METHOD FOR SUPPORTING DATA FORWARDING DURING CONDITIONAL HANDOVER AND DUAL STACK PROTOCOL HANDOVER IN NEXT-GENERATION MOBILE COMMUNICATION SYSTEM

摘要

The present disclosure relates to a communication method and system for converging a 5^th-Generation (5G) communication system for supporting higher data rates beyond a 4^th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. According to the disclosure, it is possible to efficiently support data forwarding during conditional handover and dual stack protocol handover.
