[0039] Passive IoT terminal is completely different from the existing 3GPP terminal due to its characteristics such as no battery and extremely low power consumption. At the same time, due to the passive characteristics brought by the extremely low power consumption, the passive IoT terminal is difficult to actively initiate a request to access the network and register in the network. In addition, although many passive IoT terminals can store data by themselves, due to the inability to actively initiate a request, in the actual technical implementation, a device with passive IoT terminal reading function is still needed to read and transmit data.

[0040] To solve the above problems, the present disclosure first extends the passive IoT 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 capability of accessing and registering the passive IoT terminal. Secondly, based on the core network 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 IoT terminal, solve the problem that the passive IoT terminal cannot store the access and mobility management function related information, so that the passive IoT cannot actively update the access and registration information in the process of moving and accessing. Finally, based on the non-passive IoT terminal with passive IoT terminal reading function which has maintained access and registration in the network, a set of access and registration process for passive IoT terminal is designed, so that the network can completely provide network access and registration services for passive IoT terminal.

[0041] Figure 1 A schematic diagram of an access and registration system of a passive IoT terminal according to some embodiments of the present disclosure is shown.

[0042] As Figure 1 shown, the system mainly includes: an access and mobility management function AMF (passive IoT management function AIMF) network element; a network storage function NRF network element; a network exposure function NEF network element; a passive IoT related application function AF network element; a radio access network (RAN) device such as a base station; a passive IoT terminal reader (Reader); and a passive IoT terminal.

[0043] The passive IoT terminal, also known as an Ambient IoT terminal, is a kind of IoT terminal without SIM card and battery, with extremely low power consumption. Due to the passive characteristics of the passive IoT terminal, a device with reading function is needed to read the information inside the passive IoT terminal. The device with reading function is designed among other terminals with passive IoT terminal reading function which have accessed and registered in the network.

[0044] Reader of passive IoT terminal: mainly refers to a non-passive IoT terminal which has the ability to read passive IoT terminals, has maintained access in the network and has been registered. It has the function of reading data of passive IoT terminals on the basis of traditional 3GPP terminals.

[0045] Access and Mobility Management Function (AMF) network element, or passive IoT management function (also known as Ambient IoT Management Function (AIMF) network element: in the 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 IoT terminals, and it is responsible for maintaining a registration table (first registration table) of passive IoT terminals. The registration table contains the registration information of the passive IoT terminal and the corresponding relationship information (first corresponding relationship information) of the passive IoT terminal and the reader.

[0046] Network Repository Function (NRF) network element: in the system, the Network Repository Function (NRF) network element mainly stores the registration table (second registration table) of the corresponding relationship information (second corresponding relationship information) of the passive IoT terminal and its reader and the AMF / AIMF network element. Because AMF / AIMF is generally deployed in a distributed manner in actual deployment, and traditional 3GPP terminals generally store information corresponding to AMF for network side management of terminal access and mobility during network access. However, since the data volume of passive IoT terminals is extremely small and the capability is extremely low, the corresponding information of passive IoT terminals and AMF / AIMF is stored by the NRF network element in the system for query.

[0047] Network Exposure Function (NEF) network element: in the system, it is mainly responsible for forwarding the request 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 the system, the AF network element is mainly to deploy application functions for passive IoT related services. In the system, the AF network element initiating the access registration request needs to know the terminal information of the passive IoT terminal and the corresponding terminal information of the reader with reading capability.

[0049] The embodiments of the present disclosure propose two access and registration modes of the passive Internet of Things terminal based on the reading capability of the reader, one of which is initiated by the reader with reading capability, and the other is initiated by the application function (AF) network element of the passive Internet of Things service. The two access and registration methods are described in detail as follows.

[0050] Figure 2 The schematic diagram of the access and registration method of the passive Internet of Things terminal of some embodiments of the present disclosure is shown, which is initiated by the reader with reading capability.

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

[0052] In step 201, the reader initiates the access and registration request of the passive Internet of Things terminal.

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

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

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

[0056] For example, the information of the reader includes but is not limited to the identification information of the reader. For example, the registration information of the passive Internet of Things terminal includes but is not limited to the identification information of the reader and the model, performance and other registration information.

[0057] In step 205, the registration table is updated: after receiving the first access and 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 corresponding relationship information of the passive Internet of Things terminal and the reader in the case of allowing the passive Internet of Things terminal and the reader to access.

[0058] For example, the first corresponding relationship information can record the identification information of the passive Internet of Things terminal and the identification information of the reader.

[0059] ​In step 206, a synchronous update: the AMF / AIMF network element sends a request to update the second registry to the NRF network element, including the information of the reader, the information of the passive Internet of Things terminal, and the information of the access and mobility management function network element or the information of the passive Internet of Things management function network element, for indicating the network storage function network element to update the second registry to include the second correspondence information of the passive Internet of Things terminal, the reader, the access and mobility management function network element, or the passive Internet of Things management function network element.

[0060] The information of the AMF / AIMF includes but is not limited to the identification information of the AMF / AIMF.

[0061] In step 207, a registry update: after receiving the request of the AMF / AIMF network element, the NRF network element updates the second registry to include the second correspondence information of the passive Internet of Things terminal, the reader, the access and mobility management function network element, or the passive Internet of Things management function network element.

[0062] The second correspondence 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, an access and registration success: the NRF network element sends an update success instruction to the AMF / AIMF network element.

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

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

[0066] The embodiments of the present disclosure utilize the reader with the passive Internet of Things terminal reading capability to actively read the registration information of the passive Internet of Things terminal and initiate the access registration, expand the passive Internet of Things management function of the access and mobility management function network element, and make it have the management capability of the access and registration of the passive Internet of Things terminal, so as to realize the network providing the access and registration service for the passive Internet of Things terminal.

