As the telecommunications and IT industry converge towards an M-ICT future, so bearer networks will need to develop in the direction of convergence. Bearer network convergence is reflected in three aspects: architecture, technology and management.
1) Architecture convergence: Vertically the convergence means the reduction of network connections while horizontally the convergence enables one network to transport all services.
2) Technology convergence: Packet and optical convergence flattens the network to greatly reduce CAPEX.
3) Management convergence: A unified network management platform makes operation and maintenance easier.
In the M-ICT era, mobile multimedia service usage will continue to gain widespread adoption. With the current network and service structure, some large-traffic services, such as HD and super HD mobile videos, will flood the entire network. On a 5G network, services that directly affect user experience will be provided by both the network and the cloud. Therefore, deep convergence of both services and the network will significantly improve user experience and reduce CAPEX and OPEX.
