Description

Information exchange methods and devices related to wireless positioning methods Technical Field

[0001] This application relates to the field of communication technology. Background Technology

[0002] With the commercialization of 5G (fifth-generation mobile communication technology), and especially the large-scale development of the industrial internet industry, the application of artificial intelligence (AI) technology in the field of wireless communication has sprung up like mushrooms after rain. Among them, AI / ML model management based on machine learning (ML), especially deep learning (DL) or reinforcement learning technology, is particularly important in various wireless AI applications.

[0003] Since AI / ML methods are trained using measurement data acquired through wireless channels, and the statistical characteristics of measurement data in wireless communication are strongly correlated with factors such as the channel environment, AI / ML methods cannot be used continuously during the operation of a wireless communication system. Applicability assessment is necessary. When the applicability of an AI / ML method is poor, two options are available: 1) switch to another more applicable AI / ML method; 2) switch or fallback to a non-AI / ML method. Similarly, if the system detects an available applicable AI / ML method while running a non-AI / ML method, a switch from the non-AI / ML method to an AI / ML method is also required.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application. Summary of the Invention

[0005] The inventors discovered that, because AI / ML technology is a relatively new and unstandardized technology, the 3GPP (3rd Generation Partnership Project) standards lack signaling, procedures, or frameworks for switching between AI / ML methods and other methods. To introduce such a mechanism, it is necessary to analyze it in conjunction with specific use cases of AI / ML in wireless communication, such as wireless positioning on the terminal side.

[0006] In existing wireless positioning technologies, network devices (such as LMF) instruct and configure the positioning method used by terminal devices based on information collected from upstream and downstream sources, such as LCS (Location Services) service requests, QoS (Quality of Service) information, and UE (User Equipment) capability information. They can also continuously send LPP (LTE Positioning Protocol) assistance data to help terminal devices locate themselves. When the terminal device obtains the positioning result, it can report and save the location information according to the LMF configuration.

[0007] When the terminal or network detects that the currently configured positioning method is not functioning correctly, it sends an error message to the other side. Upon receiving the error message, the other side terminates all positioning processes associated with the current LPP Transaction ID. If the current wireless positioning method is terminated, the LMF determines whether to initiate a new positioning process based on the collected information.

[0008] This shows that the selection, switching, and termination process of wireless positioning methods in existing technologies is very simple and not suitable for scenarios where AI / ML methods and non-AI / ML methods coexist.

[0009] To address at least one of the above-mentioned problems or other similar issues, embodiments of this application provide an information interaction method and apparatus related to a wireless positioning method.

[0014] A transmitting unit sends first configuration information to a terminal device, the first configuration information being used to instruct the terminal device to switch and / or terminate and / or select and / or reselect the wireless positioning method;

[0015] The terminal device selects, reselects, switches, or terminates the wireless positioning method based on the first configuration information.

[0016] According to another aspect of the embodiments of this application, a wireless positioning method-related information interaction method is provided, applied to a terminal device, the method comprising:

[0017] The terminal device receives first configuration information sent by the network device, the first configuration information being used to instruct the terminal device to switch and / or terminate and / or select and / or reselect the wireless positioning method;

[0018] The terminal device selects, reselects, switches, or terminates the wireless positioning method based on the first configuration information.

[0019] According to another aspect of the embodiments of this application, an information interaction device related to a wireless positioning method is provided, configured in a terminal device, the device comprising:

[0058] Furthermore, in the following explanation, "when," "if," and "under certain circumstances" have the same meaning and can be used interchangeably.

[0059] First aspect of the embodiments

[0060] This application provides an information interaction method related to a wireless positioning method, involving the transmission and reception of information between a terminal device and a network device. This information is used for the selection, switching, and termination of wireless positioning methods on the terminal side, including the selection and switching between AI / ML positioning methods, the fallback from an AI / ML positioning method to a non-AI / ML positioning method, and the switching from a non-AI / ML positioning method to an AI / ML positioning method. This is described from the perspective of the network device. The network device can be, for example, an LMF (Location Management Function) acting as a network-side positioning function management element, interacting with the terminal device on information related to the wireless positioning method. Furthermore, the network device can also interact with a second network device, which can be, for example, an AMF (Agency Management Function) acting as a network-side management element. This application is not limited to this; the network device and the second network device can also be other network elements, depending on the implementation scenario.

