description The invention discloses a method for transferring service based on an Internet Protocol, and a service control unit. The method comprises the following steps: the service control unit receives a transferring message from seats when call subscribers and the seats are in conversation; the service control unit transfers the service according to the transferring message; before the service is successfully transferred, the service control unit notifies the seats to release resources. The invention solves the problems that the service is difficult to implement due to more interactive steps of SIP (Session Initiation Protocol) signaling and long reservation time of resources in the related technologies, reduces the interactive times of the media, and reduces the frequent application and release of the network resources.
