[0035] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the technical solution of the present application is further elaborated in detail below in combination with the drawings and specific embodiments of the specification. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0036] Unless otherwise defined, all technical and scientific terms used in the embodiments of the present application have the same meaning as those commonly understood by those skilled in the art to which the present application belongs. The terms used in the embodiments of the present application are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.

[0037] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict. It should also be noted that the terms "first / second / third" involved in the embodiments of the present application are only used to distinguish similar objects and do not represent a specific ordering of the objects. It is understandable that "first / second / third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0038] Before introducing the embodiments of the present application, a basic architecture of a passive Internet of Things network in the related art is briefly introduced.

[0039] Among the related technologies, passive Internet of Things technology is limited by the extremely low power consumption and complexity of passive tags, and has the problem of transmission distance less than 10 meters and difficulty in large-scale networking. Ambient Internet of Things (AmbientIoT) devices use cellular base stations to directly connect or relay communications with tags to further increase the excitation distance and receiving distance, optimize system efficiency, and cope with networking and application requirements in larger ranges and more complex scenarios.

[0040] Ambient IoT devices: use cellular base stations to connect directly to tags or communicate through relays, and wireless radio frequency signals are acquired through the environment or signals from other devices.

[0041] Energy source: low-capacity battery or obtained from the environment, such as radio frequency (RF) signals, solar energy, vibration, thermal energy, etc.

[0042] In related technologies, 5G networks use base stations or relay devices to implement energy excitation and interaction of passive tags. Figure 1 As shown, specifically, the passive tags are inventoried sequentially through the application layer function (Application Function, AF), the network exposure function (Network Exposure Function, NEF), the access and mobility management function (Access and Mobility Management Function, AMF), and the base station.

[0043] In the process of inventory management of passive IoT devices (such as passive tags), the passive Internet of Things needs to comprehensively consider the short communication cycle of passive tags, unstable communication, and other comprehensive factors. At the same time, the information carried by passive tags is limited, which limits the use of passive tags by communication networks. The 3rd Generation Partnership Project (3GPP) network needs to have the ability to quickly inventory multiple passive tags individually or by region according to tag identification to reduce the number of signaling interactions between tags and the network.

[0044] In response to the above requirements, the relevant protocols have not yet provided relevant procedures to address the above requirements.

[0045] In the embodiments of the present application, the design is mainly aimed at the rapid inventory implementation process of passive IoT tags to solve the scenarios that cannot be solved by analog RFID.

[0046] In some protocols, the more common label format is as follows:

[0047] Electronic Product Code (EPC) code area: The information in the EPC code area is readable and writable, indicating the electronic identification and is the main information to be read.

[0048] Tag identification (TagID, TID) area: stores the ID number set by the tag manufacturer, which is readable but not writable.

[0049] User area: user-definable area, which is readable and writable

[0050] Password area: There are 32 bits (which can be expressed as bits) access password and 32 bits destruction password.

[0051] According to the current progress of the protocol, there is still a problem. That is, when using the communication network as a passive tag access method, compared with RFID technology, the core network needs to simplify the interaction process to improve inventory efficiency. This is also one of the important research scenarios in the passive Internet of Things scenario.

[0052] In the 3GPP protocol, two research topics are defined:

[0053] 1. Key Issue #2: Identification, Subscription, Registration and Connection management

[0054] Considering that Ambient IoT Devices are a new type of reduced capabilities devices, the existing subscription model may not be suitable. Specifically, there is the need to study the device identification method to support Ambient IoT devices which are under operator control.

[0055] (1) Study whether subscription management, registration management and / or connection management are necessary for an Ambient IoT Device or a group of Ambient IoT Devices, and if so identify the necessary state machine(s), procedures and functionality considering the Ambient IoT Devices capability and characteristics.

[0056] (2) Study whether and how reachability and paging apply to Ambient IoT Device(s)considering the AmbientIoT devices capability and characteristics,and if so,what are the impacts.

[0057] (3) Study how to identify Ambient IoT Device or group of devices and how to format the identifier.

