OFFLINE COMMUNICATION METHOD AND INTELLIGENT MOBILE TERMINAL

摘要

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.

1. 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; wherein the first TDD terminal and the second TDD terminal use an identical channel, and operation time slots of the first TDD terminal are synchronous with that of the second TDD terminal after the connection between the first TDD terminal and the second TDD terminal, which is not set as the D2D mode, is established.
