[0071] To help those skilled in the art better understand the technical solutions of the embodiments of the present disclosure, the technical solutions of the present disclosure will be clearly and completely described below in conjunction with the drawings in the present disclosure. Obviously, the embodiments described are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0072] It should be noted that in this disclosure, words such as "exemplarily" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this disclosure as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a concrete manner.

[0073] In the following, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Therefore, a feature defined with the terms "first," "second," etc., may explicitly or implicitly include one or more of such features.

[0074] In the description of this disclosure, unless otherwise specified, " / " means "or." For example, A / B can mean A or B. "And / or" herein is merely a description of an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: only A, only B, and both A and B. Furthermore, "at least one" means one or more, and "a plurality" means two or more.

[0075] The method provided by the embodiment of the present disclosure can be applied to various communication systems. For example, the communication system can be a fifth generation (5G) communication system, a Wi-Fi system, a 3GPP (3rd Generation Partnership Project) related communication system, a future evolved communication system (such as a sixth generation (6G) communication system, etc.), or a system integrating multiple systems, etc., without limitation. The method provided by the embodiment of the present disclosure is described below using the communication system 100 shown in Figure 1 as an example. Figure 1 is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the technical solution provided by the present disclosure.

[0076] As shown in FIG1 , the communication system 100 includes a first node 110 and a second node 120 , wherein the first node 110 and the second node 120 are in communication connection.

[0077] The first node 110 is used for communication, information acquisition, and entertainment. In some embodiments, the first node 110 is used to send a first message to the second node 120 (the first message is used to request the transmission of first-type data), receive a second message sent by the second node 120 in response to the first message, and transmit the first-type data with the second node 120 based on the second message.

[0078] In some embodiments, one of the first node 110 and the second node 120 is a transmission starting point for the first type of data, and the other of the first node 110 and the second node 120 is a transmission ending point for the first type of data.

[0079] In some embodiments, the communication system 100 further includes a target node (not shown). The first node 110 is further configured to send a fourth message to the target node (the fourth message is used to request establishment of a session for transmitting the first type of data), receive a fifth message sent by the target node indicating completion of session establishment, and transmit the first type of data with the target node.

[0080] Second node 120 is configured to exchange and communicate data. In some embodiments, second node 120 is configured to receive a first message sent by first node 110, send a second message to first node 110 in response to the first message, and transmit first-type data to first node 110 based on the second message.

[0081] In some embodiments, one of the first node and the second node is a base station, and the other of the first node and the second node is a terminal. The terminal can be a user equipment (UE), such as a mobile phone, tablet computer, desktop computer, laptop computer, handheld computer, notebook computer, ultra-mobile personal computer (UMPC), netbook computer, or cellular phone. The first node 110 can also be an augmented reality (AR) or virtual reality (VR) device. The base station can be a base station (gNB) in a 5G system using a centralized distributed architecture, or a base station in a 6G system.

[0082] In some embodiments, a wireless connection may be established between the first node 110 and the second node 120 via a wireless air interface. In various implementations, the wireless air interface may be a wireless air interface based on the 4G standard; or, the wireless air interface may be a wireless air interface based on the 5G standard, such as a new air interface; or, the wireless air interface may be a wireless air interface based on a next-generation mobile communication network technology standard of 5G.

[0083] The target node is used to receive the fourth message sent by the first node 110 (the fourth message is used to request to establish a session for transmitting the first type of data), send a fifth message to the first node, and transmit the first type of data with the first node through the session.

[0084] In some embodiments, the target node may be a base station or an operation administration and maintenance (OAM) device. The embodiment of the present disclosure does not limit the form of the target node.

[0085] It should be noted that the system architecture and application scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0086] The future network will be an intelligent network. Currently, the processing of data related to some artificial intelligence technologies (for example, data involved in AI air interface transmission models, perception data, etc.) is mainly concentrated in the cloud. That is, the data will be uploaded to the cloud via the terminal (for example, UE) and base station (for example, RAN) for processing.

