Abstract: An artificial intelligence AI communication method. A first apparatus receives AI model information sent by a second apparatus. The AI model information includes M groups of AI model complexity information corresponding to M AI models. Each of the M groups of AI model complexity information is time and/or energy consumption of executing one of the M AI models in each of N reference AI execution environments, wherein M and N are positive integers. The first apparatus sends feedback information to the second apparatus.

Abstract: In a network handover method disclosed in this application, when an electronic device accesses a first mobile network by using the first SIM card, the electronic device obtains network information of the first mobile network in a process in which the electronic device moves along a first route. When the electronic device predicts, according to the obtained network information of the first mobile network, that an exception is going to occur in the first mobile network, the electronic device accesses the second mobile network by using the second SIM card. In this technical solution, an electronic device having a dual SIM card can be handed over from a first mobile network to a second mobile network in advance when it is predicted that an exception is going to occur in the first mobile network, thereby reducing the possibility of frame freezing or network disconnecting when a user accesses the Internet.

Abstract: This application provides a charging time estimation method and apparatus, and a storage medium. The method includes: obtaining a current temperature of a to-be-charged device and a current state of charge (SOC) of the to-be-charged device in a calculation period, and obtaining a required current of the to-be-charged device based on the current temperature and the current state of charge; and determining a charging current of the to-be-charged device; and obtaining a charging time. The method can be applied to a thermal management system of an electric vehicle or an optimization model of an off-line thermal management strategy. In this method, energy consumption of the thermal management system is estimated in a charging process, so as to resolve a problem that the energy consumption of the thermal management system is not considered in the conventional charging time estimation method, to make the estimated charging time more accurate.
