Description

A communication method, communication device and storage medium

[0001] This application claims priority to Chinese Patent Application No. 202411599332.6, filed with the State Intellectual Property Office of China on November 8, 2024, entitled "A Communication Method, Communication Device and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method, communication device and storage medium. Background Technology

[0003] Ambient Internet of Things (AIoT) devices refer to intelligent devices that connect physical environment-related equipment to the internet through embedded systems, sensors, and communication technologies. These devices enable the collection, transmission, processing, and analysis of environmental data, as well as interaction and collaborative work with other devices or systems. Due to their advantages such as self-powered operation, low power consumption, low cost, ease of deployment, and wide applicability, AIoT terminal devices are now widely used in daily production and life.

[0004] However, if AIoT devices currently communicate using existing processes based on Long Term Evolution (LTE) or 5G technologies, it results in high terminal power consumption and network signaling overhead, failing to meet the communication requirements of AIoT devices. To adapt to the communication needs of AIoT devices, a Control Plane (CP) optimized transmission scheme has been proposed. This scheme uses control plane signaling to transmit service data between AIoT devices and the network, thereby reducing terminal power consumption and network signaling overhead during communication.

[0005] To achieve an optimized transmission scheme for the control plane of AIoT devices, a connection corresponding to the AIoT device needs to be established between the core network elements and the radio access network nodes to enable interaction between the AIoT device and the core network. However, existing technologies do not provide a scheme for establishing this connection between the core network elements and the radio access network nodes. Summary of the Invention

[0006] This application provides a communication method, communication device, and storage medium, with the aim of establishing a connection between network elements of the core network and wireless access network nodes corresponding to AIoT devices.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] A first aspect of this application provides a communication method applied to a first network element, the method comprising:

[0009] Send a first connection establishment request to the wireless access network node. The first connection establishment request includes the core network identification information of the first connection allocated by the first network element and the identification information of the first network element. The first connection is used to transmit environmental Internet of Things (AIoT) service signaling or data. The core network identification information of the first connection is used to identify the first connection.

[0010] A first connection establishment response is received from the radio access network node. The first connection establishment response includes radio access network identification information of the first connection allocated by the radio access network node and identification information of the radio access network node. The radio access network identification information of the first connection is used to identify the first connection.

[0011] In the above implementation scheme, the first network element can send a first connection establishment request carrying the core network identification information of the first connection to the radio access network node, and can receive a first connection establishment response carrying the radio access network identification information of the first connection from the radio access network node. This enables the first network element and the radio access network node to store the core network identification information and the radio access network identification information of the first connection, respectively. This completes the construction of the connection between the core network element and the radio access network node corresponding to the AIoT device, i.e., the first connection. This facilitates the implementation of the control plane optimized transmission scheme for the AIoT device, reducing the terminal power consumption and network signaling overhead of the AIoT device during communication.

[0012] In one possible implementation of the first aspect of this application, the first connection corresponds to multiple AIoT devices. In the above implementation, the first connection established between the first network element and the wireless access network node can correspond to multiple AIoT devices; that is, the first connection can be a shared connection among multiple AIoT devices. By establishing a shared first connection among multiple AIoT devices, the number of connections required for each AIoT device can be significantly reduced, thereby reducing the maintenance cost of the first connection and effectively improving the utilization rate of network resources.

[0013] In one possible implementation of the first aspect of this application, the relationship between the plurality of AIoT devices satisfies at least one of the following: the plurality of AIoT devices correspond to the same target coverage area of ​​the same radio access network node; the plurality of AIoT devices correspond to the same service request; the plurality of AIoT devices correspond to the same application function; the plurality of AIoT devices correspond to the same service type. In the above implementation, the plurality of AIoT devices corresponding to the first connection can be AIoT devices within the target coverage area of ​​the same radio access network node, or AIoT devices corresponding to the same service request, or AIoT devices corresponding to the same application function, or AIoT devices corresponding to the same service type. That is, a first connection can be established to allow multiple associated AIoT devices to share resources, thereby reducing the maintenance cost of the first connection and effectively improving the utilization rate of network resources.

[0014] In one possible implementation of the first aspect of this application, if the plurality of AIoT devices correspond to the same target coverage area of ​​the wireless access network node, the first connection establishment response further includes first indication information, which is used to indicate the target coverage area of ​​the wireless access network node. In the above implementation, if the plurality of AIoT devices corresponding to the first connection correspond to the same target coverage area of ​​the wireless access network node, the first connection establishment response from the wireless access network node may also carry first indication information for indicating the target coverage area of ​​the wireless access network node, enabling the first network element to determine the specific coverage area of ​​the plurality of AIoT devices.

[0015] In one possible implementation of the first aspect of this application, after receiving the first connection establishment response from the radio access network node, the method further includes: sending a first AIoT service request to the radio access network node based on the first connection, the first AIoT service request including core network identification information of the first connection, radio access network identification information of the first connection, first task identification information, and device information of the target AIoT device; and receiving a first AIoT service response from the radio access network node based on the first connection, the first AIoT service response including core network identification information of the first connection, radio access network identification information of the first connection, first task identification information, device information of the target AIoT device, and first service data. In the above implementation, after successfully establishing the first connection, and when the established first connection corresponds to multiple AIoT devices, the first network element can send the first AIoT service request to the radio access network node based on the established first connection. The first AIoT service request can carry the device information of the target AIoT device, and the first AIoT service response can be received from the radio access network based on the established first connection. This facilitates the implementation of an optimized transmission scheme for the control plane of the AIoT device, reducing terminal power consumption and network signaling overhead during communication.

[0016] In one possible implementation of the first aspect of this application, a second indication information is sent to the radio access network based on the first connection. The second indication information is used to instruct the radio access network node to unbind the first task identifier information from the first connection. In the above implementation, after the first network element completes a service related to the first AIoT service request based on the first connection, it can instruct the radio access network to unbind the first task identifier information in the first AIoT service request from the first connection, allowing the first connection to be used for the transmission of data related to other AIoT services.

[0017] In one possible implementation of the first aspect of this application, the first connection corresponds to a single target AIoT device, and the first connection establishment request further includes the identification information of the target AIoT device. In the above implementation, the first connection established between the first network element and the wireless access network node can correspond to a single target AIoT device; that is, the first connection can be a connection unique to a single target AIoT device, used only for transmitting AIoT service data related to the target AIoT device. This improves the security of AIoT service data and facilitates independent management of the connection corresponding to each AIoT device.

[0018] In one possible implementation of the first aspect of this application, sending the first connection establishment request to the radio access network node includes: if the target AIoT device is a verified device, sending the first connection establishment request to the radio access network node. In the above implementation, the first network element can establish a corresponding first connection for the target AIoT device by sending the first connection establishment request after verifying the validity of the target AIoT device's identity, thereby avoiding establishing a corresponding first connection for an invalid target AIoT device and improving the utilization rate of network resources.

[0019] In one possible implementation of the first aspect of this application, before sending the first connection establishment request to the radio access network node, the method further includes: sending a second AIoT service request to the radio access network node, the second AIoT service request including a first protocol layer data packet and second task identification information, the first protocol layer data packet encapsulating identification information of the target AIoT device; receiving a second AIoT service response from the radio access network node, the second AIoT service response including the second task identification information, third indication information, and second service data, the third indication information being used to instruct the first network element to establish a first connection, and the second service data including the identification information of the target AIoT device. In the above implementation scheme, before the first network element sends a first connection establishment request to the wireless access network node to establish the first connection corresponding to the target AIoT device, the wireless access network node can obtain a first protocol layer data packet containing the identification information of the target AIoT device based on the second AIoT service request sent by the IoT network element. When it is determined that the target AIoT device has not yet established the corresponding first connection, the wireless access network node sends the identification information of the target AIoT device and a third indication information instructing the first network element to establish the first connection based on the second AIoT service response, so that the first network element can obtain the identification information of the target AIoT device based on the second AIoT service response to establish the first connection corresponding to the target AIoT device.

[0020] In one possible implementation of the first aspect of this application, the first connection establishment request further includes fourth indication information, which is used to indicate the timing of releasing the first connection. In the above implementation, the first connection establishment request sent by the first network element to the radio access network may also carry fourth indication information indicating the timing of releasing the first connection. This allows the radio access network to determine when to release the first connection, thereby facilitating the maintenance and management of the first connection and reducing its maintenance costs.

[0021] In one possible implementation of the first aspect of this application, the fourth indication information includes at least one of a first indication sub-information, a second indication sub-information, and a third indication sub-information; the first indication sub-information is used to indicate a release timer, which triggers the radio access network node to release the first connection upon expiration; the second indication sub-information is used to indicate a data reporting period or a data reporting count, whereby the data reporting period indicates the period during which the radio access network node receives service data, and the data reporting count indicates the number of times the radio access network node receives service data; the third indication sub-information is used to instruct the radio access network node to maintain the first connection until a release instruction for the first connection is received. In the above implementation, the first network element can specifically indicate the release timing of the first connection using these three indication sub-information pieces, enabling the radio access network to determine when to release the first connection, thereby facilitating the maintenance and management of the first connection and reducing its maintenance costs.

[0022] In one possible implementation of the first aspect of this application, the first connection establishment request further includes at least one of the device information and service type of the target AIoT device. In the above implementation, the first connection establishment request sent by the first network element to the radio access network node may also carry at least one of the device information and service type of the target AIoT device, enabling the radio access network node to establish a device context based on the device information of the target AIoT device, and to determine the service type of the service data to be carried by the first connection after its establishment.

