[0002] This disclosure is based on and claims the priority of the Chinese patent application with application number 202410333997.6 and application date March 22, 2024. The entire content of the Chinese patent application is hereby incorporated into this application by reference. Technical Field

[0003] The present disclosure relates to the field of wireless communication technologies, and in particular to a passive service processing method, apparatus, device, medium, and program product. Background Art

[0004] The network architecture of the 5G system includes terminal equipment, access network (AN) equipment, core network elements, and data network (DN). Passive services will have different expectations and requirements for the services that the cellular network can provide, depending on their business needs and business models. For example, some passive services require the network to authenticate and manage passive devices, and the network needs to provide additional security encryption protection for tag services; some passive services do not have high security and confidentiality requirements or their security and confidentiality are mainly isolated through physical space, which requires the network to simplify the tag authentication process as much as possible. The diversity of tags, different business needs, and the upgrade status of existing networks also require more flexible solutions for the cellular passive infrastructure and the device registration management and service transmission processes based on the network architecture.

[0005] However, the existing technology has at least the following problems: In the existing technology, in the process of processing the registration authentication and verification process of passive devices in the cellular network, most business processes need to initiate a signaling connection or a session connection, and perform business transmission based on the session connection.

[0075] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0077] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0078] Referring to Figure 1, it is a schematic diagram of the structure of a cellular passive architecture in the prior art. The existing 5G system network architecture includes terminal devices, access network equipment (R)AN, core network elements, and data network DN, among others. The core network may include, but is not limited to, the following network elements: access and mobility management function (AMF), authentication server function (AUSF), unified data management (UDM), session management function (SMF), user plane function (UPF), policy control function (PCF), network exposure function (NEF), and network repository function (NRF). Among them, the AMF network element is the termination point of non-access stratum (NAS) signaling and is mainly responsible for user access authentication and mobility management. The terminal device and the AMF can communicate through N1NAS messages. The communication messages between the terminal device and the AMF can also be transferred through RAN N2 messages. The RAN and the AMF communicate through N2 messages. The AUSF network element has an authentication service function and is used to process authentication requests for 3rd Generation Partnership Project (3GPP) access and non-3Gpp access. The UDM network element is used to manage user contract information and complete user authentication and authorization. The SMF network element is responsible for session management, such as user session establishment and deletion, maintenance of protocol data unit (PDU) session context and user plane forwarding pipeline information, etc. The UPF network element is used to process user messages, such as forwarding and billing. The NEF network element can be used to perform protocol conversion for external and internal interactions. In the cellular passive architecture, it also includes passive tags and passive IoT servers (servers). The passive IoT server can trigger the excitation source through the 5G network architecture to send passive instructions to the passive tags and realize the management of passive service data. It should be noted that passive tags are diverse and the passive service requirements are different. In order to meet all requirements, the existing passive service processing process is relatively complicated.

[0079] To solve the above problems, see Figure 2, which is a schematic diagram of the structure of the cellular passive architecture provided by the embodiment of the present disclosure. In the embodiment of the present disclosure, a system architecture that integrates passive Internet of Things technology with a cellular system is proposed. In the cellular passive architecture of the embodiment of the present disclosure, a new cellular passive management function gateway is added to manage the device and service of passive devices. Device management includes device registration, authentication, passive device capability activation and management, etc., and service management includes passive service access permission management, passive service command processing, and active periodic inventory. At the same time, new interfaces are added to this architecture:

[0080] First data transmission channel Np1: interface between access network equipment RAN and cellular passive management function;

[0081] Second data transmission channel Np2: interface between NEF network element / passive IoT server and cellular passive management function gateway;

[0082] The third data transmission channel Np3: a service-oriented interface presented by the cellular passive management function gateway, such as for interacting with core network elements.

[0083] 3 is a flow chart of a passive service processing method provided by an embodiment of the present disclosure. The present disclosure provides a passive service processing method applied to a cellular passive management function gateway. The method includes steps S11 to S13:

[0084] S11. Determine the passive service processing strategy of the access network device;

[0085] S12. Sending the passive service processing policy to the access network device;

[0086] S13. Receive the passive service data sent by the access network device, and process and transmit the passive service data to the passive Internet of Things server according to the target service processing mode; wherein the target service processing mode is determined by the access network device according to the passive service processing strategy.

