Abstract

A mobile communication system includes at least one mobile terminal that can access a circuit switched network and a wireless broadband network, and a node apparatus. The node apparatus integrates, into one physical node, a first gateway node interconnecting the circuit switched network and an IP network and a second gateway node interconnecting a core network accommodating the wireless broadband network and an external packet data network. When the mobile terminal performs handover from one of the circuit switched network and the wireless broadband network to the other network, one of the first gateway node and the second gateway node, being a handover-destination node, allocates call connection path node identification information managed by the other gateway note being a handover-source node, as new call connection path node identification information of the handover-destination node.
