Service shifting method, shift management server, terminal, service server, service shift program and service shift system

A transfer management server which manages transfer of service being used by a transferring source terminal to a transferring destination terminal, the transfer management server comprising:

• a relation information storage unit which records information about a relation between a session identification (ID) and a terminal identification (ID) of said transferring source terminal using said service in at least one of a service server and a transfer management server, the session ID identifying a session between said service server which provides said service and said transferring source terminal;
• and
• a transfer management unit which updates the information about the relation between the session ID and the terminal ID recorded in either the service server or the transfer management server upon receiving, from one terminal of the transferring source terminal and the transferring destination terminal, a terminal ID of the one terminal and a terminal ID of the other terminal of the transferring source terminal and the transferring destination terminal so that the session ID and the terminal ID of the transferring destination terminal relate with each other, and which, when a request for obtaining the session ID related to the terminal ID of said transferring source terminal or the transferring destination terminal is made from said service server having received a service request from said transferring destination terminal, notifies said service server of the session ID related to the terminal ID of said transferring source terminal or the transferring destination terminal by referring to said relation information,
• wherein the service server stores session information on the service used by the transferring source terminal, and provides the service for the transferring destination terminal using the session information identified by the received session ID.

A terminal which uses service provided by a service server, the terminal comprising:

• a terminal identification (ID) storage unit which stores a terminal identification (ID) applied to the terminal;
• at least one client application that transmits said terminal ID to said service server to make a service request;
• and
• a service transfer management unit which transmits a terminal ID of another terminal as a transferring source or a transferring destination for a service and said terminal ID of the terminal to a transfer management server which stores information about a relation between a session identification (ID) which identifies a session between said service server and the transferring source terminal using the service and the terminal ID of said transferring source terminal to notify transfer of service between the terminals,
• wherein the service transfer management unit updates the information of the relation between the session ID and the terminal ID recorded in either one of the service server or the transfer management server upon receiving, from one terminal of the transferring source terminal and the transferring destination terminal, the terminal ID of the one terminal and the terminal ID of the other terminal so that the session ID and the terminal ID of the transferring destination terminal relate with each other, and transmits the session ID related to the received terminal ID to the service server, and
• the service server stores session information on the service used by the transferring source terminal, and provides the service for the transferring destination terminal using the session information identified by the obtained session ID upon receiving the request from the transferring destination terminal and obtaining the session ID.

A service server which provides a terminal with service, comprising:

• a session information storage unit which stores information about a session with said transferring source terminal using said service,
• wherein the service server is configured to transmit a session identification (ID) which identifies said session information and a terminal identification (ID) of said transferring source terminal to a transfer management server which records information about a relation between said session ID and the terminal ID of said transferring source terminal, and updates the information about the relation between the session ID and the terminal ID recorded in either of the service server or the transfer management server upon receiving, from one terminal of the transferring source terminal and the transferring destination terminal, a terminal ID of the one terminal and a terminal ID of the other of the transferring source terminal and the transferring destination terminal so that the session ID and the terminal ID of the transferring destination terminal relate with each other, and
• the service server is configured to obtain the session ID related to the terminal ID of said transferring source terminal or the transferring destination terminal from said relation information of said transfer management server upon receiving a service request from said transferring destination terminal and transmitting said obtained session ID to said transferring destination terminal, and is configured to provide the service for the transferring destination terminal using the session information identified by the session ID.

A program to be executed on a terminal that uses service provided by a service server, which causes said terminal to execute a method, comprising:

• transmitting a terminal identification (ID) applied to the terminal to said service server to make a service request;
• transmitting said terminal ID of another terminal as a service transferring source or transferring destination and said terminal ID of the terminal to a transfer management server which stores information about relation between a session identification (ID) which identifies a session between said service server and the transferring source terminal using the service and the terminal ID of said transferring source terminal to notify transfer of the service between the terminals;
• updating, by the transfer management server, the information about the relation between the session ID and the terminal ID recorded in either the service server or the transfer management server upon receiving, from one terminal of the transferring source terminal and the transferring destination terminal, the terminal ID of the one terminal and the terminal ID of the other terminal;
• and
• storing, by the service server, session information on the service used by the transferring source terminal, and providing the service for the transferring destination terminal by using the session information identified by the received session ID upon receiving the terminal ID from the transferring destination terminal to make the service request.

A program to be executed on a transfer management server that manages transfer of service being used by a transferring source terminal to a transferring destination terminal, which causes said transfer management server to execute a method, comprising:

• recording, in a relation information storage unit, information about a relation between a session identification (ID) and a terminal identification (ID) of said transferring source terminal using said service in at least one of a service server and a transfer management server, the session ID identifying a session between said service server which provides said service and said transferring source terminal;
• updating the information about the relation between the session ID and the terminal ID recorded in either of the service server or the transfer management server upon receiving, from one terminal of the transferring source terminal and the transferring destination terminal, the terminal ID of the one terminal and the terminal ID of the other of the transferring source terminal and the transferring destination terminal so that the session ID and the terminal ID of the transferring destination terminal relate with each other;
• referring to said relation information to notify said service server of the session ID related to the terminal ID of said transferring source or transferring destination terminal when a request for obtaining a session ID related to the terminal ID of said transferring source or transferring destination terminal is made from said service server having received a service request from said transferring destination terminal;
• and
• storing, by the service server, session information on the service used by the transferring source terminal, and providing the service for the transferring destination terminal by using the session information identified by the received session ID upon receiving the terminal ID from the transferring destination terminal to make the service request.
