[0143] FIG1A is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0144] As shown in FIG1A , a communication system 100 includes a first node 101 and a second node 102 .

[0145] In some embodiments, the first node 101 may be an A-IoT device, for example, the first node 101 may be an A-IoT device acting as a tag. In an A-IoT scenario, the first node 101 may include, but is not limited to, a device that sends data and / or signaling after being triggered by another device, such as a terminal or network device. The first node 101 may be equipped with a radio frequency identification (RFID) tag, and may be used as a reader by another device, such as a terminal or network device, to perform operations such as tag inventory and data reporting.

[0146] In some embodiments, the first node 101 may be an intermediate node, which may be located between the A-IoT device and the second node 102. When the first node 101 is an intermediate node, it may be any one of a relay node, an integrated access backhaul (IAB) node, a common terminal, and a repeater node.

[0147] Exemplarily, when the first node 101 is an ordinary terminal, it includes at least one of a mobile phone, a wearable device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and a wireless terminal device in a smart home, but is not limited thereto.

[0148] In some embodiments, the second node 102 may include but is not limited to a network device, such as at least one of an access network device and a core network device.

[0149] In some embodiments, the above-mentioned access network device is, for example, a node or device that accesses an ordinary terminal or an intermediate node to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

[0150] In some embodiments, the above-mentioned access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, and the functions of some protocol layers are centrally controlled by the CU, while the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU, but is not limited to this.

[0151] In some embodiments, the core network device may be a single device including one or more network elements, or may be multiple devices or a group of devices. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

[0152] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0153] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0154] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0155] Currently, various Low Power Wide Area (LPWA) technologies, such as Machine Type Communication (MTC), Narrow Band Internet of Things (NB-IoT), and Reduced Capability (RedCap), have been proposed to meet the growing needs of vertical fields. These LPWA technologies achieve low cost, low power consumption, and large-scale connectivity, meeting the requirements of many applications.

[0156] However, there are still many use cases and applications that cannot be addressed in the following scenarios.

[0157] First, devices powered by traditional batteries are not suitable for use in extreme environmental conditions (e.g., high voltage, extremely high / low temperatures, humid environments). Second, maintenance-free devices are required (e.g., traditional batteries that do not need to be replaced). Finally, ultra-low complexity, very small device size / form factor (e.g., mm thickness), and extended life cycle are required.

[0158] Ambient-powered IoT is a promising technology that can address the aforementioned unmet needs. An ambient-powered IoT device is an IoT device powered by energy harvesting, either without a battery or with limited energy storage capabilities (e.g., using capacitors), by harvesting radio waves, light, motion, heat, or any other suitable power source.

[0159] Energy harvested from the environment can power data transmission and wireless communications at sensor nodes. Current mainstream low-power IoT communication chips (such as Bluetooth BLE, LoRa, and NB-IoT) consume tens or even hundreds of milliwatts of power for both transmission and reception. Environmental energy harvesting, however, only captures microwatts of energy, making it inadequate for these types of nodes. Therefore, new wireless communication technologies are needed to reduce communication energy consumption to tens or even below ten microwatts. Backscatter communication is currently the mainstream approach. Backscatter communications is a key technology for building a green, energy-efficient, and flexibly deployable future IoT, and a crucial means of achieving the "intelligent connection of everything."

[0160] Backscatter communication utilizes the principle of RF signal backscattering to develop an extremely low-power modulation and transmission technology. Since a portion of the RF signal is reflected when it reaches the surface of an object, the transmitting node adjusts the matching between the receiving antenna and the impedance according to the intended information, enhancing the reflection of the incident RF signal and modulating the acquired sensory data onto the reflected signal to complete the data transmission. This process is similar to a reflector. Compared to other communication technologies, backscatter communication does not require a complex RF structure, reducing the use of components such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters. It also does not require complex baseband processing, thus simplifying terminal design and significantly reducing terminal node costs.

[0161] Backscatter communication is widely used in RFID (radio frequency identification) systems. Its operating principle, as shown in Figure 1B, involves a receiver (typically an RFID reader) transmitting a radio frequency excitation signal to activate a passive node (typically an RFID tag). The passive node then uses backscatter communication to modulate its own information onto the radio frequency signal. The reader then receives the passive tag's backscatter signal and demodulates it, enabling information transmission.

