Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the technical problem of poor terminal internet access quality caused by a method of selecting a WiFi hotspot to access only according to the signal intensity of the WiFi hotspot in the conventional technology, in this embodiment, a method of connecting a WiFi hotspot is especially provided, the method can be implemented by relying on a computer program, the computer program can run on a computer system based on a von neumann system, and the computer system can be a computer device such as a smart phone, a notebook computer, a tablet computer, etc., which is provided with a wireless network card or a Wi-Fi chip. The computer program can be a Wi-Fi connection management program or a hotspot management program on an intelligent terminal such as a smart phone or a tablet computer.
Specifically, as shown in fig. 1, the method for connecting a WiFi hotspot includes the following steps S102 to S108:
step S102: and detecting a WiFi signal, and acquiring the hotspot identification of the detected WiFi hotspot, the hotspot signal strength and a target channel where the WiFi hotspot is located according to the WiFi signal.
In this embodiment, if the Wi-Fi connection on the smart terminal of the user is Set to the on state, the smart terminal is in the detection state for the Wi-Fi signal, and the Wi-Fi connection management program or the hot spot management program may obtain a hot spot Identifier, such as a Service Set Identifier (SSID) and a physical address (MAC), of the Wi-Fi signal detected by the Wi-Fi chip by calling a driver of the smart terminal. And combining the SSID and the MAC as hotspot identifiers, establishing an index according to the SSID, and then determining a specific Wi-Fi hotspot according to the MAC.
Since the same area may have wireless network coverage of multiple Wi-Fi hotspots, a Wi-Fi connection management program or a hotspot management program on the intelligent terminal may detect Wi-Fi signals of multiple channels, the Wi-Fi signal of each channel corresponds to one Wi-Fi hotspot, and an SSID broadcast in the Wi-Fi signal of each channel is the Wi-Fi hotspot corresponding to the Wi-Fi signal of the channel. In an area covered by a wireless network of a plurality of Wi-Fi hotspots, a Wi-Fi connection management program or a hotspot management program can obtain a list of hotspot identifications of the plurality of Wi-Fi hotspots by detecting Wi-Fi signals.
Correspondingly, the Wi-Fi connection management program or the hot spot management program on the intelligent terminal obtains the hot spot identification of the Wi-Fi signal detected by the Wi-Fi chip through the driving program of the intelligent terminal, and obtains the hot spot signal strength of the Wi-Fi signal detected by the Wi-Fi chip through the driving program of the intelligent terminal.
As shown in fig. 2, fig. 2 shows distribution diagrams of SSIDs 1,2, 3, and 4 on channels 1 and 6, and although the signal strength of SSID1 is optimal, there are two WiFi hotspots, SSID2 and SSID3, interfering on the same channel, whereas SSID4 is slightly weaker than SSID1, but only one WiFi hotspot, SSID4, is located on the 6 channel, and there is no signal interference on the same channel.
Therefore, in this embodiment, after acquiring the detected WiFi hotspot identification and the hotspot signal strength, a WiFi chip of the terminal needs to detect a channel where each detected WiFi hotspot is located.
Step S104: and acquiring the channel hot spot signal intensity of all channels adjacent to the target channel, and calculating a channel interference reference value corresponding to the target channel according to the channel hot spot signal intensity of all channels adjacent to the target channel.
After the channel where each detected WiFi hotspot is located is determined, the number of WiFi hotspots on each channel and the hotspot signal strength of each WiFi hotspot may be determined, and then the channel hotspot signal strength corresponding to each channel may be further obtained.
In this embodiment, whether a channel where a WiFi hotspot is located is interference to signals on other channels also affects the signal quality of the WiFi hotspot, because the signal quality of the WiFi hotspot with too much channel interference is not good.
Specifically, when calculating the channel interference corresponding to a certain channel, the channel interference reference value corresponding to the signal is calculated according to the channel signal strengths corresponding to all channels adjacent to the channel. For example, the channel interference reference value of the target channel may be calculated by calculating the sum of channel signal strengths corresponding to all channels adjacent to the signal. In specific implementation, a calculation formula of the channel interference reference value is preset, that is, a calculation formula for calculating the channel interference reference value corresponding to the signal according to the channel signal strengths corresponding to all channels adjacent to the target channel is determined.
