Abstract: An encrypted model file is acquired by encrypting at least a part of model information in an original model file. The original model file describes a target neural network model. A model program code is generated according to the encrypted model file. The model program code describes the target neural network model. An installation package for installing an application (APP) is sent to a User Equipment (UE) based on a request sent by the UE. The installation package includes the model program code.

Abstract: A method for remote assistance is provided. The method includes: receiving a remote assistance file sent by a controlling terminal, the remote assistance file containing a script file generated by the controlling terminal based on user operation; determining whether the script file is compatible to the controlled terminal; and if the script file is compatible to the controlled terminal, executing the script file to perform the user operation corresponding to the script file. Thereby, by transmitting a script file generated based on user operation between the controlled terminal and the controlling terminal, remote assistance can be performed more conveniently and user experience can be improved.
