[0081] As shown in Figure 1A, the communication system 100 includes an access network device 101 and a core network device 102. The core network device can communicate with the terminal and the core network device.

[0086] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0087] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0088] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto.

[0089] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0090] In some embodiments, AI-based positioning can be mainly divided into two categories: direct AI / ML positioning and AI / ML assisted positioning, where ML refers to machine learning.

[0091] In some embodiments, direct AI positioning may include the following three scenarios:

[0092] Scenario 1: Terminal-based positioning is achieved through a model on the terminal side.

[0093] Case 2b: Positioning is performed based on the terminal or LMF through the model on the LMF (Location Management Function) side.

[0094] Case 3b: Access network equipment is located using the model on the LMF side.

[0095] In some embodiments, AI-assisted positioning may include the following two scenarios:

[0096] Case 2a: Positioning based on the terminal or LMF using a model on the terminal side.

[0097] Case 3a: The location of the access network device is assisted by the model on the access network device side.

[0098] Among them, the access network equipment can be, for example, NG-RAN (Next Generation Radio Access Network).

[0099] In some embodiments, the positioning and data acquisition transactions between the LMF and access network devices can be modeled, for example, using the NRPPa (New Radio Positioning Protocol A) procedure. There are two main types of NRPPa procedures:

[0100] Terminal-related processes, namely information transmission for specific terminals, include processes that support the transmission of location information, e-CID (Enhanced Cell ID) location information, and measurement pre-configuration information.

[0101] Non-terminal related processes, which are applicable to information transmission between NG-RAN nodes and related TRPs (Transmission and Reception Points), include processes that support OTDOA (Observed Time Difference of Arrival) information transmission, auxiliary information transmission, TRP information transmission, measurement information transmission, and PRS (Positioning Reference Signals) information transmission.

[0102] In some embodiments, the NRPPa procedure can support parallel interaction between the same LMF and NG-RAN nodes; for example, a pair of LMF and NG-RAN nodes can execute multiple instances of the NRPPa procedure simultaneously. For possible scalability, the NRPPa protocol can run between generic "access nodes" (e.g., gNB, ng-eNB) and "servers" (e.g., LMF). However, NRPPa interactions are only initiated by the server.

[0103] Figure 1B is a schematic diagram illustrating an NRPPa interaction according to an embodiment of the present disclosure.

[0104] As shown in Figure 1B, in the first step, the LMF first sends a request for the NRPPa procedure to the access network device, and in the second step, the access network device sends a response to the LMF.

[0105] In the process including OTDOA information exchange, TRP information exchange, PRS configuration exchange and measurement pre-configuration, the interaction shown in Figure 1B terminates in step 2.

[0106] For procedures such as location information exchange, measurement, and E-CID measurement initiation, additional responses may be permitted (e.g., sending updated information periodically and / or whenever there are significant changes). In this case, the interaction may end after some additional responses. In the NRPPa protocol, the described interaction can be implemented by executing a process defined as a request and response, and then the access network device initiates one or more processes (each process defined as a single message) to implement additional responses. When the LMF calls the Namf_Communication_N1N2MessageTransfer AMF service operation to transfer an NRPPa PDU (Protocol Data Unit), the relevant identifiers specified in the relevant protocols included in the LMF (e.g., TS29.572

[0033] ) can be used by the LMF to identify the target terminal location session.

[0107] In the above process, access network devices can participate in AI-based localization, and as described in scenario 3a above, the localization model can be deployed on the access network devices. In this case, the access network devices need to train the model based on samples, which mainly include terminal-related data collected by the LMF (e.g., ground truth labels, angles, speeds, etc.). The LMF can send the collected data to the access network devices during NRPPa interactions.

[0108] However, the problem is that, based on the traditional NRPPa process, the interaction is initiated by the LMF and cannot be initiated by the access network device. This results in the access network device not being able to obtain the data required for training the model in a timely manner.

[0109] Figure 2 is an interactive schematic diagram of an information sending method according to an embodiment of the present disclosure.

[0110] As shown in Figure 2, the information sending method may include the following steps:

[0111] In step S201, the core network device (e.g., LMF) sends the first information to the access network device.

[0112] In some embodiments, the access network device receives first information sent by the core network device.

[0113] For example, the first information can be NRPPa information, such as traditional NRPPa information or newly defined NRPPa information. The first information will be explained in subsequent embodiments.

