[0052] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0053] 1. Positioning QoS

[0054] Current positioning includes key performance indicators (KPIs) corresponding to different positioning service levels. Among them, positioning accuracy is used to represent the distribution of positioning service performance errors. It is defined by the confidence level and the positioning error threshold. That is, the percentage of the distance between the positioning result and the actual location is within the positioning error threshold. For example, a positioning accuracy of <3m and a confidence level of 95% means that 95% of all calculated positioning results are less than 3 meters away from the actual location. However, the distance between the other 5% of positioning results and the actual location is unknown or cannot be guaranteed.

[0055] Positioning QoS is included in the positioning request, which includes the positioning request required by the positioning requester and the positioning request sent by the LMF to the base station or user equipment (UE). The positioning request sent by the Location Management Function (LMF) to the base station or UE is generated based on the positioning request from the positioning requester.

[0056] A positioning request from a positioning demander, such as a positioning request from a Location Service (LCS) client or an Application Function (AF), may optionally include the following parameter indicators:

[0057] QoS type / level (LCS QoS Class);

[0058] Positioning accuracy (Accuracy), including horizontal positioning accuracy or vertical positioning accuracy;

[0059] The response time type is used to indicate that LMF needs to balance positioning accuracy and response time.

[0060] The QoS levels mentioned above include the following three:

[0061] Best Effort: The most relaxed positioning QoS type. If the positioning result cannot meet other QoS requirements, the positioning result must still be fed back, but it must indicate that the requested QoS was not met. If no positioning result is obtained, the failure reason is fed back.

[0062] Multiple QoS: This is a moderately strict positioning QoS type, which includes QoS requirements corresponding to multiple QoS levels. If the positioning result does not meet the most stringent QoS requirement, the LMF will initiate the positioning process again, trying to meet the lower QoS requirements until one of the QoS requirements is met. If the most relaxed QoS requirement is still not met, the positioning result will not be fed back, and only the failure reason will be fed back.

[0063] Assured: The most stringent positioning QoS type. If the positioning result does not meet other QoS requirements, only the failure reason will be fed back without feedback.

[0064] The response time types include the following three:

[0065] No delay: The LMF shall immediately feedback the initial position of the target UE or the most recent positioning result. If there is no positioning result, a failure message shall be fed back and the positioning process may be triggered to respond to subsequent positioning requests.

[0066] Low latency: Prioritize response time over accuracy. The LCS server should return the current location with minimal latency.

[0067] Latency insensitivity: Prioritizes accuracy over response time. LMF can delay feedback of positioning results until the required positioning accuracy is met.

[0068] The LMF positioning request may optionally include the following parameters:

[0069] Horizontal Accuracy, including positioning accuracy and confidence level;

[0070] Vertical positioning accuracy (VerticalAccuracy), including positioning accuracy and confidence level;

[0071] Response time (ResponseTime) refers to the delay from when the UE receives a positioning information request to when it sends positioning information (including estimated position information or measurement information).

[0072] 5G QoS

[0073] LTE utilizes a bearer-based QoS strategy. Radio bearers are divided into signaling radio bearers (SRBs) and data radio bearers (DRBs). SRBs are used for signaling transmission, while DRBs are used for data transmission. All SRBs have a higher scheduling priority than all DRBs. The QoS Class Identifier (QCI) is a parameter used by the system to identify the transmission characteristics of service data packets. Related technologies define QCI values ​​corresponding to different bearer services. Based on the QCI, bearers can be divided into two categories: guaranteed bit rate (GBR) bearers and non-GBR bearers. GBR bearers are used for services with high real-time requirements. The scheduler must guarantee a minimum bit rate for these bearers, and their QCI range is 1-4. In addition to this minimum rate, a maximum rate is also required. For GBR bearers, the maximum bit rate is limited by the maximum bit rate (MBR). MBR defines the upper limit of the rate that a GBR bearer can reach when RB resources are sufficient. The value of MBR is greater than or equal to the value of GBR. Non-GBR bearers are used for services that do not require high real-time performance. The scheduler does not need to guarantee a minimum bit rate for this type of bearer. Its QCI range is 5-9. In the case of network congestion, services need to withstand the requirement of reducing the rate. For Non-GBR, the UE Aggregate Maximum Bit Rate (AMBR) is used to limit the maximum rate of all Non-GBR bearers.

[0074] 5G QoS Characteristics are the characteristic parameter sets used by each network node (e.g., UE, gNB, UPF) when processing each QoS flow. 5G characteristic parameter sets are divided into standardized QoS characteristics and operator-specific QoS characteristics. In the former, the values ​​of each QoS parameter are pre-defined by the protocol and associated with the fixed 5G QoS Identifier (5QI) value. In the latter, the QoS parameter values ​​are configured by the operator. 5G uses an in-band QoS marking mechanism for data streams. Based on the QoS requirements of the service, the gateway or application server (APP Server) marks the data stream with the corresponding QoS processing label. The network side performs data packet forwarding based on the QoS label. The QoS label can change in real time based on the requirements of the service data flow to meet service needs in real time. The gateway's (GW) non-access stratum (NAS) maps multiple Internet Protocol (IP) flows with the same QoS requirements to a single QoS flow. The gNB maps QoS flows to DRBs, enabling the radio side to adapt to QoS requirements. The RAN has some flexibility, such as the gNB being able to convert QoS flows into DRBs. Downlink mapping is a network implementation; uplink mapping is based on reflective QoS or radio resource control (RRC) configuration. The 5G QoS model supports both guaranteed bit rate (GBR) QoS flows and non-GBR QoS flows, using AMBR to clamp the non-GBR total bandwidth. The 5G QoS model also supports reflective QoS.

[0075] For 5G QoS, the mapping between 5QI and QoS parameter set can be defined by the protocol, or 5QI can be customized based on the QoS parameter set. The above QoS parameters can include at least one of the following:

[0076] Response type (Resource type);

[0077] Priority Level;

[0078] Packet Delay Budget;

[0079] Packet Error Rate (PER);

[0080] Averaging window;

[0081] Maximum Data Burst Volume.

[0082] In addition, QoS flow can be controlled by the SMF entity and established or reconfigured through the PDU session establishment process and modification process. The 5G core network uses parameter set QoS configuration (QoS profile), QoS rules (QoS rule) and uplink / downlink packet detection rule (Packet Detection Rule, PDR) to implement QoS control and guarantee at different network nodes. Among them:

[0083] QoS profile: The SMF is configured to the base station via the AMF using the N2 interface to implement QoS control on the base station side;

[0084] QoS rule and its associated QoS flow level QoS parameters: configured by the SMF to the UE via the AMF using the N1 interface, or the UE can use reflective QoS to implement UE-side QoS control;

[0085] Uplink / downlink PDR: The packet detection rule is provided by the SMF to the UPF, and QoS control is implemented at the UPF node.

[0086] The meanings of the above QoS profile and QoS rule can be found in related technologies and will not be elaborated here.

[0087] The following describes in detail the transmission configuration method and the transmission method provided in the embodiments of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0088] Please refer to FIG. 2 , which is a flowchart of a transmission configuration method provided in an embodiment of the present application. The method may be performed by a first node, as shown in FIG. 2 , and includes the following steps:

[0089] Step 201: A first node receives a first message from a second node, wherein the first message includes a first QoS parameter, and the first QoS parameter is used to transmit data of a data service.

[0090] In this embodiment, the first node may be a node responsible for transmission control. Exemplarily, the first node may include but is not limited to a core network node (e.g., SMF) or an access network node (e.g., a base station, a centralized unit (CU), a centralized unit control plane (CU-Control Plane, CU-CP), etc.).

