[0033] It should also be understood that the description of the various embodiments in the present disclosure focuses on the differences between the various embodiments, and the same or similar aspects thereof can be referenced to each other, and for the sake of brevity, they will not be described one by one.

[0034] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0035] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0036] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0037] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0038] In addition, in order to avoid obscuring the present disclosure due to unnecessary details, only the processing steps and / or device structures closely related to at least the scheme according to the present disclosure are shown in the drawings, and other details that are not closely related to the present disclosure are omitted. It should also be noted that similar reference numerals and letters in the drawings indicate similar items, and therefore once an item is defined in one drawing, it does not need to be discussed again for subsequent drawings.

[0039] Passive IoT terminals are completely different from current 3GPP terminals because they do not have batteries and have extremely low power consumption. At the same time, due to the passive characteristics brought about by their ultra-low power consumption, it is difficult for passive IoT terminals to actively initiate requests to access the network and register in the network. In addition, although many passive IoT terminals can store data themselves, they cannot actively initiate requests, so in actual technical implementation, a device with passive IoT terminal reading function is still required to read and transmit data.

[0040] In order to solve the above problems, the present invention firstly expands the passive Internet of Things management function based on the core network access and mobility management function, so that the core network access and mobility management function has the management ability to access and register passive Internet of Things terminals; secondly, based on the core network storage function, an additional registration table is deployed to manage the query of the actual correspondence between the access and mobility management function and the passive Internet of Things terminal, which solves the problem that the passive Internet of Things terminal cannot store the information related to the access and mobility management function, so that the passive Internet of Things cannot actively update the access and registration information during the movement and access process; finally, based on the non-passive Internet of Things terminal that has the passive Internet of Things terminal reading function and has maintained access and registration in the network, a set of access and registration processes for passive Internet of Things terminals are designed, so that the network can fully provide network access and registration services for passive Internet of Things terminals.

[0041] Figure 1 A schematic diagram showing an access registration system for a passive Internet of Things terminal according to some embodiments of the present disclosure.

[0042] like Figure 1 As shown, the system mainly includes: access and mobility management function AMF (passive Internet of Things management function AIMF) network element; network storage function NRF network element; network open function NEF network element; passive Internet of Things related application function AF network element; radio access network (radio access network, RAN) equipment, such as base stations; readers (Reader) of passive Internet of Things terminals; passive Internet of Things terminals.

[0043] Passive IoT terminals are also called ambient IoT terminals. Passive IoT terminals are IoT terminals that do not have SIM cards or batteries and have extremely low power consumption. Due to the passive nature of passive IoT terminals, a device with a reading function is required to read the information inside the passive IoT terminal. Devices with a reading function are designed to be among other terminals with a passive IoT terminal reading function that have been connected and registered in the network.

[0044] Passive IoT terminal reader: mainly refers to non-passive IoT terminals that have the ability to read passive IoT terminals and have been connected and registered in the network. It has the function of reading data from passive IoT terminals based on traditional 3GPP terminals.

[0045] Access and Mobility Management Function (AMF) network element, or passive Internet of Things management function (also called ambient Internet of Things management function (AIMF) network element: In this system, AIMF is a functional module extended based on AMF. Its main function is to be responsible for the access and registration management of passive Internet of Things terminals. It is responsible for maintaining a registry of passive Internet of Things terminals (first registry), which contains the registration information of passive Internet of Things terminals and the correspondence information between passive Internet of Things terminals and readers (first correspondence information).

[0046] Network Repository Function (NRF) network element: In this system, the network repository function NRF network element mainly stores the registry (second registry) of the correspondence information (second correspondence information) between the passive IoT terminals and their readers and the AMF / AIMF network elements. Because AMF / AIMF is generally deployed in a distributed manner in actual deployment, traditional 3GPP terminals generally store the corresponding AMF information in network access for the network side to manage the access and mobility of the terminal. However, since the data volume of the passive IoT terminal is extremely small and the capability is extremely low, the correspondence information between the passive IoT terminal and AMF / AIMF is stored by the NRF network element in this system for query.

