Abstract

An embodiment of the invention discloses a method, terminal and system for achieving device-to-device communication. The communication method includes: acquiring a radio network temporary identity for the device-to-device communication; receiving transmission authorization information scrambled by the radio network temporary identity for the device-to-device communication; and performing the device-to-device communication according to the descrambled transmission authorization information. The radio network temporary identity for the device-to-device communication and the transmission authorization information are sent to a terminal, the terminal can achieve device-to-device (D2D) communication according to the radio network temporary identity for the device-to-device communication and the transmission authorization information, and D2D data transmission requirements between terminals are met.

Description

technical field [0001] The present invention relates to the communication field, in particular to a device-to-device communication method, terminal and system. Background technique [0002] Device-to-device (English full name: device to device, hereinafter referred to as: D2D) technology is a communication technology that directly exchanges data between devices under the control of a mobile network. At present, the D2D technology under systems such as long-term evolution (English full name: long term evolution, hereinafter referred to as: LTE) is still in a conceptual stage, and no standardization work has been started. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is how to realize device-to-device communication. [0004] In order to solve the above technical problems, an embodiment of the present invention provides a device-to-device communication method, including: [0005] Obtain a temporary wireless...