[0162] Currently, RFID technology still needs improvement, including limited coverage distance (the wireless signal experiences double-path fading during the communication process, resulting in high path loss and a short effective communication range), single-channel transmission, the need for strict tag alignment, and the lack of power control. RFID technology still has significant room for improvement in communication.

[0163] New IoT devices, such as passive IoT devices, have low memory, low processing power, low battery consumption, small data transmission capacity, and can be deployed in large quantities. Environmental IoT devices can be maintenance-free and have a long service life, for example, exceeding 10 years.

[0164] These new IoT devices require energy from radio waves transmitted by network nodes to power themselves. Therefore, until they receive energy, they are typically powered off, meaning they are disconnected from the network. To address this, the communication system must support data communication methods with shorter transmission times, lower memory consumption, and more convenient terminal management to expedite data communication.

[0165] Currently, the topology of an A-IoT system is shown in FIG1C , and includes at least one of the following topologies:

[0166] Topology 1: A-IoT devices and base stations directly receive and transmit uplink and downlink data.

[0167] In Topology 2, the A-IoT device and the base station indirectly receive and transmit uplink and downlink data. There are intermediate nodes between the A-IoT device and the base station for forwarding. For example, the intermediate nodes can be relays, IABs, UEs, and repeaters.

[0168] In Topology 3, A-IoT devices and base stations directly transmit or receive data in the downlink or uplink. Auxiliary nodes are deployed in the uplink or downlink, responsible for receiving or sending uplink data or receiving downlink data. Examples of auxiliary nodes include relays, IABs, UEs, and repeaters.

[0169] Topology 4: A-IoT devices and terminals directly receive and transmit uplink and downlink data; terminals are responsible for collecting data and forwarding it to network devices, such as base stations.

[0170] In some embodiments, A-IoT devices may include, but are not limited to, the following types:

[0171] Type 1, with energy storage, no independent signal generation / amplification, and uplink transmission relies on backscatter transmission.

[0172] Type 2 has energy storage and independent signal amplification. Uplink transmission can be generated inside the device or rely on backscatter transmission.

[0173] In a passive IoT system, there are three types of data transmission by A-IoT devices, including:

[0174] Type 1, based on network demand reporting data, such as inventory counts (DO-DTT).

[0175] Type 2, based on environmental IoT triggers, for example, the sensor’s temperature is higher than the configured threshold (DO-A).

[0176] Type 3: Network-triggered data reading and writing. For example, network-based periodic requests to implement regular environmental IoT data reporting (DT).

[0177] To support data transmission between A-IoT devices, a device in the network can support one or more functions:

[0178] 1. Function as an Energy Source (ES) for device type 2.

[0179] 2. Downlink transmission (DT) function, sending indication information to the A-IoT device, thereby triggering the uplink transmission of the A-IoT device.

[0180] 3. Continuous Wave (CW) excitation is used for device types 1 and 2. A-IoT devices achieve uplink transmission by backscattering CW. CW is actually a type of ES, and A-IoT devices can receive CW and store energy.

[0181] 4. Uplink reception (UR) function: receiving uplink information backscattered by A-IoT devices, or receiving uplink information actively transmitted by A-IoT devices.

[0182] The device that performs the ES, DT, CW, or UR functions described above may be a common terminal, repeater, relay, or base station. A device may support only one of the above functions. Alternatively, a device may support multiple of the above functions simultaneously. Alternatively, a device may support all of the above functions simultaneously.

[0183] In RFID communication systems, commands are divided into three functional categories: tag Select, Inventory, and Access. There are five inventory commands: Query, QueryAdjust, QueryRep, Acknowledge (ACK), and Negative Acknowledge (NACK).

[0184] For example, after a tag receives a valid Query command, each tag selected according to the set criteria generates a random number (similar to rolling a dice), and each tag with a random number of zero will generate an echo and move to the Reply state; tags that meet other conditions will change certain attributes and flags, thereby exiting the above tag group, which is conducive to reducing duplicate identification.

[0185] For example, after receiving a valid QueryAdjust command, each tag generates a new random number (similar to re-rolling a dice), and the rest is the same as Query.

[0186] For example, after receiving a valid QueryRep command, the tag only reduces the original random number of each tag in the tag group by one, and the rest is the same as Query.

[0187] For example, only a single tag can receive a valid ACK command and respond with a reply including an Electronic Product Code (EPC).

