Abstract: Access class barring can provide latency for accessing a barred service using a radio access technology (RAT) due to congestion of a local cell accessed via that RAT. A user equipment (UE) supports multiple RATs and the same service may be accessible via a separate cell accessed using a different RAT. Various aspects of the present disclosure describe techniques for configuring the UE to selectively switch between RATs to access a service based on a barring factor employed for a particular RAT, thereby reducing latency for accessing the service. The UEs may operate to monitor a current value of a barring factor for a service the UE seeks to access via a preferred, or default, RAT. In the event that the current value of the barring factor exceeds a specified threshold, the UE switches over to using a different RAT to access this service.

Abstract: A user equipment (UE) employing different radio access technologies (RATs) concurrently or successively provides the UE the opportunity to select a particular RAT to support an access service used by one or more software applications of the UE. A RAT operational control scheme provides for opportunistic enablement and disablement of a RAT and/or intra-RAT configuration so as to provide sufficient uplink and downlink throughput for supported software applications while reducing unnecessary power consumption by the UE, which often is battery powered.

Abstract: At switch-on or when recovering from lack of coverage, a UE determines first frequency bands corresponding to an initial MCC of a country in which the UE currently is located (402). The frequency bands include a first set of frequency bands associated with a network carrier to which the UE is subscribed and a second set of frequency bands not associated with the network carrier (404). The UE scans the first set of frequency bands (406). In response to detecting a new MCC and determining that no service is available within the first set of frequency bands (408), the UE scans a third set of frequency bands preferred by the UE within a second plurality of frequency bands corresponding to the new MCC (410). In response to determining that no service is available within the third set of frequency bands, the UE scans the second set of frequency bands (412).

Abstract: A UE performs up to a threshold number of attempts to transmit a default capability message to a base station, the default capability message representing a default set of CA combinations supported by the UE. If transmission is unsuccessful, the UE switches to a compact capability mode in which the UE attempts to transmit compacted UE capability messages representing successively smaller subsets of the default set of CA combinations until either a capability message is successfully received by the base station or a second threshold number of unsuccessful transmission attempts is performed. To facilitate configuration of an initial compacted capability message, the UE maintains a PC list that lists one or more cells that have been identified previously as incapable of receiving default-sized capability messages and that further identifies a representation of a limited subset of CA combinations to include in capability messages sent to a corresponding listed cell.

Abstract: Apparatus and methods related to acquiring service on mobile computing devices (MCDs) are provided. A method includes determining a decreasing sequence of scan ratios, each scan ratio indicating a proportion of time over which a MCD scans one or more frequencies to attempt connection with a wireless network during a disconnected time window. The method further includes determining a connected time window′ when the MCD is connected to the wireless network. The method additionally includes determining a ping-pong rate for the MCD based at least on a duration of the connected time window. The method also includes selecting a scan ratio from the decreasing sequence of scan ratios based on the ping-pong rate. The method further includes scanning the one or more frequencies in accordance with the decreasing sequence of scan ratios and starting from the selected scan ratio to cause the MCD to attempt connection with the wireless network.

Abstract: A user equipment (UE) reduces power consumption by selectively disconnecting from a radio access network (RAN) while in a non-standalone (NSA) mode in response to detecting a threshold number of communication failures associated with the RAN. The UE connects to a core network in the NSA mode via both a 4G RAN and a 5G RAN. The UE monitors the connection with the 5G RAN for communication failures, such as Random Access Channel (RACH) failures, radio link failures (RLFs), and the like. In response to the number of detected failures exceeding a threshold, the UE can determine that the quality of the connection with the 5G RAN is providing relatively little benefit and can terminate the connection with the 5G RAN.

Abstract: The subject matter described herein provides systems and techniques to automatically configure a proximal device, such as a smart watch, a tablet, or any other smart device, based on configuration information sent from the user equipment (UE) to the proximal device when the local communications connection, such as a wireless connection, between the devices is weak. If it is determined that there is a weak local communications connection between the UE and the proximal device the UE may automatically send network configuration information to the proximal device. If it is determined that there is a weak local communications connection between the UE and the proximal device the UE may automatically turn on its mobile hotspot, and automatically send the mobile hotspot configuration information to the proximal device.

Abstract: A component of a cellular user equipment (UE) device is configured to detect adverse radio link conditions. The component monitors a plurality of layers of a communication stack of the UE device during an active voice call. Responsive to monitoring the plurality of layers, the component detects at least one adverse radio link condition associated with the active voice call. The component provides a radio link degradation indication to a second component of the UE device in response to detecting the at least one adverse radio link condition.

Abstract: The present disclosure describes apparatuses and techniques of adaptive PLMN management for varying network conditions. In some aspects, a PLMN manager of a user equipment (UE) searches, as part of a registration procedure, a data repository of PLMN information that includes a PLMN blocked from registration for a duration of time and determines that the PLMN is blocked due to a signal-related condition with a cell of the PLMN (e.g., weak signal). The PLMN manager then determines, during the duration of time, that the signal-related condition between the UE and the cell has improved. In response to the improvement, the PLMN manager unblocks the PLMN before expiration of the duration of time. By so doing, the UE may reattempt registration with the unblocked PLMN at least once before the duration of time expires, which may allow the UE to register more quickly and reestablish network services.
