Abstract
A caching module is provided at the interface between a radio access network (RAN) and a core network (CN). If the requested content is available in the caching module as cached content, the caching module sends a header request upstream to an origin server to determine if the cached content is valid and authorized. If the cached content is invalid, it is evicted from the cached and may be replaced with a new, valid content. The CN can inspect the header response to perform data accounting and billing, to provide upstream content filtering, and to provide lawful interception capabilities. Related techniques are also provided.