[0087] The AI ​​air interface transmission model described above utilizes artificial intelligence technology to model, predict, and optimize wireless communication channels. This model can analyze large amounts of wireless channel data using deep learning algorithms, thereby improving the efficiency and performance of wireless communication systems. The AI ​​air interface transmission model enables a better understanding and utilization of wireless channels, thereby enhancing the reliability and throughput of communication systems. In wireless communication systems, since AI air interface transmission models typically need to be stored and deployed in different locations, model transfer and delivery are crucial. In this case, model transfer may involve migrating from a server to an access network or a third-party entity (such as an over-the-top (OTT) server). Appropriate model transfer and delivery strategies can ensure that the model can be effectively deployed and used when needed, thereby improving the performance and efficiency of the communication system. This also requires comprehensive consideration of factors such as network bandwidth, latency, and security to ensure model reliability and availability. For example, Figure 2 shows the functional architecture of the AI ​​air interface transmission model. This functional architecture includes modules such as data acquisition, model training, model management, model inference, and model storage. In this functional architecture, after collecting the data involved in the AI ​​air interface transmission model, the model can be trained, managed, and inferred by training, managing, and inferring the data, and finally stored.

[0088] However, air-interface-specific AI use cases often require real-time processing of large amounts of data. Uploading this massive amount of data to the cloud for processing will consume significant network bandwidth and resources, leading to network congestion and increased latency. Furthermore, because air-interface-specific AI use cases require high real-time data processing, uploading data to the cloud for processing will cause round-trip data transmission, increasing data interaction latency. In summary, uploading data to the cloud for processing for air-interface-specific AI use cases will result in significant overhead in data transmission and processing.

[0089] Therefore, if the terminal and the base station also have the functions of data transmission and processing (for example, data collection, model training and model storage), that is, the entity for data transmission and processing can be the terminal or the base station, the overhead in the data transmission and processing process will be reduced. The data transmission scenarios may be: the terminal requests data (for example, data related to the AI ​​air interface transmission model), and the base station sends the trained AI model to the terminal; or, the terminal requests to send data (for example, data related to the AI ​​air interface transmission model), and the terminal sends its own trained AI model to the base station; or, the base station requests data (for example, data related to the AI ​​air interface transmission model), and the terminal sends its own trained AI model to the base station; or, the base station requests to send data (for example, data related to the AI ​​air interface transmission model), and the base station sends its own trained AI air interface transmission model to the terminal. To implement the examples in the above scenarios, the access network architecture needs to have certain capabilities. For example, the terminal and the base station need to have a certain amount of computing power, storage, and data processing capabilities. The data processing here includes the mapping of AI air interface transmission model data files / streams->quality of service (QoS) flows->data radio bearers (DRBs), or the mapping of AI air interface transmission model data files / streams->DRBs and data fragmentation processing. These new functions may be included in the functional entities of the existing air interface protocol stack or may be implemented through new functional entities. In addition, the protocol stacks of the terminal and the base station must also support the starting and ending points of data transmission as the terminal and the base station. However, in the current protocol stack, after the data is sent to the base station through the terminal, the base station will further send it to the user plane function (UPF), so that the data is not only transmitted and processed between the terminal and the base station. For example, Figure 3 is a transmission flow chart of data (such as data related to the AI ​​air interface transmission model). Based on Figure 3, it can be seen that in the current protocol stack, after the data is transmitted from the UE to the 5G access network (5G access network, 5G-AN), the transmission does not stop, but continues to be transmitted to the UPF.

[0090] For the above problem, see Figure 4. Figure 4 is a flow chart of a data transmission method provided by an embodiment of the present disclosure. As shown in Figure 4, the data transmission method provided by an embodiment of the present disclosure is applied to a first node and includes the following S101-S103.

[0091] S101. Send a first message to a second node.

[0092] The first message is used to request transmission of first type data.

[0093] In some embodiments, the first message includes at least one of the following: data size, data type. For example, the first message includes: data size is 1MB, and data type is the first type.

[0094] In some embodiments, the data type further includes a second type, that is, in addition to the first type of data, the second type of data also exists. The second type of data is traditional communication data. Optionally, the traditional communication data can be one or more of voice data, text data, image data, video data, and file data. The embodiments of this disclosure do not limit the specific content of the second type of data.

