This paper discusses current internet interconnection issues according to radical changes of internet traffic pattern. In this context, the recovery of network investment cost for network provider becomes hot issue. For recovery issues of investment cost, there are many disputes among stake holders. Therefore, it is necessary to investigate this issues in the context of internet interconnection. Also, it is important to develop the current regulation about internet interconnection under traffic changing environments. This paper selects four issues to deal with and analyzes the present situations and problems about these issues, and provides alternatives for internet interconnection corresponding to these four issues.

This study explores reasonable alternatives to internet interconnection policy. Due to the development of information and communication technology, patterns of the Internet usage are changing rapidly, including increase of video streaming services. For this reason, there is a lively discussion of the Internet interconnection policy, which integrates various Internet service operators into one ecosystem. We conducted an Analytic Hierarchy Process(AHP) analysis with 16 experts in government/public, and academic sectors, and alternative selection criteria and their corresponding alternatives and detailed tasks were evaluated. According to the results, the most important alternative selection criteria was a "fair charge against foreign service operators", and the most desirable alternative was "partial revise". Moreover, the experts responded that "reassessment of the principle of the charge" is the most urgent task to improve the Internet interconnection policy.

Internet is composed of many independent networks referred to as Internet Service Providers (ISPs) and each provider is generally interconnected based on a commercial agreement. Though many countries are engaged in deregulation in internet interconnection, there is still debate whether the large ISPs are unwilling to peer with small providers, have incentives to lower the quality of data transmission of transit operators or set the interconnection charge regarding the actual costs incurred by the interconnection. Korean government introduced regulations in internet interconnection after observing noticeable anti-competitive behaviors from 2005. This paper analyzes whether there is margin squeeze problem/market concentration, and suggests political proposals in Korean regulation status.

과거 독립적으로 운영되던 이동통신망과 유선인터넷망이 유무선 통합 서비스의 확대로 상호간의 트래픽이 교환되고 있고 기존의 유선 콘텐츠와 연계된 다양한 서비스들이 등장하고 있다. 현재 이동망과 유선망의 데이터망 간의 트래픽양이 많지 않지만 향후 망 개방 효과의 확대, 유무선 통합서비스 활성화, 통신서비스의 진화에 따라 트래픽 증가에 따른 처리에 대한 유선과 무선 사업자간 상호접속과 관련된 다양한 이슈가 발생할 것으로 예상된다. 본 논문에서는 이동통신망과 유선인터넷망 간의 데이터망 상호접속 현황 및 연동에 따른 수익구조 관계를 분석 한다. 또한 유무선 연동 구조의 가치체인과 관계 사업자를 분석하고 무선인테넷 요금제 유형에 따라 이동통신사, 유선계 사업자, 콘텐츠 사업자 중심으로 상이하게 나타나는 이해관계를 분석하고자 한다.

Internet and mobile traffic continues to surge exponentially in recent years due to popularization of smart devices, the appearance of various internet services carrying large amount of traffic from richer content and applications. This phenomenon leaded to various network problems such as the congestion delay, the non-balanced traffic ratio between ISPs, the continuous network investment cost and the Internet access problems. In light of changed data-driven communication ecosystem, There are growing concerns by both academia and industry that settlement-free peering and full transit regime have the limitations such as not only difficulties in maintaining mutual benefits but also difficulties in securing investment incentives for upgrading network performance and quality. Thus, it becomes more necessary for introducing the evolved internet interconnection regime which can fulfill the All-IP network environment. This study derives core issues regarding internet interconnection regime in Korea and suggest new evolved alternatives based on three point of view(traffic optimization, cost optimization, network investment optimization) through the empirical analysis.

Today the various types of communication and application service are provided by the development of Internet and IP technologies. It is expected to be extended the service domain of two networks through the interconnecting P2PSIP overlay which is highlighted as an important technologies for Internet based services and IMS(IP Multimedia Subsystem) which is the new architecture adopted in the evolution of NGN. Therefore, this paper explains the possible methods of the service expansion with interconnecting P2PSIP overlay and IMS network. Specially this paper suggests the interconnection architectures of P2PSIP overlay and IMS network as subscriber's types and analyzes the traffic analysis model and session set up delay characteristics by simulation model. As a results, this paper shows that the interconnection architecture using gateway AS(Application Server) is the excellent method to interconnect the IMS in case of P2PSIP overlay only subscriber, and that interconnection architecture using I-CSCF is good method to interconnect the IMS in case of P2PSIP overlay and IMS subscriber.

오늘날 인터넷기술의 급속한 발전으로 인하여 IP Phone서비스의 활성화가 기대되며 이러한 IP Phone 서비스시장의 확대는 기존 PSTN망에 의한 전화서비스시장에 지대한 영향을 미친다. 따라서 IP Phone 서비스시장에 있어서도 상호접속제도 도입의 필요성이 점증되고 있다. 이에 따라 본고에서는 IP Phone 서비스의 상호접속유형을 살펴보고 관련된 사업자간 정산문제에 대한 해결방안을 제시하고 있다.

초고속통신망에서 서비스 사업자 시스템에 적용될 번호체계, 상호접속 기준에 대한 기본적 요건과 기술적 표준 규정 등에 관한 연구가 미비한 실정이다. 초고속 서비스 사업자 망과 초고속 통신망에 접속 및 운용되는 시스템에서 초고속망의 번호계획을 위하여 연동을 고려할 대상 망은 기존의 전화망, 데이터망, ATM 망 및 ISDN 등이 있다. 본 고에서는 인터넷망과 ATM 망과의 연동시 발생할 번호체계의 상호접속 및 연동방안에 대하여 논한다. 현재 제정된 ITU-T 표준 규격을 중심으로 현존하는 망과 초고속 번호체계간의 상호 연동방안을 기술하였다. 또한 ATM 포럼 등의 사설기관에서 사용하고 있는 번호체계도 추가적으로 검토하였다.
