[0116] In the embodiment of the present application, the first policy requesting device is a device capable of managing devices or apparatuses that execute passive services. The label acquisition request is a policy request sent by the first policy requesting device to request a label offload policy for the corresponding passive service.

[0117] Step 102 may be performed before step 101 and may be specifically determined based on actual conditions.

[0118] Step 103: Send a label policy response to the first policy requesting device.

[0119] The label policy response includes a first label diversion policy.

[0120] In other embodiments of the present application, the PCF network element device responds to the label acquisition request sent by the first policy request device, obtains the corresponding first label offload policy, generates a label policy response, and sends the label policy response to the first policy request device. The first label offload policy is the latest label offload policy for the passive service obtained by the PCF network element device.

In this way, after the PCF network element device determines the first label diversion strategy of the passive service, it sends the first label diversion strategy to the AMF network element device and the core network element device, so that different network element devices can manage the passive service, which solves the problem that there is no effective management method for passive service access to the cellular network. It proposes a method for the integrated management of passive services and cellular networks, and realizes the label inventory in the cellular network and the differentiated processing during network transmission according to different passive service requirements.

[0124] Based on the foregoing embodiment, an embodiment of the present application provides a passive service management method. As shown in FIG2 , the method is applied to an AMF network element device. The method includes the following steps:

[0125] Step 201: Send a label acquisition request for requesting to obtain a label diversion policy to a PCF network element device.

[0126] In an embodiment of the present application, after generating a label acquisition request, an access and mobility management function (AMF) network element device sends a label acquisition request to a PCF network element device. The AMF network element device can communicate with passive service-related devices and perform operations such as service management.

[0127] Step 202: Receive a label policy response sent by the PCF network element device.

In this way, after the PCF network element device determines the first label diversion strategy of the passive service, it sends the first label diversion strategy to the AMF network element device. The AMF network element device manages the passive service according to the first label diversion strategy of the receiving end, which solves the problem that there is no effective management method for the current passive service access to the cellular network, and proposes a method for the integrated management of passive services and cellular networks, which realizes the label inventory in the cellular network and the differentiated processing during network transmission according to different passive service requirements.

[0131] An embodiment of the present application provides a passive service management method. As shown in FIG3 , the method is applied to a core network element device having a cellular passive management function, which can serve as middleware between a cellular network and a passive Internet of Things system. The method includes the following steps:

[0133] In the embodiments of the present application, the core network element device with the cellular passive management function mainly corresponds to the cellular passive management function being deployed in the cellular network user plane scenario. In this case, the cellular passive management function can be set on a core network element device such as an NEF network element device and a UPF network element device. When the core network element device with the cellular passive management function generates a label acquisition request, it sends the label acquisition request to the PCF network element device.

[0134] Step 302: Receive a label policy response sent by the PCF network element device in response to the label acquisition request.

[0135] The label policy response includes a first label offload policy for the passive service.

[0136] In an embodiment of the present application, after the core network element device sends a label acquisition request to the PCF network element device, it receives a label policy response sent by the PCF network element device and obtains a first label diversion policy for the passive service corresponding to the label acquisition request.

[0137] Step 303: Based on the first label offload policy, update the label policy corresponding to the passive service to obtain a fifth label offload policy.

[0138] In an embodiment of the present application, after the core network element device determines that it has obtained the latest first label diversion strategy, it updates the locally stored label strategy corresponding to the passive service to obtain an updated fifth label diversion strategy.

In this way, the core network element device receives the first label diversion policy for the passive service sent by the PCF network element device, and realizes the management of the passive service by different network element devices, which solves the problem that there is no effective management method for the current passive service access to the cellular network, and proposes a method for the integrated management of passive services and cellular networks, which realizes the label inventory in the cellular network and the differentiated processing during network transmission according to different passive service requirements.

[0162] In an embodiment of the present application, the PCF network element device determines a second label diversion strategy for the passive service based on the received service configuration parameters for the passive service.

[0163] Step 401c: The PCF network element device updates the label diversion policy corresponding to the passive service based on the second label diversion policy to obtain the first label diversion policy.

[0164] In the embodiment of the present application, the PCF network element device updates the label diversion policy corresponding to the passive service according to the set update rules based on the second label diversion policy corresponding to the service configuration parameters of the newly received passive service, thereby obtaining the final first label diversion policy. At this time, the storage, maintenance and update of the label diversion policy in the PCF network element device are realized.

[0165] Based on the above embodiment, in other embodiments of the present application, step 401 can also be implemented by steps 401d to 401e:

[0166] Step 401d: The PCF network element device receives the third label diversion policy sent by the core network element device.

[0167] Among them, the core network element equipment has the cellular passive management function as the middleware between the cellular network and the passive Internet of Things system.

[0168] In an embodiment of the present application, the process of determining the first label diversion policy by the PCF network element device is implemented when the PCF network element device receives a third label diversion policy for passive services sent by a core network element device having cellular passive management capabilities. The third label diversion policy sent by the core network element device is the latest label diversion policy for passive services determined by the core network element device. The core network element device herein is a network element device of the cellular user plane.

