Taking the access network device as a base station as an example, as shown in Figure 2A, the Ambient IOT device can directly communicate with the base station in both directions, including but not limited to transmitting environmental Internet of Things data and / or signals.

[0279] Refer to Figure 2B, which is another network architecture diagram shown according to an embodiment of the present disclosure.

As shown in Figure 3A, the Ambient IOT system can support the Non-Access Stratum (NAS) architecture, so that the Ambient IOT device and the core network device can communicate through the logical interface (Logical interface) between the NAS layer (layer) or the application (Application) layer, and the Ambient IOT device and the access network device can achieve anti-collision (Anti-Collision) communication through the Medium Access Control (MAC) layer, and / or, the Ambient IOT device and the access network device can communicate through the physical layer interface (PHY interface) of the physical layer (PHY).

[0283] Refer to Figure 3B, which is a schematic diagram of another signaling transmission method according to an embodiment of the present disclosure. As shown in Figure 3B, for an Ambient IOT system that does not support the NAS architecture, Anti-Collision communication can be achieved between the Ambient IOT device and the access network device through the MAC layer, and / or, communication can be achieved between the Ambient IOT device and the access network device through the PHY interface of the PHY layer; in addition, communication can be achieved between the access network device and the core network device through the Next Generation Core Network Protocol (NGAP) protocol, the Stream Control Transmission Protocol (SCTP) or the Physical Layer / Data Link Layer (L1 / L2) protocol.

[0314] It should be noted that, in more possible implementations, the above steps S4101 to S4102 are optional, and the access network device can determine the second information by itself without receiving the second information sent by the core network device to obtain the second information.

[0315] In some embodiments, the access network device may determine the second information based on preconfiguration, but is not limited thereto. The access network device may also determine the second information in other ways.

[0316] Step S4103: The access network device sends second information to the first Ambient IoT device.

[0317] In some embodiments, the first Ambient IoT device receives the second information sent by the access network device, so that the first Ambient IoT device can obtain the second information.

[0318] It should be noted that the first Ambient IoT device may be any Ambient IoT device in the Ambient IoT system.

[0319] In some embodiments, the access network device may send the second information to multiple Ambient IoT devices, including the first Ambient IoT device, so as to achieve the purpose of sending the second information from the access network device to the first Ambient IoT device.

[0320] Step S4104: The first Ambient IoT device is matched with the access network device based on the second information.

[0321] In some embodiments, the first Ambient IoT device may compare the received second information with information in its own device identifier, so that the first Ambient IoT device can match the first Ambient IoT device with the access network device.

[0322] It should be noted that, in more possible implementations, the above steps S4103 to S4104 are optional, that is, the access network device does not need to send the second information to the first Ambient IoT device, but directly sends the first information to the access network device through step S4105, so that the access network device can match the Ambient IoT device based on the first information and the second information.

[0323] In some embodiments, the first information includes relevant information of the first Ambient IoT device, so that the access network device can compare the first information with the second information to achieve matching between the access network device and the first Ambient IoT device.

[0324] For example, the first information may include information related to the device identification of the first Ambient IoT device, so that the access network device can compare the first information with the second information to achieve matching between the access network device and the first Ambient IoT device.

[0325] The first information will be described in detail in the following step S4105 and will not be repeated here.

[0326] Step S4105: The first Ambient IoT device sends first information to the access network device.

[0327] In some embodiments, the access network device receives first information sent by the first Ambient IoT device.

[0328] In some embodiments, the name of the first information is not limited, and it can be, for example, "device-related information", "identification-related information", "device reply information", "device feedback information", "reply information based on device identification", etc.

[0329] In some embodiments, the first information includes a complete device identifier of the first Ambient IoT device; or, the first information includes a partial device identifier of the first Ambient IoT device; or, the first information includes a temporary identifier of the first Ambient IoT device.

[0330] For example, the first information includes the complete device identification of the first Ambient IoT device, and the first information may be the entire device identification of the first Ambient IoT device.

[0331] For another example, the first information includes a partial device identifier of the first Ambient IoT device, and the first information may be a part of the device identifier of the first Ambient IoT device.

[0332] Taking the example that the first information includes a partial device identification of the first Ambient IoT device, the device identification of the first Ambient IoT device may include a part indicating the device type and a part uniquely identifying the device, then the first information may include the part of the device identification of the first Ambient IoT device that uniquely identifies the device.

