For example, the AF information may inform the A-IoT device of the AF that issued the instruction to cancel the periodic operation, thereby facilitating more efficient cancellation of the A-IoT device's periodic operation. The A-IoT device information may indicate the A-IoT device or group of A-IoT devices for which the periodic operation is to be canceled, thereby facilitating quick and targeted cancellation of the periodic operation of a specific A-IoT device or group of A-IoT devices. The A-IoT device location information may indicate the location of the A-IoT device for which the periodic operation is to be canceled, thereby facilitating quick and targeted cancellation of the A-IoT device at that location, or of at least one A-IoT device within that location. The time information for canceling the periodic operation of the A-IoT device may indicate a specific moment or time period for cancellation of the periodic operation, thereby facilitating more flexible and accurate cancellation of the periodic operation.

[0169] A-IoT devices are IoT devices powered by energy harvesting technology, and their energy storage capabilities are relatively limited.

[0170] The transmission types of A-IoT devices generally include: device-terminated (DT), device-originated-device-terminated triggered (DO-DTT), and device-originated–autonomous (DO-A).

[0171] In some embodiments, DO-DTT is triggered by an access network device or terminal as a reader, while the core network device (CN) does not trigger the A-IoT device.

[0172] In some embodiments, the connectivity topologies related to A-IoT devices generally include two examples as shown in FIG. 1a and FIG. 1b .

[0173] FIG1a is a schematic diagram of a connection topology associated with an A-IoT device according to an embodiment of the present disclosure. As shown in FIG1a , in this topology, the A-IoT device directly engages in bidirectional communication with a base station (BS). The communication between the base station and the A-IoT device includes ambient IoT data and / or signaling. This topology includes the possibility that the information sent by the BS to the A-IoT device may be different from the information received by the BS from the A-IoT device.

[0174] Figure 1b is a schematic diagram of the connection topology structure related to the A-IoT device shown in accordance with an embodiment of the present disclosure. As shown in Figure 1b, in this topology, the A-IoT device is connected to the intermediate node, and the two communicate uplink or downlink. The intermediate node is connected to the A-IoT device, and the two communicate uplink or downlink. The base station and the A-IoT device do not directly communicate uplink or downlink. Among them, the base station and the A-IoT device can be connected through a user unit (Uu) interface. Among them, the intermediate node can be, for example, a relay device, an integrated access and backhaul node (IAB Node), a UE or a repeater, and other devices with A-IoT capabilities.

[0175] It should be noted that for ease of understanding, the relevant terms in the following embodiments need to be explained, including, for example:

[0176] "Inventory taking": In IoT systems, this process is typically accomplished through sensors, radio frequency identification (RFID) technology, or other wireless communication technologies. These technologies can help automatically identify and track items, thereby improving the accuracy and efficiency of inventory taking. The purpose of inventory taking is to ensure that recorded inventory levels match actual inventory and to promptly identify missing, damaged, or excess items (including, for example, IoT devices). In some embodiments, "inventory taking" may also be referred to as "inventory taking."

[0177] "Inventory": In an IoT system, inventory refers to the IoT devices that exist in the system.

[0178] Figure 1c is a schematic diagram of an inventory procedure for an A-IoT device according to an embodiment of the present disclosure. As shown in Figure 1c, an inventory procedure for an A-IoT device is disclosed, including the following steps.

[0179] In step S1101, an application function (AF) sends an inventory request to an ambient internet of things controller (A-IoT Controller).

[0180] In some embodiments, the inventory request sent by the AF to the A-IoT Controller may include at least one of the following items 1) to 3):

[0181] 1) Use filter criteria to limit inventory so that the A-IoT devices in the inventory meet the policy's restriction requirements;

[0182] 2) Reader identification (ID), which is used to limit the A-IoT devices in the inventory by the reader ID;

[0183] 3) Cycle value, used to request periodic inventory counts based on the cycle value.

[0184] In step S1102 , the A-IoT Controller authorizes the AF's request.

[0185] In some embodiments, after receiving a request from the AF (i.e., an inventory request), the A-IoT Controller verifies whether the AF has the authority to issue the request based on the request. For example, when processing an inventory request, the A-IoT Controller checks whether the AF has the authority to send the inventory request based on a specific policy or without any filtering policy (and without providing a reader ID).

[0186] In step S1103 , the A-IoT Controller sends an inventory request to the reader.

