In the prior art, although the development of electronic devices and network technologies is rapid, a phenomenon that a WIFI network is abnormal still often occurs when a user uses a mobile phone, which includes various situations that the WIFI connection is disconnected and the WIFI connection is not disconnected but the internet cannot be connected, in order to solve the problem, a general method adopted in the prior art is to pre-install gms for devices such as terminal devices and the like which can be connected with the WIFI network, automatically detect the connection state of the WIFI network through the gms algorithm, and automatically switch the WIFI network when the WIFI network connection is abnormal. However, not all terminal devices such as mobile phone devices are pre-equipped with gms, and for a mobile phone without the pre-equipped gms, when the WIFI network is connected but the mobile phone cannot surf the internet, the mobile phone cannot automatically detect whether the WIFI network is abnormal, and then automatically adjust the WIFI connection state. And for the device with the pre-installed gms, the problem of untimely or non-detection often occurs due to the defect of the algorithm, and the device cannot access the internet.
In order to solve the above problems, embodiments of the present invention provide a WIFI connectivity detection method, according to the WIFI connectivity detection method of this embodiment, a terminal device obtains network detection data of a terminal device node according to a predetermined time frequency, determines whether the network detection data meets a preset condition, determines that a WIFI connection state of a current terminal device is abnormal when the network detection data meets the preset condition, performs connectivity detection on a WIFI network, and searches for another available WIFI network again for connection when the WIFI network is abnormal. The problem that for a terminal device without pre-installed gms, when the WIFI is connected but the Internet cannot be accessed, the terminal device cannot automatically detect whether the WIFI network is abnormal or not is solved, and for the device with the pre-installed gms, the problem that the device cannot access the Internet due to the fact that detection is not timely or not performed frequently occurs due to the defect of an algorithm is solved.
Exemplary method
As shown in fig. 1, an embodiment of the present invention provides a WIFI connectivity detection method, which may be used for terminal devices such as terminal devices that can connect to a WIFI network. The method in the embodiment of the invention comprises the following steps:
s100, controlling monitoring and repeatedly acquiring network detection data;
wherein before the step of controlling to repeatedly obtain network test data comprises:
presetting a preset condition for judging whether connectivity detection is needed, and judging whether the connectivity detection is carried out on the WIFI network when the network detection data meet the preset condition;
in this embodiment, a preset condition for judging whether the WIFI network is abnormal is set, and the preset condition is compared with network detection data acquired by the terminal device, where the preset condition represents that the WIFI network may be abnormal when the network detection data acquired by the terminal device meets the preset condition. Therefore, the preset condition is not a fixed value, is an empirical value with a certain rule and range, can be a condition which is most suitable for the terminal device and is obtained by a developer through a large amount of data verification, and can also be a value which is obtained by repeatedly acquiring network detection data and judging possible abnormity of the WIFI network and combining actual connectivity detection and correction of the WIFI network by the terminal device.
For example, it is verified according to experience data of a developer that, when an acquisition interval is two seconds, if it is determined that the WIFI network of the terminal device is abnormal when three consecutive times of acquiring tcp receive messages, that is, tcp rx is 0, or ten consecutive times of acquiring tcp send messages, that is, tcp tx is 0, the network detection data acquired by the terminal device is tcp receive messages and tcp send messages, and when the above conditions are met, the terminal device controls to perform connectivity detection on the WIFI network. The tcp receiving message and the tcp sending message are communication information between the terminal device and the internet after the terminal device is connected with the WIFI network, wherein the tcp receiving message is information sent to the terminal device by the internet, and the tcp sending message is information sent to the internet by the terminal device.
For example, according to a correction process in which the terminal device obtains the preset condition by repeatedly acquiring the network detection data and combining the actual WIFI connectivity detection result, when it is continuously determined that the WIFI network is possibly abnormal for many times but the WIFI network is found to be normal through the connectivity detection of the actual WIFI network, the trigger threshold of the network detection data is correspondingly increased, for example, the acquisition frequency of the terminal device is once every two seconds, and when the tcp received packet number tcp rx of three consecutive times is 0, the WIFI connectivity detection is performed, and when the tcp received packet number tcp rx of four consecutive times is 0, the trigger threshold of the network detection data is correspondingly increased, the WIFI connectivity detection is performed. The automatic adjustment detection method can further reduce the number of times of WIFI connectivity detection, reduce the power consumption of the terminal equipment and provide more accurate judgment of the WIFI network connection state for the user.
