In this case, the terminal devices can also be configured to have all or part of the functions of the access network devices. Furthermore, terms such as "uplink" and "downlink" can be replaced with terms corresponding to communication between terminal devices (e.g., "sidelink").

[0177] Currently, AI or machine learning (ML) can be applied to wireless communication systems to achieve the positioning of terminal devices.

[0178] In some embodiments, the process of locating a terminal device based on AI is achieved through an AI model or AI function. Taking the location of a terminal device based on an AI model as an example, different datasets can be used to train the corresponding AI model for different location application scenarios. The AI ​​model can be deployed on the terminal device side, the access network device side, or the LMF network element side.

[0179] In some embodiments, the process of locating a terminal device based on ML is implemented through an ML model or ML function. Taking the location of a terminal device based on an ML model as an example, different datasets can be used to train the corresponding ML model for different location application scenarios. The ML model can be deployed on the terminal device side, the access network device side, or the LMF network element side.

[0180] In some embodiments, the terms “AI”, “AI function”, “AI model”, “ML”, “ML function”, and “ML model” can be used interchangeably.

[0181] In some embodiments, taking the process of locating a terminal device based on AI as an example, there are at least the following positioning methods: direct AI / ML positioning and AI / ML assisted positioning.

[0182] Direct AI / ML positioning refers to the method of directly inferring the location information of a terminal device through an AI model or an ML model. Figure 1b This is a schematic diagram illustrating direct AI / ML localization as shown in an embodiment of this disclosure, such as... Figure 1b As shown, taking direct AI positioning as an example, the input to the AI ​​model is multiple measurement data (in... Figure 1b For example, it can include measurement data of TPR0, measurement data of TRP1, ..., TRP N-1 The AI ​​model outputs the location information of the terminal device, based on the measurement data. Taking direct ML positioning as an example, the input to the ML model is multiple measurement data points (in...). Figure 1b For example, it can include measurement data of TPR0, measurement data of TRP1, ..., TRP N-1 The measurement data), the output of the ML model is the location information of the terminal device.

[0183] In some embodiments, for any TRP, the TRP can send a PRS to the terminal device, and then the terminal device measures the received PRS to obtain the measurement data of the TRP.

[0184] In some embodiments, the measurement data input to the AI ​​model or ML model may include, for example, channel impulse response, power spectral density, reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), etc., but are not limited thereto.

[0185] AI / ML-assisted positioning refers to a method that uses AI or ML models to provide intermediate measurement results, and then uses other positioning methods to determine the location information of the terminal device based on the intermediate measurement results.

[0186] Figure 1c This is a schematic diagram illustrating AI / ML-assisted localization in an embodiment of this disclosure, as shown below. Figure 1c As shown, taking AI-assisted positioning as an example, the input to the AI ​​model is multiple measurement data (in... Figure 1c For example, it can include measurement data of TPR0, measurement data of TRP1, ..., TRP N-1 The AI ​​model outputs multiple positioning measurement results (from the measurement data). Figure 1c For example, it can include the positioning measurement results corresponding to TPR0, the positioning measurement results corresponding to TRP1, ..., TRP N-1 (Corresponding positioning measurement results).

[0187] In some embodiments, for any TRP, the TRP may send a PRS to the terminal device, and then the terminal device measures the received PRS to obtain the measurement data of the TRP.

[0188] In some embodiments, the measurement data input to the AI ​​model or ML model may include, for example, channel impulse response, power spectral density, RSRP, RSRQ, etc., but are not limited thereto.

[0189] In some embodiments, for any TRP, the positioning measurement result corresponding to the TRP can be obtained by processing the measurement data of the TRP using an AI model or an ML model.

[0190] In some embodiments, the positioning measurement results may include, for example, line of sight (LOS), non-line of sight (NLOS), etc., but are not limited thereto.

[0191] Based on the deployment of AI / ML models and the two positioning methods, the following situations exist:

[0192] Scenario 1: The AI / ML model is deployed on the terminal device side, and the positioning method is direct AI / ML positioning;

[0193] Case 2a: The AI / ML model is deployed on the terminal device side, and the positioning method is AI / ML assisted positioning;

[0194] Scenario 2b: The AI / ML model is deployed on the LMF network element side, and the positioning method is direct AI / ML positioning;

[0195] Case 3a: The AI / ML model is deployed on the access network equipment side, and the positioning method is AI / ML assisted positioning;

[0196] Case 3b: The AI / ML model is deployed on the LMF network element side, and the positioning method is AI / ML assisted positioning.

