[0047] To make the objectives, technical solutions and advantages of the present application clearer and more understandable, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other

[0048] With the development of the future Internet of Things (IoT), it may be necessary to deploy a network of millions or even billions of small, low-power IoT devices to meet the requirements of various applications. However, it is unrealistic for all IoT devices to rely on batteries that need to be manually replaced or charged, which is not only costly but may also cause environmental and safety problems. What is actually needed in practical applications are small, simple battery-free devices, or devices with limited energy storage that do not require manual charging, and these devices usually output power between 1 microwatt and several hundred microwatts

[0049] Existing radio frequency identification (RFID) devices, although having low power consumption, have extremely limited communication distances, resulting in high costs for deploying the IoT and are not suitable for the development of the future IoT. In addition, due to the lack of interference management solutions, the severe interference and capacity problems between RFID readers are particularly prominent, especially in the case of dense deployments. For RFID, it is difficult to support large-scale IoT networks with seamless coverage. Therefore, ambient power-enabled IoT (AIoT) has emerged

[0050] In the work plan of Release 19 of 5G published by 3GPP, the following two types of AIoT network deployments will be supported (note that in actual deployments, there may be a hybrid deployment of the two types) Figure 1aA schematic diagram of network deployment is provided. An AIoT device can directly send its AIoT information / data (i.e., send an AIoT message) to a base station and directly receive AIoT information / data from the base station (i.e., receive an AIoT message). Here, a certain base station can be defined as a Radio Access Network AIoT Reader (RAN AIoTreader).

[0051] Figure 1b Another schematic diagram of network deployment is provided as follows Figure 1b as shown. In an AIoT system, considering the limited coverage areas of base stations and AIoT devices in a 5G AIoT network (e.g., limited transmission and / or reception ranges), one or more intermediate nodes between the base station and the AIoT device may be used to expand the coverage area. Generally, a User Equipment (UE) or a relay node can be used as an intermediate node. An AIoT device can send its AIoT information / data (i.e., send an AIoT message) to a base station through a certain UE with AIoT capabilities and receive AIoT information / data from the base station through a certain UE with AIoT capabilities (i.e., receive an AIoT message). Here, a base station and one or more UEs within the coverage area of the base station can be defined together as a Radio Access Network AIoT Reader.

[0052] The Radio Access Network AIoT Reader can receive operation instructions for AIoT from a 5G core network. The operation instructions can include at least one of the following: Inventory, or Command, the meanings of which in this document are as follows:

[0053] Inventory: A process used to discover and obtain the identifiers of a single or a group of AIoT devices, and it can also require the AIoT devices to report additional data for inventory (such as device production date, device type, location where the device is located, etc.);

[0054] Command: A process of sending an operation request (e.g., read, write) to an AIoT device.

[0055] In some embodiments, the first communication node can be a Radio Access Network AIoT Reader, e.g., a base station; the second communication node can be an AIoT device. The third communication node can be a Core Network (CN).

[0056] Figure 2 A flowchart of a communication method provided for an embodiment is as Figure 2 shown. The communication method described in the embodiments of the present application is applied to the first communication node. The method includes S110:

[0057] S110. Send a first request message to a second communication node. The first request message is used to instruct the second communication node to execute a corresponding command. The first request message includes at least one device identifier and invisible data corresponding to each device identifier. The invisible data is data invisible to the first communication node.

[0058] Among them, the first request message can be understood as a kind of indication message, instructing the second communication node to execute a corresponding command. For example, execute an inventory operation, execute a command operation, etc. The device identifier can be understood as information that uniquely identifies a device. It can be a number, a letter, a special character, etc., or it can be composed of one or more characters such as numbers, letters, and special characters. In this application, the device identifier generally refers to device identification information and can be used to identify the device. Invisible data refers to data that is processed through encryption or other means so that its content cannot be directly obtained. Any privacy data that needs to be kept confidential can be processed as invisible data for transmission.

[0059] The first communication node sends the first request message to one or more second communication nodes. When the first communication node sends the first request message to the second communication node, it can send the first request message to one or more second communication nodes within the coverage area of the first communication node. The first communication node can send the first request message when certain conditions are met or when a trigger is received, etc. The first request message can be information received by the first communication node from other devices, that is, after the first communication node obtains the first request message, it forwards the first request message to the second communication node. It can also be that after the first communication node receives information from other devices, it processes the received information such as recombination to form the first request message. The first request message includes at least one device identifier and invisible data corresponding to each device identifier. The device identifier is visible data; the first request message is used to instruct the second communication node to execute a corresponding command. The device identifier in the first request message can be used to indicate whether the second communication node needs to execute the corresponding command. The invisible data can be information required during the execution of the command or any data that needs to be transmitted. The invisible data is data invisible to the first communication node, that is, the first communication node cannot parse the specific content of this part of the data, realizing the protection of privacy data and avoiding the leakage of privacy data.