[0091] The second node may include, but is not limited to, a core network node (e.g., a Data Collection Coordination Function (DCCF)) or an access network node. Exemplarily, the first node may be used for one or more of data quality management or data service quality management, data collection coordination, data transmission configuration, data reporting configuration, and data processing configuration. Data quality management refers to the first node determining QoS-related parameter configuration based on received QoS parameters, thereby achieving QoS control, monitoring, and assurance at different nodes. Data collection coordination refers to the first node determining whether the required data is available based on at least one of the received data request and data subscription information, determining a data provision function that can provide the required data, and sending a data collection configuration. Data reporting configuration refers to configuring the data packet encapsulation of the data provided by the data provision function, including the packet length, packet length distribution characteristics, packet time interval, packet transmission time interval distribution characteristics, whether the data provision function encrypts the data, whether the data provision function scrambles the data, and if encrypted or scrambled, the configuration of the key and scrambling sequence. Data transmission configuration refers to establishing, modifying, and releasing data transmission channels and data transmission QoS management. The above-mentioned data processing configuration refers to the data processing configuration of data transmission nodes, data receiving nodes and other functional nodes other than data transmission nodes and data receiving nodes, including data preprocessing (such as filtering, desensitization), data analysis, etc.

[0092] It is understood that, when both the first node and the second node are core network nodes, they may be different core network nodes, for example, the first node is an SMF and the second node is a DCCF. Similarly, when both the first node and the second node are access network nodes, they may be different access network nodes.

[0093] The first QoS parameters are used for data transmission of data services. Exemplarily, the QoS parameters for user data transmission in a communication service can be reused for data transmission of the data service. In this case, the first QoS parameters can include at least one of a QoS identifier, a resource type, a priority level, a packet delay budget, a packet error rate, an averaging window, and a maximum data burst volume. Alternatively, the QoS parameters for data transmission of the data service can be defined based on the characteristics of the data service.

[0094] In some optional embodiments, the first message includes a data transmission configuration, and the first QoS parameter may be located in the data transmission configuration, wherein the data transmission configuration may be used to establish, modify, release a data transmission channel and data transmission QoS management, etc.

[0095] Step 202: The first node sends a target QoS parameter to a third node, wherein the target QoS parameter is used by the third node to transmit data of the data service, and the target QoS parameter is related to the first QoS parameter, and the third node includes at least one of the following: a data providing node of the data service, and at least one node between the data providing node and the data receiving node of the data service for data transmission or forwarding of the data service.

[0096] For example, in the case where the above-mentioned first QoS parameter is the QoS parameter for user data transmission in the communication service, if the above-mentioned third node is a UE, the above-mentioned target QoS parameter may include a QoS rule (Rule) associated with the above-mentioned first QoS parameter; if the above-mentioned third node is an access network device, the above-mentioned target QoS parameter may include a QoS configuration (QoS profile), which may include the above-mentioned first QoS parameter; if the above-mentioned third node is a UPF, the above-mentioned target QoS parameter may include a data packet detection rule associated with the above-mentioned first QoS parameter, etc.

[0097] For another example, in the case where the above-mentioned first QoS parameter is a QoS parameter for data transmission defined for a data service-oriented feature, if the above-mentioned third node is a data providing node and a terminal, the above-mentioned target QoS parameter may include a data collection identifier and a wireless bearer identifier associated with the first QoS parameter; if the above-mentioned third node is a data providing node and an access network node, the above-mentioned target QoS parameter may include a data collection identifier, a data transmission bearer identifier and the above-mentioned first QoS parameter; if the above-mentioned third node is a data providing node and a core network node, the above-mentioned target QoS parameter may include a data collection identifier and a data transmission bearer identifier associated with the first QoS parameter.

[0098] It can be understood that, when the third node receives the target QoS parameters sent by the first node, it can perform data transmission for data services based on the target QoS parameters. For example, if the above-mentioned target QoS parameters include a data collection identifier and a wireless bearer identifier associated with the first QoS parameters, the third node can classify and mark the collected data based on the data collection identifier and the wireless bearer identifier, and associate it with the corresponding wireless bearer (i.e., the wireless bearer identified by the above-mentioned wireless bearer identifier) ​​for transmission; if the above-mentioned target QoS parameters can include a data collection identifier, a data transmission bearer identifier and the above-mentioned first QoS parameters, the third node can perform transmission control or forwarding according to the first QoS parameters based on the data transmission bearer identifier.

[0099] The transmission configuration method provided by an embodiment of the present application is as follows: a first node receives a first message from a second node, wherein the first message includes a first QoS parameter, and the first QoS parameter is used to transmit data of a data service; and sends a target QoS parameter to a third node, wherein the target QoS parameter is used for the third node to transmit data of the data service, and the target QoS parameter is related to the first QoS parameter, and the third node includes at least one of the following: a data providing node of the data service, and at least one node between the data providing node and the data receiving node of the data service for data transmission or forwarding of the data service, that is, in an embodiment of the present application, the first node configures transmission QoS parameters for the first node (that is, the data providing node and at least one of the nodes between the data providing node and the data receiving node for data transmission or forwarding of the data service) based on the received first QoS parameter, so that the third node can transmit the data of the data service based on the configured QoS parameter, which is conducive to improving the transmission quality of the data of the data service.

[0100] Optionally, one of the data providing node and the data receiving node is a terminal, and the other is a core network node, and the first QoS parameter includes at least one of the following:

[0101] a first QoS identifier;

[0102] Resource type;

[0103] First priority level;

[0104] First packet delay budget;

[0105] First packet error rate.

[0106] The first QoS identifier may be used to indicate a standardized or pre-configured QoS characteristic, such as 5QI or a QoS Class Identifier (QCI).

[0107] The above resource types include non-guaranteed bit rate (Non-GBR) type, GBR type and delay-critical GBR type.

[0108] The first priority level can be used to determine the resource scheduling priority of the QoS flow. This parameter is used to distinguish the QoS flows of a UE and also to distinguish the QoS flows of different UEs. It should be noted that the smaller the value of the first priority level, the higher the priority.

[0109] The first packet delay budget (PDB) defines the upper limit of the tolerable delay when the data packet is transmitted between the UE and the UPF.

[0110] The first Packet Error Rate (PER) defines the upper limit of the ratio of data packets that have been processed by the link layer (e.g., radio link control (RLC)) of the transmitter but have not been submitted to the upper layer (e.g., Packet Data Convergence Protocol (PDCP)) by the corresponding receiver. The purpose of PER is to enable the network to configure appropriate link layer parameters, such as RLC and Hybrid Automatic Repeat reQuest (HARQ) configuration.

[0111] Optionally, when the resource type is a guaranteed bit rate (GBR) type, the first QoS parameter further includes at least one of the following:

[0112] Latency critical indication;

[0113] Averaging window;

[0114] Maximum data burst size.

[0115] The delay critical indication is used to indicate whether it is a delay-critical GBR flow or a non-delay-critical GBR flow.

[0116] The above-mentioned averaging window is used by relevant network elements to calculate the guaranteed flow bit rate (GFBR) and the maximum flow bit rate (MFBR) in the case of GBR or delay-critical GBR.

[0117] For the above-mentioned Maximum Data Burst Volume (MDVB), each GBR Qos flow with a delay-critical resource type should be associated with an MDBV, which represents the maximum amount of data that the 5G-AN needs to serve during one 5G-AN PDB period.

[0118] This embodiment performs data transmission of the data service by multiplexing the QoS parameters of the user data transmission in the communication service, which can simplify the design of the transmission QoS parameters of the data service and is relatively simple to implement.

[0119] Optionally, the first QoS parameter includes at least one of the following:

[0120] a second QoS identifier, the second QoS identifier being used to identify at least one of a second packet delay budget, a transmission resource type, a second priority level, a second packet error rate, a notification control indicator, and a maximum packet loss rate;

[0121] A second packet delay budget is used to indicate an upper limit of a transmission delay of a data packet between a data providing node and a data receiving node;

[0122] Transmission resource type, including delay-sensitive and non-delay-sensitive transmission resource types;

[0123] a second priority level, used to indicate a priority for resource scheduling of the data flow of the data service;

[0124] Second packet error rate;

[0125] Notification control indication, used to indicate whether to request a notification message from the transport control node for a delay-critical data flow if the delay cannot be met, the notification message being used to indicate that the delay cannot be met;

[0126] The maximum packet loss rate is used to indicate the upper limit of the packet loss rate transmitted between the data providing node and the data receiving node.