[0197] In cases 1 and 2a above, the AI ​​model / ML model is deployed on the terminal device side. Therefore, in some embodiments, the terminal device needs to acquire first measurement data, which can be used, for example, to train the AI ​​model / ML model; in some embodiments, the terminal device needs to use the AI ​​model / ML model for localization.

[0198] In some embodiments, if the terminal device does not need to continue acquiring the first measurement data, it can be instructed to stop acquiring the first measurement data via a stop message.

[0199] In some embodiments, if the terminal device needs to stop the AI ​​function positioning, it can be instructed to stop the AI ​​function positioning by sending a stop message.

[0200] Figure 1d This is a schematic diagram illustrating the suspension of message transmission as shown in an embodiment of this disclosure, such as... Figure 1d As shown, it includes:

[0201] Step 1: The LTE Positioning Protocol (LPP) process is underway between the serving device and the target device.

[0202] Step 2: The service device sends an LPP abort message to the target device, which indicates the termination of the LPP process; or, the target device sends an LPP abort message to the service device, which indicates the termination of the LPP process.

[0203] In some embodiments, the serving device can be a terminal device, and the target device can be an LMF network element.

[0204] In some embodiments, the serving device can be an LMF network element, and the target device can be a terminal device.

[0205] In some embodiments, if a service device determines that an ongoing LPP process needs to be terminated, the service device can terminate the LPP process by sending an LPP termination message to the target device.

[0206] In some embodiments, if the target device determines that it needs to terminate an ongoing LPP process, the target device can terminate the LPP process by sending an LPP termination message to the service device.

[0207] In some embodiments, the LPP process may include, for example, a process for the terminal device to acquire first measurement data, or a process for the terminal device to perform AI function positioning, but is not limited thereto.

[0208] The solutions of the embodiments of this disclosure will be further described below with reference to the accompanying drawings.

[0209] Figure 2a This is an exemplary interaction diagram of the communication method provided in this embodiment of the disclosure. For example... Figure 2a As shown, the communication method includes the following steps:

[0210] In step S2101, the terminal device sends a stop message to the LMF network element. The stop message is used to instruct the terminal device to stop acquiring the first measurement data.

[0211] In some embodiments, AI functionality is deployed in a terminal device, which can perform AI positioning based on the deployed AI functionality to determine the location information of the terminal device.

[0212] In some embodiments, the AI ​​function deployed in the terminal device may also be referred to as one of the following: AI, AI model, ML, ML function, ML model, etc. In the following embodiments, for ease of description, AI function will be used as an example.

[0213] In some embodiments, the terminal device can directly locate itself based on the AI ​​function deployed in the terminal device. For example, the AI ​​function deployed in the terminal device is an AI model, and the terminal device can input corresponding measurement data into the AI ​​model, which will then output the location information of the terminal device.

[0214] In some embodiments, the terminal device can obtain measurement data in the following manner: the access network device can send PRS to the terminal device, the LMF network element can send PRS configuration information to the terminal device, and the terminal device can receive the PRS sent by the access network device according to the instructions of the PRS configuration information, and measure the received PRS to obtain the corresponding measurement data.

[0215] In some embodiments, the measurement data may include, for example, channel impulse response, power spectral density, RSRP, RSRQ, etc., but are not limited thereto.

[0216] In some embodiments, the measurement data is used for training the AI ​​model, updating the AI ​​model, and fine-tuning the AI ​​model.

[0217] In some embodiments, the terminal device can perform assisted positioning based on AI functions deployed within it. For example, the AI ​​function deployed in the terminal device is an AI model. The terminal device can input corresponding measurement data into the AI ​​model, and then the AI ​​model will output the positioning measurement result of the terminal device. This positioning measurement result is used to assist in positioning the terminal device. For instance, the terminal device can send the positioning measurement result to an LMF network element, and the LMF network element can calculate the location information of the terminal device based on the positioning measurement result.