[0114] In step S202, the access network device sends the second information to the core network device based on the first information.

[0115] In some embodiments, the second information includes a data collection request.

[0116] In some embodiments, a data collection request is used to request the core network device to send data to the access network device.

[0117] In some embodiments, the data requested by the data collection request is used by the access network device for model training.

[0118] It should be noted that the data requested in the data collection request can be used for other purposes besides model training, such as model monitoring (also known as model validation).

[0119] In some embodiments, the access network device can use the requested data as training samples, and then train the model based on the training samples to obtain a model for localization (e.g., for determining the location of the terminal). For example, the access network device can perform localization according to case 3a above based on the trained model.

[0120] According to embodiments of this disclosure, the access network device sends a second message to the core network device, requesting the core network device to send data for model training to the access network device, so that the access network device can obtain the data required for training the model in a timely manner, thereby improving the rate at which the access network device obtains the data required for training the model, so as to advance the time for the access network to train the model and improve the efficiency of model-based localization.

[0121] Furthermore, taking the aforementioned first and second information as examples of NRPPa interaction information, in this embodiment, the access network device can send the second information to the core network device after the core network device sends the first information, thereby ensuring that the requirement that NRPPa interaction is initiated by the core network device is met.

[0122] In some embodiments, the first information includes at least one of the following:

[0123] The first identifier of the interaction in which the first information is located, for example, the interaction can be an interaction initiated by the core network device through the first information, or it can be an interaction between the core network device and the access network device, such as a session, processing, service, etc.

[0124] Capability information, wherein the capability information is used to indicate the instructions of the core network equipment regarding data collection;

[0125] The core network device supports sending data to the access network device, which corresponds to the identifier of the terminal.

[0126] At least one identifier of available interactions, for example, which interactions are available, can be determined by the core network device and indicated to the access network device in the first information. The access network device can select and use interactions within the range of available interactions indicated by the core network device.

[0127] It should be noted that the content of the first information is not limited to the items mentioned above, and may also include other content, such as a first measurement identifier. The first measurement identifier is used to identify the measurement task of the positioning measurement. The measurement results obtained in the measurement task can be associated with the model training data received from the core network device, and used as the same dataset for model training. In the embodiments of this disclosure, the model training data received from the core network device can also be used for model monitoring.

[0128] For example, the identifier of a terminal can be represented in the form of a list of terminal identifiers. For example, the identifier of a terminal may include at least one of the following: NGAP (NG Application Protocol) terminal identifier, CGI (Cell Global Identity) + C-RNTI (Cell-Radio Network Temporary Identifier).

[0129] For example, core network equipment includes LMF, which can obtain NGAP terminal identifiers from AMF (Access and Mobility Management Function);

[0130] For example, core network equipment includes LMF, which can obtain CGI+C-RNTI from the terminal;

[0131] In some embodiments, the first information includes a first identifier of the interaction in which the first information is located, and the second information further includes the first identifier.

[0132] For example, the first identifier of an interaction (transaction) initiated by a core network device to an access network device by sending first information is transaction#1, and the first information may carry the first identifier of the interaction.

[0133] Based on the first identifier in the first information, the access network device can determine that the first identifier of the interaction in which the first information is located is transaction#1. Then, when sending the second information to the core network device, the first identifier transaction#1 can be carried in the second information. Accordingly, after the core network receives the second information, it can determine that the second information and the first information belong to the same interaction based on the first identifier therein, thereby avoiding errors in understanding the steps in different interactions.

[0134] In some embodiments, the first information includes at least one identifier of an available interaction, and the second information further includes a second identifier of the interaction, wherein the second identifier belongs to the identifier of the at least one available interaction.

[0135] The core network device can configure the range of available interactions for the access network device using first information, such as identifiers for at least one available interaction. The access network device can determine that the available interaction corresponds to the identifier of the available interaction. Therefore, when sending second information to the core network device subsequently, the selected interaction is the one corresponding to the identifier of the available interaction. This ensures the core network device's control over the access network device, and the access network device can select interactions within the range defined by the core network device, thus improving the communication flexibility of the access network device to a certain extent.

[0136] For example, the first information includes identifiers for three available interactions: transaction#1, transaction#2, and transaction#3. When the access network device sends the second information, it can select one interaction from these three identifiers. For example, if it selects the interaction corresponding to transaction#2, then the second information can carry a second identifier, such as transaction#2, so that the core network device can clearly identify the interaction to which the second information belongs.

