[0161] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0162] Figure 1 This is a schematic diagram illustrating an application scenario of an access method provided in an embodiment of this application. For example... Figure 1 As shown, this scenario includes a zero-power device 100, a network device 200, and an authentication network element 300. The zero-power device 100 and the network device 200 transmit data via a network, and the network device 200 and the authentication network element 300 transmit data via a network.

[0163] The development of IoT technology has brought about many new application scenarios, including warehouse asset management and inventory management. The 3GPP R19 standard introduced new zero-power devices that can harvest energy from the environment using technologies such as energy harvesting and backscattering, enabling low-cost, low-power passive IoT communication. In this passive IoT communication architecture, network devices need to identify and read / write to zero-power terminal devices to achieve functions such as inventory management. Due to the large number of zero-power devices, supporting group access for different types of zero-power devices is crucial for more efficient inventory management or control operations on specific types of zero-power terminals. Simultaneously, to ensure secure communication between zero-power terminals and the network, two-way authentication is required upon access to prevent fake base stations from illegally obtaining zero-power terminal information and to prevent untrusted terminals from accessing the network. However, traditional access authentication schemes are complex, have high signaling overhead, and require high terminal capabilities, making them unsuitable for zero-power devices. Therefore, a new reliable access scheme needs to be designed for zero-power devices.

[0164] It should be noted that the beneficial effects or technical problems solved by the embodiments of this application are not limited to this one, but may also be other implicit or related problems. For details, please refer to the description of the embodiments below.

[0165] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0166] In one embodiment, such as Figure 2 As shown, an access method is provided, which can be applied to Figure 1 Taking a zero-power device as an example, the explanation includes the following steps:

[0167] S201, send an identity identifier to the network device to instruct the network device to perform an access operation with the zero-power device; or, receive first trigger information sent by the network device and perform an access operation according to the first trigger information; the first trigger information includes first packet information.

[0168] Among them, network equipment can be card reading devices, such as base stations or relay equipment.

[0169] In this embodiment, in scenarios where a network device is inventorying zero-power devices or pageing a specific type of zero-power device to perform corresponding operations—that is, in a contention-based access scenario—after completing initial random access, the zero-power device sends an identity identifier to the network device. Upon receiving the identity identifier, the network device verifies the zero-power device based on the identifier and performs an access operation based on the verification result. For example, if the verification of the zero-power device is successful, the network device interacts with the zero-power device to complete the access operation; if the verification fails, the network device sends an access failure message to the zero-power device.

[0170] Optionally, the identity identifier is a unique identifier for the zero-power device storage, or a device identifier assigned by the network device to the zero-power device storage.

[0171] In this embodiment of the application, in a scenario where a paging access is initiated using a specified type of zero-power device, i.e., in a paging access scenario, the zero-power device receives first trigger information sent by a network device and performs an access operation based on the first packet information and other information in the first trigger information. The zero-power device can verify the network device based on the first packet information, and then perform the access operation based on the verification result, for example, if the verification is successful. Optionally, the first packet information includes at least one of device type, device status, and device location.

[0172] Optionally, the first trigger information may also include command information, which instructs the zero-power device to perform at least one of the following operations: read, write, activate, and deactivate.

[0173] Optionally, the first triggering information may further include scheduling information and / or an access indication; the scheduling information is used to instruct the zero-power device to perform an access operation according to the resources corresponding to the scheduling information; the scheduling information includes at least one of the following: the end time of network device information transmission, time resources specified for transmission by the zero-power device, and frequency resources specified for transmission by the zero-power device; the access indication is used to instruct the zero-power device to perform a contention-based access operation or a non-contention-based access operation. When the first triggering information only includes an access indication, the zero-power device performs an access operation according to the access indication and preset information; when the first triggering information includes both an access indication and scheduling information, the zero-power device determines the corresponding resources according to the scheduling information, and then performs an access operation according to the determined resources and the access indication.