[0060] In the communication method provided by the embodiments of the present application, the first communication node instructs the second communication node to execute corresponding commands by sending first request information to the second communication node. The first request information includes at least one device identifier and invisible data corresponding to each device identifier. The invisible data is data invisible to the first communication node. Thus, the protection of privacy data during the device operation process is achieved, and the leakage of privacy data is avoided. The first communication node can instruct the second communication node under the condition of data privacy protection, and the second communication node can normally execute the corresponding commands without the problem of privacy data leakage.

[0061] In some embodiments, the invisible data includes command information of the device.

[0062] Among them, the command information of the device can be used to instruct the specific command to be executed by the second communication node, and the command information can form invisible data through encryption or other means.

[0063] In some embodiments, the command information includes at least one of the following: command type, data corresponding to the command;

[0064] Among them, the command type can be operations such as reading, querying, writing, etc.; the data corresponding to the command can be the type of information to be read, the item to be queried, or the data to be written, etc.

[0065] In some embodiments, if the command type does not contain sensitive data, the command type can be placed in the visible data of the first communication node.

[0066] In some embodiments, the method further includes:

[0067] Receiving first feedback information from the second communication node in response to the first request information;

[0068] Among them, the first feedback information includes at least one of the following:

[0069] Device identifier of the second communication node;

[0070] Invisible data of the second communication node. The invisible data of the second communication node is data invisible to the first communication node, and the invisible data of the second communication node includes command operation results.

[0071] Among them, the first feedback information can be understood as information for feedback on the first request information; after receiving the first request information, the second communication node executes corresponding operations according to the first request information and generates the first feedback information to feedback to the first communication node.

[0072] The first communication node receives first feedback information from one or more second communication nodes in response to the first request information.

[0073] The first feedback information includes at least one of the device identifier of the second communication node and the invisible data. That is, when the second communication node generates the first feedback information, it carries one of the device identifier of its own device and the invisible data in the first feedback information. The invisible data is data invisible to the first communication node, that is, invisible to the first communication node, to avoid data leakage, and the device identifier is visible data. The invisible data of the second communication node includes command operation results. For example, the type, location, etc. of the device.

[0074] In some embodiments, before sending the first request information to the second communication node, the method further includes:

[0075] Receiving a second request information sent by a third communication node, where the second request information is used to instruct the first communication node to execute a corresponding command for the corresponding second communication node;

[0076] Wherein, the second request information includes: the device identifiers of at least one second communication node and the invisible data corresponding to each device identifier. The invisible data is data invisible to the first communication node, and the invisible data includes the command information of the device.

[0077] Wherein, the second request information can be understood as a kind of indication information, used to request the first communication node to execute a corresponding command for the corresponding second communication node. For example, perform an inventory operation, execute a command operation, etc.

[0078] Before sending the first request information to the second communication node, the first communication node receives the second request information sent by the third communication node, and executes the corresponding command for the corresponding second communication node according to the indication of the second request information. The second request information includes: the device identifiers of at least one second communication node and the invisible data corresponding to each device identifier. The invisible data is data invisible to the first communication node, and the invisible data includes the command information of the device. After receiving the second request information, the first communication node determines the second communication node that needs to execute the corresponding command according to the device identifier carried in the second request information.

[0079] The third communication node can actively generate or generate the second request information under certain conditions, and carry it in the second request information, and instruct the first communication node to execute the corresponding command for the corresponding second communication node through the second request information. The third communication node indicates the specific second communication node that executes the command by carrying the device identifier in the second request information. The third communication node can encrypt the privacy data that needs to be kept confidential and carry it as invisible data in the second request information; the invisible data includes the command information of the device. The third communication node indicates the information such as the command executed by the second communication node by carrying the invisible data in the second request information, and the invisible data is invisible to the first communication node.

[0080] After receiving the second request information, the first communication node may parse the second request information to determine the device identifier and the invisible data, and generate the first request information based on the device identifier and the invisible data; or directly forward the second request information as the first request information. When sending the first request information, the first communication node may send the first request information to the corresponding second communication node according to the device identifier, or broadcast the first request information to all second communication nodes within the coverage area, and so on.

[0081] In some embodiments, the method further includes:

[0082] Feedback the second feedback information for the second request information to the third communication node according to the received first feedback information;

[0083] Wherein, the second feedback information includes at least one of the following:

[0084] The device identifier of the second communication node;

[0085] The invisible data of the second communication node, the invisible data of the second communication node is data invisible to the first communication node, and the invisible data of the second communication node is at least one of the command operation result and the inventory result data.

[0086] Wherein, the second feedback information can be understood as the information for feedback on the execution result of the second request information.

[0087] After receiving the first feedback information, the first communication node determines the execution results of each second communication node, generates the second feedback information according to the execution results of the second communication node, and sends the second feedback information to the third communication node, feeding back the second feedback information of the second request information to the third communication node. The second feedback information includes at least one of the device identifier of the second communication node and the invisible data. After receiving the second feedback information, the third communication node may determine the second communication node for feedback according to the device identifier, and may determine the execution result of the feedback according to the corresponding invisible data. The invisible data of the second communication node is data invisible to the first communication node. The third communication node may perform operations such as decryption on the invisible data to make the invisible data visible to the third communication node. Wherein, the invisible data of the second communication node may be at least one of the command operation result and the inventory result data, and the results of the command operation and the inventory are fed back.

