Abstract
In a mobile communication system including a mobile station, an access apparatus for performing connection control between the mobile station and an access network, and an access network switching apparatus for switching access networks to communicate with the mobile station, the mobile station establishes a first path to communicate with the access apparatus, when the mobile station enters a coverage area of the access apparatus. The access apparatus establishes a second path to communicate with the access network switching apparatus when the first path is established. The access network switching apparatus switches the access networks when a predetermined condition is satisfied.
