Abstract

In this paper, we propose a novel applying method of Mobile IPv6 service into the UMTS to solve the mapping problems in the GGSN TFT packet filter. The mobility management tables or the GGSN should be maintained as the same as the MN and the CN. Our proposed scheme copes with the problem when the RO procedure is not normally performed by using Mobile IPv6 signaling packets in the GGSN and adding a function block in the UMTS. To show the performance of our proposed algorithm, we accomplish the simulations of measuring the delay time in the cases of success and failure of the RO procedure. Also, the amount of transmission is observed when the packet transmission is assured in the case of the successful RO procedure.

본 논문에서는 UMTS에 Mobile IPv6를 적용할 경우에 GGSN의 TFT packet filter에서 발생하는 문제점을 해결하기 위한 알고리즘을 제안하였다. 제안된 알고리즘에서는 GGSN이 Mobility option을 가지는 Mobile IPv6 시그널링 패킷을 사용, MN과 CN이 가지는 고유한 테이블을 유지하여 RO이 정상적으로 수행되지 않는 문제점을 해결하였다. 제안하는 알고리즘의 타당성을 위하여 RO이 정상적으로 수행될 경우와 그렇지 않을 경우에 지연시간 측정과 RO을 사용하더라도 패킷 전송보장이 될 경우와 그렇지 않을 경우에 대한 패킷 전송량을 측정하여 실험에 관한 시뮬레이션을 수행하였다.
