Abstract
In mobile IP networks, when a mobile node (MN) moves from one cell to another, handover occurs. The result of the handover is that the MN connects to the network through a new access router (AR). The handover may occur between access routers of the same or different administrative domains. In all cases, the information related to the mobile node has to be transferred from the old AR to the new AR in order to minimize the effect of the change of access routers.
Claims13
A method comprising:
- receiving a first rest of context from a first access router, said first rest of context having a static context and a second rest of context;
- extracting the static context from the first rest of context;
- forwarding a second rest of context to at least one network element;
- and
- sending a context transfer complete message to a second access router.
2 more elements
An apparatus comprising:
- a receiver configured to receive a first rest of context from a first access router, said rest of context having a static context and a second rest of context;
- an extractor configured to extract the static context from the first rest of context;
- a forwarder configured to forward a second rest of context to at least one network element;
- and
- a transmitter configured to send a context transfer complete message to a second access router.
