Abstract
This paper describes a mobility management framework for train passenger communications centred on an IP-based hybrid high altitude platform (HAP)-Satellite network. With their inherent wide area coverage, satellites have been used to provide mobile communications services and Internet access for global vehicular transportation systems. In analogy, HAP networks can provide wireless communication services complementary to those offered by satellite and terrestrial networks. In this paper, an integrated HAP-Satellite communication network architecture is proposed to support mobile Internet access for train passengers. To ensure service continuity and service quality throughout the train journey, mobility management and QoS support need to be carefully designed, Mobile IP is adopted to support macro-mobility and to to provide transparent handover operation to service connections and RSVP is used to provide QoS support to ensure the required service quality of multimedia applications running over the hybrid HAP-Satellite train network is still satisfied during handover. However, combining Mobile IP with RSVP poses several challenges due to the difference in their operation layers. In this paper, a handover algorithm that integrates Mobile IP and RSVP to simultaneously support mobility and QoS is derived. A signaling interface that can either loosely or tightly couple Mobile IP and RSVP is described. The associated signaling protocols are also presented in this paper.
