Although the following description describes a New Radio (NR) system for illustrative purposes and uses NR terminology in much of the following description, these techniques may also be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

[0021] Hereinafter, with reference to the drawings, the transmission processing method, device, access network node and core network node provided in the embodiments of the present invention will be described in detail in several embodiments and their application scenarios.

[0022] As shown in Figure 1, an embodiment of the present application provides a transmission processing method, which includes the following steps 101 and 102:

[0023] In step 101, the access network node obtains first information.

[0024] The first information is for indicating a type and / or characteristic of traffic data.

[0025] In step 102, a transmission process of traffic data is performed based on the first information.

[0026] It should be noted that the first information allows the access network node to clearly know which Quality of Service (QoS) flow the traffic data corresponds to, and then, based on this information, performs transmission processing of the traffic data, thereby realizing adaptive transmission of the traffic data.

[0027] It should be noted here that the traffic data mainly refers to packets and / or data frames, and mainly refers to XR traffic data transmitted when performing XR traffic. Naturally, the embodiments of the present application are not limited to XR traffic, and traffic data transmitted in other types of traffic also fall within the scope of protection of the present application.

[0028] Optionally, the first information mentioned in the embodiments of the present application includes at least one of the following A11, A12, A13, A14, A15, A16, A17, A18, and A19.

[0029] A11 is a Quality of Service Flow Indication (QFI).

[0030] It should be noted that the QFI corresponds to the identifier of the traffic data, the sequence number of the traffic data, the importance of the traffic data, and the like.

[0031] A12 is the traffic data identifier.

[0032] It should be noted that the identifier of the traffic data may be a packet identifier or a data frame identifier.

[0033] For example, I-frames and non-I-frames (it should be noted that video frames are usually coded as I-frames and P-frames (or B-frames), where I-frames are intra-coded frames, which do not refer to other frames for coding and decoding, and P-frames (or B-frames) are inter-coded frames, which refer to other frames, e.g., I-frames, for coding and decoding. The size of P-frames is usually smaller than that of I-frames, and it is generally considered that the size ratio between I-frames and P-frames is about 3:1. The characteristics and QoS requirements, such as bit rate and reliability requirements, of I-frames / P-frames are different, with I-frames being more important and having higher PER requirements, while P-frames have relatively lower QoS requirements) may be marked with 0 and 1, and, alternatively, I-frames may be represented by 0 and non-I-frames by 1, or alternatively, I-frames may be represented by 1 and non-I-frames by 0. For example, foreground data and background data may be labeled 0 and 1, selectively representing foreground data as 0 and background data as 1, or selectively representing foreground data as 1 and background data as 0. For example, Field Of View (FOV) data and non-FOV data may be labeled 0 and 1, selectively representing FOV data as 0 and non-FOV data as 1, or selectively representing FOV data as 1 and non-FOV data as 0. For example, left-eye data and right-eye data may be labeled 0 and 1, selectively representing left-eye data as 0 and right-eye data as 1, or selectively representing left-eye data as 1 and right-eye data as 0. For example, the first frame data and the last frame data may be labeled with 0 and 1, alternatively, the first frame data may be represented by 0 and the last frame data by 1, or alternatively, the first frame data may be represented by 1 and the last frame data may be represented by 0.

[0034] A13 is the sequence number of the traffic data.

[0035] For example, the sequence number of the traffic data includes a packet sequence number and / or a data frame sequence number.

[0036] A14 is the importance level of the traffic data.

[0037] For example, the importance level of the traffic data includes the importance level of a packet and / or the importance level of a data frame.

[0038] A15 is the time delay information of the traffic data.

[0039] For example, the time delay information of the traffic data includes packet time delay information and / or data frame time delay information.

[0040] A16 is time stamp information of the traffic data.

[0041] For example, the timestamp information of the traffic data includes packet timestamp information and / or data frame timestamp information.

[0042] A17 is synchronization information for traffic data.

[0043] For example, the traffic data synchronization information includes packet synchronization information and / or data frame synchronization information.

[0044] A18 is the association relationship between different traffic data.

[0045] It should be noted that the association relationship may be an association relationship between packets, such as whether two packets belong to the same data frame, and the association relationship may be an association relationship between data frames, such as whether two data frames are data frames in the same Group of Pictures (GOP).

[0046] A19 is the user plane General Packet Service Tunneling Protocol (GTP-U) serial number.

[0047] Optionally, one possible implementation of step 102 in the embodiment of the present application is: The purpose is to carry out transmission processing of traffic data based on the wireless transmission policy.

[0048] Here, the wireless transmission policy includes at least one of the following B11, B12, B13, B14, and B15.

[0049] In B11, traffic data with the first priority is transmitted preferentially.

[0050] It should be noted that the first priority may be a high priority or a specific priority that is set in advance.

