The relevant technical points involved in this application will first be described below.

1. Association between 5G Quality of Experience (QoE) and Minimization of drive tests (MDT)

When the user equipment (User Equipment, UE, also called terminal) application layer measures configuration information, when configuring QoE, it is indicated that it is associated with the MDT of a certain trace identity (Trace ID). The correlation requirement between MDT and QoE is that the QoE collection time is uncontrollable by the base station because it is not sure when the terminal will have corresponding services. If efficiency is not considered, the base station will always perform MDT measurements regardless of whether the UE has QoE collection, and finally both information will be reported to the Trace Collection Entity (TCE) based on the UE ID and trace ID correlation.

Regarding data collection time alignment, R17 introduces an enhancement that will notify the base station after QoE is started, and then the base station can start configuring MDT. After QoE is reported to the base station, the base station can stop MDT to achieve time alignment between the two.

2. Potential data association scenarios

The first function node that configures data collection configures data collection configuration information to one or more second function nodes, and the configured data collection configuration information needs to be associated for processing in some cases. Further, according to whether the second function node is known to the first function node when collecting configuration information in the configuration data, it can be divided into two types: the first function node directly configures all the second function nodes and the first function node indirectly configures part of the second function node. Condition.

2.1. Scenario 1 where the first function node that configures data to collect configuration information directly configures all second function nodes

During sensing, sensing signals and measurements are collected through UE and/or inter-base station transceiver (such as UE spontaneous self-receiver, inter-UE transceiver, UE transmits to base station and receives, base station transmits to UE and receives, base station spontaneous self-receiver, inter-base station transceiver) sensing signals and measurements. . In some scenarios, other sensing auxiliary data (such as camera information, channel status information of non-3rd Generation Partnership Project (3GPP) access nodes, etc.) are required while the above-mentioned transceiver and measurement are required. When the sensing function (Sensing Function, SF) When determining the required UE, base station and/or sensing auxiliary data node and directly configuring the data collection configuration information, this scenario is a scenario where the first function node that configures data collection knows all the second function nodes. If the aforementioned sensing measurement data and sensing assistance data of the UE or base station are collected completely independently, the node that provides the sensing assistance data usually needs to provide data for a longer period of time. If the association is based on timestamps, then timestamp information is added to the data at each time point. The cost is also larger.

Examples are given below.

Example 1: When the vehicle is a UE with 3GPP access function, the sensing function configures roadside units (such as base stations or stationary UEs), base stations, etc. for the vehicle for sensing to assist its intelligent driving. Typically, the vehicle is based on its own Radars and cameras perform information perception and intelligent driving decisions. When encountering special circumstances (such as heavy fog, special terrain that prevents cameras and/or radars from being perceived, traffic jams for unknown reasons, etc.), the perception function needs to quickly obtain the perception of roadside units, base stations, etc. near the vehicle it is configured with. Measurement data, and/or perception data from the vehicle's own radar and/or camera, are correlated and processed to produce high-precision perception results. In this scenario, it is difficult for the perception function to predict when the vehicle will need roadside units or base stations for collaborative sensing. If the vehicle reports information such as its own radar and/or camera, continuous sensing by roadside units or base stations will waste air interface resources and Aware of data transmission resources.

Example 2: According to the sensing function and base station configuration, the UE sends a sensing signal. When the base station receives the sensing signal and makes measurements, it collects the sensing measurement data of the base station and provides it to the sensing function. Correspondingly, when the base station configures the UE to send sensing signals, other sensing assistance data nodes (such as nodes in 3GPP access mode or non-3GPP access mode) need to provide sensing assistance data to the sensing function at the corresponding time. It is assumed here that the sensing function knows non-3GPP access nodes that can provide sensing assistance information (for example, the non-3GPP access node has been registered with the sensing function, so the sensing function can select and configure it). Because the real-time resource scheduling of the air interface is handled by the base station rather than the sensing function, it is difficult to configure the precise auxiliary information collection time for the sensing function. The base station's sensing measurement data and sensing auxiliary data are collected completely independently, and nodes that provide sensing auxiliary data usually need to provide data for a longer period of time. If the perception measurement data and the perception auxiliary data are associated based on timestamps, then the cost of adding timestamp information to the data at each time point is also high.

It should be noted that the sensing assistance data can be transmitted through the access method defined by 3GPP (such as other wifi nodes reporting to the sensing function through the UE), or through the non-3GPP access method (such as other wifi nodes reporting directly to the sensing function). Function).

2.2. Scenario 2 in which the first function node that configures data to collect configuration information directly configures all second function nodes

Distributed collaborative computing usually requires different nodes to perform collaborative computing processing with similar delays (transmission delay plus calculation delay). The service experience of computing services is determined by the collaborative computing performance of different computing nodes. Therefore, for computing services with high service experience requirements, when the UE or application function (Application Function, AF) feeds back computing service experience data (such as QoE or Quality of Service) Service, QoS)), each computing node needs to collect performance data such as transmission delay and computing delay accordingly. The correlation between computing service experience data and performance data can be used to analyze and predict computing service experience or optimize network configuration to ensure computing service quality. If the computing service experience data of computing demand nodes and the performance data such as latency of each computing node are collected independently, there will also be problems such as the need for continuous collection over a long period of time and the high cost of associated timestamps.

2.3. Scenario 1 in which the first functional node that collects configuration information from configuration data indirectly configures some second functional nodes.

