Network slicing and cell signal reselection analysis and early warning method

The invention discloses a method for reselection analysis and early warning of network slices in combination with cell signals. The method comprises the following steps: S11, a user terminal searches a proper cell according to a cell selection criterion; s12, acquiring historical log data of the connected cells stored on the base station server according to indexes in the cell selection criterion, and classifying the historical log data according to the indexes; s13, the index data of the cells are put into the analysis model for operation, optimal indexes are generated and sorted, and the cells are reselected according to the sequence from high to low; and S14, when no cell conforming to the cell selection standard score exists, network slice template registration is carried out on the user terminal, and a virtual base station is provided to replace the reselected cell. According to the method, a proper cell signal source can be selected through a cell selection criterion and an analysis model, and when no h
