For example, in a city, network operators can deploy passive Internet of Things functional network elements for logistics services in logistics centers and logistics parks, etc., deploy passive Internet of Things functional network elements for agricultural services in agricultural clusters on the edge of the city, such as large farms, and deploy passive Internet of Things functional network elements for commercial services and family services in cities, commercial areas and residential areas. Finally, all distributed passive Internet of Things functional network elements in the entire city can be combined to form a relatively large-scale passive Internet of Things network to realize the processing of data from each passive Internet of Things device.

[0169] like Figure 1As shown, Figure 1 A schematic diagram of an application scenario of a data transmission method provided in an embodiment of the present application. The application scenario includes an application function network element 100, a network open function network element 200, a network storage function network element 300, a passive Internet of Things network element 400, an access network device 500, and a passive Internet of Things terminal 600. Among them, the network storage function network element 300 stores the corresponding relationship between the passive Internet of Things function network element 400 and the passive Internet of Things terminal 600, and the network open function network element 200 is connected in communication with the network storage function network element 300 to perform relationship query, etc. The passive Internet of Things network element 400 is connected in communication with the access network device 500 and the network open function network element 200 to perform service handling functions such as activation or deregistration of the passive Internet of Things terminal 600.

[0170] Among them, the application function (AF) network element 100 refers to various services of the application layer. The AF network element in the embodiment of the present application can be a third-party AF (such as a video server, a game server). Since the third-party AF is not in the trusted domain, it is necessary to access other network function (NF) network elements through the network exposure function (NEF) network element 200.

[0171] The network open function element 200 is located in the core network of the fifth generation mobile communication technology network (5G) and the internal AF, and is responsible for managing all external applications that open network data to the outside world. In actual communication, if you need to access the internal data of the 5G core network, you need to go through the NEF element 200. The NEF element 200 provides corresponding security guarantees to ensure the security of external applications to the 3gpp network, and provides functions such as external application QoS customization capability opening, mobility status event subscription, and AF request distribution.

[0172] The NF Repository Function (NRF) network element 300 is used to register, manage, and detect the status of NF network elements, realize mutual discovery of NF network elements, and communicate through the Application Program Interface (API).

[0173] The passive Internet of Things network element 400 has data storage and data processing functions. The passive Internet of Things network element 400 in the embodiment of the present application stores the base station identifier of the access network device 500, the device identifier of the passive Internet of Things terminal 600, and the storage data of each passive Internet of Things terminal 600.

[0174] The access network device 500 can be a base station (Base Transceiver Station, BTS) in Global System of Mobilecommunication (GSM) or Code Division Multiple Access (CDMA), or a base station (NodeB, NB) in Wideband Code Division Multiple Access (WCDMA), or an evolved base station (Evolutional Node B, eNB or eNodeB) in LTE, or a relay station or access point, or a base station in a 5G network, etc., and is not limited here.

[0175] Ambient IoT terminal 600 refers to a terminal device with no battery design, which obtains energy based on the environment, has ultra-low power consumption and does not carry a SIM card, such as wind power generation equipment, hydropower generation equipment, Radio Frequency Identification (RFID) equipment, etc. Ambient IoT terminal 600 has the characteristics of wide application range, low mobility, large number of terminals, large number of connections, and small amount of transmitted data. Its distribution shows the characteristics of small outdoor terminal density and sparse distribution, and large indoor terminal density and concentrated distribution according to the usage scenario definition (TR 22.840) of the 3rd Generation Partnership Project (3GPP) in SA1.

[0176] In addition, since passive IoT terminals cannot be equipped with Subscriber Identity Module (SIM) cards, passive IoT terminal devices directly access the core network through the interface on the access network device side. At the same time, the large number of passive IoT terminals and the small amount of data will also have a huge impact on their access to the 5G core network. Therefore, how to effectively provide fast and easy network access for a large number of passive IoT terminals, and collect, aggregate, and process a large number of small data packets is one of the key issues that need to be addressed in the process of providing network access for passive IoT terminals.

[0177] Related technologies, when passive IoT terminal devices are connected to the core network, they are usually deployed in a centralized manner, by storing all the information of passive IoT terminals connected to the network in a single passive IoT network element, resulting in the application side having to query all the terminals connected to the network through this network element when querying the information corresponding to a certain terminal or a group of terminals. Because the number of passive IoT terminals is huge, each query and data transmission will generate a lot of consumption. In addition, a large amount of data storage, transmission, processing and query also place high demands on the computing power, data transmission capability, data storage capacity and other related aspects of this centrally deployed network element.