[0333] For another example, the first information includes a temporary identifier of the first Ambient IoT device. The temporary identifier can be a random number, for example, a 16-bit random number, which can be used to uniquely identify an Ambient IoT device to distinguish between different Ambient IoT devices; for another example, the temporary identifier can be a 16-bit value, which can be used for device security verification, ensuring the integrity of the communication process, and other processes.

[0334] In some embodiments, the first information is fully readable by the access network device; or, the first information is unreadable by the access network device; or, the first information is partially readable by the access network device.

[0335] It should be noted that, in the case where the first Ambient IoT device matches the access network device based on the second information, the first information may be fully readable by the access network device, or the first information may be unreadable by the access network device, or the first information may be partially readable by the access network device. In the case where the access network device matches the first Ambient IoT device based on the first information, the first information may be fully readable by the access network device, or the first information may be partially readable by the access network device, with the readable portion at least including the device identifier of the first Ambient IoT device.

[0336] In some embodiments, the first information may also include information transmitted by the first Ambient IoT device to the core network device. The embodiment of the present disclosure does not limit the specific content of the information transmitted by the first Ambient IoT device to the core network device.

[0337] Step S4106: The access network device generates a first identifier based on the first information.

[0338] In some embodiments, the access network device may generate a first identifier specific to a Radio Access Network (RAN) based on the first information.

[0339] The first identifier is used to uniquely identify the first Ambient IoT device in the access network device. For example, the first identifier is used to uniquely identify the first Ambient IoT device in the access network device via a next generation (NG) interface.

[0340] In some embodiments, the name of the first identifier is not limited, and it can be, for example, "specific identifier within the access network", "RAN device ID", "RAN UE NGAP ID", "RAN Device NGAP ID", etc.

[0341] In some embodiments, the terms "radio access network (RAN)", "radio", "wireless", "access network (AN)", "RAN-based" and the like may be used interchangeably.

[0351] In some embodiments, the second indication information is used to instruct the access network device to transparently transmit the first information to the core network device. For example, for an Ambient IoT system that supports the NAS architecture, the second indication information may be a Device Uplink Non-Access Stratum NAS Protocol Data Unit (Device UL NAS PDU), so that the second indication information may indicate that the first information is uplink signaling sent from the first Ambient IoT device to the core network device.

The access network device can directly transparently transmit the second information received from the first Ambient IoT device to the core network device.

[0355] In some embodiments, the second indication information is used to instruct the access network device to send the first information to the core network device via explicit signaling. For example, for an Ambient IoT system that does not support the NAS architecture, the second indication information may be device information (Info from device), so that the second indication information can indicate that the first information is from the first Ambient IoT device and needs to be transmitted to the core network device.

[0356] Optionally, the second indication information is used to instruct the access network device to send the first information to the core network device through explicit signaling. The access network device can encapsulate the first information received from the first Ambient IoT device, and then send the encapsulated message to the core network device to realize the transmission of the second information.

[0357] In some embodiments, the third indication information is used to indicate location information of the first Ambient IoT device.

[0358] Optionally, the location information of the first Ambient IoT device may be a cell identifier of a cell where the first Ambient IoT device resides, or the location information of the first Ambient IoT device may be tracking area (TA) information of a cell where the first Ambient IoT device resides, but is not limited thereto.

[0359] In some embodiments, terms such as "cell", "component carrier (CC)", "frequency carrier", and "carrier frequency" may be used interchangeably.

[0360] In some embodiments, the fourth indication information is used to indicate that the device to communicate with the core network device is an Ambient IoT device.

[0361] Step S4108: The core network device performs a second operation based on the first message.

[0362] In some embodiments, the second operation may include at least one of authenticating the first Ambient IoT device, generating a second identifier for the first Ambient IoT device, and determining whether to communicate with the first Ambient IoT device, but is not limited thereto.

[0363] The second identifier is used to uniquely identify the first Ambient IoT device in the core network device. For example, the second identifier is used to uniquely identify the first Ambient IoT device in the core network device via an NG interface.

[0364] In some embodiments, the name of the second identifier is not limited, and it can be, for example, "specific identifier within the core network", "AMF device ID", "AMF UE NGAP ID", "AMF Device NGAP ID", etc.

[0365] In more possible implementations, the core network device may further save the first indication information and the third indication information included in the first message as the context of the first Ambient IoT device.

[0366] Step S4109: The core network device sends a second message to the access network device.

[0367] In some embodiments, the core network device may send the second message to the access network device when there is downlink information to be sent to the first Ambient IoT device, but is not limited thereto.

[0368] In some embodiments, the access network device receives the second message sent by the core network device.

[0369] In some embodiments, the second message may be an NGAP message, but is not limited thereto.

