METHOD FOR SELECTING NETWORK FOR BETWEEN HETEROGENEOUS RADIO ACCESS NETWORKS

摘要

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.