[0127] In this embodiment, the second QoS identifier is used to identify at least one of a second packet delay budget, a transmission resource type, a second priority level, a second packet error rate, a notification control indicator, and a maximum packet loss rate. In some optional embodiments, the second QoS identifier and the QoS parameters for data transmission for the data service identified by it may be predefined by a protocol, or the second QoS identifier and the QoS parameters for data transmission for the data service identified by it may be customized by an operator.

[0128] It should be noted that the identifier used to identify at least one QoS parameter for data transmission for a data service in this embodiment is not limited to being called a second QoS identifier, and may also be called a data quality identifier (DQI). Furthermore, the specific meanings of the second packet delay budget, transmission resource type, second priority level, second packet error rate, notification control indicator, and maximum packet loss rate identified by the second QoS identifier can be found in the following related description.

[0129] The second packet delay budget is used to indicate the upper limit of the tolerable delay when the data packet is transmitted between the data providing node and the data receiving node.

[0130] For the above transmission resource types, considering that the data of data services is generated and transmitted by the mobile network, characteristics such as the average window and maximum data burst size are all controlled by the mobile network. Therefore, the bit rate can be controlled by the mobile network based on a variety of factors. Therefore, the transmission resource types corresponding to data services can be divided into two types: delay-sensitive and non-delay-sensitive.

[0131] The second priority level is used to determine the resource scheduling priority of the data flow of the data service. Exemplarily, the second priority level can be used to distinguish between data transmission flows of a single UE, or data transmission flows of different UEs. A data transmission flow can be a data collection task, which can include the collection of one or more data items, or a group of data collection tasks.

[0132] The second packet error rate, i.e., the upper limit of the ratio of data packets processed by the transmitter but not submitted to the upper layer by the corresponding receiver, is used to allow the network to configure appropriate link layer parameters, such as RLC and HARQ configurations.

[0133] The notification control indication is used to indicate, for a delay-critical data flow, whether to request a notification message from the transmission control node if the delay cannot be met, the notification message being used to indicate that the delay cannot be met. The transmission control node may include a RAN, a UE, or a CN, etc. For example, if the notification control indication indicates that, for a delay-critical data flow, a notification message is requested from the transmission control node if the delay cannot be met, then, for the delay-critical data flow, upon determining that the delay cannot be met, the transmission control node sends a notification message to the corresponding node to indicate that the delay cannot be met. If the notification control indication indicates that, for a delay-critical data flow, a notification message is not requested from the transmission control node if the delay cannot be met, then, for the delay-critical data flow, upon determining that the delay cannot be met, the transmission control node does not send a notification message to the corresponding node to indicate that the delay cannot be met.

[0134] The maximum packet loss rate above represents the maximum tolerable packet loss rate for transmission between a data-providing node and a data-receiving node. For large amounts of data, the loss of a single independent data packet from a single data-providing node does not significantly impact the overall integrity of the data, as long as the overall data integrity of all data-providing functions meets the required integrity.

[0135] This embodiment defines QoS parameters for data transmission of data services based on the characteristics of the data services, which can ensure that the determined transmission QoS parameters can better fit the data transmission characteristics of the data services, thereby helping to improve the accuracy of data transmission control of the data services.

[0136] Optionally, the second priority level comprises at least one of a priority indication and a priority value of a data flow of the data service;

[0137] The priority indication is used to indicate one of the following:

[0138] The data flow of data service has a higher priority than the data flow of user data;

[0139] The priority of the data flow of data service is lower than the priority of the data flow of user data;

[0140] The user data is data transmitted by the user plane (UP).

[0141] In one embodiment, the priority relationship between the data flow of the data service and the data flow of the user data is determined based on the priority indication. For example, if the priority indication indicates that the priority of the data flow of the data service is higher than the priority of the data flow of the user data, then the data flow of the data service will be scheduled for transmission in priority in addition to the control plane signaling during resource scheduling; if the priority indication indicates that the priority of the data flow of the data service is lower than the priority of the data flow of the user data, then the data flow of the user data will be scheduled for transmission in priority during resource scheduling, and the data flow of the data service will be scheduled for transmission only when there is no data flow of user data.

[0142] In another embodiment, a priority relationship between a data service data flow and a user data data flow is determined based on a priority indication, and a priority relationship between the data service data flows is determined based on the priority values ​​of the data service data flows. For example, if the priority indication indicates that the data service data flow has a higher priority than the user data data flow, the data service data flow will be prioritized for transmission during resource scheduling, in addition to control plane signaling. For multiple data service data flows, transmission scheduling can be performed based on the priority values ​​of each data flow. An optional priority determination method is to schedule data flows with lower priority values ​​earlier.

[0143] In another embodiment, scheduling can be performed based on the priority values ​​of the data flows of each data service and the priority values ​​of the data flows of each user data. In other words, when scheduling resources, scheduling is performed based on the priority values ​​of all data flows to be scheduled. In this case, an optional priority determination method is to schedule data flows with lower priority values ​​earlier.

[0144] Optionally, when the second priority level is the priority value of the data flow of the data service, the priority value of the data flow of the data service is determined according to the priority level in the second QoS parameter; wherein the second QoS parameter is used to transmit user data of the communication service.

[0145] In this embodiment, when resource scheduling of various types of data flows is performed only based on the priority values ​​of the data flows, the priority values ​​of the data flows of the data service can be determined with reference to the numerical values ​​of the priority levels in the QoS parameters used to transmit user data. For example, the value range of the priority values ​​of the data flows of the data service can be set to be the same as the value range of the priority levels in the above-mentioned QoS parameters used to transmit user data. This ensures that the distribution range of the priority values ​​of the data flows of the data service and the priority values ​​of the data flows of the user data are the same, which is conducive to achieving flexible scheduling of the data flows of the data service and the data flows of the user data.

[0146] Optionally, the target delay budget is less than or equal to a first duration, where the first duration is T-T1-PQ, where T is a total delay from when the second node receives a data request to when it sends data, T1 is a delay from when the data providing node receives a data request to when it sends data, P is a processing time of the second node on the data provided by the data providing node, and Q is a delay from when the second node receives a data request to when the data providing node receives the data request;

[0147] The target delay budget includes a first packet delay budget or a second packet delay budget.

[0148] Exemplarily, as shown in FIG3 , T represents the total delay from the second node receiving the data request to the second node sending the data. For example, T represents the total delay from the second node receiving the second message to the second node sending the data provided by the data providing node to the sending node of the second message or the data receiving node. T1 represents the delay from the data providing node receiving the data request to the data sending node. For example, T1 represents the delay from the data providing node receiving the data request sent by the first node to the data providing node sending the provided data to the first node. P represents the processing time of the data provided by the data providing node by the second node. It should be noted that, in the absence of QoS requirements, the second node directly provides data to the sending node of the second message or the data receiving node, or the second node performs data format conversion or generates new data on the data provided by the data providing node. In the presence of QoS requirements, the second node can directly perform data quality assessment on the data provided by the data providing node, or can pre-process the data provided by the data providing node (for example, removing redundancy, combining data from multiple data providing nodes into a sample required by the external party, etc.), and then perform data quality assessment on the pre-processed data. The Q represents the delay from when the second node receives the data request to when the data providing node receives the data request. For example, the Q represents the delay from when the second node receives the second message to when the data providing node receives the data request sent by the second node. The second message is used to request the data service.

[0149] Optionally, the first node sends a target QoS parameter to the third node, including at least one of the following:

[0150] In a case where the third node includes a terminal, the first node sends a target QoS rule to the terminal, where the target QoS rule includes a target data flow identifier, and the target QoS rule is a QoS rule associated with the first QoS parameter;

[0151] In a case where the third node includes an access network node, the first node sends a QoS configuration to the access network node, where the QoS configuration includes a third QoS parameter and a target data flow identifier, and the third QoS parameter is determined according to the first QoS parameter;

[0152] In a case where the third node includes a user plane function, the first node sends a target data packet detection rule and a target data flow identifier to the user plane function, where the target data packet detection rule is a data packet detection rule associated with the first QoS parameter;

[0153] The target data flow identifier is a data flow identifier associated with the first QoS parameter.

