The present disclosure provides a mobile terminal and a transmission processing method thereof. The mobile terminal includes: a casing; a motion sensing unit provided within the casing and configured to gather motion data of the mobile terminal; a judging unit connected to the motion sensing unit and configured to judge whether the mobile terminal is performing a predetermined motion based on the motion data gathered by the motion sensing unit; a generating unit connected to the judging unit and configured to generate an operation instruction when the judging unit judges that the mobile terminal is performing the predetermined motion; and a transmitting unit connected to the generating unit and configured to transmit the operation instruction to another terminal. The another terminal performs a vibration operation in response to the operation instruction. With the embodiments of the present invention, an improved efficiency of user input can be achieved.
