Technical Field

[0002] The present application relates to the field of wireless technology, and in particular to a communication method, related equipment and system. Background Art

[0003] Wireless communication can be a transmission communication between two or more communication nodes without propagating through conductors or cables. The communication nodes generally include terminal devices and wireless access devices.

[0004] Currently, in wireless communication systems, wireless access devices can calculate and determine signal transmission resources. For example, these transmission resources may include time domain resources and frequency domain resources used to carry signals. Accordingly, terminal devices can transmit and receive signals using these transmission resources. In this way, the wireless access device can provide network access wireless communication services for at least one terminal device.

[0005] With the development of communication technology, communication management services have emerged in wireless communication systems to manage wireless access communication services. However, how to manage the transmission performance of the communication management services themselves is a technical problem that needs to be solved urgently.

[0006] Summary of the Invention

[0007] The present application provides a communication method, related equipment and system, which are used to manage wireless access communication services through communication management services to improve the service quality of network access. At the same time, the transmission configuration information sent by the first communication unit can also ensure the service quality of data transmission of the communication management service to improve data transmission performance.

[0008] In a first aspect, the present application provides a communication method, which is performed by a first communication unit. The first communication unit may be a communication device, or the first communication unit may be a partial component of the communication device (such as a processor, a chip, or a chip system, etc.), or the first communication unit may be a logic module or software that implements all or part of the functions of the communication device. In the first aspect and its possible implementation, the method is described as being performed by the first communication unit. In the method, the first communication unit determines transmission configuration information, which is used to configure the quality of service (QoS) of data transmission; the data transmission is the transmission of service data of a communication management service between a terminal device and a wireless access device; wherein the communication management service is used to manage a wireless access communication service between the wireless access device and at least one terminal device, and the at least one terminal device includes the terminal device; the first communication unit sends the transmission configuration information.

[0009] Based on the above technical solution, the communication management service is used to manage the wireless access communication service between the wireless access device and the terminal device. The transmission configuration information sent by the first communication unit is used to configure the QoS for data transmission of service data for the communication management service between the terminal device and the wireless access device. The recipient of this transmission configuration information can then subsequently transmit service data for the communication management service based on this transmission configuration information. Thus, in the above technical solution, while the communication management service manages the wireless access communication service to improve the quality of service of network access, the transmission configuration information sent by the first communication unit can also ensure the quality of service for data transmission of the communication management service, thereby improving data transmission performance.

[0010] It should be understood that the QoS of data transmission can be replaced by other descriptions, such as the transmission performance of data transmission, the service performance of data transmission, etc.

In other words, the communication management service can be a service that improves the service quality of wireless access communication services based on an intelligent approach, or the communication management service can be a service that intelligently manages the service quality of wireless access communications. Accordingly, the communication management service can also be replaced by a communication configuration service, a communication optimization service, etc.

Accordingly, the communication management service may include intelligent management of communication beams, which is also called AI-enabled beam management service or AI model-based beam management service.

[0015] Optionally, the service data of the communication management service includes an AI model corresponding to at least one of the aforementioned services to implement management of communication parameters corresponding to the at least one of the aforementioned services. For example, the AI ​​model included in the service data of the communication management service may include an AI model for an AI-based CSI feedback service to implement intelligent management of CSI through the AI ​​model; for another example, the AI ​​model included in the service data of the communication management service may include an AI model for an AI-based beam management service to implement intelligent management of communication beams through the AI ​​model.

[0016] For example, the communication parameters involved in the wireless access communication service may include positioning information. Accordingly, the communication management service may include intelligent management of positioning information, which is also called an AI-enabled location positioning service or an AI model-based location positioning service.

[0017] It should be understood that the AI ​​model can be used to calculate the communication parameters involved in the wireless access communication service (including at least one of CSI, communication beam, and positioning information) through AI to obtain calculation results, which can be used for the management of the wireless access communication service (including at least one of configuration, update, and optimization).

[0018] Optionally, the data of the communication management service and the data of the wireless access communication service may be transmitted through a radio bearer (RB) between the terminal device and the wireless access device. For example, the data of the communication management service may be transmitted through a computing radio bearer (CRB), and the data of the wireless access communication service may be transmitted through at least one of a signaling radio bearer (SRB) and a data radio bearer (DRB).

[0106] First, some of the terms used in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0107] (1) Configuration and pre-configuration: In this application, configuration and pre-configuration will be used at the same time. Configuration refers to the network equipment such as base stations or servers sending some parameter configuration information or parameter values ​​to the terminal through messages or signaling, so that the terminal can determine the communication parameters or resources during transmission based on these values ​​or information. Pre-configuration is similar to configuration. It can be a way for network equipment such as base stations or servers to send parameter information or values ​​to the terminal through a communication link or carrier; it can also be a way to give the definition of corresponding parameters or parameter values ​​in the standard, or by setting the relevant parameters or values ​​in the terminal device in advance. This application does not limit this. Furthermore, these values ​​and parameters can be changed or updated.

[0108] (2) In this application, “used for indication” can include direct indication and indirect indication. When describing that a certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0109] In this application, the information indicated by the indication information is referred to as the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated. For example, it can be implemented by direct indication, such as by indicating the information to be indicated itself or the index of the information to be indicated. It can also be implemented by indirectly indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved with the help of the arrangement order of each information agreed in advance (for example, stipulated in the protocol), thereby reducing the indication overhead to a certain extent.

[0110] The information to be indicated can be sent as a whole, or divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different. The specific sending method is not limited in this application. Among them, the sending period and / or sending time of these sub-information can be predefined, for example, predefined according to a protocol, or configured by the transmitting device by sending configuration information to the receiving device. Among them, the configuration information can, for example, but not limited to, include one or a combination of at least two of RRC signaling, medium access control (MAC) layer signaling and physical layer signaling. Among them, MAC layer signaling, for example, includes a medium access control control element (MAC CE); physical layer signaling, for example, includes downlink control information (DCI).

[0111] (3) The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "At least one" means one or more, and "more" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B and C" includes A, B, C, AB, AC, BC or ABC. In addition, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, timing, priority or importance of multiple objects.

[0112] (4) "Sending" and "receiving" in the embodiments of the present application indicate the direction of signal transmission. In the present application, when entity A sends information to entity B, it can be that A sends it directly to B, or that A sends it indirectly to B through other entities. Similarly, when entity B receives information from entity A, it can be that entity B directly receives the information sent by entity A, or that entity B indirectly receives the information sent by entity A through other entities. Entities A and B here can be RAN nodes or terminals, or modules inside RAN nodes or terminals. The sending and receiving of information can be information interaction between a RAN node and a terminal, for example, information interaction between a base station and a terminal; the sending and receiving of information can also be information interaction between two RAN nodes, for example, information interaction between a CU and a DU; the sending and receiving of information can also be information interaction between different modules inside a device, for example, information interaction between a terminal chip and other modules of the terminal, or information interaction between a base station chip and other modules in the base station. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface.

[0113] Please refer to Figure 1, which is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. As shown in Figure 1, the communication system includes a radio access network (RAN) 100 and a core network 200.

[0114] Optionally, the communication system 1000 may further include the Internet 300 .

[0115] In Figure 1 , RAN 100 includes at least one RAN node (e.g., 110a and 110b in Figure 1 , collectively referred to as 110) and may also include at least one terminal (e.g., 120a-120j in Figure 1 , collectively referred to as 120). RAN nodes may also be referred to as wireless access devices, network devices, access network devices, etc.

[0116] In Figure 1 , RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment (not shown in Figure 1 ). Terminal 120 is wirelessly connected to RAN node 110, and RAN node 110 is wirelessly or wiredly connected to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 may be separate, distinct physical devices, or they may be a single physical device that integrates the logical functions of a core network device with the logical functions of a RAN node. Terminals and RAN nodes may be connected to each other via wired or wireless means.

[0117] RAN100 may be an evolved universal terrestrial radio access (E-UTRA) system, a new radio (NR) system, or a future radio access system defined in the 3rd Generation Partnership Project (3GPP). RAN100 may also include two or more of the aforementioned different radio access systems. RAN100 may also be an open RAN (O-RAN).

[0118] A RAN node, also known as a radio access network device, RAN entity, or access node, facilitates wireless access to a communication system by a terminal. In one application scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a fifth-generation (5G) mobile communication system, a next-generation base station in a sixth-generation (6G) mobile communication system, or a base station in a future mobile communication system. A RAN node can be a macro base station (such as 110a in Figure 1), a micro base station, an indoor station (such as 110b in Figure 1), a relay node, or a donor node.

