  • Patent number: 7920860
    Abstract: The Multi-Link Aircraft Cellular System makes use of multiple physically separated antennas mounted on the aircraft, as well as the use of additional optional signal isolation and optimization techniques to improve the call handling capacity of the Air-To-Ground cellular communications network. These additional techniques can include polarization domain and ground antenna pattern shaping (in azimuth, in elevation, or in both planes). Further, if code domain separation is added, dramatic increases in capacity are realized. Thus, the Air-To-Ground cellular communications network can increase its capacity on a per aircraft basis by sharing its traffic load among more than one cell or sector and by making use of multiple physically separated antennas mounted on the aircraft, as well as the use of additional optional signal isolation and optimization techniques.

  • Publication number: 20110038332
    Abstract: The present disclosure includes systems and techniques relating to wireless communications. A described system, for example, includes a device configured to transmit signals, in a frequency band, to the wireless communication devices. The signals can include spatially steered first signals that concurrently provide data to the wireless communication devices.

  • Publication number: 20110022660
    Abstract: A new P2P streaming method and apparatus disseminates video chunks to all peers with the minimum (or at least reduced) delay. After obtaining a new video chunk, a peer keeps transmitting (uploading) that video chunk to other peers until all peers receive it. The approach quickly increases the aggregate bandwidth that can be utilized to transmit a video chunk. For example, the aggregate peer bandwidth used to transmit a video chunk can double every time slot. For a homogeneous P2P streaming system with N peers, a time slot is defined as a unit of the single chunk transmission delay between two peers. Using the P2P streaming method, a video chunk can be disseminated to all peers within 1+log2 N time slots.

  • Publication number: 20110007884
    Abstract: The present invention proposes a method and apparatus for providing a user with notification information during a call period in a telecommunication system based on SIP protocol. In the present invention, after receiving a calling response message from a network server, a user equipment retrieves notification information from the calling response message and presents it to the user by a display screen (e.g. the display screen of a cell phone). If there needs several communications between the user equipment and the network server, the user only needs to choose corresponding service according to the notification information presented on the display screen, wherein the notification information presented on the display screen comprises one item or a plurality of items for the user to choose. It saves time and avoids the misoperation due to the fact that the user didn't listen to the voice notification information clearly.

  • Publication number: 20100333185
    Abstract: An apparatus and method establish a secure, direct, station-to-station communication between a first station and a second station in a topology (e.g., PBSS) having a central secret holder/provider that allows secure, direct, station-to-station communications and that allows secure station-to-station broadcast communications. The first station and the second station will have previously established a security association (SA) with a topology control point (PCP). The method includes creating pair-wise unique material for the first station. The pair-wise unique material is computed as a function of (i) a known shared secret associated with the PCP, (ii) a first piece of unique data associated with the first station, and (iii) a second piece of unique data associated with the second station. The method includes securely communicating the pair-wise unique material from the first station to the second station.
