Terminal working frequency point switching method and device, terminal and storage medium

The embodiment of the invention discloses a terminal working frequency point switching method and device, a terminal and a storage medium, and the method comprises the steps: obtaining a first numberof first frequency point information vectors and a second number of second frequency point information vectors of the terminal, and calculating a first preset number of deviation values so as to update the first frequency point information vectors; classifying the matched first number of first frequency point coverage areas according to a preset detection threshold value and the updated first frequency point information vector; sorting the various first frequency point coverage areas according to a preset priority; selecting a target candidate region from the first frequency point coverage region according to the obtained sorting result and a set region classification rule; and executing a working frequency point switching operation on the target candidate area according to the current switching strategy.
