Abstract: Apparatuses, systems, and methods for SoR list management and PLMN selection based on an SoR list. A UE may receive an SoR container which may include a list of OPLMNs. The UE may store a prior list of OPLMNs stored on a USIM of the UE on a memory of the UE. The UE replace the prior list of OPLMNs stored on the USIM with the list of OPLMNs included in the SoR container. The UE may consider the prior list of OPLMNs as a lower priority list as compared to the list of OPLMNs stored on the USIM. Additionally, in response to determining to move from a current PLMN, the UE may scan for a new PLMN based on the list of OPLMNs stored on the USIM.

Abstract: A user equipment (UE) for handling slice information with single network slice selection assistance information (S-NSSAI) mapping for universal integrated circuit card (UICC) processor is provided. The UE operates by determining whether a baseband processor of the UE is in a busy state. Based on a determination that the baseband processor is not in the busy state, the baseband processor sends a fetch message to a UICC processor of the UE, where the fetch message is sent in response to receipt of a proactive-command-pending message from the UICC processor. The baseband processor receives a proactive-command message from the UICC processor, where the proactive-command message corresponds to a request for single network slice selection assistance information (S-NSSAI) information corresponding to one or more network slices. Finally, the baseband processor sends a response message with the S-NSSAI information to the UICC processor.

Abstract: A technique for establishing a voice call including receiving an indication that the first wireless system supports emergency service fallback, receiving an indication to establish an emergency voice call, transmitting an emergency service request to the first wireless system, determining that an unexpected error has occurred, selecting a second wireless system based on the determination that the unexpected error has occurred, and connecting to the second wireless system to complete the emergency voice call. Additionally, a technique for cancelling a voice call including receiving an indication that the first wireless system supports emergency service fallback, receiving an indication to establish an emergency voice call, transmitting an emergency service request to the first wireless system, receiving an indication to cancel the emergency voice call, and cancelling a connection to a second wireless system.