During sensing, sensing signals and measurements are collected through UE and/or inter-base station transceiver (such as UE spontaneous self-receiver, inter-UE transceiver, UE transmits to base station and receives, base station transmits to UE and receives, base station spontaneous self-receiver, inter-base station transceiver) sensing signals and measurements. . When in some scenarios other sensing auxiliary data (such as camera information, channel state information of non-3GPP access nodes, etc.) are required while the above transceiver and measurement are performed, when the sensing function determines the required UE, base station and/or sensing auxiliary data When the node directly or indirectly configures the data collection configuration information, this scenario is a scenario in which the first function node that configures the data collection configuration information indirectly configures some second function nodes. If the aforementioned sensing measurement data and sensing assistance data of the UE or base station are collected completely independently, the node providing sensing assistance data usually needs to provide data for a longer period of time. If the correlation is based on timestamps, If the data is connected, the cost of adding timestamp information to the data at each time point is also large.

Examples are given below.

Example 1: According to the sensing function and base station configuration, the UE sends a sensing signal. When the base station receives the sensing signal and makes measurements, it collects the sensing measurement data of the base station and provides it to the sensing function. Accordingly, considering requirements such as sensing accuracy and UE capability information, the sensing function configures the UE to assist in providing sensing assistance data. For example, in home scenarios, 3GPP access devices or non-3GPP access devices (such as smart desk lamps, smart speakers, bracelets, watches, etc.) connected to the UE through sidelink, WiFi, and Bluetooth can assist. Provides sensing auxiliary data such as channel status, blood oxygen, etc. Then when the base station configures the UE to send sensing signals, other sensing assistance data nodes (which can be 3GPP access methods or non-3GPP access methods) need to provide sensing assistance data to the sensing function at the corresponding time. The sensing function here focuses more on sensing auxiliary data rather than who provides the data. Therefore, the sensing function only needs to configure sensing auxiliary data information, and does not need to know other sensing auxiliary data providing node information connected to the UE. If the aforementioned sensing measurement data and sensing assistance data of the UE or base station are collected completely independently, the node providing the assistance information usually needs to provide data for a longer period of time. If the association is based on timestamps, then the timestamp information is added to the data at each time point. The overhead is also larger.

As can be seen from the above content, when a certain data collection occurs at an unpredictable time, such as the time required to initiate sensing or calculation, the time to collect quality of service information for sensing or calculation, the time-frequency resource scheduling time for air interface sensing, etc., there are long-term problems in related technologies. Time data collection, which leads to problems such as long data collection time and high overhead of associated timestamps.

In the embodiment of this application, the so-called associated data refers to data with an associated relationship. For example, the perceptual measurement data uploaded by a certain node at a certain time has an associated relationship with the perceptual auxiliary data uploaded by other nodes. Then the above-mentioned perceptual measurement data and perception auxiliary data are associated data.

In some other embodiments, sensing measurements are performed on the UE and/or the base station, and other nodes (nodes in the 3GPP access mode or nodes in the non-3GPP access mode) provide sensing assistance data at the sensing signal transmission time. The first functional node is still a sensing function, and the second functional node is a UE, a base station and a sensing assistance data providing node that perform signal transmission and reception determined by the sensing function. If the node that provides sensing assistance data is a node that supports the 3GPP access mode, then the base station that determines the sensing signal transmission time resource is the third functional node (if the base station is responsible for sending sensing signals but not receiving and measuring, then the base station is not the third functional node). Second function node; accordingly, if the base station is responsible for receiving sensing signals and measurements, then the base station is both the second function node that provides data collection and the third function node that triggers data collection). After the base station determines the time resource for sensing signal transmission, it sends associated data collection instruction information to the second functional node that provides sensing assistance data based on the time resource information, so that the sensing assistance data providing node starts and/or terminates assistance. Data collection and reporting. If the node that provides sensing assistance data is a non-3GPP access mode node, it is assumed that the UE that sends or receives sensing signals can interact with the sensing assistance data providing node, so the UE is a third function node (if the UE If the UE is responsible for sending sensing signals but not for receiving and measuring, then the UE is not the second functional node; accordingly, if the UE is responsible for receiving sensing signals and measuring, then the UE is the second functional node that provides data collection and also triggers data collection. third function node).

Data collection and reporting. Therefore, the main difference between this example and the above-mentioned smart driving scenario is that the third function node is not the node that provides sensing assistance data, but the base station that determines the time domain resources for sending sensing signals or the UE that receives sensing signal configuration information.

Similarly, for collaborative computing scenarios, the network function responsible for data collection of computing nodes is the first function node, and the computing demand node and computing node are the second functional nodes that need to be associated for data collection. At the same time, the computing demand node is also the second functional node. Three function nodes. The first function node configures the data that needs to be collected to the second function node. For example, the computing demand node collects computing service experience data (such as video freeze information, buffer status, etc.), and the computing node collects data reception time and computing delay. Wait for data. The first function node sends associated data collection configuration information to the third function node, indicating that the first trigger condition is that the third function node collects computing service experience data. Considering that this solution is mainly oriented to the transmission of computing data between computing demand nodes and computing nodes, when a certain computing business of the third functional node has high computing performance requirements (such as virtual digital humans, etc.), then the third functional node can Determine the collection of computing service experience data, as well as the time interval and frequency of collection, etc. Then, according to the configuration of the first function node, the third function node sends the associated data collection instruction information to the computing node (second function node), and the computing node collects and reports the associated data based on the received associated data collection instruction information.

Among them, the data collection configuration information includes at least one of the following:

1) The identification of the collected data; if it is already included in the associated data collection configuration information, it does not need to be included in the data collection configuration information.

According to the requirements of network functions for processing relevant data), the configuration of data collection is unified. Therefore, in this embodiment of the present application, the data plane function is the first function node, and the node that provides data is the second function node. According to the association relationship between multiple parties, the first function node determines the third function node and sends the associated data collection configuration information to the third function node.