[0188] For example, after receiving a valid NACK command, the tag switches to the Arbitrate state except for the Ready or Killed states where the state remains unchanged.

[0189] In some embodiments, the A-IoT server is a service device or computing platform used to manage, process, and store Ambient IoT business data collected from the surrounding environment. It may be a physical server or a virtual server, located locally (for example, in a smart home system) or in the cloud, providing data processing and storage services, as well as possible other functions such as user interface, data visualization, remote access, and integration with third-party services or applications.

[0190] In order to improve the availability and reliability of A-IoT technology, the present disclosure provides the following information transmission method and device, and storage medium.

[0191] FIG2A is an interactive diagram of an information transmission method according to an embodiment of the present disclosure. As shown in FIG2A , the present disclosure embodiment relates to an information transmission method, which includes:

[0192] Step S2100: The first node 101 sends second indication information to the second node.

[0193] In some embodiments, the first node 101 may be an A-IoT device.

[0194] In some embodiments, the first node 101 may be an intermediate node located between the A-IoT device and the second node 102 .

[0195] In some embodiments, the second node 102 is a network device, such as an access network device, a core network device, or an A-IoT server.

[0196] In some embodiments, the second indication information may be used to indicate that the first node 101 has the capability of accessing the second node based on the first information.

[0197] In some embodiments, the second node 102 receives the second indication information.

[0198] Step S2101 : The second node 102 sends first information to the first node 101 .

[0199] In some embodiments, the first information is specific information associated with the first node 101 .

[0200] In some embodiments, the first information may include, but is not limited to, first configuration information.

[0201] In some embodiments, the first configuration information may include, but is not limited to, at least one of the following:

[0202] First Random Access Channel (RACH) configuration;

[0203] A first access control parameter.

[0204] In one example, the first RACH configuration is a RACH configuration dedicated to the first node 101 .

[0205] Exemplarily, the first RACH configuration may include but is not limited to at least one of the following:

[0206] First RACH resource configuration;

[0207] First RACH priority parameter configuration.

[0208] The first RACH resource configuration may include but is not limited to at least one of the following: two-step RACH resource configuration; four-step RACH resource configuration.

[0209] It can be understood that the first RACH resource configuration is a RACH resource configuration dedicated to the first node 101, the two-step RACH resource configuration can configure the RACH resource when the first node 101 uses the two-step random access method to access the second node 102, and the four-step RACH resource configuration can configure the RACH resource when the first node 101 uses the four-step random access method to access the second node 102.

[0210] The first RACH priority parameter configuration may include but is not limited to at least one of the following:

[0211] The first power ramping step (powerRampingStepHighPriority);

[0212] The first fallback indicates a scaling factor (scalingFactorBI).

[0213] The first access control parameter may include but is not limited to at least one of the following:

[0214] First access scaling factor;

[0215] First access waiting time;

[0216] First permission information and / or first prohibition information.

[0217] The first access control parameter may be an access control parameter dedicated to the first node 101 .

[0218] In step S2102 , the first node 101 accesses the second node 102 based on the first information.

[0219] In some embodiments, the first information includes the above-mentioned first configuration information.

[0220] In some embodiments, when initiating random access, the first node 101 may receive a RACH resource configuration sent by the second node 102 and, based on existing protocol procedures and rules, preferentially select the first RACH resource configuration associated with the first node 101 to initiate random access.

[0221] Exemplarily, the first node 101 may determine, based on the characteristic indication information of the RACH resource configuration sent by the second node 102, that the RACH resource configuration is associated with the first node, and the RACH resource configuration is the first RACH resource configuration.

[0222] It should be noted that the fact that the first node 101 preferentially selects the first RACH resource configuration associated with the first node 101 does not mean that the first node 101 can select the first RACH resource configuration when there is an available first RACH resource configuration. The first node 101 needs to make a judgment and selection based on other characteristics, and the specific method is not described here.

[0223] In the embodiment of the present disclosure, the first node 101 initiates random access based on the first RACH resource configuration. On the one hand, this can ensure that the first node 101 can access based on dedicated resources and ensure the access process. On the other hand, it can also enable the second node 102 to determine the attributes of the first node based on the first RACH resource, thereby performing reasonable configuration and preferentially ensuring the access of the first node 101.

[0224] Exemplarily, when there are multiple optional RACH priority parameter configurations, the first node 101 may determine whether to use a first RACH priority parameter configuration dedicated to the first node 101 .

