  • Patent number: 8654691
    Abstract: A wireless network, such as an LTE (“Long-Term Evolution”) 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 comprise 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 (for example for a first application) and a second logical channel (for example for a second application). Based on monitoring the communications interface, a first activity state for the first logical channel may be determined. Also, based on monitoring the communications interface, 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.

  • Patent number: 8416690
    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. A rate reduction inhibit timer is started, and further rate reduction is initiated if congestion is indicated after the rate reduction inhibit timer has expired. A rate increase timer is used to initiate a rate increase if no indication of congestion is received during a rate increase time.

  • Publication number: 20130051214
    Abstract: A system and method for radio link failure recovery is presented. A set of component carriers is identified. Each one of the set of component carriers includes a control channel monitored by a user equipment (UE). The control channel signals data channel assignment information for the UE. Radio link failure recovery is performed using monitoring of only a subset of the set of component carriers. In some cases, performing radio link failure recovery includes performing radio link failure detection, and detecting radio link failure by detecting an out-of-sync condition on a downlink physical layer, the out-of-sync condition occurring for a predetermined duration. In some cases, a number of component carriers in the subset of the set of component carriers is equal to 1.

  • Publication number: 20130039287
    Abstract: A method, mobile device (101) and radio access network RAN (102) are disclosed for suspending and re-establishing a radio resource control (RRC) connection. In some examples, the mobile device (101) indicates a preference to have the RRC connection either suspended or released. In other examples, RAN (102) sends to the mobile device (101) a connection suspend command message instructing the mobile device to suspend a RRC connection with the RAN (102). The mobile device (101), in response to the connection suspend command message, suspends the RRC connection. When the RRC connection is suspended the mobile device (101) cannot transmit or receive user plane data to the RAN (102) and performs functions the same as or similar to idle mode functions. On suspension, RRC connection information is stored and can be used to re-establish the suspended RRC connection.
