<p>A mobile communications system is described in which the network configures a mobile relay node (RN) that is mounted in a moving vehicle (such as a train). In particular the invention lies in relay services used in LTE advanced systems. It aims to provide a way to inform the network about the change of tracking area (TA) of UEs connected via a mobile RN. The invention contributes a relay node of a communications system that has a plurality of base stations and sends to a base station, a relay node identifier when the relay node connects to the base station. It receives a connection message from an associated user device, inserts the relay node identifier into the received connection message and transmits the connection message to the base station.</p> |
