Abstract: Constructed is a network management system which manages, in an integrated manner, a first communication system, a second communication system and a third communication system passed through by packets that are sent and received via wireless communication between a first device and a second device. The network management system performs information setting to these communication systems for dividing a communication system group, which includes these communication systems, into a plurality of logical partitions each corresponding to a plurality of different service levels based on the management information of each of these communication systems. A logical partition corresponding to a service level with regard to each of the plurality of different service levels is a partition passed through by packets that are sent and received via wireless communication between the first device and the second device belonging to that service level.

Abstract: From among a U-plane and a C-plane, the U-plane is installed in a first user site which has a base station, and the C-plane is installed in a C-plane site (any site that is not a user site). A system sets a U-plane inter-site path which is an inter-site communication path that connects a first user site with a second user site via a wide area network, and a C-plane inter-site path which is an inter-site communication path that connects a C-plane site with the first user site via the wide area network. In addition, the system sets an in-site communication path which is a communication path within the first user site and which connects to an inter-site communication path. A U-plane inter-site path is an inter-site communication path via which data is transmitted or received by a U-plane. A C-plane inter-site path is an inter-site communication path via which a signal is transmitted or received by a C-plane.