[0119] In another application scenario, multiple RAN nodes can collaborate to help terminals achieve wireless access, with different RAN nodes implementing portions of the base station's functions. For example, a RAN node can be a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). The CU implements the base station's radio resource control protocol and packet data convergence protocol (PDCP) functions, and can also implement the service data adaptation protocol (SDAP) functions; the DU implements the base station's radio link control layer and MAC layer functions, and can also implement some or all of the physical layer functions. For detailed descriptions of each of the above protocol layers, please refer to the relevant technical specifications of 3GPP. The RU can be used to implement the transmission and reception of radio frequency signals. The CU and DU can be two independent RAN nodes, or they can be integrated into the same RAN node, such as in a baseband unit (BBU). The RU can be included in radio frequency equipment, such as a remote radio unit (RRU) or an active antenna unit (AAU). The CU can be further divided into two types of RAN nodes: CU-control plane and CU-user plane.

[0120] In different systems, RAN nodes may have different names. For example, in an open access network (open RAN, O-RAN or ORAN) system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0121] The communication between the access network device and the terminal device follows a certain protocol layer structure. The protocol layer may include a control plane protocol layer and a user plane protocol layer. The control plane protocol layer may include at least one of the following: a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a media access control (MAC) layer, or a physical (PHY) layer. The user plane protocol layer may include at least one of the following: a service data adaptation protocol (SDAP) layer, a PDCP layer, an RLC layer, a MAC layer, or a physical layer.

[0122] For the correspondence between network elements in the ORAN system and their achievable protocol layer functions, please refer to Table 1 below.

[0123] Table 1

[0124] The embodiments of the present application do not limit the specific technology and specific device form used by the RAN node. For ease of description, the following description uses a base station as an example of a RAN node.

[0125] A terminal is a device with wireless transceiver capabilities that can send signals to a base station or receive signals from a base station. A terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. A terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, wearable device, vehicle, airplane, ship, robot, robotic arm, smart home device, etc. The embodiments of this application do not limit the specific technology and specific device form adopted by the terminal.

[0126] Base stations and terminals can be fixed or mobile. They can be deployed on land, indoors or outdoors, handheld or vehicle-mounted; on water; or on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.

[0127] The roles of base stations and terminals can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile base station. To terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station. However, to base station 110a, 120i is a terminal, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via a base station-to-base station interface protocol. In this case, 120i is also a base station relative to 110a. Therefore, base stations and terminals can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be referred to as communication devices with base station functionality, while 120a-120j in Figure 1 can be referred to as communication devices with terminal functionality.

[0128] Communication between base stations and terminals, between base stations, and between terminals can be carried out through authorized spectrum, unauthorized spectrum, or both; communication can be carried out through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0129] In this application, the functions of the base station can also be performed by a module in the base station (such as a chip), or by a control subsystem that includes the base station function. The control subsystem that includes the base station function here can be the control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city. The functions of the terminal can also be performed by a module in the terminal (such as a chip or modem), or by a device that includes the terminal function.

[0130] In a wireless communication system, a wireless access device can calculate and determine signal transmission resources. For example, these resources may include time-domain resources and frequency-domain resources used to carry the signal. Accordingly, a terminal device can transmit and receive signals using these transmission resources. In this way, the wireless access device can provide network access communication services for the terminal device.

[0131] However, in communication networks, how to improve data transmission performance is a technical problem that needs to be solved urgently.

[0132] In one possible implementation, a communication management service implemented through intelligent technology can intelligently manage (including optimizing, configuring, and updating) the communication services that provide network access to improve data transmission performance. This intelligent technology may include artificial intelligence, neural network technology, and machine learning technology.

[0133] For example, taking the AI ​​method as an example, wireless scenarios such as AI-enabled beam management and AI-enabled CSI feedback can be used to achieve intelligent management (including optimization / configuration / update, etc.) of communication services that provide network access. Generally, there are two ways to enable AI-enabled wireless air interface enhancement, namely unilateral AI and bilateral AI.

[0134] In an implementation example, unilateral AI can be to deploy an AI model on one side of a terminal device or wireless access device for a certain wireless service feature.

[0135] For example, as shown in Figure 2a, after the terminal device receives the wireless communication signal from the wireless access device in step A1, in step A2, the terminal device can perform AI processing on the AI ​​model deployed on the terminal device based on the wireless communication signal (for example, AI inference shown in Figure 2a); thereafter, in step A3, the terminal device can send the result of AI inference to the wireless access device via an RRC message. The specific RRC message type is not limited in this article.

[0136] For another example, as shown in Figure 2b, after the wireless access device receives the wireless communication signal from the wireless access device in step B1, in step B2, the wireless access device may perform AI processing (for example, AI inference shown in Figure 2b) on the AI ​​model deployed on the wireless access device based on the wireless communication signal; thereafter, in step B3, the wireless access device may send the result of AI inference to the terminal device via an RRC message.

[0137] In another implementation example, bilateral AI is for a certain wireless service feature, and both the terminal device and the wireless access device deploy AI models. For example, as shown in Figure 2c, after the terminal device receives the wireless communication signal from the wireless access device in step C1, in step C2, the terminal device can perform AI processing on the AI ​​model deployed on the terminal device based on the wireless communication signal (for example, AI inference shown in Figure 2c); thereafter, in step C3, the terminal device can send an AI model monitoring report to the wireless access device (wherein the AI ​​model monitoring report can include one or more of the following: the inference accuracy of the AI ​​model, the number of times the AI ​​model is used, the usage time of the AI ​​model, and a notification that the inference accuracy of the AI ​​model is lower than a threshold); the wireless access device can subsequently perform AI inference in step C4, and in step C5, the wireless access device can send the result of the AI ​​inference to the terminal device via an RRC message.

[0138] In addition, the AI ​​model applied to the wireless air interface (for example, the AI ​​model deployed on the terminal device in Figure 2a or Figure 2c, or the AI ​​model deployed on the wireless access device in Figure 2b or Figure 2c) is generally generated based on wireless network data training within a certain time period. However, with the changes in the wireless network environment and the aging of the AI ​​model itself (that is, the phenomenon that the AI ​​model's reasoning accuracy for newly generated data gradually decreases), the accuracy of the AI ​​model decreases. Therefore, based on the changes in the accuracy of the AI ​​model (such as the accuracy is lower than a specific threshold) or the periodic requirements for AI model updates, it is necessary to retrain the AI ​​model using new wireless network data to obtain a new AI model with the required accuracy.

[0139] Generally, due to the limited computing power, storage space, and battery power of terminal devices, it may be difficult to meet the needs of AI model training. Therefore, the training of AI models on the terminal device side is usually completed by wireless access devices, that is, the terminal device transmits the data required for AI model training to the wireless access device through the wireless air interface. The wireless access device performs AI model training on the terminal device side and sends the trained AI model on the wireless access device side to the terminal device through the wireless air interface channel. Among them, the transmission of AI business data (such as AI models, AI model training data (hereinafter referred to as AI data)) on the wireless air interface has the following characteristics: the amount of transmitted AI business data is large, and the AI ​​business data comes from the terminal device or the wireless access device.

[0140] For the communication service that the wireless access device provides network access to the terminal device (i.e., the wireless access communication service mentioned later), the data of the communication service can be transmitted through the signaling radio bearer (SRB) and / or the data radio bearer (DRB). Among them, SRB and DRB are used to transmit air interface signaling messages and third-party application service data, respectively. Generally, the amount of data transmitted by DRB is relatively small, and the transmitted data comes from third-party applications outside the wireless communication network. Therefore, the current DRB may not be suitable for transmitting AI data. In order to support the interaction of AI data between the terminal device and the wireless access device, as shown in Figure 2d, in addition to DRB and SRB, AI data can be transmitted between the terminal device and the wireless access device through the computing radio bearer (CRB). Among them, the CRB between the terminal device and the network device can be transmitted through the data analysis protocol (DAP). For example, CRB and DAP can be new radio bearer types and control management protocols proposed for the data transmission of communication management services (which can have RAN-AI model / data distribution, security (including integrity protection, encryption and decryption) and other functions).

[0141] However, due to the large scale of AI data (such as AI model data, data required for AI model training, etc.) (usually at the level of megabytes (MB), gigabytes (GB), or even terabytes (TB)), it is necessary to consume more wireless air interface resources. Currently, there is no relevant implementation solution for the transmission guarantee of AI data, which will make it difficult for wireless access devices to reasonably allocate wireless network resources for AI data transmission, resulting in waste of wireless resources and reduced resource utilization. For example, when the wireless access device allocates too many wireless resources for AI data transmission, it will cause waste of wireless resources and even affect the user's experience of other services (because the wireless resources are occupied by AI data for a long time, the DRB for the transmission of other user services cannot obtain sufficient wireless resources for transmission). For another example, when the wireless access device allocates too few wireless resources for AI data transmission, it may cause the transmission of AI data to fail.