[0154] It can be understood that, when the third node includes a terminal, the above-mentioned target QoS parameters include a target QoS rule (QoS rule) and a target data flow identifier; when the third node includes an access network node, the above-mentioned target QoS parameters include a target QoS configuration (QoS profile); when the third node includes a user plane function, the above-mentioned target QoS parameters include a target data packet detection rule (PDR) and a target data flow identifier.

[0155] The target QoS rule may be a target data flow identifier, for example, a QoS flow identifier (QFI). In some optional embodiments, the target QoS rule may further include, but is not limited to, at least one of an indication indicating whether the QoS rule is a default QoS rule, a QoS rule identifier (QRI), a precedence value, and a packet filter.

[0156] For example, the first node may assign a QoS Rule to the UE via a Non-Access Stratum (NAS) Protocol Data Unit (PDU) Session Establishment Accept message or a PDU Session Modification Command. Furthermore, the data collection identifier and the QFI may be used to instruct the UE to associate the collected data corresponding to the data collection identifier with the corresponding QFI.

[0157] The target QoS configuration includes a third QoS parameter and a target data flow identifier, wherein the third QoS parameter may include, but is not limited to, at least one of the following: a first QoS identifier; a resource type; a first priority level; a third packet delay budget; and a first packet error rate. The third packet delay budget may be determined based on the first packet delay budget. In some optional embodiments, the target QoS configuration may further include at least one of an allocation and retention priority (ARP), GBR QoS flow information (GBR QoS Flow Information), and a reflective QoS attribute (RQA).

[0158] Exemplarily, the first node may transmit the QoS configuration to the access network node (e.g., gNB) through the AMF. For example, the AMF may utilize the N2 interface to transmit the QoS configuration to the access network node through a PDU Session Resource Modify Request message or a PDU Session Resource Setup Request message.

[0159] For the above-mentioned target data packet detection rule, illustratively, the first node may send a message to the UPF via the N4 interface, where the message may include the target data packet detection rule and the QFI. In some optional implementations, the above-mentioned message may also include at least one of the N4 session ID, forwarding action rules (FAR), multi-access rules (MAR), usage reporting rules (URR), QoS enforcement rules (QER), session reporting rules (SRR), trace requirements, port management information container (PMIC), bridge information, etc.

[0160] This embodiment configures transmission QoS for a data providing node and at least one of the nodes used for data transmission or forwarding of the data service between the data providing node and the data receiving node by multiplexing the QoS parameters of user data transmission in the communication service, thereby reducing system complexity.

[0161] Optionally, when the third QoS parameter includes a third packet delay budget, the third packet delay budget is less than or equal to a second duration, the second duration is T2-T3, T2 is the first packet delay budget, and T3 is the transmission delay between the user plane function and the data receiving node.

[0162] Exemplarily, T2 and T3 may be as shown in FIG3 , and the third packet delay budget is less than or equal to T2 − T3 .

[0163] In some optional embodiments, the first message further includes a data collection identifier.

[0164] Optionally, the third node is the data providing node;

[0165] The first node sends a target QoS parameter to the third node, including at least one of the following:

[0166] In a case where the third node includes a terminal, the first node sends a fourth QoS parameter to the terminal, wherein the fourth QoS parameter includes a data collection identifier and a radio bearer identifier, and the fourth QoS parameter is associated with the first QoS parameter;

[0167] In a case where the third node includes an access network node, the first node sends a fifth QoS parameter to the access network node, wherein the fifth QoS parameter includes a data collection identifier, a data transmission bearer identifier, and the first QoS parameter;

[0168] In the case where the third node includes a core network node, the first node sends a sixth QoS parameter to the core network node, wherein the sixth QoS parameter includes a data collection identifier and a data transmission bearer identifier, and the sixth QoS parameter is associated with the first QoS parameter.

[0169] It can be understood that, when the third node includes a terminal, the above-mentioned target QoS parameters include a fourth QoS parameter; when the above-mentioned third node includes an access network node, the above-mentioned target QoS parameters include a fifth QoS parameter; when the above-mentioned third node includes a user plane function, the above-mentioned target QoS parameters include a sixth QoS parameter.

[0170] For the terminal as a data providing node, the fourth QoS parameter sent by the first node to the terminal includes at least a data collection identifier and a radio bearer identifier. The default management granularity of the transmission QoS of the data service is at the radio bearer level, that is, the QoS parameter is associated with a certain radio bearer. In the case where a radio bearer can transmit QoS flows corresponding to multiple data services, finer-grained QoS management is required, for example, QoS flow-level QoS management. In this case, the above-mentioned fourth QoS parameter may also include a QoS flow identifier. Specifically, the terminal classifies and marks the collected data according to the received fourth QoS parameter, and associates it with the corresponding radio bearer or the QoS flow of the radio bearer.

[0171] When the access network node functions as a data providing node, the fifth QoS parameter sent by the first node to the access network node includes a data collection identifier, a data transmission bearer identifier, and the first QoS parameter. Specifically, the access network node classifies and labels the collected data based on the received QoS parameter, associates the collected data with the corresponding data transmission bearer, and performs transmission control based on the first QoS parameter.

[0172] For a core network node serving as a data providing node, the sixth QoS parameter sent by the first node to the core network node includes a data collection identifier and a data transmission bearer identifier. Specifically, the core network node classifies and marks the collected data based on the received sixth QoS parameter and associates it with the corresponding data transmission bearer.

[0173] This embodiment configures transmission QoS parameters for each type of data providing node based on the characteristics of the data service. This not only supports QoS parameter control of data transmission between the terminal and the core network node, but also supports QoS parameters for data transmission between the terminal and the access network node, which can meet the requirements of flexible data termination at the UE, RAN and CN required by the data service.

[0174] Optionally, the third node is a node used for data transmission or forwarding of the data service between the data providing node and the data receiving node;

[0175] The first node sends a target QoS parameter to the third node, including at least one of the following:

[0176] In a case where the third node includes a terminal or a core network node, the first node sends a seventh QoS parameter to the terminal or the core network node, wherein the seventh QoS parameter is associated with the first QoS parameter and includes a data detection rule and a data forwarding rule;

[0177] In a case where the third node includes an access network node, the first node sends a ninth QoS parameter to the access network node, wherein the ninth QoS parameter includes a data detection rule, a data forwarding rule, and the first QoS parameter;

[0178] The data detection rule includes a data providing node identifier and a data receiving node identifier, and the data forwarding rule includes first indication information, and the first indication information is used to instruct to forward, discard or cache the data detected by the data detection rule.

[0179] It can be understood that when the third node includes a terminal or a core network node, the above-mentioned target QoS parameters include the seventh QoS parameter; when the above-mentioned third node includes an access network node, the above-mentioned target QoS parameters include the fifth QoS parameter; when the above-mentioned third node includes a user plane function, the above-mentioned target QoS parameters include the ninth QoS parameter.

[0180] Specifically, the access network node, UE or core network node can identify data flows of different data services according to the data detection rule and perform data forwarding processing according to the data forwarding rule. In addition, the access network node can also control data transmission according to the first QoS parameter.

[0181] Please refer to FIG4 , which is a flowchart of a transmission method provided in an embodiment of the present application. The method may be performed by the second node, as shown in FIG4 , and includes the following steps:

[0182] Step 401: A second node sends a first message to a first node, wherein the first message includes a first quality of service (QoS) parameter, and the first QoS parameter is used to transmit data of a data service.

[0183] Optionally, one of the data providing node of the data service and the data receiving node of the data service is a terminal, and the other is a core network node, and the first QoS parameter includes at least one of the following:

[0184] a first QoS identifier;

[0185] Resource type;

[0186] First priority level;

[0187] First packet delay budget;

[0188] First packet error rate.

[0189] Optionally, when the resource type is a guaranteed bit rate (GBR) type, the first QoS parameter further includes at least one of the following:

[0190] Latency critical indication;

[0191] Averaging window;

[0192] Maximum data burst size.

