3 is a flowchart illustrating a log data storage method of a mobile terminal according to an embodiment of the present invention.

The method for storing log data of a mobile terminal according to an embodiment of the present invention may be embodied as an application executed in the mobile terminal (hereinafter, referred to as a 'mobile logging tool (MLT) application'). When the mobile terminal is booted and the MLT application is executed, it is monitored whether a predetermined error occurs (S31). The predetermined error may indicate various errors that may occur during use of the mobile terminal. For example, a reset, lock-up, application not responding, call drop, and the like may be described. This may correspond to a predetermined error. Here, the lock-up represents a phenomenon in which the screen (or operation) of the mobile terminal is stopped, and the ANR represents a case in which an application or an application executed in the mobile terminal cannot respond to user input.

If at least one of the above-described predetermined errors occurs (S33), the mobile terminal determines the log data storage condition (S35). Here, the log data storage condition is to determine whether to store the log data according to the usage state of the CPU, memory, and the like of the mobile terminal. Determine when to save data. That is, the storage condition of the log data is, when the available capacity of the CPU of the mobile terminal is greater than or equal to a predetermined reference value, the log data is immediately stored when the error occurs, and if the available capacity of the CPU is less than the predetermined reference value, an error occurs. A condition of storing the log data after a predetermined delay time has elapsed from a time point. Alternatively, the storage condition of the log data may include storing the log data immediately when the error occurs when the available capacity of the memory of the mobile terminal is greater than or equal to a preset reference value, and an error occurs when the available capacity of the memory is less than the preset reference value. A condition of storing the log data after a predetermined delay time has elapsed from a time point.

The log data is stored in a preset memory area at a storage time determined according to the determination result of step S35 (S37).

The log data includes error log information and state information of the mobile terminal when an error occurs. Here, the error log information includes at least one of an error type occurred, an error occurrence time, and call stack information when an error occurs. The error type may be any one of error types monitored in step S31. The call stack information is information on a call stack, which is a stack data structure that dynamically stores information about subroutines of a program to be executed, that is, information about a call relation between functions. Since it is possible to grasp the overall flow performed by a given program up to now and determine what functions have been performed, call stack information is stored in the preset memory area for error debugging of the mobile terminal. On the other hand, the state information of the mobile terminal is information that can be used to determine the overall usage state of the mobile terminal when the error occurs, the mobile terminal usage pattern of the user, the power on / off information of the mobile terminal, call connection information The connection information may include connection information with a peripheral device, battery state information, memory state information, or execution application information. With reference to FIG. 4 where various information items included in the log data are shown, the log data stored in the mobile terminal will be described in more detail.

4 is an exemplary view for explaining log data stored in a mobile terminal. Detailed information of the log data shown in FIG. 4 is merely exemplary, and various information may be stored in addition to the present invention. It will be apparent to those skilled in the art to which the present invention pertains.

Referring to FIG. 4, error log information included in the log data and state information of a mobile terminal are shown.

5 is an exemplary view for explaining a method for providing an interface for displaying log data according to an embodiment of the present invention.

5 is a diagram illustrating an example of an interface for displaying log data according to an embodiment of the present invention. The interface screen for displaying log data may include a first area 510 in which indicators selectable by a user are arranged over time, and a second area 520 in which detailed information of log data is displayed. .

As described above, the log data received from the mobile terminal includes error log information and state information of the mobile terminal when an error occurs, and the error log information includes an error occurrence time. The interface for displaying the log data arranges the log data over time based on the error occurrence time, and removes bar-shaped indicators 511 and 513 corresponding to the respective log data. In one area 510, each indicator is displayed according to an error occurrence time of the corresponding log data. Although the indicator is shown in bar shape in FIG. 5, it will be apparent to those skilled in the art that the shape of the indicator may be variously modified.

In the second area 520, detailed information of the log data is displayed. The second area 520 may include an area 521, 523, 525, and 527 that are classified and displayed by error type, and an area 529 where detailed information corresponding to an indicator selected by a user input is displayed. .

For example, the indicator 511 in the first region indicates the case where a lockup error has occurred, and is displayed as the lockup error 525 in the second region, and the error occurrence time is represented by the horizontal axis or the second region of the first region. Can be identified in the lockup error area of the area. When an indicator 511 is selected by the user input, detailed information such as corresponding error log information and status information of the mobile terminal is displayed in an area 529. As another example, the indicator 513 in the first region indicates a case where an ANR error occurs, and is displayed in the second line of the application error 527 in the second region, and the error occurrence time is displayed in the first region. It can be checked in the application axis of the horizontal axis or the second area. When the indicator 513 is selected by the user input, the corresponding detailed information is displayed in the region 529.

As can be seen from FIG. 5 and the above description, in the interface providing method for displaying log data according to an embodiment of the present invention, log data corresponding to an error occurring in a mobile terminal is arranged on a time axis, and each log data is provided. By displaying the indicator selectable by the user input on the interface screen, the user can easily grasp the error generated in the mobile terminal and the usage pattern of the mobile terminal over time, and increase the efficiency of error debugging. .

Meanwhile, embodiments of the present invention can be implemented by recording a program code that can be read by a computer on a computer-readable recording medium. When embodiments of the present invention are executed using software, the constituent means of the present invention are code segments for performing necessary tasks. The program or code segments may also be stored in a medium readable by a processor of the computer or transmitted in a computer data signal coupled with a carrier wave via a transmission medium or a communication network.

The computer-readable recording medium may include any type of recording device that stores data that can be read by a computer system. For example, the computer-readable recording medium may include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like.