[0142] To this end, how to manage the transmission performance of the communication management service itself while implementing intelligent management (such as optimization / configuration / update) of the communication service that provides network access to improve data transmission performance through intelligent technology is a technical problem that needs to be solved urgently.

[0143] To address the aforementioned issues, the present application provides a communication method, related devices, and system for managing wireless access communication services through a communication management service to improve the quality of service for network access. Furthermore, the transmission configuration information sent by the first communication unit can also ensure the quality of service for data transmission of the communication management service, thereby improving data transmission performance. This will be described in detail below with reference to the accompanying drawings.

[0144] The following will combine the examples shown in Figure 3a / Figure 3b / Figure 3c / Figure 3d / Figure 3e to exemplify the network architecture applied to the communication method provided in this application. In the following example, the first communication unit can be a new logical functional entity introduced for intelligent scenarios (such as AI application scenarios), responsible for AI-related functions such as AI model training, deployment, performance monitoring and AI data processing. The communication method provided later supports the management of QoS of service transmission of communication management services (including optimization / configuration / update, etc.) by enhancing the functionality of the first communication unit in the new intelligent architecture. Generally, CU is responsible for functions such as interface control and mobility management of terminal equipment, and DU is responsible for functions such as access link management, wireless channel management and resource mapping of terminal equipment.

[0145] Optionally, in the examples shown in Figures 3a / 3b / 3c / 3d / 3e, the first communication unit (or wireless access device, or CU, or DU) can be an ORAN network element (or a module in an ORAN network element), including but not limited to one or more of O-CU-CP, O-CU-UP, O-DU, and O-RU.

[0146] In Figure 3a, the wireless access device may include a CU and a DU. The first communication unit mentioned below may be a module in the wireless access device that is independent of the CU and the DU. The first communication unit may communicate with the CU via a G1 interface, and the first communication unit may also communicate with the DU via a G2 interface. In addition, in the architecture shown in Figure 3a, the first communication unit may be referred to as an AI entity, a RAN AI entity, etc. The first communication unit may be independently deployed as a new network element entity or deployed in conjunction with the CU, but is logically independent of the CU.

[0147] It should be understood that in Figure 3a, the CU, DU or terminal device can serve as the second communication unit, that is, the second communication unit can be the CU, DU or terminal device, or the second communication unit can be a module in the CU, a module in the DU or a module in the terminal device.

[0148] In Figure 3b, the wireless access device may include a CU and a DU, and the first communication unit mentioned later may be a module independent of the wireless access device, wherein the first communication unit may communicate with the wireless access device through the E2 interface. In the architecture shown in Figure 3b, the first communication unit is mainly responsible for enhancing the radio resource management (RRM) policy management, service diversion control, access management control and other functions of the wireless access device, that is, the first communication unit may add an AI QoS management function module to support the management of QoS of service transmission of communication management services (including optimization / configuration / update). In addition, the architecture shown in Figure 3b can be applied to open RAN scenarios. For example, the first communication unit may be a radio access network near-real-time intelligent controller (Near-Real time rAN intelligent controller, Near-RT RIC) functional entity, or the first communication unit may be a basic platform function component (platform function module) of Near-RT RIC, etc.

[0149] It should be understood that in Figure 3b, the wireless access device, CU, DU or terminal device can serve as the second communication unit, that is, the second communication unit can be a CU, DU or terminal device, or the second communication unit can be a module in the CU, a module in the DU or a module in the terminal device.

[0150] In Figure 3c, the wireless access device may include a CU and a DU. The first communication unit mentioned below may be a module built into the CU, wherein the first communication unit may communicate with the DU via the F1 interface. In other words, by enhancing the CU functionality, namely, adding an AI QoS management function module to support QoS management (including optimization / configuration / update) for service transmission of communication management services, and enhancing the F1 interface between the CU and DU, the interaction of transmission configuration information mentioned below is supported.

[0151] It should be understood that in Figure 3c, the DU or the terminal device can serve as the second communication unit, that is, the second communication unit can be the DU or the terminal device, or the second communication unit can be a module in the DU or a module in the terminal device.

[0152] Optionally, in the above FIG. 3a to FIG. 3c, a scenario in which the CU and DU are separated in the radio access network is taken as an example. However, in actual applications, the radio access network may also be implemented in other ways.

[0153] For example, compared to the architectures shown in Figures 3a and 3c, in Figure 3d, the wireless access device may not distinguish between scenarios where the CU and DU are separated, that is, the first communication unit may be a logical module / physical module in the wireless access device. It should be understood that in Figure 3d, the terminal device may serve as the second communication unit, that is, the second communication unit may be the terminal device, or the second communication unit may be a module in the terminal device.

[0154] For another example, compared to the architecture shown in Figure 3b, in Figure 3e, the wireless access device may not distinguish between scenarios where the CU and DU are separated, i.e., the first communication unit may be a logical module / physical module independent of the wireless access device. It should be understood that in Figure 3e, the wireless access device or terminal device may serve as the second communication unit, i.e., the second communication unit may be the wireless access device or the terminal device, or the second communication unit may be a module in the wireless access device or the terminal device.

[0155] It should be understood that the second communication unit mentioned later can be any one of the wireless access device, terminal device, CU or DU in the architecture shown in Figures 3a to 3e. The specific implementation process is detailed in the description of the embodiments below.

[0156] Please refer to FIG4 , which is a schematic diagram of the communication method provided in this application. The method includes the following steps.

[0157] It should be noted that FIG4 illustrates this method using the first communication unit and the second communication unit as examples of the execution entities of the interaction diagram. The first communication unit and the second communication unit may be the first communication unit and the second communication unit in any of FIG3a through FIG3e. For example, the first communication unit may be an internal module of a wireless access device or a device / module independent of the wireless access device. Furthermore, the second communication unit may be a wireless access device, a CU, a DU, or a terminal device, or a module in a wireless access device, a module in a CU, a module in a DU, or a module in a terminal device.

[0158] It should be understood that in Figure 4, the first communication unit may be a communication device, or the first communication unit may be a partial component of the communication device (such as a processor, chip, or chip system), or the first communication unit may be a logic module or software that implements all or part of the functions of the communication device. Similarly, the second communication unit may be a communication device, or the second communication unit may be a partial component of the communication device (such as a processor, chip, or chip system), or the second communication unit may be a logic module or software that implements all or part of the functions of the communication device.

[0159] Optionally, the first communication unit (or wireless access device, or CU, or DU) executing the methods shown in Figures 4 to 10 can be an ORAN network element (or a module in an ORAN network element), including but not limited to one or more of O-CU-CP, O-CU-UP, O-DU, and O-RU.

[0160] S401. A first communication unit sends transmission configuration information, and a second communication unit receives the transmission configuration information. The transmission configuration information is used to configure quality of service (QoS) for data transmission, where the data transmission is the transmission of service data of a communication management service between a terminal device and a wireless access device; the communication management service is used to manage a wireless access communication service between the wireless access device and at least one terminal device, where the at least one terminal device includes the terminal device.

[0161] It should be understood that the communication management service is used to manage wireless access communication services. It can be understood that the communication management service is used to manage the communication parameters involved in the wireless access communication service in an intelligent manner (including at least one of configuration, update, and optimization). The intelligent manner may include a manner enabled by technologies such as artificial intelligence (AI), neural networks, and machine learning. In other words, the communication management service can be a service that improves the service quality of wireless access communication services based on an intelligent approach. Accordingly, the communication management service can also be replaced by a communication configuration service, a communication optimization service, etc.

[0162] For example, the communication parameters involved in the wireless access communication service may include channel state information (CSI). Accordingly, the communication management service may include intelligent management of CSI, which is also called AI-enabled CSI feedback service or AI model-based CSI feedback service.

[0163] For example, the communication parameters involved in the wireless access communication service may include communication beams. Accordingly, the communication management service may include intelligent management of communication beams, which is also called AI-enabled beam management service or AI model-based beam management service.

[0164] Optionally, the service data of the communication management service includes an AI model corresponding to at least one of the aforementioned services to implement management of communication parameters corresponding to the at least one of the aforementioned services. For example, the AI ​​model included in the service data of the communication management service may include an AI model for an AI-based CSI feedback service to implement intelligent management of CSI through the AI ​​model; for another example, the AI ​​model included in the service data of the communication management service may include an AI model for an AI-based beam management service to implement intelligent management of communication beams through the AI ​​model.

[0165] For example, the communication parameters involved in the wireless access communication service may include positioning information. Accordingly, the communication management service may include intelligent management of positioning information, which is also called an AI-enabled location positioning service or an AI model-based location positioning service.

