Description

Positioning data collection method, communication device, electronic device and storage medium

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on February 8, 2024, with application number 2024101777730 and invention name “Positioning data acquisition method, communication device, electronic device and storage medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a positioning data acquisition method, a communication device, an electronic device, and a storage medium. Background Art

[0003] Positioning is one of the important applications of mobile communication networks such as 4G and 5G. By measuring and calculating the signals between the mobile network and the terminal device, the true location of the terminal device can be determined. In 5G and future communication networks, artificial intelligence (AI) / machine learning (ML) technologies can be used to locate terminal devices. Compared with traditional positioning methods that rely on line of sight (LoS) propagation, AI / ML positioning methods utilize data collection and analysis to improve positioning accuracy in non-line of sight (NLoS) propagation situations such as occlusion. Therefore, AI / ML positioning methods can provide more accurate positioning than traditional positioning methods in various complex environments such as factories, buildings, indoors, and outdoors.

[0004] AI / ML positioning methods use pre-trained AI / ML positioning models for positioning, and the generation of high-performance AI / ML positioning models relies on data. The collected data can be used for model training / retraining, model verification / monitoring, etc. For example, before using the AI / ML positioning method for positioning, it is necessary to collect positioning data as training samples. These positioning data are used as training samples to train the designed AI / ML positioning model; finally, the trained model is deployed for positioning. For another example, by collecting data, the previously trained model is retrained and updated to form a new model. For another example, by collecting data and using the model to process the data, the performance of the model can also be verified or monitored based on the results output by the model. As can be seen from the above, data collection is of great significance. Based on this, the present application provides a feasible solution for collecting positioning data. Summary of the Invention

[0036] In this application, "at least one" refers to one or more, and "plurality" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a alone, b alone, or c alone can represent: a alone, b alone, c alone, a and b in combination, a and c in combination, b and c in combination, or a, b, and c in combination, where a, b, and c can be single or multiple. In addition, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0037] Please refer to Figure 1. The existing mobile communication system includes: LMF101, TRP102, TRP103, TRP104 and terminal device 105. Figure 1 takes 3 TRPs as an example. It should be understood that more or fewer TRPs can be deployed in the mobile communication system, and are not limited to 3. Figure 1 is only an example and does not limit the architecture of the mobile communication system.

[0038] Among them, LMF101 is mainly responsible for selecting the positioning method and triggering positioning-related measurements, and can calculate the positioning results and accuracy. TRP102, TRP103, and TRP104 are mainly responsible for sending the downlink positioning reference signal (PRS) used for positioning and receiving the uplink reference signal from the terminal device 105, such as the uplink sounding reference signal (SRS) or the uplink positioning SRS. A base station can manage one or more TRPs. For example, in a 5G scenario, a 5G base station (such as a next-generation base station gNB) can control multiple TRPs. Positioning-related data can be transmitted between the LMF and the base station based on the New Radio Positioning Protocol (NRPPa), and positioning-related data can be transmitted between the terminal device 105 and LMF101 based on the LTE Positioning Protocol (LPP).

[0039] The terminal device 105 may be a wireless terminal. The wireless terminal may be a device that provides voice and / or other service data connectivity to a user, a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem. The wireless terminal may communicate with the LMF via a radio access network (RAN). The wireless terminal may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal. For example, the wireless terminal may be a portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile device that exchanges voice and / or data with the radio access network. For example, a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a drone, a wearable device, a terminal in the Internet of Vehicles, and the like. A wireless terminal may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, an access terminal, a user terminal, a user agent, a user device or user equipment, or a user equipment (UE), without limitation herein. Furthermore, the terminal device may use a mobile operating system such as iOS, Android, or Hongmeng, which is not limited in the embodiments of the present application.

[0040] The terminal device may also be a Positioning Reference Unit (PRU). From the perspective of the location server, a PRU is a device with a known location.

[0041] When implementing terminal device positioning in conjunction with the mobile communication system shown in Figure 1, positioning methods can be divided into two categories based on the different positioning reference signals:

[0042] One positioning method is: LMF101 configures one or more TRPs among TRP 102, TRP 103 and TRP 104 to send PRS, the terminal device 105 receives the downlink positioning reference signal (PRS) sent by one or more TRPs and obtains the corresponding measurement information, and uses the measurement information to calculate the positioning result of the terminal device 105.

[0043] Another positioning method is: the terminal device 105 sends SRS to one or more TRPs, the TRP obtains the corresponding measurement information, and reports the measurement information to LMF101, and LMF101 calculates the positioning result of the terminal device 105 based on the received measurement information.

[0044] In the above interaction process, LMF101 and the base station to which TRP belongs exchange positioning-related data through NRPPa, and LMF101 and the terminal device 105 exchange positioning-related data through the LPP protocol, thereby collaboratively completing the sending and measurement of positioning signals and obtaining the terminal device location.

[0045] The following introduces the two protocols NRPPa and LPP:

[0046] The LMF and the base station communicate via NRPPa, and the RAN device (e.g., gNB) configures one or more TRPs it manages for all or part of the following tasks: ① Measuring the uplink SRS sent by the terminal device; ② Reporting the measurement or other information to the LMF; ③ Configuring and sending the downlink PRS signal for each TRP; and ④ Exchanging other positioning-related data between the LMF and RAN devices.

[0047] The LMF and terminal devices can communicate via the LPP protocol. First, after measuring the downlink PRS signals sent by one or more TRPs, the terminal device can send the measurement values ​​and related information to the LMF via LPP. Second, the terminal device can send its positioning capabilities to the LMF via LPP. Third, the LMF can provide positioning assistance information to the terminal device via LPP.

[0048] This application mainly communicates through LMF and wireless access network equipment, and the terminal equipment cooperates to complete the positioning data collection. For greater clarity, the relationship between NRPPa and wireless access network equipment and LMF is first introduced here.

