The following detailed description of the invention refers to the accompanying drawings, which illustrate, by way of illustration, specific embodiments in which the disclosure may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the specification. It should be understood that the various embodiments herein are different, but need not be mutually exclusive. For example, certain features, structures, and characteristics described herein may be implemented in other embodiments without departing from the spirit and scope of the disclosure in relation to one embodiment.

It is also to be understood that the location or arrangement of the individual components within each disclosed embodiment may be variously modified without departing from the spirit and scope of the disclosure. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of this specification is defined in principle in the appended claims, encompassing the appended claims and their equivalents. Where similar reference numerals are used in the figures, like reference numerals refer to the same or similar functions for various embodiments.

As the amount of mobile data traffic increases, the communication cost of the user increases and the traffic of the mobile communication network increases. This is because the user downloads the application or content data to be used at the time of using the mobile communication network, . In other words, conventionally, when downloading is requested, data is immediately downloaded from a usable communication network at that time. Therefore, the communication environment to be downloaded and the point-in-time to download can not be appropriately selected, and accordingly it is judged that the communication cost and traffic have increased.

Meanwhile, in the conventional method, a method of downloading data by connecting a wired host terminal and a mobile terminal instead of a high-cost mobile communication network has been proposed. In this case, however, only a wired terminal that is set to be synchronized with the mobile terminal can download .

On the other hand, in the present invention, data (for example, application or content data) expected to be used by a user or expected to be downloaded is transmitted to a preferred network (for example, WiFi, Bluetooth or the like as a low- The communication cost can be reduced by downloading in advance. Further, the mobile device disclosed in the present invention may provide a means for pre-downloading data in preparation for moving to an area where communication is difficult.

For example, assume that a user is planning to travel to Jeju Island. At this time, it can be expected that the user will need various large-capacity application programs and content data including map of the destination, location-based point of interest (POI) service information including the restaurant information, and augmented reality service data. In this case, if the user preliminarily downloads necessary data through an inexpensive communication environment such as a wired communication network or Wi-Fi, the user can use the desired service on the travel destination without any difficulty.

On the other hand, if not, the user must download the data through a high-cost mobile communication network at a travel destination, and sometimes the necessary data may not be downloaded at a desired location in a mobile communication environment. The present invention provides effective means for solving these problems, and according to the present invention, a user can efficiently receive a low-cost and high-quality data transmission service.

Hereinafter, a specific method for carrying out the present invention will be described as an embodiment related to the drawings.

Mobile terminal 1100 includes CDMA, UMTS (3G) based on LTE, E-UMTS (4G) mobile phone, smart phone, tablet PC or PDA. However, it is to be appreciated that the mobile terminal 1100 may include various mobile electronic devices based on various other communication standards.

The mobile terminal 1100 determines, based on the user's terminal usage information, a dynamic download list that indicates data that the user is expected to use or expect to download. When the mobile terminal 1100 accesses the preferred network of low cost or high quality, it refers to the dynamic download list and downloads necessary data in advance. The terminal usage information of the user further includes user information including the usage pattern of the user, and status information and network status information of the terminal. The data that is dynamically downloaded may include various applications, content, or other data.

More specific configurations and operations of the mobile terminal 1100 will be described in more detail below in FIG. 2 and below.

The network 1200 is connected to the mobile terminal 1100 and relays the data communication of the mobile terminal 1100. The network 1200 may be any type of network, such as a WiBro, a UMTS (3G), a mobile communication network such as an E-UMTS (4G) or Femtocell, a wireless network such as WiFi or Bluetooth, a LAN, Includes a wired network. However, this is exemplary and network 1200 may include any data transmission or data relaying means not described herein.

2 is a block diagram illustrating a specific configuration of a mobile terminal according to an embodiment of the present invention. Referring to FIG. 2, the mobile terminal 100 includes a processor 110, a connection management unit 120, a communication unit 130, a communication interface 140, a download management unit 150, and a storage unit 160. However, it is to be understood that the mobile terminal 100 may further include other components included in a general communication terminal, in addition to those shown here. The mobile terminal 100 of FIG. 2 and the mobile terminal 1100 of FIG. 1 are substantially identical to each other.