[0169] Step 401e: The PCF network element device updates the label diversion policy corresponding to the passive service based on the third label diversion policy to obtain the first label diversion policy.

[0170] In an embodiment of the present application, after the PCF network element device receives the third label diversion policy sent by the core network element device, it updates the label diversion policy corresponding to the passive service stored in itself using the third label diversion policy to obtain the latest label diversion policy for the passive service.

[0171] Based on the foregoing embodiment, in other embodiments of the present application, the first label diversion strategy at least includes: a diversion filter and a diversion strategy / rule.

[0172] Based on the foregoing embodiments, in other embodiments of the present application, the diversion filter includes at least one or more of the following: tunnel identification information between the passive Internet of Things service node and the network open function network element, tunnel identification information between the passive Internet of Things service node and the cellular passive management function, Internet Protocol address (IP) information of the tag reader, and identity identification information of the tag; the diversion filter includes an uplink filter and a downlink filter; the diversion strategy / rules include the management mode of the cellular network for the passive business equipment, or the diversion mode of the passive business equipment.

[0173] In an embodiment of the present application, the management mode of the cellular network for passive service devices included in the offload policy / rule may include supporting the cellular network to provide device management or passive service management services for passive devices, or not supporting the cellular network to provide device management or passive service management services for passive devices, including passive IoT devices. The offload mode of the passive service device may include not supporting offload between cellular and non-cellular networks, or supporting offload between cellular and non-cellular networks. Passive service devices are passive devices that perform passive services, and may include passive IoT devices.

[0174] Based on the foregoing embodiments, in other embodiments of the present application, when the management mode is the first transmission mode, the cellular network element device only provides network transmission; when the management mode is the second transmission mode, the cellular network element device provides management services for passive Internet of Things devices and passive services.

[0175] In an embodiment of the present application, the first transmission mode is that the cellular network does not support providing device management or passive business management services for passive devices. At this time, the cellular network network element device is used to provide network transmission only for passive devices. The second transmission mode is that the cellular network network element device not only provides network transmission for passive devices, but also provides device management or passive business management services for passive Internet of Things devices.

[0176] Based on the foregoing embodiment, in other embodiments of the present application, as shown in FIG6 , before the AMF network element device executes step 403, it is further configured to execute steps 410 to 412:

[0177] Step 410: The AMF network element device receives the tag registration request message sent by the tag registration activation device.

[0178] The tag registration request message is generated after the tag registration activation device receives the tag activation response / inventory response fed back by the tag.

[0179] In an embodiment of the present application, the tag registration and activation device is a device that can be accessed in a cellular network, can communicate with the tag, and provides registration and activation services for the tag, for example, it can be a terminal device.

[0180] When the tag receives a tag activation instruction / tag inventory instruction sent by the tag registration and activation device, it sends a tag activation response / tag inventory response to the tag registration and activation device according to the tag activation instruction / tag inventory instruction. When the tag receives a tag activation instruction, for example, not an inventory instruction currently in the passive system, during the tag response process, the tag may carry tag identification information in the tag activation response, wherein the tag identification information may include one or more of the following parameters: tag identification, tag type, tag characteristics, etc. The tag identification may, for example, be a tag temporary identification, a tag permanent identification, or a tag globally unique identification, etc. The tag type may, for example, be a manufacturer, a product type, a mobile type, etc. The tag characteristics may, for example, be high mobility, low mobility, fixed, etc. When the tag receives a tag inventory instruction, that is, an inventory instruction currently in the existing passive system, the tag may only carry tag identification information in the tag inventory response, wherein the tag identification information may include one or more of the following: a tag temporary identification, a tag permanent identification, a tag globally unique identification, etc.

[0181] When the tag registration activation device sends a tag registration request message, it can initiate a network registration request for a single tag, or initiate a network registration request for multiple tags. When initiating network registration requests for multiple tags, it can be done in the same registration message or in different registration messages. The tag registration request message can be a non-access stratum (NAS) message sent by the tag registration activation device to the cellular network. In the mobile communication system, it needs to be sent to the AMF network element device through the access network (AN) message of the access network device.

[0182] Step 411: The AMF network element device sends a tag registration request message to the unified data management (UDM) network element device.

[0183] The tag registration request message is used by a Unified Data Management (UDM) network element device to authenticate the passive IoT device corresponding to the tag registration request message.

[0184] In an embodiment of the present application, after the AMF network element device receives the tag registration request message sent by the tag registration activation device, it sends the tag registration request message to the UDM network element device so that the UDM network element device can authenticate the passive IoT device corresponding to the tag registration request message.

[0185] Step 412: The AMF network element device receives the authentication result sent by the UDM network element device.

[0186] In an embodiment of the present application, the UDM network element device performs identity authentication on the passive IoT device corresponding to the tag registration request message, obtains an authentication result, and feeds back the authentication result to the AMF network element device.

[0187] Based on the above embodiment, in other embodiments of the present application, step 403 can be implemented by the following steps:

[0188] Step 403a: If the authentication result is a registration success response message, the AMF network element device sends a label acquisition request to the PCF network element device.