[0174] In the above access method, an identity identifier is sent to the network device to instruct the network device to perform an access operation with the zero-power device; or, a first trigger information sent by the network device is received, and an access operation is performed according to the first trigger information, wherein the first trigger information includes first packet information. Access operations in different scenarios are achieved through simple interaction. In a contention-based access scenario, the network device performs an access operation based on the identity identifier sent by the zero-power device. In a paging access scenario, the network device sends the first packet information along with the first trigger information to the zero-power device, enabling the zero-power device to perform an access operation based on the first trigger information. This eliminates the need for complex data processing by the zero-power device, thus solving the problem that existing technologies are not suitable for access operations between zero-power devices and network devices. Furthermore, performing the access operation based on the first trigger information carrying the first packet information improves the accuracy of the access operation.

[0175] In one embodiment, such as Figure 3 As shown, the above access method may further include:

[0176] S202, Receive first response information sent by network device; the first response information includes first packet information.

[0177] The first group of information includes at least one of the following: device type, device status, and device location.

[0178] In this embodiment of the application, after the zero-power device sends an identity identifier to the network device, if the identity identifier matches the identity identifier pre-stored by the network device, that is, the identity identifier is the same as or has a corresponding relationship with the identity identifier pre-stored by the network device, the network device sends a first response information carrying the first packet information to the zero-power device.

[0179] Optionally, the first response information may also include command information, which instructs the zero-power device to perform at least one of the following operations: read, write, activate, or deactivate. This allows the zero-power device to execute the corresponding operation based on the command information.

[0180] S203: Verify the network device based on the first response information, and perform the access operation if the verification is successful.

[0181] In this embodiment of the application, the zero-power device verifies the network device based on the first packet information in the first response information. If the first packet information is the same as the packet information pre-stored locally by the zero-power device, the verification of the network device is determined to be successful. If the first packet information is different from the packet information pre-stored locally by the zero-power device, the verification of the network device is determined to be unsuccessful.

[0182] As an optional implementation, if the first response information also includes command information, then the corresponding operation is performed according to the command information.

[0183] S204, send a second response message to the network device.

[0184] In this embodiment of the application, a second response information is generated based on the verification result of the network device, and the second response information is sent to the network device. Optionally, if the first response information also includes command information, the second response information is generated based on the verification result of the network device and the operation performed, and the second response information is sent to the network device.

[0199] In this embodiment, after the zero-power device sends its identity identifier to the network device, the network device sends the identity identifier to the authentication network element. The authentication network element verifies the zero-power device. If the identity identifier matches the identity identifier pre-stored by the authentication network element, that is, the identity identifier is the same as or has a corresponding relationship with the identity identifier pre-stored by the authentication network element, the authentication network element sends the first packet information to the network device, so that the network device sends the fourth response information carrying the first packet information to the zero-power device.

[0202] In this embodiment of the application, the zero-power device verifies the network device based on the first packet information in the fourth response information. If the first packet information is the same as the packet information pre-stored locally by the zero-power device, the verification of the network device is determined to be successful.

[0214] The sixth response information can be used to characterize whether the zero-power device has completed the update of the grouping information.

[0215] In this embodiment, the zero-power device returns a sixth response information to the network device based on the update result. The network device forwards the sixth response information to the authentication network element, so that the authentication network element updates the locally stored packet information based on the third packet information. Exemplarily, the interaction process between the zero-power device, the network device, and the authentication network element can be as follows: Figure 8 As shown.

[0216] In this embodiment, the packet information is updated according to the second write command sent by the network device, and the sixth response information is returned to the network device, thereby completing the update of the packet information through a method suitable for zero-power devices.

[0218] In this embodiment, the zero-power device parses the first trigger information to obtain first packet information, and verifies the network device based on the first packet information and locally pre-stored packet information. If the first packet information matches the locally pre-stored packet information, the verification of the network device is deemed successful; if the first packet information does not match the locally pre-stored packet information, the verification of the network device is deemed unsuccessful. Further, if the verification of the network device is successful, a seventh response information is generated based on an identity identifier, and the seventh response information is sent to the network device so that the network device verifies the zero-power device based on the identity identifier. Exemplarily, the interaction process between the zero-power device and the network device can be as follows: Figure 9 As shown.

