Session establishment method and device, system

[0001] The present application claims priority to the Chinese patent application No. 202411320097.4, filed on September 21, 2024, with the State Intellectual Property Office of China, and the Chinese patent application No. 202411320097.4 has the invention name of “Session establishment method and device, system”, the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, in particular to a session establishment method and device, system. BACKGROUND

[0003] In the past decade, artificial intelligence technology and machine learning algorithms (artificial intelligence (AI) / machine learning (ML)) have made a leap, and deep learning models represented by neural networks (NN) and Transformers have shown strong feature extraction and fitting capabilities in many fields, and have derived various intelligent applications in various industries.

[0004] In the field of wireless communication, on the one hand, AI models can replace modules in communication systems such as beam management and channel prediction, and through their strong model capacity and data fitting capabilities, they can automatically replace traditional modules and bring performance gains. On the other hand, the computing, transmission capabilities and perceived information in the network can also support third-party AI applications of mobile terminals, such as offloading the computing of third-party AI applications to computing nodes in the network, or providing better personalized services based on the environmental information and user behavior perceived by the network. Therefore, the deep integration of AI and communication has also become one of the important visions of 6G systems.

[0005] However, the current wireless network only considers the communication services of users, and mainly faces the transmission function during the user registration and service establishment processes. When AI computing and other services are also considered as endogenous functions of the wireless network, both transmission and computing functions need to be considered, in addition to the existing data channel establishment, the influence of computing and the new end-to-end quality of service (QoS) requirements of AI tasks on communication computing also need to be considered.

[0073] The embodiments of the present application will be described below in conjunction with the accompanying drawings. The terms used in the implementation part of the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0074] FIG. 1 shows a possible, non-limiting, schematic diagram of a system. As shown in FIG. 1, the communication system 1000 includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system 1000 also includes an Internet 300. The RAN 100 includes at least one RAN node (e.g., 110a and 110b in FIG. 1, collectively referred to as 110) and at least one terminal (e.g., 120a-120j in FIG. 1, collectively referred to as 120). The RAN 100 can also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in FIG. 1), etc. The terminal 120 is connected to the RAN node 110 in a wireless manner. The RAN node 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the RAN node 110 in the RAN 100 can be different physical devices, or can be the same physical device integrated with the logical functions of the core network and the logical functions of the radio access network.

[0075] The RAN 100 can be a 3rd generation partnership project (3GPP) related cellular system, e.g., a 4G, 5G mobile communication system, or an evolution of 5G, e.g., a 6th generation (6G) mobile communication system. The RAN 100 can also be an open radio access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless-fidelity (Wi-Fi) system based on IEEE 802.11 standards. The RAN 100 can also be a communication system that combines two or more of the above systems.

[0076] The RAN nodes 110, which can also be referred to as access network devices, RAN entities or access nodes, etc., form part of the communication system 1000 and are responsible for enabling wireless access to the communication system 1000 for terminals 120. The RAN nodes 110 in the communication system 1000 can be the same type of nodes or different types of nodes. In some scenarios, the roles of the RAN nodes 110 and the terminals 120 are relative, e.g., a net element 120i in Figure 1 can be a helicopter or a drone, which can be configured to be a mobile base station, for a terminal 120j that accesses the RAN 100 through the net element 120i, the net element 120i is a base station; but for the base station 110a, the net element 120i is a terminal. The RAN nodes 110 and the terminals 120 are sometimes referred to as communication apparatuses, e.g., the net elements 110a and 110b in Figure 1 can be understood as communication apparatuses with base station functions, and the net elements 120a-120j can be understood as communication apparatuses with terminal functions.

[0077] In a possible scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc. The RAN node can be a macro base station (such as 110a in FIG. 1), a micro base station or an indoor station (such as 110b in FIG. 1), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the access network device in a vehicle to everything (V2X) technology can be a road side unit (RSU).

[0078] In another possible scenario, a terminal is assisted by multiple RAN nodes to implement wireless access, and different RAN nodes respectively implement part of the functions of a base station. For example, the RAN node can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a radio frequency remote unit (RRU), an active antenna processing unit (AAU), or a remote radio head (RRH).

