[0182] The following is a brief explanation of the relevant concepts mentioned in this disclosure.

[0183] Model recognition

[0184] For model identification of UE-side models or UE-part of two-sided models, the following methods can be included:

[0185] Type A: Models that are not identified by the network side (if applicable) and the UE side (if applicable) through air interface signaling;

[0186] The model identification process can assign a model ID, which can be used in the air interface signaling after model identification.

[0187] Type B: Model identification is performed via air interface signaling;

[0188] This type can be further subdivided into:

[0189] Type B1: The UE initiates the model recognition process, and the network assists in the remaining steps of model recognition (if any).

[0190] During the model recognition process, a model ID can be assigned to each model.

[0191] Type B2, the network initiates the model recognition process, and the UE responds to the remaining steps of the model recognition (if any) (if applicable);

[0192] During the model recognition process, a model ID can be assigned to each model.

[0193] The embodiments of this disclosure are described below with reference to the accompanying drawings. The model recognition method, apparatus, terminal, and network equipment provided in the embodiments of this disclosure can be applied to wireless communication systems. This wireless communication system can be a system employing fifth-generation (5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art will understand that the 5G New Radio (NR) system is merely an example and not intended to be limiting.

[0194] Referring to Figure 1, which is a structural diagram of a network system applicable to an embodiment of this disclosure, the system includes a user terminal 11 and a base station 12. The user terminal 11 can be a user equipment (UE), such as a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), or wearable device. It should be noted that the specific type of user terminal 11 is not limited in this embodiment. The base station 12 can be a 5G or later version base station (e.g., a next-generation Node B (gNB), 5G NR NB), or a base station in other communication systems, also referred to as a Node B. It should be noted that this embodiment only uses a 5G base station as an example, but the specific type of base station 12 is not limited.

[0195] This disclosure provides a model recognition method, apparatus, terminal, and network device to solve the problem that when a terminal initializes and performs a model recognition process through the air interface to the network side, different terminals perform model recognition for the same model to the network side, resulting in redundant model recognition processes.

[0196] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0197] As shown in Figure 2, this embodiment of the present disclosure provides a model recognition method, executed by a terminal, including:

[0198] Step S201: If at least one first model does not belong to the model set, send the model identification information of the at least one first model to the network device; or

[0199] Upon receiving a model recognition request for at least one first model from a network device, the system sends model recognition information for the at least one first model to the network device.

[0200] The first model is a model generated, downloaded, or obtained by the terminal, and the model set is used to indicate at least one model that the network device has performed model recognition on.

[0201] In some embodiments, the model generated, downloaded, or obtained by the terminal can be understood as a model obtained by the terminal. This model can be a new model, i.e., a model that has not been recognized by the network side, or an updated model, i.e., a model that has been recognized by the network side and then the terminal obtains an updated version of the model.

[0202] It should be noted that, in this embodiment of the present disclosure, when at least one model obtained by the terminal does not belong to at least one model that the network device has already performed model recognition on, the terminal sends model recognition information to the network device, or when the network device sends a model recognition request for at least one model obtained by the terminal, the terminal sends model recognition information to the network device. This allows the network device to perform model recognition only for unrecognized models, which avoids the problem of redundant model recognition processes caused by different terminals performing model recognition on the network side for the same model, thereby reducing signaling overhead.

[0203] In some embodiments, the network devices mentioned in this disclosure may be access network side devices (e.g., base stations), operations, administration and maintenance (OAM) devices, over-the-top servers (OTT servers), core network side devices (e.g., location management functions (LMF)), etc.

[0220] A16. Model parameter information;

[0221] In some embodiments, the model parameter information includes parameters such as the model weights.

[0222] A17. Model version information.

[0223] In some embodiments, this disclosure provides two methods for model recognition:

[0224] Implementation Method 1: The terminal can determine at least part of whether the obtained model belongs to the identified models. This method corresponds to the process of sending the model identification information of the at least one first model to the network device when at least one first model does not belong to the model set.

