Description

Technical Field

[0001] The present invention relates to the technical field of passive Internet of Things, and in particular to an instruction processing method, device, medium and program product of a cellular passive Internet of Things. Background Art

[0002] The existing passive IoT RFID includes IoT platforms, read / write devices, and tags. The usual tag identification inventory process is: the platform sends a trigger inventory instruction to the read / write device, the read / write device generates and sends a new tag inventory instruction, the tag replies with its own identification after completing random access, and the read / write device transmits the received data back to the platform. It can be seen that in the tag identification inventory process, the read / write device can generate a new tag inventory instruction according to the platform's instructions, that is, the read / write device can receive and identify all the information of the instructions issued by the platform and perform corresponding processing.

[0003] Cellular passive IoT technology is based on cellular communication networks, combining traditional RFID with 5G cellular networks, and utilizing the high transmission power and coverage of 5G base stations. The core network (CN) in cellular passive IoT can be compared to the platform in traditional RFID, and the radio access network (RAN) in cellular passive IoT can be compared to the reader / writer device in traditional RFID.

[0004] However, the existing 5G NR (5G New Radio, the fifth generation of mobile communication network new wireless access technology) system uses protocol layering technology. The core network and access network operate terminals / tags through different protocols, which makes the protocol-related instructions between the core network and the tag invisible to the access network. Therefore, in the cellular passive Internet of Things system, it is difficult to achieve the instruction conversion method between the platform and the reader and writer in RFID. It is difficult for the access network to generate new tag inventory instructions and high-level data according to the instructions of the core network, and it is difficult to achieve business needs such as tag search and data reporting.

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0061] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0062] It should be noted that Figure 1 This is a schematic diagram of the interaction process between the user terminal, access network and core network in the existing 5G NR system. In the existing 5G NR system, Figure 1 As shown, after the user terminal UE is turned on, it usually completes air interface interaction mechanisms such as system information reception, random access, and RRC connection establishment before establishing contact with the core network CN through registration, authentication and other processes.

[0063] Figure 2 This is a schematic diagram of the interaction protocol between user terminals, access networks, and core networks in the existing 5G NR system. Figure 2As shown in the figure, the 5G NR protocol stipulates that the access network RAN ​​uses the NGAP protocol when interacting with the core network element AMF (access and mobility management function) through the N2 interface, and uses the GTP-U protocol when interacting with the core network element UPF (user plane function) through the N3 interface; the user terminal UE uses the NAS layer protocol when interacting with the core network element AMF through the N11 interface.

[0064] Specifically, the NGAP protocol provides the following two types of services:

[0065] Non-UE related services: related to the N2 interface instance between the base station gNB and the core network element AMF, used to establish the NGAP signaling connection between the base station gNB and the network element AMF, handle some overload conditions, and exchange configuration data between the base station gNB and the network element AMF.

[0066] UE-related services: related to UE, involving signaling processes related to active UEs, such as registration, PDU (protocol data unit) session establishment, deregistration, etc.

[0067] like Figure 2 As shown in the figure, no matter whether NGAP signaling is used to carry non-UE-related services or UE-related services, the NGAP protocol is only valid in the N2 interface between the access network RAN ​​and the core network CN. If the core network element AMF needs to interact with the user terminal UE, the NAS protocol needs to be used, and the NAS protocol-related instructions are invisible to the access network, that is, the access network transparently transmits NAS instructions. At the same time, after the PDU Session is established, when the UE sends uplink data to the cellular network, the user data packet T-PDU (Transport PDU) will be used. After the GTP-U packet header is added to the user data packet on the RAN side, the GTP-U protocol is used to transmit it to the upper layer. The data inside the T-PDU is not visible to the RAN.

