Description

Technical Field

[0001] This invention relates to the field of communications, and more particularly to an information transmission method, apparatus, device, storage medium, and product. Background Technology

[0002] In recent years, the Internet of Things (IoT) has received considerable attention in the field of wireless communication. With the large-scale application of IoT technology in various consumer terminals and industries, AIoT (Ambient Internet of Things, based on cellular networks) has emerged. "Passive" means that the terminal node devices connected to the network do not require an external power source or batteries. They obtain energy from the environment to achieve backscattering or autonomous signal generation, supporting a range of capabilities such as data sensing, wireless transmission, and distributed computing. In existing AIoT technologies, the A-IoT device and the base station accessing the core network are connected via the A-IoT air interface, such as... Figure 1 As shown, the base station can be viewed as a reader, performing inventory and command processes on the A-IoT device. However, for A-IoT devices located far from the base station, due to the limited transmission distance of the base station, some A-IoT devices may not be found, preventing the core network from performing inventory and command operations on these devices.

[0114] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0115] See Figure 2 , Figure 2 This is a schematic diagram of information transmission between a base station and an A-IoT device provided in an embodiment of the present invention. In order to solve the problem that the existing base station's transmission distance is insufficient, resulting in the inability to detect A-IoT devices at a greater distance, this embodiment of the present invention provides a new information transmission method, which is achieved by adding an intermediate device between the base station and the A-IoT device. This intermediate device can forward the coverage area between the base station and the A-IoT device, realize the core network's inventory and command operations on the A-IoT device, enhance the base station's capabilities, and avoid situations where the base station cannot find the A-IoT device.

[0116] Furthermore, since an intermediate device is added between the base station and the A-IoT device, the information exchange between the core network and the intermediate device includes the following two methods (the two methods will be described in detail below):

[0117] Method 1: The core network directly sends NAS (Non-Access Stratum) messages to intermediate devices;

[0118] Method 2: The core network sends messages to the base station, and the base station sends messages to intermediate devices.

[0119] The first device described in this embodiment of the invention is the intermediate device. The first device may be an access terminal, user equipment (UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. Further, it may be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, satellite handheld terminal, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, terminal device in a 5G network, or terminal device in a future evolved network, etc.

[0120] The second device is the A-IoT device, such as an Electronic Toll Collection (ETC) system, smart home products, logistics monitoring equipment, etc.

[0121] The third device may be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, a Next Generation Radio Access Network (NGRAN) device, a base station (gNB) in an NR system, a radio controller in a Cloud Radio Access Network (CRAN), or a relay station, access point, bridge, router, or network equipment in a future Public Land Mobile Network (PLMN), etc.

[0122] See Figure 3 , Figure 3 This is a flowchart of a first information transmission method provided in an embodiment of the present invention. The first information transmission method is implemented by a first device and includes:

[0123] S11. Receive the inventory message sent by the core network, and send a first paging message containing the inventory message to the second device;

[0124] S12. Receive the first random access message sent by the second device, and send the second random access message to the second device;

[0125] S13. Send a response message carrying the device ID of at least one second device to the core network;

[0126] S14. Receive the command message sent by the core network, and send a second paging message containing the command message to the corresponding second device;

[0127] S15. Receive the command response message sent by the second device.

[0128] For example, the first information transmission method corresponds to the first method described above, in which both the inventory message and the command message are carried by NAS messages. Through NAS messages, the first device can directly interact with the core network.

[0129] See Figure 4 , Figure 4 This is another flowchart of the first information transmission method provided in the embodiments of the present invention. The information interaction between the first device, the second device, the third device and the core network includes steps 1 to 9. Steps 1 to 9 will be used to explain steps S11 to S15 in detail:

[0130] Step 1: The core network sends a first paging message (NAS message) to the first device. The first paging message carries at least an inventory message.

[0131] Step 2: The second device sends an RRC (Radio Resource Control) reconfiguration message to the first device to configure its transmission. Step 2 can be performed before Step 1. The configuration information carried in the RRC reconfiguration message will be described in detail later.

