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.

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: A device providing inter-device call continuity facilitated by a wireless audio output device may include a processor configured to initiate, over a peer-to-peer connection with a second device, a communication session between the second device and a third device. The processor may be further configured to establish, over the peer-to-peer connection with the second device, an audio link corresponding to the communication session. The processor may be further configured to determine, based at least in part on the audio link, that a connection quality of the peer-to-peer connection satisfies a connection degradation condition. The processor may be further configured to request, over a wide area network connection, for the communication session with the third device to be handed-off from the second device to the first device, and to establish, over the wide area network connection, the communication session with the third device.

Abstract: Apparatuses, systems, and methods for enhancement of network slicing for a UE. A UE may receive, from an AMF of a network, application related information associated with network slice data routing for data associated with an application. The information may be provided to the network by network slice customers. The UE may, in response to application initiation, determine traffic routing for data associated with the application. Traffic routing may be based on the application related information and a UE configuration associated with user privacy (e.g., user privacy setting) associated with the application. When the user UE configuration is enabled, the data may be routed via a default network slice and when the UE configuration is disabled, the data may be routed via a network slice indicated by the application related information. The UE configuration may be indicated by the application via a Boolean flag and/or via a user interface setting.

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: 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: Systems and methods performed by user equipment (UE) for communicating over a wireless communication network include receiving data representing one or more communication quality metrics for communication on a New Radio (NR) communication link of the wireless communication network. The method includes determining, based on the data representing the one or more communication quality metrics, a data throughput for the NR communication link of the wireless communication network. The method includes estimating a theoretical throughput for using a Long Term Evolution (LTE) communications link of the wireless network. The method includes comparing the data throughput using the NR communication link to the theoretical throughput for using the LTE communication link. The method includes causing a switch, based on the comparison, from the NR communication link to the LTE communication link.