[0088] In some embodiments, the invisible data is encapsulated in at least one protocol data unit or byte string.

[0089] In some embodiments, the protocol data unit is a non-access stratum data unit or an environmental Internet of Things device application layer protocol data unit.

[0090] In some embodiments, before the first communication node sends the first request message to the second communication node, the first communication node may also send an inventory message to the second communication node to perform an inventory on the second communication node. After receiving the feedback message from the second communication node, the first communication node saves the device identifier of the second communication node. At this time, it can be considered that the first communication node discovers this second communication node, or the first communication node establishes an association relationship with this second communication node. After establishing the association relationship with the second communication node, the first communication node may send a first request message to the second communication node, requesting the second communication node to execute a corresponding command.

[0091] In the communication method provided by the embodiments of the present application, the first communication node receives the second request message sent by the third communication node, and sends a first request message to the second communication node according to the indication of the second request message, instructing the second communication node to execute a corresponding command. The second request message includes at least one device identifier of the second communication node and the invisible data corresponding to each device identifier. The invisible data is data invisible to the first communication node. The first request message includes at least one device identifier and the invisible data corresponding to each device identifier. The invisible data is data invisible to the first communication node. The first communication device receives the first feedback message fed back by the second communication node, and sends a second feedback message to the third communication node according to the first feedback message. The second feedback message includes at least one of the device identifier of the second communication node and the invisible data. The invisible data of the second communication node is data invisible to the first communication node. The invisible data of the second communication node is at least one of the command operation result and the inventory result data. Throughout the process, the first communication node may only be visible to the device identifier, and privacy data such as command information, command operation results, and inventory result data are all invisible to the first communication node. Thus, the protection of privacy data during the device operation process is achieved, avoiding the leakage of privacy data. The first communication node may instruct the second communication node under the condition of data privacy protection, and the second communication node may normally execute the corresponding command without the problem of privacy data leakage.

[0092] Figure 3 The flowchart of another communication method provided for an embodiment is as Figure 3 shown. The communication method described in the embodiments of the present application is applied to the second communication node. The method includes S210:

[0093] S210. Receive the first request message sent by the first communication node. The first request message is used to instruct the second communication node to execute a corresponding command. The first request message includes at least one device identifier and the invisible data corresponding to each device identifier. The invisible data is data invisible to the first communication node.

[0094] The second communication node receives the first request message sent by the first communication node. The first request message can be specified by the first communication node to be sent to this node, or can be sent by the first communication node to multiple second communication nodes in a broadcast form, and this device receives this first request message. The second communication node can execute corresponding commands according to the indication of the first request message. The first request message includes at least one device identifier and the invisible data corresponding to each device identifier. The invisible data is data invisible to the first communication node. After receiving the first request message, the second communication node parses the first request message to determine whether the device identifier it contains is the same as the identifier of this node. If they are the same, this node executes the corresponding command. For example, it executes the corresponding command according to the corresponding invisible data. The second communication node can perform processing such as decrypting the invisible data to determine the specific content of the data, and then execute the corresponding command according to the specific content.

[0095] In the communication method provided by the embodiments of the present application, the second communication node receives the first request message sent by the first communication node, and the second communication node executes the corresponding command according to the indication of the first request message. The first request message includes at least one device identifier and the invisible data corresponding to each device identifier. The invisible data is data invisible to the first communication node. When the second communication node determines that this node executes the corresponding command according to the device identifier, it can process the invisible data to determine the specific content of the invisible data and then execute the corresponding command. The invisible data is invisible to the first communication node and visible to the second communication node, thereby realizing the protection of privacy data during the device operation process, avoiding the leakage of privacy data. The first communication node can instruct the second communication node under the condition of data privacy protection, and the second communication node can normally execute the corresponding command without the problem of privacy data leakage.

[0096] In some embodiments, the invisible data includes the command information of the device.

[0097] In some embodiments, the method further includes:

[0098] Sending a first feedback message to the first communication node in response to the first request message;

[0099] Wherein, the first feedback message includes at least one of the following:

[0101] The invisible data of the second communication node. The invisible data of the second communication node is data invisible to the first communication node, and the invisible data of the second communication node includes the command operation result.

[0102] After receiving the first request message, the second communication node determines whether the node needs to execute the corresponding command operation according to the first request message. If the identifier of the node is the same as the device identifier in the first request message, that is, the device identifier in the first request message includes the identifier of the node, it is determined that the node needs to execute the corresponding operation command, then executes the corresponding command, generates the first feedback message according to the execution result, and sends the first feedback message to the first communication node. When generating the first feedback message, if the second communication node needs to feedback privacy data such as the result of the command operation, it encrypts the privacy data and performs other processing to form invisible data, and carries the invisible data in the first feedback message for feedback. When the second communication node performs feedback, it carries at least one of the device identifier of the node and the invisible data in the first feedback message for feedback.