[0049] Figure 2 illustrates the relationship between NRPPa, gNB, and TRP when the radio access network device is a gNB. The right side of Figure 2 shows the protocol stacks of the gNB, AMF, and LMF. The LMF protocol stack, from top to bottom, consists of: NRPPa, Hypertext Transfer Protocol (HTTP) / 2, Transport Layer Security (TLS), Transmission Control Protocol (TCP), Internet Protocol (IP), Layer 2, and Layer 1. The LMF-facing protocol stack in the Access and Mobility Management Function (AMF), from top to bottom, consists of: HTTP / 2, TLS, TCP, IP, Layer 2, and Layer 1. The gNB-facing protocol stack in the AMF, from top to bottom, consists of: Next Generation Access Protocol (NGAP), Scalable TCP (STCP), IP, Layer 2, and Layer 1. The gNB protocol stack, from top to bottom, consists of: NRPPa, NGAP, STCP, IP, Layer 2, and Layer 1. The various layers of the gNB protocol stack interact with the AMF through the NG-C interface, and the various layers of the AMF protocol stack interact with the LMF through the NL1 interface. STCP is a TCP congestion control protocol. L1 is the physical layer, and L2 is the Media Access Control (MAC) / Radio Link Control (RLC) protocol.

[0050] The gNB is divided into two parts according to the protocol: the Central Control Unit (CU) and the Distributed Unit (DU). A gNB can include multiple DUs, each of which can manage one or more TRPs. Figure 2 shows that each DU manages n TRPs, TRP_1 to TRP_n, where n is a positive integer greater than 1. The gNB's CU receives and sends data over the NG-C interface. The CU and DU interact over the F1-C interface. The DU uses the TRPs it manages to send data over the NR-Uu interface.

[0051] In combination with the foregoing, the positioning data collected in this application can be used for model training or retraining, verification or monitoring.

[0052] Figure 3 illustrates a scenario for collecting positioning data for model training. The terminal device sends an SRS, and the TRPs under gNB_1 to gNB_n receive the SRS and calculate measurement information. gNB_1 to gNB_n then send this measurement information to the LMF via NRPPa. The LMF can also obtain the terminal device's positioning results through other mechanisms, bind the positioning results to the measurement information as a label, and perform other processing before using them for model training.

[0053] Using positioning methods involving uplink reference signals, such as uplink time difference of arrival (UL-Time Difference of Arrival, TDOA), uplink-angle of arrival ranging (UL-AoA), and multiple round-trip time (Multi-RTT), these positioning methods will use the same NRPPa basic process or steps to enable LMF to obtain measurement information based on uplink reference signals. The following example shows how LMF obtains measurement information of uplink reference signals in existing mobile communication systems through the embodiment shown in Figure 4. The embodiment shown in Figure 4 is a flow chart of the existing UL-TDOA positioning method. Please refer to Figure 4, which includes the following steps:

[0054] S40: Exchange configuration information of each TRP based on NRPPa, so that LMF can obtain configuration information of each TRP.

[0055] S41: Transmit positioning capability based on LPP, so that LMF can learn the positioning capability of the terminal device.

[0056] S42. The LMF sends an NRPPa-based positioning information request message (NRPPa positioning information request) to the serving gNB. The NRPPa-based positioning information request message is used to request the serving gNB to configure the SRS for the UE. In addition, the positioning information request message carries a measurement-related configuration request, specifically including: the identifier of the TRP participating in the measurement and measurement parameter information. The identifier of the TRP participating in the measurement indicates the LMF's configuration request for the TRP used in the measurement; the measurement parameter information indicates the LMF's configuration request for the measurement mode expected to participate in the measurement.

[0057] S43. The serving gNB determines the uplink reference signal configuration of the terminal device.

[0058] S43a, the serving gNB configures uplink reference signals for the terminal device.

[0059] S44. The serving gNB sends an NRPPa-based positioning information response message to the LMF. The NRPPa-based positioning information response message is used to send the actual SRS configuration of the UE to the LMF.

[0060] Next, the uplink reference signal transmission of the terminal device is activated through S45a to S45c.

[0061] S45a. The LMF sends an NRPPa-based positioning activation request message (NRPPa positioning activation request) to the serving gNB. The purpose of the positioning activation request message is to instruct the serving gNB to notify the terminal device to activate uplink reference signal transmission.

[0062] S45b. The serving gNB notifies the terminal device to activate uplink reference signal transmission.

[0063] S45c: The serving gNB sends an NRPPa-based positioning activation response message (NRPPa positioning activation response) to the LMF. The positioning activation response message is used to respond to the positioning activation request message.

[0064] S46. The LMF sends an NRPPa measurement request message to each gNB. The measurement request message is used to request each gNB to perform measurements, and the measurement request message includes the actual uplink reference signal configuration of the terminal device.

[0065] The LMF sends a measurement request message based on NRPPa to the serving gNB and the Neighbor gNB.

[0066] The actual SRS configuration of the terminal device includes information about the data collection mode. The data collection mode can be OnDemand or periodic. OnDemand means that the data collection mode is once, and periodic means that the data collection mode is periodic.

[0067] S47. Each gNB performs uplink reference signal measurement.

[0068] S48. Each gNB sends an NRPPa measurement response message / measurement report to each LMF. The measurement response message / measurement report carries measurement information for each TRP under the gNB.

[0069] If the data collection mode indicated by S46 is OnDemand, the gNB sends the measurement information to the LMF through a Measurement Response message. If the data collection mode indicated by S46 is Periodic, the gNB sends the measurement information to the LMF through a Measurement Report.

[0070] S49. LMF sends an NRPPa-based positioning deactivation request message (NRPPa positioning deactivation request) to each gNB.

[0071] Analyzing the embodiment shown in FIG4 , the existing method for LMF to obtain SRS measurement information has the following problems:

[0072] 1. Current measurement-related configuration requests for TRPs will cause resource waste

[0073] As shown in Figure 4, in existing positioning methods, the NRPPa positioning information response at S44 carries a measurement configuration request, specifically including the TRP identifier and measurement parameter information. The LMF only indicates the TRP identifier, meaning that the measurement must include resources within all resource sets within the TRP. However, positioning model training / retraining / validation / monitoring may require measurement information for only some resources within a subset of the TRP's resource sets. The existing granularity of TRP-related parameter indications results in unnecessary measurements, wasting resources.

[0074] 2. The current NRPPa supports limited measurement information and cannot meet the needs of positioning model training / retraining / verification / monitoring.

[0075] When using a positioning model for positioning, the corresponding measurement information needs to be input into the positioning model. For example, in a positioning scenario using the UE's uplink SRS, each TRP receives the SRS sent by the UE, and then obtains the CIR / PDP / DP measurement information based on the SRS. This measurement information is then used as input data for the positioning model and transmitted to the location of the positioning model. If the positioning model is deployed in the LMF, the CIR / PDP / DP measurement information needs to be transmitted from the gNB to the LMF via NRPPa. The LMF then uses the CIR / PDP / DP measurement information as input data for the positioning model.