[0087] In the embodiment of the present disclosure, the access network device RAN functions as a reader / writer to obtain the passive service data of the passive tag, and the passive service data includes relevant service data of the passive tag registration, passive tag inventory and / or passive tag status update. During the transmission of the passive service data, the network establishes a first data transmission channel NP1 and a second data transmission channel NP2 according to the supported service type of the access network device (reader / writer). After receiving the passive service processing strategy determined by the cellular passive management function gateway, the access network device determines the corresponding target service processing mode according to the service type or service demand of the passive service data of the passive tag and the passive service processing strategy, and transmits it to the cellular passive management function gateway. The cellular passive management function gateway processes the passive service data according to the target service processing mode and transmits it to the passive Internet of Things server.

[0088] Preferably, the target service processing mode includes a transparent transmission mode, a semi-transparent transmission mode and a non-transparent transmission mode; wherein, the transparent transmission mode is to transparently transmit the passive service data to the passive Internet of Things server; the semi-transparent transmission mode is to transparently transmit the passive service data to the passive Internet of Things server, maintain the binding information between the passive tag corresponding to the passive service data and the access network device and transmit it to the passive Internet of Things server; the non-transparent transmission mode is to parse and process the passive service data, and transmit the service data generated after processing to the passive Internet of Things server.

[0089] Specifically, the transparent transmission mode of a cellular network means that the cellular network core network does not parse or process passive service data. The cellular passive management function gateway is only responsible for transparently forwarding passive service data between the access network device RAN (passive interrogator) and the passive IoT server. The passive interrogator and the passive IoT server each maintain each other's communication identifiers, such as IP address, port number, MAC address, etc., which are used to initiate a connection between the source interrogator and the passive IoT server.

[0090] The semi-transparent transmission mode of a cellular network means that the cellular core network does not process passive service data, but maintains the binding information between the cellular passive tag and the access network device RAN (reader / writer). The cellular passive management function gateway is responsible for forwarding passive service data between the passive reader / writer and the passive IoT server.

[0091] The non-transparent transmission mode of a cellular network refers to the analysis and processing of passive service data by the cellular network core network, including registration management, authentication and authorization of passive devices, and passive service expansion services. At the same time, it can also provide differentiated transmission services for this type of data, such as faster transmission rates, higher transmission reliability, or more secure transmission channels.

[0092] By adopting the technical means of the embodiments of the present disclosure, it is possible to propose a business interaction process that meets the control requirements of passive services on cellular networks in different scenarios in response to the diversity of passive tags and the different business needs of passive business data, including the network providing different data processing modes for different cellular passive business data, realizing lightweight network deployment, simplifying business processing processes, improving the network's processing rate for different passive services, and expanding the application scenarios of passive services.

[0093] As a preferred implementation, the embodiment of the present disclosure is further implemented on the basis of the above embodiment, step S11, that is, determining the passive service processing strategy of the access network device, includes steps S111 to S115:

[0094] S111. In response to the passive device registration request sent by the access network device, initiate a registration request for the passive device to a preset first core network element;

[0095] S112. Receive a registration response for the passive device returned by the first core network element;

[0096] S113. When the registration response is a successful registration response, initiate a passive service policy request to a preset second core network element;

[0097] S114. Receive a passive service policy response returned by the second core network element; wherein the passive service policy response includes the passive service processing policy;

[0098] S115. Generate a passive device registration response according to the passive service processing policy;

[0099] Then step S12, namely sending the passive service processing policy to the access network device, includes:

[0100] S121. Send the passive device registration response to the access network device.

[0101] In an embodiment of the present disclosure, a passive device registration request is initiated by the access network device, and the passive device is a passive reader / writer. During the registration process of the passive device, the passive service processing strategy is determined so that the target data processing mode for the passive service data can be determined subsequently according to the passive service processing strategy.

[0102] Preferably, the first core network element is a UDM network element, and the second core network element is a PCF network element.

[0103] As a preferred embodiment, the embodiment of the present disclosure is further implemented on the basis of the above embodiment, and the method further includes:

[0104] After receiving the passive service policy response, determining security context information in the process of transmitting passive service data through information interaction of a preset core network element cluster;

[0105] Generating an access network device registration response according to the passive service processing policy includes:

[0106] generating the access network device registration response according to the passive service processing policy and the security context information;

[0107] Then, after receiving the passive service data sent by the access network device, the method further includes:

[0108] The passive service data is securely transmitted to the passive Internet of Things server according to the security context information.

[0109] In the embodiment of the present disclosure, during the registration process of the passive device, the security context information of the passive service data transmission process is also determined simultaneously, including the air interface between the passive tag and the passive reader, the first data transmission channel NP1, the second data transmission channel NP2 and the third data transmission channel NP3, etc., so that the access network equipment and the cellular passive management function gateway can realize the secure transmission of the passive service data according to the security context information. The security context information includes protection algorithm, encryption algorithm and encryption transmission key, etc.

