Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, a flowchart illustrating steps of a resource subscription method for an internet of things device according to an embodiment of the present invention is shown, and the method specifically includes the following steps:
step 101, registering Internet of things equipment.
In a specific implementation, the embodiment of the present invention may be applied to an internet of things platform, where the internet of things platform may be an independent computing device or a computing cluster, and the embodiment of the present invention is not limited thereto.
On the one hand, the internet of things equipment, such as an electric meter, a water meter, a meteorological monitor and the like, is registered in the internet of things platform, and is accessed into the internet of things platform, and the internet of things platform is communicated with the internet of things platform according to an internet of things protocol, so that the instruction of the internet of things platform is received, and corresponding processing is carried out, or subscribed equipment resources, such as user electricity consumption, user water consumption, temperature and the like, are reported to the internet of things platform.
On the other hand, the service platform is connected with the internet of things platform, and subscribes the equipment resources of the internet of things equipment according to service requirements, performs corresponding service processing, such as statistics of daily or monthly user electricity consumption to generate an electricity consumption billing list, and draws a daily or daily temperature curve change chart.
In an embodiment, as shown in fig. 2, the internet of things device 200 is configured with an internet of things communication module 211, and the internet of things communication module 211 may access a processor of the internet of things device 200 through RS485, UART (Universal Asynchronous receiver transmitter), I2C (Inter Integrated Circuit), and communicate with the processor.
Generally, the Internet of things device 200 (Internet of things communication module 211) is located in an intranet 210 of an operator, and the Internet of things platform 231 is located in a public Network 230 of the operator, so that data sent to the base station 212 by the Internet of things device 200 (Internet of things communication module 211) is subjected to Address mapping from the intranet 210 to the public Network 230 through a NAT (Network Address Translation) server 220, and then is forwarded to the Internet of things platform 231 through a UDP (User data Protocol)/IP (Internet Protocol Address), and similarly, data of the Internet of things platform 231 is subjected to Address mapping from the public Network 230 to the intranet 210 through the NAT server 220, and then is forwarded to the base station 212 through the UDP/IP, and the base station 212 is sent to the Internet of things device 200 (Internet of things communication module 211).
Since the internet of things platform 231 and the service platform 232 belong to the public network 230, communication can be directly performed through a Transmission Control Protocol (TCP)/Internet Protocol (IP), and the service platform 232 subscribes to the device resource of the internet of things device 200, or receives the device resource of the internet of things device 200 from the service platform 232.
In practical applications, the types of the devices of the Internet of Things are different, and the protocols of the Internet of Things are different, so that those skilled in the art can better understand the embodiments of the present invention, NB-IoT (Narrow Band Internet of Things based on cellular) is described as an example of the devices of the Internet of Things.
In this example, the internet of things platform communicates with the NB-IoT device over RFC7641 protocol to subscribe to device resources of the NB-IoT device.
As shown in fig. 3, after the internet of things device (e.g., NB-IoT device) is started, the internet of things communication module is notified to register, and establishes a wireless connection with the base station, and sends a registration request through the wireless connection.
The base station sends a registration request of the communication module of the Internet of things to the NAT server, and the NAT server carries out address conversion from an internal network to a public network on the registration request and then sends the registration request to the platform of the Internet of things.
And the Internet of things platform authenticates the Internet of things equipment according to the registration request, if the Internet of things equipment is identified as legal equipment, the successful registration is confirmed, and the Internet of things equipment is allowed to access the Internet of things platform.
On the one hand, the internet of things platform sends the successful registration notice to the NAT server, the NAT server performs address conversion from a public network to an intranet on the successful registration notice and then sends the successful registration notice to the base station, the base station sends the successful registration notice to the internet of things communication module through wireless connection, and the internet of things communication module informs the internet of things equipment of completion of registration.
On the other hand, the Internet of things platform sends the online notification to the service platform to notify the Internet of things equipment to register online, and the service platform sends a confirmation message to the service platform after receiving the online notification.