[0132] Step 3: The first device sends the inventory message to the second device. For example, the first device can send the inventory message via broadcast, or the first device can send the inventory message to a designated second device. During the designated sending process, the inventory message carries the device ID of the second device that needs to respond to this inventory message, or the first device is pre-associated with these designated second devices.

[0133] Step 4: After receiving the inventory message, the second device initiates a random access procedure. At this time, the first device receives the first random access message sent by the second device and sends a second random access message to the second device, completing the random access from the second device to the first device. It is worth noting that the random access process between devices can refer to existing technologies, and this invention does not specifically limit it.

[0134] Step 5: After the first device completes random access with the second device, it records the device IDs of the second devices that have established the random access procedure. Then, the first device sends a response message to the core network. The response message contains the device ID of at least one second device that has completed the random access procedure.

[0135] Step 6: After receiving the response message, the core network can determine which second devices responded to the inventory operation, indicating that these second devices can receive command messages. At this point, the core network sends the command message to the first device via a second paging message (NAS message). For example, the command message can be at least one of a read command (reading information recorded by the second device), a write command (writing information to the second device), and a control command (such as shutting down the second device).

[0136] Step 7: After receiving the second paging message, the first device parses the command message and sends the command message to the corresponding second device.

[0137] Step 8: The second device executes the instruction corresponding to the command message and then sends a command response message to the first device. For example, the command response message may be an acknowledgment message, such as when the command message is a write command or control command, in which case the command response message confirms that the second device has responded to the instruction in the command message; or the command response message may be other feedback messages, such as when the command message is a read command, in which case the command response message contains information about the second device that has been read.

[0138] Step 9: After receiving the command response message, the first device sends a NAS message carrying the command response message to the core network, thereby completing the core network's inventory and command operations on the second device.

[0139] In this embodiment of the invention, by carrying the interaction information between the first device and the core network through NAS messages, the first device can directly interact with the core network without the base station. This not only enables the core network to perform inventory and command operations on the A-IoT device, but also improves information transmission efficiency.

[0140] Furthermore, the third device needs to configure information for the first device. The RRC configuration of the third device for the first device can occur before or after the first device receives NAS messages, or it can be done by broadcasting resource information.

[0141] In the first embodiment, the third device configures the first device via RRC, and the method further includes:

[0142] S101, Receive an RRC reconfiguration message sent by a third device; wherein the RRC reconfiguration message carries at least one of the following information: radio bearer, access resources and transmission resources for the first device and the second device, feedback delay information, and failure reporting information.

[0143] ① Radio bearer, used for AIoT information transmission (Radio Bearer, RB), can be a signaling radio bearer (SRB); the corresponding PDCP (Packet Data Convergence Protocol) entity and RLC (Radio Link Control) entity of this radio bearer are used to transmit inventory messages and command messages received by the first device, as well as feedback of inventory messages and command messages;

[0144] ② Access resources and transmission resources between the first device and the second device, wherein the access resources include at least one of the following information: shared time-frequency resources for access, including time-frequency resources for contention and non-contention (shared and dedicated); the number of second devices; dedicated time-frequency resources for access of each second device; identification information of the second devices, such as device ID;

[0145] ③ Feedback latency information, including the maximum latency and / or period for the first device to send uplink / downlink inventory messages and command messages, and / or, including the inventory start time of the first device. The first device needs to transmit information from the second device within this configured time range;

[0146] ④ Failure reporting information includes the failure type of the first device, such as inventory failure, command failure, or reporting failure; such as failure to receive temporary identifier, failure to receive fixed identifier of the second device, command feedback failure, etc., and also carries the failure reason, such as: inventory quantity is less than the inventory message, insufficient resources, short latency, etc.

[0147] Furthermore, the third device can only send an RRC reconfiguration message to the first device if the sending conditions for the RRC reconfiguration message are met. The sending conditions for the RRC reconfiguration message include one of the following:

[0148] 1) The first device supports read and write functions and is in RRC connection state; after the first device reports that its own capabilities include supporting AIoT reader / writer functions, the third device sends an RRC reconfiguration message after the first device is in RRC connection state.

[0149] 2) After receiving the inventory message and / or command message, the first device sends a configuration request message to the third device; and reports the UE assistance information report via RRC message or UE assistance information.