[0189] In an embodiment of the present application, when the UDM network element device performs identity authentication on the passive IoT device corresponding to the tag registration request message and determines that the identity authentication of the passive IoT device is passed, that is, when the authentication result is a passive IoT device registration success response message, the AMF network element device sends a tag acquisition request to the PCF network element device. When the authentication result is a registration failure response message, that is, when the passive IoT device corresponding to the tag registration request message performs identity authentication at the UDM network element device and fails to pass the identity authentication, the UDM network element device replies to the AMF network element device with a registration rejection response, and subsequent operations may not be performed.

[0190] Based on the foregoing embodiment, in other embodiments of the present application, as shown in FIG6 , the AMF network element device is further configured to perform step 413:

[0191] Step 413: The AMF network element device receives the label signing information sent by the UDM network element device.

[0192] Among them, the tag subscription information at least includes the management mode corresponding to the passive Internet of Things device corresponding to the tag registration request message maintained by the UDM network element device.

[0193] In an embodiment of the present application, when the authentication result is a registration success response message, at the same time or after the UDM network element device sends the authentication result of the registration success response message to the AMF network element device, the UDM network element device can also send a label signing message of the management mode corresponding to the passive Internet of Things device corresponding to the label registration request message stored at the UDM network element device, so that the AMF network element device can update the label diversion strategy at the AMF network element according to the label signing information sent by the UDM network element device.

[0194] Based on the foregoing embodiment, in other embodiments of the present application, as shown in FIG6 , after the AMF network element device executes step 412, it is further configured to execute step 414:

[0195] Step 414: If the authentication result is a registration success response message, the AMF network element device sends a tag registration request response message to the tag registration activation device.

[0196] The label registration request response message includes at least the fourth label diversion strategy.

[0197] In an embodiment of the present application, when the UDM network element device performs identity authentication on the passive Internet of Things device corresponding to the tag registration request message and determines that the identity authentication of the passive Internet of Things device is passed, that is, the authentication result is a passive Internet of Things device registration success response message, the AMF network element device receives the authentication result sent by the UDM network element device. After that, the AMF network element device obtains the locally updated tag diversion strategy, that is, the fourth tag diversion strategy, and generates a tag registration request response message to the tag registration activation device according to the fourth tag diversion strategy, so that the tag registration activation device can perform subsequent management of the passive Internet of Things device according to the fourth tag diversion strategy.

[0198] Based on the foregoing embodiment, in other embodiments of the present application, referring to FIG7 , the AMF network element device is further configured to perform steps 415 to 418:

[0199] Step 415: The AMF network element device sends a label registration request to the core network element device.

[0200] Among them, the core network element device has a cellular passive management function as a middleware between the cellular network and the passive Internet of Things system. The tag registration request is used for the passive Internet of Things device to register status information at the core network element device, and carries the fourth tag diversion strategy.

[0201] In an embodiment of the present application, the AMF network element device also generates a label registration request based on the identity identification information of the passive Internet of Things device after identity authentication by the UDM network element device and the fourth label diversion policy updated at the AMF network element device, and sends the label registration request to the core network element device so that the core network element device can register the status of the passive Internet of Things device.

[0202] Step 416: The core network element device receives the label registration request sent by the AMF network element device.

[0203] Among them, the tag registration request is used for the passive Internet of Things device to register status information at the core network element device, and carries the fifth tag diversion strategy.

[0204] Step 417: The core network element device sends a label registration response to the AMF network element device based on the label registration request.

[0205] In an embodiment of the present application, the core network element device receives a label registration request, processes the label registration request, and sends a label registration response to the AMF network element device.

[0206] Step 418: The AMF network element device receives the label registration response sent by the core network element device.

[0207] Among them, the tag registration response is used to indicate that the core network element device has registered the status information of the passive Internet of Things device.

[0208] Based on the foregoing embodiment, in other embodiments of the present application, as shown in FIG8 , the AMF network element device is further configured to perform steps 419 to 420 and / or steps 421 to 422:

[0209] Step 419: The AMF network element device receives a passive Internet of Things instruction sent by the core network element device to instruct a passive Internet of Things operation.

[0210] Among them, the passive Internet of Things instruction is sent by the passive Internet of Things service node to the core network element device, and when the passive Internet of Things service node / core network element device determines that the management mode of the corresponding passive Internet of Things device is the first transmission mode based on the stored label diversion strategy, it is sent to the core network element device.

[0211] In an embodiment of the present application, a passive IoT instruction is an instruction request for a passive IoT service node to perform related operations on a passive service. The passive IoT service node sends the passive IoT instruction to a core network element device. When the passive IoT service node sends the passive IoT instruction to the core network element device, it can distribute and process the instruction according to the label diversion strategy stored at the passive IoT node. When the core network element device receives the passive IoT instruction, it determines the label diversion strategy for the passive service corresponding to the passive IoT instruction stored in the core network element device. When it determines that the management mode of the passive IoT device corresponding to the passive IoT instruction is the first transmission mode, the passive IoT instruction is forwarded to the AMF network element device.

