Detailed Description
At present, the device identity information (or device ID) of the terminal of the internet of things may be generated and distributed uniformly by the network platform, and needs to be generated and distributed uniformly on the network platform side, and burned to corresponding hardware in the production line operation. However, when the hardware is applied to different terminals (for example, a smart speaker, a dragonfly face brushing machine, etc.), the customer requirements may not be met, and the production line production may be affected or adjusted. In addition, some service platforms of the internet of things can acquire hardware information of terminals of the internet of things and generate equipment IDs according to the hardware information. However, this results in a device ID that is closely related to the platform service and cannot pre-bind the service prior to initialization; moreover, the communication frequency is more in the initialization process, and longer time is needed; in addition, the device ID is related to the hardware information, so that the dependency of the service ID may be changed after the hardware part information is changed.
Therefore, in the development process of the internet of things system, the device ID is generally generated by collecting the device and item attributes. In order to meet the requirements of uniform format and non-repetition, generation points and distribution points of the modes are all dependent on a network platform, certain requirements are provided for the network platform, meanwhile, a set of management system is needed in identity distribution, burning operation is also needed in the production process, and the defects of non-universality of service, high production and maintenance cost and the like are caused.
In order to make the objects, technical solutions and advantages of the present disclosure more clear, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by one of ordinary skill in the art from the embodiments given herein without making any creative effort, shall fall within the scope of the implementation of the present specification.
As used herein, the term "include" and its variants mean open-ended terms in the sense of "including, but not limited to. The term "based on" means "based at least in part on". The terms "one embodiment" and "an embodiment" mean "at least one embodiment". The term "another embodiment" means "at least one other embodiment". The terms "first," "second," and the like may refer to different or the same object. Other definitions, whether explicit or implicit, may be included below. The definition of a term is consistent throughout the specification unless the context clearly dictates otherwise.
Fig. 1 is a flowchart illustrating an example of an internet-of-things device identity information generation method performed by an internet-of-things terminal according to an embodiment of the present disclosure.
The location information (or the original information) may be obtained by collecting positioning manners such as a satellite positioning system (beidou, GPS, G L ONASS, GA L I L EO, etc.), a carrier base station system, WIFI environment information, bluetooth environment information, other wireless communication location information, and IP information, for example.
In step 120, initial device identity information of the terminal of the internet of things is determined based on the acquired location information of the terminal of the internet of things. Here, the initial device identity information may be determined according to a conversion rule between the location information and the initial device identity information preset at the terminal.
In step 130, the terminal hardware identification information and the initial device identity information of the internet of things terminal are sent to the internet of things server. Here, the service end of the internet of things may determine whether the pre-stored device identity information set includes device identity information that is the same as the initial device identity information, where the device identity information set includes a plurality of pieces of terminal hardware identification information and corresponding device identity information. It should be noted that the terminal hardware identification information may be hardware component information of the terminal, and may also be other serial numbers or IDs that are burned into the hardware in the production process and can play a role in identifying the terminal hardware, such as an IMEI, an SN, a BT MAC address, a WIFI MAC address, and the like.
In some examples of the embodiments of the present specification, the service end of the internet of things may need to collect device identity information corresponding to each terminal of the internet of things (for example, collect one or more pieces of hardware information of the terminal), so as to create a device identity information set, and further provide corresponding services for each terminal of the internet of things. In some small probability events, there may be duplication between multiple (e.g., two or more) pieces of device identity information determined based on location information, such as multiple internet of things terminals having the same location information, without meeting the criteria or requirements for generating device IDs. Through the step 130, the internet of things terminal can interact and confirm with the internet of things server side, and the situation of repeated equipment IDs can be avoided.
In step 140, a feedback message about the same device identity information is received from the internet of things server, and the device identity information of the internet of things terminal is determined based on the feedback message and the initial device identity information.
In one example of the embodiments of the present specification, when the feedback message includes denial information for the same device identity information, the initial device identity information may be determined as the device identity information of the terminal of the internet of things based on the denial information. In addition, when the feedback message includes the confirmation information for the same device identity information, it may be rejected to generate the device identity information for the terminal or adjust a device ID generation manner for the terminal, which will be described in more detail below.
In the embodiment of the description, the device ID is mainly generated by the terminal of the internet of things, and the generation work of the device ID does not need to be completely handed over to the service platform, so that the universality of the device ID among a plurality of service platforms can be realized, and the degree of freedom is higher. In addition, equipment burning aiming at the equipment ID is not needed through a production line, and the production and maintenance cost of the equipment ID can be reduced. In addition, the geographic position information generation has natural exclusivity, the equipment identity determined based on the position information is not easy to repeat, the uniqueness of the generated equipment ID can be effectively guaranteed through the interaction process of the feedback information with the server, and the generation standard and the requirement of the equipment ID can be met.
