Technical Field

[0001] The present application relates to the field of wireless technology, and in particular to a communication method, related equipment and system. Background Art

[0002] Wireless communication can be the transmission communication between two or more communication nodes without propagation through conductors or cables. The communication nodes generally include terminal devices and wireless access devices.

[0003] At present, in a wireless communication system, a wireless access device can calculate and determine the transmission resources of a signal, for example, the transmission resources may include time domain resources and frequency domain resources for carrying the signal. Accordingly, the terminal device can send and receive signals on the transmission resources. In this way, the wireless access device can provide a wireless access communication service for network access for at least one terminal device.

[0004] 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 service itself is a technical problem that needs to be solved urgently. Summary of the invention

[0005] 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.

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, and the transmission configuration information is used to configure the quality of service (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 the 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.

Among them, the transmission configuration information sent by the first communication unit is used to configure the QoS of data transmission of the service data of the communication management service between the terminal device and the wireless access device. After that, the recipient of the transmission configuration information can subsequently transmit the service data of the communication management service based on the transmission configuration information. Therefore, in the above technical solution, while the wireless access communication service is managed by the communication management service to improve the service quality of network access, 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] 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.

[0104] First, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0105] (1) Configuration and pre-configuration: In this application, configuration and pre-configuration will be used at the same time. Configuration refers to the base station or server and other network devices 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 method in which a base station or server and other network devices send parameter information or values ​​to the terminal through a communication link or carrier; it can also be a definition of corresponding parameters or parameter values ​​given 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.

[0106] (2) In this application, "used for indication" may include being used for direct indication and being used for indirect indication. When describing that a certain indication information is used for indicating A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0107] 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, specified by the protocol), thereby reducing the indication overhead to a certain extent.

[0108] 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 pre-defined, for example, pre-defined according to the protocol, or can be configured by the transmitting device by sending configuration information to the receiving device. Among them, the configuration information can include, for example but not limited to, 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 medium access control control element (MAC CE); physical layer signaling, for example, includes downlink control information (DCI).

[0109] (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 "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural.

[0111] See also Figure 1 , is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. Figure 1 As shown, the communication system includes a radio access network (RAN) 100 and a core network 200.

[0112] Optionally, the communication system 1000 may also include the Internet 300 .

[0113] exist Figure 1 In the example, RAN 100 includes at least one RAN node (e.g. Figure 1 110a and 110b in the figure, collectively referred to as 110), and may also include at least one terminal (such as Figure 1 120a-120j in the figure are collectively referred to as 120). The RAN node may also be referred to as a wireless access device, a network device, an access network device, etc.

[0114] exist Figure 1 In the example, RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment ( Figure 1(not shown in the figure). The terminal 120 is connected to the RAN node 110 by wireless means, and the RAN node 110 is connected to the core network 200 by wireless or wired means. The core network device in the core network 200 and the RAN node 110 in the RAN 100 may be independent and different physical devices, or may be the same physical device that integrates the logical functions of the core network device and the logical functions of the RAN node. Terminals and terminals and RAN nodes and RAN nodes may be connected to each other by wired or wireless means.

[0115] RAN100 may be an evolved universal terrestrial radio access (E-UTRA) system, a new radio (NR) system, and a future radio access system defined in the 3rd generation partnership project (3GPP). RAN100 may also include two or more of the above-mentioned different radio access systems. RAN100 may also be an open RAN (O-RAN).

[0116] RAN node, also known as radio access network equipment, RAN entity or access node, is used to help terminals access the communication system wirelessly. In one application scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in the fifth generation (5G) mobile communication system, a next generation NodeB in the sixth generation (6G) mobile communication system, or a base station in a future mobile communication system. RAN nodes can be macro base stations (such as Figure 1 110a), or a micro base station or an indoor station (such as Figure 1 110b) in the figure, it can also be a relay node or a donor node.

[0117] In another application scenario, the cooperation of multiple RAN nodes can be used to help the terminal achieve wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU) or a radio unit (RU). The CU here completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the MAC layer of the base station, and can also complete the functions of part of the physical layer or all of the physical layer. For the specific description of the above-mentioned various protocol layers, please refer to the relevant technical specifications of 3GPP. RU can be used to implement the transceiver function of radio frequency signals. CU and DU can be two independent RAN nodes, or they can be integrated in the same RAN node, such as integrated in a baseband unit (BBU). RU can be included in a radio frequency device, 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.

[0118] 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 takes CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit in the 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.

[0119] 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.

[0123] The embodiments of the present application do not limit the specific technology and specific device form adopted by the RAN node. For the convenience of description, the following description takes a base station as an example of a RAN node.

[0124] A terminal is a device with wireless transceiver function, which can send signals to a base station or receive signals from a base station. A terminal can also be called a terminal device, user equipment (UE), a mobile station, a mobile terminal, etc. The terminal can be widely used in various scenarios, for example, device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, automatic driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal.

[0125] Base stations and terminals can be fixed or movable. Base stations and terminals can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on airplanes, balloons, and artificial satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.

[0126] The roles of the base station and the terminal can be relative, for example, Figure 1 The helicopter or drone 120i in the figure can be configured as a mobile base station. For the terminal 120j that accesses the wireless access network 100 through 120i, the terminal 120i is a base station; but for the base station 110a, 120i is a terminal, that is, 110a and 120i communicate through the wireless air interface protocol. Of course, 110a and 120i can also communicate through the interface protocol between base stations. In this case, relative to 110a, 120i is also a base station. Therefore, base stations and terminals can be collectively referred to as communication devices. Figure 1 110a and 110b in the figure may be referred to as communication devices having base station functions. Figure 1 120a-120j in the figure can be called communication devices with terminal functions.

[0127] Base stations and terminals, base stations and base stations, and terminals and terminals can communicate through authorized spectrum, unauthorized spectrum, or both; they can communicate 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.