[0193] Optionally, the first QoS parameter includes at least one of the following:

[0194] a second QoS identifier, the second QoS identifier being used to identify at least one of a second packet delay budget, a transmission resource type, a second priority level, a second packet error rate, a notification control indicator, and a maximum packet loss rate;

[0195] A second packet delay budget is used to indicate an upper limit of a transmission delay of a data packet between a data providing node and a data receiving node;

[0196] Transmission resource type, including delay-sensitive and non-delay-sensitive transmission resource types;

[0197] a second priority level, used to indicate a priority for resource scheduling of the data flow of the data service;

[0198] Second packet error rate;

[0199] Notification control indication, used to indicate whether to request a notification message from the transport control node for a delay-critical data flow if the delay cannot be met, the notification message being used to indicate that the delay cannot be met;

[0200] The maximum packet loss rate is used to indicate the upper limit of the packet loss rate transmitted between the data providing node and the data receiving node.

[0201] Optionally, the second priority level comprises at least one of a priority indication and a priority value of a data flow of the data service;

[0202] The priority indication is used to indicate one of the following:

[0203] The data flow of data service has a higher priority than the data flow of user data;

[0204] The priority of the data flow of data service is lower than the priority of the data flow of user data;

[0205] The user data is data transmitted via the user plane UP.

[0206] Optionally, when the second priority level is the priority value of the data flow of the data service, the priority value of the data flow of the data service is determined according to the priority level in the second QoS parameter; wherein the second QoS parameter is used to transmit user data of the communication service.

[0207] Optionally, the target delay budget is less than or equal to a first duration, where the first duration is T-T1-PQ, where T is a total delay from when the second node receives a data request to when it sends data, T1 is a delay from when the data providing node receives a data request to when it sends data, P is a processing time of the second node on the data provided by the data providing node, and Q is a delay from when the second node receives a data request to when the data providing node receives the data request;

[0208] The target delay budget includes a first packet delay budget or a second packet delay budget.

[0209] Optionally, the method further includes:

[0210] The second node obtains a ninth QoS parameter;

[0211] The ninth QoS parameter includes at least one of the following:

[0212] The lower limit of quantization accuracy;

[0213] The upper limit of the response time, where the response time represents the delay between receiving a data request and sending the data, or the delay between receiving a data request and the sent data reaching the receiving node;

[0214] The lower limit of accuracy is used to indicate the closeness between the data collection value and the true value of the data;

[0215] The lower limit of correctness, where correctness is used to represent the ratio of the number of times the provided data is true to the total number of times the data is provided;

[0216] Valid time, used to indicate the upper limit of the time length between the time point of data collection and the reference time point;

[0217] The lower limit of the completeness, which is used to represent the ratio between the amount of data actually collected and the amount of data that should be collected;

[0218] The upper limit of redundancy, which is used to indicate the proportion of identical or similar data in the collected data;

[0219] The lower limit of consistency is used to indicate the proportion of consistent data in the data provided by the data providing node.

[0220] The lower limit of the quantization precision (Precision) mentioned above can be understood as requiring that the quantization precision of the data provided or collected should not be less than the lower limit of the quantization precision. The quantization precision is related to the range of the quantized value, the quantization method, and the number of bits after quantization. For example, for continuous values ​​in the range of 1 to 10, including 1 and 10, quantized by the uniform quantization method and represented by 8 bits after quantization, the quantization precision is approximately (10-1) / (2 8 - 1)≈0.0353. This shows that, once the object to be collected or observed and the quantization method are determined, the greater the number of bits used in quantization, the higher the quantization accuracy. For example, if the lower limit of the quantization accuracy is 8 bits, then the accuracy of the provided or collected data must be quantized with no fewer than 8 bits.

[0221] The upper limit of the response time can be understood as requiring that the delay between receiving a data request and sending data must not exceed the upper limit of the response time. Alternatively, it can be understood as requiring that the delay between receiving a data request and the sent data reaching the receiving node must not exceed the upper limit of the response time. For example, if the upper limit of the response time is 10ms, it means that the delay between the first node receiving a data request and sending data must not exceed 10ms.

[0222] The lower limit of accuracy can be understood as requiring the accuracy of the collected data to be no less than the lower limit of accuracy. The accuracy is used to indicate the degree of closeness between the collected data value and the true value of the data. Alternatively, the accuracy can be expressed by the error between the collected data value and the true value of the data. The larger the error, the lower the accuracy. For example, at a certain confidence level (e.g., 90%), if the lower limit of accuracy is 90%, then the accuracy of the collected data must be no less than 90%.

[0223] For example, if A represents real data and A′ represents collected data or observed data, then the accuracy Acc can be calculated as follows:

[0224] When the collected or observed data consists of a set of data, for example, A′ of M×N, then the accuracy Acc can be calculated as follows:

[0225] Where Amn′ represents the collected data or observed data in the mth row and nth column, and Amn represents the real data corresponding to Amn′. In some optional embodiments, if the importance of the collected or observed data is different, a weight Wmn can be set according to the importance of the data, where Wmn represents the importance of the data of Amn. In this case, the accuracy Acc can be calculated as follows:

[0226] It should be noted that when a set of data is collected or observed, the accuracy of each collected data or observed data can also be calculated to obtain a set of accuracies, wherein the accuracy of each collected data or observed data can be calculated based on the above formula (1).

[0227] The lower limit of the above-mentioned correctness can be understood as requiring that the correctness of the data provided cannot be less than the lower limit of the above-mentioned correctness. Among them, the above-mentioned correctness can also be called authenticity. The correctness of the data depends on the controllability of the data collection process. The higher the controllability, the better the traceability, the higher the authenticity, and the lower the probability of malicious modification. If N1 represents the total number of times data is provided, and M1 represents the number of times the provided data is real data, then a method for calculating correctness Rig can be as follows: Rig = M1 / N1×100%. For example, if the lower limit of correctness is 95%, it can be said that the correctness of the data provided is required to be no less than 95%.

[0228] The above-mentioned valid time (Valid Time) can be understood as requiring that the time length between the time when data is collected and the reference time point cannot exceed the above-mentioned valid time. The above-mentioned reference time point can be the current time point, the time point when a specified event occurs, or a specified time point, etc. For example, if the valid time is x1 time units and the reference time point is the current time, it can be said that the time when data is collected is within x1 time units from the current time; or, if the valid time is x2 time units and the reference time point is a specified time, it can be said that the time when data is collected is within x2 time units before and after the specified time, or within x2 time units before the specified time, or x2 time units after the specified time, etc.; or, if the valid time is x3 time units and the reference time point is a specified event, it can be said that the time when data is collected is x3 time units after the time when the specified event occurs. Wherein, x1, x2 and x3 are all positive numbers, and the above-mentioned time units can include but are not limited to at least one of hours, minutes, seconds, milliseconds, time slots, subframes, etc.

[0229] The lower limit for integrity can be understood as requiring the integrity of the collected data to be no less than the lower limit. For example, if the lower limit is 80%, it means that the integrity of the collected data must be no less than 80%. The above integrity is measured based on the degree of data collection and is the ratio of the actual amount of data collected to the amount of data that should be collected. It should be noted that the above integrity can be the ratio of the actual amount of data collected to the amount of data that should be collected, or it can be the ratio of the amount of data that should be collected to the actual amount of data collected.

[0230] For example, according to different data collection requirements, it can be divided into two dimensions: one is the time dimension, which is used to characterize the completeness of each collected sample at different sampling time points; the other is the space dimension, which is used to characterize the completeness of a sample at the same sampling time interval or time point. The data to be collected or observed is A' of M×N, where M and N are integers greater than or equal to 1. Amn' is the actual data collected or observed. If Amn' is actually collected, then Bmn=1, otherwise Bmn=0. Then one way to calculate the completeness Int can be as follows:

[0231] This calculation method obtains the completeness of the aforementioned spatial dimension. If the required data is a series of samples at multiple sampling points, then P represents the total number of samples that should be collected, and Q represents the total number of samples actually collected. Then one way to calculate the completeness Int can be as follows: This calculation method obtains the completeness of the aforementioned time dimension.

[0232] If the integrity of both dimensions is considered at the same time, then one way to calculate the integrity Int is as follows:

[0233] For example, the required data for a certain time interval or time point is the uplink Reference Signal Received Power (RSRP), downlink RSRP, uplink and downlink throughput, and uplink and downlink latency of the UE's serving cell. However, due to reasons such as the UE not reporting, only four data items, namely uplink RSRP, uplink throughput, downlink throughput, and uplink latency, are actually collected. Therefore, the completeness is 0.667. For another example, the required data is the uplink RSRP of the UE's serving cell for 100 consecutive subframes. However, due to the UE not scheduling uplink data or reference channels, only uplink RSRP of the UE's serving cell is actually collected for 80 subframes. Therefore, the completeness is 80%.

