<p>A session control method for radio terminals that implements a Multimedia Integrated network by Radio Access Innovation (MIRAI) such that selection of a radio access network does not impose a burden on each of the radio access networks, and an interface setup method for setting up IP connection quickly during switching of the radio access network. The Multimedia Integrated network by Radio Access Innovation (MIRAI) 10 includes heterogeneous radio access networks 11, Internet 12, and multimode radio terminals 13 , and the heterogeneous radio access networks 11 includes a PHS network 11 a, a wireless LAN 11 b, a paging network 11 c, and a cellular phone network 11 d. The Internet 12 includes a CCN server 12 a, which sends session-related information to the radio terminal 13 via the paging network 11 c. The radio terminal 13 selects a radio IF and application that are appropriate for communication based on the session-related information, and establishes a session.</p> |