[0061] Figure 2 is a schematic diagram of an information interaction method related to the wireless positioning method according to an embodiment of this application. As shown in Figure 2, the method includes:

[0062] 210. The network device sends first configuration information to the terminal device, which instructs the terminal device to switch and / or terminate and / or select and / or reselect the wireless positioning method; thereby, the terminal device can select, reselect, switch or terminate the wireless positioning method according to the first configuration information.

[0063] It is worth noting that Figure 2 above is only an illustrative description of the embodiments of this application, but this application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted, and other operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description in Figure 2 above.

[0064] Figure 3 is a schematic diagram of information interaction between network devices and terminal devices according to the method of the above embodiments, showing the case where LMF is the network device and UE is the terminal device.

[0065] As shown in Figure 3, in step 310, the LMF sends first configuration information to the UE, which instructs the UE to switch and / or abort and / or select and / or reselect the radio positioning method on the UE side. In step 320, after receiving the first configuration information, the UE can perform corresponding operations on the radio positioning method on the UE side according to the first configuration information, such as selecting, reselecting, switching, or aborting.

[0066] In the above embodiments, as shown in Figure 3, the LMF can also establish an LPP session between the LMP and the UE based on the content of the service request after receiving a location service request triggered by a higher layer, and perform signaling interactions with the UE related to the location process, such as capability information and AI / ML applicability information. Furthermore, the LMF can instruct and / or configure the wireless positioning method used by the UE based on the information exchanged. The UE runs the configured wireless positioning method under the assistance and monitoring of the LMF; details can be found in related technologies, which will not be elaborated here.

[0067] In the above embodiments, the LMF determines the wireless positioning method. This can be the first time the LMF determines the wireless positioning method, meaning that the UE has not been configured or instructed on the wireless positioning method before. Alternatively, it can be a second time the LMF determines the wireless positioning method for the UE based on the information exchange with the UE.

[0068] In the above embodiments, the operation of the UE running the configured radio positioning method under the assistance and monitoring of the LMF can be performed after the LMF has determined the radio positioning method, as shown in Figure 3. However, this application is not limited to this, and the operation can also be performed at other suitable times.

[0069] According to the above embodiments, by exchanging information related to the wireless positioning method, the terminal device and the network device can select a suitable wireless positioning method for the terminal side, thereby improving the accuracy and continuity of wireless positioning and thus enhancing the overall performance and user experience of the wireless communication system.

[0070] In some embodiments, as shown in FIG2, the method may further include:

[0071] 220: The network device sends second configuration information to the terminal device, the second configuration information being used to configure the terminal device to report first information to the network device, the first information being related to a wireless positioning method, the wireless positioning method including at least one first positioning method and / or at least one second positioning method;

[0072] 230: The network device receives the first information mentioned above, and determines the content and / or timing of sending the first configuration information based on the first information, or determines the wireless positioning method on the terminal side.

[0073] For example, as shown in Figure 3, the LMF can also send second configuration information to the UE (operation 330). This second configuration information is used to configure the UE to report first information to the LMF. The UE sends the first information to the LMF according to the second configuration information (operation 340). The first information may be related to the selection, reselection, handover, fallback, termination, etc. of the wireless positioning method. The LMF determines the content and / or timing of sending the first configuration information based on the first information. Specific implementation methods for the second configuration information and the first information will be described in later embodiments.

[0074] In some embodiments, as shown in FIG2, the method may further include:

[0075] 240: The network device receives the second information sent by the terminal device and confirms the terminal device's relevant operations on the wireless positioning method based on the content of the second information.

[0076] For example, as shown in Figure 3, after receiving the first configuration information, the UE can also send second information to the LMF (operation 350). This second information can be feedback from the UE regarding its operation of the wireless positioning method, such as completion of the operation, the reason or error information for the operation, or information on terminating the current wireless positioning method. The LMF can confirm the UE's operation of the wireless positioning method based on the content of this second information. Specific implementation details of this second information will be described in later embodiments.

[0077] It is worth noting that Figure 3 above is only an illustrative description of the embodiments of this application, but this application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted, and other operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description in Figure 3 above.

