The present invention relates to a portable mass storage system using a wireless communication network, the prior art in the technical field to which the present invention belongs.

1. Portable storage  Device related:

Flash Memory type storage system such as USB Memory Drive is small and convenient to carry, but the general storage capacity is 1 ~ 2Gbytes small and expensive, and it is impossible to recover data in case of loss or failure.

In addition, magnetic disk-type HDD drive systems such as external hard disks have a storage capacity of more than 20Gbytes and are inexpensive, but they are impossible to recover data from when they are lost or broken.

2. Internet environment storage  System related:

Data is backed up to a remote storage server system using the Internet to ensure safety, and the storage capacity is very large because it is a local system rather than a portable system. However, the data must be backed up by logging in to a separate server, and the data backup is not possible in an environment without internet connection.

3. Mobile Internet and Wireless Communication:

The portable Internet is a service that enables high-speed wireless Internet access anytime, anywhere, and on the go, and it is characterized by overcoming the space limitations and mobility of wired high-speed Internet and wireless LAN. The mobile internet succeeded in developing and demonstrating technology for the first time in the world in December 2004, centering on ETRI.

This service technology adds portable mobile capability to WiMax technology, a fixed broadband wireless access interface standard of IEEE 802.16. WiMax stands for "Worldwide Interoperability for microwave Access," and IEEE 802.16e supports mobile standards as well as fixed broadband. Therefore, mobile Internet standard technology is commonly referred to as Mobile WiMAX technology. Especially, in Korea, service has been started since the first half of 2006 under the name of Wibro (Wireless Broadband Internet).

The portable Internet can be divided into basic functions and advanced functions in terms of bandwidth efficiency and major technologies in terms of element technology. Being wireless rather than wired, the basic technologies include spreading codes or timeslots, diversity to mitigate propagation conditions, power control, intercell handoff, and location registration to support roaming.

More advanced features include Orthogonal Frequency Division Modultion / Orthogonal Frequency Division Multiple Access (OFDM / OFDMA), Multi-Input-Multi-Output (MIMO), Adaptive Modulation and Coding (AMC), Hybrid Automatic Repeat reQuest (HARQ), Packet Scheduling Dynamic bandwidth reservation techniques are being provided.

From the standpoint of standardization, 802.16e / WiBro evolved from 802.16, which was intended for fixed wireless, 802.20 being standardized for mobile use, and 3GPP Long Term Evolution (LTE.6) since 3GPP are the leading portable Internet standard technologies.

The background of the emergence of the portable Internet first in Korea can be summarized as follows.

First, with the expansion of notebook PCs and low-cost wireless LAN equipment, there is an increasing number of cases of free access to the Internet wirelessly even in ASDL-based homes.

Second, with the provision of hot spot services through public wireless LANs such as the existing Net-spot, 11Mbps-class wireless Internet access is possible in public places using portable computing terminals such as notebook PCs and PDAs.

Lastly, monthly billing is possible by supplying low-cost wireless LAN equipment, which reduces the burden on charges as in existing wired high-speed Internet.

As a result, the mobile Internet has been distinguished from the existing information and communication services because the mobile service has a big advantage for consumers because it is a mobile data service that can stably supply real-time multimedia contents such as ADSL.

4. Specific examples of wireless communication technology:

1) WiBro

Currently, KT is the world's first wireless portable Internet service, which means Wireless Broadband Internet. Just as you can use your phone anywhere, anytime WiBro can use the Internet anytime, anywhere. The frequency band is 2.3GHz, the Internet speed (service bandwidth) is about 1Mbps, and it can be serviced without cutting when moving below 60km per hour. It is at the heart of the IT839 policy of the Ministry of Information and Communication, and is famous for being named with affection by former Minister of Information and Communication.

2) HSDPA / HSUPA

As the name of High Speed Downlink Packet Access indicates, WCDMA 3G technology has a specially increased downlink download packet speed. Its download speed is 1 ~ 2Mbps, upload speed is 384kbps, and it is a global standard technology using 2.0Ghz frequency. In March 2007, the nationwide network service began in Korea. HSUPA is a service that not only download speed but also upload speed.

3) EVDO (EVolution Data Only)

It is a CDMA-based technology that is widely used as 2G-based 1X technology, and it only increases dataload speed and adds usefulness in downlink packet down. But the download speed is about 300kbps, slower than other technologies.

The present invention has been proposed to solve the problems of the prior art as described above and at the same time to take advantage of the prior art, it is small in size as a conventional portable storage device is ensured portability and at the same time data to a remote storage server It is an object of the present invention to provide a portable mass storage system using a wireless communication network that can safely protect data even when a portable storage device is lost or broken due to backup.

Mediate.

Portable mass storage system using a wireless communication network according to the present invention preferably further comprises a user authentication server 500 and subscriber information DB (600).

In this case, when a system user reads or writes a file existing on a network drive of a remote mass storage server 200 mapped to a local drive of the computer 100, the network drive Read / Write program block 340 may execute a client user authentication program. The relevant information including the login information of the system user generated by the block 320 is transmitted to the remote user authentication server 500 via the mobile Internet network and the public Internet network, and the login information received by the user authentication server 500 is analyzed. As a result, if the information exists in the subscriber information DB 600, the user authentication server 500 grants the system user the right to access the network drive of the remote mass storage server 200. do.

Meanwhile, the remote mass storage server 200 and the user authentication server 500 according to the present invention are implemented on the Internet through a cooperative operation between a client requesting a service and a server processing a client's request. It is a concept of a general web server that provides a request of the computer 100 through a wired / wireless network in a distributed client / server manner in which one or more application programs are operated in a cooperative environment so that a client may obtain a desired result.

The web servers described above are operating systems such as DOS, Windows, Linux, UNIX, Mac OS, OS / 2, Solaris, etc. It can be implemented by using various web server programs provided according to the example. The representative ones are PWS (Personal Web Server), Internet Information Server (IIS), Website (TTPS) and Unix environment used in the Windows environment. CERN, NCSA, and APPACHE used in

However, the remote mass storage server 200 and the user authentication server 500 in the form of a web server include a series of application programs for providing various services according to the present invention, in addition to the web server program in a conventional sense. It should be understood as a broad concept.

The above description is merely illustrative of the technical idea of the present invention, and various modifications, changes, and substitutions may be made by those skilled in the art without departing from the essential characteristics of the present invention. will be.