The processor 110 controls the overall operation of the mobile terminal 100. The processor 110 may be embedded as part of one processing chip, or may be formed of a single independent chip, or a plurality of processing chips may be combined. The processor 110 is connected to the other hardware modules 120, 130, 140, 150 and 160 of the mobile terminal 100 and is connected to the mobile terminal 100 and the hardware modules 120, 130, 140, And data flows between the hardware modules 120, 130, 140, 150, The processor 110 may perform various operations to drive the hardware modules 120, 130, 140, 150, and 160, and may further provide the computing processing required for the dynamic download of the present invention.

The connection management unit 120 identifies the network environment that can be accessed according to the monitored network environment through the communication interface 140. [ And controls the communication unit 130 to connect to any one of the network environments in which the mobile terminal 100 is connectable according to a predetermined connection setting or a user's request.

The communication unit 130 collects information on the connectable network environment and transmits the collected information to the connection management unit 120. The communication unit 130 activates the communication interface 140 under the control of the connection management unit 120 and connects the mobile terminal 100 with the external network environment. The communication unit 130 includes hardware means and software means for controlling and managing the communication interface 140. [ For example, the communication unit 130 includes a baseband chipset for mobile communication.

The communication interface 140 may include at least one mobile communication interface (e.g., UMTS, E-UMTS, Wibro interface, etc.) with an interface for WiFi or Bluetooth communication. The communication interface 140 forms a communication channel between the mobile terminal 100 and the network 1200 (see FIG. 1) by activating at least one of a plurality of interfaces provided according to a communication environment to which the mobile terminal 100 is connectable do.

The download manager 150 checks whether the application or content data installed in the mobile terminal 100 is updated, whether there is data that has not yet been downloaded, a list of data to be newly downloaded, and the like. Is to be dynamically downloaded. Then, dynamic downloading is performed and managed according to the determined result.

As an example, when the dynamic download is not completed successfully due to a network connection error during dynamic download, the download manager 150 retries the failed download or stores the related download information, and when the network connection is restored, Can be retried.

The download management unit 150 can determine data to be actively downloaded based on user information indicating a terminal usage pattern of a user, terminal information indicating a state of the terminal, or network information indicating a connectable network state, And the point of time can be determined to dynamically download the necessary data.

Specifically, the download management unit 150 comprehensively analyzes an application to be updated, a content to be used in an application, a terminal usage pattern of a user, a content subscription list of a user, or a schedule of a user. Then, according to the analysis result, the download management unit 150 determines a list of data to be subjected to dynamic downloading and a priority among them. At this time, the priority order can be determined based on metadata related to data such as importance of data, expected use date, size, expiration date, and the like.

Then, when the mobile terminal 100 connects to a network environment (e.g., a low-cost or high-quality network environment) satisfying the dynamic download setting condition, the download manager 150 downloads the necessary data based on the determined list and priority And controls the dynamic download operation of the mobile terminal 100 to be downloaded through the connected network environment. At this time, the download management unit 150 can automatically perform the dynamic download according to the predetermined dynamic download setting even if there is no separate user command.

As an embodiment, the download management unit 150 can control the dynamic download operation by referring to the free space of the storage unit 160 or the size of data to be dynamically downloaded. For example, the download management unit 150 may perform a dynamic download after a sufficient free space of the storage unit 160 is secured, or a method of first downloading only a part of necessary data within the free space of the storage unit 160 You can perform dynamic downloads.

The storage unit 160 provides the mobile terminal 100 with data storage means. The storage unit 160 includes at least one volatile storage medium or non-volatile storage medium. The storage unit 160 may include a DRAM, an SRAM, an MRAM, a PRAM, an RRAM, a flash memory, a solid state drive (SSD), an SD card, a Mini-SD card or various other data storage devices.

As an example, the storage unit 160 may include an application storage area 161, a content data storage area 162, or a user information storage area 163 physically or logically divided.

