  • Patent number: 9955425
    Abstract: Methods and devices may select a particular radio access technology (RATs) available on a multi-technology wireless communication device to support a user activity based on monitored device usage patterns and power consumption profiles of the various RATs. Various embodiments may enable multi-RAT wireless communication devices to monitor the usage patterns of each service (i.e., wireless communication link) provided by the device, and estimate the power consumption during the user activity based on the power needs of services and the user activity. A multi-RAT wireless communication device may determine whether switching, enabling, or disabling services and/or RATs would reduce power consumption. Thus, the wireless communication device may extend the time that a user can perform a user activity when battery reserves are low by switching to a lower-power RAT and/or disabling power-hungry services.

    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.

  • Patent number: 8965462
    Abstract: Personal digital assistant devices are provided that query power subsystems to determine a level of battery power currently available for operating processes, and further determine a number of screen display changes that may be effected on a persistent display device at that determined level. If the determined number of screen display changes that may be effected at the determined level of available battery power fails to meet a specified minimum threshold number of images, the processing unit powers down subsystems of the personal digital assistant device and causes a highest listed image of a prioritized list of screen image instances to be displayed on the persistent display device, which persistently displays the image after a loss of power.

  • Patent number: 8958854
    Abstract: A user can manage battery consumption of a mobile device using a mobile device battery management program which provides improved battery management functions, such as a dynamic battery use estimator, a battery threshold manager, and a profile based battery manager. Using the dynamic battery use estimator, the user can input different configuration settings of the mobile device and get estimates of the projected remaining battery life for the inputted configuration settings before applying any change to the operational configuration setting. The battery threshold manager allows the user to select a trigger and set its associated condition for turning off at least one application, service, or component of the mobile device when the condition is reached. Using the profile based battery manager, the user can select one of multiple profiles and set the mobile device to operate in an operational configuration setting corresponding to the selected profile.

  • Patent number: 8958398
    Abstract: Time division multiple access (TDMA) media access control (MAC) adapted for single user, multiple user, multiple access, and/or MIMO wireless communications. Various com systems may include smart meter stations (SMSTAs) and/or wireless stations (STAs). Appropriate coordination is made with respect to such communication devices to ensure appropriate uplink (and/or downlink) communications between a network manager or coordinator (e.g., an access point (AP)) and the SMSTAs and/or STAs. With respect to SMSTAs, the relative duration of time that such communication devices are awake and operative versus asleep (or in a reduced power and/or functionality state) can be significant. Certain implementations may include a relatively large number of such communication devices (e.g., 10s, 100a, 1000s, or more), and appropriate coordination and scheduling of such communications to/from them is made using one or more variations of TDMA signaling (e.g.

  • Patent number: 8954070
    Abstract: A method and system for selecting a communication network by a wireless communication device (106) includes receiving (310) an identification parameter at the wireless communication device from a communication network which identifies the communication network. Next, the method compares (312) the identification parameter with a list at the wireless communication device to determine (314) service information. The service information identifies the services supported by the communication network. The method further includes comparing (316) the service information with a service-related datum at the wireless communication device that indicates the services desired by the wireless communication device. Lastly, the method includes selecting (318) the communication network for accessing a requested service if the service information matches the service-related datum.

  • Patent number: 8913536
    Abstract: The present invention provides a DRX control method and system in which power consumption of a mobile station can be reduced and an increase in the load of a network can be suppressed. A source base station forwards Dormancy Context, which is information for controlling the activity level of a mobile station that performs inter base station handover, to a target base station and, immediately after the mobile station completes handover, the target base station performs DRX control of the mobile station using the Dormancy Context.

  • Patent number: 8902802
    Abstract: Disclosed are a terminal device for receiving a signal in a wireless communication system for supporting a plurality of component carriers and a method thereof. In the terminal device for receiving the signal in the system for supporting the component carriers, a receiver receives a Physical Downlink Control Channel (PDCCH) including control information of a first type component carrier from a base station or a relay. A processor performs a decoding operation or controls an operation in a slip mode on the basis of control information included in a PDCCH in a second type component carrier after a time corresponding to a particular time offset value passes from a transmission time point of the PDCCH.
