[0005] To this end, the following technical solutions are adopted in the embodiments of the present application:

[0006] In the first aspect, an identification method is provided in an embodiment of the present application, which is executed by a network device, and the method includes: sending service configuration information; the service configuration information includes configuration parameters that support the target service itself; receiving interest information of a target terminal device; the target terminal device refers to a terminal device that needs one or more target services supported by the network device, and the interest information indicates that the target terminal device needs one or more target services supported by the network device.

[0016] In this embodiment, after receiving the service configuration information, the terminal device can determine whether it needs the target service of the network device based on its own needs.

[0054] Figure 1 is a schematic diagram of an application scenario of a wireless communication system provided in an embodiment of the present application. As shown in Figure 1 , the wireless communication system 100 may include at least one network device 110 and at least one terminal device 120. The number of network devices 110 and terminal devices 120 is not limited to the number shown in Figure 1 and may be any number.

[0055] The wireless communication system 100 can be a 5G system, a new radio (NR) system, a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a universal mobile telecommunication system (UMTS), a mobile communication system after the 5G network (for example, a 6G mobile communication system), a vehicle to everything (V2X) communication system, a device to device (D2D) communication system, an Internet of Things (IoT) communication system, an industrial Internet communication system, or a satellite communication system, etc., as well as three major application scenarios of the next-generation 5G mobile communication system, namely, an enhanced mobile broadband (eMBB) system, an ultra-reliable and low-latency communication (URLLC) system, and a massive machine type communication (eMTC) system.

[0056] The wireless communication system 100 may be composed of cells. Typically, a cell deploys at least one network device 110, enabling the network device 110 to provide communication services to each terminal device 120 within the cell. The wireless communication system 100 may also enable point-to-point communication, such as allowing multiple terminal devices 120 to communicate with each other.

[0057] The terminal device 120 may be a wireless terminal device capable of receiving network device scheduling information and instruction information. The terminal device 120 may be a device that provides voice and / or data connectivity to a user, or a handheld device with wireless connection function, or other processing device connected to a wireless modem.

[0058] The terminal device 120 is also referred to as user equipment (UE), mobile station (MS), mobile terminal (MT), customer premise equipment (CPE), etc. A terminal device is a device that includes wireless communication capabilities (providing voice / data connectivity to users). For example, it can be a handheld device or vehicle-mounted device with wireless connection capabilities. Currently, some examples of terminal devices include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in the Internet of Vehicles, wireless terminals in self-driving cars, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes. For example, wireless terminals in unmanned driving can be drones, helicopters, or airplanes. For example, wireless terminals in the Internet of Vehicles can be onboard equipment, complete vehicle equipment, onboard modules, vehicles, or ships. Wireless terminals in industrial control can be cameras, robots, or robotic arms. Wireless terminals in smart homes can be televisions, air conditioners, vacuum cleaners, speakers, or set-top boxes.

[0059] It should be noted that the terminal device 120 can be a device or apparatus with a chip, or a device or apparatus with an integrated circuit, or a chip, chip system, module or control unit in the device or apparatus shown above, and this application does not limit this. It should be noted that in this application, when referring to the terminal device 120, it can refer to the terminal device itself, or it can refer to the chip, functional module or integrated circuit in the terminal device that performs the method provided in this application, and this application does not limit this.

[0060] The network device 110 may be a device in a wireless network. For example, the network device 110 may be a device deployed in a radio access network that provides wireless communication capabilities for terminal devices. For example, the network device 110 may be a radio access network (RAN) node that connects the terminal device 120 to the wireless network. The network device 110 may also be referred to as an access network device, a RAN entity, an access node, a network node, or a communication device.

[0061] Specifically, the network device 110 may be an access network device for a cellular system related to the 3rd Generation Partnership Project (3GPP). For example, a 4G communication system, a 5G communication system, etc. The network device 110 may also be an access network device in an open access network (open RAN, O-RAN or ORAN) or a cloud radio access network (CRAN). Alternatively, the network device 110 may also be an access network device in a communication system obtained by integrating two or more of the above communication systems. Alternatively, the network device 110 may also be a satellite in a satellite communication system.

[0062] The network device 110 includes but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (for example, home evolved NodeB, or home Node B, HNB), baseband unit (BBU), access point (AP) in wireless fidelity (WIFI) system, macro base station, micro base station, wireless relay node, donor node, wireless controller in CRAN scenario, wireless backhaul node, transmission point (TP) or transmission and receiving point (TRP), etc., and can also be a network device in a 5G mobile communication system. For example, a next-generation NodeB (gNB), TRP, or TP in an NR system; or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system; or, the network device 110 may also be a network node constituting a gNB or a transmission point. For example, a centralized unit (CU), a distributed unit (DU), a centralized unit control plane (CU-CP), a centralized unit user plane (CU-UP), or a radio unit (RU). The CU and DU may be configured separately or included in the same network element, such as a BBU. The RU may be included in a radio frequency device or radio frequency unit. For example, in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). Alternatively, the network device 110 may also be a server, a wearable device, a vehicle, or an onboard device. For example, the access network device in the V2X technology may be a road side unit (RSU).

