Title:
MOBILE COMMUNICATION METHOD AND RELAY NODE
Document Type and Number:
WIPO Patent Application WO/2012/008382
Kind Code:
A1
Abstract:
A mobile communication method of the present invention comprises: a step in which when a relay node (RN), which is in charge of a radio base station (DeNB) and in an "RRC_Connected state", detects an RLF, the relay node (RN) transmits an "RRC Connection Release" to a mobile station (UE) that is in charge of the relay node (RN) and is in an "RRC_Connected state"; a step in which the mobile station (UE) transitions to an "RRC_Idle state" in response to the "RRC Connection Release"; and a step in which the relay node (RN) transitions to an "RRC_Idle state" after a lapse of a given time from the transmission of the "RRC Connection Release".
