[0251] A31. The matching information is used to match or filter target devices;

[0252] A32. The matching information includes information for indicating one or a group of target devices;

[0253] This situation allows for the filtering out of one or a group of target devices.

[0254] A33. The matching information includes information used to indicate all or any target devices;

[0255] This method can filter out all or any target devices.

[0256] Optionally, in one implementation, the first security information includes at least one of A41-A46:

[0257] A41. Message Authentication Code (MAC);

[0264] For example, the target device can store multiple sets of security information, such as at least one of security parameters and security algorithms. Each set of security parameters can be uniquely identified by information used to associate the security parameters or security algorithms; for example, the information used to associate the security parameters or security algorithms can be identification information. When the identification information, for example, is equal to 1, security parameter 1 and security algorithm 1 are associated; when the identification information is equal to 2, security parameter 2 and security algorithm 2 are associated.

[0265] A46. Extensible Authentication Protocol (EAP) container.

[0266] Optionally, in one implementation, the second security information includes at least one of the following:

[0267] MAC;

[0269] Randomly generated strings or bits;

[0270] Information used to derive the key;

[0271] Information used to associate security parameters or security algorithms;

[0272] EAP container.

[0273] Optionally, in one implementation, the first AIoT message and the second AIoT message satisfy at least one of the following:

[0274] The second information of the first AIoT message and the fifth information of the second AIoT message are the same;

[0275] The third information of the first AIoT message is the same as the sixth information of the second AIoT message;

[0276] The first security information of the first AIoT message and the second security information of the second AIoT message are the same.

[0277] Optionally, in one implementation, the first information is used to indicate at least one of the message type and the operation type; specifically, the first information indicates at least one of A501-A509:

[0278] A501, Inventory Operation Request;

[0279] A502, Command Operation Request;

[0280] Optionally, the command operation includes at least one of the following:

[0281] 1) Obtain information from the terminal device;

[0282] 2) Configure information for the terminal device;

[0283] 3) Enable the RF capability of the terminal device;

[0284] 4) Disable the RF capability of the terminal device;

[0288] 2) Operation of obtaining information from the terminal (in one embodiment, the information may be transparent to at least one of the reader and CN device (such as AIoT function)).

[0289] It is easy to understand that when the information is transparent to at least one of the reader / writer and core network devices (such as AIoT functions), there is no need to distinguish between: configuration information sent to the terminal and control commands sent to the terminal. Similarly, there is no need to distinguish between: configuration information sent by the terminal, responses to control commands sent to the terminal, and information read from the terminal device.

[0290] A503, Read operation request;

[0291] Alternatively, in the embodiments of this application, a read operation may also be referred to as a read command.

[0292] A504, Write operation request;

[0293] Alternatively, in the embodiments of this application, a write operation may also be referred to as a write command.

[0294] A505, Activation Operation Request;

[0295] It should be noted that this operation request is used to request the activation of the target device, for example, to activate the target device as a reader / writer.

[0296] A506, Deactivation request;

[0297] It should be noted that this operation request is used to request the deactivation of the target device, for example, to deactivate the target device as a reader / writer, meaning that the target device can no longer be used as a reader / writer.

[0298] A507, Equipment Identification Report Operation Request;

[0299] It should be noted that this operation request is used to request the target device to report its device identifier.

[0300] A508, Operation request to locate the target device;

[0301] A509, Safe Operation Request;

[0302] The security operation is used for at least one of the encryption and integrity protection of the target object between the target device and the first communication device.

[0303] Optionally, A501-A509 mentioned above can be understood as message type, operation type, or both message type and operation type.

[0304] Optionally, in one implementation, the fourth information is used to indicate at least one of the message type and the operation type; specifically, the fourth information indicates at least one of A511-A519:

[0305] A511, Inventory Operation Response;

[0306] A512, Command Operation Response;

[0307] A513, Read Operation Response;

[0308] A514, Write operation response;

[0309] A515, Activation Operation Response;

[0310] A516, Deactivation operation response;

[0311] A517, Equipment Identification Report Operation Response;

[0312] A518. Operational response of the target device;

[0313] A519, Safe Operation Response;

[0314] It should be noted that the second AIoT message is a response message to the first AIoT message. If the first information indicates the operation request, then the fourth information indicates the operation response corresponding to the operation request.

[0315] Optionally, A511-A519 above can be understood as message type, operation type, or both message type and operation type.

[0316] It should also be noted that the command operation, read operation, write operation, control operation, activation operation, and deactivation operation also need to perform at least one of the following: terminal filtering, terminal paging, terminal querying, terminal discovery, terminal identification, terminal authentication, and terminal authorization.

[0317] Optionally, the first information includes: a one-byte information element; or,

[0318] The first information includes two information elements, each of which corresponds to a set of operation types or message types.

[0319] For example, in the case where the first information includes a one-byte information element, the one-byte information element is used to indicate at least one of A501-A518 above.

