Radio terminal session control and interface set up method
First Claim
1. A session control method for radio terminals used in a Multimedia Integrated network by Radio Access Innovation (MIRAI) that comprises a plurality of dissimilar radio access networks and the Internet that connects among said radio access networks, wherein one of said radio access networks is employed as a signaling network;
- a server is provided in said Internet such that when a request or connection with said radio terminal is made, session-related information required for the connection is sent to said signaling network;
said radio terminal includes a plurality of radio interfaces and a plurality of applications, as well as an agent portion; and
said agent portion allows a radio interface corresponding to said signaling network among a plurality of radio interfaces to be retained in the standby condition, and allows the radio interface in the standby condition to receive said session-related information, so that an application and radio interface that are suitable for communication are selected among said plurality of applications and said plurality of radio interfaces, respectively, based on said session-related information, to establish a session.

Abstract
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 11a, a wireless LAN 11b, a paging network 11c, and a cellular phone network 11d. The Internet 12 includes a CCN server 12a, which sends session-related information to the radio terminal 13 via the paging network 11c. 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.

3. AN interface setup method for a Multimedia Integrated network by Radio Access Innovation (MIRAI) that comprises a plurality of dissimilar radio access networks and the Internet that connects among said radio access networks, wherein:
-
a server is located in said Internet to acquire ad-hoc authentication information against an access network server of each service provider that make IP connection respectively with an access point of said radio access network;
a radio terminal is equipped with a plurality of radio interfaces, as well as an agent portion;
said interface setup method comprising the steps of;
detecting beforehand, by said agent portion, switching of the radio access beforehand, by said agent portion, switching radio access network, sending information related to the target radio access network to said server located in the Internet;
identifying, by said server located in the Internet, said access network server that makes IP connection with the access point of the target radio access network, abased on said information related to the target radio access network;
acquiring ad-hoc authentication information against the access network server; and
sending information required for IP connection, together with the ad-hoc authentication information, to said agent portion;
sending, by said agent portion, said ad-hoc authentication information to said access network server, so that said ad-hoc authentication information activate connection with said access network server; and
sending by said agent portion, information required for IP connection to said access network to make IP connection, when connection to said access network server is activated.