[0068] Based on the discussion on the cellular passive IoT topic in 3GPP RAN so far, in terms of protocol stack, such as Figure 3 As shown, Figure 3This is a schematic diagram of the principle of the existing cellular passive IoT protocol stack solution. A candidate protocol stack partitioning scheme is proposed: without distinguishing between the control plane and the user plane, the tag only needs to support the MAC-PHY two-layer air interface protocol stack, and may or may not support the NAS layer protocol. In the above protocol stack, unlike the existing 5G NR NGAP protocol or NAS protocol, the access network needs to see different core network message types and convert them into MAC protocols. However, considering network security, the core network and the tag should support a secure encryption protocol. In addition, since the tag identification generally reflects the information of the item to which the tag is attached, the access network should not have the authority to obtain the user data in the tag.

[0069] It can be seen that the protocols in traditional passive IoT systems are not layered, but in cellular passive IoT systems, the core network and access network operate terminals / tags through different protocols. It is difficult for the access network RAN ​​and the core network CN to achieve the same command conversion method as the platform and the reader / writer in RFID. It is difficult for the access network to generate new tag inventory commands and high-level data according to the instructions of the core network. If the true integration of cellular networks and passive IoT technologies is to be achieved, the conversion solution between air interface commands and core network commands is very necessary and is the basic enabling technology of cellular passive systems. Therefore, it is necessary to design a semi-transparent transmission mechanism between air interface commands and core network commands in the cellular passive IoT system in combination with the business requirements of cellular passive IoT specific tag search / paging, data reporting, etc.

[0070] To solve the above problems, see Figure 4 , is a flow chart of a command processing method for a cellular passive Internet of Things provided by an embodiment of the present invention. An embodiment of the present invention provides a command processing method for a cellular passive Internet of Things, the method being applied to an air interface access device RAN, the method comprising steps S11 to S12:

[0071] S11. When a first instruction is received, obtain a protocol packet header and multiple instruction information in the first instruction; wherein the instruction information includes an instruction type;

[0072] S12. According to the instruction type, the protocol packet header is replaced, and the instruction information is processed using a preset instruction information processing operation to generate a second instruction; wherein the instruction information processing operation is copying, deleting or adding.

[0073] In an embodiment of the present invention, a semi-transparent transmission mechanism between air interface instructions and core network instructions in a cellular passive Internet of Things system is designed and optimized, and the first instruction refers to a core network instruction sent by the core network CN or an air interface instruction sent by a terminal, and correspondingly, the second instruction refers to an air interface instruction sent to the terminal or a core network instruction sent to the core network CN generated after conversion processing by the access network RAN. During the instruction conversion process, the access network RAN ​​obtains the protocol header and each part of the instruction information in the first instruction, determines the corresponding preset instruction information processing operation according to the instruction type of the first instruction, replaces the protocol header of the first instruction, and processes each part of the instruction information through the instruction information processing operation, thereby converting to obtain a new second instruction.

[0074] Specifically, when the core network instructions of the core network CN need to be identified and processed by the access network RAN ​​before being forwarded to the terminal, the core network CN opens the identification authority of some instruction information to the access network RAN, allowing the access network RAN ​​to perform corresponding processing operations on the instruction information and generate air interface instructions sent to the terminal; when the air interface message of the terminal needs the access network RAN ​​to assist the terminal in generating high-level messages and forwarding them to the core network, the access network RAN ​​is also allowed to identify some instruction information and perform corresponding processing operations to generate core network instructions sent to the core network CN.

[0075] It should be noted that the terminal is an extremely low power consumption terminal. An extremely low power consumption terminal refers to a new type of IoT terminal that does not rely on traditional battery power and can use backscatter communication technology for communication. The extremely low power consumption terminal includes but is not limited to at least one of the following: a new type of passive IoT tag, an environmental IoT terminal, etc.

[0076] It should be noted that the air interface protocol refers to the protocol used by air interface access devices such as base stations and gateways to inventory / read and write ultra-low power terminals, including protocols such as 5G NR PHY, 5G NR MAC, or protocols with similar functions. The core network protocol refers to the protocol used by air interface access devices such as base stations and gateways to establish connections and transmit data with network elements, including protocols such as 5GNR L1, 5G NR L2, 5G NR IP, 5G NR SCTP, 5G NR NG-AP, or protocols with similar functions.

