[0145] In recent years, artificial intelligence (AI) technology has achieved continuous breakthroughs in numerous fields. The continued development of fields such as intelligent voice and computer vision has not only brought a rich variety of applications to smart terminals, but has also found widespread application in education, transportation, home furnishings, healthcare, retail, security, and other fields. This has brought convenience to people's lives while also promoting industrial upgrades across various industries. AI technology is also rapidly intersecting with other disciplines, integrating knowledge from different disciplines while also providing new directions and methods for their development.

[0146] During the 3rd Generation Partnership Project (3GPP) Release 18 phase, a research project on artificial intelligence (AI) technology in the wireless air interface was established within RAN1. This project aims to investigate how to integrate AI technology into the wireless air interface and explore how AI can assist in improving wireless air interface transmission technologies.

[0147] In wireless AI research, application cases of artificial intelligence include:

[0148] -AI-based CSI enhancement;

[0149] -AI-based beam management;

[0150] -AI-based positioning.

[0151] In the embodiment of the present disclosure, when the terminal device deploys an AI model, the terminal carrier needs to perform AI model identification (model identification) with the network side device.

[0152] Model identification can be divided into the following two types:

[0153] -Method 1: The relevant server of the terminal device, such as the server of the terminal reporting manufacturer or the server of the chip manufacturer, performs model identification with the network-side device and reports detailed information of the AI ​​model to the network-side device, such as the application scenario of the AI ​​model, the functions that the AI ​​model can achieve, the data set based on which the AI ​​model is trained, the structure or parameters of the AI ​​model, etc. At the same time, the network-side device will assign an AI model identifier (ID) to the registered model, and the terminal device will report the AI ​​model ID corresponding to the deployed AI model when accessing the network-side device;

[0154] Method 2: The terminal device directly reports detailed information about the deployed AI model, such as the AI ​​model's application scenarios, the functions it can achieve, the dataset characteristics the AI ​​model is trained on, and the AI ​​model's structure or parameters. At the same time, the network-side device assigns an AI model ID to the registered model.

[0155] As the strategy for deploying AI models at terminal devices is adjusted or data distribution changes, the deployed AI models may change, such as updating AI models, adding AI models, deleting AI models, etc. When the AI ​​models at the terminal devices change, how to update the supported AI models to the network-side devices?

[0156] Based on this, embodiments of the present disclosure provide a model update method, a terminal device, and a network device. The terminal device sends a model update message to the network device, wherein the model update message is used to indicate a change in the AI ​​model available to the terminal device. Thus, the terminal device can update the AI ​​model supported by the terminal device to the network device to ensure normal communication.

[0157] FIG2 is an interactive diagram of a model updating method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a model updating method, which includes:

[0158] S21: The terminal device determines that the available AI model has changed.

[0159] In an embodiment of the present disclosure, the terminal device can determine the status of the usable AI model and determine whether the usable AI model has changed.

[0160] It is understandable that the terminal device determines that the usable AI model has changed. This may be determined by the terminal device adjusting the usable AI model it has deployed, or it may be determined based on the instructions of the network side device.

[0161] In some embodiments, terms such as "AI model", "AI function", and "AI algorithm" can be used interchangeably.

[0162] In some embodiments, as the terminal device AI model deployment strategy is adjusted and / or the entire data distribution changes, the terminal device needs to update or retrain the available AI model, and the terminal device may also need to deploy a new available AI model.

[0163] In some embodiments, the AI ​​model that can be used may vary, including at least one of the following:

[0164] Usable AI models become unusable;

[0165] Unavailable AI models become available;

[0166] Added new AI models that can be used;

[0167] The available AI model has been removed.

[0168] In the embodiment of the present disclosure, the change in the usable AI model may be that the usable AI model becomes unusable.

[0169] Exemplarily, a first AI model that can be used by the terminal device becomes unavailable. Optionally, the first AI model can be marked as unavailable.

[0170] In the embodiment of the present disclosure, the change in the available AI model may be that an unavailable AI model becomes available.

[0171] Exemplarily, the second AI model that was unavailable on the terminal device becomes available. Optionally, the second AI model may be marked as available.

[0172] In the embodiment of the present disclosure, the change in the available AI model may be the addition of a new available AI model.

[0173] For example, if the third AI model is not originally deployed in the terminal device and the terminal device newly deploys the third model, the third AI model can be newly available. Optionally, the third AI model can be marked as newly available.

[0174] In the embodiment of the present disclosure, the change in the usable AI model may be that the usable AI model is removed.