According to the above configuration, the user can dynamically download necessary data based on the terminal usage information through an appropriate network environment. Accordingly, the user can be provided with a better quality data transmission service at a lower cost. Further, the traffic of the mobile communication network can be reduced and the burden of establishing the mobile communication network of the communication carrier can be reduced.

3 is a schematic diagram schematically illustrating a dynamic download method of a mobile terminal according to an embodiment of the present invention. Referring to FIG. 3, the mobile terminal 2100 receives data from the network 2300 with reference to the download information 2200.

In the mobile network system 2000, the mobile terminal 2100 performs dynamic downloading from the external network 2300 with reference to the download information 2200.

The download information 2200 includes user information, terminal information, and network information. Here, the details of the user information, the terminal information, and the network information are the same as those described in FIG. The download information 2200 is typically stored in the mobile terminal 2100, but is not limited thereto. For example, when the mobile terminal 2100 performs dynamic downloading, the mobile terminal 2100 can receive the download information 2200 stored in the external.

The network 2300 is a network capable of providing a data transmission service at a low cost or with a high quality. Network 2300 may be a wireless connection network such as WiFi, Bluetooth, or a wired connection network such as a LAN. The network 2300 is a network that does not use the mobile communication network of the communication company and does not incur the use cost of the mobile communication network without burdening the traffic of the communication company. However, the present invention is not limited thereto. For example, if the mobile communication network can be used at a low cost at a specific time due to a change in the communication environment, the network 2300 may include a mobile communication network used at the relevant time.

The mobile terminal 2100 dynamically downloads data such as applications, contents, etc. from the network 2300 according to the download information 2200. The mobile terminal 2100 determines data that is expected to be used or needs to be downloaded according to the download information 2200 and dynamically pre-downloads the determined data from the network 2300. The mobile terminal 2100 automatically downloads data (or application or content) according to a predetermined dynamic download condition even if the mobile terminal 2100 does not receive a request from the user. The mobile terminal 2100 predicts the use of the user in advance, Therefore, the downloading point of the data can be considerably ahead of the point of use of the data.

The manner in which the mobile terminal 2100 performs dynamic downloading is described in greater detail in FIG.

4 is a block diagram further illustrating a dynamic download method of a mobile terminal according to an embodiment of the present invention. Referring to FIG. 4, the mobile terminal 200 first determines a list to be dynamically downloaded, and performs a dynamic download by referring to a download list determined according to a network environment. Here, the mobile terminal 200 shows substantially the same configuration as the mobile terminal 2100 of FIG.

First, the mobile terminal 200 reads the user information 210 or the terminal information 220. Then, referring to the read information, a list to be subjected to the dynamic download is determined and their download priority is determined (230). The priority may be automatically determined according to a predetermined criterion of the user or the maker of the mobile terminal 200, or may be manually determined by requesting user input for prioritization. For example, the download priority may be determined based on metadata related to data such as importance of data to be subjected to dynamic download, expected use date, size, expiration date, and the like.

Next, the mobile terminal 200 refers to the network information indicating the connectable network environment to determine a network to perform the dynamic download. Specifically, the mobile terminal 200 determines whether there is a network environment that meets the dynamic downloading condition of the connectable network environment. If there is a network environment conforming to the conditions, the mobile terminal 200 accesses any one of them and performs dynamic download according to the determined list and their priorities. At this time, if there are a plurality of network environments meeting the conditions, the mobile terminal 200 may arbitrarily select one of the network environments or perform dynamic downloading by preferentially selecting any one of them according to a predetermined criterion. On the other hand, if there is no network environment meeting the condition, the mobile terminal 200 does not perform dynamic downloading.

According to the above configuration, the user can dynamically download necessary data based on the terminal usage information through an appropriate network environment. Accordingly, the user can be provided with a better quality data transmission service at a lower cost. Further, the traffic of the mobile communication network can be reduced and the burden of establishing the mobile communication network of the communication carrier can be reduced.