[0234] The upper limit of the redundancy can be understood as requiring the redundancy of the collected data to not exceed the upper limit. For example, if the upper limit of the redundancy is 1%, it can be understood as requiring the redundancy of the collected data to not exceed 1%. The redundancy is used to indicate the proportion of identical or similar data in the collected data. With T representing the total amount of data and R representing the amount of data after removing duplicate or redundant information, the redundancy Red can be calculated as follows:

[0235] It should be noted that the method of deduplication (also known as de-duplication) of data depends on the specific data service requirements. In some optional embodiments, the above deduplication method may include but is not limited to at least one of the following:

[0236] Deduplication is achieved based on the hash algorithm, that is, hashing the data and treating the data with the same hash value as duplicate data;

[0237] Deduplication is based on a sorting algorithm, which sorts the data and then scans the data to remove duplicate adjacent data or remove duplicate adjacent data that meets the similarity judgment.

[0238] Database-based deduplication uses the database's deduplication function to store data in the database and use deduplication query statements to deduplicate data.

[0239] For the above lower limit of consistency, it can be understood that the proportion of data with consistency in the provided data must not be less than the above lower limit of consistency. For example, if the above lower limit of consistency is 100%, it means that all provided data are required to be consistent. For the judgment of data consistency, for example, if the AMF identifier (for example, AMF Set ID and AMF pointer) contained in the UE short form temporary mobile user identity (Shorted form-Temporary Mobile Subscriber Identity, 5G-S-TMSI) is inconsistent with the AMF identifier in the data set, then the data is inconsistent, otherwise it is consistent. It should be noted that the method of judging data consistency may include but is not limited to judging based on the meaning and value of the data, judging by comparing and analyzing multiple copies of data, etc.

[0240] Exemplarily, upon receiving the above-mentioned fourth QoS parameter, the second node may send the above-mentioned fourth QoS parameter to the data providing node, and then the data providing node may perform data quality assessment on the collected data of the data service based on the above-mentioned fourth QoS parameter, or the second node may send the above-mentioned fourth QoS parameter to the data receiving node, and then the data receiving node may perform data quality assessment on the received data of the data service based on the above-mentioned fourth QoS parameter, which is conducive to improving the quality of the data service.

[0241] Optionally, the completeness includes at least one of the following:

[0242] The first completeness is used to indicate the completeness of the sample, where the completeness of the sample is the ratio between the amount of data actually collected and the amount of data that should be collected in the sample;

[0243] The second completeness is used to indicate the completeness of the sample set, where the completeness of the sample set is the ratio between the number of data actually collected in the sample set and the number of data that should be collected, or the completeness of the sample set is the ratio between the number of samples actually collected in the sample set and the number of samples that should be collected, and the sample set includes at least two samples, and each of the samples should collect at least one data.

[0244] Regarding the completeness of the sample, for example, if the number of data that should be collected for sample A is N2 and the actual number of data collected is M2, then the completeness of sample A can be:

[0245] The completeness of a sample set is the ratio between the number of data actually collected in the sample set and the number of data that should be collected. For example, if the sample set includes sample A1, sample A2, and sample A3, 10 data should be collected for each sample. For sample A1, the actual number of data collected is 9, for sample A2, the actual number of data collected is 8, and for sample A3, the actual number of data collected is 10. Then the completeness of the above sample set can be: (9+8+10) / 30.

[0246] The completeness of a sample set is the ratio between the number of samples actually collected in the sample set and the number of samples that should be collected. For example, if the sample set includes sample A1, sample A2 and sample A3, 10 data should be collected for each sample. For sample A1, the actual number of data collected is 9, for sample A2, the actual number of data collected is 8, and for sample A3, the actual number of data collected is 10. For each sample, the sample must reach 90% completeness before it is regarded as an actually collected sample or a validly collected sample. In this case, since only the completeness of samples A1 and sample A3 reaches 90%, the completeness of the above sample set can be: 2 / 3.

[0247] For example, some AI models have stringent input requirements, perhaps requiring a single sample integrity of 1. Therefore, only samples with an integrity of 1 are valid. In this case, during data cleaning, samples with an Int value less than 1 are deleted. Therefore, if P represents the total number of samples to be collected, and X represents the number of valid samples with an integrity greater than the threshold, then the dataset integrity is calculated as X / P.

[0248] Optionally, the second completeness is the ratio between the number of valid samples actually collected in the sample set and the number of samples that should be collected, and the valid number of samples is the number of samples in the number of samples actually collected whose first completeness is greater than or equal to a preset value.

[0249] In this embodiment, the first completeness of each collected sample can be calculated separately, and samples with a first completeness greater than or equal to a preset value are considered valid samples. The completeness of the sample set is then calculated based on the number of valid samples and the number of samples to be collected. The preset value can be reasonably set according to actual needs, for example, 90%, 100%, etc. In some optional embodiments, the preset value can be a lower limit of the first completeness.

[0250] Optionally, the second node acquiring a ninth QoS parameter includes:

[0251] The second node receives a second message, where the second message includes the ninth QoS parameter, and the second message is used to request the data service;

[0252] or,

[0253] The second node determines the ninth QoS parameter.

[0254] In one embodiment, the second node may receive a second message. For example, the first node may receive a second message from a fourth node. The second message is used to request the data service, and the second message includes the ninth QoS parameter.

[0255] Optionally, in addition to the ninth QoS parameter, the second message may further include at least one of the following: a data target, a data area, and a data name. The data target may also be referred to as a measurement object, and the data name may also be referred to as a data item. For example, for the uplink RSRP of UE A, UE A is the data target, and uplink RSRP is the data name. For another example, for the uplink throughput of a cell within area D, area D is the data area, and uplink throughput is the data name.

[0256] The fourth node may include a network information opening function, a mobility management function, an AF, a UE, a wireless access network node, or a core network function node. It should be noted that when the AF is a trusted AF, the fourth node may be an AF. In addition, when the fourth node is a UE, the UE may directly send the second message to the second node, or the UE may send the second message to the mobility management function, which then selects a suitable second node and sends the second message to the second node. The following examples are provided for different situations:

[0257] Case 1: The fourth node is a network exposure function.

[0258] When the AF outside the network needs data, the AF, which usually serves as a data consumption function, needs to send a data service request message or a data subscription message to the network open function first. For example, the network development function in the 5G protocol determines the second node based on the data service request or the data subscription message, and sends the second message to the second node.

[0259] Case 2: The fourth node mentioned above is a mobility management function.

[0260] The network open function determines the mobility management function based on the data service request or data subscription message, for example, the AMF in the 5G protocol. The mobility management function determines the second node and sends a second message to the second node. It should be noted that when the data service request includes a data target, and the data target is a UE or a base station, and the data target reuses the identifier used by the relevant mobility management function, it is more appropriate for the mobility management function node to select the second node.

[0261] In this embodiment, the ninth QoS parameter is determined by the node requesting the data service, so that the quality of service of the provided data service can be more closely aligned with the needs of the node requesting the data service.

[0262] It is understood that upon receiving the second message, the second node may select at least one data providing node based on at least one of the second message, user permission information, and data capability information of the data providing node, and send a request message to the selected data providing node. The selected data providing node may collect data of the data service based on the request message and provide the data to the second node.

[0263] The data providing node may include at least one of a UE, an access network device, and a core network device.