[0023] A second aspect of this application provides a communication method applied to a wireless access network node, the method comprising:

[0024] Receive a first connection establishment request from a first network element. The first connection establishment request includes the core network identification information of the first connection allocated by the first network element and the identification information of the first network element.

[0100] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The terminology used in the following embodiments is for the purpose of describing specific embodiments only and is not intended to be a limitation of this application. As used in the specification and appended claims of this application, the singular expressions "a," "an," "the," "the," "the," and "this" are intended to also include expressions such as "one or more," unless the context clearly indicates otherwise. It should also be understood that in the embodiments of this application, "one or more" refers to one, two, or more; "and / or" describes the relationship between related objects, indicating that three relationships may exist; for example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0101] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0102] The "multiple" mentioned in the embodiments of this application refers to two or more. It should be noted that in the description of the embodiments of this application, terms such as "first" and "second" are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance, nor should they be construed as indicating or implying order.

[0103] The embodiments of this application are applied to communication systems in the field of environmental Internet of Things, such as: Global System for Mobile Communications (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, 5th Generation (5G) system or New Radio (NR) system, and future communication systems.

[0104] The next-generation mobile communication network architecture defined by the 3GPP standards group is called the 5G network architecture. This architecture not only supports wireless technologies defined by the 3GPP standards group, such as LTE, to access the 5G core network (5GC), but also supports non-3GPP access technologies through non-3GPP interworking functions (N3IWF), trusted non-3GPP gateway functions (TNGF), trusted WLAN interworking functions (TWIF), or next-generation packet data gateways (NG-PDG) to access the 5GC. The core network functions are divided into user plane functions (UPF) and control plane functions (CPF). UPF is mainly responsible for packet forwarding, quality of service (QoS) control, and billing information statistics. CPF is primarily responsible for user registration and authentication, mobility management, and issuing packet forwarding policies and QoS control policies to UPF. It can be further subdivided into access and mobility management function (AMF) and session management function (SMF).

[0105] Core network equipment includes, for example, the Mobility Management Entity (MME) and the Broadcast Multicast Service Center (BMSC), or it may include corresponding functional entities in the 5G system, such as the core network control plane (CP) or user plane (UP) network functions, such as the SMF and AMF. The core network control plane can also be understood as the core network control plane function (CPF) entity.

[0106] Communication systems in the environmental IoT field include a first device and a second device. An example of such a system is shown in Figure 1, which includes a core network 11 and a radio access network node 12. The first device can be a device on the core network (CN) side used to provide network communication functions; in some cases, it is also called a network element. The first device can be a core network unit in the environmental IoT field. A core network unit can be a functional unit within the core network, including but not limited to access and mobility management function units or session management function units. It can also be a newly added first network element in the core network, also known as an Ambient Internet of Things Net Function (AIoT NF). It should be noted that an AIoT NF can be a new network element added to perform AIoT services, or it can be a network element coexisting with the AMF. That is, the AMF can be modified to possess the functions required for an AIoT NF. The interface between the first network element and the radio access network node can be called a Next Generation-like (NG-like) interface or an AIoT-NG interface.

[0107] The second device can typically be a base station (including functional units of a base station, or a combination of functional units of a base station) or other nodes in the radio access network, such as terminal equipment. The radio access network (RAN) is a network composed of multiple 5G-RAN nodes, implementing radio physical layer functions, resource scheduling and radio resource management, radio access control, and mobility management functions. The 5G-RAN connects to the user plane interface N3 and the UPF for transmitting data from terminal equipment; it also establishes a control plane signaling connection with the AMF through the control plane interface N2 for implementing functions such as radio access bearer control. The RAN can be any device with radio transceiver capabilities, including but not limited to 5G node base stations (gNBs), evolved Node Base Stations (eNBs), access points (APs), World Interoperability for Microwave Access Base Stations (WiMAX BSs), transmission receiving points (TRPs), radio relay nodes, and radio backhaul nodes.

[0108] The access network device in this application embodiment, i.e., the network device of the access network, can also be a device used to communicate with terminal devices. The access network device can be a base transceiver station (BTS) in a global system of mobile communication (GSM) or code division multiple access (CDMA), a node base (NB) in a wideband code division multiple access (WCDMA) system, an evolved node base (eNB) in an LTE system, or a radio controller in a cloud radio access network (CRAN) scenario. Alternatively, the access network device can be a relay station, access point, vehicle-mounted device, wearable device, or access network device in a future 5G network or an access network device in a future evolved PLMN network, etc. The embodiments of this application are not limited to these.

[0109] In NR, the base station's functionality is divided into two parts, known as centralized unit (CU) - distributed unit (DU) separation. From a protocol stack perspective, the CU includes the Radio Resource Control (RRC) layer and Packet Data Convergence Protocol (PDCP) layer of the LTE base station, while the DU includes the Radio Link Control (RLC) layer, Media Access Control (MAC) layer, and Physical (PHY) layer of the LTE base station. In a typical 5G base station deployment, the CU and DU are physically connected via fiber optic cable, and logically share a specially defined F1 interface for communication between them. Functionally, the CU is primarily responsible for radio resource control and configuration, inter-cell mobility management, and bearer management. The DU is primarily responsible for scheduling, physical signal generation, and transmission.

[0110] Among them, the aforementioned base stations can be macro base stations, micro base stations, pico base stations, small stations, relay stations, balloon stations, etc.

[0111] Referring to Figure 2, this figure is an example of another communication system architecture applicable to embodiments of this application.

[0112] Session Management Function (SMF): Primarily responsible for the control plane functions of terminal device session management, including the selection and control of user plane functions (UPF), Internet Protocol (IP) address allocation, session QoS management, and obtaining policy and charging control (PCC) policies from the PCF.

[0113] User plane function (UPF): As the anchor point for protocol data unit (PDU) session connections, it is responsible for filtering data packets from terminal devices, transmitting / forwarding data, rate control, generating billing information, and providing connectivity to the data network (DN).

[0114] Policy control function (PCF): Provides configuration policy information for terminal devices, provides policy information for network control plane elements, such as SMF elements, to manage and control terminal devices; and generates access policies and QoS flow control policies for terminal devices.

[0115] Application function (AF): Interacts with core network elements to provide services. For example, it interacts with PCF to control service policies, interacts with NEF to obtain network capability information or provide application information to the network, and provides data network access point information to PCF to generate routing information for corresponding data services.

[0116] Unified Data Management (UDM) (not shown in the figure): One of the network functions related to user data in the core network, mainly responsible for the management of user identification, subscription data, authentication data, and user service element registration management.

[0117] Authentication Server Function (AUSF) (not shown in the diagram): Responsible for authentication. Specifically, in mobile communication technology, AUSF is a functional entity representing a set of authentication algorithms, responsible for processing and executing algorithms related to network user authentication and session security.

[0118] It should be noted that the aforementioned "network element" can also be referred to as an entity, device, apparatus, or module, etc., and this application does not specifically limit it. Furthermore, in this application, for ease of understanding and explanation, the description of "network element" is omitted in some descriptions. For example, NEF network element is abbreviated as NEF. In this case, "NEF" should be understood as NEF network element or NEF entity. The following omits descriptions of the same or similar cases.

[0119] The names of the network elements included in Figure 2 are merely names and do not limit the function of the network element itself. In 5G networks and other future networks, the above-mentioned network elements may also have other names, and this application embodiment does not specifically limit them. For example, in 6G networks, some or all of the above-mentioned network elements may use the terminology from 5G, or they may have other names, etc. This is explained uniformly here and will not be repeated below.

[0120] The network elements in Figure 2 do not necessarily have to exist at the same time; the required network elements can be determined based on the needs.

[0121] The aforementioned network elements or functions can be network components in hardware devices, software functions running on dedicated hardware, or virtualization functions instantiated on platforms such as cloud platforms.

[0122] In the embodiments provided in this application, the terminal device can be of various forms, such as a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, an in-vehicle terminal device, a wireless terminal device in self-driving technology, a wireless terminal device in remote medical care, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, a wearable terminal device, etc. The terminal device may also be referred to as a terminal device, user equipment (UE), access terminal device, in-vehicle terminal device, industrial control terminal device, UE unit, UE station, mobile station, mobile station, remote station, remote terminal device, mobile device, UE terminal device, terminal device, wireless communication device, UE agent, or UE device, etc. The terminal device can also be a fixed terminal device or a mobile terminal device.

[0123] In communication systems, Ambient Internet of Things (AIoT) devices refer to intelligent devices that connect physical environment-related equipment to the internet through embedded systems, sensors, and communication technologies. These devices enable the collection, transmission, processing, and analysis of environmental data, as well as interaction and collaborative work with other devices or systems. Due to their advantages such as self-powered operation, low power consumption, low cost, ease of deployment, and wide applicability, AIoT terminal devices are now widely used in daily production and life.

[0124] In the use of environmental IoT terminal devices, it is often necessary to transmit service data such as paging or commands to the environmental IoT terminal devices. Specifically, as shown in Figure 3A, the base station can directly send service requests to the environmental IoT terminal devices; as shown in Figure 3B, the base station can also send service requests to the environmental IoT terminal devices through intermediate nodes, where the intermediate nodes can specifically be mobile terminal devices.

