Abstract

A method and system for improving a call drop caused by a Radio Link Failure (RLF) before handover triggering in a mobile communication system are provided. The method of improving the call drop caused by the RLF in the mobile communication system includes detecting an RLF occurring before handover triggering (RLF_before_HO), generating one of an RLF_before_HO-dependent statistics and an RLF_before_HO-dependent log file, transmitting the one of the RLF_before_HO-dependent statistics and the RLF_before_HO-dependent log file to a serving Base Station (BS), and updating a Neighbor Relation Table (NRT) and optimizing a handover parameter using the one of the RLF_before_HO-dependent statistics and the RLF_before_HO-dependent log file.