[0095] It should be noted that the content included in the above-mentioned first message is only some examples given in the embodiment of the present disclosure. During implementation, the content included in the first message may vary according to different actual conditions, and the embodiment of the present disclosure does not limit this.

[0096] In some embodiments, the first message is indicated by at least one of radio resource control (RRC) signaling, a medium access control control element (MAC CE), and downlink control information (DCI).

[0097] In some embodiments, the first type of data includes at least one of the following: data generated and / or used by artificial intelligence AI, and perception data.

[0098] It should be noted that the types of the above-mentioned first type of data are only some examples given in the embodiments of the present disclosure. In actual implementation, the types of the first type of data may be more or less than the types given in the above examples. The embodiments of the present disclosure do not limit the types and contents of the first type of data.

[0099] In some embodiments, one of the first node and the second node is a base station, and the other of the first node and the second node is a terminal.

[0100] It can be understood that when the first node needs to transmit the first type of data to the second node, it will send a first message to the second node so that the first node establishes an association with the second node. At the same time, one of the first node and the second node is a base station, and the other of the first node and the second node is a terminal. The first type of data can be transmitted between the base station and the terminal without the need to be further uploaded to the cloud for processing, thereby avoiding the occupation of network bandwidth and resources when the first type of data is uploaded to the cloud, and avoiding the problem of excessive interaction delay caused by round-trip transmission when processing the first type of data, thereby reducing the overhead in the transmission and processing of the first type of data.

[0101] S102: Receive a second message sent by a second node to respond to the first message.

[0102] In some embodiments, after receiving the first message, the second node generates a second message to respond to the first message based on the content of the first message, and sends the second message to the first node, so that the first node determines that the second node agrees to transmit the first type of data based on the second message.

[0103] In some embodiments, the second message is indicated by at least one of RRC signaling, MAC CE, and DCI.

[0104] It can be understood that when the first node needs to transmit the first type of data to the second node, after sending the first message to the second node, it will receive the second message from the second node in response to the first message to confirm the transmission of the first type of data, so that the first node can perform subsequent operations based on the second message (that is, the feedback message from the second node), thereby ensuring the reliability of the first type of data transmission.

[0105] S103: Transmit the first type of data with the second node based on the second message.

[0106] In some embodiments, the above S103 may be implemented as: transmitting the first type of data to the second node via a radio bearer between the first node and the second node.

[0107] As an example, the second message includes radio bearer configuration information. When the first node receives the second message, it can establish a radio bearer with the second node based on the radio bearer configuration information, and transmit the first type of data to the second node through the radio bearer. After the radio bearer is established, it can be determined that one of the first node and the second node is the starting point for transmission of the first type of data, and the other of the first node and the second node is the end point for transmission of the first type of data, that is, the first type of data will not be further transmitted to the cloud. In some embodiments, the above-mentioned radio bearer is a radio bearer dedicated to the first type of data, that is, the radio bearer is used to transmit the first type of data.

[0108] In some embodiments, the radio bearer is a data radio bearer (DRB) or a signaling radio bearer (SRB). Whether the radio bearer is a DRB or an SRB can be determined based on the amount of the first type of data. For example, if the amount of the first type of data is greater than a threshold, the radio bearer is a DRB; or, if the amount of the first type of data is less than or equal to the threshold, the radio bearer is an SRB. Optionally, the threshold may be 10MB.

[0109] As another example, before the first node sends the first message to the second node, the method further includes: establishing a radio bearer with the second node. That is, when there is a need to transmit first-type data between the first node and the second node, the first node may first establish a radio bearer with the second node and then send the first message to the second node. After receiving the second message from the second node, the first node may then transmit the first-type data to the second node via the radio bearer.

[0110] It should be noted that in the embodiments of the present disclosure, a radio bearer can be established either before the first node sends the first message or before the first node transmits the first type of data to the second node. In other words, the time to establish the radio bearer can depend on the data transmission requirements between the first node and the second node. The embodiments of the present disclosure do not impose a limit on the time to establish the radio bearer, thereby increasing the flexibility of radio bearer establishment.