In some embodiments of step 120, the terminal of the internet of things may calculate the location information according to a preset algorithm (e.g., a hash algorithm) to determine the initial device identity information. Further, in order to ensure that the determined initial device identity information has higher identification degree and uniqueness, more factors can be considered in the calculation conversion process between the position and the initial device ID. In some examples of the embodiments of the present specification, a signal strength corresponding to the location information may also be determined, and the location information and the signal strength are calculated according to a set algorithm to determine the initial device identity information. Therefore, even if the equipment at the adjacent positions is used, the collected geographic information, the collected signal strength and the like are different, and the difference can be realized on the identity information of the initial equipment aiming at different terminals of the Internet of things.
In some examples of embodiments of the present specification, the internet of things terminal can be generic across a plurality of different platforms. Specifically, there may be a service configuration in the internet of things terminal, where the service configuration includes internet of things service terminals of a plurality of internet of things service platforms associated with the internet of things terminal, for example, the internet of things service terminals of the plurality of internet of things service platforms that can provide services for the internet of things terminal. Furthermore, the internet of things terminal can send the initial equipment identity information to a plurality of associated internet of things servers according to preset service configuration. Therefore, the device ID can be commonly used on a plurality of service platforms of the Internet of things through the service configuration performed in advance aiming at the terminal.
It should be understood that the service provided by the service end of the internet of things should be adapted to the capability range of the device itself of the terminal of the internet of things, for example, if the device itself of the terminal of the internet of things does not have video capability, the service end of the internet of things corresponding to the video service does not exist in the corresponding service configuration. In addition, the initial equipment identity information can be sent to a plurality of associated internet of things servers according to the capability range of the equipment.
Fig. 2 is a flowchart illustrating an example of determining device identity information of an internet of things terminal performed by the internet of things terminal according to an embodiment of the present specification.
As shown in fig. 2, in step 210, whether the negative acknowledgement information or the difference code is included in the parsing feedback message.
If the feedback message includes negative acknowledgement information for the same device identity information, it jumps to step 221. If the feedback message includes a distinguishing code for distinguishing different terminal hardware identification information corresponding to the same device identification information, it jumps to step 223.
It should be noted that the distinguishing code may be information for distinguishing the terminal hardware identification information of the same device identity information, and may have various forms, for example, numbers may be used to distinguish different terminal hardware identification information.
In step 221, the initial device identity information is determined as the device identity information of the terminal of the internet of things based on the denial information.
In step 223, the device identity information of the terminal of the internet of things is determined based on the distinguishing code and the initial device identity information. Illustratively, the distinguishing code and the initial equipment identity information can be used as the equipment identity information of the terminal of the internet of things, and correspondingly, the server can also use the distinguishing code and the initial equipment identity information as the equipment identity information of the terminal of the internet of things. Alternatively, the terminal and the server of the internet of things can calculate or convert the distinguishing code and the initial equipment identity information based on an agreed rule, so as to obtain the equipment identity information of the terminal of the internet of things.
In the embodiment of the present specification, the internet of things terminals having the same device identity information (or initial device identity information) are distinguished by the distinguishing code configured by the server, so that the uniqueness of the generated terminal identifier of the internet of things can be ensured.
Fig. 3 is a flowchart illustrating an example of an internet of things device identity information generation method performed by an internet of things terminal according to an embodiment of the present specification.
In step 310, location information of the terminal of the internet of things is acquired.
In step 320, initial device identity information of the terminal of the internet of things is determined based on the acquired location information of the terminal of the internet of things.
In step 330, the terminal hardware identification information and the initial device identity information of the internet of things terminal are sent to the internet of things server.
In step 340, a feedback message about the same device identity information is received from the internet of things server, and the device identity information of the internet of things terminal is determined based on the feedback message and the initial device identity information.
Regarding the operations of steps 310 to 340, reference may be made to the description above with reference to steps 110 to 140 in FIG. 1.
In step 350, whether the working mode of the internet of things terminal is in a test mode or a traceless use mode is detected. Here, the terminal of the internet of things may have a plurality of operation modes (e.g., a test mode traceless use mode, a general operation mode, etc.).
If the result of the detection in step 350 indicates that the operation mode is in the test mode or the traceless use mode, it jumps to step 361. If the detection result in step 350 indicates that the operation mode is not in the test mode or the traceless use mode, it jumps to step 363.
In step 361, the determined device identity information of the terminal of the internet of things is removed. Here, it is allowed to detect the reliability of the device ID generation function of the internet of things terminal in the test mode without affecting the normal device ID generation operation of the internet of things terminal at a later stage. In addition, in a traceless use mode, the terminal of the internet of things can realize the terminal use process which is difficult to track and has a high safety factor by replacing the equipment ID.
