In order to make the objects, technical solutions and advantages of the present application more apparent, specific embodiments of the present application will be described in detail with reference to the accompanying 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 but not all of the relevant portions of the present application are shown in the drawings. 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 operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. 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.
The first embodiment is as follows:

Generally, the traffic classification-based signal transmission mode selection device may be an internet of things system.
The following description will be made taking a traffic classification-based signal transmission mode selection apparatus as an example of a main body that performs a traffic classification-based signal transmission mode selection method. Referring to fig. 1, the method for selecting a signal transmission mode based on service classification specifically includes:
s110, the terminal of the Internet of things determines a corresponding service grade based on the service type of the current service data, and the service type is configured with the corresponding service grade in advance.
The embodiment of the application provides a signal transmission mode selection method based on service classification, which aims to set different service classes according to different service types, set different signal transmission modes according to different service classes, and adaptively transmit service data of various signal transmission requirements based on different signal transmission modes, so that the signal transmission processing efficiency can be adaptively improved while the signal transmission safety requirements are guaranteed, and the operation of an internet of things system is optimized.
Specifically, in the embodiment of the present application, corresponding service classes are configured in advance for different service types to which service data pertains. The method comprises the steps of setting a relatively low service grade for a service type with a low signal transmission safety requirement, and setting a relatively high service grade corresponding to a service type with a high signal transmission safety requirement. It will be appreciated that the requirements for signal transmission security may differ in view of the different traffic types. For the service types with relatively high service grades and relatively important service types, when the terminal of the internet of things transmits service data of corresponding service types, the signal transmission safety is required to be relatively high, and the influence of stealing, leaking and the like of the service data on the receiving processing of related services is avoided. For the service type with a relatively low service level, the service transmission can be directly performed by configuring the relatively low service level when the service data transmission is performed based on the relatively low service level, and the process of encrypting the service data is omitted, so that the transmission processing efficiency of the service data is improved, and the operation of the internet of things system is optimized.
In one embodiment, the internet of things gateway issues level configuration information to the internet of things terminal, and modifies the service level of the corresponding service type configuration based on the level configuration information. And modifying the configuration relation between the service type and the corresponding service grade by issuing grade configuration information through the gateway of the Internet of things so as to enable the transmission of service data to meet the real-time safety transmission requirement of the system. For example, when the service level of service data of a certain service type needs to be raised, the internet of things gateway reconfigures the service level of the service type through the level configuration information. And after the grade configuration information is sent to the Internet of things terminal, the Internet of things terminal reconfigures the service grade of the service type according to the grade configuration information.
S120, the Internet of things terminal selects a corresponding signal transmission mode according to the service level, adds a corresponding service level identifier to the service data, and uploads the service data to an Internet of things gateway based on the signal transmission mode; the signal transmission mode comprises a first signal transmission mode, a second signal transmission mode and a third signal transmission mode, the internet of things terminal directly transmits the service data to the internet of things gateway in the first signal transmission mode, the internet of things terminal encrypts the service data by using a preset encryption key and transmits the service data to the internet of things gateway in the second signal transmission mode, the internet of things terminal encrypts the service data by using the encryption key and preset artificial noise and transmits the service data to the internet of things gateway in the third signal transmission mode, and the artificial noise corresponds to the natural noise corresponding setting of a receiving channel of the internet of things gateway.
