3GPP LTE/SAE 네트워크에서의 인증 시그널링 부하에 대한 평가

국문 초록 (Abstract)

통합된 코어 망 구조(core network architecture)와 다양한 무선 가입자 행동들은 3GPP in Release 8에서 제안된 EPC(Evolved Packet Core Network)에서 상당한 시그널링 부하 증가를 가져온다. 따라서 인증 시그널링 분석(authentication signaling analysis)은 체감품질(quality-of-experience)을 충족시키면서 인증 시그널링 부하와 지연을 줄이는 통찰력을 갖게 해준다. 본 논문에서는 갱신 과정 이론(renewal process theory)에 기반을 둔 분석적 모델링을 통해 EPS 구조에서의 시그널링 부하에 대해 평가하였다. 갱신 과정 이론은 특정 랜덤 과정(random process)에 상관없이 잘 작동 한다 (예. 포아송(Poisson)). 본 논문은 발신 발생 속도(call arrival rate), 이동성(mobility), 가입자들의 선호도와 운영정책의 관점에서 가입자들의 다양한 패턴을 고려하였다. 매개변수들과 성능지표들 사이의 상호관계를 나타내기 위해 수치적인 결과를 사용하였다. 수직적 핸드오버(vertical handover) 성능의 민감도와 heavy-tail process의 영향에 대해서도 검토하였다.

다국어 초록 (Multilingual Abstract)

The integrated core network architecture and various mobile subscriber behavior can result in a significant increase of signaling load inside the evolved packet core network proposed by 3GPP in Release 8. Consequently, an authentication signaling analysis can provide insights into reducing the authentication signaling loads and latency, satisfying the quality-of-experience. In this paper, we evaluate the signaling loads in the EPS architecture via analytical modeling based on the renewal process theory. The renewal process theory works well, irrespective of a specific random process (i.e. Poisson). This paper considers various subscribers patterns in terms of call arrival rate, mobility, subscriber"s preference and operational policy. Numerical results are illustrated to show the interactions between the parameters and the performance metrics. The sensitivity of vertical handover performance and the effects of heavy-tail process are also discussed.