[0063] It should be noted that in different systems, CU (or CU-CP and CU-UP), DU or RU may have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called an open centralized unit (O-CU) or an open CU, DU may also be called an open distributed unit (O-DU), CU-CP may also be called an open centralized unit control plane (O-CU-CP), CU-UP may also be called an open centralized unit user plane (O-CU-UP), and RU may also be called an open radio unit (O-RU). This application does not limit this. Any of the CU, CU-CP, CU-UP, DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0064] Optionally, for network elements in the ORAN system, each network element may implement the protocol layer functions shown in Table 1 below.

[0065] Table 1

[0066] It should be noted that, in the ORAN system, the network device 110 in this application may be one or more network elements in Table 1 above.

[0067] The following describes the architecture of the CU and DU of an access network device. The access network device includes at least one CU and at least one DU. Optionally, the access network device also includes at least one RU.

[0068] The following is an introduction using the example of an access network device including a CU and a DU. The CU has some functions of the core network, and the CU may include a CU-CP and a CU-UP. The CU and the DU may be configured according to the protocol layer functions of the wireless network they implement. For example, the CU is configured to implement the functions of the packet data convergence protocol (PDCP) layer and the protocol layers above it (for example, the RRC layer and / or the SDAP layer). The DU is configured to implement the functions of the protocol layers below the PDCP layer (for example, the RLC layer, the MAC layer, and / or the physical (PHY) layer). For another example, the CU is configured to implement the functions of the protocol layers above the PDCP layer (such as the RRC layer and / or the SDAP layer), and the DU is configured to implement the functions of the PDCP layer and the protocol layers below it (for example, the RLC layer, the MAC layer, and / or the PHY layer, etc.).

[0069] When a CU includes a CU-CP and a CU-UP, the CU-CP is used to implement the control plane functions of the CU, and the CU-UP is used to implement the user plane functions of the CU. For example, when the CU is configured to implement the functions of the PDCP layer, RRC layer, and SDAP layer, the CU-CP is used to implement the RRC layer functions and the control plane functions of the PDCP layer, and the CU-UP is used to implement the SDAP layer functions and the user plane functions of the PDCP layer.

[0070] The CU-CP can interact with network elements in the core network that implement control plane functions. The network elements in the core network that implement control plane functions can be access and mobility function network elements, such as the access and mobility management function (AMF) in the 5G system. The access and mobility function network element is responsible for mobility management in the mobile network, such as location update of terminal devices, registration network of terminal devices, and switching of terminal devices.

[0071] The CU-UP can interact with network elements in the core network that implement user plane functions. Network elements in the core network that implement user plane functions, such as the user plane function (UPF) in the 5G system, are responsible for forwarding and receiving data in terminal devices.

[0072] The above configuration of CU and DU is only an example, and the functions of CU and DU can also be configured as needed. For example, the CU or DU can be configured to have the functions of more protocol layers, or the CU or DU can be configured to have partial processing functions of the protocol layer. For example, some functions of the RLC layer and the functions of the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are set in the DU. For another example, the functions of the CU or DU can be divided according to the service type or other system requirements. For example, according to the delay, the functions whose processing time needs to meet the smaller delay requirement are set in the DU, and the functions that do not need to meet the delay requirement are set in the CU.

[0073] The DU and RU can work together to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of the DU and RU can be configured in various ways according to the design. For example, the DU is configured to implement the baseband function, and the RU is configured to implement the mid-RF function. For another example, the DU is configured to implement the high-layer functions in the PHY layer, and the RU is configured to implement the low-layer functions in the PHY layer or to implement the low-layer functions and the RF functions. The high-layer functions in the physical layer may include a part of the functions of the physical layer, which is closer to the MAC layer, and the low-layer functions in the physical layer may include another part of the functions of the physical layer, which is closer to the mid-RF side.

[0074] Network device 110 may also be a core network device. For example, network device 110 may be a control plane functional entity including an access and mobility management function (AMF) or a session management function (SMF). The AMF is responsible for user access management, security authentication, mobility management, and other functions. The data plane functional entity includes the UPF. The UPF is responsible for managing user plane data transmission, traffic statistics, and other functions.