[0128] In this application, the functions of the base station can also be performed by a module (such as a chip) in the base station, or by a control subsystem that includes the base station function. The control subsystem that includes the base station function here can be a 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 (such as a chip or a modem) in the terminal, or by a device that includes the terminal function.

[0129] In a wireless communication system, a wireless access device can calculate and determine the transmission resources of a signal. For example, the transmission resources may include time domain resources and frequency domain resources for carrying the signal. Accordingly, the terminal device can send and receive signals on the transmission resources. In this way, the wireless access device can provide the terminal device with a communication service for network access.

[0130] However, in communication networks, how to improve data transmission performance is a technical problem that needs to be solved urgently.

[0131] In a possible implementation, the communication management service implemented by intelligent technology can intelligently manage (including optimization / configuration / update, etc.) the communication service that provides network access to improve data transmission performance. The intelligent technology may include artificial intelligence technology, neural network technology, machine learning technology, etc.

[0132] Exemplarily, taking the AI ​​method as an example, the intelligent method can be implemented through wireless scenarios such as AI-enabled beam management and AI-enabled CSI feedback 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.

[0133] In an implementation example, unilateral AI can be to deploy an AI model on one side of a terminal device or a wireless access device for a certain wireless service feature.

[0134] For example, Figure 2a As shown, 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 (for example, Figure 2a The AI ​​inference shown); thereafter, in step A3, the terminal device may send the result of the AI ​​inference to the wireless access device via an RRC message, and the specific RRC message type is not limited in this article.

[0135] For example, Figure 2b As shown, 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, Figure 2b Thereafter, in step B3, the wireless access device may send the result of the AI ​​inference to the terminal device via an RRC message.

[0136] In another implementation example, bilateral AI is to deploy AI models on both the terminal device and the wireless access device for a certain wireless service feature. Figure 2c As shown, 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 (for example, Figure 2cThe terminal device may perform AI inference in step C4, and in step C5, the wireless access device may send the result of AI inference to the terminal device via an RRC message.

[0137] In addition, AI models applied to wireless air interfaces (such as Figure 2a or Figure 2c AI models deployed on terminal devices, or Figure 2b or Figure 2c The AI ​​model deployed in the wireless access device is generally generated based on the training of wireless network data 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 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 with new wireless network data to obtain a new AI model with accuracy that meets the requirements.

[0138] Generally, due to the limited computing power, storage space, battery power and other resource capabilities 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, and 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 service data (such as AI model, AI model training data (hereinafter referred to as AI data)) on the wireless air interface has the following characteristics: the amount of transmitted AI service data is large, and the AI ​​service data comes from the terminal device or the wireless access device.

[0139] 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 the transmission of AI data. In order to support the interaction of AI data between terminal devices and wireless access devices, such as Figure 2d As shown, in addition to DRB and SRB, AI data can be transmitted between terminal devices and wireless access devices through computing radio bearers (CRB). Among them, CRB between terminal devices and network devices can be transmitted through data analysis protocol (DAP). For example, CRB and DAP can be new wireless bearer types and control management protocols proposed for data transmission of communication management services (which can have RAN-AI model / data distribution, security (including integrity protection, encryption and decryption) and other functions).

[0140] However, due to the large amount of data transmission of AI data (such as AI model data, data required for AI model training, etc.) (usually megabyte (MB), gigabyte (GB), or even terabyte (TB) level), more wireless air interface resources are required. At present, no relevant implementation plan has been provided 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, the transmission of AI data may fail.

[0141] To this end, when the communication management service implemented by intelligent technology performs intelligent management (such as optimization / configuration / update) on the communication service that provides network access to improve data transmission performance, how to manage the transmission performance of the communication management service itself is a technical problem that needs to be solved urgently.

[0142] In order to solve the above problems, the present application provides a communication method, related equipment and system, which are used to manage the wireless access communication service through the communication management service to improve the service quality of network access, and 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 the data transmission performance. The following will be described in detail with reference to the accompanying drawings.

[0143] The following will be combined Figure 3a / Figure 3b / Figure 3c / Figure 3d / Figure 3e The example shown exemplifies the network architecture applied to the communication method provided in this application. In the following example, the first communication unit may be a new logical functional entity introduced for intelligent scenarios (such as AI application scenarios), responsible for AI model training, deployment, performance monitoring, AI data processing and other AI-related functions. 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.

[0144] Optionally, in Figure 3a / Figure 3b / Figure 3c / Figure 3d / Figure 3e In the example shown, 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.

[0145] exist Figure 3a In the embodiment, the wireless access device may include a CU and a DU, and the first communication unit mentioned below may be a module in the wireless access device that is independent of the CU and the DU, wherein 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, Figure 3a In the illustrated architecture, 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 may be deployed in combination with a CU, but is independent of the CU in terms of logical functions.

[0146] It should be understood that Figure 3aIn the present invention, 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.

[0147] exist Figure 3b In the embodiment, the wireless access device may include a CU and a DU, and the first communication unit mentioned below may be a module independent of the wireless access device, wherein the first communication unit may communicate with the wireless access device through an E2 interface. Figure 3b In the architecture shown, 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 can add an AIQoS management function module to support the management of QoS of service transmission of communication management services (including optimization / configuration / update). In addition, Figure 3b The shown architecture can be applied to an open RAN scenario. For example, the first communication unit can be a radio access network near real-time intelligent controller (Near-RT RIC) functional entity, or the first communication unit can be a basic platform function component (platform function module) of Near-RT RIC, etc.

[0148] It should be understood that Figure 3b In the present invention, 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.

[0149] exist Figure 3c In the present invention, the wireless access device may include a CU and a DU, and the first communication unit mentioned later may be a module built into the CU, wherein the first communication unit may communicate with the DU through the F1 interface. In other words, by enhancing the CU function, that is, adding an AIQoS management function module to support the management of the QoS of the service transmission of the communication management service (including optimization / configuration / update), and enhancing the F1 interface between the CU and the DU, the interaction of the transmission configuration information mentioned later is supported.

