[0138] In some embodiments, the updated first model runs successfully, and the terminal sends first information to the network device, wherein the first information is used to indicate that the update of the first model is completed.

[0139] In some embodiments, the network device receives first information sent by the terminal, wherein the first information is used to indicate that the first model update is completed.

[0140] In a possible implementation, the network device is expected to allocate a new model identifier to the updated first model.

[0141] In a possible implementation, the network device allocates a new model identifier to the updated first model according to completion of the updating of the first model.

[0142] In some embodiments, the method further includes: if the updated first model fails to run successfully, the terminal sends second information to the network device, wherein the second information is used to indicate that the update of the first model has failed.

[0143] In some embodiments, the network device receives second information sent by the terminal, wherein the second information is used to indicate that the first model update has failed.

[0144] In a possible implementation, the second information is further used to indicate a reason why the first model update fails.

[0145] In some embodiments, the method may further include: the terminal indicating, to the network device, a model structure of at least one model deployed on the terminal.

[0146] In one possible implementation, indicating to the network device the model structure of at least one model deployed on the terminal may specifically include: sending third information to the network device, wherein the third information includes the model identifier of the at least one model; the network device stores a first correspondence between the model identifier and the model structure, and the third information is used by the network device to determine the model structure corresponding to the model identifier of the at least one model based on the first correspondence.

[0147] In the process of model identification, the terminal or the server associated with the terminal can report the model structure information of each model deployed on the terminal to the network device; the network device can assign a unique model identifier to each model, such as a model ID; further, each terminal can report the identifier of the model deployed on the terminal to the network device through third information, so that the network device can determine the model structure supported by each terminal based on the first correspondence between the model identifier and the model structure.

[0148] In some embodiments, the network device stores a first correspondence between a model identifier and a model structure.

[0150] In particular, the network device can negotiate with the terminal or the server corresponding to the terminal to pre-define a set of common model structures (common model structures), and assign a unique model structure identifier, such as a structure ID, to each common model structure; further, each terminal can report the model structure identifier of the model deployed on the terminal to the network device through the fourth information, so that the network device determines the model structure supported by each terminal based on the second correspondence between the model structure identifier and the model structure.

[0151] In some embodiments, the network device stores a second correspondence between the model structure identifier and the model structure. The network device receives fourth information sent by the terminal, wherein the fourth information includes the model structure identifier of the at least one model; and the network device determines the model structure corresponding to the model structure identifier of the at least one model based on the second correspondence and the fourth information.

[0152] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 to S203. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, step S203 may be implemented as an independent embodiment, and steps S201+S202 may be implemented as independent embodiments, but are not limited thereto.

[0153] In some embodiments, steps S201 , S202 , and S203 may be performed in an interchangeable order or simultaneously.

[0154] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0155] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0156] In some embodiments, step S203 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0157] In some embodiments, reference may be made to other optional embodiments described before or after the description corresponding to FIG. 2 .

[0158] In some embodiments, an artificial intelligence model (AI model, hereinafter referred to as the "model") can be trained by the network side, then transmitted from the network side to the terminal, and then applied by the terminal. After receiving the model, the terminal needs to first perform corresponding processing on the model, such as compiling and quantizing the model. Compilation processing usually refers to the use of a specific compiler, tool chain, and dependent library to convert the model file received by the terminal into executable code that can be run on the terminal. Quantization processing usually refers to the process of converting model parameters represented by floating-point numbers into low-order integers or fixed-point numbers to reduce the memory usage and computational overhead of the model.

[0159] In some embodiments, when a model needs to be updated, the network can first retrain the model using a new data set, then generate a model file corresponding to the updated model, and transmit the model file corresponding to the updated model to the terminal. Furthermore, the terminal can compile, quantize, and perform other processing on the received model file to obtain the updated model. In the above embodiments, when the terminal updates the model, compiling, quantizing, and other processing on the model requires additional processing power.

[0160] In some embodiments, to reduce the processing power requirements of terminals, when updating a model already deployed on a terminal, it is possible to only transmit the model parameters corresponding to the model already deployed on the terminal. However, some technical issues remain, such as how terminals and network devices interact with each other and how network devices learn the model structures supported by each terminal.

