[0162] Currently, cellular passive IoT mainly studies three types of relay air interface topologies. Taking the relay device (UE) as an example, they are as follows: Figure 1 , Figure 2 and Figure 3 As shown. Figure 1 , Figure 2 and Figure 3 The diagram includes base stations, UEs, and AIoT devices. Arrows in the diagram indicate the signaling, power, command, and uplink information transmission directions of the Uu interface. The Uu interface is used to enable communication between the UE and Wideband Code Division Multiple Access (W-CDMA). The relay device plays a role similar to home gateways, Customer Premises Equipment (CPE), and UEs in a cellular network. It is managed by the base station and the cellular network, and according to the cellular network configuration, performs downlink excitation and uplink signal reception operations for AIoT devices, also known as tags.

[0163] In existing home scenarios, the network topology of cellular networks, such as Figure 4As shown. Residential Gateways (RGs), such as 5G-RGs (5th Generation Mobile Communication Technology-Residential Gateways), typically access the Gateway Function (AGF) via wired access. The AGF connects to the Core Network (CN), such as the 5G Core Network, through the N2 and / or N3 interfaces to register within the Core Network. After completing authentication and other processes, it establishes a PDU session for UE data transmission. The N2 interface is the interface between the Session Management Function (SMF) and the base station, primarily used for session management and policy control. The N3 interface is the interface between the User Plane Function (UPF) and the base station, primarily used for user plane data transmission. For RGs such as CPEs, they typically have wireless access capabilities. This means that RGs such as CPEs access the base station (gNB) via the N1 air interface to complete air interface procedures such as random access. The base station uses a similar registration and authentication process to that of a UE to establish a connection with the core network via the N2 and / or N3 interfaces, and establishes a PDU session for UE data transmission. Communication between the UE and the RG occurs through a Wireless Local Area Network (WLAN), and this communication is not subject to or does not require control by the cellular network.

[0164] In a relay architecture, the cellular network only needs to manage the RG (Regulator). After the RG completes registration and authentication, a PDU (Power Distribution Unit) session is established for the RG. UE data reported via the WLAN protocol can then be uploaded to the data network (DN) through the RG's PDU session. The cellular network cannot manage the UE to the RG or allocate resources.

[0165] Network topology in cellular passive IoT, such as Figure 5 As shown. Figure 5The network nodes for newly added AIoT devices (AIoT devices and / or Ambient IoT Devices) can be implemented. AIoT devices can communicate directly with relay devices in a unified transmit-receive manner; alternatively, they can achieve separate transmit-receive communication with relay devices by splitting the forward and backward links. For example, forward data from the AIoT device can be sent by the UE, and reverse data can be received by the RG. Relay devices can be fixed devices like RGs or mobile devices like UEs and / or CPEs. Regardless of whether a unified transmit-receive or separate architecture is used, the communication between AIoT devices and relay devices must use the cellular passive IoT protocol. Unlike the aforementioned home scenario, communication between AIoT devices and relay devices needs to be managed by the cellular network. The resources for AIoT devices to access and transmit via the AIoT air interface should be allocated by the cellular network. That is, while managing the relay devices, the cellular network must specify the network resources available for AIoT device-to-relay communication, such as PDU slicing services, air interface frequencies, available bandwidth, and storage parameters.

[0166] Currently, the cellular network's management mechanism for access devices only allows it to manage devices that connect directly via the N1 interface or wired interface. It cannot manage devices that connect via RG and / or relay devices, meaning it cannot manage the communication between relay devices and AIoT devices.

[0167] Based on this, in various embodiments of this application, a first network function sends first information to a network device. The first information indicates that the first terminal can function as a reader / writer, has reader / writer capabilities, or can execute AIoT services, for the network device to allocate resources for transmitting AIoT service-related information to the first terminal. The network device receives the first information and sends second information to the first terminal. The first terminal receives the second information sent by the network device, whereby the second information at least indicates the first resources allocated to the first terminal, and these first resources are used to transmit AIoT service-related information. In this scheme, the network device receives the first information and allocates first resources to the first terminal, which can function as a reader / writer, has reader / writer capabilities, or can execute AIoT services, to transmit AIoT service-related information between the first terminal and the AIoT device. This enables the cellular network to manage the communication between the first terminal and the AIoT device.