[0150] It should be understood that Figure 3c In the embodiment, 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.

[0151] Optionally, in the above Figure 3a to Figure 3c In the embodiment, the scenario of separation of CU and DU in the wireless access network is taken as an example. However, in actual applications, the wireless access network can also be implemented in other ways.

[0152] For example, compared to Figure 3a and Figure 3c The architecture shown in Figure 3d In the wireless access device, the CU and DU may not be distinguished, that is, the first communication unit may be a logical module / physical module in the wireless access device. Figure 3d In the present invention, 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.

[0153] For example, compared to Figure 3b The architecture shown in Figure 3e In the wireless access device, the CU and DU may not be distinguished, that is, the first communication unit may be a logical module / physical module independent of the wireless access device. Figure 3e In the present invention, the wireless access device or the terminal device may serve as the second communication unit, that is, 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 a module in the terminal device.

[0154] It should be understood that the second communication unit mentioned below can be Figures 3a to 3e The specific implementation process of any one of the wireless access device, terminal device, CU or DU in the illustrated architecture is detailed in the description of the embodiments below.

[0155] See also Figure 4 , is a schematic diagram of the communication method provided in this application, and the method includes the following steps.

[0156] It should be noted that Figure 4 The method is illustrated by taking the first communication unit and the second communication unit as the execution subjects of the interaction as an example. The first communication unit and the second communication unit can be Figures 3a to 3e The first communication unit and the second communication unit in any of the figures, for example, the first communication unit may be an internal module of the wireless access device, or may be a device / module independent of the wireless access device. For another example, the second communication unit may be a wireless access device, a CU, a DU, or a terminal device, or may be a module in the wireless access device, a module in the CU, a module in the DU, or a module in the terminal device.

[0157] It should be understood that Figure 4In the embodiment, 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. 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, a chip or a chip system, etc.), or the second communication unit may be a logic module or software that implements all or part of the functions of the communication device.

[0158] Optionally, execute Figures 4 to 10 The first communication unit (or wireless access device, or CU, or DU) of the method shown may 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.

[0159] S401. The first communication unit sends transmission configuration information, and the second communication unit receives the transmission configuration information accordingly. The transmission configuration information is used to configure the quality of service (QoS) of data transmission, and 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.

[0160] It should be understood that the communication management service is used to manage the wireless access communication service, which can be understood as 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), and the intelligent manner may include artificial intelligence (artificial), neural network, machine learning and other technology-enabled methods. In other words, the communication management service can be a service that improves the service quality of the wireless access communication service based on an intelligent manner. Accordingly, the communication management service can also be replaced by a communication configuration service, a communication optimization service, and the like.

[0161] 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 an AI-enabled CSI feedback service or an AI-model-based CSI feedback service.

[0162] 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.

[0163] Optionally, the service data of the communication management service includes an AI model corresponding to at least one of the above services to implement management of communication parameters corresponding to the at least one of the above services. For example, the AI ​​model included in the service data of the communication management service may include an AI model of an AI-based CSI feedback service to implement intelligent management of CSI through the AI ​​model; for example, the AI ​​model included in the service data of the communication management service may include an AI model of an AI-based beam management service to implement intelligent management of communication beams through the AI ​​model.

[0164] 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 the positioning information, which is also called the communication management service as an AI-enabled location positioning service or an AI model-based location positioning service.

[0165] 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).

[0166] Optionally, the data of the communication management service and the data of the wireless access communication service may be transmitted via a radio bearer (RB) between the terminal device and the wireless access device. Figure 2d As shown, 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).

[0167] 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.

[0168] 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 the parameter scale information of the AI ​​model, the structural information of the AI ​​model, and the intermediate results of the AI ​​model training (such as training hyperparameters).

[0169] 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.

[0170] Information A. Priority of data transmission for communication management services.

[0171] Specifically, the first communication unit may indicate the priority of data transmission of the communication management service through information A, and the second communication unit may schedule each service data based on the priority indicated by information B after receiving information A. 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, and the second communication unit may determine the scheduling order of the communication management service based on the information A.

[0172] Exemplarily, take the case where the data transmission of the communication management service includes multiple AI model data. When the AI ​​model corresponding to one AI model data (recorded as AI model 1) has a shorter update cycle (such as updating once every 5 minutes / 10 minutes), and the AI ​​model corresponding to another AI model data (recorded as AI model 1) has a longer update cycle (such as updating 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 idle business hours (such as in the early morning).

[0173] Information B. The data size of data transmission for communication management business.

[0174] Specifically, the first communication unit can indicate the data scale of the data transmission of the communication management service through information B. After receiving the information B, the second communication unit can determine the resources required for the data transmission of the communication management service based on the 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.

[0175] Information C. Packet loss rate requirements for data transmission of communication management services.

[0176] Specifically, the first communication unit may indicate the packet loss rate requirement of the data transmission of the communication management service through information C, and the second communication unit may subsequently determine the allowed packet loss rate of the data transmission of the communication management service based on the information C after receiving the information C.

[0177] Exemplarily, take the data transmission of the communication management service including AI model data and AI training data as an example. Generally, the data scale of AI model data is large, and the data scale of 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 restore and assemble the AI ​​model based on the received data packet, and it is not easy to restore 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.

[0178] Information D. Delay requirements for data transmission of communication management services.

[0179] 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 the information D, the second communication unit may determine the delay requirement of data transmission of the communication management service based on the information D.

[0180] Exemplarily, since the terminal device or wireless access device (for example, the wireless access device is an airplane, a satellite, etc.) may be in a mobile state, in order to avoid switching caused by movement, the data transmission of the communication management service needs to be completed before the terminal device switches from the source wireless access device to the target wireless access device (or the source base station switches to the target base station). Therefore, the delay requirement indicated by the information D here can be greater than or equal to the processing delay consumed by the terminal device switching from the current position to the target wireless access device.

