A base station and a method that reduce abnormal cell re-selection behaviors. The base station includes: a detection module having a pattern information detector that provides pattern information of an almost blank subframe, and a measurement configuration adjustor that provides a first parameter threshold for cell-selection and generates a second parameter threshold for cell-selection according to the pattern information; and a measurement configuration generating module having a measurement configuration schedule generator that generates a broadcasting schedule according to the pattern information, a system information broadcaster that transmits first schedule information to first user equipment when the first user equipment establishes connection to allow the first user equipment to receive the first parameter threshold according to the first schedule information and perform cell-selection, and a dedicated signal generator that generates a dedicated signal and transmits second schedule information to second user equipment when the second user equipment establishes connection.
