Disclosed is a method for managing multiple remote radio heads (RRHs) in a communication network, including, in response to an occurrence of an alarm indicating that a value of an operation parameter of an RRH among the multiple RRHs is beyond a predetermined range, determining whether the RRH is faulty by using a model for detecting a fault in the RRH, based on one or more pieces of operation information of the RRH which respectively correspond to multiple timestamps, and issuing a notification indicating that the RRH is faulty when it is determined that the RRH is faulty.
