<p>A large data object transmission method, transmission system, transmitting device and receiving device are provided. The method comprises the following: during the device management session process, the transmitting device transmits a large data object by blocking to the receiving device (501); if the transmission process is interrupted, the session process is reinitiated (502), and it is determined whether the large data object has changed since the interruption. If it has not, the transmitting device transmits the remaining data of the large data object to the receiving device according to the length of the received data recorded by the receiving device (503). By applying the embodiments of the invention, transmission of a large data object which has been interrupted can be restored during the data synchronization (DS) session, thus saving wireless resources and reducing traffic.</p> |