[0067] Figure 3 A schematic diagram of the access registration method of the passive Internet of Things terminal is shown, which is initiated by the AF network element.

[0068] As shown in Figure 3 The access registration method includes the following steps.

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

[0070] The information of the reader, for example, includes but is not limited to identification information of the reader. The information of the passive Internet of Things terminal, for example, includes but is not limited to identification information of the reader.

[0071] In step 302, a positioning forwarding related request is forwarded: after receiving the request, the NEF network element confirms the information of the actual corresponding AMF / AIMF network element according to the related 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 related request, the AMF / AIMF network element directly sends the second access registration request to the corresponding reader, which is used 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 Internet of Things terminal is confirmed: after receiving the related request, the reader is activated, and the registration information of the related passive Internet of Things terminal is read,

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

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

[0076] The information of the reader, for example, includes but is not limited to identification information of the reader. The registration information of the passive Internet of Things terminal, for example, includes but is not limited to 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 corresponding relationship information of the passive Internet of Things terminal and the reader, in the case of allowing the passive Internet of Things terminal and the reader to access.

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

[0079] In step 308, synchronization update: the AMF / AIMF network element sends a request for updating the second registry to the NRF network element, including the information of the reader, the information of the passive Internet of Things terminal, and the information of the access and mobility management function network element or the information of the passive Internet of Things management function network element, for indicating the network storage function network element to update the second registry to the second correspondence relationship information including 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] The information of the AMF / AIMF includes but is not limited to the identification information of the AMF / AIMF.

[0081] In step 309, registry update: after receiving the request of the AMF / AIMF network element, the NRF network element updates the second registry to the second correspondence relationship information including 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] The second correspondence 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 success: the NRF network element sends an update success instruction to the AMF / AIMF network element.

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

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

[0086] The embodiment of the present disclosure initiates access registration by the AF network element, activates and reads the registration information of the passive Internet of Things terminal by using the reader with the reading capability of the passive Internet of Things terminal, extends the passive Internet of Things management function of the access and mobility management function network element, and makes it have the management capability of access and registration of the passive Internet of Things terminal, so as to realize the network providing access and registration service for the passive Internet of Things terminal.

[0087] The related art does not have access and registration related specifications designed for such passive and passive devices as passive Internet of Things terminals. The embodiment of the present disclosure designs an access and registration service process and specification for passive Internet of Things terminals based on non-passive Internet of Things terminals with passive Internet of Things terminal reading capability, which have maintained access and have registered in the network.

[0088] Since the non-passive Internet of Things terminal with passive Internet of Things terminal reading capability has maintained access and has registered in the network, and the passive Internet of Things terminal cannot always maintain connection with the network due to its passive and passive characteristics, in order for the network side to quickly request the related passive Internet of Things terminal, the embodiment of the present disclosure designs a set of registration table on the AMF / AIMF side, so that the network can query the passive Internet of Things terminal corresponding to the passive Internet of Things terminal to be requested. The terminal with reading function maintains connection with the network or can be activated at any time, and then accesses the specific passive Internet of Things terminal.

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

[0090] In order to adapt to the deployment and implementation of future passive Internet of Things related technologies, the embodiment of the present disclosure first extends the passive Internet of Things terminal management function AIMF based on the non-passive Internet of Things terminal with passive Internet of Things terminal reading function which has maintained access and registration in the network, and then extends the passive Internet of Things terminal management function AIMF based on the core network access and mobility management function AMF. Finally, the registration table is deployed in the core network storage function, and a set of terminal access and registration service process specifications for passive Internet of Things are designed, which solves the problem that the passive Internet of Things terminal cannot directly access the network or actively respond to the network request, and initiates terminal registration to the network.

[0091] When the existing network needs to deploy related services and upgrade technologies for passive Internet of Things services, the scheme and the corresponding service process specification of the embodiment of the present disclosure can be deployed in the related network, so that the network can effectively provide corresponding network services for passive Internet of Things terminals.

[0092] Since the passive Internet of Things terminal has extremely low manufacturing cost, a large number of passive Internet of Things terminals can be deployed to provide access and registration services for a large number of passive Internet of Things terminals, and through the services, a large number of terminals and third-party service providers can be provided with network and related data services, which has great commercial prospects and value.

[0093] Although the capability of the conventional 3GPP terminal is greatly different from that of the base station, since the UE (reader) with reading capability plays a role of relay in the passive Internet of Things, and the UE (reader) can be deployed in a large range, compared with the base station, the coverage in the actual passive Internet of Things deployment can be further expanded, and the network coverage in the same range can support more passive Internet of Things terminals and provide corresponding network and data services for the passive Internet of Things terminals.

[0094] The embodiment of the present disclosure designs a set of terminal access and registration methods for passive Internet of Things terminals, and defines the service process specification of access and registration.

[0095] The embodiment of the present disclosure designs a terminal with reading function for passive Internet of Things terminals, that is, a non-passive Internet of Things terminal with passive Internet of Things terminal reading capability, which has maintained access and has been registered in the network.

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

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

[0098] The registration table of the passive Internet of Things management function deployed in the access and mobility management function mainly maintains the access and registration information of the passive Internet of Things terminal in the network and the corresponding information of the passive Internet of Things terminal and the non-passive Internet of Things terminal with passive Internet of Things terminal reading capability, which has maintained access and has been registered in the network.

[0099] The registration table deployed in the network storage function mainly maintains the corresponding information of the passive Internet of Things terminal and the AMF / AIMF.

[0100] The passive Internet of Things management function in the access and mobility management function also stores the terminal detailed configuration information of the non-passive Internet of Things terminal with passive Internet of Things terminal reading capability, which has maintained access and has been registered in the network.

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