TECHNICAL FIELD The present invention relates to a data management system using a link aggregation module and a data management system using the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data management system and method using a link aggregation module, and more particularly, to a data management system using a link aggregation module and a data management apparatus for managing data communication between a data control apparatus and a plurality of peripheral apparatuses, By using the link aggregation module for integrating the connection of the wireless communication channel into one logical communication channel, it is possible to compensate the connection break due to the change of the communication environment such as the sudden change of the communication position, And more particularly, to a data management system using a link aggregation module and a method thereof for providing persistence.

BACKGROUND OF THE INVENTION In general, modern computing devices such as personal computers (PCs), laptops, and personal digital assistants (PDAs) Such as a modem, which enables communication via an interface such as a Division Multiple Access (GPRS), a General Packet Radio Service (GPRS), or a Universal Mobile Telecommunications System (UMTS) or the like.

An operating system (OS) running on such a computing device is typically a software application client such as a Connection Manager Client that uses the communication capabilities provided by the data communication device to send and receive data. ).

The data communication device itself may comprise a network access service for accessing the network system state, a wireless data service for transmitting and receiving data over a wireless link, and a device management service for accessing device identification and power level status , And provide a number of services to a software application running on the computing device.

Physically, the communication between the computing device and the data communication device may be via a physical interconnect such as, for example, a serial bus including USB, RS-232, PCI, and PCMCIA, or a wireless interface including Bluetooth and IEEE 802.11. Lt; / RTI >

In the case of a higher-layer communication, i.e., a client-service interface, between an application client running on a computing device and a service running on a data communication device, the protocol used in the prior art is a W-CDMA 3GPP terminal (Refer to 3GPP TS 27.007 V3.13.0 (2003), published in 1999) and CDMA 3GPP2 terminal (see 3GPP2 C.S0017-003-A, "Data Service Options for Spread Spectrum Systems: AT Command Processing and the Rm Interface" (RNDIS), and Universal Plug and Play (UPnP).

Recently, computing devices support an increase in the number of communication applications, while data communication devices can support more and more communication technologies. For example, a laptop computer may run a communications application such as a web browser, e-mail, and calendar synchronization using a modem that supports Bluetooth, IEEE 802.11, and CDMA.

On the other hand, in the case of a personal computer (PC), there are a variety of controllers that can control external devices, and through which the main controller (CPU) communicates with peripheral devices (or external devices) Recently, in the embedded device, it has a form like a star topology in which peripheral devices are directly controlled by the main controller.

Herein, the star topology refers to a form in which a plurality of small computer systems are connected to a central computer in the center, and small computer systems communicate with other computers through a main computer, and usually share a database (DB) Distributed computer systems are all connected to terminals so that any terminal can communicate with other terminals in the network.

However, in the configuration of the star topology type of the above-mentioned embedded device, the load on the main controller (CPU) is heavy, and time, effort, and cost of commercialization are increased. In particular, there is a disadvantage that technical support such as addition of a register to support various interfaces of various devices that can be connected to the main controller (CPU) must be followed, and further efforts due to various developments of various non-standardized interfaces must be continued .

In particular, when using peripherals that are not supported by the embedded system-on-a-chip (SoC) or peripherals that use an unsupported bus, you must use a SoC change or add-on module, (H / W) and software (S / W) due to the increase in cost and verification time.
