Abstract:
The invention regards a handover method for a data packet based wireless mobile communications network. The network comprises a core network (CN) and a radio area network (RAN). The core network (CN) comprises a control plane node (MME) intercommunicating with a user plane node (UPE). The radio area network comprises a mobile user equipment (UE) intercommunicating with a source radio base transceiver station, eNOdeB, (source eNodeB), wherein payload data is routed via a tunnel between the user plane node (UPE) and the source eNodeB (source eNodeB), wherein the handover comprises the step of establishing a temporary tunnel between the user plane node (UPE) and a target eNodeB (target eNodeB), the handover being initiated by the target eNodeB (target eNodeB) transmitting an unreliable uplink data signal to the user plane node (UPE) comprising handover information.
