[0046] Embodiment 1

[0047] As shown in Figure 1 , a network signaling flow sampling method, the method comprising the following steps:

[0048] by signaling interaction with the accessed terminal;

[0049] In the embodiment, the network access point AP performs signaling interaction with the accessed terminal, and the signaling interaction includes connection establishment, response mode negotiation, roaming control, state query, disconnection and the like.

[0050] Detecting terminal information according to the association frame of the terminal;

[0051] In the signaling interaction process between the terminal and the network access point AP, the network access point receives the association frame sent by the terminal, and detects terminal information according to the association frame of the terminal, including determining the manufacturer and model of the terminal according to the vendor specific field content and MAC address in the association frame of the terminal.

[0052] Obtaining a management frame of a wireless local area network, and identifying a signaling flow according to a preset signaling flow template;

[0053] In the embodiment, in the signaling interaction process between the terminal and the network access point AP, the signaling is generally transmitted in the form of a management frame, and therefore, the signaling flow corresponding to the signaling can be identified according to the type, sequence, time interval and other information of the management frame and the preset signaling flow template.

[0054] Storing the identified signaling flow and terminal information in the local terminal;

[0055] The embodiment associates the obtained signaling flow and terminal information, and specifically, a one-to-one mapping relationship can be established, the signaling flow corresponding to the terminal information can be queried according to the terminal information, and the terminal information corresponding to the signaling flow can be queried according to the signaling flow, so that the signaling flow of the target terminal can be quickly found, and the problems of interworking and compatibility can be conveniently solved.

[0056] When the trigger condition of data transmission is met, the signaling flow is transmitted to the server after encryption, so that the server updates the flow library according to the received signaling flow and terminal information, and identifies the state of the signaling flow, and the terminal information is queried according to the terminal information.

[0057] The embodiment transmits the signaling flow to the server after encryption, and in the transmission process, the AES encryption algorithm and the MD5 message digest algorithm are used for transmission. Specifically, the network access point AP uses the AES encryption algorithm to encrypt the signaling flow in units of signaling flow, and transmits the encrypted signaling flow and the terminal information corresponding to the signaling flow to the server. The server decrypts the received encrypted data by using the AES encryption algorithm, and obtains the corresponding signaling flow and terminal information. In order to further ensure the consistency of the transmitted data, the MD5 message digest algorithm is also used to ensure the consistency of the received file and the transmitted file, and prevent the file from being tampered in the transmission process.

[0058] The server includes an entity server and a cloud service.

[0059] In one specific embodiment, the preset signaling flow template includes an authentication association flow template, a block response request response flow template, a roaming flow template, and a disconnection flow template.

[0060] According to the authentication association flow template, the authentication association flow can be identified; according to the block response request response flow template, the block response request response flow can be identified; according to the roaming flow template, the roaming flow can be identified; and according to the disconnection flow template, the disconnection flow can be identified.

[0061] In one specific embodiment, the trigger condition of the data transmission includes: when the local storage space occupancy rate exceeds a preset value, and the server data collection function is idle, the trigger condition of the data transmission is met, and the data transmission function is started.

[0062] In this embodiment, the preset value is set to 50%, or 60%, or 70%, which is set according to actual use. When the local storage space occupancy rate reaches the preset value, the data stored in the local storage space is transmitted to the server, which is beneficial to reduce the amount of data storage and improve the utilization rate of the local storage space.

[0063] Further, the flow library is updated according to the received signaling flow and terminal information, including:

[0064] According to the received signaling flow and terminal information, the signaling flow in the flow library is compared. If the same signaling flow already exists, the received signaling flow is discarded. If no same signaling flow is found, the received signaling flow and terminal information are saved to the flow library, thereby updating the flow library.

[0065] The comparison of the received signaling flow and terminal information with the signaling flow in the flow library includes: the signaling key field in the signaling flow is matched in full content. If the same signaling flow is matched, it is considered that the two signaling flows are the same, and the received signaling flow is discarded. If the matching is not the same, it is considered that no same signaling flow is found, and the received signaling flow and terminal information are saved to the flow library, thereby updating the flow library.

[0066] In one specific embodiment, the state of the signaling flow is identified, including:

[0067] According to the key signaling result value in the signaling flow, it is determined whether the signaling flow is normally completed or abnormally terminated, and the corresponding identification is made.

