Accessing the Internet from a mobile computer can currently be done by opening a circuit switched call to the ISP (Internet service provider). New packet based services are now being introduced, such as the GPRS (General Packet Radio Service) for the GSM system. The solution described gives a simpler access to the Internet, at the same time providing complete user anonymity. However, the solution here does not exclude the use of traditional accounting methods, or more sophisticated electronic cash solutions which do not provide anonymity at the same level, as the solution described here. A MH (mobile host) attaching to a visited radio network receives an IPv6 address prefix from the access router in the visited network. The MH configures the whole IPv6 address for its interface. After initialization, it starts paying for the radio and Internet access to the visited radio operator. Paying method is e-cash, providing full anonymity for the mobile user. After receiving access to the network, the mobile user registers its current location information on a location server (dynamic DNS or some other), so that other hosts can resolve the mobile user's current IPv6 address and contact the roaming mobile user. The same e-cash, which is used to pay for the network access, will be used to buy services provided in the network. Services can be either local or global. Local service could be, for example, buying a soda, global such as receiving a video stream from a video server.