[0075] It should be noted that the network device 110 can be a device or apparatus with a chip, or a device or apparatus with an integrated circuit, or a chip, chip system, module or control unit in the aforementioned device or apparatus, and this application does not limit this. It should be noted that in this application, when referring to the network device 110, it can refer to the network device 110 itself, or it can refer to the chip, functional module or integrated circuit in the network device 110 that performs the method provided in this application, and this application does not limit this.

[0076] AI / ML models are machine learning models applied in the field of artificial intelligence, capable of automatically learning and adapting to patterns and regularities in diverse data sets. AI / ML models can be trained on large amounts of data, learning features and relationships, and then used to solve various intelligent tasks. AI models can be applied to a variety of fields and tasks, such as natural language processing, computer vision, speech recognition, and intelligent recommendations. Common AI / ML models include neural network models (such as deep neural networks and recursive neural networks), support vector machine models, and decision tree models.

[0077] An AI / ML model can automatically infer reasonable predictions about unknown data by learning and training from data. Based on input data (such as text, images, and audio) and model algorithms (such as neural networks, support vector machines, and decision trees), AI / ML models can generate outputs. Common outputs include classification, regression, clustering, and segmentation. AI / ML models are widely used in complex tasks such as prediction, recommendation, image processing, and natural language processing. Optimizing model performance and accuracy is an ongoing process.

[0078] The AI / ML model can be deployed on the network device 110, on the terminal device 120, or on both the network device 110 and the terminal device 120, enabling the network device 110 to intelligently process received data, thereby achieving inherent intelligence in the network and intelligence in the terminal device 120 communicating with the network device 110. The AI / ML model can provide services such as channel state information (CSI) compression feedback, cell reselection, and cell selection.

[0079] When the network device 110 needs to call the AI / ML model and / or use the AI / ML function, it can broadcast notification information to inform other terminal devices that the network device 110 that sends the notification information supports the AI / ML service. In an embodiment of the present application, the notification information broadcast by the network device 110 may be system information block (SIB) signaling, such as SIB23. SIB23 may include configuration information of the logical control channel (LCCH) that carries AI / ML service control information. In one embodiment, the format of SIB23 may be:

[0080] The logical control channel configuration (LCCH-Config) is the LCCH configuration information, used to configure the LCCH's time and frequency resources. lcch-WindowStartSlot is the LCCH's starting slot index. lcch-WindowDuration is the LCCH's time domain duration. lcch-BandStartSC is the LCCH's starting subcarrier index. lcch-BandWidth is the number of subcarriers occupied by the LCCH.

[0081] The network device 110 may configure the AI / ML service and determine that the identity (ID) of the configured AI / ML service and the configuration information of each protocol layer used to transmit the AI / ML service data constitute the service configuration information. The various protocol layers may be a packet data convergence layer (PDCL), a radio link control (RLC), a media access control (MAC), a physical layer (PHY), and the like. The network device 110 may constitute the service configuration information with the identity (ID) of the configured AI / ML service and the configuration information of each protocol layer used to transmit the AI / ML service data, and send the service configuration information or broadcast the service configuration information to the designated terminal device to inform the other terminal devices 120 that the network device 110 that sends the notification information supports the relevant configuration of the AI / ML service.

[0082] In an embodiment of the present application, the service configuration information sent by the network device 110 may be an AI / ML configuration (AIMLConfiguration) signaling. The AI / ML configuration signaling includes the ID of the AI / ML service, the mapping configuration of the logical transport channel (LTCH) for carrying the business traffic of the AI / ML service and the physical downlink shared channel (PDSCH) and / or the physical uplink shared channel (PUSCH), and the configuration information of each protocol layer. In one embodiment, the format of the AI / ML configuration signaling may be:

[0083] Among them, PDSCH-ConfigLTCH is used to describe the mapping relationship between LTCH and PDSCH and / or PUSCH that carry the business traffic of AI / ML services. AIML-ServiceInfo contains the ID of AI / ML service and the radio network temporary identifier (RNTI) value (i.e., a-RNTI) used when transmitting the business of AI / ML service corresponding to the ID of AI / ML service.

[0084] After receiving the service configuration information, the terminal device 120 can determine whether it needs the AI / ML service provided by the network device 110 based on its own needs. If the terminal device 120 needs one or more AI / ML services provided by the network device 110, it can send interest information to the network device 110 to inform the network device 110 that the terminal device 120 sending the interest information needs one or more AI / ML services of the network device 110. In this embodiment of the present application, the interest information sent by the terminal device 120 to the network device 110 can be AI / ML interest indication (AIMLInterestIndication) signaling. The AI / ML interest indication signaling is used to indicate that one or more AI / ML services provided by the network device 110 are required. In one embodiment, the format of the AI / ML interest indication signaling can be:
