  • Patent number: 8270975
    Abstract: A method of managing network traffic within a wireless network (100) comprises identifying a plurality of base stations (111, 121, 131) within the wireless network, categorizing each one of the plurality of base stations according to its type, setting a load balancing parameter (?) for each one of the plurality of base stations according to its type, and, for a handover event involving a handover from a first one of the plurality of base stations to a second one of the plurality of base stations, selecting the second one of the plurality of base stations according to a process that takes into account the load balancing parameters of both the first one of the plurality of base stations and the second one of the plurality of base stations.

  • Publication number: 20110292884
    Abstract: Methods and apparatus supporting load balancing in a wireless communications system implementing decentralized control are described. Different channels, e.g., unused TV channels, are available in different locations for use for communications. Various communications technologies, e.g., WiFi, 3G Blue-Tooth, etc., may be supported by a communications device and may be allowed to be used on the available channels. A wireless communications device evaluates its current local environment, e.g., estimating potential rates that it may use and/or estimating latency, for each of a plurality of available alternative channel/technology combinations. The wireless communications device selects a channel and technology combination to use as a function of its estimates. The wireless communications device uses its selected channel and technology combination for communications, e.g., for peer to peer communications including direct peer to peer traffic signaling as part of a local peer to peer network.

  • Publication number: 20110249631
    Abstract: Various embodiments relate to using available spectrum for peer to peer communications and for selecting which of several possibly available channels should be used. Various methods and apparatus are well suited to peer to peer networks in which channel usage decisions are made in a decentralized manner. A wireless terminal generates a list of potential available channels to be used for peer to peer communications, e.g., based on FCC information and/or local sensing. Channels are filled in accordance with a predetermined channel ordering. A wireless terminal migrates between the channels in accordance with changes in the number of peer devices using a channel. The network, in a distributed manner, changes the number of channels in use at a location in response to changes in numbers of active peer devices at a location.

  • Publication number: 20110250916
    Abstract: Methods and apparatus for determining band availability and/or allocating one or more frequency bands to a communications device for wireless communications are described. In different locations and/or at different times different frequency bands, e.g., band corresponding to unused TV channels, may be available for allocation. Various described methods and apparatus are well suited for supporting local peer to peer networks in an environment in which a plurality of different technologies are supported. A centralized control device determines and allocates a frequency band to a wireless terminal for use at a given location and at a given time, e.g., for peer to peer communications using a particular technology supported by the wireless terminal. The centralized control device uses database information and information received from a plurality of wireless terminals in making frequency band allocation decisions, performing load balancing, and/or performing interference management.

  • Publication number: 20100284449
    Abstract: Examples are generally described that include methods for selecting a transmit mode in a communications system. An example method may include calculating a first transmission rate for data in a multiple-input multiple-output mode of the communications system and calculating a second transmission rate for the data in a single-input multiple-output mode of the communications system. A mode may be selected from the group consisting of the multiple-input multiple-output mode and the single-input multiple-output mode based, at least in part, on an energy consumption of the first and second transmission rates. Data may be transmitted from a transceiver in the communications system using the selected mode.

  • Publication number: 20100172291
    Abstract: A network apparatus comprises a controller to determine a first base station for transmitting data and to determine a second different base station for receiving data. In one embodiment, the network apparatus further comprises a transceiver to transmit data to the first base station while associated with the second base station. The transceiver is operable to receive data from the second base station while associated with the first base station.

  • Patent number: 6853676
    Abstract: A method for inserting and detecting a watermark based on a stochastic model is disclosed. The apparatus for inserting a watermark based on a stochastic model, includes: a generator for generating a spread spectrum signal by using a user key from outside; an estimator for estimating an autocorrelation matrix of an original signal from outside as an object for inserting a watermark; an eigenvalue decomposer for decomposing the autocorrelation matrix to an eigenvector matrix and an eigenvalue matrix; a watermark shaper for shaping a watermark from the spread spectrum signal in reference to both the eigenvector matrix and the eigenvalue matrix; and an adder for adding the watermark to the original signal.
