Detailed Description
The technical scheme of the application is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a schematic flowchart of a wireless network detection method according to an embodiment of the present disclosure, where the method may be executed by a wireless network detection apparatus, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in a terminal device such as a mobile phone, a tablet computer, and a computer. As shown in fig. 1, the method includes:
And the common data frame comprises a common data frame interacted between a second terminal and a wireless hotspot in the wireless local area network.
For example, specific types of the first terminal and the second terminal in the embodiment of the present application are not limited in the embodiment of the present application, and both the first terminal and the second terminal may be a mobile terminal or a fixed terminal, and one of the first terminal and the second terminal may also be a mobile terminal and one of the fixed terminal may be a fixed terminal, where the mobile terminal is a mobile phone, a tablet computer, or the like, and the fixed terminal is a desktop computer, or the like. In this embodiment, for example, the above-mentioned wireless network detection apparatus is integrated in the first terminal, the second terminal may be any other terminal in the wireless lan where the first terminal is located, and the first terminal and the second terminal may be collectively referred to as a terminal.
The wireless local area network in the embodiment of the application can be a wireless network corresponding to wireless network signals sent by a wireless router, a computer, a portable wireless fidelity WiFi or other wireless network hotspots and the like. The terminal can access the internet by opening a wireless network connection function, scanning nearby wireless hotspots and connecting the wireless hotspots. When a user uses a terminal, the situation that the user cannot access the internet (or called as surfing) may occur, and the specific reason for the situation that the terminal cannot know the situation may be that the currently connected wireless hotspot cannot access the internet, or the terminal cannot access the internet due to a problem. If the terminal cannot access the internet due to the terminal itself and the wireless hotspot is not abnormal, other normally operating terminals in the same wireless lan can access the internet, however, in the related art, the current terminal cannot know whether other terminals can access the internet because the terminal only receives and processes a unicast frame with a destination address matching with its own address information or a broadcast or multicast frame in the wireless lan, and therefore cannot know whether other terminals connected to the current wireless hotspot can access the internet.
In the embodiment of the application, when the first terminal receives the data frame of which the destination address is not matched with the address information of the first terminal, the first terminal cannot directly discard the data frame. For a normal data Frame (generic Frame) that interacts between the second terminal and the wireless hotspot within the wireless local area network, the first terminal is not directly discarded, but is received and used for subsequent analysis. In the wlan standard protocol (e.g. 802.11), the main frame types include management frames, control frames, and data frames, the management frames include, for example, Beacon frames (Beacon), Probe Request frames (Probe Request), Probe Response frames (Probe Response), and Authentication frames (Authentication), the control frames include Request frames, permission frames, and Response frames, and the data frames mainly include handshake data frames and normal data frames. The common data frame interacted between the second terminal and the wireless hotspot in the wireless local area network comprises the related information of the second terminal accessing the network.
In the embodiment of the application, step 101 may be executed after detecting that the first terminal is connected to the wireless hotspot, and the determination result in step 103 is recorded; step 101 may also be performed after detecting that the first terminal has no access to the internet.
And 102, acquiring a source IP address from the common data frame.
For a wireless hotspot, the connection of a terminal which cannot input a password correctly can be limited by setting the password; or the password is not set, so that the terminals needing to be connected can share the wireless hotspot. In this embodiment, the source IP address when the second terminal accesses the network is obtained from the obtained common data frame, where the network may include a wireless local area network or the internet, and the source IP address is an IP address corresponding to a network that sends a data packet to the second terminal. When the wireless hotspot is not provided with the password, the common data frame is not encrypted, and the source IP address can be directly extracted from the common data frame. Typically, the source IP address is contained in an IP datagram. When the wireless hotspot sets the password, the common data frame is encrypted, the common data frame needs to be decrypted, and then the source IP address is extracted.
And 103, judging whether the source IP address is from the outside of the wireless local area network, and determining the reason why the first terminal cannot access the Internet according to the judgment result.
