When a touch signal is inputted, calculating an area of a valid touch region in which a user touches the touchscreen and comparing the calculated area of the valid touch region with the area threshold value. If the area of the valid touch region is greater than or equal to the area threshold value, controlling the mobile terminal to turn off the alarm. If the area of the valid touch region is smaller than the area threshold value, the alarm of the mobile terminal keeps ringing. Thereby, inconvenient operation associated with turning off a ringing alarm of a mobile terminal according to the prior art is eliminated. ## Claims ### Claim 1 A method for turning off an alarm of a mobile terminal, the method comprising: presetting an area threshold value; automatically turning on a mobile terminal's screen when the alarm of the mobile terminal sets off; detecting a touch signal, when a touch signal is detected, calculating an area of a valid touch region in which a user touches the touchscreen; comparing the calculated area of the valid touch region with the area threshold value, if the area of the valid touch region is greater than or equal to the area threshold value, controlling the mobile terminal to turn off the alarm; and if the area of the valid touch region is smaller than the area threshold value, the alarm of the mobile terminal keeps ringing. ### Claim 2 (depends on 1) The method as set forth in claim 1, wherein, when the screen of the mobile terminal is turned on, detecting a touch signal for a preset time interval. ### Claim 3 (depends on 1) The method as set forth in claim 1, further comprising: pre-storing a plurality of graphics. ### Claim 4 (depends on 3) The method as set forth in claim 3, further comprising: dividing the valid touch region into a plurality of graphics according to the pre-stored graphics, calculating an area of each graphic, adding the area of each graphic together to produce an area sum, and calculating the area of the valid touch region based on the area sum. ### Claim 5 (depends on 3) The method as set forth in claim 3, wherein the graphics comprise at least one of: a rectangle, a circle or a triangle. ### Claim 6 (depends on 1) The method as set forth in claim 1, further comprising: presetting a threshold time and, when the user touches the touchscreen, detecting if the time the user touches the touchscreen exceeds the threshold time, wherein a user touch longer than the threshold time is determined to be a valid touch and the area of the valid touch region is calculated, and wherein a user touch that is not longer than the threshold time is determined to be an invalid touch signal. ### Claim 7 (depends on 6) The method as set forth in claim 6, further comprising: performing an estimated setting according to a palm size and a touchscreen size, and determining a value for presetting the area threshold value based on the palm size and the touchscreen size. ### Claim 8 (depends on 6) The method as set forth in claim 6, wherein when the touchscreen of the mobile terminal is turned on, detecting if a touch signal is inputted for a preset time interval. ### Claim 9 (depends on 7) The method as set forth in claim 7, further comprising: pre-storing a plurality of graphics. ### Claim 10 (depends on 9) The method as set forth in claim 9, further comprising: dividing the valid touch region into a plurality of graphics according to the pre-stored graphics, calculating an area of each graphic and adding the areas of each graphic to produce an area sum, and calculating the area of the valid touch region based on the area sum. ### Claim 11 (depends on 9) The method as set forth in claim 9, wherein the graphics include at least one of: a rectangle, a circle, or a triangle. ### Claim 12 A method for turning off an alarm of a mobile terminal, the method comprising: performing an estimated setting according to a palm size and a touchscreen size, determining a value for presetting an area threshold value; automatically turning on a mobile terminal touchscreen when the alarm of the mobile terminal sets off; detecting a touch signal, when a touch signal is detected, calculating an area of a valid touch region in which a user touches the touchscreen; dividing the valid touch region into a plurality of graphics according to pre-stored graphics, calculating an area of each graphic and adding the area of each graphic to produce an area sum, and calculating the area of the valid touch region based on the area sum; comparing the calculated area of the valid touch region with the area threshold value, if the area of the valid touch region is greater than or equal to the area threshold value, controlling the mobile terminal to turn off the alarm. ### Claim 13 A system for turning off an alarm of a mobile terminal, the system comprising: a storage module for storing a preset area threshold value; a detection module for detecting a touch signal; a calculation module for calculating an area of a valid touch region; a comparison module for comparing the area of the valid touch region with the area threshold value; an alarm control module for controlling the alarm according to a comparison result of the comparison module, wherein when the area of the valid touch region is greater than or equal to the area threshold value, controlling the mobile terminal to turn off the alarm, and wherein when the area of the valid touch region is smaller than the area threshold value, the alarm of the mobile terminal keeps ringing. ### Claim 14 (depends on 13) The system as set forth in claim 13, further comprising: an interrupt module for sending an interrupt signal to the detection module at a preset time interval, wherein the detection module detects a touch signal for the present time interval. ### Claim 15 (depends on 13) The system as set forth in claim 13, wherein the storage module is further for storing a plurality of graphics. ### Claim 16 (depends on 13) The system as set forth in any one of claim 13, wherein the mobile terminal is a mobile phone, or a tablet computer, having a touchscreen. ### Claim 17 (depends on 15) The system as set forth in claim 15, further comprising: dividing the valid touch region into a plurality of graphics according to the stored graphics, calculating an area of each graphic and adding the areas of each graphic to produce an area sum, and calculating the area of the valid touch region based on the area sum. ### Claim 18 (depends on 15) The system as set forth in claim 15, wherein the graphics include at least one of: a rectangle, a circle, or a triangle. ### Claim 19 (depends on 13) The system as set forth in claim 13, further comprising: performing an estimated setting according to a palm size and a touchscreen size, and determining a value for presetting the area threshold value based on the palm size and the touchscreen size. ### Claim 20 (depends on 13) The system as set forth in claim 13, wherein when the touchscreen of the mobile terminal is turned on, detecting a touch signal for a preset time interval.
