Abstract: Apparatus and methods to support handover of emergency services sessions by network elements and by a wireless device between wireless networks are disclosed. The wireless device indicates an emergency services handover to applicable network elements, including an evolved Packet Data Gateway (ePDG), in one more messages when transferring an established emergency services session from a cellular wireless network to an untrusted non-cellular wireless network. In some embodiments, the wireless device includes a predefined string as part of a set of identification data in an IKE_AUTH request message sent to the ePDG. In some embodiments, the wireless device includes a previously allocated IP address within a payload of the IKE_AUTH request message to indicate handover of an existing session. By providing both the predefined “EMERGENCY” string and the previously allocated IP address, the wireless indicates a handover of an emergency services session between wireless networks.

Abstract: This Application describes mechanisms for enterprise remote management of cellular services provided via access credentials, e.g., subscriber identity modules (SIMs) and/or electronic SIMs (eSIMs), for wireless devices. To minimize requirements for user interaction, installation and management of business-supplied cellular service profiles on the wireless device can intercept alert notifications to reduce interruptions and allow for background management of the business-supplied cellular service profiles. Additionally, a business enterprise can use multiple, distinct services to initiate installation of an eSIM to a wireless device. When two different services attempt to install eSIMs on the wireless device in parallel, management software on the wireless device can control an order of installation and disallow duplicate installations of an identical eSIM to the wireless device. The management software can also monitor eSIM installations and manage alert notifications that occur during the eSIM installation process.

Abstract: Apparatus and methods to support emergency services sessions by network elements and by a wireless device are disclosed. The wireless device, when roaming to a visited country/region, queries a network-based server to obtain information for Public Land Mobile Networks (PLMNs) that support emergency services sessions via non-cellular wireless access in the visited country/region. The network-based server responds with a list of PLMNs from which the wireless device selects a PLMN. The wireless device further queries the network-based server to obtain information for evolved Packet Data Gateways (ePDGs) for a selected PLMN and receives from the network-based server a list of Internet Protocol (IP) addresses for ePDGs that support emergency services sessions via non-cellular wireless access for the selected PLMN. The wireless device further queries the network-based server for local numbers of the visited country for establishing emergency services sessions and receives a categorized list of local numbers for emergency services.

Abstract: A method performed by a station that includes receiving information from a cell of a Public Land Mobile Network (PLMN), determining whether the information indicates the cell supports circuit switched fallback (CSFB) voice calls, when the CSFB voice calls are not supported, determining whether at least one packet switched voice property of the station satisfies a predetermined condition and attaching to the cell of the PLMN when the predetermined condition is satisfied. A further method performed by a station connected to a PLMN that includes identifying cells of the PLMN available for the station to camp on, determining whether the station is capable of executing packet switched calls, when the station is not capable of executing packet switched calls, determining whether the identified cells have a neighbor cell that supports CSFB voice calls and prioritizing the cells that are identified as having neighbor cells that support CSFB voice calls.

Abstract: Apparatus and methods to support emergency services through untrusted wireless networks by a user equipment (UE) are disclosed. The UE detects a request for emergency services to be provided via an untrusted wireless network. The UE de-registers from any non-emergency services and releases any existing PDN connections. The UE sends a request for emergency services to an evolved packet data gateway (ePDG) at an Internet Protocol (IP) address obtained from a table or from a domain name system (DNS) server. The request includes an indication for emergency services using a configuration attribute assigned to indicate emergency services. The UE receives from the ePDG an indication of support for emergency services in a reply to the request.

Abstract: The described embodiments set forth techniques for transferring an electronic subscriber identity module (eSIM) with the same integrated circuit card identifier (ICCID) value from a source mobile wireless device to a target mobile wireless device directly with a mobile network operator (MNO) provisioning server. The target mobile wireless device downloads the eSIM from the MNO provisioning server after deletion of the eSIM on the source mobile wireless device and reassignment of the eSIM with the same ICCID value to the target mobile wireless device.

Abstract: Embodiments described herein relate to transfer of credentials between two mobile wireless devices that are within proximity of each other, via a secure local connection, or via a network-based cloud service, where the two mobile wireless devices are not in proximity to each other. Transfer of credentials can include communication between a source device, a target device, and/or one more network-based servers, which can include mobile network operator (MNO) managed servers, such as an entitlement server, a web-sheet server, an authentication server, a provisioning server, a subscription management data preparation (SM-DP+ ) server, a home subscriber server (HSS), and/or an authentication server, as well as third-party managed servers, such as a cloud service server and/or an identification services server. Authentication can be based at least in part on one or more tokens and/or a trust flag obtained by the source device and provided to the target device.

Abstract: A user equipment (UE) is configured to receive a system information block (SIB) from a base station, wherein a dedicated set of physical random access channel (PRACH) resources for redcap devices are explicitly configured in the SIB and transmit, in response to the SIB, an indication to the base station that the UE is a reduced capability (redcap) device.
