DYNAMIC CONTENT BASED MULTICAST ROUTING IN MOBILE NETWORKS

摘要

The present invention changes the wireless information service paradigm from a connection−oriented unicast network model to a dynamic content−driven multicast model using a technique called "content routing." The present invention provides a system, method, and medium for routing content (105) through a network from at least one content provider (100) to at least one content consumer (150), wherein at least one of the content consumer (150) or content provider (100) communicate with the network using a wireless device. The content is routed though the network based on its content. The content is labeled with at least one content descriptor (110). The content descriptor (110) characterizes or otherwise describes the content (105). Interest profiles (125) are received from content consumers (150). Interest profiles (125) from content consumers (150) with a common network access point are aggregated into a single interest profile. Interest profiles (125) can include more than the wireless consumers stated interest, such as for example, a content consumer's geographic location, the capabilities of the wireless terminal, type of service, policy preferences, and the like. Single interest profiles are shared across neighboring network access points to create a content routing table. Content, labeled with at least one descriptor, is routed through the network (140) to content consumers (150) based, in part, on content routing tables created from wireless content consumers' profiles.