[0111] In some embodiments, a radio bearer is configured to transmit first-type data between a first node and a second node. That is, one of the first node and the second node is the starting point for transmission of the first-type data, and the other of the first node and the second node is the end point for transmission of the first-type data. Therefore, when the first node transmits first-type data to the second node via the radio bearer, the first-type data is transmitted only between the first node and the second node and does not flow to other nodes.

[0112] It can be understood that based on the data transmission method provided in the embodiment of the present disclosure, when the first node needs to transmit the first type of data to the second node, it will send a first message to the second node and receive a second message from the second node to respond to the first message, so as to realize the confirmation of the transmission of the first type of data, so that the first node can perform subsequent operations based on the second message (i.e., the feedback message of the second node), thereby ensuring the reliability of the first type of data transmission.

[0113] At the same time, in the method provided by the embodiment of the present disclosure, when the first node and the second node transmit the first type of data, one of the first node and the second node is the transmission starting point of the first type of data, and the other of the first node and the second node is the transmission end point of the first type of data; the first type of data does not need to be further transmitted to the cloud for processing, but is only transmitted between the first node and the second node, which improves the efficiency of the transmission and processing of the first type of data and reduces the overhead during the transmission and processing of the first type of data.

[0114] In some embodiments, as shown in FIG5 , after transmitting the first type of data with the second node, the method further includes: S104 - S105 .

[0115] S104: Receive a third message sent by the second node.

[0116] In some embodiments, the third message is used to indicate that the transmission of the first type of data is complete. After the first node and the second node complete the transmission of the first type of data (for example, after the first node receives all of the first type of data), the second node sends the third message to the first node to enable the first node to determine that the transmission of the first type of data is complete.

[0117] In some embodiments, the third message is indicated by at least one of RRC signaling, MAC CE, and DCI.

[0118] It can be understood that after the first type of data transmission is completed, the first node can receive the third message sent by the second node in the method provided in the embodiment of the present disclosure, so that the first node and the second node can perceive the transmission status of the first type of data in a timely manner.

[0119] S105: Based on the third message, release the radio bearer used to transmit the first type of data.

[0120] As an example, when the first node receives the third message and determines that the first type of data has been transmitted, the first node may release the radio bearer used to transmit the first type of data. As another example, when the first node is in an inactive state or an idle state, the first node determines that the first type of data has been transmitted, and the first node may release the radio bearer.

[0121] It can be understood that the method provided by the embodiment of the present disclosure is based on establishing a wireless bearer between the first node and the second node, and based on the wireless bearer, transmitting the first type of data, thereby ensuring the transmission starting point and transmission end point of the first type of data, and avoiding the problem that the first type of data will be further transmitted to the cloud, causing pressure on the cloud.

[0122] It should be noted that in S103 above, the original protocol stacks of the first node and the second node are not modified. Instead, the first type of data is transmitted between the first node and the second node based on the radio bearer. In actual operation, the original protocol stacks of the first node and the second node may also be modified to enable the transmission of the first type of data between the first node and the second node.

[0123] As an implementation method, a new functional layer can be added on top of the original protocol stack of the first node and the second node, that is, a new functional layer (for example, an AI protocol layer, a perception protocol layer, etc.) is configured for the first type of data to ensure that the first type of data is transmitted between the first node and the second node.

[0124] In some embodiments, as shown in Figure 6, the protocol stacks of the first node and the second node include a first functional layer for generating and / or processing first type data, a second functional layer for generating and / or processing second type data, a physical layer shared by the first and second functional layers, and a data link layer shared by the first and second functional layers. The first functional layer is a new functional layer configured for the first type data; the second functional layer is a traditional functional layer in the original protocol stack.

[0125] It can be understood that the method provided by the embodiment of the present disclosure adds a new functional layer on top of the original protocol stack of the first node and the second node, so that the first type of data can be transmitted through the new functional layer, that is, it ensures that the first type of data is transmitted between the first node and the second node.

[0126] As another implementation, in addition to adding a functional layer to the existing protocol stacks of the first and second nodes, an independent protocol stack can also be configured for the first type of data. For example, the application layer, data link layer, and physical layer used by the first type of data all adopt new functional layers that are completely independent of the existing protocol stack, thereby enabling the first type of data to be transmitted between the first and second nodes. Optionally, a portion of the data link layer's functions can be implemented in the new functional layer, while another portion of the data link layer's functions are shared with the functional layers of the existing protocol stack; and a portion of the physical layer's functions can be implemented in the new functional layer, while another portion of the physical layer's functions are shared with the functional layers of the existing protocol stack.