[0178] Based on this, an embodiment of the present application provides a method for distributed deployment of passive Internet of Things network elements. By deploying corresponding passive Internet of Things network elements for network elements of different base stations, while connecting the passive Internet of Things terminals to the core network, the cost of deployment and operation of the network elements is effectively reduced, thereby providing efficient services for passive Internet of Things terminals.

[0179] Moreover, each passive IoT network element is independent of each other, which can not only effectively avoid the compatibility risk caused by enhancing different passive IoT network elements, but also effectively reduce the actual deployment cost and the security risk of the network being attacked due to the access of low-privilege passive IoT terminals. At the same time, it avoids conflicts between passive IoT terminals and other traditional 3GPP terminals, and realizes a kind of "isolation" in terms of business and security.

[0180] Specifically, according to the number of passive IoT terminals loaded by the base station, the location of the base station, and the application scenario, single base station deployment, multiple base station deployment, or hybrid deployment can be performed. The following describes different deployment methods:

[0181] (1) Single base station deployment: A passive IoT functional network element is connected to a single base station.

[0182] (2) Multi-base station deployment: One passive IoT network element provides services for multiple base stations, and multiple base stations provide services for passive IoT terminals.

[0183] (3) Hybrid deployment: A passive IoT terminal provides services to multiple base stations, and the multiple base stations include base stations that do not provide services to passive IoT terminals.

[0184] In combination with the above-mentioned distributed deployment method of IoT network elements, the application scenario of the data transmission method provided in the embodiment of the present application has multiple passive IoT network elements, and each passive IoT network element is connected to a passive IoT terminal through a different base station.

[0185] Figure 2 A typical system diagram of a data transmission scenario, including multiple passive IoT network elements, Figure 2Take three passive IoT network elements as an example. Different passive IoT network elements are connected to different base stations and provide services for multiple passive IoT terminals within the range of the base stations. Figure 2 The passive IoT network element 01 in the system provides services for the passive IoT terminals of a single base station. Figure 2 The passive IoT network element 02 in the system provides services for the passive IoT terminals of all base stations and for the base stations. Figure 2 The passive Internet of Things network element 03 provides services for the passive Internet of Things terminals of some base stations, and some base stations corresponding to the passive Internet of Things network element 03 can also provide services for the active Internet of Things terminal 700 defined by 3GPP. The active Internet of Things terminal 700 can directly access the access and mobility management network element (Access and Mobility Management Function, AMF) in the core network through the base station, and transmit data with the network open function network element and application function network element in the core network.

[0186] It should be noted that the beneficial effects brought about by the embodiments of the present application or the technical problems solved are not limited to this one, but may also include other implicit or related problems. For details, please refer to the description of the following embodiments.

[0187] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0188] In one embodiment, Figure 3 As shown, a data transmission method is provided, which is applied to any passive Internet of Things network element distributedly deployed in a core network, and each passive Internet of Things network element in the core network is connected to a passive Internet of Things terminal through different base stations. The method includes the following steps:

[0189] S301, receiving a service data acquisition request of a target passive Internet of Things terminal sent by a network open function network element; the target passive Internet of Things terminal represents at least one passive Internet of Things terminal that accesses the passive Internet of Things network element through a target base station.

[0190] Among them, the passive IoT terminal has a radio frequency coil that can receive the signal from the base station and send and transmit data through the signal. However, since the passive IoT terminal cannot be equipped with a SIM card, the passive IoT terminal cannot directly access the core network through the Radio Access Network (RAN) side and the N2 port.

[0191] Based on this, the embodiment of the present application deploys multiple passive Internet of Things network elements in a distributed manner in the core network, and connects the passive Internet of Things network elements with different base stations and network open function network elements in the core network to establish a transmission channel of "application function network element (core network network element)-network open function network element (core network network element)-passive Internet of Things network element (core network network element)-base station-passive Internet of Things terminal". In this case, the passive Internet of Things terminal can access the core network through the transmission channel, and the core network network element can also query the data of the passive Internet of Things terminal through the transmission channel, thereby completing the data transmission of the passive Internet of Things terminal. In the embodiment of the present application, the base station connected to the target passive Internet of Things terminal is determined as the target base station.

[0192] In addition, considering that passive Internet of Things terminals have the characteristics of wide application range, low mobility, large number of terminals, large number of connections, and small amount of transmitted data, the embodiments of the present application also combine the location of each base station within the coverage area of ​​each passive Internet of Things, the number of passive Internet of Things terminals loaded by each base station, and the application scenarios of each base station when deploying distributed passive Internet of Things network elements, and establish connections between each passive Internet of Things and different base stations in different deployment methods.

