[0040] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0041] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0042] The specific implementation of the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0043] Figure 1 A schematic diagram of an exemplary application system architecture to which the data collection method in the embodiments of the present disclosure can be applied is shown.

[0044] like Figure 1 As shown, the system architecture includes a terminal device 101, a network 102 and a network-side device 103; the network 102 is used to provide a medium for a communication link between the terminal device 101 and the network-side device 103, and can be a wired network or a wireless network.

[0045] Optionally, the wireless network or wired network described above uses standard communication technology and / or protocol. The network is typically the Internet, but may also be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a dedicated network or any combination of a virtual private network. In some embodiments, the data exchanged through the network is represented using technology and / or formats including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML), etc. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPsec) may be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies may also be used to replace or supplement the above data communication technologies.

[0046] Figure 1 Any terminal device 101 shown can be used as a wireless access network node for data collection.

[0047] Optionally, the terminal device 101 in the embodiment of the present disclosure may also be referred to as UE (User Equipment). In a specific implementation, the terminal device 101 may be a terminal-side device such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device.

[0048] Optionally, the client of the application installed in different terminal devices is the same, or the client of the same type of application based on different operating systems. Based on the different terminal platforms, the specific form of the client of the application can also be different, for example, the application client can be a mobile client, a PC client, etc.

[0049] The network side device 103 includes various network entities of the access network or core network, including but not limited to access and mobility management function (Access and Mobility Management Function, AMF) network element, network data analysis function (Network Data Analytices Function, NSACF) network element, in addition, it can also include location management function (Location Management Function, LMF), session management function (Session Management Function, SMF) network element, unified data management (Unified Data Management, UDM) network element, user plane function (User Plane Function, UPF) network element and policy control function (Policy Control Function, PCF) network element, etc. It should be noted that the specific type of network side equipment is not limited in the embodiment of the present disclosure.

[0050] like Figure 1 As shown in the figure, the AMF network element supports UEs with different mobility management requirements. The PCF network element interacts with the access and mobility policy implementation in the AMF network element through the service-based interfaces (SBI); the UDM network element is part of the 5G core network control plane and is the front-end architecture of the 5G user database. The LMF network element manages the resources and time of positioning activities and connects the Gateway Mobile Location Center (Gateway Mobile Location Center) to the UE. The positioning service of the 5G network is exposed to the AMF network element for immediate or delayed location information requests on the NL1 interface; the UDM network element is the user subscription data management part of the control plane, responsible for the processing of business logic, responsible for signaling processing between other core network elements, and saves dynamic data of users and services; the UE sends a subscription data request to the UDM network element through the AMF network element for user registration; the SMF network element is used to establish a session and configure the flow control of the UPF network element to route the traffic to the correct destination. As a 5G network user plane network element, the UPF network element mainly supports the routing and forwarding of UE service data, data and service identification, action and policy execution, etc.; the NSACF network element is used to monitor the characteristics of the number of UEs and the number of PDU sessions of each network slice belonging to the NSAC, and match the network slice for the UE. The UPF network element interacts with the SMF network element through the N4 interface, is controlled and managed by the SMF network element, and executes the processing of service flows according to various policies issued by the SMF network element. In other words, after the SMF network element receives the session policy control creation response from the PCF network element, it controls the UPF network element to execute the processing of service flows.

[0051] In 3GPP, the physical interface between the 5G radio access network RAN ​​and the AMF network element is defined as the NG interface, and the protocol is NGAP.

[0052] The NGAP protocol can provide signaling interaction between NG-RAN nodes and AMF network elements, implement non-UE services, provide non-UE signaling links and application instances related to the entire NG interface between NG-RAN nodes and AMF network elements; and implement UE services, provide single UE services, and provide and maintain NG signaling links for terminals.

[0053] Exemplarily, the 5G wireless access network and the AMF network element can be connected through the N2 interface. The AMF network element and another AMF network element can be connected through the N14 interface. The AFM network element and the NWDAF network element are connected through the interface of the Namf service. The AMF network element and the SMF network element are connected through the N11 interface. The AFM network element and the LMF network element are connected through the NLs interface.