[0225] Exemplarily, when the first node 101 initiates random access, the selected RACH configuration is configured with a first RACH priority parameter configuration, and the first node 101 may use the first RACH priority parameter configuration to perform random access.

[0226] Furthermore, if there are other available RACH priority parameter configurations for the first node 101, such as a second RACH priority parameter configuration determined according to an access identifier or a network slice grouping (NSAG), the first node 101 can determine whether to apply the priority of the first RACH priority parameter configuration based on the instructions of the second node 102 or the protocol agreement, and then determine whether to ultimately use the first RACH priority parameter configuration.

[0227] Assume that the second node 102 instructs or the protocol stipulates that the first node 101 should preferentially use the dedicated first RACH priority parameter configuration for random access. In this case, the first node 101 may determine the priority of applying the first RACH priority parameter configuration.

[0228] In an example, the first configuration information includes a first access control parameter, and the first node 101 may perform access control based on the first access control parameter so as to preferentially access the second node 102 .

[0229] Exemplarily, the first node 101 may determine access information, which may include an access type and / or an access identifier. The access type and / or access identifier may be specific to the first node, such as introducing a new access type and / or a new access identifier for the first node 101.

[0230] Exemplarily, the access information may be determined by a non-access stratum (NAS) of the first node 101 .

[0231] Exemplarily, the access information may be determined by an access stratum (AS) of the first node 101. The AS may include, but is not limited to, a medium access control (MAC) layer and a radio resource control (RRC) layer.

[0232] Exemplarily, the access information may be determined jointly by the NAS and AS of the first node 101 .

[0233] In an example, the access type and the access identifier may be determined by the NAS of the first node 101 .

[0234] In an example, the access type and the access identifier may be determined by the AS of the first node 101 .

[0235] In an example, the access type may be determined by the NAS of the first node 101 , and the access identifier may be determined by the AS of the first node 101 .

[0236] In an example, the access type may be determined by the AS of the first node 101 , and the access identifier may be determined by the NAS of the first node 101 .

[0237] In an example, the first node 101 may determine the corresponding first access control parameter based on the access information.

[0238] For example, the first node 101 may determine the corresponding first access control parameter based on the access type.

[0239] For another example, the first node 101 may determine the corresponding first access control parameter based on the access identifier.

[0240] For another example, the first node 101 may determine the corresponding first access control parameter based on the access type and the access identifier.

[0241] In an example, the first node 101 may perform access control based on the first access control parameter.

[0242] The first node 101 may access the second node 102 in priority over common terminals based on the first access control parameter.

[0247] In some embodiments, the information transmission method involved in the embodiments of the present disclosure may include at least one of steps S2100 to S2102. For example, step S2100 can be implemented as an independent embodiment, step S2101 can be implemented as an independent embodiment, step S2102 can be implemented as an independent embodiment, and steps S2101+S2102 can be implemented as independent embodiments, but are not limited thereto.

[0248] In some embodiments, step S2100 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, if second node 102 assumes that first node 101 has the capability to access second node 102 based on the first information, step S2100 may not be performed. For another example, if first node 101 does not have the aforementioned capability, step S2100 may not be performed.

[0249] In some embodiments, step S2101 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when the first node 101 sends the first information to the second node, step S2101 may not be performed.

[0250] In some embodiments, step S2102 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when the second node performs access control, step S2102 may not be performed.

[0251] In some embodiments, steps S2100 to S2102 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0252] In some embodiments, the execution order of steps S2100 to S2102 is not limited.

[0253] In the above embodiment, a first node can receive first information sent by a second node, thereby accessing the second node based on the first information, where the first information is proprietary information associated with the first node. The present disclosure can reduce the latency of the first node accessing the second node, thereby improving the availability and reliability of A-IoT technology.

[0254] FIG2B is an interactive diagram of an information transmission method according to an embodiment of the present disclosure. As shown in FIG2B , the present disclosure embodiment relates to an information transmission method, which includes:

[0255] Step S2200: The first node 101 sends second indication information to the second node.

[0256] The specific implementation method is similar to step S2100 and will not be repeated here.

[0257] Step S2201: The first node 101 sends first information to the second node 102.

[0258] In some embodiments, the first node 101 may be an A-IoT device.

[0259] In some embodiments, the first node 101 may be an intermediate node located between the A-IoT device and the second node 102 .

