5G-based network connection method and device, electronic equipment and storage medium

The invention provides a 5G-based network connection method and device, electronic equipment and a storage medium. The method comprises the following steps: determining one part of bandwidth from at least two part of bandwidths of a cellular cell as the current part of bandwidth, and carrying out terminal network access; wherein the bandwidth of the cellular cell comprises at least two partial bandwidths which are divided in advance, and the sum of the bandwidths of the partial bandwidths is the bandwidth of the cellular cell; the base station broadcasts a synchronization signal block and a system information block according to the frequency of the partial bandwidth; if it is determined that electromagnetic interference exists in the current part of bandwidth, determining a target part of bandwidth from other parts of bandwidth except the current part of bandwidth according to a synchronization signal block broadcasted by the current part of bandwidth; and switching the current part of bandwidth connected wit