[0225] In some embodiments, at least a partial determination can be understood to include one of the following:

[0226] The terminal can determine for itself whether the acquired model belongs to the identified model;

[0227] The terminal can only make judgments based on the model identification information.

[0228] Implementation Method 2: The network device determines whether the model obtained by the terminal belongs to the identified model. This method corresponds to the process of sending the model identification information of the at least one first model to the network device when a model identification request for at least one first model is received from the network device.

[0229] The specific implementation of the embodiments of this disclosure will be described in detail below from the perspectives of these two different implementation methods.

[0230] Implementation Method 1

[0231] In some embodiments, under one implementation, before sending the model identification information of the at least one first model to the network device when at least one first model does not belong to the model set, the method further includes:

[0232] The system receives first information sent by a network device. The first information is used to indicate a model set. The first information includes at least one of the following: model identification information of the models in the model set, and model version information of the models in the model set.

[0233] In other words, for model identification information, each identified model will have a corresponding model identification information; for model version information, each identified model will have a corresponding model version information.

[0234] In some embodiments, the model set mentioned in this disclosure can be understood as a set of model identification information corresponding to the identified models, or the model set can be understood as a set of model identification information and model version information corresponding to the identified models.

[0235] It should be noted that in this case, the network device needs to first send the identified models to the terminal to inform the terminal which models have been identified on the network side. In some embodiments, the network side may only notify the terminal of the model identification information of the identified models. In this case, the terminal can only determine whether the obtained model is an identified model based on the model identification information. In some embodiments, since the same model may have different versions with updates, the network device may also notify the terminal of both the model identification information and the model version information of the identified models. In this case, the terminal can determine whether the obtained model is an identified model based on the model identification information, or it can determine whether the obtained model is an identified model based on both the model identification information and the model version information.

[0236] In some embodiments, one implementation of receiving the first information sent by the network device includes:

[0237] Receive target signaling sent by a network device, wherein the target signaling includes first information;

[0238] The target signaling includes at least one of the following:

[0239] B11, Broadcast signaling;

[0240] For example, network devices can notify terminals of initial information through system information broadcasting.

[0241] B12, Special Signaling;

[0242] In some embodiments, the dedicated signaling may include, but is not limited to, at least one of the following: Radio Resource Control (RRC) signaling, Medium Access Control Control Element (MAC CE), and Downlink Control Information (DCI).

[0243] B13. Paging signaling;

[0244] This method can be understood as the network device notifying the terminal of the first information through paging.

[0245] It should be noted that after the terminal obtains the first model, it needs to determine whether the first model belongs to the model set. In some embodiments, under one implementation, the method further includes at least one of the following:

[0246] B21. If the model identifier information of the at least one first model does not exist in the model set, it is determined that the at least one first model does not belong to the model set;

[0247] In some embodiments, the absence of model identification information in the model set can be understood as the model identification information not belonging to the model set, while the presence of model identification information in the model set can be understood as the model identification information belonging to the model set.

[0248] It should be noted that in this case, the terminal makes a judgment based solely on the model identification information. If the model identification information corresponding to a certain first model does not exist in the model set, then the first model does not belong to the model set, that is, the first model is an unidentified model, and the terminal needs to send the model identification information of the first model to the network device. If the model identification information corresponding to a certain first model exists in the model set, then the model belongs to the model set, that is, the model is an identified model, and the terminal does not need to send the model identification information of the first model to the network device.

[0249] It should be noted that this situation usually applies when the obtained model is a new model.

[0250] B22. If the model identifier information of the at least one first model exists in the model set, and the model version information of the at least one first model does not exist in the model set, then it is determined that the at least one first model does not belong to the model set.

[0251] In some embodiments, the absence of model version information in the model set can be understood as the model version information not belonging to the model set, while the presence of model version information in the model set can be understood as the model version information belonging to the model set.

