[0002] With the development of Internet of Things technology, a large number of WIFI IoT devices have entered people's lives. The use scenario system of IoT devices mainly includes WIFI modules, routers, cloud and user terminals (such as mobile phones, etc.).

[0028] In this embodiment, a method for determining a disconnection reason is provided, which is applied to a computer terminal. Figure 2 : is a flowchart of a method for determining a disconnection cause according to an embodiment of the present application, the process comprising the following steps:

[0029] Step S202: When it is determined that the target device is disconnected from the first wireless access point, an access request is sent to a second wireless access point with the same name as the first wireless access point;

[0030] It should be noted that the first wireless access point and the second wireless access point may be routers.

[0031] Step S204: when the second wireless access point responds to the access request so that the second wireless access point establishes a connection with the target device, receiving frame data sent by the second wireless access point, wherein the frame data includes: a first physical address of the second wireless access point and a first working duration of the second wireless access point;

[0032] It should be noted that when the router is working normally, it will periodically send 802.11 Beacon frames. The Timestamp in the Beacon frame is used to indicate the time (in microseconds) that the router has been working. The target device can receive the Beacon frame sent by the router. When the router is powered on or restarted, the Timestamp of the Beacon frame will be accumulated from 0. The rollback of the Timestamp of the Beacon frame means that the Timestamp of the Beacon frame becomes smaller. Therefore, you can determine whether the router has been restarted by comparing whether the Timestamps of the two received Beacon frames have rolled back.

[0033] Step S206, determining a similarity between the first physical address and the second physical address of the first wireless access point, and determining a first time difference between a connection time and a disconnection time, wherein the connection time is used to indicate a time when the target device establishes a connection with the second wireless access point, and the disconnection time is used to indicate a time when the target device disconnects from the first wireless access point;

[0034] Step S208: determining a disconnection reason between the target device and the first wireless access point according to the similarity, the first time difference and the first working duration.

[0035] Through the above steps, when it is determined that the target device is disconnected from the first wireless access point, an access request is sent to a second wireless access point with the same name as the first wireless access point; when the second wireless access point responds to the access request so that the second wireless access point establishes a connection with the target device, frame data sent by the second wireless access point is received, wherein the frame data includes: a first physical address of the second wireless access point and a first working time of the second wireless access point; similarity between the first physical address and the second physical address of the first wireless access point is determined, and a first time difference between a connection time and a disconnection time is determined, wherein the connection time is used to indicate whether the target device has established a connection with the second wireless access point. The disconnection time is used to indicate the time when the target device is disconnected from the first wireless access point; the disconnection reason between the target device and the first wireless access point is determined according to the similarity, the first time difference and the first working time, which solves the problem that the disconnection reason between the WIFI device and the router can only be determined through user participation in the related art. In the embodiment of the present invention, the disconnection reason between the target device and the wireless access point is determined through the similarity between the first physical address of the second wireless access point and the second physical address of the first wireless access point, the first time difference between the connection time and the disconnection time, and the working time of the second wireless access point, without manual participation, and the disconnection reason between the target device and the wireless access point can be automatically and accurately determined.

[0036] In an exemplary embodiment, the above step S208 can be implemented by the following steps:

[0037] Step 1: Determine a first magnitude relationship between the similarity and a first preset threshold;

[0038] It can be understood that the first preset threshold is 100%, that is, whether the first physical address is consistent with the second physical address is determined according to the similarity between the first physical address of the second wireless access point and the second physical address of the first wireless access point, and then whether the second wireless access point and the first wireless access point are the same wireless access point is determined.

[0039] Step 2: when the first size relationship is used to indicate that the similarity is equal to the first preset threshold, determine a second size relationship between the first time difference and the second preset threshold, and a third size relationship between the first working time and the second working time, wherein the second working time is the working time of the first wireless access point before determining that the target device is disconnected from the first wireless access point;

[0040] It should be noted that the second preset threshold is determined by: determining multiple historical restart durations of the first wireless access point when executing a restart event, wherein the restart duration is used to indicate the duration from shutdown to restart of the first wireless access point; determining an average value of the multiple historical restart durations, and determining the second preset threshold based on the average value.