[0166] It should be understood that the AI ​​model can be used to calculate the communication parameters involved in the wireless access communication service (including at least one of CSI, communication beam, and positioning information) through AI to obtain calculation results, which can be used for the management of the wireless access communication service (including at least one of configuration, update, and optimization).

[0167] Optionally, the data of the communication management service and the data of the wireless access communication service can be transmitted through a radio bearer (RB) between the terminal device and the wireless access device. As shown in Figure 2d above, the data of the communication management service can be transmitted through a computing radio bearer (CRB), and the data of the wireless access communication service can be transmitted through at least one of a signaling radio bearer (SRB) and a data radio bearer (DRB).

[0168] It should be understood that the QoS of data transmission of the communication management service can be replaced by other descriptions, such as the transmission performance of data transmission of the communication management service, the service performance of data transmission of the communication management service, etc.

[0169] Optionally, the service data involved in the data transmission of the communication management service may include at least one of AI model information and data required for AI model training. The AI ​​model information may include at least one of parameter scale information of the AI ​​model, structural information of the AI ​​model, and intermediate results of the AI ​​model training (such as training hyperparameters).

[0170] Optionally, the transmission configuration information sent by the first communication unit in step S401 includes at least one item of the following information A refers to information D.

[0171] Information A. Communication management service data transmission priority.

[0172] Specifically, the first communication unit may indicate the priority of data transmission for the communication management service through information A. Subsequently, after receiving information A, the second communication unit may schedule the data for each service based on the priority indicated by information B. For example, the first communication unit may determine the priority of AI service data transmission based on information such as the real-time requirements or urgency of the communication management service. Subsequently, the second communication unit may determine the scheduling order of the communication management service based on information A.

[0173] For example, take the case where the data transmission of the communication management service includes multiple AI model data. When the update cycle of the AI ​​model corresponding to one AI model data (denoted as AI model 1) is shorter (such as updated once every 5 minutes / 10 minutes), and the update cycle of the AI ​​model corresponding to another AI model data (denoted as AI model 1) is longer (such as updated once every 7 days / 10 days), the priority corresponding to the former is higher than the priority corresponding to the latter. In other words, the data transmission priority of the model data corresponding to AI model 1 is higher than the data transmission priority of the model data corresponding to AI model 2. The information A determined by the first communication unit can be used to indicate the priority scheduling of the data transmission of the model data corresponding to AI model 1, while the model data corresponding to AI model 2 can be transmitted during the off-peak hours (such as early morning).

[0174] Information B. The data size of data transmission for communication management services.

[0175] Specifically, the first communication unit can indicate the data scale of the data transmission of the communication management service through information B. Subsequently, after receiving information B, the second communication unit can determine the resources required for the data transmission of the communication management service based on information B (such as bandwidth resources in the frequency domain, time domain resources in the time domain, etc.). For example, the information B can determine the physical resource block (PRB) resources used to transmit the communication management service.

[0176] Information C. Packet loss rate requirements for data transmission of communication management services.

[0177] Specifically, the first communication unit may indicate the packet loss rate requirement of the data transmission of the communication management service through information C. Subsequently, after receiving the information C, the second communication unit may determine the allowable packet loss rate of the data transmission of the communication management service based on the information C.

[0178] For example, the data transmission of the communication management service includes AI model data and AI training data. Generally, the data scale of the AI ​​model data is large, and the data scale of the AI ​​training data is small. The information C sent by the first communication unit can indicate that the packet loss rate requirement of the AI ​​model data is high, that is, the value of the packet loss rate requirement can be a small value (because the receiving end needs to recover and assemble the AI ​​model based on the received data packet, and it is not easy to recover the AI ​​model if too many packets are lost); and the information C sent by the first communication unit can indicate that the packet loss rate requirement of the AI ​​training data is low, that is, the value of the packet loss rate requirement can be a large value.

[0179] Information D. Data transmission delay requirements for communication management services.

[0180] Specifically, the first communication unit may indicate the delay requirement of data transmission of the communication management service through information D, and subsequently, after receiving information D, the second communication unit may determine the delay requirement of data transmission of the communication management service based on the information D.

[0181] For example, because a terminal device or wireless access device (e.g., an aircraft, satellite, etc.) may be in a mobile state, to avoid handovers caused by movement, data transmission of communication management services must be completed before the terminal device switches from a source wireless access device to a target wireless access device (or from a source base station to a target base station). Therefore, the delay requirement indicated by information D herein may be greater than or equal to the processing delay consumed by the terminal device switching from its current location to the target wireless access device.

[0182] In one possible implementation, the transmission configuration information sent by the first communication unit in step S401 includes at least one of first configuration information and second configuration information; wherein the first configuration information is used to configure the QoS of data transmission for the communication management service on the terminal device, and the second configuration information is used to configure the QoS of data transmission for the communication management service on the wireless access device. Specifically, the transmission configuration information sent by the first communication unit may include at least one of the first configuration information and the second configuration information, so that the terminal device and the wireless access device can subsequently transmit data of the communication management service based on the first configuration information and the second configuration information, respectively, to ensure the end-to-end quality of service of data transmission of the communication management service between the terminal device and the wireless access device.

[0183] In one possible implementation, the business data of the communication management business includes an AI model. Accordingly, the process of the first communication unit determining the transmission configuration information in step S301 may include: the first communication unit determines the transmission configuration information based on at least one of the following items (that is, the basis for determining the transmission configuration information includes at least one of the following items): parameter scale information of the AI ​​model information contained in the business data, structural information of the AI ​​model corresponding to the AI ​​model information contained in the business data, transmission requirement information of the business data, data volume information required for training the AI ​​model corresponding to the AI ​​model information contained in the business data, and mobile feature information of the terminal device using the AI ​​model corresponding to the AI ​​model information contained in the business data.

[0184] It should be noted that, for the first communication unit, part or all of the above-mentioned at least one determination basis can be determined by pre-configuration, or part or all of the above-mentioned at least one determination basis can be determined based on information sent by other devices. This will be described below in combination with implementation example A and implementation example B.

[0185] In implementation example A, before the first communication unit sends the transmission configuration information in step S302, the method may further include: the first communication unit receiving request information, where the request information is used to request the transmission configuration information. Specifically, the first communication unit may receive request information for requesting the transmission configuration information, so that the first communication unit triggers the sending of the transmission configuration information based on the request information, making the solution applicable to scenarios where other devices (e.g., terminal devices or wireless access devices) request transmission configuration information.

[0186] Optionally, the business data of the communication management service includes an artificial intelligence (AI) model, and the request information includes at least one of the following: parameter scale information of the AI ​​model information contained in the business data, structural information of the AI ​​model corresponding to the AI ​​model information contained in the business data, transmission requirement information of the business data, data volume information required for training the AI ​​model corresponding to the AI ​​model information contained in the business data, and mobile feature information of the terminal device using the AI ​​model corresponding to the AI ​​model information contained in the business data.

[0187] It should be understood that in implementation example A, the request information received by the first communication unit may come from the second communication unit, that is, the terminal device, CU, DU or wireless access device may send the request information to the first communication unit.

[0188] In implementation example B, before the first communication unit sends the transmission configuration information in step S302, the method may further include: the first communication unit receives capability information, and the capability information is used to determine the transmission configuration information; wherein the capability information includes at least one of the following: an identifier of an AI application scenario supported by the terminal device, mobile feature information of the terminal device, or AI capability information supported by the terminal device. Specifically, the first communication unit can receive capability information indicating the capabilities of the terminal device, and determine the transmission configuration information based on the capability information, so that the transmission configuration information determined by the first communication unit can be adapted to the capability information of the terminal device, thereby avoiding data transmission failure of the communication management service.

[0189] It should be understood that in implementation example B, the capability information received by the first communication unit may come from the second communication unit, that is, the terminal device, CU, DU or wireless access device may send the capability information to the first communication unit.

[0190] S402. The second communication unit transmits service data based on the transmission configuration information.

[0191] In one possible implementation, in step S402, the second communication unit transmitting the communication management service data based on the transmission configuration information includes: configuring, by the second communication unit, transmission resources between the terminal device and the wireless access device based on the transmission configuration information; and sending or receiving, by the second communication unit, service data of the communication management service based on the transmission resources. Specifically, after the second communication unit receives the transmission configuration information in step S401, the second communication unit may configure, in step S402, the transmission resources between the terminal device and the wireless access device based on the transmission configuration information, so as to send or receive service data of the communication management service via the transmission resources.

