Abstract
A method and apparatus for mobile relay node tracking area configuration and location update. The method includes: configuring a dedicated tracking area for a Donor eNodeB (DeNB); configuring a dedicated tracking area for a mobile Relay Node (RN) accessing the DeNB; when a terminal (UE) accessing the mobile RN registers or tracking area updates, allocating a tracking area identifier list containing the dedicated tracking area to the UE; the dedicated tracking area is a tracking area code dedicated to a mobile relay. The method and apparatus try the best to guarantee that a paging area list allocated to the UE contains the tracking area configured for the mobile relay serving the UE, thereby avoiding that numerous UEs served by the RN trigger location update simultaneously in the process of the RN moving.