[0058] 2. Key Issue #3: Support of Ambient IoT Services

[0059] Description (in English, it can be expressed as Description)

[0060] This Key Issue pertains to the AIoTservices. Considering that AIoT Devices are a new type of devices with reduced capabilities, the following need to be supported:

[0061] Inventory (which can be expressed as Inventory in English).

[0062] Command (which can be expressed as Command in English).

[0063] In an embodiment of the present application, in response to the above-mentioned scenario requirements, a method for rapid inventory of passive IoT tags based on a communication network is proposed, which simplifies the interaction between the communication network and the passive IoT tags. The key point is that the 3GPP network needs to support the sending of rapid inventory messages, that is, through a single signaling interaction, it can support the simultaneous reading of TID area, User area, authentication file, EPC and other information. The subsequent network side can trigger the check of the authentication result of the passive IoT tag, and determine whether the EPC data needs to be reported based on the authentication result. It can be seen that there is no need to interact with the passive IoT tag during the subsequent authentication and EPC data reporting operations.

[0064] The specific implementation of the embodiment of this application is as follows:

[0065] The present application embodiment provides an inventory method, such as Figure 2 As shown, applied to the first network function, the method may include:

[0066] S201. A first network function sends a first request to a first device.

[0067] In an embodiment of the present application, the first network function may be AMF or TMF.

[0068] Among them, TMF can be understood as the network element of the core network that processes the perception tag service.

[0069] In the embodiment of the present application, the first device may be a passive device, such as a passive electronic tag.

[0070] In the embodiment of the present application, the first request is a tag quick inventory request.

[0071] In the embodiment of the present application, to implement the inventory method, the passive electronic tag (i.e., the first device) must meet the following prerequisites:

[0072] In some embodiments, the electronic tag generally includes four areas, namely, a TID area (this area generally stores the TID), a User area (this area generally stores the device ID), an EPC area (this area generally stores the electronic tag information), and a password area.

[0073] In the embodiment of the present application, the TID area, the User area, or the password area is improved, and the improved contents are as follows:

[0074] (1) The User area can be set with identification information device ID that can be controlled by the operator. Its definition format can include: application vendor information (AF), operator information (network provider), code number information (this part can be set as quick inventory identification information) and / or quick inventory authorization code information. The relevant information has been written into the electronic tag before use.

[0075] (2) The password area can be used to set the quick inventory authorization code information. That is, the quick inventory authorization code information can be stored in the User area or in the password area. If it is set in the password area, it should be written when the electronic tag leaves the factory. At this time, the quick inventory identification information can be enhanced in the TID.

[0076] In the embodiment of the present application, before the AMF or TMF sends the first request to the passive device, the following process may be performed:

[0077] 1. AF sends a tag inventory request to NEF, which carries inventory identification information (also called quick inventory identification information) and / or inventory authorization code information (also called quick inventory authorization code information), and may also carry inventory target area information, target tag cooperative operator or tag application party list, etc.

[0078] It should be noted that the inventory target area information may be geographic area information. After the NEF receives the inventory target area information sent by the AF, the NEF maps the geographic area information into a tracking area (TA) or Cell information identifiable by the network.

[0079] It should be noted that the inventory identification information may refer to a digital sequence of 1 to n digits, and may be fixedly set to a certain value according to the requirements of the end-to-end agreement.

[0080] It should be noted that the inventory authorization code information can also be a string of digital sequences, which is equivalent to the function of a password.

[0081] 2. NEF sends a passive tag area quick inventory request to AMF or TMF. The request carries inventory identification information and / or inventory authorization code information, and may also carry inventory target area information, tag cooperative operators or tag application party lists.

[0082] It should be noted that the information of the tag cooperation operator or tag application list is included in the device ID. In addition, the tag cooperation operator or tag application list is based on the service agreement between the operator and other operators or tag application parties, and supports the activation and reading of relevant passive electronic tag data; this information needs to be configured in the NEF.

[0083] It should be noted that the label cooperation operator or label application party list in step 2 is obtained by finding the intersection of the target label cooperation operator or label application party list sent by the AF in step 1 and the label cooperation operator or label application party list supported by the current network configured on the NEF.

