How to provide a smart calendar {METHOD OF PROVIDING SMART CALENDER AND SERVER PERFORMING THE SAME}

The present invention relates to a smart calendar providing technology, and more particularly, to a calendar server for executing the smart calendar providing method that can share the schedule between at least one user terminal included in the user group.

Today, with the development of the information and communication field, the use of mobile communication terminals has become popular. With the widespread use of such mobile communication terminals, various technologies using mobile communication terminals have been developed and applied. An additional service associated with a mobile terminal includes a schedule management function for inputting a scheduled schedule such as a meeting, an appointment, a reservation, and the like. Such a schedule management function corresponds to a function of letting the user recognize a schedule through an alarm at a corresponding date and time when the terminal user inputs only his or her schedule.

Korean Patent Publication No. 10-2006-0075986 relates to a device and a method for automatic schedule management and execution. The smart scheduler can input various types of data and process the data by automatic analysis. In addition to the schedules that follow, you can handle event elements such as places or the specific state of the user.

Korean Patent Laid-Open Publication No. 10-2003-0052030 relates to a schedule sharing method and a mobile communication terminal between mobile communication terminals. The schedule management content is shared by setting a sharing function for the schedule content entered in the schedule management mode of the mobile communication terminal. Cross-certification is performed between the mobile communication terminals to be transmitted, and a short message composed of the schedule contents input when the user selects the sharing button for the new schedule contents by the user is transmitted to the counterpart terminal to which the schedule contents are shared. You can automatically enter the calendar mode.