[0193] Optionally, each passive IoT network element in the core network is connected to a passive IoT terminal through different base stations, including:

[0194] Each passive Internet of Things network element in the core network is connected to the passive Internet of Things terminal through a single first base station within the coverage area; the first base station represents a base station that provides services for the passive Internet of Things terminal; or,

[0195] Each passive Internet of Things network element in the core network is connected to the passive Internet of Things terminal through all first base stations within the coverage area; or,

[0196] Each passive Internet of Things network element in the core network is connected to the passive Internet of Things terminal through some first base stations and some second base stations within the coverage area; the second base station represents a base station that provides services for the active Internet of Things terminal.

[0197] For example, in sparsely populated areas such as rural areas and nature reserves, the passive IoT network element can be deployed and provide services for a single base station. Alternatively, when a first base station needs to provide services for a large number of passive IoT terminals (such as libraries, logistics distribution centers, hospitals, etc.), the passive IoT network element can also be deployed and provide services for this first base station alone.

[0198] For example, when a large number of passive Internet of Things terminals are dispersedly deployed in a relatively large area and there are multiple first base stations providing services for them at the same time (such as centralized industrial parks, national nature reserves, etc.), passive Internet of Things network elements can be deployed in this area to provide services for all first base stations and passive Internet of Things terminals within the range of each first base station.

[0199] For example, when a large number of passive IoT terminals are deployed in a certain area but other traditional terminals are relatively scattered and there are multiple first base stations and second base stations providing services to different types of users at the same time (such as highway service areas, high-speed railway stations, etc.), passive IoT network elements can be deployed in this area to provide services to all passive IoT terminals within the range of some first base stations and some second base stations.

[0200] In this embodiment, under the deployment conditions of actual base stations and core networks in different scenarios, the distributed deployment of the passive Internet of Things network element is enhanced or weakened in terms of capabilities, and the passive Internet of Things network element can be dynamically and flexibly deployed according to the passive Internet of Things terminal distribution, deployment conditions, corresponding business needs and relevant technical requirements in the actual scenarios.

[0201] Obviously, in the data transmission process in the embodiment of the present application, multiple passive Internet of Things network elements are involved. For any passive Internet of Things network element, the corresponding connected base stations may be one or more; for any base station, multiple passive Internet of Things terminals are usually connected.

[0202] In an embodiment of the present application, the passive Internet of Things network element stores the identifier of the base station connected to the passive Internet of Things, the identifiers of each passive Internet of Things terminal connected to the base station, and the business data stored in each passive Internet of Things terminal.

[0203] Among them, the network storage library functional network element stores the identification of each passive Internet of Things network element and the identification of multiple passive Internet of Things terminals corresponding to each passive Internet of Things network element.

[0204] Taking the application function network element initiating a service data acquisition request for a passive IoT terminal as an example, the data transmission process is explained. Figure 4 , Figure 4 This is a flow chart of the data query steps of the application function network element. Figure 4It can be known that the application function network element queries data through the network open function network element, the passive Internet of Things network element, the base station, and the passive Internet of Things terminal in sequence. Among them, the network open function network element is connected to the network storage library function network element in communication, so that the network open function network element sends a service data acquisition request to the determined passive Internet of Things network element. The interaction process between the network open function network element and the network storage library function network element can be that the network open function network element queries the network storage library function network element, and the network storage library function network element returns the identifier of the passive Internet of Things network element to the network open function network element. Then, the passive Internet of Things terminal returns the service data of the passive Internet of Things terminal to the application function network element through the base station, the passive Internet of Things network element, and the network open function network element in sequence, thereby completing the entire service data acquisition process.

[0205] Optionally, the service data acquisition request carries the identifier and data identifier of the target passive IoT terminal. When the network open function network element receives the service data acquisition request sent by the application function network element, the passive IoT network element that provides connection services for the passive IoT terminal is determined from the network repository function network element according to the identifier of the passive IoT terminal, and the data acquisition request is sent to the designated passive IoT network element.

[0206] Furthermore, when the passive Internet of Things network element receives a service data acquisition request sent by the network open function network element, the passive Internet of Things network element obtains the service data of the target passive Internet of Things terminal according to the service data acquisition request, and returns the acquired service data to the application function network element through the network open network element.

[0207] Since the passive Internet of Things network element stores the identifier of the base station connected to the passive Internet of Things, the identifiers of each passive Internet of Things terminal connected to the base station, and the business data stored in each passive Internet of Things terminal, in this case, the passive Internet of Things network element can use the data identifier in the business acquisition request to query whether all the business data corresponding to the data identifier exists in the current storage. If all the business data corresponding to the data identifier exists in the current storage, the business data is directly extracted from the current storage; if all the business data corresponding to the data identifier does not exist in the current storage, it is broadcast to the target base station corresponding to the target passive Internet of Things terminal, and all the business data corresponding to the data identifier is obtained from the target base station.

