  • Publication number: 20110061095
    Abstract: Methods of securely performing online transactions are described which involve two independently controlled web servers. In order to complete a transaction, a user interacts concurrently with each of the two web servers and authentication may occur between the user and each web server and between web servers. Each of the two web servers provide data which is used to complete the transaction and the data provided by the first web server is communicated directly to the second web server for use in the transaction. In an embodiment, the first web server provides a web page which enables a user to specify a variable which is used in the transaction. This is communicated to the second web server which processes the transaction along with an identifier for the message. The identifier may be used in validating the variable before it is used in processing the transaction. Following completion of a transaction this may be reported in real time to the first web server.

  • Patent number: 7742788
    Abstract: In order to increase a capacity, or a number of mobile stations (MSs), or users, that may engaged in concurrent communication sessions, a communication system is provided that schedules a different MS, or user, in each beam of multiple predetermined, fixed beams associated with a coverage area, in particular a sector. By simultaneously scheduling a user in each beam of the multiple beams, a performance and throughput of communication system is significantly increased over the prior art. In one embodiment of the present invention, a portion of a shared communication channel that is allocated to each MS is concurrently transmitted to each MS via a beam associated with the MS. In other embodiments of the present invention, voice channels, data channels, and control channels associated with each MS scheduled in a beam may be concurrently transmitted to each MS via the beam associated with the MS.

  • Patent number: 7457590
    Abstract: A method, apparatus and system are provided for use in optimizing signal-to-noise ratios at remote wireless devices. A method can receive a signal over a reverse link, determine an angular power profile of the reverse link signal, and determine an antenna weighting vector for the forward traffic signal based on the angular power profile. The determination of the weighting vector can include retrieving the vector from a weighting vector table. Some methods identify boundaries of angular spreads and utilize pre-calculate weighting vectors according to the boundaries. An apparatus can include an antenna array, a wireless receiver that receives reverse link signals, a detector that detects an angular power profile of the signals, a controller that determines a weighting vector and applies the weighting vector to the antenna array when transmitting. Some embodiments are dependent on whether the forward link incorporates a common pilot or per-user pilot signal.

  • Patent number: 7272364
    Abstract: A wireless system, which minimizes nulls within the wireless system, while simultaneously providing diversity. A wireless system will now have increased capacity and coverage due to an enhanced signal to interference ratio in the areas of beam overlap. The system uses time or frequency offset on the signals input to an antenna to minimize interference in the regions of beam overlap. Additionally, polarization diversity can be introduced using Butler Matrices in conjunction with array elements to enhance the interference reduction.

  • Publication number: 20060146758
    Abstract: A communication system having spreading code resources (11) (such as, for example, Walsh codes), and upon providing (12) an initial quantity of those spreading code resources to support a voice communication by a given mobile station, then determines (13) whether to alter that initial allocation during that voice communication. For example, when the voice communication for this mobile station does not actively comprise speech, a determination can be made to allocate a reduced allotment of the spreading code resources. The system then switches (14) the new allocation of spreading code resources for the initial allocation and the mobile station continues its voice communication using the new (increased or decreased) quantity of spreading code resources.
