Abstract: 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.

Abstract: Methods and devices for a wireless accessory device (AD) comprising a cellular radio to communicate with a cellular network using the cellular radio. The wireless AD establishes a texting session with a network entity through the cellular network and using the cellular radio. The wireless AD initiates a countdown timer in response to establishing the texting session. The wireless AD determines that a companion device to the wireless AD is reachable by the wireless AD. The wireless AD refrains from pairing with the companion device until the countdown timer expires in response to determining that the companion device is reachable by the wireless device. After expiration of the countdown timer, if the companion device is still reachable by the wireless AD, the wireless AD may pair with the companion device and/or power down its cellular radio.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to prioritize cells that support EN-DC over similar cells not supporting EN-DC. The UE may be configured to perform one or more measurement scans associated with cell selection and/or cell re-selection and may determine whether at least two LTE cells meet a selection criteria based on RSRP and/or SNR measurements. The UE may be configured to, in response to determining that at least two LTE cells meet the selection criteria, prioritize a first LTE cell of the at least two LTE cells over a second LTE cell of the at least two LTE cells based, at least in part, on support EN-DC. The first LTE cell may indicate support of EN-DC, e.g., via a ULI IE included in a SIB2 broadcast by the first LTE cell. The UE may be configured to select the first LTE cell for camping.

Abstract: This disclosure relates to techniques for managing mobile-terminating short message service re-transmissions for wireless devices. A cellular network entity of a cellular network may receive a request to provide a short message service message to a wireless device. The wireless device may be registered with the cellular network entity via at least two access types. An attempt to provide the short message service message to the wireless device via a first access type may be performed. An attempt to provide the short message service message to the wireless device via a second access type may be performed if the attempt to provide the short message service message to the wireless device via the first access type is unsuccessful.

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.

Abstract: Apparatuses, systems, and methods for refreshing a GUTI of a UE. The UE may receive a GUTI from an AMF as part of a registration process. After a timer has expired, the UE may receive a new GUTI from the AMF. The timer may be provided by the UE as a request for use by the AMF. Alternatively, the timer may be used by the UE and the UE may request the new GUTI upon expiry of the timer, e.g., using an existing message or a new message, as desired.

Abstract: 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.

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.
