CONTEXT MANAGEMENT IN SESSION TRANSFER

摘要

A system with context detection and transfer prediction and early-preparation ability to reduce user waiting delay in a data communication network comprise of one source terminal UE who possesses the session that can send its device information to application server; one application server that can detect dynamic context of all devices related to the ongoing session and can predict possible transfer; one transfer target terminal UE that can cooperate with application server to accomplish early transfer preparation. These apparatus are connected through IMS platform, regardless of subscriptions. A method that device information is provided; application server monitors real time status of devices and predict potential media/session transfer based on context; application server indicates target device and/or remote party preparing for possible transfer; once preparation done, source device is asked whether to transfer the media or session. UE may also perform context detection and prediction, but eventually preparation is done through server. From this procedure, user will not see any delay when he agrees to transfer media or session to another device.
