Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular, to a data transmission method, apparatus, and storage medium. Background Art

[0002] The application of artificial intelligence technology in the 5th Generation mobile communication technology (5G) network has promoted the intelligent development of mobile communication networks and vertical industries, but the application mode of "patching" and "plug-in" has hindered the exertion of the application effect of Artificial Intelligence (AI).

[0003] At the same time, the application exploration of artificial intelligence in all walks of life has put forward requirements for new basic capabilities of future networks. Facing the future vision of intelligent ubiquity, the 6th Generation mobile communication technology (6G) network needs to have built-in AI capabilities. The built-in AI of the 6G network requires the internal provision of a complete operating environment for the entire life cycle of AI workflows such as data collection, data preprocessing, model training, model inference, and model evaluation within the 6G network architecture, and deeply integrates the computing power, data, algorithms, connections, network functions, protocols, and processes required for AI services in the design. After the network supports built-in AI, the network environment will become more complex, and the signaling transmission volume and delay will increase significantly. Therefore, there is an urgent need for a data transmission method to improve network efficiency and performance. Summary of the Invention

[0034] Overview of the Quality of Service (QoS) system:

[0035] The 5G QoS characteristics define a set of characteristic parameters for each network node to process each QoS flow. The set of characteristic parameters is divided into standardized QoS characteristics and operator-specific QoS characteristics. Among them, the standardized QoS characteristics are associated with a fixed 5G QoS Identifier (5QI).

[0036] 5QI is a scalar used as a reference for 5G QoS characteristics, that is, an access node-specific parameter that controls the QoS forwarding processing of the QoS Flow.

[0037] The following content is described for 5QI in standard 23.501g70:

[0038] 1) 5G QoS characteristics. The 5G QoS characteristics associated with 5QI describe the end-to-end packet forwarding processing of the QoS Flow between the terminal and the UPF, and are specifically manifested as the following performance characteristics:

[0039] 1. Resource type (Non-Guaranteed Bit Rate (GBR), GBR, Delay-Critical GBR);

[0040] 2. Priority;

[0041] 3. Packet Error Rate;

[0042] 4. Packet Delay Budget (including Core Network Packet Delay Budget);

[0043] 5. Average Window (only applicable to GBR and Delay-Critical GBR resource types);

[0044] 6. Maximum Data Burst Capacity (only applicable to Delay-Critical GBR resource types).

[0045] 2) Standardized 5QI to QoS characteristic mapping. For services that are considered to be frequently used and optimized signaling through the use of standardized QoS characteristics, standardized 5QI values are specified. Dynamically allocated 5QI values (which require signaling of QoS characteristics as part of the QoS profile) can be used for services for which standardized 5QI values are not defined. The one-to-one mapping of standardized 5QI values to 5G QoS characteristics can be specified in Table 1. Among them, Table 1 only shows some examples.

[0046] Table 1

[0047]

[0048] In a Protocol Data Unit (PDU) session, there is a unique Quality of Service Flow Identifier (QoS Flow ID, QFI) used to identify the Quality of Service Flow (QoS Flow) (QFI corresponds one-to-one with 5QI, but this relationship is not excluded from being decoupled in future versions). 5G performs QoS guarantee based on QoS Flow, and the QoS Flow is controlled by the Service Management Function (SMF) entity and established or reconfigured through the PDU session establishment process and the PDU session modification process.

[0049] QoS Parameters:

[0050] The 5G core network configures Quality of Service parameters using QoS parameters to achieve QoS guarantee and control at different network nodes. The Quality of Service parameters include at least one of the following: Quality of Service control parameters adopted on the terminal side (denoted as QoS Rule), Quality of Service control parameters adopted on the base station side (denoted as QoS Profile), and Packet Detection Rules (PDR) adopted on the base station side.

[0051] Among them, 1) The QoS Profile is configured by the SMF to the base station through the Access and Mobility Management Function (AMF) using the N2 interface to implement QoS control on the base station side. 2) The QoS Rule and QoS parameters are coordinated by the SMF through the AMF to the terminal using the N1 interface, or the terminal implements QoS control on the terminal side by reflecting QoS. 3) The PDR is provided by the SMF to the User Plane Function (UPF), and QoS control is implemented at the UPF node.

