摘要： A BS 11 recognizes states of a first session and a second session and instructs an MS 12 to change a state of the first session via the second session when the BS 11 receives data for the first session from a network while the first session is in the sleep state and the second session is in the active state. When the MS 12 changes the first session to be in the active state before a lapse of predetermined time interval when receiving the instruction from the BS 11, the BS 11 transmits the data for the first session to the MS 12 via the first session changed to be in the active state.

摘要： An authentication server according to the present invention performs authentication of a first access to the Internet via a base station, and stores a usable base station identifier identifying a radio base station usable by the radio terminal to access the Internet. When a base station identifier of a different base station being a handover candidate of the radio terminal matches the usable base station identifier stored in advance, the authentication server transmits an authentication request to an authentication server managing the different base station, the authentication request requesting authentication of a second access to the Internet via the different base station.