[0192] Based on the technical solution shown in Figure 4, the communication management service is used to manage wireless access communication services between a wireless access device and at least one terminal device. The transmission configuration information sent by the first communication unit in step S401 is used to configure the QoS for data transmission of service data for the communication management service between the terminal device and the wireless access device. Thereafter, the second communication unit can subsequently transmit the service data for the communication management service based on the transmission configuration information in step S402. Thus, while the communication management service manages the wireless access communication service to improve the quality of service of network access, the transmission configuration information sent by the first communication unit can also ensure the quality of service for data transmission of the communication management service, thereby improving data transmission performance.

[0193] In the technical solution shown in Figure 4, as described in step S401, the transmission configuration information sent by the first communication unit may include at least one of the first configuration information and the second configuration information. Accordingly, the second communication unit receiving the transmission configuration information may be at least one of the terminal device and the wireless access device, which will be described below in conjunction with more implementation examples.

[0194] Implementation example 1: in the technical solution shown in FIG4 , the second communication unit may be a wireless access device.

[0195] As an application example of implementation example 1, when the second communication unit may be a wireless access device (or a module in the wireless access device), as shown in FIG5 , the following steps are included.

[0196] S501. A first communication unit sends transmission configuration information to the wireless access device, wherein the transmission configuration information includes at least second configuration information, and the second configuration information is used to configure QoS of data transmission for the communication management service on the wireless access device.

[0197] S502. The wireless access device transmits the service data of the communication management service based on the transmission configuration information. That is, the wireless access device transmits the service data of the communication management service between the wireless access device and the terminal device based on the transmission configuration information.

[0198] Specifically, in the implementation process shown in Figure 5, the first communication unit can send the transmission configuration information to the wireless access device, so that the wireless access device can subsequently transmit the service data of the communication management service based on the transmission configuration information to ensure the service quality of the data transmission of the communication management service transmitted by the wireless access device.

[0199] As another application example of implementation example 1, when the second communication unit may be a wireless access device (or a module in the wireless access device), as shown in FIG6 , the following steps are included.

[0200] S601. A first communication unit sends transmission configuration information to the wireless access device, wherein the transmission configuration information includes first configuration information and second configuration information, the first configuration information being used to configure QoS for data transmission for the communication management service on the terminal device, and the second configuration information being used to configure QoS for data transmission for the communication management service on the wireless access device.

[0201] S602. The wireless access device sends the first configuration information to the terminal device.

[0202] S603. The service data of the communication management service is transmitted between the wireless access device and the terminal device based on the transmission configuration information, that is, the wireless access device transmits the service data of the communication management service between the wireless access device and the terminal device based on the first configuration information, and the terminal device transmits the service data of the communication management service between the wireless access device and the terminal device based on the second configuration information.

[0203] Specifically, in the implementation process shown in Figure 6, the first communication unit can send transmission configuration information containing first configuration information and second configuration information to the wireless access device, so that the wireless access device can further send the first configuration information to the terminal device. Subsequently, the terminal device and the wireless access device can transmit service data of the communication management service based on the first configuration information and the second configuration information respectively to ensure the service quality of the data transmission of the communication management service transmitted by the wireless access device.

[0204] Implementation example 2: In the technical solution shown in FIG4 , the second communication unit may be a terminal device.

[0205] As an application example of implementation example 2, when the second communication unit may be a terminal device (or a module in the terminal device), as shown in FIG7 , the following steps are included.

[0206] S701. A first communication unit sends transmission configuration information to the terminal device, wherein the transmission configuration information includes at least first configuration information, and the first configuration information is used to configure QoS of data transmission for the communication management service on the terminal device.

[0207] It should be understood that when there is a direct communication link between the first communication unit and the terminal device for communication (for example, the scenario shown in Figure 3d above), in step S701, the first communication unit can send transmission configuration information to the terminal device through the direct communication link. In the case where there is no direct communication link between the first communication unit and the terminal device for communication (for example, the scenario shown in Figure 3a / Figure 3b / Figure 3c / Figure 3e above), in step S701, the first communication unit can send transmission configuration information to the terminal device through forwarding by other devices (such as CU, DU or wireless access device).

[0208] S702. The terminal device transmits the service data of the communication management service based on the transmission configuration information. That is, the terminal device transmits the service data of the communication management service between the wireless access device and the terminal device based on the transmission configuration information.

[0209] Specifically, in the implementation process shown in Figure 7, the first communication unit can send the transmission configuration information to the terminal device, so that the terminal device can subsequently transmit the service data of the communication management service based on the transmission configuration information to ensure the service quality of the data transmission of the communication management service transmitted on this side of the terminal device.

[0210] It should be noted that the implementation process shown in Figures 5 to 7 can refer to the description of Figure 4 and related embodiments above, and achieve corresponding implementation effects, which will not be repeated here.

[0211] As can be seen from the description of Figures 3a to 3e above, the technical solution shown in Figure 4 can be applied to a variety of network architectures. To facilitate understanding of the above implementation process, more implementation examples will be provided below for description. It should be noted that in the examples shown in Figures 8 / 9 / 10 below, the communication management service is used as an AI service for illustration, that is, the communication management service is used to manage, configure, update, and optimize at least one of the communication parameters involved in the wireless access communication service through AI.

[0212] Please refer to Figure 8, which is another schematic diagram of an implementation example of the communication method provided in this application, wherein the example shown in Figure 8 is an application example of the network architecture shown in Figure 3a above. In Figure 8, the first communication unit is a RAN AI entity, and the second communication unit is a terminal device, CU or DU as an example.

[0213] It should be noted that in the implementation process shown in Figure 8 below, when the second communication unit is a CU, step 4 is an example implementation of step S301 above, i.e., the RAN AI entity can send transmission configuration information to the DU through step 4; when the second communication unit is a DU, steps 4 and 6 are examples of an implementation of step S301 above, i.e., the RAN AI entity can send transmission configuration information to the DU through steps 4 and 6; when the second communication unit is a terminal device, steps 4, 6, and 8 are examples of an implementation of step S301 above, i.e., the RAN AI entity can send transmission configuration information to the terminal device through steps 4, 6, and 8. Furthermore, the other steps in Figure 8 are optional.

[0214] In implementation scenario 1, as shown in Figure 8, when the RAN AI entity, CU, DU, or terminal device has AI service data to transmit, it triggers the RAN side to establish a CRB for AI model / data transmission. During the CRB creation process, the RAN AI entity can configure the AI ​​service QoS parameters for the CRB, thereby executing the service process shown in Figure 8, which includes the following steps.

[0215] Step 0: The terminal device sends capability information.

[0216] Exemplarily, the terminal device can report capability information to the RAN network element (such as CU) during the attachment process and the routing area update process. The capability information may include AI capabilities, mobility feature information of the terminal device (i.e., mobility feature description), hardware capabilities of the terminal device (such as computing power, storage space), and other information. Among them, the AI ​​capability may include an identifier or index (Index) of the AI ​​application scenario supported by the terminal device.

[0217] For example, the index of supported AI application scenarios can be used to identify wireless AI service features supported by the terminal device, such as the smart CSI feature. Based on this parameter and the capabilities of the terminal device, the CU selects AI models that can be used for the corresponding scenario (such as convolutional neural networks (CNN), recurrent neural networks (RNN), deep neural networks (DNN) with different numbers of layers, etc.).

[0218] For example, the mobility characteristics of a terminal device can be used to describe its mobility speed, with values ​​ranging from high mobility (e.g., >40 km / h), medium mobility (e.g., 10-40 km / h), and low mobility (e.g., <10 km / h). The RAN AI entity can then use this parameter to determine the latency requirements for AI model / data transmission (i.e., information D mentioned above).

[0219] Step 1: The CU selects an AI model based on the capability information of the terminal device.

[0220] For example, in step 1, the AI ​​model selected by the CU meets the corresponding AI business scenario and matches various capabilities such as the terminal device hardware.

[0221] For example, when selecting an AI model, the CU can consider the model type and complexity (complexity affects the accuracy of the AI ​​model, and more complex AI models require more computing power and storage space for training and inference). Furthermore, it can consider the appropriate AI model type for the specific problem in the AI ​​business scenario. This information is usually statically configured by the equipment manufacturer or dynamically delivered to the RAN network element in advance by the operator.

[0222] Step 2: CU sends a request message to the RAN AI entity through the G1 interface.

[0223] Specifically, in step 2, the CU initiates the AI ​​service QoS configuration process to the RAN AI entity. The CU sends a request message for AI QoS parameters to trigger the QoS parameter configuration process that satisfies the AI ​​service model transmission. The request message may include the attribute description information of the AI ​​model selected by the CU and the mobility characteristics information of the terminal device (i.e., the parameters carried in step 0).

[0224] For example, the AI ​​model attribute description can be used to describe the selected AI model characteristics and transmission requirements, including but not limited to the AI ​​model parameter scale, AI model structural complexity, and the amount of data required for AI model training. This is used to determine the parameter values ​​of AI QoS.