Correspondingly, the device ID for the terminal of the internet of things in the service end of the internet of things also needs to be modified. In an example of the embodiment of the present specification, the terminal of the internet of things may send a clearing notification to the service end of the internet of things, so that the service end of the internet of things clears the terminal device identification information and the device ID corresponding to the terminal. In another example of the embodiment of the present specification, the service end of the internet of things does not need to receive the clear notification, and may perform an update operation by using a new device ID when subsequently receiving the new device ID for the terminal device identification information.
In step 363, the generation operation of the internet of things device identity information is ended.
In some application scenarios, the terminal of the internet of things may change positions during the use process. For such a situation, in an example of the embodiment of the present specification, the terminal of the internet of things completes the device ID process for the terminal of the internet of things in the first configuration process of normal start, and does not change the device ID when a location change occurs subsequently.
Fig. 4 is a flowchart illustrating an example of determining initial device identity information by an internet of things terminal according to an embodiment of the present disclosure.
In step 410, whether the device identity information exists in the terminal of the internet of things is detected.
If the detection result in step 410 indicates that no device identity information exists, it jumps to step 421. If the result of the detection in step 410 indicates the presence of the device identity information, it jumps to step 423.
In step 421, determining initial device identity information of the terminal of the internet of things based on the obtained location information of the terminal of the internet of things is triggered.
In step 423, the operation ends.
In an embodiment of the present description, the terminal of the internet of things may autonomously detect the presence of the identity information of the device, and trigger generation of the device ID only when the identity information does not exist, for example, the device ID is generated only in a first configuration process of normal start of the terminal of the internet of things, and is not updated along with a subsequent change in the location of the terminal of the internet of things.
In another example of the embodiments of the present specification, when the location of the terminal of the internet of things is changed, the device ID of the terminal of the internet of things is changed accordingly.
Specifically, the position information of the terminal of the internet of things is obtained again. Here, the location information reacquisition operation may be triggered by a power-on operation or a manual control operation of the terminal of the internet of things. In addition, the position information of the terminal of the internet of things can be acquired periodically.
And then, when the position information is found to be changed, updating the equipment identity information of the terminal of the Internet of things based on the acquired position information. Specifically, the device identity information may be generated based on the newly acquired location information, and the original device identity information of the terminal of the internet of things may be updated. Correspondingly, the equipment identity information of the terminal of the internet of things in the service end of the internet of things can be correspondingly updated.
Further, the terminal of the internet of things may be served by a plurality of internet of things servers at the same time, and in order to ensure the renewal of the service after the device ID changes, the terminal of the internet of things may receive the authorization token distributed by each internet of things server when the device ID is generated, and ensure the renewal of the service through the authorization token.
In this embodiment of the present description, when the location of the terminal in the internet of things changes, the terminal in the internet of things may update the device identity information of the terminal in the internet of things based on the obtained location information, and the device ID is not bound to the device hardware and has strong flexibility.
Fig. 5 is a flowchart illustrating an example of an internet of things device identity information generation method performed by an internet of things server according to an embodiment of the present specification.
In step 510, terminal hardware identification information and initial device identity information are received and stored from the internet of things terminal. Here, the initial device identity information is determined by the terminal of the internet of things according to the location information, and further details may refer to details described in other relevant parts above, which are not described herein again.
In step 520, it is determined whether the pre-stored set of device identity information has the same device identity information as the initial device identity information. Here, the device identity information set includes a plurality of terminal hardware identification information and corresponding device identity information.
In step 530, a feedback message is generated according to the judgment result, and the feedback message is sent to the terminal of the internet of things.
In step 540, the device identity information of the terminal of the internet of things is determined based on the feedback message and the initial device identity information.
In the embodiment of the present specification, an initial device ID is determined based on the terminal of the internet of things, and whether there is repeated device identity information is verified by the server based on the device identity information set, so that the uniqueness of the device ID of each terminal of the internet of things can be ensured.
Fig. 6 is a flowchart illustrating an example of determining device identity information of an internet of things terminal performed by an internet of things server according to an embodiment of the present specification.
As shown in fig. 6, in step 610, it is determined whether the same device identity information as the initial device identity information exists in the device identity information set.
If the determination result in step 610 indicates that the device identity information set does not have the same device identity information as the initial device identity information, step 621 is skipped. If the determination result in step 610 indicates that the device identity information set contains the same device identity information as the initial device identity information, the process jumps to step 623.
In step 621, a feedback message is generated according to the denial information for the same device identity information.
Then, in step 631, a feedback message is sent to the terminal of the internet of things.
