Abstract(in English) Recently, several types of mobile data networks, such as cellular phone based data network and wireless LAN based hot spot network, are available. Accordingly, it becomes common that one terminal has multiple subscriptions and switches over between those networks. In such an environment, it is required that multiple networks coordinate with each other, in such a way as continuing a communication even after switching from a low speed cellular network to a high speed hot spot network. Currently, many researches on this global roaming among networks focus only on the radio transmission level. However it is considered that multiple networks are operated independently in a network control level, and therefore a global roaming procedure considering the independence of network control scheme. In this paper, we discuss a global roaming procedure for independently operated Mobile IP networks. Our procedure exploits the co-located care of address in Mobile IP and realizes the global roaming without any modification Mobile IP network elements, such as home agents and foreign agents.
