Abstract: A user equipment (UE) that initiates a periodic update timer, wherein the UE is configured to perform a periodic registration update procedure in response to a periodic update timer expiry event, identifies that the periodic update timer has expired, wherein the periodic update timer expiry event occurs when the UE is out of coverage, selects a cell to camp on, wherein the cell is known to be in a non-allowed area and initiates the periodic registration update procedure in response to the periodic update timer expiry event, wherein the UE delays the periodic registration update procedure until the UE enters a fifth generation mobility management (5GMM) operating substate associated with camping on the cell that is known to be in the non-allowed area.

Abstract: A user equipment (UE) transmits a registration request message to a first public land mobile network (PLMN), wherein the first PLMN is a roaming PLMN, receives a registration accept message from the first PLMN, determines that the registration accept message includes a manipulated steering of roaming (SoR) container or does not include a SoR container, wherein the SoR container is configured by a home PLMN (HPLMN) of the UE and transmitted to the first PLMN from the HPLMN, determines that the registration accept message includes an indication that the first PLMN does not support voice over packet switching (VoPS) and adds the first PLMN to a first list of PLMNs in which voice service is not possible in an N1 mode.

Abstract: This application describes techniques for managing subscriber identity module (SIM) data for a wireless device, including secure storage and processing of SIM data. Select SIM data is encrypted using an encryption key by a processor external to a secure element, e.g., a universal integrated circuit card (UICC) or electronic UICC (eUICC), and at least a portion of the select SIM data is stored in the secure element. The select SIM data can be divided into multiple parts, where a first part of the encrypted SIM data is stored in the secure element, while a second part of the encrypted SIM data is stored external to the secure element, such as in a non-volatile memory (NVM) of the wireless device. The encryption key is stored in a secure NVM of the wireless device. The encrypted SIM data and the encryption key are required to decrypt and recover the SIM data.

Abstract: Disclosed herein are system, method, and computer program product embodiments for implementing prioritized return of a UE to NR RAT from a GSM/UMTS RAT through RAT reselection based approach. An embodiment operates by determining whether the UE is camped on a first radio access technology (RAT), and in response to a determination that the UE is camped on the first RAT, stores a list of frequencies and a plurality of cell reselection parameter values corresponding to the first RAT. The embodiment determines whether the UE is camped on a second RAT and whether one of a plurality of trigger conditions is satisfied, and in response to a determination that the UE is camped on the second RAT and that one of the plurality of trigger conditions is satisfied, performs measurements on one or more frequencies of the list of frequencies. The embodiment performs cell reselection to a cell of the first RAT based at least in part on the measurements and the plurality of cell reselection parameter values.

Abstract: If a paging or notification message is received by a user equipment (UE) when a UE-initiated 5GMM specific procedure or service request procedure is ongoing, a UE may buffer the paging or notification message. To buffer the paging or notification message, the UE may remember the pending mobile terminated transaction and re-attempt the registration or request procedure with the access category 0 (=MT_acc), if the ongoing UE-initiated 5GMM specific procedure or service request procedure fails due to access barring. If a 5GMM specific procedure or service request procedure is received by the network when a MT transaction is ongoing (i.e. a paging message with the access type set to 3GPP access or notification message via non-3GPP access with the access type indicating 3GPP access) the network may complete the incoming MT transaction and may remember the pending mobile terminated transaction and continue it once the MO transaction is completed.

Abstract: Systems and methods provide steering of roaming (SoR) information during a user equipment (UE) mobility registration process. In other systems and methods, instead of triggering mobility and periodic registration, a UE performs initial registration until a valid SoR is received in a visited country or network as long as a subscriber identification module (SIM) or a universal SIM (USIM) of the UE indicates that the UE is expected to receive SoR information due to initial registration in a visited public land mobile network (VPLMN).

Abstract: Some aspects of this disclosure relate to apparatuses and methods for the reselection of a Radio Access Technology (RAT) for a multi-mode user equipment (UE). A UE can determine that the UE camps on a first RAT for service by a first public land mobile network (PLMN) and that the UE camps on a second RAT for service by a second PLMN, and store information about the first RAT for the first PLMN. The UE can further determine whether there is a trigger event to enable the UE to switch from the second RAT to the first RAT. In response to a determination that there is the trigger event, the UE can determine whether a cell in the first RAT for the first PLMN is available for the UE to camp on to select the available cell in the first RAT to register the UE with the first PLMN.

Abstract: Methods and apparatuses are disclosed for requesting and providing service of a network slice deemed essential by a user equipment (UE). The UE transmits a request message to the network indicating that essential services are requested, and identifying the essential network slice. Based on the information in the request message, the serving network communicates with one or more network nodes to determine whether the requested services can be provided. This information is packaged in a response message and transmitted to the UE. If the current network is capable of servicing the requested network slice, then the UE remains with the current network. If not, then the UE initiates a search for an alternative network (PLMN or SNPN) capable of supporting the requested services. A successful search causes the UE to register with the newly-found network, whereas an unsuccessful search causes the UE to re-register with the current network.