[0051] For example, in the case of preferentially transmitting high-priority packets, B111, transmitting I frames in preference to non-I frames (P frames or B frames); B112, transmitting foreground data in preference to background data; B113, transmitting FOV data with priority over non-FOV data; B114, transmitting low-resolution data in preference to high-resolution data; B115, transmitting data with an earlier timestamp preferentially over data with a later timestamp.

[0052] In B12, traffic data of the first importance is transmitted with priority.

[0053] It should be noted that the first importance may be high importance or traffic data with a specific pre-set demand.

[0054] For example, when priority is given to transmitting packets of high importance, B121, transmitting I frames in preference to non-I frames (P frames or B frames); B122, transmitting foreground data in preference to background data; B123, transmitting FOV data with priority over non-FOV data; B124, transmitting low-resolution data in preference to high-resolution data; B125, transmitting data with an earlier timestamp in preference to data with a later timestamp.

[0055] In B13, relevant traffic data is transmitted jointly.

[0056] For example, this relevant traffic data may be B131, left eye data or right eye data belonging to the same frame screen; B132, data with the same timestamp or within a certain range; B133, foreground data / background data belonging to the same frame screen, B134, and FOV data / non-FOV data belonging to the same frame screen.

[0057] In B14, the scheduling of the first traffic data is delayed.

[0058] It should be noted that the first traffic data may be traffic data of less importance or lower priority.

[0059] It should be further noted that in this case, the wireless transmission policy further includes scheduling the first traffic data together with third traffic data.

[0060] It should be noted that the third traffic data may be traffic data with high importance or high priority, for example, the first traffic data is non-emergency traffic and the third traffic data is emergency traffic, i.e., the transmission of the non-emergency traffic is delayed and scheduled together with the emergency traffic. The third traffic data may be data related to the first traffic data, for example, the first traffic data is left-eye data and the third traffic data is right-eye data belonging to the same frame as the left-eye data, i.e., the scheduling of the left-eye data is delayed and scheduled together with the associated right-eye data; or the first traffic data is right-eye data and the third traffic data is left-eye data belonging to the same frame as the right-eye data, i.e., the scheduling of the right-eye data is delayed and scheduled together with the associated left-eye data.

[0061] In B15, the second traffic data is discarded.

[0062] It should be noted that the second traffic data may be incomplete data, for example, a non-I frame associated with an already lost II frame, i.e., the scheduling of the non-I frame associated with the already lost II frame is discarded. The second traffic data may be data with low priority or low importance, for example, background data, non-FOV data, i.e., the transmission of some background data or non-FOV data is discarded.

[0063] It should be further noted that for uplink data, the access network node can determine and obtain the first information by itself based on the traffic data sent by the terminal, while for downlink data, the access network node does not need to determine the first information by itself, but only needs to obtain the first information from the core network node, and the specific implementation method may adopt at least one of the following C11, C12, and C13.

[0064] C11 receives the QoS flow sent by the core network node, and the first information is carried in the QoS flow.

[0065] It should be noted that in this case, the core network node needs to first generate first information, then map traffic data based on the first information to obtain a QoS flow, and the core network node needs to add the first information to the QoS flow, and then send the QoS flow to the access network node.

[0066] It should be mentioned here that the first information directly generated by the core network node usually includes at least one of the above-mentioned A12 to A19, and after mapping the traffic data according to the directly generated first information to obtain a QoS flow, the core network node obtains a QFI corresponding to the QoS flow, that is, in this case, the core network node maps according to the directly generated first information to obtain a QoS flow, and further obtains first information (in this case, the first information refers to the above-mentioned A11) to send to the access network node, and notifies the access network node of A11 via the QoS flow.

[0067] It should be further noted that the main implementation manner in which the core network node maps traffic data and obtains QoS flows based on the first information is to map traffic data to QoS flows according to pre-set mapping rules.

[0068] The preset mapping rule includes mapping first priority traffic data to a target QoS flow.

[0069] The target QoS flow is a first QoS flow, or the target QoS flow is a QoS flow corresponding to a first QFI.

[0070] It should be noted that the first priority traffic data may be high priority traffic data, the first QoS flow may be a QoS flow with a preset high priority, and the first QFI QoS flow may be a QoS flow with a small / low QFI value, that is, the preset mapping rule is to map the high priority traffic data to a QoS flow with a high priority or a QoS flow with a small / low QFI value.

[0071] For example, I frames are mapped to a first QoS flow and non-I frames are mapped to a second QoS flow, or I frames are mapped to a QoS flow with QFI=1 and non-I frames are mapped to a QoS flow with QFI=2.

[0072] For example, the FoV data is mapped to a first QoS flow and the non-FoV data is mapped to a second QoS flow, or the FoV data is mapped to a QoS flow with QFI=1 and the non-FoV data is mapped to a QoS flow with QFI=2.

