LTE terminal high-speed direct connection method and terminal

Abstract

The invention provides an LTE terminal high-speed straight-through method and a terminal. The method comprises the following steps that a straight-through terminal achieving time synchronization through the prior art is at a called state by default; the terminal uses the up-down row subframe ratio 1 or the ratio 0 by default, a fixed-period blind solution resource is configured at a received sub frame of the terminal, and blind solution is performed on the resource; when the terminal resolves an own identity, communication is performed immediately according to an own empty time sequence, when the terminal performs calling, the own up-down row subframe ratio is adjusted through a clock which deviates from the terminal, and then the fact that a sending subframe of a calling terminal and a received subsframe of the called terminal completely correspond to each other; and the calling terminal sends a terminal identity to be called on the blind solution resource of the called terminal, and then primary communication between the calling terminal and the call terminal can be established. The terminal subsequently ensures transmitting and receiving to be capable of being completed between the calling terminal and the called terminal according a time sequence characteristic. A system achieves direct communication between the terminals.

Description

technical field [0001] The present invention relates to the communication field, and in particular to an LTE high-speed direct connection method and terminal. Background technique [0002] The technology of direct communication between terminals is still at the 2G level, and what is transmitted between terminals is only voice services, which is far from meeting actual requirements. Terminals are also faced with the need for data service transmission. [0003] At present, the public network has entered the LTE era, and the existing emergency solutions implement emergency communications through temporary construction of emergency access networks. However, the emergency access network activated under special circumstances has the risk of being attacked again. At the same time, it is not possible to successfully build an emergency system in any place at any time, so the demand for direct connection of LTE terminals is particularly obvious. [0004] The current problem is that,...