[0077] By adopting the technical means of the embodiment of the present invention, a conversion means between core network instructions and air interface instructions in a cellular passive Internet of Things system is proposed, and each instruction information in the instruction is obtained through the access network, and the protocol packet header of the instruction is replaced according to the instruction type, and the corresponding instruction information processing operation is determined according to the instruction type, so as to perform corresponding processing operations such as copying, deleting or adding on each instruction information to generate a new instruction. It clarifies some data visible to the access network during the interaction between the core network and the terminal, and sets corresponding instruction processing operations such as copying, deleting or adding on the instruction information according to the instruction type, clearly divides the control authority of the core network and the access network over the terminal, effectively combines the control capability of the core network over the terminal with the air interface resource scheduling and division capability of the access network, completes the terminal control through a single instruction, and simplifies the protocol stack and communication interaction logic. The embodiment of the present invention provides a conversion process between the air interface instruction and the core network instruction of the cellular passive Internet of Things system, fills the blank of the semi-transparent transmission mechanism between the air interface instruction and the core network instruction in the cellular passive Internet of Things system, effectively improves the flexibility of the cellular passive Internet of Things system, and better realizes the combination of the passive Internet of Things and the cellular network.

[0078] As a preferred implementation manner, the embodiment of the present invention is further implemented on the basis of the above embodiment, and the process of converting the first instruction to generate the second instruction by the access network RAN ​​is further optimized.

[0079] In a first implementation manner, the first instruction is a core network instruction sent by a core network element, and the second instruction is an air interface instruction sent to a terminal.

[0080] Then step S12, that is, replacing the protocol packet header according to the instruction type, and processing the instruction information using a preset instruction information processing operation to generate a second instruction, includes steps S121 and S122:

[0081] S121. Replace the protocol packet header in the core network instruction with an air interface protocol packet header;

[0082] S122. According to the instruction type of the core network instruction, use a preset instruction information processing operation to process the instruction information in the core network instruction to generate the air interface instruction.

[0083] An embodiment of the present invention proposes a method for converting a core network instruction to an air interface instruction (C2R). When an access network RAN ​​receives a core network instruction sent by a core network CN, a protocol packet header and multiple instruction information in the core network instruction are obtained, where the instruction information includes an instruction type, etc. According to the instruction type, the protocol packet header is replaced with an air interface protocol packet header. At the same time, according to the pre-set instruction information processing operation for each instruction information corresponding to the instruction type, each instruction information in the core network instruction is processed, including operations such as copying, deleting or adding instruction information, so as to refer to each instruction information of the core network instruction, generate each instruction information of the air interface instruction, and obtain the air interface instruction.

[0084] More preferably, based on the above embodiment, the embodiment of the present invention proposes three instruction conversion methods for core network instructions to air interface instructions. Step S122, that is, according to the instruction type of the core network instruction, the instruction information in the core network instruction is processed using a preset instruction information processing operation to generate the air interface instruction, including:

[0085] When the instruction type of the core network instruction is the first instruction type, each instruction information in the core network instruction is copied to generate the air interface instruction.

[0086] When the instruction type of the core network instruction is the second instruction type, the first instruction information in the core network instruction is copied, and the second instruction information in the core network instruction is deleted to generate the air interface instruction.

[0087] When the instruction type of the core network instruction is the third instruction type, the first instruction information in the core network instruction is copied, the second instruction information in the core network instruction is deleted, and the third instruction information is added to generate the air interface instruction.

[0088] Specifically, the first instruction conversion method (C2R conversion method 1) is applicable to the scenario where the high-level instructions of the core network CN need to be forwarded by the access network RAN ​​to the terminal, and the access network RAN ​​does not need to add any new instruction information. In this conversion method, after the access network RAN ​​receives the core network instructions sent by the core network CN, it will identify each instruction information, replace the air interface protocol packet header according to the instruction type, and copy the remaining other instruction information to generate an air interface instruction. In this conversion method, the access network RAN ​​has a low degree of autonomy in generating instructions.