[0076] However, the existing NRPPa protocol does not currently support CIR / PDP / DP measurements. The measurements indicated by the LMF to the gNB do not include CIR / PDP / DP measurements. This prevents the LMF from obtaining the required CIR / PDP / DP measurement information, which in turn makes NRPPa unable to meet the requirements of positioning model training / retraining / validation / monitoring. Therefore, NRPPa needs to add new measurement information for AI / ML positioning methods.

[0077] 3. Before data collection starts, LMF cannot know whether the gNB / TRP participating in data collection supports all types of measurement information to be collected

[0078] This problem can also be understood as the LMF cannot know the support status of the measurement-related configuration requests of each gNB / TRP participating in data collection before data collection starts.

[0079] In traditional positioning methods for real-time positioning, NRPPa supports the gNB to send measurement information of multiple measurements to the LMF. However, since the purpose of the gNB sending measurement information of multiple measurements to the LMF is to calculate the UE position in real time, for the sake of real-time positioning, the signaling carrying measurement information (such as the NRPPa measurement response or measurement report in Figure 4) is not used to carry a large amount of measurement information.

[0080] Data collection for scenarios such as positioning model training / retraining / validation / monitoring involves the collection of large amounts of data from multiple gNBs / TRPs. Specifically, multiple gNBs are required to simultaneously collect and upload large amounts of various measurement information. For example, each gNB is required to simultaneously upload measurement information for each TRP of different measurement types (such as CIR, PDP, DP), different measurement modes, and different formats. Therefore, the volume of measurement information required for model training / retraining / validation / monitoring may be greater than that of traditional measurement data reporting, and the real-time requirements for data collection may not necessarily be as high (for example, during offline training, the real-time requirements for data collection are lower).

[0081] Therefore, new signaling processes are required to support model-oriented data collection, the simultaneous collection of large volumes of data from multiple gNBs / TRPs, and various types of data. Furthermore, before data collection begins, the LMF must communicate through signaling whether each gNB / TRP supports the relevant measurements. Based on the information returned by the gNB, the LMF can adjust or reconfigure parameters such as data type and format before data collection begins.

[0082] 4. Existing positioning methods do not support LMF requests for specific SRS configurations for data collection

[0083] As shown in Figure 4 , in existing positioning methods, the NRPPa positioning information response at step S44 carries the UE's actual SRS configuration. This means that existing positioning methods currently only support the serving gNB notifying the LMF of the current UE's SRS configuration, and do not support the LMF directly specifying the UE's SRS configuration.

[0084] However, when the LMF needs to collect positioning data for training / retraining / validation / monitoring positioning models, it may be necessary for the LMF to collect measurement information under a specific SRS configuration. Therefore, the LMF needs to configure a specific SRS to the gNB through the NRPPa protocol. However, the current NRPPa protocol does not support the LMF's ability to configure a specific SRS, and cannot meet the LMF's need to collect measurement information for a specific SRS configuration.

[0085] 5.LMF needs to synchronize the start / stop of data collection for each gNB / TRP

[0086] Data collection for model training involves multi-gNB collaboration. That is, the data collected by each gNB / TRP must be temporally correlated. For example, it is important to avoid situations where the first set of data reported by gNB1 corresponds to the UE's SRS measurement at time T1, while the first set of data reported by gNB2 corresponds to the UE's SRS measurement at time T2, and the first set of data reported by gNBn corresponds to the UE's SRS measurement at time Tn. These situations may require additional data cleaning after reporting, resulting in wasted LMF resources. Therefore, a new signaling process is required to synchronize the activation and deactivation of data collection across multiple gNBs, thereby reducing LMF resource waste.

[0087] Next, some embodiments and drawings are used to describe in detail how this application solves the problems existing in the above-mentioned NRPPa and realizes positioning data collection. It should be noted that the "target terminal device" in this application can be any of the aforementioned wireless terminals or PRUs, and the subsequent description will not be repeated. In addition, the aforementioned Figures 1 to 4 are all illustrated by taking the deployment of TRP under the base station as an example. With the rapid development of wireless technology, TRP may also be deployed in any other type of wireless access network equipment, and the method of this application is also applicable.

[0088] FIG5 is a flow chart of a positioning data collection method provided in an embodiment of the present application. Referring to FIG5 , the method of this embodiment includes:

[0089] S51. The LMF sends first information to a radio access network device participating in positioning data collection, the first information including: a first uplink reference signal configuration, parameter information of a first TRP, and parameter information of a first measurement. Correspondingly, the radio access network device receives the first information.

[0090] It should be noted that before S51, LMF and each wireless access network device involved in positioning data collection communicate through NRPPa. LMF has obtained the TRP configuration information of each wireless access network device involved in positioning data collection, LMF has obtained the positioning capability of the target terminal device, and the first wireless access network device has completed the uplink reference signal configuration for the target terminal device.

[0091] The first radio access network device is one of the radio access network devices participating in positioning data collection, and is capable of performing uplink reference signal configuration for the target terminal device. The first radio access network device may participate in the uplink reference signal configuration of the target terminal device, but not participate in uplink channel measurement and transmission of measurement data. Alternatively, the first radio access network device may participate in both the uplink reference signal configuration of the target terminal device and the uplink channel measurement and data transmission. Alternatively, the first radio access network device may participate in the uplink reference signal configuration and uplink channel measurement of the target terminal device, but not participate in transmission of measurement data. The following embodiments of the present application are exemplified by the example that the first radio access network device may participate in the uplink reference signal configuration of the target terminal device and also participate in uplink channel measurement and data transmission.

[0092] It should be noted that the target terminal device can be any of the above-mentioned wireless terminals or PRUs, and is a terminal device that participates in the collection of positioning data.

[0093] The first uplink reference signal configuration is the uplink reference signal configuration used by the target terminal device for positioning, and is also the actual uplink reference signal configuration of the UE. The first uplink reference signal configuration may include configuration information of one or more uplink reference signals used for positioning. In this application, the uplink reference signal used for positioning may be an SRS or a positioning SRS.

