METHOD AND APPARATUS FOR LOGGING AND REPORTING RADIO LINK FAILURE INFORMATION IN NEXT-GENERATION MOBILE COMMUNICATION SYSTEM

摘要

The disclosure relates to a communication technique for combining an IoT technology with a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. The disclosure can be applied to intelligent services (e.g., smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, security and safety related services, etc.) based on 5G communication technologies and IoT-related technologies. The disclosure provides a method and an apparatus for logging and reporting information relating to a radio link failure. The method includes receiving, from a first base station that operates based on a first RAT, a UE information request including information indicating whether the terminal reports an RLF; and transmitting, to the first base station, a UE information response including an RLF report, in response to the information indicating a reporting of the terminal for the RLF.