[0125] As an environment-enabled IoT technology, AIoT, combined with cellular networks, offers lower power consumption or even zero power consumption compared to existing narrowband Internet of Things (NB-IoT) technologies. This makes passive cellular networks suitable for more IoT scenarios, enabling interconnectivity across all industries and creating a new market worth hundreds of billions of connections. Compared to traditional LTE networks and existing 5G networks, the significant differences in networks used for AIoT devices lie in: a large number of terminals, limited terminal capabilities, high energy efficiency requirements, and a focus on small packet transmission and reception.

[0126] For AIoT devices, the current LTE / 5G process results in excessively high terminal power consumption and network signaling overhead when sending a single unit of data. On the one hand, in order to send or receive a small amount of data, AIoT devices need to transition from an idle state to a connected state, and the network signaling overhead consumed is far greater than the data payload itself. Therefore, the 3GPP R19 stage considers that AIoT devices do not have an RRC state. On the other hand, the complex signaling process based on LTE / 5G also brings significant overhead to the power consumption of AIoT devices.

[0127] To meet the access requirements of AIoT devices, 3GPP enhanced the overall network architecture and processes, proposing optimized transmission schemes for the Control Plane (CP) and User Plane (UP). The basic principle of the CP-optimized transmission scheme is to transmit service data between AIoT devices and the network through control plane signaling. Following this scheme, AIoT devices can carry Protocol Data Units (PDUs) from the Non-Access Stratum (NAS) or Application Layer in the control plane signaling, encapsulating AIoT service data within these PDUs. This achieves the goal of transmitting user plane data directly using the control plane without establishing a user plane bearer. Considering the weak device characteristics of AIoT devices, the CP data transmission scheme became a key focus of discussion during the 3GPP R19 standard research phase.

[0128] To achieve an optimized transmission scheme for the control plane of AIoT devices, a connection corresponding to the AIoT device needs to be established between the core network elements and the radio access network nodes to enable interaction between the AIoT device and the core network. However, existing technologies do not provide a scheme for establishing this connection between the core network elements and the radio access network nodes.

[0129] To make the technical solution of this application clearer and easier to understand, the communication method of multimodal services in the embodiments of this application is described below with reference to the accompanying drawings. The embodiments of this application are applicable to the data transmission process in the field of environmental Internet of Things. In the embodiments of this application, the data transmission between a first network element and a wireless access network node is taken as an example, such as the data transmission between a single first network element and a wireless access network node.

[0130] Please refer to Figure 4. Figure 4 shows a schematic diagram of the first interaction process between the first network element and the wireless access network node provided in an embodiment of this application. The communication method provided in this embodiment mainly includes the following steps:

[0131] 401. The first network element sends a first connection establishment request to the wireless access network node.

[0132] The first connection establishment request includes the core network identification information of the first connection allocated by the first network element and the identification information of the first network element. The first connection is used to transmit environmental IoT (AIoT) service signaling or data, and the core network identification information of the first connection is used to identify the first connection.

[0133] In this embodiment, the first network element can trigger the establishment of a first connection by sending a first connection establishment request to the radio access network node. The first connection can be a connection between the first network element and the radio access network node corresponding to an AIoT device in the environment; that is, the first connection can be used to transmit service signaling or data related to the AIoT device, such as IP data or non-IP data, between the first network element and the radio access network node. Specifically, the first connection can be described as an AIoT-NG connection or an NG-like connection. The first connection establishment request can specifically be an AIoT-NG Setup Request or an Initial device context setup request.

[0134] The first connection establishment request may carry the core network identification information and the identification information of the first network element. The core network identification information of the first connection is pre-assigned by the first network element and is used to identify the first connection; for example, the core network identification information of the first connection may specifically be a CN NGAP ID (Core Network Next Generation Access Protocol Identity). The identification information of the first network element may be information used to identify the identity of the first network element, such as an AIOT NF ID or AIOT NF Name. Furthermore, the first connection establishment request may also carry a list of Public Land Mobile Networks (PLMNs) supported by the first network element, etc., but this embodiment of the application does not limit this.

[0135] Understandably, after determining that no first connection corresponding to the AIoT device has been established between the first network element and the radio access network node, the first network element can trigger the establishment of the first connection by sending a first connection establishment request carrying the core network identification information of the first connection to the radio access network node. For example, after receiving an AIoT service request, it can determine whether the AIoT device corresponding to the AIoT service request has established a corresponding first connection. If it is determined that the first connection corresponding to the AIoT device has not been established, core network identification information for identifying the corresponding first connection can be allocated to the AIoT device, and the core network identification information of the first connection can be sent to the radio access network node through a first connection establishment request to facilitate the establishment of the first connection corresponding to the AIoT device.

[0136] In one possible implementation of this application embodiment, the first connection corresponds to multiple AIoT devices. In this embodiment, the first connection established between the first network element and the wireless access network node can correspond to multiple AIoT devices; that is, the first connection can be a connection shared by multiple AIoT devices. Specifically, the first network element can assign the same core network identifier information for the first connection to multiple AIoT devices and trigger the establishment of a shared first connection through a first connection establishment request. By establishing a shared first connection for multiple AIoT devices, the number of connections established for each AIoT device can be significantly reduced, thereby reducing the maintenance cost of the first connection and effectively improving the utilization rate of network resources. It is understood that the advantage of establishing a shared first connection for multiple AIoT devices lies in the smaller number of connections established, lower maintenance costs, and improved network resource utilization, while also reducing network latency from frequent connection teardowns and rebuilds.

[0137] In one possible implementation of this application embodiment, the relationship between the plurality of AIoT devices satisfies at least one of the following: the plurality of AIoT devices correspond to the target coverage area of ​​the same wireless access network node; the plurality of AIoT devices correspond to the same service request; the plurality of AIoT devices correspond to the same application function; the plurality of AIoT devices correspond to the same service type.

[0138] In this embodiment, when the first connection corresponds to multiple AIoT devices, these multiple AIoT devices can be AIoT devices within the target coverage area of ​​the same radio access network node, AIoT devices corresponding to the same service request, AIoT devices corresponding to the same application function, or AIoT devices corresponding to the same service type. That is, a first connection can be established for multiple associated AIoT devices to share, thereby reducing the maintenance cost of the first connection and effectively improving the utilization of network resources. It is understood that the first network element can construct a first connection shared by multiple AIoT devices within the target coverage area of ​​the same radio access network node, or it can construct a first connection shared by multiple AIoT devices for a single service request, or it can construct a first connection shared by multiple AIoT devices for a single application function, or it can construct a first connection shared by multiple AIoT devices for the same service type.

[0139] In one possible implementation of this application embodiment, the first connection corresponds to a single target AIoT device, and the first connection establishment request further includes the identification information of the target AIoT device. In this application embodiment, the first connection established between the first network element and the radio access network node can correspond to a single target AIoT device; that is, the first connection can be a connection unique to a single target AIoT device, used only for transmitting AIoT service data related to the target AIoT device. This improves the security of AIoT service data and facilitates independent management of the connection corresponding to each AIoT device. It is understood that when the first network element triggers the establishment of a first connection corresponding to a single target AIoT device, the first connection establishment request sent by the first network element to the radio access network node can also carry the identification information of the target AIoT device, so that the radio access network node can determine which specific target AIoT device the first connection corresponds to. The identification information of the target AIoT device can be, for example, a Device ID. It is understood that the first network element can obtain the identification information of the target AIoT device based on the received AIoT service request or AIoT service response.

[0140] In one possible implementation of this application embodiment, the first connection establishment request further includes at least one of the target AIoT device's device information and service type. In this application embodiment, if the first connection corresponds to a single target AIoT device, the first connection establishment request sent by the first network element to the radio access network node may also carry at least one of the target AIoT device's device information and service type, enabling the radio access network node to establish a device context based on the target AIoT device's device information, and to determine the service type of the service data to be carried by the first connection after its establishment. The service type can be inventory, command, or inventory + command. The target AIoT device's device information may include the AF information to which the device belongs, such as AF ID, device type, device security capabilities, security key, etc. The device context may include: the AIoT device's status (registration status, battery level, or activation status), security, capabilities, and NG connection identifiers related to the AIoT device.

[0141] In one possible implementation of this application embodiment, step 401, where the first network element sends a first connection establishment request to the radio access network node, specifically includes:

[0142] A1. If the target AIoT device is a verified device, send the first connection establishment request to the wireless access network node.

[0143] In this embodiment of the application, if the first connection corresponds to a single target AIoT device, the first network element can verify whether the target AIoT device is a legitimate device before sending the first connection establishment request to the wireless access network node. After verifying the legitimacy of the target AIoT device, the first connection can be established for the target AIoT device by sending the first connection establishment request, thereby avoiding the establishment of the corresponding first connection for an invalid target AIoT device and improving the utilization rate of network resources.

[0144] Specifically, after obtaining the identification information of the target AIoT device, the first network element can first request the target device's subscription data from the Unified Data Management (UDM), and then request the Authentication Server Function (AUSF) to complete the identity authentication of the target device based on the identification information of the target device, so as to ensure that the identity of the target device for which the first connection is about to be established is legitimate and valid.

