[0340] FIG. 1A is a schematic diagram of an architecture of a communication system according to an embodiment of the present disclosure.

[0341] As shown in FIG. 1A, the communication system 100 includes a first Ambient IoT device 101, an intermediate node 102, a core network 103, and an access network device 104.

[0342] In some embodiments, the first Ambient IoT device 101, for example, includes an Internet of Things (IoT) device. In the Ambient IoT scenario, the first Ambient IoT device 101 can include, but is not limited to, a device triggered by a reader to send data and / or signaling, which is installed with Radio Frequency Identification (RFID) and can perform inventory, data reporting, and other operations.

[0343] In some embodiments, the intermediate node 102 is located between the first Ambient IoT device 101 and the access network device 104.

[0346] In some embodiments, the core network 103 can be one device including one or more network elements, etc., or can be a plurality of devices or device groups. The network element can be virtual or physical. The core network includes, for example, at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next generation core (NGC).

[0347] In some embodiments, the core network 103 can include, but is not limited to, one or more core network functions. For example, in the embodiments of the present disclosure, the core network 103 can include, but is not limited to, a first core network function 103-1, a second core network function 103-2, a third core network function 103-3, and the like.

[0348] In some embodiments, the first core network function 103-1 in the present disclosure can be, for example, an access and mobility management function (AMF).

[0349] In some embodiments, the second core network function 103-2 can be a separately deployed function, which can be dedicated to serving the environmental Internet of Things device 101.

[0350] In some embodiments, the function supported by the second core network function 103-2 can also be deployed on the first core network function 103-1 without separate deployment, so as to directly reuse the existing core network architecture and be compatible.

[0351] In some embodiments, the third core network function 103-3 can be, for example, a network exposure function (NEF).

[0352] In some embodiments, the core network 103 can further include other functions, such as a user plane function (UPF), and the like, which will not be described herein.

[0353] In some embodiments, the access network device 104 can be, for example, at least one of a node or device that accesses a terminal to a wireless network, and can include at least one of an evolved node B (eNB) in a 5G communication system, a next generation eNB (ng-eNB), a next generation node B (gNB), a node B (NB), a home node B (HNB), a home evolved node B (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, an access node in a Wi-Fi system, but is not limited thereto.

[0354] In some embodiments, the above-mentioned access network device can be composed of a central unit (CU) and a distributed unit (DU), wherein the CU can also be referred to as a control unit (control unit), and the CU-DU structure can split the protocol layers of the access network device, and the functions of part of the protocol layers are controlled by the CU, and the functions of the remaining part or all of the protocol layers are distributed in the DU and controlled by the CU, but are not limited thereto.

[0355] In some embodiments, the technical solutions of the present disclosure can be applied to the Open RAN architecture, at which time the interfaces between or within the access network devices involved in the embodiments of the present disclosure can become internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be realized by software or programs.

[0356] In embodiments of the present disclosure, the environmental IoT device can include, but is not limited to, the following types:

[0357] Device terminated (DT) type, which can be triggered by the network side to end the traffic by the environmental IoT device;

[0358] Device-originated-device-terminated triggered (DO-DTT) type, which can be triggered by the device to start and end the traffic.

[0359] Among them, the environmental IoT device of the DO-DTT type can be triggered by the access network device or the intermediate node as the reader to send traffic, and the core network does not send traffic to it.

[0360] Among them, the research of the environmental IoT device of the device-originated-autonomous (DO-A) type can depend on the decision of the radio access network (RAN).

[0361] In some embodiments, the present disclosure provides two topologies.

[0362] For example, as shown in FIG. 1B, in topology 1, the environmental IoT device directly communicates with the access network device, such as the base station. The communication between the base station and the environmental IoT device includes environmental IoT data and / or signaling. This topology includes the possibility that the base station sends to the environmental IoT device is different from the base station received from the environmental IoT device.

[0363] For example, as shown in FIG. 1C, in topology 2, the environmental IoT device and the base station communicate through an intermediate node. In this topology, the intermediate node can be a relay, an IAB node, a terminal, etc. that can implement environmental IoT. The intermediate node transmits information between the base station and the environmental IoT device.

[0364] In some embodiments, the present disclosure provides a method for triggering operation, for example, as shown in FIG. 1D, including the following steps:

[0365] Step S1401, the AF sends an operation request to the AIoT controller (in the present disclosure, a plurality of core network functions can be collectively referred to as AIoT controller).

[0366] Among them, the AF can selectively include the following information:

[0367] -Filtering conditions, limiting operations to AIoT devices that meet these conditions;

[0368] - a reader identification list for limiting the operation to specific readers;

[0369] - periodic information for requesting the operation to be performed periodically.