[0225] Step 3: The RAN AI entity determines the transmission configuration information.

[0226] Specifically, the RAN AI entity can determine the specific AI QoS parameters (i.e., transmission configuration information) for the corresponding AI service based on the AI ​​model attributes and terminal device mobility feature information in step 2 and the locally configured AI service QoS configuration policy (similar to the correspondence between multiple AI model attributes, terminal device mobility features, and multiple AI QoS parameters).

[0227] In addition, the transmission configuration information may include at least one of the following: AI service priority, AI service data packet loss rate, AI service data size, and AI service latency. Furthermore, the RAN AI entity may package corresponding AI QoS for RAN network elements and terminal devices, namely, first configuration information (denoted as AI QoS for UE, used by the terminal device to guide the terminal device in parameter configuration and resource allocation QoS parameters) and second configuration information (denoted as AI QoS for RAN, used by the RAN network element to guide the RAN network element in parameter configuration and resource allocation QoS parameters).

[0228] Optionally, the AI ​​QoS for RAN and AI QoS for UE contain different AI QoS parameters. For example, AI QoS for RAN may include at least one of AI service priority, AI service data packet loss rate, AI service data scale, and AI service latency, which is used for CU / DU to configure downlink CRB resources, such as PDCP encryption and decryption algorithm selection, RLC transmission mode selection, RLC / MAC fragmentation mode, PHY allocation of PRB resources, etc. For another example, AI QoS for UE: CRB configuration parameters used for terminal device reporting data, including at least one of priority and data scale parameters (may not include at least one of AI service data packet loss rate and AI service latency).

[0229] Step 4: After the RAN AI entity completes the AI ​​QoS parameter configuration, it sends the transmission configuration information to the CU through the G1 interface.

[0230] Optionally, the transmission configuration information can be carried in the response message corresponding to the request information in step 2, and carry AI QoS for RAN and AI QoS for UE.

[0231] It should be understood that step 2 and step 4 may be new messages on the G1 interface. The message name is only a naming method and may also be other message types or other message names on the G1 interface, which is not limited here.

[0232] Step 5: The CU establishes a CRB based on the transmission configuration information.

[0233] Specifically, after receiving the configuration parameters from the RAN AI entity, the CU determines, based on AI QoS for RAN, whether there is an established CRB that meets the parameter requirements of AI QoS for RAN (i.e., the AI ​​QoS parameters of the established CRB are the same as those in AI QoS for RAN). If so, the existing CRB is reused; otherwise, a new CRB is created and QoS configuration is performed according to AI QoS for RAN. The CU can configure parameters for the PDCP CRB based on the AI ​​QoS for RAN parameters.

[0234] Step 6: The CU sends transmission configuration information to the DU. That is, the CU sends AI QoS for RAN and AI QoS for UE to the DU.

[0235] Exemplarily, the CU may send AI QoS for RAN and AI QoS for UE to the DU via a downlink radio resource control message transfer (DL RRC message transfer) message of the F1 interface.

[0236] Step 7: DU performs configuration based on the transmission configuration information.

[0237] Exemplarily, the DU configures QoS parameters for the RLC / MAC / PHY layer according to the AI ​​QoS for RAN, and the CU configures parameters for the PDCP CRB according to the AI ​​QoS for RAN parameters.

[0238] Step 8: The DU sends the first configuration information, namely, AI QoS for UE, to the terminal device.

[0239] Exemplarily, the DU may send the AI ​​QoS for UE to the terminal device via an RRC Reconfiguration message of the wireless air interface Uu interface.

[0240] Step 9: The terminal device performs configuration based on the first configuration information (i.e., AI QoS for UE).

[0241] Exemplarily, the terminal device can configure the QoS parameters of the peer protocol layer (including SDAP / PDCP / RLC / MAC / PHY protocol layer) of the terminal device layer according to AI QoS for UE.

[0242] Step 10: The terminal device sends an indication message to the DU, which indicates that the AI ​​QoS for UE configuration on the terminal device is successful.

[0243] Exemplarily, after completing the configuration of relevant parameters, the terminal device replies with a radio resource control reconfiguration complete (RRC Reconfiguration complete) message to the DU, where the message carries an indication of successful configuration.

[0244] Step 11: The DU sends an indication message to the CU, where the indication message is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful and / or the indication message is used to indicate that the AI ​​QoS for RAN configuration on the DU is successful.

[0245] Exemplarily, the DU receives a response from the terminal device in step 10, and after completing the relevant parameter configuration locally, the DU replies to the CU via the F1 interface with an uplink radio resource control message transfer (UL RRC message transfer message), which carries a configuration success indication.

[0246] After that, AI data can be transmitted between the wireless access device and the terminal device based on the corresponding configurations of AI QoS for RAN and AI QoS for UE.

[0247] Therefore, based on the implementation process of the above implementation scenario 1, the RAN AI entity can determine the QoS parameter configuration for AI service transmission based on the actual needs of the AI ​​service, and guide the wireless access device and terminal equipment to reasonably allocate wireless resources, ensuring AI service transmission while also improving the utilization of wireless network resources.

[0248] Implementation scenario two, in Figure 8, when the RAN AI entity version is upgraded or the terminal device version is upgraded (for example, changes are made to the terminal device capabilities or supported AI application scenarios) or the current AI model performance degrades, the terminal device may request a higher-precision AI model and request the network to update the AI ​​model. This requires modifying the current CRB's AI QoS parameters. In the CRB's AI QoS parameter modification process, the RAN AI entity can update (or reconfigure) the CRB's AI service QoS parameter configuration, thereby executing the service process shown in Figure 8, which includes the following steps.

[0249] Step 0: The terminal device sends updated capability information (or changed capability information).

[0250] For example, when the terminal device capability changes or the performance requirements for the AI ​​service change, which may cause the QoS of the original AI service to change, the terminal device can send the change information to the RAN network element (such as CU) for judgment and decision in step 0.

[0251] Optionally, the terminal device can send the changed information to the CU through the enhanced radio access network basic notification area update (RAN-based notification arer update, RNA update) process, including the terminal device's ability to send changed information or the identification index of the changed AI application scenario.

[0252] Step 1: The CU selects an AI model based on the updated capability information of the terminal device.

[0253] For example, the CU can select an AI model that meets the corresponding AI business scenario and matches the terminal device hardware and other capabilities based on the updated capability information of the terminal device, and trigger the QoS parameter modification process that meets the transmission of the AI ​​business model in step 2.

[0254] Step 2: CU sends a request message to the RAN AI entity through the G1 interface.

[0255] Exemplarily, the CU initiates an AI service QoS modification process to the RAN AI entity via the G1 interface. This involves sending an AI QoS parameter modification request, including information such as the attribute description of the AI ​​model selected by the CU and the mobility characteristics of the terminal device, to the RAN AI entity. For explanations of the relevant parameters, refer to the description of the preceding embodiment.

[0256] Step 3: The RAN AI entity determines the transmission configuration information.

[0257] Exemplarily, the RAN AI entity determines specific AI QoS parameters for the corresponding AI service based on the AI ​​model attributes from step 2, the mobility characteristics of the terminal device, and the locally configured AI service QoS configuration policy, including at least one of AI service priority, AI service data packet loss rate, AI service data size, and AI service latency. The RAN AI entity then packages the corresponding AI QoS for the RAN network element and the terminal device. For explanations of the relevant parameters, refer to the description of the above embodiment.

[0258] Step 4: After the RAN AI entity completes the AI ​​QoS parameter configuration, it sends the transmission configuration information to the RAN network element through the G1 interface.

[0259] Optionally, the transmission configuration information may be carried in the response message corresponding to the request information in step 2, and may include the modified AI QoS for RAN and AI QoS for UE. For details about AI QoS for RAN and AI QoS for UE, refer to the description of the above embodiment.

[0260] Step 5: CU performs update based on the transmission configuration information.

[0261] Exemplarily, after receiving the modified parameters from the RAN AI entity, the CU performs QoS update according to the modified AI QoS for RAN, and the CU updates parameters for the PDCP CRB according to the modified AI QoS for RAN parameters.

[0262] Step 6: The CU sends transmission configuration information to the DU. That is, the CU sends AI QoS for RAN and AI QoS for UE to the DU.

[0263] Exemplarily, the CU sends the modified AI QoS for RAN and AI QoS for UE to the DU network element through the DL RRC message transfer message of the F1 interface.

[0264] Step 7: DU performs configuration based on the transmission configuration information.

[0265] Exemplarily, the DU updates the QoS parameters of the RLC / MAC / PHY layer according to the modified AI QoS for RAN, and the CU updates the parameters for the PDCP CRB according to the modified AI QoS for RAN parameters.

