Abstract:
A method is provided which introduces user plane caching over an interface between a first node in a radio access network and a second node in a core network. At the first node: receiving first uplink tunnel parameters relating to the second node, selecting first downlink tunnel parameters relating to the first node, sending the first uplink and downlink tunnel parameters to a cache node designated to the first node, receiving second uplink and downlink tunnel parameters relating to the cache node, and sending the second downlink tunnel parameters to the second node. A first tunnel is established between the first node and the cache node based on the second uplink tunnel parameters and the first downlink tunnel parameters, uplink user plane data is sent to the second node through the first and second tunnels via the cache node, and downlink user plane data is received from the second node.
