[0035] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this. It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0036] The access method, apparatus, device, and storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0037] Figure 2 This is one of the flowcharts illustrating the access method provided in an embodiment of this application. For example... Figure 2 As shown, the access method includes:

[0038] Step 210: The first device listens for or receives the first object;

[0039] Optionally, the first device is at least one of the following:

[0040] Passive, semi-passive, or active environmental AIoT devices;

[0041] AIoT devices are categorized by device type, which includes device 1, device 2a, or device 2b.

[0042] AIoT devices are categorized according to the supported communication types, which include Device Autonomous Initiated DO-A, Device Initiated DO-DTT triggered by device termination, or Device Termination DT.

[0043] Understandably, the first device is an AIoT device.

[0044] Ambient IoT, also known as Ambient Power-Enabled Internet of Things (AIoT), is a type of IoT service. AIoT devices are powered through energy harvesting; they either do not have batteries or have limited energy storage capacity (e.g., using a capacitor). These devices have low overall power consumption, including low-power signal reception and low-power signal transmission. Due to their low overall power consumption, the energy for communication can be derived from the environment, such as wind power, kinetic energy, heat energy, or radio frequency (RF) signals. They can also be called Ambient IoT devices, passive IoT devices, or response devices.

[0045] Ambient IoT devices can be categorized based on their energy source, energy storage capability, and whether they are passive or active transmitters, encompassing various device types:

[0046] Passive devices, such as device 1, have no energy storage and no independent signal generation / amplification capabilities; they communicate via backscattering.

[0047] Semi-passive devices, such as device 2a, also belong to the broad category of passive devices. They have energy storage but do not generate independent signals; they communicate through backscattering. The stored energy can be used to amplify the reflected signal.

[0048] Active devices, such as device 2b, have energy storage and independent signal generation capabilities, meaning they contain active radio frequency components for transmission.

[0049] Devices with different energy storage capacities also affect their transmission quality. Generally, devices with higher energy storage capacity also mean higher receiving sensitivity or higher transmitting power, resulting in better reliability of the receiving or transmitting link.

[0050] The main data / service types of AIoT include:

[0051] DO: Device-originated. DO devices typically send various data, requests, or instructions, meaning they are initiated by the device itself.

[0052] DT: Device-terminated. DT devices typically receive instructions, data, or requests from other devices or systems, meaning they are terminated at the device.

[0053] DO data indicates that the data stream originates from an AIoT device (similar to an RFID tag). DT data indicates that the data stream is transmitted to an AIoT device.

[0054] For data streams originating from AIoT devices, i.e., DO data, they can be further categorized as follows:

[0055] 1) DO-A: Device Autonomous (DO autonomous), meaning that AIoT devices autonomously initiate data transmission.

[0056] For example, connecting a large number of various sensors that collect and proactively report information about the environment, equipment, and organisms when necessary.

[0057] 2) DO-DTT: Device-terminated triggered, meaning that base station or other reader / writer devices trigger AIoT devices to initiate data transmission.

[0058] For example, asset identification, status reporting, and tracking are all DL-triggered reports, where the reader collects data from tags by triggering inventory procedures. Since AIoT devices generate data and initiate data transmission, this service should be considered as a DO service initiated by the AIoT device, triggered by control commands from the reader side.

[0059] According to the above device types, the first device can be a passive, semi-passive, or active environmental IoT (AIoT) device.

[0060] The first device can be an AIoT device categorized by device type, including types 1 / 2a / 2b, etc.

[0061] The first device can be an AIoT device categorized according to the supported communication types. These communication types include: DT, DO-DTT, DO-A, etc.

[0062] Optionally, the second device is a reader. Optionally, the reader can be a terminal, an intermediate node, or a network-side device, that is, the second device can also be a terminal, an intermediate node, or a network-side device.

[0063] Due to issues such as self-interference, network-side devices, terminals, intermediate nodes, or assisting nodes can be multiple. For example, multiple readers can each handle either receiving or sending functions, thus supporting send-receive separation.