[0264] The user permission information is used to indicate whether the data providing node is allowed to provide the required data to the data requesting node or the data consumer. Exemplarily, the user permission information may include at least one of the following:

[0265] The authorization type of the data service, including allowing or not allowing the execution of the user-related data service, or asking the user whether to allow it when the user-related data service arrives;

[0266] Data service authorization information or the validity period of the authorization;

[0267] User data classification information: Users define different levels and the data included in different levels according to their personal wishes. For example, they define three levels and the data included in high, medium, and low. High-level data includes data identified by the user's mobile phone number or user permanent identifier (SUPI), instant messaging software data, etc.; medium-level data includes positioning data, perception data, etc.; low-level data includes measurement data identified by a wireless domain ID (for example, cell radio network temporary identity (C-RNTI));

[0268] The data range that the network is allowed to provide data services, for example, represented by one of the above high, medium, low, or any combination of the three;

[0270] Data storage configuration information, namely, the data plane functions that allow data storage, the data that can be stored by different data collection functions, the storage time length or storage space size, whether distributed storage is required, and other security requirements.

[0271] The data capability information is used to indicate whether the data providing node has the capability to provide the required data. The data capability information may include at least one of the following:

[0272] At least one of the supported data targets, data areas, and data names;

[0273] The maximum supported data reporting rate, which can also be called the maximum supported data collection rate or the maximum data plane uplink rate. To avoid the difficulty of representing a large continuous data range, different rate ranges can be defined as different rate levels from the perspective of standard definition. In this case, only the level information needs to be provided for this parameter to improve representation efficiency.

[0274] The maximum supported data reception rate. This parameter item can also be called the maximum supported data usage rate, the maximum supported data distribution rate, or the maximum downlink rate of the data plane. From the perspective of standard definition, different rate ranges can also be defined as different rate levels. In this case, this parameter item only needs to provide the level information to improve the representation efficiency.

[0275] Total buffer size for the data plane. This parameter can be the total buffer size for all protocol layers or the total buffer size for each layer, for example, the total buffer size for Layer 2 or Layer 3.

[0276] Indicates supported data plane functions, indicating that the UE supports any one or more of data reporting, reception, security, pre-processing or data analysis required by the data plane;

[0277] Maximum number of data collection items supported. Because data collection requires corresponding hardware resources and software processing support, this parameter is used to indicate the maximum number of data collection items that can be supported simultaneously (for example, the maximum number of RSRP and Reference Signal Received Quality (RSRQ) data items that can be supported simultaneously). This parameter can be the maximum number of data collection items supported for all data. When data is classified or defined in levels, this parameter can also indicate the maximum number of data collection items supported by the UE for a certain category or level of data.

[0278] Supported sequence number sizes. For example, when configuring data collection, a data collection subscription ID is usually sent to the UE. The length of the ID sequence number can be represented by a number of bits. When the UE needs to use the data provided by the data plane, there is also a corresponding data reception subscription ID.

[0279] The minimum time granularity of data collection supported is used to indicate the minimum time granularity of data that the UE can collect. For example, for RSRP, the minimum time granularity is each Transmission Time Interval (TTI);

[0280] The minimum time granularity of data reporting supported. After collecting the data required by the data plane, how often can the UE support reporting? Based on this capability information, the base station can configure the UE's data collection and schedule data plane resources;

[0281] Indicates the maximum length of a single data plane message supported by the UE, which can be used for data reporting or data reception;

[0285] The request message may include but is not limited to at least one of the following:

[0286] The data collection identifier is unique within the scope of the second node, and is used to identify the second node based on which operations such as modification or deletion of the data collection can be performed;

[0288] Data names, such as RSRP, RSRQ, or Packet Data Convergence Protocol (PDCP) delay, etc. Alternatively, different data names can be represented by defining different values ​​of a certain field, for example, 0000 0001 for RSRP, 0000 0010 for RSRQ, etc.;

[0289] Data region, for example, within a certain RNA region;

[0290] Data generation time, used to indicate the time when the data was generated;

[0291] Data generation location, where, if the data is generated by a base station measuring uplink signals, since the base station is usually located at a fixed position, the data generation location may not be included or the information may be provided only once;

[0292] The data type may include one or more of user contract data, network operation data, perception data, and AI data, or may include data with a data provision identifier or data without a data provision function identifier;

[0293] A data receiving node indication, used to indicate a data receiving node that receives data, wherein the data receiving node may be a data storage function node or a data consumption function node. For example, the data receiving node indication may be a data receiving node identifier;

[0294] The data transmission channel indication is used to indicate the data transmission channel for data transmission. For example, the data transmission channel indication may include a radio bearer identifier, a PDU session identifier, or a data plane transmission bearer identifier.

[0295] The data provided by the data providing node to the second node includes the data collected according to the aforementioned data name. It should be noted that if the same measurement name corresponds to multiple data targets, the corresponding information of the multiple data targets must also be included so that the receiving end can correctly parse the data. The following example illustrates this:

[0296] Example 1: Taking RSRP as an example, the data provided by the data providing node may be a measured value of RSRP, such as -90 dBm.

[0297] Example 2: Taking downlink RSRP as an example, the data provided by the data providing node can be a list, and each data subset in the list includes the cell identifier of the measured downlink RSRP and the measurement value of that time, for example, [cell 1, -90dBm], [cell 7, -70dBm], etc.

[0298] Example 3: Taking downlink RSRP as an example, the data provided by the data providing node includes a plurality of related information corresponding to the data, for example, [data generation time, data generation location, -90 dBm].

[0299] Example 4: The data collection identifier is used as an indication of a set of data-related information. For example, the data collection identifier indicates a set of information such as data target, data name, data area, data generation time, data generation location and data type. Then the data provided by the data providing node includes the data collection identifier and one or more measured data values, for example, [data collection ID, -90dbm, -70dbm, -85dbm, -60dbm], etc.

[0300] In another embodiment, the ninth QoS parameter is determined by the second node. For example, the second node may determine the ninth QoS parameter upon receiving a second message sent by the fourth node for requesting a data service, wherein the second message may include at least one of a data target, a data area, and a data name. For example, the second node may determine the ninth QoS parameter based on a QoS parameter that can be used by the selected data providing node, or based on a QoS parameter that can be used by the second node, or based on a QoS parameter that can be used by the data receiving node, etc.

[0301] Optionally, the method further includes the following:

[0305] In one embodiment, the second node may perform data quality assessment on the data of the received data service according to the ninth QoS parameter, and may send a feedback message to the data receiving node or the sending node of the first message based on the quality assessment result.

[0306] In another embodiment, the second node may send a tenth QoS parameter to the data providing node, wherein the tenth QoS parameter may be the same as the ninth QoS parameter, or the tenth QoS parameter may be partially the same as the ninth QoS parameter. Exemplarily, the tenth QoS parameter may be determined based on the ninth QoS parameter and the QoS parameter used by the first node. For example, when the integrity and redundancy of the data provided by the data providing node are evaluated by the first node, the tenth QoS parameter may include the QoS parameters in the ninth QoS parameter except for the lower limit value of the integrity and the upper limit value of the redundancy. Upon receiving the third message, the data providing node may perform data quality evaluation on the collected data of the data service based on the tenth QoS parameter. The data providing node may include at least one of a UE, an access network node, and a core network node.

[0307] In another embodiment, the third node may send an eleventh QoS parameter to the data receiving node, wherein the eleventh QoS parameter may be the same as the ninth QoS parameter, or the eleventh QoS parameter may be partially the same as the ninth QoS parameter. Upon receiving the fourth message, the data providing node may perform a data quality assessment on the received data of the data service based on the eleventh QoS parameter. The data receiving node may include a data storage function node or a data consumption function node, etc.

[0346] It should be noted that the implementation of this embodiment can refer to the relevant description of the embodiment shown in Figure 2, and will not be described in detail here.

[0347] The following examples illustrate the embodiments of the present application:

[0348] Example 1: QoS parameters for user data transmission are multiplexed, and the first node is a core network node.

[0349] This example uses the case where the first node is a transmission control function in a core network communication service, such as an SMF, and the data service data transmission is performed using the same QoS parameters as the user data transmission in the communication service. Specifically, the following steps may be included:

[0350] Step a1: The second node receives the second message.

[0351] The second node may be a core network node or an access network node. The second message may include at least one of a data target, a data area, a data name, and a ninth QoS parameter.

[0352] Step a2: The second node selects a data providing node based on at least one of the second message, user permission information, and data capability information of the data providing node, and sends a request message to the selected data providing node.

[0353] The request message includes at least one of the following: data collection identifier, data target, data name, data area, data generation time, data generation location, data type, and data receiving node indication.

