[0038] The access method, device, equipment and storage medium provided by the embodiments of the present application will be described in detail below in combination with the drawings, some embodiments and application scenarios.

[0039] FIG. 2 is a flowchart of an access method according to an embodiment of the present application. As shown in FIG. 2, the access method comprises:

[0040] Step 210, the first device listens to or receives a first object;

[0041] Optionally, the first device is at least one of the following:

[0042] Ambient IoT AIoT device of passive type, semi-passive type or active type;

[0043] AIoT device distinguished according to device type, wherein the device type includes device 1, device 2a or device 2b;

[0044] AIoT device distinguished according to supported communication type, wherein the communication type includes device autonomous initiation DO-A, device termination triggered device initiation DO-DTT, or device termination DT.

[0045] It can be understood that the first device is an AIoT device.

[0046] Ambient IoT, also known as Ambient power-enabled Internet of Things (AIoT for short), is a kind of IoT business. Among them, the AIoT device is powered by energy harvesting, and the AIoT device has no battery or has limited energy storage capacity (for example, using a capacitor). The overall power consumption of such devices is low, including low-power signal reception and low-power signal transmission. Due to the low overall power consumption, the communication energy can come from the environment, such as wind energy, kinetic energy, thermal energy, radio frequency RF signal, etc., which can also be called Ambient IoT device or passive IoT device or responder.

[0047] Ambient IoT devices can be categorized based on energy source, energy storage capability, passive or active transmission, etc. including various device types:

[0048] Passive Device, such as device 1. No energy storage, no independent signal generation / amplification capability, communication through backscattering.

[0049] Semi-passive Device, such as device 2a, also belongs to the large category of Passive Device. With energy storage, no independent signal generation, i.e. communication through backscattering. The stored energy can be used for amplification of the reflected signal.

[0050] Active Device, such as device 2b, with energy storage, with independent signal generation capability, i.e. containing active radio frequency components for transmission.

[0051] Different energy storage capabilities of devices also affect the transmission quality of the device. Generally, devices with higher energy storage also mean higher receiving sensitivity or higher sending power. That is, the reliability of the receiving or sending link can be better guaranteed.

[0052] The main data / service types of AIoT include:

[0053] DO: Device-originated, DO devices usually send various data, requests or instructions, i.e. initiated by the device itself;

[0054] DT: Device-terminated, DT devices usually receive instructions, data or requests from other devices or systems, i.e. terminated to the device;

[0055] Among them, DO data means that the data flow originates from the AIoT device (similar to RFID tag). DT data means that the data flow is transmitted to the AIoT device.

[0056] For data flow originating from AIoT device, i.e. DO data, it can be further classified as:

[0057] 1) DO-A: DO autonomous, i.e. AIoT device autonomously initiates data transmission.

[0058] For example, a large number of various sensors are connected, which collect and actively report information about the environment, devices and living beings when necessary.

[0059] 2) DO-DTT: Device-terminated triggered device-originated (DO device-terminated triggered), i.e., a reader device such as a base station triggers an AIoT device to initiate data transmission.

[0060] For example, asset identification, status reporting and tracking are all DL triggered reporting, and the reader collects data from the tag by triggering the inventory program. Since the AIoT device generates data and initiates data transmission, this service should be considered as a DO service triggered by the AIoT device initiated by the reader side control command.

[0061] According to the above device type, the first device can be an environment Internet of Things (AIoT) device of passive type, semi-passive type or active type.

[0062] The first device can be an AIoT device distinguished according to device type, including type 1 / 2a / 2b, etc.

[0063] The first device can be an AIoT device distinguished according to the supported communication type. Among them, the communication type includes: DT, DO-DTT, DO-A, etc.

[0064] Optionally, the second device is a reader. Optionally, the reader can be a terminal or an intermediate node or a network side device, i.e., the second device can also be a terminal or an intermediate node or a network side device.

[0065] Due to self-interference and other problems, the network side device, terminal, intermediate node or assisting node can be multiple network side devices, terminals, intermediate nodes or assisting nodes respectively. For example, multiple Readers respectively undertake the functions of receiving or transmitting, thereby supporting transceiver separation.

[0066] Optionally, the first device is a tag. It should be noted that in the Radio Frequency Identification (RFID) technology, the tag is a wireless radio device used for identifying and tracking objects. The RFID tag is composed of a chip and an antenna, and can communicate with the reader through wireless radio frequency signals. In the embodiments of the present application, the tag can also be used to refer to the AIoT device.

[0067] It should be noted that reader generally refers to a read-write device, a hardware device for capturing or reading and writing RFID tags, barcodes, QR codes, and other information. In this application, reader refers to a device capable of reading and writing information.

[0068] In the embodiments of the present application, reader can also be represented as:

[0069] Scanner: generally used to refer to a device for reading and writing barcodes or QR codes;

[0070] Reader: if the device has the functions of reading and writing and writing information at the same time.

