Filed: 2000-07-29
Abstract: PURPOSE: A communication method and system for singing practice players using a VPDN(Virtual Private Dialup Network) is provided to ensure stability in communication speed, to freely operate IPs and to strengthen security by using an authentication server and a tunneling technique in case that a server transmits new contents to singing practice players installed in each sing room. CONSTITUTION: A singing practice player makes a phone call to a PPP server and attempts communication access in order to download musical contents from a server(S1). If communication connection is made between the player and the PPP server(S2), the player transmits its own ID and domain name to the PPP server(S3). The PPP server transmits the transmitted ID and domain name to an authentication server(S4). The authentication server transmits the address of a router allocated to the domain name to the PPP server after authenticating the ID and the domain name(S5,S6). The PPP server attempts access to the router through a backbone network(S7). If communication connection is made between the PPP server and the routers(S8), the server grants a virtual IP to the singing practice player(S9). Accordingly, a communication tunnel directly connecting between the player and the server is formed. The player downloads necessary musical contents from the server through the communication tunnel without the necessity of going through the authentication server(S10,S11).