[0094] As shown in Figure 4, when a large number of gNBs are participating in positioning, the serving gNB configures the uplink reference signal for the target terminal device, and other gNBs participating in positioning are unaware of the target terminal device's actual uplink reference signal configuration. Therefore, the LMF notifies all RAN devices participating in positioning data collection of the target terminal device's actual first uplink reference signal configuration for positioning, enabling all participating RAN devices to perform accurate measurements on the time-frequency resources containing the first uplink reference signal.

[0095] The parameter information of the first TRP is used to indicate that the LMF expects to participate in the TRP-related configuration request for uplink channel measurement. The parameter information of the first TRP includes: the identifier of the first TRP, the identifier of the target resource set under the first TRP and / or the identifier of the target resource under the first TRP.

[0096] A TRP can manage one or more resource sets, each of which can include multiple resources, with one resource corresponding to one beam. These resource sets and resources are each configured with corresponding identifiers, and resources contained in different resource sets can use the same identifier. LMFs and wireless access network devices can identify a resource, or a beam, using the "resource set identifier + resource identifier."

[0097] The identifier of the first TRP may be the ID of the first TRP. The identifier of the target resource set may be the ID of the target resource set. The identifier of the target resource may be the ID of the target resource.

[0098] In some embodiments, the parameters of the first TRP include an identifier of the first TRP and an identifier of the target resource set under the first TRP. In this way, the wireless access network device can determine that the resources that the LMF expects to participate in the uplink channel measurement include all resources in the target resource set of the first TRP by combining the identifier of the TRP indicated by the LMF and the identifier of the resource set. For example, if the identifier of the first TRP is TRP_1 and the identifier of the target resource set is resource set_1, then the resources that the LMF expects to participate in the uplink channel measurement include all resources contained in resource set_1 of TRP_1.

[0099] In some other embodiments, the parameters of the first TRP include an identifier of the first TRP, an identifier of the target resource set under the first TRP, and an identifier of the target resource. In this way, the wireless access network device can determine which specific resources in the target resource set of the first TRP that the LMF expects to participate in the uplink channel measurement by combining the identifier of the TRP, the identifier of the resource set, and the resource identifier indicated by the LMF. For example, if the identifier of the first TRP is TRP_1, the identifier of the target resource set is resource set_1, and the identifier of the target resource is resource_1, then the resources that the LMF expects to participate in the uplink channel measurement include resource_1 contained in resource set_1 of TRP_1.

[0100] In some other embodiments, the parameters of the first TRP include an identifier of the first TRP and an identifier of the target resource. By combining the identifier of the first TRP and the identifier of the target resource, it is possible to determine which resources the LMF expects to participate in the uplink channel measurement.

[0101] Exemplarily, the resources that the LMF expects to participate in the uplink channel measurement include the resources that match the identifier of the target resource in all resource sets under the first TRP. For example, the identifiers of the first TRP include TRP_1 and TRP_2, the identifier of the target resource is resource_1, TRP_1 includes resource set_1 and resource set_2, a total of two resource sets, and TRP_2 includes resource set_1 and resource set_2, a total of two resource sets. Then, the resources that the LMF expects to participate in the uplink channel measurement include: resource_1 in resource set_1 under TRP_1, resource_1 in resource set_2 under TRP_1, resource_1 in resource set_1 under TRP_2, and resource_1 in resource set_2 under TRP_2.

[0102] For example, when the LMF does not indicate a resource set, the wireless access network device can uniquely identify a target resource by combining the TRP identifier indicated by the LMF and the resource identifier. The target resource belongs to the resource that the LMF expects to participate in the uplink channel measurement.

[0103] The parameter information of the first measurement indicates that the LMF expects to participate in the measurement mode configuration request of the uplink channel measurement. The parameter information of the first measurement may include: one or more of the following information: measurement type, one or more measurement forms under the measurement type, positioning data collection form, measurement period, and search window information.

[0104] The measurement type may include uplink reference signal measurements used by any existing positioning method. Different measurement types may have requirements for parameters such as data length and resolution. Therefore, LMF indicates the measurement type, which is equivalent to indicating the corresponding data length, resolution and other parameter requirements of the radio access network device. For example, the CIR data length can be 64 / 128 / 256 units. LMF instructs the radio access network device to perform CIR measurement, which is equivalent to simultaneously instructing the radio access network device that the data length corresponding to the CIR measurement includes 64 / 128 / 256 units.

[0105] Among them, one or more measurement forms under the measurement type indicate specific measurement items. For example, CIR supports multiple forms of measurement. LMF specifically indicates that the measurement type is CIR and the measurement form is CIR form 1. In this way, the wireless access network device does not need to perform other forms of measurement under CIR.

[0106] The data collection modes include OnDemand and Periodic. OnDemand means collecting measurement information once, while Periodic means collecting measurement information periodically. The data collection mode of the first measurement can be configured as either mode.

[0107] The number of collection cycles indicates the number of measurements. If the data collection mode is OnDemand, the number of measurements is 1. If the data collection mode is Periodic, set the number of data collection cycles based on actual needs.

[0108] The search window information is used to provide auxiliary information for uplink reference signal detection. Each first TRP has a search window information. The search window information can be used to indicate: the expected transmission delay; the uncertainty or error in the expected transmission delay.

[0109] S52: The wireless access network device performs positioning data collection configuration based on the first information.

[0110] The wireless access network device configures the second TRP and the resource set and resources under the second TRP for the second measurement based on the parameter information of the first TRP, the parameter information of the first measurement, and the support for measurement by the TRP managed by the wireless access network device, so as to meet the measurement-related configuration request of the LMF as much as possible.

[0111] It should be understood that the second TRP is the TRP actually configured by the wireless access network device for positioning, and the second TRP includes all or part of the first TRP. The resource set and resources under the second TRP support the second measurement, and the second measurement includes all or part of the first measurement.

[0112] S53. The second TRP under each radio access network device performs a second measurement on the uplink reference signal sent by the target terminal device based on the first uplink reference signal configuration to obtain measurement data.

[0113] The measurement data includes measurement information obtained by the second TRP performing a second measurement on the uplink reference signal sent by the target terminal device.