[0168] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0169] This application provides a resource allocation method applied to network devices, including base stations, which include gNBs and / or gNodeBs. Figure 6 As shown, the method includes:

[0170] Step 601: Receive first information, the first information indicating that the first terminal can act as a reader or has reader capability or can perform AIoT services.

[0171] Here, the first information is determined based on the registration information of the first terminal. The registration information indicates the capabilities of the first terminal, or carries capability information or capability indication information of the first terminal. The first terminal can be understood as a relay device between network devices and AIoT devices. The capability information or capability indication information of the first terminal indicates whether the first terminal can act as a reader / writer, whether it has reader / writer capabilities, or whether it can perform AIoT services. The first terminal can send registration information to a first network function, such as an AMF. The first network function can determine the first information based on the registration information sent by the first terminal and send the first information to the network device.

[0172] In one embodiment, receiving the first information includes:

[0173] Receive the first message sent by the first network function.

[0174] Here, the first network function includes, but is not limited to, AMF.

[0175] When a network device needs to receive the first information sent by the first network function, it can reply with an acknowledgment message to the first network function, such as sending a fifth message to the first network function. The fifth message indicates whether the network device has received the first information or not. For example, if the network device does not receive the first information sent by the first network function within a set time period, it can send a fifth message to the first network function to indicate that the network device has not received the first information.

[0176] In this embodiment, the sender of the first information is clearly identified, which facilitates the receipt of the first information and provides a basis for subsequent resource allocation to the first terminal.

[0177] In one embodiment, the first information includes one or more of the following:

[0178] First capability information, the first capability information indicates that the first terminal can be used as a reader or has reader capability;

[0179] Second capability information, the second capability information represents that the first terminal can perform AIoT services;

[0180] The third capability information indicates that the first terminal can only send signals related to AIoT services in a specific geographical location area and / or on specific communication resources.

[0181] The fourth capability information indicates that the first terminal can only receive signals related to AIoT services in a specific geographical location area and / or specific communication resources;

[0182] The fifth capability information represents that the first terminal supports sending and receiving signals related to AIoT services in a specific geographical location area and / or specific communication resources.

[0183] Here, the first capability information indicates that the first terminal can act as a reader or has reader capabilities, that is, the first terminal can interact with AIoT devices.

[0184] The third capability information indicates that the first terminal can only send AIoT service-related signals in a specific geographical area and / or on specific communication resources. For example, the first terminal can only send AIoT service-related signals within the same time period.

[0185] The fourth capability information indicates that the first terminal can only receive signals related to AIoT services in a specific geographical area and / or specific communication resources. For example, the first terminal can only receive signals related to AIoT services within the same time period.

[0186] The fifth capability information represents that the first terminal supports sending and receiving signals related to AIoT services in a specific geographical area and / or specific communication resources. For example, the first terminal supports sending and receiving signals related to AIoT services within the same time period.

[0187] The first information may include any one or more of the aforementioned capability information. The first information may also include at least first capability information and / or second capability information, and may also include third, fourth, or fifth capability information.

[0188] The first information can be carried in the first instruction, which can be a relay capability notification (N2_RelayCapacityNotify) instruction. The first instruction is as follows: Figure 7 As shown, Figure 7 This is merely an example and does not constitute a limitation; such as Figure 7As shown, an Internet standard uses an octet equal to 8 bits. The first instruction includes a first relay identifier field and a first instruction type field. The first relay identifier field occupies bits 1 to 4 of Octet1, and the first instruction type field occupies bits 5 to 8 of Octet1. Octet2-n indicates the capabilities of the first terminal and is used to carry first capability information and / or second capability information and / or third capability information and / or fourth capability information and / or fifth capability information. n can be determined based on the number of capability information. The first instruction type field is used to identify the first instruction between the Radio Access Network (RAN) and the Core Network (CN). In other words, the first instruction type field is used for the RAN and CN to identify the first instruction. The first relay identifier field is used to identify the identity of the first terminal. The first relay identifier field can carry one or more of the following identifiers: Subscription Concealed Identifier (SUCI), Globally Unique Temporary Identity (GUTI) such as 5G-GUTI, Permanent Equipment Identity (PEI), and UE Radio Capability Identity (ID).

[0189] In this embodiment, the content of the first information is clearly defined to help the network device predict the capability of the first terminal to perform AIoT services based on the first information, and to determine the second information.

[0190] Step 602: Send the second information to the first terminal.

