Classification: CPC H | IPC H

Claim 7:
8. A non-transitory computer-readable medium containing instructions which, when executed, cause a system to perform steps comprising:
configuring an overlay network with overlay network addresses for use by a caching network;
assigning a first network node 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;
determining, by a coordinating server, the UE has moved from the first base station to a second base station;
determining, by the coordinating server, 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;
continuing use of the first network node as the primary slave caching node when the determination is that the first network node should continue to act as the primary slave caching node for the UE; and
designating a second network node as the primary slave caching node to cache content for the UE attached to a second base station when the determination is that the first network node should not continue to act as the primary slave 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).
