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

Mobile internet access

A method of authenticating a mobile wireless terminal in a mobile telecommunications network, the terminal being a subscriber of an Internet Service Provider (ISP) rather than of a mobile network. The terminal is allocated an International Mobile Identity (IMI) which is transmitted from the terminal to a mobile network when the terminal wishes to register with the network. A country code part and an operator ID part of the IMI are used by the network to determine the Internet Protocol (IP) address of the terminal's home ISP which is then contacted by the network over the Internet to authenticate the mobile terminal
