  • Publication number: 20120120828
    Abstract: A wireless network (e.g., an LTE network) may be configured to monitor a communications interface to set an inactivity timer that, in turn, sets the operating mode of a communications interface. The operating mode may include a time-domain reception pattern of the wireless device. A wireless device may monitor a communications interface that includes at least a first logical channel and a second logical channel. Based on monitoring the communications interface, a first activity state for the first logical channel may be determined and a second activity state (e.g., an activity status) for the second logical channel may be determined. An inactivity timer used by the communications interface may be set to a first value or a second value based on the first and second activity states. The battery life of a wireless device may be preserved by setting an inactivity timer responsive to how the wireless device is used.

  • Publication number: 20110170410
    Abstract: A method, apparatus, and computer program product for responding to congestion levels in a communication system by rate adaptation. A congestion condition is indicated by marking data packets. In response to receiving an indication of congestion, a data rate is reduced.
