Abstract

A roaming-service-enabling system is provided which enables a user to gain access to desired contents and/or to be provided with desired service from any kind of internet connecting device. An SRF (Service Roaming Framework) server has a network controlling unit, subscriber profile storing unit, and subscriber authenticating unit. The subscriber profile storing unit stores information about a type of an access terminal that a user is able to use and subscriber profile information used to identify an access unit corresponding to the access terminal. The network controlling unit transmits data fed from a service providing server to the access terminal by making the data be matched to the type of the access terminal and access unit according to subscriber profile information being stored by the subscriber profile storing unit.

Claims

1. A roaming-service-enabling system for giving an arbitrary service provided by a service providing server to two or more types of terminals being used by a user, said system comprising:

a roaming server comprising a profile storing unit to store information about said two or more types of terminals that the user is able to use and profile information to be used to identify a transmission path corresponding to each of said two or more types of terminals and a network controlling unit to transmit data fed from said service providing server to an arbitrary terminal selected among said two or more types of terminals, by matching the data to a type of said arbitrary terminal and to the corresponding transmission path according to the profile information being stored in said profile storing unit.

2. The roaming-service-enabling system according to claim 1, wherein said roaming server has an authenticating unit to judge, by using information which is fed from the arbitrary terminal and is used for authentication, whether or not the user going to be provided with service by using said arbitrary terminal is qualified to be provided with service.

3. The roaming-service-enabling system according to claim 1, wherein said arbitrary terminal that the user is able to use is connected to the Internet via a server in an internet service provider which provides internet connecting service and wherein said profile storing unit and network controlling unit are mounted in said server.

4. The roaming-service-enabling system according to claim 1, wherein said service providing server is a server that issues an account of electronic-mail.

5. The roaming-service-enabling system according to claim 1, wherein said service providing server is a contents distributing server.

6. The roaming-service-enabling system according to claim 1, wherein said service providing server is a server which provides speech service using an internet protocol.

7. The roaming-service-enabling system according to claim 1, wherein said network controlling unit converts a protocol that said service providing server uses to a protocol being matched to said arbitrary terminal and transmits data fed from said service providing server to said arbitrary terminal.

8. The roaming-service-enabling system according to claim 1, wherein said network controlling unit converts a descriptive language of data fed from said service providing server to a descriptive language being matched to said arbitrary terminal.

9. A roaming-service-enabling method in a roaming server for giving an arbitrary service provided by a service providing server to two or more types of terminals being used by a user, said method comprising:

a step of storing information about said two or more types of terminals that a user is able to use and profile information to be used to identify a transmission path corresponding to each of said two or more types of terminals;

a step of judging, by using information which is fed from an arbitrary terminal selected among said two or more types of terminals and is used for authentication, whether or not the user going to be provided with service by using said arbitrary terminal is qualified to be provided with service; and

a step of transmitting data fed from a service providing server to the arbitrary terminal, by matching the data to a type of said arbitrary terminal and to the corresponding transmission path according to the stored profile information.

10. A roaming-service-enabling program installed in a roaming server for giving one service provided by a service providing server to two or more types of terminals being used by a user to have said roaming server execute processing, said processing comprising:

a process of storing information about said two or more types of terminals that a user is able to use and profile information to be used to identify a transmission path corresponding to each of said two or more types of terminals;

a process of judging, by using information which is fed from an arbitrary terminal selected among said two or more types of terminals and is used for authentication, whether or not the user going to be provided with service by using said arbitrary terminal is qualified to be provided with service; and

a process of transmitting data fed from a service providing server to the arbitrary terminal, by matching the data to a type of said arbitrary terminal and to the corresponding transmission path according to the stored profile information.