[0041] That is to say, the second preset threshold is the preset restart duration, and the preset restart duration is determined according to the average value of multiple historical restart durations when the wireless access point executes a restart event, thereby achieving the technical effect of accurately determining the preset restart duration.

[0042] It should be noted that a first time difference between a moment when a target device establishes a connection with the second wireless access point and a moment when the target device disconnects from the first wireless access point and a second preset threshold value are determined, thereby determining whether a duration for establishing a connection between the target device and the second wireless access point exceeds a preset restart duration; and a third size relationship between a first working time of the second wireless access point and a second working time of the first wireless access point is determined, thereby determining whether a rolling back of the working time of the second access point occurs.

[0043] Step 3: When the second size relationship indicates that the first time difference is less than or equal to the second preset threshold, and the third size relationship indicates that the second working duration is less than the first working duration, determine that the reason for the disconnection between the target device and the first wireless access point is that the first wireless access point is restarted.

[0044] It is understandable that when the duration of establishing the connection between the target device and the second wireless access point does not exceed the preset restart duration and the working duration of the second access point is rolled back, it is determined that the first wireless access point has executed a restart event.

[0045] In an exemplary embodiment, after determining a first size relationship between the similarity and a first preset threshold, the following steps need to be performed: when the first size relationship indicates that the similarity is less than the first preset threshold, determining that the reason for the disconnection between the target device and the first wireless access point is that the first wireless access point is powered off.

[0046] That is, when the second wireless access point and the first wireless access point are not the same wireless access point, it is directly determined that the first wireless access point is powered off.

[0047] In an exemplary embodiment, the above step S202 can be implemented by the following steps:

[0048] Step 1: Obtain a wireless access point list, and determine whether there is a second wireless access point in the wireless access point list with the same name as the first wireless access point;

[0049] Step 2: when the second wireless access point does not exist in the wireless access point list, determine a second time difference between the first time and the disconnection time, wherein the first time is used to indicate the time when it is determined that the second wireless access point does not exist in the wireless access point list;

[0050] Step 3: When the second time difference is greater than a second preset threshold, determining that the reason for the disconnection between the target device and the first wireless access point is that the first wireless access point is powered off;

[0051] It is understandable that, when the preset restart time has expired and the first wireless access point has not been connected, it is determined that the first wireless access point is powered off.

[0052] Step 4: When the second time difference is less than or equal to the second preset threshold, send an access request to a second wireless access point having the same name as the first wireless access point.

[0053] It is understandable that, when the preset restart time has not expired and the first wireless access point has not been connected, an attempt is made to send an access request to a second wireless access point having the same name as the first wireless access point to determine whether the connected second wireless access point is the first wireless access point.

[0054] In an exemplary embodiment, after sending an access request to a second wireless access point having the same name as the first wireless access point, if the second wireless access point does not respond to the access request, a third time difference between a second time and the disconnection time is determined, wherein the second time is used to indicate the time when it is determined that the second wireless access point does not respond to the access request; and if the third time difference is greater than a second preset threshold, it is determined that the reason for the disconnection between the target device and the first wireless access point is that the first wireless access point is powered off.

[0055] It is understandable that, when the preset restart time has expired and the second wireless access point with the same name as the first wireless access point has not been connected, it is determined that the first wireless access point is powered off.

[0056] In an exemplary embodiment, after determining to receive the frame data sent by the second wireless access point, the method further includes: parsing the frame data to determine a first physical address of the second wireless access point according to a first field in the frame data, and determining a first operating duration of the second wireless access point according to a second field in the frame data.

[0057] It should be noted that the frame data sent by the second wireless access point includes: a first field and a second field, wherein the first field is used to indicate the first physical address of the second wireless access point, and the second field is used to indicate the first working duration of the second wireless access point.

[0058] To better understand the process of the method for determining the above disconnection cause, the implementation method flow of determining the above disconnection cause is described below in combination with an optional embodiment, but is not intended to limit the technical solution of the embodiment of the present application.

