Messages exchanged between a mobile node and a home agent according to a mobile Internet protocol are authenticated using cryptographic methods applied to the messages and which have been agreed on between the mobile node and the home agent.

Method for verifying the authenticity of messages exchanged according to a mobile internet protocol

A user terminal is switched between a cellular network and a worldwide interoperability for microwave access radio network within a telecommunication system. An authentication, authorization and accounting (AAA) server which is designed for use with both of these networks is disposed in the telecommunication system in such a way that user data of the user terminal stored in the AAA server can be accessed from both of these networks, thereby advantageously ensuring uninterrupted switching between the two networks free of loss.
