Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0052] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0053] With the widespread application of IoT technology in the field of wireless communications, the functionality and battery life of IoT devices have become the focus of attention. In order to reduce the size, complexity, power consumption and other performance of IoT devices, environmental IoT has received widespread attention from industry and academia in recent years.

[0054] AIoT devices are devices that do not require power or have power storage capabilities. AIoT devices can obtain energy from the environment and transmit data signals through backscattering and low-power radio frequency transmission. AIoT devices have the characteristics of ultra-low power consumption, ultra-low cost, and extremely small terminal size. They are used in various asset inventory, sensor collection, rough positioning of objects / personnel, etc., empowering warehousing, logistics, transportation, medical care, home and other industries to realize the interconnection of all things.

[0055] Currently, 3GPP is conducting research on 5G network support for IoT devices, and proposed an enhanced 5GC architecture in the TR23.700-13 standard to support AIoT device management and AIoT services. A new AIoTMF network element is added to the 5GC architecture to process AIoT services. The AIoTMF network element can replace the access and mobility management function (AMF) network element or be combined with the AMF network element. The AIoTMF network element communicates with the access network equipment, and the access network equipment communicates with the AIoT device.

[0056] Specifically, the enhanced 5GC architecture includes unified data management (UDM) network elements, authentication server function (AUSF) network elements, network exposure function (NEF) network elements, application function (AF) network elements, charging function (CHF) network elements and AIoTMF network elements jointly established with AMF network elements.

[0057] Depending on the operator's policy, the disabling of the RF transmission function may be temporary or permanent, so it is critical to ensure that the disabling operation (especially permanent disabling) is performed safely. However, in the standard TR 33.713, the environmental IoT management function network element sends a disabling command to disable the function of the environmental IoT device to transmit RF signals.

[0058] like Figure 1 As shown, the following specifically introduces the process of disabling the function of transmitting radio frequency signals of environmental IoT devices through steps 1 to 8.

[0059] Step 1: The AIoTMF network element sends a temporary disabling command to the access network device. Correspondingly, the access network device receives the temporary disabling command. The temporary disabling command includes a first timer, which represents the sending time of the temporary disabling command.

[0060] Step 2: The access network device sends a temporary disabling command to the AIoT device. Correspondingly, the AIoT device receives the temporary disabling command.

[0061] Step 3: The AIoT device saves the first timer in the temporary disable command.

[0062] Step 4: The AIoT device sends a response message. Correspondingly, the access network device receives the response message. The response message includes the first timer.

[0063] Step 5: The access network device sends a response message. Correspondingly, the AIoTMF network element receives the response message.

[0064] Step 6: The AIoTMF network element sends a permanent disable command. Correspondingly, the access network device receives the permanent disable command.

[0065] Step 7: The access network device sends a permanent disable command. Correspondingly, the AIoT device receives the permanent disable command.

[0066] Step 8. The AIoT device saves the second timer in the permanent disable command and verifies whether the preset conditions are met; if so, the RF transmission function is permanently disabled.

[0067] The preset conditions include: whether the radio frequency transmission function of the AIoT device is temporarily turned off; whether the time difference between the second timer and the first timer is greater than or equal to the pre-configured threshold of the AIoT device.

[0068] In the above steps, the AIoT device communicates with the AIoTMF network element through the access network device. The disable command sent from the environmental Internet of Things management function network element in the core network is transmitted in plain text during the communication process between the AIoT device and the access network device and the communication process between the access network device and the AIoTMF network element. However, the related art does not perform encryption protection for the disable command, and there is a risk of being easily attacked or eavesdropped, resulting in the AIoT device being unable to receive the correct command or performing the wrong operation. It can be seen that in the process of the AIoT device communicating with the AIoTMF network element through the access network device, there is a problem of poor security in transmitting the disable command.

[0069] In addition, after receiving a disable command, the AIoT device cannot verify whether the command comes from a trusted party, and the result of the AIoT device executing the disable command is not fed back to the core network.

[0070] In view of this, the device disabling method provided by the present application, the second node sends a first message. Correspondingly, the first node receives the first message. Furthermore, the first node performs XOR decryption on the first disabling command based on a random number to determine the first numerical value, and sends a first indication message for instructing the first node to permanently disable or permanently inactivate the radio frequency transmission function when the first numerical value meets the first verification condition. Correspondingly, the second node receives the first indication message to determine the result of the first node executing the disabling command. Since the first message in the above technical solution includes the first disabling command, and the first disabling command is a disabling command determined by XOR-encrypting the first numerical value of the second disabling command at the first preset position with the random number. Therefore, the above technical solution can solve the problem of poor transmission security of the disabling command currently sent by the AIoTMF network element, and greatly improves the security of the disabling command during transmission.