[0127] In some embodiments, as shown in Figure 7, the first node and the second node have a first protocol stack for first-type data and a second protocol stack for second-type data. The first protocol stack includes a first functional layer, a first data link layer, and a first physical layer, and the second protocol stack includes a second functional layer, a second data link layer, and a second physical layer. The second-type data is traditional communication data. The first protocol stack is an independent protocol stack configured for the first-type data.

[0128] It can be understood that, based on the difference between the first type of data and the second type of data, the embodiment of the present disclosure configures a first protocol stack for the first type of data, so that the first type of data is transmitted on the first protocol stack, ensuring that the transmission starting point and transmission end point of the first type of data are the first node and the second node.

[0129] As an example, the first functional layer is the user plane functional layer. As shown in Figure 8, the functions of the user plane functional layer include at least one of the following: data collection, data transmission, and data processing. In this case, the user plane functional layer is similar to the application layer in a traditional protocol stack.

[0130] As another example, the first functional layer is a control plane functional layer. As shown in Figure 9, the functions of the control plane functional layer include at least one of the following: connection control, parameter configuration, model training, and model inference. In this case, the control plane functional layer is similar to the RRC function in a traditional protocol stack.

[0131] In some embodiments, the packet header of the first type of data includes indication information for indicating that the first type of data is transmitted to the first functional layer or the second functional layer. The indication information is indicated by at least one of a preset identifier and the address of the transmission endpoint. As an example, as shown in Figure 10, an N-bit indication can be added to the packet header of the indication information to indicate that the first type of data is sent to the first functional layer or the second functional layer. In some embodiments, the value of N is related to the number of data outlets. For example, if the number of outlets is 2, N is 1; if the number of outlets is 4, N is 2. Exemplarily, taking N as 1 as an example, if N is 1, the indication is 1, indicating that the first type of data is transmitted to the first functional layer; if N is 1, the indication is 0, indicating that the first type of data is transmitted to the second functional layer.

[0132] As another example, as shown in Figure 11, an address may be added to the header of the indication information to indicate whether the first type of data is sent to the first functional layer or the second functional layer. For example, if the address in the header of the indication information is the address of the first functional layer, then the first type of data is sent to the first functional layer.

[0133] It can be understood that the method provided by the embodiment of the present disclosure adds indication information to the packet header of the first type of data, so that the second node can determine the transmission path of the first type of data based on the indication information after receiving the first type of data, thereby ensuring that the first type of data is transmitted between the first node and the second node.

[0134] In some embodiments, in addition to determining the transmission direction of the first type of data based on the indication information in the first type of data packet header, the transmission direction of the first type of data may also be determined based on the radio bearer between the first node and the second node. For example, if the radio bearer between the first node and the second node is a radio bearer in the original protocol stack, the first type of data is sent to the second functional layer; if the radio bearer between the first node and the second node is a special radio bearer based on the original traditional protocol stack (when configuring the special radio bearer, the protocol function layer used by the special radio bearer is also configured, for example, the protocol function layer used by the special radio bearer includes the first functional layer), the first type of data is sent to the first functional layer.

[0135] Based on the architecture of the aforementioned protocol stack, the transmission of the first type of data begins and ends at the first functional layer. For example, the first type of data can be sent from a first node to a second node, and the second node can determine the flow direction of the first type of data by parsing the indication information in the first type of data packet header. For another example, after the first functional layer of the first node generates the first type of data, it can send the generated first type of data to the second node based on an event trigger or periodically. Optionally, after the first functional layer generates the first type of data, it can send the first type of data to the second node every 5 seconds.