[0145] In one possible implementation of this application embodiment, the first connection establishment request further includes fourth indication information, which is used to indicate the timing of releasing the first connection. In this application embodiment, when the first connection corresponds to a single target AIoT device, the first network element can also determine the timing of releasing the first connection and generate the fourth indication information to indicate the timing of releasing the first connection. Furthermore, the first connection establishment request sent by the first network element to the radio access network may also carry the fourth indication information for indicating the timing of releasing the first connection, enabling the radio access network to determine when to release the first connection, thereby facilitating the maintenance and management of the first connection and reducing its maintenance costs.

[0146] In one possible implementation of this application embodiment, the fourth indication information includes at least one of a first indication sub-information, a second indication sub-information, and a third indication sub-information; the first indication sub-information is used to indicate a release timer, which is used to trigger the radio access network node to release the first connection when it expires; the second indication sub-information is used to indicate a data reporting period or a data reporting count, whereby the data reporting period indicates the period during which the radio access network node receives service data, and the data reporting count indicates the number of times the radio access network node receives service data; the third indication sub-information is used to instruct the radio access network node to maintain the first connection until it receives a release instruction for the first connection.

[0147] In this embodiment of the application, the first network element can specifically indicate the release time of the first connection through three indication sub-information: the first indication sub-information, the second indication sub-information, and the third indication sub-information. This allows the radio access network to determine when to release the first connection, thereby facilitating the maintenance and management of the first connection and reducing the maintenance cost of the first connection.

[0148] Specifically, the first indication sub-information can be used to indicate the release timer. When the radio access network node has no downlink signaling to send to the target AIoT device before the release timer expires, or when the radio access network node has not received uplink data packets from the target AIoT device, the release timer can trigger the radio access network node to initiate a request to release the first connection. It is understood that the release timer can be configured in various ways. For example, different durations of release timers can be configured for different types of AIoT devices, or the duration of the release timer can be set according to information such as the service type and service content of the AIoT service request, or the duration of the release timer can be predetermined without configuration by the first network element. This application embodiment does not limit this.

[0149] The second indication sub-information is used to indicate the data reporting period or the number of data reports. That is, when the AIoT service request is a periodic read command, the first network element can tell the wireless access network node the period and the number of data reports that the wireless access network node may receive. This allows the wireless access network node to ask the first network element whether it needs to release the first connection after the end time of the data reporting period indication or after receiving a specified number of data reports.

[0150] The third instruction sub-information is used to instruct the radio access network node to maintain the first connection until it receives a release instruction for the first connection. That is, the radio access network node can keep the first connection open until it receives a release instruction for the first connection from the first network element, and then release the first connection.

[0151] 402. The wireless access network node receives the first connection establishment request from the first network element.

[0152] The first connection establishment request includes the core network identification information of the first connection allocated by the first network element and the identification information of the first network element. The first connection is used to transmit environmental IoT (AIoT) service signaling or data, and the core network identification information of the first connection is used to identify the first connection.

[0153] In this embodiment, after the first network element sends a first connection establishment request carrying core network identification information of the first connection to the radio access network node, the radio access network node can receive the first connection establishment request so that it can respond to the first connection establishment request sent by the first network element, thereby completing the construction of the connection between the core network element and the radio access network node corresponding to the AIoT device, i.e., the first connection. This enables the implementation of an optimized transmission scheme for the control plane of the AIoT device, reducing the terminal power consumption and network signaling overhead of the AIoT device during communication.

[0154] Understandably, after receiving a first connection request from a first network element, a radio access network node can establish a first connection context to store the information carried in the first connection establishment request. The first connection context may include the core network identification information of the first connection and the identification information of the first network element. If the first connection corresponds to a single target AIoT device, the first connection context may include the core network identification information of the first connection, the identification information of the first network element, the device information of the target AIoT device, and the service type, etc.

[0155] 403. The wireless access network node sends a first connection establishment response to the first network element.

[0156] The first connection establishment response includes the radio access network identification information of the first connection and the identification information of the radio access network node, which are allocated by the radio access network node. The radio access network identification information of the first connection is used to identify the first connection.

[0157] In this embodiment, after receiving a first connection establishment request from a first network element, the radio access network node can determine the identity of the first network element based on the identification information of the first network element in the first connection establishment request, and can store the core network identification information of the first connection in the first connection establishment request. The radio access network node can allocate radio access network identification information for the first connection to be established, and can send the radio access network identification information of the first connection to the first network element through the first connection establishment response, so that the first network element and the radio access network node can respectively store the core network identification information and the radio access network identification information of the first connection, thereby completing the construction of the connection between the core network element and the radio access network node corresponding to the AIoT device, i.e., the first connection, so as to realize the control plane optimized transmission scheme of the AIoT device and reduce the terminal power consumption and network signaling overhead of the AIoT device during communication.

[0158] The first connection establishment response may carry the radio access network (RAN) identification information and the RAN node identification information for the first connection. The core network identification information for the first connection is assigned by the RAN node and is used to identify the first connection; for example, the RAN identification information for the first connection may specifically be the RAN NGAP ID (Radio Access Network Next Generation Access Protocol Area Identity). The RAN node identification information may be information used to identify the RAN node, such as the Global RAN Node ID, RAN Node Name, or RAN ID. Furthermore, the first connection establishment response may also carry the RAN identification information corresponding to the RAN node, such as a Reader ID; this is not limited in this embodiment. Specifically, the first connection establishment response may be an AIOT-NG Setup Response or an Initial device context setup response.

[0159] Understandably, when the first connection corresponds to a single target AIoT device, the radio access network node can first page the target AIoT device using its identification information before sending a first connection establishment response to the first network element. Furthermore, it can determine whether the target AIoT device is within the radio access network node's coverage area and whether it can successfully connect to the radio access network node based on whether a response is received. For target AIoT devices that fail to connect to the radio access network node, the radio access network node can refuse to send a first connection establishment response to the first network element to establish a corresponding first connection for that target AIoT device, thereby avoiding establishing a first connection for invalid target AIoT devices and improving network resource utilization.

[0160] If a radio access network node refuses to establish a first connection for a target AIoT device, it can send a first connection establishment failure response to the first network element. This response may carry the target AIoT device's identification information, the core network identification information of the first connection, and indication information indicating the reason for the failure. The reasons for the failure may include the target AIoT device not being paged, the target AIoT device having low battery, the radio access network node being overloaded, or the radio access network node currently maintaining too many first connections.

[0161] In one possible implementation of this application embodiment, if multiple AIoT devices correspond to the same target coverage area of ​​a wireless access network node, the first connection establishment response further includes first indication information, which is used to indicate the target coverage area of ​​the wireless access network node. In this application embodiment, when the first connection corresponds to multiple AIoT devices, if the multiple AIoT devices corresponding to the first connection correspond to the same target coverage area of ​​a wireless access network node, the first connection establishment response from the wireless access network node may also carry first indication information for indicating the target coverage area of ​​the wireless access network node, enabling the first network element to determine the specific coverage area under which the multiple AIoT devices fall. The target coverage area of ​​the wireless access network node indicated by the first indication information may be less than or equal to the maximum coverage area of ​​the wireless access network node.

[0162] 404. The first network element receives a first connection establishment response from the radio access network node.

[0163] The first connection establishment response includes the radio access network identification information of the first connection and the identification information of the radio access network node, which are allocated by the radio access network node. The radio access network identification information of the first connection is used to identify the first connection.

[0164] In this embodiment, the first network element can receive a first connection establishment response sent by a wireless IoT node. It can also identify the wireless access network node that sent the first connection establishment response by using the identification information of the wireless access network node carried in the response. Furthermore, it can store the wireless access network identification information of the first connection carried in the response. This allows the first network element and the wireless access network node to respectively store the core network identification information and the wireless access network identification information of the first connection. This completes the construction of the connection between the core network element and the wireless access network node, corresponding to the AIoT device—the first connection. This facilitates optimized transmission schemes for the AIoT device's control plane, reducing terminal power consumption and network signaling overhead during communication. It is understood that when the first network element and the wireless access network node respectively store the core network identification information and the wireless access network identification information of the first connection, it can be determined that the first connection has been successfully established.

[0165] As illustrated by the foregoing embodiments, the first network element can send a first connection establishment request carrying core network identification information of the first connection to the radio access network node, and can receive a first connection establishment response carrying radio access network identification information of the first connection from the radio access network node. This allows the first network element and the radio access network node to store the core network identification information and the radio access network identification information of the first connection, respectively. This completes the construction of the connection between the core network element and the radio access network node corresponding to the AIoT device, i.e., the first connection. This enables the implementation of an optimized transmission scheme for the control plane of the AIoT device, reducing the terminal power consumption and network signaling overhead of the AIoT device during communication.

[0166] Please refer to Figure 5. Figure 5 shows a schematic diagram of a second interaction process between the first network element and the wireless access network node provided in an embodiment of this application. A communication method provided in an embodiment of this application mainly includes the following steps:

[0167] 501. The first network element sends a first connection establishment request to the wireless access network node.

[0168] 502. The wireless access network node receives the first connection establishment request from the first network element.

[0169] 503. The wireless access network node sends a first connection establishment response to the first network element.

[0170] 504. The first network element receives the first connection establishment response from the radio access network node.

[0171] The content of steps 501-504 above is similar to that of steps 401-404 above, and will not be repeated here in the embodiments of this application.

[0172] 505. The first network element sends a first AIoT service request to the wireless access network node based on the first connection.