For example, the source IP address may be compared with the IP address of the first terminal itself, so as to determine whether the terminal sending the data packet to the second terminal and the first terminal are in the same lan, and if not, the source IP address may be considered to be from outside the wlan. When the source IP address is from outside the wireless lan, it can be stated that the second terminal can access the internet, so the wireless hotspot can access the internet, and the reason that the first terminal cannot access the internet appears at the first terminal side, which may be that the first terminal itself is abnormal, or the wireless connection between the first terminal and the wireless hotspot is abnormal.
The wireless network detection method provided in the embodiment of the application obtains the common data frame interacted between other terminals and the wireless hotspot in the wireless local area network where the terminal is located, obtains the source IP address from the common data frame, judges whether the source IP address is from outside the wireless local area network, and determines the reason why the terminal cannot access the internet according to the judgment result. By adopting the technical scheme, the reason that the terminal cannot access the internet can be analyzed, the wireless network detection function of the terminal is enriched, and a user can take corresponding measures conveniently according to the analysis result.
In some embodiments, before the acquiring the normal data frame transmitted in the wireless local area network in which the first terminal is located, the method may further include: acquiring handshake data frames transmitted in the wireless local area network, wherein the handshake data frames comprise handshake data frames interacted between the second terminal and the wireless hotspot; and acquiring a target key from the handshake data frame, wherein the target key is used for decrypting the common data frame. The obtaining a source internet protocol IP address from the common data frame includes: and acquiring a source IP address from the common data frame according to the target key. The advantage of such an arrangement is that when the wireless hotspot sets the password, the target key can be obtained by acquiring the data in the handshake data frame, and the common data frame is decrypted by using the target key, so that the source IP address can be quickly obtained.
When the wireless hotspot sets the password, authentication is needed between the wireless hotspot and the terminal, and generally through a handshake mode. Taking WiFi as an example, encryption is generally performed in a wireless fidelity network secure Access (WPA) manner, and authentication manners are mainly WPA-PSK and WPA2-PSK, where PSK is a pre-shared Key mode (also referred to as a personal mode), authentication may be performed specifically by using four-way handshake, and the four-way handshake generates a Pairwise Transmission Key (PTK) from a Pairwise Master Key (PMK) through a series of interactions, and when a wireless local area network is a WiFi network, the PTK is a target Key described in this embodiment of the present application. Data transmitted between the WiFi hotspot and the terminal in the wireless local area network may be encrypted by the PTK. The generation of PTK requires 5 essential elements: PMK, ANonce (Nonce1), SNonce (Nonce2), authentication MAC (MAC1), and supplementary MAC (MAC2), wherein PMK is pre-agreed between WiFi hotspots and terminals, authentication represents WiFi hotspots, also called Access Points (APs), supplementary is terminals connected to WiFi hotspots, Nonce1 is a random number generated by WiFi hotspots, Nonce2 is a random number generated by terminals, and MAC represents a Media Access Control (Media Access Control) address, also called a physical address or a hardware address. In the process of four-way handshake, the WiFi hotspot will send Nonce1 and its MAC address to the terminal by sending handshake data frame, and the terminal will also send Nonce2 and its MAC address to the WiFi hotspot by sending handshake data frame. In the embodiment of the present application, the handshake data frame interacted between the second terminal and the wireless hotspot is obtained, that is, the address information of the second terminal (the MAC address of the second terminal, i.e., the MAC2 mentioned above) and the Nonce1, Nonce2, and MAC1 for generating the PTK are obtained from the handshake data frame, and since the first terminal knows the password for connecting the WiFi hotspot, the PMK can also be obtained, and therefore, the PTK between the WiFi hotspot and the second terminal can be generated.
In some embodiments, the source IP address may be included in an IP datagram, the obtaining the source IP address from the normal data frame according to the destination key comprises: decrypting the common data frame according to the target key to obtain an IP datagram; and acquiring a source IP address from the IP datagram. The IP source address is generally contained in the header of the IP datagram, and can be read from the corresponding data bit according to the format of the IP datagram, so that the reading process is quick and accurate.