[0064] Optionally, the first device is a tag. It should be noted that in Radio Frequency Identification (RFID) technology, a tag is a wireless device used to identify and track items. An RFID tag consists of a chip and an antenna, and can communicate with a reader via radio frequency signals. In this embodiment, a tag can also be used to refer to an AIoT device.

[0065] It should be noted that "reader" usually refers to a reading and writing device, a hardware device used to capture or read and write information from RFID tags, barcodes, QR codes, etc. In this application, "reader" is referred to as a reader / writer, used to refer to a device capable of reading and writing information.

[0066] In this embodiment of the application, reader can also be represented as:

[0067] Scanner: Usually refers to a device that reads and writes barcodes or QR codes;

[0068] Reader / writer: If the device has both reading and writing capabilities.

[0069] RFID reader / writer: This term can be used when specifically referring to reading and writing devices used for RFID technology.

[0070] Sensor: In some cases, especially in RFID technology, a "reader" can also be called a sensor because it senses the tag via wireless signals.

[0071] Optionally, the first object includes at least one of the following:

[0072] carrier wave;

[0073] Timing information or signals, which are used to indicate time information or synchronization information.

[0074] The first configuration information is used to instruct the first device to configure the access process.

[0075] It is understood that the first device receiving or listening to the first object can obtain at least one of the following: a carrier wave, the timing of the first device initiating an access procedure, and the configuration for executing the access procedure.

[0076] Step 220: The first device sends a first message to the second device, the first message being used to initiate the access process;

[0077] The first device receives or listens to the first object, and can obtain the carrier, the timing of the first device initiating the access procedure, and / or the configuration for executing the access procedure, thereby initiating an access procedure based on the carrier, the timing of the first device initiating the access procedure, and / or the configuration for executing the access procedure.

[0078] Optionally, the first message is a Device to Reader (D2R) message.

[0079] Optionally, the first message includes at least one of the following:

[0080] The first message in the four-step random access process, such as Msg1;

[0081] The first message in a two-step random access procedure, such as MsgA;

[0082] The first message of a competition-based random access procedure;

[0083] The first message of a contention-free random access procedure.

[0084] Optionally, the four-step random access procedure can be a contention-based four-step random access procedure or a contention-free four-step random access procedure.

[0085] Optionally, the two-step random access procedure can be a contention-based two-step random access procedure or a contention-free two-step random access procedure.

[0086] Optionally, the contention-based random access procedure can be a contention-based four-step random access procedure or a contention-based two-step random access procedure.

[0087] Optionally, a contention-free random access procedure can be a contention-free four-step random access procedure or a contention-free two-step random access procedure.

[0088] In some embodiments, the first message is transmitted based on the backscattering of the carrier, wherein the first device is a passive or semi-passive AIoT device.

[0089] It is understandable that passive or semi-passive devices can initiate the access process based on carrier backscattering. That is, AIoT devices do not send D2R messages after receiving Reader to Device (R2D) request messages, but actively send D2R messages by backscattering the carrier to initiate the access process or transmit data.

[0090] Optionally, the carrier wave is transmitted continuously, periodically, or event-triggered.

[0091] In some embodiments, the carrier wave is transmitted by a second device (such as a Reader). The Reader can transmit the carrier wave as needed for the service. Continuously transmitted carrier waves help provide more access opportunities, thereby reducing the latency for AIoT devices to initiate access. Periodically transmitting carrier waves by the Reader can support AIoT devices to periodically execute AIoT services; the Reader can also transmit carrier waves based on occasional service needs (i.e., event-triggered). Periodic or event-triggered carrier waves help the Reader save energy when transmitting carrier waves.

[0092] Optionally, the first device initiates the access process, which can be a proactive access process. An AIoT device can proactively initiate an access process (DO-A) after detecting a carrier wave.

[0093] Optionally, the access process initiated by the first device can also be passively initiated.

