Detailed Description
In the prior art, usually, when a terminal device is just connected to a router, or a network of the terminal device changes, for example, when roaming from an Access Point (AP) to another AP, the terminal device performs network connectivity detection to detect whether the terminal device can Access the internet, so as to find a network that cannot Access the internet in time, and prompt a user whether to need to switch to another AP or close a current WIFI connection, so as to save more electric power. The principle of network connectivity detection is mainly to check whether a response is received in time by accessing a network domain name. When the terminal equipment performs WIFI network connectivity detection, when the current network environment of the terminal equipment is complex, the interference is large, the DNS query frame sending or the receiving of the response message is easy to fail, even if the router can surf the internet, the terminal equipment such as a mobile phone is still marked as 'non-internet-capable' mark, the network connectivity detection misjudgment occurs, the accuracy of the network connectivity result is low, and the user experience is influenced.
In the embodiment of the invention, the data packet is analyzed in response to the received network detection starting instruction, when the analysis result shows that the data packet is the DNS message, the transmission priority of the DNS message is increased to the highest sending priority, and the DNS message is sent to the corresponding server according to the highest sending priority, and generally, the higher the priority is, the better the occupation of air interface resources is, the better the reliability of the DNS message in the air interface transmission in a congested environment is promoted, so that the successful sending opportunity is promoted. Therefore, the sending priority of the DNS message is improved, the anti-interference capability of the DNS message can be improved, the success rate of DNS message sending is improved, the misjudgment rate of network connectivity detection can be reduced, and the success rate of the network connectivity detection can be improved.
In order to make the aforementioned objects, features and advantages of the embodiments of the present invention more comprehensible, specific embodiments accompanied with figures are described in detail below.
Referring to fig. 1, a flowchart of a method for detecting WIFI network connectivity of a terminal device in an embodiment of the present invention is shown. The method specifically comprises the following steps:
step S11, in response to the received network probing start instruction, parsing the data packet.
In a specific implementation, the network probe initiation instruction may be generated when the terminal device is just connected to the router, or when the network of the terminal device changes, where the network change may be roaming from one AP to another AP.
In the embodiment of the present invention, the application layer of the terminal device may be used as a network connectivity detection module, and the application layer may be application software APP installed on the terminal device. The application layer may detect a network change, a network access condition, and the like of the terminal device, and generate a network detection start instruction network _ detect _ start _ cmd according to the network access condition and the network change condition. The application layer may issue a network detection start instruction network _ detect _ start _ cmd to the WIFI module. And after receiving the network detection starting instruction, the WIFI module analyzes the received data packet. The data packet is generated by an application layer and is sent to the WIFI module through a network protocol stack.
And step S12, when the analysis result shows that the data packet is a DNS message, the transmission priority of the DNS message is increased to the highest sending priority.
In specific implementation, when the analysis result indicates that the data packet is a Domain Name System (DNS) packet, the sending of the DNS packet is optimized, and the DNS packet is sent preferentially. Wherein, the DNS message carries the domain name to be inquired.
Specifically, the transmission priority of the DNS packet may be increased to the highest transmission priority.
In the embodiment of the present invention, the transmission priority of the DNS packet may be increased to the highest sending priority based on a WIFI Multimedia Quality of Service (WMM Qos) protocol. The WMM is a wireless QoS protocol, which is a subset of the 802.11e protocol, and is used to ensure that a high-priority packet has a priority right to send.
In specific implementation, the transmission priority of the DNS packet is increased to the highest sending priority, which can be implemented as follows: the DNS message is placed in a key frame sending queue of a WIFI Medium Access Control (MAC) link layer, wherein the key frame sending queue has the highest sending priority.
And step S13, sending the DNS message to the corresponding DNS server according to the highest sending priority.
As can be seen from the above, in response to a received network probing start instruction, a data packet is analyzed, and when an analysis result indicates that the data packet is a DNS packet, the transmission priority of the DNS packet is increased to the highest transmission priority, and the DNS packet is transmitted to a corresponding server according to the highest transmission priority. Therefore, the sending priority of the DNS message is improved, the anti-interference capability of the DNS message can be improved, the success rate of DNS message sending is improved, the misjudgment rate of network connectivity detection can be reduced, and the success rate of the network connectivity detection can be improved.
In order to further reduce the misjudgment rate of the network connectivity detection and improve the accuracy of the network connectivity detection, the sending or receiving of the DNS packet may be optimized by at least one of the following methods, specifically:
in an embodiment of the present invention, a DNS query data frame may be configured in advance as a key frame to be added to a software retransmission mechanism, and a retransmission number may also be set.
