Method for establishing communication path between heterogeneous radio access networks
First Claim
1. A method for establishing a new data transmission path to a correspondent node (CN) by a mobile node (MN) connected to a first radio network after moving to a second radio network having an access scheme that is different than the access scheme of the first radio network the method comprising the steps of:
- transmitting, by the MN, network information received from the second radio network and location information of the CN to a base station (BS) constituting the first radio network;
determining by the BS whether it can establish a data transmission path between the second radio network and the CN, using network contract information of the first radio network, network information of the second radio network, and the location information of the CN;
if the BS can establish the data transmission path, determining a data transmission path between the second radio network and the CN using the network contract information of the first radio network, the network information of the second radio network, and the location information of the CN;
transmitting information on a radio network to which the CN is connected in the determined data transmission path, to the MN; and
establishing, by the MN, a connection to the second radio network, and communicating with the CN via the data transmission path.

Abstract
A mobile node (MN) connected to a first radio network transmits location information of a correspondent node (CN) to a base station (BS) constituting a second radio network. The BS determines whether it can establish a data transmission path to the CN, using network contract information of the second radio network and the location information of the CN. If the BS can establish the data transmission path, it determines a data transmission path to the CN using the network contract information of the second radio network and the location information of the CN, and transmits an identifier (ID) of the second radio network and service connection possibility/impossibility information to the MN. The MN establishes a connection to the second radio network, and communicates with the CN via the data transmission path.