[0181] In a possible implementation, the transmission configuration information sent by the first communication unit in step S401 includes at least one of the first configuration information and the 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 subsequent terminal device and the wireless access device can transmit the data of the communication management service based on the first configuration information and the second configuration information, respectively, to ensure the end-to-end service quality of the data transmission of the communication management service between the terminal device and the wireless access device.

[0182] 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 (that is, the basis for determining the transmission configuration 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.

[0183] 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 in a pre-configuration manner, or part or all of the above-mentioned at least one determination basis can be determined based on information sent by other devices, which will be described below in combination with implementation example A and implementation example B.

[0184] 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 receives 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, so that the solution can be applicable to scenarios where other devices (such as terminal devices or wireless access devices) request transmission configuration information.

[0185] 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, information on the amount of data 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.

[0186] 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.

[0187] 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 may 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.

[0188] 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.

[0189] S402. The second communication unit transmits service data based on the transmission configuration information.

[0190] In a possible implementation, in step S402, the second communication unit transmits the data of the communication management service based on the transmission configuration information, including: the second communication unit configures the transmission resources between the terminal device and the wireless access device based on the transmission configuration information; the second communication unit sends or receives the 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 the transmission resources between the terminal device and the wireless access device based on the transmission configuration information in step S402, so as to send or receive the service data of the communication management service through the transmission resources.

[0191] based on Figure 4 In the technical solution shown, the communication management service is used to manage the wireless access communication service between the 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 of data transmission of the service data of the communication management service between the terminal device and the wireless access device. Thereafter, the second communication unit can subsequently transmit the service data of the communication management service based on the transmission configuration information in step S402. Thus, while the wireless access communication service is managed by the communication management service to improve the service quality of network access, 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.

[0192] exist Figure 4In the technical solution shown, 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. Correspondingly, 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.

[0193] Implementation example 1, in Figure 4 In the technical solution shown, the second communication unit may be a wireless access device.

[0194] As an application example of implementation example 1, when the second communication unit may be a wireless access device (or a module in a wireless access device), such as Figure 5 As shown, the following steps are included.

[0195] S501. The first communication unit sends transmission configuration information to the wireless access device, wherein the transmission configuration information at least includes second configuration information, and the second configuration information is used to configure the QoS of data transmission for the communication management service on the wireless access device.

[0196] 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.

[0197] Specifically, in Figure 5 In the implementation process shown, 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.

[0198] As another application example of implementation example 1, when the second communication unit may be a wireless access device (or a module in a wireless access device), as shown in FIG. Figure 6 As shown, the following steps are included.

[0199] 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, 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.

[0200] S602. The wireless access device sends the first configuration information to the terminal device.

[0201] 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.

[0202] Specifically, in Figure 6 In the implementation process shown, the first communication unit can send transmission configuration information including 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.

[0203] Implementation example 2, in Figure 4 In the technical solution shown, the second communication unit may be a terminal device.

[0204] 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), such as Figure 7 As shown, the following steps are included.

[0205] S701. A first communication unit sends transmission configuration information to the terminal device, wherein the transmission configuration information at least includes first configuration information, and the first configuration information is used to configure the QoS of data transmission for the communication management service on the terminal device.

[0206] 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, Figure 3d In the scenario shown in FIG. 1 , in step S701, the first communication unit may 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, Figure 3a / Figure 3b / Figure 3c / Figure 3e In the scenario shown in the figure), in step S701, the first communication unit may send transmission configuration information to the terminal device through forwarding by other devices (such as CU, DU or wireless access device).

[0207] 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.

[0208] Specifically, in Figure 7 In the implementation process shown, 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 by the terminal device.

[0209] It should be noted that Figures 5 to 7 The implementation process shown can be referred to in the previous article Figure 4 The description of the related embodiments and the corresponding implementation effects are not repeated here.

[0210] As mentioned above Figures 3a to 3e From the description, we can see that Figure 4 The technical solution shown can be applied to a variety of network architectures. In order to facilitate understanding of the above implementation process, more implementation examples will be provided below for description. Figure 8 / Fig. 9 / / Fig.10 In the example shown, the communication management service is an AI service as an example for explanation, 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.

[0211] See also Figure 8 , is another schematic diagram of an implementation example of the communication method provided by the present application, wherein, Figure 8 The example shown is the previous Figure 3a An example of an application of the network architecture shown in Figure 8 In the description, the first communication unit is a RAN AI entity and the second communication unit is a terminal device, a CU or a DU.

[0212] It should be noted that the following Figure 8 In the implementation process shown, when the second communication unit is a CU, step 4 is an implementation example of the above step S301, that is, 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 an implementation example of the above step S301, that is, 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 an implementation example of the above step S301, that is, the RAN AI entity can send transmission configuration information to the terminal device through steps 4, 6 and 8. And, Figure 8 The other steps are optional.

[0213] To implement scenario 1, Figure 8In the process of creating the CRB, when the RAN AI entity, CU, 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. In this case, during the CRB creation process, the RAN AI entity can configure the AI ​​service QoS parameters for the CRB, thereby executing Figure 8 The business process shown includes the following steps.

[0214] Step 0: The terminal device sends capability information.

[0215] Exemplarily, the terminal device may 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, mobile feature information of the terminal device (i.e., mobile 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 scenarios supported by the terminal device.

[0216] For example, the Index of supported AI application scenarios can be used to identify the wireless AI service features that can be supported by the terminal device side, such as the intelligent CSI feature, etc. The CU selects the AI ​​model that can be used for the corresponding scenario based on the parameter and the capabilities of the terminal device (such as convolutional neural networks (CNN), recurrent neural networks (RNN), deep neural networks (DNN) with different layers, etc.).

