Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a data transmission system, method and network element equipment for passive Internet of Things terminals. Background Art

[0002] With the development of Internet of Things technology, how to enable more devices to access the Internet of Things has become an urgent problem to be solved. Existing Internet of Things devices are divided into two types. One is active Internet of Things devices, which are generally equipped with SIM cards (Subscriber Identity Module) and have the ability to independently access the 3GPP (3rd Generation Partnership Project) core network, but the manufacturing cost of such devices is relatively high, and the use and maintenance costs are also relatively high. The other is passive Internet of Things devices, which are not equipped with SIM cards and have extremely low power consumption, but because they do not have SIM cards, they do not have the ability to directly access the 3GPP core network.

[0003] Currently, if passive IoT devices need to be connected to the 3GPP core network, a relay with 3GPP core network access capability needs to be deployed in the usage scenario so that the passive IoT devices and the network can provide services to each other. However, although the existence of relays expands the scope of use of passive IoT terminals, it also objectively limits the ability of the 3GPP core network to directly provide services to passive IoT terminals. Therefore, it is necessary to provide a solution that enables passive IoT terminals to directly access the 3GPP core network. Summary of the invention

[0060] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0061] like Figure 1 As shown, the embodiment of the present application provides a data transmission system 10 for a passive IoT terminal. The data transmission system 10 includes an Ambient IoT Data Store and Processing Function (ADSPF) 100, a Radio Access Network (RAN) 200, a Network Exposure Function (NEF) 300, and an Application Function (AF) 400. The Passive IoT Terminal Data Storage and Processing Module 100 is connected to the Radio Access Network Module 200, the Network Exposure Module 300, and the Application Module 400, respectively. The wireless access network module 200 is used to receive the reported data sent by each passive Internet of Things terminal 500, and send each reported data to the passive Internet of Things terminal data storage and processing module 100, the reported data includes the terminal identification of the passive Internet of Things terminal and the storage data of the passive Internet of Things terminal (Ambient UE / Ambient IoT) 500; the passive Internet of Things terminal data storage and processing module 100 is used to receive each reported data, summarize and process each reported data, obtain summarized data, and share the summarized data.

[0062] The wireless access network module 200 may be a base station in a 3GPP network. After collecting data, the passive IoT terminal 500 regularly assembles the data into reporting data and sends it to the wireless access network module 200; or, the passive IoT terminal 500 may also send the reporting data to the wireless access network module 200 when receiving a broadcast sent by the wireless access network module 200 or other modules in the 3GPP network. The reporting data is composed of the terminal identification of the passive IoT terminal 500 and the data stored in the passive IoT terminal 500. The terminal identification is a unique identification of each passive IoT terminal 500. The terminal identification and the stored data can be obtained by the passive IoT terminal 500 from its own storage module.

[0063] After acquiring the reported data sent by each passive Internet of Things terminal, the wireless access network module 200 forwards the reported data to the passive Internet of Things terminal data storage and processing module 100. The passive Internet of Things terminal data storage and processing module 100 stores the reported data and performs summary processing on the reported data. The summary processing may refer to classifying, screening and partial preprocessing of the reported data. The passive Internet of Things terminal data storage and processing module 100 may then share the summary data obtained after the summary processing with other modules in the 3GPP network. For example, the passive Internet of Things terminal data storage and processing module 100 may send the summary data to the network open module 300, and the network open module 300 may then share the summary data with other modules. Alternatively, the passive Internet of Things terminal data storage and processing module 100 may also share the summary data with the application module 400 in response to a request from the application module 400. The embodiments of the present application do not specifically limit this.

[0064] It should be noted that the passive IoT terminal data storage and processing module 100 can also establish a connection with the application module 400 through the user plane module (User Plane Function, UPF). That is, the passive IoT terminal data storage and processing module 100 can be connected to the user plane module, and the user plane module is further connected to the application module 400; when the passive IoT terminal data storage and processing module 100 needs to send summary data to the application module 400, the summary data can be sent to the user plane module, and then the user plane module forwards the summary data to the application module 400, and the embodiment of the present application does not specifically limit this.

[0065] The data transmission system for passive IoT terminals provided in the embodiment of the present application adds a passive IoT terminal data storage and processing module in the 3GPP network, so that each passive IoT terminal does not need to access the 3GPP network through a relay, and can upload data to the passive IoT terminal data storage and processing module. The passive IoT terminal data storage and processing module is responsible for aggregating the data and sharing the aggregated data with other modules in the 3GPP network, thereby realizing direct communication between the passive IoT terminal and the 3GPP network.

