<p>A device and method for Mobile IP, wherein a mobility related binding cache is provided outside an individual correspondent node and managed on behalf of the correspondent node. Thus, the correspondent node may serve a mobile host without requiring additional functionality or configuration of correspondent nodes. This simplifies security policy management and allows to impart additional processing capacity for authenticating and authorizing the binding update requests to the thus proposed network entity instead of to the correspondent node separately.</p> |
