Abstract
A method for handover in a wireless communications network includes the step of communicating information between a target network node and a source network node to enable the source network node to identify and to distinguish types of failures prior to, during or after handover. The information may relate to: “Handover command not received” due to RLF prior to handover or Handover command failure experienced in the source cell; or “Handover failure” where “Handover command received” is followed by Access failure in the target cell. The method is applicable, for example, to networks in accordance with LTE.
