Abstract
A coverage hole detection apparatus and method are provided. The coverage hole detection apparatus decides two boundary locations of a coverage hole according to (a) a time length from a time point when a user equipment (UE) has detected a disconnection from a first base station to a time point when the UE determines that a Radio Link Failure (RLF) has happened, (b) a time length from a time point when the UE receives an RLF report request from a second base station to a time point when the UE transmits an RLF report response to the second base station, (c) a location that the UE determines that the RLF has happened, and (d) a location where the UE transmits the RLF report response. The coverage hole detection apparatus decides the coverage hole according to the two boundary locations and a sensitivity range of the UE.
