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: 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.
