Abstract  Abstract

The present disclosure relates to communication methods and systems for converging 5 th generation (5G) communication systems for supporting high data rates beyond fourth generation (4G) systems with technologies for internet of things (IoT). The present disclosure may be applied to smart services based on 5G communication technologies and IoT-related technologies, such as smart homes, smart buildings, smart cities, smart cars, interconnected cars, healthcare, digital education, smart retail, security and security services. A method of a terminal in a communication system is disclosed, comprising: receiving a Radio Resource Control (RRC) message including information associated with a change from a first Packet Data Convergence Protocol (PDCP) entity for a bearer to a second PDCP entity for the bearer, identifying first data to be transferred from the first PDCP entity to the second PDCP entity among second data stored in the first PDCP entity, transferring the first data to the second PDCP entity, discarding the second data stored in the first PDCP entity and releasing the first PDCP entity, and processing the transferred first data in the second PDCP entity.