[0071] RFID reader: if the reading and writing device for RFID technology is specified, this term can be used.

[0072] Inductor: in some cases, especially in RFID technology, "reader" can also be called inductor, because it senses the tag through wireless signal.

[0073] Optionally, the first object includes at least one of the following:

[0074] Carrier;

[0075] Timing information or signal, which is used to indicate time information or synchronization information.

[0076] First configuration information, which is used to indicate the configuration of the access procedure performed by the first device.

[0077] It can be understood that the first device receives or listens to the first object, and can obtain at least one of the carrier, the timing of initiating the access procedure by the first device, and the configuration of performing the access procedure.

[0078] Step 220, the first device sends a first message to the second device, and the first message is used to initiate an access procedure;

[0079] The first device receives or listens to the first object, and can obtain at least one of the carrier, the timing of initiating the access procedure by the first device, and / or the configuration of performing the access procedure, so that the access procedure can be initiated based on the carrier, the timing of initiating the access procedure by the first device, and / or the configuration of performing the access procedure.

[0080] Optionally, the first message is a device-to-reader (D2R) message.

[0081] Optionally, the first message includes at least one of the following:

[0082] The first message of the four-step random access procedure, such as Msg1.

[0083] a first message of a two-step random access procedure, such as MsgA;

[0084] a first message of a contention-based random access procedure;

[0085] a first message of a contention-free random access procedure.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] Optionally, the contention-free random access procedure can be a contention-free four-step random access procedure or a contention-free two-step random access procedure.

[0090] In some embodiments, the first message is transmitted based on backscattering of the carrier, wherein the first device is a passive type or semi-passive type AIoT device.

[0091] It can be understood that the passive device or semi-passive device can initiate the access procedure based on backscattering of the carrier. That is, the AIoT device does not send a D2R message after receiving a request message of a reader to device (R2D), but actively sends a D2R message by backscattering of the carrier to initiate the access procedure or transmit data.

[0092] Optionally, the carrier is continuously transmitted or periodically transmitted or event-triggered.

[0093] In some embodiments, the carrier is transmitted by a second device (such as a Reader). The Reader can transmit the carrier according to the business needs. The continuously transmitted carrier helps to provide more access opportunities, thereby reducing the latency of the AIoT device initiating access. The Reader periodically transmits the carrier, which can support the AIoT device to periodically perform AIoT business; the Reader can transmit the carrier according to the business sporadic needs (i.e., event-triggered). The periodically or event-triggered carrier helps the Reader to save the energy of transmitting the carrier.

[0094] Optionally, the first device initiates the access procedure, which can be an active initiation of the access procedure. The AIoT device can actively initiate the access procedure (DO-A) after detecting the carrier.

[0095] Optionally, the access procedure initiated by the first device can also be a passive initiation.

[0096] The access method provided by the embodiments of the present application enables the first device to listen to or receive the first object and send a first message for initiating an access procedure to the second device, so that the first device can initiate the access procedure based on the carrier, timing information or signal and / or first configuration information, thereby expanding the use scenarios of passive or semi-passive AIoT devices and enabling low-cost and low-power AIoT devices to support active access.

[0097] Optionally, before the AIoT device initiates the access procedure, the AIoT device receives timing information (Timing information) or listens to a timing signal. The AIoT device determines the timing of initiating the access procedure based on the timing information or the timing signal and the first configuration information.

[0098] Optionally, the timing information includes at least one of the following:

[0099] 1) Time information such as hours, minutes and seconds. It can be understood that the AIoT device initiates the access procedure at a specific time point. The AIoT device determines the specific time point according to the time information. Advantage: The AIoT device is a low-cost device and may not have a clock system, so it cannot determine the time autonomously and needs to determine the time point according to the timing information sent by the Reader.

[0100] 2) Frame number or time slot number. The AIoT device determines the current time according to the frame number or time slot number, thereby determining the timing of initiating the access procedure or determining whether the timing of initiating the access procedure is reached.

[0101] Optionally, the timing information is carried by a paging message or an inquiry message.

[0102] Optionally, the timing information is indicated by one of the following methods:

[0103] a synchronization signal;

[0104] a beacon signal;

[0105] a trigger signal;

[0106] a reader to device (R2D) signal;

[0107] a preamble.

[0108] For example, the AIoT device continuously monitors the synchronization signal and counts, so as to determine whether the time to initiate the access procedure is reached. Optionally, the synchronization signal is periodically transmitted.

[0109] Optionally, the timing signal comprises one of:

[0110] a synchronization signal;

[0111] a beacon signal;

[0112] a trigger signal;

[0113] a reader-to-device signal.

[0114] In some embodiments, the first device sends the first message to the second device, comprising: the first device determines the time to initiate the access procedure based on the first configuration information and the timing information or signal.

