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: This disclosure describes a communication system associated with a radio access technology (RAT). The communication system includes an Internet protocol (IP) multimedia subsystem (IMS) server, and one or more processors configured to perform operations. The operations include receiving, from a user equipment device (UE) camped on the RAT, a request for IMS Packet Data Unit (PDU) establishment or IMS session initiation protocol (SIP) registration; sending to the UE a rejection message associated with the SIP registration or the IMS PDU establishment; receiving, from the UE, an IMS failure message that comprises an IMS failure cause; determining, based on the IMS failure message, whether the IMS failure cause is temporary or permanent; and responsive to determining that the IMS failure is temporary, temporarily disabling the RAT for the UE.

Abstract: Apparatuses and computer-readable storage media for handling timers for mobile terminated circuit-switched fallback (MT CSFB) calls. An apparatus for a user equipment (UE) includes processing circuitry operably coupled to a data storage device. The data storage device is configured to store a value of an extended service request for mobile terminated services (EXT-MT) timer. The value of the EXT-MT timer is less than a value of a guard timer of a Visitor Location Register (VLR). The processing circuitry is configured to start the EXT-MT timer and generate an extended service request message to be transmitted to a Mobility Management Entity (MME) responsive to a paging for an MT CSFB call, and attempt to select a radio access technology of a different type of network if the EXT-MT timer expires before the UE successfully performs inter system change and a circuit switched fallback cancellation request was not received from a subscriber.

Abstract: Methods and apparatuses for dynamically enabling and disabling one or more of a multimedia priority service (MPS) and a mission critical service (MCS) are disclosed. In some embodiments, a user equipment device (UE) comprises: at least one antenna; at least one radio coupled to at least one antenna, wherein at least one radio is configured to perform cellular communication; and one or more processors coupled to the at least one radio, wherein the one or more processors and at least one radio are configured to dynamically enable and disable use of a service from a group of services that includes a MPS and MCS.

Abstract: This disclosure describes a user equipment device (UE). The UE includes one or more antennas; one or more radios, where each of the radios is configured to perform cellular communication using a plurality of radio access technologies (RATs) that support voice over an Internet protocol (IP) multimedia subsystem (IMS); one or more processors coupled to the one or more radios, where the one or more processors are configured to cause the UE to perform operations including: sending, via a first RAT, a first request for IMS registration to an IMS server; receiving, from the IMS server, an IMS rejection message indicating failure of the IMS registration; determining, based on the IMS rejection message, that the IMS registration failure is temporary; responsively re-attempting IMS registration with the IMS server; and determining to camp on the first RAT in response to receiving an IMS acceptance message from the IMS server.

Abstract: User equipment devices (UEs) and methods are described for performing single network slice selection assistance information (S-NSSAI)-aware public land mobile network (PLMN) selection in a roaming scenario. A mapping list is received that includes a mapping of a plurality of public land mobile networks (PLMNs) to corresponding S-NSSAI values. The mapping list is received from a home PLMN (HPLMN) of the UE over non-3rd generation partnership (non-3GPP) access, from a server, or from a Universal Mobile Telecommunications Service (UMTS) subscriber identity module (USIM) of the UE. An available PLMN is determined that is mapped to a preferred S-NSSAI value of the UE based on the mapping list. A connection is established with the available PLMN.

Abstract: A wireless device may transmit, using a first SIM associated with a first radio, a first attach request to a network node and transmit, using a second SIM associated with a second radio, a second attach request to the network node. Additionally, the wireless device may receive, operating in a multiple-subscriber identity module (MSIM) mode, an attach reject message including an attach reject cause code from the network node. The wireless device may transition, based at least in part on reception of the attach reject message, the second SIM to a limited service camped state, disable one of the first radio or second radio, transition to a single-SIM mode, and communicate with the network node via the first SIM.