[0059] The embodiment of the present invention records the timestamp data in the Beacon frame sent by the router through the WIFI module of the target device, and detects whether the router has been restarted through a software algorithm. The overall architecture diagram is as follows: Figure 3 As shown:

[0060] The router sends an 802.11Beacon frame to the cloud platform / mobile phone's WIFI module, and the WIFI module sends the result of whether the router has been restarted to the cloud platform / mobile phone through a TCP connection.

[0061] In this embodiment, a method for determining the disconnection cause is provided. Figure 4 is a schematic diagram of a method for determining a disconnection cause according to an embodiment of the present application, such as Figure 4 As shown, the specific steps are as follows:

[0062] Step S401: successfully connect to router A;

[0063] Step S402: Setting a router restart detection time threshold T;

[0064] For example, in the embodiment of the present invention, T is set to 150 seconds, because the time from automatic restart or power-off startup to normal operation of most wireless access points (AP, ie, routers) does not exceed 150 seconds.

[0065] Step S403: Record the BSSID of router A = BSA (equivalent to the second working time in the above embodiment);

[0066] It should be noted that the BSSID represents the MAC address of the wireless access point, and is the unique physical identifier of the wireless access point.

[0067] Step S404: receiving the Beacon frame sent by router A;

[0068] Step S405: Parse the Beacon frame to determine the Beacon timestamp (BeaconTimestamp) TS1, and record the timestamp TS1 of router A (equivalent to the second working duration in the above embodiment);

[0069] It should be noted that BeaconTimestamp will start to accumulate from 0 when the AP is powered on or restarted.

[0070] Step S406: Determine whether to disconnect from router A. If disconnected, execute step S407; otherwise, execute steps S404-S406;

[0071] Step S407: Record the time T1 of disconnection from router A;

[0072] Step S408: Determine whether a router B with the same name as router A is scanned, and if a router B with the same name as router A is scanned, execute step S409, otherwise, always try to connect to router B with the same name as router A;

[0073] Step S409: record Flag=1;

[0074] Step S410: Determine whether the connection to router B is successful. If the connection to router B is successful, execute steps S411-S417; otherwise, execute steps S418-S419;

[0075] Step S411: record the BSSID of router B = BSB;

[0076] Step S412: receiving the Beacon frame sent by router B, parsing the Beacon frame to determine the Beacon timestamp (BeaconTimestamp) TS2, and recording the timestamp TS2 of router B (equivalent to the first working duration in the above embodiment);

[0077] Step S413: record time as T2;

[0078] Step S414: Determine whether BSA is equal to BSB. If BSA is equal to BSB, execute steps S415 to S416; otherwise, execute step S417;

[0079] Step S415: Determine whether TS2 is less than TS1, and whether T2-T1 is less than T;

[0080] Step S416: When TS2 is less than TS1 and T2-T1 is less than T, it is determined that router A has been restarted;

[0081] Step S417: Determine that router A is powered off;

[0082] Step S418: Determine whether the current time - T1 is greater than T. If it is determined that the current time - T1 is greater than T, execute step S419; otherwise, execute step S408;

[0083] Step S419: Determine whether router A has a power outage.

[0084] In an embodiment of the present invention, when it is determined that a target device is disconnected from a first wireless access point, an access request is sent to a second wireless access point having the same name as the first wireless access point; when the second wireless access point responds to the access request so that the second wireless access point establishes a connection with the target device, frame data sent by the second wireless access point is received, wherein the frame data includes: a first physical address of the second wireless access point and a first working time of the second wireless access point; similarity between the first physical address and the second physical address of the first wireless access point is determined, and similarity between the connection time and the disconnection time is determined. a time difference; determining the disconnection reason between the target device and the first wireless access point according to the similarity, the first time difference and the first working time, which solves the problem that the disconnection reason between the WIFI device and the router can only be determined through user participation in the related art. The embodiment of the present invention determines the disconnection reason between the target device and the wireless access point through the similarity between the first physical address of the second wireless access point and the second physical address of the first wireless access point, and determines the first time difference between the connection time and the disconnection time, and the working time of the second wireless access point. No human participation is required, and the disconnection reason between the target device and the wireless access point can be automatically and accurately determined.

[0085] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods of each embodiment of the present application.
