| 20150264738 | METHOD BY WHICH TERMINAL FOR SUPPORTING MULTIPLE RADIO ACCESS TECHNOLOGIES RECOVERS WHEN RADIO LINK FAILURE HAS OCCURRED AND DEVICE FOR SAME - 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. | 09-17-2015 |