[0052] The QoS control parameter QoS Profile used by the base station (gNB) is transmitted by the SMF through the AMF (using the PDU Session Resource Modify Request message and the PDU Session Resource Setup Request message) to the gNB. Each QoS Profile is associated with a QFI. The QoS Profile consists of 5QI, Allocation and Retention Priority (ARP), Reflective QoS Attribute (RQA), Guarantee Flow Bit Rate (GFBR), Maximun Flow Bit Rate (MFBR), notification control, and maximum packet loss rate parameters.

[0053] The QoS control parameter QoS Rule used by the terminal is for the terminal to perform the allocation and marking of uplink user plane data services (the QoS Rule associates the uplink data with the corresponding QoS Flow). The QoS Rule AMF is provided to the terminal explicitly through the session creation or adjustment process (PDU Session Establishment / Modification Procedure), or pre-configured or implicitly provided. The content of the QoS Rule includes: 1) the QFI of the QoS Flow associated with the QoS Rule; 2) the Packet Filter Set (PFS); 3) the relative priority value of the QoS Rule. In the uplink direction, when uplink data is generated: (1) the terminal compares the uplink data packet with the packet filter sets in multiple QoS Rules, and the comparison needs to be carried out in the order indicated by the precedence value until a QoS Rule that matches the data packet is found (the packet filter of this QoS Rule matches the uplink data packet); 2) if no matching QoS Rule is found, the packet is discarded; (3) the terminal uses the QFI corresponding to the matching QoS Rule to mark the user data and bundle it into the corresponding QoS Flow, and maps the QoS Flow to the radio air interface resources at the Service Data Adaptation Protocol (SDAP) layer; (4) the access network (including the base station) transfers the QoS Flow to the UPF through the N3 interface; (5) the UPF verifies whether the QFI value is associated with a QoS Rule sent to the terminal or whether it is derived from the reflected QoS by the terminal; (6) the UPF performs the Session Aggregate Maximum Bit Rate (Session-AMBR) operation of the session using the PDR and counts the packets for charging.

[0054] The QoS control parameter used by the UPF is the PDR. The content of the PDR includes: 1) the uplink or downlink data packet filter of the Service DataFlow template (SDF templat); 2) the PDR priority; 3) the QoS enforcement rules, such as the maximum bit rate of the Service Data Flow (SDF), the GFBR, and the maximum bit rate of the GBR QoS Flow; 4) the forwarding behavior rules; 5) the reflected QoS indication. The PDR is sent by the SMF to the UPF through the N4 session management (such as N4 Session Establishment or N4 Session Modification) process of N4.

[0055] Exemplarily, Figure 1 A schematic diagram of the classification and marking of user plane traffic and the mapping principle of QoS Flow to radio resources is provided.

[0056] Data flow mapping and QoS control process:

[0057] In the downlink direction, when downlink data arrives: 1) The work of the UPF includes classifying the data, marking it with QFI and performing QoS control, and forwarding it to the terminal. 2) The UPF uses the PDR to detect the user data flow and map it to the QoS Flow. 3) The UPF performs operations such as Session-AMBR and counts the packets for charging. 4) The UPF encapsulates the QFI and the activation indication information of the reflected QoS into the header information and transmits it to the Radio Access Network (RAN).

[0058] On the gNB side, the gNB maps the QoS Flow to the air interface radio resources through the RAN side rules (not a 1:1 mapping, and the mapping rules are determined by the SDAP layer of the base station), and performs QoS operations according to the QoS configuration.

[0059] In the uplink direction, when uplink data is generated: 1) The terminal uses the QFI corresponding to the matching QoS Rule to mark the user data and bundle it into the corresponding QoS Flow, and maps the QoS Flow to the air interface radio resources at the SDAP layer; 2) The access network transfers the QoS Flow to the UPF through the N3 interface; 3) The UPF verifies whether the QFI value is associated with a QoS Rule sent to the terminal or whether it is derived by the terminal from the reflected QoS; 4) The UPF uses the PDR to perform the Session-AMBR operation and counts the packets for charging.

[0060] The future network will be an intelligent network. Currently, the processing of AI mainly focuses on the cloud. However, for AI use cases specific to the air interface, such as CSI feedback optimization, beam management, and positioning, uploading a large amount of data from the terminal or RAN to the cloud will consume a large amount of resources and increase the interaction time. If the terminal and RAN also have the functions of data collection, model training, and model storage. That is, the entities for data collection, model training, and model storage can be the RAN or the terminal, then the overhead will be greatly reduced.