[0071] The implementation of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

For example, "disable command" can be replaced by "inactivate command".

[0105] In some possible implementations, the second disabling command may be a disabling command consisting of a number of the first preset number of digits. The random number may be a random number consisting of a number of the second preset number of digits. The number may be a decimal number, a binary number, or a hexadecimal number. Of course, the above is only an exemplary description of the number system, and the number may also be in other systems, and the present application does not impose any limitation on this.

[0106] The second preset number of bits is determined according to the first preset number of bits. For example, when the first preset number of bits is 32 bits, the second preset number of bits can be determined to be 16 bits. For another example, when the first preset number of bits is 8 bits, the second preset number of bits can be determined to be 4 bits.

[0107] Furthermore, the second preset number of digits is the same as the number of digits corresponding to the first preset position. For example, when the first preset position is 0-15, the second preset number of digits is 16. For another example, when the first preset position is 0-3, the second preset number of digits is 4.

[0108] Optional, such as Figure 5As shown, the second disabling command may be a disabling command composed of 32 binary digits (eg, 01000101010011111100011011001111). Taking the first preset position as 0-15 as an example, the first value is 0100010101001111.

[0109] Optionally, the second disabling command may be a disabling command consisting of 8 decimal digits, for example, 85893869. Taking the first preset position as 0-3 as an example, the first value is 8589.

[0110] Optionally, the random number may be a random number consisting of 16 binary digits, or a random number consisting of 4 decimal digits.

[0111] The following describes the process of performing XOR encryption on different types of first numerical values ​​and different types of random numbers to determine the first disabling command through Examples 1 to 3.

[0112] Example 1 specifically introduces the process of determining the first disable command based on the first numerical value composed of binary digits and the random number composed of binary digits; Example 2 specifically introduces the process of determining the first disable command based on the first numerical value composed of decimal digits and the random number composed of decimal digits; Example 3 specifically introduces the process of determining the first disable command based on the first numerical value composed of binary digits and the random number composed of decimal digits; Example 4 specifically introduces the process of determining the first disable command based on the first numerical value composed of decimal digits and the random number composed of binary digits.

[0113] Example 1: When the first value is 0100010101001111 composed of binary numbers and the random number is 00110101010101001 composed of binary numbers, the first value composed of binary numbers and the random number composed of binary numbers are XOR-encrypted to obtain a first disabling command.

[0114] Example 2: When the first value is 8589 in decimal format and the random number is 3569 in decimal format, the first value 8589 is represented by binary digits as 0100010101001001. The random number 3569 is represented by binary digits as 0011010101101001. Furthermore, the first value converted into binary digits is XOR-encrypted with the random number converted into binary digits to obtain a first disable command.

[0115] It should be noted that 8 is represented by 0100 in binary, 5 is represented by 0101 in binary, 9 is represented by 1001 in binary, 3 is represented by 0011 in binary, and 6 is represented by 0110 in binary.

[0116] Example 3: When the first value is 0100010101001111 composed of binary numbers and the random number is 3569 composed of decimal numbers, the random number 3569 is represented by binary numbers as 0011010101101001. Then, the first value composed of binary numbers and the random number converted into a binary value are XOR-encrypted to obtain a first disable command.

[0117] Example 4: When the first value is 8589 in decimal format and the random number is 0011010101101001 in binary format, the first value 8589 is represented by binary digits as 0100010101001001. Then, the first value converted into binary digits is XOR-encrypted with the random number composed of binary digits to obtain a first disable command.

[0118] The process of determining the first disabling command is described in detail above.

[0119] In a possible implementation, the implementation process of S401 may be: the environment Internet of Things management function network element (i.e., the second node) sends a first message to the access network device. Accordingly, the access network device receives the first message. The access network device sends the first message to the environment Internet of Things device (i.e., the first node). Accordingly, the environment Internet of Things device receives the first message.

[0120] Furthermore, in some possible implementations, the access network device may send the first message to the environmental IoT device by transparent transmission. Alternatively, the access network device may send the first message to the environmental IoT device by relay transmission. Alternatively, the access network device may send the first message to the environmental IoT device by encrypted transmission.

