detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

It can be understood that the terms "first", "second" and the like used in the present invention can be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first client could be termed a second client, and, similarly, a second client could be termed a first client, without departing from the scope of the present invention. Both the first client and the second client are clients, but they are not the same client.

Fig. 1 is a flowchart of a wireless network scanning method in an embodiment. As shown in Figure 1, the wireless network scanning method includes steps S102 to S104, wherein:

Step S102, acquiring a parameter interval value between frequency attribute parameters of the first wireless network and the second wireless network.

In the embodiments provided by the present invention, a wireless network refers to a communication network formed by using radio waves as a medium for information transmission. Wherein, the wireless network can be divided into a wireless wide area network and a wireless local area network according to the size of the coverage area. A wireless wide area network refers to a wireless network that enables mobile users to communicate in a wide range, usually covering a city or a country or even a continent. For example, a wireless wide area network can be LTE (Long Term Evolution, Long Term Evolution) , CDMA (Code Division Multiple Access, Code Division Multiple Access), GSM (Global System for Mobile Communication, Global System for Mobile Communications). A wireless local area network refers to a wireless network that enables mobile users to communicate within a small range, usually only covering a range of tens of meters to hundreds of meters. For example, a wireless local area network can be a Wi-Fi (Wireless Fidelity, wireless fidelity ).

The frequency attribute parameter refers to an attribute parameter that can be used to represent the working frequency of the wireless network. For example, the frequency attribute parameter can be one or a combination of channel number, working frequency, and working bandwidth of the wireless network. Wherein, the channel refers to a signal channel using a wireless signal as a transmission medium. Operating frequency refers to the frequency of radio waves used to transmit communication signals. Operating bandwidth refers to the frequency width of radio waves used to transmit communication signals.

Wherein, the working frequency of the wireless network is divided into an uplink frequency and a downlink frequency, the uplink frequency refers to the transmission frequency of the wireless communication signal, and the downlink frequency refers to the reception frequency of the wireless communication signal. The difference between the uplink frequency and the downlink frequency is the working bandwidth. Different wireless networks work at different frequencies. Fig. 2 is a diagram showing working frequencies of different wireless networks in an embodiment. As shown in FIG. 2 , the illustration includes wireless network 202 , wireless network 204 , wireless network 206 , and wireless network 208 . Wherein, the working frequency of the wireless network 204 is 2300-2400MHZ, and the working bandwidth is 100MHZ; the working frequency of the wireless network 204 is 2402-2483.5MHZ, and the working bandwidth is 81.5MHZ; 4MHZ; the working frequency of the wireless network 208 is 2500-2690MHZ, and the working bandwidth is 190MHZ.

Furthermore, the parameter interval value refers to the difference between the frequency attribute parameter of the first wireless network and the frequency attribute parameter of the second wireless network. For example, the parameter interval value may be the uplink frequency of the wireless network, if the uplink frequency of the first wireless network is 2500MHZ, and the uplink frequency of the second wireless network is 2483.5MHZ, then the parameter interval between the first wireless network and the second wireless network The value is 16.5MHZ.

Since wireless networks transmit communication information through radio waves, different wireless networks are distinguished by different frequency attribute parameters. When the difference between the frequency attribute parameters of two wireless networks is very small, the wireless communication transmitted by the two wireless networks Information will interfere with each other. The smaller the value of the parameter interval, the greater the interference between the two wireless networks.

Step S104, if the parameter interval value is within the preset first parameter range, switch the scanning mode of the second wireless network to a passive scanning mode.

In the embodiment provided by the present invention, the preset first parameter range refers to a preset range of parameter interval values for determining whether to switch the scanning mode. When the parameter interval value is within the preset first parameter range, it is considered that there will be interference between the first wireless network and the second wireless network; when the parameter interval value exceeds the preset first parameter range, it is considered that the first wireless network There will be no interference between the network and the second wireless network.

Furthermore, the scanning mode refers to a mode in which an electronic device scans a wireless network, and can be divided into an active scanning mode and a passive scanning mode. The active scanning method means that the electronic device sends a request to detect wireless network signals on each channel, and a wireless network workstation will respond after receiving the request. The passive scanning method means that the electronic device regularly listens to the data packets sent by the wireless network workstation, and uses the data packets to identify and connect to the wireless network.

