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 connection method provided in an embodiment of the present application, which is applicable to control when performing network connection on a terminal device, where the method may be executed by the terminal device provided in the embodiment of the present application, and a wireless network connection 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 connection 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 connection event may be triggered manually by a user, for example, the wireless network connection event is activated when it is detected that the WLAN control is clicked and a control binding event is executed correspondingly, or the wireless network connection event is activated and triggered when the terminal device detects that a network state changes (for example, network connection is disconnected).
Exemplarily, taking an Android operating system as an example, when it is detected that a connect () method of WifiManager is called, a current interference scenario of the terminal device is determined. The interference scenario is a scenario that interference is generated to wireless network data transmission, 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 connection 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 signal intensity adjustment values of different channels corresponding to the interference scene, and adjusting the routing strategy in the wireless network connection event according to the signal intensity 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 the LTEB 40 interference scenario as an example, the interference to different WiFi channels is tested, 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 operating bands from B1 to B40, and different operating 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 LTE B40 on 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 strength interference of the different interference scenarios on the different channels is determined, corresponding signal strength adjustment values are set and recorded, wherein the signal strength adjustment values serve as a basis for selecting a router in a subsequent wireless network connection process, the signal strength 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 after a wireless network connection event is triggered to determine an interference scenario of a current terminal device, the signal strength 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 strength of each channel under the interference and non-interference conditions to determine the influence of an interference scene on the signal strength of different channels, and further setting corresponding signal strength adjustment values, wherein the stronger the interference, the larger the corresponding signal strength adjustment value, the smaller the interference, and the smaller the corresponding signal strength adjustment value, for example, when the interference strength is 4db, the corresponding signal strength adjustment value is 10db, and when the interference strength is 0.2db, the signal strength adjustment value is-5 db.
The terminal device scans different Wifi channels in the wireless network connection process to obtain routers for connection, selects the router with the strongest scanned signal strength for connection, or connects the stored optimal router, and does not consider the situation that the terminal device generates interference on wireless network data in an interference scene. For example, the terminal device scans a router a with a signal intensity of a on a WiFi 1 channel, scans a router B with a signal intensity of 0.9a on a WiFi 4 channel, and connects with the router a according to an inherent routing policy, but if the terminal device generates a large amount of interference on data transmission of the WiFi 1 channel in an interference scene (e.g., an LTE B40 scene), the data transmission efficiency of the terminal device is significantly reduced, and the interference of the scene on the WiFi 4 channel is small, so that in an actual use process, the data transmission efficiency of the terminal device connected with the router B is higher, and the stability is stronger. In this step, the signal strength adjustment values of different channels corresponding to the interference scenario are determined, and the routing policy in the wireless network connection event is adjusted according to the signal strength adjustment values, for example, if the adjustment value of the WiFi 1 channel is 10db, the routing policy is correspondingly adjusted such that the signal strength of the WiFi 1 channel is higher than the signal strength of other channels by 10db for connection, so as to ensure that even if the LTE B40 is in a channel transmission state, the data transmission efficiency and stability of the WiFi 1 channel are better than those of other channels, and if the signal strength of the WiFi 1 channel is not higher than the signal strength of other channels by more than 10db, the routing of other channels is selected for connection.
In one embodiment, the adjustment of the routing policy may be to override the original router selection mode or to jump to a new set router selection mode. Taking an Android operating system as an example, saving router parameter information (including signal strength of a fixed channel scanned to a router) transmitted by a connect () method into a wificfigstore object, updating Priority attributes of the wificfigstore and config through a wificfigstore:: selectNetwork () function, and updating into a wpa _ s configuration file, in this step, when updating the Priority attributes, iterating the determined signal strength values of different channels into a set method function, and adjusting an original routing strategy by introducing signal strength adjustment value parameters of the different channels, optionally, the strategy adjustment is as follows: when updating the optimal router, if the signal intensity of the router scanned by the current channel minus the signal intensity adjustment value is greater than the recorded signal intensity of the optimal router, setting the currently scanned router as the optimal router, and continuing to scan the next channel.
And S103, selecting a router for wireless network connection according to the adjusted routing strategy.
In one embodiment, selecting a router for wireless network connection according to the adjusted routing policy comprises: and selecting the connected router for network connection according to the signal intensity adjustment values of the different channels and the signal intensity value of the scanned router in the fixed channel. For example, the interference scenario determined in step S101 is an LTE B40 scenario, the signal strength adjustment values in corresponding Wifi channels 1 to 13 are 10db, 2db, -5db, -8db, 7db, -9db, 3db, 4db, -4db, 5db, and 8db in sequence, it is assumed that there are 3 routers that can be connected to the current terminal device, which are respectively a router a, a router B, and a router c, default channels set by the routers are 1, 4, and 11 in sequence, when the terminal device performs wireless network connection, the signal strength scanned to channel 1 is 32db, the signal strength scanned to channel 4 is 30db, the signal strength scanned to channel 11 is 12db, and a router B is selected according to the routing policy adjusted in step S102 to perform network connection.
In another embodiment, the channels used by the router may also be set according to the signal strength adjustment values of different channels and network connection may be performed. For example, the signal strength adjustment values of Wifi channels 1 to 13 corresponding to the interference scenario 1 are 10db, 2db, -5db, -8db, 7db, -9db, 3db, 4db, -4db, 5db, and 8db in sequence, where the default channel of the router that can be connected is channel 1, the channel with the smallest interference scenario influence (the signal strength adjustment value is the smallest) is determined according to the signal strength adjustment values of channels 1 to 13, the router signal is set to the channel (e.g., channel 8 in this example), and network connection is performed with the router whose channel is set.
According to the above, after the network connection event is triggered, the current interference scenario of the terminal device is determined, and the routing strategy is adjusted in a targeted manner to ensure that the data transmission of the router connected in the interference scenario is more efficient and stable.
Fig. 2 is a flowchart of another wireless network connection 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 signal strength adjustment values of the different channels corresponding to the interference scenario includes: and determining signal intensity 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 the wireless network connection event is triggered, determining a channel transmission frequency band used by the terminal equipment.
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 during the wireless network data transmission process of the access router, channel interference can be generated on a wireless network accessed by the terminal device, different channel transmitting frequency bands have different interference degrees on different channels, 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 signal intensity adjustment values of different channels corresponding to the channel transmitting frequency bands, and adjusting the routing strategy in the wireless network connection event according to the signal intensity adjustment values.
The transmitting frequencies used by different channel transmitting frequency bands are different, so that the interference degrees of the different Wifi channels corresponding to the different channel transmitting frequency bands are different, and different signal intensity adjusting values are further set. Optionally, the terminal device stores and records a list of signal intensity adjustment values of different Wifi channels corresponding to different channel transmission frequency bands, and determines the signal intensity 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 routing policy in the wireless network connection event according to the signal strength adjustment value may adopt the method in step S102, and details are not described here.