[0054] Those skilled in the art will know that Figure 1 The number of terminal devices, networks, and network-side devices in the example is merely illustrative, and any number of terminal devices, networks, and network-side devices may be provided according to actual needs. The embodiments of the present disclosure do not limit this.

[0055] The 3GPP SA2 working group introduced AI into the 5G core network architecture and added the Network Data Analytics Function (NDAF) network element, which collects raw data through other network function (Network Function) network elements, application function (Application Function, AF) network elements, operation administration and maintenance (OAM) or radio access network (Radio Access Network, RAN) network elements, and performs intelligent analysis on the raw data, and outputs the analysis results to NF network elements, AF network elements, OAM, etc., for optimizing networks and services. Its application scenarios cover network slice selection, quality of service (Quality of Service, QoS) decision-making, mobility management, load balancing, UPF selection, network performance prediction, etc.

[0056] In the Functional Framework for RAN Intelligence, Data Collection is a functional module that provides input data for the Model Training and Model Inference functions. The input data may include measurements from terminals or different network entities, performance feedback, and AI / ML model outputs. The data types include training data (information required for model training) and inference data (input information required for model inference).

[0057] In wireless network intelligent applications, the quality of data will seriously affect the performance of AI algorithms. Missing or damaged data will cause the AI ​​model to overfit, making it impossible to make accurate predictions, thereby reducing the overall performance of the wireless system.

[0058] In order to solve the above technical problems, the solution provided by the embodiment of the present disclosure is that the first AMF network element sends a first signaling to the first wireless access network node, the first signaling is used to request data or information from the first wireless access network node, and carries relevant indication information of the data or information; receives a second signaling sent by the first wireless access network node, the second signaling is used to indicate that the first wireless access network node accepts the request, and carries relevant indication information of the measurement parameters; receives a third signaling sent by the first wireless access network node, the third signaling carries data or information report, and expands the NG interface function under the existing network architecture, supports AI data collection and transmission processes based on the NG-interface, improves the completeness of data collection in wireless AI scenarios, improves the efficiency of wireless AI model training, and thus ensures the accuracy of wireless AI algorithm predictions. It is specifically described through the following embodiments:

[0059] First, a data collection method is provided in an embodiment of the present disclosure, and the method can be executed by any system with computing processing capabilities. In a feasible implementation, the process corresponding to the method can be executed by the first AMF network element; in another feasible implementation, the process corresponding to the method can be executed by the first wireless access network node, such as a base station; in other feasible implementations, the process corresponding to the method can also be implemented by the interaction between the first AMF network element and the first wireless access network node.

[0060] Figure 2 A flow chart of a data collection method in an embodiment of the present disclosure is shown as follows: Figure 2 As shown, the data collection method provided in the embodiment of the present disclosure is applied to the first AMF network element, comprising the following steps:

[0061] S202. Send a first signaling to a first radio access network node, where the first signaling is used to request data or information from the first radio access network node and carries relevant indication information of the data or information.

[0062] In one embodiment, the relevant indication information of the data or information includes one or more of the following information: data collection time information, data collection granularity information, and data collection parameter information.

[0063] The data collection time information is used to determine the time range of data collection to instruct the first radio access network node to collect data within the above time range. At the same time, the data collection time information can also be used as a basis for data reporting conditions.

[0064] The data collection time information includes at least one of a reporting period; a measurement or data collection start time, a measurement or data collection end time; and a measurement or data collection start time, a measurement or data collection duration.

[0065] For example, the reporting period can be 500ms, 1000ms, 2000ms, 5000ms, 10000ms, etc., which can be determined according to actual conditions.

[0066] The measurement or data collection start time and the measurement or data collection end time are determined according to actual conditions, and this disclosure does not make any specific limitations.

[0067] The above measurement or data collection duration may be 500ms, 1000ms, 2000ms, 5000ms, 10000ms, etc., and may be determined according to actual conditions.

