Description

User terminal and Method for Storing Data Efficiently to increase data storage efficiency

The present invention relates to storing and managing data referenced when a user terminal runs an application. Specifically, it relates to a user terminal and a data storage method of the user terminal that effectively secures a data storage space by storing the data downloaded through the network in a buffer memory and deleting the referenced data when a specific application is terminated. .

With the rapid development of the network infrastructure, various applications and data necessary for driving these applications are being transmitted between numerous terminals, and at the same time, active research is being conducted on a method of managing application data downloaded on the network.

On the other hand, user terminals used by today's consumers are equipped with high-end microprocessors and graphic processing devices that enable consumers to enjoy quality content, and in conjunction with this, they drive applications and applications that can be run on user terminals. The data to be used is also being produced and distributed in large quantities.

As an example, a map application that is currently downloaded by a user terminal such as a smartphone through an app store, etc. is a sum of execution data for actually driving the application and map data for providing location information to the user. It is easy to see that it is composed of a large amount of bytes.

Meanwhile, most smartphones currently store the above map application-related data in a data storage unit provided in the terminal or in the form of a separate memory card, that is, in the main memory, and the user can run the map application. Application-related data is managed by calling the necessary data every time.

However, such a data management method has many problems when considering the recent application market in which data for driving applications is increasing in volume.

Specifically, the user terminal has to allocate a separate storage space for application data that the user does not use frequently, and because it takes up storage space for unnecessary data, the user can download the application data that the user needs. There may be a problem that there is no problem, a problem that data processing is delayed when an application is running due to a large amount of data being stored.

On the other hand, in order to solve the above problems, many user terminal manufacturers are also considering ways to increase the capacity of the internally provided storage space, but this method has a problem that the manufacturing cost of the user terminal can be increased. In light of the current trend in which the types of applications provided to users and data for driving applications are diversified and capacity is increasing, there is no limit to solving the above problems by simply increasing the capacity of storage space. have.

Accordingly, there is a need for a new data management method in which a user terminal can efficiently utilize and delete data without requiring excessive costs.

On the other hand, as a related prior art, there is Korean Patent Registration No. 10-0654462 ("Cache method and cache system for storing file data by dividing a cache memory into memory blocks"). The above prior art is an invention of a cache method and a cache system for storing file data by dividing a cache memory into memory blocks. According to an embodiment of the prior art, a command for requesting first data of a first file is received from an application. The steps of: searching for a memory block in which the requested first data is stored, setting reference information indicating that the memory block in which the first data is stored is referenced by the application, and the first data stored in the memory block And transmitting to an application, and resetting the reference information for a memory block in which the first data is stored.

The above prior art saves a large number of files by dividing them into multiple memory blocks and loading and maintaining the files stored in the memory blocks when streaming data, thereby reducing the time to read the corresponding files from separate storage. In that it is brought, this is partially similar to the purpose of the invention of the application. However, the prior art only describes how to store and access large-capacity, multiple files in divided memory blocks, and the technical composition of the frequency of use of data such as how often the stored data is referenced by the application. It is not suitable for solving the above problems in that it is not disclosed at all, and furthermore, it does not mention the contents of securing storage space by deleting data with low utilization frequency.

Details of the object and the technical configuration of the present invention and the effects of the operation thereof will be more clearly understood by the following detailed description based on the accompanying drawings in the specification of the present invention. An embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, referring to FIG. 1, a method of receiving and managing data for driving an application by the user terminal 10 or data referenced when an application is executed from the content providing server 50 will be described.

Referring to FIG. 1, a conventional user terminal 10 includes an application driving unit 120 for driving an application and a data storage unit 140 for storing data necessary for driving the application.

Meanwhile, the data received from the conventional content providing server 50 is referred to in two ways as follows when an application is executed in the user terminal 10.

The first method is a method in which the user terminal 10 directly refers to the data received from the content providing server 50 in the application without storing it in a separate storage space. This method has an advantage in that it is not necessary to store data in the user terminal 10 and thus a storage space can be secured. However, there is a problem that data must be downloaded every time the application is executed. In the case of large capacity, it takes a lot of time to download and there is a problem that a lot of network bandwidth must be secured.