[0221] In this embodiment, the zero-power device parses the first trigger information to obtain first packet information, and verifies the network device based on the first packet information and locally pre-stored packet information. If the first packet information matches the locally pre-stored packet information, the verification of the network device is deemed successful; if the first packet information does not match the locally pre-stored packet information, the verification of the network device is deemed unsuccessful. Further, if the verification of the network device is successful, an eighth response information is generated based on the identity identifier and sent to the network device. The network device forwards the eighth response information to the authentication network element, so that the authentication network element verifies the zero-power device based on the identity identifier. Exemplarily, the interaction process between the zero-power device, the network device, and the authentication network element can be as follows: Figure 10 As shown.

[0222] In this embodiment, the zero-power device sends the eighth response information carrying the identity identifier to the network device, so that the network device can verify the zero-power device according to the eighth response information, thereby completing the two-way authentication between the zero-power device and the network device. Furthermore, the verification of the zero-power device in the authentication network element saves the computing resources and storage space of the network device.

[0223] In one embodiment, such as Figure 11 As shown, the above access method may further include:

[0224] S214, before sending the identity identifier to the network device, receive the second trigger information sent by the network device.

[0225] In this embodiment of the application, before the zero-power device sends its identity identifier to the network device, the zero-power device and the network device perform an initial random access, and the network device sends a second triggering information to the zero-power device.

[0226] S215, in response to the second triggering information, sends a temporary identity identifier to the network device.

[0227] In this embodiment, the zero-power device responds to the second trigger information, accesses the network based on the time-slot-ALOHA algorithm, randomly generates a temporary identity identifier, and sends the temporary identity identifier to the network device so that the network device can perform initial random access based on the temporary identity identifier.

[0228] S216, Receive the ninth response information returned by the network device.

[0229] In this embodiment of the application, the ninth response information can characterize whether the initial random access was successful. If the initial random access was successful, the zero-power device and the network device continued to perform the access operation. If the initial random access failed, the zero-power device failed to access the network device.

[0230] In this embodiment, before sending the identity identifier to the network device, the zero-power device performs an initial random access with the network device, making the access process complete.

[0231] In one embodiment, such as Figure 12 As shown, an access method is provided, which can be applied to Figure 1 Taking network devices as an example, the explanation includes the following steps:

[0232] S301, receive the identity identifier sent by the zero-power device, and perform an access operation with the zero-power device based on the identity identifier; or, send first trigger information to the zero-power device to instruct the zero-power device to perform an access operation with the network; the first trigger information includes first packet information.

[0233] Among them, network equipment can be card reading devices, such as base stations or relay equipment.

[0234] In the embodiments of this application, in scenarios where the network device is inventorying zero-power devices or paging a specific type of zero-power device to perform corresponding operations, that is, in a contention access scenario, after completing the initial random access, the zero-power device sends an identity identifier to the network device. After receiving the identity identifier, the network device performs an access operation with the zero-power device based on the identity identifier.

[0235] In this embodiment of the application, in a scenario where a paging access is initiated using a specified type of zero-power device, i.e., in a paging access scenario, the zero-power device receives first trigger information sent by a network device and performs an access operation based on the first packet information and other information in the first trigger information. The zero-power device can verify the network device based on the first packet information, and then perform the access operation based on the verification result, for example, if the verification is successful. Optionally, the first packet information includes at least one of device type, device status, and device location.

[0236] Optionally, the first trigger information may also include command information, which instructs the zero-power device to perform at least one of the following operations: read, write, activate, and deactivate.

[0237] Optionally, the first triggering information may further include scheduling information and / or an access indication; the scheduling information is used to instruct the zero-power device to perform an access operation according to the resources corresponding to the scheduling information; the scheduling information includes at least one of the following: the end time of network device information transmission, time resources specified for transmission by the zero-power device, and frequency resources specified for transmission by the zero-power device; the access indication is used to instruct the zero-power device to perform a contention-based access operation or a non-contention-based access operation. When the first triggering information only includes an access indication, the zero-power device performs an access operation according to the access indication and preset information; when the first triggering information includes both an access indication and scheduling information, the zero-power device determines the corresponding resources according to the scheduling information, and then performs an access operation according to the determined resources and the access indication.