[0061] There may be the following scenarios for model transmission: The terminal requests an AI model, and the RAN sends the trained AI model to the terminal; The terminal requests to send a model and sends its own trained model to the RAN. The RAN requests an AI model, and the terminal sends the trained AI model to the base station; The RAN requests to send a model and sends its own AI model to the terminal; From the above processes, it can be seen that the RAN or the terminal needs to have a certain computing power, storage, and data processing capabilities. When the RAN sends the data generated by itself to the terminal, the interaction process for session establishment can be further simplified.

[0062] Exemplarily, as Figure 2 shown, taking the configuration of QoS-related parameters in the current standard session establishment process as an example, the terminal first sends a NAS message, that is, a PDU session establishment request (PDU Session Establishment Request) to the AMF. The AMF respectively performs SMF selection, PDU Session secondary authentication and authorization, the SMF performs PCF selection, the SMF performs UPF selection, and the SMF sends Namf_Communication_N1N2MessageTransfer to the AMF. It contains N2 SM information and N1 SMContainer information, which are sent to the RAN and the terminal respectively. In the following process, the QoS parameters are also transmitted in the following process:

[0063] QoS Profile: The QoS control parameters QoS Profile used by the gNB include 5QI, ARP, RQA, GFBR, MPLR, etc. It is transmitted by the SMF through the AMF using the N2 interface (PDU Session Resource Modify Request message and PDU Session Resource Setup Request message to the gNB).

[0064] QoS Rule: The QoS control parameter QoS Rule used by the terminal is for the terminal to perform the allocation and marking of uplink user plane data services (i.e., the QoS Rule associates the uplink data with the corresponding QoS Flow). The SMF provides the QoS Rule to the terminal explicitly through the AMF using the N1 interface PDUSession Establishment / Modification Procedure, or it can be pre-configured or provided implicitly.

[0065] PDR: The content of the QoS control parameter PDR used by the UPF includes 1) the uplink or downlink data packet filter of the SDF template; 2) the PDR priority; 3) the QoS enforcement rules, such as the maximum bit rate of the SDF, the maximum bit rate of the GFBR and GBR QoS Flows; 4) the forwarding behavior rules; 5) the reflected QoS indication. The SMF sends it to the UPF through the N4 Session management (such as N4 Session Establishment or N4 Session Modification) process of N4.

[0066] For future communication systems, with new data generated within the RAN such as AI, the network environment will be more complex, and the signaling transmission volume and latency will increase significantly. Therefore, there is an urgent need for a data transmission method to streamline the signaling interaction process to improve network efficiency and performance.

[0067] In view of this, the present disclosure proposes a data transmission method. The base station generates quality of service parameters, which include at least one of the following: the quality of service control parameters adopted on the terminal side, the quality of service control parameters adopted on the base station side, and the data packet detection rules adopted on the base station side. Compared with the related art where the core network element is responsible for generating and distributing these quality of service parameters, the present disclosure changes the generation source of these quality of service parameters, increases the parameters and types included in the quality of service parameters, and the base station generates and distributes these quality of service parameters, simplifying the signaling interaction process, reducing the number of signaling transmissions, and improving the network response speed.

[0068] The data transmission method provided by the embodiments of the present disclosure can be applied to systems of various communication standards. For example, the systems to which the data transmission method provided by the embodiments of the present disclosure can be applied include, but are not limited to, communication systems such as LTE systems, various versions evolved from LTE, and 5G systems. In addition, the method for sending and receiving system messages provided by the embodiments of the present disclosure can also be applied to future-oriented communication systems (such as 6G communication systems), etc.

[0069] In the embodiments of the present disclosure, the network architecture of a mobile communication network (including but not limited to 3G, 4G, 5G, and future mobile communication networks) may at least include a first communication node and a second communication node. It should be understood that, in this example, in the downlink, the first communication node may be a network-side device (such as, including but not limited to, a base station), and the second communication node may be a terminal-side device (such as, including but not limited to, a terminal). Of course, in the uplink, the first communication node may also be a terminal-side device, and the second communication node may also be a network-side device. In device-to-device communication between two communication nodes, both the first communication node and the second communication node may be base stations or terminals. The first communication node and the second communication node may be abbreviated as the first node and the second node respectively.