[0187] In some embodiments, the A-IoT Controller sends an inventory request (an authorized inventory request sent by the AF) to the corresponding reader based on the reader's ID, which includes content such as a screening policy and periodicity information.

[0188] In step S1104 , the reader sends an inventory request to the A-IoT device.

[0189] In some embodiments, the reader executes an inventory procedure based on a filter policy in an inventory request received from the A-IoT Controller. For example, if the filter policy includes a periodic value, the reader may perform an inventory count periodically or perform a one-time inventory count.

[0190] In step S1105 , the A-IoT device sends an inventory response to the reader.

[0191] In some embodiments, one or more A-IoT devices respond to the inventory request sent by the reader and issue a corresponding inventory result, i.e., an inventory response, wherein the inventory response includes, for example, the ID of the A-IoT device.

[0192] In step S1106 , the reader sends an inventory response to the A-IoT Controller.

[0193] In some embodiments, the reader obtains the inventory response (including, for example, the ID of the A-IoT device) and sends the inventory response to the A-IoT Controller.

[0194] Optionally, the reader may selectively send additional relevant information, such as the reader's ID and / or the A-IoT device's ID, to the A-IoT Controller along with the inventory result in the inventory response.

[0195] In step S1107 , the A-IoT Controller stores the inventory response.

[0196] In some embodiments, for inventory responses reported by readers (including, for example, the A-IoT device ID mentioned in the inventory response), the A-IoT Controller stores the reader ID that reported the inventory response along with the corresponding timestamp. The timestamp enables the A-IoT Controller to purge outdated last-known reader information (ensuring the timeliness of inventory response reports).

[0197] In step S1108 , the A-IoT Controller sends an inventory response to the AF.

[0198] In some embodiments, the A-IoT Controller sends an inventory response to the AF.

[0199] Optionally, the reader can selectively send additional relevant information to the A-IoT Controller along with the inventory result in the inventory response, such as the reader's ID and / or the A-IoT device's ID, enriched data, etc.

[0200] Since the energy storage capacity of A-IoT devices is limited, how to reduce the energy consumption of A-IoT devices is a topic under research.

[0201] Therefore, the present disclosure provides a communication method, which sends first information to the first network element through the AF to instruct the cancellation of the periodic operation of the A-IoT device, thereby effectively reducing the energy consumption of the A-IoT device.

In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0210] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit.

[0215] FIG2a is a schematic diagram illustrating an interaction of a communication method according to an embodiment of the present disclosure. As shown in FIG2a , the present disclosure embodiment relates to a communication method for use in a communication system 100, the method comprising:

[0216] The terminal 105 and the third network element 104 in FIG. 2 a are optional, and the dotted boxes of the terminal 105 and the third network element 104 indicate that the terminal 105 and the third network element 104 are optional.

[0217] Step S2101 , AF101 sends first information to the first network element 102 .

[0218] In some embodiments, the first network element 102 receives the first information sent by AF101.

[0219] In some embodiments, the first information is used to instruct the cancellation of a periodic operation of an A-IoT device. For example, the periodic operations of an A-IoT device include periodic inventory taking, periodic reporting of inventory results, and periodic reporting of events. The first information may be used to instruct the cancellation of at least one of these operations. For example, the first information may be used to instruct the A-IoT device to cancel the periodic inventory taking operation. In another example, the first information may be used to instruct the A-IoT device to cancel the periodic reporting of events. In another example, the first information may be used to instruct the A-IoT device to cancel both the periodic inventory taking operation and the periodic reporting of events. This disclosure is not intended to be exhaustive, but is not limited to these. For example, an event may include the operating status of an A-IoT device, which may include whether the A-IoT device is powered on. In another example, an event may include an environmental monitoring event, which may include monitoring data such as temperature, humidity, and air pressure. In another example, an event may include an alarm event, which may be triggered when an abnormality occurs in the device or environment. The above examples of periodic operations and events are merely illustrative, and this disclosure is not limited thereto.

[0220] In some embodiments, AF101 may be, for example, an AF, and first network element 102 may be, for example, an NEF. AF101 sends the first information to first network element 102 so that first network element 102 can subsequently send the first information to other network elements or devices to instruct the A-IoT device or a terminal associated with the A-IoT device to cancel the periodic operation of the A-IoT device.

[0221] In some embodiments, the first information includes at least one of the following: information of the AF; information of the A-IoT device; terminal information associated with the A-IoT device; information about the location of the A-IoT device; time information when the A-IoT device cancels the periodic operation; content information of the periodic operation; and information related to canceling the periodic operation.