[0370] In the above embodiment, the operation request in FIG. 1D can be an inventory request.

[0371] In step S1402, the AIoT controller verifies whether the AF is authorized to issue the received operation request.

[0372] For example, the AIoT controller verifies whether the AF is allowed to issue an inventory request with specified filtering conditions or without any filtering conditions without providing a reader identification, etc.

[0373] In step S1403, the AIoT controller sends the operation request, including the filtering conditions and the periodic information (if provided by the AF), to the reader corresponding to the reader identification or to all readers.

[0374] In step S1404, each reader receiving the operation request from the AIoT controller performs the operation according to the filtering conditions (if provided).

[0375] The reader either performs a one-off operation or performs a periodic operation according to the received periodic information.

[0376] In step S1405, one or more AIoT devices respond to the reader and provide AIoT device identifications.

[0377] In step S1406, the reader collects the received AIoT device identifications and provides the AIoT device identifications to the AIoT controller. The reader can also optionally include extended data.

[0378] In step S1407, for each reported AIoT device identification, the AIoT controller associates the reader identification reporting the AIoT device identification and a timestamp.

[0379] The timestamp enables the AIoT controller to clear out-of-date last known reader information. Details in this regard depend on the implementation of the AIoT controller.

[0380] In step S1408, the AIoT controller provides the AIoT device identifications and optional extended data to the AF.

[0381] In the above embodiment, the environment IoT device can be triggered by the core network to perform the corresponding operation.

[0382] The present disclosure also provides a communication method and device, and a storage medium, which can be triggered by an intermediate node to enable an environmental IoT device to perform a first operation, thereby improving the availability and reliability of the environmental IoT device.

[0383] FIG. 2A is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2A, the present embodiment relates to a communication method, which includes the following steps:

[0384] In step S2101, the intermediate node 102 sends a second message to the core network 103.

[0386] In some embodiments, the intermediate node 102 can be a terminal, an IAB node, a relay, etc., which is not limited in the present disclosure.

[0387] In some embodiments, the intermediate node 102 can be a reader of the first environmental IoT device 101.

[0388] In some embodiments, the second message can be used to request authorization for triggering the first operation.

[0389] In some embodiments, the first operation is an operation between the intermediate node 102 and a second environmental IoT device. The second environmental IoT device is the first environmental IoT device that the intermediate node 102 expects to perform the first operation.

[0390] In some embodiments, the first operation can include, but is not limited to, at least one of the following:

[0407] The third location can be a location of the intermediate node.

[0408] It can be understood that the second message can include the second location and / or the third location.

[0409] For example, in the case that the communication distance of the intermediate node 102 is limited, the third location of the intermediate node can be used to replace the second location of the second environmental IoT device, and in this case, the second message can only include the third location.

[0410] For another example, in the case that the intermediate node 102 pre-stores the second location of the second environmental IoT device, the second message can only include the second location.

[0411] For another example, in the case that the intermediate node 102 pre-stores the second location of the second environmental IoT device and the communication distance of the intermediate node 102 is limited, the second message can include the second location and the third location.

[0412] The second device information is information of the second environmental IoT device, including but not limited to an identifier of the second environmental IoT device, for example, an Electronic Product Code (EPC) of the second environmental IoT device, or can include a group identifier, for example, an identifier of a device group to which the second environmental IoT device belongs. Or can include a type of the second environmental IoT device, for example, type A, type B, or type 1, type 2, and the classification standard is not limited in the present disclosure.

[0413] The first request information can be used to request the core network 103 to provide the assistance information, and the intermediate node 103 can subsequently trigger the first operation based on the assistance information.

[0414] Exemplarily, the assistance information can include but is not limited to at least one of the following:

[0415] Information of the environmental IoT device that the intermediate node 102 is permitted to perform the first operation.

[0416] The information can include but is not limited to an identifier of the environmental IoT device, a group identifier, a device type, and the like.

[0417] The present disclosure does not limit the content of the assistance information, and any information that can assist the intermediate node 103 to trigger the first operation shall fall within the protection scope of the present disclosure.

[0418] The second environmental IoT device mentioned above refers to an environmental IoT device that the intermediate node 102 expects to trigger to perform the first operation.

[0419] In some embodiments, the core network 103 receives the second message.

[0420] In step S2102, the core network 103 determines an authorization result.

[0421] In some embodiments, the core network 103 can determine the authorization result based on a policy provided by a Policy Control Function (PCF), a local policy, a pre-configuration, and a terminal context, in combination with the information of the second environmental IoT device, and the like. The present disclosure does not limit the way of determining the authorization result.

[0422] The authorization result can indicate permission of the authorization, or rejection of the authorization.

