A method for managing links, performed by a first communication node in a communication system, includes: obtaining, through an interface, communication status information including communication quality information for each link between the first communication node and at least one other communication node of the communication system; obtaining communication environment information including movement information and location information of each of the at least one other communication node; and obtaining a link probability computational model outputting a first link probability according to input of the communication status information by iteratively performing a machine learning operation based on the communication status information and the communication environment information, wherein the first link probability is used by the first communication node to control multi-connectivity with the at least one other communication node.
