  • Patent number: 10231262
    Abstract: A wireless device (202) is assisted by an access point (200) to perform contention based access on a radio channel for uplink transmission to the access point (200). The access point (200) obtains (2:1) a traffic load L on the radio channel and determines (2:2) a sleep window based on the traffic load L so that the sleep window increases when the traffic load L increases. The access point (200) then signals (2:3) the sleep window to the wireless device to instruct the wireless device to apply (2:4b) sleep mode according to the sleep window when the wireless device senses (2:4a) that the radio channel is busy. Thereby, the risk for congestion on the radio channel can be reduced during high traffic load and the energy consumption can also be reduced in the wireless device.

A wake-up message is sent from an instigator at the primary node to a receptor at a said secondary node. The communications channels with the receptor at said secondary node are periodically sniffed for a valid wake-up message. In response to reception of a valid wake-up message the receptor places the secondary node in the wake-up state. The instigator and receptor employ a selected operational mode being defined by the timing of the wake-up message and sniff pattern at the receptor.

The network device then dynamically selects a DTIM interval for the AP based on the characteristics for the at least one client device, and configures the AP to transmit a DTIM beacon frame at a frequency based on the dynamically selected DTIM interval. Alternatively, the network device can determine one or more characteristics for a client device, and dynamically select a Virtual Access Point (VAP) for providing network access to the client device based on the characteristics for the client device and a DTIM interval configured for the VAP, and then cause the client device to connect to the VAP.

  • Patent number: 9191442
    Abstract: A method for controlling a sensor may be performed by a mobile device including a processor and a memory. The method may include receiving raw data from the sensor, classifying the raw data into a context value, interpreting the context value into a higher-level context, receiving a predicted context based on the higher-level context, and controlling the sensor based on the predicted context. Controlling the sensor may include controlling a frequency at which raw data is received from the sensor, or an on/off state of the sensor. Control of the sensor may also be based on both the higher-level context and the predicted context.

  • Patent number: 9001723
    Abstract: A method and system for managing broadcast of notifications indicating whether system information has changed, so as to enable served devices to determine when to read and store updated system information. A radio access network tracks changes in system information on a per wakeup cycle basis, so as to determine whether system information has changed since a last instance of broadcasting such a notification in a particular wakeup cycle. If system information has changed, the network responsively broadcasts an indication that system information has changed, so as to cause devices operating on that wakeup cycle to read and store the updated system information. Whereas, if system information has not changed, the network responsively broadcasts an indication that system information has not changed (or forgoes broadcasting an indication that system information has changed), so that devices operating on that wakeup cycle can avoid reading and storing the system information.

    Abstract: Aspects of a method and system for physical layer control of low latency state transitions for energy efficiency. In this regard, a determination may be made to reconfigure a network device from an energy saving mode of operation to a higher performance mode of operation. A first portion of the network device may be reconfigured prior to sending an indication of the reconfiguration to a link partner, and a remaining portion of the network device may be reconfigured after sending the indication. The link partner may begin reconfiguration from an energy saving mode of operation to higher performance mode of operation upon receiving the indication. The energy saving mode may comprise a low power idle (LPI) or a subset PHY mode. The reconfiguration may comprise allocating memory to, and/or de-allocating memory from, buffering received and/or to-be-transmitted data.
