본 논문에서는 이동통신 3사의 무선인터넷 서비스 시스템의 패킷 과금방식에 대하여 과금체계 검증시험을 실시하여 측정용 파일크기와 사업자의 과금데이터를 비교 분석하였다.검증시험 결과에 나타난 바와 같이 이동통신사의 무선환경에 영향을 받는 망 품질에 따라서 과금데이터가 전송 오버헤드들로 인하여 차이가 발생되고 있어, 이동통신사간의 통일된 패킷의 과금적용을 위해 패킷 분석시스템을 제안하였다.과금시스템에 패킷 분석시스템을 추가하여 보완하면, 서비스별 프로토콜 분석을 통해 패킷 데이터를 추출하고 트래픽 데이터를 분석하여 콘텐츠 유형별 분류할 수 있어 이동통신사간의 패킷별 과금적용 및 콘텐츠 가치에 기반한 차등과금이 가능하고, 사용 내역의 상세한 정보를 요구하는 고객의 욕구를 충족시킬 수 있으며, 비과금 패킷 처리에 대한 과금요건을 수용하는 등 보다 유연하고 다양한 과금정책을 지원할 수 있다.이는 향후 이용자들의 요금에 대한 민원들이 줄게 되어 무선인터넷 서비스의 활성화에 크게 기여할 것이다.