[0161] In a first aspect, embodiments of the present disclosure provide a model updating method. Figure 3 is a schematic flow chart illustrating a model updating method according to an embodiment of the present disclosure. The model updating method illustrated in this embodiment can be executed by a terminal.

[0162] In some embodiments, one or more models may be deployed on the terminal. For example, models model#1, model#2, and model#3 may be deployed on the terminal.

[0163] In some embodiments, the model structures of the various models deployed on the terminal may be the same or different. For example, the model structure of model#1 deployed on the terminal is structure#1, and the model structures of model#2 and model#3 deployed on the terminal are structure#2.

[0164] In some embodiments, the first model may be at least one model deployed on the terminal. In one possible implementation, the first model may be one or more models of the at least one model deployed on the terminal that the terminal desires to update. To facilitate a better understanding of the present disclosure by those skilled in the art, the present disclosure is described below using model#1 as the first model as an example.

[0165] As shown in FIG3 , the model updating method may include the following steps:

[0166] In step S301, model parameters for updating a first model sent by a network device are received, wherein the first model is deployed on a terminal.

[0167] In step S302, the model parameters are applied to the model structure of the first model to obtain an updated first model.

[0168] For example, model#1 is deployed on the terminal, and the terminal can receive model parameters sent by the network device for updating model#1; further, the terminal can apply the received model parameters to structure#1 to obtain the updated model#1.

[0169] It should be noted that the embodiment shown in FIG. 3 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0170] The model structure defines the overall framework and components of the model. It can be used to determine the model's basic computational units and data processing flow. It can describe the model's hierarchy, connectivity, and data flow paths. For example, the model structure can include a fully connected neural network, a convolutional neural network, a recurrent neural network, and so on.

[0171] The model structure involved in this disclosure can also be described as a model framework or model architecture, which is not limited in this disclosure.

[0172] Model parameters are variables that need to be optimized during model training. Model parameters can be used to adjust the model's behavior so that it can effectively model and predict input data. For example, model parameters for a neural network model typically include weights and biases. Weights control the strength of connections between neurons, while biases control the offset of activation functions. Model parameters are obtained by iteratively calculating them using an optimization algorithm on training data.

[0173] It should be noted that in the embodiments of the present disclosure, the first model has been deployed on the terminal. It can be considered that during the deployment process, the terminal has compiled the model structure of the first model and applied the initial model parameters to the model structure of the first model. Furthermore, in step S302, the updated model parameters can be applied to the model structure of the first model. Among them, applying the model parameters to the model structure can also be described as loading the model parameters into the model structure, and the present disclosure does not limit this.

[0174] In some embodiments, the terminal may determine, based on an instruction from the network device, whether the network device has model parameters for updating the first model. The network device having model parameters for updating the first model may indicate that, after the terminal applies the initial model parameters of the first model to the model structure of the first model, the model parameters of the first model maintained by the network device are updated, and the terminal has available updates for the model parameters of the first model.

[0175] In a further embodiment, if it is determined that the network device has model parameters for updating the first model, the terminal may receive the model parameters for updating the first model sent by the network device. In one possible implementation, after determining that the network device has model parameters for updating the first model, the terminal may first determine whether to receive the model parameters. If the terminal determines to receive the model parameters, it may then receive the model parameters for updating the first model sent by the network device.

[0176] According to an embodiment of the present disclosure, a terminal can receive model parameters for updating a first model sent by a network device, and apply the received model parameters to the model structure of the first model to obtain an updated first model. Accordingly, when updating a first model that has been deployed on a terminal, the updated first model can be obtained by transmitting the updated model parameters between the terminal and the network device, and the terminal applying the updated model parameters to the model structure of the first model, without the need to transmit the entire model file related to the updated first model between the terminal and the network device, and without the need for the terminal to recompile the model structure of the first model, thereby reducing the amount of data transmitted between the terminal and the network device, reducing the requirements for terminal performance, and saving terminal power consumption.

[0177] Optionally, the network device sends model parameters for updating a first model to the terminal, wherein the first model is deployed on the terminal; the model parameters are used to be applied to the model structure of the first model to obtain an updated first model.

[0178] In some embodiments, the process of updating the deployed first model by the terminal may be triggered by the terminal or by a network device.

