Integrated element management system for end-to-end network management in next generation network, and network management method thereof

摘要

When an integrated EMS (Element Management system) receives an open command for a new subscriber from a telephone office, it forwards the open command to a relevant network element, which will provide a communication line to the subscriber, to perform an open operation, receives, from the relevant network element, physical connection information allocated to the relevant subscriber terminal by the network element and logical subscriber information allocated to the relevant subscriber by a softswitch according to the subscriber open, and stores the information in a database. The EMS performs a virtual management switch function based on the information in the database to manage a link state and correlated information between respective network elements (NEs). The EMS performs the end-to-end management of alarm, configuration, performance, or the like from the subscriber end to the softswitch by interconnecting a logical number of a subscriber (telephone number) and a physical number of a subscriber node (subscriber connection port ID and position information) as well as link information between the network elements, through the virtual management switch function. Accordingly, there is provided an advantage that a communication path from the softswitch to the subscriber terminal in the next generation network can be collectively managed.