[0320] For example, when the first information includes two information elements, it can generally be understood that A501-A518 above are divided into two groups, each corresponding to a specific group. For instance, the first information includes information element 1 and information element 2, where information element 1 indicates at least one of: an inventory operation request or a command operation request; information element 2 indicates at least one of: a read operation request, a write operation request, an activation operation request, a deactivation operation request, a notification operation request, a device ID report operation request, a target device location operation request, or a security operation request. It is understood that this implementation can reduce the signaling overhead of the first AIoT message in some cases. For example, when information element 1 indicates an inventory operation request, only information element 1 needs to be carried, without carrying information element 2. Information element 1 contains four possibilities, requiring only 2 bits to indicate (generally, 4 bits can also be used for scalability). In some implementations, the first information element can be 3 bits, and the second information element can be 5 bits, so that information element 1 and information element 2 can reside in the same byte. However, if the first information directly indicates at least one of the following: inventory operation request, command operation request, read operation request, write operation request, activation operation request, deactivation operation request, device identification report operation request, target device location operation request, or security operation request, then 8 bits may be required for indication.

[0321] As an optional implementation, the first AIoT message can be encoded to indicate whether it is for a reader or an AIoT device. For example, the first information is a one-byte information element, where the highest two bits (bits 8 and 7) can be set to "10" to indicate that the AIoT message is for a reader, and set to "01" to indicate that the AIoT message is for an AIoT device. The information indicated by the first information can be encoded from the lower bits (bits 1 to 6) to indicate at least one of the following: inventory operation request, command operation request, read operation request, write operation request, activation operation request, deactivation operation request, notification operation request, device identification report operation request, target device location operation request, and security operation request.

[0322] Optionally, the fourth information may use the same information elements as the first information, that is, the fourth information includes: a one-byte information element; or, the fourth information includes two information elements, each of which corresponds to a set of operation types or message types.

[0323] In some implementations, an AIoT connection exists between an AIoT function and a reader, or between an AIoT function and an AIoT device, to perform AIoT operations (e.g., inventory, writing, reading, etc.). One or more AIoT connections can be used between the same endpoints to support multiple different AIoT operations. Optionally, each AIoT connection is uniquely identified by an AIoT connection identifier (e.g., ID). In some implementations, the second information may include the AIoT connection identifier. It is understood that by carrying the AIoT connection identifier, the AIoT device, upon receiving an inventory operation request message, can determine which AIoT connection the message is for, and thus respond correctly. In this application, an AIoT connection can also be referred to as an AIoT association. In this application, the bearer of the AIoT connection is not limited; for example, the AIoT connection can be carried in a user plane bearer (e.g., a PDU session) or in a NAS message or a NAS message container.

[0324] In some implementations, an AIoT device can execute one or more transactions, where each transaction represents a single AIoT operation performed by the AIoT device (e.g., for a single inventory, write, read, etc.). Transactions can occur consecutively or in parallel. Optionally, a transaction can be identified by a transaction ID. A pair of messages within a transaction are associated using the transaction ID. For example, an inventory operation request message and an inventory operation response message may have the same transaction ID. In some implementations, the transaction ID is unique within the AIoT connection. In some implementations, the transaction ID is unique within the AIoT function. In some implementations, the third information may include the transaction ID. It is understood that by carrying the transaction ID, the reader can determine which transaction the inventory operation response message is for after receiving it, thereby determining the corresponding inventory operation request message for that AIoT transaction, so as to correctly associate the inventory operation request message and the corresponding inventory operation response message. In some implementations, the third information may include identification information for associating AIoT messages (e.g., a correlation ID for associating a pair of AIoT messages). It is understood that two AIoT messages with the same correlation ID are associated.

[0325] In some embodiments, the transaction identifier may also be referred to as the AIoT transaction identifier.

[0326] In some implementations, the relationship between AIoT connections and transactions is shown in Figure 7. An AIoT connection can contain one or more transactions. Transaction identifiers are unique within an AIoT connection, but transaction identifiers can be the same across different AIoT connections. It is understood that an AIoT device may execute multiple AIoT operations serially or in parallel. By carrying at least one of the second and third information, the AIoTF can correctly distinguish which AIoT connection or request message the AIoT device's response corresponds to, thus correctly executing the AIoT operation. It is also understood that the AIoTF can send multiple AIoT operations to an AIoT device simultaneously. By carrying at least one of the second and third information, the AIoTF can correctly distinguish which AIoT connection or request message the AIoT device's response corresponds to, thus correctly executing the AIoT operation.

[0327] It should be noted that, in this embodiment of the application, when the first information indicates a specific operation, the corresponding AIoT message can be referred to as a request message or response message for that specific operation. For example, when the first information indicates an inventory operation request, the AIoT message can be referred to as an inventory operation request message. In this case, the AIoT message and the inventory operation request message express the same meaning. This also applies to other AIoT operations, and will not be elaborated upon here.

[0328] Optionally, based on the first AIoT message, a second AIoT message is sent to the AIoT function, wherein the second AIoT message is a response message to the first AIoT message.

