Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are for purposes of illustration and not limitation. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of a wireless network scanning method provided in an embodiment of the present application, which is applicable to a situation where a terminal device scans a connectable device when performing network connection, and the method may be executed by the terminal device provided in the embodiment of the present application, and a wireless network scanning apparatus of the terminal device may be implemented in a software and/or hardware manner, as shown in fig. 1, a specific scheme provided in this embodiment is as follows:
step S101, when detecting that a wireless network scanning event is triggered, determining a current interference scene of the terminal equipment.
A wireless network (wireless network) is a network implemented using wireless communication technology. The wireless network comprises a global voice and data network allowing the terminal equipment to establish long-distance wireless connection, and also comprises an infrared technology and a radio frequency technology which are optimized for short-distance wireless connection, the purpose of the wireless network is very similar to that of a wired network, the biggest difference lies in the difference of transmission media, the wireless technology is used for replacing a network cable, and the wireless network and the wired network can be mutually backed up.
The wireless network scanning event may be triggered manually by a user, for example, when it is monitored that the WLAN control is clicked, signal scanning of the accessible device is started, or when the terminal device monitors that the network state changes (for example, network connection is disconnected), the wireless network scanning event is triggered.
When the terminal device scans a wireless network, it sends a scanning signal on a supported channel, and waits for a response signal of a peripheral accessible device, and due to the existence of an interference scene, the signal receiving sensitivity on some channels is poor, so that the scanning result in these channels is poor, and finally the scanned accessible device is inaccurate.
In one embodiment, taking an Android operating system as an example, when it is detected that Wifi is started, a network card is automatically opened and a wpa _ supplicant is started, and in this step, when it is detected that Wifi is started or wpa _ supplicant is called, a current interference scene of the terminal device is determined. The interference scenario is a scenario in which interference is generated on a wireless network scanning result, and may be an interference scenario generated by an internal interference source of the terminal device or an interference scenario generated by an external interference source of the terminal device. For example, the interference scenario corresponding to the internal interference source may be data transmission interference of a 4G network, and the interference scenario corresponding to the external interference source may be interference corresponding to other wireless network devices such as a bluetooth device (e.g., a bluetooth headset). In an embodiment, the determining of the current interference scenario of the terminal device may be determining the current interference scenario of the terminal device in real time when it is detected that the wireless network scanning event is triggered, or acquiring the interference scenario recorded by the terminal device as the interference scenario of the current terminal device.
Step S102, determining scanning time adjustment values of different channels corresponding to the interference scene, and adjusting a scanning time strategy in the wireless network scanning event according to the scanning time adjustment values.
The channel (also called frequency band) is a data signal transmission channel using wireless signals as transmission media, for example, the commonly used ieee802.11b/g works in the frequency band of 2.4 to 2.4835GHz, and these frequency bands are divided into 11 or 13 channels. Where different interference scenarios have different degrees of impact on different channels, the specific degree of impact may be determined by testing, which may be, for example, taking LTE B40 interference scenario as an example, test its interference to different WiFi channels, wherein, LTE (Long Term Evolution) is The Long Term Evolution of UMTS (Universal Mobile Telecommunications System) technical standard organized by 3GPP (The 3rd Generation Partnership Project), B40, i.e. band 40, refers to The operating frequency band (2300 + 2400Mhz), currently, LTE can support 40 working bands from B1 to B40, and different working bands generate different interference situations for different WiFi channels, WiFi channels at 2.4GHz according to international standard are divided into 13 channels (spanning frequency 2412 to frequency 2472), the interference of the LTE B40 to the WiFi 1 channel is 4db as obtained through the test.
In one embodiment, wireless network data transmission of different channels is tested in advance under different interference scenarios, signal intensity interference of the different interference scenarios on the different channels is determined, and corresponding scanning time adjustment values are set and recorded, wherein the scanning time adjustment values serve as a basis for determining scanning duration of the different channels in a subsequent wireless network scanning process, the scanning time adjustment values of the different channels corresponding to the different interference scenarios can be recorded and stored in a terminal device in a table form, and when a wireless network scanning event is triggered to determine an interference scenario of a current terminal device, the scanning time adjustment values of the interference scenario on the different channels are determined according to the recorded table. For example, the specific test procedure may be: respectively testing the signal intensity of each channel under the interference and non-interference conditions to determine the influence of an interference scene on the signal intensity of different channels, and further setting corresponding scanning time adjustment values, wherein the scanning time adjustment value corresponding to the stronger interference is larger, the smaller the interference is, and the smaller the corresponding scanning time adjustment value is, for example, when the interference intensity is 4db, the corresponding scanning time adjustment value is 100ms, and when the interference intensity is 0.2db, the scanning time adjustment value is 10 ms.
In another embodiment, the scanning signal strengths of different channels are tested in different interference scenarios, an accessible device with fixed signal strength can be set in each channel, and the scanning signal strengths of different channels are tested in different interference scenarios to determine the interference degree of the interference scenarios on different channels.
