The invention discloses a network automatic switching method which comprises a step of presetting the corresponding relation among a first network type, a second network types and a use location, a step of obtaining the position information of communication equipment in real time, a step of comparing the position information and a use position stored in advance, and determining the network type corresponding to the use position if the distance difference between the position information and the use position stored in advance is in a preset distance threshold, a step of checking the connected network type of communication equipment at that time, and switching the network type of communication equipment to another network type if the connected network type of communication equipment at that time is inconsistent with the determined network type corresponding to the use position. According to the method, the network type can be automatically switched to access a network according to different use positions without manual switching, convenience is brought to the life of a consumer, the network access rate is raised, and the customer use experience is good.