A hardware retransmission mechanism is usually configured, and if network connectivity detection fails, the network connectivity detection may retransmit the same DNS packet, where the maximum retransmission number is M. The software retransmission mechanism configured in the embodiment of the invention can continue to retransmit on the basis of M times set by hardware retransmission, if the software retransmission is configured to N times, the actual maximum retransmission times is M x N times, and the success rate of sending the DNS message can be further improved by configuring the software retransmission mechanism, so that the misjudgment rate of network connectivity detection is further reduced, and the accuracy of the network connectivity detection is improved.
When the DNS message comprises a DNS query data frame, if the DNS message fails to be sent or a response message corresponding to the DNS message is not received within a set time length, retransmitting the DNS message according to a configured software retransmission mechanism until a set number of times of retransmission or a response message corresponding to the DNS message is received.
In another embodiment of the present invention, an RTS-CTS mechanism is enabled, and based on the RTS-CTS mechanism, the DNS packet is sent to the corresponding DNS server according to the highest sending priority. The RTS-CTS is a request-to-send/clear-to-send protocol, and under an RTS-CTS mechanism, the problem of hiding a terminal can be solved, the influence of other terminals on sending DNS messages or receiving response messages to terminal equipment is avoided, the air interface collision probability of the DNS messages in the sending process is reduced, the misjudgment rate of network connectivity detection is further reduced, and the accuracy of the network connectivity detection is improved.
Specifically, under the RTS-CTS mechanism, the terminal device requests to send a DNS message by sending an RTS request, the DNS server responds to the RTS request with a CTS, and the terminal device may send the DNS message to the DNS server after receiving the CTS. After the terminal device sends the RTS request, the hosts around the terminal device know that there are messages to be sent by the terminal device around the terminal device after receiving the RTS request, and the hosts around the terminal device keep silent without sending any message until the process of sending the DNS message to the DNS server by the terminal device is completely finished. The DNS server responds to the RTS request by using the CTS, the CTS reserves bandwidth for the terminal equipment and simultaneously informs that equipment around all nodes receives messages, the nodes around the DNS server keep a silent state and do not receive and transmit any messages so as to avoid interfering the DNS server to receive the DNS messages until the terminal equipment and the DNS server finish data receiving and transmitting, and the node sides around the DNS server can recover normal data receiving and transmitting.
In another embodiment of the present invention, when the DNS packet is sent to the corresponding DNS server according to the highest sending priority, the DNS packet is in the active state, and after the DNS packet is sent to the corresponding DNS server according to the highest sending priority, the active state is maintained to receive a response packet corresponding to the DNS packet, and the response packet is fed back by the DNS server according to the DNS packet.
By maintaining an active state, the terminal equipment can be prevented from entering a dormant state, so that the terminal equipment can receive a response message fed back by the DNS server in time.
In another embodiment of the present invention, the lowest basic rate supported by the terminal device is adopted, and the DNS packet is sent to the corresponding DNS server according to the highest sending priority.
In specific implementation, data with the same size is transmitted, the lower the transmission rate is, the longer the occupied space time is, and the higher the transmission success rate is, so that the DNS message is transmitted at the lowest basic speed supported by the terminal equipment according to the highest transmission priority, the anti-interference capability of the DNS message can be improved, and the probability of successful transmission is improved.
The research finds that another reason for misjudgment of network connectivity detection is that the number of DNS query domains is usually fixed to one or two, and when DNS packets are generated for one or two domains that are fixedly set, because different users are distributed in different countries, domain access may be limited, so that when network connectivity detection is performed for only fixed domains, the network connectivity detection result fails, and a "non-internet-capable" identifier is marked, and in practice, a router is capable of accessing the internet, so that the accuracy of the network connectivity detection result is low.
In order to further improve the accuracy of the network connectivity detection result, in the embodiment of the present invention, the DNS message is generated in the following manner: when detecting that WIFI network connectivity detection is triggered, acquiring a preset domain name list, wherein a plurality of different domain names are recorded in the domain name list; inquiring the domain name from the domain name list, and taking the inquired domain name as the domain name to be inquired; and generating the DNS message according to the domain name to be queried. The number of the domain names in the domain name list can be as many as 20-30 or more, and the domain names in the domain name list can be distributed in mainstream famous domain name systems all over the world, so that the probability of limited domain name access can be effectively reduced, and the probability of receiving a response message corresponding to a DNS message generated aiming at a certain domain name is improved.
