Abstract
A relay gateway apparatus (HandOver-Gateway (HO-GW) is provided between heterogeneous access networks (a WiMAX access network and a UMB access network). The HO-GW performs conversion of a movement control signal (an Inter-Access Gateway (AGW) handover control signal) and relay of communication data. When the relay is performed, user data from a correspondent node (CN) reaches a wireless terminal (mobile node (MN)) through a host agent (HA) of a core network, an access router ASN-GW, the HO-GW, and a base station eBS.