[0137] In some embodiments, the first information includes a first measurement identifier corresponding to the first information, and the second information includes the first measurement identifier, for instructing the core network device to request data corresponding to the measurement identifier so that the access network device can associate the measurement results and data.

[0138] In some embodiments, sending the second information to the core network device based on the first information includes at least one of the following:

[0139] Response information to the first information is determined based on the first information, wherein the response information is the second information;

[0140] A second identifier for an interaction is determined from at least one identifier of an available interaction included in the first information, and second information is sent to the core network device based on the second identifier, wherein the second information further includes the second identifier, and the second identifier belongs to the identifier of the at least one available interaction.

[0141] For example, the first information includes a first identifier of the interaction in which the first information is located. The access network device can determine the response information to the first information based on the first information and use the response information as the second information. Since the second information is the response information to the first information and can belong to the same interaction as the first information, the first identifier can be carried in the second information so that the core network device can clearly identify that the second information and the first information belong to the same interaction.

[0142] For example, the first information includes an identifier for at least one available interaction. The access network device can determine that the available interaction corresponds to the identifier of the available interaction. Therefore, when sending the second information to the core network device subsequently, the selected interaction is the one corresponding to the identifier of the available interaction. This ensures the core network device's control over the access network device, and the access network device can select interactions within the scope limited by the core network device, thereby improving the communication flexibility of the access network device to a certain extent.

[0143] In some embodiments, the second information includes the data collection request.

[0144] In some embodiments, the data collection request includes data collection requirement information, wherein the data collection requirement information includes at least one of the following:

[0145] The measurement quantity corresponding to the data;

[0146] The number of terminals corresponding to the data;

[0147] The information in the data;

[0148] The time information for the core network to send data to the access network device;

[0149] The core network sends control information to the access network equipment to send data.

[0150] The first measurement identifier associated with the data.

[0151] In some embodiments, the first measurement identifier associated with the data is the first measurement identifier in the first information.

[0152] For example, the data collection request in the second information may include data collection requirement information, which may indicate the access network device's expectation that the core network device will collect data.

[0153] For example, the requirement information may include the measurement quantities corresponding to the data, such as angle, speed, and position.

[0154] For example, the demand information may include the number of terminals corresponding to the data, n. That is, the collected data may be obtained from measurements of n terminals, for example, n is a value greater than or equal to 1.

[0155] For example, the demand information may include time information such as the time when the core network sends data to the access network device, and the time information may include the start time, end time, duration, etc.

[0156] For example, the demand information may include control information for the core network to send data to the access network device, such as instructing the access network device to start sending data or instructing the access network device to stop sending data.

[0157] In some embodiments, the information in the data includes at least one of the following:

[0158] The data corresponds to the identifier of the terminal;

[0159] The time corresponding to the data collection.

[0160] For example, access network devices can indicate the identifier of a terminal as needed, and can collect data corresponding to the identifier of the terminal. For example, access network devices can determine the identifier of the terminal corresponding to the data based on historical information (such as terminals whose location information has been previously determined by the access network device).

[0161] For example, access network devices can indicate the time for data collection as needed. This time can be one or more time nodes, or one or more durations. For example, time nodes can be represented by timestamps, and durations can be represented by start and end times, or by start time and duration, where duration can be represented by period parameters, for example. For example, core network backup can send the data collected at this time to the access network devices.

[0162] In some embodiments, the information sending method further includes:

[0163] Send a third message to the core network device, wherein the third message is used to indicate at least one of the following:

[0164] Stop sending data to the access network device;

[0165] Update the data collection requirement information in the data collection request.

[0166] For example, after sending the second information, the access network device can send a third information to the core network device. This third information can be used to instruct the access network device to stop sending data to the core network device, or it can be used to update data collection requirements, such as updating the measurement quantities corresponding to the data, or updating the number of terminals corresponding to the data.

[0167] Accordingly, the traditional NRPPa interaction has been extended. The NRPPa interaction is no longer limited to ending when the core network device receives the second information sent by the access network device; the access network device can also send a third piece of information after sending the second. Furthermore, the third piece of information can instruct the core network device to stop sending data to the access network device and update the data collection requirement information in the data collection request, which helps ensure that the data collected by the core network device meets the needs of the access network device.

[0168] The technical solutions of this disclosure will be illustrated by several further embodiments below.

