Unified management method of various types of messages of a personal information terminal

A mobile terminal, comprising:

• a display to display a first input window configured to receive a first message, wherein the first input window comprises a plurality of first message fields;
• and
• a controller configured to determine, when input data is received into at least one of the first message fields of the first input window, whether the input data does not conform to a format corresponding the first input window corresponding to the first message, and output a notification after the input is determined not to conform to the format corresponding to the first input window corresponding to the first message,
• wherein the display is to display a second input window configured to receive a second message, wherein the second input window comprises at least one second message field different from the at least one first message field.

A method for controlling a mobile terminal, comprising:

• displaying a first input window configured to receive a first type message, wherein the first input window comprises a first window identifier and at least one first message field, the first window identifier indicative of a type of the first input window;
• receiving input data into at least one first message field of the first input window;
• determining whether the input data conforms to a format of a second input window corresponding to a second type message;
• outputting a notification after the input data is determined to conform to the format of the second input window corresponding to the second type message, wherein second input window comprises a second window identifier and at least one second message field;
• and
• converting information of the first input window into the format of the second input window corresponding to the second type message, wherein the first and second input windows are displayed on the display at different times.