[0103] In some embodiments, the invisible data is encapsulated in at least one protocol data unit or byte string.

[0104] In some embodiments, the protocol data unit is a non-access stratum data unit or an environmental Internet of Things device application layer protocol data unit

[0105] In the communication method provided by the embodiments of the present application, the second communication node receives the first request message sent by the first communication node, executes the corresponding command according to the indication of the first request message, and feeds back the first feedback message. The first feedback message includes at least one of the device identifier of the second communication node and the invisible data. The invisible data of the second communication node is invisible to the first communication node. Throughout the process, the first communication node can only see the device identifier, and privacy data such as the command operation result is invisible to the first communication node. Thus, the protection of privacy data during the device operation process is realized, and the leakage of privacy data is avoided. The first communication node can instruct the second communication node under the condition of data privacy protection, and the second communication node can normally execute the corresponding command without the problem of privacy data leakage.

For example, execute an inventory operation, execute a command operation, etc.

[0109] The first communication node sends the third request information to one or more fourth communication nodes. When the first communication node sends the third request information to the fourth communication node, it can send the third request information to one or more fourth communication nodes within the coverage area of the first communication node. The first communication node can send the third request information when certain conditions are met or a trigger is received. The third request information can be information received by the first communication node from other devices, that is, after the first communication node obtains the third request information, it forwards the third request information to the fourth communication node. It can also be that after the first communication node receives information from other devices, it processes the received information, such as recombination, to form the third request information. The third request information includes at least one device identifier and the invisible data corresponding to each device identifier. The device identifier is visible data. The third request information is used to indicate that the fourth communication node executes corresponding commands for the corresponding second communication node.

The invisible data can be the information required during the execution of the command or any data that needs to be transmitted. The invisible data is data invisible to the first communication node and the fourth communication node, that is, the first communication node and the fourth communication node cannot resolve the specific content of this part of the data, realizing the protection of privacy data and avoiding the leakage of privacy data.

The third request information includes at least one device identifier and the invisible data corresponding to each device identifier.

[0192] The communication process is described through the following embodiments:

[0193] Embodiment 1

[0194] Figure 9 An implementation example diagram of communication is provided. Taking the interaction process of the first communication node, the second communication node, and the third communication node as an example, the communication process of discovering a device first and then commanding the device is described. The first communication node may be a wireless access network AIoT reader, for example, a base station, the second communication node may be an AIoT device, and the third communication node may be a core network.

[0195] The third communication node and some second communication nodes have reached an agreement on the encryption and decryption methods for transmitting and sending secure data and the corresponding encryption and decryption keys for the relevant second communication nodes through pre-configuration or pre-negotiation. For example, the application services of the second communication node and the third communication node (such as RAN AIoT application services) can encrypt and decrypt the application data.

[0196] Step 1: The third communication node sends a second request message for the second communication node to the first communication node, for requesting the first communication node to execute corresponding commands for the corresponding second communication node. Among them, the second request message includes at least one of the following: data visible to the first communication node; data invisible to the first communication node. Among them:

[0197] The visible data of the first communication node includes the following: the device identifiers of at least one second communication node;

[0198] The invisible data of the first communication node includes: command information for at least one second communication node (Command information). (Among them, the command information includes at least one of the following: command type, such as operations like reading, querying, writing, etc.; the data corresponding to the command, such as the type of information to be read, the items to be queried, or the data to be written, etc. It is also possible that in some implementations, if the command type does not contain sensitive data, the command type can be placed in the visible data of the first communication node).

[0199] Note: In some embodiments, the invisible data of the first communication node can be encapsulated in at least one PDU (Protocol Data Unit), such as NAS (Non-Access Stratum) PDU, AIoT application layer PDU, etc. in the format of PDU, or encapsulated in at least one "OCTET STRING" container (Container). Generally, the invisible data of the first communication node here will be encrypted by the RAN AIoT application service sender on the third communication node side or the second communication node sender, and only the AIoT application service receiver or the second communication node receiver can decrypt and read it.

[0200] Note: In some embodiments, the invisible data of the first communication node can be understood as data that the first communication node cannot resolve the specific content of, that is, data that the RAN AIoT reader (base station, or base station and UE) cannot resolve the specific content of.

[0201] Step 2: After the first communication node receives the second request information sent by the third communication node, the first communication node broadcasts / sends the sixth request information to multiple second communication nodes within a certain coverage. The sixth request information can be an inventory message or an initial AIoT trigger message, used to discover the specified second communication nodes to be inventoried. The sixth request information includes at least one of the following:

[0202] Inventory indication and / or trigger indication, used to instruct the second communication node to return the device identifier (if it contains a trigger indication or only a trigger indication, it is used to instruct the second communication node to only need to feedback the device identifier, without the need to feedback other inventory result data or other invisible data of the first communication node; if it does not contain a trigger indication, the second communication node needs to feedback the device identifier and necessary other inventory result data or necessary invisible data of the first communication node);

[0203] The device identifiers of at least one second communication node to be responded to (if this item is not included, it can be used to instruct that all second communication nodes that receive this message should respond and feedback the device identifier).