[0079] The CU (or CU-CP and CU-UP), DU or RU can also have different names in different systems, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. For the convenience of description, the CU, CU-CP, CU-UP, DU and RU are taken as examples for description in this application. Any one of 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.

[0080] The terminal can also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. The terminal can be widely applied to various scenarios, such as device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), internet of things (IoT), virtual reality (VR) device, augmented reality (AR) device, industrial control, autonomous driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, tablet computer, computer with wireless transceiver function, wearable device, vehicle, unmanned aerial vehicle, helicopter, airplane, ship, robot, mechanical arm, smart home device, light terminal device (light UE), reduced capability user equipment (REDCAP UE), smart point of sale (POS) machine, customer-premises equipment (CPE), etc. The terminal can also be a vehicle device, such as a whole vehicle device, vehicle-mounted module, vehicle-mounted chip, on board unit (OBU) or telematics box (T-BOX), etc. Embodiments of the present application do not limit the device form of the terminal.

[0081] The communication between the access network device and the terminal device follows a certain protocol layer structure. The protocol layer can include a control plane protocol layer and a user plane protocol layer. The control plane protocol layer can include at least one of 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, etc. The user plane protocol layer can include at least one of a service data adaptation protocol (SDAP) layer, a PDCP layer, an RLC layer, a MAC layer, or a physical layer, etc.

[0082] For the network element in the ORAN system, the corresponding relationship of the protocol layer functions that can be implemented can refer to Table 1:

[0083] Table 1

[0084] The base station and the terminal can be fixed in position or movable. The base station and the terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water; can also be deployed on an airplane, a balloon, and a man-made satellite. The embodiments of the present application do not limit the application scenarios of the base station and the terminal.

[0085] The roles of the base station and the terminal can be relative, for example, the helicopter or the unmanned aerial vehicle 120i in FIG. 1 can be configured as a mobile base station, and 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 a wireless air interface protocol. Of course, 110a and 120i can also communicate through an interface protocol between base stations and base stations, at this time, relative to 110a, 120i is also a base station. Therefore, the base station and the terminal can be collectively referred to as a communication device, 110a and 110b in FIG. 1 can be referred to as a communication device with a base station function, and 120a-120j in FIG. 1 can be referred to as a communication device with a terminal function.

[0086] In the embodiments of the present application, the base station is also referred to as an access network device, and the apparatus for implementing the functions of the access network device can be the access network device, or can be an apparatus capable of supporting the access network device to implement the functions, for example, a chip system, a hardware circuit, a software module, or a hardware circuit plus a software module. The apparatus can be installed in the access network device or used in combination with the access network device. In the embodiments of the present application, only the apparatus for implementing the functions of the access network device is taken as an example for description, and the present application is not limited in this way.

[0087] It can be understood that the present application can be applied between the access network device and the terminal.

[0088] It should be understood that the number and type of each device in the communication system shown in FIG. 1 are only illustrative, and the present application is not limited thereto. In actual applications, more terminals, more access network devices, and other network elements, for example, core network devices, and / or network elements for implementing artificial intelligence functions can also be included in the communication system.

[0089] It can be understood that all or part of the functions implemented by one or more of the terminal, the access network device, the core network device, or the network element for implementing the artificial intelligence function can be virtualized, that is, implemented by one or more of a special processor or a general processor and a corresponding software module. Among them, the terminal and the access network device involve the interface of air interface transmission, and the transceiving function of the interface can be implemented by hardware. The core network device, such as an operation administration and maintenance (OAM) network element, can be virtualized. Optionally, one or more functions of the virtualized terminal, access network device, core network device, or network element for implementing the artificial intelligence function can be implemented by a cloud device, such as a cloud device in an over the top (OTT) system.

[0090] In the present application, “sending information to (for example, a terminal)” or related illustrations in the drawings can be understood as that the destination of the information is the terminal. It can include directly or indirectly sending information to the terminal. “Receiving information from (for example, a terminal)” or “receiving information from (for example, a terminal)”, or related illustrations in the drawings can be understood as that the source of the information is the terminal, and can include directly or indirectly receiving information from the terminal. The information can be processed as necessary between the source and the destination, for example, format change, etc., but the destination can understand the valid information from the source. Similar expressions in the present application can be understood in a similar way, which will not be repeated here.