[0179] In some embodiments, the terminal may trigger the update of the deployed first model. In this case, before step S301, the method further includes: sending a query request for the first model to the network device, wherein the query request is used to determine whether the network device has model parameters for updating the first model; and receiving a query response for the first model sent by the network device, wherein the query response is used to indicate whether the network device has model parameters for updating the first model.

[0180] For example, the terminal sends a query request for model#1 to the network device so that the network device determines whether there are model parameters for updating model#1; further, the terminal can receive a query response for model#1 sent by the network device; wherein, according to the query response indicating that the network device has model parameters for updating model#1, the terminal can determine that there are available updates for the model parameters of model#1; or, according to the query response indicating that the network device does not have model parameters for updating model#1, the terminal can determine that there are no available updates for the model parameters of model#1.

[0181] In some embodiments, the query request includes at least one of the following: an identifier of a model that the terminal expects to update; and a structure identifier of the model that the terminal expects to update.

[0182] Optionally, the network device stores at least one of the following correspondences: a first correspondence between a model identifier and a model structure; and a second correspondence between a model structure identifier and a model structure.

[0183] For example, if a terminal desires to update model#1, the terminal may send a query request for model#1 to a network device. The query request may include a model identifier "model ID=1" of model#1, so that after receiving the query request, the network device determines, based on the model identifier "model ID=1" included in the query request and the first correspondence between the model identifier and the model structure, that the terminal supports structure#1 corresponding to the model identifier "model ID=1", and determines that the terminal desires to update model parameters related to structure#1.

[0184] For another example, if the terminal expects to update model#1, the terminal may send a query request for model#1 to the network device. The query request may include the model structure identifier "structure ID=1" of structure#1 of model#1, so that after receiving the query request, the network device determines, based on the model structure identifier "structure ID=1" included in the query request and the second correspondence between the model structure identifier and the model structure, that the terminal supports structure#1 corresponding to the model structure identifier "structure ID=1", and determines that the terminal expects to update the model parameters related to structure#1.

[0185] In the above embodiment, when the terminal expects to update the deployed first model, it can actively query the network device whether there is an available update for the first model, and then obtain the model parameters for updating the first model from the network device, so that the terminal can update the first model on demand, saving terminal power consumption.

[0186] Optionally, the network device may receive a query request for the first model sent by the terminal, wherein the query request is used to determine whether the network device has model parameters for updating the first model. The network device may send a query response for the first model to the terminal, wherein the query response is used to indicate whether the network device has model parameters for updating the first model.

[0187] Optionally, the network device may query whether there are model parameters for updating the first model according to the model identifier and / or model structure identifier included in the query request for the first model.

[0188] In some embodiments, the terminal may update the deployed first model by triggering a network device. In this case, before step S301, the method further includes receiving an update notification for the first model sent by the network device, wherein the update notification is used to indicate that a model parameter of the first model has been updated.

[0189] For example, when the network device determines that the model parameters of model#1 are updated, the network device sends an update notification for model#1 to the terminal; in response to receiving the update notification for model#1 sent by the network device, the terminal can determine that there is an available update for the model parameters of model#1.

[0190] In some embodiments, the terminal supports model parameter update capability.

[0191] Optionally, the network device may determine whether the terminal supports the model parameter update capability; in response to the terminal supporting the model parameter update capability, the network device sends an update notification for the first model to the terminal.

[0192] In some possible implementations, the network device may request the terminal to report whether it supports the model parameter update capability; or, the network device may determine whether the terminal supports the model parameter update capability based on the terminal capability information reported by the terminal when accessing the network; or, the network device may obtain the capability information supported by the terminal from the core network to determine whether the terminal supports the model parameter update capability.

[0193] In the above embodiment, when the network device determines that there is an available update for the first model, it can actively notify the terminal so that the terminal can obtain the model parameters for updating the first model from the network device as soon as possible, thereby improving the terminal's update efficiency for the first model.

[0194] In some embodiments, before step S301, the method may further include: receiving configuration information sent by the network device for updating the model parameters of the first model, wherein the configuration information is used to assist the terminal in determining whether to receive the model parameters sent by the network device for updating the first model.

[0195] In some possible implementations, the configuration information may include at least one of the following: computational complexity of the model parameters; storage space required for the model parameters; and usage scenarios of the model parameters.