[0066] In one embodiment, the data transmission system 10 further includes a passive IoT terminal 500, which is used to obtain storage data and terminal identification from the storage module, and send the terminal identification and storage data as reporting data to the wireless access network module 200.

[0067] In the embodiment of the present application, when the passive Internet of Things terminal 500 needs to assemble the reported data, it can obtain the terminal identification and the previously stored storage data from the storage module. The stored data can be all the data stored in the passive Internet of Things terminal, or it can be part of the data, such as a specific type of data required in the broadcast, or the passive Internet of Things terminal 500 The data newly collected after reporting data to the wireless access network module 200 last time, etc., the embodiment of the present application does not specifically limit this.

[0068] The passive Internet of Things terminal 500 may package the terminal identification and the stored data into a data packet and send the data packet to the wireless access network module 200. Alternatively, the passive Internet of Things terminal 500 may not perform a packaging operation and directly send the terminal identification and the stored data as reported data to the wireless access network module 200, which is not specifically limited in the embodiment of the present application.

[0069] The data transmission system for passive Internet of Things terminals provided in the embodiment of the present application enables the passive Internet of Things terminals to send terminal identification and storage data as reported data to the wireless access network module, which can minimize the amount of data reported by the passive Internet of Things terminals and reduce the energy consumption of the passive Internet of Things terminals in reporting data.

[0070] In one embodiment, the passive Internet of Things terminal data storage and processing module 100 is also used to send a data reporting request to the wireless access network module 200; the wireless access network module 200 is also used to respond to the data reporting request and send a data reporting request broadcast, and the data reporting request broadcast is used to instruct the passive Internet of Things terminal 500 to feedback the reporting data.

[0071] In the embodiment of the present application, when the passive Internet of Things terminal 500 receives the data reporting request broadcast sent by the wireless access network module 200, it sends the reporting data to the wireless access network module 200, and does not actively report the data when the data reporting request broadcast is not received. The passive Internet of Things terminal data storage and processing module 100 can control the sending time of the data reporting request broadcast. When the passive Internet of Things terminal data storage and processing module 100 needs to collect data, the passive Internet of Things terminal data storage and processing module 100 sends the data reporting request to the wireless access network module 200. After receiving the data reporting request, the wireless access network module 200 sends the data reporting request broadcast, and then forwards the reporting data sent by each passive Internet of Things terminal 500 in response to the data reporting request broadcast to the passive Internet of Things terminal data storage and processing module 100.

[0072] The data transmission system for passive Internet of Things terminals provided in the embodiment of the present application can control the time for each passive Internet of Things terminal to report data by instructing each passive Internet of Things terminal to report data by enabling the wireless access network module to send a data reporting request broadcast.

[0073] In one embodiment, the passive IoT terminal data storage and processing module 100 is also used to periodically send data reporting requests to the wireless access network module 200 , and after obtaining the aggregated data, share the aggregated data with the network open module 300 .

[0074] In the embodiment of the present application, the passive IoT terminal data storage and processing module 100 can periodically request data from the wireless access network module 200, and after summarizing and processing the reported data returned by the wireless access network module 200, send the summarized data to the network open module 300, so that other modules in the 3GPP network can also obtain the summarized data. Among them, the period of sending data reporting requests can be set by those skilled in the art according to actual needs, and the embodiment of the present application does not specifically limit this.

[0075] The data transmission system for passive Internet of Things terminals provided in the embodiment of the present application enables the data storage and processing module of the passive Internet of Things terminal to periodically send data reporting requests to the wireless access network module, so that the wireless access network module periodically sends data reporting request broadcasts, and can periodically collect the reporting data of each passive Internet of Things terminal.

[0076] In one embodiment, the application module 400 is also used to send a data acquisition request to the passive Internet of Things terminal data storage and processing module 100; the passive Internet of Things terminal data storage and processing module 100 is also used to send the reported data in the storage module to the application module 400 when the reported data in the storage module meets the data acquisition request.

[0077] In the embodiment of the present application, the application module 400 can actively request data from the passive Internet of Things terminal data storage and processing module 100. When the passive Internet of Things terminal data storage and processing module 100 receives the data acquisition request, it determines whether the reported data stored in its own storage module meets the data acquisition request. The reported data meets the data acquisition request, which means that there is a sufficient number of reported data in the storage module that meets all the requirements specified by the data acquisition request. For example, if the data acquisition request requires 100 data collected within a specific time period, when there are more than 100 data collected within the time period in the storage module, it can be considered that the reported data in the storage module meets the data acquisition request.

