Title: 전화기를 사용한 개인 인터넷폰 통화 시스템
Filed: 1999-08-30
Abstract: 본 발명은 인터넷 상에서 이루어지는 인터넷 폰 통화를 자체 e폰박스(가칭) 이라는 H/W 장치를 통해 자동화하는 시스템(가칭 e폰시스템)과 그 방법에 관한 것으로, 더욱 상세하게는 사용자가 인터넷을 통해 전화통화를 하기 위해 필요했던 H/W 및 S/W 장치들을 e폰박스라는 장치 안에 전부 내장함으로써 일반 사용자들은 인터넷폰을 사용하기 위한 컴퓨터 또는 네트워크 및 인터넷폰에 대한 기초 지식 없이도 인터넷을 통한 전화서비스를 편리하게 사용할 수 있도록 처리해주는 시스템 및 그 방법에 관한 것이다. 
     이를 위하여 본 발명은 e폰박스라는 기계 안에 인터넷폰에 필요한 H/W및 S/W 모듈을 넣어서 하나의 장치로서 캡슐 화한다. 또한, 이 장치는 인터넷 연결을 위하여 전화선을 통한 모뎀 또는 LAN으로 직접 연결 가능하며, 사용자들의 편리한 사용을 위한 사용자 인터페이스로서 일반 전화기와 연결한다. 
     이로써 사용자는 e폰박스을 기존의 전화기와 전화단자 혹은 LAN단자와 연결한 후, e폰박스와 연결된 전화기의 다이얼링만으로 전세계 누구와도 손쉽게 통화할 수 있는 시스템인데, 이는 사용자에 있어서 인터넷 통화에 필요한 인터넷 접속 및 연결설정 그리고 음성과 데이타의 변/복조화등 필요한 모든 과정들이 e폰박스 내부에서 자동화되어 이뤄짐으로써 가능하다. 
     이에 따라, 전세계 서로 다른 상대방을 구별하여 전화통화를 하기 위해서는 상대방을 확인 및 식별하기 위한 식별 체계가 필요한데, 이를 위해서 본 발명에서는 e전화번호라는 독립적인 번호체계를 만들었다. e전화번호는 기본적으로 모든 e폰박스에 독립적으로 하나씩 주어지는데, 꼭 e폰박스 소유자가 아닌 경우에도 별도의 신청절차에 따라 e시스템에서 희망자에게 직접 e전화번호를 부여할 수 있다.  이는 e폰박스 시스템에서 통화가 e폰박스 시스템 사용자간에만 이뤄지지 않고, e폰박스 소유자와 일반PC사용자간의 통화를 위해 필요하다. 
     상기에서 본 발명에서 고안한 e폰시스템에서 사용하는 e전화번호는 독립적인 번호 체계로써, 이는 기존의 전화망 번호와 다르다. 따라서, 기존의 전화망 전화번호를 사용하던 사람들이 새로운 전화번호를 익혀야 하는 등 사용상의 불편함을 가질 수 있는데, 이를 개선하기 위하여 기존에 사용 중이던 전화망의 국제식별 전화번호 (예: 국가코드-지역코드-국번-전화번호의 차례로 이뤄진 국제적인 유일한 전화번호)를 e폰서버 혹은 e폰박스에 등록, 저장해두면, 이는 나중에 자동으로 해당 국제식별전화번호와 연계된 e전화번호를 찾아서 e폰박스에 알려줌으로써 상대방의 e전화번호를 굳이 알아두지 않아도 예전의 전화번호 체계와 호환성이 유지된다. 
     e폰시스템에서 전화통화는 다음과 같이 이뤄질 수 있다. 첫 번째로, e폰박스 소유자와 e폰박스 소유자간의 통화가 이뤄질 수 있고 둘째로, e폰박스 소유자와 일반PC  사용자간의 통화가 이뤄질 수 있으며 마지막으로 e폰박스 소유자와 일반전화 사용자간의 통화가 이뤄질 수 있다. 
     상기에서 e폰박스 대 e폰박스 통화의 경우, 먼저 사용자가 e폰박스와 연결된 전화기에서 상대방의 e전화번호 또는 국제식별 전화번호를 다이얼 하면, 해당 번호는 e폰박스에 의해 해석되어 메모리에 저장되어 있는 데이타인지를 확인 후, 저장되어 있는 전화번호라면, 해당 국제식별전화번호의 e전화번호 및 상대방의 최근 접속 IP주소를 메모리에서 찾아본 후, 해당 IP로 사용자확인 과정을 거친다. 사용자 확인 절차는 상기의 IP주소로 접속후 해당 IP주소에 접속되어 있는 사용자의 e전화번호가 메모리의 e전화번호와 같은지를 확인하는 작업으로써, 만일 같을 경우 같은 사용자가 계속 해당 IP주소를 사용중인 것으로 판단하여 전화 통화가 이뤄지도록 하며, 다를 경우 이는 통화하고자 하는 상대방의 IP주소가 변경된 것으로 판단하여, e폰서버에 문의하여 최신 데이터를 가져온 후 위와 같은 사용자 확인 작업을 다시 한번 거친다. 그런데, 처음에 다이얼 했던 전화번호가 e폰박스의 메모리에 저장되어 있지 않은 경우일 때도 마찬가지로 e폰서버에 문의한 후, 사용자 확인 작업을 거치게 된다.
