Method for controlling mobility of terminal, and device therefor

Abstract:

Provided are a method and device for controlling mobility, which reduce a delay or service interruption occurring in a handover process of a terminal. The method of a terminal may include receiving an RRC connection reconfiguration message including mobility control information from a master eNB; controlling data transmission to or data reception from a source secondary eNB to be maintained up to a specific point of time on the basis of the mobility control information; and transmitting a random access channel (RACH) for performing a random access procedure to a target secondary eNB.
