Abstract:
1. A communication relay system, comprising: at least one terminal for attempting communication over a communication network using access information and transmitting terminal identification information together with the access information; at least one service providing server for providing service through a communication path set up over an Internet network; and a communication relay server for setting up the communication path between the terminal and the service providing server, wherein the communication relay server accesses a database storing records, including pieces of user information, terminal identification information, access information, and service identification information and path IDs, pieces of either communication path setup information and checks the terminal identification information and the access information being received from a first terminal attempting communication based on the access information managed by the communication relay server, wherein the communication relay server searches the database for a record including the terminal identification information and the access information, and wherein the communication relay server extracts a record, having identical user information to user information corresponding the record retrieved from the database; and wherein the communication relay server checks whether there is a second terminal to which a communication path has been set up based on communication path setup information about the record extracted, if as a result of the check, the second terminal to which the communication path has been set up does not exist, performing a communication path setup process for the first terminal, and if, as a result of the check, the second terminal to which the communication path has been set up exists, performing the communication path setup process for the first terminal, and blocking the communication path to the second terminal.
