Title:
METHOD AND DEVICE FOR HANDOVER IN NEXT GENERATION MOBILE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/197307
Kind Code:
A1
Abstract:
Disclosed are: a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security, and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. In addition, the disclosure relates to a method performed by a source node in a wireless communication system, comprising the steps of: transmitting, to a target node, a handover request message including a conditional handover-related target cell identifier; receiving, from the target node, a handover request response message including a handover command message having configuration information about a target cell for a conditional handover; and transmitting, to a terminal, the handover command message and a radio resource control (RRC) reconfiguration message including condition information for the conditional handover.