[0212] Step 420: The AMF network element device sends a passive IoT instruction to the radio access network RAN ​​network element device.

[0213] Among them, the AMF network element device sends the passive Internet of Things command to the wireless access network RAN ​​network element device, so that the RAN device sends the passive Internet of Things command to the repeater / reader that communicates with the passive Internet of Things device.

[0214] In an embodiment of the present application, the AMF network element device will send the passive IoT instruction combined with the search to the radio access network (Radio Access Network, RAN) network element device, so that the RAN network element device can send the passive IoT instruction to the repeater / reader currently connected to the RAN network element device, so that the repeater / reader performs the corresponding operation based on the passive IoT instruction.

[0215] Step 421: The AMF network element device determines the target reply content corresponding to the passive IoT command.

[0216] In an embodiment of the present application, the target reply content can be found by the repeater / reader / writer from the content corresponding to the passive service stored in its own storage according to the passive Internet of Things instruction, or it can be obtained from the tag after the repeater / reader / writer sends the passive Internet of Things instruction to the corresponding tag.

[0217] Step 422: The AMF network element device sends the target reply content to the unreachable IoT service node.

[0218] In an embodiment of the present application, the AMF network element device sends the target reply content corresponding to the determined passive Internet of Things instruction to the passive Internet of Things service node, which can be executed according to the corresponding label diversion strategy at the AMF network element device, so that the passive Internet of Things service node can subsequently perform corresponding subsequent analysis and processing on the target reply content according to the corresponding label diversion strategy at the passive Internet of Things service node.

[0219] Based on the foregoing embodiment, in other embodiments of the present application, the AMF network element device is further configured to perform step 423:

[0220] Step 423: When it is determined that the management mode of the passive Internet of Things device indicated in the tag diversion strategy is the first transmission mode, the AMF network element device receives the passive Internet of Things response sent by the user terminal device / repeater / reader.

[0221] Among them, the passive IoT response is the response content sent to the repeater / reader after the corresponding passive IoT device responds to the received passive IoT command.

[0222] In an embodiment of the present application, when the user terminal device / repeater / reader determines that the tag diversion policy indicates that the management mode for the passive IoT device is the first transmission mode, the user terminal device / repeater / reader responds to the received passive IoT instruction, obtains the corresponding passive IoT response, and sends the passive IoT response to the AMF network element device. The process of the user terminal device / repeater / reader responding to the received passive IoT instruction can be: the user terminal device / repeater / reader obtains the corresponding response content from the passive IoT device, i.e., the tag device, or the user terminal device / repeater / reader obtains the corresponding response content from its own storage area.

[0223] Based on the foregoing embodiment, in other embodiments of the present application, referring to FIG. 9 , the core network element device is further configured to perform steps 424 to 426:

[0224] Step 424: The core network element device receives the service configuration parameters of the passive service sent by the passive Internet of Things service node.

[0225] In an embodiment of the present application, when the passive IoT service node is currently able to communicate with the core network element device, the passive IoT service node can directly send service configuration parameters to the core network element device. The core network element device in this process is a cellular network user plane network element device.

[0226] Step 425: The core network element device determines a third label offload strategy for the passive service based on the service configuration parameters.

[0227] In the embodiment of the present application, the core network element device analyzes and processes the received service configuration parameters to generate a third label diversion strategy for the passive service.

[0228] Step 426: The core network element device sends the third label offload policy to the PCF network element device.

[0229] Based on the foregoing embodiment, in other embodiments of the present application, referring to FIG. 10 , the core network element device is further configured to execute steps 427 to 428, or steps 427 and 429:

[0230] Step 427: The core network element device receives the passive Internet of Things instruction sent by the passive Internet of Things service node.

[0231] In an embodiment of the present application, according to the label diversion strategy stored in the core network element device, when it is determined that the core network element device can communicate directly with the passive Internet of Things service node, the passive Internet of Things service node can send the passive Internet of Things instruction directly to the core network element device.

[0232] Step 428: The core network element device determines the pending reply content corresponding to the passive Internet of Things instruction, and sends the pending reply content to the passive Internet of Things service node.

[0233] In an embodiment of the present application, after the core network element device obtains the content to be replied corresponding to the passive IoT command, it sends the content to be replied to the passive IoT service node. The content to be replied can be obtained from a storage area of ​​the core network element device, or the core network element device can obtain the content to be replied from a device such as a tag corresponding to the passive IoT command or a terminal that has the content to be replied.

[0234] Step 429: The core network element device sends a passive IoT instruction to the AMF network element device.

[0235] Among them, the core network element device sends the passive IoT instruction to the AMF network element device according to the instructions in the label diversion strategy, so as to obtain the corresponding reply content from the corresponding passive IoT device.

[0236] In an embodiment of the present application, the core network element device sends the passive Internet of Things instruction to the AMF network element device, so that the corresponding content to be replied can be obtained from the corresponding passive Internet of Things device through the AMF network element device.

[0237] Based on the above embodiment, in other embodiments of the present application, referring to FIG. 10 , after the core network element device executes step 429 , it is further configured to execute steps 430 to 431 :

[0238] Step 430: The core network element device receives the passive IoT response sent by the AMF network element device.