[0068] In one specific embodiment, before the server updates the procedure library according to the received signaling procedure and terminal information, the method further comprises: the server classifies the received signaling procedure according to a preset sampling category, and marks an interworking processing method for each category; and then compares the signaling procedure with the signaling procedures in the procedure library, and updates the procedure library.

[0069] The embodiment identifies the signaling procedure according to the management frame and the preset signaling procedure template, and belongs to coarse classification, which only distinguishes the signaling procedures of large categories. However, the signaling procedures can still have multiple categories, and therefore the embodiment subdivides the procedures that are different from each other in one large category into different sampling categories. For example, in the authentication association procedure, the authentication association procedure can be in different manners such as open type, fast switching, SAE authentication, and the like, and the corresponding interworking processing method is marked.

[0070] In the later maintenance and debugging process, the interworking processing method corresponding to the signaling procedure of different sampling category can be quickly queried, so as to improve the work efficiency.

[0071] Embodiment 2

[0072] A network signaling procedure sampling method, as shown in Figure 2 The method comprises the following steps:

[0073] When the trigger condition of data transmission is met, the data transmitted by the network access point AP in a signaling procedure unit is received, and the data comprises terminal information and a signaling procedure; the terminal information is detected by the network access point AP according to the association frame of the acquired terminal; and the signaling procedure is obtained by the network access point AP through acquiring the management frame of the wireless local area network and identifying the preset signaling procedure template;

[0074] In the signaling interaction process between the network access point AP and the accessed terminal, the association frame sent by the terminal is received, and the terminal information is detected by the network access point according to the acquired association frame of the terminal, comprising: determining the manufacturer and model of the terminal according to the content of the vendor specific field and the MAC address in the association frame of the terminal.

[0075] In the embodiment, in the signaling interaction process between the terminal and the network access point AP, the signaling is generally transmitted in the method of management frame, and therefore the signaling procedure corresponding to the signaling can be identified according to the type, sequence, time interval and the like of the management frame and the preset signaling procedure template.

[0076] The network access point AP stores the identified signaling flow and terminal information locally; associates the obtained signaling flow with the terminal information, and specifically, a one-to-one mapping relationship can be established, the signaling flow corresponding to the terminal information can be queried according to the terminal information, or the terminal information corresponding to the signaling flow can be queried according to the signaling flow. Thus, the signaling flow of the target terminal can be quickly found, and the interworking and compatibility problems can be conveniently solved.

[0077] updating the flow library according to the received signaling flow and terminal information, and identifying the state of the signaling flow;

[0078] In response to the query instruction, the flow library is queried according to the terminal information, and the query result is fed back to the user terminal.

[0079] For example, if a report indicates that a certain brand of mobile phone has a problem when accessing the network access point AP, the BSSID of the brand and the AP is used as a query condition to list all the flow samples of the mobile phone of the brand on the AP, and then the abnormal flow is screened out.

[0080] Further, updating the flow library according to the received signaling flow and terminal information includes:

[0081] comparing the received signaling flow and terminal information with the signaling flow in the flow library, if the same signaling flow already exists, discarding the received signaling flow; if no same signaling flow is found, saving the received signaling flow and terminal information to the flow library, thereby updating the flow library.

[0082] The comparison of the received signaling flow and terminal information with the signaling flow in the flow library includes: performing full content matching on the signaling key fields in the signaling flow, if the same signaling flow is matched, it is considered that the two signaling flows are the same, and the received signaling flow is discarded; if the same signaling flow is not matched, it is considered that no same signaling flow is found, and the received signaling flow and terminal information are saved to the flow library, thereby updating the flow library.

[0083] In a specific embodiment, identifying the state of the signaling flow includes:

[0084] According to the key signaling result value in the signaling flow in a specific embodiment, before the server updates the flow library according to the received signaling flow and terminal information update flow library, the method further comprises: the server classifies the received signaling flow according to a preset sampling category, and marks the interworking processing method for each category; then compares with the signaling flow in the flow library, and updates the flow library. In this embodiment, the signaling flow is identified according to the management frame and the preset signaling flow template, and the identified signaling flow belongs to coarse classification, which only distinguishes the signaling flow of the large category. However, these signaling flows may still have multiple categories, so this embodiment subdivides the flows that are different from each other in a large category into different sampling categories, such as the authentication association flow, which can be open, fast switching, SAE authentication and other different ways, and marks the corresponding interworking processing method.

[0085] In the later maintenance debugging process, the interworking processing method corresponding to the signaling flow of different sampling categories can be quickly queried, thereby improving the work efficiency.