[0115] Optionally, the first configuration information comprises a plurality of available time resources, and the first device selects or determines the time to initiate the access procedure based on the first configuration information and the timing information or signal. The first device sends the first message to the second device at the time to initiate the access procedure.

[0116] Optionally, the first device determines the time to send the first message based on the first configuration information and the timing information or signal.

[0117] Optionally, the first device sends the first message to the second device, comprising at least one of:

[0118] the first device determines the time to initiate the access procedure based on the first configuration information;

[0119] the first device sends the first message to the second device at the time to initiate the access procedure based on the timing information or signal.

[0120] It can be understood that the first device determines the time to initiate the access procedure based on the time resource indicated by the first configuration information, and the first device sends the first message to the second device at the time to initiate the access procedure based on the timing information or signal indicated by the second device.

[0121] In the embodiments of the present application, the timing information or signal is used by the AIoT device to determine the time to initiate the access procedure, and the clock module for supporting timing does not need to be included on the AIoT device, which helps to reduce the cost of the AIoT device, and based on the timing information or signal, the conflict caused by multiple AIoT devices randomly initiating the access procedure at the same time can be reduced.

[0122] Optionally, before the AIoT device initiates the access procedure, the AIoT device receives first configuration information sent by the Reader. The first configuration information is used to provide the configuration required by the AIoT device to perform the access procedure.

[0123] Optionally, the first configuration information includes at least one of the following:

[0124] 1) identification information of the first device;

[0125] That is, the identification of the AIoT device, used to identify the AIoT device in the access procedure. Optionally, used to identify the AIoT device within the range of the Reader.

[0126] 2) first filtering information, used to indicate at least one environmental IoT device allowed to initiate the access procedure;

[0127] It can be understood that the first filtering information is used to screen the AIoT device, or in other words, to select the AIoT device allowed to access.

[0128] Optionally, the first filtering information includes one of the following:

[0129] All bit information of the identification information of one or more environmental IoT devices;

[0130] Part of the bit information of the identification information of one or more environmental IoT devices;

[0131] Group identification information of one or more groups of environmental IoT devices;

[0132] Memory information in the environmental IoT device.

[0133] In an embodiment, the first filtering information contains information for comparison, and the relevant information of the AIoT device matches the first filtering information, that is, the AIoT device is selected.

[0134] In an embodiment, the first filtering information can be the identification of one or more AIoT devices, the group identification of one or more groups of AIoT devices, or part or all of the bit information of the identification of the AIoT device.

[0135] In an embodiment, the first filtering information includes memory information in the AIoT device, that is, information stored in the AIoT device, which can be used to select or filter the environmental IoT device.

[0136] In the embodiments of the present application, in the case where there are many AIoT devices, by selecting the AIoT devices allowed to access, the number of AIoT devices actively accessing can be efficiently controlled, access collisions can be reduced, and access resources can be effectively utilized.

[0137] Optionally, if the AIoT device is selected by the first filtering information, the AIoT device is allowed to initiate an access procedure.

[0138] 3) first access indication information, used to indicate whether the first device is allowed or not allowed to initiate an access procedure;

[0139] As DO-A indicates, used to indicate whether the AIoT device is allowed to initiate an access procedure.

[0140] 4) first radio resource configuration information, used to configure the radio resources available to the first device in performing an access procedure;

[0141] The first radio resource configuration information (AIoT Radio Resource Configuration) is used to configure the radio resources available to the AIoT device in performing an access procedure, i.e., to configure access resources, including frequency resources and / or time resources (opportunity).

[0251] The terminal excludes a carrier frequency point not supported by the terminal according to the second configuration information, and determines the carrier frequency point carried in the first configuration information.

[0252] That is, the carrier / frequency information in the first configuration information is determined in combination with the wireless capability of the UE Reader on the AIoT air interface. Optionally, before the UE Reader sends the first configuration information to the AIoT device, the UE Reader excludes a frequency point not supported by the UE from the UE configuration information according to the UE capability, such as the carrier frequency point supported by the UE, determines the content of the first configuration information sent to the AIoT device, and then sends the first configuration information to the AIoT device.

[0253] In this embodiment, in the case where the UE Reader does not report the wireless capability of the AIoT air interface to the network side device, this implementation facilitates the UE to determine which carrier frequency point to work on according to the UE capability. For the scenario of non- RRC connected state and UE movement, this method is relatively simple, and simplifies the process of negotiating AIoT resources between the UE and the network.

[0254] In some embodiments, before the terminal receives the second configuration information from the network side device, the method further includes:

[0258] Optionally, the terminal is in an RRC connected state. For an RRC connected UE, the UE Reader can report the wireless capability of the AIoT air interface to the network side device, and negotiate the carrier frequency and other AIoT air interface resources with the network.