[0196] For example, the terminal determines that the network device has model parameters for updating model#1, and the terminal can receive configuration information sent by the network device for updating the model parameters of model#1, and determine whether to receive the model parameters sent by the network device for updating model#1 based on the received configuration information.

[0197] In some embodiments, before step S301, the method further includes: determining whether to receive the model parameters based on the network device having model parameters for updating the first model.

[0198] For example, based on the query response to model#1 or the update notification to model#1, the terminal can determine that the network device has model parameters for updating model#1; further, the terminal can determine to receive the model parameters sent by the network device for updating model#1, or the terminal can determine not to receive the model parameters sent by the network device for updating model#1.

[0199] For another example, based on a query response to model#1 or an update notification for model#1, the terminal can determine that the network device has model parameters for updating model#1, and the terminal can receive configuration information sent by the network device for updating the model parameters of model#1 to obtain information such as the computational complexity of the model parameters, the storage space required for the model parameters, and the usage scenarios of the model parameters; further, the terminal can determine whether to receive the model parameters sent by the network device for updating model#1 based on the configuration information.

[0200] Among them, the terminal determines not to receive the model parameters for updating the first model sent by the network device, which can be considered as: the network device is expected not to send the model parameters for updating the first model to the terminal; or, the network device sends the model parameters for updating the first model to the terminal, and the terminal refuses to receive the model parameters for updating the first model sent by the network device; or, the network device sends the model parameters for updating the first model to the terminal, and the terminal does not apply the received model parameters to the model structure of the first model after receiving the model parameters for updating the first model sent by the network device.

[0201] In the above embodiment, when the terminal determines that there is an available update for the first model in the network device, it can determine on its own whether to update the deployed first model, or it can determine on its own whether to update the deployed first model based on the configuration information of the updated model parameters, thereby improving the flexibility of the terminal in updating the model.

[0202] Optionally, the network device may determine whether the terminal receives model parameters for updating the first model.

[0203] In some embodiments, after step S302, the method further includes: when the updated first model runs successfully, sending first information to the network device, wherein the first information is used to indicate that the update of the first model is completed.

[0204] Optionally, the network device receives first information sent by the terminal, wherein the first information is used to indicate that the update of the first model is completed.

[0205] In a possible implementation, the network device is expected to allocate a new model identifier to the updated first model.

[0206] Optionally, the network device assigns a new model identifier to the updated first model according to the completion of the updating of the first model.

[0207] For example, model#1 is deployed on the terminal, and the terminal can receive model parameters sent by the network device for updating model#1; further, the terminal can apply the received model parameters to structure#1 to obtain an updated model#1; if the updated model#1 runs successfully, the terminal can send a first message to the network device to indicate to the network device that the update of model#1 deployed on the terminal has been completed; further, the network device can assign a new model identifier "model ID=4" to the updated model#1.

[0208] In the above embodiment, the terminal determines that the network device has an available update for the model parameters of the first model. After the update is complete, the terminal can provide feedback to the network device via a first message, so that the network device is informed that the terminal has completed the update of the first model deployed by itself. Furthermore, to implement version control, the network device can also assign a new model identifier to the updated first model to distinguish which version of the first model currently deployed on the terminal is.

[0209] In some embodiments, after step S302, the method further includes: if the updated first model fails to run successfully, sending second information to the network device, wherein the second information is used to indicate that the update of the first model has failed.

[0210] Optionally, the network device receives second information sent by the terminal, wherein the second information is used to indicate that the first model update fails.

[0211] In a possible implementation, the second information is further used to indicate a reason why the first model update failed. Specific reasons for the update failure are not particularly limited in this disclosure.

[0212] For example, model#1 is deployed on the terminal, and the terminal can receive model parameters sent by the network device for updating model#1; further, the terminal can apply the received model parameters to structure#1 to obtain an updated model#1; if the updated model#1 fails to run successfully, the terminal can send second information to the network device to indicate to the network device that the update of model#1 deployed on the terminal has failed, and to indicate to the network device the reason for the failure to update model#1 deployed on the terminal.

[0213] In the above embodiment, after the terminal determines that an update for the model parameters of the first model is available on the network device and the update fails, the terminal can provide feedback to the network device via the second message, so that the network device is informed that the terminal has failed to update the first model deployed on the terminal. Furthermore, the terminal can also provide feedback to the network device via the second message regarding the reason for the update failure, so that the network device is informed of the reason for the terminal's failure to update the first model deployed on the terminal, which is beneficial for subsequent attempts to update the first model deployed on the terminal.

