It is usually required to support multiple wireless access technologies in one device at the same time, such as: Long Term Evolution (LTE, Long Term Evolution) network and Wireless Local Area Network (WLAN, Wireless Local Area Networks) and so on. Since these access technologies are in the same or similar frequency bands, for example, the LTE spectrum is very close to the WLAN2.4GHz spectrum part, especially B40, B41, B7, etc., B40 is located below the WLAN frequency band, and B41 and B7 are located above the WLAN frequency band , when LTE works in the above frequency bands, interference with WLAN is unavoidable.

Currently, mobile terminals scan wireless access points (APs, Wireless Access Points) in two ways: active scanning and passive scanning. Active scanning means that a mobile terminal (workstation STA) sends a detection request ( Probe Request) frame, requesting a specific wireless network to respond, so when scanning, the mobile terminal will transmit a request signal. When the mobile terminal fails to connect to the AP (for example, there is no AP key), the mobile terminal will actively scan the surrounding available APs every once in a while and try to connect. If the user is using B7, B40 or B41 to make an LTE voice call at this time, it will inevitably cause adjacent channel interference and affect the user's normal call, resulting in poor call effect and call quality.

However, the principles of the present invention are described in the above words, which are not meant to be a limitation. Those skilled in the art will understand that the various steps and operations described below can also be implemented in hardware.

The principles of the invention operate with numerous other general purpose or special purpose computing, communication environments or configurations. Examples of well-known computing systems, environments, and configurations suitable for use with the present invention may include, but are not limited to, handheld phones, personal computers, servers, multiprocessor systems, microcomputer-based systems, mainframe computers, and A distributed computing environment, including any of the above systems or devices.

The details will be described respectively below.

In this embodiment, description will be made from the perspective of a wireless local area network channel scanning device (referred to as a channel scanning device), and the wireless local area network channel scanning device may specifically be integrated in a mobile terminal such as a tablet computer or a mobile phone.

A wireless local area network channel scanning method, comprising: when detecting that a mobile terminal is currently performing a preset voice call service, acquiring first frequency band information, the first frequency band information being the frequency band information used by the preset voice call service ; Obtain second frequency band information and channel information corresponding to the second frequency band information, the second frequency band information is the working frequency band information of the wireless local area network; determine the distance between the first frequency band information and the second frequency band information Frequency band spacing; if the frequency band spacing is less than a preset threshold, determine a corresponding target channel in the channel information, and scan the target channel.

Please refer to FIG. 1 . FIG. 1 is a schematic flow chart of a method for scanning a wireless local area network channel provided by an embodiment of the present invention. The methods include:

In step S101, when it is detected that the mobile terminal is currently performing a preset voice call service, first frequency band information is obtained, and the first frequency band information is information about a frequency band used by the preset voice call service.

In the embodiment of the present invention, the preset voice call service may specifically be the Long Term Evolution LTE voice service, which mainly refers to the communication or communication service between artificial voice and users or between users.

For example, when it is detected that the mobile terminal is currently performing an LTE voice service, information about the LTE frequency band used for the call is obtained, wherein, in the communication field, the frequency band refers to the frequency range of electromagnetic waves, and the unit is Hz.

In step S102, second frequency band information and channel information corresponding to the second frequency band information are acquired, where the second frequency band information is working frequency band information of the wireless local area network.

It is understandable that, according to the current spectrum division and use, the LTE spectrum is very close to the WLAN 2.4GHz spectrum, so when LTE also works in the 2.4GHz spectrum, there is inevitably interference between the two.

Based on this, in the embodiment of the present invention, the working frequency band information (second frequency band information) of the wireless local area network may specifically be the spectrum part of 2.4GHz (ie, 2402MHz to 2483.5MHz), and the corresponding channel information (Channel) of the working frequency band information includes CH1, CH2, ... CH13 a total of 13 channels.

It is easy to imagine that the terms "first", "second" and the like in the present invention are used to distinguish different objects, rather than to describe a specific order, and the examples here do not constitute a limitation of the present invention.

In step S103, the frequency band spacing between the first frequency band information and the second frequency band information is determined.

For example, according to the first frequency band information acquired in step S101 and the second frequency band information acquired in step S102, the frequency band spacing between the two is calculated. For example, if the frequency band information of LTE is 2300MHz and the frequency band information of WLAN is 2402MHz, then their The frequency band spacing between them is 102MHz.

In some implementations, if the frequency band spacing is smaller than a preset threshold, step S104 is performed.

In some implementations, after the channel scanning device determines the frequency band spacing between the first frequency band information and the second frequency band information, it may further include:

If the frequency band spacing is greater than or equal to a preset threshold, all channels indicated in the channel information are scanned.

It can be understood that when the frequency band spacing is greater than or equal to the preset threshold, it can be considered that the first frequency band information is far from the second frequency band information, that is, there is little or no interference between the preset voice call service and the wireless local area network , therefore, all channels indicated by the channel information corresponding to the second frequency band information may be scanned.