[0169] Figure 3 is an interactive schematic diagram illustrating another information sending method according to an embodiment of the present disclosure.

[0170] As shown in Figure 3, the first and second information can be traditional NRPPa information, such as the first information being a TRP information request and the second information being a TRP information response.

[0171] TRP (Transfer Request for Proxies) messages may carry capability information, which indicates the core network device's indication of whether it supports data collection. For example, the capability information may indicate whether the core network device supports data collection or not.

[0172] TRP message responses can carry data collection requests. For example, if an access network device determines that a core network device supports data collection based on capability information, it can include a data collection request in its TRP message response.

[0173] After receiving the TRP information response, the core network equipment can collect data according to the data collection request carried in it, and send the collected data to the access network equipment for model training and / or model monitoring.

[0174] In some embodiments, the core network device includes the collected data in the NRPPa measurement request message sent to the access network device, so that the access network device can associate the collected data with the results of the measurement requested in the measurement request and use them as the same dataset for model training and / or model monitoring.

[0175] The first information and the second information may carry an interaction identifier, and the interaction identifier carried by the first information and the second information may be the same.

[0176] In some embodiments, the first information is included in the NRRPa TRP information request message, and the second information is included in the NRRPa TRP information response message.

[0177] In some embodiments, if the first information is included in the NRPPa TRP information request message and the access network device has a data collection requirement, the access network device may include the second information in the NRPPa TRP information response message to request the core network device to provide data.

[0178] In some embodiments, the first information is included in the NRPPa measurement request message, and the second information is included in the NRPPa measurement response message and / or the NRPPa measurement report message.

[0179] In some embodiments, if the first information is included in the NRPPa TRP measurement request message, and the access network device wants to request data provided by the core network device associated with the measurement results requested in the measurement request, the access network device may include the second information in the NRPPa measurement response message and / or NRPPa measurement report message to request the core network device to provide data associated with the measurement. After obtaining the core network device data, it can use the measurement results requested in the measurement request as the same dataset for model training and / or model monitoring, thereby realizing the association between the measurement results collected by the access network device and the data provided by the core network.

[0180] In some embodiments, the core network device carries a first measurement identifier and / or a second identifier corresponding to the data while providing the data, for the access network device to associate the measurement result corresponding to the first measurement identifier with the data provided by the core network.

[0181] In some embodiments, the first measurement identifier may be an LMF measurement ID and / or a RAN measurement identifier.

[0182] Figure 4 is an interactive schematic diagram illustrating another information sending method according to an embodiment of the present disclosure.

[0183] As shown in Figure 4, the first, second, and third information can be newly defined NRPPa information. For example, the first information can be a data collection notification, which may carry capability information. This capability information indicates the core network device's indication of data collection. For example, the capability information indicates whether the core network device supports data collection or does not support data collection.

[0184] For example, the second information is a data collection request, which carries data collection requirement information, such as control information, such as initiating data transmission to the access network device.

[0185] In some embodiments, after sending the second information, the access network device may also send a third information. For example, the third information may be data collection update information, which may update the data collection requirement information in the data collection request, such as updating the control information to stop, so as to instruct the core network device to stop sending data to the access network device.

[0186] The first, second, and third information may carry an interaction identifier, and the interaction identifiers carried by the first and second information may be the same.

[0187] Figure 5 is an interactive schematic diagram illustrating another information sending method according to an embodiment of the present disclosure.

[0188] As shown in Figure 5, the first and second information can be traditional NRPPa information, such as the first information being a TRP information request and the second information being a TRP information response.

[0189] The first information may carry at least one identifier for an available interaction, such as from identifier x to identifier y. The first information may include a first identifier for the interaction, indicating that the interaction to which the first information belongs is the interaction corresponding to the first identifier.

[0190] When an access network device needs to collect data for model training, it can send a second message to the core network device, which carries a data collection request. Furthermore, the terminal can select a second identifier from identifiers x to y as the identifier for the interaction containing the second message.

[0191] Furthermore, the core network device can send a data collection response to the access network device. For example, the data collection response may include data from one or more terminals, and the data of each terminal includes one of the following attributes: terminal identifier, timestamp, and data of the terminal at the time corresponding to the timestamp (e.g., ground truth label info). In some embodiments, the data sent from the core network to the access network device is the actual location of the terminal device at a specific time, or a positioning measurement generated based on the actual location, such as angle of arrival or time difference of arrival.