[0078] For example, operation 330 may be executed before operation 310; operation 330 may be executed both before and after operation 310; operation 350 may be executed after operation 310; operation 320 may be executed after operation 350, and so on.

[0079] Figure 4 is another schematic diagram of information interaction between network devices and terminal devices according to the method of the above embodiments, showing the case where LMF is the network device and UE is the terminal device.

[0080] In the example of Figure 4, the first configuration information is sent before the AI / ML function or model is activated on the UE side. This first configuration information indicates the UE's operation when the AI / ML function or model is not applicable. That is, the network side pre-configures the switching, reselection, and rollback of the AI / ML positioning method on the UE side before the AI / ML function or model is activated.

[0081] As shown in Figure 4, the interaction process includes at least the following:

[0082] 410: The LMF interacts with the UE to provide capability information related to AI / ML positioning methods and non-AI / ML positioning methods, as well as functional applicability information related to AI / ML positioning methods;

[0083] 420: The LMF sends the first configuration information to the UE;

[0084] 430: The UE performs the corresponding operation based on the first configuration information.

[0085] In addition, as shown in Figure 4, the interaction process also includes:

[0086] 440: LMF configuration UE activates AI / ML functions or models;

[0087] 450: UE activates AI / ML functions or models.

[0088] It is worth noting that Figure 4 above is only an illustrative description of the embodiments of this application, but this application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted, and other operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description in Figure 4 above.

[0089] In the example above, operation 420 is performed before operation 450. That is, before the AI / ML function is activated, the LMF sends the first configuration information to the UE. This application does not restrict the execution order of operation 420 and operation 440. As shown in Figure 4, operation 440 can be executed first and then operation 420 can be executed, or operation 420 can be executed first and then operation 440 can be executed.

[0090] For example, the first configuration information may be sent before the LMF and UE send and / or receive the applicability information of the AI / ML function or model, or simultaneously with the applicability information of the AI / ML function or model, or after the LMF and UE send and / or receive the applicability information of the AI / ML function or model and before the network device configures and activates the AI / ML function or model, or simultaneously with the network device configures and activates the AI / ML function or model, or after the network device configures and activates the AI / ML function or model, and so on. The AI / ML function or model is used for wireless positioning.

[0091] In the example above, during operation 420, the LMF can send first configuration information to the UE via LPP signaling, such as AssistanceData and / or RequestLocationInformation. This first configuration information may include at least one of the following:

[0092] The content of switching, reverting, or reselecting wireless positioning methods;

[0093] Conditions for the switching, rollback, or reselection of wireless positioning methods and / or termination;

[0094] Assistance information that supports switching, rewinding, or reselecting wireless positioning methods.

[0095] The switching, rollback, or reselection of the aforementioned wireless positioning method can be an indication of a specific wireless positioning method (the first positioning method and / or the second positioning method), including explicit and / or implicit indications, such as the identifier and / or name corresponding to the wireless positioning method, the identifier and / or name corresponding to the AI / ML function or model, and so on.

[0096] The conditions for the occurrence and / or termination of the switching, rollback or reselection of the above wireless positioning method include, for example, the threshold for the inference performance of the AI / ML positioning method, the judgment condition for the adaptability of AI / ML functions, the timer between multiple switching or reselection, etc.

[0097] The auxiliary information for the aforementioned wireless positioning method that supports switching, reverting, or reselecting can be used for measurement, reporting, and optimization of the aforementioned positioning method. For example, it can include DL-PRS (Downlink Positioning Reference Signal) configuration information and area applicability information required for the measurement of the aforementioned wireless positioning method (first positioning method and / or second positioning method).

[0098] This auxiliary information may be the same as, partially the same as, or different from the configuration information of the AI / ML function or model to be activated. This auxiliary information may be sent simultaneously with or at different times from the configuration information of the AI / ML function or model to be activated. This auxiliary information may share the same LPP Transaction identifier with the AI / ML function or model to be activated, or it may be associated with different LPP Transaction identifiers. If it shares the same LPP Transaction identifier, this auxiliary information can use the identifier information to distinguish between the AI / ML function or model to be activated and the aforementioned switching, reselection, or rollback positioning methods.