In step S104, if the frequency band spacing is smaller than a preset threshold, determine a corresponding target channel in the channel information, and scan the target channel.

In the embodiment of the present invention, there are many ways to determine the corresponding target channel in the channel information. For example, the following steps may be specifically included:

(1) Determine a corresponding preset interference level according to the frequency band spacing.

(2) Based on the preset interference level, determine the number of interference channels and corresponding interference channels.

(3) Among the channels indicated by the channel information, the interference channel is excluded, and the target channel to be scanned is determined.

That is to say, the channel scanning device can store the interference level in advance, and determine the corresponding interference level according to the frequency band spacing. For example, the larger the frequency band spacing, the greater the interference, and the higher the corresponding interference level; further, each interference level The number of channels that may cause interference to the preset voice service and the specific interference channel are preset. Finally, among all the channels, the interference channels are excluded, and the remaining channels are determined as the target channels.

In some implementation manners, the determining the corresponding preset interference level according to the frequency band spacing may specifically include:

(11) Obtaining multiple preset sub-thresholds, where the preset sub-thresholds are smaller than the preset threshold.

(12) Comparing the frequency band spacing with the plurality of preset sub-thresholds to obtain a comparison result.

(13) Determine a corresponding preset interference level according to the comparison result.

For example, in this embodiment, after it is determined that the frequency band spacing is smaller than the preset threshold, several intervals are divided by multiple preset sub-thresholds, and the frequency band spacing is compared with multiple preset sub-thresholds, then it can be determined that Which section the frequency band spacing belongs to, so that the corresponding interference level of the section can be determined.

In some embodiments, when the channel scanning device detects that the mobile terminal is not currently performing a preset voice call service, it may specifically include:

(a) When it is detected that the mobile terminal is not currently performing a preset voice call service, acquiring channel information corresponding to the working frequency band information of the wireless local area network.

(b) Scanning all channels indicated in the channel information.

It can be understood that when the mobile terminal is not currently performing a preset voice call service, it can be considered that there is no interference between the preset voice call service and the wireless local area network, therefore, all channels indicated by the channel information of the wireless local area network can be to scan.

As can be seen from the above, the wireless local area network channel scanning method provided by this embodiment firstly obtains the frequency band information used by the mobile terminal when it is detected that the mobile terminal is performing a preset voice call service; and obtains the frequency band information of the wireless local area network and the corresponding channel information; then, calculate the frequency band spacing between the frequency band information of the voice call and the frequency band information of the wireless local area network; if the frequency band spacing is less than the preset threshold, then determine the corresponding target channel in the channel of the wireless local area network and carry out the target channel Scanning to connect to the wireless access point, that is, by analyzing the frequency band spacing between the frequency band information of the voice call and the frequency band information of the wireless local area network, to determine the degree of interference between the two, and then determine the scanning based on the analysis results The target channel solves the problem that the wireless local area network of the mobile terminal actively scans the wireless access point, which affects the user's call, and ensures the effect and quality of the user's call.

According to the methods described in the above embodiments, examples will be given below for further detailed description.

First of all, due to the division and use of the existing spectrum, the LTE spectrum is very close to the WLAN2.4GHz spectrum part, especially the frequency bands B40, B41, B7, etc., B40 is located below the WLAN frequency band, and B41 and B7 are located above the WLAN frequency band , so when LTE works in the above frequency bands, there will inevitably be interference with WLAN, and according to the current technology level, the coexistence filter cannot guarantee to eliminate the interference of adjacent frequency bands.

For example, when a mobile terminal scans a wireless access point AP in an active scanning manner, it will send a probe request frame on each channel to request a specific wireless network to respond, so the mobile terminal will transmit a request signal during scanning. When the mobile terminal fails to connect to the AP (for example, there is no AP key), the mobile terminal will actively scan the surrounding available APs every once in a while and try to connect. However, if the user is using B7, B40 or B41 to make an LTE voice call at this time, it will cause adjacent channel interference and affect the user's normal call.

Based on this, embodiments of the present invention provide a new scanning mechanism to scan wireless local area network channels to avoid interference between LTE and WLAN. Please refer to FIG. 2 . FIG. 2 is another schematic flowchart of a channel scanning method for a wireless local area network provided by an embodiment of the present invention. The methods include:

In step S201, it is detected whether the mobile terminal is currently performing an LTE voice service.

For example, it is possible to detect whether the mobile terminal is currently performing an LTE voice service every preset time interval (such as 30 seconds, 1 minute, etc.), and when it is detected that the mobile terminal is currently performing an LTE voice service, step S202 is directly performed; When the mobile terminal is not currently performing the LTE voice service, step S209 is directly executed.

In step S202, the LTE frequency band information used by the LTE voice service is determined.

In step S203, frequency band information and corresponding channel information of the WLAN are obtained.