[0150] In the second embodiment, the third device sends resource information to the first device via a broadcast message, and the method further includes:

[0151] S102. Receive a broadcast message sent by a third device; wherein the broadcast message carries access resources for the first device and the second device. The access resources include at least one of the following information: shared time-frequency resources for access, including time-frequency resources for contention-based and non-contention-based (shared and dedicated) access; the number of second devices; dedicated time-frequency resources for access of each second device; and identification information of the second devices, such as device ID.

[0152] It is worth noting that, Figure 4 Steps 3 and 4 shown can be performed in any order with steps 5 and 6. That is, steps 3 and 4 can be performed first, followed by steps 5 and 6, or steps 3 and 4 can be performed after steps 5 and 6. After the third device sends resource information to the first device via broadcast message, the first device can perform steps 3 and 4. After the third device configures the first device via RRC, the first device can perform steps 5 and 6.

[0153] Compared to existing technologies, the first information transmission method disclosed in this invention adds an intermediate device between the base station and the A-IoT device. This intermediate device directly forwards information between the core network and the A-IoT device, enabling the core network to perform inventory and command operations on the geographically distant A-IoT device. Furthermore, by configuring resources for the first device using a third device, the first device can use corresponding resources to forward information between the core network and the second device. Additionally, by configuring feedback latency information, the information transmission efficiency of the first device can be improved.

[0154] See Figure 5 , Figure 5 This is a flowchart of a second information transmission method provided in an embodiment of the present invention. The second information transmission method is implemented by a third device and includes:

[0155] S21. Receive the inventory message sent by the core network, and send a first paging message containing the inventory message to the second device through the first device;

[0156] S22. Receive the first random access message sent by the second device, and send the second random access message to the second device;

[0157] S23. Send a response message carrying the device ID of at least one second device to the core network;

[0158] S24. Receive the command message sent by the core network, and send a second paging message containing the command message to the corresponding second device through the first device;

[0159] S25. Receive the command response message from the second device forwarded by the first device.

[0160] For example, the second information transmission method corresponds to the above-mentioned method 2. In this case, the first device plays a transparent transmission role. The first device transmits the first paging message and the second paging message to the third device. The first device only forwards the message and does not parse the first paging message and the second paging message.

[0161] See Figure 6, Figure 6 This is another flowchart of the second information transmission method provided in the embodiments of the present invention. The information interaction between the first device, the second device, the third device and the core network includes steps 1 to 9. Steps S21 to S25 are described in detail through steps 1 to 9:

[0162] Step 1: The core network sends an inventory message to the third device.

[0163] Step 2: The third device sends an RRC reconfiguration message to the first device to perform transmission configuration on the first device. Step 2 can be performed before Step 1. The configuration information carried in the RRC reconfiguration message will be described in detail later.

[0164] Step 3: The third device sends a first paging message containing the inventory message to the second device. This first paging message needs to be transmitted through the first device before reaching the second device. The third device can send the first paging message to a designated second device. During the designated transmission process, the first paging message carries the device ID of the second device that needs to respond to this inventory message, or the third device is pre-associated with these designated second devices.

[0165] Step 4: After receiving the first paging message, the second device sends a first random access message to the first device to initiate the random access process. The first device then sends a second random access message to the second device, completing the random access from the second device to the third device. It is worth noting that the random access process between devices can refer to existing technologies, and this invention does not specifically limit it.

[0166] Step 5: After the first device completes random access with the third device, the third device records the device IDs of the second devices that have established the random access procedure, and then the third device sends a response message to the core network. The response message contains the device ID of at least one second device that has completed the random access procedure.

[0167] Step 6: After receiving the response message, the core network can determine which second devices responded to the inventory operation, indicating that these second devices can receive command messages. At this point, the core network sends a command message to the third device. For example, the command message can be at least one of a read command (reading information recorded by the second device), a write command (writing information to the second device), and a control command (such as shutting down the second device).

[0168] Step 7: After the third device passes through the first device, it sends a second paging message containing the command message to the second device.

[0169] Step 8: The second device executes the instruction corresponding to the command message and then sends a command response message to the third device. This command response message also needs to be transmitted through the first device. For example, the command response message may be an acknowledgment message, such as when the command message is a write command or control command, in which case the command response message confirms that the second device has responded to the command message instruction; or the command response message may be other feedback messages, such as when the command message is a read command, in which case the command response message contains information about the second device that has been read.

