Zusammenfassung:	To provide a method, a device, and a system for reducing a waiting time during IRAT re-selection under the presence of a conflict state.SOLUTION: A method in a wireless communication system proceeds so that, until an IRAT re-selection procedure is completed, UE caches a message and/or other information related to a call setup procedure and completes the call setup procedure. The message is cached, for example, in a NAS layer or an RRC layer of a cellular modem or by an application processor.SELECTED DRAWING: Figure 9 【課題】競合状態の存在下でのＩＲＡＴ再選択中の待ち時間を低減する方法、装置及びシステムを提供する。【解決手段】無線通信システムにおける方法は、ＵＥが、ＩＲＡＴ再選択手順が完了するまで、コールセットアップ手順に関連するメッセージ及び／又は他の情報をキャッシュし、コールセットアップ手順を完了するように進む。メッセージは、例えば、セルラモデムのＮＡＳレイヤ又はＲＲＣレイヤにおいてか又はアプリケーションプロセッサによってキャッシュされる。【選択図】図９
