Abstract

Disclosed herein is a system for automatically upgrading the firmware of Internet video phones and a method of managing the system. The system includes one or more Internet video phones, an upgrade server, and a Trivial File Transfer Protocol or Hypertext Transfer Protocol (TFTP/HTTP) server. Each of the Internet video phones has information, including a company name, a language type, a version and an Internet Protocol (IP) address, and transmits information, including changed IP information, via an Internet when the IP information changes. The upgrade server performs an update using information transmitted from the Internet video phones and transmits upgrade commands to the Internet video phones when new firmware is distributed. The TFTP/HTTP server transmits the new firmware, which is requested by the Internet video phones in response to the upgrade commands, to the Internet video phones that requested the firmware.

Claims

1. A system for automatically upgrading firmware of Internet video phones, comprising:

one or more Internet video phones each configured to have information including a company name, a language type, a version and an Internet Protocol (IP) address, and to transmit information including changed IP information via an Internet when the IP information changes;

an upgrade server for updating information transmitted from the Internet video phones and transmitting upgrade commands to the Internet video phones when new firmware is distributed; and

a Trivial File Transfer Protocol or Hypertext Transfer Protocol (TFTP/HTTP) server for transmitting the new firmware, which is requested by the Internet video phones in response to the upgrade commands, to the Internet video phones that requested the firmware.

2. The system as set forth in claim 1, further comprising an upgrade Database (DB) that communicates with the upgrade server and stores information on the Internet video phones, including the changed IP information.

3. A method of managing a system for automatically upgrading firmware of Internet video phones, the system having one or more Internet video phones, an upgrade server connected to the Internet video phones via a network to transmit firmware upgrade messages to the Internet video phones, and a TFTP/HTTP server connected to the Internet video phones via a network to transmit the firmware;

the method comprising the steps of;

the first step of transmitting a company name, language information, a version and IP information from the Internet video phones to the upgrade server;

the second step of updating the upgrade server using the transmitted information;

the third step of transmitting upgrade commands to the Internet video phones when new firmware is distributed;

the fourth step of transmitting firmware requests from the Internet video phone to the TFTP/HTTP server; and

the fifth step of transmitting the firmware from the TFTP/HTTP server to the Internet video phones in response to the firmware requests.

4. The method as set forth in claim 3, further comprising, before the first step, the step of transmitting changed IP information to the upgrade server when the IP information of the Internet video phones changes.

5. The method as set forth in claim 3, further comprising the step of periodically informing one or more of the Internet video phones of the upgrade of the firmware by periodically transmitting upgrade messages if the firmware requests are not made by the one or more Internet video phones.

6. The method as set forth in claim 4, further comprising the step of periodically informing one or more of the Internet video phones of the upgrade of the firmware by periodically transmitting upgrade messages if the firmware requests are not made by the one or more Internet video phones.