[0238] In the above access method, an identity identifier sent by a zero-power device is received, and an access operation is performed with the zero-power device based on the identity identifier; or, a first trigger information is sent to the zero-power device to instruct the zero-power device to perform an access operation with the network, wherein the first trigger information includes first packet information. Access operations in different scenarios are achieved through simple interaction. In a contention-based access scenario, the network device performs an access operation based on the identity identifier sent by the zero-power device. In a paging access scenario, the network device sends the first packet information along with the first trigger information to the zero-power device, enabling the zero-power device to perform an access operation based on the first trigger information. This eliminates the need for complex data processing by the zero-power device, thus solving the problem that existing technologies are not suitable for access operations between zero-power devices and network devices. Furthermore, performing the access operation based on the first trigger information carrying the first packet information improves the accuracy of the access operation.

[0239] In one embodiment, one implementation of S301 above is provided, such as... Figure 13 As shown, the aforementioned "access operation based on identity and zero-power device" may include:

[0240] S401 verifies zero-power devices based on their identity identifier.

[0241] In this embodiment of the application, in a scenario of contention for access, the network device verifies the zero-power device based on the identity identifier. For example, if the identity identifier is the same as the locally stored identity identifier, the verification of the zero-power device is determined to be successful; if the identity identifier is different from the locally stored identity identifier, the verification of the zero-power device is determined to be unsuccessful.

[0242] S402, upon successful verification, enables access to zero-power devices.

[0243] In this embodiment, the access operation is performed based on the verification result of the zero-power device. For example, if the verification of the zero-power device is successful, the network device interacts with the zero-power device to complete the access operation; if the verification of the zero-power device fails, the network device sends an access failure message to the zero-power device.

[0244] In this embodiment, the zero-power device is verified based on its identity identifier, and access is performed only if the verification is successful, thereby improving the security of the zero-power device accessing the network device.

If the verification is successful, the access operation is performed with the zero-power device, which improves the security of the access operation. The zero-power device is verified in the authentication network element, which saves the computing resources and storage space of the network device.

If the initial random access failed, the zero-power device failed to access the network device.

[0309] In this embodiment, before sending the identity identifier to the network device, the zero-power device performs an initial random access with the network device, making the access process complete.

[0310] In one embodiment, such as Figure 22 As shown, an access method is provided, which can be applied to Figure 1 Taking the authentication network element in the example, the following steps are included:

[0311] S801, receive the identity identifier sent by the network device, verify the zero-power device according to the identity identifier, and send the verification result to the network device to instruct the network device to perform an access operation with the zero-power device if the verification result indicates that the verification is successful; or, send the first packet information to the network device to instruct the network device to generate the first trigger information according to the first packet information.

[0312] In this embodiment, after the zero-power device sends its identity identifier to the network device, the network device sends the identity identifier to the authentication network element. The authentication network element verifies the zero-power device. If the identity identifier matches an identity identifier pre-stored by the authentication network element (i.e., the identity identifier is the same as or corresponds to an identity identifier pre-stored by the authentication network element), the authentication network element sends a first packet of information to the network device, causing the network device to send a fourth response message carrying the first packet of information to the zero-power device. The zero-power device verifies the network device based on the first packet of information in the fourth response message. If the first packet of information matches the packet of information pre-stored locally by the zero-power device, the verification of the network device is deemed successful. If the first packet of information differs from the packet of information pre-stored locally by the zero-power device, the verification of the network device is deemed unsuccessful. Further, the zero-power device performs an access operation based on the verification result of the network device.

[0313] Optionally, the fourth response information may also include command information, which instructs the zero-power device to perform at least one of the following operations: read, write, activate, or deactivate. This allows the zero-power device to execute the corresponding operation based on the command information.