[0073] For example, a video frame is divided into multiple QoS flows based on the angle with the visual axis center, and a smaller angle has a higher priority and is mapped to the first QoS flow or a QoS flow with QFI=1, while a smaller angle has a lower priority.

[0074] C12 receives a GTP-U message sent by a core network node, and the first information is carried in the header of the GTP-U message.

[0075] It should be noted that in this case, the core network node needs to first generate first information, insert the first information into the header of the GTP-U message, and then send the GTP-U message to the access network node, and the access network node receives the GTP-U message and analyzes the first information in the header of the GTP-U message (the first information usually includes at least one of A12 to A19 above), thereby being able to know the type and / or characteristics of the traffic data of the QoS flow corresponding to the GTP-U message, and map the QoS flow to the corresponding bearer.

[0076] At C13, the core network node receives first information sent by a Core Access and Mobility Management Function (AMF).

[0077] It should be noted that in this case, the core network node first needs to generate the first information and then send the first information directly to the access network node, and the sending of the first information is realized by AMF.

[0078] It should be noted here that in this case, the first information mainly refers to at least one of A12 to A19 mentioned above. For example, after receiving the serial number of the GTP-U, the access network node maps the QoS flow corresponding to the GTP-U to the corresponding radio bearer.

[0079] It should be further explained that the main implementation process of the core network node generating the first information referred to in the embodiments of the present application is as follows: The information in the second protocol header of the traffic data is analyzed to generate the first information.

[0080] wherein the second protocol header is D11, Slice header, D12, a Network Abstract Layer (NAL) header; D13, a Real-time Transport Protocol (RTP) header, D14, a User Datagram Protocol (UDP) header; D15, a Transmission Control Protocol (TCP) header, D16, and an Internet Protocol (IP) header.

[0081] Optionally, it is further to be explained that before performing the transmission processing of the traffic data according to the first information, the access network node needs to first perform traffic data mapping, and the specific implementation process is as follows: It is to map QoS flows of traffic data to radio bearers according to pre-defined rules.

[0082] For example, the radio bearer here may be a Data Radio Bearer (DRB), that is, the access network node first maps the QoS flow corresponding to the traffic data to the DRB before performing transmission processing.

[0083] Specifically, the preset rules include at least one of the following E11, E12, and E13:

[0084] E11 maps QoS flows with different demands to different radio bearers based on the first information, where the radio bearers have one-to-one correspondence with Radio Link Control (RLC) entities.

[0085] It should be noted that in this case, one set of transmission paths corresponds to one radio bearer, and one set of transmission paths is a transmission path consisting of a Protocol Data Unit (PDU) session, a Service Data Adaptation Protocol (SDAP), a Packet Data Convergence Protocol (PDCP), a Radio Link Control (RLC), and a Medium Access Control (MAC).

[0086] For example, one set of transmission paths corresponds to one DRB, and QoS flows with different demands are mapped to different DRBs based on the first information, and different DRBs correspond to respective RLC entities, and the access network node realizes different radio transmission policies for different transmission paths.

[0087] Taking I frames and non-I frames as examples, I frames are mapped to QoS flow1, non-I frames are mapped to QoS flow2, QoS flow1 is mapped to the transmission path where DRB1 is located, and QoS flow2 is mapped to the transmission path where DRB2 is located, and the base station prioritizes scheduling of data on the transmission path where DRB1 is located.

[0088] Application situation 1, The core network node identifies I frames and non-I frames through deep analysis of the application packets, and maps I frames to QoS flow1 and non-I frames to QoS flow2. It maps QoS flow1 to the transmission path where DRB1 is located, i.e., the transmission path consisting of a PDU session, SDAP, PDCP1, RLC1, and MAC, and maps QoS flow2 to the transmission path where DRB2 is located, i.e., the transmission path consisting of a PDU session, SDAP, PDCP2, RLC2, and MAC. The specific mapping situation can be seen in Figure 2.

[0089] It should be noted that the above-mentioned rules of mapping high priority data (e.g., I-frames) to QoS flow1, mapping low priority data (e.g., non-I-frames) to QoS flow2, mapping QoS flow1 to the transmission path where DRB1 is located, and mapping QoS flow2 to the transmission path where DRB2 is located are predefined and known to the access network node, and the access network node will prioritize scheduling of data on the transmission path where DRB1 is located.

[0090] E12 maps QoS flows with different demands to the same radio bearer, and maps traffic data with different QoS demands to different RLC entities based on the first information, where one radio bearer corresponds to multiple RLC entities.

[0091] It should be noted that in this case, at least two sets of transmission paths correspond to one radio bearer.

