ABSTRACT:
A data transfer system and its method, in which a plurality of U-plane controllers are connected to one C-plane controller and the number of the U-plane controllers is increased or decreased to realize a network structure of a low cost and to meet various conditions and requirements. Each U-plane controller sends at lease one of network traffic conditions, resource using conditions within itself and trouble conditions to the C-plane controller. The C-plane controller selects an optimum U-plane link for providing a user terminal with services and requests a core network to carry out a U-plane link exchange via an optimum U-plane controller. The core network carries out the U-plane link exchange.