[0089] The second instruction conversion method (C2R conversion method 2) is applicable to the scenario where the high-level instructions of the core network CN need to be forwarded by the access network RAN ​​to the terminal, and the access network RAN ​​only has the operation of deleting instruction information, and does not need to add any instruction information. In this conversion method, after the access network RAN ​​receives the core network instruction sent by the core network CN, it will identify part of the instruction information, replace the air interface protocol packet header according to the instruction type, delete part of the instruction information, copy part of the instruction information, refer to the various instruction information of the core network instruction, and generate various instruction information of the air interface instruction to generate the air interface instruction. In this conversion method, the access network RAN ​​has a medium degree of autonomy in generating instructions.

[0090] The third instruction conversion method (C2R conversion method 3) is applicable to scenarios where high-level instructions of the core network CN need to be forwarded by the access network RAN ​​to the terminal, and the access network RAN ​​has operations of deleting instruction information and adding new instruction information. In this conversion method, after the access network RAN ​​receives the core network instruction sent by the core network CN, it will identify part of the instruction information, replace the air interface protocol packet header according to the instruction type, delete part of the instruction information, copy part of the instruction information, and at the same time, add part of the air interface information to generate the air interface instruction. In this method, the RAN has a high degree of autonomy in generating instructions.

[0091] It should be noted that the operations of copying and deleting each part of the instruction information in the core network instruction and adding new instruction information are all predetermined according to the instruction type of the core network instruction and are not specifically limited here.

[0092] In a second implementation manner, the first instruction is an air interface instruction sent by the terminal, and the second instruction is a core network instruction sent to a core network element.

[0093] Then step S12, that is, replacing the protocol packet header according to the instruction type, and processing the instruction information using a preset instruction information processing operation to generate a second instruction, includes steps S123 and S124:

[0094] S123, replacing the protocol packet header in the air interface instruction with a core network protocol packet header;

[0095] S124. According to the instruction type of the air interface instruction, use a preset instruction information processing operation to process the instruction information in the air interface instruction to generate the core network instruction.

[0096] The embodiment of the present invention proposes a method for converting air interface instructions to core network instructions (R2C). When the access network RAN ​​receives the air interface instruction sent by the terminal, the protocol packet header and multiple instruction information in the air interface instruction are obtained, and the instruction information includes the instruction type, etc. According to the instruction type, the protocol packet header is replaced with the core network protocol packet header. At the same time, according to the pre-set instruction information processing operation for each instruction information corresponding to the instruction type, each instruction information in the core network instruction is processed, including operations such as copying, deleting or adding instruction information, so as to refer to each instruction information of the air interface instruction, generate each instruction information of the core network instruction, and obtain the core network instruction.

[0097] More preferably, based on the above embodiments, the embodiments of the present invention further optimize the method for converting air interface instructions to core network instructions. Step S124, that is, according to the instruction type of the air interface instruction, a preset instruction information processing operation is used to process the instruction information in the air interface instruction to generate the core network instruction, including: copying the fourth instruction information in the air interface instruction, deleting the fifth instruction information in the air interface instruction, to generate the core network instruction.

[0098] Specifically, the method for converting air interface commands to core network commands, that is, the fourth command conversion method (R2C conversion method), is applicable to the scenario where the air interface message of the terminal needs to be assisted by the access network RAN ​​to generate a high-level message to the terminal and forwarded to the core network CN. Under this conversion method, after receiving the air interface message fed back by the terminal, the access network RAN ​​will identify each part of the command information, replace the core network protocol packet header, delete part of the command information, and copy part of the command information to generate the core network command.

[0099] It should be noted that the operations of copying and deleting each part of the instruction information in the air interface instruction and adding new instruction information are all predetermined according to the instruction type of the air interface instruction, and are not specifically limited here.

