Claim Text:
1. A method of handling Radio Link Failure (RLF) Reports in a radio access network, wherein different Radio Access Technologies (RATs) are utilized in different areas served by the radio access network, and a User Equipment (UE) is configured to generate and store an RLF Report when the UE experiences a radio link failure at a first access node that utilizes a first RAT and the UE reconnects to a second access node that utilizes a second RAT, wherein the method is performed in a third access node, which utilizes the first RAT, the method comprising: receiving at the third access node, the RLF Report from the UE when the UE subsequently connects to the third access node; determining that the third access node does not have a direct connection to the first access node for forwarding the RLF Report to the first access node; determining that receiving the RLF Report has caused a threshold value to be exceeded; generating an event log containing RLF reports for the first access node; and making the event log available to the network, wherein making the event log available includes sending performance traces to a network management node, wherein the performance traces encapsulate the RLF reports indicating radio link failures in the first access node, wherein the network management node forwards to the first access node, the RLF reports received in the performance traces from the third access node.
