ESTABLISHING A DEDICATED CONTROL PLANE TUNNEL

摘要

A method is for use in a system comprising a first network node, a second network node, and a terminal device, in a case where the terminal device has a connection to the second network node over a radio interface and the first network node has a connection to the second network node over an inter-node interface. A dedicated control plane tunnel is established, for sending dedicated messages, between the first network node and the terminal device over the inter-node interface and the radio interface.
