1. An apparatus comprising:
- a mobile terminal communications interface; and
a processor configured to communicate through the communications interface, the processor configured to perform;
initiating an application supported by the apparatusreceiving, from a current content source, a packet data stream that is associated with the application;
forwarding application context information that is associated with the application to an access router for registration thereon, the application context information including a content profile and a media description, the application context information configured to be used in establishing a connection with a new content source; and
receiving the packet data stream from the new content source in response to the apparatus completing a network layer-level handoff.

Abstract
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.
