Abstract: Apparatus and methods to support access to services of multiple wireless networks by a single-radio, multiple subscriber identity module (SIM)/electronic SIM (eSIM) wireless device are disclosed. To send or receive voice communications for multiple SIMs/eSIMs, when an active voice connection for a first SIM/eSIM uses wireless circuitry to connect to a first cellular wireless network via a first radio access network, the single-radio, multi-SIM/eSIM wireless device uses alternative data transports, such as via a wireless local area network (WLAN) or by tunneling through the first radio access network of the first cellular wireless network to connect to services of additional cellular wireless networks associated with the multiple SIMs/eSIMs.

Abstract: Apparatuses, systems, and methods for high data mode operation in cellular networks. A UE may determine, for an interface to a high-speed cellular network, a categorization from a plurality of categorizations, determine availability of the high-speed cellular network, and select, based at least in part on the categorization and availability of the high-speed cellular network, the interface for a data connection to the high-speed cellular network. The categorization may be one of expensive or not expensive and/or one of a first level associated with a higher compression codec rate or a second level associated with a lower compression codec rate. The UE may receive, from one of the a low-speed cellular network or the high-speed cellular network, carrier plan information for a cellular data service carrier and analyze the carrier plan information to determine desirability of a switch, e.g., from the low-speed cellular network to the high-speed cellular network.

Abstract: This disclosure relates to techniques for performing Wi-Fi authentication in a wireless communication system. Public key cryptography may be used to enhance the confidentiality of the user's permanent identity in transit. In some embodiments, a RSA-OAEP (SHA-256) encryption scheme may be used to protect the permanent identity when the EAP client needs to send the user's permanent identity to the server in the absence of pseudonym or fast re-authentication identity. In some embodiments, a server certificate is used to authenticate a iWLAN tunnel to protect an IMSI during setup of a Wi-Fi call. Using the methods described herein on both or either of the EAP client and server side may offer improved privacy protection.

Abstract: Methods and systems are disclosed for performing seamless voice call handover and data handoff between a cellular network and a non-cellular (e.g., Wi-Fi) network, by a link budget limited user equipment device (UE) in standalone mode. The cellular radio may be maintained in a non-communication mode when not in use, to prevent power and peak power issues that may be unique to link budget limited devices. In response to poor non-cellular performance in support of a voice call, the UE may transition the cellular radio from the non-communication state to an online state. If the cellular network indicates that packet-switched calls are supported, then the UE may initiate handover of the voice call to the cellular network. Various methods for seamless handoff of data communications are also disclosed, in both the presence and the absence of a voice call. Various metrics are disclosed to enhance handoff determinations.

Abstract: This disclosure relates to dynamic baseband management for a wireless device. The wireless device may be an accessory device. The accessory device may determine whether it has a short-range wireless communication link with a companion device. The accessory device may determine one or more proximity metrics relating to the companion device. The accessory device may further determine one or more metrics associated with user settings, user activity and/or application activity at the wireless device. The wireless device may select a (e.g., full, limited, or off) baseband operating mode based on any or all of these considerations.

Abstract: Apparatuses, systems, and methods for application aware cellular radio activation/deactivation, e.g., in 5G NR systems and beyond. The UE may receive, while operating in a power savings mode in which a cellular modem of the UE is disabled, inputs associated with an application of the UE. The UE may determine, based on the inputs, to activate the cellular modem to support the application of the UE. The inputs may include an indication of an application state or status, an indication of an application category, an indication of a state or status of an AI assistant of the UE, an indication of whether an application is a session application, an indication of network assertions, an indication of proximity information, an indication of a WiFi state or a WiFi status, and/or indications associated with one or more timers.

Abstract: A communications network may be used to convey Short Message Service (SMS) messages using the Internet Protocol (IP). User equipment may transmit an SMS-over-IP Session Initiation Protocol (SIP) message to wireless equipment over a high-bandwidth communications link. The wireless equipment may route the SMS-over-IP SIP message to the ePDG. When the high-bandwidth link is unavailable, the user equipment may transmit a compressed message to the proxy server over a low-bandwidth communications link. The proxy server may convert the compressed message into an SMS-over-IP SIP message that is transmitted to the ePDG. The proxy server may serve as a proxy for the first user equipment from the perspective of the ePDG. This may allow SMS message data to continue to be conveyed through the communications network even when the high-bandwidth communications link becomes unavailable.