[0370] In some embodiments, the name of the second message is not limited, and it may be, for example, "second NGAP message" or the like.

[0371] In some embodiments, the second message is at least used for the access network device to transmit information sent by the core network device to the first Ambient IoT device, but is not limited thereto, and the second message may further include more information.

[0375] In some embodiments, the sixth indication information is used to indicate the third information that the transmission core network device sends to the first Ambient IoT device.

[0376] In some embodiments, the sixth indication information is used to instruct the access network device to transparently transmit the third information to the first Ambient IoT device. For example, for an Ambient IoT system that supports a NAS architecture, the sixth indication information may be a device downlink non-access stratum protocol data unit (Device Downlink Non-Access Stratum NAS Protocol Data Unit, Device DL NAS PDU), so that the sixth indication information may indicate that the third information is downlink signaling sent from the core network device to the first Ambient IoT device.

[0378] Optionally, the sixth indication information is used to instruct the access network device to transparently transmit the third information to the first Ambient IoT device. The access network device can directly transparently transmit the third information received from the core network device to the first Ambient IoT device.

[0588] According to the solution provided by the embodiment of the present disclosure, it is possible to solve the interaction between access network devices (such as gNB, or NG-RAN node, etc.) and core network devices (such as AMF, or core network devices for Ambient IoT, etc.) in different situations to support specific Ambient IoT devices to support communication between core network devices and Ambient IoT devices.

[0589] Taking the access network device as the NG-RAN node and the core network device as the AMF as an example, the NG-RAN node can perform the device selection process of the Ambient IoT device based on the mask-related information provided by the AMF.

[0590] In some embodiments, the mask-related information includes at least one of the mask type, the mask starting position, the mask length, the mask value, and the information requirement responded by the Ambient IoT device (ie, device).

[0591] In some embodiments, the NG-RAN node may generate a RAN-specific device ID based on feedback from the Ambient IoT device, to uniquely identify an Ambient IoT device within the NG-RAN.

[0592] In some embodiments, the NG-RAN node may send device information received from the Ambient IoT device to the AMF via a newly defined NGAP message.

[0593] The device information may be fully readable by the NG-RAN node, or may be non-readable by the NG-RAN node (such as NAS PDU), or may be partially readable by the NG-RAN node.

[0594] In some embodiments, the NGAP message sent by the NG-RAN node to the AMF may include at least one of the RAN Device ID, the Device UL NAS PDU (corresponding to the network topology shown in Figure 3A), the Device related information (corresponding to the network topology shown in Figure 3B), and the Device location information, but is not limited thereto.

[0595] In some embodiments, the AMF may perform further operations based on the above information received from the NG-RAN node, including but not limited to authenticating and identifying the Ambient IoT device, deciding whether to further communicate with the Ambient IoT device, etc.

[0596] In some embodiments, the NG-RAN node may receive information related to the Ambient IoT device from the AMF, and the information related to the Ambient IoT device may be sent by the AMF to the NG-RAN node via a newly defined NGAP message.

[0597] In some embodiments, the NGAP message sent by the AMF to the NG-RAN node may include at least one of RAN Device ID, AMF Device ID, Device UL NAS PDU (corresponding to the network topology shown in Figure 3A), Device related information (corresponding to the network topology shown in Figure 3B), Device context release indication, and Device context retention time, but is not limited thereto.

[0598] In some embodiments, the NG-RAN node may perform further operations based on the above information received from the AMF, including but not limited to inventory, access, and release of Ambient IoT device context.

[0599] For ease of understanding, the communication method described above is further illustrated below using a specific example. Referring to FIG6 , FIG6 is an interactive diagram illustrating a communication method according to an embodiment of the present disclosure. As shown in FIG6 , the method includes:

[0600] In step S6101, the core network (such as AMF) initiates an Ambient IoT-related task (for example, an inventory task).

[0601] In some embodiments, the task information includes mask-related information, and the mask-related information is used by the NG-RAN node to select the Ambient IoT device.

[0602] In some embodiments, the mask-related information includes at least one of the mask type, the mask starting position, the mask length, the mask value, and the information requirement of the Ambient IoT device response.

[0603] In some embodiments, the mask type is used to indicate the identification type to be matched, such as EPC type, TID type, etc., but is not limited thereto.

[0604] In some embodiments, the identification type indicated by the mask type may also be a temporary identification of the Ambient IoT device in a certain area, that is, an identification that is valid only within the area.

[0605] In some embodiments, the mask starting position is used to indicate the starting position of the identifier to be matched.