[0252] It should be noted that in this case, the terminal needs to make a judgment based on both the model identification information and the model version information. If the model identification information of the first model exists in the model set but the model version information of the first model does not exist in the model set, then the model does not belong to the model set, that is, the version of the first model is an unidentified model version, and the terminal needs to send the model identification information of the first model to the network device. If the model identification information exists in the model set and the model version information of the first model exists in the model set, then the first model belongs to the model set, that is, the first model is an identified model, and the terminal does not need to send the model identification information of the first model to the network device.

[0253] It should be noted that this situation usually applies when the obtained model is an updated model.

[0254] In some embodiments, if the terminal determines that the model identification information of the first model does not exist in the model set, the terminal can directly determine that the first model is an unidentified model and send the model identification information to the network device.

[0255] In some embodiments, the method further includes:

[0256] A third notification message is sent to the network device, the third notification message including an indication of whether the at least one first model is a model update.

[0257] It should be noted that if the model identification information of the one or more first models exists in the model set, but the model version information of the one or more first models does not exist in the model set, it indicates that the version of the one or more first models has not been identified. In this case, the terminal can send a third notification message to the network device to notify the one or more first models that they are being updated, i.e., the one or more first models are models that are being updated.

[0258] In some embodiments, the terminal may include model version information in the model identification information sent, or the terminal may send the model version information of the first model to the network device through additional signaling.

[0259] B23. If the model identification information of the at least one first model exists in the model set, determine that the at least one first model does not belong to the model set according to the request or instruction of the network device;

[0260] In some embodiments, if the terminal determines that the model identification information of the first model exists in the model set, the terminal cannot determine whether the first model is an identified model. In some embodiments, the network side also needs to make a judgment based on the model version information. After the network device makes the judgment, it will send a request or instruction to the terminal. Based on the request or instruction of the network device, the terminal can know which models are unidentified and only send the model identification information of the unidentified models to the network device.

[0261] It should be noted that this situation usually applies when the obtained model is an updated model.

[0262] In some embodiments, if the terminal determines that the model identification information of the first model does not exist in the model set, the terminal can directly determine that the first model is an unidentified model and send the model identification information to the network device.

[0263] In some embodiments, the method further includes:

[0264] Send a second notification message to the network device, the second notification message including model identification information and model version information of the at least one first model;

[0265] The terminal receives third information sent by a network device, the third information being used to request the terminal to send model identification information of at least one first model or to indicate that the first model is not identified.

[0266] It should be noted that the specific implementation of this process is as follows: When the terminal determines that the model identification information of the first model exists in the model set, the terminal needs the network device to send a second notification message to notify the newly obtained model whose model identification information exists in the model set, along with its corresponding model identification information and model version information. Based on the second notification message, the network device determines whether the model version information of the newly obtained model whose model identification information exists in the model set exists in the model set. If it exists in the model set, it means that the model is an identified model, and the network device does not respond to the terminal or responds to the terminal that model identification is not required (for example, sending an indication message to the terminal, which instructs the terminal not to perform model identification of the first model). If it does not exist in the model set, it means that the model is an unidentified model, and the network device sends a third message to the terminal, which may include the model identification information and model version information of the unidentified model. When the terminal receives the third message, it sends the third message to the network device requesting or indicating the model identification information of the first model.

[0267] B24. If the model identification information of the at least one first model exists in the model set, it is determined that the at least one first model does not belong to the model set;

[0268] In some embodiments, if the terminal determines that the model identification information of the first model exists in the model set, the terminal cannot determine whether the first model is an identified model. In some embodiments, the network side also needs to make a judgment based on the model version information. In order to reduce signaling overhead, the terminal can directly determine that the first model does not belong to the model set in this case, and send the model identification information of the model to the network device. The network device makes a judgment based on the received model identification information. If the received model version of the first model has been identified, the model identification information of the first model is discarded. If the received model version of the first model has not been identified, the model identification information of the first model is stored.

[0269] It should be noted that this situation usually applies when the obtained model is an updated model.

