    Abstract: A system, apparatus, and method for transmitting data in a broadcast mode to multiple devices operating in a network. The invention enables the efficient utilization of bandwidth while providing a desired level of quality of service for the applications executing on the devices that utilize the broadcasted data. The invention utilizes a set of bandwidth constraints in combination with a set of heuristics and rules for the allocation and re-allocation of bandwidth among multiple applications in a manner that minimizes the impact on the quality of service metrics of importance to the affected applications when contention exists for the network resources. The present invention implements processes to cause the quality of service provided to each application to degrade smoothly, with certain priorities and guarantees being maintained.

  • Publication number: 20060126556
    Abstract: A technique for content delivery in wireless networks which associates a desired broadcast/multicast (BCMC) territory with the content, estimates cell sector coverage area from a subscriber location data set, and then identifies a set of cell sectors to be sent the content using a BCMC protocol. The method involves first receiving a description of a designated broadcast/multicast (BCMC) territory in terms of a physical area. Next, a content indicator associated with the BCMC territory is identified. The content indicator identifies content, such as text or image data, that is to be supplied to subscribers located in the territory. A cell sector coverage area is then estimated from a subscriber location data set wherein the data set includes at least a geographic location and a cell sector identifier for multiple subscribers. The BCMC territory description and the estimated cell sector coverage areas are then compared against the subscriber location data set to identify a set of targeted cell sectors.
