摘要： Provided are a seamless service method controlled by a user terminal, the method including: storing radio access technology (RAT) information and service flow information associated with a connecting radio access network (RAN); when a new link is detected, storing RAT information associated with the new link; verifying whether a new RAN satisfying a handover initiation criterion exists; when the new RAN exists, attempting a link connection with the new RAN; being assigned with an Internet Protocol (IP) to be used in the new RAN; setting up a handover service flow using the new RAN; and receiving a service via multiple paths using a connecting service flow and the handover service flow. Through this, it is possible to provide the seamless QoS even while the handover is being performed.