[0191] The second information at least indicates a first resource allocated to the first terminal, which is used to transmit information related to AIoT services. For example, the second information may include at least the frequency point on which the AIoT service is performed and / or the bandwidth used to perform the AIoT service.

[0192] In one embodiment, the second information includes one or more of the following:

[0202] Here, the modulation and coding scheme (MCS) used to execute AIoT services is not limited.

[0203] The role of the first terminal in performing AIoT services can be to only receive signals related to AIoT services, to only send signals related to AIoT services, or to both send and receive signals related to AIoT services.

[0204] The transmission modes of AIoT services include a first transmission mode and / or a second transmission mode. The first transmission mode indicates that the first terminal only forwards AIoT service-related instructions and / or forwards response information sent by AIoT devices. The second transmission mode indicates that the first terminal autonomously generates AIoT service-related instructions and / or executes AIoT services and / or receives response information sent by AIoT devices. The first transmission mode can be understood as a transparent transmission mode, and the second transmission mode can be understood as an autonomous mode.

[0205] It is worth noting that when the initiator of allocating the first resource to the first terminal is a network device, the second information can be carried in the second instruction, such as the second instruction being the Base Station to Reader (B2R) _ Start AIoT Service Request Instruction; when the initiator of allocating the first resource to the first terminal is the first terminal, the second information can be carried in the third instruction, such as the third instruction being the B2R _ Service Air Interface Resource Allocation Instruction.

[0206] The second instruction is as follows Figure 8 As shown, Figure 8 This is merely an example and does not constitute a limitation; such as Figure 8As shown, the second instruction includes a second relay identifier field, a second instruction type field, a bandwidth field, and a stationary frequency point field. The second relay identifier field occupies bits 1 to 4 of Octet1, and the second instruction type field occupies bits 5 to 8 of Octet1. The bandwidth field is used to characterize the bandwidth used to execute the AIoT service and occupies bits 1 to 4 of Octet2. The stationary frequency point field is used to characterize the stationary frequency point used to execute the AIoT service and occupies bits 5 to 8 of Octet2. Octet3-m can be used to indicate one or more of the following: the frequency hopping pattern used to execute the AIoT service, the MCS (Multi-Segment Code) used to execute the AIoT service, the time of executing the AIoT service, the role of the first terminal in executing the AIoT service, and the transmission mode of the AIoT service. m can be determined based on the number of characterization items. The time of executing the AIoT service, the role of the first terminal executing the AIoT service, and the transmission mode of the AIoT service can be indicated using an Octet. For example, the time of executing the AIoT service occupies bits 5 to 8 of Octetm, the role of the first terminal executing the AIoT service occupies bits 3 to 4 of Octetm, and the transmission mode of the AIoT service occupies bits 1 to 2 of Octetm.

[0207] It should be noted that, apart from the difference in the content of the type field of the second instruction, the content of other fields of the third instruction and the second instruction can be the same or different.

[0208] The second instruction type field is used to identify the second instruction between the first terminal and the RAN; the second relay identifier field is used to identify the identity of the first terminal, for example, in the New Radio (NR) interface, the second relay identifier field can carry one or more of the following identifiers: Radio Network Temporary Identifier (RNTI), SUCI, 5G-GUTI, PEI, UE Radio Capability ID; the camping frequency field is used to indicate the air interface frequency that the first terminal can camp on when performing AIoT services, the camping frequency field can identify one air interface frequency or a group of different air interface frequencies; the bandwidth field is used to indicate the bandwidth that the first terminal can use when performing AIoT services, the bandwidth field can identify one bandwidth or a group of different bandwidths; the MCS field is used to indicate the modulation and coding scheme that the first terminal can use when performing AIoT services. When the transmission mode of the AIoT service is the first transmission mode, the MCS field can correspond to one MCS scheme. When the transmission mode of the AIoT service is the second transmission mode, the MCS field can correspond to multiple different MCS schemes for the first terminal to choose from.

[0209] In this embodiment, the content of the second information is clearly defined, the first resource is allocated to the first terminal, and the cellular network manages the communication between the first terminal and the AIoT device.

[0210] In one embodiment, for a scenario where the first terminal initiates the allocation of a first resource, before sending the second information to the first terminal, the resource allocation method further includes:

[0211] The system receives a first request sent by the first terminal, the first request being used to request the activation of AIoT services.

