Abstract

A mobile terminal and a control method therefor are disclosed. According to at least one embodiment of the present invention, it is able to provide a mobile terminal capable of reducing consumed power by controlling an alarm period for waking up an application performing synchronization with a server and a method of controlling therefor. Moreover, according to at least one embodiment of the present invention, it is able to provide a solution for controlling an alarm period of an application.

First claim

What is claimed is:

1. A mobile terminal, comprising:
a memory configured to store a plurality of applications performing synchronization by waking up in a predetermined alarm period; and
a controller operably coupled to the memory and comprising:
a data scheduler configured to control the predetermined alarm period by determining an alarm time for waking each application up according to a predetermined condition; and
an alarm service module configured to:
wake each application up at the alarm time determined by the data scheduler;
receive a first signal for requesting a specific alarm for wakeup from a first application among the plurality of the applications; and
transmit a second signal including information on the specific alarm to the data scheduler in response to the received first signal,

wherein the data scheduler is further configured to:
determine an alarm time for waking the first application up based on the information on the specific alarm when the specific alarm relates to data communication for transceiving a packet with a server; and
transmit the determined alarm time for waking the first application up to the alarm service module,

wherein:
the alarm service module is further configured to wake each of the plurality of the applications up at a period of an integer multiple of a predetermined base period (BP);
the data scheduler is further configured to classify each of the plurality of applications into an application belonging to a class among class N (N=0, 1, 2, . . . ) based on the predetermined base period and the predetermined alarm period of a respectively corresponding application; and
class (N) of each application is determined by the following equation 1:
( N− 0.5)*BP<alarm period≤( N+ 0.5)*BP,  Equation 1:

where N is a positive integer, BP is a predetermined base period, and alarm period is an alarm period preset to each application.

2. The mobile terminal of claim 1 , wherein applications belonging to class 0 satisfy the following equation 2:
5 min.<alarm period≤( N+ 0.5)*BP.  Equation 2:

3. The mobile terminal of claim 1 , wherein the information on the specific alarm includes: first information for identifying the specific alarm of the first application; and second information on alarm time at which the first application wakes up according to the predetermined alarm period related to the specific alarm.

4. A method for controlling a mobile terminal comprising an alarm service module and a data scheduler in a controller, the method comprising:
storing, in a memory, a plurality of applications performing synchronization by waking up in a predetermined alarm period;
controlling, by the data scheduler, the predetermined alarm period by determining an alarm time for waking each application up according to a predetermined condition;
waking each application up, by the alarm service module, at the alarm time determined by the data scheduler;
receiving, by the alarm service module, a first signal for requesting a specific alarm for wakeup from a first application among the plurality of the applications;
transmitting, by the alarm service module, a second signal including information on the specific alarm to the data scheduler in response to the received first signal;
determining, by the data scheduler, an alarm time for waking the first application up based on the information on the specific alarm when the specific alarm relates to data communication for transceiving a packet with a server;
transmitting, by the data scheduler, the determined alarm time for waking the first application up to the alarm service module;
waking each of the plurality of the applications up, by the alarm service module, at a period of an integer multiple of a predetermined base period (BP); and
classifying, by the data scheduler, each of the plurality of applications into an application belonging to a class among class N (N=0, 1, 2, . . . ) based on the predetermined base period and the predetermined alarm period of a respectively corresponding application,
wherein class (N) of each application is determined by the following equation 1:
( N− 0.5)*BP<alarm period≤( N+ 0.5)*BP,  Equation 1:

where N is a positive integer, BP is a predetermined base period, and alarm period is an alarm period preset to each application.

5. The method of claim 4 , wherein applications belonging to class 0 satisfy the following equation 2:
5 min.<alarm period≤( N+ 0.5)*BP.  Equation 2:

6. The method of claim 4 , wherein the information on the specific alarm comprises:
first information for identifying the specific alarm of the first application: and
second information on alarm time at which the first application wakes up according to the predetermined alarm period related to the specific alarm.