[0173] The first AIoT service request includes the core network identification information of the first connection, the radio access network identification information of the first connection, the first task identification information, and the device information of the target AIoT device.

[0174] In this embodiment, after establishing the first connection (corresponding to the AIoT device) between the core network element and the radio access network node, the first network element can send a first AIoT service request to the radio access network node based on the established first connection to transmit service data related to the AIoT device. This facilitates the implementation of an optimized transmission scheme for the AIoT device's control plane, reducing terminal power consumption and network signaling overhead during communication. The first task identifier information can be used to identify the first AIoT service request, represented by a first Task ID. The service type of the first AIoT service request can be disk storage, command, or disk storage + command, and it can be a service request related to the target AIoT device. The first AIoT service request may also carry first service content, area information, etc., where the first service content can be encapsulated in a protocol layer data packet and is invisible to the radio access network node. When the first connection corresponds to multiple AIoT devices, the target AIoT device can be one or more of the multiple AIoT devices; when the first connection corresponds to a single target AIoT device, the target AIoT device is the AIoT device corresponding to the first connection. The device information of the target AIoT device may include the identification information of the target AIoT device, the identification information of the device group to which the target AIoT device belongs, and device filtering criteria, etc.

[0175] It is understandable that the first connection established between the first network element and the radio access network node can be a first connection corresponding to multiple AIoT devices or a first connection corresponding to a single target AIoT device. The device information of the target AIoT device carried in the first AIoT service request can be the device information of one or more AIoT devices among multiple AIoT devices, or it can be the device information of a single target AIoT device. After receiving the first service request, the first network element can generate first task identification information for the first service request and put the first task identification information into the first service request. Then, based on the established first connection corresponding to the target AIoT device, the first AIoT service request can be sent to the radio access network node, so that the radio access network node can process the service content corresponding to the first AIoT service request.

[0176] It should be noted that when the first connection corresponds to multiple AIoT devices, the first network element may send the first AIoT service request to the radio access network node based on the first connection without carrying the device information of the target AIoT device. Instead, it may carry the identification information of the application function corresponding to the multiple AIoT devices, i.e., AF ID, or the identification information of the service request corresponding to the multiple AIoT devices, i.e., Service ID, etc.

[0177] 506. The wireless access network node receives the first AIoT service request from the first network element based on the first connection.

[0178] The first AIoT service request includes the core network identification information of the first connection, the radio access network identification information of the first connection, the first task identification information, and the device information of the target AIoT device.

[0179] In this embodiment of the application, the wireless access network node can receive the first AIoT service request sent by the first network element based on the first connection constructed corresponding to the target AIoT device, so that the wireless access network node can process the service content corresponding to the first AIoT service request based on the first AIoT service request.

[0180] 507. The wireless access network node sends the first AIoT service response to the first network element based on the first connection.

[0181] The first AIoT service response includes the core network identification information of the first connection, the radio access network identification information of the first connection, the first task identification information, the device information of the target AIoT device, and the first service data.

[0182] In this embodiment, after receiving a first AIoT service request based on a first connection, the wireless access network node can parse the first AIoT service request to extract information including the core network identifier information of the first connection, the wireless access network identifier information of the first connection, the first task identifier information, and the device information of the target AIoT device. Specifically, the wireless access network node can bind the first task identifier information with the core network identifier information and the wireless access network identifier information of the first connection.

[0183] Understandably, after receiving a first AIoT service request, a radio access network (RAN) node can send the first service content from the first AIoT service request to the target AIoT device and receive a service response from the target AIoT device. The service response may include first service data corresponding to the first service content. This first service data can be in Protocol Data Unit (PDU) format. Upon receiving a response from the target AIoT device, the RAN node can instruct the first AIoT service response to carry the first service data and send it to the first network element based on the first connection. This enables the transmission of service data related to the target AIoT device based on the first connection, facilitating an optimized transmission scheme for the AIoT device's control plane and reducing terminal power consumption and network signaling overhead during communication.

[0184] 508. The first network element receives the first AIoT service response from the wireless access network node based on the first connection.

[0185] The first AIoT service response includes the core network identification information of the first connection, the radio access network identification information of the first connection, the first task identification information, the device information of the target AIoT device, and the first service data.

[0186] In this embodiment, the first network element can receive a first AIoT service response from a wireless access network node based on a first connection, and can parse the first service data from the first AIoT service response, thereby enabling the transmission of service data related to the target AIoT device based on the first connection. This facilitates the implementation of an optimized transmission scheme for the control plane of the AIoT device, reducing the terminal power consumption and network signaling overhead of the AIoT device during communication.

[0187] In one possible implementation of this application embodiment, after step 508 where the first network element receives the first AIoT service response from the radio access network node based on the first connection, the method may further include:

[0188] B1. The first network element sends the second instruction information to the wireless access network based on the first connection.

[0189] The second instruction information is used to instruct the wireless access network node to unbind the first task identification information from the first connection.

[0190] In this embodiment, after the first network element completes the service related to the first AIoT service request based on the first connection, it can send a second indication information based on the first connection to instruct the wireless access network to release the binding relationship between the first task identifier information in the first AIoT service request and the first connection, so that the first connection can be used for the transmission of more data related to other AIoT services, thereby reducing the terminal power consumption and network signaling overhead of AIoT devices during communication.

[0191] B2. The wireless access network node receives second indication information from the first network element based on the first connection.

[0192] In this embodiment of the application, after receiving the second indication information, the wireless access network node can unbind the first task identifier information in the first AIoT service request from the first connection, so that the first connection can be used for the transmission of more data related to other AIoT services, thereby reducing the terminal power consumption and network signaling overhead of AIoT devices during communication.

[0193] As illustrated by the foregoing embodiments, the first network element can send a first connection establishment request carrying core network identification information of the first connection to the radio access network node, and can receive a first connection establishment response carrying radio access network identification information of the first connection from the radio access network node. This allows the first network element and the radio access network node to store the core network identification information and the radio access network identification information of the first connection, respectively. This completes the construction of the connection between the core network element and the radio access network node corresponding to the AIoT device, i.e., the first connection. Furthermore, it enables the transmission of service data related to the target AIoT device based on the first connection, thereby enabling the optimization of the control plane transmission scheme of the AIoT device and reducing the terminal power consumption and network signaling overhead of the AIoT device during communication.

[0194] Please refer to Figure 6. Figure 6 shows a schematic diagram of a third interaction process between the first network element and the wireless access network node provided in an embodiment of this application. A communication method provided in an embodiment of this application mainly includes the following steps:

[0195] 601. The first network element sends a second AIoT service request to the wireless access network node.

[0196] The second AIoT service request includes a first protocol layer data packet and second task identification information. The first protocol layer data packet encapsulates the identification information of the target AIoT device.

[0197] In this embodiment, before establishing the first connection, the first network element can establish a node-level connection with the wireless access network and can send a second AIoT service request carrying a first protocol layer data packet and second task identification information to the wireless access network node through the node-level connection. The first protocol layer data packet can encapsulate the identification information of the target AIoT device. Since the identification information of the target AIoT device is encapsulated in the first protocol layer data packet, it is invisible to the wireless access network node. Specifically, the first protocol layer data packet can be a Non-Access Stratum (NAS) layer data packet. The second AIoT service request can also carry second service content, area information, etc., wherein the second service content can be encapsulated in the first protocol layer data packet and is invisible to the wireless access network node. The second task identification information can be information used to identify the second AIoT service request and can be represented by a second Task ID.

[0198] It should be noted that the service type of the second AIoT service request can be inventory + command, meaning the first network element can send the second AIoT service request to the radio access network node in scenarios where multiple service requests are continuously issued. The first network element can also send the second AIoT service request to the radio access network node in periodic data reporting scenarios. Periodic data reporting scenarios refer to situations where the current AIoT service has not yet been completed, but subsequent data related to that service still needs to go through the previously established first connection.

[0199] 602. The wireless access network node receives the second AIoT service request from the first network element.

[0200] The second AIoT service request includes a first protocol layer data packet and second task identification information. The first protocol layer data packet encapsulates the identification information of the target AIoT device.

[0201] In this embodiment, before the first connection is established, the wireless access network node can receive a second AIoT service request carrying a first protocol layer data packet and second task identification information through a node-level connection with the first network element. Since the identification information of the target AIoT device is encapsulated in the first protocol layer data packet, the identification information of the target AIoT device is invisible to the wireless access network node.

[0202] 603. The wireless access network node sends the second AIoT service response to the first network element.

[0203] The second AIoT service response includes second task identification information, third instruction information, and second service data. The third instruction information is used to instruct the first network element to establish a first connection, and the second service data includes the identification information of the target AIoT device.

[0204] In this implementation, after receiving a second AIoT service request from a first network element, the wireless access network node can send the first protocol layer data packet from the second AIoT service request to the target AIoT device and receive the second service data returned by the target AIoT device. It is understood that since the identification information of the target AIoT device is not visible to the wireless access network node at this time, the wireless access network node can obtain the identification information of the target AIoT device through other means. For example, it can obtain the class identification information of the target AIoT device, such as the Access Layer System Identifier (AS ID), or it can request the identification information of the target AIoT device from the first network element.