[0212] Here, the first request can carry a fourth instruction, for example, the fourth instruction is a Reader to Base Station (R2B) request instruction to enable AIoT services. The fourth instruction is as follows: Figure 9 As shown, Figure 9 This is merely an example and does not constitute a limitation; such as Figure 9 As shown, the fourth instruction includes a third relay identifier field and a third instruction type field. The third relay identifier field occupies bits 1 to 4 of Octet1-q, and the third instruction type field occupies bits 5 to 8 of Octet1-q, where q can be determined based on actual needs. The third instruction type field is used to identify the fourth instruction between the first terminal and the RAN; the third relay identifier field is used to identify the identity of the first terminal, for example, identifying the identity of the first terminal within the NR, i.e., for the mobile communication network to identify the first terminal. The third relay identifier field can carry one or more of the following identifiers: RNTI, SUCI, 5G-GUTI, PEI, UE Radio Capability ID.

[0213] In this embodiment, when the first terminal initiates the allocation of the first resource, the network device performs resource allocation based on the first request.

[0214] In one embodiment, the resource allocation method further includes:

[0215] The system receives third information sent by the first terminal, the third information indicating information about a second terminal that can cooperate with the first terminal to perform AIoT services.

[0216] It is worth noting that the instructions carried in the first request and the instructions carried in the third information can be the same instruction.

[0217] In this embodiment, the network device can schedule multiple relay devices, namely the first terminal and the second terminal, based on third information to complete AIoT services, thereby improving the execution efficiency of AIoT services.

[0218] In one embodiment, the third information includes one or more of the following:

[0219] The identifier of the second terminal;

[0220] The second terminal has the capability to execute AIoT services;

[0221] The second terminal may or may not support frequency hopping;

[0222] The role of the second terminal in executing AIoT services;

[0223] The second terminal supports the following operating frequencies.

[0224] Here, the identifier of the second terminal may include, but is not limited to, one or more of the following: RNTI, SUCI, 5G-GUTI, PEI, UE Radio Capability ID.

[0225] The second terminal's ability to perform AIoT services includes at least one or more of the following: the role of the second terminal in performing AIoT services, whether the second terminal supports or does not support frequency hopping, and the operating frequencies supported by the second terminal.

[0226] The role of the second terminal in performing AIoT services can be to only receive signals related to AIoT services, to only send signals related to AIoT services, or to both send and receive signals related to AIoT services.

[0227] The third piece of information can be carried in the fifth instruction, for example, the fifth instruction is the R2B_Nearest Neighbor Search Result Reporting Instruction. The fifth instruction is as follows: Figure 10 As shown, Figure 10 This is merely an example and does not constitute a limitation; such as Figure 10As shown, the fifth instruction includes a fourth relay identifier field, a fourth instruction type field, the capability of the second terminal to perform AIoT services, and a list of identifiers for the second terminal. The fourth relay identifier field occupies bits 1 to 4 of Octet 1, and the fourth instruction type field occupies bits 5 to 8 of Octet 1. The capability of the second terminal to perform AIoT services occupies bits 1 to 4 of Octet 2, and the list of identifiers for the second terminal occupies bits 5 to 8 of Octet 2. The capability of the second terminal to perform AIoT services continues to occupy Octet 3-p, where p can be determined based on actual needs. The fourth instruction type field is used to identify the fifth instruction between the RAN and the first terminal. The fourth relay identifier field is used to identify the identity of the first terminal and can carry one or more of the following identifiers: RNTI, SUCI, 5G-GUTI, PEI, UE Radio Capability ID. It should be noted that, if the identifier list for the second terminal is defaulted, the Octet occupied by the capability of the second terminal to perform AIoT services may only indicate the capability of the first terminal to perform AIoT services, and not the capability of other relay devices to perform AIoT services.

[0228] In this embodiment, by clearly defining the content of the third information, it is possible to identify a second terminal that can cooperate with the first terminal to execute AIoT services, thereby helping to improve the execution efficiency of AIoT services.

[0229] In one embodiment, the resource allocation method further includes:

[0230] The system receives a fourth message sent by the first terminal, the fourth message indicating whether the first terminal can enable AIoT services or cannot enable AIoT services, or indicating whether the first terminal has the capability to perform AIoT services.