Alternatively, in an embodiment, the channel interference reference value of the target channel may be a weighted sum of channel signal strengths of all adjacent channels.
Specifically, the step of calculating the channel interference reference value corresponding to the target channel according to the channel signal strengths of all channels adjacent to the target channel further includes: and acquiring a preset first weight coefficient, weighting the channel signal strengths of all the channels adjacent to the target channel according to the first weight coefficient, and generating a channel interference reference value corresponding to the target channel.
The weight coefficient of each adjacent channel is preset, and after all channels adjacent to the target channel and the corresponding channel signal strength are obtained, the channel signal strength of each adjacent channel can be weighted according to the weight coefficient, so that the channel interference reference value corresponding to the target channel is generated.
In particular toIf j is 1,2, …,8 adjacent channels exist in a certain channel, and the corresponding channel signal strength is ADJ _ RSSI1,ADJ_RSSI2,…,ADJ_RSSI8Then, the channel interference reference value result _ ADJ _ RSSI corresponding to the channel can be calculated by the following formula:
result_ADJ_RSSI＝ADJ_RSSI1+ADJ_RSSI2+…+ADJ_RSSI8。
because the interference effect of each channel on the target channel is different, the strength of the interference effect of each adjacent channel on the target channel needs to be considered. Specifically, each adjacent channel corresponds to a weight coefficient, and when calculating the channel interference reference value result _ ADJ _ RSSI, it is also necessary to consider the signal strength of each channel as ADJ _ RSSIjThe corresponding weighting coefficients. Specifically, if the signal strength of each channel is ADJ _ RSSIjCorresponding weighting coefficient is ajThen, the corresponding channel interference reference value is calculated as follows:
result_ADJ_RSSI＝a1ADJ_RSSI1+a2ADJ_RSSI2+…+a8ADJ_RSSI8，
wherein, a1+a2+…+a8＝1。
Taking 2.4G as an example, for 13 channels (1 channel, 2 channel, … …, 13 channels) of 2.4G, only 1 channel, 6 channel and 13 channel are completely non-interference channels, when calculating the channel interference reference value of 1 channel, the channel signal interference of 2 channel to 5 channel to 1 channel needs to be considered, that is, the channel interference reference value of 1 channel can be calculated by the following formula:
result_ADJ_RSSI＝a2RSSI_ADJ2+a3RSSI_ADJ3+a4RSSI_ADJ4+a5RSSI_ADJ5。
in the present embodiment, the formula result _ ADJ ═ Σ may be usedjajRSSI_ADJj,∑jajThe calculation process of the channel interference reference value is denoted by 1.
Step S106: and calculating a channel quality evaluation value corresponding to the target channel according to the channel interference reference value and the hot spot signal strengths of all WiFi hot spots on the target channel.
In step S104, signal interference of all channels adjacent to the target channel to the WiFi hotspot on the current channel is considered, in this embodiment, not only the channel interference of the adjacent channel but also signal interference between other WiFi hotspots on the same channel need to be considered.
Specifically, the signal strength corresponding to all detected WiFi hotspots of the same channel is considered, which represents the interference of other WiFi hotspots on the same channel to the signal of the current WiFi hotspot.
Specifically, in this embodiment, a specific quantized value of signal interference between WiFi hotspots on the same channel may be a signal interference reference value, and the signal interference reference value may be calculated according to hotspot signal strengths of all WiFi hotspots on the channel.
Specifically, in an embodiment, if there are 5 WiFi hotspots i ═ 1,2, …,5 on the present channel, and the detected hotspot signal strength result _ RSSI of each WiFi hotspot is:
result_RSSI＝RSSI_1+RSSI_2+…+RSSI_5。
that is, the channel interference reference value corresponding to the target channel is obtained by calculating the sum of the hotspot signal strengths of all WiFi hotspots on the target channel as the signal strength sum of the target channel.
