Method and apparatus for handover by implementing pre-handover indication messages for a preferred target node in wireless telecommunication networks
Abstract:
A method for handover of a mobile terminal from a source node to a target node in a wireless telecommunications network, including the steps of: adding an indication in the preparation phase by which source node indicates to the target node if it is the one preferred or not. If a target node is not the one preferred but is still selected by the UE, it may indicate this to the source node as by a specific new message that comes earlier in the handover process than a message requesting the source node to release resources following successful handover to a new node. The source node can then in this case cancel handover preparations to other target nodes earlier and also start data forwarding where applicable earlier.