[0214] Currently in related technologies, network devices are not aware of the model structures supported by various terminals. Therefore, when the network device determines that model parameters related to a certain model structure are updated, it cannot determine for which terminals there are available model parameter updates.

[0215] In some embodiments, the method may further include: indicating to the network device a model structure of at least one model deployed on the terminal.

[0216] For example, model#1, model#2 and model#3 are deployed on the terminal. The terminal can indicate to the network device that the model structure of model#1 deployed on the terminal is structure#1, and the model structure of model#2 and model#3 deployed on the terminal is structure#2.

[0217] In one possible implementation, indicating to the network device the model structure of at least one model deployed on the terminal may specifically include: sending third information to the network device, wherein the third information includes the model identifier of the at least one model; the network device stores a first correspondence between the model identifier and the model structure, and the third information is used by the network device to determine the model structure corresponding to the model identifier of the at least one model based on the first correspondence.

[0218] In the process of model identification, the terminal or the server associated with the terminal can report the model structure information of each model deployed on the terminal to the network device; the network device can assign a unique model identifier to each model, such as a model ID; further, each terminal can report the identifier of the model deployed on the terminal to the network device through third information, so that the network device can determine the model structure supported by each terminal based on the first correspondence between the model identifier and the model structure.

[0219] For example, the third information sent by terminal A to the network device includes the model identifier "model ID=1" of model#1, the model identifier "model ID=2" of model#2, and the model identifier "model ID=3" of model#3; based on the first correspondence and the third information sent by terminal A, the network device can determine that the model structures supported by terminal A include structure#1 and structure#2. The third information sent by terminal B to the network device includes the model identifier "model ID=1" of model#1; based on the first correspondence and the third information sent by terminal B, the network device can determine that the model structures supported by terminal B include structure#1.

[0220] Optionally, the network device stores a first correspondence between a model identifier and a model structure. The network device receives third information sent by the terminal, wherein the third information includes the model identifier of the at least one model; and the network device determines the model structure corresponding to the model identifier of the at least one model based on the first correspondence and the third information.

[0221] In another possible implementation, indicating to the network device the model structure of at least one model deployed on the terminal may specifically include: sending fourth information to the network device, wherein the fourth information includes the model structure identifier of the at least one model; the network device stores a second correspondence between the model structure identifier and the model structure, and the fourth information is used by the network device to determine the model structure corresponding to the model structure identifier of the at least one model based on the second correspondence.

[0222] In particular, the network device can negotiate with the terminal or the server corresponding to the terminal to pre-define a set of common model structures (common model structures), and assign a unique model structure identifier, such as a structure ID, to each common model structure; further, each terminal can report the model structure identifier of the model deployed on the terminal to the network device through the fourth information, so that the network device determines the model structure supported by each terminal based on the second correspondence between the model structure identifier and the model structure.

[0223] For example, the fourth information sent by terminal A to the network device includes the model structure identifier "structure ID=1" of structure#1 of model#1, and the model structure identifier "structure ID=2" of structure#2 of model#2 or model#3; based on the second correspondence and the fourth information sent by terminal A, the network device can determine that the model structures supported by terminal A include structure#1 and structure#2. The fourth information sent by terminal B to the network device includes the model structure identifier "structure ID=1" of structure#1 of model#1; based on the second correspondence and the fourth information sent by terminal B, the network device can determine that the model structures supported by terminal B include structure#1.

[0224] Optionally, the network device stores a second correspondence between the model structure identifier and the model structure. The network device receives fourth information sent by the terminal, wherein the fourth information includes the model structure identifier of the at least one model; and the network device determines the model structure corresponding to the model structure identifier of the at least one model based on the second correspondence and the fourth information.

[0225] In the above embodiment, the terminal can indicate the model structure of at least one model deployed on the terminal to the network device via the third information or the fourth information, so that the network device knows which model structures are supported by each terminal. This facilitates the network device to determine which terminals have available model parameter updates when model parameters associated with a particular model structure are updated. For example, when the network device determines that a model parameter update associated with structure #1 has occurred, it can proactively notify terminal A and terminal B. However, when the network device determines that a model parameter update associated with structure #2 has occurred, it can proactively notify terminal A without notifying terminal B.