[0094] The access method provided in this application embodiment involves a first device listening to or receiving a first object and sending a first message to a second device to initiate an access process. This enables the first device to initiate an access process based on a carrier wave, timing information, or signal and / or first configuration information, expanding the application scenarios of passive or semi-passive AIoT devices and making it possible for low-cost, low-power AIoT devices to support active access.

[0095] Optionally, before initiating the access process, the AIoT device receives timing information or listens for timing signals. Based on the timing information or timing signals and the first configuration information, the AIoT device determines when to initiate the access process.

[0096] Optionally, the timing information includes at least one of the following:

[0097] 1) Time information, such as hours, minutes, and seconds. It can be understood that the AIoT device initiates the access process at a specific point in time. The AIoT device determines this specific point in time based on this time information. Benefit: AIoT devices are low-cost devices and may not have a clock system, thus they cannot determine the time independently and need to determine the time based on timing information sent by the Reader.

[0098] 2) Frame number or timeslot number: The AIoT device determines the current time based on the frame number or timeslot number, thereby determining the timing for initiating the access process, or determining whether the timing for initiating the access process has arrived.

[0099] Optionally, the timing information is carried via paging messages or query messages.

[0100] Optionally, the timing information is indicated in one of the following ways:

[0101] Synchronization signal;

[0102] Beacon signal;

[0103] Trigger signal;

[0104] Reader-to-Device (R2D) signal;

[0105] Preamble.

[0106] For example, AIoT devices continuously listen for and count synchronization signals to determine when it is time to initiate an access process. Optionally, the synchronization signal is sent periodically.

[0107] Optionally, the timing signal includes one of the following:

[0108] Synchronization signal;

[0109] beacon signals;

[0110] Trigger signal;

[0111] Reader-to-device signal.

[0112] In some embodiments, the first device sends a first message to the second device, including: the first device determining the timing for initiating an access process based on the first configuration information and the timing information or signal.

[0113] Optionally, the first configuration information includes multiple available time resources. Based on the first configuration information and the timing information or signal, the first device selects or determines the timing for initiating the access procedure. At the timing for initiating the access procedure, the first device sends a first message to the second device.

[0114] Optionally, the first device determines the timing for sending the first message based on the first configuration information and the timing information or signal.

[0115] Optionally, the first device sends a first message to the second device, including at least one of the following:

[0116] The first device determines the timing for initiating the access process based on the first configuration information;

[0117] Based on the timing information or signal, the first device sends a first message to the second device when the time to initiate the access process arrives.

[0118] It is understood that the first device determines the timing for initiating the access process based on the time resources indicated by the first configuration information, and the first device sends a first message to the second device when the timing for initiating the access process arrives, based on the timing information or signal indicated by the second device.

[0119] In this embodiment, timing information or signals are used by the AIoT device to determine when to initiate the access process. The AIoT device does not need to include a clock module to support timing, which helps to reduce the cost of the AIoT device. Furthermore, based on timing information or signals, conflicts caused by multiple AIoT devices simultaneously and randomly initiating access processes can be reduced.

[0120] Optionally, before the AIoT device initiates the access process, the AIoT device receives first configuration information sent by the Reader. This first configuration information is used to provide the configuration required for the AIoT device to perform the access process.

[0121] Optionally, the first configuration information includes at least one of the following:

[0122] 1) Identification information of the first device;

[0123] This refers to the identifier of the AIoT device, used to identify the AIoT device during the access process. Optionally, it is used to identify the AIoT device within the Reader's scope.

[0124] 2) First filtering information, used to indicate at least one environmental IoT device that is allowed to initiate the access procedure;

[0125] It is understandable that the first filtering information is used to screen AIoT devices, or in other words, to select AIoT devices that are allowed to access the network.

[0126] Optionally, the first filtering information includes one of the following:

[0127] All bit information of the identification information of one or more environmental IoT devices;

[0128] Partial bit information of the identification information of one or more environmental IoT devices;

[0129] Group identification information for one or more groups of environmental IoT devices;

[0130] Memory information in environmental IoT devices.