[0121] Of course, the above is only an exemplary description of transmitting the first message. The implementation process of transmitting the first message can also be implemented through other transmission methods in the future, and the embodiments of the present application do not impose any restrictions on this.

[0122] It can be understood that the first message is information determined after XOR encryption. Therefore, the access network device can still ensure the security of data transmission by sending the first message to the environmental Internet of Things device through transparent transmission, wireless transparent transmission or relay transmission.

[0123] In another possible implementation method, the implementation process of S401 can also be: there is a communication link that can directly communicate between the environmental Internet of Things management function network element (i.e., the second node) and the environmental Internet of Things device (i.e., the first node), and the environmental Internet of Things management function network element can send a first message to the environmental Internet of Things device through the direct communication link without the need for information transfer through the access network device.

[0124] S402: The first node performs XOR decryption on the first disabling command based on the random number to determine a first value.

[0125] In a possible implementation, S402 may be implemented as follows: when the first disabling command and the random number are both random numbers consisting of binary numbers with a second preset number of bits, performing an XOR decryption operation on the first disabling command and the random number to obtain a first value.

[0126] In another possible implementation method, S402 can also be implemented as follows: when the first disabling command and the random number are both random numbers consisting of decimal numbers with a second preset number of bits, the first disabling command and the random number are both converted into binary numbers, and then the first disabling command converted into binary numbers and the random number converted into binary numbers are subjected to an XOR decryption operation to obtain a first value.

[0127] In another possible implementation method, S402 can also be implemented as follows: when the first disabling command is a disabling command consisting of a 4-bit decimal number and the random number is a random number consisting of a 16-bit binary number, the first disabling command is converted into a disabling command of a 16-bit binary number, and then, the first disabling command converted into a 16-bit binary number is subjected to an XOR decryption operation with the random number consisting of the 16-bit binary number to obtain a first value.

[0128] In another possible implementation method, S402 can also be implemented as follows: when the first disabling command is a disabling command composed of a 16-bit binary number and the random number is a random number composed of a 4-digit decimal number, the random number is converted into a 16-bit binary number, and then, the first disabling command composed of the 16-bit binary number is subjected to an XOR decryption operation with the random number converted to a 16-bit binary number to obtain a first value.

[0129] S403: When the first value satisfies the first verification condition, the first node sends first indication information. Correspondingly, the second node receives the first indication information.

[0130] The first indication information is used to instruct the first node to permanently disable or permanently inactivate the radio frequency transmission function.

[0131] Optionally, the first verification condition includes: after the first value and the second value are combined, they are the same as a preset disabling command.

[0132] For example, Figure 5 As shown, the second value is the value of the second disable command at the second preset position. For example, taking the second disable command as 01000101010011111100011011001111, and the second preset position as 16-31 bits as an example, the second value is 1100011011001111. For another example, taking the second disable command as 85893869, and the second preset position as 4-7 bits as an example, the second value is 3869.

[0133] It is understandable that by verifying whether the first value and the second value are the same as the preset disable command after being combined, it is possible to determine whether the attribute of the first disable command received by the first node is a disable command, and it is also possible to verify whether the disable command is a disable command issued to the first node, thereby avoiding the situation where the first node mistakenly responds to the disable command of other devices. Compared with the current environment where IoT devices cannot verify whether the disable command comes from a trusted party after receiving the disable command, the above technical solution verifies the first disable command through the first verification condition, greatly improving the security and reliability of disabling the first node.

[0134] Optionally, the first verification condition may include: verifying whether the first value is the same as a fourth value of a preset disabling command at a fourth preset position.

[0135] It can be understood that, when the first node has verified the second value, only the first value needs to be verified, thereby reducing the waste of computing resources.

[0136] Optionally, when the first message also includes a first timer and the second message also includes a second timer, the first verification condition also includes at least one of the following: the radio frequency transmission function has been temporarily disabled or temporarily deactivated; or, the time difference between the first timer and the second timer is greater than or equal to a preset duration.

[0137] It should be noted that, when the time difference between the first timer and the second timer is greater than or equal to the preset duration, it can be ensured that the first node can enable the RF transmission function before permanently disabling or permanently deactivating the RF transmission function. In addition, after the first node performs temporary disabling or temporary deactivation, it takes a cooling period before it can successfully perform permanent disabling or permanent deactivation. Therefore, when the time difference between the first timer and the second timer is greater than or equal to the preset duration, it can be ensured that the first node has the ability to permanently disable or permanently deactivate the RF transmission function after the cooler.