[0270] In some embodiments, if the terminal determines that the model identification information of the first model does not exist in the model set, the terminal can directly determine that the first model is an unidentified model and send the model identification information to the network device.

[0271] Implementation Method Two

[0272] In some embodiments, under one implementation, before sending model identification information of the at least one first model to the network device upon receiving a model identification request for at least one first model from the network device, the method further includes:

[0273] Send second information to the network device, the second information including: model identification information of the first model and / or model version information of the first model.

[0274] It should be noted that in this scenario, the terminal needs to first send the acquired models to the network device to inform the network side which new models have been acquired. In some embodiments, the terminal may send the model identification information and / or model version information corresponding to multiple newly acquired models to the network device at once, or it may send only the model identification information and / or model version information of one newly acquired model to the network device at a time. In some embodiments, the terminal may only notify the network device of the model identification information of the newly acquired models. In this case, the network device can only determine whether the newly acquired model is an already identified model based on the model identification information. In some embodiments, since the same model may have different versions with updates, the terminal may also notify the network device of both the model identification information and the model version information of the acquired models. In this case, the network device can determine whether the newly acquired model is an already identified model based on the model identification information, or it can determine whether the newly acquired model is an already identified model based on both the model identification information and the model version information.

[0275] It should be noted that in this implementation method, the terminal only sends information to the network device once, which can reduce the signaling interaction process between the terminal and the network device and reduce signaling overhead.

[0276] In some embodiments, the terminal mentioned in this disclosure satisfies at least one of the following:

[0277] C11. A terminal that receives a first notification message sent by a network device, wherein the first notification message is used to notify the terminal that it needs to perform the identification of a first model;

[0278] In some embodiments, this situation can be understood as the terminal being a terminal configured by a network device, that is, the network device needs to first determine which terminals need to perform newly acquired model recognition, and then notify the corresponding terminals; in some embodiments, the network device determines whether the terminal needs to perform model recognition based on a second condition; if the terminal needs to perform model recognition, a first notification message is sent to the terminal, the first notification message being used to notify the terminal that it needs to perform the recognition of the first model.

[0279] The second condition includes at least one of the following:

[0280] C111. Does the terminal support the target characteristics, which include, but are not limited to, at least one of the following: positioning, beam management, and channel state information feedback;

[0281] In some embodiments, whether the terminal supports the target feature may include at least one of the following:

[0282] It only indicates whether the terminal supports a certain feature. For example, a terminal that supports the positioning feature can perform model recognition of the first model related to positioning.

[0283] This can indicate whether the terminal supports using the first model. If the terminal supports using AI or ML models in the positioning features and the terminal supports using the first model, then the terminal can perform model recognition of the first model.

[0284] This indicates whether the terminal supports using an AI model or an ML model for the target feature corresponding to the first model. If the terminal supports using an AI model or an ML model for the location feature, it can still perform model recognition for the first model, even if it does not support using the first model. The first model is the model used for the location feature. The target feature here can be a use case, a sub-use case, a feature / feature group (AI / ML-enabled Feature / FG), or a functionality, etc.

[0285] C112. Whether the terminal is interested in the first model. For example, the terminal can report its preference for model recognition, and the network can select the terminal to perform model recognition based on the terminal's reported preference for model recognition.

[0286] C113. Whether the terminal is a contracted terminal, similar to user consent for Minimization of Drive Tests (MDT);

[0287] C114. Does the target characteristic of the terminal meet the requirements? The target characteristic includes, but is not limited to, at least one of the following: traffic volume, throughput, and transmission rate.

[0288] In some embodiments, the terminals that the network device determines need to perform model recognition may be randomly selected. This also includes situations where the network device determines that all terminals need to perform model recognition and instructs each terminal accordingly.

[0289] In some embodiments, the first notification information may be sent to the terminal in at least one of the following ways:

[0290] First notification information is sent to the corresponding terminal via dedicated signaling, such as RRC signaling, MAC CE, DCI, etc.

