AI Technical Summary
Technical Problem
When used across regions, eSIM network switching is slow, affecting normal communication, and the existing technology of downloading all configuration files in advance leads to excessive terminal memory usage.
Method used
By periodically acquiring the terminal's location, constructing trajectory vectors, predicting adjacent areas, automatically downloading the target operator's configuration files, and dynamically managing the file storage module, only storing a small number of configuration files.
Benefits of technology
It improves network switching speed, ensures normal eSIM communication, and reduces the memory usage of the terminal.

Abstract
The invention discloses an esim automatic pre-downloading method and device, an esim switching method and device, equipment and a medium, and relates to the technical field of esim network management. When the current first periodic position characterizes that the position of the esim is in the boundary range of the first current area, constructing a trajectory vector; determining candidate areas from the adjacent areas; and when the number of the candidate areas is 1, determining that the candidate areas are target areas, and determining a target operator from a preset candidate operator list corresponding to the target areas. And when the target configuration file of the target operator is not stored in the file storage module, a file downloading request is sent to an SM-DP + server of the target operator, so that pre-downloading of the target configuration file is realized. The target configuration file is downloaded in advance, network switching can be directly carried out based on the target configuration file when the terminal enters the target area subsequently, the switching speed is increased, and communication of the target terminal is guaranteed.
