  • Patent number: 8199731
    Abstract: A method and apparatus for establishing data connections between multiple networks is provided. A portable, electronic device 300, such as a mobile telephone, includes a communication module 303 configured to initiate the data connection by transmitting an initiation request. The device 300 establishes the data connection, which may be a packet data protocol-context data connection in a general packet radio service environment, by transmitting an initiation request that includes a network identifier such as access point name to obtain an Internet protocol address. Upon determining available network channels suitable for establishment of the network connection, a processing module 304 selects a corresponding network identifier from a look-up table 305 of network identifiers and corresponding networks. The communication module 303 then transmits the data connection initiation request having the selected network identifier so as to establish a switched packet data connection with the selected network.

  • Patent number: 8019012
    Abstract: A communication controller and a method is provided for synchronizing a wireless communication device and a wireless communication network having two or more transmit antennas, which support transmit diversity. A reference signal is received from the wireless communication network via each one of a pair of the two or more transmit antennas. A preferred phase offset is then determined for the pair of transmit antennas, and then transmitted to the wireless communication network. Further adjustments of the requested phase and amplitude of the communications transmitted using the pair of transmit antennas are suspended, until further transmissions are received from the wireless communication network via the corresponding transmit antennas, which can be decoded in accordance with the preferred phase offset or a timer has elapsed corresponding to the maximum time needed for the wireless communication network to receive the preferred phase offset and synchronize to the same.

  • Patent number: 7899051
    Abstract: The present invention provides a broadcast channel signal, a wireless communication device and method for transmitting broadcast channel information, where an invariant subportion of a variant portion of the broadcast channel information is separated from the variant subportion of the variant portion and combined with the invariant portion, and encoded separately from the variant subportion. Both encoded portions are transmitted and decoded by a wireless communication device, which uses subsequent transmissions of the broadcast channel information to assist in the decoding in the event the broadcast channel information for a particular transmission frame of a transmission interval cannot be decoded.

  • Patent number: 7734549
    Abstract: A system and method to securely create, distribute, install and execute selected features of software on wireless devices combines three different types of licenses, a validation license, a digital rights management (DRM) license, and a feature license with a software application. Each of these three licenses work independent of each other, where the validation license helps prevent malicious code from executing on wireless devices, the DRM license prevents unauthorized copying of the software application and the feature license securely enables or disables specific features of the software application. The system also allows a wireless device to unwrap a DRM protected software application, to validate the software application, to enforce DRM usage rules and to execute selected features of the software application.

  • Patent number: 7672381
    Abstract: A method (20) of orthogonal frequency-division multiplex (OFDM) communication via a plurality of subchannels (30) within a noncontiguous wideband channel (24) is provided. The method (20) determines an SNR for each of the subchannels (30). The method (20) then designates a subchannel (30) as clear (93) when its SNR is greater than a least-SNR threshold (70), as impeded (95) when its SNR is less than the least-SNR threshold and greater than an SNR-evaluation threshold, and as obstructed (111) when its SNR is less than both the least-SNR and the SNR-evaluation thresholds. The method (20) then transmits OFDM data (34) so that each of the clear subchannels receives the OFDM data (34) at a maximum subchannel signal level (40), each of the impeded subchannels receives the OFDM data (34) at an intermediate subchannel signal level (42), and each of the obstructed subchannels receives the OFDM data (34) at zero subchannel signal level (44).

  • Patent number: 7672594
    Abstract: An optical communication system is provided for conveying signals between multiple housing elements of a device, where respective optical detectors and optical light sources interact via a light guide associated with each communication path, where an optical signal produced by the optical light source and received by the optical detector travels a path where at least a first light redirection unit redirects the optical signal between an angle in which the optical signal travels along at least a portion of the length of the light guide, and an angle which allows the optical signal to exit the light guide. In at least some instances, the multiple housing elements correspond to at least a pair of housing elements that are incorporated as part of a communication device having a slider configuration. In some of the same or still further instances, one or more of the light redirection units are diffractive optical elements. In some instances, one or more of the light redirection units are reflectors.