[0291] The first notification information is sent to the corresponding terminal via paging signaling;

[0292] The first notification information is sent to the corresponding terminal via broadcast signaling.

[0293] C12, A terminal that meets the first condition;

[0294] It should be noted that in this case, the terminal determines on its own whether to recognize the newly acquired model; in some embodiments, the first condition includes at least one of the following:

[0295] C121. A terminal that supports target characteristics, wherein the target characteristics include at least one of the following: positioning, beam management, and channel state information feedback;

[0296] In some embodiments, the terminal supporting the target feature may include at least one of the following:

[0297] Terminals that support certain features, such as terminals that support positioning features, can perform model recognition of the first positioning-related model.

[0298] Terminals that support the use of the first model, such as terminals that support the use of AI or ML models in positioning features and terminals that support the use of the first model, can perform model recognition of the first model.

[0299] Terminals that support the use of AI or ML models for the target features corresponding to the first model can perform model recognition for the first model, even if the terminal does not support the use of the first model, if the terminal supports the use of AI or ML models for the positioning features. The first model is the model used for the positioning features. The target features here can be use cases, sub-use cases, features / feature groups (AI / ML-enabled Features / FGs), or functions, etc.

[0300] C122. For terminals interested in the first model, and for terminals that like model recognition, once a model is obtained, a model recognition process can be initiated for that model.

[0301] C123, Contract Terminal, similar to user consent in MDT;

[0302] C124. A terminal that meets the target characteristics requirements, wherein the target characteristics include at least one of the following: traffic volume, throughput, and transmission rate.

[0303] C13, Any terminal;

[0304] This situation can be understood as all terminals that access the network device, register with the network device, and / or have a connection with the network device need to execute the model recognition method of the present disclosure embodiments.

[0305] It should also be noted that a terminal may perform model recognition within its own capabilities, or it may perform model recognition outside its own capabilities. For example, even if a terminal's capabilities do not support positioning, it may still be able to perform model recognition of positioning-related models.

[0306] The following examples illustrate the specific application of this disclosure embodiment, using both the downloaded model as a new model and the updated model as examples.

[0307] Application Scenario 1: The terminal determines whether the new model is an already identified model.

[0308] As shown in Figure 3, the specific implementation process includes the following:

[0309] Step 31: The network device sends first information to the terminal, the first information including model identification information of at least one model that has undergone model recognition;

[0310] In some embodiments, the network device notifies the user in one or more of the following ways:

[0311] Network devices broadcast recognized models, such as through system information broadcasting;

[0312] Network devices send the identified model information to the terminal that needs to perform model identification via dedicated signaling, such as RRC, MAC CE, DCI, etc.

[0313] Network devices send the identified model information to the terminal that needs to perform model recognition via paging.

[0314] Step 32: When a new model is downloaded on the terminal, the terminal determines whether the new model is an already recognized model based on the first information. If it is an already recognized model, the terminal ends the model recognition process. If it is an unrecognized model, the terminal executes step 33.

[0315] Step 33: The terminal determines that the new model is an unrecognized model and sends the model recognition information of the new model to the network device;

[0316] In some embodiments, the model identification information includes one or more of the following:

[0317] Model identification information, such as model id, can be a global model id or a local model id;

[0318] Meta info, such as vendor information, model performance metrics, etc.

[0319] Condition information, such as the corresponding configuration information;

[0320] Additional condition information, such as cell identification information, may be included in the meta info.

[0321] Model structure information;

[0322] Model parameter information.

[0323] Step 34: After receiving the model recognition information sent by the terminal, the network device stores the model recognition information;

[0324] In some embodiments, the network device may also update the already identified model information to the terminal that needs to perform model recognition.

[0325] It should be noted that if there are multiple new models that need to be identified on the terminal side, the terminal can trigger a model identification process once, that is, send model identification information once, or it can trigger multiple model identification processes separately, that is, send model identification information multiple times.

[0326] Application Scenario 2: The terminal determines whether the updated model is an already identified model.