The terminal device scans different Wifi channels in the wireless network scanning process to obtain the accessible device for connection, and does not consider the situation that the scanning result of the terminal device is affected in an interference scene, namely that the scanning time of each channel is fixed in the prior art. For example, under the non-interference condition, the terminal device scans a WiFi 1 channel for 200ms to obtain an accessible device a, scans a WiFi2 channel for 200ms to an accessible device B and an accessible device C, and if the terminal device is in an interference scene (e.g., LTE B40 scene) at this time, the interference to the WiFi2 channel is strong, and at this time, the terminal device may not discover the accessible device or an accessible device during WiFi2 channel scanning for 200ms, that is, a scanning result is biased, thereby affecting a final connection result. In this step, scanning time adjustment values of different channels corresponding to the interference scenario are determined, and the scanning time policy in the wireless network scanning event is adjusted according to the scanning time adjustment values, for example, the scanning time adjustment value of the WiFi 1 channel is 100ms, and the scanning time of the scanning time adjustment value (100ms) is increased on the basis of the set default scanning time, so as to improve the probability of scanning the accessible device in the interference scenario.
In one embodiment, the adjustment of the scanning time strategy may be a way of overriding the original default scanning time, or a way of jumping to a new set scanning time.
And step S103, scanning different channels according to the adjusted scanning time strategy.
In one embodiment, scanning different channels according to the adjusted scanning time strategy comprises: and scanning different channels in sequence according to the scanning time corresponding to the scanning time adjustment values of different channels, or adding the scanning time adjustment values on the basis of default scanning time. For example, the interference scenario determined in step S101 is an LTE B40 scenario, the scanning time adjustment values in the corresponding Wifi channels 1 to 13 are determined to be 100ms, 20ms, 50ms, 80ms, 70ms, 90ms, 30ms, 40ms, 50ms, and 80ms in sequence, and the adjustment policy modified in step S102 is assumed to be a form of adding the scanning time adjustment value to the default scanning time (e.g., 300ms), so that when channel scanning is performed in this step, the sequential scanning time of the channels 1 to 13 is: 400ms, 320ms, 350ms, 380ms, 370ms, 390ms, 330ms, 340ms, 350ms and 380 ms.
According to the above content, the interference parameters are introduced in the process of wireless network scanning by the terminal equipment, so that longer scanning time is set for the channel greatly affected by the interference, the influence on the wireless scanning result in the interference scene is reduced, and the scanning efficiency is improved.
Fig. 2 is a flowchart of another wireless network scanning method provided in the embodiment of the present application, where optionally, the determining a current interference scenario of a terminal device includes: determining a channel transmitting frequency band used by the terminal equipment; correspondingly, the determining the scan time adjustment value of the different channels corresponding to the interference scenario includes: and determining scanning time adjustment values of different channels corresponding to the channel transmitting frequency bands. As shown in fig. 2, the technical solution is as follows:
step S201, when detecting that a wireless network scanning event is triggered, determining a channel transmission frequency band used by the terminal device.
The channel transmitting frequency band is a data transmitting and receiving frequency band when the terminal device uses a mobile network (such as GSM, 3G and 4G), the terminal device can use the mobile network to transmit and receive partial data simultaneously in the wireless network data transmission process of the access router, channel scanning of the terminal device can generate channel interference, different channel transmitting frequency bands have different interference degrees on different channel scanning signals, and the interference can be determined through software testing, wherein the interference comprises adjacent channel interference, frequency multiplication interference and the like. In this step, the channel transmission frequency band used by the terminal device (for example, the LTE B40 frequency band in the 4G mobile network is used) is determined.
Step S202, determining scanning time adjustment values of different channels corresponding to the channel transmitting frequency bands, and adjusting scanning time strategies in the wireless network scanning events according to the scanning time adjustment values.
Because the transmitting frequencies used by different channel transmitting frequency bands are different, the interference degrees of scanning signals corresponding to different Wifi channels are different, and different scanning time adjusting values are further set. Optionally, the terminal device stores and records a list of scanning time adjustment values of different Wifi channels corresponding to different channel transmission frequency bands, and determines the scanning time adjustment values of the different Wifi channels corresponding to the list after determining the channel transmission frequency band used by the terminal device. The process of adjusting the scanning time policy in the wireless network scanning event according to the scanning time adjustment value may adopt the method in step S102, and details are not repeated here.
And step S203, scanning different channels according to the adjusted scanning time strategy.
Therefore, when the terminal equipment scans the wireless network to obtain the accessible equipment, the mobile communication interference of the equipment is avoided, so that the final scanning result is more accurate, and the scanning efficiency is improved.
Fig. 3 is a flowchart of another wireless network scanning method provided in this embodiment, and optionally before determining the adjustment value of the scanning time of different channels corresponding to the channel transmission frequency band, the method further includes: determining the data transmission quantity of the terminal equipment in the channel transmission frequency band within a preset time; correspondingly, the determining the scanning time adjustment values of the different channels corresponding to the channel transmission frequency bands includes: and determining corresponding scanning time adjustment values of different channels according to the channel transmitting frequency band and the data transmitting quantity. As shown in fig. 3, the technical solution is as follows:
step S301, when detecting that the wireless network scanning event is triggered, determining a channel transmitting frequency band used by the terminal equipment.