[0204] Note that in some implementations, in order to discover devices in advance, the first communication node can independently decide to broadcast / send an inventory or initial trigger message to multiple second communication nodes within a certain coverage to discover devices. In this case, the first communication node sending the inventory or initial trigger message does not depend on whether it has received the message sent by the third communication node in the first step.

[0205] Step 3: The second communication node receives the sixth request information. If the device identifier of this second communication node belongs to the device identifiers of the second communication nodes to be responded to in the message, this second communication node sends sixth feedback information to the first communication node; or if the sixth request information does not contain the device identifiers of the second communication nodes to be responded to, all second communication nodes that receive the sixth request information send feedback sixth feedback information to the first communication node. (Note that before sending the sixth feedback information, it may also include a random access process or a connection process for the second communication node to access the first communication node).

[0206] Among them, the sixth feedback information includes at least one of the following: data visible to the first communication node; data invisible to the first communication node. Among them:

[0207] The data visible to the first communication node includes the following: the device identifier of this second communication node;

[0208] The data invisible to the first communication node includes the following: the inventory result data of this second communication node (such as the production date of the device, the device type, the positioning location where the device is located, etc.). (Note: If the message received by the second communication node contains a trigger indication or only a trigger indication, the RAN second communication node does not feedback the data invisible to the first communication node).

[0209] Step 4: The first communication node receives the sixth feedback information from the second communication node. The first communication node saves the device identifier of the device, that is, the first communication node discovers this second communication node, or the first communication node establishes an association relationship with this second communication node.

[0210] Step 5: The first communication node sends / broadcasts a first request information to the second communication node for at least one discovered second communication node, for requesting the second communication node to execute corresponding commands. Among them, the first request information includes at least one of the following: the device identifiers of at least one second communication node; the invisible data for at least one second communication node, and the invisible data is the data invisible to the first communication node. (Among them, the data invisible to the first communication node is the command information sent by the third communication node to the first communication node in the first step).

[0211] Step 6: When the second communication node receives the first request message, if the device identifier of this second communication node belongs to the device identifiers of the second communication nodes to be operated in the first request message, this second communication node executes the corresponding command in the first request message and sends a first feedback message to the first communication node, where the first feedback message includes at least one of the following: data visible to the first communication node; data invisible to the first communication node. Wherein:

[0212] The data visible to the first communication node includes the following: the identifier of this second communication node;

[0213] The data invisible to the first communication node includes the following: the command operation result of this second communication node. (Such as the read data, the query result; the feedback on whether the write is successful, etc.).

[0214] Step 7: After the first communication node receives one or more first feedback messages from the second communication nodes, according to the device identifiers fed back by the second communication nodes and the data invisible to the first communication node fed back, the first communication node sends a second feedback message to the third communication node to feedback the command operation result for the second communication node to the third communication node, where the second feedback message includes at least one of the following:

[0215] The device identifiers of at least one second communication node;

[0216] The data invisible to the first communication node: the data invisible to the first communication node fed back by at least one corresponding second communication node, and the invisible data is the data invisible to at least one first communication node. (That is, the command operation result, and / or the inventory result data).

[0217] Embodiment 2

[0218] Figure 10 Another implementation example diagram of communication is provided. Taking the interaction process of the first communication node, the second communication node, the third communication node, and the fourth communication node as an example, the communication process of discovering the device first and then commanding the device is described. The first communication node can be a base station, the second communication node can be an AIoT device, the third communication node can be a core network, the fourth communication node can be a user device, and the first communication node and the fourth communication node together serve as a wireless access network AIoT reader.

[0219] The third communication node and some second communication nodes have reached an agreement on the encryption and decryption methods for transmitting and sending secure data and the corresponding encryption and decryption keys for the relevant second communication nodes through pre-configuration or pre-negotiation. For example, the application services of the second communication node and the third communication node (such as the RAN AIoT application service) can encrypt / decrypt the application data.

[0220] Step 1: The third communication node sends fourth request information for the second communication node to the first communication node, for requesting the first communication node to execute corresponding commands for the corresponding second communication node. The fourth request information includes at least one of the following: data visible to the first communication node and the fourth communication node; data invisible to the first communication node and the fourth communication node.

[0221] Wherein:

[0222] The data visible to the first communication node and the fourth communication node includes the following: the device identifier of at least one second communication node and the user equipment (UE) ID of at least one user equipment for the device identifier of the second communication node.

[0223] The data invisible to the first communication node and the fourth communication node includes: command information for at least one second communication node. The information included in the command information can refer to Embodiment 1.

