A dynamic tracking area setting method based on terminal mobile characteristics relates to the mobile communication technical field, and especially relates to a dynamic area setting method based on a mobile terminal; the method mainly comprises the following steps: 1, creating a dynamic tracking area DTA matched with the terminal; 2, building a community adjacent relation location drawing; 3, updating the DTA, and updating positions when the terminal crosses the DTA. Whether the DTA has changed or not can be determined according to a terminal mobility grade parameter, and community indication and adjacent community broadcast obtained in downlink broadcast of the community to which the terminal is located; correspondingly, paging is only broadcasted on all base stations contained by the DTA. The method can customize single DTA management according to terminal self internet of things application mobile characteristics one by one, thus minimizing total signaling cost, and improving data transmission efficiency.