[0314] In the above access method, an identity identifier sent by the network device is received, the zero-power device is verified based on the identity identifier, and a verification result is sent to the network device to instruct the network device to perform an access operation with the zero-power device if the verification result indicates that the verification is successful; or, a first packet of information is sent to the network device to instruct the network device to generate first trigger information based on the first packet of information. Access operations in different scenarios are achieved through simple interaction, eliminating the need for complex data processing by the zero-power device. This solves the problem that existing technologies are not suitable for access operations between zero-power devices and network devices. Furthermore, verification and storage are performed within the authentication network element, saving storage space and computing resources for the network device.

[0315] In one embodiment, such as Figure 23 As shown, the above access method also includes:

[0316] S802 receives the fifth response information sent by the network device.

[0317] In this embodiment of the application, a fifth response information is generated based on the verification result of the network device, and the fifth response information is sent to the network device. The network device forwards the fifth response information to the authentication network element. Optionally, if the fourth response information also includes command information, the fifth response information is generated based on the verification result of the network device and the operation performed, and the fifth response information is sent to the network device.

[0318] In this embodiment, in response to the fourth response information sent by the network device, the network device is verified, thereby completing the two-way authentication between the network device and the zero-power device, ensuring the access security between the network device and the zero-power device, and performing the access operation when the verification is successful. The zero-power device is verified in the authentication network element, saving the computing resources and storage space of the network device.

[0319] In one embodiment, such as Figure 24 As shown, the above access method also includes:

[0320] S803 sends the updated third packet information to the network device to instruct the network device to send the third packet information to the zero-power device in the second write command.

[0321] In this embodiment, after the network device receives the fifth response message, it forwards the fifth response message to the authentication network element. The authentication network element can trigger packet information updates according to preset requirements, obtain the updated third packet information, and send the updated third packet information to the network device. The network device generates a second write command based on the updated third packet information and further sends the second write command to the zero-power device. The zero-power device updates the locally stored first packet information to the updated third packet information according to the second write command.

[0322] Optionally, the preset requirements include any one of the following: updates triggered by device type changes, updates triggered by device status changes, security-based periodic updates, and security-based irregular updates.

[0323] S804 receives the sixth response information sent by the network device.

[0324] The sixth response information can be used to characterize whether the zero-power device has completed the update of the grouping information.

[0325] In this embodiment, the zero-power device returns a sixth response information to the network device based on the update result. The network device forwards the sixth response information to the authentication network element, so that the authentication network element updates the locally stored packet information based on the third packet information. Exemplarily, the interaction process between the zero-power device, the network device, and the authentication network element can be as follows: Figure 8 As shown.

[0326] In this embodiment, the packet information is updated according to the second write command sent by the network device, and the sixth response information is returned to the network device, thereby completing the update of the packet information through a method suitable for zero-power devices.

[0327] In one embodiment, such as Figure 25 As shown, the above access method also includes:

[0328] S805 receives the eighth response information sent by the network device; the eighth response information includes an identity identifier.

[0329] In this embodiment, the zero-power device parses the first trigger information to obtain first packet information, and verifies the network device based on the first packet information and locally pre-stored packet information. If the first packet information matches the locally pre-stored packet information, the verification of the network device is deemed successful; if the first packet information does not match the locally pre-stored packet information, the verification of the network device is deemed unsuccessful. Further, if the verification of the network device is successful, an eighth response information is generated based on the identity identifier and sent to the network device, which then forwards the eighth response information to the authentication network element.

[0330] S806 verifies the zero-power device based on the eighth response information.

[0331] In this embodiment, the authentication network element parses the eighth response information to obtain an identity identifier. It then determines the verification result for the zero-power device by comparing the identity identifier with the identity identifier pre-stored locally within the authentication network element. If they match, the verification passes; otherwise, the verification fails.

[0332] S807 sends the verification result to the network device.

[0333] In this embodiment of the application, the network device receives the verification result returned by the authentication network element, thereby completing the access operation.

[0334] In this embodiment, the zero-power device sends the eighth response information carrying the identity identifier to the network device so that the authentication verifies the zero-power device based on the eighth response information, thereby completing the two-way authentication between the zero-power device and the network device. Furthermore, the verification of the zero-power device in the authentication network element saves the computing resources and storage space of the network device.