In the second method, data received from the content providing server 50 is stored in the data storage unit 140 provided in the user terminal 10 and the data is called and referred to when the application is executed. This method is advantageous in that the data stored internally can be easily accessed and referenced each time the application is executed, but the necessary data must be saved every time the application is executed, and furthermore, it is necessary to store the data stored in the application. There is a problem in that you have to allocate a large amount of storage space.

Hereinafter, referring to FIG. 2, a method of calling and referencing downloaded data when the user terminal 100 executes an application according to an embodiment of the present invention will be described.

Referring to FIG. 2, the user terminal 100 according to an embodiment of the present invention preferentially includes an application driver 120 and further includes a data storage unit 140 composed of a buffer memory 142 and a main memory 144. Can include.

In this case, the buffer memory 142 refers to a storage space in which data that can be referenced by the application driver 120 is temporarily stored, and the main memory 144 is, unlike the buffer memory 142, where data is permanently stored. Means storage space that can be used. Further, preferably, the buffer memory 142 may be able to access data faster by using a higher speed memory element than the main memory 144.

Meanwhile, the user terminal 100 may divide and store data received from the content providing server 50 into a buffer memory 142 or a main memory 144 according to a standard set by a user. In this case, the criterion may be a capacity of received data or a frequency of use of an application referencing the data.

That is, the user terminal 100 according to the present invention distinguishes and stores data referenced when running an application according to a specific criterion in the buffer memory 142 or main memory 144 having different properties, Data can be classified and managed according to the frequency of use of the application. In particular, the buffer memory 142 is a configuration that does not exist in the conventional user terminal 100, temporarily stores data received from the content providing server 50, and immediately deletes the data when the application ends, or It can be said to have an important technical significance in that it is possible to reduce the wastage of unnecessary storage space by setting the deletion time limit and automatically deleting it when the corresponding time limit has elapsed. Hereinafter, a more specific configuration of the user terminal 100 and a data management method of the user terminal 100 will be described.

3 is a block diagram showing a detailed configuration of a user terminal 100 according to an embodiment of the present invention. Referring to FIG. 3, a user terminal 100 according to the present invention includes a data receiving unit 110, a data storage unit 140, an application driving unit 120, a data management unit 130, and a control unit.

First, the data receiving unit 110 receives data referenced when the application is driven from the content providing server 50 outside the user terminal 100.

In this case, the data receiving unit 110 may transmit and receive data through various networks including a local area network, a wired communication network, a wireless communication network, and a mobile communication network. For example, RF (Radio Frequency), Bluetooth (Blue Tooth), Zigbee, WLAN (Wireless LAN), WiFi, Wibro, Wimax, HSPDA (High Speed Downlink Packet Access), Ethernet Various communication methods such as (Ethernet), xDSL (ADSL, VDSL), HFC (Hybrid Fiber Coaxial Cable), FTTC (Fiber to The Curb), FTTH (Fiber To The Home) can be used.

In addition, the content providing server 50 refers to a server of a company that provides various types of content such as applications and media, and the server can transmit data to the user terminal 100 through a wired or wireless network communication network. .

In addition, data referenced when running an application means all types of data necessary to actually run the application, and the type may be execution data or data in a DB format that can be referenced when running the application. For example, assuming that the application running in the user terminal 100 is a map application, the data referenced when driving the application is an executable file required to run the map application, that is, the user interface of the map application. ) It may be an executable file consisting of a command to display on the screen, a command to configure an interface to receive input from a user, etc., and also DB format data that can be referenced when executing the map application, that is, a two-dimensional map of multiple regions It may be data in a DB format consisting of information in which images are stored or information on restaurants in the area listed.

Meanwhile, the data storage unit 140 stores data received through the data receiving unit 110. In this case, the data storage unit 140 may include memories having different properties, and particularly preferably, may include a buffer memory 142 and a main memory 144.

As described above in FIG. 2, the buffer memory 142 is a storage space for temporarily storing referenced data when the application is driven, and can be implemented as a high-speed memory device. Accordingly, the storage capacity is generally smaller than that of the main memory 144. However, it can show better performance in terms of data processing speed. Therefore, when executing an application that needs to refer to a large amount of data, it may be more advantageous in terms of application driving speed to refer to the data stored in the buffer memory 142 rather than the data stored in the main memory 144.