[0222] Optionally, the first information may include information of the AF. For example, the first information may include an ID of the AF, so that when the A-IoT device or a terminal associated with the A-IoT device receives the first information, it can determine which network element sent the first information.

[0223] Optionally, the first information may include information about the A-IoT device. For example, the first information may include the ID of the A-IoT device for which the periodic operation needs to be canceled, the group ID of the group to which the A-IoT device belongs, and the like. The ID of the A-IoT device and the group ID of the group to which the A-IoT device belongs may be external IDs. External IDs can be understood as data originating from outside the communication system.

[0224] Optionally, the first information may include terminal information associated with the A-IoT device. The terminal associated with the A-IoT device can cancel periodic operations on the A-IoT device, that is, the terminal can cancel the periodic operations of its associated A-IoT device. Therefore, the first information may include terminal information associated with the A-IoT device, for example, the ID of the terminal associated with the A-IoT device, so that the first information can be sent to the terminal based on the terminal ID, and the terminal can cancel the periodic operations of the A-IoT device.

[0225] Optionally, the first information may include information about the location of the A-IoT device. The location of the A-IoT device may be a specific location or an area. For example, the periodic operation of the A-IoT device at that location may be canceled based on the first information, or the periodic operation of all A-IoT devices within the location area may be canceled based on the first information, or the periodic operation of a specific A-IoT device within the location area may be canceled based on the first information.

[0226] Optionally, the first information may include time information for canceling the periodic operation by the A-IoT device. For example, the time information may include a specific time period, such as a time period each day during which the periodic operation can be canceled. Another example is a specific moment, such as a time from which the periodic operation can be canceled.

[0227] Optionally, the first information may include content information of periodic operations. For example, periodic operations include periodic inventory, periodic reporting of inventory results, periodic reporting of events, etc., which have been introduced in the above embodiments and will not be repeated in this disclosure.

[0228] Optionally, the first information may include information related to canceling the periodic operation. For example, the information related to canceling the periodic operation may indicate canceling the periodic operation.

[0229] In some embodiments, the information related to canceling the periodic operation may include application layer information related to canceling the periodic operation.

[0230] In some embodiments, the information related to canceling the periodic operation may also include non-application layer information related to canceling the periodic operation.

[0231] In some embodiments, the first network element 102 may be, for example, a NEF, that is, the AF may send the first information to the NEF, but is not limited thereto.

[0232] In some embodiments, the name of the first information is not limited, and it can be, for example, "instruction information", "configuration information", etc.

[0233] Step S2102 : The first network element 102 sends first information to the second network element 103 .

[0234] In some embodiments, the second network element 103 receives the first information sent by the first network element 102 .

[0235] In some embodiments, the first network element may send external information corresponding to the first information to the second network element, or may map the external information corresponding to the first information to obtain internal information corresponding to the first information, and send the internal information corresponding to the first information to the second network element.

[0236] In some embodiments, the first network element maps the external information corresponding to the first information to obtain the internal information of the first information. For example, after authorizing the AF's request, the first network element may retrieve the internal information corresponding to the first information from the unified data management (UDM). For example, the UDM may retrieve the internal A-IoT device ID corresponding to the external A-IoT device ID, the internal A-IoT device group ID corresponding to the external A-IoT device group ID, the internal terminal ID associated with the A-IoT device corresponding to the external terminal ID associated with the A-IoT device, the internal time information corresponding to the external time information, the internal location information corresponding to the external location information, the internal event information corresponding to the external event information, and the internal application layer information corresponding to the external application layer information. The external information may be understood as information from outside the communication system. The internal information may be understood as information transmitted within the communication system. In some embodiments, the first network element 102 may be, for example, an NEF, and the second network element 103 may be, for example, an AMF. That is, the NEF may send the first information to the AMF, but this is not limited to this.

[0237] In step S2103 , the second network element 103 sends the first information to the terminal 105 or the A-IoT device 106 .

[0238] In some embodiments, the terminal 105 or the A-IoT device 106 receives the first information sent by the second network element 103.

[0239] In some embodiments, the second network element 103 may send the first information to the terminal or A-IoT device via a radio access network (RAN). That is, the RAN may transparently transmit the first information.