[0114] For example, the second measurement includes four measurements: CIR, PDP, DP, and RSRP. The second TRP includes resource_1 included in resource set_1 under TRP1 managed by gNB1 and resource_1 included in resource set_1 under TRP1 managed by gNB2. In this way, resource_1 included in resource set_1 under TRP1 managed by gNB1 performs CIR, PDP, DP, and RSRP measurements on the uplink reference signal sent by the target terminal device, respectively, to obtain CIR measurement information 1, PDP measurement information 1, DP measurement information 1, and RSRP measurement information 1. Similarly, resource_1 included in resource set_1 under TRP1 managed by gNB2 performs CIR, PDP, DP, and RSRP measurements on the uplink reference signal sent by the target terminal device, respectively, to obtain CIR measurement information 2, PDP measurement information 2, DP measurement information 2, and RSRP measurement information 2. The measurement data sent by gNB1 to LMF includes CIR measurement information 1, PDP measurement information 1, DP measurement information 1, and RSRP measurement information 1; the measurement data sent by gNB1 to LMF includes CIR measurement information 2, PDP measurement information 2, DP measurement information 2, and RSRP measurement information 2.

[0115] S54: The wireless access network devices participating in the positioning data collection send measurement data to the LMF. Correspondingly, the LMF receives the measurement data sent by each wireless access network device.

[0116] S55. LMF generates positioning data for one or more first models based on the received measurement data, where the one or more first models are artificial intelligence models / machine learning models for positioning.

[0117] In some embodiments, the target terminal device (e.g., PRU) can determine its own location, and the LMF can obtain the PRU location through a pre-set communication mechanism. The LMF binds the known PRU location as tag information to the measurement data, and then forms positioning data for one or more first models after data cleaning.

[0118] The first model can be an artificial intelligence model / machine learning model used to locate the target terminal device, or an artificial intelligence model / machine learning model used for other devices. When there are multiple first models, the multiple first models can be positioning models used for the same device in different scenarios, or positioning models for different devices. The structures and model parameters of the multiple first models can be different, and this application does not limit this.

[0119] In the method of this embodiment, LMF indicates the resource set and / or resources under TRP participating in positioning data collection to the wireless access network device. Compared with the traditional positioning method, the TRP-related configuration request indicated by LMF in this solution to the gNB participating in positioning data collection has a finer granularity, thereby solving the problem that the measurement-related configuration request indicated by the traditional NRPPa protocol will cause waste of resources under TRP, that is, solving the aforementioned problem 1.

[0120] In the embodiment shown in Figure 5, the LMF and each radio access network device can communicate through a newly added signaling process based on NRPPa, or can also communicate using the existing interaction process of NRPPa to achieve positioning data collection. Next, Figure 6 shows a specific implementation method for implementing positioning data collection using the newly added signaling process, and Figure 7 shows a specific implementation method for implementing positioning data collection using the existing interaction process of NRPPa.

[0121] FIG6 is a flow chart of a positioning data collection method provided by another embodiment of the present application. Referring to FIG6 , the method of this embodiment includes:

[0122] S60: LMF and each radio access network device involved in positioning data collection exchange TRP configuration information based on NRPPa, so that LMF can obtain TRP configuration information of each radio access network device involved in positioning data collection.

[0123] S61: Based on the LPP capability transmission, the LMF obtains the positioning capability of the target terminal device.

[0124] S62. LMF sends a positioning information request message based on NRPPa to the first radio access network device.

[0125] The first radio access network device is equivalent to the serving gNB in ​​the embodiment of Figure 4, and is used to configure an uplink reference signal for the target terminal device and activate the uplink reference signal sending of the target terminal device.

[0126] S63. The first radio access network device determines a first uplink reference signal configuration of the target terminal device.

[0127] S63a: The first radio access network device configures a first uplink reference signal for the UE.

[0128] S64: The first radio access network device sends an NRPPa-based positioning information response message (NRPPa positioning information response) to the LMF, wherein the NRPPa-based positioning information response message is used to send the actual first uplink reference signal configuration of the UE to the LMF.

[0129] Next, the uplink reference signal transmission of the target terminal device is activated through S65a to S65c.

[0130] S65a. The LMF sends an NRPPa-based positioning activation request message (NRPPa positioning activation request) to the first radio access network device.

[0131] S65b. The first radio access network device notifies the target terminal device to activate uplink reference signal transmission.

[0132] S65c. The first radio access network device sends an NRPPa-based positioning activation response message (NRPPa positioning activation response) to the LMF.

[0133] The specific implementation process of S60 to S65c follows the method defined in the NRPPa protocol and will not be repeated here.

[0134] S66. LMF sends a first customized request message based on NRPPa to all first radio access network devices participating in positioning data collection, where the first customized request message carries the first information.

[0135] The first customized request message may be called an NRPPa-based data collection measurement configuration request message (NRPPa data collection measurement config request). In this way, the LMF may send the first information to all radio access network devices participating in data collection via the first customized request message, instead of sending the measurement request message (NRPPa measurement request) defined in the existing NRPPa.

[0136] S67. Each wireless access network device participating in positioning data collection performs positioning data collection configuration based on the first information.

[0137] S68a. The LMF sends an NRPPa-based positioning activation request message (NRPPa positioning activation request) to the first radio access network device.

[0138] S68b. The first radio access network device notifies the target terminal device to activate uplink reference signal transmission.

[0139] S68c. The first radio access network device sends an NRPPa-based positioning activation response message (NRPPa positioning activation response) to the LMF.

[0140] This embodiment shows that uplink reference signal transmission of the target terminal device is activated through S65a to S65c before S66, that is, S65a to S65c correspond to activation timing 1. In other embodiments, uplink reference signal transmission of the target terminal device can be activated through S68a to S68c after S66, that is, S68a to S68c correspond to activation timing 2. In actual applications, any timing can be selected for activation.

[0141] S69. The second TRP under each wireless access network device participating in positioning data collection performs a second measurement on the uplink signal sent by the target terminal device based on the first uplink reference signal configuration.

[0142] S610: Each wireless access network device participating in positioning data collection sends measurement data to the LMF.

[0143] S69 and S610 in this embodiment are similar to S53 and S54 shown in FIG5 , and reference may be made to the detailed description of the embodiment shown in FIG5 , which will not be repeated here.

[0144] S611. LMF generates positioning data for one or more first models based on the received measurement data, where the one or more first models are artificial intelligence models / machine learning models used for positioning.

