The present invention relates to a portable terminal having a download function using a memory map and a method thereof, and more particularly, to download the rest data by downloading the remaining data following the currently downloaded data using the memory map when the download is restarted. It relates to a portable terminal and a method for providing the same.

In the present invention, the portable terminal is not only a wireless communication terminal such as a mobile communication terminal, a personal mobile communication terminal (PCS), a personal digital terminal (PDA), a smart phone, a next generation mobile communication terminal (IMT-2000), a wireless LAN terminal, etc. It refers to a portable terminal such as a Portable Multimedia Palyer) or an MP3P player.

In the present invention, a wireless communication terminal is a mobile communication terminal, a personal mobile communication terminal (PCS), a personal digital terminal (PDA), a smart phone, a next generation mobile communication terminal (IMT-2000), such as a wireless terminal while carrying a person A terminal capable of wireless communication.

In the following embodiment, a wireless communication terminal will be described as an example.

In the following embodiment, an external electronic device providing a file to be downloaded to the wireless communication terminal is a computer.

Of course, the present invention is not limited to this embodiment.

There may be various advantages of the wireless communication terminal, but above all, the greatest advantage is in the mobility provided to the user who is calling. Due to this mobility, the number of wireless communication subscribers has increased exponentially, and in recent years, wireless communication terminals are widely used by the general public.

However, as time goes by, the merits of mobility have gradually disappeared to users of wireless communication terminals, and a multifunctional wireless communication terminal capable of providing more various additional services is required.

Accordingly, most recently released wireless communication terminals have various functions such as camera function, radio broadcast reception function, music (for example, MP3: MPEG layer 3) playback function, acupressure function, blood glucose detection function, ultrasonic imaging function, etc. It has a function. In particular, the music playback function is one of the additional features that are in the spotlight of the young generation.

On the other hand, in order to play music in the wireless communication terminal as described above, by connecting a wireless communication terminal and a computer, a computer downloads and plays a music file in a format that can be played in the wireless communication terminal.

On the other hand, when the music file is downloaded from the computer to the wireless communication terminal as described above, the download is not completed according to the state of the computer, the state of the wireless communication terminal or the state of the data communication cable connecting the computer and the wireless communication terminal. There is a time to stop.

If this happens on your computer, you can take over.

As such, when the downloaded content (mp3, video, picture, etc.) is downloaded to the memory and broken in the middle, the downloaded size is calculated and the remaining part is downloaded.

This will be described with reference to FIG. 1.

If the file is interrupted while downloading, the download is not completed. Therefore, check how many files are downloaded in memory. For example, if the total size of the file is 5000KB and the size of the currently downloaded file is 3000KB, the file that has not been downloaded yet is 2000KB out of the total 5000KB, and thus downloads the remaining 2000KB files to complete the download.

However, it is a problem to inherit the file in the memory of the wireless communication terminal in such a manner.

This is because, when downloading a file, the wireless communication terminal uses the memory by dividing it into necessary areas rather than continuously using the memory like a computer.

This will be described with reference to FIG. 2.

When a total of 5000KB files stored in the computer are downloaded to the wireless communication terminal, files stored from address 0 (0x0) to address 1000 (0x1000) in the computer memory are stored from address 0 (0x0) to 1000 in the wireless communication terminal memory. Files downloaded to address (0x1000) and stored from address 1000 (0x1000) to address 5000 (0x5000) in the computer memory are the same as those downloaded from address 3500 (0x3500) to address 5500 (0x5500) in the wireless communication terminal memory. The file is downloaded.

Therefore, the following problem occurs when the download is completed through the download of the file as described above.

For example, if only 500 KB of the 5000 KB file is downloaded and the download is interrupted due to an external factor, the remaining 4500 KB files will be downloaded when the remaining file size is downloaded and calculated as follows. 500 to 5000 addresses of the wireless terminal memory are downloaded.

Therefore, the wireless communication terminal memory does not reflect the characteristic of dividing the necessary files by area and writing the file according to the area, and calculates only the size of the file not downloaded in the same way as the computer. Downloading may cause the wireless terminal to malfunction.

