[0023] Next, the embodiments of the present application are described in detail.

[0024] The present application embodiment provides a message processing method, which is applied to a wireless access device, such as Figure 1 As shown, the method may include the following steps:

[0025] S11. When receiving a management message sent by a first wireless terminal for the first time, if the management message carries a designated field, judging whether the first wireless terminal is a trusted terminal according to the encryption information in the designated field; if the judgment result is no, executing step S12; if the judgment result is yes, executing step S13;

[0026] In this step, the designated field may be a newly added element identifier (Element ID) field, for example, field 221, etc. The designated field may include the manufacturer identifier of the manufacturer to which the first wireless terminal belongs, the message priority trusted by the first wireless terminal (for example, 802.11e priority, Differentiated Services Code Point (DSCP) priority, etc.), encryption information, etc.

[0027] Here, the encryption information is obtained by the first wireless terminal encrypting the timestamp when sending the management message according to a preset encryption algorithm. For example, the preset encryption algorithm may be an Advanced Encryption Standard (AES) encryption algorithm.

[0028] It should be noted that when the management message does not carry the designated field, the wireless access device still processes the management message in the existing manner, and subsequently processes the data message in the existing manner when receiving the data message sent by the first wireless terminal in this situation.

[0029] S12. Process the management message according to the existing method.

[0030] It should be noted that, in this case, when the wireless access device receives the data message sent by the first wireless terminal, it also processes the data message in the existing manner.

[0031] S13: Add the first wireless terminal to a trusted terminal list corresponding to the manufacturer identifier of the manufacturer to which the first wireless terminal belongs in the locally created designated field, record the message priority trusted by the first wireless terminal in the designated field, and process the management message.

[0032] S14. When receiving a data message sent by the second wireless terminal, if the second wireless terminal is a wireless terminal in the local trusted terminal list, the data message is forwarded after priority mapping is performed according to the message priority trusted by the second wireless terminal recorded locally.

[0033] In this step, the level corresponding to the priority of the message trusted by the wireless terminal in the local trusted terminal list is higher than the level corresponding to the priority of the message trusted by the wireless terminal not in the local trusted terminal list.

[0034] It should be noted that, for the wireless access device, when receiving a data message sent by the second wireless terminal, if it is determined that the second wireless terminal is not a wireless terminal in the local trusted terminal list, the data message is still processed in the existing manner.

[0035] Specifically, in the above step S11, the wireless access device may determine whether the first wireless terminal is a trusted terminal in the following manner:

[0036] Decrypt the encrypted information according to a preset decryption algorithm corresponding to the preset encryption algorithm to obtain a timestamp;

[0037] Calculate the difference between the current timestamp and the timestamp;

[0038] If the calculated difference is not greater than the set threshold, determining that the first wireless terminal is a trusted terminal;

[0039] If the calculated difference is greater than a set threshold, it is determined that the first wireless terminal is not a trusted terminal.

[0040] It should be noted that, in the above judgment process, when the preset encryption algorithm is the AES encryption algorithm, the preset decryption algorithm is the AES decryption algorithm.

[0041] Furthermore, the threshold value may be set according to the actual network conditions of the WLAN where the wireless access device is located. For example, the threshold value may be 1 minute.

[0042] Further, in the embodiment of the present application, in order to improve the accuracy of the determination of the trusted terminal, when the wireless access device finds that the calculated difference is greater than the set threshold, it may not directly determine that the first wireless terminal is not a trusted terminal, but perform the following operations:

[0043] Notify the first wireless terminal to update the encryption information in the designated field carried in the management message;

[0044] Upon receiving the updated management message sent by the first wireless terminal, decrypting the encrypted information in the designated field in the updated management message according to a preset decryption algorithm to obtain a new timestamp, wherein the new timestamp is the timestamp when the first wireless terminal sends the updated management message;

[0045] The difference between the current timestamp and the new timestamp is calculated, and when the calculated difference is not greater than a set threshold, the first wireless terminal is determined to be a trusted terminal, and when the calculated difference is greater than the set threshold, the first wireless terminal is determined to be an untrusted terminal.

[0046] In this operation process, when the wireless access device notifies the first wireless terminal to update the encrypted information in the specified field carried in the management message, it can send a notification message carrying the specified field to the first wireless terminal. The encrypted information in this specified field is obtained by the wireless access device after encrypting the first specified information (for example, 0x00000000, etc.) according to a preset encryption algorithm, and is used to instruct the first wireless terminal to update the encrypted information.