Meanwhile, the application driver 120 refers to data stored in the data storage unit 140 and executes a corresponding application according to a user's application execution command. That is, when a specific application execution command is received from a user, the application driving unit 120 calls data necessary for executing the application from the data storage unit 140 to execute the application.

On the other hand, the data management unit 130 is the most essential configuration of the detailed configuration of the user terminal 100 according to the present invention, the step of storing the data received through the data receiving unit 110 in the data storage unit 140, or It is involved in all steps of managing data in the user terminal 100, such as deleting or maintaining data when the application is terminated.

According to a preferred embodiment, the data management unit 130 measures the capacity of the data received through the data receiving unit 110, so that data above a reference value is stored in the buffer memory 142, and data below the reference value is stored in the main memory memory 144. Can be divided and stored. For example, assuming that the reference value is 1 GB, the data management unit 130 temporarily stores 1 GB or more of large-capacity data in the buffer memory 142 to secure a storage space in the user terminal 100 and at the same time, the application driver 120 ) To access the data stored in the buffer memory 142 by calling, it is also possible to obtain an effect of faster processing of large-capacity data. Meanwhile, the data management unit 130 efficiently manages the storage space in the user terminal 100 by storing data less than 1 GB, that is, data that does not take up much storage space in the main memory 144.

Meanwhile, in the above example, the reference value was described assuming 1 GB, but the scope of the present invention should be viewed as not limited to the case where the reference value is 1 GB, and it is understood that the above reference value can be logically set to various values other than 1 GB. Should be.

On the other hand, when the application running on the user terminal 100 is terminated, the data management unit 130 performs a function of deleting data referenced for driving the application. For example, when the use of the map application is finished and the application is terminated, the data management unit 130 recognizes the end of the application and data referenced when the map application is driven, that is, map information data including a map image. By deleting the data, the allocated storage space for data that has been used can be secured. In this case, preferably, the data may be stored in the buffer memory 142.

On the other hand, when the application running on the user terminal 100 is terminated, the data management unit 130 sets a certain time limit for the data referenced for driving the application, and when the time limit elapses, the data management unit 130 performs a function of deleting the data. May be. Taking the above map application as an example, the data management unit 130 may recognize the termination of the application and set a time limit of 600 minutes for data referenced when the map application is driven, that is, map information data. The reason for setting a separate time limit without deleting data at the same time as the application is terminated is to allow the data to be recalled and referenced when the same application is executed again as described below, and the time limit of 600 minutes has elapsed. After that, the data management unit 130 secures a storage space by deleting the map information data.

Meanwhile, as mentioned above, when the same application is re-executed before the time limit has elapsed, the data management unit 130 initializes the setting time limit for the data, and when the re-executed application is terminated, the time limit is set again.

Meanwhile, when the application is terminated, the data management unit 130 may calculate the execution frequency of the application through a separate calculation process, and may determine whether to delete data according to the execution frequency. In this case, the execution frequency of the application is a specific value calculated based on how many times the application has been executed during a predetermined period, and a method of obtaining the execution frequency may be variously implemented according to the intention of the user.

On the other hand, when the application is terminated, the data management unit 130 may measure a capacity of data referenced for driving the application, and may determine whether to delete data according to the measured capacity.

As described above, the present invention basically separates and stores the referenced data in the buffer memory 142 according to the data capacity when the application is running, the technology to delete the referenced data when the application is terminated, and the application is executed for a set time by setting a certain time limit upon termination. Data storage space that is unnecessarily allocated to the user terminal 100 by implementing a technology for deleting data of an application that does not exist, a technology for deleting data according to the execution frequency of the application when the application is terminated or the amount of data referenced when the application is running. The main challenge is to minimize the problem.

Meanwhile, the user terminal 100 according to the present invention also includes a control unit that controls the data receiving unit 110, the data storage unit 140, the application driving unit 120, and the data management unit 130 as a whole.

Hereinafter, a data management method of the user terminal 100 according to an embodiment of the present invention will be described in detail with reference to FIG. 4.