For example, when the mobile terminal scans wireless networks in an active scanning manner, it will send a Probe Request frame on the channel of each wireless network. Wherein, the Probe Request frame is a data packet used by the mobile terminal to request to establish a connection with the AP. After receiving the Probe Request frame, the AP (Wireless Access Point, wireless access point) will respond to establish a connection with the mobile terminal. When the mobile terminal scans the wireless network in the active scanning mode, if it is not connected to the surrounding APs due to reasons such as lack of AP keys, it will actively scan the surrounding available APs at regular intervals and try to connect. When the mobile terminal scans the wireless network in passive scanning mode, it will listen to the Beacon frame periodically sent by the AP to discover the wireless network. Wherein, the Beacon frame refers to a data packet sent by the AP to request to establish a connection with the terminal. The Beacon frame can contain information such as BSSID (Basic Station System Identifier, basic station system code), SSID (Service SetIdentifier, service set identifier), AP authentication method, AP encryption algorithm, Beacons frame transmission interval time, and channel number.

In the above wireless network scanning method, the interference between wireless networks is judged by acquiring the frequency attribute parameters of the wireless networks, and when interference occurs between the wireless networks, the scanning mode of the wireless network is switched to a passive scanning mode. Since in the passive scanning mode, the signal received by the electronic device from the wireless network workstation tends to attenuate to a very weak level, the interference generated by the electronic device between the received wireless network signals will also be reduced.

Fig. 3 is a flowchart of a wireless network scanning method in another embodiment. As shown in Figure 3, the wireless network scanning method includes steps S302 to S306, wherein:

Step S302, if it is detected that the preset service is executed through the first wireless network, then acquire the parameter interval value between the frequency attribute parameters of the first wireless network and the second wireless network.

In the embodiment provided by the present invention, the first wireless network and the second wireless network respectively represent different wireless networks, and the frequency attribute parameters of the first wireless network and the second wireless network are different. The preset service refers to a service performed by a pre-designated electronic device. For example, preset services may refer to services such as voice call, video call, and character transmission of the mobile terminal.

Furthermore, detecting that the preset service is executed through the first wireless network refers to detecting that the electronic device executes the preset service, and transmitting data of the preset service through the first wireless network. For example, the first wireless network and the second wireless network refer to LTE and Wi-Fi respectively, and the frequency attribute parameter refers to a working frequency band. When it is detected that the mobile terminal performs the voice service through LTE, the working frequency bands of the first wireless network and the second wireless network are acquired.

In one embodiment, if the first wireless network is a preset wireless network, the step of obtaining a parameter interval value between the frequency attribute parameters of the first wireless network and the second wireless network is performed. Wherein, the preset wireless network may be a pre-designated wireless network, or a pre-designated wireless network in a certain working frequency band, or a pre-designated wireless network of a certain channel number. For example, the designated wireless networks may be wireless network 202 and wireless network 206 shown in FIG. 2 . When the first wireless network is the preset wireless network, it is considered that there may be mutual interference between the first wireless network and the second wireless network.

The parameter interval value refers to the difference between the frequency attribute parameter of the first wireless network and the frequency attribute parameter of the second wireless network. For example, the frequency attribute parameter may be the working frequency band of the wireless network, the working frequency band of the first wireless network is 2300-2400MHZ, and the working frequency band of the second wireless network is 2496-2500MHZ. The parameter interval value may be defined as the interval value of the uplink frequency/downlink frequency of the first wireless network and the second wireless network, that is, 96/100MHZ.

In other embodiments provided by the present invention, the frequency attribute parameters may also be channel number and working bandwidth, and the channel number corresponds to the center frequency of the wireless network, and then the working frequency band of the wireless network can be calculated according to the center frequency and working bandwidth. Wherein, the central frequency refers to an intermediate value between an uplink frequency and a downlink frequency of the wireless network. For example, if the center frequency is 1000HMZ and the working bandwidth is 50MHZ, then the calculated working frequency band is 950-1050HMZ.

Since wireless networks transmit communication information through radio waves, wireless networks are distinguished by different frequency attribute parameters. When the frequency attribute parameters of the two wireless networks differ very little, the wireless communication information transmitted by the two wireless networks will interfere with each other. The smaller the parameter interval value, the greater the interference between the two wireless networks; on the contrary, the smaller the interference between the two wireless networks.

Step S304, if the parameter interval value is within the preset first parameter range, switch the scanning mode of the second wireless network to a passive scanning mode.

In the embodiment provided by the present invention, the preset first parameter range refers to a preset range of parameter interval values for determining whether to switch the scanning mode. When the parameter interval value is within the preset first parameter range, it is considered that there will be interference between the first wireless network and the second wireless network; when the parameter interval value exceeds the preset first parameter range, it is considered that the first wireless network There will be no interference between the network and the second wireless network.

Furthermore, the scanning mode refers to a mode in which an electronic device scans a wireless network, and can be specifically divided into an active scanning mode and a passive scanning mode. The active scanning method means that the electronic device sends a request to detect wireless network signals on each channel, and a wireless network workstation will respond after receiving the request. The passive scanning method means that the electronic device regularly listens to the data packets sent by the wireless network workstation, and uses the data packets to identify and connect to the wireless network.

