Claim:
1. A coverage hole detection apparatus, comprising: a transceiver interface, being configured to receive a first time length, a second time length, a piece of first location information, and a piece of second location information, wherein the first time length is from a time point when a first user equipment (UE) has detected a disconnection from a first base station to a time point when the first UE determines that a Radio Link Failure (RLF) has happened, the second time length is from a time point when the first UE receives an RLF report request from a second base station to a time point when the first UE transmits an RLF report response to the second base station, the piece of first location information indicates a location where the first UE determines that the RLF has happened, and the piece of second location information indicates a location where the first UE transmits the RLF report response; and a processing unit, being electrically connected to the transceiving interface and configured to calculate a first distance according to the first time length and a moving velocity, calculate a second distance according to the second time length and the moving velocity, decide a first boundary location of a coverage hole according to the piece of first location information and the first distance, decides a second boundary location according to the piece of second location information and the second distance, and decide the coverage hole according to the first boundary location, the second boundary location, and a first sensitivity range of the first UE.
