Abstract
Service provisioning in mobile terminals is provided through registering and transferring of application context, which permits substantially seamless transfer of application functionality across administrative service domains. An architecture for providing application context transfer may include access routers, transcoder proxy servers, and gateway routers. A mobile terminal served by a current access router creates an application context for a session and registers it with the current access router. Around the time of handoff, the current access router transfers the application context to a new access router associated with a new administrative domain and a new access network. The new access router evaluates the application context and takes steps to provide application functionality for the mobile terminal and current sessions. These steps may include the use of a network entity, such as a transcoder proxy server, to modify data for a session and thereby provide application functionality in the new administrative domain.