[0110] Preferably, the preset core network element cluster includes several core network elements, such as AMF network elements, UDM network elements and AUSF network elements.

[0111] As a first preferred implementation, see Figure 4, which is a structural diagram of the cellular passive architecture under the first preferred implementation in the embodiment of the present disclosure. In order to determine different data processing modes, the embodiment of the present disclosure sets different channels on the first data transmission channel NP1, namely channel 1, channel 2 and channel 3. Similarly, channels 1, channel 2 and channel 3 are set accordingly on the second data transmission channel NP2, where channel 1 supports transparent transmission mode, channel 2 supports semi-transparent transmission mode, and channel 3 supports non-transparent transmission mode.

[0112] For passive service data acquired through channel 1, the cellular passive management function gateway directly transparently transmits it to the passive IoT server. For passive service data acquired through channel 2, the cellular passive management function gateway maintains basic tag registration information, such as the binding information between the cellular passive tag and the RAN / reader, and sends the data to the passive IoT server without additional processing. For passive service data acquired through channel 3, the cellular passive management function needs to authenticate the data with the core network, obtain service policy information, and negotiate security context information. It can then perform appropriate processing on the data, such as encryption and integrity protection, before sending it to the passive IoT server. NP1 channels can be distinguished by IP address, port number, or tunnel ID. NP1 channel information can be obtained through pre-configuration or real-time configuration by the network when the RAN registers the reader's capability information with the network.

[0113] In an embodiment of the present disclosure, the access network device RAN can send the passive service data to the access network device through the target first data transmission channel corresponding to the target service processing mode after determining the target service processing mode according to the passive service processing strategy; the target first data transmission channel is channel 1, channel 2 or channel 3.

[0114] Then step S13, i.e., receiving the passive service data sent by the access network device, processing the passive service data according to the target service processing mode, and transmitting the passive service data to the passive Internet of Things server, includes:

[0115] Receiving passive service data sent by the access network device through the target first data transmission channel;

[0116] The passive service data is processed according to the target service processing mode, and transmitted to the passive Internet of Things server through the target second data transmission channel corresponding to the target service processing mode; wherein the data transmission mode corresponds to the first data transmission channel and the second data transmission channel.

[0117] In the disclosed embodiments, during network registration of a passive device, such as a tag or reader, the network establishes NP1 and NP2 channels based on the types of services supported by the reader. The reader selects different NP1 channels to transmit passive service data, including passive service commands and / or responses to passive service commands, based on the type or requirements of the tag's passive service data. The cellular passive management function gateway determines the target data processing mode based on the NP1 channel from which the passive service data originates, including cellular network transparent transmission, semi-transparent transmission, and non-transparent transmission.

[0118] 5A-5B , which are flowcharts of a passive service processing method under a first preferred implementation mode in the disclosed embodiment, taking the tag registration process of a passive tag as an example, steps 1 to 19 c are explained.

[0119] Step 1: The access network device (RAN) initiates a tag registration instruction to the passive tag. The RAN can select a specific intermediate device (such as a UE or relay device) within its service range as an activator; or use an activator permanently deployed for tags in this area as an activator for periodic tag management; or the RAN itself can act as an activator, performing both the reader and activator roles. The specific choice of activator is not limited in this disclosure. To ensure the success rate of the inventory, step 1 can be repeated multiple times.

[0120] Step 2: The passive tag sends a tag registration response to the access network device RAN according to the tag registration instruction. The tag response message can carry one or more of the following information: tag identification information (including one or more of the following: temporary identification, permanent identification, global unique identification, etc.), tag type (such as manufacturer, product type, mobility type, etc.), and tag characteristics (such as high mobility, low mobility, fixed).

[0121] Step 3: The access network device RAN initiates a passive device registration request to the cellular passive management function gateway via the first data transmission channel NP1 interface. The passive device registration request carries the reader type, reader ID, reader capability information, tag information, etc. In this step, the passive device registration may include reader registration, activator registration, and tag registration. Reader registration, activator registration, and tag registration can be completed in the same message flow or in different message flows. As shown in Figures 5A-5B, if reader registration and tag registration are completed in the same message flow, steps 4 and 14c, steps 5 and 15c, steps 6 and 16c, and steps 7 and 17c can be combined.

[0122] Step 4: The cellular passive management function gateway sends a registration request message of the passive device to the UDM network element. The message carries one or more of the reader type, reader ID, reader capability information, passive device registration indication information, exciter information, etc.

[0123] Step 5. The UDM network element determines whether the reader and / or exciter can be registered based on the registration request information of the passive device sent by the cellular passive management function gateway. If the UDM authentication fails, a registration rejection response is replied to the cellular passive management function. If the UDM authentication passes, a registration success response is replied to the cellular passive management function.

