Abstract
A method of authorizing an Internet Protocol (IP) enabled mobile host 1 to access the Internet 2 via an wireless LAN, GSM, UMTS access network 3 comprises initially sending an IP access request from the mobile host 1 to an IP router 5 within the access network 3. In response to receipt of said access request at the IP router 5, an IP address routing prefix is sent from the IP router 5 to the mobile host 1. Electronic cash is then forwarded from the mobile host 1 to a control point 6 within the access network 3. The control point 6 confirms the authenticity and/or sufficiency of the electronic cash and, providing that confirmation is made, sends an authorization message to the IP router 5. The IP router 5 blocks the transmission of IP packets between the mobile host 1 and the Internet 2 prior to receipt of the authorization message and permits the passage of IP packets only after an authorization message has been received.