[0266] Step 8. The DU sends the first configuration information (i.e., AI QoS for UE) to the terminal device.

[0267] Exemplarily, the DU sends the modified AI QoS for UE to the terminal device through the RRC Reconfiguration message of the wireless air interface Uu interface.

[0268] Step 9: The terminal device performs configuration based on the first configuration information (i.e., AI QoS for UE).

[0269] Exemplarily, the terminal device updates the QoS parameters of the peer protocol layer (including SDAP / PDCP / RLC / MAC / PHY protocol layer) of the terminal device layer according to the modified AI QoS for UE.

[0270] Step 10: The terminal device sends an indication message to the DU, which indicates that the AI ​​QoS for UE configuration on the terminal device is successful.

[0271] Exemplarily, after completing the relevant parameter update, the terminal device replies with an RRC Reconfiguration complete message to the DU, where the message carries an indication of successful configuration.

[0272] Step 11: The DU sends an indication message to the CU, where the indication message is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful and / or the indication message is used to indicate that the AI ​​QoS for RAN configuration on the DU is successful.

[0273] For example, after the DU receives a response from the terminal device and completes the update of relevant parameters itself, it replies with a UL RRC message transfer message to the CU through the F1 interface, and the message carries an indication of successful configuration.

[0274] After that, AI data can be transmitted between the wireless access device and the terminal device based on the corresponding configurations of AI QoS for RAN and AI QoS for UE.

[0275] By implementing scenario 2, the RAN AI entity can promptly update and refresh AI service requirements based on the updated capabilities and requirements of terminal devices, and then promptly adjust the QoS parameters for AI service transmission to ensure the rational use of RAN resources.

[0276] Please refer to Figure 9, which is another schematic diagram of an implementation example of the communication method provided in this application, wherein the example shown in Figure 9 is an application example of the network architecture shown in Figure 3b above. In Figure 9, the first communication unit is a Near-RT RIC, and the second communication unit is a terminal device, CU or DU as an example for illustration.

[0277] It should be noted that in the implementation process shown in Figure 9 below, when the second communication unit is a CU, step 4 is an implementation example of step S301 above, that is, the Near-RT RIC can send transmission configuration information to the DU through step 4; when the second communication unit is a DU, steps 4 and 6 are an implementation example of step S301 above, that is, the Near-RT RIC can send transmission configuration information to the DU through steps 4 and 6; when the second communication unit is a terminal device, steps 4, 6, and 8 are an implementation example of step S301 above, that is, the Near-RT RIC can send transmission configuration information to the terminal device through steps 4, 6, and 8. In addition, the other steps in Figure 9 are optional steps.

[0278] In implementation scenario three, in Figure 9, when the Near-RT RIC, CU, DU, or terminal device has AI service data to transmit, it triggers the RAN side to establish a CRB for AI model / data transmission. During the CRB creation process, the Near-RT RIC can configure the AI ​​service QoS parameters for the CRB, thereby executing the service process shown in Figure 8, including the following steps.

[0279] It should be noted that the implementation process for Scenario 3 is similar to that for Scenario 1, differing only in the network architecture used. In Scenario 3, AI service QoS parameter management is performed by the Near-RT RIC. This means that the RAN AI entity in Scenario 1 is replaced with the Near-RT RIC. Accordingly, the G1 interface between the RAN AI entity and the CU is replaced with the E2 interface between the Near-RT RIC and the CU.

[0280] Step 0: The terminal device sends capability information.

[0281] Step 1: The CU selects an AI model based on the capability information of the terminal device.

[0282] The implementation process of step 0 and step 1 can refer to the implementation process of step 0 and step 1 in the implementation scenario 1 above.

[0283] Step 2: The CU sends a request message to the Near-RT RIC through the E2 interface.

[0284] Specifically, in step 2, the CU initiates the AI ​​service QoS configuration process to the Near-RT RIC via the E2 interface. Specifically, the CU sends a request message for AI QoS parameters to trigger the QoS parameter configuration process that satisfies the AI ​​service model transmission. This request message may include the attribute description information of the AI ​​model selected by the CU and the terminal device mobility characteristics information (the parameters carried in step 0).

[0285] Step 3: Near-RT RIC determines the transmission configuration information.

[0286] Specifically, the Near-RT RIC determines AI QoS parameters for the corresponding AI service based on the AI ​​model attributes and terminal device mobility characteristics from step 2, as well as the locally configured AI service QoS configuration policy. These parameters include AI service priority, AI service data packet loss rate, AI service data size, and AI service latency. The Near-RT RIC then packages the corresponding AI QoS for the RAN network element and terminal device.

[0287] Step 4: After the Near-RT RIC completes the AI ​​QoS parameter configuration, it sends the transmission configuration information to the CU through the G1 interface.

[0288] Optionally, the transmission configuration information is a response message corresponding to the request information in step 2, and carries AI QoS for RAN and AI QoS for UE.

[0289] It should be understood that step 2 and step 4 may be new messages on the E2 interface. The message name is only a naming method and may also be other message types or other message names on the E2 interface, which is not limited here.

[0290] Step 5: The CU establishes a CRB based on the transmission configuration information.

[0291] Step 6: The CU sends transmission configuration information to the DU. That is, the CU sends AI QoS for RAN and AI QoS for UE to the DU.

[0292] Step 7: DU performs configuration based on the transmission configuration information.

[0293] Step 8. The DU sends the first configuration information (i.e., AI QoS for UE) to the terminal device.

[0294] Step 9: The terminal device performs configuration based on the first configuration information (i.e., AI QoS for UE).

[0295] Step 10: The terminal device sends an indication message to the DU, which indicates that the AI ​​QoS for UE configuration on the terminal device is successful.

[0296] Step 11: The DU sends an indication message to the CU, where the indication message is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful and / or the indication message is used to indicate that the AI ​​QoS for RAN configuration on the DU is successful.

[0297] The implementation process of steps 5 to 11 may refer to the implementation process of steps 5 to 11 in the above implementation scenario 1.

[0298] After that, AI data can be transmitted between the wireless access device and the terminal device based on the corresponding configurations of AI QoS for RAN and AI QoS for UE.

[0299] Therefore, based on the implementation process of the above implementation scenario three, Near-RT RIC can determine the QoS parameter configuration for AI service transmission based on the actual needs of AI services, and guide wireless access devices and terminal devices to reasonably allocate wireless resources, ensuring AI service transmission while also improving the utilization of wireless network resources.

[0300] Implementation scenario four. In Figure 9, when the Near-RT RIC version is upgraded or the terminal device version is upgraded (such as changes in the terminal device capabilities or supported AI application scenarios) or the current AI model performance degrades, the terminal device may request a higher-precision AI model and request the network to update the AI ​​model. In this case, the AI ​​QoS parameters of the current CRB need to be modified. In the AI ​​QoS parameter modification process of the CRB, the Near-RT RIC can perform an update (or reconfiguration) of the AI ​​service QoS parameter configuration of the CRB, thereby executing the service process shown in Figure 9, including the following steps.

[0301] It should be noted that the implementation process for Scenario 4 is similar to that for Scenario 2, differing only in the network architecture used. In Scenario 4, AI service QoS parameter management is performed by the Near-RT RIC. This means that the RAN AI entity in Scenario 2 is replaced with the Near-RT RIC. Accordingly, the G1 interface between the RAN AI entity and the CU is replaced with the E2 interface between the Near-RT RIC and the CU.

[0302] Step 0: The terminal device sends updated capability information (or changed capability information).

[0303] Step 1: The CU selects an AI model based on the updated capability information of the terminal device.

[0304] The implementation process of step 0 and step 1 can refer to the implementation process of step 0 and step 1 in the previous implementation scenario 2.

[0305] Step 2: The CU sends a request message to the Near-RT RIC through the G1 interface.

[0306] Exemplarily, the CU initiates an AI service QoS modification process to the Near-RT RIC through the E2 interface, i.e., sends an AI QoS parameter modification request, and sends the attribute description information of the AI ​​model selected by the CU and the terminal device mobility feature information to the Near-RT RIC.

[0307] Step 3: The Near-RT RIC determines the transmission configuration information.

[0308] For example, the Near-RT RIC determines specific AI QoS parameters for the corresponding AI service based on the AI ​​model attributes and terminal device mobility characteristics from step 2, as well as the locally configured AI service QoS configuration policy. These parameters include AI service priority, AI service data packet loss rate, AI service data size, and AI service latency. The Near-RT RIC then packages the corresponding AI QoS for the RAN network element and terminal device.

[0309] Step 4: After the Near-RT RIC completes the AI ​​QoS parameter configuration, it sends the transmission configuration information to the RAN network element through the E2 interface.