[0070] Exemplarily, taking the first communication node as a terminal and the second communication node as a base station as an example, as Figure 3 shown, a communication system provided by an embodiment of the present disclosure includes a terminal 10 and a base station 20. The terminal 10 and the base station 20 may be one or more, and the quantity is not limited.

[0071] In some embodiments, the base station 20 provides wireless access services for the terminal 10. One base station 20 provides at least one service coverage area (also referred to as a cell). The terminal 10 entering this area can communicate with the base station 20 through wireless signals to receive the wireless access services provided by the base station 20.

[0072] In some embodiments, the base station may be a base station in Long Term Evolution (LTE), Long Term Evolution Advanced (LTEA), or an evolved Node B (eNB or eNodeB), a base station device in a 5G network, or a base station in a future communication system, etc. The base station may include various macro base stations, micro base stations, home base stations, remote radio heads, reconfigurable intelligent surfaces (RISs), routers, relays, transmit receive points (TRPs), wireless fidelity (WIFI) devices, and other various network-side devices.

[0073] In some embodiments, the terminal may be a device with wireless transceiver functions. The terminal may be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver functions, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, and so on. The embodiments of the present disclosure do not limit the application scenarios. Sometimes, the terminal may also be referred to as a user, a user equipment (UE), an access terminal, a UE unit, a UE station, a mobile station, a mobile unit, a remote station, a remote terminal, a mobile device, a UE terminal, a wireless communication device, a UE agent, or a UE device, etc., and the embodiments of the present disclosure do not limit this.

[0074] It should be noted that Figure 3 is only an exemplary framework diagram, Figure 3 the number of devices included therein, and the names of each device are not limited, and in addition to Figure 3 the devices shown, the communication system may further include other devices, such as core network devices.

[0075] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and service scenarios described in the embodiments of the present disclosure are for more clearly explaining the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation to the technical solutions provided by the embodiments of the present disclosure. Those of ordinary skill in the art know that with the evolution of the network architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.

[0076] The embodiments of the present disclosure provide a data transmission method, which is applied to a base station, as Figure 4 shown, and the method includes the following steps:

[0077] S101. The base station generates quality of service parameters, and the quality of service parameters include at least one of the following: the quality of service control parameters adopted on the terminal side, the quality of service control parameters adopted on the base station side, and the data packet detection rules adopted on the base station side.

[0078] In some embodiments, the quality of service (QoS) control parameters adopted on the base station side may be referred to as QoS Profile, the QoS control parameters adopted on the terminal side may be referred to as QoS Rule, and the data packet detection rules adopted on the base station side may be referred to as PDR. There is no limitation in this regard.

[0079] In some embodiments, the QoS parameters are determined by the core network; alternatively, the QoS parameters are determined by the base station; alternatively, the QoS parameters are determined by the base station under the instruction of the core network.

[0080] In some embodiments, the QoS control parameters adopted on the base station side include QoS characteristic parameters, and the QoS characteristic parameters include at least one of the following: model size, number of model parameters, resource type; wherein, the resource type includes at least one of the following: first type, second type; wherein, the first type is a type related to artificial intelligence, and the second type is a type related to other services except communication services.

[0081] For example, the second type is an integrated service type, and the integrated service type here refers to a type related to other services except communication services, such as computing, sensing, and intelligent service types.

[0082] Among them, the two parameters of model size and number of model parameters are applicable to the type related to artificial intelligence and are used to characterize the size (unit: Mbyte) and number of parameters of the AI model.

[0083] Exemplarily, in order to adapt to the above embodiments, the protocol is modified for the 5G QoS characteristics related to 5QI. These characteristics describe the packet forwarding processing method between the UE and the UPF for the QoS Flow. After the modification, the specific performance characteristics are as follows:

[0084] 1. Resource type (non-GBR, GBR, delay-critical GBR, AI service);

[0085] 2. Priority;

[0086] 3. Packet delay budget (including the core network packet delay budget);

[0087] 4. Packet error rate;

[0088] 5. Average window (only applicable to GBR and delay-critical GBR resource types);

[0089] 6. Maximum data burst capacity (only applicable to delay-critical GBR resource types);

[0090] 7. Model size;

[0091] 8. Number of model parameters.

[0092] In some embodiments, the quality of service control parameters adopted on the base station side include computing power parameters.