[0327] For this application scenario, please refer to Application Scenario 1. When the model obtained by the terminal is an existing model on the network, i.e., an updated model, meaning the model identification information is the same, the terminal has the following different implementation methods:

[0328] Method 1: When a network device notifies a terminal that needs or can perform model recognition of a model that it has already recognized, the network device may carry model version information in addition to model identification information (i.e., the first information in step 31 of application scenario 1 also includes model version information). When a terminal has a new model that needs to be recognized, if the model is an updated version of a previous model, that is, the terminal determines that the model identification information of the new model is the same as that of the model notified by the network, but the version information is different, the terminal sends the model recognition information of the new model to the network device, and may optionally carry the model version information of the new version or carry an indication information indicating that the model is updated to the network device, so that the network device can replace or store (add) the model recognition information; if the model identification information and model version information of the model are the same as the model information notified by the network device, the terminal does not perform the model recognition process for this model.

[0329] Method 2: When a new model needs to be identified, if the terminal determines that the model identification information of the new model is the same as that of the model notified by the network device, i.e., the model has already been identified, the terminal will send a second notification message to the network device. The second notification message carries the corresponding model version information of the new model. If the network device receives the model version information sent by the terminal and finds that it is consistent with the model version information on the current network device side, then the network device will not respond to the terminal or the network device will respond to the terminal that model identification is not required (e.g., send an indication message to the terminal). If the network device finds that it is a model update, then the network device will send a third message to request the terminal to send model identification information or indicate that the model has not been identified. The terminal will report the model identification information to the network device based on the network's request or indication.

[0330] Method 3: Based on Method 2, when the terminal sends the model version information, it also sends the model identification information of this model to the network device. If the network device finds that the model version information is consistent, it discards the model identification information. If it finds that it is a model update, it replaces or stores (adds) the model identification information.

[0331] Application Scenario 3: Network devices determine whether a new model is an already identified model.

[0332] As shown in Figure 4, the specific implementation process includes the following:

[0333] Step 41: Download the new model to the terminal;

[0334] Step 42: The terminal sends second information to the network device, which includes model identification information of the new model;

[0335] If there are multiple models that need to be identified on the terminal side, the terminal can trigger a process once to send the identification information of all models that need to be identified to the network, i.e., send the second information once. Alternatively, the terminal can trigger multiple model identification processes to send the model identification information to the network device separately, i.e., send the second information multiple times.

[0336] Step 43: Based on the second information, the network device determines whether to request the terminal to perform model recognition. If it requests the terminal to perform model recognition, then proceed to step 44; otherwise, the network device does not respond to the terminal.

[0337] Step 44: The network device determines that the requesting terminal is performing model recognition and sends a model recognition request to the terminal, which includes model identification information.

[0338] If the terminal sends all the model identification information that needs to be identified to the network device at once, then the network device can also send model identification information of multiple models to request model identification information of multiple models when sending model identification requests.

[0339] Step 45: In response to the network device's model recognition request, the terminal sends the corresponding model recognition information to the network device.

[0340] If a network device requests model recognition information for multiple models at once, the terminal can report the model recognition information for multiple models to the network device at the same time.

[0341] Step 46: The network device receives the model recognition information sent by the terminal and stores the model recognition information.

[0342] Application Scenario 4: Network devices determine whether the updated model is an identified model.

[0343] This application scenario can be found in Application Scenario 3. The difference is that when the terminal has a new model that needs to be identified, it can send the model version information of this model to the network device when sending the model identification information (that is, the second information in step 42 of Application Scenario 3 also carries the model version information). The network device can determine whether to request the terminal to report the model identification information of this model based on the model version information. If the network device finds that the model identification information of this model already exists (that is, this model has already been identified), but the model version information of this model stored in the network device is different from the model version information of this model reported by the terminal, it can be considered as a model update, and the network can request the terminal to report the new version of the model identification information.

[0344] It should be noted that at least one embodiment of this disclosure can avoid redundant model recognition processes and reduce air interface signaling overhead.
