Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

An embodiment of the present invention is applied to an IoT system, and fig. 1 shows an architecture diagram of the IoT system, and as shown in fig. 1, an IoT system 10 includes a Radio Access Network (RAN) 11, a Service Capability Exposure Function (SCEF)system 12, a Mobility Management Entity (MME) 13, and a terminal 14. The terminal performs periodic information interaction with a Mobility Management Entity (MME) through an ATTACH signaling (ATTACH) and a Tracking Area Update (TAU) signaling message of a signaling plane, and reports identity information, network information, and service information of the terminal side. The MME integrates the information reported by the terminal and the information of the MME, and then shares data with a Service Capability Exposure Function (SCEF). The MME provides an Application Programming Interface (API) query Interface and a subscription notification API Interface for the SCEF to call.

In the embodiment of the present invention, the SCEF includes an information opening module, and has the API capabilities shown in table 1:

TABLE 1

The SCEF supports identity information, network information and service information query capability, and when an IoT platform query request is received, a query result is returned to the IoT platform through a response message. The SCEF supports an information subscription capability, and supports subscription of identity class information, network class information and service class information of the terminal from the IoT platform. The SCEF supports calling an information reporting API to notify the IoT platform when receiving the MME subscription event notification.

The IoT Platform comprises an information storage open module, acquires data from the SCEF through a southbound interface and stores the data in an information open database, and then opens the data to a third party Application program for use through an AEP (Application Enablement Platform) interface. The information open database model is shown in table 2:

the third party application may obtain terminal and network information from the IoT platform through a query flow or a subscription notification flow. The following describes the detailed flow of information query and information subscription notification.

Fig. 2 shows a flowchart of an internet of things information query method provided by the embodiment of the invention. As shown in fig. 2, the method includes:

step 201: the application initiates an information query request to the IoT platform.

In this step, the application program is a third party application program.

Step 202: the IoT platform pre-answer application.

In this step, the IoT platform receives the information query request sent by the application program, and pre-responds to the application program, indicating that the request has been received and is being processed.

Step 203: and the IoT platform performs access validity authentication on the application program.

Step 204: and after the authentication is passed, the IoT platform determines whether the information queried by the application program already exists in the information open database, if so, step 208 is executed, otherwise, step 205 is executed.

In this step, the IoT platform performs logic processing on data acquisition, determines whether the data to be acquired is existing data or data that needs to initiate query, and determines a data query mode, which is SCEF query or terminal query, according to the terminal type and the application program requirement.

Step 205: the IoT platform initiates a data query request to the SCEF or terminal.

If no data exists in the information open database, the IoT platform needs to initiate a data query request to the SCEF or the terminal. In this step, the IoT platform may further determine, according to different terminal types and application requirements, whether to query the information by the SCEF or directly establish the user plane connection with the terminal to obtain the information. For example, for some terminals intermittently accessing the network:

if some service data change slowly (for example, less than a preset threshold value) and do not need to be updated in real time (for example, a table lookup terminal or the like), the IoT directly selects the SCEF to return the query result when the application queries;

if the service data of the terminal is changed quickly (for example, greater than or equal to the preset threshold) and needs to be updated in real time (for example, the location of the logistics terminal is changed), a connection with the terminal needs to be established to obtain corresponding data in order to avoid the non-latest SCEF data during the query of the application program. In this case, the IoT platform may also first query, by the SCEF, whether there is service data that satisfies the preset time limit (e.g., does not exceed X branches), and if so, return the query result, and if not, establish connection with the terminal to obtain information.

By the method, when the application program acquires the terminal and the network information from the IoT platform, the IoT platform can select to establish the user plane connection with the terminal or acquire data through the SCEF according to the type of the terminal and the application requirement, so that the IoT platform can reasonably utilize the SCEF data and can acquire accurate data through the terminal user plane connection in time according to various terminals and various application program requirements.

Step 206: the SCEF initiates a data query request to the MME.

Step 207: and the MME returns a data query result to the SCEF.

Step 208: the SCEF or terminal returns the data query result to the IoT platform.

When the IoT platform initiates a data query request to the SCEF, returning a data query result to the IoT platform by the SCEF; and when the IoT platform initiates a data query request to the terminal, returning a data query result to the IoT platform by the terminal.

At step 209, the IoT platform returns the data query result to the application.

According to the embodiment of the invention, the information opening system architecture suitable for the Internet of things is constructed, the information opening module is designed in the SCEF, the networking terminal and the network information are supported to be opened to the outside, the information storage opening module and the information opening database are constructed in the IoT platform, the application program uniformly acquires the terminal and the network information from the IoT platform, the end-to-end opening of the Internet of things information is realized, and the information opening process does not need to periodically establish user plane bearing, so that the power consumption of the terminal is reduced, and the network overhead is reduced.

The terminal does not need to periodically and actively establish user interface connection to send information, so that the power consumption of a terminal battery can be reduced; the wireless access network does not need to periodically establish and release user plane bearer, and can effectively reduce network overhead; the IoT platform deeply participates in the collection, integration and storage of the information of the Internet of things, and is opened to the outside for the application program, so that the value of the platform can be fully improved.

Fig. 3 shows a flowchart of an internet of things information subscription method provided by an embodiment of the present invention. As shown in fig. 3, the method includes:

step 301: the application initiates an information subscription request to the IoT platform.

Step 302: the IoT platform pre-answer application.

In this step, the IoT platform receives the information subscription request sent by the application program, and responds to the application program in advance, indicating that the request has been received and is being processed.

Step 303: and the IoT platform authenticates the access validity of the application program, and generates and stores subscription rules.

Step 304: the IoT platform issues subscription rules to the SCEF, and the SCEF is required to report data according to the rules.

Step 305: the SCEF issues a subscription rule to the MME and requests the SCEF to report data according to the rule.

Step 306: the MME returns the subscription result to the SCEF.

Step 307: the SCEF returns the subscription result to the IoT platform.

Step 308: the IoT platform stores an application and subscription rule information corresponding to the application.

Step 309: the IoT platform returns the subscription result to the application.

Fig. 4 shows a flowchart of an information notification method of the internet of things according to an embodiment of the present invention, because the notification is initiated based on a subscription, the notification method may also be counted as a part of the subscription method according to the above embodiment. As shown in fig. 4, the method includes:

step 401: and the MME judges that the terminal and the network data are changed and sends a notification message to the SCEF.

Step 402: the SCEF forwards the notification message to the IoT platform.

Step 403: and the IoT platform detects the validity of the data and then stores the data.

Step 404: the IoT platform sends a notification response message to the SCEF.

Step 405: the SCEF forwards the notification response message to the MME.

Step 406: the IoT platform decides whether to send data to the application according to the subscription rules.

Step 407: if so, the IoT platform sends a notification message to the application.

Step 408: the application sends a notification response message to the IoT platform.
