In this paper, we analyze the concept of network convergence and characteristics of Broadband convergence Network(BcN) from the service perspective where convergence would appear. We suggest the evolutionary 3 stage steps of BcN as an ideal network strategy when considering present network situation. We also propose the features of several representative services that are expected to emerge out of network convergence.