[0047] Network Exposure Function (NEF) network element: In this system, it is mainly responsible for forwarding the requests of the AF network element to the corresponding AMF / AIMF network element, and forwarding the instructions and requests from the AMF / AIMF network element to the AF network element.

[0048] Passive IoT related application function (AF) network element: In this system, the AF network element is mainly used to deploy application functions for passive IoT related services. In this system, the AF network element that initiates the access registration request needs to know the terminal information of the requesting party's passive IoT terminal and the corresponding terminal information of the reader with reading capability.

[0049] The disclosed embodiment proposes two access and registration modes for passive IoT terminals based on readers with reading capabilities, one initiated by a reader with reading capabilities and the other initiated by an application function AF network element of a passive IoT service. The following describes these two access and registration methods in detail.

[0050] Figure 2 A schematic diagram of an access registration method for a passive Internet of Things terminal according to some embodiments of the present disclosure is shown, where the access registration is initiated by a reader with reading capability.

[0051] like Figure 2 As shown, the access registration method includes the following steps.

[0052] In step 201, the reader actively initiates an access and registration request for a passive IoT terminal.

[0053] In step 202, the reader reads the registration information of the passive IoT terminal.

[0054] In step 203, the reader receives registration information of the passive Internet of Things terminal returned by the passive Internet of Things terminal.

[0055] In step 204, reporting access and registration request: the reader sends the first access registration request of the passive IoT terminal to the AMF / AIMF network element through the RAN device to request access and registration, which includes the information of the reader and the registration information of the passive IoT terminal read by the reader.

[0056] The information of the reader includes, but is not limited to, the identification information of the reader. The registration information of the passive IoT terminal includes, but is not limited to, the identification information of the reader and other registration information such as model and performance.

[0057] In step 205, the registration table is updated: after receiving the first access registration request, the AMF / AIMF network element updates the first registration table to include the registration information of the passive Internet of Things terminal and the first correspondence information between the passive Internet of Things terminal and the reader, while allowing the passive Internet of Things terminal and the reader to access.

[0058] The first corresponding relationship information may record the identification information of the passive Internet of Things terminal and the identification information of the reader.

[0059] In step 206, synchronous update: the AMF / AIMF network element sends a request to the NRF network element to update the second registration table, which includes information of the reader, information of the passive Internet of Things terminal, and information of the access and mobility management function network element or information of the passive Internet of Things management function network element, and is used to instruct the network storage function network element to update the second registration table to include the second corresponding relationship information of the passive Internet of Things terminal, the reader and the access and mobility management function network element or the passive Internet of Things management function network element.

[0060] Among them, the AMF / AIMF information includes but is not limited to the AMF / AIMF identification information.

[0061] In step 207, the registration table is updated: after receiving the request from the AMF / AIMF network element, the NRF network element updates the second registration table to include second corresponding relationship information of the passive Internet of Things terminal, the reader and the access and mobility management function network element or the passive Internet of Things management function network element.

[0062] Among them, the second corresponding relationship information can record the identification information of the passive Internet of Things terminal, the identification information of the reader, and the identification information of the AMF / AIMF.

[0063] In step 208, access and registration are successful: the NRF network element sends an update success instruction to the AMF / AIMF network element.

[0064] In step 209, access and registration are successful: the AMF / AIMF network element sends an access and registration success instruction to the reader.

[0065] In step 210, the reader determines whether to send the first correspondence information and the access registration success instruction to the application function AF network element related to the service according to the actual service needs.

[0066] The disclosed embodiment utilizes a reader with the ability to read passive IoT terminals, actively reads the registration information of passive IoT terminals, initiates access registration, and expands the passive IoT management function of the access and mobility management function network element, so that it has the management capability of accessing and registering passive IoT terminals, thereby enabling the network to provide access and registration services for passive IoT terminals.

[0067] Figure 3 A schematic diagram of an access registration method for a passive IoT terminal according to some embodiments of the present disclosure is shown, where the access registration is initiated by an AF network element.

[0068] like Figure 3 As shown, the access registration method includes the following steps.