[0329] For example, if the first AIoT message is used to request an inventory operation (in this case, the first AIoT message can be called an inventory operation request message), then the second AIoT message is used to respond to the inventory operation (in this case, the second AIoT message can be called an inventory operation response message); for example, if the first AIoT message is used to request a read operation (in this case, the first AIoT message can be called a read operation request message), then the second AIoT message is used to respond to the read operation (in this case, the second AIoT message can be called a read operation response message); for example, if the first AIoT message is used to request a write operation (in this case, the first AIoT message can be called a write operation request message), then the second AIoT message is used to respond to the write operation (in this case, the second AIoT message can be called a write operation response message); for example, if the first AIoT message is used to request an inventory ... can be called a write operation response message; for example, if the first AIoT message is used to request an inventory operation (in this case, the first AIoT message can be called a write operation request message), then the second AIoT message can be called a write operation response message; for example, if the first AIoT message is used to request an inventory operation (in this case, the first AIoT message can be called a write operation request message), then the second AIoT message can be called a write operation response message; for example, if the first AIoT message is used to request an inventory operation (in this case, the first AIoT message can be called a write operation request message), then the second AIoT message can be called a write operation response message. When an activation operation request is made (in which case the first AIoT message can be referred to as the activation operation request message), the second AIoT message is used to respond to the activation operation (in which case the second AIoT message can be referred to as the activation operation response message); for example, when the first AIoT message is made to make a device identification report operation request (in which case the first AIoT message can be referred to as the device identification report operation request message), the second AIoT message is used to respond to the device identification report operation (in which case the second AIoT message can be referred to as the device identification report operation response message); for example, when the first AIoT message is made to make a security operation request (in which case the first AIoT message can be referred to as the security operation request message), the second AIoT message is used to respond to the security operation (in which case the second AIoT message can be referred to as the security operation response message).

[0330] The specific solutions for different operation requests and operation responses are explained in detail below.

[0331] I. Inventory Count Operation Request and Response

[0332] Typically, the inventory operation request and response are communications between AIoT devices and AIoT functions.

[0333] In this case, the first AIoT message is an inventory operation request message, and the second AIoT message is an inventory operation response message.

[0334] Optionally, when the first information indicates an inventory operation request, the first target load includes at least one of the following:

[0335] B11, Matching Information;

[0336] Optionally, the matching information satisfies at least one of the following: information for matching or filtering AIoT devices; information for indicating one or a group of AIoT devices; or information for indicating all or any AIoT devices.

[0337] B12. Information used to indicate the inventory mode;

[0338] Optionally, the information used to indicate the inventory mode includes at least one of B121 and B122:

[0339] B121. Periodic inventory;

[0340] In some implementations, where the information used to indicate the inventory pattern includes periodic inventory checks, the first target load also includes information indicating the inventory check cycle. For example, the information indicating the inventory check cycle could be every several days, every several hours, every several weeks, every several months, etc.

[0341] B122, An inventory check.

[0342] Understandably, since it is impossible to represent all AIoT devices with a single identifier, the first AIoT message may include information indicating all AIoT devices when an inventory of all AIoT devices is required. When an AIoT device determines that the matching information is appropriate to indicate all AIoT devices, the AIoT device must respond to the first AIoT message, for example, by sending an inventory operation response message (i.e., sending a second AIoT message).

[0343] Optionally, the matching information includes at least one of the following: a complete or partial AIoT device ID; a complete or partial Electronic Product Code (EPC); or a match-all indication. The AIoT device ID refers to an identifier stored in the AIoT device, which can be a permanent identifier or a temporary identifier.

[0344] In some implementations, for example, a warehouse has red and blue goods. The AIoT device might only want to inventory the red goods (identified by the AIoT device installed on them), rather than all goods (i.e., including both red and blue goods). This can be achieved by setting the matching information to red goods, allowing inventory only to be performed on red goods. It is understood that, using the matching information, the AIoT device can determine whether an inventory operation request message needs to be responded to.

[0345] Optionally, in one implementation, when the first information indicates an inventory operation request and the first AIoT message does not contain a first target load, the first AIoT message instructs all or any target devices to respond to the first AIoT message. For example, the first AIoT message instructs all AIoT devices to respond to the first AIoT message.

[0346] Optionally, upon receiving an inventory operation request, the AIoT device determines whether to respond to the inventory operation request message based on the matching information. In some embodiments, if the matching information matches the AIoT device, the AIoT device determines to respond to the inventory operation request message. If the matching information does not match the AIoT device, the AIoT device determines not to respond to the inventory operation request message.

[0347] Optionally, if the first information indicates an inventory operation request and the first AIoT message does not contain the first target load, the AIoT device determines to respond to the inventory operation request message, for example, by sending an inventory operation response message to the reader.

[0348] Optionally, the content of the first format of the first AIoT message under this operation is shown in Table 1:

[0349] Table 1 contains the content of the first format of the first AIoT message.

[0350] Optionally, the content of the second format of the first AIoT message under this operation is shown in Table 2:

[0351] Table 2 contains the content of the second format of the first AIoT message.

[0352] Optionally, the content of the third format of the first AIoT message under this operation is shown in Table 3:

[0353] Table 3 contains the content of the third format of the first AIoT message.

[0354] Optionally, the content of the fourth format of the first AIoT message under this operation is shown in Table 4:

[0355] Table 4 contains the content of the fourth format of the first AIoT message.

[0356] Furthermore, the inventory operation response message is used to respond to the inventory operation request message (i.e., the second AIoT message). After the AIoT device determines that it needs to respond to the inventory operation request message, the AIoT device sends the inventory operation response message.

