Abstract:
Provided are a User Interface (UI)/User eXperience (UX) display method during timer T adjustment due to disaster roaming occurrence, and an apparatus for supporting same. A user equipment (UE) displays first information notifying that a disaster condition is applied for a home public land mobile network (HPLMN) and second information notifying that a specific PLMN has been selected from among at least one PLMN excluding the HPLMN. When the specific PLMN is a disaster roaming PLMN and the UE performs registration in the disaster roaming PLMN, a timer for periodically searching for the HPLMN does not operate, and the HPLMN is not searched for while the timer does not operate. The UE displays third information notifying that an attempt to access the HPLMN is stopped while the timer does not operate. Also, when the disaster condition is no longer applied for the HPLMN and/or the UE deviates from a disaster region, the UE displays fourth information notifying same.
