<p>A method of delivering data to user terminals connected to an Internet Protocol Connectivity Access Network, IP-CAN, wherein the IP-CAN implements a Policy and Charging Control, PCC, architecture. The method comprises caching data within an IP-CAN cache server upon a decision made by a Policy and Charging Rules Function, PCRF, of the PCC architecture. The cached data is then identified to a Policy and Charging Enforcement Function, PCEF, of the PCC architecture. At the PCEF, data requests made by user terminals are monitored and a determination made as to whether or not a request relates to cached data. If a request does relate to cached data, then that cached data is delivered from the IP-CAN cache server to the requesting user terminal.</p> |