[0217] For example, the mobile characteristic information of the terminal device can be used to describe the mobile speed of the terminal device, and the values ​​are high mobility (such as >40km / h), medium mobility (such as 10-40km / h), and low mobility (such as <10km / h). The subsequent RAN AI entity can determine the latency requirement for the completion of the AI ​​model / data transmission based on this parameter (i.e., the information D in the previous text).

[0218] Step 1: CU selects an AI model based on the capability information of the terminal device.

[0219] 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.

[0220] For example, when CU selects an AI model, it can consider the type and complexity of the AI ​​model (complexity affects the accuracy of the AI ​​model, and the training and reasoning of more complex AI models require more computing power and storage space), and on the other hand, it can consider the type of AI model that is suitable for the specific problems in the AI ​​business scenario. This part of information is usually statically configured by the equipment manufacturer or dynamically sent to the RAN network element in advance by the operator.

[0221] Step 2: CU sends a request message to the RAN AI entity through the G1 interface.

[0222] Specifically, in step 2, the CU initiates the AI ​​service QoS configuration process to the RAN AI entity, that is, the CU sends a request message for requesting AI QoS parameters to trigger the QoS parameter configuration process that satisfies the transmission of the AI ​​service model. The request message may include the attribute description information of the AI ​​model selected by the CU and the mobile feature information of the terminal device (that is, the parameters carried in step 0).

[0223] Exemplarily, 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 structure complexity, the amount of data required for AI model training, etc. It is used to determine the parameter values ​​of AI QoS.

[0224] Step 3: The RAN AI entity determines the transmission configuration information.

[0225] Specifically, the RAN AI entity can determine the specific AI QoS parameters (i.e., transmission configuration information) for the corresponding AI service configuration based on the AI ​​model attributes and terminal device mobility feature information of step 2 and the locally configured AI service QoS configuration strategy (similar to the correspondence between multiple AI model attributes, terminal device mobility features and multiple AI QoS parameters).

[0226] In addition, the transmission configuration information may include at least one of the AI ​​service priority, AI service data packet loss rate, AI service data scale, and AI service delay. In addition, the RAN AI entity may package the corresponding AIQoS for the RAN network element and the terminal device, namely, the first configuration information (recorded as AIQoS for UE, used for the terminal device, and used to guide the terminal device to perform parameter configuration and resource allocation QoS parameters), and the second configuration information (recorded as AIQoS for RAN, used for the RAN network element, and used to guide the RAN network element to perform parameter configuration and resource allocation QoS parameters).

[0227] Optionally, the AIQoS parameters included in AIQoS for RAN and AIQoS for UE are different. For example, AIQoS forRAN may include at least one of AI service priority, AI service data packet loss rate, AI service data scale, and AI service delay, 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, AIQoS for UE: CRB configuration parameters used for terminal equipment to report 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 delay).

[0228] Step 4: After the RAN AI entity completes the AIQoS parameter configuration, it sends the transmission configuration information to the CU through the G1 interface.

[0229] Optionally, the transmission configuration information can be carried in a response message corresponding to the request information in step 2, and carry AI QoS for RAN and AI QoS for UE.

[0230] It should be understood that step 2 and step 4 may be new messages on the G1 interface, and the message name is only a naming method. They may also be other message types or other message names on the G1 interface, which are not limited here.

[0231] Step 5: The CU establishes a CRB based on the transmission configuration information.

[0232] Specifically, after receiving the configuration parameters of the RAN AI entity, the CU determines whether there is an established CRB that can meet the parameter requirements of the AIQoS for RAN according to the AIQoS for RAN (that is, the AIQoS parameters of the established CRB are the same as the parameters in the AIQoS for RAN). If so, the existing CRB is reused, otherwise a new CRB is created and QoS is configured according to the AIQoS for RAN. The CU can configure parameters for the PDCP CRB according to the AIQoS for RAN parameters.

[0233] Step 6: CU sends transmission configuration information to DU, that is, CU sends AIQoS for RAN and AIQoS for UE to DU.

[0234] 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.

[0235] Step 7: DU performs configuration based on the transmission configuration information.

[0236] Exemplarily, the DU configures QoS parameters of the RLC / MAC / PHY layer according to the AIQoS for RAN, and the CU configures parameters for the PDCP CRB according to the AIQoS for RAN parameters.

[0237] Step 8. The DU sends the first configuration information, namely, AIQoS for UE, to the terminal device.

[0238] 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.

[0239] Step 9: The terminal device performs configuration based on the first configuration information (i.e., AIQoS for UE).

[0240] 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 AIQoS for UE.

[0241] Step 10: The terminal device sends indication information to the DU, where the indication information is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful.

[0242] Exemplarily, after completing the relevant parameter configuration, the terminal device replies with a radio resource control reconfiguration complete (RRCReconfiguration complete) message to the DU, where the message carries an indication of successful configuration.

[0243] Step 11. The DU sends indication information to the CU, where the indication information is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful and / or the indication information is used to indicate that the AI ​​QoS for RAN configuration on the DU is successful.

[0244] Exemplarily, after receiving a response from the terminal device in step 10 and 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.

[0245] After that, AI data can be transmitted between the wireless access device and the terminal device based on the corresponding configurations of AIQoS for RAN and AIQoS for UE.

[0246] Therefore, based on the implementation process of the above-mentioned 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 device to reasonably allocate wireless resources, thereby ensuring the transmission of AI services while also improving the utilization of wireless network resources.

[0247] To implement scenario 2, Figure 8 In the process of updating the AI ​​QoS parameters of the CRB, when the RAN AI entity 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 decreases, 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 RAN AI entity can perform an update (or reconfiguration) of the AI ​​service QoS parameter configuration of the CRB, thereby executing Figure 8 The business process shown includes the following steps.

[0248] Step 0: The terminal device sends updated capability information (or changed capability information).

[0249] 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.