[0218] In some embodiments, positioning measurement results may include, for example, LOS, NLOS, time of flight, RSRP, RSRPP, Rx-Tx time difference, reference signal time difference (RSTD), etc., but are not limited thereto. Rx-Tx time difference can represent the time difference between the time of transmitting the reference signal and the time of receiving the reference signal. RSTD can represent the time difference between reference signals transmitted by different base stations or different TRPs arriving at the terminal device.

[0219] In some embodiments, the terminal device needs to acquire first measurement data, wherein the first measurement data is used to train an AI model, the AI ​​model is deployed in the terminal device, and the AI ​​model is used by the terminal device to perform AI function positioning.

[0220] In some embodiments, the way a terminal device performs AI function positioning based on the AI ​​model can be either by directly positioning the terminal device based on the AI ​​model or by performing assisted positioning of the terminal device based on the AI ​​model.

[0221] In some embodiments, the LMF network element can send first auxiliary information to the terminal device, the first auxiliary information being used by the terminal device to acquire first measurement data.

[0222] In some embodiments, the first auxiliary information includes first PRS configuration information, which is used to configure the second PRS. The access network device sends the second PRS to the terminal device, and the terminal device receives the second PRS sent by the access network device according to the first PRS configuration information, and measures the second PRS to obtain first measurement data.

[0223] In some embodiments, the first measurement data may include, for example, channel impulse response, power spectral density, RSRP, RSRQ, etc., measured by the terminal device, and the terminal device may train the AI ​​model based on the first measurement data.

[0224] For example, if the AI ​​model is used to directly locate a terminal device, the terminal device can obtain its location information tag through other means. Then, the first measurement data is input into the AI ​​model, which outputs predicted location information. Based on the predicted location information and the terminal device's location information tag, the terminal device adjusts the AI ​​model's parameters to complete one round of training.

[0225] For example, if the AI ​​model is used to assist in the positioning of a terminal device, the terminal device can obtain the positioning measurement result label through other means. Then, the first measurement data is input into the AI ​​model, the AI ​​model outputs the predicted positioning measurement result, and the terminal device adjusts the model parameters of the AI ​​model based on the predicted positioning measurement result and the positioning measurement result label of the terminal device, completing one round of training.

[0226] The terminal device can continuously acquire the first measurement data and train the AI ​​model based on the acquired first measurement data.

[0227] In some embodiments, if the terminal device needs to obtain first measurement data, the LMF needs to periodically send first auxiliary information to the terminal device, and the terminal device obtains the first measurement data based on the first auxiliary information.

[0228] In some embodiments, if the terminal device stops acquiring the first measurement data, the terminal device may send a stop message to the LMF network element. This stop message instructs the terminal device to stop acquiring the first measurement data. By sending the stop message to the LMF network element, the terminal device can indicate to the LMF that it no longer needs to acquire the first measurement data. Correspondingly, the LMF network element receives the stop message from the terminal device and, based on the stop message, can determine that the terminal device no longer needs to acquire the first measurement data.

[0229] In some embodiments, terms such as "stop", "stop", "terminate", "pause", "end", and "no longer" can be used interchangeably. For example, "stop sending the first message" and "stop sending the first message", "terminate sending the first message", "pause sending the first message", "end sending the first message", and "no longer send the first message" can be used interchangeably.

[0230] In some embodiments, the abort message may also be referred to as a termination message, stop message, pause message, LPP abort message, LPP termination message, LPP stop message, LPP pause message, etc., but is not limited thereto. An abort message is a message used to instruct the terminal device to stop acquiring the first measurement data.

[0231] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0232] In some embodiments, "acquire," "get," "obtain," "receive," "transmit," "bidirectional transmission," and "send and / or receive" can be used interchangeably and can be interpreted as receiving from other entities, acquiring from protocols, acquiring from higher layers, obtaining through self-processing, or autonomous implementation. Protocols include, for example, at least one of the 3GPP protocol, Wi-Fi protocol, and audio and / or video protocols.

[0233] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transfer,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.

[0234] In some embodiments, the termination message includes first termination reason information, wherein the first termination reason information is used to indicate the termination of sending first auxiliary information or the termination of acquiring first measurement data, and the first auxiliary information is used by the terminal device to acquire the first measurement data.

[0235] In some embodiments, if the first suspension reason information is used to indicate the suspension of sending the first auxiliary information, the LMF network element may suspend sending the first auxiliary information to the terminal device.

