Method and device for managing multiple remote radio heads in communication network

A device for managing multiple remote radio heads (RRHs) in a communication network, the device comprising:

• a communication interface;
• a memory;
• and
• a processor connected to the communication interface and the memory, wherein the processor is configured to:
• 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, determine 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
• issue a notification indicating that the RRH is faulty when it is determined that the RRH is faulty,
• wherein the one or more pieces of operation information of the RRH comprises at least one of information related to an uptime of the RRH, information related to a type of the alarm, information related to a state of the RRH, and information related to an environment of the RRH.