[0084] In an embodiment of the present application, the AMF or TMF sends a first request to the first device, which may be that the AMF or TMF selects a base station or terminal (i.e., user equipment (User Equipment, UE)) according to the inventory target area information, and sends a passive tag quick inventory request to the selected base station or terminal. The request carries inventory identification information and / or inventory authorization code information, and may also carry a list of tag cooperation operators or tag application parties.

[0085] In the embodiment of the present application, energy incentive and a first request are sent to a first device (ie, a passive device) through a base station or a UE, and the first request may be a tag quick inventory request.

[0086] In the embodiment of the present application, the first request carries inventory identification information and / or inventory authorization code information, so that the first device can determine whether to support fast inventory based on the inventory identification information and / or inventory authorization code information.

[0087] S202: Receive tag identification information, authentication information, and electronic identification information of the first device sent by the first device based on the first request.

[0088] In the embodiment of the present application, the electronic identification information is the EPC information of the EPC area.

[0089] In the embodiment of the present application, the authentication information includes authentication data and device ID.

[0090] In the embodiment of the present application, the tag identification information is the TID information stored in the TID area.

[0091] In an embodiment of the present application, when the first device (ie, a passive electronic tag) determines that it supports fast inventory, the first device responds to the first request, and the first device simultaneously reports TID information, authentication data, device ID, and EPC information to the AMF or TMF.

[0092] In an embodiment of the present application, the AMF or TMF simultaneously receives the TID information, authentication data, device ID and EPC information reported by the first device through one interaction.

[0093] S203: Send the tag identification information and the authentication information to the second network function, and receive an authentication result sent by the second network function based on the tag identification information and the authentication information.

[0094] In the embodiment of the present application, the second network function is a unified data management (UDM) or an authentication authorization accounting server (AAA).

[0095] In an embodiment of the present application, the AMF or TMF sends an authentication request to the UDM or AAA, and the authentication request carries TID information, authentication data and / or device ID.

[0096] In the embodiment of the present application, the number of UDM or AAA can be one or more. Since the authentication information includes device information (ie, device ID), the target second network function can be determined from one or more second network functions based on the device information.

[0097] In the embodiment of the present application, the AMF or TMF determines the target UDM or target AAA according to the label cooperation operator or label application provider list information in the device ID of the User area.

[0098] In an embodiment of the present application, the AMF or TMF sends an authentication request to the target UDM or target AAA, where the request carries TID information, authentication data and / or deviceID, and authentication is performed through the target UDM or target AAA.

[0099] In this embodiment of the present application, after the UDM or AAA, or the target UDM or target AAA completes the authentication, it returns the authentication result to the AMF or TMF.

[0100] In an embodiment of the present application, AMF or TMF receives the authentication result and determines whether to report the electronic identification information based on the authentication result.

[0101] S204: When the authentication result is successful, report the electronic identification information.

[0102] In the embodiment of the present application, the electronic identification information is EPC information.

[0103] In an embodiment of the present application, the AMF or TMF determines whether to report, save or discard the EPC information reported by the current passive electronic tag based on the authentication result.

[0104] In the embodiment of the present application, AMF or TMF supports first receiving TID information, authentication data, device ID, EPC information, and carrying TID information, authentication data and / or device ID to UDM or AAA authentication. If the authentication is passed, the EPC information reported by the current passive electronic tag is reported or saved.

[0105] In the embodiment of the present application, if the authentication result is authentication failure, the electronic identification information is ignored / discarded. That is, it can be understood that if the authentication fails, the EPC information reported by the current passive electronic tag can be ignored / discarded.

[0106] It can be understood that in an inventory method provided in an embodiment of the present application, after the first network function sends a first request to the first device, the first device can simultaneously send authentication information and electronic identification information to the first network function according to the received first request. Because the authentication information and the electronic identification information are sent through one information interaction, the first network function only needs to directly report the received electronic identification information after receiving the authentication success message sent by the second network function. In this way, the number of interactions between the first network function and the first device is reduced, thereby improving the inventory efficiency of the first device.

[0107] In one embodiment of the present application, the electronic identification information is unencrypted electronic identification information or electronic identification information encrypted using the electronic identification information and password area information of the first device.

[0108] In an embodiment of the present application, when the first device reports EPC information to AMF or TMF, it may directly report unencrypted EPC information to AMF or TMF.