[0100] By adopting the technical means of the embodiment of the present invention, a plurality of conversion methods for converting core network instructions to air interface instructions in a cellular passive Internet of Things system, and a method for converting air interface instructions to core network instructions are proposed. In the method for converting core network instructions to air interface instructions, the core network opens the recognition authority of some instructions to the access network, and at the same time, distinguishes whether the access network needs to delete or add instruction information based on the core network instructions, so as to design instruction conversion schemes with different transparency. In the method for converting air interface instructions to core network instructions, the access network only recognizes part of the instruction information, and copies the relevant instruction information to convert it into a high-level message. In the instruction conversion method of the embodiment of the present invention, it is clarified that part of the data interacted between the core network and the terminal can be encrypted for transmission, that is, part of the content that is invisible to the access network, and the control authority of the core network and the access network over the terminal is clearly divided. In combination with actual business needs, a means for the access network to copy, delete or add part of the instruction information is provided, which can effectively combine the control capability of the core network over the terminal with the air interface resource scheduling and division capability of the access network, complete terminal control through a single instruction, and simplify the protocol stack and communication interaction logic. The embodiment of the present invention provides a conversion process between air interface instructions and core network instructions of a cellular passive Internet of Things system, which fills the gap of the semi-transparent transmission mechanism between air interface instructions and core network instructions in the cellular passive Internet of Things system, effectively improves the flexibility of the cellular passive Internet of Things system, and better realizes the combination of the passive Internet of Things and the cellular network.

[0101] As a preferred implementation, an embodiment of the present invention also provides a specific implementation scenario in which the above-mentioned instruction conversion method is applied in a cellular passive Internet of Things system to convert between core network instructions and air interface instructions. An embodiment of the present invention provides an instruction processing method for a cellular passive Internet of Things, which is applied to an air interface access device.

[0102] In the first implementation scenario, the method includes steps S21 to S24:

[0103] S21. When a core network paging instruction sent by a core network network element is received, the core network paging instruction is processed by the second instruction conversion method (C2R conversion method 2) in the above embodiment to generate an air interface paging instruction; wherein the core network paging instruction is used to request to establish a connection between the core network network element or the air interface access device and the terminal; the first instruction information in the core network paging instruction includes an instruction type, a terminal unique identification mask and a terminal session state, and the second instruction information includes the number of terminals and the terminal type;

[0104] S22, sending the air interface paging instruction to the terminal, combining other core network element instructions or air interface instructions to complete random access of the terminal;

[0105] S23. When receiving the air interface feedback instruction sent by the terminal, process the air interface feedback instruction using the fourth instruction conversion method (R2C conversion method) in the above embodiment to generate a core network feedback instruction; wherein the air interface feedback instruction includes the terminal fixed unique identifier of the terminal; the fourth instruction information in the air interface feedback instruction includes the terminal fixed unique identifier, and the fifth instruction information includes an instruction type;

[0106] S24. Send the core network feedback instruction to the core network element.

[0107] Furthermore, the method further comprises steps S25 to S28:

[0108] S25. When receiving a core network data read instruction sent by the core network network element, the core network data read instruction is processed by the first instruction conversion method (C2R conversion method 1) in the above embodiment to generate an air interface data read instruction; wherein the core network data read instruction is used to request to read the terminal data of the terminal; the first instruction information of the core network data read instruction includes an instruction type and a terminal data reporting method;

[0109] S26, sending the air interface data reading instruction to the terminal;

[0110] S27. When receiving the air interface terminal data instruction sent by the terminal, the air interface terminal data instruction is processed by the fourth instruction conversion method (R2C conversion method) in the above embodiment to generate a core network terminal data instruction; the fourth instruction information in the air interface terminal data instruction includes terminal data information, and the fifth instruction information includes an instruction type;

[0111] S28. Send the core network terminal data instruction to the core network element.

[0112] Specifically, the first implementation scenario is the "inventory + command control" scenario, that is, the read / write device of the cellular passive IoT system reads and reports the terminal's identification information, and sends control commands such as "read data" and "write data" to the terminal to complete the operation of the terminal's memory area. The communication process of the "inventory + command control" scenario involves the conversion method from core network commands to air interface commands, and the conversion method from air interface commands to core network commands.