[0205] After obtaining the identification information of the target AIoT device, the wireless access network node can determine whether a first connection corresponding to the target AIoT device has been established between it and the first network element. If the wireless access network node determines that no first connection has been established between it and the first network element, it can generate third indication information to instruct the first network element to establish the first connection, and send the third indication information to the first network element through the second AIoT service response, so that the first network element can trigger the establishment process of the first connection.

[0206] 604. The first network element receives the second AIoT service response from the wireless access network node.

[0207] The second AIoT service response includes second task identification information, third instruction information, and second service data. The third instruction information is used to instruct the first network element to establish a first connection, and the second service data includes the identification information of the target AIoT device.

[0208] In this embodiment, the first network element can receive a second AIoT service response from a wireless access network node, and can parse the second task identification information, the third indication information, and the second service data from the second AIoT service response. Furthermore, the first network element can trigger the subsequent establishment process of the first connection under the instruction of the third indication information.

[0209] 605. The first network element sends a first connection establishment request to the wireless access network node.

[0210] 606. The wireless access network node receives the first connection establishment request from the first network element.

[0211] 607. The wireless access network node sends a first connection establishment response to the first network element.

[0212] 608. The first network element receives the first connection establishment response from the radio access network node.

[0213] The content of steps 605-608 above is similar to that of steps 401-404 above, and will not be repeated here in the embodiments of this application.

[0214] As illustrated by the foregoing embodiments, before the first network element sends a first connection establishment request to the wireless access network node to establish the first connection corresponding to the target AIoT device, the wireless access network node can obtain a first protocol layer data packet encapsulating the identification information of the target AIoT device based on the second AIoT service request sent by the IoT network element. When it is determined that the target AIoT device has not yet established the corresponding first connection, the wireless access network node sends the identification information of the target AIoT device and a third indication message instructing the first network element to establish the first connection based on the second AIoT service response. This enables the first network element to obtain the identification information of the target AIoT device based on the second AIoT service response to establish the first connection corresponding to the target AIoT device.

[0215] Furthermore, the first network element can send a first connection establishment request carrying the core network identifier information of the first connection to the radio access network node, and can receive a first connection establishment response carrying the radio access network identifier information of the first connection from the radio access network node. This allows the first network element and the radio access network node to store the core network identifier information and the radio access network identifier information of the first connection, respectively. This completes the construction of the connection between the core network element and the radio access network node corresponding to the AIoT device, i.e., the first connection. This enables the implementation of an optimized transmission scheme for the control plane of the AIoT device, reducing the terminal power consumption and network signaling overhead of the AIoT device during communication.

[0216] Please refer to Figure 7, which illustrates a fourth interaction process between the first network element and the wireless access network node provided in an embodiment of this application. The communication method provided in this embodiment mainly includes the following steps:

[0217] 701. The wireless access network node sends a first connection establishment request to the first network element.

[0218] The first connection establishment request includes the radio access network identification information and the radio access network identification information of the first connection allocated by the radio access network node. The first connection is used to transmit environmental Internet of Things (AIoT) service signaling or data, and the radio access network identification information of the first connection is used to identify the first connection.

[0219] In this embodiment, a wireless access network node can trigger the establishment of a first connection by sending a first connection establishment request to a first network element. The first connection can be a connection between the first network element and the wireless access network node corresponding to an AIoT device in the environment; that is, the first connection can be used to transmit service signaling or data related to the AIoT device, such as IP data or non-IP data, between the first network element and the wireless access network node. Specifically, the first connection can be described as an AIoT-NG connection or an NG-like connection. The first connection establishment request can specifically be an AIOT-NG Setup Request or an Initial device context setup request.

[0220] The first connection establishment request may carry the radio access network (RAN) identification information and the RAN node identification information for the first connection. The core network identification information for the first connection is assigned by the RAN node and is used to identify the first connection; for example, the RAN identification information for the first connection may specifically be the RAN NGAP ID. The RAN node identification information may be information used to identify the RAN node's identity, such as the Global RAN Node ID, RAN Node Name, or RAN ID. Furthermore, the first connection establishment response may also carry the RAN identification information corresponding to the RAN node, such as a Reader ID; however, this embodiment does not limit this to specific cases.

[0221] Understandably, a wireless access network (WLAN) node, after determining that no first connection corresponding to the AIoT device has been established with the first network element, can trigger the establishment of the first connection by sending a first connection establishment request carrying the WLAN identification information of the first connection to the first network element. For example, when the WLAN node starts up, it can first perform self-testing and configuration to ensure that the hardware and software are running normally. Since the WLAN node has just started up, it can assume that no first connection has been established with the first network element. At this time, the WLAN node can assign WLAN identification information to the AIoT device to identify the corresponding first connection, and send the WLAN identification information of the first connection to the first network element through the first connection establishment request, so as to establish the first connection corresponding to the AIoT device.

[0222] In one possible implementation of this application embodiment, the first connection corresponds to multiple AIoT devices. In this embodiment, the first connection established between the first network element and the radio access network node can correspond to multiple AIoT devices; that is, the first connection can be a connection shared by multiple AIoT devices. Specifically, the radio access network node can assign the same radio access network identifier information for the first connection to multiple AIoT devices and trigger the establishment of a first connection shared by multiple AIoT devices through a first connection establishment request. By establishing a first connection shared by multiple AIoT devices, the number of connections established for each AIoT device can be greatly reduced, thereby reducing the maintenance cost of the first connection and effectively improving the utilization rate of network resources. It is understood that the advantage of establishing a first connection shared by multiple AIoT devices is that the number of connections established is small, the maintenance cost is low, the utilization rate of network resources can be effectively improved, and the network latency caused by frequent link breaking and establishment is reduced.

[0223] In one possible implementation of this application embodiment, the relationship between the plurality of AIoT devices satisfies at least one of the following: the plurality of AIoT devices correspond to the target coverage area of ​​the same wireless access network node; the plurality of AIoT devices correspond to the same service request; the plurality of AIoT devices correspond to the same application function; the plurality of AIoT devices correspond to the same service type.

[0224] In this embodiment, when the first connection corresponds to multiple AIoT devices, these multiple AIoT devices can be AIoT devices within the target coverage area of ​​the same radio access network node, AIoT devices corresponding to the same service request, AIoT devices corresponding to the same application function, or AIoT devices corresponding to the same service type. That is, a first connection can be established for multiple associated AIoT devices to share, thereby reducing the maintenance cost of the first connection and effectively improving the utilization of network resources. It is understood that a radio access network node can construct a first connection shared by multiple AIoT devices within the target coverage area of ​​the same radio access network node, or it can construct a first connection shared by multiple AIoT devices for a single service request, or it can construct a first connection shared by multiple AIoT devices for a single application function, or it can construct a first connection shared by multiple AIoT devices for the same service type.

[0225] In one possible implementation of this application embodiment, if multiple AIoT devices correspond to the same target coverage area of ​​a wireless access network node, the first connection establishment request further includes first indication information, which is used to indicate the target coverage area of ​​the wireless access network node. In this embodiment, if the multiple AIoT devices corresponding to the first connection correspond to the same target coverage area of ​​a wireless access network node, the first connection establishment request of the wireless access network node may also carry first indication information indicating the target coverage area of ​​the wireless access network node, enabling the first network element to determine the specific coverage area under which the multiple AIoT devices fall. The target coverage area of ​​the wireless access network node indicated by the first indication information may be less than or equal to the maximum coverage area of ​​the wireless access network node.

[0226] In one possible implementation of this application embodiment, the first connection corresponds to a single target AIoT device, and the first connection establishment request further includes the identification information of the target AIoT device. In this application embodiment, the first connection established between the first network element and the radio access network node can correspond to a single target AIoT device; that is, the first connection can be a connection unique to a single target AIoT device, used only for transmitting AIoT service data related to the target AIoT device. This improves the security of AIoT service data and facilitates independent management of the connection corresponding to each AIoT device. It is understood that when the radio access network node triggers the establishment of a first connection corresponding to a single target AIoT device, the first connection establishment request sent by the radio access network node to the first network element can also carry the identification information of the target AIoT device, so that the first network element can determine which specific target AIoT device the first connection corresponds to. The identification information of the target AIoT device can be, for example, a Device ID. It is understood that the radio access network node can obtain the identification information of the target AIoT device based on the received AIoT service request or AIoT service response.

[0227] In one possible implementation of this application embodiment, the first connection establishment request further includes at least one of the target AIoT device's device information and service type. In this application embodiment, if the first connection corresponds to a single target AIoT device, the first connection establishment request sent by the radio access network node to the first network element may also carry at least one of the target AIoT device's device information and service type, enabling the first network element to establish a device context based on the target AIoT device's device information, and to determine the service type of the service data to be carried by the first connection after its establishment. The service type can be disk storage, command, or disk storage + command. The target AIoT device's device information may include the AF information to which the device belongs, such as AF ID, device type, device security capabilities, security key, etc. The device context may include: the AIoT device's status (registration status, battery level, or activation status), security, capabilities, and NG connection identifiers related to the AIoT device, etc.

[0228] 702. The first network element receives the first connection establishment request from the radio access network node.

[0229] The first connection establishment request includes the radio access network identification information and the radio access network identification information of the first connection allocated by the radio access network node. The first connection is used to transmit environmental Internet of Things (AIoT) service signaling or data, and the radio access network identification information of the first connection is used to identify the first connection.