[0226] In a second aspect, embodiments of the present disclosure provide a model updating method. Figure 4 is a schematic flow chart illustrating another model updating method according to an embodiment of the present disclosure. The model updating method illustrated in this embodiment can be executed by a network device.

[0227] As shown in FIG4 , the model updating method may include the following steps:

[0228] In step S401, model parameters for updating a first model are sent to a terminal, wherein the first model is deployed on the terminal; the model parameters are applied to the model structure of the first model to obtain an updated first model.

[0229] For example, the network device may send model parameters for updating model#1 to the terminal, so that the terminal applies the received model parameters to structure#1 to obtain an updated model#1.

[0230] It should be noted that the embodiment shown in FIG. 4 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0231] According to an embodiment of the present disclosure, the network device can send model parameters for updating the first model to the terminal, so that the terminal applies the received model parameters to the model structure of the first model. Accordingly, when updating the first model that has been deployed on the terminal, the updated model parameters can be transmitted between the terminal and the network device, and the terminal applies the updated model parameters to the model structure of the first model, so that the updated first model can be obtained without transmitting the entire model file related to the updated first model between the terminal and the network device, and without the terminal having to recompile the model structure of the first model, thereby reducing the amount of data transmitted between the terminal and the network device, reducing the requirements for terminal performance, and saving terminal power consumption.

[0232] Optionally, the terminal may receive model parameters sent by the network device for updating the first model; further, the terminal may apply the model parameters to the model structure of the first model to obtain an updated first model.

[0233] In some embodiments, the process of updating the deployed first model by the terminal may be triggered by the terminal or by a network device.

[0234] In some embodiments, the terminal may trigger the update of the deployed first model. In this case, before step S401, the method further includes: receiving a query request for the first model sent by the terminal, wherein the query request is used to determine whether the network device has model parameters for updating the first model; and sending a query response for the first model to the terminal, wherein the query response is used to indicate whether the network device has model parameters for updating the first model.

[0235] For example, the network device may receive a query request for model#1 sent by the terminal and determine whether there are model parameters for updating model#1; further, the network device may send a query response for model#1 to the terminal; wherein the query response is used to indicate to the network device that there are model parameters for updating model#1, so that the terminal determines that there are available updates for the model parameters of model#1; or, the query response is used to indicate to the network device that there are no model parameters for updating model#1, so that the terminal determines that there are no available updates for the model parameters of model#1.

[0236] In some embodiments, the query request includes at least one of the following: an identifier of a model that the terminal expects to update; and a structure identifier of the model that the terminal expects to update.

[0237] In some possible implementations, the network device stores at least one of the following correspondences: a first correspondence between a model identifier and a model structure; and a second correspondence between a model structure identifier and a model structure. In this case, the network device can query whether model parameters for updating the first model exist based on the model identifier and / or model structure identifier included in the query request for the first model.

[0238] For example, if a terminal desires to update model#1, the terminal may send a query request for model#1 to a network device, where the query request may include a model identifier "model ID=1" of model#1. After receiving the query request, the network device may determine, based on the model identifier "model ID=1" included in the query request and the first correspondence between the model identifier and the model structure, that the terminal supports structure#1 corresponding to the model identifier "model ID=1" and that the terminal desires to update model parameters related to structure#1.

[0239] For another example, if the terminal expects to update model#1, the terminal may send a query request for model#1 to the network device, where the query request may include the model structure identifier "structure ID=1" of structure#1 of model#1; after receiving the query request, the network device may determine, based on the model structure identifier "structure ID=1" included in the query request and the second correspondence between the model structure identifier and the model structure, that the terminal supports structure#1 corresponding to the model structure identifier "structure ID=1", and that the terminal expects to update the model parameters related to structure#1.

[0240] In the above embodiment, when the terminal expects to update the deployed first model, it can actively query the network device whether there is an available update for the first model, and then obtain the model parameters for updating the first model from the network device, so that the terminal can update the first model on demand, saving terminal power consumption.

[0241] Optionally, the terminal sends a query request for the first model to the network device; further, the terminal receives a query response for the first model sent by the network device.