[0175] For example, if a fourth AI model is originally deployed in the terminal device, and for some reason the terminal device determines that the fourth AI model is no longer used, the available fourth AI model may be removed. Alternatively, the fourth AI model may be marked as available for removal.

[0176] It should be noted that the above embodiments are not exhaustive and are only illustrations of some embodiments. The above embodiments can be implemented individually or in combination.

[0180] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0181] In some embodiments, the network side device receives a first message sent by the terminal device. When the first message is used to indicate that the artificial intelligence AI model that can be used by the terminal device has changed, the network side device can determine that the artificial intelligence AI model that can be used by the terminal device has changed.

[0182] In some embodiments, the first message is used to indicate that the AI ​​model available for use by the terminal device has changed, and can be used to indicate that the AI ​​model available for use by the terminal device has become unavailable.

[0183] In some embodiments, the first message is used to indicate that an AI model that can be used by the terminal device has changed, and can be used to indicate that an AI model that can be used by the terminal device has been removed.

[0184] In some embodiments, the first message is used to indicate that an AI model that can be used by the terminal device has changed, and can be used to indicate that a new AI model can be added to the terminal device.

[0185] In some embodiments, the first message is used to indicate that an AI model available to the terminal device has changed, and can be used to indicate that an AI model that was unavailable to the terminal device has become available.

[0200] In response to the unavailable AI model becoming available, when the network-side device is accessed again, a model update message is sent to the network-side device;

[0201] In response to the newly available AI model, when the network side device is accessed again, a model update message is sent to the network side device.

[0202] In the disclosed embodiment, the terminal device sends a model update message to the network device at different times based on the different reasons for the change in the available AI model. If the available AI model becomes unavailable, the model update message can be sent to the network device immediately.

When a new available AI model is added, the terminal device can send a model update message to the network side device when accessing the network side device again.

[0206] It is understandable that when an unavailable AI model on a terminal device becomes available, or a new available AI model becomes available, the network device needs to provide an indication based on the information previously reported by the terminal device. The indication provided by the network device is unrelated to whether the unavailable AI model on the terminal device becomes available or whether a new available AI model becomes available. Therefore, when an unavailable AI model becomes available or a new available AI model becomes available, the terminal device can send a model update message to the network device when it reconnects to the network device. This will not affect normal communication between the terminal device and the network device.

In this way, the terminal device can promptly report the situation where the available AI model deployed by the terminal device becomes unavailable, so that the network device can make timely adjustments based on the situation of the AI ​​model deployed by the terminal device, avoid data or configuration errors, and ensure normal communication.

[0288] In the disclosed embodiment, the terminal device sends a model update message to the network device at different times according to the different reasons for the change of the available AI model. If the available AI model is removed, the model update message can be sent to the network device immediately. In this way, the terminal device can promptly report the removal of the available AI model deployed by the terminal device, so that the network device can make timely adjustments based on the situation of the AI ​​model deployed by the terminal device, avoid data or configuration errors, and ensure normal communication.

[0289] In the embodiment of the present disclosure, the terminal device sends a model update message to the network side device at different times according to the different reasons for the change of the available AI model. When an unavailable AI model becomes available, the terminal device can send a model update message to the network side device when accessing the network side device again.

[0290] In the embodiment of the present disclosure, the terminal device sends a model update message to the network side device at different times according to the different reasons for the change of the available AI model. When a new available AI model is added, the terminal device can send a model update message to the network side device when accessing the network side device again.

[0291] It is understandable that when an unavailable AI model on a terminal device becomes available, or a new available AI model becomes available, the network device needs to provide an indication based on the information previously reported by the terminal device. The indication provided by the network device is unrelated to whether the unavailable AI model on the terminal device becomes available or whether a new available AI model becomes available. Therefore, when an unavailable AI model becomes available or a new available AI model becomes available, the terminal device can send a model update message to the network device when it reconnects to the network device. This will not affect normal communication between the terminal device and the network device.

[0292] It should be noted that the above embodiments are not exhaustive and are only illustrations of some embodiments. The above embodiments can be implemented individually or in combination. The above embodiments are only for illustration and are not intended to be a specific limitation on the scope of protection of the embodiments of the present disclosure.

[0296] In response to the usable AI model becoming unavailable, the system switches to an idle state and sends a model update message to the network device when reconnecting to the network device.

[0297] In response to the removal of the usable AI model, it switches to the idle state, and when reconnecting to the network side device, sends a model update message to the network side device.