[0124] Step 6: The cellular passive management function sends the passive service policy request information of the passive device to the PCF gateway. The message carries one or more of the reader type, reader ID, reader capability information, actuator information, and other information.

[0125] Step 7. The gateway PCF determines the passive service processing policy corresponding to the reader ID based on the passive service policy request response information sent by the cellular passive management function gateway, such as whether NP1 interface security key negotiation is required, whether NP1 multi-channel mode is supported, the type of NP1 channel established, and the data processing modes supported by different NP1 channels (including cellular network transparent transmission, semi-transparent transmission, and non-transparent transmission modes).

[0126] Step 8. If the contract data or policy received in step 5 or step 7 indicates that the security context needs to be determined at the air interface between the tag and the reader, or the network NP1 / NP2 / NP3 interface, the cellular passive management function interacts with the core network elements AMF, UDM, and AUSF to determine the integrity protection / encryption algorithm and encryption transmission key for the secure transmission between the air interface (between the tag's RAN reader) and NP1 / NP2 / NP3, as well as other context information.

[0127] Step 9: The cellular passive management function gateway sends a passive device registration response to the access network device RAN, carrying the passive service processing policy, one or more NP1 channel address information, and the security context information obtained in step 8. The NP1 channel address information can be distinguished by IP address, port number, or tunnel ID. The NP1 channel information can be obtained in a pre-configured manner or in real time by the cellular passive management function based on the subscription data or policy received in step 5 or 7.

[0128] It should be noted that the passive tag registration instruction and its response can be initiated before the passive device registration, that is, executed through steps 1 and 2. In addition, the passive tag registration instruction and its response can be initiated after the passive device registration, that is, executed through steps 10 and 11, that is, steps 1 to 2 and steps 10 to 11 can be executed alternatively.

[0129] Step 10: The access network device, RAN, initiates a tag registration instruction to the tag. The RAN can select a specific intermediate device (such as a UE or relay device) within its service range as an activator; or use an activator permanently deployed for tags in this area as an activator for periodic tag management; or the RAN itself can act as an activator, meaning the RAN performs both the reader and activator roles. The specific choice of activator is not limited in this disclosure. Step 10 can be repeated multiple times to ensure the success rate of the inventory.

[0130] Step 11: The passive tag sends a tag registration response to the access network RAN ​​according to the tag registration instruction. The tag response message may carry one or more of the following information: tag identification information (including one or more of the following: temporary identification, permanent identification, global unique identification, etc.), tag type (such as manufacturer, product type, mobility type, etc.), and tag characteristics (such as high mobility, low mobility, fixed).

[0131] Step 12: After receiving the tag registration response, the access network device RAN selects a target first data transmission channel for the transmission of the passive service data, namely, channel 1, channel 2, or channel 3 in the NP1 channel, based on the passive service processing policy information determined in step 9 and in combination with the passive tag type or ID. When the passive service requires the network to use the transparent transmission mode of the cellular network, NP1 channel 1 is used for transmission. The specific data processing flow for the transparent transmission mode service is as follows: 13a-14a; when the passive service requires the network to use the semi-transparent transmission mode of the cellular network, NP1 channel 2 is used for transmission. The specific data processing flow for the semi-transparent transmission mode service is as follows: 13b-16b; when the passive service requires the network to use the non-transparent transmission mode of the cellular network, NP1 channel 3 is used for transmission. The specific data processing flow for the non-transparent transmission mode service is as follows: 13c-19c.

[0132] Transparent mode service:

[0133] Step 13a: The access network device RAN transmits the passive service data obtained in step 2 or step 11 through NP1 channel 1. The message carries the tag ID, reader information, etc.

[0134] Step 14a: Based on the passive service policy, when the cellular passive management function gateway receives passive service data from NP1 channel 1, it determines that this data requires the network to use the transparent transmission mode service of the cellular network. The cellular passive management function gateway then determines that the target second data transmission channel is NP2 channel 1 for data transmission. The cellular passive management function does not parse or process the passive service data received from NP1 channel 1 and is only responsible for transparent forwarding of passive service data between the passive reader and the passive IoT server. The address of the NP2 channel can be pre-configured in the cellular passive management function, and this disclosure does not limit it.

[0135] Semi-transparent transmission mode service:

[0136] Step 13b: The access network device RAN transmits the passive service data obtained in step 2 and / or step 11 through NP1 channel 2. The message carries the tag ID, reader information, etc.

