Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to an access method, device, system, storage medium, and program product. Background Technology

[0002] In recent years, with the widespread application of IoT technology in the field of wireless communication, reducing the size, complexity, and power consumption of IoT devices has become a major focus. Since most wireless communication devices require manual battery replacement or are powered by rechargeable batteries, this leads to high maintenance costs and even safety hazards. With the continuous introduction of digital age demands and the improvement of automation levels, there is an urgent need to introduce new IoT technologies to support devices without energy storage capabilities or those requiring no manual replacement or recharging. To this end, A-IoT (Ambient Internet of Things) technology, supporting higher-density connectivity, lower complexity, and lower power consumption, has been proposed. A-IoT describes a vast IoT ecosystem where every object is connected to a wireless sensor network through low-cost, self-powered sensor nodes. A-IoT devices use sensors, data analytics, and connectivity to adapt to their environment. These devices are often inconspicuous, embedded in our daily lives, capable of collecting and processing data from their surroundings and autonomously responding to changing conditions, making them highly adaptable to a variety of important application scenarios.

[0003] The access of IoT devices provides the necessary prerequisites for subsequent uplink and downlink data transmission, such as reading and writing, and is a crucial link in IoT communication scenarios.

[0061] In the above embodiments, by designing the signaling flow between the first device and the second device, effective access for one or more IoT devices that have been identified by the network can be effectively achieved. The following will describe the solution of this disclosure using specific embodiments as examples.

[0062] Figure 1 This is a flowchart illustrating some embodiments of the access method disclosed herein. The embodiment includes steps S110-S120.

[0063] In step 110, the first device receives a first signaling sent by the second device, wherein the first signaling is used to instruct the first device to perform an access procedure.

[0064] The first signaling includes at least one of the following: information about the first device, first control information, second control information, transmission channel information on the link from the second device to the first device, user re-identification information, and first user authentication information. The first control information is used for transmission from the second device to the first device, and the second control information is used for transmission from the first device to the second device. For example, the first control information is control information for R2D (Reader to Device) transmission, the second control information is control information for D2R (Device to Reader) transmission, and the transmission channel information on the link from the second device to the first device is, for example, PRDCH (Physical Reader to Device Channel, transmission channel on the R2D link) information.

[0065] In some embodiments, the information of the first device may be at least one of the following: identification information of the first device, device type request information, device type confirmation information, device capability request information, and device capability confirmation information. The identification information of the first device is used to identify the first device, the device type request information is used to identify the type of device to be accessed, the device type confirmation information is used to identify the type of device already identified by the second device, the device capability request information is used to identify the capability of the device to be accessed, and the device capability confirmation information is used to identify the capability of the device already identified by the second device.

[0066] The identification information of the first device includes at least one of an ID (Identity document) and a temporary identifier. The temporary identifier includes a random number identifier and an RNTI (Radio Network Temporary Identifier), for example, RN16.

[0067] In some embodiments, the first control information includes at least one of command information, first scheduling information, and first verification information.

[0068] The command information includes at least one of the following: inventory command, access command, selection command, wake-up command, and call command. The inventory command is used to identify the first device. The access command is used to determine whether the first device is communicating with the second device. The selection command allows the second device to select the first device based on predefined criteria. The wake-up command is similar to a paging command, informing the first device that a message has arrived. The call command is used by the core network to send an authentication notification to a specific first device.

[0069] The first scheduling information includes at least one of the following: command format information, first rate information, first carrier frequency information, first frequency location information, first bandwidth size information, first time-domain granularity number information, first time-domain granularity duration information, first time-domain location information, first transport block information, first modulation information, first code rate information, first encoding information, first repetitive transmission information, first frequency hopping indication information, and first synchronization format information. This first scheduling information is used to instruct the first device to use the scheduling resource to send a message, or to instruct the second device to use the scheduling resource to send a message next time.

[0070] The first verification information includes: first cyclic redundancy check (CRC) information, such as the number of bits, format, and generation formula of the CRC check. This first verification information is used to indicate how the first device verifies the received information, or to indicate how the second device will verify the information sent by the first device next time.

[0071] In some embodiments, the second control information includes at least one of: second scheduling information and second verification information.