5 is a flowchart illustrating a method for determining a dynamic download list, in accordance with an embodiment of the present invention. Referring to FIG. 5, the download list determination method includes steps S110 to S150.

In step S110, the user can select whether to activate the dynamic download function through the user interface. That is, by disabling the dynamic download function, the user is prompted to download the data immediately when the user desires, or the dynamic download function is activated as in the normal download method, and a low-cost high-quality network environment is set according to download information (user information, terminal information or network information) So that data can be downloaded in advance. If the dynamic download is disabled, the dynamic download list determination method ends. On the other hand, if the dynamic download is activated, the method of determining the dynamic download list proceeds to step S120.

In step S120, the mobile terminal 100 (see FIG. 2) confirms current time information, location information of the terminal, and dynamic download information from the terminal information.

Here, the dynamic download information means setting information for dynamic download. The setting information may include various information such as an application to which the dynamic download function is to be applied, a type of content or data, a criterion for determining data to be dynamically downloaded from the user information, and a download policy to be applied at the time of dynamic download. Here, as described above, the user information includes information such as a user's terminal usage pattern, a user's content subscription list, a user's schedule, a user's to-do list, personal information such as a user's address book, Map data, route information, theme information, or POI information.

In step < RTI ID = 0.0 > S130, < / RTI > the mobile terminal 100 determines the data to perform dynamic download according to the identified time information, location information or dynamic download information. At this time, the mobile terminal 100 may refer to the confirmed location and time information, and may exclude data for which the user is no longer expected to use or expired. Step S130 is further specified in Fig.

In step S140, the mobile terminal 100 determines a download list (or download reserve list), data information, and download priority based on the data to be subjected to the dynamic download. At this time, the download priority may be determined based on metadata related to data such as importance of data, expected use date, size, expiration date, and the like. The download list is a list showing all of the data determined to be a target of the dynamic download in step S130. The download list is a list of the download list before the order is rearranged in consideration of the size of the data, the free space of the storage unit, Because it is a list, it can be seen as a sort of preliminary list.

The data information is additional information indicating an attribute of the data to be subjected to the dynamic download, an expiration date, and the like. For example, the data information may be dynamic download expiration information that excludes specific data from dynamic download targets after a certain point in time. Alternatively, the data information may be automatic deletion information that causes the dynamic download to be automatically deleted after a specific point in time. The data information can be used to reserve the storage space of the mobile terminal 100 by anticipating the data usage time of the user and not deleting or downloading the data after an expected period of time.

The download priority means a priority among the data to be subjected to the dynamic download. The priority may be automatically determined according to a predetermined criterion, or manually determined according to user input.

In step S150, the mobile terminal 100 finally determines the data to be dynamically downloaded by referring to the free space of the storage unit. Specifically, the mobile terminal 100 compares the size of the entire data registered in the preliminary list with the free space of the storage unit, and then, when all the data can not be stored, the mobile terminal 100 dynamically downloads the data within an allowable range within the free space of the storage unit And determines the data. The mobile terminal 100 may then update the preliminary list or generate a new download list according to the determined result. On the other hand, if all of the data can be stored in the free space of the storage, the mobile terminal 100 can keep the spare list intact or create a new download list to include all the data of the spare list. Step S150 is further specified in Fig.

According to the above configuration, the user mobile terminal can determine the list of data to be subjected to dynamic download based on the usage information.

6 is a flow chart further illustrating step S130 of FIG. Referring to FIG. 6, step S130 is embodied as steps S131 to S133.

When step S120 is completed in FIG. 5, step S131 of FIG. 6 is performed.

In step S131, the mobile terminal 100 (see FIG. 2) confirms and analyzes the update information of the application to which the dynamic download is applied, and determines application data to be dynamically downloaded accordingly.

In step S132, the mobile terminal 100 confirms and analyzes the update information of the content to which the dynamic download is applied among the contents that the user is subscribing to, and determines the content data to be dynamically downloaded accordingly.

In step S133, the mobile terminal 100 determines whether the user has visited or visited the area, such as the user's terminal usage pattern, the user's content subscription list, the user's schedule, the to-do list, Map data, route information, theme information, or POI information, and determines data to be dynamically downloaded accordingly.

