BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a download system for a portable terminal, and more particularly to a download system for a portable terminal that provides an independent multi-port for program download of the portable terminal.

Recently, the USB interface method applied to a mobile phone is used not only for transmitting user data of a user, but also for downloading and program upgrade of terminal software during production of the terminal. It is also usefully used in post-production work and after-sales service.

1 is a block diagram showing a conventional download system for a mobile terminal.

Referring to FIG. 1, in order to transmit terminal software to a terminal 50 from a computer PC 10, a hub 20 and 30 having a plurality of ports are connected to the computer 10, and the hub ( The terminal interface 40 is connected to each of the ports 20 and 30.

Here, the hubs 20 and 30 are USB hubs 20 of the USB type or multi-serial (RS-232) port hubs 30 of the USB type, depending on the method of connection with a computer, and each hub 20. 14 ports are usually assigned to 30.

In addition, the terminal interface 40 is connected to the hubs 20 and 30, and includes a plurality of connectors C1 to C14 and 41, and each of the connectors C1 to C14 41 and the mobile terminal 50. ) Is connected to the cable (42).

Therefore, the hubs 20 and 30 are connected to the computer ports so that the software can be downloaded to the plurality of portable terminals 50 through the USB 1 port or the COM-RS 1 port 1 of the computer 10. . The software is transmitted to the terminal interface unit 40 through the hubs 20 and 30 connected to the computer 10, and the software download operation can be performed on the plurality of portable terminals 50 through the terminal interface unit 40. It becomes possible.

Here, in the production of the portable terminal, the program of the software required for the terminal is downloaded by connecting to the hub (RS-232 or USB hub) connected to one computer 10 in multiple (14Port) for reasons such as increased production and cost reduction. .

At this time, in the conventional method using the RS-232 hub 30 or the USB hub 20, the transmission speed is more than a certain number of ports (channels) in a predetermined number or more. For example, in the RS-232 hub 30, 40 minutes are required to transmit 10 Mbytes of mobile terminal software data from the computer 10. In the case of the USB hub 20, it takes 18 minutes to transmit 10 Mbytes.

However, when using multiple channels, a single USB transmission line is shared by the number of nodes connected to the maximum USB transmission speed. Therefore, the speed is productivity to perform software download tasks of multiple mobile devices to a single computer using a USB hub. There is a problem that is hard to help improve.

Therefore, when using a hub, the transfer speeds of the USB bus and the RS-232 communication bus are drastically reduced by using a plurality of ports. In addition, there is a space loss and wiring / wiring problems due to the use of a hub of a USB port or an RS-232 port.

At the same time, when a download operation is being performed on a plurality of portable terminals, the terminal to be downloaded first or a port in which an error occurs during the download cannot be restarted or replaced until all ports of the same task are completed.