[0208] S302, sending the service data of the target passive Internet of Things terminal to the network open function network element.

[0209] When the passive Internet of Things network element obtains the service data of the target passive Internet of Things terminal, the service data is sent to the network open function network element to instruct the network open function network element to send the received service data to the application function network element, thereby completing the data transmission between the application function network element and the target passive Internet of Things terminal.

[0210] In the above data transmission method, the passive Internet of Things network element sends the service data of the target passive Internet of Things terminal to the network open function network element by receiving the service data acquisition request of the target passive Internet of Things terminal sent by the network open function network element. Among them, the target passive Internet of Things terminal represents at least one passive Internet of Things terminal that accesses the passive Internet of Things network element through the target base station. Since the passive Internet of Things network element is in the core network and the passive Internet of Things terminal is connected through the base station, it is equivalent to establishing a data transmission channel including the network open network element, the passive Internet of Things network element, the target base station and the passive Internet of Things terminal through the passive Internet of Things network element. In this case, the passive Internet of Things terminal can access the passive Internet of Things network element through the target base station in the data transmission channel, and then access the core network to realize data transmission of the passive Internet of Things terminal. In addition, passive IoT network elements are distributedly deployed in the core network, and each passive IoT network element in the core network is connected to the passive IoT terminal through different base stations. Since the passive IoT terminals connected to different base stations are different, and different passive IoT network elements are connected to different base stations, the passive IoT terminals served by different passive IoT network elements are different, thereby realizing distributed management of multiple passive IoT terminals of different base stations. This distributed management method of passive IoT terminals can reduce the data storage capacity and operating costs of passive IoT network elements to a certain extent, so that passive IoT network elements can provide efficient services for passive IoT terminals.

[0211] During the data transmission process, the passive Internet of Things network element obtains the service data based on the received service data acquisition request, and sends the service data to the network open function network element. In other words, the passive Internet of Things network element sends the service data to the network open function network element based on the service data acquisition request. Based on this, the following is an example of an achievable way for the passive Internet of Things network element to send service data to the network open function network element based on the service data acquisition request.

[0212] In one embodiment, Figure 5 As shown, the service data acquisition request includes a data identifier, and the service data of the target passive IoT terminal is sent to the network open function network element, including:

[0213] S501, querying the service data of the target passive Internet of Things terminal from the current storage according to the data identifier.

[0214] In the embodiment of the present application, the data currently stored in the passive IoT network element includes: multiple base station identifiers (AP IDs) connected to the passive IoT network element, device identifiers (Ambient IoT IDs) of each passive IoT terminal connected to the base station, and storage data of each passive IoT terminal connected to the base station. Among them, the storage data of each passive IoT terminal includes all business data of the passive IoT terminal, the type identifier of the business data, and the timeliness of the business data.

[0215] The passive IoT network element first extracts the storage data of the target IoT terminal from the current storage according to the ID of the target passive IoT terminal, and then searches for the service data corresponding to the data ID from the storage data of the target IoT terminal according to the data ID in the service data acquisition request. Naturally, the query results can be divided into the following three situations:

[0216] (1) All business data corresponding to the data identifier exists in the current storage.

[0217] (2) There is no business data corresponding to the data identifier in the current storage.

[0218] (3) Some business data corresponding to the data identifier exists in the current storage.

[0219] It should be noted that, considering that the actual transmission of business data involves operations such as data encryption and encoding, all business data corresponding to the data identifier are usually aggregated and sent uniformly to ensure the effectiveness and security of the business data transmission process. In this case, the query results can be divided into the following two situations:

[0220] (1) All business data corresponding to the data identifier exists in the current storage.

[0221] (2) All business data corresponding to the data identifier does not exist in the current storage.

[0222] S502: Send the service data of the target passive Internet of Things terminal to the network open function network element according to the query result.

[0223] Different query results correspond to different business data acquisition methods, and the passive Internet of Things network element sends the acquired business data to the network open function network element.

[0224] Optionally, the passive Internet of Things network element queries the service data of the target passive Internet of Things terminal from the current storage according to the data identifier in the service data acquisition request, and if the current storage includes the service data, sends the service data in the current storage to the passive Internet of Things network element.

[0225] Optionally, the passive Internet of Things network element queries the service data of the target passive Internet of Things terminal from the storage repository according to the data identifier in the service data acquisition request, and if the current storage includes the service data, the service data in the storage repository is sent to the passive Internet of Things network element.

[0226] In the embodiment of the present application, the passive IoT network element queries the service data of the target passive IoT terminal from the current storage according to the data identifier, obtains the service data according to the query result, and sends it to the network open function network element. This is equivalent to the passive IoT network element itself having the service data storage function and the service data processing function, and can quickly obtain the query result according to the currently stored data and data identifier, so as to improve the speed of data query, thereby improving the entire data transmission process.

