Abstract:
The present invention relates to a method, a user equipment and a network node in a cellular radio network. According to the method of the present invention, the network units detects a failed transmission of a handover command to the UE, which is still having a uplink channel available, and further receives a RRC message from the UE indicating the loss of a serving cell and indicating the strongest cell. The network unit prepares and initiates a new serving cell re-establishment and sends to the UE a RRC reconfiguration message. The UE can then continue normal operation in the new cell.