It is understandable that, according to the current spectrum division and use, the LTE spectrum is very close to the WLAN 2.4GHz spectrum, so when LTE also works in the 2.4GHz spectrum, there is inevitably interference between the two.

Therefore, when it is detected that the mobile terminal is currently performing LTE voice services, the current LTE frequency band information and WLAN working frequency band information are respectively obtained, so as to avoid interference.

Please refer to FIG. 3 together. FIG. 3 is a schematic diagram of the frequency band division of the wireless access network provided by the embodiment of the present invention. to 2483.5MHz), the channel information (Channel) corresponding to the working frequency band information includes CH1, CH2, ... CH13, a total of 13 channels.

As shown in Figure 3, the frequency bands that are relatively similar to LTE are frequency bands B40, B41, B7, etc. B40 is located below the WLAN frequency band, and B41 and B7 are located above the WLAN frequency band. Among them, the information of the B40 frequency band mainly includes 2300-2400MHz, and the information of the B41 frequency band It mainly includes 2496-2690MHz, and the B7 frequency band information is 2600MHz.

In step S204, the frequency band spacing between the LET frequency band information and the WLAN frequency band information is determined.

For example, according to the LET frequency band information obtained in step S202 and the WLAN working frequency band information obtained in step S203, the frequency band spacing between the two is calculated. If the frequency band information of LTE is 2300MHz and the frequency band information of WLAN is 2402MHz, then the The frequency band spacing is 102MHz.

In step S205, it is judged whether the frequency band spacing is smaller than a preset threshold.

If the frequency band spacing is smaller than the preset threshold, step S206 is directly performed; if the frequency band spacing is greater than or equal to the preset threshold, step S209 is directly performed.

It can be understood that the preset threshold can be determined according to the specific scene, if the scene requires more precise, then the preset threshold can be set relatively small, if the scene requirements are not high, then the preset threshold can be set relatively is relatively large, and its specific value is not limited here.

In step S206, multiple preset sub-thresholds are obtained, and the frequency band spacing is compared with the multiple preset sub-thresholds to obtain a comparison result.

In step S207, a corresponding preset interference level is determined according to the comparison result.

In step S208, based on the preset interference level, the target channel to be scanned is determined and scanned.

In step S209, all channels indicated in the frequency band information of the WLAN are scanned.

Specifically, for example, when the LTE is in a voice call, the mobile terminal obtains information about the currently used LTE frequency band, and if the distance between the frequency band used by LTE and the 2.4GHz frequency range of the WLAN is greater than or equal to the preset threshold, the WLAN is in full channel (CH1, CH2, ... CH13) to scan.

For another example, if the distance between the frequency band information used by the LTE and the 2.4 GHz frequency band range of the WLAN is smaller than a preset threshold, the WLAN adopts a partial channel scanning manner. If LTE uses the low channel in B41, in order to avoid interference, you can set CH13, CH12, CH11, etc. of WLAN to exclude it, and determine it as an interference channel.

It should be noted that the number of specific interfering channels can be determined according to the degree of mutual interference. Therefore, when the distance is determined to be smaller than the preset threshold, multiple sub-thresholds need to be set to distinguish multiple levels, so as to distinguish the degree of interference . The preset threshold can be used as threshold 1 to define whether full channel scanning or partial channel scanning is required, and multiple sub-thresholds can be set as threshold 2, threshold 3..., wherein threshold 1>threshold 2>threshold 3....

That is to say, the WLAN interference channel is determined according to the mutual interference, and the interference channel is excluded, and other channels are scanned to solve the impact on the user call when the mobile terminal WLAN actively scans the surrounding available APs, avoid interference, and improve user experience.

In addition, when it is detected that the mobile terminal is not currently performing the LTE voice service, it can be considered that there is no interference between the preset voice call service and the wireless local area network, and therefore, all channels of the WLAN can be scanned.

As can be seen from the above, the wireless local area network channel scanning method provided by this embodiment firstly obtains the frequency band information used by the mobile terminal when it is detected that the mobile terminal is performing a preset voice call service; and obtains the frequency band information of the wireless local area network and the corresponding channel information; then, calculate the frequency band spacing between the frequency band information of the voice call and the frequency band information of the wireless local area network; if the frequency band spacing is less than the preset threshold, then determine the corresponding target channel in the channel of the wireless local area network and carry out the target channel Scanning to connect to the wireless access point, that is, by analyzing the frequency band spacing between the frequency band information of the voice call and the frequency band information of the wireless local area network, to determine the degree of interference between the two, and then determine the scanning based on the analysis results The target channel solves the problem that the wireless local area network of the mobile terminal actively scans the wireless access point, which affects the user's call, and ensures the effect and quality of the user's call. That is, determine the WLAN interference channel based on mutual interference, exclude the interference channel, and scan other channels to solve the impact on user calls when the mobile terminal WLAN actively scans the surrounding available APs, avoid interference, and improve user experience.