[0131] In one implementation, the first filtering information includes information for comparison, and the relevant information of the AIoT device is selected if it matches the first filtering information.

[0132] In one implementation, the first filtering information may be the identifier of one or more AIoT devices, a group identifier of one or more groups of AIoT devices, or part or all of the bit information of the identifier of the AIoT devices.

[0133] In one implementation, the first filtering information includes memory information in the AIoT device, i.e., information stored in the AIoT device, which can be used to select or filter IoT devices in the environment.

[0134] In this embodiment, when there are many AIoT devices, by selecting the AIoT devices that are allowed to access, the number of AIoT devices that actively access can be efficiently controlled, access collisions can be reduced, and access resources can be effectively utilized.

[0135] Optionally, if the AIoT device is selected by the first filtering information, the AIoT device is allowed to initiate the access process.

[0136] 3) First access indication information, used to indicate whether the first device is allowed or not allowed to initiate an access procedure;

[0137] For example, the DO-A indication is used to indicate whether an AIoT device is allowed to initiate an access process.

[0138] 4) First wireless resource configuration information, used to configure the wireless resources available to the first device during the access process;

[0139] The first radio resource configuration information (AIoT Radio Resource Configuration) is used to configure the radio resources available to the AIoT device during the access process, that is, to configure access resources, including frequency resources and / or time resources (timing).

[0140] Frequency resources refer to the frequency resources on which the AIoT device transmits information.

[0141] Time resources, such as access timing, i.e., the time on which the AIoT device sends information.

[0142] Optionally, if first radio resource configuration information is configured, the first device is allowed to initiate an access procedure.

[0143] 5) First carrier configuration information, used to instruct the first device whether the second device should send or not send a carrier, and / or, the carrier frequency point, and / or, the carrier transmission method;

[0144] The carrier transmission method includes at least one of the following: continuous transmission (Always on), periodic transmission (periodic), or event-triggered transmission (Event-trigger).

[0145] Optionally, if first carrier configuration information is configured, the AIoT device is allowed to initiate an access procedure. Here, the AIoT device is a passive or semi-passive type AIoT device. Alternatively, the Reader supports the AIoT device initiating an access procedure.

[0146] Optionally, the AIoT device determines whether to listen to carriers and which carriers / carriers to listen to based on the judgment result of whether the frequency points carried in the first configuration information match the frequency points supported by its own capabilities.

[0147] Optionally, the method further includes:

[0148] If the carrier frequency point carried in the first configuration information matches the frequency point supported by the first device, the first device determines the monitoring carrier, or determines the monitoring carrier and the target carrier to be monitored.

[0149] In this embodiment, considering that the network configures and transmits carriers according to its supported capabilities or according to service requirements, there may be a mismatch between the carrier frequency carried in the first configuration information and the frequency supported by the AIoT device. In such cases, the AIoT device will not perform the carrier listening action. Therefore, the configuration of the carrier determines whether the AIoT device is allowed to initiate the access process.

[0150] 6) A first timing information indication, used to instruct the first device to send or not send timing information or signals to the second device;

[0151] Optionally, if a first timing information indicator is configured, or if the first timing information indicator instructs the first device to send timing information or signals to the second device, then the AIoT device is allowed to initiate an access procedure. In other words, the Reader supports the AIoT device initiating an access procedure.

[0152] Optionally, the AIoT device determines the timing for initiating the access process within the available time resources based on the aforementioned timing information.

[0153] 7) First trigger information indication, used to instruct the first device to send or not send a trigger signal, the trigger signal being used to trigger the first device to perform an access process.

[0154] Optionally, the method further includes:

[0155] When the first device detects the trigger signal from the second device, the first device determines whether to initiate an access process based on service requirements.

[0156] It is understandable that an AIoT device can initiate an access process after detecting a trigger signal from a second device. It is also understandable that an AIoT device can choose not to initiate an access process if it detects a trigger signal but has no need to.

[0157] Optionally, if a first trigger information indication is configured, the AIoT device is allowed to initiate an access procedure. In other words, the Reader supports the AIoT device initiating an access procedure.