In some embodiments, it may further include: and if the handshake data frame transmitted in the wireless local area network is not successfully acquired, notifying the second terminal to reconnect the wireless hotspot, and acquiring the handshake data frame transmitted in the wireless local area network again. This has the advantage that successful acquisition of the handshake data frame can be guaranteed. For example, if the first terminal is the last terminal that joins the wireless lan, the handshake data frame exchanged between the other terminals and the wireless hotspot may not be obtained, at this time, the second terminal may be notified to disconnect from the wireless hotspot and reconnect, a handshake data frame may be generated in the process of reconnection, and at this time, the first terminal may obtain the handshake data frame again. Optionally, it may be detected whether a terminal in bluetooth connection with the first terminal exists in the current wireless lan, and if so, the terminal is used as the second terminal to notify the second terminal of reconnecting the wireless hotspot; and if the Bluetooth connection does not exist, automatically establishing the Bluetooth connection with the second terminal in the wireless local area network, and informing the second terminal to reconnect the wireless hotspot.
In some embodiments, determining whether the source IP address is from outside the wireless local area network may include: performing bit AND operation on the IP address of the first terminal and the subnet mask of the wireless local area network to obtain a first operation result; performing bit AND operation on the source IP address and the subnet mask of the wireless local area network to obtain a second operation result; and judging whether the first operation result is matched with the second operation result, and if not, determining that the source IP address is from the outside of the wireless local area network. The advantage of this arrangement is that it can quickly and accurately determine whether the source IP address is from outside the wireless lan. For example, the IP address of the first terminal, the subnet mask of the wireless lan, and the source IP address may be first converted into binary data, and then a corresponding and operation may be performed.
In some embodiments, the determining, according to the determination result, a reason why the first terminal cannot access the internet includes: and when the source IP address comes from the outside of the wireless local area network, determining that the first terminal side is abnormal. When the source IP address is from outside the wireless lan, it indicates that the second terminal can successfully access the internet, and the reason that the first terminal cannot access the internet appears at the first terminal side, which may be that the first terminal itself is abnormal, or the wireless connection between the first terminal and the wireless hotspot is abnormal. Optionally, if it is determined that the first terminal side is abnormal, the first terminal may be controlled to perform a corresponding first prompting operation, such as prompting a user to approach the first terminal to a wireless hotspot, or reconnecting the first terminal to the wireless hotspot, or restarting the wireless network connection module. Optionally, the first terminal may also automatically perform a corresponding recovery operation, for example, the first terminal automatically reconnects the wireless hotspot, or the first terminal automatically restarts the wireless network connection module, and the like.
Further, the determining, according to the determination result, the reason why the first terminal cannot access the internet further includes: and if the common data frame of which the source IP address is from the outside of the wireless network is not acquired within the preset time, determining that the wireless hotspot side is abnormal. The preset duration may be set according to an actual situation, for example, according to the signal strength of the wireless hotspot detected by the first terminal. For example, the preset time period may be set to 10 minutes. If the common data frame with the source IP address from the outside of the wireless network is acquired within the preset time, it indicates that other terminals in the wireless network cannot normally access the internet, and it can be determined that the wireless hotspot side is abnormal, and may be that the wireless router is abnormal, or the broadband fails, etc. If the wireless hotspot side is judged to be abnormal, the first terminal can be controlled to perform corresponding second reminding operation, such as prompting a user to check whether the router or the broadband is normal.

For example, the terminal a in the embodiment of the present application may be understood as the above first terminal, and the terminal B may be understood as the above second terminal.
It is understood that when step 203 is executed again, terminal B may be replaced by other terminals in the wlan, such as terminal C, terminal D, and terminal E.
And step 204, acquiring the source IP address from the common data frame.
And 208, determining that the source IP address is from the outside of the wireless local area network, and controlling the terminal A to remind the user to reconnect the WiFi hotspot when the terminal A side is abnormal.