[0136] As another implementation method, in the method provided by the above-mentioned disclosed embodiment, the flow direction of the first type of data is fixed. For example, the first type of data is transmitted along the physical layer (PHY)->media access control layer MAC->radio link control layer (RLC)->packet data convergence protocol layer (PDCP)->service data adaptation protocol (SDAP)->UPF or along PHY->MAC->RLC->PDCP->SDAP->AI. However, as the functions of the communication system become more and more complex, the starting point and end point of data transmission are also more variable, and the original protocol stack cannot meet the needs of data transmission and processing. Therefore, a more flexible mapping can be introduced into the protocol stack architecture, that is, each protocol layer can flexibly determine the address of the next hop so that the first type of data is transmitted between the first node and the second node. Optionally, a more refined functional component can be used to replace the protocol layer, and the next hop address of the component can be used instead of the next hop address of each protocol layer.

[0137] It can be understood that in order to adapt to the functions of more complex communication systems, the method provided in the embodiments of the present disclosure introduces a more flexible mapping in the protocol stack architecture, which allows each protocol layer to flexibly determine the address of the next hop, so as to flexibly determine the transmission starting point and transmission end point of the first type of data.

[0138] In some embodiments, the first type of data is transmitted via a radio bearer, and the configuration information of the radio bearer includes indication information for indicating each protocol layer used by the radio bearer. That is, the second information received by the first node includes the configuration information of the radio bearer; the first node can provide indication information for each protocol layer used by the radio bearer to determine the transmission path of the first type of data. For example, as shown in Figure 12, in the flexible protocol stack, the configuration information of the radio bearer indicates that the protocol layers used by the radio bearer are F4->F3->F2'->F1' in sequence. Then, when the first node and the second node transmit the first type of data, the configuration information of the radio bearer is used to transmit the first type of data.

[0139] As another implementation, the first type of data and the second type of data may share the same protocol stack, i.e., no new functional layer is added to the existing protocol stack, nor is a new protocol stack configured for the first type of data. In this case, the protocol stacks of the first node and the second node include a third functional layer, a third physical layer, and a third data link layer for generating and / or processing the first type of data and the second type of data.

[0140] 13 is a flowchart of a data transmission method provided by an embodiment of the present disclosure. As shown in FIG13 , the data transmission method provided by an embodiment of the present disclosure is applied to the second node and can be implemented as follows S201-S203.

[0141] S201: Receive a first message sent by a first node.

[0142] In some embodiments, the first message is used to request transmission of a first type of data.

[0143] In some embodiments, before receiving the first message sent by the first node, the method further includes: establishing a radio bearer with the first node.

[0144] S202: Send a second message to the first node in response to the first message.

[0145] S203: Transmit the first type of data with the first node based on the second message.

[0146] In some embodiments, one of the first node and the second node is a transmission starting point for the first type of data, and the other of the first node and the second node is a transmission ending point for the first type of data.

[0147] In some embodiments, as shown in FIG14 , after transmitting the first type of data with the first node based on the second message, the method further includes: S204 - S205 .

[0148] S204: Send a third message to the first node.

[0149] In some embodiments, the third message is used to indicate that the first type of data transmission is completed.

[0150] S205: Based on the third message, release the radio bearer used to transmit the first type of data.

[0151] In some embodiments, the implementation of the above S201-S204 may refer to the above S101-S105, and the embodiments of the present disclosure will not be repeated here.

[0152] It can be understood that based on the data transmission method provided in the embodiment of the present disclosure, after receiving the first message sent by the first node, the second node sends a second message to the first node to respond to the first message, so as to realize the confirmation of the transmission of the first type of data, so that the first node can perform subsequent operations based on the second message (i.e., the feedback message of the second node), thereby ensuring the reliability of the first type of data transmission.

[0153] At the same time, in the method provided by the embodiment of the present disclosure, when the second node and the first node transmit the first type of data, one of the first node and the second node is the transmission starting point of the first type of data, and the other of the first node and the second node is the transmission end point of the first type of data, so that the first type of data is only transmitted between the first node and the second node, that is, the first type of data does not need to be further uploaded to the cloud for processing, thereby avoiding the occupation of network bandwidth and resources when the first type of data is uploaded to the cloud, and avoiding the problem of excessive interaction delay caused by round-trip transmission when processing the first type of data, thereby reducing the overhead in the transmission and processing of the first type of data.

