Abstract: The invention discloses an indoor positioning method and apparatus. The method includes: acquiring current cell signal strength information of a terminal located indoors; determining, according to 3D indoor positioning matching information, horizontal position information and height information of an indoor grid that are corresponding to the current cell signal strength information, where the 3D indoor positioning matching information includes a correspondence between cell signal strength information of the indoor grid and the horizontal position information and the height information of the indoor grid; and determining, according to the horizontal position information and the height information of the indoor grid, a horizontal position at which the terminal is located indoors and a height at which the terminal is located. In this way, high-accuracy 3D indoor positioning can be implemented.

Abstract: A process management method and a related electronic device are provided. According to the method, process data in a volatile memory can be migrated to a non-volatile memory in real time in a running process of a system. When the system is asleep, data in a memory does not need to be packaged and backed up. When the system is woken up or restarted, data does not need to be parsed and reconstructed, to implement quick sleeping and waking up of the system. In addition, even if the system is restarted due to an unexpected power failure, a loss of key data in the memory can be avoided, and a speed of waking up or restarting the system can also be improved.

Abstract: A method for creating a network simulation platform that has a first black box model, includes: obtaining a candidate network performance indicator and feature information related to the candidate network performance indicator, where the feature information related to the candidate network performance indicator refers to a part or all of feature information needed to obtain the candidate network performance indicator; and training a machine learning model to obtain the first black box model, where an output parameter of the first black box model is the candidate network performance indicator, input parameters of the first black box model are the feature information related to the candidate network performance indicator, and the first black box model is used to simulate the candidate network performance indicator. The solutions provided help reduce simulation complexity and are applicable to large-scale network simulation.