In order to enable the terminal of the internet of things to adaptively select a signal transmission mode for transmitting service data, in the embodiment of the application, a plurality of signal transmission modes are preset, a mapping relation is established between the signal transmission mode and each different service level, and when service data of a certain service level is transmitted, the corresponding signal transmission mode is used for transmitting the service data. Generally speaking, corresponding service levels are set according to the number of the signal transmission modes, in the embodiment of the application, three different signal transmission modes are adopted, and the safety performance of signal transmission is gradually improved according to the service levels from low to high. When the service data is transmitted, the first signal transmission mode is used for directly transmitting the service data, wherein the corresponding service type is low in service level and irrelevant. Therefore, the complex flow caused by encryption transmission of the service data can be reduced, and the efficiency of signal transmission processing is improved. For the relatively important service type, the service grade is relatively high, when the service data is transmitted, the second signal transmission mode is used for transmitting the service data, and when the service data is transmitted, the set encryption key is used for encrypting and then transmitting the encrypted service data. The encryption key is issued by the gateway of the Internet of things, and the gateway of the Internet of things reserves a corresponding decryption key when issuing the encryption key so as to facilitate subsequent data decryption. Generally speaking, the service data encryption transmission adopts an asymmetric encryption transmission mode, the internet of things terminal encrypts the service data through a public key, and the internet of things gateway decrypts the service data by using a reserved private key after receiving the service data, so as to realize the encryption transmission of the service data. By encrypting and transmitting the service data, the safety of service data transmission can be guaranteed to a certain extent, the safe operation of an Internet of things system is guaranteed, and the conditions that the service data is stolen, leaked and the like are avoided. In addition, the service data corresponding to the high security requirement has the highest service level, and when the service data is transmitted, the service data is transmitted by using the third signal transmission mode. When the service data is transmitted, not only the encryption key is needed to be used, but also the service data is coded and processed by combining with the set artificial noise. It can be understood that the artificial noise is set according to the natural noise of the service data receiving channel of the gateway of the internet of things, and the artificial noise and the natural noise can be mutually offset. Based on the principle, when the service data is transmitted, the artificial noise of the received service data corresponding to the gateway of the internet of things can be cancelled by mutual cancellation of the natural noise of the receiving channel, and for a third-party eavesdropper, the natural noise of the receiving channel is different from that of the gateway of the internet of things, and when the service data of the terminal of the internet of things is received, the original service data is difficult to restore due to the influence of the artificial noise and the natural noise of the receiving channel. Therefore, the difficulty of stealing the service data can be increased, and the safety of service data transmission is further improved.
Based on the signal transmission modes preset for the three corresponding service levels, when service data transmission is performed, one signal transmission mode is selected from the three signal transmission modes according to the service level determined in the step S110 to perform service data transmission. And when transmitting the service data, further adding a service level identifier in the service data, so that the gateway of the internet of things determines the service level of the service data according to the service level identifier, and determines a signal transmission mode of the gateway of the internet of things to receive and process the service data.
In one embodiment, the internet of things gateway sends the new encryption key to the internet of things terminal every other preset security management period, and updates the encryption key. The internet of things gateway periodically updates a session key corresponding to the internet of things terminal service data every other security management period, wherein the session key comprises an encryption key and a decryption key, the encryption key is sent to the internet of things terminal for replacing and updating the encryption key, and the decryption key is reserved for subsequent service data decryption. By periodically updating the encryption key, the difficulty of cracking and stealing the service data can be increased, and the safety of service data transmission is improved.
In one embodiment, the internet of things gateway periodically detects the natural noise of a receiving channel, and updates the artificial noise preset by the internet of things terminal based on the natural noise. It can be understood that, under the influence of various factors of the communication network, the natural noise of the gateway receiving channel of the internet of things also changes in real time, so that the embodiment of the application periodically detects the natural noise and adaptively modifies the artificial noise according to the detection result of the natural noise to ensure that the artificial noise and the natural noise are approximately completely offset, and the integrity and the safety of service data transmission are ensured.
In one embodiment, the internet of things gateway sends gateway change information to the internet of things terminal, and indicates the internet of things terminal to use a standby gateway as a receiving end of the service data, where the gateway change information includes IP address information of the standby gateway, natural noise information of a receiving channel, and the corresponding encryption key. Under the conditions of abnormal operation, equipment upgrading and the like of the Internet of things gateway, the standby gateway needs to be replaced to receive the service data sent by the Internet of things terminal so as to ensure normal processing of the service data and enable the Internet of things system to be normally carried out. Based on this, when the thing networking gateway is changed, through issuing gateway change information to thing networking terminal. And the terminal of the Internet of things responds to the gateway change information, and transmits the service data to the standby gateway according to the IP address information of the standby gateway, the natural noise information of the receiving channel and the corresponding encryption key contained in the gateway change information, so that the normal transmission processing of the service data is ensured. It can be understood that the encryption key and the artificial noise used in the second signal transmission mode and the third signal transmission mode can be determined according to the natural noise information of the standby gateway receiving channel and the corresponding encryption key, and further, the service data is transmitted based on the IP address information of the standby gateway.
