1. A method of providing information to a core network where a terminal exchanges data with a cache located in a node in an
access network, the method performed by the node and comprising:
storing data in the cache;
determining whether the terminal is roaming in a network other than a home network of a subscriber associated with the terminal;
in the event that the terminal is not roaming in a network other than the home network of the subscriber associated with the
terminal, allowing an exchange of data stored in the cache between the cache and the terminal; and

providing information relating to the data stored in the cache that was exchanged between the cache and the terminal to the
core network,

wherein the determination of whether the terminal is roaming in a network other than the home network of the subscriber associated

the home network and identifying a Public Land Mobile Network identifier within an international Mobile Subscriber Identity