[0227] The following is an example of an embodiment to illustrate the step of "sending service data to a network open function network element according to the query result" in the above embodiment:

[0228] When the query result indicates that the service data exists in the current storage, the service data is sent to the network open function network element.

[0229] There is business data in the current storage of the passive Internet of Things network element, and the passive Internet of Things network element can send the business data in the current storage to the network open function network element.

[0230] In an embodiment of the present application, when the query result indicates that business data exists in the current storage, the passive Internet of Things network element sends the currently stored business data to the network open function network element, which can increase the speed of returning business data based on the query result, thereby improving the transmission efficiency of the business data.

[0231] Different query results result in different ways of acquiring service data. The above embodiment describes the way of acquiring service data when the query result is that the service data exists in the current storage. Below, as an embodiment parallel to the above embodiment, another achievable step of sending service data to the network open function network element according to the query result is described when the query result is that the service data does not exist in the current storage.

[0232] In one embodiment, Figure 6 As shown, the service data is sent to the network open function network element according to the query result, including:

[0233] S601: When the query result is that there is no service data in the current storage, a data reporting instruction is sent to a target base station.

[0234] The query result is that there is no business data in the current storage, which means that the passive IoT network element does not currently store the business data of the target passive IoT terminal, or the business data currently stored in the passive IoT network element is incomplete. Then, in this case, the passive IoT network element needs to send a data reporting instruction to the target base station connected to the target passive IoT terminal to instruct the target base station to broadcast a data reporting request to all passive IoT terminals corresponding to the target base station.

[0235] S602, receiving reported data from a target base station; the reported data includes service data of a target passive Internet of Things terminal.

[0236] Optionally, the reported data is generated by the target base station according to the identification and business data of the passive Internet of Things terminal reported by multiple passive Internet of Things terminals based on the reported data request broadcast by the target base station.

[0237] In the actual process of signaling interaction, in response to the data reporting request broadcast by the target base station, all passive IoT terminals within the range of the target base station (including the target passive IoT terminal) report the identification and storage data (including all types of business data) of each passive IoT terminal to the target base station, so that the target base station can generate reporting data and feed it back to the passive IoT network element.

[0238] Furthermore, the target base station generates reporting data according to the identifier of the target base station, the identifiers of each received passive Internet of Things terminal and the stored data, and sends the reporting data to the passive Internet of Things network element.

[0239] S603: Send the service data of the target passive Internet of Things terminal to the network open function network element.

[0240] The passive Internet of Things network element determines the service data of the target passive Internet of Things terminal from the storage data of the target passive Internet of Things terminal according to the data identifier in the data acquisition request in the reported data received from the target base station, and sends it to the network open function network element.

[0241] In the embodiment of the present application, when the query result is that there is no business data in the current storage, the passive Internet of Things network element sends a data reporting instruction to the target base station, and obtains the business data of the target passive Internet of Things terminal according to the reported data of the target base station, which can ensure the time consistency of all business data, and then sends the business data to the network open function network element in a unified manner, so that the business data received by the network open function network element is also consistent with the time consistency, so as to improve the effectiveness of the business data. In addition, considering the security of business data transmission, encryption operations may also be involved. The embodiment of the present application sends the business data to the network open function network element at one time, so that the passive Internet of Things network element only needs to perform encryption once, thereby reducing the computing power consumption of the passive Internet of Things network element to a certain extent.

[0242] When the reported data of the target base station is received, it means that there is no service data currently stored in the passive Internet of Things network element. At this time, according to the reported data of the target base station, the passive Internet of Things network element can send the service data in the reported data to the network open function and update the data currently stored in the passive Internet of Things network element. Based on this, the data update process of the passive Internet of Things network element in the data transmission method is described below through an embodiment.

[0243] In one embodiment, the reported data also includes the identifier of the target base station, the identifiers of all passive IoT terminals within the target base station, and service data; the method also includes:

[0244] According to the identification of the target base station, the identifications and business data of all passive IoT terminals within the range of the target base station, the business data of all passive IoT terminals within the range of the target base station currently stored and connected are updated.

[0245] It should be emphasized that the passive Internet of Things network element in the embodiment of the present application has a data storage function, and the data stored in the passive Internet of Things network element includes: the identification of one or more base stations corresponding to the passive Internet of Things network element, the identification and storage data of all passive Internet of Things terminals within the range of each base station.

[0246] Business data refers to part of the data or all of the data in the stored data that corresponds to the data identifier in the business data acquisition request. In other words, if the data identifier corresponds to all data types of the terminal, the business data is the stored data; if the data identifier corresponds to part of the data type of the terminal, the business data is part of the stored data.