[0242] In some embodiments, the terminal may update the deployed first model by triggering a network device. In this case, before step S401, the method further includes: sending an update notification for the first model to the terminal, wherein the update notification is used to indicate that model parameters of the first model have been updated.

[0243] For example, when the network device determines that the model parameters of model#1 are updated, the network device sends an update notification for model#1 to the terminal; in response to receiving the update notification for model#1 sent by the network device, the terminal can determine that there is an available update for the model parameters of model#1.

[0244] In some embodiments, the method further includes determining whether the terminal supports model parameter update capability. In this case, sending an update notification for the first model to the terminal includes sending an update notification for the first model to the terminal in response to the terminal supporting the model parameter update capability.

[0245] In some possible implementations, the network device may request the terminal to report whether it supports the model parameter update capability; or, the network device may determine whether the terminal supports the model parameter update capability based on the terminal capability information reported by the terminal when accessing the network; or, the network device may obtain the capability information supported by the terminal from the core network to determine whether the terminal supports the model parameter update capability.

[0246] In the above embodiment, when the network device determines that there is an available update for the first model, it can actively notify the terminal so that the terminal can obtain the model parameters for updating the first model from the network device as soon as possible, thereby improving the terminal's update efficiency for the first model.

[0247] In some embodiments, before step S401, the method further includes: sending configuration information for updating the model parameters of the first model to the terminal, wherein the configuration information is used to assist the terminal in determining whether to receive the model parameters for updating the first model sent by the network device.

[0248] In some possible implementations, the configuration information may include at least one of the following: computational complexity of the model parameters; storage space required for the model parameters; and usage scenarios of the model parameters.

[0249] For example, the network device may send configuration information for updating the model parameters of model#1 to the terminal, so that the terminal determines whether to receive the model parameters for updating model#1 sent by the network device according to the configuration information.

[0250] In some embodiments, before step S401, the method further includes: determining whether the terminal receives the model parameters.

[0251] In one possible implementation, the terminal can determine whether to receive the model parameters for updating the first model sent by the network device based on whether the network device has available updates for the model parameters of the first model and / or the configuration information of the model parameters of the first model sent by the network device.

[0252] Among them, the terminal determines not to receive the model parameters for updating the first model sent by the network device, which can be considered as: the network device is expected not to send the model parameters for updating the first model to the terminal; or, the network device sends the model parameters for updating the first model to the terminal, and the terminal refuses to receive the model parameters for updating the first model sent by the network device; or, the network device sends the model parameters for updating the first model to the terminal, and the terminal does not apply the received model parameters to the model structure of the first model after receiving the model parameters for updating the first model sent by the network device.

[0253] In some embodiments, after step S401, the method further includes: receiving first information sent by the terminal, wherein the first information is used to indicate that the first model update is completed.

[0254] Optionally, the updated first model runs successfully, and the terminal sends first information to the network device, wherein the first information is used to indicate that the update of the first model is completed.

[0255] In a possible implementation, the method further includes: according to completion of the updating of the first model, allocating a new model identifier for the updated first model.

[0256] For example, model#1 is deployed on the terminal, and the terminal can receive model parameters sent by the network device for updating model#1; further, the terminal can apply the received model parameters to structure#1 to obtain an updated model#1; if the updated model#1 runs successfully, the terminal can send a first message to the network device to indicate to the network device that the update of model#1 deployed on the terminal has been completed; further, the network device can assign a new model identifier "model ID=4" to the updated model#1.

[0257] In the above embodiment, the terminal determines that the network device has an available update for the model parameters of the first model. After the update is complete, the terminal can provide feedback to the network device via a first message, so that the network device is informed that the terminal has completed the update of the first model deployed by itself. Furthermore, to implement version control, the network device can also assign a new model identifier to the updated first model to distinguish which version of the first model currently deployed on the terminal is.

[0258] In some embodiments, after step S401, the method further includes: receiving second information sent by the terminal, wherein the second information is used to indicate that the first model update fails.

[0259] Optionally, if the updated first model fails to run successfully, second information is sent to the network device, wherein the second information is used to indicate that the update of the first model has failed.

[0260] In a possible implementation, the second information is further used to indicate a reason why the first model update fails.