[0260] In some embodiments, the second node 102 is a network device, such as an access network device, a core network device, or an A-IoT server.

[0261] In some embodiments, the first information is specific information associated with the first node 101 .

[0262] In some embodiments, the first information includes first indication information, and the first indication information can be used to indicate the reason why the first node 101 accesses the second node 102 .

[0263] In one example, the access reason may include at least one of the following:

[0264] There is first data to be transmitted, where the first data comes from the A-IoT device;

[0265] A-IoT features.

[0266] In one example, the access reason may be determined by the NAS and / or AS of the first node 101 .

[0267] For example, as shown in Figure 2C , first node 101 is an intermediate node that receives a MAC CE sent by an A-IoT device, which includes feedback data for an inventory or read command. First node 101 can determine the access reason through the AS, such as the MAC layer, or instruct the RRC layer to determine the access reason. After determining the access reason, first node 101 can send the access reason to second node 102 via an RRC message or MAC CE carrying first indication information. In this case, the access reason may be the presence of first data to be transmitted, where the first data originates from the A-IoT device.

[0268] For example, as shown in FIG2D , there is an RRC layer in the protocol stack, and the first node 101 is an intermediate node. The first node 101 receives an RRC message sent by the A-IoT device through the RRC layer, which includes inventory or read command feedback data, etc. The RRC layer of the first device 101 can determine the access reason or indicate it to the NAS, which determines the access reason. Further, the first node 101 can send an RRC message to the second node 102, including first indication information, to inform the second node 102 of the access reason. In this case, the access reason can be the existence of first data to be transmitted, and the first data comes from the A-IoT device.

[0269] Exemplarily, the protocol stack architecture includes NAS, and the first node 101 is an intermediate node. It receives an RRC message sent by an A-IoT device, which includes a NAS container. The NAS container includes inventory or read command feedback data, etc. The RRC layer of the first node 101 can determine the access reason or indicate to the NAS to determine the access reason. Furthermore, the first node 101 can send an RRC message to the second node 102, including first indication information, to inform the second node 102 of the access reason. In this case, the access reason can be the existence of first data to be transmitted, and the first data comes from the A-IoT device.

[0270] Exemplarily, the first node 101 is an A-IoT device, and its RRC layer or NAS can determine the access reason, which can be indicated to the second node 102 through an RRC message. The access reason can indicate the A-IoT characteristics of the node.

[0271] The above description is merely an exemplary description, and the present disclosure does not limit the architecture of the protocol stack or the method of determining the access reason.

[0272] In step S2202 , the first node 101 accesses the second node 102 based on the first information.

[0273] In some embodiments, the second node 102 may perform access control based on the first information to ensure that the first node 101 can access the second node 102 preferentially compared to other common terminals.

[0274] In one example, when initiating RRC connection establishment or RRC connection recovery, the first node 101 may send first indication information to the second node 102, thereby informing the second node 102 of the access reason. When the network is congested, the second node 102 may determine, based on the access reason, that the first node 101 is an A-IoT device or that there is first data to be transmitted. In this case, the second node 102 may determine not to reject or release the RRC connection of the first node 101 in response to the RRC connection establishment / recovery request initiated by the first node 101.

[0275] The above description is merely an exemplary description, and all solutions in which the second node 102 performs access control based on access reasons should fall within the scope of protection of this disclosure.

[0276] In some embodiments, the information transmission method involved in the embodiments of the present disclosure may include at least one of steps S2200 to S2202. For example, step S2200 can be implemented as an independent embodiment, step S2201 can be implemented as an independent embodiment, step S2202 can be implemented as an independent embodiment, and steps S2201+S2202 can be implemented as independent embodiments, but are not limited thereto.

[0277] In some embodiments, step S2200 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, if the second node 102 assumes that the first node 101 has the capability to access the second node 102 based on the first information, step S2200 may not be performed. For another example, if the first node 101 does not have the aforementioned capability, step S2200 may not be performed.

[0278] In some embodiments, step S2201 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when the second node 102 sends the first information to the first node 101, step S2201 may not be performed.

[0279] In some embodiments, step S2202 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when the first node 101 performs access control, step S2202 may not be performed.

[0280] In some embodiments, steps S2201 to S2202 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0281] In some embodiments, the execution order of steps S2201 to S2202 is not limited.