[0236] In some embodiments, if the first termination reason information is used to indicate the termination of acquiring the first measurement data, the LMF network element can determine that the terminal device has terminated the acquisition of the first measurement data based on the first termination reason information. Therefore, the LMF network element can terminate the transmission of the first auxiliary information to the terminal device.

[0237] In step S2102, the LMF network element sends an indication message to the access network device, which is used to indicate the suspension of sending the second PRS to the terminal device.

[0238] In some embodiments, the access network device sends a second PRS to the terminal device, and the terminal device measures the second PRS to obtain first measurement data.

[0239] In some embodiments, the LMF network element receives a stop message from the terminal device. Based on this stop message, it can be determined that the terminal device no longer needs to acquire the first measurement data; that is, the terminal device does not need to measure the second PRS to obtain the first measurement data. Therefore, the access network device does not need to continue sending the second PRS to the terminal device. Thus, the LMF network element sends an indication message to the access network device, which instructs to stop sending the second PRS to the terminal device. Correspondingly, the access network device receives the indication message from the LMF network element and stops sending the second PRS to the terminal device accordingly, thereby saving system overhead.

[0240] In step S2103, the LMF network element sends second auxiliary information to the terminal device. The second auxiliary information is used by the terminal device to perform AI function positioning.

[0241] In some embodiments, the LMF network element receives a stop message sent by the terminal device. The stop message is used to instruct the terminal device to stop acquiring the first measurement data. However, the stop message does not instruct the terminal device to stop AI function positioning. Therefore, the terminal device can continue to perform AI function positioning.

[0242] In some embodiments, when the stop message is used to instruct the terminal device to stop acquiring the first measurement data, the LMF network element sends second auxiliary information to the terminal device. The second auxiliary information is used by the terminal device to perform AI function positioning. Correspondingly, when the stop message is used to instruct the terminal device to stop acquiring the first measurement data, the terminal device receives the second auxiliary information sent by the LMF network element.

[0243] In some embodiments, the second auxiliary information includes PRS configuration information, wherein the PRS configuration information is used to configure a first PRS, the terminal device is used to measure the first PRS to obtain second measurement data, and the second measurement data is used by the terminal device to perform AI function positioning.

[0244] In some embodiments, when the LMF network element receives a stop message from the terminal device, it stops sending auxiliary information for acquiring the first measurement data to the terminal device, but continues to send the second auxiliary information for AI positioning to the terminal device.

[0245] In some embodiments, the second measurement data may include, for example, channel impulse response, power spectral density, RSRP, RSRQ, etc., obtained by the terminal device measuring the first PRS, but is not limited thereto.

[0246] For example, if the AI ​​model is used to directly locate the terminal device, the terminal device can measure the first PRS to obtain the second measurement data, and input the second measurement data into the AI ​​model. The AI ​​model processes the second measurement data and outputs the location information of the terminal device.

[0247] For example, if the AI ​​model is used to assist in the positioning of a terminal device, the terminal device can measure the first PRS to obtain the second measurement data, and input the second measurement data into the AI ​​model. The AI ​​model processes the second measurement data and outputs the positioning measurement result of the terminal device.

[0248] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2103. For example, step S2101 may be implemented as a standalone embodiment, step S2101 + step S2103 may be implemented as a standalone embodiment, and step S2101 + step S2102 may be implemented as a standalone embodiment, but is not limited thereto.

[0249] In some embodiments, steps S2102 and S2103 may be performed in an alternate order or simultaneously. Steps S2101 and S2103 may be performed in an alternate order or simultaneously. Steps S2102 and S2103 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0250] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0251] Figure 2b This is an exemplary interaction diagram two of the communication method provided in this disclosure embodiment. For example... Figure 2b As shown, the communication method includes the following steps:

[0252] Step S2201: The terminal device determines to deactivate the AI ​​function, and the AI ​​function is deployed in the terminal device.

[0253] In some embodiments, AI functionality is deployed in a terminal device, which can perform AI positioning based on the deployed AI functionality to determine the location information of the terminal device.

[0254] In some embodiments, the AI ​​function deployed in the terminal device may also be referred to as one of the following: AI, AI model, ML, ML function, ML model, etc. In the following embodiments, for ease of description, AI function will be used as an example.