[0138] In a possible implementation, the implementation process of S403 may be: when the first value of the first node satisfies the first verification condition, the environmental Internet of Things device (i.e., the first node) sends the first indication information to the access network device, thereby permanently disabling the device's radio frequency transmission function. Accordingly, the access network device receives the first indication information. The access network device sends the first indication information to the environmental Internet of Things management function network element (i.e., the second node). Accordingly, the environmental Internet of Things management function network element (i.e., the second node) receives the first indication information.

[0139] Furthermore, in some possible implementations, the access network device may send the first indication information to the environment Internet of Things management function network element by transparent transmission. Alternatively, the access network device may also send the first indication information to the environment Internet of Things management function network element by relay transmission. Alternatively, the access network device may also send the first indication information to the environment Internet of Things management function network element by encrypted transmission.

[0140] Of course, the above is only an exemplary description of transmitting the first indication information. The implementation process of transmitting the first message may also be implemented through other transmission methods in the future, and the embodiments of the present application do not impose any restrictions on this.

[0141] In another possible implementation method, the implementation process of S403 can also be: there is a communication link that can directly communicate between the environmental Internet of Things management function network element (i.e., the second node) and the environmental Internet of Things device (i.e., the first node), and there is no need to transfer information through the access network device. The environmental Internet of Things device can send a first indication information to the environmental Internet of Things management function network element through the direct communication link when the first numerical value meets the first verification condition, and then execute permanent disabling or permanent deactivation of the device transmission function.

[0142] It is understandable that, compared to the current environment, the result of the IoT device executing the disable command is not fed back to the core network. In the above technical solution, the first node can send the first indication information. Correspondingly, the second node (i.e., the core network element) receives the first indication information so that the second node can promptly determine whether the first node has permanently disabled or permanently inactivated the radio frequency transmission function.

[0143] Based on the above technical solution, the device disabling method provided by the present application, the second node sends a first message. Correspondingly, the first node receives the first message. Furthermore, the first node performs XOR decryption on the first disabling command based on the random number to determine the first numerical value, and sends a first indication information for instructing the first node to permanently disable or permanently inactivate the radio frequency transmission function when the first numerical value meets the first verification condition. Correspondingly, the second node receives the first indication information to determine the result of the first node executing the disabling command. Since the first message in the above technical solution includes the first disabling command, and the first disabling command is a disabling command determined by XOR-encrypting the first numerical value of the second disabling command at the first preset position with the random number. Therefore, the above technical solution can solve the problem of poor transmission security of the disabling command currently sent by the AIoTMF network element, and greatly improves the security of the disabling command during transmission.

[0144] As a possible embodiment of the present application, Figure 4 ,like Figure 6 As shown, before the above S401, the process of temporarily disabling or temporarily deactivating the radio frequency transmission function of the first node can be implemented through the following S601-S603.

[0145] S601: A second node sends a second message. Correspondingly, a first node receives the second message.

[0146] The second message includes a third disabling command. The second message also includes a second timer. The third disabling command is a disabling command determined by performing XOR encryption on a second value of the second disabling command at a second preset position and a random number. The second timer is used to reflect the time when the second node issues the third disabling command.

[0147] Optionally, the second numerical value refers to the introduction of the second numerical value in S403, which will not be repeated here.

[0148] In a possible implementation, the implementation process of S601 may be: the environment Internet of Things management function network element (i.e., the second node) sends a second message to the access network device. Accordingly, the access network device receives the second message. The access network device sends the second message to the environment Internet of Things device (i.e., the first node). Accordingly, the environment Internet of Things device receives the second message.

[0149] Further, in some possible implementations, the way in which the access network device sends the second information may refer to the way in which the access network device transmits the first information in S401, and will not be described in detail here.

[0150] It can be understood that the second message is also information determined after XOR encryption. Therefore, the access network device can still ensure the security of data transmission by sending the second message to the environmental Internet of Things device through transparent transmission, wireless transparent transmission or relay transmission.

[0151] In another possible implementation method, the implementation process of S601 can also be: there is a communication link that can directly communicate between the environmental Internet of Things management function network element (i.e., the second node) and the environmental Internet of Things device (i.e., the first node), and the environmental Internet of Things management function network element can send a second message to the environmental Internet of Things device through the direct communication link without the need for information transfer through the access network device.

[0152] S602: The first node performs XOR decryption on the third disable command based on the random number to determine a second value.

