This application sets forth techniques for dynamically managing a shared provisioning electronic subscriber identity module (eSIM) for a wireless device. A shared (non-unique) provisioning eSIM is installed in the wireless device to provide limited functionality connectivity to services, such as for device activation and user eSIM provisioning. The shared provisioning eSIM includes records of IMSI values organized into groups of IMSI pools and priorities for selecting IMSI values for configuring the shared provisioning eSIM. An on-device shared provisioning SIM/eSIM controller resident on a cellular baseband processor of the wireless device selects and configures the shared provisioning eSIM with IMSI values based on the priorities and on results from scanning for available public land mobile networks (PLMNs). The shared provisioning eSIM can be re-configured with different IMSI values selected from different IMSI pools until successful registration using the configured provisioning eSIM occurs or a maximum number or retries occurs.

On-device shared provisioning SIM/eSIM controller for a wireless device

This application describes managing configuration of a bootstrap electronic SIM (eSIM) for a wireless device. A bootstrap eSIM on an embedded universal integrated circuit card (eUICC) of the wireless device is configured as needed to provide cellular wireless access. The bootstrap eSIM is configured with an initial international mobile subscriber identity (i-IMSI) value used to establish a cellular connection to obtain a bootstrap IMSI (b-IMSI) value allocated for temporary, dedicated use by the wireless device. The b-IMSI value is selected by a bootstrap server based on a bootstrap selection rule obtained from a bootstrap rules service, where the bootstrap selection rule accounts for a use case type provided by the wireless device and indicating a purpose for use of the b-IMSI value. The b-IMSI value is returned to a pool for use by other wireless devices after expiration of a timer or responsive to a delete notification message.

This disclosure relates to techniques for a wireless device to determine whether to display an indicator of millimeter wave cellular availability. A wireless device may establish a radio resource control connection that includes connectivity with a fifth generation new radio millimeter wave cell. The wireless device may determine to display an indication of millimeter wave cell availability. The wireless device may determine location status information and motion status information for the wireless device. The wireless device may determine when to cease displaying the indication of millimeter wave cell availability after the radio resource control connection is released or the millimeter wave cell is deconfigured based at least in part on the location status information for the wireless device and the motion status information for the wireless device.

Determining whether to display an indicator of millimeter wave cellular availability

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.

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

A device and method for a user equipment (UE) to implement power savings mechanisms when operating within a significant location. The UE identifies that the UE is at a significant location. The significant location is a location relative to a currently camped cell of a network. At a first time and at the significant location, the UE performs a type of operation related to the network connection. The UE stores information corresponding to the performance of the type of operation at the first time in a profile associated with the significant location. At a second time and at the significant location, the UE performs the type of operation related to the network connection. The performance of the type of operation at the second time is modified based on the information stored in the profile associated with the significant location.

System enablers for multi-sim devices

An accessory device may dynamically determine to transition a cellular connection between mobile-initiated communication only (MICO) mode and non-MICO mode based on a variety of factors. The accessory device may be configured to communicate through a non-cellular network in addition to the cellular network. The accessory device may transition from MICO to non-MICO mode based on one or more of: loss of the non-cellular connection; location of the accessory device; a call, data, or SMS request failure over the non-cellular network; or other factors.

Intelligent baseband operating mode selection for 5G based device

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.

5G new radio de-registration procedures

Apparatuses, systems, and methods for user equipment (UE) devices to perform more efficient frequency scans for potential base stations. According to techniques described herein, the UE may determine that it does not have cellular service and determine first information based on a last camped cell. A time period during which the first information was acquired may be determined and one or more frequency scans may be performed. The frequency scans may be limited to a set of frequencies based in part on the time period. Thus, if the time period is less than a first value, the set of frequencies may include a first set of frequencies and if the time period is greater than the first value but less than a second value, the set of frequencies may include the first set of frequencies and a second set of frequencies.

Cellular system selection frequency scan scope

This disclosure relates to energy budgeted cellular service recovery techniques. A wireless device may determine one or more energy budgets for service recovery. It may be determined that cellular service loss is currently occurring. Cellular service recovery may be attempted, where service recovery scan timing for the attempt to recover cellular service is determined based at least in part on the one or more energy budgets for service recovery.