[0113] It should be noted that the terminal data may include a unique terminal identity, user-defined memory area data of the terminal, data collected by terminal sensors, and the like.

[0114] Take the terminal as a passive IoT tag (referred to as tag) as an example, see Figure 5, is a flow chart of the instruction processing method in the first implementation scenario of the embodiment of the present invention. In the inventory stage, the reading and writing device needs to read and report the identification information of the tag. The specific process is as follows:

[0115] Step 1. The network elements of the core network CN, such as the AMF network element and the label management network element, send a core network paging instruction (NG_Select) to the access network RAN. The instruction header (NG_Header), instruction type, number of labels, and user / label type in the core network paging instruction are visible to the access network, and the information related to the label grouping, such as the label unique identification mask and the label session status, is not visible to the access layer (the NAS layer security algorithm may be used to encrypt these fields).

[0116] Steps 2 to 4: After the access network RAN ​​receives the core network paging command (NG_Select), refer to Figure 8 , is a schematic diagram of the principle of the second instruction conversion method in the embodiment of the present invention. The access network RAN ​​uses the above-mentioned C2R forwarding method 2 to identify the instruction information necessary for generating an air interface paging instruction, including instruction type, label quantity, label type, etc., and replaces the NGAP layer protocol packet header to the MAC layer protocol packet header according to the instruction, and deletes part of the instruction information visible to the access network RAN, such as the label quantity and label type; copies the instruction information related to the label grouping, such as the label unique identification mask, label session status, etc., to generate an air interface paging instruction (MAC_Select). At the same time, refer to the label quantity and other information in the core network paging instruction (NG_Select) to generate an air interface inventory instruction (MAC_Query).

[0117] Steps 5-6: The tag sends an air interface temporary identifier to the access network RAN ​​to compete for access resources. The access network RAN ​​sends an air interface temporary identifier confirmation to the tag that successfully competes, completing random access.

[0118] Steps 7 to 9: The tag sends a fixed unique identifier, i.e., an air interface feedback instruction, to the access network RAN ​​(the identifier is used to uniquely identify the tag and / or the item / person attached to the tag). After the access network RAN ​​receives the air interface feedback instruction (MAC_tag fixed unique identifier) ​​of the tag, refer to Fig.10 , is a schematic diagram of the principle of the fourth instruction conversion method in an embodiment of the present invention, using the above-mentioned R2C forwarding method, identifying the instruction type (also called message type) and other instruction information of the air interface feedback instruction, replacing the MAC layer protocol packet header to the NGAP layer protocol packet header, optionally deleting the instruction information of the message type, and copying the remaining instruction information, such as the label fixed unique identifier, to generate a core network feedback instruction (NG_label fixed unique identifier) ​​and send it to the core network network element.

[0119] Furthermore, if Figure 5 As shown, in the instruction control stage, a read / write device is required to perform operations such as reading / writing data in the tag memory area. Taking reading data in the tag memory area as an example, in this embodiment, two data reading methods (method A and method B) and corresponding instruction conversion methods are given, and the specific process is as follows:

[0120] Method A:

[0121] Step 10a: The core network element directly uses the high-level data read instruction (NAS_Read) to interact with the tag, and the RAN completely transparently transmits the instruction. The instruction carries parameters such as the tag memory area address and the memory data size to be reported to indicate the data reporting method.

[0122] Step 11a: The tag uses the NAS layer message to reply the data information (NAS_ReadReply) according to the parameters configured by the NAS_Read instruction, and the RAN completely transparently transmits the message to the core network.

[0123] Method B:

[0124] Step 10b, the core network element sends a core network data read instruction (NG_Read) to the access network RAN. The instruction header (NG_Header) and instruction type in the instruction are visible to the access network, and the tag data reporting method, such as the tag memory area address, the size of the memory data to be reported, and other parameters are not visible to the access layer (the NAS layer security algorithm may be used to encrypt these fields).