[0072] The second scheduling information includes at least one of the following: second rate information, second carrier frequency information, second frequency location information, second bandwidth size information, second time-domain granularity number information, second time-domain granularity duration information, second time-domain location information, second transport block information, second modulation information, second code rate information, second encoding information, second repetitive transmission information, second frequency hopping indication information, second synchronization format information, and intermediate synchronization code indication information. This second scheduling information is used to instruct the second device to use the scheduling resource to send a message, or to instruct the first device to use the scheduling resource to send a message next time.

[0073] The second verification information includes second cyclic redundancy check (CRC) information, such as the number of bits, format, and generation formula of the CRC check. This second verification information is used to indicate how the second device verifies the received information, or to indicate how the first device will verify the information sent by the second device next time.

[0074] In some embodiments, the first user authentication information includes at least one of: first authentication information and first encryption information. The first authentication information includes at least one of authentication request information and first authentication confirmation information. The authentication request information indicates that the first device has not yet been authenticated and requires encryption authentication. The first authentication confirmation information indicates that the first device has already been authenticated, and re-authentication is required due to re-access. The first encryption information includes at least one of encryption algorithm information, encryption method information, encryption request information, and first encryption confirmation information. The encryption request information identifies a request to encrypt an unencrypted first device. The first encryption confirmation message indicates that the first device has already been encrypted, and re-confirmation of encryption is required due to re-access.

[0075] In step 120, the first device performs an access procedure based on the first signaling.

[0076] For example, if the identification information of the first device matches the identification information of the first device stored in its own memory, then the access process is executed according to the parameters carried in the first signaling.

[0077] In the above embodiments, by designing the signaling flow between the first device and the second device and the bit information that the signaling must carry, it is possible to enable the second device to trigger the first device to execute the access process.

[0078] Figure 2 This is a flowchart illustrating some other embodiments of the access method disclosed herein. This embodiment includes steps S210-S220.

[0079] In step S210, the first device sends a second signaling message to the second device, which is used to instruct the first device to request an access procedure.

[0080] The second signaling includes at least one of the following: second user authentication information, transmission channel information on the first device to second device link, and information about the first device. The transmission channel information on the first device to second device link is, for example, PDRCH (Physical Device to Reader Channel, transmission channel on a D2R link) information.

[0081] In some embodiments, the second user authentication information includes at least one of: second authentication information and second encryption information. The second authentication information includes at least one of: second authentication confirmation information and authentication content information; the second encryption information includes at least one of: second encryption confirmation information and encrypted content information.

[0082] In some embodiments, the identification information of the first device has been pre-identified by the second device. For example, the reader has pre-identified the IoT device, therefore, the reader has identified or is aware of the identification information of the first device. The identification information of the first device sent by the reader may be the same as or different from the identification information stored by the first device. If the identification information of the first device sent by the reader is the same as the identification information stored by the first device, the first device can perform the access procedure; if the identification information of the first device sent by the reader is different from the identification information stored by the first device, the first device cannot perform the access procedure.

[0083] In some embodiments, the second signaling is transmitted in a backscattering manner or an autonomous transmission manner. For example, the IoT device is capable of collecting and storing electromagnetic wave energy, and using the stored energy to transmit signals; therefore, the IoT device can transmit the second signaling in a backscattering manner.

[0084] In step S220, the first device performs an access procedure based on the second signaling.

[0085] In this embodiment, the access process is initiated by the first device through signaling interaction between the first device and the second device.

[0086] Figure 3 This is a flowchart illustrating another embodiment of the access method disclosed herein, which includes steps S110 and S310.

[0087] In step S110, the first device receives a first signaling sent by the second device, which instructs the first device to perform an access procedure.

[0088] The first signaling carries at least one of the following: IoT device information, R2D transmission control information, D2R transmission control information, PRDCH information, user re-identification information, and user authentication information.

[0089] In step S310, the first device sends a second signaling message to the second device, which is used to instruct the first device to respond to the access procedure.

[0090] The second signaling carries at least one of the following: user authentication information, PDRCH information, and IoT device information.

[0091] In this embodiment, the effective access of one or more IoT devices that have been identified by the network can be effectively achieved through the signaling process between the first device and the second device and the bit information that each signaling must carry.

[0092] Figure 4 This is a flowchart illustrating some other embodiments of the access method disclosed herein, including steps S110, S310, and S410.