[0357] Optionally, the inventory operation response message and the inventory operation request message have the same second information.

[0358] Optionally, if the fourth information in the second AIoT message indicates an inventory operation response, the second target payload includes: information for identifying the AIoT device.

[0359] Understandably, by carrying information to identify AIoT devices, the reader can determine which AIoT device responded to the inventory operation request message.

[0360] Optionally, the content of the first format of the second AIoT message under this operation is shown in Table 5:

[0361] Table 5 contains the content of the first format of the second AIoT message.

[0362] Optionally, the content of the second format of the second AIoT message under this operation is shown in Table 6:

[0363] Table 6 contains the content of the second format of the second AIoT message.

[0364] Optionally, the content of the third format of the second AIoT message under this operation is shown in Table 7:

[0365] Table 7 contains the content of the third format of the second AIoT message.

[0366] Optionally, the content of the fourth format of the second AIoT message under this operation is shown in Table 8:

[0367] Table 8 contains the content of the fourth format of the second AIoT message.

[0368] It should also be noted that the inventory operation response message can also be called the inventory operation acceptance message, inventory report message, inventory result message, or inventory operation success message.

[0369] II. Read Operation Requests and Read Operation Responses

[0370] Typically, read operation requests and read operation responses are communication between AIoT devices and AIoT functions.

[0371] In this case, the first AIoT message is a read operation request message, and the second AIoT message is a read operation response message.

[0372] Optionally, if the first information indicates a read operation request, the first target payload includes at least one of B21-B26:

[0373] B21. Matching information;

[0374] B22. Information used to indicate the starting field of a read operation;

[0375] For example, it can be the memory start address.

[0376] B23. Information used to indicate the termination field of a read operation;

[0377] For example, it can be the memory end address.

[0378] B24. Information used to indicate the length of the read operation field;

[0379] For example, it can be the memory read length.

[0380] B25. Information used to identify paragraph positions;

[0381] For example, it can be a segment address.

[0382] B26. Information used to indicate paragraph size;

[0383] For example, it could be the segment size.

[0384] It should be noted that the matching information can be found in the above description and will not be repeated here; through the matching information, the AIoT device can determine whether it needs to respond to the read operation request.

[0385] In some implementations, AIoT devices have memory cells. Each memory cell can store one byte of data. Information in the start field, indicating the beginning of a read operation, allows the AIoT device to determine where within the memory cell the data needs to be read. The start field can be the memory address information of the storage cell; for example, if data from 0x00000002 to 0x00000008 needs to be read, the start field is set to 0x00000002.

[0386] In some implementations, AIoT devices have memory cells. Each memory cell can store one byte of data. Information in a termination field indicates where the AIoT device needs to terminate the data read operation within the memory cell. The termination field can be the memory address information of the storage cell; for example, if data from 0x00000002 to 0x00000008 needs to be read, the termination field is set to 0x00000008.

[0387] In some implementations, the AIoT device has memory cells. Each memory cell can store one byte of data. By combining information in a start field indicating the start of a read operation and information in a field indicating the length of the read operation, the AIoT device can determine where in the memory cell the data read operation needs to terminate. For example, when reading data from 0x00000002 to 0x00000008, the start field of the read operation is set to 0x00000002, and the field length of the read operation can be set to 7. In some implementations, the unit of the field length of the read operation is bytes.

[0388] In some implementations, AIoT devices have memory units. Each memory unit can store one byte of data. The AIoT device can divide the memory into different segments, each segment containing several memory units, allowing access and manipulation on a segment-by-segment basis. For example, the AIoT device can divide the memory segment sizes into 1KB, 4KB, 64KB, etc. Using information to identify the segment position, the AIoT device can determine which segment to perform a read operation on. For example, when the segment identification information is set to 3, the AIoT device reads the third segment from the start field of the memory.

[0389] In some implementations, the AIoT device can determine the size of a paragraph using information indicating the paragraph size. For example, the paragraph size can be 1KB, 4KB, or 64KB. In some implementations, setting the information indicating the paragraph size to 4 indicates a paragraph size of 4KB. It is understood that by combining the information indicating the paragraph size with the information identifying the paragraph's location, the AIoT device can correctly read the corresponding paragraph from memory.

[0390] Optionally, when the first information indicates a read operation request and the first target payload contains only matching information, the first AIoT message indicates reading all data from the target AIoT device. For example, the first AIoT message indicates reading all data from the AIoT device.

[0391] Optionally, after receiving a read operation request, the AIoT device determines whether to respond to the read operation request message based on the matching information. In some embodiments, if the matching information matches the AIoT device, the AIoT device determines to respond to the read operation request message. If the matching information does not match the AIoT device, the AIoT device determines not to respond to the read operation request message.

[0392] Optionally, the content of the first format of the first AIoT message under this operation is shown in Table 9:

[0393] Table 9 contains the content of the first format of the first AIoT message.

[0394] Optionally, the content of the second format of the first AIoT message under this operation is shown in Table 10:

[0395] Table 10 contains the content of the second format of the first AIoT message.