The wireless network detection method provided by the embodiment of the application is suitable for the situation that a WiFi hotspot is not encrypted, when a terminal connected with the WiFi hotspot cannot access the Internet, whether other terminals can access the Internet or not can be analyzed by analyzing common data frames transmitted between other terminals and the WiFi hotspot, and then the reason that the terminal cannot access the Internet is determined, more accurate and more effective reminding can be provided for a user, the wireless network detection function of the terminal is enriched, and the terminal is more intelligent.
Fig. 3 is a schematic flowchart of another wireless network detection method provided in the embodiment of the present application, which is described by taking an encrypted WiFi hotspot as an example, and includes the following steps:
For example, the terminal a in the embodiment of the present application may be understood as the above first terminal, and the terminal B may be understood as the above second terminal.
And step 303, detecting that the terminal A cannot access the Internet.
And step 304, acquiring a common data frame interacted between the terminal B and the WiFi hotspot in the wireless local area network.
It is understood that when step 304 is executed again, terminal B may be replaced by other terminals in the wlan, such as terminal C, terminal D, and terminal E.
And 305, decrypting the common data frame by using the PTK to obtain an IP datagram, and reading a source IP address from the IP datagram.
307, judging whether the time length that the terminal A cannot access the Internet reaches the preset time length or not, if so, executing a step 308; otherwise, return to execute step 304.
The wireless network detection method provided by the embodiment of the application is applicable to the situation of WiFi hotspot encryption, the handshake data frames transmitted between other terminals and the WiFi hotspot can be obtained firstly, the key PTK for decrypting the common data frame is obtained, when the terminal connected with the WiFi hotspot cannot access the Internet, whether the other terminals can access the Internet or not can be analyzed by analyzing the common data frames transmitted between the other terminals and the WiFi hotspot, the reason that the terminal cannot access the Internet is further determined, more accurate and more effective reminding can be provided for a user, the wireless network detection function of the terminal is enriched, and the terminal is more intelligent.
Optionally, in some embodiments, after the terminal is connected to the WiFi hotspot, the terminal may obtain a data frame in real time, where the data frame includes data frames transmitted between all terminals in the wireless local area network and the WiFi hotspot, and determine whether a target address of the data frame is an MAC address of the terminal, and if not, the target address is not directly discarded, but the type of the data frame is determined. It is determined whether the data frame is a four-way handshake frame or a normal data frame. Illustratively, whether it is a frame of a four-way handshake or a normal data frame may be distinguished by a protocol field of the data frame. For example, the Protocol field in the frame of the four-way handshake may be "Protocol: 802.1X Authentication (0X888 e)", the Protocol field of the normal IP data frame may be "Protocol: IPv4(0X 0800)", and it can be seen that the value of the Protocol field of the frame of the four-way handshake is 0X888e, and the value of the Protocol field of the normal data frame is 0X 0800. If the frame is a frame of four-time handshake, the MAC address of the terminal performing the four-time handshake and the generated secret key are saved; and if the data frame is the common data frame, finding the secret key corresponding to the MAC address of the terminal stored before according to the MAC address corresponding to the common data frame, and decrypting the data frame to obtain the decrypted IP datagram. For unencrypted hotspots, unencrypted IP datagrams can be extracted directly from the received data frames. Judging whether the source IP address (supposed to be marked as IP1) of the obtained IP datagram is from an external network, if the IP address and the IP1 of the terminal are respectively subjected to 'bit AND operation' with the subnet mask of the WLAN, if the operated results are different, the IP1 does not belong to the local area network, and if the IP datagram is from the external network, the terminal equipment is considered to be capable of accessing the Internet, and the result is recorded. When the terminal device cannot access the internet, whether only the terminal cannot access the internet can be known by inquiring the recorded result before, and then the terminal can be subjected to targeted prompt (for example, if only the terminal cannot access the internet, a user is prompted to be close to a hot spot or to reconnect WiFi, and if other terminals cannot access the internet, the user is prompted to check whether a router and a broadband are normal). Optionally, when a result recorded before querying is performed, the record of the time interval from the current moment in the preset time interval may be selected, so as to ensure the accuracy of the analysis result for the current terminal that cannot surf the internet.