[0423] In step S2103, the core network 103 sends a second response message to the intermediate node 102.

[0424] In some embodiments, the core network 103 sends the second response message to the intermediate node 102 through the access network device 104.

[0425] In some embodiments, the second response message can be a downlink non-access stratum transport message.

[0426] In some embodiments, the authorization result can be included in the second response message.

[0427] In some embodiments, the second response message can include the assistance information in a case that the authorization result indicates that the authorization is permitted by the core network.

[0428] In some embodiments, the second response message can include a rejection cause in a case that the authorization result indicates that the authorization is rejected by the core network.

[0429] In some embodiments, the steps S2101 to S2103 can not be performed. For example, the steps S2101 to S2103 can not be performed when the intermediate node 102 does not need to obtain the authorization, or the intermediate node 102 does not need the assistance information.

[0430] At step S2104, the intermediate node 102 sends a first message to one or more first environmental IoT devices.

[0431] In some embodiments, the first message is used to trigger a first operation.

[0432] In some embodiments, the intermediate node 102 can send the first message to the first environmental IoT devices based on the obtained assistance information.

[0433] In some embodiments, the intermediate node 102 can broadcast the first message.

[0721] In the above embodiment, the second core network function can provide authorization for the intermediate node and obtain the first operation result, thereby improving the availability and reliability of the environmental IoT device.

[0722] The above process is further illustrated as follows.

[0723] Embodiment 1, FIG. 4A is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 4A, the present embodiment relates to a communication method, taking the intermediate node as the UE, and taking the second core network function as the environmental IoT function (for example, AIoTF, the name is not limited) as an example, the above method comprises:

[0724] Step S4101, the UE decides to trigger the inventory / discovery process of the environmental IoT device, and the UE can send a request to the AMF or AIoTF to obtain permission to trigger the inventory / discovery procedure.

[0725] Among them, the UE can send an inventory / discovery request message to the AMF.

[0726] Among them, the message includes event type (for example, discovery, inventory, periodic inventory event, which can be single or multiple types), time information, location information and target environmental IoT device information (for example, group ID, device ID, device type), and can indicate a request to provide assistance information (for example, a list of candidate environmental IoT devices).

[0727] Step S4102, if the AIoTF is available, the AMF sends an inventory / discovery request including the above parameters to the AIoTF.

[0728] Step S4103, if step S4102 is executed, the AIoTF determines whether to allow the UE to perform the inventory / discovery process of the environmental IoT device.

[0729] Among them, the AIoTF can make a decision based on the policy from the PCF, or the AIoTF local policy, pre-configuration and UE context information (for example, UE capability for environmental IoT service) and target environmental IoT device information.

[0730] The AIoTF sends the result of the inventory / discovery request together with the assistance information (if the assistance information is requested), or the rejection reason to the AMF.

[0731] If the AIoTF accepts the request, the AIoTF can send an inventory request accept message to the AMF. The AIoTF can include the assistance information requested by the UE to the AMF. For example, the accept message can include the list of allowed / candidate environmental IoT devices that can be discovered / inventoried, and the device information (ID, group ID, device type).

[0732] If the AIoTF rejects the request, the AIoTF can send an inventory request reject message to the AMF (including the rejection reason).

[0733] Step S4104, if steps S4102-S4103 are performed, the AMF forwards the message from the AIoTF to the UE.

[0734] If steps S4102-S4103 are skipped, the AMF decides whether to accept the request from the UE and then sends an accept / reject message to the UE.

[0735] The AMF makes the decision based on the policy from the PCF, the AMF local policy, pre-configuration, and the UE context / information (e.g., UE capability for environmental IoT service) and the target environmental IoT device information.

[0736] The AMF sends the result of the inventory / discovery request to the UE, along with the assistance information (with / without request) and the rejection reason.

[0737] If the AMF accepts the request, the AMF can send an inventory request accept message to the UE. The AIoTF can include the assistance information requested by the UE to the AMF. For example, the accept message can include the list of allowed / candidate environmental IoT devices that can be discovered / inventoried, and the device information (ID, group ID, device type).

[0738] If the AMF rejects the request, the AMF can send an inventory request reject message to the UE (including the rejection reason).

[0739] Note: The UE can not need to request permission or not need the assistance information from the core network, steps S4101-S4104 can be skipped. If the AIoTF is not deployed in the network, steps S4102-S4103 can be skipped.

[0740] Step S4105, the UE sends an inventory / discovery command / request to the environmental IoT, including the event information, UE information, and target environmental IoT device information (e.g., environmental IoT device ID and / or group ID).

[0741] The UE can send the message based on the received assistance information. The UE can broadcast the message, or send the message to specific environmental IoT devices.