[0091] The communication system to which the present application is applicable will be described below with the fifth generation mobile communication network service-based interface-based non-roaming architecture shown in FIG. 2a as an example. The communication system mainly includes an access and mobility management function (AMF), a session management function (SMF), a user plane function (UPF), a network exposure function (NEF), and an application function (AF).

For example, the session management function entity can also be replaced by "session management function" or other names. Moreover, the session management function entity can also correspond to an entity including other functions in addition to the session management function. The user plane function entity can also be replaced by "user plane function" or other names, and the user plane function entity can also correspond to an entity including other functions in addition to the user plane function.

The AI module introduced above is responsible for providing the execution of an AI task, and the logical function network element AIMF is responsible for the registration and physical bearing construction of an AI service. The arc arrow and the dashed arrow in FIG. 2b represent signaling interaction of service registration or establishment. The UE, the cloud server, and the AI node in FIG. 2b all have computing resources.

[0104] Among them, the present scheme is compatible with the O-RAN architecture, the AI module can be located in the DU, the CU, or the cloud platform, and the AIMF function can also be located in the CU, the core network, or as part of the RAN intelligent controller (RIC) function.

[0105] The architecture of the embodiments of the present application is described above, and the method of the embodiments of the present application is described in detail below.

[0106] Referring to FIG. 3, a flowchart of a session establishment method is provided. Optionally, the method can be applied to the communication system described above, such as the communication system shown in FIG. 1. The session establishment method shown in FIG. 3 can include steps 301-305. Steps 301-305 are as follows:

[0107] 301. The terminal device sends first information, the first information including a session ID, and the first information being used to request an AI service. Correspondingly, the first network element receives the first information.

[0108] The first network element can be, for example, an AIMF.

[0109] 302、the first network element sends second information, the second information indicating task configuration and data channel establishment. Correspondingly, the second network element receives the second information.

[0110] The second network element may be, for example, an SU. Alternatively, the first network element may also send the second information to a third network element (such as a CU or a DU), and inform the SU through the CU or the DU (hereinafter, the CU is taken as an example, and it can be understood that the operations performed by the CU are also applicable to the DU).

[0111] In a possible implementation, the second information includes first configuration information, the first configuration information including one or more of the following: data channel information between the second network element and the third network element (such as an SU-CU), and AI QoS (Quality of Service) requirement of an artificial intelligence service between the terminal device and the second network element (UE-SU). Alternatively, the AI QoS requirement between the UE-SU includes one or more of the following: total end-to-end AI QoS requirement, and AI QoS requirement of each segment between the UE-SU.

[0112] In another possible implementation, the second information includes channel establishment indication information, the channel establishment indication information being used to determine a transmission protocol of AI interaction data. Alternatively, the channel establishment indication information includes one or more of the following: session ID, supported transmission data type, and transmission protocol or compression setting.

[0113] In yet another possible implementation, the second information includes second configuration information, the second configuration information indicating one or more of the following: application (APP) identifier, and terminal device side model configuration.

[0114] The second information may also include two or three of the first configuration information, the channel establishment indication information, and the second configuration information, and the present solution does not limit this.

[0115] For example, the AIMF indicates, to the SU, the following: task configuration (application identifier, model identifier and configuration, sub-model allocation / dynamically adjustable range, auxiliary network / sensing information, AI QoS, etc.), channel establishment indication (session ID, supported transmission data type, and transmission protocol or compression setting thereof, the channel establishment indication being used to determine a transmission protocol of AI interaction data), and AI container (indicating application identifier and UE side model configuration, and being used to inform UE side configuration). The AIMF indicates, to the SU, local model construction and AI QoS configuration.

[0116] 303、the second network element sends fourth information, the fourth information being used to request AI task data channel establishment. Correspondingly, the third network element receives the fourth information.

[0117] In a possible implementation, the fourth information includes one or more of channel establishment indication information, AI QoS of air interface transmission, and second configuration information. The channel establishment indication information is used to determine a transmission protocol of the AI interaction data, and the second configuration information indicates one or more of an application identifier and a terminal device side model configuration.

[0118] In a possible implementation, the channel establishment indication information includes one or more of a session ID, a supported transmission data type, and a transmission protocol or compression setting.

