Title:
METHOD AND APPARATUS FOR HANDLING EN-DC CELL RESELECTION INDICATOR IN NEXT-GENERATION MOBILE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/187926
Kind Code:
A1
Abstract:
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-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. A method performed by a terminal is provided. The method includes receiving, from a base station, a message for releasing a radio resource control (RRC) connection, the message including information indicating to apply alternative cell reselection priority information for a cell reselection, receiving, from a cell of the base station, system information associated with the cell reselection, in case that the system information includes cell reselection priority information and the alternative cell reselection priority information, performing the cell reselection for evolved-universal terrestrial radio access (E-UTRA) frequency and inter-radio access technology (RAT) frequency by applying the alternative cell reselection priority information to the E-UTRA frequency, and in case that inter-RAT cell is selected, deleting the information indicating to apply the alternative cell reselection priority information.
