[0062] Figure 9 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application.

[0063] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0064] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0065] Figure 1 This is a schematic diagram illustrating an application scenario provided by an embodiment of this application. Please refer to [link / reference]. Figure 1 It includes multiple AIoT devices 101, intermediate nodes 102 and servers 103.

[0066] AIoT device 101 can be a passive IoT device that does not rely on batteries or other traditional power sources. It can obtain the required power through environmental energy harvesting (e.g., solar energy, thermal energy, vibration energy, or radio frequency energy). AIoT device 101 can access the core network elements of the 3GPP system through intermediate node 102, and AIoT data of AIoT device 101 can be stored in server 103 through intermediate node 102.

[0067] The intermediate node 102 can be a user equipment (UE) or a base station. The intermediate node 102 can receive AIoT data from the first AIoT device 101, obtain the tag information of the first AIoT device 101, and determine the data stream information of the first AIoT device 101 in the tag information. It can determine whether there is a target session corresponding to the data stream information. If so, it can send AIoT data to the server 103 through the target session.

[0068] In existing technologies, AIoT devices can send AIoT data to an intermediate node (IN), which can then establish a target session corresponding to the AIoT device and store the AIoT data in a target server through the target session. However, in passive IoT, with the increasing number of AIoT devices, establishing a corresponding target session for each AIoT device results in a heavy load on the intermediate node.

[0069] The data transmission method provided in this application embodiment can obtain the tag information of the first AIoT device, determine the data stream information of the first AIoT device based on the tag information, and send AIoT data through the target session if there is a target session corresponding to the data stream information. This can realize the transmission of AIoT data with the same data stream information in the same target session, and reduce the load on intermediate nodes.

[0070] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0071] Figure 2 This is a schematic flowchart illustrating a data transmission method provided in an embodiment of this application. Please refer to... Figure 2 The method may include:

[0072] S201, Receive AIoT data from the first AIoT device.

[0073] The execution entity in this application embodiment can be an intermediate node or a data transmission device set in the intermediate node. The data transmission device can be implemented by software or by a combination of software and hardware.

[0074] After establishing a communication connection between the intermediate node and the first AIoT device, the intermediate node can receive AIoT data from the first AIoT device.

[0075] S202. Obtain the tag information corresponding to the first AIoT device.

[0076] Data flow information can be configured in the tag information by configuring policy rules, and the configuration policy rules corresponding to the first AIoT device can be stored in the intermediate node.

[0077] The identification information can be an Electronic Product Code (EPC) label.

[0078] The configuration policy rules also include routing information, which can be defined by the routing descriptor in the traffic descriptor of the User Equipment Route Selection Policy (URSP) information.

[0079] The data flow information of the first AIoT device can be defined through EPC data flow descriptors. The EPC data flow descriptor can define a new type in the Traffic descriptor of the URSP rule information.

[0080] In this process, the configuration policy rules of the first AIoT device can be updated, created, or deleted in the intermediate node. The first AIoT device can send information according to the configuration policy rules, and the intermediate node can extract the information sent by the first AIoT device according to the configuration policy rules.

[0081] In addition, the execution process of updating / creating / deleting the configuration policy rules of the first AIoT device can be found in the following examples, which will not be repeated here.

[0082] S203. According to the configuration strategy rules, obtain the data stream information of the first AIoT device from the tag information.

[0083] Data flow information may include at least one object identifier. At least one object type corresponding to the data flow rule can be obtained from the configuration policy rule. The data flow information is then matched with the tag information based on the at least one object type, and the string corresponding to each object type is determined as the data flow information.

[0084] The object identifier can be an enterprise identifier, industry identifier, product type identifier, date identifier, encoding method, or object identifier, etc.

[0085] For example, multiple AIoT devices can correspond to different industries, and the AIoT data of each industry's AIoT devices has its corresponding encoding format. The industry identifier corresponding to each AIoT device and the encoding format of the data corresponding to the industry identifier can be determined in the data stream information. AIoT data can be classified through the data stream information.

