Study on Trends in Standardization of Lawful Interception and the Continuous Packet Capture in Heterogeneous Networks

Abstract

Lawful interception(LI) is carried out in accordance with the relevant laws and regulations of each country‘s law enforcement authorities(LEA: Law Enforcement Agencies) and is refers to the act of receiving authorization (warrant) on the interception before performing the tapping of these legal acts. Lawful interception of the traditional public network PSTN (Public Switched Telephone Network), 2nd and 3rd generation of wireless networks was carred out by connecting directly to the switch like a conventional 접수일(2015년08월07일), 심사의뢰일(2015년08월18일), 심사완료일(1차:2015년09월02일) 게재확정일(2015년10월10일), 게재일(2015년10월31일) 701-866 대구광역시 동구 아양로 352, 사서함 304-304, 지휘통신과. email: lmr2010@korea.ac.kr 52851 경남 진주시 동진로 420, 국방기술품질원 정보화기획실. email: yshan08@gmail.com (교신저자) 04383 서울특별시 용산구 이태원로 22, 국방부 군수정보화팀. email: softkim@gmail.com 합법적 감청의 표준화 동향과 이기종 통신망에서의 연속적 패킷 수집에 관한 연구 Copyright c 2015 SERSC 428 cable network. However, the mobile phone (mobile phone) or Voice over IP (VoIP) technology those provide mobility need a new approach to ensure LI. It is necessary to perform a continuous LI in the wide range of network environments while guarantee the continuity of mobile node’s communication. In this paper, we analyzed the traditional lawful interception laws and concepts of the United States, Europe and international standardization trend of LI. In addition, we proposed continuous LI architecture to perform dynamic triggering in heterogeneous networks and verified its effectiveness by experiment.