[0125] Steps 11b to 12b: After the access network RAN ​​receives the core network data read instruction, see Figure 7 , is a schematic diagram of the principle of the first instruction conversion method in an embodiment of the present invention. The access network RAN ​​uses the above-mentioned C2R forwarding method 1 to identify the instruction type, replace the NGAP layer protocol header to the MAC layer protocol header according to the instruction type, copy the instruction type and the content related to the tag data reporting method to generate an air interface data read instruction (MAC_Read), and send it to the passive tag.

[0126] Steps 13b to 15b, the tag sends an air interface tag data command (MAC_ReadReply) to the access network RAN. The command header (NG_Header) and message type in the message are visible to the access network, and information related to the tag storage area data, such as sensor information collected by the tag and user-defined information written, is not visible to the access layer (the NAS layer security algorithm may be used to encrypt these fields). After the access network RAN ​​receives the tag feedback, if Fig.10As shown, the above-mentioned R2C forwarding method is used to identify the message type instruction information in the air interface label data instruction, replace the MAC layer protocol header to the NGAP layer protocol header, optionally delete the message type instruction information, and copy the information related to the label storage area data, such as label data information (sensor information collected by the label, user-defined information written, etc.) to generate a core network label data instruction (NG_ReadReply) and send it to the core network network element.

[0127] As a preferred implementation, in the second implementation scenario, the method further includes steps S31 to S34:

[0128] S31. When receiving a core network data reporting instruction sent by the core network network element, the core network data reporting instruction is processed by the third instruction conversion method (C2R conversion method 3) in the above embodiment to generate an air interface data reporting instruction; wherein the core network data reporting instruction is used to request to read the terminal data of the terminal, the first instruction information in the core network data reporting instruction includes the instruction type, the terminal unique identification mask and the terminal data reporting mode, the second instruction information includes the terminal quantity and the terminal type, and the third instruction information includes the terminal signal generation mode;

[0129] S32, sending the air interface data reporting instruction to the terminal;

[0130] S33. When receiving an air interface terminal data instruction sent by the terminal, the air interface terminal data instruction is processed by the fourth instruction conversion method (R2C conversion method) in the above embodiment to generate a core network terminal data instruction; the fourth instruction information in the air interface terminal data instruction includes terminal data information, and the fifth instruction information includes an instruction type;

[0131] S34. Send the core network terminal data instruction to the core network element.

[0132] Specifically, the second implementation scenario is the "command control only" scenario, which only requires the cellular passive IoT reader / writer to send control commands such as "read data" and "write data" to the terminal to complete the operation of the terminal memory area. The command control process does not need to be bound to the inventory process, and there is no order relationship between the two processes. Similar to the above "inventory + command control" scenario, the communication process of the "command control only" scenario also involves the command conversion method from the core network to the air interface, and the conversion method from the air interface to the core network command, but the specific conversion method is inconsistent with the above.

[0133] Still taking the terminal as a passive IoT tag (referred to as tag) as an example, see Figure 6, is a flow chart of the instruction processing method in the second implementation scenario in the embodiment of the present invention, and the specific process is as follows:

[0134] Step 1. The core network element sends a core network data reporting instruction (NG_ReportDeviceData) to the access network RAN. The instruction header (NG_Header), instruction type, number of tags, and user / tag type in the instruction are visible to the access network. The tag identifier and tag data reporting method, such as the tag memory area address and the size of the memory data to be reported, are not visible to the access layer (the NAS layer security algorithm may be used to encrypt these fields).

[0135] Steps 2-3: After the access network RAN ​​receives the core network data reporting instruction, refer to Fig. 9 , is a schematic diagram of the principle of the third instruction conversion method in an embodiment of the present invention. The access network RAN ​​uses the above-mentioned C2R forwarding method 3 to identify the instruction type, and replaces the NGAP layer protocol packet header to the MAC layer protocol packet header according to the instruction type, and copies the instruction type and the content related to the label identification and data reporting method, such as the label memory area address, the memory data size to be reported and other parameters. At the same time, it adds the indication information related to the label uplink signal generation method, such as the uplink coding method, the number of uplink time slots that can be accessed competitively, etc., to generate an air interface data reporting instruction (MAC_ReportDeviceData).