[0154] The above disclosed embodiments mainly introduce an example of transmitting the first type of data between the first node and the second node. However, in actual implementation, the first type of data may not be limited to being transmitted between the first node and the second node, and the transmission starting point and transmission end point of the first type of data may be flexibly determined according to different actual conditions.

[0155] To address the above issues, see Figure 15, which is a flow chart of a data transmission method provided by an embodiment of the present disclosure. As shown in Figure 15, the data transmission method provided by an embodiment of the present disclosure is applied to a first node and can be implemented as follows S301-S303.

[0156] S301. Send a first message to a second node.

[0157] In some embodiments, the first message is used to request transmission of a first type of data.

[0158] S302: Receive a second message sent by a second node to respond to the first message.

[0159] In some embodiments, the second message includes the address information of the target node. That is, after the first node sends the first message to the second node, the second node can match a suitable target node for the first node based on the content of the first message, such as the amount of the first type of data, and place the address of the target node in the second message and send it to the first node.

[0160] In some embodiments, the first node and the second node are two different nodes among a terminal, a radio access network (RAN) element, a core network (CN) element, and a server. For example, the first node may be a terminal, and the second node may be a CN element. When the terminal needs to transmit data to or from the CN element, the terminal sends a first message to the CN element and receives a second message sent by the CN element in response to the first message, thereby confirming the data before transmission.

[0161] In some embodiments, the target node is the second node; or, the target node is another node different from the second node. Exemplarily, the second message includes address information of the second node, or the second message includes address information of another node different from the second node.

[0162] In some embodiments, the target node is any one of a terminal, a RAN network element, a CN network element, and a server, and the target node and the first node are of different node types. For example, the first node may be a RAN network element, and the target node may be a CN network element.

[0163] In some embodiments, the implementation of the above S301-S302 may refer to the above S101-S102, and the embodiments of the present disclosure will not be repeated here.

[0164] It can be understood that based on the data transmission method provided by the embodiment of the present disclosure, when the first node needs to transmit the first type of data, it will send a first message to the second node and receive a second message from the second node in response to the first message to confirm the transmission of the first type of data, so that the first node can perform subsequent operations based on the second message (that is, the feedback message of the second node), thereby ensuring the reliability of the first type of data transmission. At the same time, with the complexity of the functions of the communication system, the starting point and end point of data transmission are also more variable. In the method provided by the embodiment of the present disclosure, the target node is the second node; or the target node is a node other than the second node, so that the type of target node is more diverse, and the transmission starting point and transmission end point of the first type of data are more flexible to adapt to the functions of more complex communication systems.

[0165] S303: Transmit the first type of data with the target node based on the address information of the target node.

[0166] In some embodiments, one of the first node and the destination node is a transmission starting point for the first type of data, and the other of the first node and the destination node is a transmission termination point for the first type of data. Exemplarily, the first node, based on the address information of the destination node, serves as the transmission starting point for the first type of data and sends the first type of data to the destination node.

[0167] In some embodiments, as shown in FIG16 , the above S303 may be implemented as: S3031 - S3033 .

[0168] S3031. Send a fourth message to the target node based on the address information of the target node.

[0169] In some embodiments, the fourth message is used to request establishment of a session for transmitting the first type of data. That is, when the first node needs to transmit the first type of data with the target node, the fourth message is sent to the target node so that the target node responds to the fourth message.

[0170] In some embodiments, the fourth message is indicated by at least one of RRC signaling, MAC CE, and DCI.

[0171] S3032. Receive the fifth message sent by the target node.

[0172] In some embodiments, the fifth message is used to indicate that the session establishment is complete. That is, when the first node receives the fifth message sent by the target node, it can be determined that the session between the first node and the target node is now established. At this time, the first node can transmit the first type of data with the target node based on the session.

[0173] In some embodiments, the fifth message is indicated by at least one of RRC signaling, MAC CE, and DCI.

[0174] S3033. Transmit the first type of data with the target node through the session.