[0158] Optionally, the first configuration information can be sent via dedicated signaling, i.e., the Reader sends it separately to the AIoT device.

[0159] In one implementation, after the AIoT device completes the random access process or inventory process, the AIoT device receives the first configuration information sent by the Reader. The first configuration information includes one or more of the following: the AIoT device identifier, first access indication information, first radio resource configuration information, first carrier configuration information, and first timing information indication.

[0160] The AIoT device stores the first configuration information.

[0161] If the AIoT device is allowed to initiate an access procedure, the AIoT device uses the saved first configuration information to initiate the access procedure based on backscattering of the carrier.

[0162] Optionally, the first configuration information can be sent via public signaling, i.e., the Reader sends it to multiple AIoT devices.

[0163] In one implementation, the AIoT device listens to the first configuration information sent by the Reader. The first configuration information includes one or more of the following: first filtering information, first access indication information, first radio resource configuration information, first carrier configuration information, and first timing information indication. The AIoT device stores the first configuration information.

[0164] If the AIoT device is allowed to initiate an access procedure, the AIoT device uses the saved first configuration information to initiate the access procedure based on backscattering of the carrier.

[0165] Optionally, the first device sends a first message to the second device, including:

[0166] The first device sends a first message on a target radio resource, the target radio resource being determined based on the first configuration information.

[0167] It is understandable that the first device determines the target radio resource based on the first configuration information. The target radio resource is determined according to the first configuration information, so the first device can send a D2R message, also known as the first message, to the second device on the configured radio resource (including frequency resources, access timing, etc.).

[0168] Optionally, the D2R (Device to Reader) message is used in the Command procedure. For example, an AIoT device acts as a sensor, and proactively reports business data to the Reader.

[0169] Figure 3 This is one of the interactive flow diagrams of the access method provided in the embodiments of this application.

[0170] One implementation method, referenced Figure 3 The access method includes: Step 301, the AIoT device receives first configuration information; Step 302, the AIoT device listens for a carrier wave; Step 303, the AIoT device receives or listens for timing information or signals, or the AIoT device receives or listens for trigger information or signals; Step 304, after the AIoT device listens for the carrier wave, it sends a D2R (Device to Reader) message to the Reader at the configured access timing based on the first configuration information. This implementation allows the second device to manage more AIoT devices and reduces access collisions between AIoT devices.

[0171] Another implementation method, see reference. Figure 3 The access method includes: step 302, the AIoT device listens for a carrier wave; step 304, after the AIoT device listens for the carrier wave, it sends a D2R (Device to Reader) message to the Reader. This implementation is suitable for situations where the carrier wave is always present and the AIoT is allowed to initiate active access at any time, which helps to simplify signaling.

[0172] Figure 4 This is a second schematic flowchart illustrating the access method provided in an embodiment of this application. Figure 4 As shown, the access method includes:

[0173] Step 410: The second device sends the first object;

[0174] Optionally, the second device is a reader. Optionally, the reader can be a terminal, an intermediate node, or a network-side device, that is, the second device can also be a terminal, an intermediate node, or a network-side device.

[0175] Due to issues such as self-interference, network-side devices, terminals, intermediate nodes, or assisting nodes can be multiple. For example, multiple readers can each handle either receiving or sending functions, thus supporting send-receive separation.

[0176] Optionally, the first object includes at least one of the following:

[0177] carrier wave;

[0178] Timing information or signals, wherein the timing information or signals are used to indicate time information or synchronization information;

[0179] First configuration information, which is used to indicate the configuration required for the first device to perform the access procedure.

[0180] The second device sends the first object, so that the first device can initiate an access process based on the first object.

[0181] Step 420: The second device receives a first message from the first device, the first message being used to initiate an access procedure;

[0182] Optionally, the first device is at least one of the following:

[0183] Passive, semi-passive, or active environmental AIoT devices;

[0184] AIoT devices are categorized by device type, which includes device 1, device 2a, or device 2b.