[0047] Subsequently, after receiving the notification message, the first wireless terminal will decrypt the encrypted information in the designated field carried in the notification message according to a preset decryption algorithm to obtain the first designated information; thereafter, the first wireless terminal will send an updated management message to the wireless access device, and the encrypted information in the designated field carried in the updated management message is obtained by encrypting the timestamp when sending the updated management message by the first wireless terminal according to the preset encryption algorithm.

[0048] Specifically, in the above step S13, when the wireless access device processes the management message, it can process the management message in an existing manner, or it can send a corresponding response message carrying a specified field to the first wireless terminal. The encrypted information in this specified field is obtained by the wireless access device according to a preset encryption algorithm. The second specified information (for example, 0xffffffff, etc.) is encrypted, and is used to indicate that the first wireless terminal does not need to update the encryption information.

[0049] After receiving the response message, the first wireless terminal will decrypt the encrypted information in the designated field carried in the response message according to a preset decryption algorithm to obtain the second designated information; thereafter, the first wireless terminal will communicate with the wireless access device in the existing manner.

[0050] Further, in the embodiment of the present application, in order to improve network security, after the wireless access device adds the first wireless terminal to the trusted terminal list corresponding to the manufacturer identifier of the manufacturer to which the first wireless terminal belongs in the locally created designated field, it may also perform the following operations:

[0051] Start the timer;

[0052] When the timing duration of the timer reaches a preset first duration, notifying the first wireless terminal to update the encryption information in the designated field carried in the management message;

[0053] If an updated management message sent by the first wireless terminal is received before the timing duration of the timer reaches a preset second duration, re-determine whether the first wireless terminal is a trusted terminal based on the encrypted information in the designated field in the updated management message, and restart the timer when the determination result is yes, and delete the first wireless terminal from the corresponding trusted terminal list when the determination result is no, and if a management message sent by the first wireless terminal is received again after the first wireless terminal is deleted, the management message sent again by the first wireless terminal is regarded as the management message received for the first time, and the step of determining whether the first wireless terminal is a trusted terminal based on the encrypted information in the designated field is executed, wherein the preset second duration is greater than the preset first duration;

[0054] If the management message resent by the first wireless terminal has not been received when the timing duration of the timer reaches the preset second duration, the first wireless terminal will be deleted from the corresponding trusted terminal list. If a management message resent by the first wireless terminal is received after the first wireless terminal is deleted, the management message resent by the first wireless terminal will be regarded as the management message received for the first time, and the step of determining whether the first wireless terminal is a trusted terminal based on the encrypted information in the designated field will be executed.

[0055] It should be noted that in this operation process, the above-mentioned preset first duration and the preset second duration can be set according to the actual network conditions of the WLAN where the wireless access device is located. For example, the above-mentioned preset first duration can be 9 minutes, etc., and the above-mentioned preset second duration can be 10 minutes, etc. The above-mentioned preset second duration can be understood as the trust duration that the first wireless terminal is a trusted terminal.

[0056] It should be further explained that, in the above step S14, the second wireless terminal and the first wireless terminal may be the same wireless terminal, or they may be different wireless terminals.

[0057] The local trusted terminal list may include wireless terminals from only one wireless terminal manufacturer or from multiple wireless terminal manufacturers.

[0058] Once the wireless access device receives a data message sent by any wireless terminal in the local trusted terminal list, it will perform priority mapping on the data message according to the locally recorded message priority of the wireless terminal and then forward it. Since the level corresponding to the message priority trusted by the wireless terminal is higher, the corresponding data message will be forwarded by the wireless access device first, thereby improving the user experience of the user holding the wireless terminal.

[0059] It should be further explained that in the embodiments of the present application, the wireless access device can be a fat AP; it can also be a thin AP, in which case the forwarding mode of the WLAN where the wireless access device is located is a local forwarding mode; of course, it can also be an access controller (AC), in which case the forwarding mode of the WLAN where the wireless access device is located is a centralized forwarding mode.

[0060] It can be seen from the above technical solutions that in the embodiment of the present application, the wireless access device determines whether the wireless terminal is a trusted terminal based on the management message of the wireless terminal from a certain manufacturer, and when the judgment result is yes, when the data message of the wireless terminal is subsequently received, the wireless access device directly forwards the data message after priority mapping based on the message priority trusted by the terminal (the level of this message priority is higher than the level of the message priority trusted by the wireless terminal that is not a trusted terminal). In this way, the requirements of the wireless terminal of a specific manufacturer for the priority processing of data messages of certain services can be met, thereby improving the poor experience of the corresponding users.