[0255] In some embodiments, the terminal device can directly locate itself based on the AI ​​functionality deployed within it. For example, the terminal device can input relevant measurement data into the AI ​​model deployed within it, and then the AI ​​model can output the location information of the terminal device.

[0256] In some embodiments, the measurement data input to the AI ​​model may include, for example, channel impulse response, power spectral density, RSRP, RSRQ, etc., but are not limited thereto.

[0257] In some embodiments, the terminal device can perform assisted positioning based on AI functions deployed in the terminal device. For example, the AI ​​function deployed in the terminal device is an AI model, and the terminal device can input corresponding measurement data into the AI ​​model, which will then output the positioning measurement results of the terminal device.

[0258] In some embodiments, the positioning measurement result is used to assist in locating the terminal device. For example, the terminal device can send the positioning measurement result to the LMF network element, and the LMF network element can calculate the location information of the terminal device based on the positioning measurement result of the terminal device.

[0259] In some embodiments, positioning measurement results may include, for example, LOS, NLOS, time of flight, RSRP, RSRPP, Rx-Tx time difference, RSTD, etc., but are not limited thereto.

[0260] In some embodiments, if the terminal device needs to perform AI function positioning, the LMF network element sends second auxiliary information to the terminal device. The second auxiliary information includes PRS configuration information, wherein the PRS configuration information is used to configure a first PRS, and the terminal device is used to measure the first PRS to obtain second measurement data. The second measurement data is used by the terminal device to perform AI function positioning.

[0261] In some embodiments, the second measurement data may include, for example, channel impulse response, power spectral density, RSRP, RSRQ, etc., obtained by the terminal device measuring the first PRS, but is not limited thereto.

[0262] For example, if the AI ​​function deployed in the terminal device is an AI model, which is a model used to directly locate the terminal device, then the terminal device can measure the first PRS, obtain the second measurement data, and input the second measurement data into the AI ​​model. The AI ​​model processes the second measurement data and outputs the location information of the terminal device.

[0263] For example, if the AI ​​function deployed in the terminal device is an AI model, which is used to assist in the positioning of the terminal device, then the terminal device can measure the first PRS, obtain the second measurement data, and input the second measurement data into the AI ​​model. The AI ​​model processes the second measurement data and outputs the positioning measurement result of the terminal device.

[0264] In some embodiments, the terminal device can monitor the AI ​​function in a certain way. If the positioning performance of the AI ​​function deteriorates or the AI ​​function fails to meet the positioning requirements of the terminal device, the terminal device determines that the AI ​​function needs to be activated.

[0265] In some embodiments, the AI ​​function deployed in the terminal device needs to be under certain conditions to be able to locate the terminal device well. If the certain conditions are not met, the positioning performance of the AI ​​function will deteriorate.

[0266] In some embodiments, the terminal device may, for example, measure the signal strength of a first PRS, and if the signal strength of the first PRS is lower than a preset signal strength threshold, determine that the AI ​​function needs to be deactivated.

[0267] In some embodiments, the AI ​​function deployed in the terminal device is an AI model, which is used to directly locate the terminal device. The terminal device can measure a first PRS to obtain second measurement data, and input the second measurement data into the AI ​​model. The AI ​​model outputs the predicted location information of the terminal device. The terminal device compares the location information predicted by the AI ​​model with the actual location information of the terminal device to determine whether it is necessary to activate the AI ​​function.

[0268] In step S2202, the terminal device sends a stop message to the LMF network element. The stop message is used to instruct the terminal device to stop the AI ​​function positioning.

[0269] In some embodiments, if the terminal device determines to deactivate the AI ​​function deployed on the terminal device, the terminal device sends a stop message to the LMF network element. This stop message instructs the terminal device to stop AI function location. The terminal device sends a stop message to the LMF network element to indicate that it needs to stop AI function location. Correspondingly, the LMF network element receives the stop message from the terminal device and can determine from the stop message that the terminal device has stopped AI function location.

[0270] In some embodiments, the termination message includes second termination reason information, which is used to instruct the terminal device to terminate the AI ​​function positioning.

[0271] In step S2203, the LMF network element stops sending the second auxiliary information to the terminal device; wherein, the second auxiliary information is used by the terminal device to perform AI function positioning.

