Abstract: An offline communication method includes steps of: receiving, by a first TDD (Time Division Duplexing) terminal, an instruction for setting the first TDD terminal as a D2D (Device-to-Device) terminal device; interchanging, by the first TDD terminal, upstream time slots and downstream time slots thereof, and setting the first TDD terminal to be in a mode of conforming a D2D communication environment in response to said instruction; and searching, in a mode that the upstream time slots and the downstream time slots are interchanged, for a second TDD terminal which is adjacent to the first TDD terminal and is not set as a D2D mode, and establishing a connection therebetween after the second TDD terminal is searched out. By this way, communication between those offline intelligent mobile terminals within a short distance can be carried out.
