  • Patent number: 7460834
    Abstract: A method and apparatus for utilizing a switched beam directional antenna in a wireless transmit/receive unit (WTRU) is disclosed. A wireless communication system includes a serving cell, a neighbor cell and a WTRU. The WTRU is configured to generate and steer a directional beam in a plurality of directions. Once the WTRU registers with the wireless communication system, the WTRU receives messages transmitted by the serving cell. The WTRU measures signal quality of messages received in each of a plurality of predetermined directions while steering the directional beam antenna. The WTRU selects a particular one of the directions having the best signal quality. As the WTRU constantly moves, the WTRU monitors signal quality in the selected direction, and switches to another direction when the signal quality in a current direction drops below a predetermined threshold.

  • Patent number: 7389106
    Abstract: Changes in wireless service user behavior are encouraged and produced to shape utilization patterns among cells within a rate plan region by using shaping rules which define potential discounts from a standard charge rate under certain cell-specific utilization conditions, analyzing the shaping rules and utilization statistics of a cell upon service initiation, generating a discount from the standard rate for underutilized cells. The user is notified of these discount opportunities using text messages, icons, or other means. Over time, the users learn that at certain places and times, significant discounts are offered, and thus changes their behavior to take advantage of those discounts, thereby shaping traffic in a manner desired by the service provider.