[0137] Step 14b: Based on the passive service policy, when the cellular passive management function gateway receives passive service data from NP1 channel 2, it determines that this data requires the network to use the cellular network semi-transparent transmission mode service. The cellular passive management function gateway then determines that the target second data transmission channel is NP2 channel 2 for data transmission. The cellular passive management function does not process the passive service data, but maintains the binding information between the cellular passive tag and the RAN / interrogator.

[0138] Step 15b: The cellular passive management function gateway transmits the passive service data obtained in step 2 or step 11 via the NP2 channel. The message carries the tag ID, reader information, and a tag registration success indication. The tag registration success indication is used to track the tag's registration in the cellular network to the passive IoT server.

[0139] Step 16b: The passive Internet of Things server determines the information of the tag that has been registered in the cellular network according to the tag registration success indication information.

[0140] Non-transparent mode service:

[0141] Step 13c: The access network device RAN transmits the passive service data obtained in step 2 and / or step 11 through NP1 channel 2. The message carries the tag ID, reader information, etc.

[0142] Step 14c: The cellular passive management function gateway sends a passive tag registration request message to the UDM network element. The message carries one or more of the tag type, tag ID, passive tag registration indication information, reader information, exciter information, and the like.

[0143] Step 15c, the UDM network element determines whether the passive tag can be registered based on the passive tag registration request information sent by the cellular passive management function gateway. If the UDM authentication fails, a registration rejection response is replied to the cellular passive management function. If the UDM authentication passes, a registration success response is replied to the cellular passive management function.

[0144] Step 16c: The cellular passive management function gateway sends a service policy request message for the passive tag to the PCF network element. The message carries one or more of the tag type, tag ID, and other information.

[0145] Step 17c: PCF determines the service policy information corresponding to the tag ID, such as the passive service capability opening policy (e.g., whether to support third-party service query, whitelist / blacklist of third-party service access), based on the passive tag service policy request response information sent by the cellular passive management function.

[0146] In step 18c, the cellular passive management function gateway transmits the passive service data obtained in step 2 or step 11 via NP2 channel 3. The message carries the tag ID, reader information, and a tag registration success indication. The tag registration success indication is used to track the tag's registration in the cellular network to the passive IoT server.

[0147] Step 19c: The passive Internet of Things server determines the information of the tag that has been registered in the cellular network according to the tag registration success indication information.

[0148] Of course, the above-mentioned passive service processing process is also applicable to processes such as inventory counting and status updating of passive tags, which does not affect the beneficial effects achieved by the present disclosure.

[0149] By adopting the technical means of this embodiment, the cellular passive management function gateway determines the passive service processing strategy based on the previously configured strategy or the service strategy obtained from other network elements of the core network, as well as the message type of the passive data, the passive tag ID, the passive data type identifier / passive data processing mode identifier, etc. When registering the reader capability information with the cellular network, the RAN performs NP1 multi-channel configuration, including that the NP1 channel can be distinguished by IP address, port number, or by tunnel ID. After the RAN receives the tag registration / inventory / status update response of the tag, it selects the NP1 transmission channel for the passive service information transmission according to the passive service processing strategy information. The cellular passive management function gateway determines the target data processing mode that the network needs to use for this data based on different NP1 channels, including transparent transmission mode service, semi-transparent transmission mode service, and non-transparent transmission mode service. The disclosed embodiment can simplify the implementation complexity of the cellular passive management function and improve the processing rate of various passive services of the network.

[0150] As a second preferred implementation, see Figure 6, which is a structural diagram of the cellular passive architecture under the second preferred implementation in the embodiment of the present disclosure. In the embodiment of the present disclosure, the first data transmission channel NP1 is not divided into channel 1, channel 2 and channel 3, and channels 1, channel 2 and channel 3 are correspondingly set on the second data transmission channel NP2, where channel 1 supports transparent transmission mode, channel 2 supports semi-transparent transmission mode, and channel 3 supports non-transparent transmission mode. In order to determine different data processing modes, type identification information of passive service data is defined.

[0151] In an embodiment of the present disclosure, the access network device can add passive data type identification information to the passive service data according to the target transmission mode after determining the target service processing mode according to the passive service processing strategy;

[0152] Then step S13, i.e., receiving the passive service data sent by the access network device, processing the passive service data according to the target service processing mode, and transmitting the passive service data to the passive Internet of Things server, includes:

[0153] Receiving passive service data sent by the access network device;

[0154] determining the target service processing mode according to the passive data type identification information in the passive service data;

[0155] The passive service data is processed according to the target service processing mode, and transmitted to the passive Internet of Things server through the target second data transmission channel corresponding to the target service processing mode; wherein there is a corresponding relationship between the data transmission mode and the second data transmission channel.