[0247] In this embodiment, if the business data of the passive Internet of Things terminal is storage data, the passive Internet of Things updates the business data of each passive Internet of Things currently stored according to the business data.

[0248] If the business data of the passive Internet of Things terminal is partially stored data, the passive Internet of Things will not only update the business data of each passive Internet of Things currently stored according to the business data, but will also update other business data of each passive Internet of Things currently stored according to other business data uploaded by the passive Internet of Things terminal to complete the update of the currently stored data.

[0249] Optionally, the reported data is generated by the target base station according to the identification and business data of the passive Internet of Things terminal reported by multiple passive physical network terminals based on the reported data request broadcast by the target base station.

[0250] That is, the reported data of the target base station includes the identifier of the target base station, the identifiers of all passive IoT terminals within the range of the target base station, and the stored data, wherein the stored data includes the business data.

[0251] In the embodiment of the present application, the service data of the passive IoT terminal within the target base station range currently stored in the passive IoT network element is updated according to the reported data of the target base station, which is equivalent to synchronously updating the correspondence between the target base station identifier and the corresponding passive IoT terminal identifier in the passive IoT network element, and the service data of each passive IoT terminal, thereby improving the validity of the data currently stored in the passive IoT network element. In addition, a passive IoT network element may correspond to one or more target base stations, and for the data reported by each target base station, only the corresponding passive IoT network element needs to be updated once, which reduces the maintenance cost of the distributed passive IoT network element to a certain extent.

[0252] During the data transmission process, the network open function network element determines the passive Internet of Things network element associated with the target passive Internet of Things terminal from the network storage function network element according to the identifier of the target passive Internet of Things terminal, that is, the network storage function network element stores the corresponding relationship between the passive Internet of Things terminal and the passive Internet of Things network element. Then, after the passive Internet of Things network element receives the reported data including the passive Internet of Things terminal, the passive Internet of Things network element can also send the identifier of the passive Internet of Things terminal to the network storage function network element to further update the data currently stored in the network storage function network. Based on this, the steps of updating the network storage function network element data in the data transmission method are described below through an embodiment.

[0253] In one embodiment, the method further comprises:

[0254] The identifications of all passive IoT terminals within the target base station range are sent to the network repository function network element to instruct the network repository function network element to update the stored passive IoT terminals.

[0255] It should be emphasized that the network repository functional network element in the embodiment of the present application has a data storage function, and the data stored in the network repository functional network element includes: the identification of all passive Internet of Things terminals, the identification of all passive Internet of Things network elements, and the correspondence between each passive Internet of Things terminal and the passive Internet of Things network element.

[0256] The passive Internet of Things network element sends the identifiers of all passive Internet of Things terminals within the target base station range to the network repository functional network element to instruct the network repository functional network element to update the corresponding relationship between the currently stored passive Internet of Things terminals and passive Internet of Things network elements.

[0257] In an embodiment of the present application, by sending the identifiers of all passive Internet of Things terminals under the target base station to the network repository functional network element, the correspondence between the passive Internet of Things network elements and the passive Internet of Things terminals is updated, thereby improving the validity of the data currently stored in the network repository functional network element.

[0258] It should be noted that during the entire data transmission process, in order to ensure the validity of the data currently stored in the passive Internet of Things network element and the data stored in the network storage repository functional network element as much as possible, the passive Internet of Things network element can periodically collect the storage data of the passive Internet of Things terminals of all base stations corresponding to the passive Internet of Things network element, and regularly update the data currently stored in the passive Internet of Things network element and the data currently stored in the network storage repository functional network element.

[0259] Based on this, the following describes an embodiment of the periodic update procedure of data of a passive IoT network element during data transmission.

[0260] In one embodiment, Figure 7 As shown, the method also includes:

[0261] S701, sending a data reporting instruction of a passive Internet of Things terminal to all base stations connected to the passive Internet of Things network element according to a preset period.

[0262] The passive Internet of Things network element sends a data reporting instruction to all base stations connected to the passive Internet of Things network element to instruct each base station to broadcast a reporting data request to all passive Internet of Things terminals corresponding to each base station.

[0263] In response to the data reporting request broadcast by each base station, all passive Internet of Things terminals within the range of each base station report the identification of each passive Internet of Things terminal and all stored business data to the corresponding base station.

[0264] S702: Update the service data of all passive Internet of Things terminals within the range of each base station currently stored according to the base station identifier sent by each base station and the identifiers and service data of all passive Internet of Things terminals within the range of each base station.

[0265] Each base station aggregates its own base station identification, the identifications and service data of all passive IoT terminals received within the range of each base station, generates reporting data of each base station, and sends it to the passive IoT network element.