In this embodiment, the channel quality evaluation value corresponding to the channel where a WiFi hotspot is located needs to be calculated by considering channel interference on the local channel and channel interference on an adjacent channel, that is, calculating the channel quality evaluation value corresponding to the target channel where the WiFi hotspot is located according to the channel interference reference value on the adjacent channel and the signal interference reference value on the local channel.
Specifically, in an embodiment, the channel quality evaluation value corresponding to a certain channel is equal to the sum of the channel interference reference value of the channel and the signal interference reference value on the channel, that is, the channel quality evaluation value is the channel interference reference value + the signal interference reference value, and may be expressed as:
result_evaluation＝result_RSSI+result_ADJ_RSSI，
wherein, result _ evaluation represents a channel quality evaluation value, result _ RSSI represents a signal interference reference value, and result _ ADJ _ RSSI represents a channel interference reference value.
That is to say, the step of calculating the channel quality evaluation value corresponding to the target channel according to the channel interference reference value and the hotspot signal strengths of all WiFi hotspots on the target channel further includes: calculating the sum of the hot spot signal strengths of all WiFi hot spots on the target channel as the signal strength sum of the target channel; and calculating the channel quality evaluation value corresponding to the target channel according to the signal strength of the target channel and the channel interference reference value corresponding to the target channel.
Step S108: and selecting a WiFi hotspot corresponding to the corresponding hotspot identification to access according to the channel quality evaluation value and the hotspot signal strength.
In this embodiment, the channel quality evaluation values and the hotspot signal strengths of the WiFi hotspots are ranked according to a preset rule, and then an overall optimal WiFi hotspot access is selected.
Specifically, in an embodiment, the step of selecting a WiFi hotspot corresponding to a corresponding hotspot identifier according to the channel quality evaluation value and the hotspot signal strength to access specifically includes: and acquiring a preset second weight coefficient, weighting the hotspot signal strength of the detected WiFi hotspot and the channel quality evaluation value corresponding to the channel where the WiFi hotspot is located according to the second weight coefficient, generating a hotspot evaluation value corresponding to the detected WiFi hotspot, and selecting the corresponding detected WiFi hotspot to access according to the hotspot evaluation value.
Specifically, a weighting coefficient corresponding to the hot spot signal strength RSSI _ OBJ of the detected WiFi hot spot is preset to be α, and a weighting coefficient corresponding to the channel quality evaluation value result _ evaluation corresponding to the channel where the WiFi hot spot is located is β, so that the corresponding calculation formula for calculating the hot spot evaluation value result is as follows:
result＝α·result_evaluation+β·RSSI_OBJ,α+β＝1。
after the hotspot signal strength corresponding to each detected WiFi hotspot and the channel quality evaluation value of the WiFi hotspot are obtained, a hotspot evaluation value corresponding to the WiFi hotspot can be calculated according to the corresponding hotspot signal strength and the channel quality evaluation value, and then a corresponding WiFi hotspot is selected from all detected WiFi hotspots for access according to the hotspot evaluation value of each WiFi hotspot.
As shown in fig. 3, after the hotspot evaluation value corresponding to the detected Wi-Fi hotspot is calculated, a corresponding hotspot evaluation value may be displayed at a position corresponding to a hotspot identifier of the Wi-Fi hotspot in the displayed detected Wi-Fi hotspot list, and the detected Wi-Fi hotspot list may be sorted according to the size of the hotspot evaluation value, and automatically connected to the Wi-Fi hotspot with a better hotspot evaluation value for access. And if the access fails after the specified times of retry failure, the access still fails, and sequentially selecting Wi-Fi hotspots in the Wi-Fi hotspot list according to the size sequence of the hotspot evaluation values to access.
It should be noted that, in this embodiment, in the process of selecting an access WiFi hotspot, the considered factors may include not only the hotspot signal strength and the channel quality of the channel where the WiFi hotspot is located, but also the hotspot quality of the WiFi hotspot, for example, the internet speed and the line drop rate are considered, because the good hotspot signal strength and the channel quality are not equal to the good internet quality and the internet experience.