[0231] The fourth piece of information can be determined by the first terminal based on the currently executing service and its own capabilities. It is worth noting that if the first terminal cannot initiate AIoT services, the method for the first terminal to execute AIoT services needs to be re-determined. For example, in this case, the fourth piece of information can indicate the first terminal's capability to execute AIoT services, and the network device can resend the second piece of information to the first terminal based on this capability.

[0232] In this embodiment, receiving the fourth information sent by the first terminal can take into account the situation where the first terminal cannot start the AIoT service, so as to ensure the execution of the AIoT service.

[0233] In one embodiment, the fourth information includes one or more of the following:

[0241] It is worth noting that when the initiator of allocating the first resource to the first terminal is a network device, the fourth information can be carried in the sixth instruction, for example, the sixth instruction is R2B_AIoT service activation request confirmation instruction; when the initiator of allocating the first resource to the first terminal is the first terminal, the fourth information can be carried in the seventh instruction, for example, the seventh instruction is R2B_AIoT service air interface resource allocation confirmation instruction.

[0242] The sixth instruction is as follows Figure 11 As shown, Figure 11 This is merely an example and does not constitute a limitation; such as Figure 11As shown, the sixth instruction includes a fifth relay identifier field, a fifth instruction type field, the first terminal's ability to execute AIoT services, and a relay capability confirmation identifier field. The fifth relay identifier field occupies bits 1 to 4 of Octet 1, and the fifth instruction type field occupies bits 5 to 8 of Octet 1. The first terminal's ability to execute AIoT services occupies bits 1 to 4 of Octet 2, and the relay capability confirmation identifier field occupies bits 5 to 8 of Octet 2. The first terminal's ability to execute AIoT services continues to occupy Octet 3-f, where f can be determined based on actual needs. The fifth instruction type field is used to identify the sixth instruction between the first terminal and the RAN. The fifth relay identifier field is used to identify the identity of the first terminal and can carry one or more of the following identifiers: RNTI, SUCI, 5G-GUTI, PEI, UE Radio Capability ID. The relay capability confirmation identifier field indicates that the first terminal has received the second information and can start the AIoT service according to the second information, or indicates that the first terminal cannot start the AIoT service, or indicates that the first terminal cannot start the AIoT service according to the second information.

[0243] It should be noted that, apart from the content of the type field of the fifth instruction, the content of the other fields of the sixth and seventh instructions can be the same or different.

[0244] In this embodiment, clearly defining the content of the fourth information can further ensure the execution of AIoT services.

[0253] Here, the packet information of the AIoT device may include the AIoT device's identifier mask and / or the AIoT device's session state. The AIoT device's session state includes, for example, whether the AIoT device is interacting with the first terminal, and / or whether the AIoT device is not interacting with the first terminal. It is worth noting that the AIoT device's packet information is not visible in the RAN, nor in the first terminal and / or the second terminal; the AIoT device's packet information may be generated by the user platform and / or the core network and directly passed through to the AIoT device to help the first terminal select the AIoT device.

[0254] The selection command can be understood as the B2R_Select command. The selection command is as follows: Figure 12 As shown, Figure 12 This is merely an example and does not constitute a limitation; such as Figure 12 As shown, the selection instruction includes the number of AIoT devices, a sixth instruction type field, a sixth relay identifier field, and a priority field.

[0256] It should be understood that, when the sixth relay identifier field is used to identify the identity of the first terminal, the contents carried in the first, second, third, fourth, fifth, and sixth relay identifier fields may be the same or different.

[0257] In this embodiment, selecting the number of AIoT devices carried in the instruction facilitates the first terminal and / or the second terminal in generating and storing relevant access parameters, clearly defining the content carried in the instruction, and thus rationally allocating air interface resources for executing AIoT services, providing assurance for AIoT services.

[0294] In practical applications, after receiving the second information sent by the network device, the first terminal determines whether the network device's scheduling method for the first terminal is reasonable, based on the currently executed service and its own capabilities. If reasonable, the fourth information indicates that the first terminal can start the AIoT service, and the first terminal executes the AIoT service. If unreasonable, the fourth information indicates that the first terminal cannot start the AIoT service or indicates the first terminal's ability to execute the AIoT service.

[0340] The following description, using gNB as the network device and AMF as the first network function, will further elaborate on this application in conjunction with application embodiments.

