Abstract
Facilitating node mobility includes facilitating a communication session for a mobile node communicated along a first communication path. A first anchor point manages context information for the communication session, where the context information comprises information for supporting the communication session. A command to transfer the context information to a second anchor point is received from a home agent. The second anchor point is operable to facilitate communication of the communication session along a second communication path. The context information is transferred in response to the command.