[0272] In some embodiments, the LMF can suspend sending the second auxiliary information to the terminal device, wherein the second auxiliary information is used by the terminal device to perform AI function positioning. The implementation method of the terminal device performing AI function positioning based on the second auxiliary information can be found in [reference needed]. Figure 2b The relevant details in step S2201 will not be repeated here.

[0273] Since the terminal device suspends AI function positioning, it does not need to measure the first PRS. In this case, the LMF network element can stop sending the second auxiliary information to the terminal device to save signaling overhead.

[0274] Step S2204: The terminal device stops the AI ​​function positioning.

[0275] In some embodiments, stopping AI function positioning in a terminal device means stopping the terminal device from positioning itself based on the AI ​​function deployed in the terminal device. For example, the AI ​​function deployed in the terminal device is an AI model, and the terminal device can stop inputting second measurement data into the AI ​​model, thereby stopping AI function positioning.

[0276] Step S2205: The terminal device stops sending the terminal device's positioning measurement results to the LMF network element. The positioning measurement results are used to locate the terminal device.

[0277] In some embodiments, the AI ​​function deployed in the terminal device is used to assist in the positioning of the terminal device and obtain the positioning measurement result of the terminal device. For example, the AI ​​function deployed in the terminal device is an AI model, which has the ability to output the positioning measurement result of the terminal device based on the second measurement data.

[0278] In some embodiments, the positioning measurement results may include, for example, LOS, NLOS, etc., but are not limited thereto.

[0279] Since the terminal device needs to activate the AI ​​function, the terminal device can stop sending the terminal device's positioning measurement results to the LMF network element, so that the LMF network element stops determining the terminal device's location information based on the terminal device's positioning measurement results.

[0280] Step S2206: The terminal device stops sending its location information to the LMF network element.

[0281] In some embodiments, the AI ​​function deployed in the terminal device is used to directly locate the terminal device and obtain its location information. For example, the AI ​​function deployed in the terminal device is an AI model, which has the ability to output the location information of the terminal device based on second measurement data.

[0282] In some embodiments, the second measurement data may include, for example, channel impulse response, power spectral density, RSRP, RSRQ, etc., obtained by the terminal device measuring the first PRS, but is not limited thereto.

[0283] Since the terminal device needs to activate the AI ​​function, it can stop sending its location information to the LMF network element.

[0284] Step S2207: Update the AI ​​function on the terminal device.

[0285] In some embodiments, the AI ​​function deployed in the terminal device may not meet the positioning requirements of the terminal device, or the positioning performance of the AI ​​function may be poor, so the terminal device may update the AI ​​function.

[0286] In some embodiments, updating AI functions may include at least one of the following: retraining the AI ​​function, fine-tuning the AI ​​function, retraining the AI ​​model (the AI ​​model is used by the terminal device to locate the AI ​​function), fine-tuning the model parameters of the AI ​​model, etc., but not limited to these.

[0287] The communication method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2207. For example, step S2202 may be implemented as an independent embodiment, step S2202 + step S2203 may be implemented as an independent embodiment, step S2202 + step S2204 may be implemented as an independent embodiment, step S2202 + step S2203 + step S2204 may be implemented as an independent embodiment, step S2202 + step S2203 + step S2205 may be implemented as an independent embodiment, step S2202 + step S2203 + step S2206 may be implemented as an independent embodiment, and step S2202 + step S2203 + step S2207 may be implemented as an independent embodiment, but is not limited thereto.

[0288] In some embodiments, steps S2204, S2205, S2206, and S2207 may be executed in an alternate order or simultaneously; steps S2203 and S2204 may be executed in an alternate order or simultaneously; steps S2203 and S2205 may be executed in an alternate order or simultaneously; steps S2203 and S2206 may be executed in an alternate order or simultaneously; and steps S2203 and S2207 may be executed in an alternate order or simultaneously. Steps S2201, S2203, S2204, S2205, S2206, and S2207 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0290] Figure 3 This is an exemplary interaction diagram of the communication method provided in this embodiment. Figure 3 .like Figure 3 As shown, the communication method includes the following steps:

[0291] In step S3101, the terminal device sends a stop message to the LMF network element. The stop message is used to instruct the device to stop acquiring the first measurement data, and / or, the terminal device stops the AI ​​function positioning. The AI ​​function is deployed in the terminal device.

