Abstract: Techniques are described for slice based public land mobile network selection. An example method includes a network node of a home public land mobile network (HPLMN) transmitting configuration information to a user equipment (UE) to configure the UE to receive enhanced slice-based steering of roaming (SoR) information during a registration process with a visited public land mobile network (VPLMN). The method further includes the network node determining that the UE is registering with the VPLMN. The method further includes the network node transmitting the enhanced slice-based SoR information to the UE based on the determination that the UE is registering with the VPLMN.

Abstract: Emergency services support is indicated to roaming devices in a wireless network. A user equipment (UE) may receive a message from the wireless network indicating at least one public land mobile network (PLMN) that provides emergency services support for devices in limited service. The UE may store, in a non-volatile memory (NVM), an identifier of the at least one PLMN in a whitelist of limited service emergency services support. In response to a trigger in a roaming limited service condition of the UE, the UE may establish an emergency session with a selected PLMN based on the whitelist of limited service emergency services support.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first authentication request in response to a first triggering request from the UE to a mobility management node of a first Tracking Area (TA) in which the UE is located. In some embodiments, the UE may prepare and store an authentication response according to the first authentication request. In response to determining that the UE has moved from the first TA to a second TA, the UE may abort a sending of the authentication response, and may send the stored authentication response according to the first authentication request to the mobility management node of the second TA in response to the receipt of the second authentication request and in further response to a determination that a given parameter of each of the first and second authentication requests are the same.

Abstract: A technique for determining that a wireless device supports using multiple subscriber identity module (SIM) cards to establish multiple connections to wireless networks, generating a multi-SIM capability message, transmitting the multi-SIM capability message to a first wireless network; and receiving a registration accept signal in response to the multi-SIM capability message, wherein the registration accept signal indicates a first set of features supported by the first wireless network. In another aspect, a technique for a wireless system to receive, via a network interface, a multiple subscriber identity module (multi-SIM) capability message from a wireless device connected to a first wireless network; generate a registration accept signal in response to receiving the multi-SIM capability message, wherein the registration accept signal indicates a first set of features supported by the first wireless network; and send, via the network interface, the registration accept signal to the wireless device.

Abstract: Apparatuses, systems, and methods for reducing wireless device service interruptions. An indication of a disaster condition may be provided to a wireless device. The disaster condition may affect a home public land mobile network of the wireless device. The wireless device may perform cell selection in a manner influenced by the indication of the disaster condition. This may include considering cells associated with a forbidden public land mobile network for the cell selection, or excluding cells associated with the home public land mobile network of the wireless device that are unavailable, for example due to the disaster condition, among various possibilities.

Abstract: Disclosed are embodiments for disabling N1 mode in response to several scenarios including an S-NSSAI failure, searching NR PLMNs after a loss of coverage in an attempt to maintain network slices, and triggering a UE to reattempt authentication of a rejected S-NSSAI when authentication credentials change and the UE either has N1 mode enabled or is camped on LTE PLMN that might be the same as the NR PLMN through which the S-NSSAI was rejected.

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.