[0078] In the case where the reported data in the storage module meets the data acquisition request, the passive Internet of Things terminal data storage and processing module 100 can return the data required by the data acquisition request to the application module 400. It should be noted that the passive Internet of Things terminal data storage and processing module 100 can simultaneously perform periodic data collection and aggregation when receiving the data acquisition request and sending the summary data to the application module 400. Therefore, in the case where the reported data in the storage module does not meet the data acquisition request (for example, when the data acquisition request requires a specific amount of data, the amount of data in the storage module is insufficient), the passive Internet of Things terminal data storage and processing module 100 can first send all the data in the storage module that meets the data acquisition request to the application module 400, and at the next periodic data collection, determine whether there is reported data that meets the data acquisition request in the newly collected data; if so, send this part of the reported data to the application module 400 until all the sent data have completely met the data acquisition request.

[0079] The data transmission system for passive Internet of Things terminals provided in the embodiment of the present application enables the data storage and processing module of the passive Internet of Things terminal to check whether the data stored in the storage module meets the requirements when receiving the data acquisition request of the application module. If so, the data is returned to the application module, and the application module can be allowed to actively request data from the data storage and processing module of the passive Internet of Things terminal.

[0080] In one embodiment, the passive Internet of Things terminal data storage and processing module 100 is also used to send a data reporting request to the wireless access network module 200 when the reported data in the storage module does not meet the data acquisition request; the passive Internet of Things terminal data storage and processing module 100 is also used to integrate the summary data with the reported data in the storage module to obtain integrated data, and send the integrated data to the application module 400.

[0081] In the embodiment of the present application, when the reported data in the storage module does not satisfy the data acquisition request, the passive Internet of Things terminal data storage and processing module 100 may request data once from the wireless access network module 200. When the passive Internet of Things terminal data storage and processing module 100 sends a data reporting request to the wireless access network module 200, the wireless access network module 200 sends a data reporting request broadcast in response to the data reporting request, and forwards the reported data sent by each passive Internet of Things terminal 500 in response to the data reporting request broadcast to the passive Internet of Things terminal data storage and processing module 100.

[0082] The passive IoT terminal data storage and processing module 100 aggregates the reported data, distinguishes the data that meets the data acquisition request from the aggregated data, and distinguishes the data that meets the data acquisition request from the reported data in the storage module. After the two parts of data are integrated, the integrated data obtained by integration is sent to the application module 400.

[0083] It should be noted that if the integrated data cannot fully satisfy the data acquisition request (for example, the quantity is still less than the quantity specified in the data acquisition request), the passive Internet of Things terminal data storage and processing module 100 may request data from the wireless access network module 200 again after a certain period of time, so as to continue to distinguish the data that satisfies the data acquisition request from the newly obtained summary data and integrate the integrated data until the integrated data fully satisfies the data acquisition request. Alternatively, the passive Internet of Things terminal data storage and processing module 100 may first send the integrated data to the application module 400, and then obtain the data that meets the data acquisition requirements in the collected summary data in the periodic data collection, and send this part of the data to the application module 400 until all the sent data have fully satisfied the data acquisition request.

[0084] The data transmission system for passive Internet of Things terminals provided in the embodiment of the present application enables the data storage and processing module of the passive Internet of Things terminal to request data from the wireless access network module when the data stored in the storage module does not meet the requirements, so that the data storage and processing module of the passive Internet of Things terminal can return complete data that meets the data acquisition request to the application module.

[0085] In one embodiment, the passive Internet of Things terminal data storage and processing module 100 is also used to generate a data reporting request based on the data acquisition request when the reported data in the storage module does not meet the data acquisition request; the passive Internet of Things terminal 500 is also used to respond to the data reporting request broadcast and obtain storage data matching the data acquisition request from the storage module.

[0086] In the embodiment of the present application, when the passive Internet of Things terminal data storage and processing module 100 receives a data acquisition request and requests data from the wireless access network module 200 based on the data acquisition request, it can specify through a data reporting request that it only needs to obtain data that matches the requirements of the data acquisition request; the wireless access network module 200 then sends a data reporting request broadcast based on the data reporting request, and after receiving the data reporting request broadcast, the passive Internet of Things terminal 500 obtains the storage data that matches the data acquisition request from the storage module according to the instructions of the data reporting request broadcast, and returns this part of the storage data and the terminal identifier as the reported data to the wireless access network module 200, and the wireless access network module 200 then forwards the received reported data to the passive Internet of Things terminal data storage and processing module 100, so that the passive Internet of Things terminal data storage and processing module 100 can summarize and process the reported data, integrate the obtained summarized data with the data in the storage module of the passive Internet of Things terminal data storage and processing module 100, and send the finally obtained integrated data to the application module 400.