The present invention has been proposed to solve the above problems, and provides a portable terminal and a method for providing a download download function by downloading the remaining data following the currently downloaded data using a memory map at the download restart. There is this.

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.

On the other hand, the method of the present invention, in the download method using a memory map in the portable terminal, the start address, the last address of the external electronic device storage means for providing a file to download, the start address of the portable terminal storage means, the last Storing an address, a size of a block, and a download completion flag in the form of a memory map mapped to a block of each storage means; Receiving a download restart signal; Identifying a block of the portable terminal storage means to start receiving with reference to a download complete flag of the information in the memory map; Checking a size of a file currently downloaded to the checked block; Calculating an address of the external electronic device storage means in which a next part of the currently downloaded file is stored with reference to the checked current downloaded file size and the start address of the external electronic device storage means in which the file is stored; And restarting the download from the file stored at the address of the calculated external electronic device storage means.

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.

3 is a block diagram of an embodiment of a wireless communication terminal having a download download function using a memory map according to the present invention.

As shown in FIG. 3, the wireless communication terminal having the download download function using the memory map according to the present invention includes a wireless transmission / reception unit 350 for transmitting / receiving a signal (including download data) through a wireless communication network. Connection unit 390 for receiving a file from an external electronic device, a storage unit 320 for storing download-related information in the form of a memory map matched with a block divided into a plurality of areas, and transmitted through the connection unit 390 When restarting the download of the received file to the storage unit 320, the controller 310 and the controller 310 for downloading the remaining files following the currently downloaded file by referring to the download-related information stored in the memory map form. A display unit (LCD) 340 for displaying the download process under control of the control unit, an input unit for receiving a download restart signal through a button (keypad 330, under the control of the controller 310, converts the signal received from the wireless transmitter / receiver 350 into voice and outputs it to the voice output unit (speaker) 380, and the voice input unit (microphone) 370 Codec (360) for converting the voice input from the signal to the control unit 310 to be transmitted through the wireless transmission and reception unit 350, and outputs the voice received from the codec (CODEC) 360 A voice output unit (speaker) 380 for receiving, and a voice input unit (microphone) 370 for receiving the voice and deliver it to the codec (CODEC) (360).

In addition, the storage 320 stores an operation program and a system program of the controller 310, and the operation program and the system program are stored in a normal ROM area and can be erased as necessary. The storage unit 320 also includes a RAM for temporarily storing data generated during execution of various operation programs.

In addition, the storage unit 320 may include a start address, a last address of a computer memory providing a file to be downloaded to each block, a start address, an end address, and a block size of the wireless communication terminal memory from which the file is downloaded. ) And the download complete flag are stored in the form of a matched memory map according to each block.

The input unit (keypad) 330 is composed of a plurality of numeric keys (letter keys), menu keys, and function keys for performing various functions, and outputs key data to the controller 310 by external operations. do.

The display unit (LCD) 340 is a display device such as a liquid crystal display (LCD). The display unit (LCD) 340 is controlled by the control unit 310 to display a state of a wireless communication terminal, a progress of a program, a download process, and the like. That is, the overall state of the wireless communication terminal and the contents received through the input unit (keypad) 330 are displayed.

The controller 310 controls the overall operation of the wireless communication terminal and each component. In addition, the controller 310 refers to the memory map of the storage unit 320 and stops downloading a file to the wireless communication terminal memory due to an external factor and restarts the input unit (keypad) 330. In response to receiving the download restart signal, it controls to download the next file after the currently downloaded file without re-downloading the file from the beginning.

This will be described in more detail with reference to FIG. 4 as follows.

First, the area from address 0 (0x0) to address 1000 (0x1000) among blocks stored in the computer memory is called block 2, and the area from address 1, address 1000 (0x1000) to address 5000 (0x5000) is called block 2, and the wireless The area from the communication terminal memory address 0 (0x0) to the address 1000 (0x1000) is the block 2 from the blocks 1, 1500 (0x1500) to 5500 (0x5500).

