Abstract
A method of enabling roaming of a mobile internet-access host (9) from a local area network (3) to a GSM network (6), each network having a home agent (HA) for routing internet datagrams between networks. The method comprises deregistering the mobile terminal (9) from said local area network (3) and registering it with the GSM network (6) and allocating to the mobile host (9) a new internet address in the GSM network (6). An internet security key is sent via the GSM Short Message Service from the local area network's home agent (HA) to the mobile terminal (9). The new internet address is transmitted, together with authentication data generated using the security key, via the internet (5) to the local area network's home agent (HA) which registers that address as a care-of-address for the mobile host (9).
Claims13
A method of communicating data between a mobile host and a remote station over the internet, where both the mobile host and the remote station are registered with the same or different cellular radio telephone networks, the method comprising the steps of:
- sending a security key, from the remote station to the mobile host, over the cellular radio telephone network(s) using a point-to-point packet switched service of the network(s);
- receiving said security key at the mobile host, and using the received key to secure subsequent data transmissions between the mobile host and the remote station over the internet.
A method of communicating data between a mobile host and a remote station over the internet, where both the mobile host and the remote station are registered with the same or different cellular radio telephone networks, the method comprising the steps of:
- sending a security key, from the remote station to the mobile host, over the cellular radio telephone network(s) using a point-to-point packet switched service of the network(s);
- and
- receiving said security key at the mobile host, and using the received key to secure subsequent data transmissions between the mobile host and the remote station over the internet;
- wherein the or each cellular radio telephone network is a GSM network and said point-to-point packet switched service is the Short Message Service (SMS).
Data communication apparatus comprising:
- a mobile host arranged for connection to the internet and to a cellular radio telephone network and having first signal processing means for encrypting and decrypting data sent to and received from the internet;
- a remote station arranged for connection to the internet and to a cellular radio telephone network, and having second signal processing means for encrypting and decrypting data sent to and received from the internet, the remote station further comprising means for providing a security key and for sending the security key to the mobile host over the cellular radio telephone network(s) using a point-to-point packet switched service of the network(s);
- the mobile host further comprising means for receiving said transmitted security key, wherein said security key may be used to secure subsequent data transmissions between the mobile host and the remote station over the internet.
A method of communicating data between a mobile host and a remote station over the internet, where both the mobile host and the remote station are registered with the same or different cellular radio telephone networks, the method comprising the steps of:
- sending a security key, from the remote station to the mobile host, over the cellular radio telephone network(s) using a point-to-point packet switched service of the network(s);
- receiving said security key at the mobile host, and using the received key to generate authentication data, the authentication data being sent to the remote station to secure subsequent data transmissions between the mobile host and the remote station over the internet.
