Abstract

This paper describes how a heterogeneous network that comprises of satellite and WLAN systems could be implemented in a high-speed train environment to provide Internet access. The focus of the paper is on the design of the network architecture and mobility management procedures. In particular, the implementation of WLAN to complement satellite coverage in various operating environments is investigated. For mobility management, issues related to location and handover management are described. In addition, the paper also elaborates on the use of location detection procedures and antenna diversity in trains to aid the process of handover.
