in this step, determine and the interference scene pair
The sweep time adjusted value for the different channels answered, according to the sweep time adjusted value in the wireless network scan event
Sweep time strategy is adjusted, illustratively, the sweep time adjusted value 100ms of 1 channels of WiFi, then in the acquiescence of setting
Increase the sweep time of the sweep time adjusted value (100ms) on the basis of sweep time, is thus swept under interference scene with improving
Retouch the probability of accessible equipment.