[0170] Step 9: The third device sends the command response message to the core network.

[0171] In this embodiment of the invention, the efficiency of information transmission can be improved by the transparent transmission function of the first device, and the coverage of the third device can be enhanced by forwarding information from the second and third devices through the first device, thus avoiding the situation where the third device cannot find the second device.

[0172] Furthermore, the third device needs to configure information for the first device. The RRC configuration of the third device for the first device can occur before or after the first device receives the inventory message, or it can be done by broadcasting resource information.

[0173] In the first embodiment, the third device configures the first device via RRC, and the method further includes:

[0174] S201.

[0175] ① Wireless bearer, used for AIoT information transmission, can be a signaling wireless bearer (SRB) or a data wireless bearer (DRB); the PDCP entity and RLC entity corresponding to the wireless bearer are used to transmit inventory messages and command messages sent from the third device to the first device, as well as feedback of inventory messages and command messages sent from the first device to the third device.

[0176] ② Access resources and transmission resources between the second device and the third device, wherein the access resources include at least one of the following: shared time-frequency resources for access, including time-frequency resources for contention and non-contention (shared and dedicated); the number of second devices; dedicated time-frequency resources for access of each second device; identification information of the second device, such as device ID;

[0177] ③ Feedback latency information, including the maximum latency and / or period for the first device to send uplink / downlink inventory messages and command messages, and / or, including the inventory start time of the first device. The first device needs to transmit information from the second device within this configured time range;

[0178] ④ Failure reporting information includes the failure type of the first device, such as failure to receive temporary identifier, failure to receive fixed identifier of the second device, or failure to report. The failure type includes failure to receive temporary identifier, failure to receive fixed identifier of the second device, and failure to receive command feedback. It also carries the failure reason, such as failure reason: the inventory quantity is less than the inventory message, insufficient resources, or short latency.

[0179] Furthermore, the third device can only send an RRC reconfiguration message to the first device if the sending conditions for the RRC reconfiguration message are met. The sending conditions for the RRC reconfiguration message include one of the following:

[0180] 1) The first device supports read and write functions and is in RRC connection state; after the first device reports that its own capabilities include supporting AIoT reader / writer functions, the third device sends an RRC reconfiguration message after the first device is in RRC connection state.

[0181] 2) After receiving the inventory message and / or command message, the first device sends a configuration request message to the third device; and reports the UE assistance information report via RRC message or UE assistance information.

[0182] In the second embodiment, the third device sends resource information to the first device via a broadcast message, and the method further includes:

[0183] S202, Send a broadcast message to the first device; wherein the broadcast message carries access resources for the second device and the third device.

[0184] Compared to existing technologies, the second information transmission method disclosed in this invention adds an intermediate device between the base station and the A-IoT device. This intermediate device directly forwards information between the core network and the A-IoT device, enhancing the base station's coverage and preventing situations where the base station cannot locate the A-IoT device. Furthermore, by configuring resources for the first device using a third device, the first device can use corresponding resources to forward information between the core network and the second device. Additionally, by configuring feedback latency information, the information transmission efficiency of the first device can be improved.

[0185] See Figure 7 , Figure 7This is a flowchart of a third information transmission method provided in an embodiment of the present invention. The third information transmission method is implemented by a first device and includes:

[0186] S31. Receive an inventory message sent by a third device, and send a first paging message containing the inventory message to the second device; wherein the inventory message is sent by the core network;

[0187] S32. Receive the first random access message sent by the second device, and send the second random access message to the second device;

[0188] S33. Send a response message carrying the device ID of at least one second device to the third device, so that the third device forwards the response message to the core network;

[0189] S34. Receive the command message sent by the third device, and send a second paging message containing the command message to the corresponding second device; wherein the command message is sent by the core network;

[0190] S35. Receive the command response message sent by the second device.

[0191] For example, the third information transmission method corresponds to the second method described above. In this case, the first device does not transmit the first paging message and the second paging message, but it also needs to parse these two messages itself.