[0068] Among them, the reporting period corresponds to the periodic reporting method; the other two parameters can correspond to the One-time reporting method.

[0070] The data collection granularity information includes at least one or more wireless access network node identifiers; one or more cell identifiers; one or more synchronization signal block (SSB) identifiers or indexes; and at least one of one or more slice identifiers.

[0071] The data collection parameters are used to characterize the different types of data that the first wireless access network node needs to collect, that is, the various training data that need to be input when the AI ​​model performs model training.

[0072] It should be noted that the data collection parameter information at least includes the radio resource status (Radio Resource Status) or the predicted radio resource status; the network energy efficiency status (Network Energy Efficiency Status) or the predicted network energy efficiency status; the number of active users (Number of Active UEs) or the predicted number of active users; the number of radio resource control (Radio Resource Control, RRC) connections (Number of Active UEs) or the predicted number of radio resource control connections; UE historical trajectory or predicted UE trajectory; network energy efficiency or predicted network energy efficiency; average uplink or downlink throughput of the terminal (Average UE UL / DL Throughput); average data transmission delay of the terminal (Average UE Packet Delay); and average packet loss rate of the terminal (Average UE Packet Loss Rate).

[0074] In one embodiment, the first AMF network element sends a first signaling to the first radio access network node through the NG interface, which is used to request data or information from the first radio access network node and carry relevant indication information of the data or information. The NG interface is open to the radio access network and the core network, supports the signaling information interaction between the radio access network and the core network, and is a point-to-point logical interface between the radio access network node and the core network node. Even if there is no direct physical connection between the radio access network and the core network, a point-to-point logical link can be achieved through the NG interface.

[0075] S204: Receive second signaling sent by the first radio access network node, where the second signaling is used to instruct the first radio access network node to receive a request and carries indication information related to a measurement parameter.

[0076] In one embodiment, the first radio access network node sends a second signaling, or Data Conllection Confirm, to the first AMF network element based on the relevant indication information of the data or information carried in the first signaling, if the first radio access network node can provide all or part of the reporting information indicated in the first signaling. The second signaling is used to instruct the first radio access network node to receive the request, and carries the relevant indication information of the measurement parameter, and reports the data type that can be collected.

[0077] It should be noted that the measurement parameter related indication information includes at least one of the following information: the measurement parameter / target of the accepted request; the measurement parameter / target of the failed request; and the measurement parameter / target of the supported request.

[0078] The measurement parameters / targets for which the request is accepted are all or part of the parameters in the relevant indication information of the data or information measured by the first radio access network node, and correspondingly, the failed measurement parameters / targets are the parameters in the relevant indication information of the data or information that the first radio access network node cannot measure. The supported measurement parameters / targets are the parameters of the first radio access network node other than the parameters specified in the relevant indication information of the data or information.

[0079] S206: Receive a third signaling sent by the first radio access network node, where the third signaling carries data or an information report.

[0080] It should be noted that the data or information report contains at least one of the following information: wireless resource status or predicted wireless resource status; network energy efficiency status or predicted network energy efficiency status; number of active users or predicted number of active users; number of wireless resource control connections or predicted number of wireless resource control connections; UE historical trajectory or predicted UE trajectory; network energy efficiency or predicted network energy efficiency; average uplink or downlink throughput of the terminal; average data transmission delay of the terminal; and average packet loss rate of the terminal.

[0081] In the disclosed embodiment, the first AMF network element sends a first signaling to the first wireless access network node, the first signaling is used to request data or information from the first wireless access network node and carries relevant indication information of the data or information; receives a second signaling sent by the first wireless access network node, the second signaling is used to instruct the first wireless access network node to receive the request and carries relevant indication information of the measurement parameters; receives a third signaling sent by the first wireless access network node, the third signaling carries a data or information report, and expands the NG interface function under the existing network architecture, supports AI data collection and transmission processes based on the NG-interface, improves the completeness of data collection in wireless AI scenarios, and improves the efficiency of wireless AI model training, thereby ensuring the accuracy of wireless AI algorithm predictions.