[0341] This application's overall process diagram is as follows: Figure 16 As shown, it includes:

[0342] Step 1: The first terminal connects to the gNB via the air interface.

[0343] For example, the first terminal uses the same method as the 5G NR UE to establish an air interface connection with the gNB, completes random access, and resides in the core network.

[0344] Step 2: The first terminal registers in the core network, such as the 5G core network (5GC).

[0345] The first terminal sends a second request to the AMF through the N1 interface. The second request carries the first information, which indicates that the first terminal can act as a reader or has reader capabilities or can perform AIoT services. The AMF allocates a 5G-GUTI to the first terminal.

[0346] Step 3: The first terminal sends a PDU Session Establishment Request to the AMF, that is, the first terminal sends a third request to the first network function.

[0347] Step 4: Authentication (or Authorization) and PDU session establishment are performed in the first terminal, gNB, AMF, UPF, SMF, Policy Control Function (PCF), Unified Data Management (UDM), and DN.

[0348] Step 5: AMF sends the first message to gNB.

[0349] Step 6: gNB sends the fifth message to AMF.

[0350] Step 7: The AMF sends an N2_Select command to the gNB to determine the tag to be read.

[0351] It is worth noting that step 7 can be performed or not.

[0352] Step 8: gNB allocates the first resource to the first terminal.

[0353] Based on the first information, or based on the first information and the tag to be read to determine the second information, the second information is sent to the first terminal.

[0354] A schematic diagram of the control plane and data plane topology (integrated relay) in a cellular passive Internet of Things (IoT) system, as shown below. Figure 17 As shown. Figure 17The tag group has an AIoT control plane; the UE has WLAN data; the first terminal is a relay device between the gNB and the tag group, which has cellular passive service bearers and 5G NR service bearers. Cellular passive services can be understood as AIoT services, and the cellular passive service bearers include a first control plane and a first data plane. The 5G NR service bearers include a second control plane, a second data plane, and a third data plane. The gNB has an AIoT control plane and a 5G NR control plane; the AMF has an AIoT control plane and a 5G NR control plane; the UPF has cellular passive IoT service slice 1, 5G NR service slice 2.1, and 5G NR service slice 2.2. Specifically, the first control plane is used for uploading and receiving control commands and distributing AIoT services; the first data plane is used for uploading cellular passive IoT services; the second control plane is used for uploading and receiving control commands; the second data plane is used for uploading and receiving data; and the third data plane is used for uploading and receiving data for the UE. The tag's AIoT control plane, the first control plane, the gNB's AIoT control plane, and the AMF's AIoT control plane are sequentially connected; the first data plane is connected to cellular passive IoT service slice 1; the second control plane, the gNB's 5G NR control plane, and the AMF's 5G NR control plane are sequentially connected; the second data plane is connected to 5G NR service slice 2.1; WLAN data and the third data plane are sequentially connected to 5G NR service slice 2.2. Figure 17 It is not difficult to see that the relay device may have the ability to carry both AIoT services and 5G NR services. For 5G NR services, the relay device can perform services as a UE and can also pass 5G NR messages to other UE devices accessed through the relay device. Based on this, the gNB can act as the initiator to allocate the first resource to the first terminal, and / or the first terminal can act as the initiator to allocate the first resource to the first terminal.

[0355] When the gNB receives a higher-layer instruction such as the N2_Select instruction, the gNB initiates a diagram illustrating the allocation of the first resource to the first terminal, as shown below. Figure 18 As shown, it includes:

[0356] Step 1: gNB determines the capabilities of the first terminal and predicts the role of the first terminal in performing AIoT services based on the first information.

[0357] Step 2: The gNB sends the second information to the first terminal. The second information is carried in the B2R_Start AIoT Service Request Command.

[0358] When the transmission mode of the AIoT service in the second information is the first transmission mode, the first terminal only transparently forwards instructions related to the AIoT service, such as Query and / or forwards the response information sent by the AIoT device, such as the tag application layer identifier; the premise for using the first transmission mode is that the first terminal has established a PDU session with the core network, or the tag data can be forwarded from the AIoT control plane to the gNB and finally forwarded to the user platform.

[0359] When the transmission mode of the AIoT service in the second information is the second transmission mode, the first terminal, under the scheduling of the gNB, autonomously generates AIoT service-related instructions and / or executes AIoT services and / or receives response information sent by AIoT devices. Using the second transmission mode, the first terminal can establish a PDU session with the core network after completing the tag information collection, or forward the tag data from the AIoT control plane to the gNB and finally forward it to the user platform.