[0282] In the above embodiment, a first node can send first information to a second node, thereby accessing the second node based on the first information, where the first information is proprietary information associated with the first node. The present disclosure can reduce the latency of the first node accessing the second node, thereby improving the availability and reliability of A-IoT technology.

[0341] FIG3D is an interactive diagram of an information transmission method according to an embodiment of the present disclosure. As shown in FIG3D , the present disclosure embodiment relates to an information transmission method, which can be executed by the second node 102. The method includes:

[0342] Step S3400: Obtain second indication information.

[0343] In some embodiments, the second node 102 may obtain the second indication information from the first node 101, but is not limited thereto. The second node 102 may also receive the second indication information sent by other entities.

[0348] Step S3401: Send or obtain first information.

[0349] The specific implementation process is similar to step S3201 and will not be repeated here.

[0350] In the above embodiment, the second node can receive the second indication information sent by the first node and, upon determining that the first node has the ability to access the second node based on the first information, send or obtain the first information. This disclosure can reduce the latency of the first node accessing the second node and improve the availability and reliability of A-IoT technology.

[0351] The above content is further illustrated below with examples.

[0352] In the embodiment of the present disclosure, for any of the above topology 1-4 scenarios, compared with ordinary terminal access, taking into account the latency requirements of A-IoT tasks and the particularity of immediate terminals (immediate UEs) due to the need to perform inventory tasks and data reporting, priority access of A-IoT devices can be guaranteed.

[0353] In some embodiments, the first node 101 may receive a dedicated access configuration sent by the second node 102 and initiate random access based on the dedicated access configuration to achieve fast access. The dedicated access configuration includes at least one of an access priority parameter or a dedicated access resource configuration.

[0354] In some embodiments, the first node 101 sends an access reason to the second node 102, where the access reason is used by the second node 102 to ensure high-priority access of the first node 101. The access reason may be transmitting data received from an A-IoT device or indicating an A-IoT feature of the node.

[0355] In some embodiments, a new access type or access identifier is defined for the access of the first node 101. When the intermediate node accesses, the AS / NAS selects the new access type or access identifier and receives the corresponding access control information sent by the second node 102 to perform access control. The corresponding access control information ensures high-priority access of the intermediate node.

[0356] In the embodiment of the present disclosure, the process is as follows:

[0357] 1. During the storage or data reading and writing process, the first node 101 preferentially accesses the second node 102 according to the first information.

[0358] In one possible implementation, the first node 101 may be a terminal.

[0359] 2. Based on 1, the first information includes first configuration information, and the preferentially accessing the second node 102 according to the first information includes:

[0360] Receive first configuration information sent by the second node 102, where the first configuration information is dedicated to the first node 101 to ensure priority access of the first node 101.

[0361] 3. Based on 2, the first configuration information sent by the second node 102 includes at least one of the following:

[0362] Dedicated RACH configuration, including dedicated RACH resource configuration and / or dedicated RACH priority parameter configuration;

[0363] Dedicated access control parameters.

[0364] 4. Based on 3, the dedicated RACH resource configuration includes two-step (2-step) and four-step (4-step) RACH resource configuration, and the resource configuration is associated with the first node 101.

[0365] In one possible implementation, when the first node 101 initiates random access, it receives the RACH resource configuration sent by the second node 102, and based on existing protocol processes and rules, preferentially selects the RACH resource configuration associated with the first node 101 (for example, determining that the RACH configuration is associated with the A-IoT intermediate node based on characteristic indication information of the RACH resource configuration) to initiate random access.

[0366] It should be noted that giving priority to the RACH resource configuration associated with the first node 101 does not mean that the first node 101 can select it when there is an available proprietary configuration. It is also necessary to make a judgment and selection based on other characteristics. The specific rules can be referred to the existing protocol process and will not be described here.

[0367] In addition, the first node 101 initiates random access based on the dedicated RACH resource. On the one hand, it can ensure that the intermediate node can access based on the dedicated resource and ensure the access process. On the other hand, it can also enable the network side to determine the node attributes based on the dedicated RACH resource, thereby performing reasonable configuration and giving priority to access.

[0368] 5. Based on 3, the dedicated RACH priority parameter configuration includes a power ramping step (powerRampingStepHighPriority) and a fallback indication scaling factor (scalingFactorBI) applied to the first node 101 for priority access.

[0369] Further, the second node 102 indicates first information, where the first information is used by the first node 101 to determine whether to use the dedicated RACH priority parameter configuration when there are multiple RACH priority parameter configurations.