[0396] Optionally, the content of the third format of the first AIoT message under this operation is shown in Table 11:

[0397] Table 11 contains the content of the third format of the first AIoT message.

[0398] The read operation response message is used to respond to the read operation request message. After the AIoT device determines that it needs to respond to the read operation request message, the AIoT device sends a read operation response message.

[0399] Optionally, the read operation response message and the read operation request message have the same second information.

[0400] Optionally, when the fourth information in the read operation response message indicates a read operation response, the second target payload of the read operation response message includes at least one of the following: information indicating whether the read operation was successful or unsuccessful; read operation target information; information for identifying the AIoT device; information indicating the reason for the unsuccessful read operation; and a first timer, after which the AIoT device can receive a read operation request again.

[0401] It is understandable that information indicating the success or failure of a read operation allows the reader and AIoTF to know whether the AIoT device successfully executed the read operation request message. In some implementations, the information indicating the success or failure of a read operation can be an implicit indication, such as the message name. For example, in the case of a successful read operation, the AIoT device sends a read operation success message or a read operation acceptance message; in the case of an unsuccessful read operation, the AIoT device sends a read operation failure message or a read operation rejection message. In some implementations, the information indicating the success or failure of a read operation can be bit indication information, for example, a bit indication of 1 indicates success, and a bit indication of 0 indicates failure. In some implementations, the information indicating the success or failure of a read operation can be first information.

[0402] Understandably, by carrying information to identify AIoT devices, readers can determine which AIoT device responded to the read operation request message.

[0403] It is understood that the target information for the read operation is the information read by the AIoT device during the read operation. This corresponds to the information carried in the read operation request, including the start field indicating the read operation, the end field indicating the read operation, the length of the read operation field, the paragraph position identifier, and the paragraph size. In other words, if the read operation request requires reading data from 0x00000002 to 0x00000008, then the target information for the read operation is the data from 0x00000002 to 0x00000008 in the AIoT device.

[0404] It is understandable that, in cases where the information used to indicate a successful or unsuccessful read operation indicates failure, the AIoT device can carry information indicating the reason for the read operation's failure. In some implementations, the information indicating the reason for the read operation's failure is a reason value.

[0405] Optionally, the information used to indicate the reason for the unsuccessful read operation indicates at least one of the following: the operation is not allowed; the operation cannot be performed temporarily; security failure; security information mismatch.

[0406] In some implementations, the AIoT device may be configured, for example, to allow only write operations, thus preventing it from reading data. In this case, information indicating the reason for the unsuccessful read operation can indicate that the operation is not allowed. Upon receiving information indicating that the read operation is not allowed, the reader will not send another read operation request message to the AIoT device.

[0407] In some implementations, AIoT devices may be limited in their capabilities; for example, an AIoT device may only support a limited number of AIoT operations and therefore be unable to perform more. In such cases, information indicating the reason for a failed read operation can indicate that the operation is temporarily unavailable. Upon receiving information indicating that the operation is temporarily unavailable, the reader can resend a read operation request message to the AIoT device after a period of time.

[0408] In some implementations, read operation request messages may carry security information. An AIoT device may be unable to execute a corresponding read command, i.e., unable to read data, due to security reasons such as security information check failure or security information mismatch. In this case, the information indicating the reason for the unsuccessful read operation can indicate security failure or security information mismatch. Upon receiving information indicating security failure or security information mismatch, the reader can notify the network side, such as the Access and Mobility Management Function (AMF) or AIoTF. Before the security information is updated, the reader may not initiate any further operation request messages, such as read operation request messages or write request messages, to the AIoT device. The reader may also update the security information of the AIoT device.

[0409] Optionally, the content of the first format of the second AIoT message under this operation is shown in Table 12:

[0410] Table 12 contains the content of the first format of the second AIoT message.

[0411] Optionally, the content of the second format of the second AIoT message under this operation is shown in Table 13:

[0412] Table 13 contains the content of the second format of the second AIoT message.

[0413] Optionally, the content of the third format of the second AIoT message under this operation is shown in Table 14:

[0414] Table 14 contains the content of the third format of the second AIoT message.

[0415] Optionally, the content of the fourth format of the second AIoT message under this operation is shown in Table 15:

[0416] Table 15 contains the content of the fourth format of the second AIoT message.

[0417] Optionally, the content of the fifth format of the second AIoT message under this operation is shown in Table 16:

[0418] Table 16 contains the content of the fifth format of the second AIoT message.

[0419] Optionally, the content of the sixth format of the second AIoT message under this operation is shown in Table 17:

[0420] Table 17 contains the content of the sixth format of the second AIoT message.

[0421] Optionally, the content of the seventh format of the second AIoT message under this operation is shown in Table 18:

[0422] Table 18 contains the content of the seventh format of the second AIoT message.

[0423] III. Write Operation Request and Write Operation Response

[0424] Typically, write operation requests and write operation responses are communication between AIoT devices and AIoT functions.

[0425] In this case, the first AIoT message is a write operation request message, and the second AIoT message is a write operation response message.

[0426] Optionally, when the first information in the first AIoT message indicates a write operation request, the first target payload of the first AIoT message includes at least one of the following: matching information; information for indicating the start field of the write operation; information for indicating the end field of the write operation; information for indicating the length of the write operation field; information for identifying the paragraph position; information for indicating the paragraph size; and write operation target information.

