The present invention relates to a method of managing a battery level in an idle mode of a wireless communication terminal. More specifically, the conventional wireless communication terminal checks and transmits a battery level by periodically operating a monitoring timer in an idle mode. An additional timer (the monitoring timer) is checked by checking the battery voltage level using an activated RF timer and transmitting it to the foreground as the voltage level is changed in comparison with the previously stored battery voltage level. A battery level management method in an idle mode of a wireless communication terminal for reducing current consumption of a battery for driving and transmitting a periodic battery voltage level.

In the present invention, a wireless communication terminal refers to a wireless communication terminal such as a mobile communication terminal, a personal digital communication terminal (PCS), a personal digital terminal (PDA), a smartphone, a next generation mobile communication terminal (IMT-2000), a wireless LAN terminal, and the like.

First, some terms used in the present invention will be described.

Task is a software division of all the work done inside the terminal. All tasks defined as tasks are configured to work independently, as each program runs independently on the computer. For example, a task includes a UI task, a Diag task, and the like.

The infant task (UI Task) is responsible for the screen configuration, the phone book, SMS, photos, etc. that all users see.

In this case, each task may exchange information with each other. In this case, the defined signals may be exchanged to exchange information necessary for each other.

1 is a diagram illustrating an embodiment of a layer of a general wireless communication terminal.

As shown in FIG. 1, a wireless communication terminal includes an application 11 layer for managing a part of a user watching and listening, a layer 1 12 for providing an interface between the application layer and a device layer, and hardware. It includes a device layer 13 (eg, battery hardware) to handle the part.

On the other hand, the battery charging algorithm of the current wireless communication terminal has the following charging timer.

 (1) BMX_TIMER_CHARGING_SAFETY

 (2) BMX_TIMER_TOTAL_POWER_RAMP

 (3) BMX_TIMER_POWER_RAMP_POLL

 (4) BMX_TIMER_CHARGING_POLL

 (5) BMX_TIMER_SUSPEND_POLL

 (6) BMX_TIMER_MONITORING_POLL

Here, except for "BMX_TIMER_MONITORING_POLL", the remaining timers are timers used for actually charging, and "BMX_TIMER_MONITORING_POLL" is a timer used for not charging.

2 is a diagram illustrating an embodiment of a battery level management method in an idle mode of a conventional wireless communication terminal.

As shown in FIG. 2, in order to manage the battery level in the idle mode of the conventional wireless communication terminal, the BMX_TIMER_MONITORING_POLL (22) timer is operated in a 22 second cycle, and the battery level request function (L1BmxSendBattVoltTempReq ()) is called. The battery level is received from the hardware 23 (checking the battery level), and a method of transmitting to the application 21 without comparing with the previous battery level is used.

Conventionally, the battery level is periodically read every 20 seconds, and the battery level is unconditionally transmitted to the foreground. Accordingly, in the foreground, the battery is represented by a battery indicator so that the user can determine how much the battery level is.

That is, conventionally, the battery level is notified to the foreground by using the BMX_TIMER_MONITORING_POLL 22.

Therefore, even when the battery level is the same as before, if the problem is that the current to the Foreground periodically to cause unnecessary consumption, because only one timer to inform the battery level periodically, It causes current consumption in the idle mode.

The present invention has been proposed to solve the above problems, but the conventional wireless communication terminal periodically checks the battery level by operating a monitoring timer in the idle mode and transmits it, but uses an RF timer activated in the idle mode. After checking the battery voltage level and transmitting it to the foreground as the voltage level is changed compared with the previously stored battery voltage level, driving an additional timer (the monitoring timer) and transmitting the periodic battery voltage level It is an object of the present invention to provide a battery level management method in an idle mode of a wireless communication terminal to reduce the current consumption of the battery.

Other objects and advantages of the present invention can be understood by the following description, and will be more clearly understood by the embodiments of the present invention. Also, it will be readily appreciated that the objects and advantages of the present invention may be realized by the means and combinations thereof indicated in the claims.

In accordance with an aspect of the present invention, a method for managing a battery level in an idle mode of a wireless communication terminal includes: a task state run handler (RF) in a predetermined cycle in an idle mode; Transmitting a signal to the device; Requesting, by the task state run handler, a battery voltage level from battery hardware according to the received signal; Comparing the battery voltage level received according to the request with a previously stored battery voltage level; Delivering a battery voltage level to an application and storing a changed battery voltage level as the two voltage levels are different; And displaying the battery voltage level received by the application.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, whereby those skilled in the art may easily implement the technical idea of the present invention. There will be. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention has been studied for the purpose of improving the battery consumption by reducing the current consumption of the wireless communication terminal, by operating a timer task periodically in the existing idle (IDLE) mode to minimize the problem that the current consumption is continuously generated, The algorithm is designed to use RF timer instead of battery idle timer.

3 is a flowchart illustrating a battery level management method in an idle mode of a wireless communication terminal according to the present invention.

First, an RF IDLE Task Timer, which has been previously used, sends a signal to a task state run handler at a predetermined cycle (301).

Then, the task state run handler requests the battery voltage level from the battery hardware using the battery level request signal (302).

Thereafter, it is determined whether the battery voltage level received in response to the request and the previous battery voltage level previously stored are the same level (303).

As a result of the determination 303, the battery voltage level received in response to the request and the previously stored battery voltage level are the same level, and thus the process proceeds to step 307 without transmitting the battery voltage level to the application (304).

Meanwhile, as a result of the determination 303, the battery voltage level received in response to the request and the previously stored battery voltage level are not the same level, and thus the battery voltage level is transmitted to the application, and the changed battery voltage level is stored (305). ).

The application then displays the received battery voltage level (306).

Then, it is determined whether the idle mode ends (307).

As a result of the determination, the idle mode is not terminated.

On the other hand, as a result of the determination 307, the idle mode ends, it ends.

Basically, when using the timer task used in RF (RF) to check if the RF timer is connected to the network periodically in the idle mode, it is signaled by the battery task state run handler. Will be delivered. When this signal is received, the task state run handler requests the battery level from the battery hardware. If the current battery level is the same as the previous battery level, the task state run handler does not deliver the battery level to the application foreground, and differs from the previous battery level. It only passes the battery level to the application foreground.

The present invention is designed based on a signal using an RF timer without using a battery idle timer, and stores the previous battery level and compares the current battery level with the battery in the foreground. By disabling the level, current consumption can be minimized. That is, comparing the previous battery level with the current battery level, if the level is the same, the application is not informed only when it is wrong.

In addition, the present invention can replace the idle timer task (IDLE) that consumes a conventional amount of battery current can reduce the battery consumption. Therefore, there is an advantage that can use a limited amount of battery for a long time.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

In the present invention as described above, the conventional wireless communication terminal periodically checks the battery level by operating the monitoring timer in the idle mode and transmits, but after checking the battery voltage level using the RF (RF) timer is activated in the idle mode Battery current consumption to drive additional timers (the monitoring timer) and transmit periodic battery voltage levels by transmitting to the foreground as the voltage level changes compared to previously stored battery voltage levels. There is an effect to reduce.