[0109] In an embodiment of the present application, if there are EPC security requirements, the first device supports lightweight encryption operations on the EPC information before reporting the EPC information in the fast inventory mode, that is, in the fast inventory mode, when TID information, authentication data, device ID and EPC information are reported at the same time, the EPC information in the EPC area can first support an XOR operation between the EPC information and the access password in the password area, perform a preliminary encryption operation, and report the encrypted EPC information to the AMF or TMF.

[0110] The present application also provides an inventory method, such as Figure 3 As shown, applied to a first device, the method may include:

[0111] S301. Receive a first request sent by a first network function.

[0112] In an embodiment of the present application, the first network function is AMF or TMF.

[0113] In the embodiment of the present application, the first request is a tag quick inventory request.

[0114] In the embodiment of the present application, the first device is a passive device (such as a passive electronic tag).

[0115] In an embodiment of the present application, the AMF or TMF sends a tag quick inventory request to the passive device through the base station or UE.

[0116] S302: Based on the first request, send tag identification information, authentication information, and electronic identification information of the first device to the first network function.

[0117] In the embodiment of the present application, the first request carries inventory identification information and / or inventory authorization code information.

[0118] In an embodiment of the present application, when the tag identification information, authentication information, and electronic identification information of the first device are sent to the first network function based on the first request, it can be determined whether the first device supports fast inventory based on the inventory identification information and / or the inventory authorization code information; if the first device supports fast inventory, the tag identification information, authentication information, and electronic identification information are sent to the first network function.

[0119] In the embodiment of the present application, the first device (such as a passive electronic tag) receives a stimulus and first checks whether it supports fast inventory.

[0120] In an embodiment of the present application, after the first device receives the inventory identification information and / or inventory authorization code information sent by the AMF or TMF, it can first search in the four areas contained in itself, and if the first device has the inventory identification information and / or the inventory authorization code information, determine that the first device supports quick inventory; or, if the first device does not have the inventory identification information and the inventory authorization code information, determine that the first device does not support quick inventory.

[0121] It should be noted that when the first device determines whether it supports quick inventory, if the first device has both inventory identification information and inventory authorization code information, it can first determine whether the passive electronic tag supports quick inventory by checking whether there is an inventory identification, and then determine whether a quick inventory response is required by comparing the inventory authorization code information. In this way, security will be higher.

[0122] If only the inventory identification information or the inventory authorization code information exists, then only a single check and confirmation of the inventory identification information or the inventory authorization code information is required, but the security is slightly worse in this case.

[0123] In an embodiment of the present application, after the first device checks and determines that fast inventory is supported, the first device reports TID information, authentication data, device ID and EPC information to AMF or TMF at the same time.

[0124] It should be noted that in the embodiment of the present application, the first device reports all information (ie, TID information, authentication data, device ID and EPC information) to AMF or TMF at one time. In this case, the first device only needs to interact with the network side once.

[0125] It can be understood that in an inventory method provided in an embodiment of the present application, after the first network function sends a first request to the first device, the first device can simultaneously send authentication information and electronic identification information to the first network function according to the received first request. Because the authentication information and the electronic identification information are sent through one information interaction, the first network function only needs to directly report the received electronic identification information after receiving the authentication success message sent by the second network function. In this way, the number of interactions between the first network function and the first device is reduced, thereby improving the inventory efficiency of the first device.

[0126] In one embodiment of the present application, the electronic identification information is unencrypted electronic identification information or electronic identification information encrypted using the electronic identification information and password area information of the first device.

[0127] In an embodiment of the present application, if there are EPC security requirements, the first device supports lightweight encryption operations on the EPC information before reporting the EPC information in the fast inventory mode, that is, in the fast inventory mode, when TID information, authentication data, device ID and EPC information are reported at the same time, the EPC information in the EPC area can first support an XOR operation between the EPC information and the access password in the password area, perform a preliminary encryption operation, and report the encrypted EPC information to the AMF or TMF.

[0128] In one embodiment of the present application, the inventory identification information is set in the user area or TID area of ​​the first device; the inventory authorization code information is set in the user area or password area of ​​the first device.