[0175] It is understandable that in the method provided by the embodiment of the present disclosure, the first node can obtain the address information of the target node from the second node, and based on the address information of the target node, transmit the first type of data with the target node, which can make the transmission starting point and transmission end point of the first type of data transmission more abundant. In addition, one of the first node and the target node is the transmission starting point of the first type of data, and the other of the first node and the target node is the transmission end point of the first type of data. The first type of data is only transmitted and processed between the first node and the target node, that is, the first type of data does not need to be further uploaded to the cloud for processing, which avoids the occupation of network bandwidth and resources when the first type of data is uploaded to the cloud, and avoids the problem of excessive interaction delay caused by round-trip transmission when processing the first type of data, thereby reducing the overhead in the transmission and processing of the first type of data.

[0176] 17 is a flowchart of a data transmission method provided by an embodiment of the present disclosure. As shown in FIG17 , the data transmission method provided by an embodiment of the present disclosure is applied to the second node and can be implemented as follows S401-S402.

[0177] S401: Receive a first message sent by a first node.

[0178] In some embodiments, the first message is used to request transmission of a first type of data.

[0179] S402: Send a second message to the first node in response to the first message.

[0180] In some embodiments, the second message includes address information of the target node; wherein, one of the first node and the target node is a transmission starting point for the first type of data, and the other of the first node and the target node is a transmission ending point for the first type of data.

[0181] In some embodiments, the implementation of the above S401-S402 may refer to the implementation of the above S201-S202, and the embodiments of the present disclosure will not be repeated here.

[0182] It can be understood that based on the data transmission method provided in the embodiment of the present disclosure, after receiving the first message sent by the first node, the second node sends a second message to the first node to respond to the first message, so as to realize the confirmation of the transmission of the first type of data, so that the first node can perform subsequent operations based on the second message (i.e., the feedback message of the second node), thereby ensuring the reliability of the first type of data transmission.

[0183] At the same time, the second message includes the address information of the target node, which enables the first node to transmit the first type of data to the target node, thereby enriching the transmission starting point and transmission end point of the first type of data transmission. In addition, one of the first node and the target node is the transmission starting point of the first type of data, and the other of the first node and the target node is the transmission end point of the first type of data, ensuring that the first type of data is only transmitted and processed between the first node and the target node. That is, the first type of data does not need to be further uploaded to the cloud for processing, avoiding the occupation of network bandwidth and resources when uploading the first type of data to the cloud, and avoiding the problem of excessive interaction delay caused by round-trip transmission when processing the first type of data, thereby reducing the overhead during the transmission and processing of the first type of data.

[0184] 18 is a flowchart of a data transmission method provided by an embodiment of the present disclosure. As shown in FIG18 , the data transmission method provided by an embodiment of the present disclosure is applied to a target node and can be implemented as follows S501-S503.

[0185] S501: Receive a fourth message sent by a first node.

[0186] In some embodiments, the fourth message is used to request establishment of a session for transmitting the first type of data.

[0187] S502: Send a fifth message to the first node.

[0188] In some embodiments, the fifth message is used to indicate that the session establishment is complete.

[0189] S503: Transmit first type data with the first node through a session.

[0190] In some embodiments, one of the first node and the target node is a transmission starting point for the first type of data, and the other of the first node and the target node is a transmission ending point for the first type of data.

[0191] In some embodiments, the implementation of the above S501-S503 may refer to the implementation of the above S301-S302, and the embodiments of the present disclosure will not be repeated here.

[0192] It can be understood that, based on the data transmission method provided in the embodiment of the present disclosure, after the target node receives the fourth message sent by the first node (the fourth message is used to request the establishment of a session for transmitting the first type of data), it sends a fifth message to the first node (the fifth message is used to indicate that the session establishment is complete) to confirm the transmission of the first type of data and establish a session for transmitting the first type of data, so that the first node can perform subsequent operations based on the fifth message, thereby ensuring the reliability of the first type of data transmission.

[0193] At the same time, one of the first node and the target node is the transmission starting point of the first type of data, and the other of the first node and the target node is the transmission end point of the first type of data, which ensures that the first type of data is only transmitted and processed between the first node and the target node. That is, the first type of data does not need to be further uploaded to the cloud and is processed by the cloud, which avoids the occupation of network bandwidth and resources when the first type of data is uploaded to the cloud, and avoids the problem of long interaction delay caused by round-trip transmission when processing the first type of data, thereby reducing the overhead in the transmission and processing of the first type of data.