Step 102, if the service platform requests to subscribe the device resource of the internet of things device, generating a target token for the internet of things device.
As shown in fig. 3, after the internet of things device is successfully registered, the internet of things cloud platform notifies the service platform that the internet of things device is online, then monitors the service platform, and waits for a subscription request of the service platform for the interested device resource.
The user can operate on the service platform, select subscribed equipment resources, generate a subscription request according to the TCP/IP, and send the subscription request to the Internet of things platform.
And the Internet of things platform generates a target token of the subscription according to the subscription request.
In one embodiment of the present invention, step 102 may include the following sub-steps:
the substep S11 is used for judging whether a target token generated for the Internet of things equipment in advance is stored; if yes, go to substep S12, otherwise go to substep S13.
And a substep S12, deleting the previously generated target token, and generating the target token for the Internet of things equipment again.
And a substep S13, generating a target token for the Internet of things equipment for the first time.
After the initial registration is successful, for the internet of things device, a resource subscription request message of the internet of things platform is waited for within a preset time period.
In one case, if the resource subscription request message is received within the time period, the internet of things device sends a resource subscription response message to the internet of things platform for confirmation, and at this time, the internet of things device considers that the device resource subscription is successful.
In another case, if the resource subscription request message is not received within the time period, the internet of things device re-registers.
In this case, for the internet of things platform, the internet of things platform has generated the target token, stored in the monitoring table, and sends the resource subscription request message, and the resource subscription request message cannot be sent to the internet of things device due to the transmission problem of the NAT server, the base station, and the like.
And then, when the Internet of things equipment is registered again, a new session is generated with the Internet of things platform again.
The target token is effective in a session between the internet of things platform and the internet of things equipment, so that the internet of things platform can check whether the target token generated for the internet of things equipment in advance is stored in the monitoring table after the internet of things equipment is registered.
If the target token is not registered for the first time, the target token generated in advance is deleted, monitoring of the device resources required to be subscribed by the previous session is stopped, the resources occupied by the Internet of things platform are released, resource consumption is reduced, a new target token is generated for the session again, and the device resources required to be subscribed by the session are monitored.
If not, the Internet of things equipment is registered for the first time, a target token is generated for the session for the first time, and the equipment resources which require subscription for the session are monitored.
Step 103, sending a resource subscription request message carrying the target token and subscribing the device resource to the internet of things device.
In the embodiment of the present invention, the internet of things platform may generate a resource subscription request message (i.e., CoAP Registration message) according to protocols such as RFC7641, and send the resource subscription request message carrying the target token to the internet of things device (e.g., NB-IoT device).
As shown in fig. 3, the internet of things platform sends the resource subscription request message to the NAT server, the NAT server performs address conversion from the public network to the intranet on the resource subscription request message and sends the resource subscription request message to the base station, the base station sends the resource subscription request message to the internet of things communication module through wireless connection, and the internet of things communication module sends a related subscription request to the internet of things device.
And step 104, if a resource subscription response message sent by the internet of things device to the resource subscription request message is not received within a preset time period, determining that the subscription of the device resource is overtime.
And 105, storing the target token according to the waiting overtime of the equipment resource subscription.
After the internet of things platform sends the resource subscription request message, the resource subscription response message sent by the internet of things equipment to the resource subscription request message is waited for in a preset time period.
In general, if the internet of things device receives the resource subscription request message, the resource subscription request message is confirmed, a resource subscription response message (i.e., CoAP 2.xx message) is generated according to RFC7641/7252, the subscription is successful, the message is sent to the internet of things platform, and the target token in the resource subscription request message is stored.
As shown in fig. 3, if the internet of things device confirms the subscription, the internet of things communication module is notified, the internet of things communication module generates a resource subscription response message, the resource subscription response message is sent to the base station through the wireless connection, the base station sends the resource subscription response message to the NAT server, and the NAT server performs address conversion from the intranet to the public network on the resource subscription response message and then sends the address conversion to the internet of things platform.