[0069] In step 301, an access and registration request is initiated: the application function AF network element of the passive Internet of Things service sends a second access registration request of the passive Internet of Things terminal to the NEF network element, which includes information of the reader and information of the passive Internet of Things terminal.

[0070] The information of the reader includes, but is not limited to, the identification information of the reader. The information of the passive IoT terminal includes, but is not limited to, the identification information of the reader.

[0071] In step 302, locate and forward related requests: after receiving the request, the NEF network element confirms the information of the actual corresponding AMF / AIMF network element according to the relevant terminal information of the reader, and forwards the second access registration request reported by the AF network element to the AMF / AIMF network element.

[0072] In step 303, the reader is activated: after receiving the relevant request, the AMF / AIMF network element directly sends a second access registration request to the corresponding reader to instruct the reader to read the registration information of the passive Internet of Things terminal and send the first access registration request.

[0073] In step 304, the passive IoT terminal is confirmed: after receiving the relevant request, the reader is activated and reads the registration information of the relevant passive IoT terminal.

[0074] In step 305, after the reader receives the registration information of the passive IoT terminal returned by the passive IoT terminal, after comparing and confirming that the terminal information of the read passive IoT terminal is consistent with the terminal information of the requested passive IoT terminal, it returns the registration information of the passive IoT terminal to the AMF / AIMF network element and requests access and registration.

[0075] In step 306, reporting access and registration request: the reader sends the first access registration request of the passive IoT terminal to the AMF / AIMF network element through the RAN device to request access and registration, which includes the information of the reader and the registration information of the passive IoT terminal read by the reader.

[0076] The information of the reader includes, but is not limited to, the identification information of the reader. The registration information of the passive IoT terminal includes, but is not limited to, the identification information of the reader and other registration information such as model and performance.

[0077] In step 307, the registration table is updated: after receiving the first access registration request, the AMF / AIMF network element updates the first registration table to include the registration information of the passive Internet of Things terminal and the first correspondence information between the passive Internet of Things terminal and the reader, while allowing the passive Internet of Things terminal and the reader to access.

[0078] The first corresponding relationship information may record the identification information of the passive Internet of Things terminal and the identification information of the reader.

[0079] In step 308, synchronous update: the AMF / AIMF network element sends a request to the NRF network element to update the second registration table, which includes information of the reader, information of the passive Internet of Things terminal, and information of the access and mobility management function network element or information of the passive Internet of Things management function network element, and is used to instruct the network storage function network element to update the second registration table to include the second corresponding relationship information of the passive Internet of Things terminal, the reader and the access and mobility management function network element or the passive Internet of Things management function network element.

[0080] Among them, the AMF / AIMF information includes but is not limited to the AMF / AIMF identification information.

[0081] In step 309, the registration table is updated: after receiving the request from the AMF / AIMF network element, the NRF network element updates the second registration table to include second corresponding relationship information of the passive Internet of Things terminal, the reader and the access and mobility management function network element or the passive Internet of Things management function network element.

[0082] Among them, the second corresponding relationship information can record the identification information of the passive Internet of Things terminal, the identification information of the reader, and the identification information of the AMF / AIMF.

[0083] In step 310, access and registration are successful: the NRF network element sends an update success instruction to the AMF / AIMF network element.

[0084] In step 311, access and registration are successful: the AMF / AIMF network element sends an access and registration success instruction to the reader.

[0085] In step 312, the reader or AMF / AIMF network element determines whether to send the first correspondence information and the access registration success instruction to the service-related application function AF network element according to actual service needs.

[0086] In the disclosed embodiment, the AF network element initiates access registration, uses a reader with the ability to read passive IoT terminals, activates and reads the registration information of passive IoT terminals, and expands the passive IoT management function of the access and mobility management function network element, so that it has the management capability of accessing and registering passive IoT terminals, thereby enabling the network to provide access and registration services for passive IoT terminals.

[0087] The related art does not have access and registration specifications designed for passive and passive devices such as passive IoT terminals. The disclosed embodiment designs an access and registration service process and specifications for passive IoT terminals based on non-passive IoT terminals that have the ability to read passive IoT terminals and have been connected and registered in the network.