[0266] The passive IoT network element updates the service data of all passive IoT terminals within the range of each base station currently stored according to the reported data of each base station.

[0267] In the embodiment of the present application, the service data of the passive IoT terminals within the range of each base station currently stored in the passive IoT network element is updated according to the reported data of each base station, which is equivalent to synchronously updating the correspondence between each base station identifier and the corresponding passive IoT terminal identifier in the passive IoT network element, and the service data of each passive IoT terminal, thereby improving the validity of the data currently stored in the passive IoT network element. In addition, a passive IoT network element may correspond to one or more base stations, and for the data reported by each base station, only the corresponding passive IoT network element needs to be updated once, that is, the more base stations the passive IoT network element corresponds to, the more obvious the superiority of the passive IoT network element update method.

[0268] The following describes an embodiment of the data periodic update step of the network storage repository function network element during the data transmission process.

[0269] In one embodiment, the method further comprises:

[0271] The passive Internet of Things network element sends the identifiers of all passive Internet of Things terminals within the range of each base station to the network repository functional network element to instruct the network repository functional network element to update the corresponding relationship between the currently stored passive Internet of Things terminals and passive Internet of Things network elements.

[0272] In an embodiment of the present application, by sending the identifiers of all passive Internet of Things terminals under each base station to the network storage repository functional network element, the correspondence between the passive Internet of Things network elements and the passive Internet of Things terminals is updated, thereby improving the validity of the data currently stored in the network storage repository functional network element.

[0273] The above is a description of the embodiments related to the passive IoT network element as the execution subject. Based on this, the present application embodiment also provides an embodiment corresponding to the above process with the network open function network element as the execution subject.

[0274] Since all the implementation principles and detailed processes of the following embodiments with the network open function network element as the execution subject, as well as the technical effects that can be achieved are the same as those of the above-mentioned embodiments with the passive Internet of Things network element as the execution subject, for the sake of brevity and clarity, the following embodiments will not be described one by one, and the implementation process and implementation effect of each embodiment can be referred to the description of the aforementioned embodiments.

[0275] If Figure 8 As shown, an embodiment of the present application provides a data transmission method, which is applied to a network open function network element, and the method includes:

[0276] S801, sending a service data acquisition request of a target passive IoT terminal to a passive IoT network element; the target passive IoT terminal represents at least one passive IoT terminal connected to the passive IoT network element through a target base station; the passive IoT network element is any passive IoT network element distributedly deployed in a core network, and each passive IoT network element in the core network is connected to the passive IoT terminal through different base stations.

[0277] The network open function network element is connected to multiple distributed passive Internet of Things network elements, and each passive Internet of Things network element is connected to the passive Internet of Things terminals within the range of each base station through different base stations.

[0278] Optionally, each passive Internet of Things network element in the core network is connected to the passive Internet of Things terminal through different base stations, including: each passive Internet of Things network element in the core network is connected to the passive Internet of Things terminal through a single first base station within the coverage area; the first base station represents a base station that provides services for the passive Internet of Things terminal; or, each passive Internet of Things network element in the core network is connected to the passive Internet of Things terminal through all first base stations within the coverage area; or, each passive Internet of Things network element in the core network is connected to the passive Internet of Things terminal through some first base stations and some second base stations within the coverage area; the second base station represents a base station that provides services for the active Internet of Things terminal.

[0279] Before sending a service data acquisition request to the target passive Internet of Things terminal, the network open function network element can determine a passive Internet of Things network element associated with the target passive Internet of Things terminal from multiple passive Internet of Things based on the service data acquisition request, and send the service data acquisition request to the passive Internet of Things network element.

[0280] Optionally, the network open function network element may call the pre-stored correspondence between all passive IoT terminals and passive IoT network elements from a database. In this case, the network open function network element determines to which passive IoT network element to send a service data acquisition request based on the identifier of the target passive IoT terminal.

[0281] S802, receiving service data of a target passive Internet of Things terminal sent by a passive Internet of Things network element.

[0282] The passive Internet of Things network element responds to the service data acquisition request and sends the service data of the target passive Internet of Things terminal to the network open function network element.

