Reference model of broadband convergence network in Korea

Korean operator has started BcN implementation plan by replacement of class 5 switching system with access gateway, implementation of trunk gateway, application servers, Softswitch, new BcN premium backbone network, replacement of toll/tandem switch with trunk gateway, interconnection of 3G mobile to BcN, expansion of application server and 3
^rd
party, and finally replacement of all class 5 switching system with access gateway. The development purpose of BcN reference model is to propose standard model of network vision, roadmap, requirements for the network architecture, and BcN service scenario and interworking issues which were suggested at Korean operator's BcN implementation plan. While, our BcN test bed can be used for the verification of network equipments and interworking between telecom operators and vendors. Based on our reference model, Korean BcN would be improved to provide various multimedia services.