[0240] In some embodiments, the second network element 103 may send the first information to the terminal, and the terminal may act as an intermediate node between the second network element and the A-IoT device, sending the first information to the A-IoT device so that the A-IoT device cancels the periodic operation. Alternatively, the second network element 103 may send the first information directly to the A-IoT device so that the A-IoT device cancels the periodic operation. Alternatively, the second network element may send the first information to the terminal, and the terminal cancels the periodic operation of the A-IoT device. For example, the terminal may cancel the periodic operation of the A-IoT device associated with it, or the terminal may cancel the periodic operation of the A-IoT device indicated by the first information.

[0241] In some embodiments, the second network element 103 may be, for example, an AMF, that is, the AMF may send the first information to the terminal or the A-IoT device, but is not limited thereto.

[0242] It can be understood that the solid line step S2103 and the dotted line step S2103 in Figure 2a are in an OR relationship, that is, they are optional and have no primary or secondary relationship. The execution of the solid line step S2103 or the dotted line step S2103 can be selected according to the actual situation. When the dotted line step S2103 is executed, the terminal 105 can send the first information to the A-IoT device 106, or cancel the periodic operation of the A-IoT device based on the first information.

[0243] In step S2104 , the terminal 105 or the A-IoT device 106 cancels the periodic operation of the A-IoT device based on the first information.

[0244] In some embodiments, after receiving the first information, the terminal 105 may cancel the periodic operation indicated by the first information. For example, the terminal may cancel the periodic operation of its associated A-IoT device, or may cancel the periodic operation of the A-IoT device identified by the ID of the A-IoT device included in the first information, or may cancel the periodic operation of the A-IoT device at the location information based on the location information included in the first information. Examples are not given one by one in this disclosure.

[0245] In some embodiments, the A-IoT device may cancel the periodic operation indicated by the first information based on the first information. For example, the A-IoT device may cancel its own periodic operation. For another example, the A-IoT device may cancel its own periodic operation at a corresponding time period or time based on the time information included in the first information.

[0246] In some embodiments, after canceling the periodic operation indicated by the first information, the terminal 105 or the A-IoT device 106 obtains a result. For example, the result may include a successful cancellation of the periodic operation or a failure to cancel the periodic operation. For another example, when the result includes a failure to cancel the periodic operation, the result may also include a reason for the failure to cancel the periodic operation.

[0247] It is understood that the solid line step S2104 and the dashed line step S2104 in FIG2a are in an OR relationship, that is, they are optional and do not have a primary or secondary relationship. Depending on the actual situation, either the solid line step S2104 or the dashed line step S2104 can be executed. When the solid line step S2104 is executed, the A-IoT device 106 can subsequently send the second message. If the dashed line step S2104 is executed, the terminal subsequently sends the second message.

[0248] In step S2105 , the terminal 105 or the A-IoT device 106 sends second information to the second network element 103 .

[0249] In some embodiments, the second network element 103 receives the second information sent by the terminal 105 or the A-IoT device 106. In some embodiments, the second information is response information to the first information, that is, response information to cancel the periodic operation.

[0250] In some embodiments, the second information includes at least one of the following: information of the A-IoT device for canceling the periodic operation; information of the terminal associated with the A-IoT device for canceling the periodic operation; information of the association between the A-IoT device for canceling the periodic operation and the terminal; information of the result of canceling the periodic operation; and information of the reason for the failure to cancel the periodic operation.

[0251] Optionally, the second information may include information about the A-IoT device that canceled the periodic operation. For example, it may include the ID of the A-IoT device that canceled the periodic operation. That is, after canceling the periodic operation of the A-IoT device, the terminal or A-IoT device may report which A-IoT device or devices have had their periodic operation canceled, or may report information about the A-IoT device that successfully canceled the periodic operation and information about the A-IoT device that failed to cancel the periodic operation. That is, the A-IoT device that canceled the periodic operation indicated by the first information and the A-IoT device that actually successfully canceled the periodic operation may be the same or different. For example, if the first information indicates that the A-IoT devices that canceled the periodic operation are A and B, and A successfully canceled the periodic operation, while B failed to cancel the periodic operation, the terminal or A-IoT device may report A's ID to indicate that the A-IoT device that canceled the periodic operation is A. Alternatively, the terminal or A-IoT device may also report A and B separately, and indicate that A successfully canceled the periodic operation and B failed to cancel the periodic operation.