[0224] Step 2: The first communication node and the fourth communication node jointly act as an AIoT reader. After the first communication node receives the fourth request information sent by the third communication node, based on the specified user equipment ID in the fourth request information, the first communication node sends an RRC paging message to one or more corresponding fourth communication nodes in the RRC non-connected state (i.e., the idle state or the inactive state, RRC IDLE or RRC inactive) within a certain coverage area, or sends an RRC inventory message or an RRC AIoT initial trigger message to one or more corresponding fourth communication nodes in the RRC connected state. The message includes at least one of the following:

[0225] An inventory indication and / or a trigger indication, used to indicate that the second communication node returns the device identifier (if the trigger indication is included or only the trigger indication exists, it is used to indicate that the second communication node only needs to feedback the device identifier without returning other inventory result data or other invisible data; if the trigger indication is not included, the second communication node needs to feedback the device identifier and necessary other inventory result data or necessary invisible data);

[0226] The identifier of at least one second communication node to be responded to (if this item is not included, it can be used to indicate that all second communication nodes receiving this message should respond and feedback the device identifier).

[0227] Note that in some implementations, in order to discover devices in advance, the first communication node can independently decide to broadcast / send a paging message, an RRC inventory, or an RRC AIoT initial trigger message to multiple fourth communication node devices within a certain coverage area for device discovery. In this case, the first communication node's sending of the above messages does not depend on whether it has received the message sent by the third communication node in the first step.

[0228] Step 3: After the corresponding fourth communication node is successfully paged or receives the RRC inventory / AIoT initial trigger message, the fourth communication node broadcasts / sends a sixth request message to multiple second communication nodes within a certain coverage area to discover the specified second communication nodes to be inventoried. The sixth request message includes at least one of the following:

[0229] An inventory indication and / or a trigger indication for instructing the second communication node to return the device identifier (if the trigger indication is included or there is only the trigger indication, it is used to instruct the second communication node to only need to feedback the device identifier without needing to feedback other inventory result data; if the trigger indication is not included, the second communication node needs to feedback the device identifier and other inventory result data);

[0230] The device identifiers of at least one second communication node to be responded to (if this item is not included, it can be used to instruct that all second communication nodes that receive this message should respond and feedback the device identifier).

[0231] Step 4a: When the second communication node receives the sixth request message, if the device identifier of the second communication node belongs to the device identifiers of the second communication nodes to be responded to in the sixth request message, the second communication node sends a sixth feedback message to the first communication node; or if the sixth request message does not include the device identifiers of the second communication nodes to be responded to, all second communication nodes that receive the sixth request message send a sixth feedback message to the first communication node. The content items of the sixth feedback message sent by the second communication node are defined in the same way as in Step 3 of Embodiment 1 (Note that before sending the sixth feedback message, it may also include a random access process or a connection process for the second communication node to access the fourth communication node).

[0232] Step 4b: When the fourth communication node receives the sixth feedback message from the second communication node, the fourth communication node saves the device identifier of the device, that is, the first communication node discovers the second communication node, or the fourth communication node establishes an association relationship with the second communication node.

[0233] The fourth communication node receives the sixth feedback information of one or more second communication nodes, and the fourth communication node sends an RRC message to the first communication node to feedback the discovery results for at least one second communication node. The message includes at least one of the following: data visible to the first communication node and the fourth communication node; data invisible to the first communication node and the fourth communication node. Wherein:

[0234] The data visible to the first communication node and the fourth communication node includes the following: at least one second communication node ID;

[0235] The data invisible to the first communication node and the fourth communication node: the invisible data fed back by at least one corresponding second communication node, and the invisible data is the invisible data of at least one first communication node and the fourth communication node. (That is, the inventory result data).

[0236] Step 5: The first communication node receives the RRC feedback message of one or more fourth communication nodes. The first communication node saves the device identifier of the discovered second communication node fed back by the fourth communication node, and the device identifier of the fourth communication node corresponding to the discovery of the second communication node, that is, the first communication node and the corresponding fourth communication node discover the second communication node, or the first communication node and the corresponding fourth communication node establish an association relationship with the second communication node.

[0237] Step 6a: The first communication node sends a third request message to the fourth communication node corresponding to at least one discovered second communication node. The third request message can be an RRC message, and the third request message is used to request the second communication node to execute a corresponding command. The third request message includes at least one of the following: the device identifier of at least one second communication node; the invisible data for at least one second communication node, and the invisible data is the data invisible to the first communication node and the fourth communication node. (Wherein, the invisible data is the command information sent by the third communication node to the first communication node in the first step).

[0238] Step 6b: After receiving the third request message, the fourth communication node sends / broadcasts a fifth request message to the corresponding second communication node according to the device identifier of the second communication node in the third request message and the invisible data of the corresponding first communication node and the fourth communication node. The fifth request message can be a command message, which is used to request the second communication node to execute a corresponding command. The fifth request message includes at least one of the following: the device identifier of at least one second communication node; the invisible data for at least one second communication node, and the invisible data is the data invisible to the first communication node and the fourth communication node.