[0742] Step S4106, if step S4105 is performed, the environmental IoT device receives the message from the UE and responds to the UE with an inventory / discovery response / ACK.

[0743] Exemplarily, when the target environmental IoT information and / or event information matches, the device can respond, or the device can respond to each message, and the UE can filter the messages matching the information. The response message includes device information (device ID, group ID, device type), allowed / available event type list, allowed / available time, available location (or not allowed / unavailable time and location), and device capability.

[0744] If step S4105 is skipped, the environmental IoT device sends a manifest / discovery command / response to the UE or AMF.

[0745] The request message includes device information (device ID, group ID, device type), request / allowed / available event type list, allowed / available time, available location (or not allowed / unavailable time and location), and device capability.

[0746] Note: DOA type will skip step S4105, DO-DTT type can perform steps S4105 to S4106.

[0747] Note: The scheme of the present disclosure can correspond to topology 2.

[0748] Step S4107, the UE collects messages from the environmental IoT device, and can save and filter messages from the environmental IoT device (optional).

[0749] If step S4105 is performed, the UE can collect and filter messages from the environmental IoT device. The UE can save messages matching the assistance information.

[0750] If step S4105 is skipped, the UE can decide whether to accept the request from the environmental IoT device. If accepted, the UE can save the message from the environmental IoT device and send a request acceptance to the environmental IoT device. If rejected, the UE can send a rejection message with a reason to the environmental IoT device.

[0751] Step S4108, the UE sends the inventory / discovery result and environmental IoT information, event type, location information, and time information to the AMF. The UE can include the message via the UL NAS TRANSPORT message to the AMF.

[0752] Step S4109, the AMF can send the inventory result to the AIoTF.

[0753] The message includes environmental IoT device information, UE information, association of environmental IoT device event type, event information, allowed / available event type list, allowed / available time, available location (or disallowed / unavailable time and location), and device capability.

[0754] Step S4110, the AIoTF can send an ACK / response to the AMF to notify the confirmation of the inventory / discovery result.

[0755] Note: If the AIoTF is not deployed, steps S4109-S4110 can be skipped. If no response is needed, step S4110 can be skipped.

[0756] Step S4111, the AMF sends the inventory result to the NEF.

[0757] If needed, the NEF can map internal device information and standard ID to external device information and standard ID, which can include further interaction with the UDM.

[0758] Step S4112, the NEF provides the inventory result to the AF.

[0759] The NEF sends a service parameter notification message (Nnef_ServiceParameter_Notify) to the AF, including external device information and policy / standard ID, as well as inventory result and device information, UE information, and association of UE and device.

[0760] Embodiment 2, FIG. 4B is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 4B, embodiments of the present disclosure relate to a communication method, in which the intermediate node is a UE, the core network functions other than the AF are collectively referred to as an AIoT controller (AIoT Controller), and the first operation is a discarding operation, the above-mentioned method comprises:

[0761] Step S4201, the UE sends an inventory request to the AIoT controller.

[0762] Step S4202, the AIoT controller sends an inventory request acceptance / rejection to the UE.

[0763] Step S4203, the UE sends an inventory command to the AIoT device.

[0764] Step S4204, the AIoT device sends an inventory response / ACK to the UE.

[0765] Step S4205, the UE performs data collection.

[0766] Step S4206, the UE sends an inventory result to the AIoT controller.

[0767] In step S4207, the AIoT controller provides the inventory result to the AF.

[0768] The specific implementation process is not described here again.

[0771] It should be understood that the division of each unit or module in the above device is only a logical function division, and all or part of the units or modules can be integrated into one physical entity, or can be physically separated. In addition, the units or modules in the device can be implemented in the form of processor calling software: for example, the device includes a processor, the processor is connected with a memory, the memory stores instructions, and the processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of each unit or module of the above device, wherein the processor is, for example, a general processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory in the device or a memory outside the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuit, and the functions of part or all of the units or modules can be implemented by designing the hardware circuit, and the hardware circuit can be understood as one or more processors; for example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC), and the functions of part or all of the units or modules are implemented by designing the logical relationship of elements in the circuit; for example, in another implementation, the hardware circuit is a programmable logic device (PLD), and a field programmable gate array (FPGA) is taken as an example, which can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by a configuration file, so as to implement the functions of part or all of the units or modules.

In one implementation, the processor can be a circuit with instruction reading and running capability, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), a digital signal processor (DSP), or the like. In another implementation, the processor can implement certain functions through a logical relationship of a hardware circuit, and the logical relationship of the hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In the reconfigurable hardware circuit, the processor loads a configuration document to implement the configuration of the hardware circuit.