[0360] Step 3: The first terminal performs gNB permission judgment, that is, the first terminal determines whether the gNB's scheduling method for the first terminal is reasonable based on the currently executed business and its own capabilities.

[0361] Step 4: The first terminal sends the fourth information to the gNB, which is carried in the R2B_AIoT service activation request confirmation command.

[0362] Step 5: When the first terminal is operating in the first transmission mode, the gNB sends a Media Access Control Address Select (MAC_Select) command to the tag group.

[0363] Step Six: When the first terminal is operating in the second transmission mode, the gNB sends a selection command to the relay device to enable the first terminal to start the AIoT service.

[0364] When the first terminal receives an instruction from a higher-level user, a diagram illustrating the allocation of first resources to the first terminal is shown below. Figure 19 As shown, it includes:

[0365] Step 1: The first terminal performs a search for neighboring terminals to find potential joint transceiver terminals, i.e., the second terminal.

[0366] Step 2: The first terminal sends the third information to the gNB.

[0367] Step 3: The first terminal sends a first request to the gNB, for example, the gNB where it resides.

[0368] Step 4: gNB determines the capabilities of the first terminal and predicts the role of the first terminal in performing AIoT services based on the first information.

[0369] Step 5: The gNB sends the second information to the first terminal. The second information is carried in the B2R_Service Air Interface Resource Allocation Command.

[0370] Step Six: The first terminal performs gNB permission judgment, that is, the first terminal determines whether the gNB's scheduling method for the first terminal is reasonable based on the currently executed business and its own capabilities.

[0371] Step 7: The first terminal sends the fourth information to the gNB. The fourth information is carried in the R2B_AIoT service air interface resource allocation confirmation command.

[0372] Step 8: With the first terminal operating in the first transmission mode, the gNB sends a MAC_Select command to the tag group.

[0373] Step 9: When the first terminal is operating in the second transmission mode, the gNB sends a selection command to the first terminal to enable the first terminal to start the AIoT service.

[0374] Step 9: gNB sends the MAC_Select command to the first terminal.

[0375] Step 10: gNB sends a MAC_Query command to the first terminal.

[0376] Step 11: The tag group sends data feedback to the first terminal.

[0377] For example, data for tag 1 is fed back to data for tag v, where v is the number of tags in the tag group. Tag data may include tag identifiers and / or user area data.

[0378] Step 12: The first terminal sends a PDU Session establishment request to the AMF, that is, the first terminal sends a third request to the first network function.

[0379] Step 13: Authenticate and establish a PDU session in the first terminal, gNB, AMF, UPF, SMF, PCF, UDM, and DN.

[0380] It is worth noting that you can choose to perform steps 3 and 4, or steps 12 and 13.

[0381] Step 14: The first terminal sends tag data to the UPF.

[0382] The first terminal sends the tag group data it has read to the UPF through the established PDU Session.

[0383] Step 15: The UPF sends a tag data reception confirmation to the first terminal.

[0384] The first terminal receives the tag data reception confirmation from the UPF, thus completing this communication.

[0385] This application provides an overall workflow for a first terminal interacting with a cellular network via the N1 interface, including air interface access, registration in the core network, PDU session establishment, resource allocation, tag data reading, and tag data backhaul. It also provides a unique registration method in the core network, two establishment times for the PDU session, and a detailed technical solution for resource allocation. The resource allocation in this application distinguishes between the first terminal and the gNB as the initiator, completing the first terminal role, transmission mode specification, and air interface resource allocation for the first terminal to execute AIoT services. This approach can better adapt to various applications such as automated AIoT services and user-initiated AIoT services. Furthermore, it provides a method for the first terminal to use licensed spectrum for AIoT services, filling the gap in air interface resource allocation between the first terminal and tags in cellular passive IoT systems. This application also specifies two types of first terminal PDUs for executing AIoT services. The session establishment timing can establish AIoT data transmission paths on the core network side as needed, reducing unnecessary session occupation; this application provides a registration method for the first terminal in the core network that is different from the conventional UE registration process. By carrying first information in the registration process to indicate that the first terminal can act as a reader or has reader capability or can perform AIoT services, it is convenient for network devices to allocate subsequent air interface resources.
