  • Patent number: 9479950
    Abstract: In one aspect of the teachings herein, network-side and device-side methods and apparatus identify a subset of frequency layers on which a wireless device performs regular inter-frequency scanning. The subset is identified from among a set of frequency layers that are candidates for inter-frequency measurement by the device. In an example, the wireless device scans the set of frequency layers and the corresponding scan results are used to select the best frequency layers in the set. In turn, the wireless device performs regular inter-frequency measurements on the frequency layers in the selected subset. Scanning thus can be understood as a mechanism for intelligently selecting preferred ones among a number of frequency layers that are candidates for inter-frequency measurement by the device.

    Abstract: An method, apparatus and machine readable medium are described for intelligently selecting a network interface. An attempt may be made to connect over a first network interface having the highest priority (e.g., WiFi). At the same time, a fallback timer is started. If the attempt to connect over the first network interface does not succeed within a designated timer threshold, then a parallel attempt is made to connect over a second network interface having a lower priority (e.g., cellular). The first network interface over which a connection is successfully made is then used. These techniques may be employed on a per-connection basis. Thus, a first process may successfully connect over the first network interface while a second process may be unsuccessful over the first network interface but may fall back to the second network interface.

Alternatively, the networked device management system is in communication with the networked devices via a controller located in proximity to the networked devices. A networked device is an addressable device that is capable of communicating with networked device management system. The networked device management system allows users to control the state of the user's networked devices that are registered with the networked device management system. That is, the networked device management system affords user control over the functional capabilities of the user's networked device. Networked devices of a user may be located in different geographical locations yet are still user controllable via the networked device management system. Thus, a user does not need to be in the proximity of the networked device in order to control the functional capabilities of the networked device.

  • Patent number: 9414430
    Abstract: Certain aspects of the present disclosure relate to techniques for managing radio link failure recovery for a user equipment (UE) connected to a WWAN and a WLAN. The techniques may include establishing communication with a first radio access technology (RAT) and a second RAT. At least one data flow may be transmitted over each of the first RAT and the second RAT. Determinations may be made as to whether to maintain the at least one data flow over the second RAT when a radio link failure (RLF) is detected at the UE and/or whether to resume the at least one data flow over the second RAT upon RLF recovery. The determinations may be made at the UE, at a network entity in communication with the UE, or some combination thereof.

  • Patent number: 9414320
    Abstract: To provide appropriate communication quality between a radio station (e.g., small-scale base station) and a mobile station in a state where the radio station is located within a large-scale cell and communicates with the mobile station while reducing interference exerted on the large-scale cell by communication between the radio station and the mobile station regardless of the place of the radio station within the large-scale cell. A femto base station 4 sets a target received power RTWP_target of uplink data used for controlling transmission power of uplink data transmission from a mobile station on an uplink based on a measurement result of received power Pmacro of a pilot signal transmitted from a macro base station 3. Specifically, the target received power RTWP_target is preferably set to a larger value as the received power Pmacro of the pilot signal becomes smaller.

    Abstract: A technique for transmission of wireless signals across CDMA radio links. Bandwidth is allocated dynamically within a session to specific CDMA subscriber unit based upon data rate determinations. Specifically, a dynamic bandwidth allocation algorithm operates from limits calculated based upon available ports per subscriber, expected user bandwidth, and parallel user bandwidth versus throughput. Provisions for priority service, unbalanced forward and reverse spectrum utilization, voice prioritization, and band switching are also made.

  • Patent number: 9398591
    Abstract: Methods and apparatus for improved utilization of air link resources are discussed in wireless communications systems employing multi-sector base stations and wireless terminals with multiple antennas. Timing synchronization is maintained across the base station sectors, and the same set of tones are used in adjacent sectors. In a sector boundary region, which is typically a high interference region, a wireless terminal is set to a sector pair state and operated in a MIMO mode of operation, communicating with two adjacent base station antenna faces of the same base station concurrently, the two different adjacent base station antenna faces corresponding to different adjacent sectors. Thus, typically high interference sector boundary regions, are converted into high capacity regions by having the sectors coordinated and utilizing MIMO techniques.

  • Patent number: 9397804
    Abstract: An idle mode load balancing capability enables balancing of idle mode wireless devices across wireless carriers in order to ensure that the possibility of congestion on any given wireless carrier is reduced or even minimized when idle mode wireless devices become active. The idle mode load balancing may be performed for wireless carriers by determining relative numbers of idle mode wireless devices on the wireless carriers and performing idle mode load balancing for the wireless carriers based on the relative numbers of idle mode wireless devices on the wireless carriers. The relative number of idle mode wireless devices on a wireless carrier may be determined based on a change in load on the wireless carrier during the observation period, which may be determined based on an observed change in load on the wireless carrier and a load correction associated with session terminations on the wireless carrier.

  • Patent number: 9398120
    Abstract: A method and apparatus are used to support the transmission of data to a user over multiple allocated data channels. Data packets are transmitted in timeslots of the allocated data channels to corresponding target receivers without the need for explicitly assigning particular time-slots to a target user well in advance of transmitting any data packets in the time-slots. Instead, each data packet transmitted in a time-slot includes a header label or preamble indicating to which of multiple possible receivers a data packet is directed. The preamble also preferably includes decoding information indicating how a corresponding data payload of the data packet is to be processed for recapturing transmitted raw data.