[0156] In the disclosed embodiments, during network registration of a passive device, such as a tag or reader, the network establishes NP1 and NP2 channels based on the types of services supported by the reader. Based on the tag's passive service data type or requirements, the reader adds corresponding passive data type identification information to the passive service data, indicating the target data processing mode required for the passive service data. After receiving the passive service data via the NP1 channel, the cellular passive management function gateway determines the target data processing mode based on the passive data type identification information, including cellular network transparent transmission, semi-transparent transmission, and non-transparent transmission modes.

[0157] Preferably, the access network device is capable of adding passive data type identification information to the passive service data according to the target transmission mode, and the specific steps include:

[0158] Determining a communication protocol with the cellular passive management function gateway;

[0159] Determining the passive data type identification information according to the target transmission mode;

[0160] The passive data type identification information is added to the communication protocol packet header of the passive service data.

[0161] Optionally, the communication protocol includes IP protocol or GTP protocol, namely GPRS tunneling protocol (GPRS Tunneling Protocol). Of course, other types of communication protocols may also be included.

[0162] 7 , which is a flowchart of a passive service processing method according to a second preferred implementation mode of the present disclosure, still taking the tag registration process of a passive tag as an example, including steps 1 to 21 for explanation.

[0163] Step 1: The access network device (RAN) initiates a tag registration instruction to the passive tag. The RAN can select a specific intermediate device (such as a UE or relay device) within its service range as an activator; or use an activator permanently deployed for tags in this area as an activator for periodic tag management; or the RAN itself can act as an activator, performing both the reader and activator roles. The specific choice of activator is not limited in this disclosure. To ensure the success rate of the inventory, step 1 can be repeated multiple times.

[0164] Step 2: The passive tag sends a tag registration response to the access network device RAN according to the tag registration instruction. The tag response message can carry one or more of the following information: tag identification information (including one or more of the following: temporary identification, permanent identification, global unique identification, etc.), tag type (such as manufacturer, product type, mobility type, etc.), and tag characteristics (such as high mobility, low mobility, fixed).

[0165] Step 3: The access network device RAN initiates a passive device registration request to the cellular passive management function gateway via the first data transmission channel NP1 interface. The passive device registration request carries the reader type, reader ID, reader capability information, tag information, etc. In this step, the passive device registration may include reader registration, activator registration, and tag registration. Reader registration, activator registration, and tag registration can be completed in the same message flow or in different message flows. As shown in Figures 5A-5B, if reader registration and tag registration are completed in the same message flow, steps 4 and 14c, steps 5 and 15c, steps 6 and 16c, and steps 7 and 17c can be combined.

[0166] Step 4: The cellular passive management function gateway sends a registration request message of the passive device to the UDM network element. The message carries one or more of the reader type, reader ID, reader capability information, passive device registration indication information, exciter information, etc.

[0167] Step 5. The UDM network element determines whether the reader and / or exciter can be registered based on the registration request information of the passive device sent by the cellular passive management function gateway. If the UDM authentication fails, a registration rejection response is replied to the cellular passive management function. If the UDM authentication passes, a registration success response is replied to the cellular passive management function.

[0168] Step 6: The cellular passive management function sends the passive service policy request information of the passive device to the PCF gateway. The message carries one or more of the reader type, reader ID, reader capability information, actuator information, and other information.

[0169] Step 7. The gateway PCF determines the passive service processing policy corresponding to the reader ID based on the passive service policy request response information sent by the cellular passive management function gateway, such as whether NP1 interface security key negotiation is required, whether NP1 multi-channel mode is supported, the type of NP1 channel established, and the data processing modes supported by different NP1 channels (including cellular network transparent transmission, semi-transparent transmission, and non-transparent transmission modes).

[0170] Step 8. If the contract data or policy received in step 5 or step 7 indicates that the security context needs to be determined at the air interface between the tag and the reader, or the network NP1 / NP2 / NP3 interface, the cellular passive management function interacts with the core network elements AMF, UDM, and AUSF to determine the integrity protection / encryption algorithm and encryption transmission key for the secure transmission between the air interface (between the tag's RAN reader) and NP1 / NP2 / NP3, as well as other context information.

[0171] Step 9: The cellular passive management function gateway sends a passive device registration response to the access network device RAN, carrying the passive service processing policy, one or more NP1 channel address information, and the security context information obtained in step 8. The NP1 channel address information can be distinguished by IP address, port number, or tunnel ID. The NP1 channel information can be obtained in a pre-configured manner or in real time by the cellular passive management function based on the subscription data or policy received in step 5 or 7.