[0099] In the example above, during operation 430, the UE may perform at least one of the following operations based on the first configuration information:

[0100] Complete the activation, deactivation, switching, or reselection of the AI / ML function or model used for wireless positioning;

[0101] The measurement and reporting process of the wireless positioning method is initiated, which includes at least one first positioning method and / or at least one second positioning method;

[0102] Send a second message to the network device.

[0103] In some possible implementations, the second information includes at least one of the following:

[0104] The instruction provides confirmation feedback information indicating that at least one of the following operations has been completed: activation, deactivation, switching, reselection, or rollback of the AI / ML function or model corresponding to at least one first positioning method.

[0105] The reason for performing the above operation or the error message;

[0106] Information requesting termination of the current wireless positioning method (first positioning method or second positioning method).

[0107] For example, the second information is a confirmation feedback message, which indicates that the activation operation of at least one AI / ML function or model corresponding to the first positioning method has been completed.

[0108] For example, the second information is a confirmation feedback message, which indicates that a rollback operation has been completed for at least one AI / ML function or model corresponding to the first positioning method, and the second information also includes the reason for performing the aforementioned rollback operation.

[0109] For example, the second information is a request to terminate the current wireless positioning method (the first positioning method or the second positioning method).

[0110] In the above example, the reasons for performing the above operation or the error message may be as follows: the terminal device cannot meet the conditions required to execute the current positioning method, such as the remaining battery power of the device, the device temperature, etc.; the terminal device believes that the above positioning method cannot meet the quality requirements of the current positioning service, such as the positioning accuracy is too low, the positioning latency is too long, etc.; the terminal device believes that the applicability of the AI / ML function or model corresponding to the above positioning method has changed; the terminal device believes that the current measurement data and / or other data used for the above positioning method cannot meet the data quality and / or quantity requirements; the terminal device detects that there are other available positioning methods with better performance, etc.

[0111] In the above example, operations 410, 420 and 430 can be repeated multiple times as needed, and the order of execution is not restricted. For example, LMF can resend the first configuration information without re-performing the information exchange of operation 410, that is, execute operation 420; or, for another example, LMF can re-perform the information exchange of operation 410 without sending the first configuration information, that is, without executing operation 420.

[0112] Figure 5 is another schematic diagram of information interaction between network devices and terminal devices according to the method of the above embodiments, showing the case where LMF is the network device and UE is the terminal device.

[0113] In the example of Figure 5, the first configuration information is sent after the AI / ML function or model has been activated, meaning that the switching, reselection, or rollback of the AI / ML function or model is independent of the activation process. After the AI / ML function or model is activated, the LMF collects information as needed and configures operations such as switching, reselection, or rollback of the radio positioning method on the UE side. Furthermore, in the example of Figure 5, both the LMF and the UE can trigger the LMF to send the first configuration information.

[0114] As shown in Figure 5, the interaction process includes at least the following:

[0115] 510: LMF interacts with UE to provide capability information related to AI / ML localization methods and information on the functional applicability of AI / ML localization methods;

[0116] 520: The LMF sends second configuration information to the UE, which configures the UE to send first information. The first information is used to assist the LMF in determining the content of the first configuration information, for example, related to the above-mentioned wireless positioning method, which includes at least one first positioning method and / or at least one second positioning method.

[0117] 530: The UE sends the first information to the LMF according to the second configuration information;

[0118] 540: The LMF determines the content of the first configuration information based on the first information and sends the first configuration information to the UE;

[0119] 550: The UE performs positioning method-related operations based on the first configuration information.

[0120] It is worth noting that Figure 5 above is only an illustrative description of the embodiments of this application, but this application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted, and other operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description in Figure 5 above.

[0121] In the example above, during operation 510, the LMF can indicate the available AI / ML functions or models to the UE based on the interaction results, and send configuration information to the UE to activate and use wireless positioning AI / ML information. Optionally, the LMF can also configure the UE to perform information interaction related to non-AI / ML positioning methods.

[0122] In the above example, the first information may include or indicate at least one of the following:

[0123] Information on the applicability and / or inference performance of activated AI / ML features or models;

[0124] Information on the applicability of inactive AI / ML features or models, such as AI / ML features or models whose applicability has changed;

[0125] Information related to the second positioning method;

[0126] Are there any new available AI / ML functions or models, and information about those new available AI / ML functions or models, which correspond to the first localization method;

[0127] Terminal device and environmental change information, such as UE speed and storage status;

[0128] The terminal device's preference or selection information for positioning methods, such as the name and / or identification information of the positioning method; the measurement and / or data information required by the positioning method, such as reference signals, auxiliary data, etc.; the identification information, meta information, and meta data information of the AI / ML function and / or model corresponding to the positioning method.