[0119] For example, the SU initiates a channel establishment request to the CU, and the request carries one or more of channel establishment indication (UE identifier), channel establishment indication (SU-CU data channel information, supported transmission data type, and transmission protocol or compression setting thereof), AI QoS of air interface side transmission (AIMF decomposition good indication or SU split indication), AI container (application identifier and UE side model configuration), and network assistance information.

[0120] The CU completes establishment and transmission setting of the SU-CU data channel, initiates signaling interaction (transfers the session ID, AI container, and AI QoS of the decomposed UE) to the UE, and establishes an air interface task bearer. Optionally, the CU establishes different data radio bearers (DRBs) according to different types of data or establishes a newly designed air interface task bearer (traffic radio bearer, TRB) in a task granularity.

[0121] 304. The third network element establishes a data channel with the second network element.

[0122] In a possible implementation, the CU completes establishment and transmission setting of the SU-CU data channel, initiates signaling interaction (transfers the session ID, AI container, and AI QoS of the decomposed UE) to the UE, and establishes an air interface task bearer.

[0123] In a possible implementation, the third network element generates AN data channel information and matches the AN data channel information with data channel information between the second network element and the third network element.

[0124] In a possible implementation, the third network element sends, to the UE, sixth information carrying an APP / task / model, and the sixth information is used to indicate a terminal device side model or task configuration.

[0125] Exemplarily, according to the AIQoS of the air interface data channel, the base station and the UE complete RRC reconfiguration, which carries APP / task / model indication, for indicating the UE side to perform model / task configuration, to establish a DRB (for each data flow) or a TRB (for each task, distinguishing data types and AIQoS according to protocol layer header). After receiving the feedback, the CU generates access network AN data channel information, matches the information with the SU-CU data channel information for mapping and forwarding, and realizes mapping and shunting of different bearers to tasks by the gNB (such as the CU or the DU).

[0126] In a possible implementation, the third network element also establishes a data channel between the APP server (which can be referred to as a CU-APP). For this introduction, please refer to the description of the embodiments below, which will not be described in detail here.

[0127] In a possible implementation, the third network element also generates access network AN data channel information, and matches the AN data channel information with the data channel information between the second network element and the third network element. For this introduction, please refer to the description of the embodiments below, which will not be described in detail here.

[0128] In a possible implementation, the third network element also sends sixth information to the UE, the sixth information carrying an application / task / model, and the sixth information being used to indicate terminal device side model or task configuration.

[0129] In another possible implementation, the second network element also establishes a data channel between the APP server (which can be referred to as a SU-APP). For this introduction, please refer to the description of the embodiments below, which will not be described in detail here.

[0130] In a possible implementation, the second network element also matches the data channel information between the second network element and the third network element with the data channel information between the second network element and the fourth network element. The third network element is an access network element, and the fourth network element is a core network element. For example, the third network element is a CU, and the fourth network element is a UPF. For this introduction, please refer to the description of the embodiments below, which will not be described in detail here.

[0131] 305、The third network element sends third information, the third information indicating that the session establishment is completed. Correspondingly, the first network element receives the third information.

[0132] Optionally, the third network element can also send the above information to the second network element, which forwards the information to the first network element.

[0133] The embodiment of the application provides a channel establishment process of AI service provided by a wireless network. Based on the network AI task data channel construction of the AIMF, the network AI service is guided to be established by the AIMF function network element, and the physical bearing and mapping relationship of the AI task is guided to be established by the control signaling, so that the registration service of the network AI application is realized; the newly established data channel / control mode can independently provide the AI service, does not affect the communication process, supports independent evolution and extension and update. Moreover, the original CU-APP data channel is used, and the existing protocol and interface are slightly changed.

[0134] The session establishment method provided by the application will be specifically introduced below in combination with the embodiments.

[0135] Embodiment 1

[0136] As shown in FIG. 4, it is a schematic diagram of a session establishment method provided by the application. In combination with FIG. 5, the corresponding scenario of the example is the AI service in the closed loop of the RAN. As shown in FIG. 5, the execution of the AI service is completed by the computing node SU (optionally, also including the UE) in the RAN, and the participation of the cloud server is not required. The arc arrow shown in FIG. 5 represents the business data flow; the dotted arrow is the optional control signaling interaction, which is used to indicate the data channel establishment, and the data channel establishment is optionally guided by the AIMF to the SU or the CU. The session establishment method provided by the application will be introduced below in combination with FIG. 4. As shown in FIG. 4, the method can include steps 401-410, and specifically as follows:

[0137] 401. The AIMF issues an APP ID supporting the network to provide the AI service.

