<p>A method for detecting a cause of radio link failure (RLF) or handover failure, in which the first base station triggers a handover process for the UE, and the mobility or handover information of the UE in the source cell is sent to a second base station. After the second base station receives the RLF report of the UE, the second base station can determine cause of a failure according to the RLF report of the UE and the mobility or handover information of the UE in the source cell. Other methods detect a cause of radio link failure (RLF) or handover failure. Application of the methods can improve the accuracy of determining the cause of the RLF or handover failure, improve efficiency of MRO and improve system performance.</p> |