[0239] Step 7a: The corresponding second communication node receives the fifth request message from the fourth communication node. If the device identifier of the second communication node belongs to the device identifier of the second communication node to be operated in the fifth request message, the second communication node executes the corresponding command in the fifth request message and sends the fifth feedback message to the fourth communication node. The content items of the fifth feedback message sent by the second communication node are the same as those in step 6 of Embodiment 1.

[0240] Step 7b: The fourth communication node receives one or more fifth feedback messages from the second communication nodes. According to the device identifiers and the invisible data fed back by the second communication nodes, the fourth communication node sends the third feedback message to the first communication node, feeding back the command operation result for the second communication node. The third feedback message includes at least one of the following:

[0241] The device identifiers of at least one second communication node;

[0242] The data invisible to the first communication node and the fourth communication node, including: the invisible data of at least one corresponding second communication node, and the invisible data is the data invisible to at least one first communication node and the fourth communication node (i.e., the inventory result data).

[0243] Step 8: The first communication node receives one or more third feedback messages from the fourth communication nodes. According to the device identifiers of the second communication nodes fed back by the fourth communication nodes and the data invisible to the first communication node and the fourth communication node of the corresponding devices, the first communication node sends the fourth feedback message to the third communication node, feeding back the command operation result for the second communication node to the third communication node. The fourth feedback message includes at least one of the following:

[0244] The device identifiers of at least one second communication node;

[0245] The data invisible to the first communication node and the fourth communication node, including: the invisible data of at least one corresponding second communication node, and the invisible data is the data invisible to at least one first communication node and the fourth communication node. (i.e., the command operation result, and / or the inventory result data).

[0247] Figure 11 Another implementation example diagram of communication is provided. Taking the interaction process among the first communication node, the second communication node, and the third communication node as an example, the communication process of simultaneously inventorying and operating the devices is described. The first communication node may be a wireless access network AIoT reader, for example, a base station, the second communication node may be an AIoT device, and the third communication node may be a core network.

[0248] The third communication node and some of the second communication nodes have reached an agreement on the encryption and decryption methods for transmitting and sending secure data by the relevant second communication nodes and the corresponding encryption and decryption keys through pre-configuration or pre-negotiation. For example, the application services of the second communication node and the third communication node (such as RAN AIoT application services) can encrypt / decrypt the application data.

[0249] Step 1: The third communication node sends a seventh request message to the first communication node for the second communication node, used to request the first communication node to execute corresponding commands for the corresponding second communication node. The content items of the seventh request message can refer to Step 1 of Embodiment 1.

[0250] Step 2: After the first communication node, as an AIoT reader, receives the seventh request message sent by the third communication node, the first communication node broadcasts / sends an eighth request message to the corresponding multiple second communication nodes within a certain coverage area. The eighth request message contains at least one of the following:

[0251] Inventory indication;

[0252] Device identifiers of at least one second communication node to be responded to;

[0253] Invisible data for at least one second communication node, where the invisible data is data invisible to the first communication node. (Among them, the data invisible to the first communication node is the command information sent by the third communication node to the first communication node in the first step).

[0254] Step 3: When the corresponding second communication node receives the eighth request message, if the device identifier of this second communication node belongs to the device identifiers of the second communication nodes to be responded to in the eighth request message, this second communication node executes the corresponding command in the eighth request message (the command is included in the data invisible to the first communication node), and sends an eighth feedback message to the first communication node. The eighth feedback message contains at least one of the following: data visible to the first communication node; data invisible to the first communication node. Among them:

[0255] The data visible to the first communication node includes the following: the device identifier of this second communication node;

[0257] Step 4: The first communication node receives the eighth feedback information from the second communication node, and the first communication node saves the device identifier of the second communication node, that is, the first communication node discovers the second communication node, or the first communication node establishes an association relationship with the second communication node.

[0258] Step 5: The first communication node receives the eighth feedback information of one or more second communication nodes. According to the device identifier feedback by the second communication node and the data invisible to the first communication node feedback, the first communication node sends the seventh feedback information to the third communication node, and feeds back the command operation result for the second communication node to the third communication node, where the seventh feedback information includes at least one of the following:

[0259] The device identifiers of at least one second communication node;

[0260] The invisible data of at least one second communication node, and the invisible data is the data invisible to at least one first communication node.

[0261] Embodiment 4

[0262] Figure 12 Another implementation example diagram of communication is provided. Taking the interaction process of the first communication node, the second communication node, the third communication node, and the fourth communication node as an example, the communication process of inventorying and operating the device simultaneously is described. The first communication node may be a base station, the second communication node may be an AIoT device, the third communication node may be a core network, the fourth communication node may be a user equipment, and the first communication node and the fourth communication node jointly serve as a wireless access network AIoT reader.

