Relocation of content sources during IP-level handoffs

摘要

The present invention provides a relocation of content sources that provide media content to a mobile terminal (mobile node) when a network layer-level handoff occurs. The relocation of content sources enables the mobile terminal to seamlessly execute an application that utilizes the media content from a current content source before the handoff and from a new content source after the handoff. The mobile terminal registers with a current access router in order to inform the access router about application context information. The current access router informs a new access router about the impending handoff. The new access router consequently discovers the new content source.