[0354] If the data providing node rejects the data request, the second node can continue to determine other suitable data providing nodes that can replace the rejected data providing node based on at least one of the second message, user permission information, and data capability information of the data providing node. If suitable data is still not obtained under the corresponding QoS requirement (e.g., response time) constraint, a response message is sent to the sending node of the second message to feedback the reason for the failure. If there is a data providing node that accepts the data request (i.e., can provide data), the second node also needs to determine whether there is a transmission requirement for the required data. If there is a transmission requirement, the required transmission QoS parameters are determined and a first message is sent to the first node (e.g., SMF). The above-mentioned first message may include: a data collection identifier, a first QoS parameter, wherein the first QoS parameter includes at least one of the following: a first QoS identifier; a resource type; a first priority level; a first packet delay budget; and a first packet error rate. Optionally, when the resource type is a guaranteed bit rate (GBR) type, the first QoS parameter also includes at least one of the following: a delay criticality indicator; an averaging window; and a maximum data burst size.

[0355] It should be noted that the above data collection identifier is unique within the scope of the second node. Based on the data collection identifier, the second node can perform operations such as modification or deletion on the data collection.

[0356] Step a3: The first node (eg, SMF) receives the first message and sends QoS parameters, namely the above-mentioned target QoS parameters, to at least one of the access network node, the UE and the UPF.

[0357] Step a4: The data providing node receives the messages sent by the second node and the first node, associates the collected data with the corresponding QoS flow, and sends a first feedback message to the second node, wherein the first feedback message includes the data provided by the data providing node.

[0358] The above-mentioned data providing node may include one or more of a UE, a radio access network node, and a core network node.

[0359] Step a5: The second node receives the first feedback message and performs a data quality assessment on the received data based on the QoS parameters required by the data service (for example, the ninth QoS parameter). If the QoS requirements are met, the data is sent to the sending node of the second message; if the QoS requirements are not met, the reason for the failure is fed back to the sending node of the second message.

[0360] Example 2: Transmitting data using QoS parameters for data services

[0361] This example uses the case where the first node is a transmission control function in a core network communication service, such as an SMF, or a radio access network node responsible for transmission control, such as a gNB or CU, and data service data is transmitted using data service-oriented QoS parameters. Specifically, the following steps may be included:

[0362] Step b1: The second node receives the second message.

[0363] The second node may be a core network node or an access network node. The second message may include at least one of a data target, a data area, a data name, and a ninth QoS parameter.

[0364] Step b2: The second node selects a data providing node based on at least one of the second message, user permission information, and data capability information of the data providing node, and sends a request message to the selected data providing node.

[0365] The request message includes a data collection identifier. Optionally, the request message may further include at least one of the following: data target, data name, data area, data generation time, data generation location, data type, data receiving node indication, and a ninth QoS parameter.

[0366] If the data providing node rejects the data request, the second node may continue to determine other suitable data providing nodes that can replace the rejected data providing node based on at least one of the second message, user permission information, and data capability information of the data providing node. If suitable data is still not obtained under the corresponding QoS requirement (for example, response time) constraint, a response message is sent to the sending node of the second message to feedback the reason for the failure. If there is a data providing node that accepts the data request (that is, it can provide data), the second node also needs to determine whether the required data has transmission requirements. If there are transmission requirements, the required transmission QoS parameters are determined and a first message is sent to the first node, wherein the first message may include: a data collection identifier, a first QoS parameter, wherein the first QoS parameter includes at least one of the following: a second QoS identifier, a second packet delay budget, a transmission resource type, a second priority level, a second packet error rate, a notification control indication, and a maximum packet loss rate.

[0367] It should be noted that the above data collection identifier is unique within the scope of the second node. Based on the data collection identifier, the second node can perform operations such as modification or deletion on the data collection.

[0368] Step b3: The first node receives the first message and sends QoS parameters to at least one of the access network node, the UE, and the core network node according to the first message. The following is an explanation of the following situations:

[0369] Case 1: The above-mentioned access network node, UE or core network node serves as a data providing node.

[0370] For the UE as a data providing node, the QoS parameters sent by the first node to the UE include at least a data collection identifier and a radio bearer identifier. The default management granularity of the transmission QoS of the data service is at the radio bearer level, that is, the QoS parameters are associated with a certain radio bearer. In the case where a radio bearer can transmit QoS flows corresponding to multiple data services, finer-grained QoS management is required, for example, QoS flow-level QoS management. In this case, the QoS parameters sent to the UE may also include a QoS flow identifier. Specifically, the UE classifies and marks the collected data according to the received QoS parameters, and associates it with the corresponding radio bearer or the QoS flow of the radio bearer.

[0371] When the access network node functions as a data providing node, the QoS parameters sent by the first node to the access network node include a data collection identifier, a data transmission bearer identifier, and the first QoS parameters. Specifically, the access network node classifies and labels the collected data based on the received QoS parameters, associates the collected data with the corresponding data transmission bearer, and uses the first QoS parameters for transmission control.

[0372] For a core network node serving as a data providing node, the QoS parameters sent by the first node to the core network node include a data collection identifier and a data transmission bearer identifier. Specifically, the core network node classifies and marks the collected data according to the received QoS parameters and associates it with the corresponding data transmission bearer.

[0373] Case 2: The access network node, UE or core network node serves as a node for transmitting or forwarding data for the data service between the data providing node and the data receiving node.

[0374] The QoS parameters sent by the first node to the access network node, UE, or core network node include data detection rules and data forwarding rules, wherein the data detection rules include a data providing node identifier and a data receiving node identifier, and the data forwarding rules include first indication information, wherein the first indication information is used to indicate whether to forward, discard, or cache data detected by the data detection rules. Specifically, the access network node, UE, or core network node can identify data flows of different data services based on the data detection rules and perform data forwarding processing based on the data forwarding rules.

[0375] It should be noted that the information sent by the first node to the access network node also includes the first QoS parameter. Accordingly, the access network node can identify data flows of different data services according to the data detection rule, perform data forwarding processing according to the data forwarding rule, and perform data transmission control based on the first QoS parameter.

[0376] Step b4: If the request message sent by the second node received by the data providing node includes the QoS parameters of the required data (i.e., the tenth QoS parameter mentioned above), then the collected data is evaluated based on the tenth QoS parameter to determine whether the QoS is met, and based on the judgment result, the first feedback information is sent to the second node. If the request message sent by the second node received by the data providing node does not include the QoS parameters of the required data, then the data providing node does not need to perform a QoS evaluation. The data providing node receives messages sent by the second node and the first node, associates the data to the corresponding QoS flow or data transmission bearer, and sends the first feedback information to the second node. The first feedback information includes at least one of the data provided by the data providing node and an indication that the QoS is not met.

[0377] The data providing node may include one or more of a UE, a radio access network node, and a core network function node.

[0378] Step b5: The second node receives the first feedback information. If the request message sent by the second node does not include the QoS parameters of the required data, the second node performs data quality evaluation on the received data according to the QoS required by the data service (i.e., the ninth QoS parameter). If the QoS is met, the data is sent to the sending node of the second message. If the QoS is not met, the reason for the failure is fed back. If the request message sent by the second node includes the QoS parameters of the required data, the second node can feed back the data provided by the data providing node to the sending node of the second message.

[0379] In summary, the solution provided by the embodiment of the present application can solve the QoS parameter definition required for interaction between nodes in a mobile communication network for data services with delay requirements. In particular, when the required data is not transmitted through the control plane, the QoS definition and interaction process provided by the embodiment of the present application can solve the data service quality definition and guarantee problems including data transmission quality parameter control. If a QoS similar to user data transmission is adopted, the processes and most parameter definitions in the relevant technologies can be reused to meet the data transmission requirements of user-plane-based data services. If a data service-oriented QoS definition is adopted, QoS parameters can be defined more accurately and simply for data service characteristics. In addition, the solution provided by the embodiment of the present application not only supports QoS parameter control of data transmission between UE and core network forwarding nodes, but also supports the configuration and control of parameters such as data transmission delay between UE and RAN, which can meet the requirements of flexible termination of data required by data services at UE, RAN and CN.