[0138] For example, the AIMF issues an APP ID list and related configurations (network closed loop) supported by the network to the UE.

[0139] Alternatively, step 401 can also be that the APP informs the UE whether the network participates in / provides the AI service through an application message.

[0140] 402. The UE initiates a network AI service request.

[0141] For example, the UE initiates an AI service request to the AIMF through the base station, and the request can carry a session ID. Optionally, the request also carries the terminal capability report.

[0142] Optionally, the UE initiates the above request to the gNB through the RRC message, and the gNB forwards the request to the AIMF for processing. Alternatively, the UE sends the request to the AIMF through the NAS layer / a new AI control protocol layer.

[0143] Alternatively, steps 401-402 can also be that the UE directly requests the AI application service to the network, and whether the network supports is fed back.

[0144] 403. AIMF performs service registration configuration and task orchestration.

[0145] Optionally, AIMF performs AI service response and initialization configuration based on application subscription and SU status and model deployment, determines task ID and mapping information, and also includes configuration information such as UE-SU end-to-end total AIQoS requirements (e.g., computing latency, energy consumption, service accuracy) and / or AIQoS requirements for each segment.

[0146] Specifically, AIMF determines the data channel information (tunnel info) of the SU-CU and formulates AIQoS (compression parameter requirements such as throughput latency, energy consumption, model capability, and quantization pruning for different types of interactive data), and / or, formulates a pre-decomposed AIQoS based on the computing capabilities of the SU and UE and the transmission capabilities of each segment. This data channel information may include a tunnel endpoint identifier, used to indicate the transmission network layer information of the SU-CU channel.

[0147] 404. AIMF issues task configuration and data channel establishment instructions to SU.

[0148] Optionally, AIMF may instruct the SU on one or more of the following: task configuration (application identifier, model identifier and configuration, sub-model allocation or dynamically adjustable range, auxiliary network or perception information, AIQoS, etc.), channel establishment instruction (session ID, supported data types and their transmission protocols or compression settings, etc.), and AI container (indicating application identifier, UE-side model configuration, etc.). The channel establishment instruction is used to determine the transmission protocol for AI interaction data. The AI ​​container is used to inform the UE-side configuration.

[0149] Optionally, AIMF can also issue instructions to the CU, which then forwards the task configuration to the SU.

[0150] 405. SU configures the local application model according to the instructions.

[0151] SU completes local model building and input / output matching or transformation based on the task configuration. Optionally, SU configures according to the decomposed AIQoS, or SU performs local decomposition based on the total AIQoS, configures it, and then informs CU.

[0152] 406. SU requests the establishment of an AI data channel.

[0153] SU-CU data channel establishment. Exemplarily, the SU initiates a channel establishment request to the CU, which carries one or more of the following: channel establishment indication (such as including UE identifier), channel establishment indication (SU-CU data channel information, supported transmission data type and its transmission protocol or compression setting, etc.), AI QoS (AIMF resolution indication or SU split indication) of air interface side transmission, AI container (indicating application identifier, UE side model configuration, etc.). Optionally, the request also carries network assistance information.

[0154] Among them, the CU completes the establishment and transmission setting of the SU-CU data channel, initiates signaling interaction (transfers session ID, AI container, and AI QoS of the UE after resolution) to the UE, for establishing air interface task bearer. Optionally, the CU establishes different data radio bearers (DRB) according to different types of data or establishes a newly designed air interface task bearer (TRB) in a task granularity.

[0155] 407. Establishing an air interface AI task bearer.

[0156] Exemplarily, according to the AI QoS of the air interface data channel, the base station and the UE complete RRC reconfiguration, which carries APP / task / model indication, for indicating the UE side to perform model / task configuration, to establish DRB (for each data flow) or TRB (for each task, distinguishing data type and AI QoS according to protocol layer header identification). The CU generates AN data channel information after receiving the feedback, matches the information with the SU-CU data channel information for mapping forwarding, and realizes mapping and shunting of different bearers to tasks by the gNB (such as CU or DU).