[0086] The same AIoT data stream information can be transmitted within the same session, which can reduce the number of sessions built by intermediate nodes and thus reduce the load on intermediate nodes.

[0087] For example, suppose that at least one object identifier in the data stream information may include an industry identifier, an encoding method, and an object identifier. Suppose that the data stream information of AIoT device 1 is industry identifier 1, encoding method 1, and object identifier 1. Suppose that the data stream information of AIoT device 3 is industry identifier 2, encoding method 2, and object identifier 2. Suppose that before the current moment, the intermediate node has established session 1 corresponding to AIoT device 1. Suppose that at the current moment, AIoT device 2 transmits data through the intermediate node, then AIoT data of AIoT device 2 can be transmitted through session 1.

[0088] Among them, industry identifiers can be Serial Shipping Container Code (SSCC), Serialized Global Trade Item Number (SGTIN), or Global Returnable Asset Identifier (GRAI).

[0089] The encoding methods corresponding to SSCC can be SSCC-96 and SSCC+.

[0090] Furthermore, an object identifier can be defined for each industry identifier, which can be used to indicate the enterprise identifier corresponding to the AIoT device.

[0091] Furthermore, for any given object identifier, that object identifier can correspond to at least one item type (ItemReference).

[0092] For example, assuming the industry identifier is industry identifier 1, industry identifier 1 can also correspond to 4 object identifiers, namely object identifier 1-4. Assuming there are 3 product types, namely product type 1-3, then each object identifier corresponds to 3 product types, and so on. The data flow information can be "industry identifier 1, encoding method 1, object identifier 2, product type 4".

[0093] S204. Determine whether there is a target session corresponding to the data stream information.

[0094] The target session can be a Protocol Data Unit (PDU) session, which allows user devices to communicate with the data network and establish a data transmission channel.

[0095] Intermediate nodes can establish multiple sessions, and each session can encapsulate and transmit AIoT data corresponding to its data stream information.

[0096] Based on the data stream information, it can be determined whether there is a target session corresponding to AIoT data in multiple sessions.

[0097] Specifically, the data stream information corresponding to each session can be compared with the data stream information corresponding to the AIoT device. If the data stream information corresponding to a session is the same as that corresponding to the AIoT device, then the session is identified as the target session.

[0098] S205. If so, send AIoT data through the target session.

[0099] Furthermore, based on the data stream information, the IP address of the target server corresponding to the first AIoT device can be generated; based on the IP address, AIoT data can be sent to the target server through the target session.

[0100] The target server's IP address can be generated as follows: A fully qualified domain name (FQDN) corresponding to the first AIoT device can be constructed using data stream information; a domain name query request is generated based on the FQDN and sent to the domain name system; the IP address sent by the domain name system is received.

[0101] An IP address can be determined by the Domain Name System (DNS) based on a domain name query request.

[0102] FQDN can be a network identifier used to uniquely identify a host on the Internet. The Domain Name System (DNS) can be the naming system used by the Internet and can be used to translate the FQDN of a host used by a user into an IP address.

[0103] The domain name query request may include the FQDN. After receiving the domain name query request, the DNS can generate the IP address of the target server based on the FQDN and send the IP address of the target server to the intermediate node. Then, the intermediate node can obtain the IP address of the target server.

[0104] For example, assuming the data flow information is "Industry Identifier 1, Encoding Method 1, Object Identifier 1", the FQDN can be determined as "Object Identifier 1.Encoding Method 1.Industry Identifier 1.epc". The DNS can generate the target server's IP address as address 1 based on "Object Identifier 1.Encoding Method 1.Industry Identifier 1.epc".

[0105] Below, in conjunction with Figure 3 The interactive process for obtaining the IP address of the target server provided in the embodiments of this application will be described.