[0310] Exemplarily, after the Near-RT RIC function completes the AI ​​QoS parameter modification, it returns the specific modified parameters to the CU through the E2 interface, that is, it replies to the request message / AI QoS parameter response message in step 2 and carries the modified AI QoS for RAN and AI QoS for UE.

[0311] Step 5: The CU establishes a CRB based on the transmission configuration information.

[0312] Step 6: The CU sends transmission configuration information to the DU. That is, the CU sends AI QoS for RAN and AI QoS for UE to the DU.

[0313] Step 7: DU performs configuration based on the transmission configuration information.

[0314] Step 8. The DU sends the first configuration information (i.e., AI QoS for UE) to the terminal device.

[0315] Step 9: The terminal device performs configuration based on the first configuration information (i.e., AI QoS for UE).

[0316] Step 10: The terminal device sends an indication message to the DU, which indicates that the AI ​​QoS for UE configuration on the terminal device is successful.

[0317] Step 11: The DU sends an indication message to the CU, where the indication message is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful and / or the indication message is used to indicate that the AI ​​QoS for RAN configuration on the DU is successful.

[0318] The implementation process of steps 5 to 11 may refer to the implementation process of steps 5 to 11 in the above implementation scenario 2.

[0319] After that, AI data can be transmitted between the wireless access device and the terminal device based on the corresponding configurations of AI QoS for RAN and AI QoS for UE.

[0320] Therefore, based on the implementation process of the above-mentioned implementation scenario 4, the Near-RT RIC can timely update and refresh the needs of AI services according to the updated capabilities and requirements of the terminal equipment, and then promptly adjust the QoS parameters of AI service transmission to ensure the rational use of RAN resources.

[0321] Please refer to Figure 10, which is another schematic diagram of an implementation example of the communication method provided in this application, wherein the example shown in Figure 10 is an application example of the network architecture shown in Figure 3c above. In Figure 9, the first communication unit is an internal module of the CU, and the second communication unit is a terminal device or DU.

[0322] It should be noted that in the implementation process shown in Figure 10 below, when the second communication unit is a DU, step 4 is an example implementation of step S301 above, that is, the first communication unit can send transmission configuration information to the DU through step 4; when the second communication unit is a terminal device, steps 4 and 6 are examples implementation of step S301 above, that is, the first communication unit can send transmission configuration information to the terminal device through steps 4 and 6. In addition, the other steps in Figure 10 are optional steps.

[0323] Implementation scenario five. In Figure 10, when the first communication unit or CU or DU or terminal device has AI service data to be transmitted, it triggers the RAN side to establish a CRB for AI model / data transmission. Then, during the CRB creation process, the first communication unit can perform AI service QoS parameter configuration on the CRB, thereby executing the service process shown in Figure 10, including the following steps.

[0324] Step 0: The terminal device sends capability information.

[0325] Step 1: The CU selects an AI model based on the capability information of the terminal device.

[0326] The implementation process of step 0 and step 1 can refer to the implementation process of step 0 and step 1 in the implementation scenario 1 above.

[0327] Step 2: The first communication unit located inside the CU determines transmission configuration information.

[0328] Specifically, the first communication unit determines AI QoS parameters for the corresponding AI service based on the AI ​​model attributes and terminal device mobility characteristics from step 1, as well as the locally configured AI service QoS configuration policy. These parameters include AI service priority, AI service data packet loss rate, AI service data size, and AI service latency. The first communication unit then packages the corresponding AI QoS for the DU and terminal device.

[0329] Step 3: The CU establishes a CRB based on the transmission configuration information.

[0330] Specifically, based on the transmission configuration information determined by the first communication unit, the CU determines according to AI QoS for RAN whether there is an established CRB that can meet the parameter requirements of AI QoS for RAN (that is, the AI ​​QoS parameters of the established CRB are the same as the parameters in AI QoS for RAN). If so, the existing CRB is reused; otherwise, a new CRB is created and QoS configuration is performed according to AI QoS for RAN. The CU can configure parameters for the PDCP CRB according to the AI ​​QoS for RAN parameters.

[0331] Step 4: The CU sends transmission configuration information to the DU. That is, the CU sends AI QoS for RAN and AI QoS for UE to the DU.

[0332] Step 5: DU performs configuration based on the transmission configuration information.

[0333] Step 6: The DU sends the first configuration information (i.e., AI QoS for UE) to the terminal device.

[0334] Step 7: The terminal device performs configuration based on the first configuration information (i.e., AI QoS for UE).

[0335] Step 8. The terminal device sends an indication message to the DU, which is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful.

[0336] Step 9: The DU sends an indication message to the CU, where the indication message is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful and / or the indication message is used to indicate that the AI ​​QoS for RAN configuration on the DU is successful.

[0337] After that, AI data can be transmitted between the wireless access device and the terminal device based on the corresponding configurations of AI QoS for RAN and AI QoS for UE.

[0338] The implementation process of steps 4 to 9 may refer to the implementation process of steps 6 to 11 in the above implementation scenario 1.

[0339] Therefore, based on the implementation process of the above-mentioned implementation scenario five, the first communication unit located inside the CU can determine the QoS parameter configuration of AI service transmission based on the actual needs of the AI ​​service, and guide the wireless access device and terminal device to reasonably allocate wireless resources, ensuring the transmission of AI services while also improving the utilization of wireless network resources.

[0340] Implementation scenario six. In Figure 10, when the version of the first communication unit located inside the CU is upgraded or the terminal device version is upgraded (such as changes in the terminal device capabilities or supported AI application scenarios) or the current AI model performance degrades, the terminal device may request a higher-precision AI model and request the network to update the AI ​​model. In this case, the AI ​​QoS parameters of the current CRB need to be modified. In the AI ​​QoS parameter modification process of the CRB, the Near-RT RIC can execute an update (or reconfiguration) of the AI ​​service QoS parameter configuration of the CRB, thereby executing the business process shown in Figure 10, including the following steps.

[0341] It should be noted that the execution process for Scenario 6 is similar to that for Scenario 2, differing only in the network architecture used. In Scenario 6, AI service QoS parameter management is performed by the first communication unit within the CU. This replaces the RAN AI entity in Scenario 2 with the first communication unit within the CU.

[0342] Step 0: The terminal device sends updated capability information (or changed capability information).

[0343] Step 1: The CU selects an AI model based on the updated capability information of the terminal device.

[0344] The implementation process of step 0 and step 1 can refer to the implementation process of step 0 and step 1 in the previous implementation scenario 2.

[0345] Step 2: The first communication unit located inside the CU determines transmission configuration information.

[0346] Specifically, the first communication unit determines AI QoS parameters for the corresponding AI service based on the AI ​​model attributes and terminal device mobility characteristics from step 1, as well as the locally configured AI service QoS configuration policy. These parameters include AI service priority, AI service data packet loss rate, AI service data size, and AI service latency. The first communication unit then packages the corresponding AI QoS for the DU and terminal device.

[0347] Step 3: The CU establishes a CRB based on the transmission configuration information.

[0348] Specifically, based on the transmission configuration information determined by the first communication unit, the CU determines according to AI QoS for RAN whether there is an established CRB that can meet the parameter requirements of AI QoS for RAN (that is, the AI ​​QoS parameters of the established CRB are the same as the parameters in AI QoS for RAN). If so, the existing CRB is reused; otherwise, a new CRB is created and QoS configuration is performed according to AI QoS for RAN. The CU can configure parameters for the PDCP CRB according to the AI ​​QoS for RAN parameters.

[0349] Step 4: The CU sends transmission configuration information to the DU. That is, the CU sends AI QoS for RAN and AI QoS for UE to the DU.

[0350] Step 5: DU performs configuration based on the transmission configuration information.

[0351] Step 6: The DU sends the first configuration information (i.e., AI QoS for UE) to the terminal device.

[0352] Step 7: The terminal device performs configuration based on the first configuration information (i.e., AI QoS for UE).

[0353] Step 8. The terminal device sends an indication message to the DU, which is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful.

[0354] Step 9: The DU sends an indication message to the CU, where the indication message is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful and / or the indication message is used to indicate that the AI ​​QoS for RAN configuration on the DU is successful.

[0355] After that, AI data can be transmitted between the wireless access device and the terminal device based on the corresponding configurations of AI QoS for RAN and AI QoS for UE.

[0356] The implementation process of steps 4 to 9 may refer to the implementation process of steps 6 to 11 in the above implementation scenario 1.

[0357] Therefore, based on the implementation process of the above-mentioned implementation scenario five, the first communication unit located inside the CU can timely update and refresh the needs of the AI ​​service according to the latest capabilities and requirements of the terminal device, and then timely adjust the QoS parameters of the AI ​​service transmission to ensure the rational use of RAN resources.