Specifically, after the step of obtaining the hotspot identification of the detected WiFi hotspot, the hotspot signal strength, and the target channel where the WiFi hotspot is located according to the WiFi signal, the method further includes: acquiring the disconnection rate and/or the average network speed corresponding to the detected WiFi hotspot as a hotspot quality parameter corresponding to the WiFi hotspot; the step of selecting a WiFi hotspot corresponding to a corresponding hotspot identification to access according to the channel quality evaluation value and the signal strength specifically includes: and selecting a WiFi hotspot corresponding to the corresponding hotspot identification to access according to the channel quality evaluation value, the signal strength and the hotspot quality parameter.
After the Wi-Fi connection management program or the hotspot management program obtains hotspot identifications of a plurality of Wi-Fi hotspots in a coverage area and corresponding signal strengths thereof by detecting Wi-Fi signals, the obtained hotspot identifications can be uploaded to a server through a hotspot quality query request, and hotspot quality parameters corresponding to the obtained hotspot identifications stored by the server are queried on the server.
The hotspot quality parameter is parameter information reflecting network access quality of the Wi-Fi hotspot, and can be obtained by detecting the network access quality in the access process and uploading the network access quality to a server for storage by a plurality of intelligent terminals which access the Wi-Fi hotspot historically, or by configuring the server (for example, information such as a charging algorithm or a tariff standard). For example, as shown in fig. 4, if the terminal 1, the terminal 2, and the terminal 3 access the Wi-Fi hotspot a in advance, the terminal 1, the terminal 2, and the terminal 3 upload the network quality parameters in their respective connection states with the Wi-Fi hotspot a to the server, and the server stores the network quality parameters. When the terminal 4 starts to execute the method, detects the Wi-Fi signal, and obtains the hotspot identification of the Wi-Fi hotspot in the area, a hotspot quality query request can be generated according to the obtained hotspot identification (including the hotspot identification of the Wi-Fi hotspot a), and is uploaded to the server, and the server queries the hotspot quality parameters which are uploaded in advance by the terminal 1, the terminal 2 and the terminal 3 and correspond to the hotspot identification of the Wi-Fi hotspot a, and issues the hotspot quality parameters to the terminal 4.
Preferably, the hotspot quality parameter may include at least one of a dropped call rate, an average network speed, or a charging parameter.
The disconnection rate is the probability of disconnection in unit time after the terminal accesses the hotspot, and the lower the disconnection rate is, the more stable the network quality of the Wi-Fi hotspot is, and the lower disconnection rate can bring better experience to the terminal application needing to keep long connection. For example, if a user uses a smart phone to play a network game requiring long connection in a Wi-Fi hotspot, if a drop occurs, the user needs to log in the game again, and a low drop rate can ensure that the user can smoothly play the game.
The average network speed is the average value of the network transmission speed of the terminal in unit time after accessing the hotspot. The higher the average network speed, the faster the data transmission speed. The higher average network speed can facilitate the user to browse the movies and videos with higher resolution on line.
In this embodiment, a preset weighting coefficient may be obtained, a hotspot quality parameter, a channel quality evaluation value, and a signal strength corresponding to a hotspot identifier of a detected WiFi hotspot are weighted according to the weighting coefficient to generate a hotspot evaluation value corresponding to the detected WiFi hotspot, and then a corresponding detected WiFi hotspot is selected for access according to the hotspot evaluation value.
It should be noted that the hot spot quality parameter returned by the server may be a value calculated by the server after weighting, or may be an exact value of the dropped rate and the average network speed, and is automatically generated according to the weighting coefficient after being normalized by the received intelligent terminal.
In addition, in order to solve the technical problem of poor terminal internet access quality caused by the method of selecting a WiFi hotspot access only according to the signal strength of the WiFi hotspot in the conventional technology, in an embodiment, as shown in fig. 5, a device for connecting the WiFi hotspot is further provided, which includes a WiFi signal detection module 102, a channel interference determination module 104, a channel quality evaluation value calculation module 106, and a hotspot access module 108, where:

And selecting the WiFi hotspot needing to be connected finally by combining the signal strength and the channel quality, so that the WiFi hotspot selected to be connected by the intelligent terminal is always the WiFi hotspot with the optimal network quality, and the internet access quality of the intelligent terminal accessing the network is improved.