[0093] In some embodiments, the computing power parameters include at least one of the following: data privacy level, floating point operations per second (FLOPS), and generalization performance parameter.

[0094] Among them, the data privacy level is that the base station determines the range of nodes with which the data can interact according to the sensitivity and privacy requirements of the data. Different data privacy levels represent different data transmission ranges and protection levels. According to the sensitivity and privacy requirements of the data, an appropriate data privacy level can be selected to ensure correct data processing and protection.

[0095] FLOPS characterizes at least one of the following: the computing power required per second for the current AI task, trillions of operations per second (TOPs), and multiply-accumulate operations (MACs). In this way, the base station can determine the computing power resources to be allocated to the service according to this FLOPS.

[0096] The generalization performance parameter is an index for evaluating the performance of a model in machine learning, and it characterizes the ability of the model to be general in different scenarios. The generalization performance parameter can help evaluate and select a model with better performance in practical applications.

[0097] In some embodiments, the base station can determine the nodes with which the data can interact according to the data privacy level. Among them, the options for the data privacy level include: data transmission only involves the UE and within the RAN (including OAM), UE internal data, and data transmission involves the UE, RAN, and CN. The definition of internal data is that the original data only exists within one or more entities, and encryption is required for external transmission or only the result data is externally transmitted.

[0098] In some embodiments, the generalization performance parameter is the proportion of the number of scenarios with a performance gain higher than a preset ratio to the total number of scenarios under different scenario combinations (for example: different deployments, different frequencies, indoor / outdoor, number of transceiver antennas, moving speed) compared to the reference value. For example, a total of 1000 models participate in the result evaluation, and finally 900 models have a performance gain higher than 0.9%, then the generalization performance parameter of this model is 900 / 1000 = 90%.

[0099] Exemplarily, based on the description of the above embodiments, the modification of the relevant configuration in the QoS profile in the protocol can be implemented as:

[0100] The QoS profile. A QoS Flow can be classified as "GBR" or "non - GBR" according to its QoS profile. The QoS profile of a QoS Flow sends its QoS parameters to the (R)AN, and it contains the following QoS parameters:

[0101] (1) For each QoS Flow, the QoS profile shall include the following QoS parameters: 5G QoS Identifier (5QI), Allocation and Retention Priority (ARP).

[0102] (2) Only for non - GBR QoS Flows, the QoS profile may also include the following QoS parameter: Reflected QoS Attribute (RQA).

[0103] (3) Only for GBR QoS Flows, the QoS profile shall include the following QoS parameters: Guaranteed Flow Bit Rate (GFBR) for uplink and downlink, Maximum Flow Bit Rate (MFBR) for uplink and downlink.

[0104] (4) Only for GBR QoS Flows, the QoS profile may also include one or more of the following QoS parameters: Notification control, Maximum Packet Loss Rate for uplink and downlink, FLOPS (Floating - Point Operations Per Second) / TOPs / MACs, Data Privacy Level, Generalized Performance Parameter.

[0105] It can be understood that as the functions of the base station expand from communication functions to support for functions such as intelligence, perception, and computing, the QoS Profile parameters and QoS characteristics also need to be expanded. After introducing AI services, it is necessary to specify the size of the model and the model parameters, which directly affect the required rate when the model is transmitted. In addition, since AI services require not only time - frequency - space - code - like resources, introducing the service quality control parameters adopted on the base - station side into computing power parameters, based on the computing power parameters, the base station can more accurately allocate computing resources for AI services, including processor performance, memory capacity, storage space, etc. By reasonably configuring and managing these resources, the efficient operation of AI services on the base - station side can be ensured, and the required computing requirements can be met.

[0106] S102. The base station establishes a data connection with the terminal based on the service quality parameters and conducts data transmission.

[0107] Among them, the data can be data of types such as text, image, audio, or video, or some new types of data, such as data related to artificial intelligence, data related to computing power, data related to perception, and data related to network data collection or management.

[0108] Based on this, compared with the related art where the core network element is responsible for generating and distributing these quality of service parameters, the present disclosure changes the generation source of these quality of service parameters, increases the parameters and types included in the quality of service parameters, and the base station generates and distributes these quality of service parameters, simplifies the signaling interaction process, reduces the number of signaling transmissions, and improves the network response speed. Moreover, the base station and the terminal can establish a data connection based on the quality of service parameters and perform data transmission, improving the data transmission efficiency.

