Patent ID: 10575360

Abstract:
The present disclosure relates to a communication technique of fusing a 5G communication system for supporting higher data transmission rate beyond a 4G system with an IoT technology and a system thereof. The present disclosure may be applied to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety related service, or the like) based on the 5G communication technology and the IoT related technology. More specifically, a method of the present disclosure for providing multi-connection of a terminal using different radio access technologies in a wireless communication system comprises the steps of: transmitting/receiving data through a first bearer corresponding to a first communication; transmitting/receiving data through a second bearer corresponding to a second communication; receiving, from a base station, a radio resource control (RRC) message which directs reestablishment of the first bearer as the second bearer or reestablishment of the second bearer as the first bearer; and reestablishing the first bearer or the second bearer on the basis of the RRC message.