[0427] The matching information is as described above and will not be repeated here; through the matching information, the AIoT device can determine whether it needs to respond to the write operation request.

[0428] In some implementations, AIoT devices have memory cells. Each memory cell can store one byte of data. Information in the start field, indicating the beginning of a write operation, allows the AIoT device to determine where within the memory cell the data needs to be written. The start field can be the memory address information of the storage cell; for example, if data between 0x00000002 and 0x00000008 needs to be written, the start field is set to 0x00000002.

[0429] In some implementations, AIoT devices have memory cells. Each memory cell can store one byte of data. Information in a termination field indicates where the AIoT device needs to terminate the write operation within the memory cell. The termination field can be the memory address information of the storage cell; for example, if data from 0x00000002 to 0x00000008 needs to be written, the termination field is set to 0x00000008.

[0430] In some implementations, the AIoT device has memory cells. Each memory cell can store one byte of data. By combining information in a start field indicating the beginning of a write operation and information in a field indicating the length of the write operation, the AIoT device can determine where in the memory cell the write operation needs to terminate. For example, when writing data from 0x00000002 to 0x00000008, the start field of the write operation is set to 0x00000002, and the field length of the write operation can be set to 7. In some implementations, the unit of the field length of the write operation is bytes.

[0431] In some implementations, AIoT devices have memory units. Each memory unit can store one byte of data. The AIoT device can divide the memory into different segments, each segment containing several memory units, allowing access and manipulation on a segment-by-segment basis. For example, the AIoT device can divide the memory segment sizes into 1KB, 4KB, 64KB, etc. Using information to identify the segment position, the AIoT device can determine which segment to perform a write operation on. For example, when the segment identification information is set to 3, it indicates that the AIoT device is writing data to the third segment starting from the beginning of the memory.

[0432] In some implementations, the AIoT device can determine the size of a paragraph using information indicating the paragraph size. For example, the paragraph size can be 1KB, 4KB, or 64KB. In some implementations, setting the information indicating the paragraph size to 4 indicates a paragraph size of 4KB. It is understood that by combining the information indicating the paragraph size with the information identifying the paragraph's location, the AIoT device can correctly write the corresponding paragraph into memory.

[0433] It is understood that the write operation target information is the information that the AIoT device needs to write to perform a write operation. This corresponds to the information carried in the write operation request, including the information indicating the start field, the end field, the length of the write field, the paragraph position, and the paragraph size. In other words, if the write operation request requires writing data from 0x00000002 to 0x00000008, then the write operation target information is the data information from 0x00000002 to 0x00000008 in the AIoT device.

[0434] Optionally, if the first target payload contains only matching information, the first AIoT message indicates that all data of the target device should be written or overwritten. For example, the first AIoT message indicates that all data of the AIoT device should be written or overwritten.

[0435] Optionally, upon receiving a write operation request, the AIoT device determines whether to respond to the write operation request message based on the matching information. In some embodiments, if the matching information matches the AIoT device, the AIoT device determines to respond to the write operation request message. If the matching information does not match the AIoT device, the AIoT device determines not to respond to the write request message.

[0436] Optionally, the content of the first format of the first AIoT message under this operation is shown in Table 19:

[0437] Table 19 Contents of the First Format of the First AIoT Message

[0438] Optionally, the content of the second format of the first AIoT message under this operation is shown in Table 20:

[0439] Table 20 contains the content of the second format of the first AIoT message.

[0440] Optionally, the content of the third format of the first AIoT message under this operation is shown in Table 21:

[0441] Table 21 contains the content of the third format of the first AIoT message.

[0442] The write operation response message is used to respond to the write operation request message. After the AIoT device determines that it needs to respond to the write operation request message, the AIoT device sends a write operation response message.

[0443] Optionally, the write operation response message and the write operation request message have the same second information.

[0444] Optionally, when the fourth information in the write operation response message indicates a write operation response, the second target payload of the write operation response message includes at least one of the following: information indicating whether the write operation was successful or unsuccessful; information identifying the AIoT device; information indicating the reason for the write operation failure; and a second timer, after which the AIoT device can receive a write operation request message again.

[0445] Understandably, information indicating the success or failure of a write operation allows the reader and AIoTF to know whether the AIoT device successfully executed the write operation request message. In some implementations, the information indicating the success or failure of a write operation can be implicit, such as the message name. For example, in the case of a successful write operation, the AIoT device sends a write operation success message or a write operation acceptance message; in the case of an unsuccessful write operation, the AIoT device sends a write operation failure message or a write operation rejection message. In some implementations, the information indicating the success or failure of a write operation can be bit indication information, for example, a bit indication of 1 indicates success, and a bit indication of 0 indicates failure. In some implementations, the information indicating the success or failure of a write operation can be first information.

[0446] Understandably, by carrying information to identify AIoT devices, the reader can determine which AIoT device responded to the write operation request message.

[0447] Understandably, if the information used to indicate a successful or unsuccessful write operation indicates failure, the AIoT device can carry information indicating the reason for the write operation's failure. In some implementations, the information indicating the reason for the write operation's failure is a reason value.