In other embodiments provided by the present invention, when it is detected that the parameter interval value is within the preset second parameter range, the second wireless network is turned off. Wherein, the preset second parameter range is within the preset first parameter range. When the parameter interval value is within the preset second parameter range, it is considered that the interference between the first wireless network and the second wireless network is very large, and the second wireless network is directly closed; when the parameter interval value exceeds the preset second parameter range, but within the preset first parameter range, it is considered that the interference between the first wireless network and the second wireless network is very small, and it is only necessary to switch the scanning mode of the second wireless network to a passive scanning mode.

In step S306, if the execution of the preset service is completed, the scanning mode of the second wireless network is switched to an active scanning mode.

In one embodiment, when it is detected that the execution of the preset service ends or the first wireless network is closed, the scanning mode of the second wireless network is switched to an active scanning mode, so as to ensure that the electronic device can obtain available wireless networks in time.

In the above wireless network scanning method, the interference between wireless networks is judged by acquiring the frequency attribute parameters of the wireless networks, and when it is judged that there will be interference between the wireless networks, the scanning mode of the wireless network is switched to a passive scanning mode. Since in the passive scanning mode, the signal received by the electronic device from the wireless network workstation tends to attenuate to a very weak level, the interference generated by the electronic device between the received wireless network signals will also be reduced. When it is judged that the interference generated between the wireless networks is very large, directly shut down one of the wireless networks to avoid interference.

Fig. 4 is a flowchart of a wireless network scanning method in another embodiment. As shown in Figure 4, the wireless network scanning method includes steps S402 to S414, wherein:

Step S402, judging whether to use the LTE voice service, if yes, execute step S404; if not, continue to execute step S402.

In the embodiments provided by the present invention, the LTE voice service refers to voice services performed by using the wireless network LTE, for example, services such as voice calls and video calls through the wireless network LTE. Regularly detect whether to use the LTE voice service, and when it is detected that the electronic device uses the LTE voice service, then execute step S404; if no LTE voice service is detected, then execute step S402 in a loop.

Step S404, judging whether the interval between the LTE frequency band and the WLAN frequency band is greater than a preset interval, if yes, execute step S406; if not, execute step S408.

Specifically, the LTE frequency band refers to a working frequency band of the wireless network LTE performing voice services, and the WLAN frequency band refers to a working frequency band of the wireless network WLAN. If the interval value between the LTE frequency band and the WLAN frequency band is greater than the preset interval value, it is considered that there is no interference between the wireless network LTE and the wireless network WLAN, and then step S406 is performed; if the interval value between the LTE frequency band and the WLAN frequency band is less than or equal to the preset interval value, it is considered that there is interference between the wireless network LTE and the wireless network WLAN, and step S408 is executed.

In step S406, the wireless network WLAN maintains an active scanning mode.

Wherein, the initial scanning mode of the wireless network WLAN is an active scanning mode, and according to step S404 it is determined that there is no interference between the wireless network LTE and the wireless network WLAN, and the active scanning mode of the wireless network WLAN is maintained.

Step S408, switching the scanning mode of the WLAN from an active scanning mode to a passive scanning mode.

In the embodiment provided by the present invention, according to step S406, it is determined that there is interference between the wireless network LTE and the wireless network WLAN, and then the scanning mode of the wireless network WLAN is switched from an active scanning mode to a passive scanning mode.

Step S410, determine whether the LTE voice service is over, if not, execute step S412; if yes, execute step S414.

In one embodiment, it is determined whether the LTE voice service is over. When the LTE voice service is over, the signal of the wireless network WLAN will interfere with the execution of the LTE voice service, and step S414 is performed; otherwise, the signal of the wireless network WLAN will no longer interfere. For the execution of the LTE voice service, step S412 is performed.

Step S412, maintaining the passive scanning mode of the wireless network WLAN.

If the LTE voice service has not ended and it is considered that the signal of the wireless network WLAN will interfere with the execution of the LTE voice service, the passive scanning mode of the wireless network WLAN will continue to be maintained.

Step S414, switching the scanning mode of the WLAN from the passive scanning mode to the active scanning mode.

That is to say, if the LTE voice service ends, the signal of the wireless network WLAN will no longer interfere with the execution of the LTE voice service, and the scanning mode of the WLAN is switched from a passive scanning mode to an active scanning mode.

The above wireless network scanning device judges the interference between wireless networks by acquiring the frequency attribute parameters of the wireless networks, and switches the scanning mode of the wireless network to a passive scanning mode when interference occurs between the wireless networks. Since in the passive scanning mode, the signal received by the electronic device from the wireless network workstation tends to attenuate to a very weak level, the interference generated by the electronic device between the received wireless network signals will also be reduced.