Step S302, determining the data transmission quantity of the terminal equipment in the channel transmission frequency band within a preset time.
In one embodiment, the amount of data transmitted by the terminal device using the mobile network channel frequency band within a preset time (e.g., 30 minutes, 60 minutes, or 120 minutes) is recorded.
Step S303, determining corresponding scanning time adjustment values of different channels according to the channel transmitting frequency band and the data transmitting amount.
When determining the scanning time adjustment values of different channels, in addition to considering the aforementioned channel frequency band, the data transmission amount of the terminal device in the frequency band is further combined, and illustratively, the larger the data transmission amount is, the larger the scanning time adjustment value is, the smaller the data transmission amount is, and the smaller the scanning time adjustment value is.
And step S304, scanning different channels according to the adjusted scanning time strategy.
Therefore, when the terminal device performs channel scanning to determine the accessible device, the interference frequency band of the interference source and the data transmission amount are comprehensively considered to determine the influence of the interference source on the network scanning result, and then the reasonable scanning time is used to obtain an accurate scanning result, thereby further improving the scanning efficiency.
Fig. 4 is a flowchart of another wireless network scanning method provided in the embodiment of the present application, where optionally, the determining a current interference scenario of a terminal device includes: determining a wireless interference source of the current environment of the terminal equipment; correspondingly, the determining the scan time adjustment value of the different channels corresponding to the interference scenario includes: and determining scanning time adjustment values of different channels corresponding to the wireless interference source, wherein the wireless interference source comprises at least one of a Bluetooth interference source, a ZigBee interference source, a WiMax interference source and a microwave interference source. As shown in fig. 4, the technical solution is as follows:
step S401, when detecting that the wireless network scanning event is triggered, determining a wireless interference source of the environment where the terminal device is currently located.
The wireless interference source comprises at least one of a Bluetooth interference source, a ZigBee interference source, a WiMax interference source and a microwave interference source. In one embodiment, when a wireless network scanning event is detected to be triggered, a Bluetooth device currently connected with the terminal device is determined, or a stored record table is inquired to determine whether other wireless network interference sources exist (such as ZigBee interference sources are recorded).
Step S402, determining scanning time adjustment values of different channels corresponding to the wireless interference source, and adjusting a scanning time strategy in the wireless network scanning event according to the scanning time adjustment values.
In one embodiment, after the interference source is determined, a preset scanning time adjustment value list of different channels corresponding to different interference sources is queried according to different interference source types, and a scanning time adjustment value of the current interference source in each channel is determined. The manner of adjusting the scanning time policy in the wireless network scanning event according to the scanning time adjustment value may refer to step S102, which is not described herein again.
And S403, scanning different channels according to the adjusted scanning time strategy.
Therefore, when the terminal device performs channel scanning to determine the accessible device, the external wireless interference source is considered comprehensively, and the influence of the external wireless interference source on the channel scanning is considered, so that the channel scanning efficiency is improved.
Fig. 5 is a flowchart of another wireless network scanning method provided in the embodiment of the present application, and optionally, after scanning different channels according to the adjusted scanning time policy, the method further includes: and if the change of the interference scene of the terminal equipment is detected, adjusting the scanning time strategy according to the changed interference scene. As shown in fig. 5, the technical solution is as follows:
step S501, when the wireless network scanning event is triggered, determining the current interference scene of the terminal equipment.
Step S502, determining the scanning time adjustment values of different channels corresponding to the interference scene.
Step S503, adjusting the scanning time strategy in the wireless network scanning event according to the scanning time adjustment value.
And step S504, scanning different channels according to the adjusted scanning time strategy.
And step S505, monitoring the interference source scanned by the terminal equipment channel.
Illustratively, the data transceiving state of each frequency band is monitored through a wireless transceiving device (module) integrated with the terminal device.
And step S506, judging whether the interference scene of the terminal equipment is changed, if so, executing step S507, otherwise, continuing to monitor.
Step S507, adjusting the scanning time policy according to the changed interference scenario, performing channel scanning again in the background, and if a new accessible device is scanned and the signal strength of the accessible device is due to an existing connected accessible device, switching to connect to the new accessible device when the wireless network connection is idle.
When the interference scene of the terminal equipment is monitored to be changed (an interference source is newly added or reduced), the scanning time strategy is adjusted according to the changed interference scene, correspondingly, channel scanning is carried out again in the background, and if new accessible equipment is scanned and the signal intensity of the accessible equipment is due to the existing connected accessible equipment, the wireless network connection is switched and connected to the new accessible equipment when the wireless network connection is idle.
Therefore, the interference scene of the terminal equipment is monitored in real time, and the scanning time strategy is changed, so that the scanning time can be flexibly changed along with the interference scene, and the scanning result is more accurate. Optionally, after the interference scene changes, the currently changed interference scene is determined and recorded, so that a corresponding scanning time adjustment value is directly determined according to the recorded interference scene after a next wireless network scanning event is triggered, or the adjusted scanning time strategy is recorded, so as to be directly used for wireless network scanning.
