Abstract
The present invention relates to methods and arrangements in a UE and a RBSin a wireless communications system, enabling an efficient handover of the user equipment. The method comprises transmitting (810) a message to the serving radio base station, the message indicating the need for a handover to a cell of a target radio base station. It also comprises observing (820) an indication that a handover request transmitted by the serving radio base station is rejected by the target radio base station, and selecting (830) a recovery cell based on the observed indication when detecting a radio link failure.