[0093] In step S410, the first device receives a third signaling sent by the second device, wherein the third signaling includes at least one of a response message to the second signaling and contention resolution information.

[0094] For example, after receiving the second signaling, the reader sends a response message to the IoT device, indicating that the reader has successfully received the message sent by the IoT device.

[0095] In the above embodiments, effective access for IoT devices was achieved.

[0096] In some embodiments of this disclosure, such as Figure 5 As shown, it may also include only steps S210 and S410. Further elaboration is not provided here.

[0097] In some other embodiments of this disclosure, the first device also initializes the access process using pre-configuration information. For example, this pre-configuration process is performed before steps S110 and S210.

[0098] For example, configure pre-configuration information in the RRC (Radio Resource Control) parameters. This includes configuring at least one of the access method parameters and access resource parameters in the RRC parameters.

[0099] For example, pre-configuration information can be configured at the MAC (Media Access Control) layer. This includes configuring at least one of the access method parameters and access resource parameters in the MAC-CE (Control Element) or MAC layer.

[0100] For example, pre-configuration information is configured in the access layer above the MAC layer, such as the A-IoT (Environmental Internet of Things) layer. This includes configuring at least one of the access method parameters and access resource parameters in the access layer above the MAC layer.

[0101] Alternatively, new configuration or instruction methods can be used to configure the access method or access resources.

[0102] In other embodiments of this disclosure, the second device performs at least one of the following: sending a first signaling to the first device, wherein the first signaling is used by the first device to perform an access procedure; and receiving a second signaling sent by the first device, wherein the second signaling is used by the first device to perform an access procedure.

[0103] The first signaling includes at least one of the following: information of the first device, first control information, second control information, transmission channel information on the link from the second device to the first device, user re-identification information, and first user authentication information. The first control information is used for transmission from the second device to the first device, and the second control information is used for transmission from the first device to the second device.

[0104] The second signaling includes at least one of the following: second user authentication information, transmission channel information on the link between the first device and the second device, and information of the first device.

[0105] The specific parameters of the first and second signaling have been described in detail in the above embodiments and will not be elaborated further here.

[0106] In other embodiments, the second device sends a third signaling message to the first device, wherein the third signaling message includes at least one of a response message to the second signaling message and contention resolution information.

[0107] In some other embodiments of this disclosure, since the first device is a device that has been identified by the network, the first device may also adopt a contention access scheme before the network identifies the first device.

[0108] For example, the first device receives a fourth signaling message sent by the second device, the parameters carried by the fourth signaling message being consistent with the parameters carried by the first signaling message. The first device sends a fifth signaling message to the second device, for example, the first device sends the fifth signaling message to the second device based on a first resource unit corresponding to the second scheduling information, the parameters carried by the fifth signaling message being consistent with the parameters carried by the second signaling message. The first device receives a sixth signaling message sent by the second device, for example, the first device receives the sixth signaling message sent by the second device in response to the number of one or more devices accessing the second device based on the first resource unit being no greater than 1, the parameters carried by the sixth signaling message being consistent with the parameters carried by the first signaling message. The first device sends a seventh signaling message to the second device, for example, the first device sends the seventh signaling message to the second device in response to the sixth signaling message carrying a first device identifier, the seventh signaling message carrying at least one of the first device identifier and the second device identifier of the first device.

[0109] The following section uses an IoT device as an example for the first device and a reader as an example to introduce the publicly available solutions.

[0110] Figure 6 This is a flowchart illustrating some other embodiments of the access method disclosed herein. This embodiment includes steps S610-S630.

[0111] In step 610, the reader sends downlink signaling to the identified IoT device to trigger the IoT device to access the network. This downlink signaling can be labeled Msg.A. Msg.A can carry IoT identifier, control information transmitted via R2D, control information transmitted via D2R, PRDCH information, user re-identification information, user authentication information, etc.

[0112] In step S620, the IoT device determines whether the received IoT identification information matches the configured IoT identification information. If they match, step S630 is executed.

[0113] By comparing IoT identification information, it can be determined whether the reader has triggered access to itself.

[0114] In step S630, the IoT device sends a response message to the reader. This response message can be labeled Msg.B, and Msg.B can carry IoT identifiers, IoT device capability information, IoT device type information, etc.