[0145] S612: The LMF sends a positioning deactivation message to all radio access network devices participating in positioning data collection. In response, the radio access network devices receive the positioning deactivation message and, in response, disable the positioning-related configuration of the uplink reference signal. S612 terminates the positioning process, meaning positioning data collection is complete.

[0146] The method of this embodiment, by adding a new NRPPa message, indicates a finer-grained TRP-related configuration request to each wireless access network device involved in positioning data collection, thereby solving the problem that the measurement-related configuration request indicated by the traditional NRPPa protocol will cause resource waste under TRP, that is, it solves the aforementioned problem 1 and realizes positioning data collection.

[0147] In addition, in the embodiment shown in FIG6 , all first measurements indicated by the LMF to each radio access network device may include one or more measurements of CIR, PDP, DP, RSRP, RSRRP, RSTD, and RTOA.

[0148] Currently, NRPPa does not support CIR, PDP, and DP measurements. The optional range of the first measurement is different. The method shown in Figure 6 adds three new measurements of CIR, PDP, and DP for positioning data collection, and NRPPa can transmit measurement data of CIR, PDP, and DP for training / retraining / monitoring / verification of the first model to meet the model's measurement data requirements for more measurements.

[0149] FIG7 is a flow chart of a positioning data collection method provided by another embodiment of the present application. Referring to FIG7 , the method of this embodiment includes:

[0150] S70: The LMF and each radio access network device involved in positioning data collection exchange TRP configuration information based on NRPPa, so that the LMF can obtain TRP configuration information of each radio access network device.

[0151] S71: Based on the LPP capability transmission, the LMF obtains the positioning capability of the target terminal device.

[0152] S72. LMF sends a positioning information request message based on NRPPa to the first radio access network device.

[0153] S73. The first radio access network device determines a first uplink reference signal configuration of the target terminal device.

[0154] S73a: The first radio access network device configures a first uplink reference signal for the UE.

[0155] S74. The first radio access network device sends an NRPPa-based positioning information response message (NRPPa positioning information response) to the LMF. The NRPPa-based positioning information response message is used to send the actual SRS configuration of the UE to the LMF.

[0156] Next, the uplink reference signal transmission of the target terminal device is activated through S75a to S75c.

[0157] S75a. The LMF sends an NRPPa-based positioning activation request message (NRPPa positioning activation request) to the first radio access network device.

[0158] S75b. The first radio access network device notifies the target terminal device to activate uplink reference signal transmission.

[0159] S75c. The first radio access network device sends an NRPPa-based positioning activation response message (NRPPa positioning activation response) to the LMF.

[0160] The specific implementation process of S70 to S75c follows the method defined in the NRPPa protocol and will not be repeated here.

[0161] S76. The LMF sends a measurement request message (NRPPa measurement request) to each radio access network device participating in positioning data collection. The measurement request message carries the first information.

[0162] S77. Each wireless access network device participating in positioning data collection performs positioning data collection configuration based on the first information.

[0163] S78. The second TRP under each wireless access network device participating in positioning data collection performs a second measurement on the uplink signal sent by the target terminal device based on the first uplink reference signal configuration.

[0164] S79. Each radio access network device participating in positioning data collection sends measurement data to the LMF via a measurement report or a measurement response message.

[0165] S78 and S79 in this embodiment are similar to S53 and S54 shown in FIG5 , and reference may be made to the detailed description of the embodiment shown in FIG5 , which will not be repeated here.

[0166] S710. LMF generates positioning data for one or more first models based on the received measurement data, where the one or more first models are artificial intelligence models / machine learning models used for positioning.

[0167] S711: The LMF sends a positioning deactivation message to all radio access network devices participating in positioning data collection to disable the positioning-related configuration of the uplink reference signal. S711 indicates the end of the positioning process, that is, the completion of positioning data collection.

[0168] This embodiment adds a new information element in the measurement request message, and uses the new information element to indicate a finer-grained TRP-related configuration request to each wireless access network device involved in positioning data collection, thereby not changing the existing process. It solves the problem that the measurement-related configuration request indicated by the traditional NRPPa protocol will cause resource waste under TRP, that is, it solves the aforementioned problem 1 and realizes positioning data collection.

[0169] In addition, in the embodiment shown in FIG7 , all first measurements indicated by the LMF to each radio access network device may include one or more measurements of RSRP, RSRRP, RSTD, and RTOA.

[0170] After the LMF sends the first information to each radio access network device participating in the positioning data collection, the radio access network device may also provide feedback to the LMF on its support status for the measurement-related configuration request indicated by the LMF.

[0171] Based on the embodiment shown in FIG6 , optionally, after S66 , the following steps are further included:

[0172] S67a. Each radio access network device participating in positioning data collection sends second information to the LMF, where the second information indicates a support status of the radio access network device for the measurement-related configuration request in the first information.

[0173] In some embodiments, the radio access network device may send a first customized response message (NRPPa data collection measurement config response) based on NRPPa to the LMF, where the first customized response message carries the second information. The first customized response message is used to respond to the first customized request message.

[0174] In combination with Figures 6 and 7, the purpose of the wireless access network device sending the second information to the LMF is that the wireless access network device is mainly used to feedback to the LMF the overall support of the wireless access network device for measurement-related configuration requests, the overall support of each TRP for the first uplink reference signal configuration, and the support of each TRP for the first uplink reference signal configuration.

[0175] In some embodiments, the second information may include the following information content: whether the wireless access network device fully supports, partially supports, does not support, or indicates an error for the measurement-related configuration request in the first information, the identifier of the first TRP, whether the first TRP fully supports, partially supports, does not support, or indicates an error for the measurement-related configuration request indicated by the first information, and whether the target resource set or target resource indicated by the parameter information of the first TRP supports the first measurement.

[0176] The overall support status of the wireless access network device for the measurement-related configuration request can be represented by a bitmap or enumeration. For example, the options include: full support, partial support, no support, and error indication. In this way, the wireless access network device can feedback its full support, partial support, no support, or error indication for the measurement-related configuration request in the first information.

[0177] The identifier of the first TRP is used to indicate the TRP's support for the first uplink reference signal configuration and for which first TRP the TRP's support for the first uplink reference signal configuration is directed.