[0192] See Figure 8 , Figure 8 This is another flowchart of the third information transmission method provided in this embodiment of the invention. The information interaction between the first device, the second device, the third device, and the core network includes steps 1 to 13. Steps S31 to S35 are explained in detail through steps 1 to 13:

[0193] Step 1: The core network sends an inventory message to the third device.

[0194] Step 2: The third device sends an RRC reconfiguration message to the first device to perform transmission configuration on the first device. Step 2 can be performed before Step 1. The configuration information carried in the RRC reconfiguration message will be described in detail later.

[0195] Step 3: The third device sends an inventory message to the first device.

[0196] Step 4: The first device sends a first paging message to the second device, the first paging message carrying the inventory message. For example, the first device can send the inventory message via broadcast, or the first device can send the first paging message to a designated second device. During the designated transmission, the first paging message carries the device ID of the second device that needs to respond to this inventory message, or the first device is pre-associated with these designated second devices.

[0197] Step 5: The second device initiates a random access procedure to complete the random access from the second device to the first device. It is worth noting that the random access procedure between devices can refer to existing technologies, and this invention does not specifically limit it.

[0198] Step 6: After the first device completes random access with the second device, it records the device IDs of the second devices that have established the random access procedure. Then, the first device sends a response message to the third device. The response message contains the device ID of at least one second device that has completed the random access procedure.

[0199] Step 7: The third device sends the response message to the core network.

[0200] Step 8: After receiving the response message, the core network can determine which second devices responded to the inventory operation, indicating that these second devices can receive command messages. At this point, the core network sends a command message to the third device. For example, the command message can be at least one of a read command (reading information recorded by the second device), a write command (writing information to the second device), and a control command (such as shutting down the second device).

[0201] Step 9: The third device sends the command message to the first device.

[0202] Step 10: The first device sends a second paging message carrying the command message to the corresponding second device.

[0203] Step 11: The second device executes the instruction corresponding to the command message and then sends a command response message to the first device. For example, the command response message may be an acknowledgment message, such as when the command message is a write command or control command, in which case the command response message confirms that the second device has responded to the instruction of the command message; or the command response message may be other feedback messages, such as when the command message is a read command, in which case the command response message contains information about the second device that has been read.

[0204] Step 12: The first device sends the command response message to the third device.

[0205] Step 13: The third device sends the command response message to the core network.

[0206] In this embodiment of the invention, by forwarding information between the second and third devices through the first device, the coverage of the third device can be enhanced, avoiding situations where the third device cannot find the second device.

[0207] Furthermore, the third device needs to configure information for the first device. The RRC configuration of the third device for the first device can occur before or after the first device receives the inventory message, or it can be done by broadcasting resource information.

[0211] ② Access resources and transmission resources between the first device and the second device, wherein the access resources include at least one of the following information: shared time-frequency resources for access, including time-frequency resources for contention and non-contention (shared and dedicated); the number of second devices; dedicated time-frequency resources for access of each second device; identification information of the second devices, such as device ID;

[0212] ③ Feedback latency information, including the maximum latency and / or period for the first device to send uplink / downlink inventory messages and command messages, and / or, including the inventory start time of the first device. The first device needs to transmit information from the second device within this configured time range;

[0213] ④ Failure reporting information includes the failure type of the first device, such as failure to receive temporary identifier, failure to receive fixed identifier of the second device, or failure to report. The failure type includes failure to receive temporary identifier, failure to receive fixed identifier of the second device, and failure to receive command feedback. It also carries the failure reason, such as failure reason: the inventory quantity is less than the inventory message, insufficient resources, or short latency.

[0214] Furthermore, the third device can only send an RRC reconfiguration message to the first device if the sending conditions for the RRC reconfiguration message are met. The sending conditions for the RRC reconfiguration message include one of the following:

[0216] 2) After receiving the inventory message and / or command message, the first device sends a configuration request message to the third device; and reports the UE assistance information report via RRC message or UE assistance information.

[0217] In the second embodiment, the third device sends resource information to the first device via a broadcast message, and the method further includes:

[0218] S302, Receive a broadcast message sent by a third device; wherein the broadcast message carries access resources for the first device and the second device.