[0448] Optionally, the information used to indicate the reason for the unsuccessful write operation indicates at least one of the following: operation is not allowed; operation cannot be performed temporarily; data write error; write address error; security failure; security information mismatch.

[0449] In some implementations, the AIoT device may be configured, for example, to be read-only, thus preventing it from writing data. In this case, information indicating the reason for the unsuccessful read operation can indicate that the operation is not allowed. Upon receiving information indicating that the write operation is not allowed, the reader will not send another write operation request message to the AIoT device.

[0450] In some implementations, AIoT devices may be limited in their capabilities; for example, an AIoT device may only support a limited number of AIoT operations and therefore be unable to perform more. In such cases, information indicating the reason for a failed read operation can indicate that the operation is temporarily unavailable. Upon receiving information indicating that the operation is temporarily unavailable, the reader can resend a write operation request message to the AIoT device after a period of time.

[0451] In some implementations, the address information written (e.g., information indicating the start field of the write operation; information indicating the end field of the write operation; information indicating the length of the write operation field; information identifying the paragraph position; information indicating the paragraph size) may not match the data being written. For example, the target information for the write operation may be data from 0x00000002 to 0x00000008 in the AIoT device, but the provided target information does not match the length of 0x00000002 to 0x00000008 (e.g., exceeding or falling short of the written address information). The AIoT device may indicate a write data error. Upon receiving information indicating a write data error due to a failed read operation, the reader can resend a write operation request message to the AIoT device, carrying the correct write data.

[0452] In some implementations, the address information written (e.g., information indicating the start field of the write operation; information indicating the end field of the write operation; information indicating the length of the write operation field; information identifying the paragraph position; information indicating the paragraph size) may not match the data being written. For example, the target information for the write operation may be data from 0xFFFFFFF2 to 0xFFFFFFF6 in the AIoT device, but the AIoT device does not have such memory address information (e.g., the memory range of the AIoT device is 0x00000000 to 0x0000000F). In this case, the AIoT device may indicate a write address error. Upon receiving information indicating a write address error to explain the reason for the unsuccessful read operation, the reader can resend a write operation request message to the AIoT device, carrying the correct write address.

[0453] In some implementations, the write operation request message may carry first security information. An AIoT device may be unable to execute the corresponding write command operation (i.e., unable to write data) due to security reasons, such as security information check failure or security information mismatch. In this case, the information indicating the reason for the write operation failure may indicate security failure or security information mismatch. Upon receiving information indicating security failure or security information mismatch, the reader can notify the network side, such as the AMF or AIoTF. Before the security information is updated, the reader may not initiate any further operation request messages, such as read operation request messages or write request messages, to the AIoT device. The reader may also update the security information of the AIoT device.

[0454] Optionally, the content of the first format of the second AIoT message under this operation is shown in Table 22:

[0455] Table 22 Contents of the First Format of the Second AIoT Message

[0456] Optionally, the content of the second format of the second AIoT message under this operation is shown in Table 23:

[0457] Table 23 contains the content of the second format of the second AIoT message.

[0458] Optionally, the content of the third format of the second AIoT message under this operation is shown in Table 24:

[0459] Table 24 contains the content of the third format of the second AIoT message.

[0460] Optionally, the content of the fourth format of the second AIoT message under this operation is shown in Table 25:

[0461] Table 25 contains the content of the fourth format of the second AIoT message.

[0462] Optionally, the content of the fifth format of the second AIoT message under this operation is shown in Table 26:

[0463] Table 26 lists the contents of the fifth format of the second AIoT message.

[0464] Optionally, the content of the sixth format of the second AIoT message under this operation is shown in Table 27:

[0465] Table 27 contains the content of the sixth format of the second AIoT message.

[0466] IV. Activation Request and Activation Response

[0467] In this case, the first AIoT message is an activation operation request message, and the second AIoT message is an activation operation response message.

[0468] Typically, the activation request and response constitute communication between the reader / writer and the AIoT function. That is, the activation request is used to activate the terminal as a reader / writer. In some implementations, the network side sends the activation request message to the terminal (reader / writer) after authorizing it to function as a reader / writer. In other implementations, the network side sends the activation request message to the terminal (reader / writer) after allocating resources for it to function as a reader / writer.

[0469] Optionally, if the first information of the activation operation request message indicates an activation operation request, the first target payload of the activation operation request message includes: matching information; valid time; and valid region.

[0470] The matching information is as described above and will not be repeated here. Using the matching information, the reader / writer can determine whether an activation request needs to be responded to.

[0471] Upon receiving an activation request and if the matching information matches the reader / writer, the reader / writer is determined to be activated as a reader / writer.

[0472] It is understood that by carrying a validity period, the effective time for which the device is activated as a reader / writer can be indicated. In some implementations, the validity period may include a start time and an end time, or it may be a duration. For example, setting the validity period to 10 hours means that the device is activated as a reader / writer within 10 hours of receiving the activation request. The validity period may include default unit information, such as minutes, hours, days, weeks, months, or years. In some implementations, not carrying a validity period can be understood as having no time limit.

