Next, each step of the data interaction method of the passive internet of things will be described in detail.

In an exemplary embodiment of the present disclosure, as shown in fig. 3, reading service data of the passive internet of things terminal according to the device information and the service request includes:

Step S302, receiving the service request sent by the access and mobility management function network element, determining a corresponding passive Internet of things terminal according to the equipment information, and reading the service data from the passive Internet of things terminal corresponding to the service request.

In an exemplary embodiment of the present disclosure, as shown in fig. 4, the data interaction method of the passive internet of things further includes:

Step S402, after the selected instruction is configured to trigger the service of the passive internet of things terminal, the access and mobility management function network element selects or discovers and determines a terminal reader according to the requirement information of the service of the passive internet of things terminal.

In an exemplary embodiment of the present disclosure, as shown in fig. 5, a data interaction architecture 500 of a passive internet of things includes Ambient IoT Reading (passive internet of things terminal read-write), AMF/AIoTMF (access and mobility management function network element), base Station (RAN) (Base Station), SMF (session management function network element), NEF (network open function network element), AF (passive internet of things application function network element), and the like, but is not limited thereto, wherein Ambient IoT Reading includes Ambient IoT UE Reader (passive internet of things terminal read-write) and AIoT (passive internet of things terminal), and specific functions of each component in the data interaction architecture 500 of a passive internet of things include:

Passive internet of things read-write terminal Ambient IoT UE Reader: the main function of the 3GPP UE terminal capable of performing corresponding read-write operation on the information stored in the AIoT terminal is to read the information in the AIoT memory, transmit AIoT related data to the network, request the network to provide AIoT related service, and the reader can perform write operation on AIoT after obtaining authorization of the network and the service provider (AIoT Service provider).

Passive internet of things terminal (Ambient IoT, abbreviated AIoT): according to the definition of the Ambient IoT by 3GPP, the Ambient IoT is an IoT device with very low energy storage, very low power consumption, not equipped with a SIM card, and is classified into a weak terminal supporting only backscatter communication (Backscatter Communication) and a strong terminal supporting self-generated signals or using backscatter communication, depending on whether an amplifier is equipped or not.

Access and mobility management functions: the passive internet of things management function is mainly responsible for collecting and managing the data of AIoT terminals, managing the state and other information of AIoT at the same time, and performing related management and cooperation on the base station with the AIoT terminal read-write capability and the 3GPP UE. AIoTMF can send control signaling and transmission data to Ambient IoT UE Reader and AIoT.

Passive internet of things application function: the AF, in the system of the present disclosure, refers to the third party service responsible AIoT for the correlation, may send AIoT the correlation information to the network and request the network to perform AIoT the correlation service.

In one exemplary embodiment of the present disclosure, if the device owner of AIoT is a network operator, the AF would typically be deployed within the core network, i.e., AMF/AIoTMF may communicate directly with the AF without having to go through the NEF.

In one exemplary embodiment of the present disclosure, if the device owner of AIoT is a third party vendor, then the AF would typically be after the N6 port and AMF/AIoTMF would need to be forwarded through the NEF while transmitting AIoT data.

In an exemplary embodiment of the present disclosure, as shown in fig. 6, a service triggering manner of a data interaction scheme of a passive internet of things includes AF triggering and AMF/AIoTMF autonomous triggering, and an interaction process of the two triggering manners includes:

AMF/AIoTMF autonomous triggering (Self-TRIGGERED): i.e., AMF/AIoTMF (access and mobility management function network element) 602 responds to AIoT terminal data collection service or AIoT terminal management service according to its own stored configuration information, i.e., "AMF/AIoTMF Triggers Ambient IoT Data collection".

In an exemplary embodiment of the present disclosure, the generating process of the configuration information includes: typically, when the registration request or the service request is sent AIoT by the owner AIoTMF of the AIoT terminal, the service information AIoT is sent together with the AIoT device information, and the owner of the AIoT terminal may be the operator or the third party device.

In an exemplary embodiment of the present disclosure, AIoTMF generates corresponding configuration information according to AIoT device information and service information, and stores the generated configuration information in AIoTMF.

In an exemplary embodiment of the present disclosure, the service of the passive internet of things terminal is usually a regular or periodic service, and AIoTMF may trigger AIoT the service of data collection or management according to the time node of the actual configuration information.

AF trigger (AF TRIGGERED): the AF (passive internet of things application function network element) 606 sends AIoT a related service request, i.e. "AF Requests collecting Ambient IoT Data", to the NEF (network open function network element) 604 according to the actual service needs.

Further, NEF604 discovers and selects the corresponding AMF/AIoTMF602 and forwards the Request for AF606 thereto, i.e., "NEF Discover/SELECT AMF/AIoTMF AND SEND AF Request".

The AMF/AIoTMF602, after receiving the related service request, requests the corresponding UE Reader and AIoT to execute the service according to the actual request content.

