VERTICAL HANDOFF

摘要

Methods, Mobile Node and Mobility Access gateway for enabling vertical handoff of the Mobile Node between a first interface of the Mobile Node bearing an address A@ to which a prefix is associated and second interface of the Mobile Node used to connect towards the Mobility Access Gateway, the method comprising the steps of : - in the Mobility Access Gateway, generating a network pfB' in relation to the prefix pfA; - generating a Pad Translator (PaT) used to change between the address B@ and the address A@; and sending from the Mobility Access gateway the pfB' towards the Mobile Node over the Mobile Node's second interface.