[0106] Figure 3 This is an interactive diagram illustrating an embodiment of the present application for determining an IP address. Please refer to [link / reference]. Figure 3This can include a first AIoT device, an intermediate node (IN), a DNS, and a server. The intermediate node can receive AIoT data from the first AIoT device, obtain the tag information of the first AIoT device, and retrieve data stream information from the tag information according to configured policy rules. The intermediate node can construct an FQDN based on the data stream information and generate a domain name query request based on the FQDN. It can send a domain name query request to the DNS, which can determine the IP address of the target server based on the domain name query request. The intermediate node can then obtain the IP address of the target server sent by the DNS.

[0107] Below, in conjunction with Figure 4 This application describes the information interaction process provided in the embodiments of the present application when a target session corresponding to existing data stream information already exists.

[0108] Figure 4 This is an interactive diagram illustrating the determination of a target session, provided as an embodiment of this application. Please refer to... Figure 4 This can include a first AIoT device, an intermediate node (IN), and a server. The intermediate node can receive AIoT data from the first AIoT device. According to the configured policy rules, the intermediate node can determine the data stream information from the tag information of the first AIoT device. If a target session corresponding to the data stream information already exists, the intermediate node can transmit the AIoT data to the server's IP address through the established target session.

[0109] S206. If not, then establish a target session for AIoT data of the first AIoT device, and send AIoT data through the target session.

[0110] Furthermore, the routing information of the first AIoT device can be obtained from the configuration policy rules based on the data flow information. Based on the routing information, a session establishment request can be sent to the Session Management Function (SMF). The target session can be received from the SMF, and the target session can be constructed by the SMF based on the session establishment request.

[0111] SMF can be used to implement session management, supporting the creation, modification, and release of sessions.

[0112] Routing information may include one or more of the following: Session and Service Continuity Mode (SSC Mode) for establishing a session, Single Network Slice Selection Assistance Information (S-NSSAI), and Data Network Name (DNN).

[0113] The session establishment request can include routing information. After receiving the session establishment request, SMF can establish the target session based on the routing information.

[0114] Below, in conjunction with Figure 5 This application describes the information interaction process provided in the embodiments of the present application when there is no target session corresponding to the data stream information.

[0115] Figure 5 This is another interactive diagram illustrating the determination of a target session, provided as an embodiment of this application. Please refer to... Figure 5 This process can include a first AIoT device, an intermediate node (IN), an SMF (Service Provider Framework), and a server. The intermediate node receives AIoT data from the first AIoT device. Based on configuration policy rules, the intermediate node determines the data flow information from the AIoT device's tag information. If a target session corresponding to the data flow information does not exist, it can obtain routing information from the configuration policy rules based on the data flow information. The intermediate node can then initiate a process to establish a target session with the SMF using the routing information. The AIoT data is then transmitted through this target session.

[0116] The data transmission method provided in this application embodiment can obtain the configuration policy rules corresponding to the first AIoT device, obtain the routing selection information of the first AIoT device through the configuration policy rules, and send AIoT data through the target session if there is a target session corresponding to the routing selection information. This can realize the transmission of AIoT data with the same data flow information in the same target session, which can reduce the load of intermediate nodes.

[0117] Based on the above embodiments, the following is combined with Figure 6 and Figure 7 The process of constructing, updating, or deleting the configuration policy rules provided in the embodiments of this application is described.

[0118] Figure 6 This is a flowchart illustrating a process for determining configuration policy rules, as provided in an embodiment of this application. Please refer to [link / reference]. Figure 6 The method may include:

[0119] S601, Receive the configuration policy rules corresponding to the service operation request sent by the policy control function PCF.

[0120] Configuration policy rules can be created, updated, or deleted by the Policy Control Function (PCF) based on service operation requests sent by the Application Function (AF).

[0121] The AF can send service operation requests to the Network Exposure Function (NEF), which in turn sends the service operation requests to the Unified Data Management (UDM). The UDM then authorizes and authenticates the service operation requests. Once authorized and authenticated, the service operation is executed in the Unified Data Repository (UDR), and the UDR sends the configuration policy rules corresponding to the service operation requests to the PCF.

