Abstract: A terminal executes a random access procedure with a target base station depending on a pre-random access channel (pre-RACH) command in a handover preparation step executed between a source base station currently accessed by the terminal and the target base station when the terminal receives the pre-RACH command from the source base station through layer2 (L2) signaling in the handover preparation step.

Abstract: Disclosed herein are a method and an apparatus for a buffer status report in a mobile communication system. The method for a buffer status report includes setting a new QoS class identifier (QCI) value for supporting a radio bearer (RB) added for a low latency service; and allocating a logical channel of a RB for an existing service and a logical channel of a RB for the low latency service to logical channel groups (LCGs) in consideration of the newly set QCI value. Further the buffer status report for each logical channel performed in an LCG unit is received.