[0109] For example, for QoS Profile and PDR, the base station can independently generate them according to the data generated by the base station under the indication of the core network, thus eliminating the signaling for the AMF to send the QoS Profile to the base station, and the base station undertakes part of the functions of the SMF and UPF, generates the PDR and performs downlink data packet filtering according to the PDR. In addition, the QoS Rule can also be directly sent by the base station to the terminal through the Radio Resource Control (RRC) signaling, instead of the AMF transmitting it to the UE through the NAS message, reducing the number of signaling transmissions and improving the network efficiency.

[0110] The embodiment of the present disclosure provides a data transmission method applied to a terminal, as Figure 5 shown, the method includes the following steps:

[0111] S201. During the process of establishing a data connection, the terminal receives the quality of service control parameters adopted by the terminal side sent by the base station, and the quality of service control parameters adopted by the terminal side belong to the quality of service parameters generated by the base station.

[0112] In some embodiments, the quality of service parameters further include at least one of the following: the quality of service control parameters adopted by the base station side, the data packet detection rules adopted by the base station side.

[0113] In some embodiments, the quality of service parameters are determined by the core network; or, the quality of service parameters are determined by the base station; or, the quality of service parameters are determined by the base station under the indication of the core network.

[0114] In some embodiments, the quality of service control parameters adopted by the base station side include quality of service characteristic parameters, and the quality of service characteristic parameters include at least one of the following: model size, number of model parameters, resource type; wherein, the resource type includes at least one of the following: the first type, the second type; wherein, the first type is a type related to artificial intelligence, and the second type is a type related to other services except communication services.

[0115] For example, the second type is the integrated service type, where the integrated service type refers to types related to other services except communication services, such as computing, sensing, and intelligent service types.

[0116] Exemplarily, to adapt to the above embodiments, the protocol is modified for 5G QoS characteristics related to 5QI. These characteristics describe the way of packet forwarding processing from the UE to the UPF for the QoS Flow. After modification, the specific performance characteristics are as follows:

[0117] 1. Resource type (non - GBR, GBR, latency - critical GBR, AI service);

[0118] 2. Priority;

[0119] 3. Packet delay budget (including core network packet delay budget);

[0120] 4. Packet error rate;

[0121] 5. Average window (only applicable to GBR and latency - critical GBR resource types);

[0122] 6. Maximum data burst capacity (only applicable to latency - critical GBR resource types);

[0123] 7. Model size;

[0124] 8. Number of model parameters.

[0125] Among them, the two parameters of model size and number of model parameters are applicable to types related to artificial intelligence, and are used to characterize the size (unit: Mbyte) and number of parameters of the AI model.

[0126] In some embodiments, the quality - of - service control parameters adopted by the base station include computing power parameters.

[0127] In some embodiments, the computing power parameters include at least one of the following: data privacy level, floating - point operations per second, and generalization performance parameters.

[0128] Among them, the content related to the computing power parameters can refer to the description of the content related to the computing power parameters in S101.

[0129] S202. The terminal performs data transmission with the base station based on the quality - of - service control parameters adopted on the terminal side.

[0130] Among them, the data can be data of types such as text, image, audio, or video, or some new types of data, such as data related to artificial intelligence, data related to computing power, data related to sensing, and data related to network data collection or management.

[0131] Based on this, during the process of establishing a data connection, the terminal receives the quality of service (QoS) control parameters adopted by the terminal side sent by the base station, and performs data transmission with the base station based on the QoS control parameters adopted by the terminal side. Compared with the related art where the QoS control parameters adopted by the terminal side are transparently transmitted to the terminal by the AMF through NAS messages, the number of signaling transmissions is reduced, and the network efficiency is improved.

[0132] Embodiments of the present disclosure provide another data transmission method. As Figure 6 shown, the method includes the following steps:

[0133] S301. The base station generates QoS parameters, where the QoS parameters at least include the QoS control parameters adopted by the terminal side.

[0134] Among them, the QoS parameters are determined by the core network; or, the QoS parameters are determined by the base station; or, the QoS parameters are determined by the base station under the indication of the core network.

[0135] In some embodiments, the QoS parameters further include at least one of the following: the QoS control parameters adopted by the base station side, the data packet detection rules adopted by the base station side.