[0122] AF is a key component in the 3GPP architecture, responsible for interacting with other components in the 5G core network to provide specific application services. AF can manage and control AIoT devices, optimize data transmission and processing strategies, and dynamically adjust services based on real-time data.

[0123] NEF can provide a secure and standardized way for third-party applications and services to access and utilize network functions and data. Through NEF, AIoT devices and platforms can access network functions such as device management, data transmission, and event notification, thereby enabling more efficient IoT services.

[0124] It is worth noting that NEF can also send the Generic Public Subscription Identifier (GPSI) and PLMN network identifier to the UDM. The PLMN network identifier can be a mapping of the Extended Group Identifier of the node identifier through the intermediate node.

[0125] Unified Data Management (UDM) can be used to manage and control data information, while Unified Data Repository (UDR) can be used to provide and store data information. User information can include configuration policy rules for AIoT devices.

[0126] Service operation requests can be authorized and authenticated in UDR through UDM. The content of authorization and authentication can include AIoT devices, the requested AF, and the service operation.

[0127] Service operation requests can be used to request intermediate nodes to perform the corresponding service operations. These service operations can include creating configuration policy rules, updating configuration policy rules, or deleting configuration policy rules.

[0128] If the service operation is to create a configuration policy rule, the configuration policy rule corresponding to the service operation request can be created and stored in the UDR. If the service operation is to update a configuration policy rule, the configuration policy rule corresponding to the service operation request can be updated in the UDR. If the service operation is to delete a configuration policy rule, the configuration policy rule corresponding to the service operation request can be deleted in the UDR.

[0129] The Policy Control Function (PCF) is a key network element in the 5G core network, responsible for access and mobility policy control as well as session management policy control. The PCF can determine at least one intermediate node corresponding to the configuration policy rule, and at least one intermediate node can receive the configuration policy rule.

[0130] If historical policy rules exist in the intermediate node, the historical policy rules are updated by configuring policy rules; if historical policy rules do not exist in the intermediate node, the configured policy rules are stored.

[0131] NEF can specify a Transaction Reference ID in the UDR, and store the Transaction Reference ID and the requested service operation as a piece of Application Data. The Transaction Reference ID can be an information identifier used to identify and track network transactions.

[0132] NEF can also respond to AF. If the service operation is to create a configuration policy rule, the response information may include the transaction reference ID.

[0133] After the configuration policy rules in the UDR are operated according to the service operation request, the UDR can send the configuration policy rules to the PCF through the Nudr_DM_Notify procedure. The Nudr_DM_Notify procedure can be used to transparently pass on the policies of intermediate nodes.

[0134] The data transmission method provided in this application embodiment can create, update, or delete configuration policy rules for AIoT devices through AF, which can realize flexible updates of configuration policy rules and improve the flexibility of data transmission of AIoT devices. Furthermore, AIoT data with the same data flow information can be clustered into the same target session for transmission through configuration policy rules, which can reduce the load on AIoT devices.

[0135] Figure 7 This is an interactive diagram illustrating a configuration policy rule provided in an embodiment of this application. Please refer to... Figure 7 This can include AF, NEF, UDR, UDM, PCF, and IN. AF can trigger a service operation request, AF can send a service operation request to NEF, and NEF can send a service operation request to the Unified Data Management (UDM). The UDM authorizes and authenticates the service operation request. After successful authorization and authentication, the service operation can be executed in the UDR. NEF can also send a response message back to AF indicating that the UDR has executed the service operation.

[0136] The UDR can send the configuration policy rules corresponding to the service operation request to the PCF. The PCF can identify at least one intermediate node and send the configuration policy rules to each intermediate node. The PCF can also report the sending results of the configuration policy rules to the NEF, and the NEF can report the sending results of the configuration policy rules to the AF.
