Abstract: Methods and apparatus are provided for a virtual content channel structure in a broadband wireless network with location-based content. Broadband content is delivered to a mobile terminal in a wireless network by receiving a request for a content channel from the mobile terminal; and translating the requested content channel to a corresponding content item based on the requested content channel and a date and time associated with the request (and optionally, a location of the request), wherein a content source associated with the corresponding content item is transmitted to the mobile terminal using a communication channel associated with the user. The content source comprises, for example, the corresponding content item or an address or a link associated with the corresponding content item. The corresponding content item can include content components that are based on a location of the mobile terminal.

Abstract: Methods and apparatus are provided for delivering content to a mobile terminal in a wireless network. A base station in a wireless network delivers content to a mobile terminal by determining if a packet from the mobile terminal contains a request for content; and delivering the content to the mobile terminal from the base station if the content is stored locally at the base station. The base station can optionally evaluate an authorization of the mobile terminal to receive the content. During a hand-off, the current base station determines if a packet received from the mobile terminal contains a base station change message indicating that the mobile terminal is switching to a new base station; and provides content status information (such as content position) to the new base station.

Abstract: In one example embodiment of the present invention, a method of managing information at a base station in a wireless network includes determining whether first information is at least one of low priority information and high priority information. The method further includes queuing the information if the information is determined to be low priority information, and sending the information to a mobile station if the information is determined to be high priority information.

Abstract: One example embodiment of the present invention discloses a method of delivering content from a base station of a wireless network to a mobile station including receiving a request for content from a mobile station, accessing the requested content from content stored in association with the base station, and transmitting the requested content to the mobile station.

Abstract: Example embodiments provide methods of transparently migrating a reliable transport layer connection between a user and a first base station and a second base station in a wireless network. The method includes receiving at least one transport layer connection state information parameter from the first base station at the second base station. The second base station then determines at least one new transport layer connection parameter based on the at least one transferred transport layer connection state information parameter and at least one network condition at the second base station.

Abstract: A fixed codebook response is able to better characterize an input signal of a vocoder because the entries of the fixed codebook are tailored to the input signal being processed. A uniformly distributed random noise signal is stored in a transmitting vocoder. During encoding by the transmitting vocoder, the noise signal is shaped by a weighing filter and a pitch sharpening filter, which are condition controlled by the linear predictive coding, pitch and pitch gain characteristics of the input signal being encoded. The shaped noise signal is passed though a thresholding filter to arrive at a pulse sequence having a given sparcity. The fixed codebook response is chosen as that portion of the pulse sequence which best matches a residual signal of the input signal. The indexed location of that portion along the pulse sequence is designated as the fixed codebook bits which are included within the bit frame. The identical random noise signal is stored in a receiving vocoder.

Abstract: The present invention provides a method and system for characterizing the sounds of ocean captured by passive sonar listening devices. The present invention accomplishes this by first generating a spectrogram from the received sonar signal. The spectrogram is characterized in terms of textural features and signal processing parameters. The textural features and signal processing parameters are fed into a neural network ensemble that has been trained to favor specific features and/or parameters. The trained neural network ensemble classifies the signal as either Type-I or clutter.