Therefore, if the internet of things platform does not receive the resource subscription response message of the internet of things device within the time period, the resource waiting timeout of the subscription device occurs, and there may be two cases as follows:
1. and the resource subscription request message of the Internet of things platform is not sent to the Internet of things equipment.
In this case, the internet of things platform has generated the resource subscription request message and sent the resource subscription request message to the internet of things device through the NAT server, the base station, and other devices, and because the NAT server, the base station, and other devices have a problem in transmission, the resource subscription request message is not sent to the internet of things device, and therefore the internet of things device does not generate the resource subscription response message accordingly, and the internet of things platform cannot receive the resource subscription response message.
Because the internet of things equipment is registered again under the condition (step 101), and the internet of things platform subscribes the equipment resource again, the internet of things platform stores the target token and does not influence subsequent subscription.
2. And the resource subscription response message of the Internet of things equipment is not sent to the Internet of things platform.
In this case, the internet of things device has received the resource subscription request message and generated a resource subscription response message, and the resource subscription response message is sent to the internet of things device through the NAT server, the base station, and other devices.
At this time, the internet of things device considers that the subscription is successful, and does not perform registration again (i.e., step 101), and for the internet of things platform, the target token is stored, so that the internet of things platform can still perform correct verification when the internet of things device subsequently uses the target token to report the subscribed device resources.
In the embodiment of the invention, if a service platform requests to subscribe equipment resources of internet of things equipment, a target token is generated for the internet of things equipment, a resource subscription request message carrying the target token and subscribing the equipment resources is sent to the internet of things equipment, if a resource subscription response message sent by the internet of things equipment to the resource subscription request message is not received within a preset time period, the subscription equipment resource is confirmed to be overtime, the target token is stored according to the overtime of the subscription equipment resource, and under the condition that the resource subscription response message generated by the internet of things equipment considers that the subscription is successful but the resource subscription response message is not sent successfully, the internet of things platform considers that the subscription is overtime, the target token is still stored, so that the subscription state of the internet of things equipment and the internet of things platform is kept consistent when communication is abnormal, and equipment resources reported by subsequent internet of things equipment can be, the successful subscription of the device resource is guaranteed.
Referring to fig. 4, a flowchart illustrating steps of another method for subscribing to resources of an internet of things device according to an embodiment of the present invention is shown, and the method specifically includes the following steps:
step 401, registering the internet of things device.
Step 402, if the service platform requests to subscribe the device resource of the internet of things device, generating a target token for the internet of things device.
Step 403, sending a resource subscription request message carrying the target token and subscribing the device resource to the internet of things device.
Step 404, if a resource subscription response message sent by the internet of things device to the resource subscription request message is not received within a preset time period, determining to subscribe to the device resource for timeout.
Step 405, storing the target token according to the timeout waiting of the device resource subscription.
Step 406, generating a subscription timeout message according to the timeout of the device resource subscription.
Step 407, sending the subscription timeout message to the service platform to wait for the subscribed device resource.
In the embodiment of the invention, for the subscription equipment resource waiting overtime, the subscription equipment resource is not considered to be failed, and at the moment, a subscription overtime message can be generated and sent to the service platform through TCP/IP.
After receiving the subscription overtime message, the service platform learns that the subscription equipment resource is overtime, and then continues to wait for the internet of things platform to report the equipment resource subscribed to the internet of things equipment.
Referring to fig. 5, a flowchart illustrating steps of a resource subscription method for an internet of things device according to an embodiment of the present invention is shown, which may specifically include the following steps:
step 501, registering the Internet of things equipment.
Step 502, if the service platform requests to subscribe the device resource of the internet of things device, a target token is generated for the internet of things device.
Step 503, sending a resource subscription request message carrying the target token and subscribing the device resource to the internet of things device.
Step 504, if the resource subscription response message sent by the internet of things device is received within a preset time period, it is confirmed that the device resource subscription is successful.
And 505, storing the target token according to the success of subscribing the equipment resource.