[0157] 408. The CU or DU sends an AI session task response.

[0158] For example, after the air interface bearer is established, the CU sends an AI task session establishment completion message to the SU.

[0159] 409. The SU feeds back complete session information to the AIMF, and the establishment of the network AI task is completed.

[0160] Optionally, the CU can also feed back the above information to the AIMF.

[0161] 410. Starting the execution and data interaction of the AI task.

[0162] The example gives the task registration and data channel establishment process of the wireless network providing AI service, and the AIQoS considering the calculation capabilities of each segment is configured by the network side to guarantee the AI service quality. Specifically, the AIMF responds to the AI service request of the UE, formulates the AIQoS of each segment or the total AIQoS, and instructs the SU or CU to establish the data channel of the AI service; the CU encapsulates the UE side model configuration through the AI container when performing RRC reconfiguration with the UE to establish the air interface bearer; and the CU serves as an intermediate network element and is responsible for matching the data port identifiers of each segment of the AI task for data flow mapping and forwarding.

[0163] Embodiment 2

[0164] As shown in FIG. 6, it is a schematic diagram of a session establishment method provided by the present application. In combination with FIG. 7, the example corresponds to a scenario in which the end network cloud jointly performs an AI task. As shown in FIG. 7, the traffic interacting with the cloud is forwarded by the CU: 1) for the UE uplink traffic, the CU needs to distinguish which traffic is directly transmitted to the APP server through the UPF and which traffic needs to be forwarded to the SU for RAN side execution. 2) for the data flow from the SU to the CU, the CU needs to distinguish which data flow is uploaded to the APP server for calculation and which data flow needs to be returned to the UE according to the business logic. 3) for the traffic from the APP to the CU through the UPF, it needs to be distinguished which traffic is directly transmitted to the UE and which traffic needs to be processed through the SU. As shown in FIG. 6, the method can include steps 601-609, which are specifically as follows:

[0165] 601. The AIMF issues an APP ID supporting network-provided AI services.

[0166] 602. The UE initiates a network AI service request.

[0167] For the introduction of steps 601-602, reference can be made to the description of steps 401-402 in the embodiment shown in FIG. 4, which will not be repeated here.

[0168] 603. The AIMF performs service registration configuration and task scheduling.

[0169] Among them, the AIMF can optionally jointly gNB-SU, or jointly one or more APPs to perform AI service registration and initialization configuration, determine the task ID and mapping information, and also include AIQoS configuration information of each data channel. For this introduction, reference can be made to the description of step 403 in the embodiment shown in FIG. 4, which will not be repeated here.

[0170] 604. The AIMF issues task configuration and data channel establishment instructions.

[0171] Optionally, the AIMF issues a task configuration and data channel establishment indication to the CU, which informs the SU through the CU; or the AIMF directly sends the configuration to the SU. Meanwhile, the AIMF optionally issues cloud model configuration information (through an application programming interface (API)) to the APP server end.

[0173] For this introduction, refer to the description of step 405 in the embodiment shown in FIG. 4, which will not be repeated here.

[0174] 605b. SU-CU data channel establishment.

[0175] After the SU completes the local model configuration, the SU initiates an AI task data channel establishment request (user plane / data plane) to the CU, indicating a double-end task / model, a double-end identifier, an AI QoS requirement of the channel, a transmission protocol, etc., and the CU is responsible for the mapping and shunting of the task data to the SU. For bidirectional transmission of the same data stream, the same or different data channels can be optionally used. Optionally, the CU can also initiate a channel establishment request to the SU.

[0176] 605c. APP server configures an APP-side AI model.

[0177] 606. CU-APP data channel establishment.

[0178] The CU-APP establishes a data channel from the gNB to the UPF to the APP. For example, according to the information indicated by the AIMF, after the CU establishes an N3 channel with the UPF (with the participation of the AMF and the SMF), the CU matches the SU-CU data channel information (for example, two channels can need to be built) with the N3 data channel information, which is used to realize the uplink and downlink AI task interaction of the SU-APP, and the gNB and the UPF are responsible for the mapping and shunting of the task data to the APP server.

[0179] 607. Establishment of an air interface AI task bearer.

