A mobile terminal comprising: a placement attitude detector; and a controller configured to: detect an incoming call event and, if the mobile terminal is set in a ring mode, output an audio ringing signal corresponding to the incoming call event; the placement attitude detector arranged to detect a placement attitude of the mobile terminal; wherein the controller is configured to: control, in response to detection of said incoming call event, the placement attitude detector to determine whether the placement attitude is changed to a first placement attitude while the audio ringing signal is outputted; and in response to the placement attitude being changed to said first placement attitude and maintained for a preset time duration while the audio ringing signal is outputted, switch from the ring mode to process the incoming call event in a mode without ringing, wherein, in the first placement attitude, a front surface of the mobile terminal faces downward. a placement attitude detector; and a controller configured to: detect an incoming call event and, if the mobile terminal is set in a ring mode, output an audio ringing signal corresponding to the incoming call event; the placement attitude detector arranged to detect a placement attitude of the mobile terminal; wherein the controller is configured to: control, in response to detection of said incoming call event, the placement attitude detector to determine whether the placement attitude is changed to a first placement attitude while the audio ringing signal is outputted; and in response to the placement attitude being changed to said first placement attitude and maintained for a preset time duration while the audio ringing signal is outputted, switch from the ring mode to process the incoming call event in a mode without ringing, wherein, in the first placement attitude, a front surface of the mobile terminal faces downward. detect an incoming call event and, if the mobile terminal is set in a ring mode, output an audio ringing signal corresponding to the incoming call event; the placement attitude detector arranged to detect a placement attitude of the mobile terminal; wherein the controller is configured to: control, in response to detection of said incoming call event, the placement attitude detector to determine whether the placement attitude is changed to a first placement attitude while the audio ringing signal is outputted; and in response to the placement attitude being changed to said first placement attitude and maintained for a preset time duration while the audio ringing signal is outputted, switch from the ring mode to process the incoming call event in a mode without ringing, wherein, in the first placement attitude, a front surface of the mobile terminal faces downward. control, in response to detection of said incoming call event, the placement attitude detector to determine whether the placement attitude is changed to a first placement attitude while the audio ringing signal is outputted; and in response to the placement attitude being changed to said first placement attitude and maintained for a preset time duration while the audio ringing signal is outputted, switch from the ring mode to process the incoming call event in a mode without ringing, wherein, in the first placement attitude, a front surface of the mobile terminal faces downward.