[0185] AIoT devices are categorized according to the supported communication types, which include Device Autonomous Initiated DO-A, Device Initiated DO-DTT triggered by device termination, or Device Termination DT.

[0186] Optionally, the first message is a Device to Reader (D2R) message.

[0187] Optionally, the first message includes at least one of the following:

[0188] The first message in the four-step random access process;

[0189] The first message in the two-step random access process;

[0190] The first message of a competition-based random access procedure;

[0191] The first message of a contention-free random access procedure.

[0192] It should be noted that the descriptions in the second device-side embodiments can be referred to the relevant descriptions in the aforementioned first device-side embodiments.

[0193] In some embodiments, the first message is transmitted based on the backscattering of the carrier, wherein the first device is a passive or semi-passive AIoT device.

[0194] It is understandable that passive or semi-passive devices, which have energy storage, can initiate the access process based on backscattering of a carrier wave. That is, AIoT devices do not send D2R messages after receiving Reader to Device (R2D) messages, but actively send D2R messages by backscattering the carrier wave sent by the second device to initiate the access process or transmit data.

[0195] Optionally, the carrier wave is transmitted continuously, periodically, or event-triggered.

[0196] In some embodiments, the carrier wave is transmitted by a second device (such as a Reader). The Reader can transmit the carrier wave as needed for services. Continuously transmitted carrier waves help reduce the latency for AIoT devices to initiate access. Periodically transmitting carrier waves by the Reader can support AIoT devices to periodically execute AIoT services; the Reader can also transmit carrier waves as needed for occasional services (i.e., event-triggered). Periodic or event-triggered carrier waves help the Reader save energy when transmitting carrier waves.

[0197] Optionally, the timing information includes at least one of the following:

[0198] Time information;

[0199] Frame number or time slot number.

[0200] Optionally, the timing information is carried via paging messages or query messages.

[0204] Trigger signal;

[0205] Reader-to-device signal;

[0206] Leader sequence.

[0207] Optionally, the timing signal includes one of the following:

[0208] Synchronization signal;

[0209] beacon signals;

[0210] Trigger signal;

[0214] First filtering information, the first filtering information being used to indicate at least one environmental IoT device that is permitted to initiate an access procedure;

[0215] The first access indication information is used to indicate whether the first device is allowed or not allowed to initiate an access process;

[0216] The first wireless resource configuration information is used to configure the wireless resources available to the first device during the access process.

[0217] The first carrier indication information is used to instruct the first device whether the second device should send or not send a carrier, and / or, the carrier frequency point, and / or, the carrier transmission method;

[0218] The first timing information indication is used to instruct the first device whether the second device should send or not send timing information or signals;

[0219] The first trigger information indication is used to instruct the first device whether the second device should send or not send a trigger signal, and the trigger signal is used to trigger the first device to perform an access process.

[0220] Optionally, the first filtering information includes one of the following:

[0221] All bit information of the identification information of one or more environmental IoT devices;

[0222] Partial bit information of the identification information of one or more environmental IoT devices;

[0223] Group identification information for one or more groups of environmental IoT devices;

[0224] Memory information in environmental IoT devices.

[0225] Optionally, the first configuration information is sent via dedicated signaling or public signaling.

[0226] For an understanding of the first configuration information, please refer to the description in the aforementioned first device-side method embodiment, which can achieve the same technical effect, and will not be repeated here.

[0227] Optionally, the method further includes:

[0228] The second device stores device context information, which is used to indicate information about the target environment IoT device that is allowed to initiate the access process.

[0229] It is understandable that the second device, during its interaction with AIoT, saves the context information of the target AIoT device that is allowed to initiate the access process.

[0230] Optionally, the device context information includes at least one of the following:

[0231] The identification information of the target environment IoT device, or the identification information of the group to which the target environment IoT device belongs;

[0232] The second filtering information is used to indicate the filtering information for selecting the target environment IoT device;

[0233] The second access indication information is used to indicate that the target environment IoT device is allowed to initiate an access process;

[0234] The second wireless resource configuration information is used to indicate the wireless resources that the target environment IoT device may use during the access process, such as frequency resources and time resources.