[0088] Since non-passive IoT terminals with passive IoT terminal reading capabilities are deployed, which have been connected to and registered in the network, and passive IoT terminals cannot always maintain connection with the network due to their passive and passive characteristics, in order to enable the network side to quickly request relevant passive IoT terminals, the disclosed embodiment designs and deploys a set of registration tables on the AMF / AIMF side, so that the network can query the terminals with reading functions, which are connected to the network or can be activated at any time, corresponding to the passive IoT terminals that need to be requested, and then access the specific passive IoT terminals.

[0089] Since the amount of data stored in the passive Internet of Things terminal is extremely small, in order to enable the passive Internet of Things terminal to keep updating the corresponding relationship information between the passive Internet of Things terminal and the corresponding reader and AMF / AIMF during the actual access and registration process, the embodiment of the present disclosure designs and deploys two registration tables located on the AMF / AIMF and NRF sides respectively, so that the network can accurately query the AMF / AIMF and reader corresponding to the passive Internet of Things terminal.

[0090] In order to adapt to the future deployment and implementation of passive Internet of Things, the disclosed embodiment is first based on the non-passive Internet of Things terminal with passive Internet of Things terminal reading function that has maintained access and registration in the network, and then expands the passive Internet of Things terminal management function AIMF on the basis of the core network access and mobility management function AMF, and finally deploys a registration table in the core network storage function, and designs a set of service process specifications for terminal access and registration of passive Internet of Things, which solves the problem that passive Internet of Things terminals cannot directly access the network or actively respond to network requests and initiate terminal registration to the network.

[0091] In the future, when the passive Internet of Things technology matures and needs to be deployed on a large scale, when the existing network needs to perform relevant business deployment and technology upgrades for the passive Internet of Things business, the solution of the embodiment of the present disclosure and the corresponding service process specification can be deployed to the relevant network, so that the network can effectively provide the corresponding network services for the passive Internet of Things terminal.

[0092] Since the manufacturing cost of passive IoT terminals is extremely low, they can be deployed in large quantities and on a large scale to provide access and registration services for a huge number of passive IoT terminals. Through this service, network and related data services can be provided to a large number of terminals and third-party service providers, which has huge commercial prospects and value.

[0093] Although the capabilities of traditional 3GPP terminals are far behind those of base stations, UEs (readers) with reading capabilities play a relay role in passive IoT. In addition, UEs (readers) can be deployed in large numbers over a wide range, which can further expand the coverage of actual passive IoT deployments compared to base stations. At the same time, the network coverage within the same range can support more passive IoT terminals and provide them with corresponding network and data services.

[0094] The disclosed embodiment designs a set of terminal access and registration methods for passive IoT terminals, and defines service process specifications for access and registration.

[0095] The disclosed embodiment designs and deploys a terminal with a reading function for a passive IoT terminal, that is, a non-passive IoT terminal that has the ability to read a passive IoT terminal and has been connected and registered in the network.

[0096] The disclosed embodiment designs a passive Internet of Things management function for managing passive Internet of Things terminals for passive Internet of Things services based on the access and mobility management function.

[0097] The disclosed embodiment designs two corresponding registration tables which are respectively deployed in the passive Internet of Things management function and the network storage function in the access and mobility management function.

[0098] The registry of the passive IoT management function deployed in the access and mobility management function mainly maintains the access and registration information of the passive IoT terminals in the network and the corresponding information between the passive IoT terminals and the non-passive IoT terminals that have the passive IoT terminal reading capability and have maintained access and registered in the network.

[0099] The registry deployed in the network storage function mainly maintains the corresponding information of passive IoT terminals and AMF / AIMF.

[0100] The passive IoT management function in the access and mobility management function also stores the terminal detailed configuration information of non-passive IoT terminals that have passive IoT terminal reading capabilities and have maintained access and registered in the network.

[0101] The access registration device includes, for example, a reader, an access and mobility management function network element, or a passive Internet of Things management function network element.
