Embodiments of the present invention disclose a method, device, and system for realizing device to device communication. The communication method includes: acquiring a wireless network temporary identifier used for device to device communication; receiving transmission grant information scrambled through the wireless network temporary identifier used for the device to device communication; and performing the device to device communication according to descrambled transmission grant information. In the present invention, by sending, to the terminal, the wireless network temporary identifier used for performing the device to device communication and the transmission grant information, the terminal may realize the D2D communication according to the wireless network temporary identifier used for performing the device to device communication and the transmission grant information, thereby satisfying a requirement of D2D data transmission between terminals.
