Terminal and application synchronization method therefor

A terminal supporting application synchronization, the terminal comprising:

• a controller configured to receive a first alarm registration request, to determine whether a data transmission and reception action of an application corresponding to the first alarm registration request is detected within a preset time after a trigger time of the first alarm registration request, to perform, when a data transmission and reception action of the application corresponding to the first alarm registration request is detected within the preset time after the trigger time of the first alarm registration request, adjustment by estimating the period of a repetitive synchronization activity associated with the first alarm registration request, and to adjust the execution time of the repetitive synchronization activity according to the period estimation result;
• and
• a communication unit configured to send and receive data under control of the controller.

A terminal comprising:

• a storage unit configured to store an ignore list;
• and
• a controller configured to determine whether an alarm trigger signal is generated, to determine, when an alarm trigger signal is generated, whether an alarm triggered by the alarm trigger signal is a target for application synchronization management, to determine, when the alarm is the target for application synchronization management, whether the alarm is a User Interface (UI) alarm or an abnormal action alarm, and to add, when the alarm is the UI alarm or the abnormal action alarm, information on the alarm to the ignore list.
