Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to perform to perform capability updates. Under at least some circumstances, the UE may use a non-cellular (e.g., non-3GPP) access to transmit updated capability information to a cellular network. Elements of the core of the cellular network may provide an identifier corresponding to the updated capability information to the UE for use in future registrations with the cellular network. Further, the core network may provide the updated capability information to a cellular radio access network associated the cellular network. The UE and the cellular network may communicate according to the updated capability.

Radio capability update procedure over non-3GPP access

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.

5G NR voice call EPS fallback enhancements

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.

Enhancements for radio access capability signaling (RACS)

Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for enhancement of multi-SIM devices, such as UE. A network may increase paging retries for known MU-SIM devices, e.g., based on an indication of capabilities from a MU-SIM device. The indication may be via a NAS registration request, an RRC capability procedure, and/or an RRC UE assistance procedure. Additionally, a network may include an indication of a paging priority to the UE. The UE may then determine a response to the page based, at least in part, on the indicated priority. Further, the UE may indicate a tune-away to the network. The indication of the tune-away may include a cause and/or duration for the tune-away and may be provided at an RRC level or a network access stratum (NAS) level.

System enablers for multi-SIM devices

Apparatuses, systems, and methods for a wireless device to perform methods to dual-registration in a fifth generation (5G) New Radio (NR) network, including notification procedure enhancements over cellular (e.g., 3GPP) and non-cellular (e.g., non-3GPP) access, dual-registration enhancements, and paging enhancements. Methods also include procedures for a network to determine an access type to notify a UE of pending data and for a wireless device and network to mitigate paging collisions.

5G new radio NAS notification procedures

A mobile device (UE) may access standalone non-public networks (SNPNs) in various different locations as equivalent SNPNs (eSNPNs) corresponding to a home SNPN of the device. The device may obtain a list of eSNPNs corresponding to the home SNPN, and may access a second SNPN at a location different from a location of the home SNPN, in response to identifying the second SNPN and the list including the second SNPN as an eSNPN corresponding to the home SNPN of the device. The eSNPNs may include roaming eSNPNs (ReSNPNs) for accessing an enterprise NPN globally and/or at various different locations. The eSNPN/ReSNPN list may be maintained in a new network identifier management function (NMF). NPNs may be implemented as network slice instances (NSIs) via identifying data in the single network slice selection assistance information (S-NSSAI). Multiple credentialed SNPNs of a UE may be prioritized for access by the UE.

Non-public wireless communication networks

A user equipment (UE) is configured with operations to determine whether a network supports non-voice IP Multimedia Subsystem (IMS) services. The UE determines whether a network with which the UE is communicating supports a non-voice IP Multimedia Subsystem (IMS) service and when the network supports the non-voice IMS service, initiates an IMS Protocol Data Unit (PDU) session establishment with the network.

IMS support for non-voice services

A user equipment (UE) may be configured to reattempt to establish a multiple access (MA) protocol data unit (PDU) session when the UE moves to a new registration area. The UE transmits a request for a MA PDU session to the network, receives a message from the network indicating the request has been rejected, wherein the message further includes a status indication for reattempt requests to establish the MA PDU session, determines, when the UE moves into a new registration area of a PLMN, whether reattempt requests are allowed based on, at least, the status indication and transmits, when reattempt requests are allowed, a further request to establish the MA PDU session.

Establishing a multiple access connection

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.

WLAN to cellular handover techniques for voice calls

Embodiments are presented herein of apparatuses, processors, systems, and methods for performing Quality of Service handling procedures. A wireless device may establish a cellular link that provides access to a fifth generation core network. The wireless device may establish a protocol data unit session with a cellular network entity of the fifth generation core network. The wireless device may determine one or more Quality of Service flow descriptions for the protocol data unit session. The wireless device may perform one or more Quality of Service related modifications to the protocol data unit session.

Quality of service handling procedures

Apparatus and methods to support parallel access to services of multiple subscriber identity modules (SIMs) and/or electronic SIMs (eSIMs) by a wireless device are disclosed. The wireless device is a single-radio wireless device that includes wireless circuitry that supports an active voice or video connection via a single radio access network of a cellular wireless network at a time. To send or receive data for a second SIM/eSIM, when an active voice or video connection for a first SIM/eSIM uses the wireless circuitry, the single-radio wireless device can i) establish parallel, linked protocol data unit (PDU) sessions for different SIMs, ii) multiplex traffic for different SIMs over a common radio connection with SIM information embedded in protocol headers for routing by network equipment, and/or iii) use an additional dedicated bearer using a first, active SIM for each data network name (DNN) over which to route for a second, suspended SIM.

Methods and apparatus to support access to services for multiple subscriber identity modules

System enablers for multi-sim devices

Manners of controlling a data rate for a user equipment (UE) on a per slice basis by either a core network or a radio access network (RAN). In one exemplary manner, a request is received to establish a new Protocol Data Unit (PDU) session for a network slice for a user equipment (UE), a maximum session throughput value is received for the new PDU session, the maximum session throughput value for the new PDU session is added to an accumulated maximum session throughput value to determine an updated accumulated maximum session throughput value, the updated accumulated maximum session throughput value is compared to a maximum slice throughput value and, when the updated accumulated maximum session throughput value exceeds the maximum slice throughput value, an action is performed related to the new PDU session.