[0092] For example, multiple sets of transmission paths correspond to one DRB, and QoS flows with different demands are mapped to the same DRB, and the same DRB corresponds to different RLC entities, and data with different QoS demands are mapped to different RLC entities based on the first information, and the access network node realizes different wireless transmission policies for different transmission paths.

[0093] Taking I frames and non-I frames as an example, I frames are mapped to QoS flow1, and non-I frames are mapped to QoS flow2. QoS flow1 and QoS flow2 are mapped to the same DRB, and data is allocated to different RLC entities based on information such as QFI / priority / importance. I frame data is allocated to RLC1, and non-I frame data is allocated to RLC2. The base station prioritizes scheduling of data on the transmission path where RLC1 is located.

[0094] Application situation 2, The core network node identifies I frames and non-I frames through deep analysis of the application packets, maps I frames to QoS flow1, maps non-I frames to QoS flow2, and maps QoS flow1 and QoS flow2 to the same DRB. The access network node analyzes the first information carried in the GTP-U protocol header to allocate I frame data to RLC1 and non-I frame data to RLC2. The specific mapping situation can be seen in Figure 3, which includes a transmission path consisting of a PDU session, SDAP, PDCP, RLC1, and MAC, and a transmission path consisting of a PDU session, SDAP, PDCP, RLC2, and MAC.

[0095] It should be noted that the above rule of allocating high priority data (e.g., I-frames) to RLC1 and low priority data (e.g., non-I-frames) to RLC2 is predefined and known to the access network nodes, which prioritize scheduling of data on the transmission path where RLC1 is located.

[0096] E13 maps QoS flows with different demands onto the same radio bearer, and sets different transmission configurations for traffic data with different QoS demands based on the first information.

[0097] That is, in this case, QoS flows with different demands are mapped to the same DRB, one DRB corresponds to one RLC entity, and different transmission configurations (mainly time-frequency resources, periods, etc.) are set for data with different QoS demands based on the first information.

[0098] Taking I-frames and non-I-frames as examples, transmission configuration 1 (config1) is set for I-frame data, and transmission configuration 2 (config2) is set for non-I-frame data. The MAC layer determines which configuration to execute for the received data based on information such as QFI / priority / importance.

[0099] Application situation 3, config1 is set in advance to high priority data (for example, I frames), and config2 is set to low priority data (for example, non-I frames). See FIG. 4 for a specific mapping situation.

[0100] The access network node determines whether to execute config1 or config2 on the received data by analyzing the first information carried in the GTP-U protocol header or the information from the received AMF.

[0101] It should be noted that the embodiments of the present application can distinguish different traffic flows by obtaining first information indicating the type and / or characteristics of traffic data, and then perform transmission processing of the traffic data based on the first information, thereby realizing adaptive transmission of traffic and improving the transmission efficiency and reliability of traffic data.

[0102] It should be noted that the execution entity of the transmission processing method provided in the embodiment of the present application may be a transmission processing device or a control module for executing the transmission processing method within the transmission processing device. In the embodiment of the present application, the transmission processing device provided in the embodiment of the present application will be described by taking the transmission processing method as an example.

[0103] 5, an embodiment of the present application provides a transmission processing device 500. The transmission processing device 500 includes an acquisition module 501 and a processing module 502.

[0104] The acquiring module 501 is used for acquiring first information, the first information being for indicating the type and / or characteristics of traffic data.

[0105] The processing module 502 is used for performing transmission processing of traffic data based on the first information.

[0109] Optionally, when the wireless transmission policy includes delaying scheduling of first traffic data, the wireless transmission policy further includes scheduling the first traffic data together with third traffic data.

[0110] Optionally, before the processing module 502 performs a transmission process of traffic data based on the first information, the device: further comprising a mapping module for mapping Quality of Service (QoS) flows of traffic data to radio bearers according to a preset rule; Here, the predetermined rule is: Mapping QoS flows with different demands to different radio bearers based on the first information, where the radio bearers have a one-to-one correspondence with radio link control (RLC) entities; Mapping QoS flows with different requirements to the same radio bearer, and mapping traffic data with different QoS requirements to different RLC entities according to the first information, where one radio bearer corresponds to multiple RLC entities; mapping QoS flows with different requirements to the same radio bearer; and setting different transmission configurations for traffic data with different QoS requirements based on the first information.

[0111] Optionally, the acquisition module 501: receiving a QoS flow transmitted by a core network node, the QoS flow carrying the first information; receiving a GTP-U message sent by a core network node, wherein the first information is carried in a header of the GTP-U message; and receiving first information sent by a core network node via a core access and mobility management function (AMF).

[0112] It should be noted that by obtaining first information indicating the type and / or characteristics of traffic data, different traffic flows can be identified, and transmission processing of the traffic data is performed based on the first information, thereby realizing adaptive transmission of traffic and improving the efficiency and reliability of transmission of traffic data.
