Abstract:
In one aspect, a method for a packet gateway node (PGW) is disclosed. The PGW being adapted for (a) communicating with at least a serving gateway node, SOW, (b) receiving and forwarding downlink data packets to a user entity, UE, and (c) communicating with a mobility management entity, MME. In one embodiment, the method comprises: the PGW, when receiving a downlink user plane data packet destined for the UE on a Packet Data Network, PDN, connection associated with a restarted SGW, determining if the PDN connection has not yet been relocated to a new SGW, and, if so, selecting at least one SGW from a set of SGWs including the restarted SGW or another SGW and transmitting a control plane signal to at least one of the selected SGWs, the control plane signal identifying at least the UE.
