KR20020084966A - Synchronizing method for having priority - Google Patents

Abstract

PURPOSE: A method for the synchronization with a priority is provided to increase the synchronization speed by carrying out the synchronization through a device of the priority with the fastest speed, and to efficiently use a function of the system without a loss by efficiently using the optimal device usable to the system. CONSTITUTION: At a synchronization mode, a hardware device of the system is checked and the operation of a software drive is checked. According to a check result of the hardware device, a synchronizable device flag is sent to a confront system. After recognizing the synchronizable device flag, a communication mode is fixed to one with a high priority among the modules communicating with each other. The synchronization is carried out by using the fixed communication mode. At the time of checking the hardware device and the software drive operation, a LAN module with the fast speed is firstly checked before a USB(Universal Serial Bus) module and a serial module is lastly checked.

Description

Synchronization method with priority {SYNCHRONIZING METHOD FOR HAVING PRIORITY}

The present invention relates to a synchronization method having a priority, in particular the system and the surrounding environment by using all devices that can be synchronized in one system to send and receive data from PC and PC or PC and portable terminal or portable terminal and portable terminal, etc. The present invention relates to a synchronization method having a priority of accelerating the synchronization speed by performing synchronization according to the priority.

Recently, devices that synchronize through USB (Universal Serial Bus) are emerging. However, all of these have only one synchronization function in one system, which will be described below with reference to the accompanying drawings.

FIG. 1 is an exemplary diagram for describing a conventional synchronization method using serial. When serial exists in both systems to be synchronized, as shown in FIG. 1, the serial synchronization is performed.

FIG. 2 is an exemplary diagram for describing a synchronization method using a conventional USB. As shown in FIG. 2, when the USB exists in both systems to be synchronized, the USB is synchronized.

By the way, if both the serial and the USB are present on both systems to be synchronized, if the serial is to be synchronized, it is not using the system efficiently.

In other words, the prior art operating as described above has a problem in that performance is poor due to synchronization using serial, and there is a problem in that there is a device having a speed other than serial in the system.

Accordingly, the present invention has been made in view of the above-mentioned problems, and includes a system using all devices capable of synchronizing in one system for transmitting and receiving data from PCs, PCs, PCs and portable terminals, and portable terminals and portable terminals. The purpose of the present invention is to provide a synchronization method having a priority that speeds up the synchronization speed by matching synchronization with the surrounding environment.

In order to achieve the above object, the present invention provides a first step of checking a hardware device of a system and checking whether a software drive is operating in a synchronous mode, and a device flag that can be synchronized according to the hardware device check result of the first step. A second step of transmitting to the opposite system, a third step of setting a communication mode with a higher priority among modules that can recognize the synchronous device flags from the second step and communicate with each other; and And performing a fourth step of performing synchronization using a communication mode.

Hereinafter, operations and effects on the synchronization method having priority according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 5 is a flowchart illustrating a procedure of a synchronization method having priority according to the present invention. As shown therein, a first step of checking a hardware device of a system and checking whether a software drive is operating in a synchronous mode, and the first step According to the hardware device check result of the second step of transmitting the synchronous device flag to the other system and the module that can recognize the synchronous device flag from the second step and communicate with each other, the highest priority The third step of setting and the fourth step of performing synchronization by using the communication mode of the third step is described as follows.

First, in order to synchronize between two systems, one system first checks a hardware device attached to the system in the synchronous mode to determine which device to synchronize with.

Here, when checking the hardware device, the fast LAN hardware module is checked first, then the USB hardware module, and finally, the serial hardware module.

3 is an exemplary view showing the contents of the system used in the present invention. As shown in FIG. 3, when both the LAN, the USB, and the serial are present in both systems to be synchronized, it is fastest to synchronize the system through the LAN. Is to use.

When the hardware device check is completed, it checks whether the software drive is operating. In this case, it checks the LAN software module, then the USB software module, and then the serial software module.

In the above, when the hardware and software check is completed, that is, when the check of the device capable of being synchronized in the system is completed, the device flag available to the other system is informed.

Then, the other device performs the same process as above and informs the other device of the available device flag. Accordingly, the device having the fastest priority among the modules that can be used in both systems and can communicate with each other is communicated. Set to mode.

Synchronization is performed through the communication mode set above, that is, the communication mode with high priority.

As described in detail above, the present invention wastes the functions of the system because it speeds up the synchronization speed by performing the synchronization through the device having the highest speed and efficiently uses the optimum device that can be used in the system. It can be used effectively without the effect.