[0180] According to the issued air interface AI bearer AI QoS, the base station and the UE complete RRC reconfiguration to establish a DRB (for each data stream) or a TRB (for each task, distinguishing data types and AI QoS according to protocol layer headers), and the CU or the DU realizes the mapping and shunting of different bearers to tasks.

[0181] 608. The CU or the DU sends an AI session task response.

[0182] For example, after the air interface bearer is established, the CU feeds back complete session information to the AIMF, thereby completing the establishment of the network AI task.

[0183] 609、Start the execution of AI tasks and data interaction.

[0184] This example gives the establishment process of the AI task data channel in the scenario where the end-to-end cloud jointly performs AI services and the CU is responsible for bidirectional relay forwarding. The AI configuration indication and AI QoS configuration are added when the data channel is established, and the CU is responsible for bidirectional data mapping and shunt forwarding.

[0185] Embodiment 3

[0186] As shown in FIG. 8, it is a schematic diagram of a session establishment method provided by the present application. In combination with FIG. 9, the scenario corresponding to this example is that the end-to-end cloud jointly performs AI tasks. As shown in FIG. 9, the traffic interacting with the cloud is directly sent by the SU: 1) for UE uplink traffic, the CU needs to distinguish which are directly transmitted to the APP server through the UPF and which need to be forwarded to the SU for RAN-side executed AI task data. 2) for the data executed by the SU, the SU needs to distinguish according to the business logic which is uploaded to the APP server for calculation through the UPF and which needs to be returned to the UE through the CU / DU. 3) for the APP downlink traffic through the UPF, the UPF needs to distinguish which is directly transmitted to the CU / DU to the UE and which needs to be processed by the SU. As shown in FIG. 8, the method can include steps 801-810, which are specifically as follows:

[0187] For steps 801-803, refer to steps 601-603 in Embodiment 2 shown in FIG. 6, which will not be repeated here.

[0188] 804, AIMF issues task configuration and data channel establishment indication.

[0189] For example, the AIMF issues the task configuration and data channel establishment indication to the SU, and the AIMF can also inform the SU through the CU. At the same time, the AIMF can optionally issue the cloud model configuration information to the APP server end. For this introduction, refer to the description of step 604 in Embodiment 2 shown in FIG. 6, which will not be repeated here.

[0190] 805a, the SU completes the local AI model configuration.

[0191] 805b, the APP server configures the APP-side AI model.

[0192] 806a, SU-CU data channel establishment.

[0193] After the SU completes the local model configuration, the SU initiates an AI task data channel establishment request (user plane / data plane) to the CU, indicates a double-end task / model, a double-end identifier, an AI QoS requirement of the channel, a transmission protocol, and the like, and the CU is responsible for mapping and shunting of the task data to the SU. For bidirectional transmission of the same data stream, the same or different data channels can be selected.

[0194] 806b, SU-APP data channel establishment.

[0195] The SU establishes an NG data channel with the UPF according to the indication of the AIMF (AMF and SMF participate). The SU matches the SU-CU data channel information with the NG data channel information, for mapping and forwarding, to realize uplink and downlink AI task interaction of the UE-APP.

[0196] Optionally, the matching and mapping and forwarding of the SU-CU data channel information with the NG data channel information can be performed after step 808, and the present scheme is not limited in this regard.

[0197] 807, air interface AI task bearer establishment.

[0198] According to the air interface AI bearer AI QoS issued, the base station and the UE complete RRC reconfiguration, establish a DRB (for each data stream) or a TRB (for each task, and the data type and AI QoS are distinguished according to the protocol layer header identifier); the CU or the DU realizes mapping and shunting of different bearers to tasks.

[0199] 808, the CU or the DU sends an AI session task response.

[0201] For example, after the air interface bearer is established, the CU feeds back to the SU, the SU feeds back complete session information to the AIMF, and thus the establishment of the network AI task is completed.

[0202] 810, start of AI task execution and data interaction.

[0203] This example gives an AI task data channel establishment process in a scenario where the end-to-end cloud jointly performs AI services, and the SU directly connects the APP through the UPF. In this example, the AI configuration indication and AI QoS configuration are added when the data channel is established, and the SU, the CU, and the UPF jointly perform data mapping, shunting, and forwarding.