In FIG. 6, the application data, the content data, and the data according to the user information are sequentially determined. However, the scope of the present invention is not limited thereto. For example, data according to application data, content data, and user information may be determined at the same time, or may be determined in a different order (e.g., in reverse order) than the order mentioned herein.

FIG. 7 is a flowchart further illustrating step S150 of FIG. Referring to FIG. 7, step S150 is embodied in steps S151 to S158.

When step S140 is completed in FIG. 5, step S151 of FIG. 7 is performed.

In step S151, the mobile terminal 100 (see FIG. 2) compares the size of the entire data included in the preliminary list with the size of the free space of the storage unit. If the size of the entire data is not larger than the free space of the storage unit, the dynamic download list determination method proceeds to step S152. Otherwise, the dynamic download list determination method proceeds to step S153.

In step S152, since the entire data included in the preliminary list can be stored in the storage unit, the mobile terminal 100 determines the entire data as data to be dynamically downloaded. When step S152 ends, the dynamic download list determination method proceeds to step S158.

Returning to step S151, if the size of the entire data is larger than the free space of the storage unit, the dynamic download list determination method proceeds to step S153.

In step S153, the mobile terminal 100 sets the reference value n to one.

In step S154, the mobile terminal 100 determines whether the highest priority data is cumulatively received in the free space of the storage unit, according to the priority of the data in the spare list. Specifically, from when n = 1, it is determined whether or not the data having the nth order of priority is accumulatively accommodated in the free space of the storage unit (i.e., all the data up to the nth can be accommodated in the free space of the storage unit). If it is acceptable, the dynamic download determination method proceeds to step S155. Otherwise, without determining the nth and subsequent data as data to be dynamically downloaded, the dynamic download list determination method proceeds to step S158.

In step S155, the mobile terminal 100 determines the n-th data as data to be dynamically downloaded. At this time, since the data to be dynamically downloaded is sequentially executed from the data having the first priority, when the n-th data is determined as data to be dynamically downloaded, data having a priority higher than that is also subjected to dynamic downloading.

In step S156, it is determined whether there is more data to be subjected to the dynamic download judgment in the spare list. If so, the dynamic download determination method proceeds to step S157. Otherwise, the dynamic download determination method proceeds to step S158.

In step S157, the mobile terminal 100 increments the reference value n by one. Then, the process returns to step S154 to determine the next data.

In step S158, the mobile terminal 100 generates and determines a dynamic download list according to the determined dynamic download data. Specifically, the mobile terminal 100 determines the final dynamic download list by updating or maintaining the spare list or creating a new download list according to the determined dynamic download data.

As an example, the mobile terminal 100 may notify the user by displaying a finally determined dynamic download list on the screen or by notifying the user through a message.

8 is a flowchart illustrating a method for dynamic downloading of data with reference to a dynamic download list, in accordance with an embodiment of the present invention. Referring to FIG. 8, the dynamic downloading method includes steps S210 to S270.

In step S210, the mobile terminal 100 is activated by turning on the power of the mobile terminal 100 (see FIG. 2) or returning from the standby state.

In step S220, the mobile terminal 100 automatically checks the location and current time of the mobile terminal 100. [

In step S230, the mobile terminal 100 determines data (or application or content) that has been used or data that is no longer to be used in the future based on the confirmed location and time information, I.e., data that has been used or will not be used in the future). The dynamic download list may be any one of the preliminary list, the updated preliminary list, or the newly created final download list described above in FIG.

For example, assume that the mobile terminal 100 included relevant data in the dynamic download list, according to a user schedule traveling on business that day on Monday. In this case, map data, route information, POI information, and theme information of Busan area will no longer be valid after Monday. At this time, the mobile terminal 100 deletes the corresponding data from the dynamic download list, thereby preventing unnecessary downloading. If some or all of the data has already been downloaded, the mobile terminal 100 can delete the downloaded data. In this case, however, the expired data can be adjusted so as not to be deleted by the user's setting or input.

