Abstract
The current invention is applicable to a RAN-cache or proxy operating in a wireless mobile network that is functioning as a transparent inline device intercepting wireless mobile protocols such as UMTS, LTE, WIMAX, CDMA etc.), or a traffic off-load device connected to multiple interfaces towards the Core/Internet. The current invention identifies methods for pre-fetching content by emulating portions of a mobile client for gaining connectivity through the mobile-core network, or to use session contexts of other mobile clients in a way not to significantly effect charging and billing for the preloaded content. The pre-load decision of what to pre-load and when to pre-load may be locally derived within the RAN-cache/Proxy device, or in-coordination with a locally connected CDN (Content Delivery Network) device. Other embodiments of the current invention include the RAN-cache/Proxy providing interconnectivity from the locally connected CDN device to other CDN devices through the Mobile Core Network (SGSN/GGSN in UMTS, S-GW/P-GW in LTE etc.).