[0250] Optionally, the terminal device can send the changed information to the CU through an enhanced radio access network basic notification area update (RAN-based notification arer update, RNA update) process, including the terminal device sending changed capability information or the identification Index of the changed AI application scenario.

[0251] Step 1: The CU selects an AI model based on the updated capability information of the terminal device.

[0252] Exemplarily, 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.

[0253] Step 2: CU sends a request message to the RAN AI entity through the G1 interface.

[0254] Exemplarily, the CU initiates an AI service QoS modification process to the RAN AI entity through the G1 interface, that is, 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 RAN AI entity. For the explanation of the relevant parameters, refer to the relevant description of the above embodiment.

[0255] Step 3: The RAN AI entity determines the transmission configuration information.

[0256] Exemplarily, the RAN AI entity determines the specific AIQoS parameters for the corresponding AI service configuration based on the AI ​​model attributes of step 2, the mobility characteristics of the terminal device, and the locally configured AI service QoS configuration policy, including at least one of the AI ​​service priority, AI service data packet loss rate, AI service data scale, and AI service delay. The corresponding AIQoS is packaged for the RAN network element and the terminal device respectively, and the relevant parameter explanations refer to the relevant descriptions of the above embodiment.

[0257] Step 4: After the RAN AI entity completes the AIQoS parameter configuration, it sends the transmission configuration information to the RAN network element through the G1 interface.

[0258] Optionally, the transmission configuration information may be carried in a response message corresponding to the request information in step 2, and may carry modified AIQoS for RAN and AIQoS for UE, wherein AIQoS for RAN and AIQoS for UE may refer to the description of the above embodiment.

[0259] Step 5: CU performs update based on the transmission configuration information.

[0260] Exemplarily, after receiving the modified parameters from the RAN AI entity, the CU updates the QoS according to the modified AIQoS forRAN, and the CU updates the parameters for the PDCP CRB according to the modified AIQoS for RAN parameters.

[0261] Step 6: CU sends transmission configuration information to DU, that is, CU sends AIQoS for RAN and AIQoS for UE to DU.

[0262] Exemplarily, the CU sends the modified AIQoS forRAN and AIQoS for UE to the DU network element via a DL RRC message transfer message of the F1 interface.

[0263] Step 7: DU performs configuration based on the transmission configuration information.

[0264] Exemplarily, the DU updates the QoS parameters of the RLC / MAC / PHY layer according to the modified AIQoS for RAN, and the CU updates the parameters for the PDCP CRB according to the modified AIQoS for RAN parameters.

[0265] Step 8. The DU sends the first configuration information (i.e., AIQoS for UE) to the terminal device.

[0266] Exemplarily, the DU sends the modified AI QoS for UE to the terminal device via an RRC Reconfiguration message of the wireless air interface Uu interface.

[0267] Step 9: The terminal device performs configuration based on the first configuration information (ie, AIQoS for UE).

[0268] 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 AIQoS for UE.

[0269] Step 10: The terminal device sends indication information to the DU, where the indication information is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful.

[0270] 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.

[0271] Step 11. The DU sends indication information to the CU, where the indication information is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful and / or the indication information is used to indicate that the AI ​​QoS for RAN configuration on the DU is successful.

[0272] Exemplarily, after the DU receives a response from the terminal device and completes the update of relevant parameters itself, it replies to the CU via the F1 interface with a UL RRC message transfer message, in which the message carries an indication of successful configuration.

[0273] After that, AI data can be transmitted between the wireless access device and the terminal device based on the corresponding configurations of AIQoS for RAN and AIQoS for UE.

[0274] By implementing scenario 2, the RAN AI entity can timely update and refresh the needs of AI services according to the updated capabilities and requirements of the terminal equipment, and then timely adjust the QoS parameters of AI service transmission to ensure the rational use of RAN resources.

[0275] See also Fig. 9 , is another schematic diagram of an implementation example of the communication method provided by the present application, wherein, Fig. 9 The example shown is the previous Figure 3b An example of an application of the network architecture shown in Fig. 9 In the description, the first communication unit is Near-RTRIC, and the second communication unit is a terminal device, CU or DU.

[0276] It should be noted that the following Fig. 9 In the implementation process shown, when the second communication unit is a CU, step 4 is an implementation example of the above step S301, that is, the Near-RT RIC can send the 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 the above step S301, that is, the Near-RTRIC can send the 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 the above step S301, that is, the Near-RT RIC can send the transmission configuration information to the terminal device through steps 4, 6 and 8. And, Fig. 9 The other steps are optional.

[0277] To implement scenario three, Fig. 9 In the process of creating the CRB, when the Near-RT RIC, CU, DU or terminal device has AI service data to be transmitted, the RAN side is triggered to establish the CRB for AI model / data transmission. In this case, during the CRB creation process, the Near-RT RIC can configure the AI ​​service QoS parameters for the CRB, thereby executing Figure 8 The business process shown includes the following steps.

[0278] It should be noted that the execution process of implementing scenario 3 is similar to that of implementing scenario 1. The difference between the two lies in the different network architectures used. In implementing scenario 3, the execution of AI service QoS parameter management is performed by Near-RTRIC, that is, the RAN AI entity in the solution steps of implementing scenario 1 is replaced by Near-RT RIC, and accordingly, the G1 interface between the RAN AI entity and the CU is replaced by the E2 interface between the Near-RT RIC and the CU.

[0279] Step 0: The terminal device sends capability information.

[0280] Step 1: CU selects an AI model based on the capability information of the terminal device.

[0281] The implementation process of step 0 and step 1 may refer to the implementation process of step 0 and step 1 in the implementation scenario 1 above.

[0282] Step 2: CU sends a request message to Near-RT RIC through the E2 interface.

[0283] Specifically, in step 2, the CU initiates the AI ​​service QoS configuration process to the Near-RT RIC through the E2 interface, that is, the CU sends a request message for requesting AI QoS parameters to trigger the QoS parameter configuration process that satisfies the transmission of the AI ​​service model. , wherein the request message may include the attribute description information of the AI ​​model selected by the CU and the terminal device mobility feature information (parameters carried in step 0).