[0239] In an embodiment of the present application, the passive Internet of Things response includes the content to be replied obtained by the AMF network element device.

[0240] Step 431: The core network element device sends a passive Internet of Things response to the passive Internet of Things service node.

[0241] Based on the aforementioned embodiments, the embodiments of the present application provide a system architecture for the integration of passive IoT technology and a cellular system. As shown in FIG11 , the architecture includes: a tag M1, a terminal device user terminal (UE) M2, an access network ((Radio) Access Network, (R) AN) device M3, a core network element M4, and a passive service server M5. The core network elements may include, but are not limited to, the following elements: an access and mobility management function (AMF), an authentication server function (AUSF), a unified data management (UDM), a session management function (SMF), and a user plane function (UPF). The core network elements may also include a network exposure function (NEF), and optionally, a cellular passive management function, which may be implemented using a cellular passive management gateway. Among them, the NEF network element can be used to convert protocols for external and internal interactions, for example, to convert protocols for interactions between external network elements of the 3rd Generation Partnership Project (3GPP) (such as a passive IoT server) and internal network elements of 3GPP (such as SMF). 3GPP networks can refer to networks defined by the 3GPP protocol, such as mobile communication networks, public land mobile networks (PLMNs), non-public networks (NPNs), and other networks that include access networks, core networks, and terminal devices. They can be fifth-generation mobile communication technology (5G) networks or future evolved mobile communication networks. The cellular passive management function can be used to provide middleware functions in the passive IoT system. For example, the passive IoT network element is used to communicate with the passive IoT server and generate operation instructions that can be recognized by the reader or excitation source based on application layer instructions. In Figure 11, interfaces are set up between the AMF network element, SMF network element, UPF network element and the cellular passive management function gateway, indicating that the AMF network element, SMF network element and the cellular passive management gateway can communicate with each other, and the UPF network element and the cellular passive management gateway can also communicate with each other. In the implementation process, the UPF network element and the cellular passive management gateway can communicate using the N6 interface.In addition, it should be noted that in Figure 11, interfaces exist between the terminal device, the (R)AN, and the tag. Specifically, in a system architecture integrating passive IoT technology into a 5G network, the tag can no longer receive downlink passive IoT information via dedicated spectrum, but instead receive it from the terminal device via the cellular air interface. Uplink passive IoT information sent by the tag can be directly sent to the (R)AN via the passive IoT air interface, and the tag can also bypass the terminal device when sending uplink information to the (R)AN. It should also be noted that the cellular passive management gateway in Figure 11 is a separate network element for illustrative purposes only. In other feasible implementations, the cellular passive management gateway can be located in other core network elements, for example, in an NEF network element or in a UPF network element. Assuming the cellular passive management gateway is located in an NEF network element, the system architecture shown in Figure 11 may not include the NEF network element. When two network elements are co-located, the corresponding interactions between the two network elements become internal operations of the co-located network element.

[0242] Based on the system architecture shown in Figure 11, an embodiment of the present application provides a passive service management method, wherein a service diversion diagram of the corresponding passive service diversion strategy protocol can be shown with reference to Figure 12. The passive service management method can be divided into a passive service diversion strategy protocol configuration phase and a passive service diversion strategy execution phase during implementation.

[0243] In the passive service diversion strategy protocol configuration phase, steps a1, b1, and c1 in FIG12 are the passive service server interacting with the internal network elements of the cellular network (such as PCF network element, NEF network element, or UE) to negotiate and determine the label diversion strategy; steps a2, b2, and c2 are the PCF network element sending the label diversion strategy to the UE, AMF network element, and cellular passive management function; steps a3 and b3 are the AMF network element sending the label diversion strategy to the cellular passive management function and UE. It should be noted that the label diversion strategies sent by different network elements can be strategies updated by the sending functional network element based on the received label diversion strategy. In this way, the strategies received by different functional network elements may be the same, partially the same, or completely different, depending on the actual situation.

[0244] During the passive service offload policy protocol configuration phase, the passive service platform interacts with the PCF network element in the cellular network through a capability exposure interface such as the NEF, or directly with the PCF network element in the cellular network through the N5 interface to negotiate the tag offload policy for the passive service. During the cellular network element policy configuration process or during the registration of the passive system device in the cellular network, the PCF network element determines the tag offload policy to the reader / receiver / repeater (which can be a UE or RAN device in the cellular network), the NEF, and the passive service platform. During the tag offload policy configuration phase, the execution nodes that obtain the tag offload policy can be: the UE / reader / repeater, the NEF, and the passive service server.

[0245] Correspondingly, the implementation process of the passive service offload strategy protocol configuration provided in this application corresponds to the service offload schematic diagram corresponding to FIG12 , and specifically includes the following steps:

[0246] Step d11: Determine the label diversion strategy.

[0247] Among them, a process of the PCF network element determining the label diversion strategy can be implemented by the passive Internet of Things server sending the passive service configuration parameters to the PCF network element in step a1 of Figure 12, and the PCF network element determining the label diversion strategy according to the received passive service configuration parameters.

