A method for controlling an operation of a mobile terminal, the method comprising: setting an automatic login region or time period within the mobile terminal for automatically logging into a network or Internet site by the mobile terminal; determining (S15, S60) by the mobile terminal whether or not the mobile terminal has entered or exited the automatic login region or time period and generating a corresponding determination result; determining whether or not a priority is set for the automatic login region or time period when the mobile terminal is entered the automatic login region or time period (Yes in S20), checking the priority set for the entered automatic login region or time period when priority is set for the entered automatic login region or time period (Yes in S25), automatically logging into (S30, S35, S70) the network or Internet site by the mobile terminal when higher priority or no priority is set for the entered automatic login region or time period; maintaining an automatic login state corresponding to the existing automatic login information when automatic login information set for the entered region or time period collides with existing automatic login information and priority of the automatic login information set for the entered region or time period is lower than priority of the existing automatic login information, displaying a menu or icon to input a command to the mobile terminal to update user information of the automatically logged-in network or Internet site, and if the menu or icon to update user information is selected, determining that a user information update command has been input (Yes in S80) to the mobile terminal, and updating user information of the automatically logged-in network or Internet site, wherein the user information of the automatically logged-in network or Internet site includes information regarding the position of the user stored in the network or Internet site; displaying a menu or icon to input a command to the mobile terminal to upload content to the automatically logged-in network or Internet site when content including a still or moving image is generated through the camera 121a after the mobile terminal automatically logged in to the network or Internet site, and when the menu or icon to upload the content is selected, uploading the content to the automatically logged-in network or Internet site; and automatically logging out of a logged-in network or Internet site by the mobile terminal if the determination result indicates the mobile terminal has moved a predetermined distance away from the automatic login region or when the automatic login time period has expired. setting an automatic login region or time period within the mobile terminal for automatically logging into a network or Internet site by the mobile terminal;