[0284] Step 3: Near-RT RIC determines the transmission configuration information.

[0285] Specifically, the Near-RT RIC determines the specific AIQoS parameters for the corresponding AI service configuration based on the AI ​​model attributes in step 2, the mobility characteristics of the terminal device, and the locally configured AI service QoS configuration policy, including AI service priority, AI service data packet loss rate, AI service data scale, and AI service latency. It also packages the corresponding AIQoS for the RAN network element and the terminal device respectively.

[0286] Step 4: After the Near-RT RIC completes the AIQoS parameter configuration, it sends the transmission configuration information to the CU through the G1 interface.

[0287] Optionally, the transmission configuration information is a response message corresponding to the request information in step 2, and carries AIQoS forRAN and AIQoS for UE.

[0288] It should be understood that step 2 and step 4 may be new messages on the E2 interface, and the message name is only a naming method. It may also be other message types or other message names on the E2 interface, which are not limited here.

[0289] Step 5: The CU establishes a CRB based on the transmission configuration information.

[0290] Step 6: CU sends transmission configuration information to DU, that is, CU sends AIQoS for RAN and AIQoS for UE to DU.

[0291] Step 7: DU performs configuration based on the transmission configuration information.

[0292] Step 8. The DU sends the first configuration information (i.e., AIQoS for UE) to the terminal device.

[0293] Step 9: The terminal device performs configuration based on the first configuration information (i.e., AIQoS for UE).

[0294] Step 10: The terminal device sends indication information to the DU, where the indication information is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful.

[0295] Step 11. The DU sends indication information to the CU, where the indication information is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful and / or the indication information is used to indicate that the AI ​​QoS for RAN configuration on the DU is successful.

[0296] The implementation process of steps 5 to 11 may refer to the implementation process of steps 5 to 11 in the implementation scenario 1 above.

[0297] After that, AI data can be transmitted between the wireless access device and the terminal device based on the corresponding configurations of AIQoS for RAN and AIQoS for UE.

[0298] Therefore, based on the implementation process of the above-mentioned implementation scenario three, Near-RT RIC can determine the QoS parameter configuration for AI service transmission based on the actual needs of the AI ​​service, and guide the wireless access equipment and terminal equipment to reasonably allocate wireless resources, ensuring the transmission of AI services while also improving the utilization of wireless network resources.

[0299] To implement scenario 4, Fig. 9 In the process, 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 decreases, 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 Fig. 9 The business process shown includes the following steps.

[0300] It should be noted that the execution process of implementing scenario 4 is similar to that of implementing scenario 2. The difference between the two lies in the different network architectures used. In implementing scenario 4, the execution of AI service QoS parameter management is performed by Near-RTRIC, that is, the RAN AI entity in the solution steps of implementing scenario 2 is replaced by Near-RT RIC, and accordingly, the G1 interface between the RAN AI entity and the CU is replaced by the E2 interface between the Near-RT RIC and the CU.

[0301] Step 0: The terminal device sends updated capability information (or changed capability information).

[0302] Step 1: The CU selects an AI model based on the updated capability information of the terminal device.

[0303] The implementation process of step 0 and step 1 may refer to the implementation process of step 0 and step 1 in the previous implementation scenario 2.

[0304] Step 2: CU sends a request message to the Near-RT RIC through the G1 interface.

[0305] 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.

[0306] Step 3: Near-RT RIC determines the transmission configuration information.

[0307] Exemplarily, the Near-RT RIC determines the specific AIQoS parameters for the corresponding AI service configuration based on the AI ​​model attributes in step 2, the mobility characteristics of the terminal device, and the locally configured AI service QoS configuration policy, including AI service priority, AI service data packet loss rate, AI service data scale, and AI service latency. The corresponding AIQoS is packaged for the RAN network element and the terminal device respectively.

[0308] Step 4: After the Near-RT RIC completes the AIQoS parameter configuration, it sends the transmission configuration information to the RAN network element through the E2 interface.

[0309] Exemplarily, after the Near-RT RIC function completes the AIQoS parameter modification, it returns the specific modified parameters to the CU through the E2 interface, that is, it replies to the request message / AIQoS parameter response message of step 2 and carries the modified AIQoS forRAN and AIQoS for UE.

[0310] Step 5: The CU establishes a CRB based on the transmission configuration information.

[0311] Step 6: CU sends transmission configuration information to DU, that is, CU sends AIQoS for RAN and AIQoS for UE to DU.

[0312] Step 7: DU performs configuration based on the transmission configuration information.

[0313] Step 8. The DU sends the first configuration information (i.e., AIQoS for UE) to the terminal device.

[0314] Step 9: The terminal device performs configuration based on the first configuration information (ie, AIQoS for UE).

[0315] Step 10: The terminal device sends indication information to the DU, where the indication information is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful.

[0316] Step 11. The DU sends indication information to the CU, where the indication information is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful and / or the indication information is used to indicate that the AI ​​QoS for RAN configuration on the DU is successful.

[0317] 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.

[0318] After that, AI data can be transmitted between the wireless access device and the terminal device based on the corresponding configurations of AIQoS for RAN and AIQoS for UE.

[0319] Therefore, based on the implementation process of the above-mentioned 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 timely adjust the QoS parameters of AI service transmission to ensure the rational use of RAN resources.

[0320] See also Fig.10 , is another schematic diagram of an implementation example of the communication method provided by the present application, wherein, Fig.10 The example shown is the previous Figure 3c An example of an application of the network architecture shown in Fig. 9 In the example, the first communication unit is an internal module of the CU and the second communication unit is a terminal device or DU.