[0292] In some embodiments, the AI ​​function is deployed in a terminal device, and the terminal device can perform AI positioning based on the deployed AI function to determine the location information of the terminal device. In some embodiments, the AI ​​function deployed in the terminal device may also be referred to as one of the following: AI, AI model, ML, ML function, ML model, etc.

[0293] The first measurement data is used to train an AI model, which is deployed in the terminal device and used by the terminal device to locate AI functions.

[0294] For an introduction to the first measurement data, please refer to [link / reference needed]. Figure 2a The relevant details of step S2101 will not be repeated here.

[0295] In some embodiments, if the terminal device needs to acquire first measurement data, the LMF needs to periodically send first auxiliary information to the terminal device, and the terminal device acquires the first measurement data based on the first auxiliary information. In some embodiments, if the terminal device stops acquiring the first measurement data, the terminal device can send a stop message to the LMF network element, which instructs the terminal device to stop acquiring the first measurement data. By sending a stop message to the LMF network element, the terminal device can indicate to the LMF that it no longer needs to acquire the first measurement data. Accordingly, the LMF network element receives the stop message sent by the terminal device and can determine that the terminal device no longer needs to acquire the first measurement data based on the stop message.

[0296] In some embodiments, if a terminal device needs to suspend AI function positioning, it can send a suspension message to the LMF network element. This suspension message instructs the terminal device to suspend AI function positioning. By sending a suspension message to the LMF network element, the terminal device can indicate to the LMF network element that it no longer needs to perform AI function positioning. Correspondingly, the LMF network element receives the suspension message sent by the terminal device and can determine from the suspension message that the terminal device no longer needs to perform AI function positioning.

[0297] In some embodiments, optional implementations of step S3101 can be found in [reference needed]. Figure 2a The optional implementation methods of step S2101, and Figure 2a Other related parts in the embodiments involved will not be described in detail here.

[0298] In some embodiments, optional implementations of step S3101 can be found in [reference needed]. Figure 2b The optional implementation methods of step S2202, and Figure 2b Other related parts in the embodiments involved will not be described in detail here.

[0299] Figure 4 This is an exemplary interaction diagram of the communication method provided in this embodiment. Figure 4 .like Figure 4 As shown, the communication method includes the following steps:

[0300] In step S4101, the LMF network element determines to deactivate the AI ​​function, which is deployed in the terminal device.

[0301] In some embodiments, AI functionality is deployed in a terminal device, which can perform AI positioning based on the deployed AI functionality to determine its location information. In some embodiments, the AI ​​functionality deployed in the terminal device may also be referred to as one of the following: AI, AI model, ML, ML function, ML model, etc. In the following embodiments, for ease of description, AI functionality will be used as an example.

[0302] In some embodiments, the terminal device can directly locate itself based on the AI ​​functionality deployed within it. For example, the terminal device can input relevant measurement data into the AI ​​model deployed within it, and then the AI ​​model can output the location information of the terminal device.

[0303] In some embodiments, the measurement data input to the AI ​​model may include, for example, channel impulse response, power spectral density, RSRP, RSRQ, etc., but are not limited thereto.

[0304] In some embodiments, the terminal device can perform assisted positioning based on AI functions deployed within it. For example, the AI ​​function deployed in the terminal device is an AI model. The terminal device can input corresponding measurement data into the AI ​​model, and then the AI ​​model can output the positioning measurement result of the terminal device. In some embodiments, this positioning measurement result is used to assist in positioning the terminal device. For example, the terminal device can send the positioning measurement result to an LMF network element, and the LMF network element can calculate the location information of the terminal device based on the positioning measurement result.

[0305] In some embodiments, the positioning measurement results may include, for example, LOS, NLOS, etc., but are not limited thereto.

[0306] In some embodiments, the LMF network element can monitor the AI ​​function in a certain way. If the positioning performance of the AI ​​function deteriorates or the AI ​​function fails to meet the positioning requirements of the terminal device, the LMF network element determines that the AI ​​function needs to be activated.

[0307] In some embodiments, the AI ​​function deployed in the terminal device needs to be under certain conditions to be able to locate the terminal device well. If the certain conditions are not met, the positioning performance of the AI ​​function will deteriorate.