[0178] The overall support status of the first TRP for the first uplink reference signal configuration can be represented by a bitmap or enumeration. For example, the options include: full support, partial support, no support, and error indication. In this way, the wireless access network device can feedback that the first TRP fully supports, partially supports, does not support, or indicates an error for the measurement-related configuration request in the first information.

[0179] The support status of TRP for the first uplink reference signal configuration can be represented in the form of a bitmap or enumeration. For example, the options include: support, not support. In this way, the wireless access network device can provide feedback on whether the first TRP supports the first uplink reference signal configuration.

[0180] In the method of the embodiment shown in Figure 6 and the method of the embodiment shown in Figure 7, the radio access network device provides feedback to the LMF on its support for measurement-related configuration requests, allowing the LMF to know whether each radio access network device or TRP supports the required types of first measurements before initiating positioning data collection. On the one hand, this can provide a basis for the LMF to adjust the measurement-related configuration before initiating positioning data collection; on the other hand, if the LMF does not adjust the measurement-related configuration, the second information fed back by the radio access network device also provides a basis for the LMF to process the measurement data.

[0181] Referring to the introduction of the aforementioned embodiment, after the LMF obtains the TRP configuration information of each radio access network device participating in positioning data collection and the positioning capability of the target terminal device, it is necessary to configure the uplink reference signal for the target terminal device. However, the uplink reference signal configuration of the target terminal device in the traditional positioning method is determined by the radio access network device, and does not support the LMF requesting a specific SRS configuration for data collection. Next, the embodiments shown in Figures 8 and 9 will be used to describe in detail how this application solves the above problems.

[0182] FIG8 is a flow chart of a positioning data collection method provided by another embodiment of the present application. Referring to FIG8 , the method of this embodiment includes:

[0183] S81. The LMF sends a second customized request message to a first radio access network device. The second customized request message carries third information, where the third information is used to request the first radio access network device to configure an uplink reference signal for a target terminal device based on a second uplink reference signal configuration desired by the LMF. Accordingly, each radio access network device receives the second customized request message.

[0184] The second uplink reference signal configuration carried in the third information is the uplink reference signal configuration in which the LMF expects to participate in uplink channel measurement, and is used to indicate that the LMF expects the radio access network device to perform subsequent positioning data collection based on the second uplink reference signal configuration. Exemplarily, the third information may be carried in an information element named "required SRS config" in the second custom request message. It should be understood that the information element carrying the third information may also have other names.

[0185] The second uplink reference signal configuration may include configuration information of at least one uplink reference signal. The configuration information of each uplink reference signal includes: characteristic parameter configuration of the uplink reference signal in the time domain and frequency domain, an identifier of the physical serving cell of the uplink reference signal, a purpose of configuring the uplink reference signal, a number of periodic transmissions of the uplink reference signal, and a bandwidth parameter.

[0186] The characteristic parameter configuration of the uplink reference signal in the time domain and frequency domain includes one or more of the following:

[0187] 1. A common reference point Point A of the resource block grid corresponding to the carrier carrying the uplink reference signal, which may be represented, for example, by an ARFCN value;

[0188] 2. Subcarrier parameters, such as one or more of the offset between the first available RB and the common reference point, subcarrier spacing (15 / 30 / 60 / 120kHz), and carrier bandwidth (number of RBs);

[0189] 3. Information about the uplink reference signal on the activated BWP, such as one or more of the following: the location and bandwidth of the activated uplink BWP, subcarrier spacing, cyclic prefix information, uplink reference signal resource set configuration, and uplink reference signal resource configuration. The uplink reference signal resource set may be an SRS resource set or a positioning SRS resource set; the uplink reference signal resource set configuration includes: the ID of each resource in the resource set, and whether the resource set's periodicity is periodic, aperiodic, or semi-persistent. The resource of the uplink reference signal can be SRS or positioning SRS; the resource configuration of the uplink reference signal includes: resource ID, number of ports (1 / 2 / 4), subcarrier mapping mode (comb2 / comb4), starting symbol position, reloading factor (1 / 2 / 4), frequency domain position, frequency domain offset, periodic characteristics in periodic form (periodic) or aperiodic form (aperiodic) or semi-persistent form (semi-persistent), parameters corresponding to the periodic characteristics, where the parameters corresponding to the periodic characteristics, for example, how many time slots a period spans when periodically transmitted.

[0190] The purpose of configuring the uplink reference signal may be represented by a bitmap or enumeration, which is used to indicate that the requested uplink reference signal is used for positioning data collection in situations such as model training / retraining / inference / testing / validation / monitoring.

[0191] Among them, the number of periodic transmissions of the uplink reference signal, when the uplink reference signal is transmitted periodically, this parameter is used to indicate the number of times the uplink reference signal needs to be transmitted (for example, 1000 times); when the uplink reference signal is transmitted aperiodically, this parameter may not be included in the uplink reference signal configuration.

[0192] Among them, the bandwidth parameter is used to indicate the system bandwidth of the uplink reference signal, which can be one of 5MHz, 10MHz, 20MHz, 40MHz, 50MHz, 80MHz, 100MHz, etc. in frequency range 1 (FR1), or one of 50MHz, 100MHz, 200MHz, 400MHz, etc. in frequency range 2 (FR2).

[0193] S82. The first radio access network device responds to the second custom request message and configures an uplink reference signal for the target terminal device based on the third information.

[0194] The first radio access network device uses the second uplink reference signal configuration as a configuration basis to meet the second uplink reference configuration requirement as much as possible, wherein the first radio access network device actually performs the first uplink reference signal configuration for the target terminal device.

[0195] S83. The first wireless access network device sends a second customized response message based on NRPPa to the LMF. The second customized response message carries fourth information. The fourth information includes: whether the second uplink reference signal configuration is successful, the configuration error that occurs when the first wireless access network device configures the uplink reference signal for the target terminal device, and the first uplink reference signal configuration performed by the first wireless access network device for the target terminal device.

[0196] The first radio access network device may indicate whether the second uplink reference signal configuration requested by the first radio access network device for the LMF is successful by configuring a corresponding indicator bit. This may be indicated in the form of a bitmap or enumeration, with the options including: configuration success, configuration failure.

[0197] Among them, a configuration error that occurs when the first radio access network device configures an uplink reference signal for the target terminal device can indicate the type of error that occurred in the form of a bitmap or enumeration, and the error types that can be indicated include, for example, not understanding, missing, etc. It should be noted that this parameter is sent when an error occurs during the configuration process, and if no error occurs, this parameter may not be sent.