[0263] The third communication node and some second communication nodes have reached an agreement on the encryption and decryption methods for transmitting and sending secure data and the corresponding encryption and decryption keys for the relevant second communication nodes through pre-configuration or pre-negotiation. For example, the application services of the second communication node and the third communication node (such as RAN AIoT application services) can encrypt / decrypt the application data.

[0264] Step 1: The third communication node sends the ninth request information for the second communication node to the first communication node, for requesting the first communication node to execute corresponding commands for the corresponding second communication node, where the content items of the ninth request information can refer to Step 1 of Embodiment 2.

[0265] Step 2: The first communication node and the fourth communication node jointly serve as an AIoT reader. After the first communication node receives the ninth request message sent by the third communication node, based on the specified user equipment ID in the ninth request message, the first communication node sends a tenth request message to one or more corresponding fourth communication nodes in a certain coverage area that are in the RRC non-connected state (i.e., the idle state or the inactive state, RRC IDLE or RRC inactive). The tenth request message can be an RRC paging message, or the first communication node sends a tenth request message to one or more corresponding fourth communication nodes in the RRC connected state. The tenth request message can be an RRC message. The tenth request message is used to instruct the fourth communication node to execute corresponding commands for the corresponding second communication node. The tenth request message includes at least one of the following:

[0266] Inventory indication;

[0267] The device identifier of at least one second communication node to be responded to;

[0268] Invisible data for at least one second communication node. The invisible data is data that is invisible to the first communication node and the fourth communication node. (Among them, the data that is invisible to the first communication node and the fourth communication node is the data sent by the third communication node to the first communication node in the first step, that is, the command message).

[0269] Step 3: After the corresponding fourth communication node is successfully paged, or the corresponding fourth communication node receives the tenth request message, according to the device identifier of the second communication node in the tenth request message and the invisible data for at least one second communication node corresponding to it, the fourth communication node broadcasts / sends an eleventh request message to multiple second communication nodes in a certain coverage area. The eleventh request message includes at least one of the following:

[0270] Inventory indication;

[0271] The device identifier of at least one second communication node to be responded to;

[0272] Invisible data for at least one second communication node. The invisible data is data that is invisible to the first communication node and the fourth communication node.

[0273] Step 4a: When the corresponding second communication node receives the eleventh request message, if the device identifier of this second communication node belongs to the device identifiers of the second communication nodes to be responded to in the eleventh request message, this second communication node executes the corresponding command in the eleventh request message (this command contains data invisible to the first communication node and the fourth communication node), and sends the eleventh feedback message to the fourth communication node, where the eleventh feedback message contains at least one of the following: data visible to the fourth communication node; data invisible to the fourth communication node. Among them:

[0274] The data visible to the fourth communication node includes the following: the device identifier of this second communication node;

[0275] The data invisible to the fourth communication node includes at least one of the following: the command operation result of this second communication node (such as the read data, the query result; the feedback on whether the write is successful, etc.); the inventory result data of this device (such as the device production date, the device type, the positioning location where the device is located, etc.).

[0276] Step 4b: The fourth communication node sends the tenth feedback message to the first communication node according to the eleventh feedback message; the tenth feedback message contains at least one of the following: data visible to the first communication node; data invisible to the first communication node. Among them:

[0277] The data visible to the first communication node includes the following: the device identifier of the second communication node;

[0278] The data invisible to the first communication node includes at least one of the following: the command operation result of the second communication node (such as the read data, the query result; the feedback on whether the write is successful, etc.); the inventory result data of the second communication node (such as the device production date, the device type, the positioning location where the device is located, etc.).

[0279] Step 5: The first communication node receives one or more tenth feedback messages from the fourth communication node. For example, the RRC feedback message. The first communication node saves the device identifier of the second communication node found in the feedback of the fourth communication node, and the device identifier of the fourth communication node corresponding to the discovery of this second communication node, that is, the first communication node and the corresponding fourth communication node have discovered this second communication node, or this first communication node and the corresponding fourth communication node have established an association relationship with this second communication node.

[0280] Step 6: The first communication node receives the tenth feedback information of one or more fourth communication nodes. According to the device identifier of the second communication node feedback by the fourth communication node and the data invisible to the first communication node and the fourth communication node corresponding to the device, the first communication node sends the ninth feedback information to the third communication node, and feeds back the command operation result for the second communication node to the third communication node, where the ninth feedback information includes at least one of the following:

[0281] The device identifiers of at least one second communication node;

[0282] The invisible data of at least one first communication node: The invisible data is the data invisible to at least one first communication node and the fourth communication node.

[0283] When the first communication node and the fourth communication node jointly act as a wireless access network AIoT reader, the invisible data is the invisible data of the first communication node and the fourth communication node. Since some information may only be sent to the first communication node and the fourth communication node, therefore, during the information transmission process, for the data only sent to the first communication node or the fourth communication node, it can be invisible only to the first communication node or the fourth communication node. For example, when the third request information is only sent to the fourth communication node, the invisible data in the third request information is the data invisible to the fourth communication node.