In step S240, the mobile terminal 100 refers to the dynamic download list to determine whether there is data to be dynamically downloaded. If there is data to be dynamically downloaded, the dynamic download method proceeds to step S250. Otherwise, the dynamic download method ends.

In step S250, the mobile terminal 100 inquires the connection history which has successfully connected to the network at the current location or the neighboring location, and determines whether there is a connectable network environment at the current location. Here, the connectable network environment means a network environment that is allowed as a dynamic network environment according to the setting information. For example, if only the WiFi environment is allowed in the dynamic network environment in the setting information, the mobile terminal 100 determines whether the WiFi connection exists only in the possible network connection.

If there is a connectable network environment at the current location, the dynamic download method proceeds to step S260. Otherwise, the dynamic download method ends.

In step S260, the mobile terminal 100 connects to a connectable network environment. At this time, when there are a plurality of connectable dynamic network environments, the mobile terminal 100 tries to preferentially connect to the preferred network according to the network priority or preference. The network priority or preference may be determined automatically by analyzing the user's terminal usage pattern, or may be determined directly by user input. Step S260 is further specified in Fig.

In step S270, the mobile terminal 100 performs dynamic downloading through the connected network environment. At this time, the mobile terminal 100 can download the remaining data if there is a previously stopped download. When the mobile terminal 100 downloads all the data on the dynamic download list, the dynamic download method of the mobile terminal 100 ends.

According to the above configuration, the user can dynamically download necessary data through the low-cost and high-quality network environment by referring to the dynamic network list. Accordingly, the user can be provided with a better quality data transmission service at a lower cost. Further, the traffic of the mobile communication network can be reduced and the burden of establishing the mobile communication network of the communication carrier can be reduced.

FIG. 9 is a flowchart further illustrating step S260 of FIG. Referring to FIG. 9, step S260 is embodied in steps S261 to S264.

When step S250 is completed in FIG. 9, step S261 of FIG. 9 is performed.

In step S261, the mobile terminal 100 (see FIG. 2) confirms the past network connection history. For example, the mobile terminal 100 searches for a network connection that has been successfully connected in the past. At this time, the network environment to be searched means a network environment that is allowed as a dynamic network environment according to the setting information of the network environment that has been successfully connected in the past.

In step S262, the mobile terminal 100 determines whether there is a preferred network environment among the searched network environments. The preferred network environment means a network environment having a connection priority (or preference) determined according to a user input or a usage pattern of a user's terminal. If there is a preferred network environment, the flow advances to step S263. If the preferred network environment does not exist, the flow advances to step S264.

In step S263, the mobile terminal 100 accesses a preferred network environment to form a channel for dynamic download.

In step S264, the mobile terminal 100 connects to a connectable network other than the preferred network environment to form a channel for dynamic download.

FIG. 10 is a flowchart further illustrating step S270 of FIG. Referring to FIG. 10, step S270 is implemented in steps S271 through S275.

When step S260 is completed in FIG. 8, step S271 of FIG. 10 is performed.

In step S271, the mobile terminal 100 (see FIG. 2) determines whether there is data that has been interrupted during the previous download. If there is data that has been interrupted, the flow advances to step S272. Otherwise, the process directly proceeds to step S273.

In step S272, the mobile terminal 100 downloads the remaining data of the interrupted data. When the downloading of the remaining data is completed, the process proceeds to step S273.

In step S273, the mobile terminal 100 determines whether there is data to be newly downloaded. At this time, the mobile terminal 100 may determine whether to download data by referring to the dynamic download list. If there is data to be downloaded, the dynamic download method proceeds to step S274. Otherwise, the dynamic download method ends.

In step S274, the mobile terminal 100 refers to the dynamic download list and the priority of the data, and dynamically downloads new data.

In step S275, the mobile terminal 100 determines whether all data on the dynamic download list has been downloaded. If all data has been downloaded, the dynamic download method ends. Otherwise, the process returns to step S274 to further proceed with the download of the remaining data.
