Abstract
A mobile communications system is described in which the network configures a mobile relay node that is mounted in a moving vehicle (such as a train) with expected tracking area information for the route along which the vehicle is expected to travel. UEs associated with the mobile relay node are provided with the list and do not perform tracking area updates if the movement of the vehicle corresponds to the stored list. Where advance knowledge of the route is not available, the mobile relay node is configured with a fixed tracking area and a fixed radio cell so that associated UEs do not detect a change in the tracking area or in the radio cell and so do not perform tracking area updates towards the network or the network does not need to control the UEs mobility while having a radio connection with the network.