[0136] S302. The base station sends a first message to the terminal; correspondingly, the terminal receives the first message sent by the base station; the first message is used to request the establishment of a data connection, and the first message includes the QoS control parameters adopted by the terminal side.

[0137] In some embodiments, the first message is carried in at least one of the following: Radio Resource Control (RRC) signaling, Media Access Control Control Element (MAC CE), Non-Access Stratum (NAS) message.

[0138] In some embodiments, the coding format of the first message is the TLV format. Among them, the TLV format is a data format based on Tag-Length-Value.

[0139] Among them, the PDR NAS signaling in the related art belongs to the TLV format. For simplicity, the first message can also be sent to the terminal by carrying the encapsulated NAS message in the RRC message.

[0140] S303. The terminal sends a second message to the base station; correspondingly, the base station receives the second message sent by the terminal; the second message is used to respond to the first message.

[0141] In some embodiments, the second message is carried in at least one of the following: RRC signaling, MAC CE, Downlink Control Information (DCI).

[0142] In some embodiments, the second message can also be carried in a NAS message. When the second message is carried in a NAS message instead of RRC signaling, the second message needs to be sent to the core network for annotation at the same time so as to execute subsequent processes.

[0143] S304. The base station and the terminal perform data transmission based on the quality of service control parameters adopted on the terminal side.

[0144] Among them, the data can be data of types such as text, image, audio or video, or can also be some new types of data, such as data related to artificial intelligence, data related to computing power, data related to perception, and data related to network data collection or management.

[0145] Based on this, carrying the quality of service control parameters adopted on the terminal side in the first message generated by the base station and directly sent to the terminal reduces the number of signaling transmissions and improves network efficiency compared with the related technology in which the AMF transmits the quality of service control parameters adopted on the terminal side to the UE through a NAS message.

[0146] The present disclosure provides another data transmission method. As Figure 7 shown, the method includes the following steps:

[0147] S401. The terminal sends a fourth message to the base station; correspondingly, the base station receives the fourth message sent by the terminal; the fourth message is used to request the establishment of a data connection.

[0148] In some embodiments, the fourth message is carried in at least one of the following: RRC signaling, MAC CE, DCI.

[0149] In some embodiments, the fourth message can also be carried in a NAS message. When the fourth message is carried in a NAS message instead of RRC signaling, the fourth message is sent to the core network for annotation so as to execute subsequent processes.

[0150] S402. The base station generates quality of service parameters, and the quality of service parameters at least include the quality of service control parameters adopted on the terminal side.

[0151] Among them, the quality of service parameters are determined by the core network; or, the quality of service parameters are determined by the base station; or, the quality of service parameters are determined by the base station under the indication of the core network.

[0152] In some embodiments, the quality of service parameter further includes at least one of the following: the quality of service control parameter adopted by the base station side, and the data packet detection rule adopted by the base station side.

[0153] S403. The base station sends a third message to the terminal; correspondingly, the terminal receives the third message sent by the base station; the third message is used to respond to the fourth message, and the third message includes the quality of service control parameter adopted by the terminal side.

[0154] In some embodiments, the third message is carried in at least one of the following: RRC signaling, MAC CE, and NAS message.

[0155] In some embodiments, the coding format adopted by the third message is the TLV format.

[0156] Among them, in the related art, the PDR NAS signaling belongs to the TLV format. For simplicity, the first message can also be sent to the terminal by carrying the encapsulated NAS message in the RRC message.

[0157] S404. The base station and the terminal perform data transmission based on the quality of service control parameter adopted by the terminal side.

[0158] Among them, the data can be data of types such as text, image, audio, or video, or some new types of data, such as data related to artificial intelligence, data related to computing power, data related to perception, and data related to network data collection or management.

[0159] It can be understood that if the transmission only involves the RAN and the UE, then only the RRC connection is required, and the N2 connection becomes optional. That is, when the RAN and the UE perform internal data transmission, only the RRC connection can be established, or both the RRC connection and the N2 connection can be established.

[0160] Based on this, carrying the quality of service control parameter adopted by the terminal side in the third message generated by the base station and directly sending it to the terminal reduces the number of signaling transmissions and improves network efficiency compared with the related art in which the AMF transparently transmits the quality of service control parameter adopted by the terminal side to the UE through the NAS message.
