  • Publication number: 20060199544
    Abstract: A method for exploiting the diversity of a multi-carrier cellular system's frequency bands, for purposes of increasing network capacity, involves a base station transmitting a pilot signal on each frequency band to a plurality of mobile stations. Each mobile station measures the SIR of each pilot signal on the frequency bands, and this information is transmitted back to the base station. The base station may be configured to utilize this information in a number of manners, all of which are intended to increase channel capacity. For example, on each frequency band, the base station may transmit data signals only to those mobiles stations with the best signal quality on that frequency band. Additionally, the base station may transmit signals to one or more mobile stations across one or more frequency bands simultaneously, with transmissions on each band being adapted to the corresponding channel conditions.

  • Publication number: 20060199577
    Abstract: A method enables the use of a secondary pilot signal and a secondary antenna(s) in the forward link of a CDMA-based cellular network employing a slotted transmission scheme with a time-multiplexed primary pilot signal, with backwards compatibility. The forward link is divided into a number of time slots. For communications with “legacy” mobile stations that expect transmissions from a single, primary antenna (and that expect a single, primary pilot signal), during some of the time slots, only the primary antenna is used for transmissions, including transmitting the primary pilot signal. Neither the secondary pilot channel nor any other signals from the secondary antenna are transmitted. During the remaining time slots: (i) the primary pilot signal is transmitted from the primary antenna, and the secondary pilot signal is transmitted from the secondary antenna, but at different times; and (ii) data meant for the legacy mobile stations is not transmitted.

  • Patent number: 7103566
    Abstract: An executable shopping list (ESL) enables a user browsing an affiliate Web site's Web page to order, with a single action, a bundle of multiple items offered for sale by the affiliate's associated merchant Web site, wherein the bundle is one that is not offered or available for sale as a bundle to on-line visitors who directly access the merchant's Web site server. By selecting a link on the affiliate's Web page, the ESL is executed, thereby automatically loading the bundle of multiple items on that list into a virtual shopping cart at the merchant's Web site on behalf of the user. The virtual shopping cart, filled with the multiple items, is then returned to the user's browser for completion of the checkout procedure by the user. ESLs can be implemented on the affiliate site's side using what is referred to as smart bookmark technology, which records for later playback, the multiple steps required to load each item on the list into a shopping cart at the merchant's Web server.

  • Patent number: 7103884
    Abstract: A recovery process allows a recovering replica in a replicated data storage system to recover from a current replica the changes to the data that it has missed during a failure while, at the same time, the system is processing new requests issued by the source. Sequence numbers, assigned by the source to write requests and stored by each replica in association with the data item that the write request modifies, are used by the recovery process to determine when a replica has missed one or more write requests and requires recovery. During recovery, the recovering replica ignores all requests directly received from the source, and replaces the contents of a data item with the data received from the current replica only if the newly received data item has a higher sequence number than the corresponding sequence number of the data item already stored in the recovering replica. It also updates data items in response to new write requests that are forwarded to it by the current replica.

  • Patent number: 7102998
    Abstract: The operation of a multicast network is enhanced by shifting the responsibility for performing congestion control with regulation for the transmission of multicast data packets from the transmitter to the receivers, such that each receiver computes a congestion control value using particular statistics that it accumulates and then forwards it congestion control value to the source/transmitter. The source then regulates its transmission of data packets in accordance with a selected one of the congestion control values that it receives. Moreover, a hierarchical reporting network may be used to convey the regulation values from the receivers to the source such that congestion control values generated by the receivers are consolidated at various layers in the hierarchical reporting network so that the source receives consolidated control values from just the receivers connected directly to the source, rather than a value from each of the receivers.

  • Patent number: 7103635
    Abstract: A new mail transport protocol is proposed for use over a reliable byte-stream transport. This protocol is faster, simpler and more streaming than prior methods, and handles binary and unicode data more efficiently. The protocol requires fewer communication round trips between servers per message transferred than existing methods. It transmits and receives byte data as is without requiring further per-byte processing on advanced operating systems such as UNIX, and requires only new-line processing in text on legacy operating systems.

  • Patent number: 7099330
    Abstract: A scheduling apparatus flexibly integrates guaranteed-bandwidth (GB) and best-effort (BE) flows and comprises a combination of a primary weighted-round-robin (WRR) scheduler (PWS) and a secondary WRR scheduler (SWS). The PWS distributes service to the individual GB flows and determines the amount of service that the BE flow aggregate should receive during each frame. The SWS takes care of fairly distributing the service share of the BE aggregate over the individual BE flows. The scheduling apparatus divides the service frame in two subframes. In the first subframe, the PWS fulfills the bandwidth requirements of the GB flows. In the second subframe, the SWS distributes fair service to the BE flows. For each frame, the duration depends on the amount of bandwidth allocated to the GB flows and on the number of GB flows that are backlogged at the beginning of the frame. The amount of bandwidth globally available to BE flows (i.e.

  • Patent number: 7099670
    Abstract: Techniques and systems for designing a network providing communication and location identification services are described. A solution point comprising parameters for each of a plurality of base stations is generated. A coverage and locatability performance value for the solution point is computed, as well as derivatives of the performance value. The coverage and locatability performance value and its derivatives are used to indicate favorable directions for searching for subsequent solution points, and subsequent solution points are generated and compared against previous solution points until an optimum solution point is found. The coverage and locatability performance value is a weighted sum of coverage and locatability values for each point in the service area of the network, with coverage values representing forward and reverse link quality and locatability values representing the probability that a point will experience an acceptable power level from at least four base stations.
