Abstract
A distributed caching and redistribution system, method, and mobile client for caching and redistributing data content in a wireless data network. The system enables mobile clients to cache data content that has been distributed by means of broadcast or multicast, and to redistribute the content from the cache to other users. Using anycast techniques applied to the PLMN, a user who wants to retrieve data that was distributed earlier locates the nearest user that has the content available, and asks the nearest user to forward the content. The 'nearest' user may be the closest user, but may also be the optimal user from a Quality of Service (QoS) point of view.