[0252] Optionally, the second information may include information about the terminal that cancels the association of the periodically operated A-IoT device. For example, the second information may include the ID of the terminal that cancels the association of the periodically operated A-IoT device. For example, if the association relationship between the A-IoT device and the terminal is known, then the second information may include the ID of the terminal that cancels the association of the periodically operated A-IoT device.

[0253] Optionally, the second information may include canceling the association between the periodically operated A-IoT device and the terminal. For example, the association between the A-IoT device and the terminal is unknown to the AF. That is, if there is no association between the terminal canceling the A-IoT device and the A-IoT device, the association between the terminal and the A-IoT device may be included in the second information after the A-IoT device is canceled to inform the AF.

[0254] Optionally, the second information may include result information of canceling the periodic operation. For example, the second information may include that the periodic operation is successfully canceled, or may include that the periodic operation is failed.

[0255] Optionally, if the cancellation of the periodic operation fails, the second information may include reason information of the failure to cancel the periodic operation, and subsequently informs the AF of the reason for the failure to cancel the periodic operation.

[0256] In some embodiments, the terminal 105 may cancel the periodic operation of the A-IoT device based on the first information and then send the second information to the second network element.

[0257] In some embodiments, the A-IoT device 106 may cancel the periodic operation of the A-IoT device based on the first information and then send the second information to the second network element. Alternatively, the A-IoT device 106 may cancel the periodic operation of the A-IoT device based on the first information and then send the second information to the terminal, which then sends the second information to the second network element.

[0258] In some embodiments, the terminal or A-IoT device may send the second information to the second network element via the RAN. That is, the RAN may transparently transmit the second information.

[0259] In some embodiments, the second network element 103 may be, for example, an AMF, that is, the terminal or A-IoT device may send the second information to the AMF, but is not limited thereto.

[0260] In some embodiments, the name of the second information is not limited, and it can be, for example, "response information", "report information", etc.

[0261] It can be understood that the solid line step S2105 and the dotted line step S2105 in Figure 2a are in an "or" relationship, that is, they are optional and do not have a primary-secondary relationship. You can choose to execute the solid line step S2105 or the dotted line step S2105 according to the actual situation. If the dotted line step S2105 is executed, the terminal may cancel the periodic operation of the A-IoT device and send the second information. Alternatively, the A-IoT device may cancel the periodic operation of the A-IoT device and send the second information to the terminal, and the terminal may send the second information in the dotted line step S2105.

[0262] Step S2106 , the second network element 103 sends second information to the first network element 102 or the third network element 104 .

[0263] In some embodiments, the first network element 102 or the third network element 104 receives the second information sent by the second network element 103. For example, the first network element 101 may receive the second information and send the first information to the AF. For another example, the third network element 104 may receive the second information and send the second information to the first network element 102, which then sends the first information to the AF.

[0264] In some embodiments, the first network element 102 may be, for example, an NEF, the second network element 103 may be, for example, an AMF, and the third network element 104 may be an A-IoTF. That is, the AMF may send the second information to the NEF or the A-IoTF, but is not limited thereto.

[0265] It can be understood that the solid line step S2106 and the dotted line step S2106 in FIG2a are in an OR relationship, that is, they are optional and have no primary or secondary relationship. Either the solid line step S2106 or the dotted line step S2106 can be selected for execution based on actual circumstances. If the dotted line step S2106 is executed, the third network element 104 can subsequently send the second information to the first network element 102, that is, execute step S2106.

[0266] Step S2107 , the third network element 104 sends second information to the first network element 102 .

[0267] In some embodiments, the first network element 102 receives second information sent by the third network element 104 .

[0268] Step S2107 is optional. For example, when the second network element 103 sends the second information to the third network element 104 in step S2106, step S2107 may be continued to send the second information to the first network element 102. For another example, when the second network element 103 sends the second information to the first network element 102 in step S2106, step S2107 may be omitted.

[0269] In some embodiments, the first network element 102 may be, for example, an NEF, and the third network element 104 may be an A-IoTF. That is, the A-IoTF may send the second information to the NEF, but is not limited thereto.

[0270] Step S2108: The first network element 102 sends the second information to the AF 101.

[0271] In some embodiments, AF101 receives second information sent by the first network element 102.

[0272] In some embodiments, the first network element 102 may send internal information corresponding to the second information to the AF 101 .

[0273] In some embodiments, the first network element 102 may map the internal information corresponding to the second information to obtain the external information corresponding to the second information, and send the external information corresponding to the second information to the AF 101 .