[0283] In the embodiment of the present application, the network open function network element sends a service data acquisition request of the target passive Internet of Things terminal to the passive Internet of Things network element, and receives the service data of the target passive Internet of Things terminal sent by the passive Internet of Things network element. Since the passive Internet of Things network element is in the core network and is connected to the passive Internet of Things terminal through the base station, it is equivalent to establishing a data transmission channel including the network open network element, the passive Internet of Things network element, the target base station and the passive Internet of Things terminal through the passive Internet of Things network element. In this case, the passive Internet of Things terminal can access the passive Internet of Things network element through the target base station in the data transmission channel, and then access the core network, so as to realize the data transmission of the passive Internet of Things terminal. In addition, passive IoT network elements are distributedly deployed in the core network, and each passive IoT network element in the core network is connected to the passive IoT terminal through different base stations. Since the passive IoT terminals connected to different base stations are different, and different passive IoT network elements are connected to different base stations, the passive IoT terminals served by different passive IoT network elements are different, thereby realizing distributed management of multiple passive IoT terminals of different base stations. This distributed management method of passive IoT terminals can reduce the data storage capacity and operating costs of passive IoT network elements to a certain extent, so that passive IoT network elements can provide efficient services for passive IoT terminals.

[0284] Below, through an embodiment, the steps of determining the passive Internet of Things network element by the network open function network element during the data transmission process are explained.

[0285] In one embodiment, Fig. 9 As shown, before sending a service data acquisition request of a target passive Internet of Things terminal to a passive Internet of Things network element, the method further includes:

[0286] S901, receiving a data acquisition request sent by an application function network element; the data acquisition request includes a terminal identifier.

[0287] Among them, the data acquisition request includes a terminal identifier and a data identifier. The terminal identifier is used to represent the target passive Internet of Things terminal corresponding to the business data acquisition request, and the data identifier is used to represent the data type information of the target passive Internet of Things terminal that needs to be obtained.

[0288] The service data acquisition request may be triggered by the user in the application function network element based on actual needs, or may be automatically triggered by the application function network element periodically according to a preset time period.

[0289] It should be noted that the terminal identifier and data identifier carried in the data acquisition request and the service data acquisition request in the aforementioned embodiment are the same. The embodiment of the present application takes into account that the initiators of the two requests are different, and the routing information through which the request information passes is also different, which will lead to differences in the packet header information of the request information. Therefore, the request sent by the application function network element is called a data acquisition request, and the request sent by the network open function network element is called a service data acquisition request, for the purpose of distinction.

[0290] S902: Send a network element query request to the network repository function network element according to the terminal identifier.

[0291] The network repository function network element has a data storage function, and the data stored in the network repository function network element includes: the identification of all passive Internet of Things terminals, the identification of all passive Internet of Things network elements, and the corresponding relationship between each passive Internet of Things terminal and the passive Internet of Things network element.

[0292] When receiving a service data acquisition request, the network open function network element carries the terminal identifier in the network element query request and sends the network element query request to the network repository function network element to instruct the network repository function network element to query the passive Internet of Things network element corresponding to the terminal identifier.

[0293] S903: Determine the passive Internet of Things network element according to the passive Internet of Things network element identifier sent by the network storage repository function network element.

[0294] The network storage repository function network element responds to the network element query request and returns the passive Internet of Things network element identifier corresponding to the terminal identifier to the network open function network element.

[0295] The network open function network element determines the passive Internet of Things network element corresponding to the passive Internet of Things network element identifier from multiple passive Internet of Things network elements connected to the network open function network element according to the passive Internet of Things network element identifier sent by the network storage repository function network element.

[0296] In an embodiment of the present application, based on the terminal identifier carried in the service data acquisition request sent by the application function network element, the identifier of the target passive Internet of Things terminal is determined from the network repository function network element, and then the passive Internet of Things network element is determined, which gives full play to the storage function of the network repository function network element and the query function of the network open function, and improves the efficiency of network element query.

Based on this, the embodiment of the present application also provides an embodiment corresponding to the above process with the network storage function network element as the execution subject.

Among them, the target passive Internet of Things terminal represents at least one passive Internet of Things terminal that accesses the passive Internet of Things network element through the target base station. Since the passive Internet of Things network element is in the core network and the passive Internet of Things terminal is connected through the base station, it is equivalent to establishing a data transmission channel including the network open network element, the passive Internet of Things network element, the target base station and the passive Internet of Things terminal through the passive Internet of Things network element. In this case, the passive Internet of Things terminal can access the passive Internet of Things network element through the target base station in the data transmission channel, and then access the core network to realize data transmission of the passive Internet of Things terminal. In addition, passive IoT network elements are distributedly deployed in the core network, and each passive IoT network element in the core network is connected to the passive IoT terminal through different base stations. Since the passive IoT terminals connected to different base stations are different, and different passive IoT network elements are connected to different base stations, the passive IoT terminals served by different passive IoT network elements are different, thereby realizing distributed management of multiple passive IoT terminals of different base stations. This distributed management method of passive IoT terminals can reduce the data storage capacity and operating costs of passive IoT network elements to a certain extent, so that passive IoT network elements can provide efficient services for passive IoT terminals.