[0473] It is understood that by carrying a valid area, the active area for the reader / writer can be indicated. In some implementations, the valid area can be a tracking area (TA), a cell, a registration area (RA), or all areas. In some implementations, not carrying a valid area can be understood as having no restriction on the area.

[0474] Optionally, the content of the first format of the first AIoT message under this operation is shown in Table 28:

[0475] Table 28 Contents of the First Format of the First AIoT Message

[0476] Optionally, the content of the second format of the first AIoT message under this operation is shown in Table 29:

[0477] Table 29 contains the content of the second format of the first AIoT message.

[0478] The activation operation response message is used to respond to the activation operation request message. After the AIoT device determines that it needs to respond to the activation operation request message, the AIoT device sends the activation operation response message.

[0479] Optionally, the activation operation response message and the activation operation request message have the same second information.

[0480] Optionally, when the fourth information indicates an activation operation response, the second target payload includes at least one of the following: information indicating whether the activation operation was successful or unsuccessful; information indicating the reason for the activation operation's failure.

[0481] Optionally, the information used to indicate the reason for the unsuccessful activation operation indicates at least one of the following: operation is not allowed; time is not allowed; area is not allowed; security failure; security information mismatch.

[0482] It is understandable that information indicating the success or failure of the activation operation allows the AIoTF to know whether the reader / writer successfully executed the activation request message. In some implementations, the information indicating the success or failure of the activation operation can be implicit, such as the message name. For example, in the case of a successful activation operation, the AIoT device sends an activation success message or an activation acceptance message; in the case of an unsuccessful activation operation, the AIoT device sends an activation failure message or an activation rejection message. In some implementations, the information indicating the success or failure of the activation operation can be bit indication information, for example, a bit indication of 1 indicates success, and a bit indication of 0 indicates failure. In some implementations, the information indicating the success or failure of the activation operation can be first information.

[0483] It is understandable that, if the information used to indicate success or failure of the activation operation indicates failure, the AIoT device can carry information indicating the reason for the activation operation's failure. In some implementations, the information used to indicate the reason for the activation operation's failure is a reason value.

[0484] In some implementations, the reader may be partially disabled due to settings, such as the reader's functional modules being turned off. In this case, information indicating the reason for the unsuccessful activation operation can indicate that the operation is not allowed.

[0485] In some implementations, the reader may fail to activate because the user refuses to become the reader. In this case, the information indicating the reason for the unsuccessful activation operation can indicate that the operation is not allowed.

[0486] In some implementations, if the activation request message contains area information and the reader is in an unallowed area, the information used to indicate the reason for the unsuccessful activation operation can indicate that the area is not allowed.

[0487] In some implementations, the activation request may carry security information. The reader / writer may be unable to perform the corresponding activation operation (i.e., activation fails) due to security reasons, such as security information check failure or security information mismatch. In this case, the information indicating the reason for the activation failure may indicate security failure or security information mismatch. Upon receiving information indicating security failure or security information mismatch, the reader / writer can notify the network side, such as AMF or AIoTF. Until the security information is updated, the reader / writer may not initiate any further AIoT operation request messages to the AIoT device.

[0488] Optionally, the content of the first format of the second AIoT message under this operation is shown in Table 30:

[0489] Table 30 contains the content of the first format of the second AIoT message.

[0490] Optionally, the content of the second format of the second AIoT message under this operation is shown in Table 31:

[0491] Table 31 contains the content of the second format of the second AIoT message.

[0492] V. Equipment Identification Report Operation Request and Equipment Identification Report Operation Response

[0493] Optionally, the Device Identification Report Operation Request is used to obtain the AIoT device identifier of the AIoT device.

[0494] In this case, the first AIoT message is a device identification report operation request message, and the second AIoT message is a device identification report operation response message.

[0495] Optionally, if the first information in the device identification report operation request message indicates a device identification report operation request, the first target payload of the device identification report operation request message includes: matching information.

[0496] The matching information is as described above and will not be repeated here. Using the matching information, the AIoT device can determine whether it needs to respond to a device identification report operation request.

[0497] Upon receiving a device identification report operation request, and if the matching information matches the AIoT device, the AIoT device determines the reporting device identification.

[0498] Optionally, the content of the first format of the first AIoT message under this operation is shown in Table 32:

[0499] Table 32 Contents of the First Format of the First AIoT Message

[0500] Optionally, the content of the second format of the first AIoT message under this operation is shown in Table 33:

[0502] Optionally, the content of the third format of the first AIoT message under this operation is shown in Table 34:

[0503] Table 34 contains the content of the third format of the first AIoT message.

[0504] The Device Identification Report Operation Response Message is used to respond to the Device Identification Report Operation Request Message. After determining that it needs to respond to the Device Identification Report Operation Request Message, the AIoT device sends the Device Identification Report Operation Response Message.

[0505] Optionally, the Device Identification Report Operation Response Message and the Device Identification Report Operation Request Message have the same second information.

[0506] Optionally, in the case where the fourth information indicates that the device identifier reports an operational response, the second target payload includes: the AIoT device identifier.

[0507] Optionally, the content of the first format of the second AIoT message under this operation is shown in Table 35:

[0508] Table 35 contains the content of the first format of the second AIoT message.
