The serving gateway (SGW) is adapted for entering a state of ECM-IDLE () and ECM-CONNECTED () for a user entity (UE) in question. The serving gateway upon reception of a Modify Bearer Request message () may effectuate a setting up one or more user plane tunnels between the serving gateway (SGW) and a base station (eNodeB).
