METHOD BY WHICH TERMINAL FOR SUPPORTING MULTIPLE RADIO ACCESS TECHNOLOGIES RECOVERS WHEN RADIO LINK FAILURE HAS OCCURRED AND DEVICE FOR SAME

摘要

A method by which a terminal for supporting multiple radio access technologies (multi-RAT) recovers when a radio link failure has occurred can comprise the steps of: detecting a radio link failure of a first RAT while maintaining an RRC connection state with the first RAT; determining the radio link failure if a radio link of the first RAT does not recover after a predetermined first time elapses after the detection; and determining whether the radio link failure of the first RAT recovers during a predetermined second time after the determination.

1. A method of recovering a radio link by a use equipment (UE) for supporting multiple radio access technologies (RATs) (multi-RAT UE) when radio link failure occurs, the method comprising:
detecting a radio link failure of a first RAT while maintaining an RRC connection state with the first RAT; determining radio link failure when the radio link of the first RAT does not recover after a predetermined first time elapses after detection of the radio link failure; and determining whether the radio link failure of the first RAT recovers during a predetermined second time after the determining.