[0274] In some embodiments, the first network element 102 may map the internal information corresponding to the second information to obtain the external information corresponding to the second information. For example, the first network element 102 may retrieve the external information corresponding to the second information from the UDM.

[0275] In some embodiments, the first network element 102 may be, for example, a NEF, that is, the NEF may send the second information to the AF, but is not limited thereto.

[0276] The communication method involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2108. Each of steps S2101 to S2108 can be implemented as a separate embodiment. The embodiments can be combined in any manner and implemented in a different order, provided they are not in conflict. For example, step S2101 can be implemented as a standalone embodiment, but is not limited thereto.

[0277] In some embodiments, steps S2102 to S2108 are optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, step S2107 is optional.

[0486] For ease of understanding, the present disclosure provides the following two specific embodiments:

[0487] FIG10 is a schematic diagram showing an interaction of a communication method according to an embodiment of the present disclosure.

[0488] In step SX101, the AF sends a message to the NEF to cancel the periodic operation.

[0489] In some embodiments, the AF decides to cancel a periodic operation and sends a message to the NEF to cancel the periodic operation. Canceling the periodic operation may include canceling the periodic inventory procedure and / or unsubscribing from periodic inventory notifications. The message canceling the periodic inventory procedure may be the first message in the above embodiment.

[0490] In some embodiments, the AF can send an event reporting unsubscription message (Nnef_EventExposure_Unsubscribe) to unsubscribe from the periodic inventory. This message may include device information (e.g., the ID of the A-IoT device, the ID of the UE, the group ID, which may be an external ID), location information (which may be limited to a specific area), time information (which may be limited to a specific time), event information (related to the periodic inventory event, such as the event ID, used to notify the NEF to unsubscribe from the periodic inventory event), and a periodic inventory cancellation message (e.g., an application layer message).

[0491] In some embodiments, the device information may be the information of the A-IoT device in the above-mentioned embodiments, as well as the information of the terminal associated with the A-IoT device. The event information may be the content information of canceling a periodic operation in the above-mentioned embodiments. The cancel periodic inventory message may be a message related to canceling a periodic operation.

[0492] In some embodiments, the periodic inventory process may be triggered by the network, the UE (if any), or the A-IoT device.

[0493] In step SX102 , the NEF maps the external information into internal information.

[0494] In some embodiments, the NEF authorizes requests from the AF and maps external information to internal information. External information may include, for example, external device information, external location information, external time information, and external event information. Internal information may include, for example, internal device information, internal location information, internal time information, internal event information, and an internal cancel period inventory message.

[0495] In some embodiments, the cancel periodic inventory message may come from the application layer.

[0496] In some embodiments, step SX102 is optional.

[0497] In some embodiments, the NEF may also obtain internal information by retrieving the UDM.

[0498] In step SX103a-1, NEF sends information to AMF to cancel the periodic operation.

[0499] In some embodiments, for example, the NEF may call the AMF service to cancel the periodic inventory procedure or unsubscribe from the periodic inventory notification. The information may include device information, location information, time information, event information (if step 2 is performed, the information is mapped internal information) and cancellation of the periodic inventory information.

[0500] In step SX103a-2, AMF sends information to A-IoTF to cancel the periodic operation.

[0501] In some embodiments, if A-IoTF is available, the AMF sends a message to the A-IoTF to cancel the periodic operation. The A-IoTF is a network function (NF) dedicated to the A-IoT device.

[0502] In some embodiments, the AMF may invoke the A-IoTF service to cancel the periodic inventory procedure or unsubscribe from periodic inventory notifications. This message may include device information, location information, time information, event information, and a periodic operation cancellation message. It will be understood that if step SX102 is executed, the device information, location information, time information, and event information in this embodiment are internal information.

[0503] In step SX103b, the NEF sends information to the A-IoTF to cancel the periodic operation.

[0504] In some embodiments, if the A-IoTF is available and an interface exists between the NEF and the A-IoTF, the NEF directly invokes the A-IoTF service to cancel the periodic inventory process or unsubscribe from periodic inventory notifications. This message may include device information, location information, time information, event information, and a message to cancel the periodic operation. It should be understood that if step SX102 is executed, the device information, location information, time information, and event information in this embodiment are internal information.

[0505] In step SX104, A-IoTF sends information to AMF to cancel the periodic operation.