[0235] The second carrier configuration information is used to indicate whether the target environment IoT device needs or does not need a carrier, and / or, the carrier frequency points supported by the target environment IoT device, and / or, the transmission method of the required carrier;

[0236] The second timing information indication is used to indicate the possible timing when the target environment IoT device performs the access process;

[0237] Optionally, the second device may control the transmission of the carrier based on a second timing indication.

[0238] The second trigger information indication is used to indicate whether the target environment IoT device needs or does not need the second device to send a trigger signal, and the trigger signal is used to trigger the target environment IoT device to perform the access process.

[0239] In some embodiments, when the second device is a terminal, i.e., the second device is a UEreader, the method further includes:

[0240] The terminal receives second configuration information from the network-side device, the second configuration information being used to configure the second device to execute the access process initiated by the first device.

[0241] Figure 5 This is a second schematic diagram illustrating the interaction flow of the access method provided in this application embodiment. (See reference...) Figure 5 The access method includes: step 500, the UEreader receives second configuration information sent by the network-side device; step 510, the UEreader sends first configuration information to the AIoT device; step 520, the UEreader sends a carrier wave to the AIoT device; step 530, the UEreader sends timing information or a signal to the AIoT device; step 540, the UEreader receives a D2R message sent by the AIoT device, which is used to initiate the access process; and step 550, the UEreader reports AIoT data to the network-side device. Steps 510 and 530 are optional.

[0242] The second configuration information here can be called UE configuration information, which is used to configure the UEreader to execute the access process initiated by the AIoT device.

[0243] It is understandable that UEreader was chosen to communicate with AIoT devices.

[0244] Optionally, the second configuration information includes at least one of the following: device context information, which is used to indicate information about the target environment IoT device that is allowed to initiate an access procedure; all or part of the first configuration information; and third access indication information, which is used to indicate that the first device is allowed to initiate an access procedure to the second device.

[0245] For an understanding of the device context information and the first configuration information, please refer to the description in the foregoing embodiments.

[0246] Optionally, the device context information corresponds to an environmental IoT device, a group of environmental IoT devices, or a class of environmental IoT devices.

[0247] It is understandable that device context information can be defined for each AIoT device, a group of AIoT devices, or a class of AIoT devices.

[0248] Optionally, based on the previous embodiment, the method further includes:

[0249] The terminal excludes carrier frequency points that it does not support based on the second configuration information, and determines the carrier frequency points carried in the first configuration information.

[0250] That is, the carrier / frequency information in the first configuration information needs to be determined in conjunction with the UE Reader's wireless capabilities in the AIoT air interface. Optionally, before sending the first configuration information to the AIoT device, the UE Reader excludes frequency points that the UE does not support from the UE configuration information based on the UE's capabilities, such as the carrier frequency points supported by the UE, determines the content of the first configuration information to be sent to the AIoT device, and then sends the first configuration information to the AIoT device.

[0251] In this embodiment, when the UE Reader does not report the wireless capabilities of the AIoT air interface to the network-side device, this implementation method facilitates the UE in determining which carrier frequency(s) to operate on based on its capabilities. For scenarios involving non-RRC connectivity and UE mobility, this method is relatively simple, simplifying the process of negotiating AIoT resources between the UE and the network.

[0252] In some embodiments, before the terminal receives second configuration information from the network-side device, the method further includes:

[0253] The terminal reports its AIoT air interface wireless capability information to the network-side device, and the AIoT air interface wireless capability information includes at least one carrier frequency point supported by the terminal.

[0254] That is, the carrier / frequency information in the first configuration information needs to be determined in combination with the wireless capabilities of the UE Reader in the AIoT air interface. Optionally, before the network-side device sends the UE configuration information, the terminal reports the wireless capability information of the terminal's AIoT air interface to the network-side device. The wireless capability information of the AIoT air interface includes at least one carrier frequency point supported by the terminal.

