Classification: CPC H | IPC H

Claim 14:
15. A system for caching content in a cellular telecommunications network, comprising:
a processor at a coordinating server in the telecommunications network;
a memory electrically coupled to the processor;
a first network node acting as a base station and assigned as a primary slave caching node to cache content for a user equipment (UE) attached to a first base station, the first network node being selected for having sufficient number of links or sufficient bandwidth for caching the content to be streamed to the UE at a first time, the first network node having a first overlay network address for use for caching purposes; and
a second network node acting as a base station and as a caching node and communicatively coupled with the first network node and the coordinating server,
the coordinating server for determining the UE has moved from the first base station to a second base station and determining whether the first network node should continue to act as the primary slave caching node for the UE after it has moved to the second base station;
the first network node continuing use as the primary slave caching node when the determination is that the first network should continue to act as the primary slave caching node for the UE; and
the second network node used as the primary caching node to cache content for the UE attached to a second base station when the determination is that the first network should not continue to act as the caching node for the UE and that the second network node being selected for having sufficient number of links or sufficient bandwidth for caching the content to be streamed to the UE at a second time, the second network node being caused to reuse a same overlay network address of the primary slave caching node so that the UE can continue to use the same overlay network address for caching,
wherein the first and second network nodes are located in a Radio Access Network (RAN).
