Abstract: Apparatuses, systems, and methods for a network to notify user equipment device (UE) whether a network slice the UE has requested is subject to a quota. An AMF of the network may inform the UE if an allowed slice(s) is subject to quota management as part of a registration procedure via a registration accept and/or a UE configuration update command. In addition to providing information regarding whether an S-NSSAI is subject to quota management, the AMF may also share the percent of quota availability to the UE. The UE may implement access control logic based on the received available quota for a particular network slice.

Abstract: Apparatuses, systems, and methods for performing network slice quota management. A network slice quota management function may store capacity information for one or more network slices. The network slice quota management function may receive a request for an indication of whether a network slice has additional capacity. The network slice quota management function may provide an indication of whether the network slice has additional capacity in response to the request. The capacity information may relate to the capacity of the network slice with respect to the number of wireless devices registered for the network slice, or to the capacity of the network slice with respect to the number of packet sessions established with the network slice, or both, among various possibilities.

Abstract: Techniques are disclosed relating to handover of WLAN voice calls to one or more cellular networks. In some embodiments, a device is configured to perform voice communications over one or more wireless local area networks, communicate with a first network using a first cellular radio access technology (RAT), and communicate with a second network using a second cellular RAT. The device may store, based on communications via the first network, information indicating that the first network does not support voice communications for the apparatus. The device may handover a voice call from a wireless local network directly to the second cellular RAT, based on the stored information and without handover of the voice call to the first cellular RAT, based on call conditions on the wireless local area network.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE), manufacturer server, and/or cellular network to perform radio capability signaling. A new type of UE radio capability identifier is provided which may allow a network to distinguish between similar UEs that have or have not implemented a capability update. In order to perform a forced capability update, a manufacturer may issue information about the update to a cellular network (and receive acknowledgement of the information) prior to pushing the update to UEs. In response to an unforced capability update, a cellular network may maintain multiple UE radio capability identifiers for similar UEs which have or have not implemented the update. A UE radio capability identifier may be adjusted dynamically in response to temporary changes in the UE's capability.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for EPS fallback when initiating a voice call while camped on a 5G cell. The UE may camp on a 5G network by performing an IMS registration procedure/IMS SIP invite procedure with an IMS. The UE may initiate a voice call and determine that the voice call cannot be established over the 5G NR network. In response, the UE may perform a TAU procedure or an attachment procedure with a cell of a 4G network. The IMS may be transferred to the 4G network during TAU/attachment procedure. The UE may, in response to determining that it is barred from the 4G network, transition back to the 5G network and transmit, to the 5G NR network, a SIP cancel request to allow a context associated with the UE to be cleared from the IMS.

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: This disclosure relates to transmitting an emergency message to a user equipment device (UE) over a wireless local area network (WLAN). The UE may establish a connection with an access point through WLAN. The UE may transmit, via the access point and to a network entity, an indication that the UE supports receiving emergency messaging through the WLAN. At least in part in response to communicating the indication, the UE may receive, from the network entity and via the access point, an emergency message and location information. The UE may compare the location information with a location of the UE to determine whether the UE is located within a first region specified by the location information. Based on a determination that the location of the UE is within the first region, the UE may display the emergency message on a display of the UE.

Abstract: This disclosure relates to techniques for network delaying cellular re-registration during critical conditions. A wireless device may register for cellular service with a cellular network. The wireless device may receive a configuration update command from a network element of the cellular network. The configuration update command may request re-registration of the wireless device. The wireless device may determine to delay responding to the configuration update command based at least in part on one or more conditions in effect at the wireless device. For example, one possible such condition may include if a protocol data unit session associated with emergency services is active at the wireless device.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for de-registration of the wireless device from a first access type over a second access type. Methods also include procedures for maintaining state machines associated with both access types as well as procedures to determine a connection for re-transmitting a de-registration request and to avoid collisions between procedures associated with the first and second access types. Further, methods include an information element configured to indicate which access type has been de-registered.