[0248] The passive IoT server, also known as a passive service server or passive service platform, corresponds to the aforementioned passive IoT service node. It interacts with the PCF network element in the cellular network through capability exposure interfaces such as the NEF or N5 interface, or through other cellular network elements, to negotiate tag diversion strategies for passive services. The tag diversion strategy can specifically include diversion filters and diversion strategies / rules. The diversion filter includes tunnel identification information (ID) between the passive IoT server and the NEF or cellular passive management function, the IP information of the service tag reader / writer, the tag ID, and so on. The diversion filter includes uplink and downlink filters. The diversion strategy / rules include whether one or more tags corresponding to a filter support the transparent transmission mode or non-transparent transmission mode of the cellular network, or whether one or more registered tags support diversion between the cellular network and the non-cellular network. In transparent transmission mode, the cellular network does not provide device management or passive service management services for passive devices, but only provides network transmission. In non-transparent transmission mode, in addition to providing cellular network transmission services, the cellular network can also provide device management (such as device authentication and device location management) or passive business management services (such as passive business capability exposure and processing of passive business instructions) for passive devices, rather than just providing network transmission.

[0249] Among them, step a1 is applicable to the scenario where the cellular passive management function is deployed in the cellular network control plane, and the PCF performs the initial label diversion strategy negotiation between the cellular network and the passive system.

[0250] Another process in which the PCF network element determines the label diversion strategy can be implemented by step c1 in Figure 12: the passive service server / passive service platform (passive IoT server) interacts with the cellular passive management function in the cellular network through a capability exposure interface such as NEF to negotiate the label diversion strategy for the passive service. The label diversion strategy includes a diversion filter and a diversion strategy / rule. After the cellular passive management function determines the label diversion strategy, it sends the label diversion strategy to the PCF network element. Among them, the label diversion strategy sent by the cellular passive management function to the PCF can be processed by the cellular passive management function or directly forwarded without processing, which can be determined by the actual situation. Step c1 is applicable to the scenario where the cellular passive management function is deployed in the user plane of the cellular network, and the cellular passive management function acts as the cellular network and the passive system to perform the initial label diversion strategy negotiation.

[0251] Step d12: Storing and maintaining the label diversion policy.

[0252] After the passive IoT server interacts with the cellular network to complete the tag offload policy negotiation, the process of storing and maintaining the tag offload policy information in the passive IoT server may include the following steps, as shown in FIG13 :

[0253] Step A1: The tag registration and activation device sends a tag activation instruction / inventory instruction to the tag.

[0254] The tag registration and activation device can select a specific intermediate device (such as UE, relay device, etc.) within its service range as an activator; or use an activator fixed to the tags in this area as an activator for periodic tag management; or the tag registration and activation device itself can be used as an activator, that is, the tag registration and activation device performs both the roles of reader and activator. The specific choice of activator can be determined by the actual application scenario. In order to ensure the success rate of the inventory, step A1 can be repeated multiple times. In other words, the tag registration and activation device can be a device such as UE / reader / repeater.

[0255] Step A2: The tag responds to the tag activation instruction / inventory instruction and sends a tag activation response / inventory response to the tag registration and activation device.

[0256] Among them, if the tag receives a tag activation instruction, that is, an inventory instruction of a non-existing passive system, the tag can carry one or more of the following information in the response message: 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, mobile type, etc.; tag characteristics, such as high mobility, low mobility, fixed, etc.

[0257] If the tag receives a tag inventory instruction, that is, an inventory instruction of an existing passive system, the tag may carry tag identification information in a response message, including one or more of the following: a temporary identifier, a permanent identifier, a globally unique identifier, and the like.

[0258] Step A3: After receiving the tag activation response / inventory response fed back by the tag, the tag registration activation device initiates a network registration request for the tag.

[0259] The tag registration and activation device can initiate a network registration request for a single tag or for multiple tags. When initiating network registration requests for multiple tags, these requests can be made within the same registration message or in separate registration messages. The registration request message is a NAS message sent by the tag registration and activation device to the cellular network. In the 5G system, it must be sent to the AMF network element via an AN message from the access network device. During this implementation, the tag registration and activation device sends an AN message to the access network device. The AN message includes one or more of the following information: a NAS registration request message, passive tag registration indication information, tag identification information, tag type, tag characteristics, and tag registration and activation device identification. Furthermore, one or more of these information, including passive tag registration indication information, tag identification information, tag type, tag characteristics, and tag registration and activation device identification, may also be included in the NAS registration request message. The NAS registration request message may also carry information related to the passive service platform / server identification (including FQDN, IP address, tunnel ID, etc.). After receiving the AN message, the access network device sends a registration request message to the AMF network element.

[0260] Step A4: The AMF network element sends a label registration request message to the UDM network element.

[0261] Among them, the tag registration request message carries one or more of the access network identification information, AMF identification information, passive tag registration indication information, tag identification information, tag type, tag characteristics and other information.

