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: 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: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for support recovering service in a radio access technology (RAT) for a multi-mode user equipment (UE). The UE can be registered to communicate in a first RAT, and the UE is in an idle mode, and the UE is in a disable mode with respect to communication in the second RAT. A cell selection for the second RAT can be performed. Afterwards, a registration procedure with a wireless communication system to communicate in the second RAT can be performed. Hence, the UE can receive wireless service from the wireless communication system through a base station associated with the second RAT.

Abstract: Techniques discussed herein facilitate configuration of network slices for a User Equipment (UE) supporting constraints on simultaneous operation of slices. One example embodiment is a UE device configured to: transmit a registration request message to request registration on a set of requested network slices; and receive a registration accept message indicating the UE is registered to a set of allowed network slices, and wherein the registration accept message indicates slice compatibility information for each allowed network slice of the set of allowed network slices for the UE, wherein the slice compatibility information for each allowed network slice indicates whether or not other configured network slices of the set of configured network slices are compatible with the configured network slice for simultaneous operation by the UE.

Abstract: A user equipment (UE) may perform a UE parameter update (UPU) procedure or a steering of roaming (SoR) procedure based on information received from a home public land mobile network (HPLMN). The UE receives, from a network component, an update container comprising updated parameters for the UE and a counter value associated with the update container, compares the counter value with a stored value and performs an action related to the update container based on at least the comparison of the counter value with the stored value.

Abstract: Systems and methods for managing synchronization of protocol data unit (PDU) sessions between a user equipment (UE) and a network are disclosed herein. In some embodiments, a determination of whether a message comprising a PDU session status information element (IE) should be sent is based on previous messaging between peer entities of the network. In some embodiments, a determination that the peer entity is informed of a relevant PDU session status is made after expected reply messaging is received in response to prior messaging. In some cases, a reply message without a PDU session status IE is sent from one entity to a peer entity when it is determined that each entity has a matching PDU session status. Cases involving failures detected at the network, and cases where an entity activates a data radio bearer (DRB) of a PDU session that is inactive at its peer are also discussed.

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.
