Disclosed is a resource release and reuse mechanism in a D2D communication system when switching between a mode 1 (Mode 1) and a mode 2(Mode 2). According to the embodiments of the present invention, the method comprises: in the process of transmission in a D2D mode 1, detecting a network condition, and reporting the detected network condition to a base station so as to assist the base station to release a physical resource scheduled to a terminal in time when the transmission is interrupted; and if the detected network condition satisfies a trigger condition of interrupting data receiving, reserving incompletely transmitted data to be sent during the interrupted transmission or all data to be transmitted during this scheduling, and executing switching from a mode 1 to a mode 2, so as to send the reserved data in the mode 2; or waiting to re-access this cell to switch back to the mode 1, so as to send the reserved data in the mode 1. The method of the present invention can increase the utilization rate of resources in a D2D communication system, thereby realizing greater network performance gain. |