[0230] In this embodiment, after the radio access network node sends a first connection establishment request carrying radio access network identifier information of the first connection to the first network element, the first network element can receive the first connection establishment request so as to respond to the first connection establishment request sent by the radio access network node, thereby completing the construction of the connection between the core network element and the radio access network node corresponding to the AIoT device, i.e., the first connection, so as to realize the control plane optimized transmission scheme of the AIoT device and reduce the terminal power consumption and network signaling overhead of the AIoT device during communication.

[0231] It is understandable that after receiving a first connection request from another network element, the first network element can establish a first connection context to store the information carried in the first connection establishment request. The first connection context may include the radio access network (RAN) identification information and the RAN identification information of the first connection. If the first connection corresponds to a single target AIoT device, the first connection context may include the RAN identification information and the RAN identification information of the first connection, the device information of the target AIoT device, and the service type, etc.

[0232] 703. The first network element sends a first connection establishment response to the radio access network node.

[0233] The first connection establishment response includes the core network identification information of the first connection allocated by the first network element and the identification information of the first network element. The core network identification information of the first connection is used to identify the first connection.

[0234] In this embodiment, after receiving a first connection establishment request from a radio access network node, the first network element can determine the identity of the radio access network node based on the identification information of the radio access network node in the first connection establishment request, and can store the radio access network identification information of the first connection in the first connection establishment request. The first network element can allocate core network identification information for the first connection to be established, and can send the core network identification information of the first connection to the radio access network node through the first connection establishment response, so that the first network element and the radio access network node can respectively store the core network identification information and the radio access network identification information of the first connection, thereby completing the construction of the connection between the core network element and the radio access network node corresponding to the AIoT device, i.e., the first connection, so as to realize the control plane optimized transmission scheme of the AIoT device and reduce the terminal power consumption and network signaling overhead of the AIoT device during communication.

[0235] The first connection establishment response may carry core network identification information and identification information of the first network element. The core network identification information of the first connection is pre-assigned by the first network element and is used to identify the first connection; for example, the core network identification information of the first connection may be a CN NGAP ID. The identification information of the first network element may be information used to identify the identity of the first network element, such as an AIOT NF ID or AIOT NF Name. Furthermore, the first connection establishment response may also carry a list of public terrestrial mobile networks supported by the first network element, etc., but this embodiment of the application does not limit this.

[0236] In one possible implementation of this application embodiment, step 703, in which the first network element sends a first connection establishment response to the radio access network node, specifically includes:

[0237] C1. If the target AIoT device is a verified device, send a first connection establishment response to the wireless access network node.

[0238] In this embodiment of the application, if the first connection corresponds to a single target AIoT device, the first network element can verify whether the target AIoT device is a legitimate device before sending the first connection establishment response to the wireless access network node. After verifying the legitimacy of the target AIoT device, the first network element can then establish the corresponding first connection for the target AIoT device by sending the first connection establishment response, thereby avoiding the establishment of the corresponding first connection for an invalid target AIoT device and improving the utilization rate of network resources.

[0239] Specifically, after obtaining the identification information of the target AIoT device, the first network element can first request the target device's subscription data from the unified data management system, and then request the authentication server function to complete the identity authentication of the target device based on the identification information of the target device, so as to ensure that the identity of the target device for which the first connection is about to be established is legitimate and valid.

[0240] Understandably, when the first connection corresponds to a single target AIoT device, if the first network element refuses to establish the first connection for the target AIoT device, it can send a first connection establishment failure response to the radio access network node. This response may carry the target AIoT device's identification information, the core network identification information of the first connection, and indication information indicating the reason for the connection establishment failure. The reason for the failure may include the target AIoT device being an unauthorized device, or the target AIoT device not being in a PLMN supported by the first network element, etc.

[0241] In one possible implementation of this application embodiment, the first connection establishment response further includes fourth indication information, which is used to indicate the timing of releasing the first connection. In this application embodiment, when the first connection corresponds to a single target AIoT device, the first network element can also determine the timing of releasing the first connection and generate the fourth indication information to indicate the timing of releasing the first connection. Furthermore, the first connection establishment response sent by the first network element to the radio access network can also carry the fourth indication information for indicating the timing of releasing the first connection, enabling the radio access network to determine when to release the first connection, thereby facilitating the maintenance and management of the first connection and reducing its maintenance costs.

[0242] In one possible implementation of this application embodiment, the fourth indication information includes at least one of a first indication sub-information, a second indication sub-information, and a third indication sub-information; the first indication sub-information is used to indicate a release timer, which is used to trigger the radio access network node to release the first connection when it expires; the second indication sub-information is used to indicate a data reporting period or a data reporting count, whereby the data reporting period indicates the period during which the radio access network node receives service data, and the data reporting count indicates the number of times the radio access network node receives service data; the third indication sub-information is used to instruct the radio access network node to maintain the first connection until it receives a release instruction for the first connection.

[0243] In this embodiment of the application, the first network element can specifically indicate the release time of the first connection through three indication sub-information: the first indication sub-information, the second indication sub-information, and the third indication sub-information. This allows the radio access network to determine when to release the first connection, thereby facilitating the maintenance and management of the first connection and reducing the maintenance cost of the first connection.

[0244] Specifically, the first indication sub-information can be used to indicate the release timer. When the radio access network node has no downlink signaling to send to the target AIoT device before the release timer expires, or when the radio access network node has not received uplink data packets from the target AIoT device, the release timer can trigger the radio access network node to initiate a request to release the first connection. It is understood that the release timer can be configured in various ways. For example, different durations of release timers can be configured for different types of AIoT devices, or the duration of the release timer can be set according to information such as the service type and service content of the AIoT service request, or the duration of the release timer can be predetermined without configuration by the first network element. This application embodiment does not limit this.

[0245] The second indication sub-information is used to indicate the data reporting period or the number of data reports. That is, when the AIoT service request is a periodic read command, the first network element can tell the wireless access network node the period and the number of data reports that the wireless access network node may receive. This allows the wireless access network node to ask the first network element whether it needs to release the first connection after the end time of the data reporting period indication or after receiving a specified number of data reports.

[0246] The third instruction sub-information is used to instruct the radio access network node to maintain the first connection until it receives a release instruction for the first connection. That is, the radio access network node can keep the first connection open until it receives a release instruction for the first connection from the first network element, and then release the first connection.

[0247] 704. The wireless access network node receives the first connection establishment response from the first network element.

[0248] The first connection establishment response includes the core network identification information of the first connection allocated by the first network element and the identification information of the first network element. The core network identification information of the first connection is used to identify the first connection.

[0249] In this embodiment, the wireless access network node can receive a first connection establishment response sent by a first network element. It can also identify the first network element sending the first connection establishment response by using the identification information of the first network element carried in the response. Furthermore, it can store the core network identification information of the first connection carried in the response. This allows the first network element and the wireless access network node to respectively store the core network identification information and the wireless access network identification information of the first connection, thereby completing the construction of the connection between the core network element and the wireless access network node corresponding to the AIoT device—the first connection. This facilitates the implementation of an optimized transmission scheme for the AIoT device's control plane, reducing terminal power consumption and network signaling overhead during communication. It is understood that when the first network element and the wireless access network node respectively store the core network identification information and the wireless access network identification information of the first connection, it can be determined that the first connection has been successfully established.

[0250] As illustrated by the foregoing embodiments, a wireless access network node can send a first connection establishment request carrying wireless access network identification information of the first connection to a first network element node, and can receive a first connection establishment response carrying core network identification information of the first connection from an IoT network element. This allows the first network element and the wireless access network node to store the core network identification information and the wireless access network identification information of the first connection, respectively. This completes the construction of the connection between the core network element and the wireless access network node corresponding to the AIoT device, i.e., the first connection. This enables the implementation of an optimized transmission scheme for the control plane of the AIoT device, reducing the terminal power consumption and network signaling overhead of the AIoT device during communication.

[0251] Please refer to Figure 8, which illustrates a fifth interaction process between the first network element and the wireless access network node provided in an embodiment of this application. The communication method provided in this embodiment mainly includes the following steps:

[0252] 801. The wireless access network node sends a first connection establishment request to the first network element.

[0253] 802. The first network element receives the first connection establishment request from the radio access network node.

[0254] 803. The first network element sends a first connection establishment response to the wireless access network node.

[0255] 804. The wireless access network node receives a first connection establishment response from the first network element.

[0256] The content of steps 801-804 above is similar to that of steps 701-704 above, and will not be repeated here in the embodiments of this application.

[0257] 805. The first network element sends a first AIoT service request to the wireless access network node based on the first connection.

[0258] The first AIoT service request includes the core network identification information of the first connection, the radio access network identification information of the first connection, the first task identification information, and the device information of the target AIoT device.

[0259] In this embodiment, after establishing the first connection (corresponding to the AIoT device) between the core network element and the radio access network node, the first network element can send a first AIoT service request to the radio access network node based on the established first connection to transmit service data related to the AIoT device. This facilitates the implementation of an optimized transmission scheme for the AIoT device's control plane, reducing terminal power consumption and network signaling overhead during communication. The first task identifier information can be used to identify the first AIoT service request, represented by a first Task ID. The service type of the first AIoT service request can be disk storage, command, or disk storage + command, and it can be a service request related to the target AIoT device. The first AIoT service request may also carry first service content, area information, etc., where the first service content can be encapsulated in a protocol layer data packet and is invisible to the radio access network node. When the first connection corresponds to multiple AIoT devices, the target AIoT device can be one or more of the multiple AIoT devices; when the first connection corresponds to a single target AIoT device, the target AIoT device is the AIoT device corresponding to the first connection. The device information of the target AIoT device may include the identification information of the target AIoT device, the identification information of the device group to which the target AIoT device belongs, and device filtering criteria, etc.