[0087] The data transmission system for passive Internet of Things terminals provided by the embodiment of the present application enables the data storage and processing module of the passive Internet of Things terminal to generate and send a data reporting request to the wireless access network module based on the data acquisition request when the data stored in the storage module does not meet the requirements, so that the passive Internet of Things terminal can ultimately only report the data that matches the data acquisition request, saving the cost of reporting data by the passive Internet of Things terminal.

[0088] In one embodiment, Figure 2 As shown, a data transmission method for a passive Internet of Things terminal is provided, and the method is applied to a data storage and processing module of a passive Internet of Things terminal, comprising the following steps:

[0089] Step 202, receiving the reported data sent by the wireless access network module, the reported data is data sent by the passive Internet of Things terminal to the wireless access network module, and the reported data includes the terminal identifier of the passive Internet of Things terminal and the data stored in the passive Internet of Things terminal.

[0090] Step 204, summarize the reported data to obtain summary data.

[0091] Step 206: Share the summary data.

[0092] In the embodiment of the present application, the wireless access network module can be a base station in the 3GPP network. When the passive Internet of Things terminal needs to report data, it sends its own terminal identification and stored data as reported data to the wireless access network module, and the wireless access network module then forwards the reported data to the passive Internet of Things terminal data storage and processing module. The passive Internet of Things terminal data storage and processing module performs pre-processing such as classification, screening, and data desensitization on the reported data to obtain summary data, and then sends the summary data to other modules in the 3GPP network to share and process the summary data. Among them, the specific operations performed by each module can be found in the relevant description of the aforementioned embodiment, and the embodiment of the present application will not be repeated here.

[0093] The data transmission method for passive Internet of Things terminals provided in the embodiment of the present application adds a passive Internet of Things terminal data storage and processing module in the 3GPP network, so that each passive Internet of Things terminal does not need to access the 3GPP network through a relay, and can upload data to the passive Internet of Things terminal data storage and processing module. The passive Internet of Things terminal data storage and processing module is responsible for aggregating the data and sharing the aggregated data with other modules in the 3GPP network, thereby realizing direct communication between the passive Internet of Things terminal and the 3GPP network.

[0094] In one embodiment, before step 202, the method further includes:

[0095] A data reporting request is sent to the wireless access network module, where the data reporting request is used to instruct the wireless access network module to send a data reporting request broadcast, where the data reporting request broadcast is used to instruct the passive Internet of Things terminal to feedback the reporting data.

[0096] In the embodiment of the present application, the passive IoT terminal will send the reported data only when receiving the data report request broadcast. The passive IoT terminal data storage and processing module can send a data report request to the wireless access network module to instruct the wireless access network module to send the data report request broadcast.

[0097] Reference Figure 4As shown, there are two situations in which the passive Internet of Things terminal data storage and processing module sends a data reporting request. The application module can send a data acquisition request to the passive Internet of Things terminal data storage and processing module, and the passive Internet of Things terminal data storage and processing module checks whether the data stored in its own storage module meets the requirements of the data acquisition request. If it meets the requirements, the passive Internet of Things terminal data storage and processing module sends the data stored in itself to the application module; if it does not meet the requirements, the passive Internet of Things terminal data storage and processing module can send a data reporting request to the wireless access network module once, so that the wireless access network module sends a data reporting request broadcast, indicating that all passive Internet of Things terminals within the range return data to the wireless access network module. The wireless access network module then forwards the data to the passive Internet of Things terminal data storage and processing module, and the passive Internet of Things terminal data storage and processing module returns the data it needs to the application module.

[0098] Alternatively, the passive IoT terminal data storage and processing module can also actively and periodically send data reporting requests to the wireless access network module, so that the wireless access network module periodically sends data reporting requests to broadcast and collect data. The passive IoT terminal data storage and processing module can then send the aggregated data to the network open module, and the network open module shares the data with other modules in the 3GPP network.

[0099] The data transmission system for passive Internet of Things terminals provided in the embodiment of the present application can control the time for each passive Internet of Things terminal to report data by instructing each passive Internet of Things terminal to report data by enabling the wireless access network module to send a data reporting request broadcast.

[0100] In one embodiment, Figure 4 As shown, a data transmission method for a passive Internet of Things terminal is provided, and the method is applied to the passive Internet of Things terminal, comprising the following steps:

[0101] Step 402, obtaining storage data and terminal identification from the storage module.

[0102] Step 404: Use the terminal identification and storage data as reporting data.

[0103] Step 406, sending the reported data to the wireless access network module, so that the wireless access network module sends the reported data to the passive Internet of Things terminal data storage and processing module, and the passive Internet of Things terminal data storage and processing module summarizes the reported data, and after obtaining the summarized data, shares the summarized data.

[0104] In the embodiment of the present application, the wireless access network module may be a base station in a 3GPP network.