[0153] In one possible implementation, the third disable command is XOR-decrypted based on a random number to determine the second value. The process of XOR-decrypting the first disable command based on a random number to determine the first value in S402 is referred to, and will not be repeated here.

[0154] S603: When the second value satisfies the second verification condition, the first node sends second indication information. Correspondingly, the second node receives the second indication information.

[0155] The second indication information is used to instruct the first node to temporarily disable or temporarily inactivate the radio frequency transmission function.

[0156] Optionally, the second verification condition includes: the second numerical value is the same as a third numerical value of a preset disabling command at a third preset position.

[0157] It can be understood that by verifying whether the second numerical value is the same as the preset disable command, it can be determined whether the attribute of the third disable command received by the first node is a disable command, and it can also be verified whether the third disable command is issued to the first node, thereby avoiding the situation where the first node incorrectly responds to the disable command. Compared with the current environment where IoT devices cannot verify whether the command comes from a trusted party after receiving the disable command, the above technical solution verifies the first disable command through the first verification condition, which greatly improves the security and reliability of disabling the first node.

[0158] In a possible implementation, the first node sends the second indication information when the second value satisfies the second verification condition. Correspondingly, the second node receives the second indication information. Furthermore, the first node temporarily disables or temporarily deactivates the radio frequency transmission function.

[0159] The process of the first node sending the second indication information can be understood by referring to the process of the first node sending the first indication information in the above S403, and will not be described in detail here.

[0160] Based on the above technical solution, the second node sends a second message. Correspondingly, the first node receives the second message. Furthermore, the first node XORs the third disabling command based on the random number, determines the second numerical value, and sends the second indication information when the second numerical value meets the second verification condition. Correspondingly, the second node receives the second indication information. Since the second message includes the third disabling command, and the third disabling command is a disabling command determined by XOR-encrypting the second numerical value of the second disabling command at the second preset position with the random number. Therefore, the above technical solution can also solve the problem that the disabling command currently sent by the AIoTMF network element has poor transmission security, and greatly improves the security of the third disabling command during transmission.

[0161] As a possible embodiment of the present application, Figure 6 ,like Figure 7 As shown, the process of the second node requesting a random number can be implemented through the following S701-S702.

[0162] S701: A second node sends a first request message. Correspondingly, a first node receives the first request message.

[0163] The first request information is used to request a random number.

[0164] In a possible implementation, the process of the second node sending the first request information refers to the process of the second node sending the first message in S401, which will not be repeated here.

[0165] S702: The first node sends a random number, and the second node receives the random number accordingly.

[0166] In a possible implementation, the process of the first node sending the random number refers to the process of the first node sending the first indication information in S403, which will not be repeated here.

[0167] Optionally, the random number sent by the first node may be a 16-bit random number consisting of binary numbers. For the description of the random number, please refer to the description of the random number in S401, which will not be repeated here.

[0168] Based on the above technical solution, the second node sends the first request information. Accordingly, the first node receives the first request information. The first node sends a random number. Accordingly, the second node receives the random number, so that the second node encrypts the disable command based on the random number, and the first node decrypts the disable command based on the random number.

[0169] As a possible embodiment of the present application, Figure 6 ,like Figure 8 As shown, the process of the second node requesting the second disabling command can be implemented through the following S801-S802.

[0170] S801: A second node sends a second request message. Correspondingly, a third node receives the second request message.

[0171] The second request information is used to request a second disabling command.

[0172] Optionally, while the second node (i.e., the environment Internet of Things management function network element) sends the second request information to the third node (i.e., the unified data management function network element), or before the second node sends the second request information to the third node, or after the second node sends the second request information to the third node, the second node may also send the device identification (e.g., ID) of the first node (i.e., the environment Internet of Things device) to the third node. The third node determines the second disabling command corresponding to the first node from the second disabling commands corresponding to different device nodes according to the device identification of the first node.

[0173] It should be noted that the third node is pre-configured with the second disabling command for the first node. Therefore, the second node can request the second disabling command for the first node from the third node through the device identifier of the first node.

[0174] Furthermore, the first node is also pre-configured with a second disabling command (ie, a preset disabling command) for verifying the disabling command sent by the second node.

[0175] S802: The third node sends a second disabling command. Correspondingly, the second node receives the second disabling command.

[0176] Based on the above technical solution, the second node sends the second request information. Accordingly, the third node receives the second request information. The third node sends the second disabling command. Accordingly, the second node receives the second disabling command, so that the second node can subsequently determine the first disabling command and the third disabling command based on the second proceeding command.