[0260] It is understandable that the first connection established between the first network element and the radio access network node can be a first connection corresponding to multiple AIoT devices or a first connection corresponding to a single target AIoT device. The device information of the target AIoT device carried in the first AIoT service request can be the device information of one or more AIoT devices among multiple AIoT devices, or it can be the device information of a single target AIoT device. After receiving the first service request, the first network element can generate first task identification information for the first service request and put the first task identification information into the first service request. Then, based on the established first connection corresponding to the target AIoT device, the first AIoT service request can be sent to the radio access network node, so that the radio access network node can process the service content corresponding to the first AIoT service request.

[0261] It should be noted that when the first connection corresponds to multiple AIoT devices, the first network element may send the first AIoT service request to the radio access network node based on the first connection without carrying the device information of the target AIoT device. Instead, it may carry the identification information of the application function corresponding to the multiple AIoT devices, i.e., AF ID, or the identification information of the service request corresponding to the multiple AIoT devices, i.e., Service ID, etc.

[0262] 806. The wireless access network node receives the first AIoT service request from the first network element based on the first connection.

[0263] The first AIoT service request includes the core network identification information of the first connection, the radio access network identification information of the first connection, the first task identification information, and the device information of the target AIoT device.

[0264] In this embodiment of the application, the wireless access network node can receive the first AIoT service request sent by the first network element based on the first connection constructed corresponding to the target AIoT device, so that the wireless access network node can process the service content corresponding to the first AIoT service request based on the first AIoT service request.

[0265] 807. The wireless access network node sends the first AIoT service response to the first network element based on the first connection.

[0266] The first AIoT service response includes the core network identification information of the first connection, the radio access network identification information of the first connection, the first task identification information, the device information of the target AIoT device, and the first service data.

[0267] In this embodiment, after receiving a first AIoT service request based on a first connection, the wireless access network node can parse the first AIoT service request to extract information including the core network identifier information of the first connection, the wireless access network identifier information of the first connection, the first task identifier information, and the device information of the target AIoT device. Specifically, the wireless access network node can bind the first task identifier information with the core network identifier information and the wireless access network identifier information of the first connection.

[0268] Understandably, after receiving a first AIoT service request, a radio access network (RAN) node can send the first service content from the first AIoT service request to the target AIoT device and receive a service response from the target AIoT device. The service response may include first service data corresponding to the first service content. This first service data can be in Protocol Data Unit (PDU) format. Upon receiving a response from the target AIoT device, the RAN node can instruct the first AIoT service response to carry the first service data and send it to the first network element based on the first connection. This enables the transmission of service data related to the target AIoT device based on the first connection, facilitating an optimized transmission scheme for the AIoT device's control plane and reducing terminal power consumption and network signaling overhead during communication.

[0269] 808. The first network element receives the first AIoT service response from the wireless access network node based on the first connection.

[0270] The first AIoT service response includes the core network identification information of the first connection, the radio access network identification information of the first connection, the first task identification information, the device information of the target AIoT device, and the first service data.

[0271] In this embodiment, the first network element can receive a first AIoT service response from a wireless access network node based on a first connection, and can parse the first service data from the first AIoT service response, thereby enabling the transmission of service data related to the target AIoT device based on the first connection. This facilitates the implementation of an optimized transmission scheme for the control plane of the AIoT device, reducing the terminal power consumption and network signaling overhead of the AIoT device during communication.

[0272] In one possible implementation of this application embodiment, after step 508 where the first network element receives the first AIoT service response from the radio access network node based on the first connection, the method may further include:

[0273] D1. The first network element sends the second instruction information to the wireless access network based on the first connection.

[0274] The second instruction information is used to instruct the wireless access network node to unbind the first task identification information from the first connection.

[0275] In this embodiment, after the first network element completes the service related to the first AIoT service request based on the first connection, it can send a second indication information based on the first connection to instruct the wireless access network to release the binding relationship between the first task identifier information in the first AIoT service request and the first connection, so that the first connection can be used for the transmission of more data related to other AIoT services, thereby reducing the terminal power consumption and network signaling overhead of AIoT devices during communication.

[0276] D2. The wireless access network node receives second indication information from the first network element based on the first connection.

[0277] In this embodiment of the application, after receiving the second indication information, the wireless access network node can unbind the first task identifier information in the first AIoT service request from the first connection, so that the first connection can be used for the transmission of more data related to other AIoT services, thereby reducing the terminal power consumption and network signaling overhead of AIoT devices during communication.

[0278] As illustrated by the foregoing embodiments, the first network element can send a first connection establishment request carrying core network identification information of the first connection to the radio access network node, and can receive a first connection establishment response carrying radio access network identification information of the first connection from the radio access network node. This allows the first network element and the radio access network node to respectively store the core network identification information and the radio access network identification information of the first connection, thereby completing the construction of the connection between the core network element and the radio access network node corresponding to the AIoT device—that is, the first connection. Furthermore, it enables the transmission of service data related to the target AIoT device based on the first connection, facilitating the optimization of the AIoT device's control plane transmission scheme and reducing terminal power consumption and network signaling overhead during communication.

[0279] Please refer to Figure 9, which illustrates the sixth interaction process between the first network element and the wireless access network node provided in this embodiment of the application. The communication method provided in this embodiment mainly includes the following steps:

[0280] 901. The wireless access network node receives the second AIoT service response from the target AIoT device.

[0281] The second AIoT service response includes the identification information of the target AIoT device and the second service data.

[0282] In this embodiment, before establishing the first connection, the first network element can establish a node-level connection with the radio access network and send a second AIoT service request to the radio access network node through the node-level connection. The second AIoT service request may carry second service content corresponding to the second AIoT service request and the identification information of the target AIoT device. After receiving the second AIoT service request sent by the first network element based on the node-level connection, the radio access network node can forward the second AIoT service request to the target AIoT device. It can also receive a second AIoT service response returned by the target AIoT device, which may carry the identification information of the target AIoT device and second service data corresponding to the second service content.

[0283] It is understandable that after parsing the identification information of the target AIoT device from the second AIoT service response, the wireless access network node can determine whether a first connection corresponding to the target AIoT device has been established between itself and the first network element based on the identification information of the target AIoT device. If the wireless access network node determines that a first connection corresponding to the target AIoT device has not been established, it can trigger the subsequent first connection establishment process.

[0284] 902. The wireless access network node sends a first connection establishment request to the first network element.

[0285] 903. The first network element receives the first connection establishment request from the radio access network node.

[0286] 904. The first network element sends a first connection establishment response to the radio access network node.

[0287] 905. The wireless access network node receives a first connection establishment response from the first network element.

[0288] The content of steps 902-905 above is similar to that of steps 701-704 above, and will not be repeated here in the embodiments of this application.

[0289] 906. The wireless access network node sends the second AIoT service response to the first network element based on the first connection.

[0290] The second AIoT service response includes the identification information of the target AIoT device and the second service data.

[0291] In this embodiment of the application, after the establishment of the connection between the core network element and the wireless access network node corresponding to the AIoT device, i.e. the first connection, is completed, the wireless access network node can send a second AIoT service response to the first network element based on the established first connection to realize the transmission of AIoT device-related service data based on the first connection, so as to realize the control plane optimized transmission scheme of AIoT device and reduce the terminal power consumption and network signaling overhead of AIoT device during communication.

[0292] As illustrated by the foregoing embodiments, before establishing the first connection corresponding to the target AIoT device by sending a first connection establishment request to the first network element, the wireless access network node can send a second AIoT service request to the target device and obtain the identification information of the target AIoT device from the second AIoT service response returned by the target device. This allows it to establish the first connection corresponding to the target AIoT device by sending the first connection establishment request to the first network element. Furthermore, the first network element can send a first connection establishment request carrying the core network identification information of the first connection to the wireless access network node and receive a first connection establishment response carrying the wireless access network identification information of the first connection from the wireless access network node. This enables the first network element and the wireless access network node to store the core network identification information and the wireless access network identification information of the first connection, respectively. This completes the construction of the connection between the core network element and the wireless access network node corresponding to the AIoT device, i.e., the first connection. This allows for optimized transmission schemes for the control plane of the AIoT device, reducing terminal power consumption and network signaling overhead during communication.

[0316] As illustrated by the foregoing embodiments, the first network element can send a first connection establishment request carrying core network identification information of the first connection to the radio access network node, and can receive a first connection establishment response carrying radio access network identification information of the first connection from the radio access network node. This allows the first network element and the radio access network node to store the core network identification information and the radio access network identification information of the first connection, respectively. This completes the construction of the connection between the core network element and the radio access network node corresponding to the AIoT device, i.e., the first connection. This enables the implementation of an optimized transmission scheme for the control plane of the AIoT device, reducing the terminal power consumption and network signaling overhead of the AIoT device during communication.

[0317] Figure 11 is a schematic diagram of a communication device provided in an embodiment of this application. The communication device can specifically be a wireless access network node, and the communication device specifically includes:

[0318] The receiving module 1101 is used to receive a first connection establishment request from a first network element.
