1. A method of performing a handover procedure, by a target base station, in a wireless communication system, the method comprising:
- receiving, from a source base station, a handover request message including a radio resource control (RRC) connection request message, wherein the RRC connection request message includes a specific establishment cause of a user equipment (UE), a UE-Identity field indicating a UE identity facilitating contention resolution, and a Random Value field indicating an integer value, wherein the specific establishment cause among a plurality of establishment causes includes emergency, high priority access, mobile terminated access, mobile oriented signaling, mobile oriented data, and delay tolerant access; and
transmitting, to the UE, a handover command message.