[0262] Step A5: The UDM network element determines whether the tag can be registered based on the tag information in the tag registration request information sent by the AMF network element; if the UDM network element authentication fails, it replies with a registration rejection response to the AMF network element; if the UDM network element authentication passes, it replies with a registration success response to the AMF network element. At the same time, the UDM network element can reply with the tag service contract information to the AMF network element based on the tag contract information it maintains.

[0263] The tag service contract information may indicate whether one or more registered tags support the transparent transmission mode or non-transparent transmission mode of the cellular network, or whether one or more registered tags support the diversion of cellular and non-cellular networks. In transparent transmission mode, the cellular network does not provide device management or passive business management services for passive devices, but only provides network transmission. In non-transparent transmission mode, the cellular network needs to provide device management (such as device authentication and device location management) or passive business management services (such as passive business capability opening, processing of passive business instructions, etc.) for passive devices, rather than just providing network transmission.

[0264] Step A6: After receiving the registration success response, the AMF network element sends a label policy request to the PCF network element.

[0265] Step A7: The PCF network element sends a label policy response to the AMF network element.

[0266] The tag policy response message includes a tag diversion policy. The tag diversion policy includes a diversion filter and a diversion policy / rule. The diversion filter includes the tunnel ID between the passive IoT server and the NEF or cellular passive management function, the IP information of the service tag reader, the tag ID, etc. The diversion policy / rule includes whether one or more tags corresponding to a filter support the transparent transmission mode or non-transparent transmission mode of the cellular network, or indicates whether one or more registered tags support diversion between cellular networks and non-cellular networks. Step A7 corresponds to the step a2 process in Figure 12.

[0267] Step A8: The AMF network element sends a tag login request to the cellular passive management function.

[0268] The tag registration request is used by the tag to register its status information with the cellular passive management function. The tag registration request carries the tag policy information obtained by the AMF network element from step A5 or step A7.

[0269] Step A9: The cellular passive management function sends a tag registration response to the AMF network element.

[0270] Step A10: The cellular passive management function sends a label policy request to the PCF network element.

[0271] Step A11: The PCF sends a label policy response to the cellular passive management function.

[0272] The tag policy response message includes a tag diversion policy. The tag diversion policy includes a diversion filter and a diversion policy / rule. The diversion filter includes the tunnel ID between the passive IoT server and the NEF or cellular passive management function, the IP information of the service tag reader, the tag ID, etc. The diversion policy / rule includes whether one or more tags corresponding to a filter support the transparent transmission mode or non-transparent transmission mode of the cellular network, or indicates whether one or more registered tags support diversion between cellular networks and non-cellular networks. Step A11 corresponds to step c2 in Figure 12.

[0273] That is, the cellular passive management function stores and maintains the policy according to the label diversion policy obtained in step A8 or A11.

[0274] Step A12: After completing the tag registration, the AMF network element sends a tag registration request response message to the tag registration activation device.

[0275] The message can be forwarded via the RAN. The tag registration request response message includes a tag offload policy. The tag offload policy includes offload filters and offload policies / rules. The offload filter includes the tunnel ID between the passive IoT server and the NEF or cellular passive management function, the IP information of the service tag reader / writer, and the tag ID. The offload policy / rules include whether one or more tags corresponding to a filter support transparent or non-transparent transmission mode on the cellular network, or indicate whether one or more registered tags support offload between cellular and non-cellular networks.

[0276] In other application scenarios, the tag registration and activation devices such as UE / reader / repeater can obtain the tag diversion policy from the AMF network element in step A12, or through step a2 or step b1 shown in Figure 12. The process of step a2 in Figure 12 is as follows: the UE / reader / repeater obtains the tag policy from the policy message or policy update message sent by the PCF network element; the implementation process of step b1 is as follows: the UE / reader / repeater obtains the tag policy from the passive IoT server. In this step, the passive IoT server can send the tag policy to the UE / reader / repeater by means of a tag write instruction.

[0277] That is, the UE / reader / repeater can obtain the tag diversion policy according to step A12, step a2, and step b1 to store and maintain the policy.

[0278] Step d13: Execution of the label offload strategy for the passive service.

[0279] Among them, when downlink diversion is performed, a passive IoT server can be used to perform passive business diversion, or a cellular passive management function can be used to perform passive business diversion.

[0280] Correspondingly, a passive IoT server may implement a tag diversion strategy to achieve tag service transmission, as shown in FIG14 , and may include at least the following steps:

[0281] Step B11: The passive IoT server selects a tag service transmission mode according to the tag offloading strategy / rules obtained in the tag offloading strategy negotiation phase.

[0282] Among them, the passive Internet of Things server determines the filter information in the tag diversion strategy / rule. If the filter information indicates that the target tag of the passive Internet of Things instruction to be sent supports the non-transparent transmission mode, steps B12 to B17 are executed; if the filter information indicates that the target tag of the passive Internet of Things instruction to be sent supports the transparent transmission mode, steps B18 to B19 are executed.

[0283] Step B12: The passive Internet of Things server sends a passive Internet of Things instruction to the cellular passive management function.