[0192] The communication method involved in the embodiments of this disclosure may include at least one of steps S201 to S202. For example, step S201 may be implemented as a standalone embodiment, step S202 may be implemented as a standalone embodiment, and step S201+S202 may be implemented as a standalone embodiment, but is not limited thereto.

[0193] In some embodiments, steps S201 and S202 may be performed in an alternate order or simultaneously.

[0194] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0195] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0196] In some embodiments, other optional implementations described before or after the specification corresponding to FIG2 may be referred to.

[0197] In some embodiments, the data collection process initiated by the access network device can be based on one of the following three methods:

[0198] Method 1 (refer to Figure 3): Data collection initiated by LMF uses the TRP information exchange process to instruct LMF to support data collection, so that the access network device can indicate the data collection request in the TRP information feedback.

[0199] Method 2 (refer to Figure 4) introduces a new data collection process initiated by the LMF to support the complete data collection, update and stop process. The process may include: the LMF indicating support for data collection; the access network device responding that data collection is required; and the access network device being able to update or terminate data collection.

[0200] Method 3 (refer to Figure 5): Data collection initiated by the access network device. The LMF provides the base station with a range of transaction IDs that the base station can use. The access network device selects a transaction ID within the range to initiate the data collection service.

[0201] In some embodiments, the correlation between the data provided by the LMF and the measurements on the access network device side can be achieved based on one of the following three options:

[0202] Option 1: The access network device directly submits a data collection request to the LMF. The LMF selects UEs that meet the conditions and provides the base station with measurement configuration and measurement training data (information related to ground truth labels).

[0203] Option 2: The access network device determines the UEs that need to collect data based on historical measurement data, and indicates the UE ID and corresponding time to the LMF that the data needs to be requested. The LMF then provides training data to the base station based on the UE ID and time.

[0204] Option 3: The LMF notifies the access network device which UEs can provide data. The access network device selects the UE and provides the UE ID to the LMF, and obtains training data.

[0205] In some embodiments, the base station sends a data collection request to the LMF based on first information, and the LMF provides the requested data to the base station based on the data collection request, wherein the requested data is used for model training of the base station.

[0206] In some embodiments, the base station receives first information from the LMF, wherein the first information is used to indicate information on data collection supported by the LMF, and the first information includes at least one of the following:

[0207] The first identifier is used to indicate the transaction in this process, i.e., the transaction ID;

[0208] Data collection capability indication;

[0209] Supports a list of UE IDs for providing data; for example, the UE ID can be an NGAP UE ID or a CGI+C-RNTI; for example, the LMF can obtain the NGAP UE ID from the AMF; for example, the LMF can obtain the CGI+C-RNTI information from the UE.

[0210] Identification allocation information, used to indicate the Transaction ID range that the LMF assigns to the base station.

[0211] In some embodiments, the data request information includes at least one of the following:

[0212] The second identifier is used to indicate the transaction of this process, i.e., the transaction ID; for example, the second identifier is the same as the first identifier, i.e., it identifies that the first information and the data collection request information are in the same transaction; for example, the second identifier is selected by the base station based on the identifier allocation information.

[0213] Information regarding the requirements for data collection.

[0214] In some embodiments, the data collection requirements information includes at least one of the following:

[0215] The requested data measurement quantity;

[0217] Please specify the start and / or end times for data collection.

[0218] Request a start or end instruction for data collection;

[0219] Request UE information for data collection.

[0220] In some embodiments, the first information is included in the first message, the data collection request information is included in the second message, and the first message and the second message belong to the same transaction.

[0221] In some embodiments, the base station sends information to the LMF for updating data collection (stop or update request), which is included in a third message.

[0222] In some embodiments, first information is included in a first message, data collection request information is included in a second message, the first message and the second message belong to different transactions, and the transaction ID in the second message is determined based on the first information.

[0223] In some embodiments, the UE information requested for data collection includes information about one or more UEs, and the information about each UE includes at least one of the following:

[0224] UE identification information;

[0225] The time corresponding to data collection.

[0226] In some embodiments, the time corresponding to the data collection includes one or more time nodes. For example, it could be the timestamps of one or more requests; or, for example, it could be a start time and a period parameter.

[0227] In some embodiments, the UE identifier obtained by the LMF may be the NGAP UE ID and the AMF information of the serving UE. The LMF can determine the UE identifier corresponding to the NGAP UE ID through the AMF.