[0172] It should be noted that the passive tag registration instruction and its response can be initiated before the passive device registration, that is, executed through steps 1 and 2. In addition, the passive tag registration instruction and its response can be initiated after the passive device registration, that is, executed through steps 10 and 11, that is, steps 1 to 2 and steps 10 to 11 can be executed alternatively.

[0173] Step 10: The access network device, RAN, initiates a tag registration instruction to the tag. The RAN can select a specific intermediate device (such as a UE or relay device) within its service range as an activator; or use an activator permanently deployed for tags in this area as an activator for periodic tag management; or the RAN itself can act as an activator, meaning the RAN performs both the reader and activator roles. The specific choice of activator is not limited in this disclosure. Step 10 can be repeated multiple times to ensure the success rate of the inventory.

[0174] Step 11: The passive tag sends a tag registration response to the access network RAN ​​according to the tag registration instruction. The tag response message may carry one or more of the following information: tag identification information (including one or more of the following: temporary identification, permanent identification, global unique identification, etc.), tag type (such as manufacturer, product type, mobility type, etc.), and tag characteristics (such as high mobility, low mobility, fixed).

[0175] Step 12: After receiving the tag registration response from the passive tag, the access network device RAN determines the passive data type identification information of the passive service data transmitted on NP1 based on the passive service processing policy information determined in step 9. The access network device RAN adds the passive data type identification information to the passive service data.

[0176] Optionally, an example of a method for the access network device RAN to add the passive data type identification information to the passive service data is as follows:

[0177] Method 1:

[0178] Taking the GTP protocol as an example in the NP1 interface, the access network device RAN carries the passive data type identification information in the GTP protocol packet header of the data packet in step 13 sent to the cellular passive management function gateway. The implementation process is as follows:

[0179] Required fields:

[0180] Version number (Ver): used to identify the version of the GTP protocol, converted into decimal representation.

[0181] Protocol Type (PT): used to distinguish between GTP (set to '1') and GTP' (set to '0') protocols.

[0182] Extension header flag (e): Set to '1' to indicate that there is a next extension header field. Set to '0' to indicate that there is no next extension header field, or that there is one but no interpretation is required.

[0183] Sequence Number Flag (s): Set to '1' to indicate the presence of a sequence number field. Set to '0' to indicate either the absence of a sequence number field or the presence of a sequence number field but no interpretation is required. The s flag shall be set to '1' in GTP-C messages.

[0184] N-PDU Number Flag (Pn): Set to '1' to indicate the presence of an N-PDU Number field. Set to '0' to indicate either the absence of an N-PDU Number field or its presence but no interpretation is required. This flag is only meaningful for GTP-U (GPRS Tunnelling Protocol for User Plane). Therefore, GTP-C (GPRS Tunnelling Protocol for Control Plane) does not use this flag.

[0185] Message Type: This field indicates the type of GTP message.

[0186] Length: This field indicates the payload length in bytes, that is, the length of the remaining portion of the packet excluding the mandatory part of the GTP header (i.e., excluding the first 8 bytes).

[0187] Tunnel Endpoint Identifier (TEID): This field clearly identifies the tunnel endpoint in the GTP-U or GTP-C protocol entity at the other end.

[0188] Optional fields:

[0189] Sequence Number: This field is optional in GTP-U. For GTP-C control plane messages, the sequence number is used to identify the transaction. When transporting over a GTP-U tunnel, if transmission order must be preserved, this field is used to number the T-PDUs, and the sequence number is incremented for each transmitted T-PDU.

[0190] N-PDU Number: This field is used during routing area updates between Serving GPRS Support Nodes (SGSNs) and certain inter-system handovers (such as handovers between 2G and 3G radio access networks). When the MS and SGSN communicate in confirmed mode, this field is used to coordinate data transmission between them. The exact meaning of this field depends on the use case. For example, from GSM / GPRS to GSM / GPRS, this field is the SNDCP N-PDU number.

[0191] Next Extension Header Type: This field defines the type of the extension header that follows this field in the G-PDU (GPRS Tunnelling Protocol Packet Data Unit).

[0192] In the disclosed embodiment, a message type is added to the "Message Type" field or "Next Extension Header Type" field of the GTP protocol to indicate the passive data type identifier. This indicates the data processing mode of the cellular passive management function gateway after receiving this message, such as transparent transmission mode service, semi-transparent transmission mode service, or non-transparent transmission mode service. The cellular passive management function tunnel identifier can be pre-configured in the RAN or sent to the RAN by other core network elements such as the AMF, SMF, PCF, and UDM during steps 3 to 9.