[0506] In some embodiments, in case 1, the A-IoTF may call an AMF service or an A-IoTF service to send information to cancel the periodic operation. The A-IoTF may call a service message to send information to cancel the periodic operation.

[0507] In some embodiments, the difference between the cancel service message and the cancel periodic operation message is that the cancel service message is an A-IoTF or AMF service message, and it may include application layer cancel periodic operation information as a parameter.

[0508] In some embodiments, the information sent by the AMF may be triggered in the following two situations:

[0509] Case 2: Step SX104 is skipped and the AMF is triggered by the information from the NEF in step SX103a-1; or

[0510] Case 3: The A-IoTF invokes the cancel periodic inventory service, and the AMF transparently forwards the information. For Case 3), execute step SX104. The AMF is triggered by step SX104, i.e., the message from the A-IoTF.

[0511] In some embodiments, case 1 + case 2 + case 3 are all possible cases.

[0512] In step SX105a-1, the AMF sends information to the UE to cancel the periodic operation.

[0513] In step SX105a-2, the UE sends information to the A-IoT device to cancel the periodic operation.

[0514] In step SX105b, AMF sends information to the A-IoT device to cancel the periodic operation.

[0515] In some embodiments, after being triggered by NEF or A-IoTF, AMF sends information to UE or A-IoT device, as described in case a and case b, respectively.

[0516] Case a: Topology 1

[0517] In some embodiments, the AMF sends information to the UE via the RAN. For example, the AMF may use an uplink non-access stratum transport (DL NAS TRANSPORT) message to transmit a message from the NEF or A-IoTF. The AMF may include the message from the NEF or A-IoTF in an A-IoT container.

[0518] The UE that receives the message may stop the periodic operation or stop reporting the periodic inventory results.

[0519] In some embodiments, optionally, after receiving the message sent by the AMF, the UE may send a message (e.g., an application layer message) to the A-IoT device.

[0520] The UE can use device information, location information, time information and event information as well as the specific device ID / group ID of the event to broadcast information to cancel periodic operations; or the UE can send information to cancel periodic operations to specific A-IoT devices, and the UE can use device information, location information, and time information to retrieve these devices.

[0521] The information sent from the UE to the A-IoT device may include cancel period inventory information (application layer), as well as device information, location information, time information, and event information.

[0522] Case b: Topology 2

[0523] In some embodiments, the AMF sends information to the A-IoT device through the RAN, or sends information to the RAN, and the RAN then sends information to the A-IoT device.

[0524] The AMF can use the device information, location information and time information to retrieve the appropriate RAN node and send information to the RAN node.

[0525] The RAN node can forward the message or send a new message to cancel the periodic inventory message. The message can include cancellation information (application layer) and device information, location information, time information, and event information. The RAN can also broadcast the message based on the information or send it to a specific A-IoT device.

[0526] In some embodiments, the A-IoT device receives information from the UE or RAN, identifies the application layer information (if included), and sends an acknowledgment (ACK) message to the UE or RAN.

[0527] When the device information, location information, time information, and event information all match, the A-IoT device can send an ACK.

[0528] In step SX106a-1, the A-IoT device sends an ACK message to the UE to cancel the periodic operation.

[0529] In some embodiments, the ACK message for canceling the periodic operation is used to notify the UE of confirmation of canceling the periodic operation.

[0530] In some embodiments, for a DO-DTT periodic inventory situation, steps SX105a-2 and SX106a-1 may be omitted.

[0531] In step SX106a-2, the UE sends an ACK message to cancel the periodic operation or a response message to cancel the periodic operation to the AMF.

[0532] In some embodiments, the UE sends an ACK message or a cancel periodic operation response message via the RAN to notify the AMF of the result of canceling the periodic operation. The UE can collect and filter ACKs from A-IoT devices.

[0533] For example, the UE may send a UL NAS TRANSPORT message to the AMF via the RAN, and include an ACK / response message in the A-IoT container. The response message may include device information, results, and event information of the A-IoT device for which the UE received the ACK.

[0534] In step SX106b, the A-IoT device sends an ACK message to the AMF to cancel the periodic operation.

[0535] In some embodiments, the A-IoT device sends an ACK message to cancel the periodic operation to notify the AMF of the ACK message through the RAN, or sends a message to the RAN to notify the ACK of the cancellation message, and the RAN may send a message to the AMF to notify the result of the cancellation message. The information from the RAN may include device information, results, and event information.