[0261] For example, model#1 is deployed on the terminal, and the terminal can receive model parameters sent by the network device for updating model#1; further, the terminal can apply the received model parameters to structure#1 to obtain an updated model#1; if the updated model#1 fails to run successfully, the terminal can send second information to the network device to indicate to the network device that the update of model#1 deployed on the terminal has failed, and to indicate to the network device the reason for the failure to update model#1 deployed on the terminal.

[0262] Currently in related technologies, network devices are not aware of the model structures supported by various terminals. Therefore, when the network device determines that model parameters related to a certain model structure are updated, it cannot determine for which terminals there are available model parameter updates.

[0263] In some embodiments, the method further includes: determining a model structure of at least one model deployed on the terminal according to an instruction of the terminal.

[0264] For example, model#1, model#2 and model#3 are deployed on the terminal. The terminal can indicate to the network device that the model structure of model#1 deployed on the terminal is structure#1, and the model structure of model#2 and model#3 deployed on the terminal is structure#2; according to the instruction of the terminal, the network device can determine that the model structure of model#1 deployed on the terminal is structure#1, and the model structure of model#2 and model#3 deployed on the terminal is structure#2.

[0265] In one possible implementation, the network device stores a first correspondence between a model identifier and a model structure. In this case, determining the model structure of at least one model deployed on the terminal according to an instruction of the terminal includes: receiving third information sent by the terminal, where the third information includes the model identifier of the at least one model; and determining the model structure corresponding to the model identifier of the at least one model according to the first correspondence and the third information.

[0266] In the process of model identification, the terminal or the server associated with the terminal can report the model structure information of each model deployed on the terminal to the network device; the network device can assign a unique model identifier to each model, such as a model ID; further, each terminal can report the identifier of the model deployed on the terminal to the network device through third information, so that the network device can determine the model structure supported by each terminal based on the first correspondence between the model identifier and the model structure.

[0267] For example, the third information sent by terminal A to the network device includes the model identifier "model ID=1" of model#1, the model identifier "model ID=2" of model#2, and the model identifier "model ID=3" of model#3; based on the first correspondence and the third information sent by terminal A, the network device can determine that the model structures supported by terminal A include structure#1 and structure#2. The third information sent by terminal B to the network device includes the model identifier "model ID=1" of model#1; based on the first correspondence and the third information sent by terminal B, the network device can determine that the model structures supported by terminal B include structure#1.

[0268] Optionally, the terminal sends the third information to the network device.

[0269] In another possible implementation, the network device stores a second correspondence between a model structure identifier and a model structure. In this case, indicating the model structure of at least one model deployed on the terminal to the network device includes: receiving fourth information sent by the terminal, where the fourth information includes the model structure identifier of the at least one model; and determining, based on the second correspondence and the fourth information, the model structure corresponding to the model structure identifier of the at least one model.

[0270] In particular, the network device can negotiate with the terminal or the server corresponding to the terminal to pre-define a set of common model structures (common model structures), and assign a unique model structure identifier, such as a structure ID, to each common model structure; further, each terminal can report the model structure identifier of the model deployed on the terminal to the network device through the fourth information, so that the network device determines the model structure supported by each terminal based on the second correspondence between the model structure identifier and the model structure.

[0271] For example, the fourth information sent by terminal A to the network device includes the model structure identifier "structure ID=1" of structure#1 of model#1, and the model structure identifier "structure ID=2" of structure#2 of model#2 or model#3; based on the second correspondence and the fourth information sent by terminal A, the network device can determine that the model structures supported by terminal A include structure#1 and structure#2. The fourth information sent by terminal B to the network device includes the model structure identifier "structure ID=1" of structure#1 of model#1; based on the second correspondence and the fourth information sent by terminal B, the network device can determine that the model structures supported by terminal B include structure#1.

[0272] Optionally, the terminal sends the fourth information to the network device.

[0273] In the above embodiment, the terminal can indicate the model structure of at least one model deployed on the terminal to the network device via the third information or the fourth information, so that the network device knows which model structures are supported by each terminal. This facilitates the network device to determine which terminals have available model parameter updates when model parameters associated with a particular model structure are updated. For example, when the network device determines that a model parameter update associated with structure #1 has occurred, it can proactively notify terminal A and terminal B. However, when the network device determines that a model parameter update associated with structure #2 has occurred, it can proactively notify terminal A without notifying terminal B.
