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.

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.

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.

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.

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.