[0321] It should be noted that the following Fig.10 In the implementation process shown, when the second communication unit is a DU, step 4 is an implementation example of the above step S301, that is, the first communication unit can send the transmission configuration information to the DU through step 4; when the second communication unit is a terminal device, steps 4 and 6 are an implementation example of the above step S301, that is, the first communication unit can send the transmission configuration information to the terminal device through steps 4 and 6. And, Fig.10 The other steps are optional.

[0322] To implement scenario 5, Fig.10In the process of creating the CRB, when the first communication unit or CU or DU or terminal device has AI service data to be transmitted, the RAN side is triggered to establish a CRB for AI model / data transmission. Then, during the process of creating the CRB, the first communication unit can configure the AI ​​service QoS parameters of the CRB, thereby executing Fig.10 The business process shown includes the following steps.

[0323] Step 0: The terminal device sends capability information.

[0324] Step 1: CU selects an AI model based on the capability information of the terminal device.

[0325] The implementation process of step 0 and step 1 may refer to the implementation process of step 0 and step 1 in the implementation scenario 1 above.

[0326] Step 2: The first communication unit located inside the CU determines transmission configuration information.

[0327] Specifically, the first communication unit determines the specific parameters of AI QoS configuration for the corresponding AI service based on the AI ​​model attributes of step 1, the mobility characteristics of the terminal device, and the locally configured AI service QoS configuration policy, including AI service priority, AI service data packet loss rate, AI service data scale, and AI service delay. The corresponding AI QoS is packaged for the DU and the terminal device respectively.

[0328] Step 3: The CU establishes a CRB based on the transmission configuration information.

[0329] Specifically, based on the transmission configuration information determined by the first communication unit, the CU determines according to AIQoS for RAN whether there is an established CRB that can meet the parameter requirements of AIQoS for RAN (that is, the AIQoS parameters of the established CRB are the same as the parameters in AIQoS for RAN). If so, the existing CRB is reused; otherwise, a new CRB is created and QoS configuration is performed according to AIQoS forRAN. The CU can configure parameters for the PDCP CRB according to the AIQoS for RAN parameters.

[0330] Step 4: CU sends transmission configuration information to DU, that is, CU sends AIQoS for RAN and AIQoS for UE to DU.

[0331] Step 5: DU performs configuration based on the transmission configuration information.

[0332] Step 6: DU sends the first configuration information (i.e., AIQoS for UE) to the terminal device.

[0333] Step 7: The terminal device performs configuration based on the first configuration information (i.e., AIQoS for UE).

[0334] Step 8. The terminal device sends indication information to the DU, where the indication information is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful.

[0335] Step 9. The DU sends indication information to the CU, where the indication information is used to indicate that the AIQoS for UE configuration on the terminal device is successful and / or the indication information is used to indicate that the AIQoS for RAN configuration on the DU is successful.

[0336] After that, AI data can be transmitted between the wireless access device and the terminal device based on the corresponding configurations of AIQoS for RAN and AIQoS for UE.

[0337] 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.

[0338] 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 for 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, thereby ensuring AI service transmission while also improving the utilization rate of wireless network resources.

[0339] To implement scenario six, Fig.10 In the process, when the first communication unit version 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 decreases, the terminal device may request a higher-precision AI model, and then request the network to update the AI ​​model. Then, 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 Fig.10 The business process shown includes the following steps.

[0340] It should be noted that the execution process of implementing scenario 6 is similar to that of implementing scenario 2. The difference between the two lies in the different network architectures used. In implementing scenario 6, the execution of AI service QoS parameter management is performed by the first communication unit located inside the CU, that is, the RAN AI entity in the solution steps of implementing scenario 2 is replaced by the first communication unit located inside the CU.

[0341] Step 0: The terminal device sends updated capability information (or changed capability information).

[0342] Step 1: The CU selects an AI model based on the updated capability information of the terminal device.

[0343] The implementation process of step 0 and step 1 may refer to the implementation process of step 0 and step 1 in the previous implementation scenario 2.

[0344] Step 2: The first communication unit located inside the CU determines transmission configuration information.

[0345] Specifically, the first communication unit determines the specific parameters of AI QoS configuration for the corresponding AI service based on the AI ​​model attributes of step 1, the mobility characteristics of the terminal device, and the locally configured AI service QoS configuration policy, including AI service priority, AI service data packet loss rate, AI service data scale, and AI service delay. The corresponding AI QoS is packaged for the DU and the terminal device respectively.

[0346] Step 3: The CU establishes a CRB based on the transmission configuration information.

[0347] Specifically, based on the transmission configuration information determined by the first communication unit, the CU determines according to AIQoS for RAN whether there is an established CRB that can meet the parameter requirements of AIQoS for RAN (that is, the AIQoS parameters of the established CRB are the same as the parameters in AIQoS for RAN). If so, the existing CRB is reused; otherwise, a new CRB is created and QoS configuration is performed according to AIQoS forRAN. The CU can configure parameters for the PDCP CRB according to the AIQoS for RAN parameters.

[0348] Step 4: CU sends transmission configuration information to DU, that is, CU sends AIQoS for RAN and AIQoS for UE to DU.

[0349] Step 5: DU performs configuration based on the transmission configuration information.

[0350] Step 6: The DU sends the first configuration information (i.e., AIQoS for UE) to the terminal device.

[0351] Step 7: The terminal device performs configuration based on the first configuration information (i.e., AIQoS for UE).

[0352] Step 8. The terminal device sends indication information to the DU, where the indication information is used to indicate that the AI ​​QoS for UE configuration on the terminal device is successful.

[0353] Step 9. The DU sends indication information to the CU, where the indication information is used to indicate that the AIQoS for UE configuration on the terminal device is successful and / or the indication information is used to indicate that the AIQoS for RAN configuration on the DU is successful.

[0354] After that, AI data can be transmitted between the wireless access device and the terminal device based on the corresponding configurations of AIQoS for RAN and AIQoS for UE.

[0355] 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.

[0356] 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.