In one embodiment, the mobile data information transmission of the terminal device after accessing the wireless routing network is monitored and recorded, and the amount of data transmitted by the terminal device using the mobile network channel frequency band at a preset time (for example, 30 minutes, 60 minutes or 120 minutes) is recorded.
Step S303, determining signal intensity adjustment values of corresponding different channels according to the channel transmitting frequency band and the data transmitting quantity.
When determining the signal strength 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 signal strength adjustment value is, the smaller the data transmission amount is, and the smaller the signal strength adjustment value is.
And step S304, selecting a router for wireless network connection according to the adjusted routing strategy.
Therefore, when the terminal equipment selects the wireless routing network for connection, the interference frequency band of the interference source and the data transmission quantity are comprehensively considered to determine the influence of the interference source on the wireless routing network, and then the optimal route is selected for network connection, so that the data transmission efficiency and the transmission stability are improved.

As shown in fig. 4, the technical solution is as follows:
step S401, when detecting that the wireless network connection 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 connection event is detected to be triggered, the 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 signal intensity adjustment values of different channels corresponding to the wireless interference source, and adjusting the routing strategy in the wireless network connection event according to the signal intensity adjustment values.
In one embodiment, after the interference source is determined, a preset signal strength adjustment value list of different channels corresponding to different interference sources is queried according to different interference source types, and a signal strength adjustment value of the current interference source in each channel is determined. The manner of adjusting the routing policy in the wireless network connection event according to the signal strength adjustment value may refer to step S102, which is not described herein again.
And S403, selecting a router for wireless network connection according to the adjusted routing strategy.
Therefore, when the terminal equipment selects the wireless routing network for connection, the external wireless interference source is comprehensively considered, the influence of the external wireless interference source on wireless network transmission is considered, the optimal routing is further selected for network connection, and the data transmission efficiency and the transmission stability are improved.
Fig. 5 is a flowchart of another wireless network connection method provided in the embodiment of the present application, and optionally, after the selecting a router according to the adjusted routing policy to perform wireless network connection, the method further includes: and if the change of the interference scene of the terminal equipment is detected, adjusting the routing strategy according to the changed interference scene, and re-determining the connected router and performing network connection when the terminal equipment is in a network idle state. As shown in fig. 5, the technical solution is as follows:

And step S506, judging whether the interference scene of the terminal equipment is changed, if so, executing step S507, otherwise, continuing to monitor.
And step S507, adjusting the routing strategy according to the changed interference scene, and re-determining the connected router and performing network connection when the terminal equipment is in a network idle state.
When the interference scene of the terminal equipment is monitored to be changed (an interference source is newly added or reduced), the interference scene of the terminal equipment is redetermined to adjust the routing strategy, and in one embodiment, when the terminal equipment is in a network idle state, the router connected with the terminal equipment is redetermined according to the updated routing strategy and network connection is carried out.
Therefore, the route selection strategy is monitored and changed in real time on the interference scene of the terminal equipment, the scheme is further perfected, and the situation that the route selection strategy cannot be adaptively adjusted due to the change of an interference source so as to connect the router with lower data transmission rate is avoided.