[0606] In some embodiments, the mask length is used to indicate the length of the field from the start position to the end position of the identifier to be matched.

[0607] In some embodiments, the mask value is used to indicate a specific value that the identifier of the Ambient IoT device needs to match.

[0608] In some embodiments, the information requirements of the Ambient IoT device response are used to indicate how the Ambient IoT device responds to the NG-RAN node if the match is successful. For example, the Ambient IoT device needs to respond with all the information in the identifier, or the Ambient IoT device only needs to respond with part of the information in the identifier.

[0609] In step S6102, the NG-RAN node sends mask-related information to the Ambient IoT device during the process of initiating Ambient IoT device selection. If the Ambient IoT device is activated, the Ambient IoT device can compare the mask-related information with the identifier in the Ambient IoT device (for example, EPC, TID, User memory, etc.). If a match is successful, a backscatter reply is sent to the NG-RAN node, and the reply can carry the identifier information of the Ambient IoT device.

[0610] In some embodiments, the identification information of the Ambient IoT device may be the entire device identification or a partial device identification.

[0611] In step S6103, the NG-RAN node generates a RAN device ID based on the response from the Ambient IoT device, which can uniquely identify the Ambient IoT device in the NG-RAN node. That is, the RAN device ID is used to uniquely identify an Ambient IoT device in the NG-RAN node.

[0612] If the response of the Ambient IoT device includes information that needs to be transmitted to the AMF, the NG-RAN node can send a first NGAP message (e.g., UL Device info transfer message) to the AMF, and the first NGAP message is used to transmit the information of the Ambient IoT device to the AMF.

[0613] In some embodiments, the first NGAP message includes at least one of RAN Device ID, Device UL NAS PDU, Info from device, and Device location information.

[0614] In some embodiments, the RAN Device ID is used to uniquely identify the Ambient IoT device within the NG-RAN node through the NG interface.

[0615] In some embodiments, the Device UL NAS PDU is used to indicate that the PDU is UL signaling sent by the Ambient IoT device to the AMF.

[0616] In some embodiments, Info from device is used to explicitly indicate information from the Ambient IoT device, and the information needs to be transmitted to the AMF.

[0617] In some embodiments, the device location information is used to indicate the location information of the Ambient IoT device, where the location information includes, but is not limited to, the cell ID of the cell to which the Ambient IoT device responds, or the TA information of the cell to which the Ambient IoT device responds.

[0618] In some embodiments, the AMF receives the first NGAP message and saves the RAN Device ID and Device location information therein as the context of the Ambient IoT device.

[0619] In some embodiments, the AMF may initiate the Ambient IoT device authentication process based on the first NGAP message.

[0620] In step S6104, if the AMF has downlink information to send to the Ambient IoT device (for example, authentication, authorization, read and write operations, etc.), the AMF may send a second NGAP message (for example, DL Device info transfer message) to the NG-RAN node. The second NGAP message is used to transmit the information sent by the AMF to the Ambient IoT device.

[0621] In some embodiments, the second NGAP message includes at least one of RAN Device ID, AMF Device ID, Device DL NAS PDU, Info from AMF, Device context release indication, and Device context retention time.

[0622] In some embodiments, the RAN Device ID is used to uniquely identify the Ambient IoT device within the NG-RAN node through the NG interface.

[0623] In some embodiments, the AMF Device ID is used to uniquely identify the Ambient IoT device within the AMF node through the NG interface.

[0624] In some embodiments, the Device DL NAS PDU is used to indicate that the PDU is DL signaling sent by the AMF to the Ambient IoT device.

[0625] In some embodiments, Info from AMF is used to explicitly indicate information from AMF, and the information needs to be transmitted to the Ambient IoT device.

[0626] In some embodiments, the Device context release indication is used to indicate whether the NG-RAN node needs to release the context of the Ambient IoT device immediately.

[0627] Optionally, if the AMF communicates with the Ambient IoT device only once, or if the AMF will not communicate with the Ambient IoT device again for a period of time, the AMF can instruct the NG-RAN node to release the context information related to the Ambient IoT device.

[0628] In some embodiments, the Device context retention time is used to indicate when the NG-RAN node releases the context of the Ambient IoT device.

[0629] In step S6105, the NG-RAN node receives the second NGAP message and performs relevant operations according to the information in the second NGAP message.

[0630] In some embodiments, the operations performed include, but are not limited to, inventorying, accessing, transmitting device UL NAS PDU to the Ambient IoT device, releasing the context of the Ambient IoT device, etc.