[0370] In one possible implementation, when the first node 101 initiates random access, the selected RACH configuration is configured with the dedicated RACH priority parameter configuration, and the first node 101 may use the dedicated RACH priority parameter configuration for random access. Furthermore, if other RACH priority parameter configurations are available for the intermediate node, such as a RACH priority parameter configuration determined based on an access identifier or an NSAG, the first node 101 determines the priority of applying the dedicated RACH priority parameter configuration based on the first information indicated by the network or agreed upon by the protocol, and then determines whether to ultimately use the RACH priority parameter configuration dedicated to the first node 101. For example, the network indicates or the protocol stipulates that for the first node 101, the dedicated RACH priority parameter configuration of the first node 101 is preferentially used for random access.

[0371] 6. Based on 3, the dedicated access control parameter is associated with the first node 101. The step of preferentially accessing the second node 102 according to the first information includes:

[0372] Receive the dedicated access control parameter sent by the second node 102, and perform access control based on the dedicated access control parameter.

[0373] 7. Based on 6, performing access control based on the dedicated access control parameter includes determining an access type and / or access identifier of the first node 101, where the access type and / or access identifier is used to determine the dedicated access control parameter. The access type and / or access identifier may be newly introduced for the first node 101, and may be determined by an AS (e.g., MAC or RRC) and / or NAS.

[0374] 8. Based on 1, the first information includes access reason indication information, where the access reason may be transmitting data received from an A-IoT device or indicating an A-IoT characteristic of a node. Prioritizing access to the second node 102 based on the first information includes:

[0375] The first node 101 sends the access reason indication information to the second node 102 , so that the second node 102 performs access control according to the access reason indication information to ensure priority access of the first node 101 .

[0376] In one possible implementation, when initiating RRC connection establishment or RRC connection recovery, the first node 101 sends the access cause indication information to the second node 102, so that the second node 102 performs access control according to the access cause indication information to ensure priority access of the first node 101. For example, when the network is congested, the second node 102 determines that the node is an A_IOT intermediate node or has transmittable A-IoT data based on the access cause indication information, and determines to respond to the RRC connection establishment / recovery request without rejecting or releasing the RRC connection of the intermediate node.

[0377] 9. Based on 8, the access reason can be determined by information provided by the NAS layer or determined by the AS (for example, MAC, RRC).

[0378] In one possible implementation, in response to the MAC layer of the first node 101 receiving inventory or read command feedback data sent by the A-IoT device via a MAC CE, the MAC layer of the first node 101 may determine an access reason or indicate to a higher layer (e.g., RRC or NAS) to determine the access reason. The access reason may be indicated to the second node 102 via an RRC message or a MAC CE. The access reason may be the transmission of data received from the A-IoT device. The optional interaction between the MAC-RRC and AS-NAS layers is not further described.

[0379] In one possible implementation, the protocol stack architecture includes an RRC layer. In response to the RRC layer of the first node 101 receiving inventory or read command feedback data sent by the A-IoT device via RRC, the RRC layer of the first node 101 may determine an access reason or indicate it to the NAS for determination. The access reason may be indicated to the second node 102 via an RRC message. The access reason may be the transmission of data received from the A-IoT device. Optional interactions between the AS and NAS layers are not further described.

[0380] In one possible implementation, the protocol stack architecture includes NAS. In response to the RRC layer of the first node 101 receiving a NAS container (including inventory or read command feedback data, etc.) sent by the A-IoT device via RRC, the RRC layer of the first node 101 may determine an access cause or indicate it to the NAS for determination. The access cause may be indicated to the second node 102 via an RRC message. The access cause may be the transmission of data received from the A-IoT device. Optional interactions between the AS and NAS layers are not described in detail.

[0381] In one possible implementation, in response to the first node 101 having the capability or requirement to serve as an A-IoT intermediate node, that is, the first node 101 may be an A-IoT device capable of accessing the second node 102, its RRC layer or NAS layer may determine an access reason, which may be indicated to the second node 102 via an RRC message. The access reason may indicate the A-IoT characteristics of the first node 101. Optional AS-NAS layer interactions are not further described.

[0382] 10. Based on 1, in order to support priority access to the second node 102 based on the first information, the first node 101 optionally sends capability indication information to the second node 102 to indicate whether it has the capability.
