    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: 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.
