More Information
Summary:A method for enhancing mobility robustness in a wireless communications network includes communicating information between a selected 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.