[0198] The first uplink reference signal configuration may include configuration information of one or more uplink reference signals actually configured for the target terminal device. The content included in the configuration information of each uplink reference signal may refer to the relevant description of the second uplink reference signal configuration. For the sake of brevity, it is not repeated here. The first radio access network device feeds back the first uplink reference signal configuration to the LMF, which can be used by the LMF to verify whether the actual uplink reference signal configuration of the target terminal device is the same as the uplink reference signal configuration expected by the LMF.

[0199] The method of this embodiment, by adding a signaling process based on NRPPa, enables LMF to request a specific uplink reference signal configuration for positioning data collection, thereby meeting the positioning data collection requirements.

[0200] FIG9 is a flow chart of a positioning data collection method provided by another embodiment of the present application. Referring to FIG9 , the method of this embodiment includes:

[0201] S91. The LMF sends an NRPPa-based positioning information request message (NRPPa positioning information request) to a first radio access network device, where the positioning information request message carries third information.

[0202] In this embodiment, a new information element may be added to the positioning information request message to carry the third information, thereby not changing the existing interaction process. The first radio access network device may obtain the third information from the new information element in the positioning information request message.

[0203] The content included in the third information can be referred to the description of the embodiment of FIG8 , and will not be repeated here.

[0204] S92. The first radio access network device responds to the positioning information request message and configures an uplink reference signal for the target terminal device based on the third information.

[0205] The implementation method of uplink reference signal configuration in this step is similar to that of embodiment S82 in FIG8 , and will not be repeated here.

[0206] S93. The first wireless access network device sends an NRPPa-based positioning information response message (NRPPa positioning information response) to the LMF, carrying the fourth information. The fourth information includes: whether the second uplink reference signal configuration is successful, the configuration error that occurs when the first wireless access network device configures the uplink reference signal for the target terminal device, and the first uplink reference signal configuration performed by the first wireless access network device for the target terminal device.

[0207] The positioning information response message is a message defined in the existing NRPPa interaction process and is used to respond to the positioning information request message. In this application, a new information element can be added to the positioning information response message, and the new information element is used to carry the fourth information. The LMF can obtain the fourth information from the new information element of the positioning information response message.

[0208] The content included in the fourth information can be referred to the description of the embodiment of Figure 8, and will not be repeated here.

[0209] The method of this embodiment uses the existing interaction process of NRPPa to enable LMF to request a specific uplink reference signal configuration for positioning data collection, thereby meeting the positioning data collection requirements.

[0210] In this application, when there are a large number of wireless access network devices participating in positioning data collection, the LMF needs to synchronously start / stop each wireless access network device / TRP participating in positioning data collection, thereby avoiding additional data cleaning work after the measurement data is reported. Based on this, this application adds a new signaling process to synchronously start / stop data collection for multiple wireless access network devices.

[0214] S102. LMF sends a positioning information request message / a second customized request message based on NRPPa to the first radio access network device.

The first radio access network device sends an NRPPa-based positioning information response message (NRPPa positioning information response) / a second customized response message to the LMF. The NRPPa-based positioning information response message / the second customized response message is used to send the actual uplink reference signal configuration of the target terminal device, i.e., the first uplink reference signal configuration, to the LMF.

[0219] Next, the uplink reference signal transmission of the target terminal device is activated through S105a to S105c.

[0225] The first customized request message may be called an NRPPa-based data collection measurement configuration request message (NRPPa data collection measurement config request). In this way, the LMF may send the first information to all radio access network devices participating in data collection through the first customized request message. In this way, the LMF no longer needs to send the existing NRPPa-defined measurement request message (NRPPa measurement request) to the radio access network devices.

[0226] S107: Each wireless access network device participating in positioning data collection performs positioning data collection configuration based on the first information.

[0227] S108a. The LMF sends an NRPPa-based positioning activation request message (NRPPa positioning activation request) to the first radio access network device.

[0229] S108c. The first radio access network device sends an NRPPa-based positioning activation response message (NRPPa positioning activation response) to the LMF.

[0230] This embodiment shows that uplink reference signal transmission of the target terminal device is activated through S105a to S105c before S106, that is, S105a to S105c correspond to activation timing 1. In other embodiments, uplink reference signal transmission of the target terminal device can be activated through S108a to S108c after S106, that is, S108a to S108c correspond to activation timing 2. In actual applications, any timing can be selected for activation.

[0231] S109. The LMF sends fifth information to each radio access network device participating in positioning data collection. The fifth information includes an activation indication bit and a first status indication bit. The activation indication bit is used to instruct the radio access network device to activate measurement of uplink reference signals for the target terminal device and to send measurement data. The first status indication bit is used to indicate the reason for activation. In response, the radio access network device receives the fifth information and activates positioning data collection based on the fifth information.

[0232] In some embodiments, LMF may send a newly added custom message based on NRPPa to each wireless access network device participating in positioning data collection. For example, the newly added custom message is named NRPPa data collection activation, and the newly added custom message carries the fifth information through a cell.

[0233] The activation indication bit may be represented in the form of a bitmap or an enumeration, and when indicating activation, the option is configured to be activated.

[0234] The first state indication bit may be represented in the form of a bitmap or enumeration, and the reason for indicating activation may be, but is not limited to: the activation of data collection is for data collection in training / retraining / inference / verification / monitoring and the like.

[0240] S1013. The LMF sends seventh information to each radio access network device involved in positioning data collection. The seventh information includes a deactivation indication bit and a second status indication bit. The deactivation indication bit is used to instruct the radio access network device to deactivate measurement of uplink reference signals for the target terminal device and transmission of measurement data. The second status indication bit is used to indicate the reason for deactivation. Accordingly, the radio access network device receives the seventh information and, based on the seventh information, deactivates measurement of uplink reference signals for the target terminal device and transmission of measurement data.

[0241] In some embodiments, LMF may send a new custom message based on NRPPa to each wireless access network device participating in positioning data collection.

S1014 terminates the positioning process, i.e., completes positioning data collection.

[0245] In the method of this embodiment, the LMF sends activation-related instructions and deactivation-related instructions to all wireless access devices participating in positioning data collection, thereby synchronously starting / stopping data collection of multiple wireless access network devices, thereby reducing LMF resource waste.
