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