[0115] In this embodiment, the reader selects one, a group, or all IoT devices within its coverage area to participate in inventory, and simultaneously sends read and write commands to the IoT devices. The IoT devices in this embodiment are those already recognized by the network; therefore, a non-contention-based access method is used.

[0116] In some embodiments, only step S610 may be included, that is, for IoT devices that have been identified by the reader, the reader only needs to send Msg.A, which carries the device's identification information and instruction information to complete an access process.

[0117] In other embodiments of this disclosure, such as Figure 7 As shown, Figure 7 This is a flowchart illustrating some other embodiments of the access method disclosed herein. This embodiment includes steps S610-S630 and step S710.

[0118] In step S710, the reader sends an ACK (Acknowledge character) signal to the IoT device.

[0119] For example, the signaling in Msg.A indicates uplink data transmission. After receiving the Msg.B message, the reader should send back an ACK signal to indicate that the gNB or intermediate node has successfully received it. If Msg.B is not successfully received or parsed by the reader, the reader can re-initiate the trigger message after waiting for a period of time.

[0120] Figure 8 This is a flowchart illustrating some other embodiments of the access method disclosed herein. This embodiment includes steps S810-S840.

[0121] In step S810, the reader sends downlink signaling to the identified IoT device, which carries the device identifier.

[0122] In step S820, the IoT device determines whether the received IoT identification information matches the configured IoT identification information. If they match, step S830 is executed.

[0123] In step S830, the IoT device sends a response message to the reader.

[0124] In step S840, the reader sends uplink / downlink scheduling information or data information to the IoT device.

[0125] In this embodiment, the reader selects one, a group, or all IoT devices within its coverage area to participate in inventory. Msg.A only transmits a trigger signal carrying device identification information. After receiving a response message from Msg.B, the reader sends read, write, or other commands to the IoT device. Since the IoT devices in this embodiment are already recognized by the network, a non-contention-based access method is used.

[0126] Figure 9 This is a flowchart illustrating some other embodiments of the access method disclosed herein. This embodiment includes steps S910-940.

[0127] In step S910, the reader sends an access request instruction to the identified IoT device, which does not contain device identification information.

[0128] In step S920, the IoT device sends a response message to the reader, which carries device identification information. This response message may also carry data information.

[0129] In step S930, the reader parses the device identification information.

[0130] In step S940, the reader sends read / write instructions to the IoT device.

[0131] In the above embodiment, the Msg.A message sent by the reader to the IoT device does not carry device ID information, but is only an access request instruction. After the IoT device receives Msg.A, it returns the device ID information by returning Msg.B. Then, the reader sends subsequent uplink and downlink data or control information as needed, thereby completing the effective access of the device.

[0132] Before the network identifies an IoT device, the reader sends Message.0 to the A-IoT device to trigger the access process. This message may be sent after the reader finds the target A-IoT device set through paging messages, and then initiates an access round by carrying the first parameter information in Message.0. The first parameter information provides the A-IoT device with an optional access opportunity for this round, and the design of this value can effectively control access conflicts.

[0133] After receiving Message.0, the A-IoT device checks whether it meets the corresponding conditions, such as whether the selected access time has arrived. If the conditions are met, the A-IoT device sends Message.1 to the reader. This message contains a randomly generated value used to temporarily identify the device, which can be denoted as RN.

[0134] After receiving the RN from the A-IoT device, the reader sends an ACK message containing the same RN to the A-IoT device, denoted as Message.2, to confirm successful reception. If multiple A-IoT devices send their respective RNs simultaneously at the same time, and the reader cannot correctly parse them, then this round of access fails.

[0135] If the A-IoT device successfully receives an ACK message with the same RN as described above, the A-IoT device sends its device ID and other information to the reader, denoted as Message.3. Otherwise, the A-IoT device transmits nothing and enters a waiting state.

[0136] Additionally, to resolve conflicts, the reader can send Message.4. For A-IoT devices that connect without conflict, the reader sends an ACK message carrying the same RN value, indicating that the A-IoT device has successfully connected and can proceed with subsequent uplink / downlink command or data transmission. If the reader does not receive Message.3 or if a conflict occurs between different device IDs with the same RN, the A-IoT device will receive a NAK message and enter a waiting state.
