Abstract  Abstract

The present invention relates to a mobile node located within a non-3GPP / 3GPP network, and a method for handing the mobile node from a non-3GPP network to a 3GPP network. Handover can be improved by discovering an appropriate MME in advance and registering a mobile node with the found MME. This includes determining the location of the mobile node in the non-3GPP network so that the MME near the location of the mobile node can be detected. Before the handover is performed, the 3GPP context is sent to the new MME. In addition, the present invention accelerates handover by teaching to change the serving gateway in the 3GPP network before performing the handover. When handover is likely to occur, the location of the mobile node is determined and a new serving gateway is selected. The data path is changed to pass through the new serving gateway.