[0136] Steps 4 to 6: The tag sends an air interface tag data command (MAC_DataReply) to the RAN. After the access network RAN ​​receives the tag feedback, Fig.10 As shown, using the above-mentioned R2C forwarding method, the message type instruction information in the air interface label data instruction is identified, the MAC layer protocol header is replaced with the NGAP layer protocol header, the message type instruction information is optionally deleted, and the remaining instruction information is copied to generate a core network label data instruction (NG_DataReply), and sent to the core network network element.

[0137] It should be noted that the embodiment of the present invention also provides a third implementation scenario, see Fig.11 , is a flow chart of the instruction processing method under the third implementation scenario in the embodiment of the present invention. In the third implementation scenario, the access network RAN ​​can completely transparently transmit the core network message. The instruction information sent by the core network to the label and the identification and data information fed back by the label are completely carried by the NAS layer message, and there is no need to use the instruction conversion method.

[0138] Step 1: The core network element sends a command (NG_ReportDeviceID) to the access network RAN ​​to report the configuration parameters related to the tag ID. The command carries information such as the number of tags. The complete command is visible to the access network. After receiving the core network command, the access network RAN ​​determines the parameter configuration in the subsequent inventory command (MAC_Query).

[0139] Step 2: The core network element directly uses the high-level data read instruction (NAS_Select) to interact with the label, and the access network RAN ​​completely transparently transmits the instruction, which carries information related to the label grouping, such as the label unique identification mask, label session status, etc.

[0140] Step 3: The access network RAN ​​refers to the parameter configuration in the NG_ReportDeviceID command and generates an air interface inventory command (MAC_Query).

[0141] Steps 4-5: The tag sends an air interface temporary identifier to the access network RAN ​​to compete for access resources. The access network RAN ​​sends an air interface temporary identifier confirmation to the tag that successfully competes, completing random access.

[0142] Step 6: The tag uses a NAS layer message to send a fixed unique identifier (NAS_tag fixed unique identifier, which is used to uniquely identify the tag and / or the item / person to which the tag is attached) to the core network, and the access network RAN ​​fully transparently transmits the message.

[0143] Step 7: The core network uses a high-level data read instruction (NAS_Read) to interact with the tag, and the access network RAN ​​completely transparently transmits the instruction. The instruction carries parameters such as the tag memory area address and the size of the memory data to be reported to indicate the data reporting method.

[0144] Step 8: The tag uses the NAS layer message to reply the data information (NAS_ReadReply) according to the parameters configured by the NAS_Read instruction, and the access network RAN ​​completely transparently transmits the message to the core network.

[0145] It should be noted that, in the above process, unless otherwise specified, the NG_XX instruction is an NGAP layer instruction, or an instruction with similar functions to the 5G NRNAGP layer; the NAS_XX instruction is an NAS layer instruction, or an instruction with similar functions to the 5G NR NAS layer; the MAC_XX instruction is a MAC layer instruction, or an instruction with similar functions to the 5G NR MAC layer.

[0146] By adopting the technical means of the embodiments of the present invention, a conversion process between air interface commands and core network commands of a cellular passive Internet of Things system is provided, which fills the gap of the semi-transparent transmission mechanism between air interface commands and core network commands in the cellular passive Internet of Things system. At the same time, a variety of specific implementation scenarios suitable for conversion between air interface commands and core network commands in the cellular passive Internet of Things system are proposed, including "inventory + command control" scenario, "command control only" scenario, etc., which can effectively meet the specific terminal search / paging, data reporting and other business requirements in the cellular passive Internet of Things system, and effectively improve the flexibility of the cellular passive Internet of Things system.