[0129] In the example above, the second configuration information can be the event, condition, threshold, etc., corresponding to the first information. Different configurations can correspond to different reporting information in the first information.

[0130] For example, LMF can configure a threshold for the inference performance of AI / ML functions or models to trigger the UE to report the applicability information of AI / ML functions or models. LMF can also configure the UE to periodically report whether there are new available AI / ML functions or models.

[0131] In the example above, the content of the second configuration information and the corresponding content in the first information can be one-to-one, one-to-many, many-to-one, or many-to-many.

[0132] For example, in a one-to-one relationship: if the content of the second configuration information is information A, then the first information reports information A according to the configuration content. In a one-to-many relationship: if the content of the second configuration information is information A, then the first information selects and reports at least one of information A1, A2, ..., AN according to the configuration content; this A1, A2, ..., AN information is a sub-information of information A. In many-to-one and many-to-many relationships: if the content of the second configuration information is information A1, A2, ..., AN, and this A1, A2, ..., AN information is a sub-information of information A, then the first information reports at least one of information A1, A2, ..., AN according to the configuration, and may optionally report sub-information of information A such as An+1, An+2, etc., that are not indicated in the second configuration information.

[0133] In the above example, the second configuration information can configure the terminal device to report the first information. The terminal device can select from the entire set of the first information and report it.

[0134] For example, if the second configuration information configures the terminal device to report information A and / or information B, the terminal device can choose not to report any information, or only report information A, or only report information B, or report information A and information B separately, or report information A and information B simultaneously.

[0135] In the example above, the second configuration information can be carried by at least one LPP signaling message, such as AssistanceData or RequestLocationInformation, etc.

[0136] In the example above, if the first information includes information about new available AI / ML functions or models on the terminal side, the LMF can configure the UE to repeat the above operation 510, that is, configure the UE to interact with the LMF regarding AI / ML capabilities and / or functional applicability information. The content of the interaction can be the same as before or different from before. That is, the LMF can configure the UE to interact with the LMF on the same content as before, or configure the UE to interact with the LMF on the parts that are different from before, and so on.

[0137] In the above example, the relevant content of the first configuration information and the relevant operations of the UE have been described in the previous embodiments, and will not be repeated here.

[0138] Figure 6 is another schematic diagram of information interaction between network devices and terminal devices according to the method of the above embodiments, showing the case where LMF is the network device and UE is the terminal device.

[0139] The example in Figure 6 illustrates another implementation of the first configuration information: the UE decides on operations such as switching, backtracking, or reselection, while the network can confirm or reject the decision reported by the UE through the first configuration information without requiring the network to actively specify it. This provides the UE with a high degree of freedom and is suitable for scenarios where AI / ML positioning methods and traditional non-AI / ML positioning methods (legacy methods) are categorized under a single wireless positioning method.

[0140] As shown in Figure 6, the interaction process includes at least the following:

[0141] 610: LMF interacts with UE to provide capability information related to AI / ML localization methods and information on the functional applicability of AI / ML localization methods;

[0142] 620: The LMF sends second configuration information to the UE, which instructs the UE to report first information related to the radio positioning method;

[0143] 630: The UE receives information from the LMF and initiates the wireless positioning process;

[0144] 640: When the UE detects that it needs to reselect, back off, or switch the wireless positioning method, it sends the first information mentioned above to the LMF according to the configuration of the second configuration information;

[0145] 650: The LMF sends the first configuration information to the UE, confirming or rejecting the UE's request to reselect, roll back, or switch the radio positioning method;

[0146] 660: The UE performs positioning method-related operations based on the first configuration information.

[0147] It is worth noting that Figure 6 above is only an illustrative description of the embodiments of this application, but this application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted, and other operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description in Figure 6 above.

[0148] In the example above, during operation 610, the LMF can also send indication information and corresponding configuration information to the UE, specifying a radio positioning method, such as DL-TDOA (downlink time difference of arrival), DL-AOA (downlink angle of arrival), etc. This radio positioning method does not distinguish between AI / ML or non-AI / ML, that is, the radio positioning method specified by the LMF can be the first positioning method and / or the second positioning method mentioned above.