[0193] Method 2:

[0194] Taking the IP protocol as an example in the NP1 interface, the access network RAN ​​carries the passive data type identification information in the IP protocol packet header of the data packet in step 13 sent to the cellular passive management function gateway. The implementation process is as follows:

[0195] In the IP message header field, such as the passive data type identification information of the passive data carried by this IP data packet in the option field, it is used to indicate the data processing mode of the cellular passive management function after receiving this message, such as transparent transmission mode service, semi-transparent transmission mode service or non-transparent transmission mode service.

[0196] Step 13: The access network RAN ​​transmits the passive service data obtained in step 2 or step 11 through the NP1 channel. The message carries the tag ID, reader information, passive data type identification information, etc.

[0197] Step 14: The cellular passive management gateway determines the target data processing mode based on the previously configured policy or the passive service processing policy obtained from other network elements in the core network in step 5 / step 7, as well as the message type, passive tag ID, and passive data type identification information of the passive data in step 12.

[0198] When it is determined that this data requires the cellular network's transparent transmission mode service, the cellular passive management function gateway determines that the target second data transmission channel is NP2 channel 1. The cellular passive management function does not parse or process the passive service data obtained from NP1, indicating that the passive data type identification information indicates support for transparent transmission mode services. It only provides transparent forwarding of the passive service data between the passive reader and the passive IoT server. In other words, step 20 is directly executed. The cellular passive management function transmits the passive service data obtained in step 2 or step 11 via NP2 channel 1, carrying the tag ID and reader information.

[0199] When the network determines that this data requires the use of the cellular network's semi-transparent transmission mode, the cellular passive management function gateway determines the target second data transmission channel as NP2 channel 2 for data transmission. The cellular passive management function gateway does not process the passive service data, but maintains the binding information between the cellular passive tag and the RAN / reader. Therefore, steps 19-21 are executed.

[0200] When it is determined that this data requires the use of the cellular network's non-transparent transmission mode, the cellular passive management function gateway determines that the target second data transmission channel is NP2 channel 3 for data transmission. The cellular passive management function gateway must complete the registration of the tag device information with other network elements in the cellular core network, such as the AMF and UDM. After that, the passive data is transmitted via NP2 channel 3. Steps 15-21 are executed.

[0201] Step 15: The cellular passive management function gateway sends a passive tag registration request message to the UDM network element. The message carries one or more of the tag type, tag ID, passive tag registration indication information, reader information, exciter information, and the like.

[0202] Step 16: The UDM network element determines whether the passive tag can be registered based on the passive tag registration request information sent by the cellular passive management function gateway. If the UDM authentication fails, a registration rejection response is sent to the cellular passive management function. If the UDM authentication passes, a registration success response is sent to the cellular passive management function.

[0203] Step 17: The cellular passive management function gateway sends service policy request information of the passive tag to the PCF network element. The message carries one or more of the tag type, tag ID and other information.

[0204] Step 18: The PCF network element determines the service policy information corresponding to the tag ID, such as the passive service capability opening policy (e.g., whether to support third-party service query, whitelist / blacklist of third-party service access), based on the passive tag service policy request response information sent by the cellular passive management function.

[0205] Step 19: The cellular passive management function does not process the passive service data, but maintains the binding information between the cellular passive tag and the RAN / reader. The cellular passive management function gateway transmits the passive service data obtained in step 2 or step 11 through NP2 channel 2.

[0206] Step 20: The cellular passive management function gateway transmits the passive service data obtained in step 2 or step 11 via NP2 channel 3. The message carries the tag ID, reader information, and a tag registration success indication. The tag registration success indication is used to track the tag registration in the cellular network to the passive IoT server.

[0207] Step 21: The passive Internet of Things server determines the information of the tag that has been registered in the cellular network according to the tag registration success indication information.

[0208] By adopting the technical means of this embodiment, the cellular passive management determines the passive service processing strategy based on the previously configured strategy or the service strategy obtained from other network elements of the core network, as well as the message type of the passive data, the passive tag ID, the passive data type identifier / passive data processing mode identifier, etc. After the RAN receives the tag registration / inventory / status update response, it determines the passive data type identifier information transmitted on NP1 based on the passive service processing strategy information. The RAN carries the passive data type identifier information in the passive service data packet sent to the cellular passive management function. The cellular passive management function determines the target data processing mode that the network needs to use for this data based on the passive data type identifier information obtained from NP1, including transparent transmission mode service, semi-transparent transmission mode service, and non-transparent transmission mode service. Compared with the first preferred embodiment, the embodiment of the present disclosure can simplify the management and maintenance complexity of the interface channel between the RAN and the cellular passive management function.

[0220] Preferably, the adding of passive data type identification information to the passive service data according to the target transmission mode includes:
