Offline communication method and intelligent mobile terminal

An offline communication method, comprising 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 communicating with another terminal device:
• interchanging, by the first TDD terminal, upstream time slots and downstream time slots of the first TDD terminal, and setting the first TDD terminal to be in a mode of conforming to a D2D communication environment in response to said instruction;
• and
• searching, by the first TDD terminal 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 the D2D mode, and establishing a connection between the first TDD terminal and the second TDD terminal after the second TDD terminal is searched out.

An intelligent mobile terminal, which is a first TDD terminal (Time Division Duplexing), said intelligent mobile terminal comprising:

• a processor;
• and
• a memory connected with the processor, the memory comprising a plurality of program instructions executable by the processor configured to execute a method, the method comprising:
• receiving an instruction for setting the first TDD terminal as a D2D (Device-to-Device) terminal device communicating with another terminal device;
• interchanging upstream time slots and downstream time slots of the first TDD terminal, and setting the first TDD terminal to be in a mode of conforming to a D2D communication environment in response to said instruction;
• 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 the D2D mode;
• and
• establishing a connection to the second TDD terminal which is adjacent to the first TDD terminal and is not set as the D2D mode after the second TDD terminal is searched out.