In specific implementation, when a response message corresponding to the DNS message is not received within a set duration, it is determined that network connectivity detection for the DNS message fails, a domain name may be continuously queried from a domain name list, the queried domain name is used as a domain name to be queried, a corresponding DNS message is generated according to the domain name to be queried, and WIFI network connectivity detection is continuously performed until a response message corresponding to one of the DNS messages is received within the set duration or query of all domain names in the domain name list is completed.
When the domain name is queried from the domain name list, the current position of the terminal device can be obtained, the domain name corresponding to the current position is queried from the domain name list according to the current position, and the domain name corresponding to the current position is used as the domain name to be queried.
For example, the current location of the terminal device is china, and a chinese domain name is queried from the domain name list as a domain name to be queried. For another example, the current location of the terminal device is the united states, and the united states domain name is queried from the domain name list as the domain name to be queried.
The domain name corresponding to the current position is preferentially acquired for network connectivity detection, so that the probability of access limitation caused by the position can be effectively reduced, the probability of successful domain name access is improved, and the efficiency of network connectivity detection is improved.
It is understood that the domain name query can also be performed one by one according to the rank order of each domain name in the domain name list.
When network connectivity detection is triggered, corresponding DNS messages are generated one by one according to domain names in a domain name list, the generated DNS messages are sent to a DNS server corresponding to the domain name, and the domain names are accessed one by one to perform network connectivity detection.
In specific implementation, when a response message corresponding to the DNS message corresponding to the last domain name in the domain name list is not received within a set time length, it may be determined that the detection of the connectivity of the WIFI network fails. When the WIFI network connectivity detection is judged to fail, an internet access unavailable identifier can be set. The non-network-enabled identification may be various, such as, for example, the non-network-enabled identification being "! "or" x ", etc., it being understood that other designations may be used.
In specific implementation, the domain names in the domain name list can be updated regularly to remove the failed domain names or add new domain names, so as to reduce the influence of domain name failure or access limitation and the like on domain name access, and to facilitate improving the network connectivity detection efficiency or reducing the network connectivity detection misjudgment rate during subsequent network connectivity detection.
In specific implementation, the configuration of the domain names and the number of domain names contained in the domain name list, the generation of the DNS packet, and the like may be implemented by an application layer of the terminal device.
In a specific implementation, after receiving the network probing termination instruction, the parsing of the data packet may be terminated.
Upon completion of the network connectivity check, a network probe end instruction may be generated. The completing of the network connectivity detection may include receiving a response message corresponding to the DNS message, or failing to detect the network connectivity. And when a response message corresponding to the DNS message is received, judging that the network is connected. When the network connectivity is determined, the network connectivity detection may be ended.
When detecting that the network connectivity detection is completed, the application layer of the terminal device generates a network detection end instruction network _ detect _ end _ cmd, and sends the network detection end instruction network _ detect _ end _ cmd to the WIFI module, and after receiving the network detection end instruction network _ detect _ end _ cmd, the WIFI module stops analyzing the data packet.
In specific implementation, after the WIFI module exits the analysis of the data packet, the WIFI module may be allowed to enter a sleep (doze) state according to the current WIFI status.
In order to facilitate better understanding and implementation of the embodiment of the present invention for those skilled in the art, referring to fig. 2, another method for detecting WIFI network connectivity of a terminal device in the embodiment of the present invention is provided, which specifically includes the following steps:

Step S203, issuing DNS messages one by one according to the domain name list, wherein the DNS messages comprise DNS query data frames.
Step S204, the WIFI module starts to detect whether the message sent by the network protocol stack is a DNS query data frame.
In step S205, the WIFI module detects a DNS query data frame.
And step S206, carrying out optimized sending and receiving processing of a WIFI link layer.
The optimized sending and receiving processing of the WIFI link layer may include at least one of the following: adding the DNS query frame as a key frame into a software retransmission mechanism; enabling an RTS-CTS mechanism, and sending the DNS message to a corresponding DNS server according to the highest sending priority based on the RTS-CTS mechanism; maintaining an active state to receive a response message corresponding to the DNS message; sending the DNS message to a corresponding DNS server according to the highest sending priority by adopting the lowest basic rate supported by the terminal equipment; the description in the above embodiments of the present invention may be specifically referred to, and details are not repeated here.