Next, in step 641, based on the denial information, the initial device identity information is determined as the device identity information of the terminal of the internet of things.
In addition, in step 623, corresponding distinguishing codes are configured for each piece of terminal hardware identification information corresponding to the same equipment identity information and initial equipment identity information, respectively.
Next, in step 633, a feedback message is generated based on the discrimination code.
Next, in step 643, a feedback message is sent to the terminal of the internet of things.
Next, in step 650, the device identity information of the terminal of the internet of things is determined according to the initial device identity information and the distinguishing code.
In the embodiment of the description, when the same device identity information is caused by the overlapping of the position information and other factors, the final device identity information can be generated by the distinguishing codes for distinguishing different internet of things terminals, so that the uniqueness of the device ID is guaranteed.
It should be noted that, in some examples of the embodiments of the present specification, the terminal of the internet of things can be used in common among a plurality of different platforms, or the terminal of the internet of things can be served by a plurality of service terminals of the internet of things, and at this time, the same device identity information problem may be caused by factors such as overlapping of location information. In some examples of the embodiments of the present description, each internet of things server may configure different difference codes for the internet of things terminal based on a difference code generation mechanism thereof, so that the internet of things terminal may communicate with the corresponding internet of things server by using the corresponding difference codes.
In some application scenarios, the device ID of the terminal of the internet of things is updated along with the change of the location, and in order to ensure the continuity of the service, the authorization token may be sent to the corresponding terminal of the internet of things when the device ID is generated by the service end of the internet of things. Therefore, even if the device ID of the terminal of the Internet of things changes, the existence of the service can be guaranteed based on the authorization token.
Fig. 7 is a signal interaction diagram illustrating an example of an internet of things device identity information generation method according to an embodiment of the present specification.
As shown in fig. 7, in step 701, the internet of things terminal 710 acquires location information.
In step 703, the internet of things terminal 710 determines initial device identity information of the internet of things terminal based on the obtained location information of the internet of things terminal. Here, the device ID is generated with the position information as an input, and the algorithm setting is flexible and may not be limited. But to avoid duplication it may be recommended to do a hash operation on the location information.
In some embodiments, the internet of things terminal 710 may further detect whether the device ID already exists locally, and trigger a subsequent device ID generation operation only when the device ID does not exist locally at the terminal.
In step 705, the internet of things terminal 710 sends the terminal hardware identification information and the original device source information to the internet of things server 720.
In step 707, the service end 720 of the internet of things determines whether there is the same device identity information as the initial device identity information in the set of pre-stored device identity information. Illustratively, if the server finds that there are terminal devices with the same device ID but different hardware information according to the record, a corresponding distinguishing code (or repetition number) may be given for each hardware information, thereby feeding back the repetition number according to the hardware information.
In step 709, the internet of things server 720 generates a feedback message according to the judgment result. In some examples, the feedback message may include the result of the terminal's registration with the platform and a corresponding difference code.
In step 711, the internet of things server 720 sends a feedback message to the internet of things terminal 710.
In step 715, the internet of things terminal 710 determines a device ID according to the feedback message and the initial device identity information. And
in step 717, the service end 720 of the internet of things determines the device ID according to the feedback message and the initial device identity information.
In some examples of embodiments of the present specification, the initial device identity information and the distinguishing code may be taken together as a device ID.
In step 719, the internet of things terminal 710 detects whether the operating mode is in the test mode or the traceless use mode. Here, when it is detected that the operation mode is in the test mode or the traceless use mode, it jumps to step 721.
In step 721, the terminal 710 of the internet of things clears the determined device identity information of the terminal of the internet of things.
In step 723, the internet of things terminal 710 sends a device ID clear notification to the internet of things server 720.
In step 725, the internet of things server 720 clears the terminal hardware identification information and the corresponding device ID corresponding to the internet of things terminal 710. Therefore, the terminal of the Internet of things supports the test behavior in the test mode, so that the test mode does not influence the normal equipment ID generation.
In the embodiment of the specification, the device ID is mainly determined according to the terminal of the internet of things, and compared with a generation scheme of a pure server, special information is not required to be burnt, a production flow of a production line is not required to be changed, and the device ID is irrelevant to the service attribute. In addition, the local generation algorithm of the device ID can avoid repetition with great probability, so that little information or even no information can be acquired by acquiring the hardware information. Meanwhile, the equipment ID is irrelevant to the service, and the equipment ID can be registered without the platform association service. In addition, since the data communication process between the terminal and the server is simple (for example, only one time of uplink and downlink of data is needed), the registration process is simple and fast.
It should be understood that, in the embodiment of the present specification, the deduplication process for the hardware information is only used with a low probability, and therefore, the situation caused by the location of the terminal device being unchanged and the hardware being changed is negligible.