[0082] Figure 3Another data collection method flow chart provided in the embodiment of the present disclosure is shown. Figure 2 Based on the embodiment, S208 is added to limit the situation where the first radio access network node cannot provide all the reporting information indicated in the first signaling. Figure 3 As shown, the data collection method provided in the embodiment of the present disclosure includes S202 to S208. The method includes:

[0083] S208. Receive a fourth signaling sent by the first radio access network node, where the fourth signaling is used to indicate a data or information request failure.

[0084] It should be noted that the specific implementation of S202 to S206 in this embodiment is the same as the specific implementation of S202 to S206 in the aforementioned embodiment, and will not be repeated here.

[0085] In one embodiment, when the first wireless access network node cannot provide all the reporting information indicated in the first signaling, the first wireless access network node sends a fourth signaling, or Data Collection Failure, to the first AMF network element, indicating that the data request failed.

[0086] It should be noted that the above-mentioned first signaling, second signaling, third signaling, and fourth signaling are all interactive signaling between the first wireless access network node and the first AMF network element, and the above-mentioned signaling can be transmitted through the NG interface.

[0087] In an embodiment of the present disclosure, when the first wireless access network node is unable to provide all the reporting information indicated in the first signaling, the fourth signaling indicates the data request failure information to the first AMF network element so that the first AMF network element can process it in time to ensure the timeliness of AI model training.

[0088] Through the above S202~S208, it is possible to transmit data collection requirements between NG interfaces and complete the data reporting process. This solution can be applied to scenarios where the first wireless access network node needs to collect and report data in an infinite intelligent network scenario. The requirement can be triggered by a core network element or other wireless access network node (a wireless access network node that has no Xn interface with the first wireless access network node). The collected data can be used for AI model training or AI model reasoning, so as to predict the state of the wireless network or user behavior, perform intelligent management of the wireless network, and improve the overall performance of the wireless network.

[0090] S201. Receive the fifth signaling sent by the node that initiates the data or information request, where the fifth signaling is used to request the first AMF network element to request data or information from the first wireless access network node, and carries relevant indication information of the data or information, wherein the node that initiates the data or information request includes the second wireless access network node and other core network network elements, and the other core network network elements include at least one of the following: a second AMF network element, a NWDAF network element, a LMF network element, and an SMF network element.

[0091] It should be noted that the fifth signaling includes one or more of the following: wireless access network node identification or index; reporting period; measurement or data collection start time, measurement or data collection end time; measurement or data collection start time, measurement or data collection duration; one or more cell identification IDs; one or more synchronization signal block SSB identification IDs or indexes; one or more slice identification IDs; wireless resource status; network energy efficiency status; number of active users; number of wireless resource control connections; average uplink or downlink throughput of the terminal; average data transmission delay of the terminal; average packet loss rate of the terminal. Among them, the wireless access network node identification or index is used to determine the node for data or information collection.

[0092] Exemplarily, the node that initiates the data or information request may be a second radio access network node, and the second radio access network node is a node that has no Xn interface with the first radio access network node.

[0093] Exemplarily, the node that initiates the data or information request may be other core network elements other than the first AMF network element, or may be other third-party network elements.

[0094] In an embodiment of the present disclosure, the trigger node triggers the first AMF network element to send collected data, so that the collected data is used for AI model training or AI model reasoning to improve the overall performance of the wireless network.

[0095] Figure 5 A flow chart of another data collection method provided by an embodiment of the present disclosure is shown. Figure 4 On the basis of the embodiment, S205 is added after S204 to limit the situation in which the first radio access network node accepts the request; S207 is added after S206 to limit the situation in which the data or information report is fed back. Figure 5 As shown, in one embodiment, the data collection method provided by the embodiment of the present disclosure, after receiving the second signaling sent by the first radio access network node in S204, further includes:

[0096] S205. Send a sixth signaling to the node that initiates the data or information request, where the sixth signaling is used to respond to the data or information request and carries indication information related to the measurement parameter;

[0097] After receiving the third signaling sent by the first radio access network node in S206, the method further includes:

[0098] S207: Send a data or information report to the node that initiated the data or information request.