[0284] Among them, after receiving the passive Internet of Things instruction, the cellular passive management function can choose to execute step B13 or steps B14 to B17 according to actual conditions.

[0285] Step B13: The cellular passive management function obtains corresponding information from the information stored in the network element corresponding to the cellular passive management function or retrieves corresponding information from other network elements and sends it to the passive Internet of Things server according to the passive Internet of Things instruction.

[0286] Steps B14-B17: The cellular passive management function sends the passive IoT command to the tag through the AMF network element, RAN network element, and tag registration and activation device in sequence, and obtains the corresponding information from the tag.

[0287] Step B18: The passive IoT server sends a passive IoT instruction directly to the tag registration and activation device through the reader IP address.

[0288] The transmission path may be a cellular network (but the cellular network is not aware of the passive service) or a non-cellular network.

[0289] Step B19: The tag registration activation device sends a passive IoT instruction to the tag.

[0290] Correspondingly, a process for implementing a cellular passive management function to execute a tag offload strategy to realize tag service transmission may be shown in FIG15 , and includes at least the following steps:

[0291] Step C11: The passive Internet of Things server sends a passive Internet of Things instruction to the cellular passive management function.

[0292] Step C12: The cellular passive management function selects a tag service transmission mode according to the tag offloading strategy / rule obtained in the tag offloading strategy negotiation phase.

[0293] Among them, according to the filter information in the tag diversion strategy / rule, if the filter information indicates that the target tag of the passive IoT instruction to be sent supports the non-transparent transmission mode, execute steps C13 to C18; if the filter information indicates that the target tag of the passive IoT instruction to be sent supports the transparent mode, execute steps C19 to C20.

[0294] Step C13: The cellular passive management function responds to the passive Internet of Things instruction, and directly retrieves the corresponding information from the information stored in the network element corresponding to the cellular passive management function or retrieves it from other network elements and replies to the passive Internet of Things server.

[0295] In steps C14 to C17, the cellular passive management function sends the passive IoT command to the tag through the AMF network element, the RAN network element, and the tag registration and activation device in sequence, so as to obtain the corresponding information from the tag and reply to the passive IoT server.

[0296] Step C18: The cellular passive management function sends a passive IoT instruction to the tag registration activation device.

[0297] During this process, the cellular network does not perceive the passive service and does not perform any processing, and directly transmits the passive IoT instructions.

[0298] Step C19: The tag registration activation device sends a passive IoT instruction to the tag.

[0299] Correspondingly, a tag registration and activation device includes a UE / repeater / reader / writer executing a tag diversion strategy to implement tag service transmission, as shown in FIG16 , and includes at least the following steps:

[0300] Step D11: The tag registration activation device sends a passive IoT instruction to the tag.

[0301] Among them, step D11 can be executed when the repeater / reader receives a trigger condition from the passive IoT server, the cellular network, or a manual trigger, which can be determined by actual conditions.

[0302] Step D12: The tag sends a passive IoT command response to the tag registration and activation device.

[0303] Step D13: The tag registration and activation device determines the filter information in the tag diversion policy / rule. If the filter information indicates that the tag in the uplink filter supports non-transparent transmission mode, steps D14 to D17 are executed. If the tag in the uplink filter supports transparent transmission mode, step D18 is executed.

[0304] D14-F15, the tag registration activation device sends the tag's passive IoT command response to the cellular passive management function through the AMF network element.

[0305] Step D16: The cellular passive management may determine whether to transmit or process the received passive IoT command response based on the tag diversion strategy information.

[0306] Step D17: The cellular passive management sends a passive IoT command response of the tag to the passive IoT server.

[0307] Step D18: The tag registration activation device directly sends a passive IoT command response message to the passive IoT server.

[0308] The transmission path may be a cellular network (but the cellular network is not aware of the passive service) or a non-cellular network.

[0309] Thus, during the passive service offload strategy execution phase, the UE / reader / repeater performs uplink passive service offload; the cellular passive management function and the passive service platform / server perform downlink passive service offload.

[0310] In this way, the passive IoT server interacts with the policy control function PCF network element in the cellular network through NEF or the cellular passive management function to negotiate the service identification and service differentiation service strategy of the passive service. The PCF network element determines the service differentiation service rules to the reader / receiver / repeater, cellular passive management function and passive service platform during the cellular core network element policy configuration process or the registration process of the passive system equipment in the cellular network. In this way, when the passive service is transmitted in the cellular network, the tag inventory and network transmission in the cellular passive system are differentiated according to different business needs, thereby improving the degree of service refinement and optimizing the service experience while expanding the business scenarios.

[0311] It should be noted that, for the description of the same steps and contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0312] The passive service management method provided in the embodiment of the present application is as follows: after the first label diversion strategy of the passive service is determined by the PCF network element device, the AMF network element device sends a label acquisition request for requesting to obtain the label diversion strategy to the PCF network element device, the core network element device sends a label acquisition request for requesting to obtain the label diversion strategy to the PCF network element device, the PCF network element device receives the label acquisition request for requesting to obtain the label diversion strategy sent by the first policy request device, and sends a label policy response to the first policy request device.