[0129] It should be noted that the configuration of the inventory identification information and the inventory authorization code information in the first device may refer to the configuration described in the aforementioned first network function side embodiment, which will not be repeated here.

[0130] It should be noted that, since the first device can make improvements to the user area or the password area, the first device can determine whether it supports fast inventory when receiving an inventory request.

[0131] Based on the above embodiments, the present application also provides a schematic diagram of the overall process of the inventory method, such as Figure 4 As shown, the specific steps include:

[0132] S1. AF sends a tag inventory request to NEF, which carries inventory identification information and / or inventory authorization code information, inventory target area information, and a list of target tag cooperative operators or tag application parties.

[0133] S2. NEF sends a passive tag area quick inventory request to AMF or TMF, which carries inventory identification information and / or inventory authorization code information, inventory target area information, and a list of tag cooperation operators or tag application parties.

[0134] S3, AMF or TMF selects a base station or terminal according to the inventory target area information, and sends a passive tag quick inventory request, which carries inventory identification information and / or inventory authorization code information, a list of tag cooperation operators or tag application parties.

[0135] S4. The base station or the terminal sends an energy stimulus and a tag fast inventory request to the passive device, where the request carries inventory identification information and / or inventory authorization code information.

[0136] S5. The passive device receives energy stimulation and determines whether to support quick inventory based on the inventory identification information and / or the inventory authorization code information.

[0137] S6. If the passive device supports fast inventory, it reports TID information, authentication data, deviceID and EPC information to AMF or TMF at the same time.

[0138] S7. AMF or TMF sends an authentication request to the corresponding UDM or AAA, which carries TID information, authentication data and / or device ID.

[0139] S8. UDM or AAA returns the authentication result to AMF or TMF.

[0140] S9. AMF or TMF determines whether to report, save or discard the EPC information reported by the current passive device based on the authentication result.

[0141] S10. Within the specified time, steps S4 to S9 can be repeated. AMF or TMF can perform a single or aggregate authentication of the successfully authenticated TID and EPC information and report it to AF.

[0142] Based on the above embodiments, the embodiments of the present application can realize the rapid inventory of passive electronic tags. The key point is to introduce the definition and processing mechanism of inventory identification information (also called rapid inventory identification information) and / or inventory authorization code information (also called rapid inventory authorization code information). Passive electronic tags need to support the setting and processing of relevant information, and support the simultaneous reporting of TID, authentication data, User area information, and EPC information. The 3GPP network needs to support the sending of tag rapid inventory messages. It can first read the TID information, deviceID, authentication data, and EPC information in full. The network side will then trigger the authentication process for the passive electronic tags, and can check the tag authentication results, and determine whether the EPC information needs to be reported based on the authentication results.

[0143] Based on the above embodiments, the key points in the embodiments of the present application can be summarized as follows:

[0144] 1. Passive electronic tags should support the setting, identification, and processing of rapid inventory identification information and / or rapid inventory authorization code information to determine whether rapid inventory operations are supported. If rapid inventory is supported, the full amount of information of the tag should be reported at the same time. The full amount of information refers to TID information, authentication data, deviceID, and EPC information in the EPC area.

[0145] 2. The quick inventory identification information is defined in the User area, which can be defined by the communication operator and / or the label application provider. The quick inventory authorization code information should be defined in the password area or the User area. If it is in the password area, the label is set by default when it leaves the factory. If it is in the User area, it can be defined by the communication operator and / or the label application provider.

[0146] 3. Passive electronic tags support lightweight encryption of EPC information before reporting data in the fast inventory mode, that is, they support XOR operation between the EPC code and the password area access password for encryption operation.

[0147] 4. AMF or TMF should support the rapid inventory method for passive electronic tags, support sending tag rapid inventory requests to base stations or terminals, carry rapid inventory identification information and / or rapid inventory authorization code information; and support executing rapid inventory operations on tags, and support simultaneous caching of TID, authentication data, deviceID, and EPC information.

[0148] 5. AMF or TMF should support fast reception of all information reported by tags at the same time, and support carrying partial information to trigger the authentication process, and determine whether to report EPC information based on the authentication results.