Referring to FIG. 4, in the data management method of the user terminal 100 according to an embodiment of the present invention, first, the user terminal 100 receives data referenced when running an application from an external content providing server 50 (S10) In this case, the referenced data when running the application includes all types of data necessary to actually run the application, that is, execution data or data in DB format, as described above.

Meanwhile, after step S10, the user terminal 100 measures the capacity of the received data and compares it with a reference value preset by the user (S12). If the size of the measurement result data is greater than or equal to the reference value, the corresponding data is stored in the buffer memory 142 among the data storage unit 140 (S14), and if it is less than the reference value, the data is stored in the main memory 144 (S15). The reason for storing the data in the buffer memory 142, which is a temporary storage means, is to secure a storage space in the user terminal 100 as described above and at the same time utilize the buffer memory 142 capable of faster data processing. This is to enable quick access to the network.

After the data whose storage location is determined according to the reference value is stored in the buffer memory 142 or the main memory 144, respectively, the user terminal 100 calls the data stored in the data storage unit 140 and drives the application (S16, S17).

On the other hand, when an application termination command is input by the user, the user terminal 100 recognizes the application termination (S18) and deletes the data stored in the buffer memory 142 (S20). At this time, the deletion is limited to the large-capacity data stored in the buffer memory 142, and it is preferable that the data stored in the main memory 144 are not deleted.

Hereinafter, a data management method of the user terminal 100 according to another embodiment of the present invention will be described with reference to FIG. 5.

First, the main technical configuration of the present invention is a method of managing data stored in the buffer memory 142. In the description of FIG. 5, it is assumed that large-capacity data above the reference value is already stored in the buffer memory 142. do.

First, the user terminal 100 calls the data stored in the buffer memory 142 and refers to the data to drive the application (S30).

On the other hand, when it is recognized that the application is terminated (S32), the user terminal 100 sets a predetermined time limit for the data referenced when the application is driven (S34).

When the time limit set for the specific data has elapsed, the user terminal 100 deletes the data from the buffer memory 142 (S38). However, if the application is re-executed before the set time limit elapses, the user terminal 100 initializes the previously set time limit so that data is not deleted. Further, the user terminal 100 returns to the application driving step (S30) and sets the data time limit (S34) again when the application is terminated (S32).

According to the embodiment of FIG. 5, repeated data download can be prevented by continuously storing the data on the buffer memory 142 without deleting the data referenced by the application that is repeatedly re-executed within a certain time period. It can reduce the burden of downloading large amounts of data every time an application is executed, such as data usage fees and network usage fees.

Hereinafter, a data management method of the user terminal 100 according to another embodiment of the present invention will be described with reference to FIG. 6.

First, the user terminal 100 calls the data stored in the buffer memory 142 and drives the application based on this (S50).

Meanwhile, when the application is terminated (S52), the user terminal 100 may calculate an execution frequency of the application, and determine whether the calculated execution frequency is equal to or greater than a reference value preset by the user (S54).

As a result of the determination, when the application execution frequency is less than the reference value, that is, when it is determined that the application is not frequently used, the data referenced by the application is considered to be relatively low in necessity and thus is deleted (S56). On the other hand, when the application execution frequency is greater than or equal to the reference value, data is held in the buffer memory 142 (S55) so that the application can be easily referred to when the application is executed later.

According to the embodiment of FIG. 6, the user terminal 100 can calculate the execution frequency of a specific application, and can distinguish frequently referenced data from other data based on the calculated execution frequency. There is an advantage that a storage space in the user terminal 100 can be secured by deleting low data.

Although the preferred embodiments and application examples of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments and application examples described above, and the present invention is not departing from the gist of the present invention claimed in the claims. Various modifications may be possible by those of ordinary skill in the art to which they belong, and these modifications should not be understood as being distinguished from the technical spirit or prospect of the present invention.

The present invention can be applied to the field of data storage, and in particular, a method for efficiently managing data in order to secure storage space in terminals with insufficient data storage space, and a new technical configuration for a user terminal performing such data management Provides. According to the present invention, it is possible to collectively determine whether to manage data, that is, whether to delete or maintain, according to the capacity of downloaded data and the frequency of use of an application, and thus there is an advantage in that efficient data management in the user terminal is possible. In view of these points, the present invention can be said to be a useful invention with industrial applicability.
