Abstract
The invention relates to a method and entity that allow for saving of uplink bandwidth in connection with peer-to-peer sharing in a wireless communication system. A caching entity, called a reverse cache, intercepts a point-to-point connection between a mobile network user plane gateway and a wireless user equipment running a peer-to-peer application. The reverse cache caches content loaded to the peer-to-peer application and stores information indicative of the wireless user equipment to which the cached content is loaded. A request on the point-to-point connection for delivery of a first content from the wireless user equipment is intercepted by the reverse cache. When the requested first content is cached in the reverse cache along with information indicating that the requested first content has been loaded to the wireless user equipment, the reverse cache responds by delivering the requested first content, without involving the wireless user equipment.
