Abstract
The present invention has an object to provide a mobile communication system capable of performing communication between a user equipment device connected to a relay device and a core network if the relay device moves. An RN () sets a TA of an eNB to be connected with the own device as a TA of the own device. For example, when the RN () moves along an arrow (), the TA of the RN () is changed from a first TA () to which a fourth eNB () belongs to a third TA () to which a tenth eNB () belongs. Upon change of the TA of the RN () as described above, a user equipment device (UE;) transmits a TA update request signal of the own device to a target second MME ().