In an exemplary embodiment of the present disclosure, as shown in fig. 7, a service execution process of a data interaction scheme of a passive internet of things includes:

In one exemplary embodiment of the present disclosure, discovery and selection of UE Reader: after triggering the related service of the mobile IoT (passive internet of things terminal) 702, the AMF/Ambient IoTMF (access and mobility management function network element 7) 706 discovers and selects the UE Reader according to the actual service requirement, namely "AMF/AIoTMF Discover/Select AIoT UE Reader(s)".

In an exemplary embodiment of the present disclosure, in case of autonomous triggering of the AMF/Ambient IoTMF706, the Ambient IoTMF may directly select the corresponding terminal 704 (terminal Reader/writer) to perform the service, since the information of the corresponding UE Reader is typically already stored Ambient IoTMF at the time of the configuration phase.

In an exemplary embodiment of the present disclosure, in the case of an AF (passive internet of things application function network element) 710 trigger, the AMF/Ambient IoTMF706 generally needs to discover the UE Reader first, and then send a service execution request to the UE Reader corresponding to the requested Ambient IoT702 after confirming it.

In one exemplary embodiment of the present disclosure, AMF/Ambient IoTMF706 sends a data collection request: ambient IoTMF after selecting the corresponding UE Reader, a NAS layer connection is established with the UE Reader, and an Ambient IoT 702-related service request and an Ambient IoT702 device-related information are sent to the UE Reader in NAS MESSAGE, where the service request is typically a data collection request, i.e. "AMF/AIoTMF send AIoT Data Collection Request (NAS MESSAGE)".

In one exemplary embodiment of the present disclosure, the UE Reader reads the Ambient IoT702 terminal data: after receiving Ambient IoTMF service request, UE Reader performs data reading service on the requested mobile IoT702 terminal, and collects mobile IoT702 related data required by the service, namely "UE Reader collect AIoT Data".

In one exemplary embodiment of the present disclosure, the UE Reader data reporting: after the UE Reader collects the data of the Ambient IoT702, the UE Reader uploads the relevant data of the Ambient IoT702, i.e. "UE Reader upload AIoT Data (NAS MESSAGE)", in the form of NAS MESSAGE to Ambient IoTMF.

In one exemplary embodiment of the present disclosure, the data reporting process includes: ambient IoTMF after all the Ambient IoT702 data of the service request is collected, the requested Ambient IoT702 data, i.e. "AMF/AIoTMF upload AIoT Data", is returned to the AF710 via the SMF (session management function network element) 708.

Corresponding to the above embodiment, the present disclosure further provides a data interaction device of the passive internet of things, which may be used to execute the above method embodiment.

Fig. 8 is a block diagram of a data interaction device of a passive internet of things in an exemplary embodiment of the present disclosure.

Referring to fig. 8, a data interaction device 800 of the passive internet of things may include:

The interaction module 802 is configured to establish NAS layer connection with an access and mobility management function network element in response to a selected instruction of the access and mobility management function network element, and receive a service request of a passive internet of things terminal and device information of the passive internet of things terminal sent in a form of NAS MESSAGE, where the form of NAS MESSAGE is a form of performing data interaction based on the NAS layer.

The interaction module 802 is further configured to read service data of the passive internet of things terminal according to the device information and the service request.

The interaction module 802 is further configured to report the service data to the access and mobility management function network element in the form of NAS MESSAGE, so that the access and mobility management function network element feeds back the service data to the passive internet of things application function network element that initiates the service request through the network open function network element.

In an exemplary embodiment of the present disclosure, the interaction module 802 is further configured to:

After the selected instruction is configured to trigger the service of the passive internet of things terminal, the access and mobility management function network element selects or discovers and determines the UE reader according to the requirement information of the service of the passive internet of things terminal.

Since the functions of the apparatus 800 are described in detail in the corresponding method embodiments, the disclosure is not repeated herein.

In summary, the data interaction scheme of the passive internet of things provided by the present disclosure at least achieves the following effects:

(1) The present disclosure is based on enhancing the N1 port of the existing 3GPP, i.e., NAS layer protocol, so that the core network side AMF can communicate with the UE Reader and transmit AIoT related control signals and data.

(2) The present disclosure is based on AMF enhancement AIoTMF function, so that the AMF has functions of relevant service management and data collection and management for AIoT, and in particular, the AMF can request the UE Reader to execute relevant AIoT service through NAS layer protocol, transmit control request and transmit AIoT relevant data and information.

(3) The service scenario faced by the present disclosure is a scenario in which the UE Reader performs read-write and other service operations on AIoT, and the present disclosure has considered the scenario in which the gcb Reader is read-written to the base station as far as possible in the design, but the actual situation and influence of the scenario are not within the scope of the present disclosure.

(4) The enhancement of the relevant NAS layer protocol is to transmit in NAS MESSAGE form, i.e. the control request for AIoT and UE Reader and the relevant data of AIoT are transmitted in NAS MESSAGE form on the N1 port, i.e. NAS layer.

(5) The present disclosure also classifies the actual triggering of a service into two modes, namely self-triggering and AF triggering, considering different requesters of the service and the execution mode of the actual service in the future and the owners of the devices (i.e., AIoT devices issued by operators and AIoT devices issued by third party vendors).
