摘要：Next generation wireless/mobile networks will be IP
based cellular networks integrating the internet with cellular networks.
In this paper, we propose a new architecture for a high speed transport
system and a mobile management protocol for mobile internet users in
a transport system. Existing mobility management protocols (MIPv6,
HMIPv6) do not consider real world fast moving wireless hosts (e.g.
passengers in a train). For this reason, we define a virtual organization
(VO) and proposed the VO architecture for the transport system. We
also classify mobility as VO mobility (intra VO) and macro mobility
(inter VO). Handoffs in VO are locally managed and transparent to the
CH while macro mobility is managed with Mobile IPv6. And, from the
features of the transport system, such as fixed route and steady speed,
we deduce the movement route and the handoff disruption time of
each handoff. To reduce packet loss during handoff disruption time,
we propose pre-registration scheme using pre-registration. Moreover,
the proposed protocol can eliminate unnecessary binding updates
resulting from sequence movement at high speed. The performance
evaluations demonstrate our proposed protocol has a good
performance at transport system environment. Our proposed protocol
can be applied to the usage of wireless internet on the train, subway,
and high speed train.