[0298] In the disclosed embodiment, the terminal device sends a model update message to the network device in different ways according to the different reasons for the change of the available AI model. In the case that the available AI model is removed, the model update message can be sent directly to the network device in the connected state. In this way, the terminal device can promptly report the removal of the available AI model deployed by the terminal device, so that the network device can make timely adjustments based on the situation of the AI ​​model deployed by the terminal device, avoid data or configuration errors, and ensure normal communication.

[0300] It is understandable that in some scenarios, the usable AI model is removed or becomes unavailable, and the AI ​​model needs to be replaced immediately, which requires the network-side device to know or re-specify. At this time, the terminal device can send a model update message directly to the network-side device in the connected state.

[0301] In other scenarios, the available AI model is removed or becomes unavailable, and a replacement AI model may be available. The terminal device does not need to send it immediately, but can switch to the idle state. When it reconnects to the network side device, it sends a model update message to the network side device.

[0302] In the embodiment of the present disclosure, the terminal device sends a model update message to the network side device in different ways according to the different reasons for the change of the available AI model.

[0431] It should be noted that the above embodiments are not exhaustive and are only illustrations of some embodiments. The above embodiments can be implemented individually or in combination. The above embodiments are only for illustration and are not intended to be a specific limitation on the scope of protection of the embodiments of the present disclosure.

[0432] By implementing the embodiments of the present disclosure, the network device receives a model update message from the terminal device, where the model update message is used to indicate a change in the AI ​​model available to the terminal device. As a result, the network device can update the AI ​​model supported by the terminal device to ensure normal communication.

[0433] To facilitate understanding of the embodiments of the present disclosure, an exemplary embodiment is provided.

[0434] In an exemplary embodiment, the terminal device may change the supported AI model or AI function to the network side device.

[0435] In some embodiments, in response to a change in an available AI model or AI function, the terminal device performs an update operation on the network-side device. The change in the available AI model or AI function on the terminal side includes that an AI model or AI function that was originally available on the terminal side is unavailable, or that an AI model or AI function that was originally unavailable on the terminal side becomes available, or that an AI model / function that was originally unsupported or not deployed has been successfully deployed on the terminal side.

[0436] When the reasons for the occurrence of the AI ​​model or AI function available on the terminal side are different, the update operation performed on the terminal side is different. For example, when the terminal side model becomes unavailable, the terminal side performs operation A, and when the terminal side AI model or function becomes available from unavailable, the terminal side performs operation B.

[0437] In some embodiments, the update operation performed on the terminal side is different and includes at least one of the following:

[0438] - The time it takes for the terminal to execute an update after an update occurs varies. For example, if an AI model on the terminal becomes unavailable, the terminal immediately sends a message indicating the model is unavailable. When more AI models are available on the terminal, the terminal can initiate an update when it reconnects to the network.

[0439] - The update steps are different: When the model on the terminal side becomes unavailable due to performance degradation, the terminal directly initiates an update request to the network in the connected state. When the AI ​​model on the terminal side is removed, the terminal needs to return to the idle state, reconnect to the network, and then update the supported AI model or AI function.

[0440] - The target network node of the update message is different. For example, when the AI ​​model is unavailable due to the terminal's performance degradation or temporary limited computing resources, the terminal only sends the update information to the base station. When the AI ​​model or AI function supported by the terminal is removed, the terminal needs to send an update request to the core network node such as AMF.

[0441] In some embodiments, the update message initiated by the terminal device to the network device includes the following options:

[0442] - Option 1: The update message only contains the AI ​​functions or AI models that have changed. For example, if AI model A becomes unavailable, the update message only contains the information that the model AI is unavailable. Or if model B is added to the available AI models of the terminal, the terminal will report the update information that model B has become available.

[0443] -Option 2: The update message only contains the currently available AI functions or AI models. For example, if the previously available AI models are A, B, and C, then when model A becomes unavailable, the update message only reports the available models B and C. Similarly, when model D becomes available, the update message contains the available models A, B, C, and D.

[0444] In some embodiments, when the reasons for the AI ​​model update on the terminal side are different, the update information included is different. For example, when the terminal updates an unavailable model, option 1 in (4) is used. When the terminal model adds an available model, option 2 in (4) is used.

[0445] It should be noted that the relevant descriptions in the exemplary embodiments have been described in detail in the embodiments of Figures 2 to 4. For details, please refer to the relevant descriptions of Figures 2 to 4, and no further details will be given here.