[0099] In one embodiment, the data collection method provided by the embodiment of the present disclosure further includes: sending a seventh signaling to the node that initiates the data or information request, where the seventh signaling is used to indicate that the data or information request fails.

[0100] It should be noted that the fifth signaling, the sixth signaling and the seventh signaling are inter-interface signaling.

[0101] In an embodiment of the present disclosure, when the first wireless access network node feedback accepts the request and carries relevant indication information of the measurement parameters, the above information is immediately fed back to the node that initiated the data or information request. When the data or information request fails, the request failure information is fed back to the node that initiated the data or information request, thereby supporting the AI ​​data collection and transmission process based on the NG-interface and ensuring the accuracy of the wireless AI algorithm prediction.

[0102] Figure 6 A flow chart of a data collection method provided by an embodiment of the present disclosure is shown. Figure 6 As shown, in one embodiment, the data collection method provided by the embodiment of the present disclosure is applied to a first wireless access network node, including:

[0103] S602. Receive a first signaling sent by a first AMF network element, where the first signaling is used to request data or information from a first radio access network node and carries relevant indication information of the data or information;

[0104] S604. Send a second signaling to the first AMF network element, where the second signaling is used to instruct the first radio access network node to accept the request and carries indication information related to the measurement parameter;

[0105] S606. Perform measurement, generate data or information report, and send a third signaling to the first AMF network element, where the third signaling carries the data or information report.

[0106] Continue to refer Figure 6 In one embodiment, after receiving the first signaling sent by the first AMF network element in S604, the method further includes: sending a fourth signaling to the first AMF network element, the fourth signaling being used to indicate a data or information request failure.

[0107] In one embodiment, during the data collection process of the first wireless access network node according to the data collection parameters carried in the first signaling, it is determined in real time whether the reporting conditions are met. If the reporting conditions are met, the first wireless access network node reports the collected data to the first AMF network element through the third signaling.

[0108] The above reporting conditions are determined based on the data collection time information and reporting method.

[0109] For example, for a periodic reporting method, when a reporting period is reached, it is determined that the reporting condition is met, and the first radio access network node reports data.

[0110] For the One-time reporting method, when the measurement or data collection time reaches the measurement or data collection end time, or when the measurement or data collection duration reaches the measurement or data collection duration, it is determined that the reporting condition is met, and the first wireless access network node reports the data.

[0111] In one embodiment, after receiving the first signaling sent by the first AMF network element in S802, the method also includes: sending a fourth signaling to the first AMF network element, the fourth signaling being used to indicate that the first AMF network element data request failed.

[0112] It should be noted that the implementation method of the data collection method on the first wireless access network node side can refer to the implementation method on the first AMF network element side, which will not be repeated here.

[0113] In the current data collection process designed by 3GPP around AI, only the AI-related information interaction process of the Xn interface between base stations is involved, the data collection granularity is only at the cell level, and the reported parameters are relatively limited. In this disclosure, multiple NG interface signalings are added, so that the data collection process can be implemented based on the NG-interface, and the SSB-level and Slice-level data collection granularity are increased, so that the collected data can be more refined and can meet the AI ​​model training needs in various application scenarios.

[0114] The core network and wireless access network need to collaborate to support more types of intelligent application scenarios and support data collection processes triggered by core network elements.

[0115] For the data collection process triggered by the base station, when there is no Xn interface or the Xn interface is unavailable between the source base station (first wireless access network node) and the target base station (second wireless access network node), the data collection process can also be implemented through the NG interface, thereby expanding the data collection path and increasing the completeness of the network AI data set.

[0116] The data collection method provided by the present disclosure is highly compatible with existing protocols and has strong applicability.

[0117] It should be noted that the implementation method on the first wireless access network node side can refer to the implementation method on the first AMF network element side, which will not be repeated here.