After the internet of things platform sends the resource subscription request message, the resource subscription response message sent by the internet of things equipment to the resource subscription request message is waited for in a preset time period.
If the internet of things platform receives the resource subscription response message of the internet of things equipment in the time period, the success of subscribing the equipment resources can be confirmed, and at the moment, the target token is stored in the monitoring table, so that the internet of things platform can correctly check when the internet of things equipment reports the subscribed equipment resources by using the target token subsequently.
Step 506, generating a subscription success message according to the success of subscribing the device resource.
And 507, sending the successful subscription message to the service platform to wait for the subscribed device resources.
As shown in fig. 3, when the internet of things platform subscribes to the device resource successfully, a subscription success message is generated and sent to the service platform through TCP/IP, so as to confirm the subscription.
After receiving the successful subscription message, the service platform learns that the equipment resource is successfully subscribed, and normally waits for the internet of things equipment to report the subscribed equipment resource.
Referring to fig. 6, a flowchart illustrating steps of a resource subscription method for an internet of things device according to another embodiment of the present invention is shown, and the method specifically includes the following steps:
step 601, registering the Internet of things equipment.
Step 602, if the service platform requests to subscribe the device resource of the internet of things device, a target token is generated for the internet of things device.
Step 603, sending a resource subscription request message carrying the target token and subscribing the device resource to the internet of things device.
Step 604, judging whether a resource subscription response message sent by the internet of things device to the resource subscription request message is received within a preset time period; if yes, go to step 605, otherwise go to step 607.
Step 605, confirming that the subscription of the device resource is successful.
Step 606, storing the target token according to the success of subscribing the device resource.
Step 607, confirming that subscribing to the device resource waits for a timeout.
Step 608, storing the target token according to the timeout of the device resource subscription.
Step 609, receiving a resource subscription notification message sent by the internet of things device.
Step 610, matching the target token with the reference token.
Step 611, when the matching is successful, sending the device resource to the service platform.
As shown in fig. 3, for the requirement of low power consumption of the internet of things device in application scenarios such as NB-IoT, in many cases, the internet of things device enters a sleep state as soon as possible after initialization is completed, and the internet of things device cannot receive data during the sleep period.
For example, in NB-IoT, the internet of things device may sleep in a power saving mode PSM, an extended discontinuous reception eDRX, or the like.
Therefore, the Internet of things equipment completes initialization after being started and before sleeping, the subscription state of the Internet of things equipment and the subscription state of the Internet of things platform are guaranteed to be consistent, and the equipment resources subscribed are normally reported after the Internet of things equipment is awakened.
After the internet of things equipment is awakened, subscribed equipment resources are collected, a resource subscription Notification message (namely, a CoAP Notification message) is generated according to RFC7641/7252, and a certain target token stored in advance is used as a reference token and is sent to the internet of things platform.
The method comprises the steps that the Internet of things platform receives a resource subscription notification message of the Internet of things equipment during operation, wherein the resource subscription notification message comprises equipment resources and a reference token.
And the Internet of things platform extracts the equipment resources and the reference token from the resource subscription notification message and extracts the target token corresponding to the Internet of things equipment from the monitoring table.
For the internet of things platform, the target token may be a target token stored when the resource of the first subscription device waits for timeout, or may be a target token stored when the resource of the first subscription device succeeds, which is not limited in the embodiment of the present invention.
And the Internet of things platform matches the reference token with the target token, if the reference token and the target token are successfully matched, the resource subscription notification message is considered to be legal, and the equipment resource can be sent to the service platform through the TCP/IP.
As shown in fig. 3, if the internet of things device collects the device resource, the device resource can be transmitted to the internet of things communication module, the internet of things communication module packages the device resource into a resource subscription notification message, the resource subscription notification message is sent to the base station through wireless connection, the base station sends the resource subscription notification message to the NAT server, the NAT server performs address conversion from the intranet to the public network on the resource subscription notification message, and sends the resource subscription notification message to the internet of things platform, and the internet of things platform sends the device resource to the service platform after checking the token.
It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention. Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the invention.