[0308] In some embodiments, the terminal device may measure the signal strength of the first PRS and report the signal strength of the first PRS to the LMF network element. If the signal strength of the first PRS is lower than a preset signal strength threshold, the LMF network element determines that the AI ​​function needs to be deactivated.

[0309] In some embodiments, the AI ​​function deployed in the terminal device is an AI model, which is used to directly locate the terminal device. The terminal device can measure a first PRS (Positive Position Scale) to obtain second measurement data, and input the second measurement data into the AI ​​model. The AI ​​model outputs the predicted location information of the terminal device. The terminal device reports the location information predicted by the AI ​​model to the LMF (Local Position Filter) network element. The LMF network element compares the actual location information of its terminal device with the actual location information to determine whether the AI ​​function needs to be activated.

[0310] In step S4102, the LMF network element sends a stop message to the terminal device. The stop message is used to instruct the terminal device to stop performing AI function positioning.

[0311] In some embodiments, if the LMF network element determines to deactivate the AI ​​function deployed in the terminal device, the LMF network element sends a stop message to the terminal device. This stop message instructs the terminal device to stop AI function localization. The LMF network element instructs the terminal device to stop AI function localization by sending a stop message. Correspondingly, the terminal device receives the stop message from the LMF network element and can determine from this message that it needs to stop AI function localization.

[0312] In some embodiments, the termination message includes termination reason information, which is used to instruct the terminal device to terminate AI function positioning, and / or, the AI ​​function does not meet the positioning requirements of the terminal device.

[0313] Step S4103: The terminal device stops the AI ​​function positioning.

[0314] In some embodiments, optional implementations of step S4103 can be found in [reference needed]. Figure 2b Optional implementations of step S2204, and Figure 2b Other related parts in the embodiments involved will not be described in detail here.

[0315] Step S4104: The terminal device stops sending the terminal device's positioning measurement results to the LMF network element. The positioning measurement results are used to locate the terminal device.

[0316] In some embodiments, optional implementations of step S4104 can be found in [reference needed]. Figure 2b The optional implementation methods of step S2205, and Figure 2b Other related parts in the embodiments involved will not be described in detail here.

[0317] Step S4105: The terminal device stops sending its location information to the LMF network element.

[0318] In some embodiments, optional implementations of step S4105 can be found in [reference needed]. Figure 2b Optional implementations of step S2206, and Figure 2b Other related parts in the embodiments involved will not be described in detail here.

[0319] Step S4106: Update the AI ​​function of the terminal device.

[0320] In some embodiments, optional implementations of step S4106 can be found in [reference needed]. Figure 2b Optional implementations of step S2207, and Figure 2b Other related parts in the embodiments involved will not be described in detail here.

For example, step S4102 may be implemented as a standalone embodiment, step S4102 + step S4103 may be implemented as a standalone embodiment, step S4102 + step S4104 may be implemented as a standalone embodiment, step S4102 + step S4103 + step S4104 may be implemented as a standalone embodiment, step S4102 + step S4103 + step S4105 may be implemented as a standalone embodiment, and step S4102 + step S4103 + step S4106 may be implemented as a standalone embodiment, but is not limited thereto.

[0322] In some embodiments, steps S4103, S4104, S4105, and S4106 may be performed in an alternate order or simultaneously. Steps S4101, S4103, S4104, S4105, and S4106 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0325] In step S5101, the LMF network element sends a stop message to the terminal device. The stop message is used to instruct the terminal device to stop performing AI function positioning.

[0326] In some embodiments, the AI ​​function is deployed in a terminal device, and the terminal device can perform AI positioning based on the deployed AI function to determine the location information of the terminal device. In some embodiments, the AI ​​function deployed in the terminal device may also be referred to as one of the following: AI, AI model, ML, ML function, ML model, etc.

[0327] In some embodiments, if an LMF network element needs to suspend AI function positioning, the LMF network element can send a suspension message to the terminal device. This suspension message instructs the terminal device to suspend AI function positioning. By sending a suspension message to the terminal device, the LMF network element can instruct the terminal device to suspend AI function positioning. Correspondingly, the terminal device receives the suspension message sent by the LMF network element and can suspend AI function positioning based on the suspension message.