S130, the gateway of the Internet of things receives the service data, analyzes the service data to obtain the service level identification, determines the signal transmission mode corresponding to the service data based on the service level identification, directly processes the service data if the signal transmission mode is the first signal transmission mode, and decrypts and processes the service data by using a preset decryption key if the signal transmission mode is the second signal transmission mode or the third signal transmission mode.
Correspondingly, referring to fig. 2, when receiving the service data, the gateway of the internet of things may receive and process the service data by using different processing modes according to different signal transmission modes of the current service data. The method comprises the steps of analyzing a service level identifier of service data, inquiring mapping relation information of a service level and a corresponding signal transmission mode, wherein the mapping relation information is constructed in advance based on the service level identifier, and determining the signal transmission mode corresponding to the service data based on the mapping relation information. After the signal transmission mode is determined, the processing of the traffic data according to the signal transmission mode can be adaptively performed. If the service data is transmitted in the first signal transmission mode, the service data is directly decrypted. If the second signal transmission mode and the third signal transmission mode are adopted, the reserved decryption key is needed to be used for decrypting the service data. It can be understood that, compared with the second signal transmission mode, the third signal transmission mode can further ensure the transmission security of the service data and simultaneously offset the natural noise of the receiving channel through the artificial noise by adding the artificial noise, so that the transmission quality of the service data is better and the signal transmission performance is further optimized. And the service data processing mode is the same corresponding to one end of the gateway of the Internet of things. The internet of things terminal needs to add a process of processing service data by artificial noise coding, so that the second signal transmission mode or the third signal transmission mode is adaptively selected to transmit the service data of the corresponding service level in consideration of the requirements of service data processing efficiency and transmission safety.
In one embodiment, the internet of things gateway modifies the mapping relationship information according to a real-time signal transmission requirement, and updates the mapping relationship information to the internet of things terminal. It can be understood that, according to the real-time transmission requirements of service data of different service levels, when the signal transmission mode needs to be changed corresponding to the service level, the corresponding mapping relationship information is changed, and the mapping relationship information is updated to the terminal of the internet of things to realize the signal transmission change corresponding to the service level, so as to ensure that the service data transmission corresponding to the service level meets the safety transmission requirement in real time.
In the above, the corresponding service class is determined based on the service type of the current service data through the terminal of the internet of things, and the corresponding service class is preconfigured in the service type. And the terminal of the Internet of things selects a corresponding signal transmission mode according to the service level, adds a corresponding service level identifier to the service data, and uploads the service data to the gateway of the Internet of things based on the signal transmission mode. The signal transmission mode comprises a first signal transmission mode, a second signal transmission mode and a third signal transmission mode, under the first signal transmission mode, the internet of things terminal directly transmits service data to the internet of things gateway, under the second signal transmission mode, the internet of things terminal encrypts the service data by using a preset encryption key and transmits the service data to the internet of things gateway, under the third signal transmission mode, the internet of things terminal encrypts the service data by using the encryption key and preset artificial noise and transmits the service data to the internet of things gateway, and the artificial noise corresponds to the natural noise of a receiving channel of the internet of things gateway and is set. The method comprises the steps that the gateway of the Internet of things receives service data, analyzes the service data to obtain a service level identification, determines a signal transmission mode corresponding to the service data based on the service level identification, directly processes the service data if the signal transmission mode is the first signal transmission mode, and decrypts the service data and processes the service data by using a preset decryption key if the signal transmission mode is the second signal transmission mode or the third signal transmission mode. By adopting the technical means, the signal transmission mode can be adaptively selected, the safety requirement of signal transmission is guaranteed, and the signal transmission processing efficiency is adaptively improved.
