ABSTRACT:
The present invention provides a relocation of an application-specific functionality for an application that a mobile terminal (mobile node) is executing. Entities that may provide application-specific functionalities that assist the application include a location-based server (that may be associated with a supplementary service provider functionality), a transcoder proxy, and a security gateway. The relocation of the application-specific functionality with a network layer-level handoff enables the mobile terminal to seamlessly execute an application that utilizes the media content from a content source that is supporting the mobile terminal before the handoff Subsequent to the handoff, the mobile terminal registers with a current access router in order to inform the current access router about application context information. In the exemplary embodiments, the access routers and the content source support the discovery of an entity that can support the application-specific functionality and the configuration of the application-specific functionality after the handoff.