And, it is assumed that the file stored in the computer memory block 1 is downloaded to the wireless communication terminal memory block 1, and the file stored in the computer memory block 2 is downloaded to the wireless communication terminal memory block 2.

There is a memory map in which file download related information is matched for each block.

For example, information about block 1 of the memory map indicates a start address and an end address of computer memory block 1, a start address and an end address of block 1 of the wireless communication terminal memory, and whether the download of block 1 is completed. The download completion flag for the bet and the total size of the block 1 are included.

Meanwhile, the download complete flag is set to an initial value of 0, and is reset to 1 when the file is completely downloaded to the block.

Similarly, the same information is stored for block 2 as well.

Thus, when the download is interrupted due to an external factor during download and restarted, the controller 310 may refer to the memory map stored for each block so as to determine a block and a memory address to inherit.

For example, suppose that a file is interrupted by an external factor while the file is downloaded to block 2 having a total size of 4000 KB.

In this case, the controller 310 examines the download complete flag of the block from which the download was interrupted so as not to download from the beginning but to continue from the next part of the currently downloaded file.

This is because, even if the download is interrupted while the file is being downloaded, the block 2 may be stopped at almost the same time as the file download of the block 2 is completed, or the download may be stopped without completing the file download. In the case of the former, the download complete flag is reset to 1, and in the latter case, the download complete flag will be set to 0, which is an initial value.

On the other hand, when the download completion flag of the memory map matched with block 2 is 0 as described above, the controller 310 is the file size currently downloaded to the block 2 and the information of the memory map matched with block 2 When restarting the download with reference to the start address of the computer memory in which the file to be downloaded in block 2 is stored, the address of the computer memory in which the file to be downloaded is stored is calculated.

For example, when the size of the file currently downloaded in the block is 400KB and the start address of the computer memory in which the file is downloaded in the block is 1500KB, the controller 310 continuously follows the downloaded file. The address of the computer memory in which the file to be downloaded is stored is calculated as 1900KB.

Subsequently, the file stored in the address of the computer memory calculated as described above is downloaded to be continuously connected to the currently downloaded file.

5 is a flowchart illustrating a method for downloading a download using a memory map in a wireless communication terminal according to the present invention.

First, a file download process is interrupted due to an external factor while a computer and a wireless communication terminal are connected by a data communication cable and the file stored in the computer is downloaded to the memory of the wireless communication terminal (510).

Subsequently, in response to receiving the download restart signal through the input unit (keypad) 330, the controller 310 checks the download completion flag in the memory map matched with the block in which the current file download is stopped (520).

As a result of the check 520, if the value of the download complete flag is not 0, the download is stopped from the next block because the download is interrupted by an external factor at about the same time as the file download process is completed in the block where the current download is interrupted. The process restarts (540).

On the other hand, if the result of the check 520, the value of the download complete flag is 0, since the file download process of the block where the current download is interrupted is not completed, the controller 310 is continuous to the currently downloaded file at the download restart In operation 550, an address of a computer memory in which a file to be inherited is stored is calculated.

In this case, the controller 310 refers to the start address of the computer memory in which the file downloaded to the block is stored among the size of the file currently downloaded to the block and the information of the memory map matched to the block.

Then, the download is restarted from the file stored at the address of the computed computer memory (560).

As described above, since the download is interrupted and the download is not restarted from the beginning, the time required for the download can be reduced by downloading after the interrupted portion.

In addition, even if the download cannot be continued due to the overload of the wireless communication terminal or the computer or the operator's circumstances, the download can be arbitrarily interrupted and the download can be restarted from the interrupted part.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily carried out by those skilled in the art will not be described in more detail.

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.

As described above, the present invention has the effect of being able to download by downloading using a memory map.

In addition, the present invention has the effect of reducing the time required to download, when the download is interrupted by restarting by providing a download function as described above.

In addition, the present invention provides a resume download function as described above, even if the download can not continue because of the overload of the system or due to the operator's circumstances, after stopping the download arbitrarily, restart the download from the interrupted portion It can be effective.