[0149] In the example above, during operation 620, if the LMF discovers that the UE has AI / ML capabilities during the aforementioned capability information exchange, the LMF may choose to send second configuration information to the UE. This second configuration information instructs the UE to report first information related to the radio positioning method. This first information may include radio positioning method-related information, or it may only include the radio positioning method's index information, or both.

[0150] In the example above, during operation 630, the UE initiates the radio positioning process based on information from the LMF, such as the aforementioned indication information and / or the corresponding configuration information.

[0151] In the example above, in operation 640, after receiving the first information, the LMF can confirm the wireless positioning method on the terminal side based on the first information.

[0152] In the example above, if the UE does not explicitly indicate that the first positioning method is being switched in operation 640, the UE may optionally indicate the relevant content of the switched first positioning method in other reported information, such as in the second information, such as adding additional information to ProvideLocationInformation.

[0153] In the above example, the first configuration information is only used to confirm or decide the UE's request to reselect, backtrack, or switch the wireless positioning method, and does not have the functions of the aforementioned embodiments, thereby giving the UE more freedom.

[0154] In the example above, the relevant operations for the UE in operation 660 have already been explained, and will not be repeated here.

[0155] Figure 7 is another schematic diagram of information interaction between network devices and terminal devices according to the method of the above embodiments, showing the case where LMF is the network device and UE is the terminal device.

[0156] In the example in Figure 7, the positioning method on the UE side is switched from a non-AI / ML method to an AI / ML method. Since the AI / ML method generally outperforms the non-AI / ML method when the applicability conditions are met, the UE can report immediately when it finds an applicable AI / ML method available, even if the performance of the non-AI / ML method has not completely deteriorated.

[0157] As shown in Figure 7, the interaction process includes at least the following:

[0158] 710: LMF interacts with UE to provide capability information related to AI / ML localization methods and information on the functional applicability of AI / ML localization methods;

[0159] 720: UE initiates wireless positioning process;

[0160] 730: If the UE detects that an available AI / ML method is available, it sends a second message to the LMF;

[0161] 740: LMF performs the relevant operation based on the second information;

[0162] 750: The LMF sends the first configuration information to the UE;

[0163] 760: The UE performs relevant operations based on the first configuration information.

[0164] It is worth noting that Figure 7 above is only an illustrative description of the embodiments of this application, but this application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted, and other operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description in Figure 7 above.

[0165] In the example above, during operation 730, the UE can report the second information to the LMF via LPP signaling, such as AssistanceData.

[0166] In the example above, during operation 740, the LMF receives the second information sent by the UE and can perform at least one of the following actions:

[0167] If the AI / ML positioning method indicated by the second information corresponds to an AI / ML function or model sent and / or received between the LMF and the UE, for example, if the AI / ML function or model has been interacted in operation 710, then the LMF can send the aforementioned first configuration information to the UE to confirm the reselection or switching of the wireless positioning method. Optionally, the LMF can also send configuration information for the new AI / ML function or model to the UE.

[0168] If the AI / ML positioning method indicated by the second information does not correspond to an AI / ML function or model sent and / or received between the LMF and the UE, for example, if the AI / ML function or model has not been interacted in operation 710, then the LMF may perform at least one of the following operations:

[0169] Initiate the sending and / or receiving of applicability information for new AI / ML functions or models, and send the aforementioned first configuration information;

[0170] If the LMF detects that the applicability information on the network side has not changed, it can directly send the aforementioned first configuration information;

[0171] LMF can also configure a timer for the UE using the first configuration information mentioned above, instructing the UE to maintain the current non-AI / ML positioning method or switch to a new AI / ML positioning method before the timer expires, and to send and / or receive applicability information for AI / ML functions or models before the timer expires.

[0172] In the example above, during operation 760, the UE can switch the positioning method based on the received first configuration information.

[0173] In the above example, the relevant content of the first configuration information and the relevant operations of the UE have been described in the previous embodiments, and will not be repeated here.

[0174] The above embodiments are merely illustrative examples of embodiments of this application, but this application is not limited thereto, and appropriate modifications can be made based on the above embodiments. For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined.