[0255] Thus, the UE configuration information sent by the network-side device to the UE Reader matches the wireless capabilities of the UE Reader's AIoT air interface. That is, the carrier frequency carried in the second configuration information is determined based on the wireless capability information of the AIoT air interface, so the carrier that the UE Reader is requested to send is one that the UE Reader supports.

[0256] Optionally, the terminal is in RRC connected state. For UEs in RRC connected state, the UE Reader can easily report the wireless capabilities of the AIoT air interface to the network-side device and negotiate AIoT air interface resources such as carrier frequency points with the network.

[0257] Optionally, the method further includes:

[0258] The terminal sends data from the first device to the network-side device.

[0259] The method in this embodiment supports AIoT devices to initiate active access to UEreader, thereby enabling AIoT devices to initiate active access in a wider range of scenarios.

[0260] Figure 6 This is the third schematic diagram illustrating the interaction flow of the access method provided in this application embodiment. (See reference...) Figure 6 The access method includes:

[0261] Step 600: The first reader (Reader1) and the second reader (Reader2) receive the second configuration information sent by the network-side device; Step 610: Reader1 sends the first configuration information to the AIoT device; Step 620: Reader1 sends a carrier wave to the AIoT device; Step 630: Reader1 sends timing information or a signal to the AIoT device; Step 640: Reader2 receives a D2R message sent by the AIoT device, which is used to initiate an access procedure, or to initiate an access procedure and send data; Step 650: Reader2 reports AIoT data to the network-side device. Steps 610 and 630 are optional.

[0262] It should be noted that the first reader and the second reader are deployed separately, and the second configuration information is the Reader configuration information.

[0263] The first reader transmits R2D signals and a carrier wave; the second reader receives D2R signals.

[0264] Optionally, the first reader performs at least one of the following:

[0277] Device context information, which is used to indicate information about the target environment IoT device that is allowed to initiate the access procedure;

[0278] All or part of the first configuration information;

[0279] The third access indication information is used to indicate that the first device is allowed to initiate an access process to the second device.

[0280] Optionally, the device context information corresponds to an environmental IoT device, a group of environmental IoT devices, or a class of environmental IoT devices.

[0281] Optionally, the device context information includes at least one of the following:

[0282] The identification information of the target environment IoT device, or the identification information of the group to which the target environment IoT device belongs;

[0283] The second filtering information is used to indicate the filtering information for selecting the target environment IoT device;

[0284] The second access indication information is used to indicate that the target environment IoT device is allowed to initiate an access process;

[0285] The second wireless resource configuration information is used to indicate the wireless resources that the target environment IoT device may use during the access process;

[0286] The second carrier configuration information is used to indicate whether the target environment IoT device needs or does not need a carrier, and / or, the carrier frequency points supported by the target environment IoT device, and / or, the transmission method of the required carrier;

[0287] The second timing information indication is used to indicate the possible timing when the target environment IoT device performs the access process;

[0288] The second trigger information indication is used to indicate whether the target environment IoT device needs or does not need the second device to send a trigger signal, and the trigger signal is used to trigger the target environment IoT device to perform the access process.

[0289] For an understanding of the device context information and the first configuration information, please refer to the description in the foregoing embodiments, which will not be repeated here.

[0290] The method in this embodiment supports AIoT devices initiating access procedures to a separately deployed Reader, thereby enabling AIoT devices to initiate access under a separately deployed Reader.

[0291] The access method provided in this application supports passive AIoT devices initiating active access in various deployment scenarios. AIoT devices initiate the access process based on network or Reader configuration, reducing access collisions. Passive AIoT devices can initiate the access process based on pre-configuration and carrier waves, expanding the application scenarios of passive AIoT devices and making it possible for low-cost AIoT devices to support active access. The UE Reader supports active access methods for AIoT devices, including active access for passive or semi-passive AIoT devices. Separately deployed Readers support active access for AIoT devices.
