摘要： 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.

摘要： Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for enhancement of multi-SIM devices, such as UE 106. 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.

摘要： 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.

摘要： 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.

摘要： A user equipment (UE) indicates to a network the types of SMS messages that the UE does not support. The network receives an indication from the UE corresponding to one or more types of short message service (SMS) messages that are supported by the UE, receives a SMS that is intended to be delivered to the UE, determines whether to forward the SMS message to the UE based on the indication received from the UE, when the SMS message is a type of SMS message supported by the UE, forwards the SMS message to the UE and, when the SMS message is not a type of SMS message supported by the UE, discards the SMS message.

摘要： Methods and devices for a user equipment (UE) device to utilize an electronic subscriber identity module (eSIM) to provide backup cellular connectivity for essential services and security enhancements. A UE device receives user input to alter an operational state of the UE. The user input may include removing a physical subscriber identity module (SIM) card installed in the UE or attempting to power off the UE. In response to receiving the user input, an authorization process is initiated. In response to determining that the authorization process has failed, a security enhancement is implemented for the UE.

摘要： A user equipment (UE) passively determines the presence of a cellular network bottleneck in a downlink channel and may take appropriate actions to mitigate the bottleneck. The UE may analyze the transport block size (TBS) of slots of received downlink traffic and assign states the to various slots based on this analysis. Based on these assigned states, the UE may identify a burst of network traffic from network traffic received from the cellular network, and the UE may also determine the burst duration as well as a busy estimation. The UE may determine that the cellular network is experiencing a bottleneck based at least in part on the burst duration and the busy estimation.

摘要： 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.