Wherein the preset conditions include: and judging a first preset condition of the abnormal state of the network connection through the message receiving number tcp and judging a second preset condition of the abnormal state of the network connection through the tcp information.
Specifically, the first preset condition is that when the number of tcp message receiving messages and the number of tcp message sending messages which are continuously obtained both indicate that the number of times that the terminal device does not generate message interaction with the network reaches a preset number of times, it is determined that the WIFI network connection is abnormal.
For example, when the tcp message receiving number tcp rx is 0 and the tcp message sending number tcp tx is 0, it represents that the terminal device does not interact with the network, at this time, the terminal device may not use a process that needs to interact with the network, or at this time, it does not need to interact with the network, but represents that the connection between the terminal device and the network is abnormal at this time, a preset number of times is set, and when the tcp message receiving number and the tcp message sending number that are continuously read by the terminal device are always zero and reach the preset number of times, it is determined that the WIFI network is possibly abnormal.
And the second preset condition is that the WIFI network connection abnormity is judged when the number of tcp connection abnormity exceeds the preset proportion of total tcp connection. And judging that the tcp connection is abnormal through tcp information including any one parameter of a tcp state, a retransmission number and a reply time exceeding a preset value. The tcp state comprises a plurality of states such as closed, listen, syn _ rcvd, syn _ sent and the like, and is used for representing the current working mode of tcp connection, the retransmission number is that the tcp connection is in the data transmission process, the other party can resend a transmission data packet if the other party does not receive complete information transmitted by the tcp, the tcp connection is judged to be possibly abnormal when continuous multiple transmission fails, the reply time is that the tcp connection starts a timer after transmitting one data, and whether the reply time of the tcp connection exceeds the preset time length or not can be used as one of the indexes for judging the tcp connection abnormity when the time of the timer recorded after receiving an ack confirmation message transmitted by the other party is received.
For example, when the reply time that the terminal can acquire a certain tcp connection is longer than ten seconds, it is determined that the tcp connection is abnormal, and when another tcp connection state is acquired as closed, it may also be determined that the tcp connection is abnormal, and when it is detected that the number of tcp connections with tcp connection abnormality exceeds 80% of the total number of tcp connections, it is determined that the current WIFI network connection is abnormal.
The method for judging the WIFI network connection abnormity through multiple judging modes can enable the judging result to be more stable, and when one judging mode fails or when the first judging result is unstable, the second judging mode can be used for replacing the judging mode. For example, when tcp rx and tcp tx are used for judgment, if the difference between the judgment result and the WIFI network connectivity detection result is large in a short time, the first judgment mode is controlled to be closed, so that the terminal device can freely select a more accurate judgment mode for judgment, and the power consumption of the terminal device is reduced.
Step S200, comparing the acquired network detection data with preset conditions, and judging whether the network detection data meet the preset conditions;
in this embodiment, after the terminal device obtains network detection data of the terminal device according to a predetermined time frequency or time interval, the network detection data includes a tcp packet number and a ratio of the number of tcp connection anomalies, and the ratio of the number of tcp connection anomalies is determined by a tcp state, a retransmission number, and a reply time in tcp information. And comparing the acquired network detection data with preset conditions, including a first preset condition and a second preset condition, and judging whether the network detection data meets the preset conditions.
For example, the acquired network detection data includes the number of tcp received messages and the number of tcp sent messages, and the first preset condition set in the mobile phone is that when it is determined that the number of tcp received messages of the mobile phone lasts five times and is less than one, the number of tcp sent messages is greater than or equal to zero or the number of tcp received messages of the mobile phone lasts three times and is equal to zero, and it is determined that the WIFI connection is abnormal. If the first time tcp rx is 0, tcp tx is 1, the second time tcp rx is 0, tcp tx is 5, the third time tcp rx is 1, tcp tx is 0, the number of tcp packets at the first three times does not satisfy the first preset condition because the third time tcp rx is 1; and if the fourth time tcp rx is 0, the tcp tx is 2, the fifth time tcp rx is 0, the tcp tx is 1, the sixth time tcp rx is 0, and the tcp tx is 0, the tcp packet number at the last three times is determined to satisfy the first preset condition.
When a user uses a mobile phone, the obtained network detection data comprises network detection data such as tcp states, retransmission numbers and response time for representing whether each tcp connection is abnormal, and the tcp connection is judged to be abnormal when the tcp states are closed or the tcp retransmission numbers are more than six times or the response time exceeds ten seconds in a first preset condition, and the WIFI network connection is judged to be abnormal when the tcp connection exceeding 70% is judged to be abnormal. Then, when the tcp connection number of the first time tcp state is 50% of closed tcp connections, the tcp connection number of the tcp retransmission number is 30% of tcp connections with more than six times, and the tcp connection number of the reply time exceeding 10 seconds is 50%, assuming that the result of the ratio of tcp connection abnormality obtained by simultaneous judgment of the three parameters is 87%, then the WIFI network connection abnormality is judged at the current time.
Further, screen on-off judgment can be added, when a user uses the mobile phone, the screen is basically in a screen on state, the requirement on the network real-time performance of the mobile phone in the state is high, so that the preset time frequency is accelerated correspondingly, on the contrary, when the screen is off, the user has a high probability of not using the mobile phone, or when the screen is off, whether screen off applications such as internet clouds and the like which can be used are running is further judged, when the user is judged not to use the mobile phone, the requirement on the network real-time performance of the mobile phone in the state is low, the time frequency for acquiring network detection data can be correspondingly reduced, the power consumption is further reduced, and the user experience is improved.
Further, in step S300, when it is determined that the acquired network detection data meets the preset condition, connectivity detection is performed on the WIFI network.
In this embodiment, when it is determined that the acquired network detection data meets the preset conditions, including the first preset condition and/or the second preset condition, connectivity detection is performed on the WIFI network.
The connectivity detection is that a specified access request capable of accessing across domains is sent to a public network server through terminal equipment, and if the equipment receives a response message of the specified access request within a preset time length, the network connectivity with the public network server is determined, and if the equipment does not receive the response message of the specified access request within the preset time length, the network connectivity with the public network server is determined.
When the WIFI network is confirmed to be normal, the original WIFI connection is kept, and when the WIFI network is confirmed to be abnormal, the connectable WIFI network is rescanned and the WIFI network connection is switched.
As shown in fig. 2, according to experimental results, it is shown that by using the method, not only can a terminal device without the premounted gms automatically determine whether the WIFI network is abnormal, but also the speed and accuracy of WIFI network switching can be further improved by comparing the terminal device with the premounted gms.
Further, as shown in fig. 3, a second embodiment shows a software implementation scheme of the WIFI connectivity detection method, which includes the steps of:
step S10, starting, opening a switch of the WIFI connectivity detection function through the apk, and entering step S11;
step S11, the Framework layer Framework issues a WIFI connection or disconnection message to a network daemon (net), and the step S12 is entered;
step S12, the network daemon (net) transmits the frame layer information to a real-time operating system kernel through a socket, and the step S13 is entered;
step S13, the real-time operating system kernel counts the number of tcp messages which are matched with the wlan0 and flow through the protocol stack through a hook function, writes the tcp messages into the equipment node, and enters step S14;
step S14, the WIFI service reads the statistical result in the equipment node, judges whether WIFI connectivity detection is needed or not through a detection algorithm, and enters step S15 when the WIFI connectivity detection is needed;
step S15, performing connectivity detection through a WIFI connectivity detection algorithm (evaluation algorithm) WIFI network, and ending.
As can be seen from the above, in the embodiment of the present invention, a user can also determine whether the WIFI network is abnormal in real time through the number of tcp messages flowing through the protocol stack by software and an algorithm without using gms, and when it is determined that the WIFI network is possibly abnormal, further confirm whether the WIFI network is abnormal through WIFI connectivity detection.
